Detailed Description

For a further understanding of the utility model, 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.

Example 1: referring to fig. 1 to 3 and 6 to 9, the present embodiment provides a waterproof type lifting assembly, which is a component of a wire rod surface treatment apparatus, which will be described below. Wire rod surface treatment device, including frame 1, be provided with in frame 1 and be used for carrying out the treatment roller 2 that rust cleaning to the wire rod surface, and the both sides of treating roller 2 all are provided with wire rod stabilizing mean.

Wire rod stabilizing mean includes compression roller 3, compression roller 4 and waterproof type lifting unit 5 down, and last compression roller 3, compression roller 4 and waterproof type lifting unit 5 all set up in frame 1 down. Wherein the upper press roll 3, the lower press roll 4 and the processing roll 2 are parallel to each other, and a gap is left between the upper press roll 3 and the lower press roll 4 in the vertical direction to form a strip passing channel 6 capable of passing through a wire rod.

In addition, as a preferred embodiment, a plurality of annular groove-shaped roller ways 7 are arranged on the upper press roll 3 and the lower press roll 4 at intervals along the length direction of the upper press roll and the lower press roll, and the roller ways 7 of the upper press roll 3 and the roller ways 7 of the lower press roll 4 are in one-to-one correspondence and are mutually matched to form the strip passing channel 6. Each wire rod passes through the corresponding wire passing channel 6 and is fed to the treatment roller 2 for derusting. Spacing about going on the wire rod through the roll table 7 of cyclic annular cell type for the wire rod can be fixed at rust cleaning in-process position, and mutual noninterference between wire rod and the wire rod can be simultaneously to the synchronous rust cleaning of stranded wire rod or tens strand of strands even, and the rust cleaning efficiency improves by a wide margin.

Meanwhile, the upper pressing roller 3 and the lower pressing roller 4 are staggered with each other along the length direction of the strip passage 6 in the scheme. It is easy to understand that if the upper press roll 3 and the lower press roll 4 are overlapped with each other in the horizontal direction, when the upper press roll 3 and the lower press roll 4 clamp the wire rod, the upper end and the lower end of the wire rod are directly attached to the roll surfaces of the upper press roll 3 and the lower press roll 4, and the feeding is difficult. And when the upper press roll 3 and the lower press roll 4 do not clamp the wire rod tightly, the wire rod shakes to influence the derusting effect. And through last compression roller 3 in this scheme, lower compression roller 4 staggers in proper order along the length direction of crossing a passageway 6 with handling roller 2, even the upper and lower both ends of wire rod are direct with last compression roller 3, the roll surface of lower compression roller 4 is hugged closely, because last compression roller 3, lower compression roller 4 is in the state of staggering, there is a position at the upper and lower both ends of wire rod on the same horizontal position and does not lean on with other parts and lean on, the problem that is difficult to feed can not appear, but again because last compression roller 3, the roll surface of lower compression roller 4 is spacing from top to bottom to the wire rod, the wire rod can not appear the problem that the shake influences the rust cleaning effect yet, it is good to press from both sides tight effect.

And a waterproof lifting component 5 in the wire rod stabilizing mechanism is connected with one of the upper pressing roller 3 and the lower pressing roller 4 and is used for driving the connected upper pressing roller 3 or the lower pressing roller 4 to move close to or away from the other one of the upper pressing roller 3 and the lower pressing roller 4 in the vertical direction so as to adjust the size or the trend of the wire rod passage 6.

Referring to fig. 6-9, the waterproof lifting assembly 5 includes a screw rod lifter 8, a bearing seat 15 is connected to the screw rod lifter 8, an upper press roller 3 or a lower press roller 4 is disposed on the bearing seat 15, and the screw rod lifter 8 drives the bearing seat 15 to move so as to drive the upper press roller 3 or the lower press roller 4 to move close to or away from the other of the upper press roller 3 and the lower press roller 4.

Specifically, the upper compression roller 3 is mounted on the bearing seat 15 through a bearing seat in the scheme. Waterproof type lifting unit 5 still includes fixing base 13, and fixing base 13 sets up in frame 1, and the length direction of fixing base 13 is the same with the length direction of handling roll 2. The screw rod lifter 8 is fixedly arranged on the fixed seat 13. The screw rod lifter 8 comprises a worm gear reducer, and the worm gear reducer is connected with a screw rod assembly and a driving rod 10. Wherein the driving rod 10 extends out of the frame 1 along the length direction of the fixed seat 13 and is connected with a rotating handle 11. Of course, it is also possible to connect a drive motor to the drive rod 10.

The screw rod assembly comprises a screw rod 9 in the scheme, and a guide rod 12 is connected to the screw rod 9. As a better connection mode, the connection mode of the screw rod 9 and the guide rod 12 is hinged. If a flanged connection is used, the diameter of the guide rod 12 must be large, which increases the cost of the product. And by adopting the hinged connection mode, the guide rod 12 with a small diameter can be adopted, and the hinged connection mode is flexible connection, so that a certain protection effect on equipment is also realized. Meanwhile, the fixed seat 13 is provided with a guide channel 14, and the guide rod 12 penetrates through the guide channel 14 on the fixed seat 13 and is connected with the bearing seat 15. The worker can rotate the handle 11 to drive the screw rod 9 in the screw rod lifter 8 to drive the guide rod 12 to slide in the guide channel 14, so as to drive the bearing seat 15 and the upper press roll 3 on the bearing seat 15 to move close to or away from the lower press roll 4 to adapt to wire rods with different diameters. Because the guide rod 12 is not arranged beside the screw rod lifter 8, the fixed seat 13 does not need to be provided with the width for additionally arranging the guide rod 12, and the whole volume is greatly reduced. And because the guide rod 12 is arranged on the screw rod 9 of the screw rod lifter 8, the guide rod 12 can not interfere with the driving rod 10. Of course, it is also possible to connect the spindle 9 directly to the carrier.

In this embodiment, the bearing seat 15 and the fixing seat 13 are both strip-shaped portions, and the length direction of the bearing seat 15 is the same as the length direction of the fixing seat 13. And the number of the screw rod lifters 8 is a plurality, a plurality of screw rod lifters 8 are arranged at intervals along the length direction of the bearing seat 15, and two adjacent screw rod lifters 8 are in transmission connection through a transmission rod 27. Because the press roller is in a strip shape, the corresponding bearing seat 15 adopts a strip-shaped part body. And through being provided with a plurality of lead screw lifters 8 make to bear the lift of seat 15 more steady, and fixing base 13 is the strip portion body, and a plurality of lead screw lifters 8 are arranged along the length direction interval that bears seat 15, have reduced equipment width by a wide margin, have reduced equipment occupation space.

And waterproof type lifting unit 5 in this scheme still includes mount pad 16, and as a better mounting means, mount pad 16 sets up on fixing base 13, and mount pad 16 and bear seat 15 and be located the opposite both sides of fixing base 13. The worm gear lifter is arranged on the mounting seat 16, a cavity 17 is arranged in the mounting seat 16, through holes 18 communicated with the cavity 17 are formed in two opposite ends of the mounting seat 16, and the guide rod 12 and the screw rod 9 respectively penetrate through the through holes 18 in the two ends of the mounting seat 16 and are connected in the cavity 17. By providing the mounting seat 16 on the fixed seat 13, the sliding stroke of the lead screw 9 and the guide rod 12 is increased by mounting the lead screw lifter 8 on the mounting seat 16 as compared with directly mounting the lead screw lifter 8 on the fixed seat 13. If the screw rod lifter 8 is directly mounted on the fixed seat 13 and a screw rod 9 and a guide rod 12 having the same length as those in fig. 9 are to be mounted on the fixed seat 13, the thickness of the fixed seat 13 is greatly increased, and the cost is undoubtedly increased. And the installation seat 16 is arranged, so that the thickness of the fixed seat 13 is greatly reduced, the extra length of the screw rod 9 and the guide rod 12 is accommodated in the installation seat 16, and the product cost is reduced.

In order to enable the mounting seat 16 to be smoothly mounted on the fixing seat 13, as shown in fig. 9, the waterproof lifting assembly 5 further includes a mounting plate 22, the mounting plate 22 has a front end surface and a rear end surface along a thickness direction thereof, the front end surface of the mounting plate 22 is attached to and fixedly connected with an outer wall of the fixing seat 13, and the mounting seat 16 is mounted on the rear end surface of the mounting plate 22. And the mounting base 16 is also provided with jacks penetrating through the front end face and the rear end face of the mounting base, the jacks are communicated with through holes 18 on the mounting base 16, and the guide rod 12 sequentially penetrates through the through holes 18 and the jacks to extend into the guide channel 14.

A waterproof cover 19 is also arranged on the mounting base 16, and the worm gear lifter is positioned in the waterproof cover 19. It is easy to understand that the treatment roller 2 needs to be continuously injected with water to cool and suck dust during the treatment of the surface of the wire rod, and if the water flow splashes or flows into the screw rod lifter 8, the parts can be damaged. The waterproof cover 19 plays a waterproof role, and water is prevented from flowing into the screw rod lifter 8.

Meanwhile, in this embodiment, the openings at both ends of the guide channel 14 are provided with water stop collars 20, the outer annular wall of the water stop collar 20 is attached to the inner wall of the guide channel 14, and the inner annular wall of the water stop collar 20 is attached to the rod wall of the guide rod 12. And the guide rod 12 is also sleeved with a waterproof sleeve 21, and two ends of the waterproof sleeve 21 are respectively connected with the fixed seat 13 and the bearing seat 15. When the bearing seat 15 moves closer to the fixed seat 13, the waterproof jacket 21 is compressed. When the bearing seat 15 moves away from the fixed seat 13, the waterproof jacket 21 is unfolded. The waterproof sleeve 21 prevents the guide rod 12 exposed outside the guide channel 14 from being stained with liquid or dust, so that the liquid or dust is prevented from flowing into the screw 9 and the screw lifter 8 along the guide rod 12 through the guide channel 14. The water stop collar 20 can further prevent water from flowing into the guide channel 14, further protect the guide rod 12 and the screw rod 9, prevent dust from falling into the guide channel 14 to interfere with the sliding of the guide rod 12, and prolong the service life of the components.

Although the waterproof type lifting assembly 5 has a certain waterproof function through the waterproof cover 19, the water stop collar 20 and other components, it is inevitable that moisture enters the mounting seat 16. In the scheme, the water flowing groove 23 is arranged on the rear end face of the mounting plate 22, the water flowing groove 23 penetrates through the side wall of one side of the mounting plate 22, the water flowing groove 23 is communicated with the through hole 18, and condensed water vapor is discharged from the water flowing groove 23 through the water flowing groove 23.

In addition, the frame 1 is provided with a support seat 24, and the support seat 24 is overlapped with the processing roller 2 in the length direction of the strip passage 6. The upper compression roller 3 or the lower compression roller 4 which is not connected with the waterproof lifting component 5 in the wire rod stabilizing mechanisms on the two sides of the processing roller 2 are respectively arranged on the two sides of the supporting seat 24. And the upper compression roller 3 or the lower compression roller 4 which is not connected with the waterproof lifting component 5 in the wire rod stabilizing mechanism is a first compression roller, the upper compression roller 3 or the lower compression roller 4 which is connected with the waterproof lifting component 5 in the wire rod stabilizing mechanism is a second compression roller, and the first compression rollers in the two wire rod stabilizing mechanisms are positioned between the second compression rollers in the two wire rod stabilizing mechanisms.

Because last compression roller 3 of this scheme is installed on the bearing seat 15 in waterproof type lifting unit 5, so first compression roller in this scheme is compression roller 4 down, and the second compression roller is compression roller 3 promptly. The lower compression rollers 4 of the two wire rod stabilizing mechanisms are arranged on two opposite sides of the supporting seat 24, and the two lower compression rollers 4 are positioned between the two upper compression rollers 3.

Because the upper compression roller 3 is driven by the waterproof lifting component 5 to lift up and down to adjust the size or the trend of the strip passage 6, the two upper compression rollers 3 cannot be guaranteed to be at the same horizontal height after being lifted. However, the height position of the lower roll 4 in the vertical direction is fixed, so that the two lower rolls 4 can be kept at the same horizontal height. And because the two lower press rolls 4 are arranged on two opposite sides of the supporting seat 24, the supporting seat 24 is overlapped with the processing roll 2 in the length direction of the strip passing channel 6, and the two lower press rolls 4 are arranged between the two upper press rolls 3. The wire rod between the two lower rollers 4 is fed horizontally so that the processing roller 2 processes the surface of the wire rod.

And furthermore, in the scheme, the processing roller 2, the waterproof lifting component 5 and the upper compression roller 3 connected with the waterproof lifting component 5 are all positioned at the same end (namely the upper end) of the upper end and the lower end of the channel 6 in the vertical direction. The lower press roll 4 which is not connected with the waterproof lifting component 5 is positioned at the other end (namely the lower end) of the upper end and the lower end of the strip passage 6, and the lower press roll 4 and the rack 1 are kept relatively fixed in the vertical direction. Because waterproof type lifting unit 5 and last compression roller 3 are in the upper end in the upper and lower both ends of strip passageway 6 with processing roller 2 in vertical direction, and the lower compression roller 4 that is located the lower extreme of strip passageway 6 is just immovable, the interval that is located the lower compression roller 4 of the lower extreme of strip passageway 6 and is handled between the roller 2 in vertical direction is the same, as long as lower compression roller 4 is in vertical direction and the diameter of the wire rod of the interval between processing roller 2, when waterproof type lifting unit 5 promoted the last compression roller 3 oscilaltion that links then, even remove and exceed the stroke and also can not make the roll surface of wire rod and processing roller 2 break away from. Specifically, in the present embodiment, the supporting seat 24 is disposed above the strip passing channel 6, and the supporting seat 24 is staggered from the processing roller 2 along the length direction of the strip passing channel 6.
