Description

Technical Field

[0001] The utility model specifically relates to the technical field of rubber rollers, and more specifically to a rubber roller with a long service life. Background Art

[0002] A rubber roller is a roller-shaped component mainly made of rubber; the rubber roller has a certain elasticity and can deform under pressure, fully fitting with the surface of the contacted object to ensure a good contact effect. High-quality rubber rollers are made of wear-resistant rubber materials, can withstand long-term friction and wear, and extend the service life. During operation, the rubber roller can play a role in shock absorption and noise reduction, reducing the noise and vibration during equipment operation.

[0003] Currently, traditional rubber rollers are made by mixing rubber and additives. In long-term use, the surface of the rubber roller is corroded and bumped, resulting in the rubber roller being unable to effectively complete the work efficiency, so the rubber roller needs to be replaced in time. However, currently, traditional rubber rollers are integrally arranged with the rotating shaft. When replacing the rubber roller, the rotating shaft needs to be replaced simultaneously, which will increase the production cost.

[0004] After retrieval, Chinese Patent Publication No. CN202221598824.X discloses a rubber roller core that is easy to replace; it includes a roller core and a rubber roller body. The roller core is fixedly clamped in the middle of the rubber roller body. The rubber roller body includes fastening bolts, first fixed connection blocks, connection rings, connection clamping columns, and rubber layers. The rubber layer is fixedly connected to the outside of the connection ring. The connection clamping columns are evenly fixedly installed inside the connection ring. The first fixed connection blocks are evenly fixedly connected to the outside of both ends of the connection ring. The fastening bolts are threadedly inserted and rotated at the front ends of the first fixed connection blocks.

[0005] When replacing the rubber roller in the above patent, the inner part of the rubber roller body is clamped and fixed by sliding the connection card slot and the driving connection column. Although this can achieve the replacement effect, during use, axial sliding may occur between the sliding connection card slot and the rubber roller body. When the rubber roller is traction or printing, it will cause the situation of position deviation, and the work efficiency of the rubber roller cannot be effectively guaranteed. Moreover, the two ends of the rubber roller body in the above patent cannot effectively achieve the limiting effect, so when the rubber roller is working, a large working error may occur. Content of the Utility Model

[0006] The purpose of the present utility model is to provide a rubber roller with a long service life. In this structure, the rubber roller body is installed on a stepped shaft. During the installation process, one end of the stepped shaft is inserted into the interior of the rubber roller body, and by squeezing the clamping plate, the clamping and fixing of one end of the rubber roller body are achieved. At this time, the clamping plate at the other end of the stepped shaft is clamped with the limiting plate at the other end of the rubber roller body, and the clamping and fixing of the rubber roller body are realized through the clamping plate. When the length of the rubber roller body changes, the rotating disk is driven to rotate by the screw rod, so as to change the inclination angle of the clamping plate, effectively realizing the distance between the two clamping plates on the stepped shaft and meeting the clamping requirements of the rubber roller body, so as to solve the problems in the above background technology.

[0007] To achieve the above object, the present utility model provides the following technical solutions:

[0008] A rubber roller with a long service life, including a rubber roller body; limiting plates with the same structure are arranged at both ends of the rubber roller body; the interior of the rubber roller body is installed on the surface of a stepped shaft; cavities are arranged inside both ends of the stepped shaft; grooves for installing rods are opened on the first stepped side wall of the stepped shaft; there are multiple such grooves, and an installation rod is fixedly installed inside the end of each groove; a torsion spring is sleeved on the installation rod; the torsion spring is fixedly installed with a clamping plate;

[0009] As a further technical solution of the present utility model, the end of the clamping plate away from the installation rod is in clamping and mating connection with the limiting plate;

[0010] As a further technical solution of the present utility model, a connecting plate is integrally arranged at the bottom of multiple clamping plates; one end of the connecting plate away from the clamping plate is movably installed with a rotating disk through a connecting shaft; the rotating disk is triangularly arranged;

[0011] As a further technical solution of the present utility model, a threaded hole for the screw rod to pass through is opened at the central position of the rotating disk; the screw rod is in threaded connection with the second stepped end of the stepped shaft;

[0012] As a further technical solution of the present utility model, a runner is sleeved on the second stepped surface of the stepped shaft; the runner is movably installed with a support structure;

[0013] Compared with the prior art, the beneficial effects of the present utility model are:

[0014] In the present utility model, during use, one end of the stepped shaft is inserted into the interior of the rubber roller body. During the movement of the stepped shaft, the inner wall of the installation cylinder of the rubber roller body squeezes the clamping plate, causing the clamping plate to enter the groove opened on the stepped shaft until the squeezed clamping plate separates from the rubber roller body. The clamping plate is effectively reset and bounced by the torsion spring. At this time, the clamping plate at the other end of the stepped shaft contacts the limiting plate on the rubber roller body, realizing the clamping and fixing of the rubber roller body;

[0015] In the present utility model, when replacing the rubber roller body, it may be necessary to replace rubber rollers of different lengths. After the replacement is completed, by rotating the screw, the three corners of the rotating disk are moved in the same direction. When the rotating disk rotates, the rotating disk drives the connecting plate to move downward or upward through the connecting shaft. In this way, the inclination angle of the clamping plate and the distance between the two clamping plates are effectively realized, so as to effectively meet the needs of replacing the rubber roller body and ensure the stability of the rubber roller body.

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Please refer to Figures 1-6, in the embodiment of the present utility model, a rubber roller with a long service life includes a rubber roller body 1; both ends of the rubber roller body 1 are provided with limiting plates 4 with the same structure; the rubber roller body 1 is installed on the surface of a stepped shaft 2; both ends of the stepped shaft 2 are provided with cavities inside; a groove for installing a mounting rod 8 is formed on the side wall of the first step of the stepped shaft 2; there are multiple such grooves, and a mounting rod 8 is fixedly installed inside the end of each groove; a torsion spring 7 is sleeved on the mounting rod 8; the torsion spring 7 is fixedly installed with a clamping plate 6;

[0025] One end of the clamping plate 6 away from the mounting rod 8 is in clamping fit connection with the limiting plate 4.

[0026] By adopting the above technical solution, during use, one end of the stepped shaft 2 is inserted into the rubber roller body 1. During the movement of the stepped shaft 2, the inner wall of the installation cylinder of the rubber roller body 1 presses the clamping plate 6, so that the clamping plate 6 enters the groove formed on the stepped shaft 2 until the pressed clamping plate 6 is separated from the rubber roller body 1. The clamping plate 6 is effectively reset and bounced by the torsion spring 7. At this time, the clamping plate 6 at the other end of the stepped shaft 2 contacts the limiting plate 4 on the rubber roller body 1, realizing the clamping and fixing of the rubber roller body 1;

[0027] A connecting plate 9 is integrally provided at the bottom of each of the multiple clamping plates 6; one end of the connecting plate 9 away from the clamping plate 6 is movably installed with a rotating disk 10 through a connecting shaft 11; the rotating disk 10 is triangularly arranged.

[0028] In this embodiment, a threaded hole for the screw rod 5 to pass through is formed at the central position of the rotating disk 10; the screw rod 5 is threadedly connected to the second step end of the stepped shaft 2;

[0029] A runner 3 is sleeved on the second step surface of the stepped shaft 2; the runner 3 is movably installed with a support structure;

[0030] By adopting the above technical solution, when the rubber roller body 1 is replaced, it may be necessary to replace rubber rollers of different lengths. After the replacement is completed, by rotating the screw rod 5, the three corners of the rotating disk 10 are moved in the same direction. When the rotating disk 10 rotates, the rotating disk 10 drives the connecting plate 9 to move downward or upward through the connecting shaft 11, so as to effectively realize the inclination angle of the clamping plate 6 and the distance between two groups of clamping plates 6, thus effectively meeting the needs of replacing the rubber roller body 1 and ensuring the stability of the rubber roller body 1.

[0031] The working principle of the present utility model is as follows: When in use, one end of the stepped shaft 2 is inserted into the inside of the rubber roller body 1. During the movement of the stepped shaft 2, the inner wall of the mounting cylinder of the rubber roller body 1 presses against the clamping plate 6, causing the clamping plate 6 to enter the groove formed on the stepped shaft 2 until the pressed clamping plate 6 separates from the rubber roller body 1. The clamping plate 6 is effectively reset and bounced by the torsion spring 7. At this time, the clamping plate 6 at the other end of the stepped shaft 2 contacts the limiting plate 4 on the rubber roller body 1, realizing the clamping and fixing of the rubber roller body 1.

[0032] When replacing the rubber roller body 1, it may be necessary to replace rubber rollers of different lengths. After the replacement is completed, by rotating the screw 5, the three corners of the rotating disk 10 are moved in the same direction. When the rotating disk 10 rotates, the rotating disk 10 drives the connecting plate 9 to move downward or upward through the connecting shaft 11. In this way, the inclination angle of the clamping plate 6 and the distance between the two groups of clamping plates 6 are effectively realized, thus effectively meeting the need for replacing the rubber roller body 1 and ensuring the stability of the rubber roller body 1.
