Description

Steel band recovery unit

Technical Field

The invention relates to the technical field of steel belt recovery, in particular to a steel belt recovery device.

Background

The flat steel strip is applied to many fields, generally is a hot-rolled steel plate, and the surface of the flat steel strip is inevitable to generate stain and rust and the like during production, so the stain and rust on the surface of the flat steel strip need to be treated before the flat steel strip is used so as to meet the production requirement, and the same is true of a steel wire.

The conventional treatment of flat steel strip or wire stock is mainly to remove rust and some contaminants from the surface. The current general treatment method adopts a chemical treatment method. The surface rust and some pollutants of the flat steel strip are removed by using an acidic liquid. Such treatment methods have the following disadvantages: the flat steel strip is treated by adopting the chemical acidic liquid, and finally, more acidic waste liquid is generated, so that the environment is polluted and is not environment-friendly.

The document with the application number of '201921666907.6' proposes that a brush strip is formed by planting abrasive wires on a steel belt, the brush strip is wound at two ends of the surface of a phosphorus breaking roller to be fixed, and rust removal is realized by winding the abrasive wires on the phosphorus breaking roller to brush a flat steel belt or a steel wire. After the phosphorus-breaking roller works for a period of time, the abrasive wires on the surface are worn and the rust cannot be removed continuously. Just need be with the brush strip rolling on putting the reel in order to save the consumptive material to unreel the brush strip and lead into among the recovery unit and get rid of the abrasive material silk and retrieve the steel band. In order to facilitate the storage of the steel belt, a cutting mechanism such as a cutter can be adopted to cut the steel belt in sections. In order to keep the length of each steel strip after the steel strip is segmented relatively consistent, a detection piece such as a travel switch is usually adopted to measure and position the length of the steel strip so as to cooperate with a cutting mechanism to perform segmented cutting. If the steel belt is directly cut, the head end of the steel belt is not stressed, and the steel belt may bend and move along with the feeding of the cutter in the cutting process, so that the cutting cannot be realized. Only when the limiting part is arranged on the travel path of the steel belt, the steel belt pushes the limiting part and triggers the detection parts such as the travel switch, and the limiting part provides a limiting acting force to the head end of the steel belt, and the cutting can be better realized through the stress at the two ends of the steel belt. However, because the steel belt has certain flexibility, after the flat steel belt abuts against the limiting part positioned on the travel path of the steel belt, the problem that the steel belt can be bent to lift the limiting part to trigger the travel switch exists; in the prior art, 2-3 wheels are generally arranged for leveling the steel belt and are respectively driven, so that the synchronization cannot be guaranteed, the rotating speeds of the wheels are difficult to keep consistent, the leveling effect is poor, or the leveling effect of the steel belt is inconsistent, the trouble is brought to cutting, and the cutting edges are uneven.

Detailed Description

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

In the description of the present invention, it is to 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 those shown in the drawings, and are only for convenience of description and simplicity of description, and do not indicate or imply that the referenced devices or elements must have a particular orientation, be constructed and operated in a particular orientation, and thus, are not to be construed as limiting the present invention.

Referring to fig. 1 to 24, the present embodiment provides a steel strip recycling apparatus, which is a component of a brush bar recycling apparatus, and the brush bar recycling apparatus will be described in detail below.

The utility model provides a brush strip recovery plant, includes frame 1, and frame 1 has head end and tail end along self length direction, and the head end of frame 1 is provided with brush strip unreels 2 and steel wire rolling dish 3, and brush strip unreels 2 and steel wire rolling dish 3 all can rotate for frame 1, wherein the brush strip that remains to be handled around rolling up on brush strip unreeling 2.

The frame 1 is sequentially provided with a brush bar guide mechanism 4, a grinding wire removing mechanism 5 and a steel belt reducing mechanism 6 along the conveying direction of the steel belt. As shown in fig. 8-11, the brush bar guiding mechanism 4 includes a fixing block 8, a rotating shaft 9, a connecting rod 10, a guiding rod 11, a limiting plate 12, and a limiting component 13. Fixed block 8 fixed mounting is in frame 1, and limiting plate 12 fixed mounting is on fixed block 8, and pivot 9 is rotatable to be set up on 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 vertical 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 respectively vertical to the extending direction of the connecting rod 10 and the rotating shaft 9. The limiting assembly 13 acts on the rotating 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 the brush bar is formed between the guide bar 11 and the limit plate 12.

It is easy to understand that when the lengths of the wound brush bars are different, the diameters of the brush bar rolls are different after the brush bars are wound on the winding disc, and the different diameters of the brush bar rolls can cause the brush bars to enter the abrasive wire removing mechanism 5 at different heights for wire removal. 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 get into abrasive material silk via the feed channel 14 that forms between guide bar 11 and the limiting plate 12 all the time and get into abrasive material silk and get rid of mechanism 5, carries on spacingly through guide bar 11 and limiting plate 12 to the left and right sides of brush strip, avoids the brush strip to rock in transportation process and influences subsequent abrasive material silk and go a silk and the steel band reduction. In addition, in the unreeling process of 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 unreeling process of the brush strip due to the fact that the guide rod 11 has a certain length.

And in order to avoid the abrasion of the brush strip caused by the friction between the guide rod 11 and the side wall of the brush strip, 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 15 relative to the guide rod 11. At the in-process that the brush strip was carried, the brush strip offsets with rotary drum 15 outer wall, turns into the rolling friction between brush strip and rotary drum 15 through rotary drum 15 with the frictional force between brush strip and the dead lever, has reduced frictional force, and then avoids the brush strip wearing and tearing.

In this scheme, as shown in fig. 8, limiting component 13 includes a limiting rod 16, an arc-shaped through groove 17 is formed in limiting plate 12 around rotating shaft 9, limiting rod 16 penetrates through arc-shaped through groove 17, and the head end of limiting rod 16 is connected with connecting rod 10. As a preferred embodiment, the position-limiting assembly 13 further comprises a connecting member 18, the connecting member 18 is disposed at the head end of the position-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 opposite fork plates, the connecting rod 10 penetrates through a fork groove formed between the two fork plates and is in clamping fit with the fork-shaped body 19, and then the head end of the limiting rod 16 is connected with the connecting rod 10. Meanwhile, the tail end of the limit rod 16 is in threaded connection with a limit nut 20. When the rotating shaft 9 drives the guide rod 11 to rotate relative to the fixing 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 specified position relative to the fixed block 8, the guide rod 11 and the limiting plate 12 can be kept relatively fixed only by screwing the limiting nut 20 to force the limiting nut 20 to be tightly attached 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 limiting rod 16 to slide in the arc-shaped through groove 17 when rotating, and the limiting rod 16 is stuck in the arc-shaped through groove 17. At this time, because the connecting rod 10 is in clamping fit with the fork-shaped body 19 on the connecting piece 18, the connecting piece 18 and the limiting rod 16 only need to be detached firstly, the connecting rod 10 and the guide rod 11 are rotated to the designated position, then the connecting piece 18 is inserted into the arc-shaped through groove 17, so that the connecting rod 10 penetrates through the fork groove again, and the limiting nut 20 at the tail end of the limiting rod 16 is screwed to complete the fixation.

It should be noted that, although the limiting rod 16 and the nut are used to cooperate with the arc-shaped through groove 17 to limit the position of the connecting rod 10 and the guiding rod 11 in this embodiment, other fixing manners in the prior art may also be used, for example, a plurality of through holes are provided on the limiting plate 12 around the axis of the rotating shaft 9, a bolt is provided on the connecting rod 10, and when the rotating shaft 9 drives the guiding rod 11 to rotate to an assigned position relative to the fixing block 8, the bolt is inserted into the corresponding through hole to fix the guiding rod.

It should be noted that, although in the present embodiment, the limiting component 13 acts on the connecting rod 10, it is also possible to use a scheme that 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, a bolt is arranged on the fixed block 8, and when the rotating shaft 9 drives the guide rod 11 to rotate to a specified position relative to the fixed block 8, the bolt is inserted into the corresponding through hole to achieve fixation.

Firstly, a section of steel belt at the head end of the brush bar is restored to be flat, and the steel wire on the steel belt is pulled away and passes through the filtering hole 23 to be wound on the steel wire winding disc 3. It is easy to understand, still can adhere to abrasive material silk on the steel wire of taking out on the brush strip and separating, the steel wire not only can influence the rolling effect if adulterating the same rolling of abrasive material silk, still can influence the subsequent use of steel wire. And when the steel wire passed filtration pore 23 and rewound to steel wire rolling dish 3 on, the steel wire is when the process filtration pore 23, and the abrasive material silk just has been got rid of by filtration pore 23 separation, has avoided avoiding the abrasive material silk to wind the problem that influences the rolling effect on steel wire rolling dish 3 along with the steel wire together.

In addition, in the present embodiment, the guiding filter 22 can slide up and down on the rack 1 along the vertical direction, and the limiting element acts on the guiding filter 22, so that when the guiding filter 22 slides to the designated position, the limiting element forces the guiding filter 22 to remain relatively fixed with the rack 1. To the brush strip book of different diameters size, the diameter size that the steel wire was rolled up behind the steel wire rolling dish 3 rolling steel wire is also just different, and to the steel wire book of different diameters size, in order to avoid the steel wire to pass and to take place to buckle by a wide margin on the steel wire rolling dish 3 of direction filtration pore 23 rolling, because guide filter piece 22 can follow vertical direction and slide from top to bottom on frame 1, can adjust guide filter piece 22's height according to the diameter size of steel wire book for the steel wire can not take place to buckle by a wide margin when passing direction filtration pore 23 rolling steel wire rolling dish 3.

The diameter of the wind-up roll 28 is gradually reduced from the second limit plate 30 to the first limit plate 29. Because the diameter of the winding roller 28 is gradually reduced from the second limit plate 30 to the first limit plate 29, after the steel wire is wound on the winding roller 28, a certain gap is formed between the steel wire coil and the winding 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 component, a supporting seat 31 and a rotating shaft 32, wherein the head end of the rack 1 is vertically provided with a stand column 33, and the supporting seat 31 is installed on the top end of the stand column 33.

Rolling drive assembly and supporting seat 31 all set up in frame 1, rotation axis 32 rotatable set up in on the supporting seat 31, rotation axis 32 with steel wire rolling dish 3 is connected, as shown in fig. 5 and 7, the cover has first sleeve 34 and second sleeve 35 on the rotation axis 32, first sleeve 34 and rotation axis 32 fixed connection, and second sleeve 35 is connected with rotation axis 32 circumferential direction, is provided with second friction disc 37 on the second sleeve 35, is provided with first friction disc 36 on the first sleeve 34, and first friction disc 36 laminates with second friction disc 37. The winding driving component is connected with the second sleeve 35 and used for driving the second sleeve 35 to rotate. When the second sleeve 35 rotates, the second friction plate 37 rotates therewith, the first friction plate 36 rotates together with the second friction plate 37 through the friction force between the first friction plate 36 and the second friction plate 37, the first friction plate 36 drives the first sleeve 34 and the rotating shaft 32 to rotate, and further drives the wire winding plate 3 to rotate. Specifically, the winding driving assembly in this scheme is a winding driving motor 96.

With the increase of the number of the steel wires wound by the winding roller 28, the overall diameter of the winding roller 28 is continuously increased, the linear speed (winding speed) of the outer peripheral surface thereof is also continuously increased, and the production speed of the steel wires is generally stable, so that the steel wires bear increasingly larger tension. When the static friction force between the first friction plate 36 and the second friction plate 37 cannot overcome the tension of the steel wire, a slip will occur between the first friction plate 36 and the second friction plate 37, so that the angular velocity of the wind-up roller 28 will be reduced, the linear velocity of the outer circumferential surface thereof will be reduced, and the tension borne by the steel wire will be reduced. When the tension applied to the wire is reduced to a certain level, the friction between the first friction plate 36 and the second friction plate 37 can be overcome, the sliding between the first friction plate 36 and the second friction plate 37 is stopped, and the rotating shaft 32 resumes normal operation. Therefore, each winding roller 28 can continuously work for a long time, frequent replacement of the winding roller is avoided, the use efficiency of the winding roller 28 is improved, and the production efficiency of steel wires is further improved.

In this embodiment, the rotating shaft 32 may further include a top plate 38, and the top plate 38 abuts against the second sleeve 35. The tail end of the rotating shaft 32 is in threaded connection with an adjusting nut 40, a spring 39 is sleeved on the rotating shaft 32, and two ends of the spring 39 are respectively abutted against the adjusting nut 40 and the top plate 38. The deformation amount of the spring 39 is adjusted by turning the 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 adjustment of the torque of the rotation of the wire winding disc 3 is realized. When the torque of the steel wire winding disc 3 is different, the linear velocity of the outer peripheral surface of the steel wire coil 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 coil, the nut 40 is turned to realize the adjustment of the rotating torque, and finally the adjustment of the steel wire winding speed is realized. It is easy to understand that the first friction plate 36 and the second friction plate 37 are worn, and the second friction plate 37 is always forced to be jointed with the first friction plate 36 by the spring 39 abutting against the second friction plate 37.

The abrasive filament removal mechanism 5 includes a scraping member 41, a carrier member 42, and a scraping drive assembly mounted to the frame 1. The scraping element 41 and the supporting element 42 are disposed on the fixing frame 24, and the scraping element 41 is disposed above the supporting element 42. And the scraping driving component is connected with the scraping member 41 and is used for driving the scraping member 41 to move close to or away from the supporting member 42.

Specifically, in the present embodiment, as shown in fig. 3 and 4, the scraper 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 manner, a knife slot 50 penetrating through the upper and lower end surfaces of the sliding seat 43 is arranged on the bottom end surface of the sliding seat 43, the scraper 44 is inserted into the knife slot 50, two rows of through holes are arranged on the sliding seat 43, the two rows of through holes are respectively arranged on two sides of the knife slot 50, a screw is inserted into each through hole, the sliding seat 43 and the sliding block 49 are kept relatively fixed through the screw, the screw abuts against the outer wall of the scraper 44 in the knife slot 50, and the scraper 44 and the sliding seat 43 are kept relatively fixed through friction force.

Scrape material drive assembly and drive actuating cylinder 45 for scraping the material, scrape the material and drive actuating cylinder 45 and vertically set up in frame 1. The scraping driving cylinder 45 and the scraping member 41 are positioned at two opposite sides of the fixed frame 24 to avoid the interference of the scraping driving cylinder 45 on the steel strip feeding. A sliding through groove 46 is vertically arranged on the fixed frame 24, 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.

Furthermore, the fixed frame 24 is provided with a guide rail 48 extending in the vertical direction, 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 prevent the sliding seat 43 from surface abrasion during sliding, and also play a role in limiting and guiding the sliding seat 43.

The cylinder 45 is driven by the forerunner driving scraping material, the sliding seat 43 and the scraper 44 are lifted, the manually recovered steel strip section is placed on the supporting piece 42 and inserted into the subsequent steel strip reduction mechanism 6, and the steel strip is driven by the steel strip reduction mechanism 6 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 through which the steel strip can pass is left between the cutting edge of the scraper 44 and the support 42 to form the strip feeding passage 21. By placing a section of manually restored steel strip on the supporting piece 42 and then pressing the scraper 44 downwards, the steel strip is limited by the subsequent steel strip reduction mechanism 6, and the steel strip cannot be skewed when entering the strip feeding channel 21. When the subsequent steel belt enters the belt feeding channel 21, the 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 tape passing channel is provided with a tape inlet and a tape outlet. The steel strip enters from the strip inlet and is far away from the scraper 44 from the strip outlet. As shown in fig. 23 and 24, the scraper 44 includes a cutter head 51 and a cutter body 52, the cutter head 51 has a material abutting surface 53, the material abutting surface 53 is opposite to the belt feeding port, and when the steel belt passes through the belt feeding passage 21, the abrasive filaments abut against the material abutting surface 53 and are separated from the steel belt. In the present embodiment, the material abutting surface 53 is gradually inclined toward the inside of the scraper 44 from the blade head 51 to the blade body 52. When the abrasive wire hits the material abutting surface 53, the abrasive wire moves upwards for a certain distance along the material abutting surface 53, 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 toward the inside of the scraper 44 from the cutter body 52 to the cutter point direction, so as to reduce the area of the bottom end surface of the cutter head 51, and since the area of the bottom end surface of the cutter head 51 is reduced, the contact area between the cutter head 51 and the steel belt is also reduced, and the abrasion between the steel belt and the cutter head 51 is reduced. Due to the fact that the cutter head 51 is in contact with the steel belt, the cutter head 51 is abraded after long-time work, the cutter head 51 can be replaced only by disassembling the screw, and the cutter head replacement is convenient and fast.

In the embodiment, the width of the material supporting surface 53 gradually increases from the cutting edge of the cutting head 51 to the blade 52, and is in an inverted trapezoid shape. When the steel belt on the supporting piece 42 passes through the belt passing channel, the cutter head 51 of the scraper 44 presses the two side flanges of the steel belt on the supporting piece 42 to turn outwards, so that a certain pre-expansion effect is achieved, and the phenomenon that the steel belt with the flanges is broken due to the fact that the steel belt flanges directly enter the steel belt reduction mechanism 6 and the steel belt flanges rotate for a time by too large angle 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 an avoiding groove 54 which can pass through the steel belt is arranged on the supporting wheel along the circumferential direction of the supporting wheel. The bearing wheel is rotatable, so that friction between the bearing wheel and the steel belt is changed into rolling friction, friction between the bearing wheel and the steel belt is reduced, and abrasion of the steel belt is reduced. And the steel belt is guided in a limiting way through the avoiding groove 54, so that the steel belt is prevented from being inclined.

In addition, a storage box 55 for receiving the abrasive filament is disposed on the frame 1, and the storage box 55 is located below the support 42. The abrasive filament removed by the abrasive filament removal mechanism 5 is received by the magazine 55 for subsequent recycling. In the present embodiment, the guiding filter 22 is also located above the storage box 55, and the abrasive filaments filtered by the filtering holes 23 also fall into the storage box 55 to be collected and recycled.

Referring to fig. 12 to 19, the steel strip reduction mechanism 6 includes a base 56, and the base 56 is 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 steel strip conveying direction, and each pair of steel strip reduction wheel sets 57 comprises a first sizing wheel 58 and a second sizing wheel 60 which are matched with each other. Wherein, be provided with the arris 59 along circumference on the wheel wall of first sizing wheel 58, be provided with the design recess 61 with arris 59 looks adaptation along circumference on the wheel wall of second sizing wheel 60. The convex edge 59 and the shaping groove 61 in the steel strip reduction wheel set 57 form a strip repairing channel 62 which can pass through the steel strip. Referring to fig. 13-15, the widths of the ridges 59 on two adjacent first shaping wheels 58 are sequentially increased along the steel belt conveying direction, and the heights of the ridges 59 on two adjacent first shaping wheels 58 are sequentially decreased along the steel belt conveying direction. Although the number of the steel strip reduction wheel sets 57 is three in the present embodiment, four, five, and five or more pairs may be used in the case of ensuring that the steel strips can be reduced by extrusion.

The steel strip reduction mechanism 6 further includes a steel strip driving assembly including a steel strip driving motor 97. As shown in fig. 18 and 19, a first transmission shaft 63 is coaxially arranged on each second sizing wheel 60, a first transmission gear 64 is coaxially arranged on each first transmission shaft 63, 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, a second transmission gear 66 is coaxially arranged on the second transmission shaft 65, 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 the steel belt driving motor 97 may be connected to the other of the first transmission shaft 63 and the second transmission shaft 65.

The steel belt from which the abrasive wire is removed by the abrasive wire removing mechanism 5 is inserted into the belt repairing channel 62 of the first steel belt reducing wheel set 57. The steel belt driving motor 97 drives the connected first transmission shaft 63 to be connected, 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, because 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 the plurality of first transmission shafts 63 is realized, and the second sizing wheel 60 on each first transmission shaft 63 can be ensured to synchronously rotate. When the second sizing wheel 60 rotates, the steel strip is driven to feed by friction, and the steel strip sequentially passes through the strip repairing channels 62 in the steel strip reduction wheel set 57 arranged along the conveying direction. And because the second sizing wheel 60 on each first transmission shaft 63 can synchronously rotate, 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 strip is inserted into the strip repairing channel 62 of the first pair of steel strip reduction wheel sets 57, the steel strip driving motor 97 drives the second shaping wheel 60 to rotate, the second shaping wheel 60 drives the steel strip to feed, and the first shaping wheel 58 and the second shaping wheel 60 are driven to synchronously rotate reversely by friction force between the first shaping wheel 58 and the steel strip. Meanwhile, the ridges 59 of the first sizing wheel 58 cooperate with the sizing grooves 61 on the second sizing wheel 60 to press the flanging of the steel strip to turn outwards for extrusion reduction, in the extrusion reduction process, the ridges 59 and the sizing grooves 61 are respectively in contact with the upper and lower strip surfaces of the steel strip, and the steel strip is driven by friction force to move forwards to the next pair of steel strip reduction wheel sets 57 for extrusion flanging again until the steel strip passes through all the steel strip reduction wheel sets 57 to complete reduction. Because the heights of the convex ridges 59 on the two adjacent first shaping wheels 58 are sequentially reduced along the conveying direction of the steel strip, the convex ridges 59 of the first shaping wheels 58 press the turned edges of the steel strip to gradually turn outwards until the turned edges are smooth, the steel strip is gradually flattened through the steel strip reducing wheel sets 57, and the steel strip is prevented from being broken due to one-time flattening. After the steel strip passes through all the steel strip reduction wheel sets 57 to complete reduction, the strip surface of the steel strip is relatively flat, and subsequent recycling is facilitated.

In the present embodiment, as shown in fig. 4, the steel belt driving motor 97 and the winding driving motor 96 are the same motor, the motor is installed on the frame 1, the output shaft of the motor is connected with the speed reducer 95, and the first driving gear 67 is coaxially arranged on the connecting shaft of the speed reducer 95 and the first transmission shaft 63. A second driving gear 68 is arranged on the rotating shaft 32 in the steel wire recovery mechanism 94, and the first driving gear 67 and the second driving gear 68 are in transmission chain connection, so that synchronous rotation of the second sizing wheel 60 and the steel wire winding disc 3 is realized, and the steel belt and the steel wires are kept fed simultaneously. However, it is easy to understand that, in the case of ensuring that the steel belt and the steel wire are simultaneously fed, it is also possible to adopt two different motors, namely, 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 rotating shaft 32.

And in this case the diameter of the first drive gear 67 is smaller than the diameter of the second drive gear 68. In the recycling process, the steel wire needs to be drawn out of the steel belt firstly, and 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 is extracted faster than the steel belt, and the diameter of the first driving gear 67 is smaller than that of the second driving gear 68, so that the rotating speed of the rotating shaft 32 is faster than that of the first transmission shaft 63 at the same motor speed, and the steel wire is prevented from affecting the steel belt.

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 shaping wheel 58, and specifically, the first shaping wheels 58 are rotatably connected with the push rods of the corresponding lifting cylinders 69. The lifting cylinder 69 is used for driving the first sizing wheel 58 to move towards or away from the second sizing wheel 60 in the super-same steel strip reduction wheel set 57 along the vertical direction. It is easy to understand that, the edge 59 of the first sizing wheel 58 cooperates with the sizing groove 61 on the second sizing wheel 60 to press the flanging of the steel belt to turn outwards for extrusion reduction, and meanwhile, friction exists between the steel belt and the edge 59, and after the first sizing wheel 58 rotates for a long time, the contact surface between the edge 59 and the steel belt has certain abrasion. After the convex edge 59 is worn, the height of the belt repairing channel 62 formed between the convex edge 59 and the shaping groove 61 changes, and the worn convex edge 59 cannot press the subsequent flanging of the steel belt to turn outwards for extrusion reduction. At the moment, 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 belt repairing channel 62 is kept unchanged all the time, the abraded convex edge 59 can still press the subsequent flanging of the steel belt to turn outwards to be extruded and restored, the first shaping wheel 58 does not need to be replaced immediately, the utilization rate of the first shaping wheel 58 is improved, and consumable materials are saved. And it is easy to understand, and to the steel band of different thickness, the height of repairing the band passageway 62 also need adjust, through cylinder drive first forming wheel 58 rise or descend, just can realize repairing the height adjustment of band passageway 62 for the steel band of different thickness of this mechanism.

The connecting guide block 70 is provided with a connecting guide groove 71 for passing through the steel belt, one end of the notch at the two ends of the connecting guide groove 71 is aligned with the belt passing channel in the abrasive wire removing mechanism 5, and the other end of the notch is aligned with the belt repairing channel 62 in the steel belt reducing wheel set 57 at the head end. The guide block 70 is used for guiding and limiting the steel belt, so that the situation that the steel belt leans against the convex edge 59 or the outer wall of the first sizing wheel 58 or the outer wall of the second sizing wheel 60 when the abrasive wire removing mechanism 5 enters the steel belt reducing wheel set 57 at the head end is avoided. In the scheme, the width of the guiding groove 71 is the same as the width of the shaping groove 61 on the second shaping wheel 60 in the head-end steel strip reduction wheel set 57, 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 head-end steel strip reduction wheel set 57. So that the steel strip can not transversely move when entering the steel strip reduction wheel set 57 at the head end from the connecting and guiding block 70, and the conveying process is more stable.

A guide block 72 is further arranged between two adjacent steel strip reduction wheel sets 57, a guide groove 73 for passing through a steel strip 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 respectively aligned with the strip repairing passages 62 in the two adjacent steel strip reduction wheel sets 57. The steel belt is guided by the guide groove 73, and the steel belt is prevented from deviating. And the width of the guide groove 73 of the guide block 72 is the same as the width of the sizing groove 61 of the second sizing wheel 60 positioned at the front end of the guide block 72 in the steel strip conveying direction, and the height of the guide groove 73 of the guide block 72 is the same as the depth of the sizing groove 61 of the second sizing wheel 60 positioned at the front end of the guide block 72 in the steel strip conveying direction. Because the size of the belt repairing channel 62 in each steel belt reducing wheel set 57 is different, the width and the height of the guide groove 73 are consistent with the width and the height of the shaping groove 61 on the previous second shaping wheel 60, so that the steel belt is more stable and cannot shake in the conveying process.

And in this embodiment, the guide block 72 is provided with the first arc-shaped surface of outer wheel wall looks adaptation with two adjacent first sizing wheels 58 around both sides of the upper end surface, and the guide block 72 is provided with the second arc-shaped surface of outer wheel wall looks adaptation with two adjacent second sizing wheels 60 around both sides of the lower end surface. So that the guide block 72 can be closer to the first sizing wheel 58 and the second sizing wheel 60 and the guide block 72 can be prevented from interfering with the first sizing wheel 58 and the second sizing wheel 60. Similarly, the approaching block has arc surfaces at the front and rear sides of the upper and lower end surfaces, which are matched with the steel strip reducing wheel set 57 at the head end and the supporting wheel in the abrasive wire removing mechanism 5.

The base 56 is further provided with a guiding-out block 74, the guiding-out block 74 is located behind the plurality of pairs of steel strip reduction wheel sets 57 along the conveying direction of the steel strips, a guiding-out groove 75 for the steel strips to pass through is formed in the guiding-out block 74, and a notch of the guiding-out groove 75 is aligned with the strip trimming channel 62 in the steel strip reduction wheel set 57 located at the tail end.

The steel strip cutting mechanism 7 includes a mounting base 76 and a controller. The mounting seat 76 is arranged at the tail end of the frame 1, and a steel strip outlet for passing through a steel strip is arranged on the mounting seat 76. The steel strip outlet is aligned with the notch of the lead-out groove 75 of the lead-out block 74, and the size of the steel strip outlet is the same as the size of the notch of the lead-out groove 75. And the mounting seat 76 is also provided with a receiving hopper 77, a cutting driving assembly and a cutter 79.

When the controller receives the detection signal, the cylinder drives the push rod to stretch and retract so as to drive the cutting knife 79 to rotate around the hinge point of the cutting knife 79 and the mounting seat 76 to cut off the steel strip at the steel strip outlet.

In this scheme, cutter 79's both sides all have the cutting edge, and the cutting edge divide into cutting edge and lower cutting edge. 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 blade cuts off the steel strip at the steel strip outlet, or the cutter 79 is driven to rotate anticlockwise around the hinge point of the cutter 79 and the mounting seat 76, and the upper blade cuts off the steel strip at the steel strip outlet. If the cutter 79 only has a blade on one side, the cutter 79 needs to be driven to reset each time the steel strip is cut by the cutter 79, and the next cutting can be performed, so that the time consumed by a single process is long. And because both sides of the cutter 79 are provided with the cutting edges, both sides of the cutter 79 can cut the steel belt, the cutter 79 does not need to be driven to reset after the cutter 79 is driven to cut the steel belt every time, the cutter 79 is driven to reversely feed when the steel belt is cut next time, the time consumed by the process is reduced, and the cutting efficiency is improved. For example only, when the steel strip triggers the detecting element 91, the cutter driving cylinder 78 drives the cutter 79 to rotate clockwise around the hinge point between the cutter 79 and the mounting seat 76, and after the lower blade cuts off the steel strip at the steel strip outlet, the cutter 79 stays at the position below the steel strip 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 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 to be collected. When the steel band piles up to predetermineeing quantity in connecing hopper 77, the weight of steel band is greater than the weight of balancing weight 89, and the steel band oppresses swivel plate 87 to rotate for the bottom of swivel plate 87 is relative the fixed plate 86 is kept away from the action and is formed the feed opening of accessible steel band, and the steel band in connecing hopper 77 passes through the feed opening unloading and accomplishes the collection, makes the quantity of the steel band of unloading every time all the same, has saved the step of follow-up steel band partial shipment. 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 abuts against the surface of the fixed plate 86 so as to receive 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 through an elastic member. The detection piece 91 is a travel switch, the travel switch is arranged on the fixing plate 86, a steel belt penetrating out of the steel belt outlet is jacked up, the hinge 100 triggers the travel switch when the fixing plate 86 rotates, the travel switch sends out 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 steel belt outlet, the hinge 100 loses the acting force of the steel belt, and the tension spring 90 drives the hinge 100 to reset. When the steel strip jacking hinge 100 rotates relative to the fixing plate 86, the cutter 79 cuts off the steel strip at the steel strip outlet under the action of the cutting driving assembly, so that the length of each section of steel strip is kept consistent. And because the head end of the steel belt is abutted against the hinge 100, the tail end of the steel belt is limited by the steel belt reducing mechanism 6, and the two ends of the steel belt are stressed, so that the steel belt is in a stretched state, and the cutting of the cutter 79 is facilitated. Meanwhile, the hinge 100 may be automatically restored by the elastic member.

And to avoid bending of the steel strip itself during jacking of the hinge 100. Referring to fig. 15, the bottom of the shaping groove 61 of the second shaping wheel 60 of the last pair of steel strip reduction wheel sets 57 in the steel strip reduction mechanism 6 is an inwardly concave arc-shaped surface. The cross section of the convex edge 59 on the corresponding first shaping wheel 58 is arc-shaped convex. Therefore, the belt surface of the steel belt coming out of the last pair of steel belt reducing wheel sets 57 is not completely flat but slightly provided with a certain arc, the steel belt entering the steel belt cutting mechanism 7 is an arc-shaped special-shaped part, the structural strength of the steel belt is improved, and the problem that the hinge 100 cannot trigger a travel switch due to the fact that the hinge 100 cannot be pushed away due to the fact that the steel belt is bent after the steel belt collides with the hinge 100 is solved.

In addition, as shown in fig. 20, an oil inlet rod 92 is further disposed on the partition 83, an oil inlet passage is disposed on the oil inlet rod 92 along the length direction of the oil inlet rod 92, an oil hole 93 is disposed on the oil inlet rod 92, and the oil hole 93 is connected to the oil inlet passage. Meanwhile, a through hole is formed in the partition 83, and the oil inlet channel is communicated with the cutting channel 84 through the through hole. Oil is added through the oil hole 93, and the oil enters the cutting channel 84 along the oil inlet channel to lubricate the cutter 79.
