Description

Technical Field

[0001] This utility model relates to the field of rubber roller manufacturing technology, and in particular to a rubber roller clamping mechanism that facilitates clamping. Background Technology

[0002] A rubber roller clamping mechanism is a mechanical device used to fix, position, and support rubber rollers, ensuring that the rubber rollers maintain a stable position and correct posture during processing, assembly, or use to meet process requirements.

[0003] In existing technologies, conventional clamping mechanisms use two arc-shaped clamping plates to simultaneously hold the rubber roller. The positioning and fixation are achieved by the contact between the curved surfaces of the clamping plates and the outer circumference of the rubber roller, providing a reference support for subsequent processing steps such as cutting and grinding. However, the arc-shaped clamping plates are only suitable for rubber rollers of a specific diameter. When the size of the rubber roller changes, the curvature of the rubber roller does not match the curvature of the arc-shaped clamping plates, or the diameter of the rubber roller exceeds the preset range, the contact area between the arc-shaped clamping plates and the rubber roller will be small. This results in insufficient friction to position the rubber roller, and the insufficient contact area leads to uneven distribution of friction. Under the action of cutting forces, the rubber roller is prone to axial movement or circumferential slippage. Stress concentration in local contact areas may cause indentations on the surface of the rubber roller or wear on the clamping plates. Therefore, it is necessary to improve the rubber roller clamping mechanism to solve the above problems. Utility Model Content

[0004] To overcome the problem of insufficient friction caused by a fixed-size curved clamping plate facing a rubber roller with a mismatch in curvature.

[0005] The technical solution of this utility model is as follows: a rubber roller clamping mechanism for easy clamping, including a base plate, a support frame and an adjustment mechanism. The adjustment mechanism is set on the base plate, and the support frame is set on the base plate and the adjustment mechanism respectively. A limit plate is fixedly connected to the support frame, and a groove block is slidably connected to the limit plate. A reset spring is fixedly connected between the groove block and the limit plate to reset the groove block. A sliding column is fixedly connected to the inner side of the groove block, and a rubber pad that increases friction with the rubber roller is fixedly connected to the end of the sliding column away from the groove block.

[0006] Preferably, the limiting plate has a sliding groove at the corresponding position of the slot block, and the slot block slides inside the sliding groove.

[0007] Preferably, a roller is rotatably connected to the groove block, a push plate that cooperates with the roller is rotatably connected inside the limiting plate, a connecting frame is fixedly connected to the outside of the push plate, a positioning plate is fixedly connected to the outside of the limiting plate, a first threaded rod is rotatably connected to the positioning plate, a movable block is threadedly connected to the first threaded rod, and the movable block is movably connected inside the connecting frame.

[0008] Preferably, the push plate is provided with an inclined surface, and the push plate contacts the roller through the inclined surface.

[0009] Preferably, the limiting plate has a through groove at the corresponding position of the connecting frame, and the connecting frame passes through the through groove. The connecting frame has a limiting groove at the corresponding position of the movable block, and the movable block is movably connected inside the limiting groove.

A locking block is threaded onto the second threaded rod and is slidably connected to the slide plate.

[0011] Preferably, the skateboard has a groove that matches the support frame, and the support frame is located inside the groove, with the locking block in contact with the support frame.

[0012] The beneficial effects of this utility model are:

[0021] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0022] Please see Figures 1-5 This utility model provides an embodiment of a convenient clamping mechanism for rubber rollers, including a base plate 1, a support frame 21, and an adjustment mechanism. The adjustment mechanism is mounted on the base plate 1, and the support frame 21 is mounted on both the base plate 1 and the adjustment mechanism. A limiting plate 22 is fixedly connected to the support frame 21, and a groove block 23 is slidably connected to the limiting plate 22. A return spring 24 is fixedly connected between the groove block 23 and the limiting plate 22 to reset the groove block 23. A sliding column 25 is fixedly connected to the inner side of the groove block 23, and a rubber pad 26 is fixedly connected to the end of the sliding column 25 away from the groove block 23 to increase friction with the rubber roller. The position of a support frame 21 and a limiting plate 22 is adjusted individually by the adjustment mechanism. Then, the rubber roller is aligned with the center position of the limiting plate 22. The limiting plate 22 is reset by the adjustment mechanism. Then, the groove block 23 slides to drive the sliding column 25. The sliding column 25 drives the rubber pad 26. The rubber pad 26 clamps the rubber roller. Ten sliding columns 25 simultaneously clamp the rubber roller through the rubber pad 26, so that subsequent processing of the rubber roller can be carried out. The rubber pad 26 is relatively thin. When the rubber roller is clamped by the push of the sliding column 25, it will be compressed to the minimum. The elasticity of the rubber pad 26 will not affect the subsequent processing of the rubber roller.

[0023] Please see Figures 1-4In this embodiment, the limiting disk 22 has a groove at the corresponding position of the slot block 23, and the slot block 23 slides inside the groove. The groove limits the movement of the slot block 23, allowing it to slide linearly and avoiding jamming caused by tilting. This ensures smooth movement of the slot block 23. A roller 27 is rotatably connected to the slot block 23. A push disk 28 that cooperates with the roller 27 is rotatably connected inside the limiting disk 22. A connecting frame 29 is fixedly connected to the outside of the push disk 28. A positioning plate 210 is fixedly connected to the outside of the limiting disk 22. A first threaded rod 211 is rotatably connected to the positioning plate 210. A movable block 212 is threadedly connected to the first threaded rod 211. The movable block 212 is movably connected inside the connecting frame 29. Rotating the first threaded rod 211 can push the sliding column 2. The roller descends, allowing for appropriate adjustment based on its size, thus enabling the clamping of rollers of different sizes. It features a large contact area and sufficiently stable positioning. The push plate 28 has an inclined surface that contacts the roller 27. This inclined surface allows for flexible adjustment of the sliding column 25, while the roller 27 reduces friction, resulting in smoother position adjustment and preventing jamming. The limiting plate 22 has a through groove at the corresponding position of the connecting frame 29, through which the connecting frame 29 passes. The connecting frame 29 has a limiting groove at the corresponding position of the movable block 212, which is movably connected inside the limiting groove. This limiting groove ensures the movable block 212 remains connected inside, preventing detachment. Thus, the movable block 212 can drive the connecting frame 29 to move.

[0024] Please see Figure 1 , Figure 5 In this embodiment, the adjustment mechanism includes an electric telescopic rod 31, which is fixedly connected to the base plate 1. A slide plate 32 is fixedly connected to the left side of the electric telescopic rod 31. A second threaded rod 33 is rotatably connected to the slide plate 32. A locking block 34 is threadedly connected to the second threaded rod 33. The locking block 34 is slidably connected to the slide plate 32. The position of the support frame 21 can be appropriately adjusted by the extension and retraction of the electric telescopic rod 31, thereby adjusting according to the length of the rubber roller, which facilitates the loading and unloading of rubber rollers of different lengths. The slide plate 32 has a groove adapted to the support frame 21, and the support frame 21 is set inside the groove. The locking block 34 contacts the support frame 21. The groove facilitates the assembly of the support frame 21, and the locking block 34 is used for positioning. The support frame 21 can be disassembled and replaced as needed.

[0025] During operation, the electric telescopic rod 31 drives the slide plate 32, which in turn moves the right-side limiting plate 22. The rubber roller is then placed in the center of the limiting plate 22, and then reset by the electric telescopic rod 31. Twisting the first threaded rod 211 drives the movable block 212, which in turn drives the connecting frame 29. The connecting frame 29 drives the push plate 28 to rotate, and the push plate 28 pushes the groove block 23 through the roller 27. The groove block 23 drives the sliding column 25, which in turn compresses the reset spring 24. The sliding column 25 drives the rubber pad 26, which clamps the rubber roller. All ten sliding columns 25 clamp the rubber roller through the rubber pad 26. Twisting the second threaded rod 33 rotates the locking block 34, which slides away from the support frame 21, allowing the support frame 21 to be disassembled.

[0026] Through the above steps, the ten sliding columns 25 slide synchronously, clamping the rubber roller at the center of the limiting plate 22. The rubber pad 26 increases friction, thereby stably clamping the rubber roller to solve the problem of insufficient friction caused by the fixed-size arc-shaped clamping plate facing the rubber roller with mismatched arc size.
