After the phosphorus breaking roller works for a period of time, the abrasion of the abrasive wire on the surface can not be continued for rust removal. In order to save consumables, the steel belts and the steel wires in the brush bar are required to be separated and recycled.

In a further aspect, the diameter of the second drive gear is greater than the diameter of the first drive gear. Because the diameter of the second driving gear is larger than that of the first driving gear, the winding speed of the steel wire is faster than that of the steel belt, and the steel wire is firstly pulled out of the steel belt, so that the influence on the feeding of the steel belt is avoided.

Detailed Description

For a further understanding of the present invention, reference should be made to the following detailed description of the invention, taken in conjunction with the accompanying drawings and detailed description.

In the description of the present invention, it should be understood that the terms "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," and the like indicate orientations or positional relationships based on the orientation or positional relationships shown in the drawings, merely to facilitate describing the present invention and simplify the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be configured and operated in a specific orientation, and thus should not be construed as limiting the present invention.

Referring to fig. 1-24, the present embodiment provides a brush bar recycling apparatus, which includes a frame 1, the frame 1 has a head end and a tail end along a length direction thereof, the head end of the frame 1 is provided with a brush bar unreeling reel 2 and a steel wire reeling reel 3, both the brush bar unreeling reel 2 and the steel wire reeling reel 3 can rotate relative to the frame 1, wherein the brush bar unreeling reel 2 winds a brush bar to be processed.

The frame 1 is provided with a brush bar guiding mechanism 4, an abrasive wire removing mechanism 5 and a steel belt reducing mechanism 6 in sequence along the conveying direction of the steel belt. As shown in fig. 8-11, the brush bar guiding mechanism 4 comprises a fixed block 8, a rotating shaft 9, a connecting rod 10, a guiding rod 11, a limiting plate 12 and a limiting assembly 13. The fixed block 8 is fixedly arranged on the frame 1, the limiting plate 12 is fixedly arranged on the fixed block 8, and the rotating shaft 9 is rotatably arranged on the fixed block 8. The head end of the connecting rod 10 is fixedly connected with the rotating shaft 9, and the extending direction of the connecting rod 10 is perpendicular to the extending direction of the rotating shaft 9. The guide rod 11 is connected with the tail end of the connecting rod 10, and the extending direction of the guide rod 11 is perpendicular to the extending directions of the connecting rod 10 and the rotating shaft 9 respectively. The limiting assembly 13 acts on the shaft 9 or the connecting rod 10. When the rotating shaft 9 drives the guide rod 11 to rotate to a designated position relative to the fixed block 8, the limiting component 13 forces the guide rod 11 and the fixed block 8 to remain fixed relative to each other. A feed channel 14 for passing through the brush bar is formed between the guide bar 11 and the limiting plate 12.

It will be readily appreciated that when the lengths of the wound brush strips are different, the diameters of the brush strip rolls are different after the brush strips are wound on the winding disc, and the brush strip rolls are different in diameter, so that the brush strips enter the abrasive wire removing mechanism 5 at different heights to remove wires. And drive guide bar 11 through pivot 9 and rotate for fixed block 8, adjust the position of guide bar 11 for the brush strip can be through the feed channel 14 entering abrasive wire that forms between guide bar 11 and the limiting plate 12 all the time and get into abrasive wire removal mechanism 5, carries out spacingly to the left and right sides of brush strip through guide bar 11 and limiting plate 12, avoids the brush strip to rock in the transportation process and influences follow-up abrasive wire to remove silk and steel band reduction. And in the process of unreeling the brush strip unreeling disc 2, although the diameter of the brush strip reel on the brush strip unreeling disc 2 can be changed, the limit of the guide rod 11 can not be lost in the process of unreeling the brush strip due to the fact that the guide rod 11 has a certain length.

In order to avoid abrasion of the brush bar caused by friction between the guide rod 11 and the side wall of the brush bar, the guide rod 11 is also sleeved with a rotary drum 15, and the rotary drum 15 can rotate around the axis direction of the rotary drum relative to the guide rod 11. In the process of conveying the brush strips, the brush strips are propped against the outer wall of the rotary drum 15, and the friction force between the brush strips and the fixed rod is converted into rolling friction between the brush strips and the rotary drum 15 through the rotary drum 15, so that the friction force is reduced, and abrasion of the brush strips is avoided.

In this scheme, as shown in fig. 8, the limiting component 13 includes a limiting rod 16, an arc through groove 17 is disposed on the limiting plate 12 around the rotating shaft 9, the limiting rod 16 penetrates through the arc through groove 17, and the head end of the limiting rod 16 is connected with the connecting rod 10. As a preferred embodiment, the limiting assembly 13 further includes a connecting member 18, the connecting member 18 is disposed at a head end of the limiting rod 16, and the head end of the connecting member 18 is provided with a fork-shaped body 19. The fork-shaped body 19 comprises two fork plates which are oppositely arranged, the connecting rod 10 is penetrated in a fork groove formed between the two fork plates and is matched with the fork-shaped body 19 in a clamping way, and then the head end of the limiting rod 16 is connected with the connecting rod 10. Meanwhile, a limit nut 20 is screwed to the tail end of the limit rod 16. When the rotating shaft 9 drives the guide rod 11 to rotate relative to the fixed block 8, the limiting rod 16 slides in the arc-shaped through groove 17. When the rotating shaft 9 drives the guide rod 11 to rotate to a designated position relative to the fixed block 8, the guide rod 11 and the limiting plate 12 can be kept relatively fixed only by twisting the limiting nut 20 to force the limiting nut 20 to be clung to the limiting plate 12, and the structure is simple and the operation is convenient.

When the center of the circle corresponding to the arc-shaped through groove 17 has a certain deviation from the axis position of the rotating shaft 9, the connecting rod 10 may not drive the limit rod 16 to slide in the arc-shaped through groove 17 during rotation, and the limit rod 16 is blocked in the arc-shaped through groove 17. At this time, since the connecting rod 10 is engaged with the fork 19 on the connecting piece 18, the connecting piece 18 and the stop lever 16 are removed first, the connecting rod 10 and the guide lever 11 are rotated to the designated position, and then the connecting piece 18 is inserted into the arc-shaped through slot 17, so that the connecting rod 10 passes through the fork slot again, and the stop nut 20 at the tail end of the stop lever 16 is screwed to complete the fixing.

It should be noted that, although the limiting rod 16 and the nut are matched with the arc-shaped through groove 17 to limit the connecting rod 10 and the guide rod 11 in the present embodiment, other fixing modes in the prior art may be adopted, for example, a plurality of through holes are formed in the limiting plate 12 around the axis of the rotating shaft 9, a bolt is disposed on the connecting rod 10, and when the rotating shaft 9 drives the guide rod 11 to rotate to a designated position relative to the fixed block 8, it is also feasible to insert the bolt into the corresponding through hole to achieve fixing.

It should be noted that, although in the present solution, the limiting component 13 acts on the connecting rod 10, but the limiting component 13 acts on the rotating shaft 9, for example, a plurality of through holes are circumferentially arranged on the rotating shaft 9, and bolts are arranged on the fixed block 8, so that when the rotating shaft 9 drives the guide rod 11 to rotate to a designated position relative to the fixed block 8, it is also feasible to insert the bolts into the corresponding through holes to realize fixation.

The frame 1 is further provided with a wire recovery mechanism 94, referring to fig. 1-7, the wire recovery mechanism 94 includes the wire winding disc 3, and further includes a guiding filter 22 and a limiting member, and the guiding filter 22 is provided with a filtering hole 23 through which only wires can pass. Firstly, a section of steel belt at the head end of the brush strip is restored to be flat, and steel wires on the steel belt are pulled away and wound on the steel wire winding disc 3 through the filter holes 23. It is easy to understand that the abrasive wire is also attached to the steel wire drawn from the brush bar, and if the steel wire is doped with the abrasive wire, the steel wire is rolled together, so that the rolling effect can be influenced, and the subsequent use of the steel wire can be influenced. When the steel wire passes through the filter holes 23 and is wound on the steel wire winding disc 3, the abrasive wire is blocked and removed by the filter holes 23 when the steel wire passes through the filter holes 23, so that the problem that the winding effect is affected when the abrasive wire is wound on the steel wire winding disc 3 along with the steel wire is avoided.

In this embodiment, the guiding filter 22 can slide up and down on the frame 1 along the vertical direction, and the limiting member acts on the guiding filter 22, when the guiding filter 22 slides to the designated position, the limiting member forces the guiding filter 22 to keep relatively fixed with the frame 1. The diameter of the steel wire coil after the steel wire coil 3 winds the steel wire is different for the brush strip coils with different diameters, and the steel wire coil with different diameters is not bent greatly when the steel wire passes through the guide filter hole 23 and winds the steel wire coil 3 because the guide filter piece 22 can slide up and down on the frame 1 along the vertical direction, and the height of the guide filter piece 22 can be adjusted according to the diameter of the steel wire coil.

As a specific embodiment, as shown in fig. 3 and 4, the limiting member includes a lifting rod 25, a fixing frame 24 is provided on the frame 1, a lifting through groove 26 extending along a vertical direction is provided on the fixing frame 24, the lifting rod 25 passes through the lifting through groove 26, a head end of the lifting rod 25 is connected with the guiding filter member 22, and a locking nut 27 is screwed at a tail end of the lifting rod 25. Before the steel wire is recovered, the guide filter piece 22 is pulled to drive the lifting rod 25 to slide to a designated position in the lifting through groove 26 according to the size of the pre-rolled steel wire roll, the locking nut 27 is turned around again, the locking nut 27 and the guide filter piece 22 clamp the two side walls of the fixing frame 24 to force the guide filter piece 22 to be relatively fixed with the fixing frame 24, and the steel wire winding machine is simple in structure and convenient to operate.

In this scheme, in order to avoid wire reel 3 to interfere with follow-up abrasive wire removing mechanism 5 and steel band reduction mechanism 6, wire reel 3 is located the top of brush strip unreeling reel 2 in the vertical direction, just wire reel 3 is located the front end of brush strip unreeling reel 2 in the horizontal direction. In order to enable the steel wires passing through the filter holes 23 to enter the steel wire winding disc 3 tangentially for winding, the guiding filter 22 comprises a connecting block 98 and a filter block 99, the tail end of the connecting block 98 is connected with the lifting rod 25, the head end of the connecting block 98 is connected with the filter block 99, and an included angle is formed between the filter block 99 and the connecting block 98 to form an L-shaped structure. And the filter block 99 has a front end face and a rear end face in the thickness direction thereof, and the filter holes 23 penetrate through the front and rear end faces of the filter block 99. And the filter hole 23 is a strip-shaped through hole, it is easy to understand that the diameter of the steel wire coil on the steel wire winding disc 3 can be changed in the winding process, and the steel wire can move up and down in the filter hole 23 along with the thickening of the steel wire coil through the strip-shaped through hole 23.

In this embodiment, as shown in fig. 6, the wire winding reel 3 includes a wind-up roller 28, and both ends of the wind-up roller 28 are respectively provided with a first limiting plate 29 and a second limiting plate 30. The first limiting plate 29 and the second limiting plate 30 are parallel to each other, and the first limiting plate 29 is detachably connected with the wind-up roll 28. The diameter of the wind-up roller 28 gradually decreases from the second limiting plate 30 to the first limiting plate 29. Because the diameter of the wind-up roller 28 is gradually reduced from the second limiting plate 30 to the first limiting plate 29, after the steel wire is wound on the wind-up roller 28, a certain gap exists between the steel wire coil and the wind-up roller 28, so that the subsequent steel wire coil can be taken conveniently.

Meanwhile, the steel wire recovery mechanism 94 further comprises a winding driving assembly, a supporting seat 31 and a rotating shaft 32, the head end of the frame 1 is vertically provided with a stand column 33, and the supporting seat 31 is arranged at the top end of the stand column 33.

The rolling driving assembly and the supporting seat 31 are both arranged on the frame 1, the rotating shaft 32 is rotatably arranged on the supporting seat 31, the rotating shaft 32 is connected with the steel wire rolling disc 3, as shown in fig. 5 and 7, a first sleeve 34 and a second sleeve 35 are sleeved on the rotating shaft 32, the first sleeve 34 is fixedly connected with the rotating shaft 32, the second sleeve 35 is rotationally connected with the rotating shaft 32 in the circumferential direction, a second friction disc 37 is arranged on the second sleeve 35, a first friction disc 36 is arranged on the first sleeve 34, and the first friction disc 36 is attached to the second friction disc 37. The winding driving assembly is connected with the second sleeve 35 and is used for driving the second sleeve 35 to rotate. When the second sleeve 35 rotates, the second friction plate 37 rotates along with it, the first friction plate 36 rotates together with the second friction force by the friction force between the first friction plate 36 and the second friction plate 37, and the first friction plate 36 drives the first sleeve 34 and the rotating shaft 32 to rotate, so as to drive the steel wire winding disc 3 to rotate. Specifically, the winding driving component in this embodiment is a winding driving motor 96.

As the number of wires wound around the wind-up roller 28 increases, the diameter of the wind-up roller 28 as a whole increases, the linear speed (winding speed) of the outer peripheral surface thereof increases, and the production speed of the wires is substantially stable, so that the tension to which the wires are subjected increases. When the static friction between the first friction plate 36 and the second friction plate 37 cannot overcome the tension of the steel wire, sliding will occur between the first friction plate 36 and the second friction plate 37, the angular speed of the wind-up roll 28 will be reduced accordingly, the linear speed of the outer peripheral surface will be reduced accordingly, and the tension borne by the steel wire will be reduced accordingly. When the tension borne by the steel wire is reduced to a certain extent, the friction force between the first friction plate 36 and the second friction plate 37 can overcome the tension, the sliding between the first friction plate 36 and the second friction plate 37 stops, and the rotating shaft 32 returns to normal operation. Therefore, each wind-up roller 28 can continuously work for a long time, frequent replacement of the wind-up roller 28 is avoided, the use efficiency of the wind-up roller 28 is improved, and the production efficiency of the steel wire is further improved.

In this embodiment, a top plate 38 is further slidably disposed on the rotating shaft 32, and the top plate 38 abuts against the second sleeve 35. The tail end of the rotating shaft 32 is connected with an adjusting nut 40 in a threaded manner, the rotating shaft 32 is sleeved with a spring 39, and two ends of the spring 39 respectively prop against the adjusting nut 40 and the top plate 38. The deformation of the spring 39 is adjusted through the knob adjusting nut 40, so that the friction force between the first friction plate 36 and the second friction plate 37 is adjusted, and finally, the rotation moment of the steel wire winding disc 3 is adjusted. When the rotation moment of the steel wire winding disc 3 is different, the linear speed of the outer circumferential surface of the steel wire winding on the winding roller 28 is also different when the first friction plate 36 and the second friction plate 37 slide relatively, and according to the winding condition of the steel wire winding, the nut 40 is adjusted by turning to realize the adjustment of the rotation moment, and finally, the adjustment of the winding speed of the steel wire is realized. And it will be readily appreciated that wear will occur between the first friction plate 36 and the second friction plate 37, and that the second friction plate 37 will be forced to engage the first friction plate 36 all the time by the spring 39 against the second friction plate 37.

The abrasive wire removing mechanism 5 comprises a scraping piece 41, a supporting piece 42 and a scraping driving assembly, and the scraping driving assembly is arranged on the frame 1. And the scraping member 41 and the supporting member 42 are disposed on the fixing frame 24, and the scraping member 41 is located above the supporting member 42. The scraping driving component is connected with the scraping piece 41 and is used for driving the scraping piece 41 to move close to or away from the supporting piece 42.

Specifically, in the present embodiment, as shown in fig. 3 and 4, the scraping member 41 includes a sliding seat 43 and a scraper 44, and the scraper 44 is mounted on the sliding seat 43. As a specific installation mode, a slotting tool groove 50 penetrating through the upper end face and the lower end face of the sliding seat 43 is formed in the bottom end face of the sliding seat 43, the scraper 44 is inserted into the slotting tool groove 50, two rows of through holes are formed in the sliding seat 43 and are respectively formed in two sides of the slotting tool groove 50, screws are inserted into the through holes, the sliding seat 43 and the sliding block 49 are kept relatively fixed through the screws, the screws are abutted against the outer wall of the scraper 44 in the slotting tool groove 50, and the scraper 44 and the sliding seat 43 are kept relatively fixed through friction.

The scraping driving component is a scraping driving air cylinder 45, and the scraping driving air cylinder 45 is vertically arranged on the frame 1. The scraping driving cylinder 45 and the scraping member 41 are located at two opposite sides of the fixing frame 24 to avoid interference of the scraping driving cylinder 45 to steel strip feeding. The fixing frame 24 is vertically provided with a sliding through groove 46, a sliding plate 47 is slidably arranged in the sliding through groove 46, and two ends of the sliding plate 47 are respectively connected with the scraping driving cylinder 45 and the sliding seat 43.

Further, a guide rail 48 extending along the vertical direction is provided on the fixing frame 24, a sliding block 49 is slidably provided on the guide rail 48, and the sliding block 49 is fixedly connected with the sliding seat 43. The guide rail 48 and the sliding block 49 avoid surface abrasion during sliding of the sliding seat 43, and also play a role in limiting and guiding the sliding seat 43.

The scraping driving cylinder 45 is driven, the sliding seat 43 and the scraper 44 are lifted, a section of the manually restored steel belt is placed on the supporting piece 42 and inserted into the subsequent steel belt reduction mechanism 6, and the steel belt reduction mechanism 6 drives the steel belt to feed. At this time, the scraping driving cylinder 45 drives the sliding seat 43 and the scraper 44 to descend, so that only a gap capable of passing through the steel belt is left between the tip of the scraper 44 and the supporting member 42 to form the belt feeding channel 21. By first placing a manually recovered length of steel strip on the support 42 and then depressing the doctor blade 44, the steel strip is restrained by the subsequent strip reduction mechanism 6, and no skew or deviation of the steel strip occurs when entering the feed channel 21. When the subsequent steel belt enters the belt feeding channel 21, abrasive wires on the steel belt are blocked by the scraper 44 and separated from the steel belt, so that the abrasive wires are removed, and the abrasive wires are prevented from entering the subsequent steel belt reduction mechanism 6.

The through-belt has a belt inlet and a belt outlet. The strip enters through the entrance and exits from the exit away from the doctor blade 44. As shown in fig. 23 and 24, the doctor blade 44 includes a cutter head 51 and a blade body 52, the cutter head 51 has a material abutment surface 53, the material abutment surface 53 is opposite to the tape inlet, and when the steel tape passes through the tape inlet channel 21, the abrasive wire abuts against the material abutment surface 53 and is separated from the steel tape. In the present embodiment, the abutment surface 53 is gradually inclined toward the inside of the doctor blade 44 from the cutter head 51 to the blade 52. When the abrasive wire collides with the material supporting surface 53, the abrasive wire moves upwards along the material supporting surface 53 for a certain distance, so that the abrasive wire is conveniently separated from the steel belt.

Meanwhile, the side surface of the cutter head 51 opposite to the material supporting surface 53 is gradually inclined towards the inside of the scraper 44 from the cutter body 52 to the cutter tip direction, so that the area of the bottom end surface of the cutter head 51 is reduced, and the contact area between the cutter head 51 and the steel belt is reduced and the abrasion between the steel belt and the cutter head 51 is reduced due to the reduction of the area of the bottom end surface of the cutter head 51. And because tool bit 51 contacts with the steel band, the tool bit 51 takes place wearing and tearing after long-time work, only need dismantle the screw at this moment can accomplish the change of tool bit 51, convenient and fast.

In this embodiment, the width of the material supporting surface 53 gradually increases from the tip of the cutter head 51 to the cutter body 52, and is in an inverted trapezoid shape. When the steel belt on the supporting piece 42 passes through the belt passage, the cutter head 51 of the scraper 44 presses the flanges on the two sides of the steel belt on the supporting piece 42 to turn outwards, a certain pre-expansion function is achieved, and breakage caused by overlarge one-time rotation angle of the flange of the steel belt after the steel belt with the flange directly enters the steel belt reduction mechanism 6 is avoided.

In this embodiment, the supporting member 42 is a supporting wheel, and the supporting wheel is rotatably disposed on the fixing frame 24. And the supporting wheel is provided with a avoiding groove 54 which can pass through the steel belt along the circumferential direction. The friction between the supporting wheels and the steel belt is converted into rolling friction through the fact that the supporting wheels can rotate, so that friction between the supporting wheels and the steel belt is reduced, and abrasion of the steel belt is reduced. And the steel belt is limited and guided through the avoiding groove 54, so that the steel belt is prevented from being inclined.

In addition, the frame 1 is further provided with a storage box 55 for receiving abrasive wires, and the storage box 55 is positioned below the supporting member 42. The abrasive wire removed via the abrasive wire removal mechanism 5 is received by the magazine 55 for subsequent recovery processing. In this embodiment, the guiding filter 22 is also located above the storage tank 55, and the abrasive wires filtered through the filter holes 23 also fall into the storage tank 55 to be collected and recycled.

Referring to fig. 12-19, the steel strip reduction mechanism 6 includes a base 56, the base 56 being mounted on the frame 1. The base 56 is provided with a plurality of pairs of steel strip reduction wheel sets 57 which are sequentially arranged along the conveying direction of the steel strip, and each pair of steel strip reduction wheel sets 57 comprises a first shaping wheel 58 and a second shaping wheel 60 which are matched with each other. Wherein, the wheel wall of the first shaping wheel 58 is provided with a convex rib 59 along the circumferential direction, and the wheel wall of the second shaping wheel 60 is provided with a shaping groove 61 matched with the convex rib 59 along the circumferential direction. A trimming channel 62 which can pass through the steel belt is formed between the convex ridge 59 and the shaping groove 61 in the steel belt reduction wheel set 57. Referring to fig. 13 to 15, the width of the ridge 59 on the adjacent two first forming wheels 58 increases in the steel strip conveying direction, and the height of the ridge 59 on the adjacent two first forming wheels 58 decreases in the steel strip conveying direction. In this embodiment, the number of the steel strip reduction wheel groups 57 is three, but four pairs, five pairs, and five or more pairs may be used to ensure that the steel strip can be reduced by extrusion.

The steel belt reduction mechanism 6 further includes a steel belt drive assembly including a steel belt drive motor 97. As shown in fig. 18 and 19, each second shaping wheel 60 is coaxially provided with a first transmission shaft 63, each first transmission shaft 63 is coaxially provided with a first transmission gear 64, a second transmission shaft 65 is arranged between two adjacent first transmission shafts 63, the second transmission shaft 65 is rotatably connected with the base 56, the second transmission shaft 65 is coaxially provided with a second transmission gear 66, and the second transmission gear 66 is meshed with the first transmission gears 64 on the first transmission shafts 63 on two adjacent sides. In this embodiment, the steel belt driving motor 97 is connected to one of the first transmission shafts 63, but it is also possible that the steel belt driving motor 97 is connected to the other first transmission shaft 63 or the second transmission shaft 65.

The steel strip from which the abrasive wire is removed by the above-described abrasive wire removing mechanism 5 is inserted into the strip repairing passage 62 in the first group of the steel strip reducing wheel groups 57. The steel belt driving motor 97 drives the connected first transmission shaft 63 to connect, and the first transmission shaft 63 drives the coaxial first transmission gear 64 to rotate when rotating. In the process of rotating the first transmission gear 64, as the first transmission gear 64 is meshed with the adjacent second transmission gear 66, the first transmission gear 64 drives the second transmission gear 66, and the second transmission gear 66 drives the first transmission gear 64 on the other side to rotate, so that synchronous rotation of a plurality of first transmission shafts 63 is realized, and the second shaping wheels 60 on each first transmission shaft 63 can synchronously rotate. When the second shaping wheel 60 rotates, the steel belt is driven to feed by friction force, and sequentially passes through the belt repairing channels 62 in the steel belt reduction wheel groups 57 arranged along the conveying direction. The second shaping wheels 60 on each first transmission shaft 63 can synchronously rotate, so that the conveying speeds of the steel belts in the steel belt reduction wheel sets 57 are kept consistent, and the problem of unsmooth feeding caused by inconsistent conveying speeds of the steel belts is avoided.

When the steel belt is inserted into the belt repairing channel 62 in the first pair of steel belt reduction wheel sets 57, the steel belt driving motor 97 drives the second shaping wheel 60 to rotate, the second shaping wheel 60 drives the steel belt to feed, and the first shaping wheel 58 and the second shaping wheel 60 are driven to synchronously and reversely rotate by friction force between the first shaping wheel 58 and the steel belt. Meanwhile, the raised edges 59 of the first shaping wheel 58 are matched with the shaping grooves 61 on the second shaping wheel 60 to press the flanging of the steel belt to turn outwards for extrusion reduction, in the extrusion reduction process, the raised edges 59 and the shaping grooves 61 are respectively contacted with the upper belt surface and the lower belt surface of the steel belt, the steel belt is driven to advance to the next pair of steel belt reduction wheel sets 57 through friction force to perform extrusion flanging again until the steel belt passes through all the steel belt reduction wheel sets 57 to finish reduction actions. Since the heights of the ribs 59 on the two adjacent first forming wheels 58 are sequentially reduced along the conveying direction of the steel belt, the ribs 59 of the first forming wheels 58 press the flanging of the steel belt to gradually turn outwards until the flanging is flat, and the steel belt is gradually flattened through the plurality of pairs of steel belt reduction wheel sets 57, so that the steel belt is prevented from being broken due to one-time flattening. After the steel belt finishes the reduction action through all the steel belt reduction wheel sets 57, the belt surface of the steel belt is flat, so that the subsequent recycling is convenient.

In this scheme, as shown in fig. 4, the steel belt driving motor 97 and the winding driving motor 96 are the same motor, the motor is mounted on the frame 1, the output shaft of the motor is connected with a speed reducer 95, and a first driving gear 67 is coaxially arranged on a connecting shaft of the speed reducer 95 connected with the first transmission shaft 63. The second driving gear 68 is arranged on the rotating shaft 32 in the steel wire recovery mechanism 94, the first driving gear 67 is in transmission connection with the second driving gear 68 through a transmission chain, and further synchronous rotation of the second shaping wheel 60 and the steel wire winding disc 3 is achieved, so that the steel belt and the steel wire can be fed simultaneously. However, it is easy to understand that, in the case of ensuring that the steel belt and the steel wire are fed simultaneously, it is also possible to adopt two different motors as the steel belt driving motor 97 and the winding driving motor 96, wherein the steel belt driving motor 97 is directly connected with the first transmission shaft 63, and the winding driving motor 96 is directly connected with the rotation shaft 32.

And in this embodiment the diameter of the first drive gear 67 is smaller than the diameter of the second drive gear 68. Since the steel wire needs to be firstly pulled out from the steel belt in the recycling process, the steel belt can enter the abrasive wire removing mechanism 5 to remove the abrasive and then enter the steel belt reducing mechanism 6. Therefore, the steel wire extraction speed must be faster than the steel belt feeding speed, the diameter of the first driving gear 67 is smaller than the diameter of the second driving gear 68, and the rotation speed of the rotation shaft 32 is faster than the rotation speed of the first transmission shaft 63 at the same motor rotation speed, so that the steel wire extraction speed is faster than the steel belt feeding speed, and the steel wire is prevented from affecting the steel belt conveying.

The top end of the base 56 is further provided with a plurality of lifting cylinders 69, each lifting cylinder 69 is connected with one first forming wheel 58, and specifically, the first forming wheel 58 is rotatably connected with the push rod of the corresponding lifting cylinder 69. The lifting cylinder 69 is used for driving the first shaping wheel 58 to move towards or away from the second shaping wheel 60 in the same steel belt reduction wheel set 57 along the vertical direction. It is easy to understand that when the flange 59 of the first shaping wheel 58 is matched with the shaping groove 61 on the second shaping wheel 60 to press the flanging of the steel belt to turn outwards for extrusion reduction, friction exists between the steel belt and the flange 59, and after the first shaping wheel 58 rotates for a long time, the contact surface between the flange 59 and the steel belt has certain abrasion. After the ribs 59 are worn, the height of the belt repairing channel 62 formed between the ribs 59 and the shaping groove 61 is changed, and the worn ribs 59 cannot press the turned edges of the subsequent steel belt to turn outwards to squeeze and restore. At this time, the lifting cylinder 69 pushes the first shaping wheel 58 to descend to be close to the second shaping wheel 60, so that the height of the repairing belt 62 is kept unchanged all the time, the worn flange 59 can still press the flanging of the subsequent steel belt to outwards overturn for extrusion reduction, the first shaping wheel 58 does not need to be replaced on a horse, the utilization rate of the first shaping wheel 58 is improved, and consumables are saved. And it is easy to understand, and to the steel band of different thickness, repair the height that takes passageway 62 also needs to be adjusted, drive first setting wheel 58 through the cylinder and rise or descend, just can realize repairing the height adjustment that takes passageway 62 for this mechanism is applicable to the steel band of different thickness.

Referring to fig. 17-19, the base 56 is further provided with a guiding block 70, and the guiding block 70 is located in front of the pairs of steel strip reduction wheel sets 57 along the conveying direction of the steel strips. The guiding block 70 is provided with guiding grooves 71 for penetrating through the steel belt, one ends of the grooves at two ends of the guiding grooves 71 are aligned with the belt passing channels in the abrasive wire removing mechanism 5, and the other ends of the grooves are aligned with the belt repairing channels 62 in the steel belt reducing wheel set 57 at the head end. The guiding and limiting are carried out on the steel belt through the guiding blocks 70, so that the steel belt is prevented from being offset with the convex edges 59 or the outer wall of the first shaping wheel 58 or the outer wall of the second shaping wheel 60 when the abrasive wire removing mechanism 5 enters the steel belt reduction wheel set 57 positioned at the head end. In this embodiment, the groove width of the guiding groove 71 is the same as the groove width of the shaping groove 61 on the second shaping wheel 60 in the steel strip reduction wheel set 57 at the head end, and the height of the guiding groove 71 is the same as the depth of the shaping groove 61 on the second shaping wheel 60 in the steel strip reduction wheel set 57 at the head end. So that the steel belt will not move laterally when entering the steel belt reduction wheel set 57 at the head end from the guide block 70, and the conveying process is more stable.

A guide block 72 is further arranged between two adjacent steel belt reduction wheel sets 57, a guide groove 73 for penetrating through the steel belt is arranged on the guide block 72, the guide groove 73 penetrates through the front end and the rear end of the guide block 72, and notches at two ends of the guide groove 73 are aligned with the belt repairing channels 62 in the two adjacent steel belt reduction wheel sets 57 respectively. The steel strip is guided by the guide grooves 73 to avoid deviation of the steel strip. And the groove width of the guide groove 73 on the guide block 72 is the same as the groove width of the shaping groove 61 on the second shaping wheel 60 located at the front end of the guide block 72 in the steel belt conveying direction, and the height of the guide groove 73 on the guide block 72 is the same as the depth of the shaping groove 61 on the second shaping wheel 60 located at the front end of the guide block 72 in the steel belt conveying direction. Since the sizes of the trimming channels 62 in each of the steel strip reduction wheel sets 57 are different, the width and height of the guide groove 73 are consistent with those of the shaping groove 61 on the previous second shaping wheel 60, so that the steel strip is more stable and does not shake in the conveying process.

In this embodiment, the guide block 72 is provided with first arc surfaces adapted to the outer wheel walls of the two adjacent first shaping wheels 58 on both front and rear sides of the upper end surface, and the guide block 72 is provided with second arc surfaces adapted to the outer wheel walls of the two adjacent second shaping wheels 60 on both front and rear sides of the lower end surface. So that the guide block 72 can be closer to the first shaping wheel 58 and the second shaping wheel 60, and interference between the guide block 72 and the first shaping wheel 58 and the second shaping wheel 60 is avoided. Similarly, the above-mentioned approach blocks are also curved surfaces on both front and rear sides of the upper and lower end surfaces, which are adapted to the steel belt reduction wheel set 57 and the support wheels in the abrasive wire removing mechanism 5 at the head end.

The base 56 is further provided with a guiding block 74, the guiding block 74 is located at the rear of the pairs of steel belt reduction wheel sets 57 along the conveying direction of the steel belt, the guiding block 74 is provided with a guiding groove 75 for passing through the steel belt, and the notch of the guiding groove 75 is aligned with the repairing channel 62 in the steel belt reduction wheel set 57 located at the tail end. The steel belt is guided and limited, so that the steel belt cannot naturally droop, the steel belt conveyed at the back is prevented from being pulled to prevent the steel belt from being flattened, and the steel belt can be orderly matched with a subsequent mechanism to cut. And the groove width of the guiding groove 75 is the same as the groove width of the shaping groove 61 on the second shaping wheel 60 in the steel belt reduction wheel set 57 at the tail end, and the height of the guiding groove 75 is the same as the depth of the shaping groove 61 on the second shaping wheel 60 in the steel belt reduction wheel set 57 at the tail end.

Referring to fig. 20-22, the steel strip recycling apparatus further includes a steel strip cutting mechanism 7, the steel strip cutting mechanism 7 including a mounting block 76 and a controller. The mounting seat 76 is arranged at the tail end of the frame 1, and a steel belt outlet for passing through the steel belt is arranged on the mounting seat 76. The steel strip outlet is aligned with the notch of the guide groove 75 of the guide block 74, and the size of the steel strip outlet is the same as the notch of the guide groove 75. And the mounting seat 76 is also provided with a receiving hopper 77, a cutting driving assembly and a cutter 79. The receiving hopper 77 is provided with a detecting member 91, and when the steel strip passing through the steel strip outlet extends to a detecting position, the detecting member 91 sends out a detecting signal. The controller is used for receiving the detection signal of the detection piece 91 and controlling the action of the cutting driving assembly. The cutter 79 is connected with a cutting driving assembly, and when the controller receives the detection signal, the controller controls the cutting driving assembly to drive the cutter 79 to move perpendicular to the conveying direction of the steel strip so as to cut off the steel strip at the outlet of the steel strip, and the receiving hopper 77 receives the cut-off steel strip.

The cutting drive assembly drives the cutters 79 to cut the steel strips, so that subsequent stacking and storage are facilitated, each steel strip only extends to a designated position to trigger the detection part 91, and the cutting drive assembly only drives the cutters 79 to cut when the detection part 91 receives a detection signal, so that the consistency of the lengths of the cut steel strips of each section can be ensured, and subsequent recycling is facilitated.

In one embodiment, the cutting drive assembly includes a cutter drive cylinder 78, and the cylinder of the cutter drive cylinder 78 is hinged to the mounting base 76. The head end of the cutter 79 is hinged with the mounting seat 76, and the tail end of the cutter 79 is connected with a push rod of the cutter driving cylinder 78. When the controller receives the detection signal, the air cylinder drives the pushing bar to stretch and retract so as to drive the cutter 79 to rotate around the hinge point of the cutter 79 and the mounting seat 76 to cut off the steel belt at the outlet of the steel belt.

In this embodiment, the two sides of the cutter 79 are provided with blades, and the blades are divided into an upper blade and a lower blade. The cutter driving cylinder 78 sequentially drives the cutter 79 to rotate clockwise around the hinge point of the cutter 79 and the mounting seat 76 according to the detection signal, the lower cutting edge cuts off the steel belt at the outlet of the steel belt, or drives the cutter 79 to rotate anticlockwise around the hinge point of the cutter 79 and the mounting seat 76, and the upper cutting edge cuts off the steel belt at the outlet of the steel belt. If the cutter 79 only has a blade on one side, the cutter 79 needs to be driven to reset after the steel strip is cut by the cutter 79 each time, and the next cutting can be performed, so that the time consumption of a single process is long. And because both sides of cutter 79 all have the cutting edge, the both sides of cutter 79 all can realize cutting the steel band, do not need to drive cutter 79 again to reset after driving cutter 79 to cut the steel band at every turn, and the cutter 79 reverse feeding can be realized cutting when cutting next time, has reduced the process time consuming, has improved cutting efficiency. By way of example only, when the steel strip triggers the detector 91, the cutter driving cylinder 78 drives the cutter 79 to rotate clockwise about the hinge point of the cutter 79 and the mounting base 76, and the lower blade cuts off the steel strip at the steel strip outlet, the cutter 79 stays below the steel strip outlet. When the next section of steel strip triggers the detecting member 91, the cutter driving cylinder 78 drives the cutter 79 to rotate anticlockwise around the hinge point of the cutter 79 and the mounting seat 76, and after the upper blade cuts off the steel strip at the outlet of the steel strip, the cutter 79 stays at the position above the outlet of the steel strip, and sequentially circulates.

And in order to avoid interference of the cutter 79 with the receiving hopper 77. The mounting block 80 is mounted on the mounting seat 76, and the mounting block 80 is provided with a tape outlet channel 81 penetrating through opposite ends of the mounting block 80, and the tape outlet channel 81 is aligned with the steel strip outlet. And two connecting plates 82 are connected to the mounting block 80, each connecting plate 82 is connected with a partition plate 83, and an included angle is formed between each partition plate 83 and each connecting plate 82 to form an L-shaped structure. The plate surfaces of the partition plates 83 are opposite to the steel belt outlet, the two partition plates 83 are respectively arranged at two sides of the belt outlet channel 81, and a gap capable of passing through the steel belt is reserved between the two partition plates 83. And a cutting channel 84 is formed between the partition 83 and the mounting block 80, and the cutter 79 moves in the cutting channel 84 under the action of the driving assembly to cut off the steel belt passing through the belt outlet channel 81. The receiving hopper 77 is mounted on the two partition plates 83, and a feeding port is formed in the receiving hopper 77 and is communicated with a gap between the two partition plates 83.

In this embodiment, the mounting block 80 is detachably connected to the connecting plate 82. The connection plate 82 may be removed to replace the cutting blade 79 as the cutting blade 79 wears. In a preferred embodiment, the mounting block 80 is provided with a screw hole, the connecting plate 82 is provided with an adjustment through groove 85 extending along the length direction of the receiving hopper 77, and a screw rod is inserted into the adjustment through groove 85. When the connecting plate 82 and the partition plate 83 move to the state that the plate surface of the partition plate 83 is attached to the cutter surface of the cutter 79, a screw penetrates through the through groove and is in threaded connection with the threaded hole, a nut is sleeved on the screw, and the nut presses the connecting plate 82 and the mounting block 80 to be relatively fixed. Because the cutter 79 is in the in-process of cutting, the face of the cutter 79 will rub against the mounting block 80 and the partition 83, resulting in the thickness thinning of the cutter 79, the connecting plate 82 can move away from or close to the mounting block 80 by adjusting the through groove 85, so that the width of the cutting channel 84 is always matched with the thickness of the cutter 79, and the cutter 79 is prevented from shaking in the cutting process.

Specifically, the pivotal plate 87 is provided with a hinge shaft 88 extending in the longitudinal direction thereof, and the hinge shaft 88 is inserted into the coupled partition 83 so that the head end of the pivotal plate 87 is rotatably coupled to the corresponding partition 83. The feed inlet is formed between the head end of the fixed plate 86 and the head end of the rotating plate 87, and both the fixed plate 86 and the rotating plate 87 extend along the direction of horizontally facing away from the tape outlet.

Meanwhile, a balancing weight 89 is arranged on the outer side of the top of the rotating plate 87, and the balancing weight 89 drives the rotating plate 87 to rotate under the action of self gravity until the bottom of the rotating plate 87 abuts against the plate surface of the fixed plate 86. With the continuous feeding of the steel strip, the steel strip is cut segment by the cutter 79, and the cut steel strip falls into the receiving hopper 77 for collection. When the steel strips in the receiving hopper 77 are stacked to a preset quantity, the weight of the steel strips is larger than that of the balancing weights 89, the steel strips press the rotating plate 87 to rotate, so that the bottom of the rotating plate 87 is far away from the fixed plate 86 to form a discharging opening of the accessible steel strips, the steel strips in the receiving hopper 77 are discharged through the discharging opening to be collected, the quantity of the steel strips discharged each time is the same, and the step of sub-packaging the subsequent steel strips is saved. After the steel belt is fed, the bottom of the rotating plate 87 loses acting force, and the balancing weight 89 drives the bottom of the rotating plate 87 to rotate again until the bottom of the rotating plate 87 abuts against the plate surface of the fixed plate 86 to bear the steel belt for the next circulation.

As shown in fig. 22, the receiving hopper 77 further includes a hinge 100 and an elastic member. One side of the hinge 100 is hinged to the tail end of the fixed plate 86, and the other side of the hinge 100 abuts against the tail end of the rotating plate 87. In this embodiment, the hinge 100 is connected to the inner surface of the fixing plate 86 by an elastic member. The detecting member 91 is a travel switch, the travel switch is disposed on the fixing plate 86, when the hinge 100 rotates relative to the fixing plate 86, the hinge 100 triggers the travel switch, the travel switch sends a detection signal, and the controller controls the cutter driving cylinder 78 to drive the cutter 79 to cut the steel belt. And the elastic member is deformed during the rotation of the hinge 100, and in this embodiment, the elastic member is a tension spring 90. When the cutter 79 cuts off the steel belt at the outlet of the steel belt, the hinge 100 loses the acting force of the steel belt, and the tension spring 90 drives the hinge 100 to reset. In this embodiment, when the steel strip lifting hinge 100 rotates relative to the fixing plate 86, the cutter 79 cuts off the steel strip at the outlet of the steel strip under the action of the cutting driving assembly, so that the length of the steel strip of each section is kept consistent. And because the head end of the steel belt is propped against the hinge 100, the tail end of the steel belt is limited by the steel belt reduction mechanism 6, and the two ends of the steel belt are stressed, so that the steel belt is in a straightened state, and the cutting of the cutter 79 is facilitated. Meanwhile, the hinge 100 can be automatically reset through the elastic piece.

And to avoid bending of the strip itself during lifting of the hinge 100. Referring to fig. 15, the bottoms of the shaping grooves 61 on the second shaping wheel 60 in the last pair of the steel strip reduction mechanism 6 are arc surfaces recessed inward. The cross section of the corresponding convex ridge 59 on the first shaping wheel 58 is an arc-shaped bulge. Therefore, the strip surface of the steel strip coming out of the last pair of steel strip reduction wheel sets 57 is not completely flat, but is slightly in a certain arc shape, so that the steel strip entering the steel strip cutting mechanism 7 is in an arc-shaped special-shaped part, the structural strength of the steel strip is improved, and the problem that the hinge 100 cannot trigger a travel switch due to the fact that the steel strip bends to push up the hinge 100 after striking the hinge 100 is avoided.

In addition, as shown in fig. 20, an oil inlet rod 92 is further disposed on the partition 83, an oil inlet channel is disposed on the oil inlet rod 92 along the length direction thereof, and an oil hole 93 is disposed on the oil inlet rod 92, and the oil hole 93 is connected with the oil inlet channel. Meanwhile, the partition 83 is provided with a through hole, through which the oil feed passage communicates with the cutting passage 84. Oil is supplied through the oil hole 93, and enters the cutting passage 84 along the oil supply passage, thereby lubricating the cutter 79. The invention and its embodiments have been described above by way of illustration and not limitation, and the invention is illustrated in the accompanying drawings and described in the drawings in which the actual structure is not limited thereto. Therefore, if one of ordinary skill in the art is informed by this disclosure, the structural mode and the embodiments similar to the technical scheme are not creatively designed without departing from the gist of the present invention.
