Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, specifically to a slitting machine rubber roller replacement mechanism. Background Technology

[0002] Aluminum foil production requires slitting machines to efficiently and quickly cut the aluminum foil. The main components of a slitting machine include rubber rollers. These rollers are driven by a motor, providing the primary power for the machine. During operation, aluminum foil is adhered to the rollers using tape or similar methods. The rollers then rotate, pulling the aluminum foil along with other components of the slitting machine to cut it. To increase friction and stabilize the aluminum foil, the rollers are made of rubber, resulting in a relatively heavy roller. Manual replacement often requires 4-6 operators, involving multiple tasks such as receiving and disassembling the rollers.

[0003] The utility model patent with announcement number CN219429283U provides a quick-change rubber roller structure. By using detachable connecting parts to fix and limit the bearing at the instructor end, the rubber roller can be transferred and transported in a narrow area, shortening the maintenance time. However, the rubber rollers of the slitting machine are mostly installed in pairs, and each rubber roller in this technical solution requires a corresponding replacement structure, which is inconvenient. Utility Model Content

[0004] The purpose of this invention is to provide a slitting machine replacement mechanism to reduce the difficulty of replacing rubber rollers and improve the efficiency of rubber roller replacement.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A slitting machine roller replacement mechanism includes an upper roller and a lower roller arranged in pairs inside the slitting machine. A sliding groove is laterally arranged inside the slitting machine, and a mounting plate is slidably connected to the sliding groove. The end face of the upper roller is detachably connected to the piston end of a lifting cylinder. The mounting plate is detachably connected to the end face of the lower roller. A roller support block is provided on the top of the mounting plate. The roller support block is also provided with a first cable and a hook adapted to the first cable. The lifting cylinder is electrically connected to an industrial control board through a reversing valve.

[0007] Furthermore, the mounting plate moves along the slide groove via a chain, the chain being connected to a sliding motor via a sprocket, and the sliding motor being electrically connected to the industrial control board.

[0008] Furthermore, the bearing roller block is detachably connected to the mounting plate, the bottom of the bearing roller block is provided with an opening that fits the mounting plate, and a sprue bolt is provided through the side of the opening.

[0009] Furthermore, a first arc-shaped support plate is provided on the top surface of the bearing roller block, and the first arc-shaped support plate is adapted to the gluing roller.

[0010] Furthermore, a second arc-shaped support plate is provided extending downward from the side of the opening away from the rubber roller, and the second arc-shaped support plate is adapted to the lower rubber roller.

[0011] Furthermore, a guide rod is provided on the second arc-shaped support plate, which passes downward through the bearing roller block. A spring is sleeved on the guide rod, and the two ends of the spring abut against the bottom surfaces of the bearing roller block and the second arc-shaped support plate, respectively. A limit block is provided at the end of the guide rod.

[0012] Furthermore, the hook includes a locking tongue and a locking buckle. The locking tongue is hinged to one side of the bearing roller block, and the locking buckle is a sleeve sleeved on the end of the hook. Both the end of the locking tongue away from the hinge and the end of the hook are provided with external threads. The sleeve is provided with internal threads adapted to the external threads. An inclined surface is provided between the locking tongue and the hook.

[0013] Furthermore, the bottom surface of the bearing roller block is provided with casters.

[0014] Furthermore, a telescopic rod is hinged to the side of the bearing roller block away from the rubber roller, and the telescopic rod is detachably connected to the bearing roller block via a magnet.

[0015] Furthermore, the chute, bearing roller block, and lifting cylinder are symmetrically arranged on both sides of the rubber roller, and the bearing roller block is also provided with a second chain.

[0016] The advantages and beneficial effects of this utility model are as follows:

[0017] 1. The sliding groove and mounting plate work together to achieve the overall horizontal movement of the rubber roller. The lifting cylinder controls the lifting of the upper rubber roller, allowing the two rollers to be disassembled and assembled simultaneously and sent out of the slitting machine in one go. This reduces the time for manual roller changing and lowers the difficulty of replacement, making it suitable for narrow operating spaces.

[0018] 2. The first / second arc-shaped support plate is adapted to the curved surfaces of the upper and lower rubber rollers, and the spring buffer mechanism achieves precise positioning and flexible contact. The detachable bearing roller block can be quickly installed and removed with the ingot head bolts to adapt to different specifications of rubber rollers. The design of universal wheels and telescopic pull rod realizes integrated transfer and reduces the handling intensity.

[0019] 3. The lifting cylinder and sliding motor are centrally controlled by the industrial control board to achieve semi-automatic operation. The first chain, together with the hooks of the inclined plane and the threaded sleeve, fully ensures the relative stability of the upper and lower rubber rollers.

[0020] 4. The symmetrically arranged bearing roller blocks can form a transfer mechanism through the second chain and hooks to transport the rubber rollers. Attached Figure Description

[0026] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0027] Example

[0028] Please see Figures 1-3 This utility model relates to a slitting machine roller replacement mechanism, which is an innovative improvement based on the paired upper roller 1 and lower roller 2 installed inside the slitting machine. It includes a sliding groove 3 laterally arranged inside the slitting machine and a mounting plate 4 that slides with it. The upper roller 1 is detachably connected via the piston end of a lifting cylinder 5, while the lower roller 2 is detachably connected to the end face of the mounting plate 4. The sliding groove 3 drives the mounting plate 4 to move horizontally along the front-to-back direction of the slitting machine via a chain 9 transmission system. The chain 9 is driven by a sliding motor 11 connected to a sprocket 10. Both the lifting cylinder 5 and the sliding motor 11 are centrally controlled via an industrial control board, forming a semi-automatic operation system. The upper roller 1 and lower roller 2 can be simultaneously disassembled and removed from the slitting machine as a whole, thus significantly reducing manual operation time. It is particularly suitable for space-constrained working environments.

[0029] In terms of the load-bearing structure, the top of the mounting plate 4 is provided with a roller support block 6, and the bottom surface of the roller support block 6 is provided with an opening 12 for connecting the mounting plate 4. A swivel bolt 13 is provided through the side of the opening 12 to enable quick assembly and disassembly. The first arc-shaped support plate 14 on the top of the roller support block 6 is adapted to the curved surface of the upper rubber roller 1. The second arc-shaped support plate 15 passes through the roller support block 6 and is provided with a guide rod 16. A spring 17 is sleeved on the guide rod 16 that passes through the roller support block 6. The end of the guide rod 16 is provided with a limiting block 18. The second arc-shaped support plate 15 and the lower rubber roller 2 are made into flexible contact through the spring 17 buffer mechanism, thereby providing buffering and maintaining a stable posture when the rubber roller is loaded.

[0030] The first chain 7 and the hinged hook 8 are connected by a bevel 22, and the locking tongue 19 is fastened to the end of the hook 8 by a threaded sleeve 21. When the locking tongue 19, hinged to one side of the bearing roller block 6, rotates to align with the bevel 22 of the hook 8, the sleeve 21 is tightened to close the hook 8 and secure the first chain 7, achieving double fixation. The second chain 25 works in conjunction with the hook 8 to form a balanced load-bearing frame during transport, facilitating the transport and loading of the rubber roller.

[0031] To enhance the ease of transfer, a caster wheel 23 is added to the bottom of the bearing roller block 6, and a telescopic pull rod 24 that can be magnetically fixed is hinged to the side to form an integrated transfer system. The second chain 25 forms an axial connection between the two symmetrically arranged bearing roller blocks 6. The pull rod 24 can be telescopic and magnetically locked to leave operating space for the assembly of the bearing roller blocks 6 in the slitting machine.

[0032] The working principle of this utility model is as follows: After the operator starts the replacement program, the industrial control board synchronously controls the lifting cylinder 5 to descend. The piston end of the lifting cylinder 5 drives the upper rubber roller 1 to vertically lower its height, reducing the distance between it and the lower rubber roller 2 to a state that facilitates transportation and operation. The bearing roller block 6 is inserted into the mounting plate 4 along the opening 12, and the position of the bearing roller block 4 is adjusted to support the upper and lower rubber rollers. Then, the ingot-head bolt 13 is tightened to fix the bearing roller block 6. After the upper rubber roller 1 is disassembled, it is supported by the first arc-shaped support plate 14. Then, the first chain 7 is wrapped around the lower rubber roller 2 once and locked with the hook 8 to connect the upper and lower rubber rollers into one piece. The connection between the lower rubber roller 2 and the mounting plate 4 is disassembled, so that the side of the lower rubber roller 2 is attached to the second arc-shaped support plate 15. The sliding motor 11 is started to drive the chain 9, which drives the mounting plate 4 to move horizontally along the slide 3 to the outside of the slitting machine. During the translation process, the second arc-shaped support plate 15, which is in contact with the lower rubber roller 2, is buffered by the spring 17. The inertial impact is offset by the extension and retraction of the guide rod 16, and the limiting block 18 at the end of the guide rod 16 prevents the second arc-shaped support plate 15 from falling off, thereby ensuring the stability of the rubber roller posture. At the same time, the flexible buffer reduces the potential tilting problem of the lower rubber roller 2 caused by the extension and retraction of the first chain 7.

[0033] When the mounting plate is completely removed from the slitting machine, connect the second chains 25 of the left and right bearing roller blocks 6 to the hooks 8 of the other bearing roller block 6 respectively. Loosen the ingot bolts 13 to allow the bearing roller block 6 to be removed from the mounting plate 4. Optionally, lay an inclined plate or use manual handling, jacks, or other methods to bring the casters 23 at the bottom of the bearing roller block to the ground to form rolling support. Magnetically fix the telescopic tie rod 24 on the side of the bearing roller block 6 and extend it to achieve rapid transport of the structure.

[0034] Through its electromechanical-hydraulic integrated design, the organization transforms high-altitude operations that originally required multiple people into ground-based two-person operations, reducing the working time to just half an hour for the entire operation.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
