Description

Technical Field

[0001] This utility model relates to the field of pinch roller technology, specifically a pinch roller that is easy to adjust and use. Background Technology

[0002] Pinch rolls are used to help the head of the wire rolled out by the finishing mill enter the coiler and prevent the tail of the high-speed wire from accelerating due to loss of restraint when exiting the mill, which could cause a blockage accident.

[0003] The existing Chinese utility model patent with publication number CN218903079U discloses an adjustable pinch roller, including a base, a right support column, and a left support column. The right support column is slidably connected to the top right side of the base, and the left support column is fixedly connected to the top left side of the base. A first groove is formed on the lower side of the left side wall of the right support column, and a bearing is rotatably connected to the inner cavity of the first groove. A drive roller is sleeved in the inner cavity of the bearing. A second sliding groove is formed on the upper side of the left side wall of the right support column. A second motor is fixedly connected to the top of the right support column, and a second lead screw is fixedly connected to the end of the power output shaft of the second motor. The end of the second lead screw passes through the right support column and extends to the bottom of the inner cavity of the second sliding groove. This adjustable pinch roller has a reasonable structural design, which allows the pinch roller to be adjusted according to the conveying requirements and allows for convenient and quick disassembly of the pinch roller, improving maintenance efficiency.

[0004] While the aforementioned adjustable pinch roller solves the problems of existing pinch rollers being unable to be adjusted according to material thickness and the inconvenience of disassembly and assembly of general pinch rollers by starting the second motor to drive the second lead screw, the driven roller is not conducive to buffering, resulting in poor clamping effect, gaps in clamping, and the lack of buffering when the clamped item shakes, which can easily lead to damage to the equipment or the clamped item. In addition, the existing equipment is not convenient for adjusting the buffering structure. Utility Model Content

[0005] The purpose of this invention is to overcome the problems of existing technologies that are not convenient for buffering and for adjusting the buffering structure, and to provide a pinch roller that is easy to adjust and use.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0012] In a preferred embodiment, a side plate is fixedly installed at the bottom of the lifting trough, and a motor is fixedly installed on one side of the side plate. The motor is a structure used to drive the rotating roller to rotate.

[0013] In a preferred embodiment, a rotating roller is fixedly installed on one side of the motor, and two support columns are fixedly installed on both sides of the side plate. The support columns are structures used to wrap around the outside of the lifting column.

[0014] In a preferred embodiment, a lifting column is fixedly installed inside the support column, and a base plate is fixedly installed at the bottom of the lifting column. The base plate is a structure used to support the bottom.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This easy-to-adjust pinch roller, through the contraction of the spring, can drive the insertion groove to move up and down inside the support groove, thereby giving the driven roller a buffering effect and a downward clamping force, avoiding the problem of clamping gaps.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Combined with appendix Figures 1-5 In this embodiment, a pinch roller that is easy to adjust and use includes: a support plate 1, a lifting rod 11 fixedly installed in the middle of the support plate 1, a limit plate 12 fixedly installed at the bottom of the lifting rod 11, two support grooves 13 fixedly installed inside both sides of the support plate 1, a rotator 14 fixedly installed at the top of the support groove 13, a threaded rod 15 fixedly installed at the bottom of the rotator 14, and a baffle 16 fixedly installed at the bottom of the threaded rod 15.

[0026] Specifically, the rotation of the rotator 14 can drive the threaded rod 15 to rotate, thereby driving the lifting block 2 to rise and fall. The baffle 16 limits the movement, and the lifting rod 11 can be raised and lowered so that the limiting plate 12 can be attached to the top of the driven roller 24 for support and limitation.

[0027] A lifting block 2 is movably connected to the middle outer side of the threaded rod 15. A spring 21 is fixedly installed at the bottom of the lifting block 2. An insertion groove 22 is fixedly installed at the bottom of the spring 21. A limit block 23 is fixedly installed at the bottom of the insertion groove 22. A driven roller 24 is fixedly installed at the bottom of the limit block 23.

[0028] Specifically, the driven roller 24 can clamp the top of the item, and the spring 21 can be contracted to allow the insertion slot 22 to rise and fall inside the support slot 13 for support. The tension of the spring 21 can be adjusted by raising and lowering the lifting block 2.

[0029] Two lifting plates 31 are fixedly installed on both sides of the support plate 1, and lifting grooves 3 are movably connected to the outer side of the lifting plates 31.

[0030] A threaded column 32 is movably connected in the middle of the lifting plate 31, and a rotating shaft 33 is fixedly installed at the bottom of the threaded column 32.

[0031] A rotating device 34 is fixedly installed on the top of the threaded column 32.

[0032] Specifically, the operation of the rotating device 34 can drive the threaded column 32 to rotate at the top of the rotating shaft 33, thereby driving the lifting plate 31 to rise and fall, so that the lifting plate 31 can move up and down inside the lifting groove 3.

[0033] A side plate 4 is fixedly installed at the bottom of the lifting trough 3, and a motor 41 is fixedly installed on one side of the side plate 4.

[0034] A rotating roller 42 is fixedly installed on one side of the motor 41, and two support columns 43 are fixedly installed on both sides of the side plate 4.

[0035] A lifting column 44 is fixedly installed inside the support column 43, and a base plate 45 is fixedly installed at the bottom of the lifting column 44.

[0036] Specifically, the bottom is supported by the base plate 45, and the lifting column 44 is raised and lowered inside the support column 43, which can drive the side plate 4 to rise and fall, thereby adjusting the height of the rotating roller 42. The operation of the motor 41 can drive the rotating roller 42 to rotate.

[0037] Working Principle: First, the easily adjustable pinch roller is supported at the bottom by the base plate 45. The height of the two side plates 4 is adjusted by the raising and lowering of the lifting column 44 inside the support column 43, so that the rotating roller 42 can be adjusted to a suitable height. The operation of the motor 41 can drive the rotating roller 42 to rotate, thereby conveying materials, which improves the practicality and adjustability of the easily adjustable pinch roller. The operation of the rotating device 34 at the top of the lifting groove 3 can drive the threaded column 32 at its bottom to rotate. The threaded column 32 is supported by the rotating shaft 33 at its bottom. The rotation of the threaded column 32 can drive the lifting plate 31 to rise and fall inside the lifting groove 3, thereby facilitating the adjustment of the height of the driven roller 24 of the easily adjustable pinch roller, so as to pinch materials of different sizes, which improves the practicality and convenience of the easily adjustable pinch roller. The contraction of the spring 21 can drive the insertion groove 22 to move up and down inside the support groove 13, thereby giving the driven roller 24 a buffering effect. This design avoids damage to the equipment or materials caused by material vibration during material feeding, and also prevents jamming due to changes in material diameter. The spring 21 generates a reaction force, improving the clamping effect and preventing gaps that could lead to poor conveying performance. This enhances the practicality of the adjustable clamping roller. The rotation of the rotator 14 drives the threaded rod 15 to rotate, which in turn moves the lifting block 2 up and down. Adjusting the tension of the spring 21 allows for adjustment of the clamping and buffering force of the driven roller 24, further improving the ease of use. The baffle 16 limits and blocks the lifting block 2, preventing it from falling off. When buffering is not needed, the lifting rod 11 moves the limiting plate 12 downwards, causing it to fit against the top of the driven roller 24, preventing buffering and improving the practicality and adjustability of the adjustable clamping roller.

[0038] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
