Description

Technical Field

[0001] This utility model relates to the field of loading and unloading platform technology, and in particular to an industrial rubber roller with adjustable width. Background Technology

[0002] Adjustable width industrial rollers are flexible processing components adapted to diverse production needs. Their design centers on dynamic adjustment, enabling rapid adaptation of working width through modular design. This allows for efficient processing of materials of different specifications, flexibly adjusting the effective working range according to substrate thickness or process requirements, effectively reducing equipment downtime and changeover time. These rollers are widely used in packaging printing, papermaking, and textile dyeing, ensuring transmission stability at high speeds while reducing material loss through width adjustment, thus improving overall production efficiency. Their design balances durability and ease of operation, and the surface coating possesses antistatic and wear-resistant properties, adapting to complex conditions such as high temperature and high humidity. They are key functional components for cost reduction and efficiency improvement in modern flexible manufacturing systems.

[0003] In practical use, existing devices often adjust the width of the rubber roller by connecting or disassembling an extension module. However, installing the module is not only cumbersome, but it is also difficult to ensure the stability of the connection after installation. Therefore, an industrial rubber roller with adjustable width is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies where adjusting the width of rubber rollers is often achieved by connecting or disassembling extension modules. However, installing these modules is not only cumbersome but also makes it difficult to ensure the stability of the connection after installation. Therefore, this invention proposes an industrial rubber roller with adjustable width.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An adjustable width industrial rubber roller includes a first rubber roller, a connecting shaft and a mounting pin fixedly connected to one side of the first rubber roller, a limit plate provided on one side of the mounting pin, an expansion module connected to one side of the first rubber roller, an air chamber provided inside the expansion module, a first piston slidably connected inside the air chamber, a connecting pipe fixedly connected to the air chamber, a locking housing fixedly connected to the end of the connecting pipe away from the air chamber, the locking housing fixedly connected inside the expansion module, a second piston slidably connected inside the locking housing, a locking ball provided on the upper part of the second piston, and the locking ball slidably connected to the locking housing.

[0007] When the width of the first and second rubber rollers needs to be adjusted, the connecting shaft and mounting pin are inserted into the expansion module. The connecting shaft drives the first piston to move, thereby compressing the gas inside the air chamber. The gas then enters the locking housing through the connecting pipe. As the air pressure inside the locking housing increases, it drives the locking ball to move. The movement of the second piston causes the locking ball to close inward, thereby locking the mounting pin inserted into the locking housing. This allows the first and second rubber rollers to be quickly installed with the expansion module. The first and second rubber rollers have the same structure, and the length of the expansion module varies. The length of the expansion module can be adjusted and customized according to actual needs.

[0008] The above technical solution further includes:

[0009] The first piston is fixedly connected to a first spring, and an expansion module is fixedly connected to the side of the first spring away from the first piston. The first spring can drive the first piston to reset.

[0010] The second piston is fixedly connected to a second spring, and a locking housing is fixedly connected to the side of the second spring away from the second piston. The second piston can be reset by the second spring.

[0011] A bidirectional cylinder is fixedly installed inside the limiting plate. The bidirectional cylinder drives the limiting plate to move to both sides. The limiting plate is slidably connected to the connecting shaft.

[0012] The first rubber roller has a mounting base at its lower part, a fixed mounting frame is fixedly connected to the upper part of the mounting base, a first motor is provided on the upper part of the fixed mounting frame, and the first rubber roller is provided at the output end of the first motor.

[0013] A cylinder is provided on the upper part of the fixed mounting frame, and a mounting plate is provided at the output end of the cylinder. The mounting plate is rotatably connected to the fixed mounting frame, and a second rubber roller is rotatably connected to the upper part of the mounting plate.

[0014] An adjusting housing is fixedly connected to the upper part of the mounting base. A second motor is provided on one side of the adjusting housing. A threaded rod is provided at the output end of the second motor. A connecting plate is threadedly connected to the threaded rod. A movable mounting bracket is fixedly connected to the upper part of the connecting plate. A limit groove is slidably connected to the lower part of the movable mounting bracket. The limit groove is fixedly connected to the upper part of the mounting base.

[0015] The upper part of the adjusting housing is fixedly connected to a slide rail, and a connecting plate is slidably connected to the upper part of the slide rail. There are two slide rails, and the connecting plate is limited by the slide rails.

[0016] This utility model has the following beneficial effects:

[0017] In this invention, when adjusting the width, the connecting shaft and mounting pin on one side of the first rubber roller can be directly inserted into the expansion module. The connecting shaft drives the first piston to move, and the movement of the first piston drives the gas inside the air chamber to enter the locking housing through the connecting pipe. After the connecting shaft enters the air chamber, the limit plate can be moved to both sides by activating the bidirectional cylinder, thereby fixing the connecting shaft. After the gas enters the locking housing, the air pressure inside the locking housing increases, which drives the second piston to move. The movement of the second piston drives the locking ball to move inward, thereby locking the mounting pin inserted into the locking housing, quickly realizing the installation and fixing of the expansion module and improving the efficiency of width adjustment.

[0018] In this invention, after adjusting the width of the first and second rubber rollers, starting the second motor can drive the threaded rod to rotate. The rotation of the threaded rod can drive the connecting plate to move, and the movement of the connecting plate can drive the movable mounting frame to move, thereby adapting the movable mounting frame to the first and second rubber rollers after the width adjustment, thus improving the effectiveness of the device.

Detailed Implementation

[0027] 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. Example

[0028] like Figures 1-7 As shown, the present invention proposes an adjustable width industrial rubber roller, including a first rubber roller 1. A connecting shaft 16 and a mounting pin 17 are fixedly connected to one side of the first rubber roller 1. A limit plate 18 is provided on one side of the mounting pin 17. An expansion module 6 is connected to one side of the first rubber roller 1. An air chamber 19 is provided inside the expansion module 6. A first piston 21 is slidably connected inside the air chamber 19. A connecting pipe 22 is fixedly connected to the air chamber 19. A locking housing 23 is fixedly connected to the end of the connecting pipe 22 away from the air chamber 19. The locking housing 23 is fixedly connected inside the expansion module 6. A second piston 25 is slidably connected inside the locking housing 23. A locking ball 26 is provided on the upper part of the second spring 24. The locking ball 26 is slidably connected to the locking housing 23.

[0029] When the width of the first rubber roller 1 and the second rubber roller 2 needs to be adjusted, the connecting shaft 16 and the mounting pin 17 are inserted into the expansion module 6. The connecting shaft 16 drives the first piston 21 to move, thereby compressing the gas inside the air chamber 19. The gas then enters the locking housing 23 through the connecting pipe 22. As the air pressure inside the locking housing 23 increases, it drives the locking ball 26 to move. The second piston 25 moves, causing the locking ball 26 to close inward, thereby locking the mounting pin 17 inserted into the locking housing 23. This allows the first rubber roller 1 and the second rubber roller 2 to quickly install the expansion module 6. The first rubber roller 1 and the second rubber roller 2 have the same structure. The length of the expansion module 6 varies and can be adjusted and customized according to actual needs.

[0030] The first piston 21 is fixedly connected to the first spring 20. An expansion module 6 is fixedly connected to the side of the first spring 20 away from the first piston 21. The first piston 21 can be reset by the first spring 20. The second piston 25 is fixedly connected to the second spring 24. A locking housing 23 is fixedly connected to the side of the second spring 24 away from the second piston 25. The second piston 25 can be reset by the second spring 24. A bidirectional cylinder 27 is fixedly installed inside the limiting plate 18. The bidirectional cylinder 27 drives the limiting plate 18 to move to both sides. The limiting plate 18 is slidably connected to the connecting shaft 16.

[0031] In this embodiment, when adjusting the width, the connecting shaft 16 and mounting pin 17 on one side of the first rubber roller 1 can be directly inserted into the expansion module 6. During the insertion of the connecting shaft 16, the first piston 21 can be moved. The movement of the first piston 21 can drive the gas inside the air chamber 19 to enter the locking housing 23 through the connecting pipe 22. At the same time, the movement of the first piston 21 can synchronously drive the first spring 20 to contract. When one end of the connecting shaft 16 enters the air chamber 19, the limit plate 18 can be moved to both sides by activating the bidirectional cylinder 27, thereby fixing the connecting shaft 16. After the gas enters the locking housing 23, the air pressure inside the locking housing 23 increases, thereby driving the second piston 25 to move. Since the second piston 25 has a wedge-shaped structure, the movement of the second piston 25 can compress the locking bead 26 to move inward, thereby locking the mounting pin 17 inserted into the locking housing 23. This can quickly realize the installation and fixation of the expansion module 6, effectively improving the width adjustment efficiency.

[0032] When the expansion module 6 needs to be disassembled, it is only necessary to control the bidirectional cylinder 27 to move the limiting plate 18 inward to close, thereby allowing the connecting shaft 16 to resume insertion and removal. After the connecting shaft 16 is pulled out, the retracted connecting tube 22 returns to its original shape, which can drive the first piston 21 to reset. At the same time, the second spring 24 inside the locking housing 23 also returns to its original state, thereby relieving the pressure of the second piston 25 on the locking ball 26, so that the mounting pin 17 and the bidirectional cylinder 27 can resume insertion and removal at the same time, which facilitates disassembly and improves the use effect of the device.

[0033] like Figures 1-7 As shown, a mounting base 3 is provided at the lower part of the first rubber roller 1, a fixed mounting frame 4 is fixedly connected to the upper part of the mounting base 3, a first motor 5 is provided on the upper part of the fixed mounting frame 4, the first rubber roller 1 is provided at the output end of the first motor 5, a cylinder 11 is provided on the upper part of the fixed mounting frame 4, a mounting plate 12 is provided at the output end of the cylinder 11, the mounting plate 12 is rotatably connected to the fixed mounting frame 4, and a second rubber roller 2 is rotatably connected to the upper part of the mounting plate 12.

[0034] An adjusting housing 9 is fixedly connected to the upper part of the mounting base 3. A second motor 13 is provided on one side of the adjusting housing 9. A threaded rod 10 is provided at the output end of the second motor 13. A connecting plate 14 is threadedly connected to the threaded rod 10. A movable mounting bracket 8 is fixedly connected to the upper part of the connecting plate 14. A limit groove 7 is slidably connected to the lower part of the movable mounting bracket 8. The limit groove 7 is fixedly connected to the upper part of the mounting base 3. A slide rail 15 is fixedly connected to the upper part of the adjusting housing 9. The connecting plate 14 is slidably connected to the upper part of the slide rail 15. There are two slide rails 15, which limit the connection plate 14.

[0035] In this embodiment, after adjusting the width of the first rubber roller 1 and the second rubber roller 2, starting the second motor 13 can drive the threaded rod 10 to rotate. The rotation of the threaded rod 10 can drive the threaded connecting plate 14 to move. During the movement of the connecting plate 14, the slide rail 15 at the lower part can limit the movement of the connecting plate 14, thereby improving the stability of the connecting plate 14 during movement. The movement of the connecting plate 14 can drive the fixedly connected movable mounting frame 8 to move, so that the movable mounting frame 8 can adapt to the first rubber roller 1 and the second rubber roller 2 after the width adjustment, improving the use effect of the device. During use, starting the cylinder 11 can also drive the mounting plate 12 to rotate. By driving the mounting plate 12 to rotate, the distance between the first rubber roller 1 and the second rubber roller 2 can be adjusted.
