Abstract
Description
Technical Field
[0001] This utility model relates to the field of vacuum roller technology, and in particular to a wear-resistant and anti-aging vacuum roller. Background Technology
[0002] Vacuum rollers are widely used in many fields of industrial production, such as printing, papermaking, and plastics processing. However, during long-term use, the surface of vacuum rollers is subject to friction from materials, corrosion from chemicals, and the effects of environmental factors, which gradually damages their wear-resistant and anti-aging layers, thus affecting the performance and service life of the vacuum rollers.
[0003] Traditional vacuum rollers, when replacing the wear-resistant and anti-aging layers, lack a structure for quick installation and replacement. When these protective layers are damaged and require repair, it may be necessary to disassemble a large number of other components to access the roller surface, requiring a complex disassembly process, consuming a lot of time and manpower, and seriously affecting production efficiency. Therefore, we propose a wear-resistant and anti-aging vacuum roller to solve this problem. Utility Model Content
[0004] The purpose of this invention is to provide a wear-resistant and anti-aging vacuum roller to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A wear-resistant and anti-aging vacuum roller includes: a worktable, a fixed plate fixedly installed on the top of the worktable, a rotating shaft rotatably installed inside the fixed plate, a vacuum roller body fixedly installed on the outside of the rotating shaft, a mounting shell sleeved on the outside of the vacuum roller body, an anti-aging layer fixedly installed on the outside of the mounting shell, a wear-resistant layer fixedly installed on the outside of the anti-aging layer, four sets of sliding frames slidably installed inside the vacuum roller body, a moving block slidably installed inside each of the four sets of sliding frames, an insert block fixedly installed on one side of each of the four sets of moving blocks, a moving rod fixedly installed on the other side of each of the four sets of moving blocks, a handle fixedly installed at one end of each of the four sets of moving rods, a locking block fixedly installed on one side of each of the four sets of sliding frames, the four sets of locking blocks movably inserted into the inner wall of the mounting shell, and a return spring fixedly installed on the other side of each of the four sets of sliding frames.
[0007] Preferably, the four sets of insert blocks are movably inserted into the interior of the vacuum roller body, the four sets of insert blocks are slidably installed on one side of the corresponding slide frame, the four sets of moving rods are slidably installed inside the corresponding slide frame, the four sets of moving rods are slidably installed on both sides of the vacuum roller body, and a return spring is sleeved on the outer side of each of the four sets of moving rods. A screw is rotatably installed inside the top of the worktable, and a moving seat is threadedly connected to the outer side of the screw. A moving plate is fixedly installed on the top of the moving seat, and the rotating shaft is engaged in the moving plate.
[0008] Preferably, four sets of slots are provided on the inner wall of the mounting shell, and the four sets of slots are engaged in the corresponding slots. Sealing bushings are provided on both sides of the vacuum roller body, and two sets of sealing bushings are sleeved on the outside of the rotating shaft. A drive motor is fixedly installed on one side of the fixing plate, and one end of the rotating shaft is fixedly installed on the output end of the drive motor.
[0009] Preferably, the vacuum roller body has four sets of rectangular grooves inside, the four sets of sliding frames are slidably installed in the corresponding rectangular grooves, one end of the four sets of return springs is fixedly installed on one side of the corresponding rectangular groove, and the two ends of the four sets of return springs are respectively fixedly installed on one side of the corresponding moving block and one side of the inner wall of the corresponding sliding frame.
[0010] Preferably, the vacuum roller body has four sets of slots inside, and the four sets of inserts are movably inserted into the corresponding slots.
[0011] Preferably, the workbench has two sets of T-slots inside, the two sides of the movable seat are slidably installed in the corresponding T-slots, a turntable is rotatably installed on one side of the workbench, and one end of the screw is fixedly installed on one side of the turntable.
[0012] In this invention, a wear-resistant and anti-aging vacuum roller is provided with stable power to the vacuum roller body by setting a drive motor and a rotating shaft, and a sealing bushing is set to provide a seal between the vacuum roller body and the rotating shaft. This method of directly connecting the drive motor and the rotating shaft can effectively utilize the power.
[0013] In this invention, a wear-resistant and anti-aging vacuum roller is provided. A turntable drives a screw to rotate, and a T-slot restricts the movement of the movable seat, thereby causing the movable plate to detach from the rotating shaft. This provides a reasonable space for installing the anti-aging layer and wear-resistant layer on the outside of the vacuum roller body. Then, the turntable reverses and drives the screw to reverse, causing the movable seat to move the movable plate horizontally. This allows the movable plate to engage with the outside of the rotating shaft, forming a relatively stable support and power structure for the shaft. Operators can more easily adjust the position to ensure that these protective layers can be accurately installed on the roller shaft. The movable plate can also help bear part of the weight, making the installation process safer and easier.
[0014] This utility model features a reasonable structural design. Through the cooperation of the handle, moving rod, moving block, and sliding frame, four sets of insert blocks disengage from the slots, and the first return spring contracts, thereby releasing the displacement restriction on the sliding frame. Then, through the cooperation between the handle, connecting rod, and moving block, the corresponding sliding frames are driven to move relative to each other within the corresponding rectangular grooves. The second return spring contracts, thereby driving the locking block to disengage from the locking groove of the mounting shell. This allows for the quick removal of the aged and worn anti-aging layer, mounting shell, and wear-resistant layer. The four sets of locking grooves on the inner wall of the replaced mounting shell are then aligned with the locking block. Releasing the handle allows each component to reset under the elastic force of the first and second return springs. This enables rapid disassembly and replacement of the anti-aging layer, mounting shell, and wear-resistant layer. This design eliminates the need for complex disassembly of the entire vacuum roller device, significantly shortening maintenance time. It facilitates enterprises in upgrading and transforming vacuum rollers, enabling the timely adoption of more advanced materials and technologies to improve equipment performance and competitiveness without requiring a large-scale replacement of the entire vacuum roller, thus reducing the cost and difficulty of equipment upgrades.

[0021] In this embodiment, four sets of insert blocks 18 are movably inserted into the interior of the vacuum roller body 5. The four sets of insert blocks 18 are slidably installed on one side of the corresponding slide frame 16. The four sets of moving rods 19 are slidably installed inside the corresponding slide frame 16 and on both sides of the vacuum roller body 5. A return spring 20 is sleeved on the outer side of each of the four sets of moving rods 19. A screw 12 is rotatably installed inside the top of the worktable 1. A moving seat 10 is threadedly connected to the outer side of the screw 12. A moving plate 11 is fixedly installed on the top of the moving seat 10. The rotating shaft 4 is snapped into the moving plate 11. This structure can quickly disconnect the vacuum roller body 5 from other components, improving maintenance efficiency.
[0022] In this embodiment, four sets of slots are provided on the inner wall of the mounting shell 7, and four sets of locking blocks 23 are engaged in the corresponding slots. Sealing bushings 6 are provided on both sides of the vacuum roller body 5. Two sets of sealing bushings 6 are sleeved on the outside of the rotating shaft 4. A drive motor 3 is fixedly installed on one side of the fixing plate 2, and one end of the rotating shaft 4 is fixedly installed on the output end of the drive motor 3. This connection method is simple and firm, and can ensure that the mounting shell 7 and the vacuum roller body 5 are tightly connected.
[0023] In this embodiment, four sets of rectangular grooves 15 are provided inside the vacuum roller body 5, and four sets of sliding frames 16 are slidably installed in the corresponding rectangular grooves 15. One end of the four sets of return springs 22 is fixedly installed on one side of the corresponding rectangular groove 15, and the two ends of the four sets of return springs 20 are respectively fixedly installed on one side of the corresponding moving block 17 and one side of the inner wall of the corresponding sliding frame 16, ensuring that the sliding frame 16 can move in a predetermined direction inside the vacuum roller body 5.
[0024] In this embodiment, the vacuum roller body 5 has four sets of slots inside, and four sets of insert blocks 18 are movably inserted into the corresponding slots to ensure the structural integrity of the vacuum roller body 5 and ensure the safe operation of the equipment.
[0025] In this embodiment, the workbench 1 has two sets of T-slots 14 inside. The two sides of the movable seat 10 are slidably installed in the corresponding T-slots 14. A turntable 13 is rotatably installed on one side of the workbench 1. One end of the screw 12 is fixedly installed on one side of the turntable 13. The T-slots provide a stable motion track for the movable seat 10, so that the movable seat 10 can move smoothly under the drive of the screw 12.
[0026] In this embodiment, during use, a drive motor 3 and a rotating shaft 4 provide stable power to the vacuum roller body 5. A sealing bushing 6 provides a seal between the vacuum roller body 5 and the rotating shaft 4. The rotating turntable 13 drives the screw 12 to rotate, thereby causing the moving seat 10 to move horizontally under the restriction of the T-slot 14. This causes the moving plate 11 to disengage from the rotating shaft 4, providing a reasonable space for the installation of the anti-aging layer 8 and the wear-resistant layer 9 on the outside of the vacuum roller body 5. Simultaneously, pulling the two sets of handles 21 on both sides causes the corresponding moving rods 19 and moving blocks 17 to move under the restriction of the slide frame 16, causing the four sets of inserts 18 to disengage from the slots. The return spring 20 contracts, thereby releasing the displacement restriction on the slide frame 16. Then, pulling the two sets of handles 21 on the same side, through the connection The rod and moving block 17 drive the corresponding sliding frame 16 to move relative to each other in the corresponding rectangular groove 15. The second return spring 22 retracts, thereby driving the locking block 23 to disengage from the slot of the mounting shell 7. The aged and worn anti-aging layer 8, mounting shell 7 and wear-resistant layer 9 can be quickly removed. Then, the four sets of slots on the inner wall of the replaced mounting shell 7 are aligned with the locking block 23. The handle 21 is released, and each component is reset under the elastic force of the first return spring 20 and the second return spring 22. This allows for quick disassembly and replacement of the anti-aging layer 8, mounting shell 7 and wear-resistant layer 9. Then, the reverse turntable 13 drives the screw 12 to reverse, causing the moving seat 10 to drive the moving plate 11 to move horizontally. The moving plate 11 is locked on the outside of the rotating shaft 4, forming a relatively stable support and power structure for the rotating shaft 4.
