Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of rubber roller preparation equipment, specifically a roller coating device for rubber roller production. Background Technology
[0002] Rubber rollers are generally composed of an outer rubber layer, a hard rubber layer, a metal core, a roller neck, and ventilation holes. Their processing includes roller core sandblasting, bonding treatment, rubber forming, cloth wrapping, wire winding, vulcanization in a vulcanizing tank, and surface finishing.
[0003] In the production of rubber rollers, a protective film is typically wrapped around the outside of the roller. A roller is usually attached to the outside of the roller, and as the roller rotates, it pulls the rubber material to adhere to the outside of the roller. The roller also limits the coating of the roller to ensure that the protective film remains tight during the coating process. However, the diameter and thickness of the rubber roller change with the coating. As the coating continues, the pressure between the rubber roller and the roller increases. This increased pressure can cause the position of the rubber roller and the roller to shift due to compression, thus affecting the coating efficiency. Therefore, we propose a roller coating device for rubber roller production. Utility Model Content
[0004] To address the shortcomings of existing roller coating equipment for rubber roller production, this utility model provides a roller coating equipment for rubber roller production. It features a first adjusting plate and a second adjusting plate that drive the roller to be fitted and installed on the outside of the rubber roller. At the same time, when the thickness of the rubber roller changes, the first adjusting plate and the second adjusting plate are subjected to pressure and move outward to ensure that the coating remains tight. This solves the problems mentioned in the background art.
[0005] This utility model provides the following technical solution: a roller coating device for producing rubber rollers, including a mounting base, a rotating base movably sleeved on one side of the mounting base, an L-plate movably sleeved at the front end of the rotating base, an upper pressure plate movably sleeved on the outside of the L-plate, a second motor mounted on one side of the L-plate, a first limiting mechanism for limiting the angle of the L-plate mounted inside the rotating base, a limiting sleeve fixedly connected to the upper part of the mounting base and located on one side of the rubber roller, a bracket movably sleeved inside the limiting sleeve, a clamping sleeve fixedly connected to the front end of the bracket, a first adjusting plate and a second adjusting plate movably sleeved sequentially on both sides inside the clamping sleeve, a roller mounted inside both the first adjusting plate and the second adjusting plate, and a second limiting mechanism mounted on the top of the roller.
[0006] Preferably, a first motor is mounted on the lower end of the mounting base, a first gear is fixedly connected to the lower end of the mounting base, a second gear is mounted on one end of the output shaft of the first motor, and a rack and pinion chain is sleeved on the outside of the first gear and the second gear.
[0007] Preferably, the first limiting mechanism includes a sealing sleeve, which is fixedly connected to one side of the rotating seat. A positioning pin is installed inside the sealing sleeve by a second spring. The positioning pin passes through the rotating seat. An installation groove is provided on the outside of the L plate and aligned with the positioning pin. The end of the positioning pin is movably sleeved inside the installation groove.
[0008] Preferably, the second limiting mechanism includes a first pulley and a third pulley. The first pulley is fixedly connected to the outside of the roller mounted inside the first adjusting plate, and the third pulley is fixedly connected to the outside of the roller mounted inside the second adjusting plate. A second pulley and a fourth pulley are mounted outside the connection between the first adjusting plate and the second adjusting plate. The first pulley and the second pulley are on the same horizontal plane. A first belt is sleeved on the outside of the first pulley and the second pulley. The third pulley and the fourth pulley are on the same plane, and a second belt is sleeved on the outside of the third pulley and the fourth pulley.
[0009] Preferably, a first lead screw for adjusting the height of the upper pressure plate is installed on the back of the L-plate, and an installation sleeve is installed at the alignment point of the L-plate and the upper pressure plate. A clamping plate is installed on the inner side of the installation sleeve, and a rubber roller is clamped on the inner side of the clamping plate.
[0010] Preferably, a second lead screw is installed inside the limiting sleeve, and the second lead screw is threadedly connected to the lower end of the bracket.
[0011] Preferably, the first adjusting plate is sleeved inside the second adjusting plate, and a first spring is installed on both sides of the first adjusting plate and the second adjusting plate.
[0012] Compared with existing roller coating equipment for rubber roller production, this utility model has the following advantages:
[0013] 1. The roller coating equipment for producing rubber rollers uses a first motor to drive a rotating seat to rotate, which in turn causes the rubber roller to shift off the coating area. At the same time, a second motor is started, which drives an L-plate to rotate. The L-plate rotates and moves the rubber roller to a horizontal parallel state. After adjusting the upper pressure plate to move to the side, the rubber roller can automatically slide down, thereby improving the convenience of unloading by the second motor.
[0014] 2. The roller coating equipment for producing rubber rollers moves towards the rubber roller via a control bracket. Simultaneously, the first and second adjusting plates drive two sets of rollers to press against both sides of the rubber roller. Depending on the width of the rubber roller, the first and second adjusting plates drive the rollers to deflect downwards to both sides. Under the elasticity of the first spring, both sets of rollers can be driven to press against the outside of the rubber roller. At the same time, when the angle of the two sets of rollers deviates, the second limiting mechanism can drive the two sets of rollers to rotate synchronously, ensuring that the coating material maintains tightness when pressing against the outside of the rubber roller.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.
[0022] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 A roller coating device for producing rubber rollers includes a mounting base 1, a rotating base 2 movably sleeved on one side of the mounting base 1, an L-plate 5 movably sleeved at the front end of the rotating base 2, an upper pressure plate 6 movably sleeved on the outside of the L-plate 5, a second motor 11 mounted on one side of the L-plate 5, a first limiting mechanism 12 for limiting the angle of the L-plate 5 mounted inside the rotating base 2, a limiting sleeve 13 fixedly connected to the upper part of the mounting base 1 and located on one side of the rubber roller 10, a bracket 15 movably sleeved inside the limiting sleeve 13, a clamping sleeve 16 fixedly connected to the front end of the bracket 15, a first adjusting plate 17 and a second adjusting plate 18 movably sleeved on both sides inside the clamping sleeve 16, a roller 19 mounted inside both the first adjusting plate 17 and the second adjusting plate 18, and a second limiting mechanism 21 mounted on the top of the roller 19.
[0023] Please see Figure 2 A first motor 3 is installed at the lower end of the mounting base 1, and a first gear is fixedly connected to the lower end of the mounting base 1. A second gear is installed at one end of the output shaft of the first motor 3. A rack chain 4 is sleeved on the outside of the first gear and the second gear. By starting the first motor 3, the first motor 3 drives the rack chain 4 to rotate. After the rack chain 4 rotates, it can drive the L plate 5 to rotate. Rotating the L plate 5 can drive the rubber roller to leave the coating area. After the rubber roller coating is completed, the coating device is prevented from interfering with the feeding of the rubber roller.
[0024] Please see Figure 5 The first limiting mechanism 12 includes a sealing sleeve 121, which is fixedly connected to one side of the rotating seat 2. A positioning pin 123 is installed inside the sealing sleeve 121 through a second spring 122. The positioning pin 123 passes through the rotating seat 2. An installation groove 124 is provided on the outside of the L plate 5 and aligned with the positioning pin 123. The end of the positioning pin 123 is movably sleeved inside the installation groove 124. By starting the second motor 11, the second motor 11 drives the angle of the L plate 5 to be adjusted, thereby driving the rubber roller 10 to be placed laterally, thereby improving the convenience of the rubber roller unloading. At the same time, during the angle adjustment of the L plate 5, the positioning pin 123 disengages from the inside of the installation groove 124, and then the L plate 5 can rotate. When the positioning pin 123 is engaged inside the installation groove 124 under the elastic action of the second spring 122, the angle of the L plate 5 at the front end of the rotating seat 2 is limited.
[0025] Please see Figure 4The second limiting mechanism 21 includes a first pulley 211 and a third pulley 214. The first pulley 211 is fixedly connected to the outside of the roller 19 mounted inside the first adjusting plate 17, and the third pulley 214 is fixedly connected to the outside of the roller 19 mounted inside the second adjusting plate 18. A second pulley 213 and a fourth pulley 216 are mounted on the outside of the connection between the first adjusting plate 17 and the second adjusting plate 18. The first pulley 211 and the second pulley 213 are on the same horizontal plane. A first belt 212 is sleeved on the outside of the first pulley 211 and the second pulley 213. The third pulley 214 and the fourth pulley 216 are on the same plane. The third pulley 214 and the fourth pulley 216 are externally fitted with a second belt 215. The first pulley 211 and the third pulley 214 are sequentially installed on the outside of the two sets of rollers 19. At the same time, the first pulley 211 and the second belt 215 are externally fitted on the second pulley 213 and the fourth pulley 216. When the drive device controls the second pulley 213 to rotate, it can drive the two sets of rollers 19 to rotate synchronously. Meanwhile, the first adjusting plate 17 and the second adjusting plate 18 are cross-installed inside the clamping sleeve 16. Then, during the rotation of the two sets of rollers 19, the second belt 215 and the first belt 212 can both drive the rollers 19 to rotate synchronously.
[0026] Please see Figure 3 The back of L-plate 5 is equipped with a first lead screw 7 for adjusting the height of the upper pressure plate 6. Mounting sleeves 8 are installed at the alignment points of L-plate 5 and upper pressure plate 6. A clamping plate 9 is installed on the inner side of the mounting sleeve 8. A rubber roller 10 is clamped on the inner side of the clamping plate 9. By activating the first lead screw 7, the first lead screw 7 drives the upper pressure plate 6 to adjust its height inside L-plate 5. At the same time, the mounting sleeve 8 and clamping plate 9 are installed between L-plate 5 and upper pressure plate 6, controlling the rubber roller 10 to be installed inside the mounting sleeve 8. That is, the mounting sleeve 8 drives the clamping plate 9 to squeeze and limit rubber rollers 10 of different sizes, ensuring that the rubber roller 10 maintains stability when positioned.
[0027] Please see Figure 1 The limiting sleeve 13 is equipped with a second lead screw 14, which is threadedly connected to the lower end of the bracket 15. By activating the second lead screw 14, the bracket 15 moves inside the limiting sleeve 13. At the same time, the bracket 15 moves the roller 19 to the side of the rubber roller 10, controlling the roller 19 to squeeze and limit the rubber roller 10. When the roller 19 rotates, it can carry the rubber roller 10 to rotate synchronously. When the rubber roller 10 rotates, it can drive the covering device to be sleeved on the outside of the rubber roller 10. At the same time, the roller 19 limits the packaging equipment covering the outside of the rubber roller 10, improving the neatness of the packaging outside the roller 19.
[0028] Please see Figure 4The first adjusting plate 17 is sleeved inside the second adjusting plate 18. The first adjusting plate 17 and the second adjusting plate 18 are each equipped with a first spring 20. The first adjusting plate 17 and the second adjusting plate 18 are installed inside the clamping sleeve 16. After the first adjusting plate 17 and the second adjusting plate 18 drive the roller 19 to press against the outside of the rubber roller 10, the first adjusting plate 17 and the second adjusting plate 18 are simultaneously pressured and move outward. At the same time, the first spring 20 pushes the roller 19 to continuously press against the rubber roller 10, ensuring that the roller 19 is fitted against the outside of the rubber roller 10.
[0029] Working principle: In use, the rubber roller 10 is installed inside the mounting sleeve 8. The clamping plate 9 limits the position of the rubber roller 10. Simultaneously, the first lead screw 7 is activated, pushing the upper pressure plate 6 downward. That is, the upper pressure plate 6, carrying the upper mounting sleeve 8, presses and limits the position of the rubber roller 10. At the same time, the second lead screw 14 is activated, pushing the bracket 15 inward. Simultaneously, the clamping sleeve 16 carries the rollers 19 and presses them against both sides of the rubber roller 10. According to the different thicknesses of the rubber roller 10, the two sets of rollers 19 move to both sides under pressure. At the same time, the second limiting mechanism 21 drives the rollers 19 to rotate synchronously. When the rollers 19 rotate, the rollers... The roller 19 drives the rubber roller 10 to rotate synchronously, which can coat the outside of the roller 19. The two sets of rollers 19 are pressed against the outside of the rubber roller 10, which improves the tightness of the coating device when it is attached to the outside of the rubber roller 10. After the coating is completed, the second lead screw 14 is started, which drives the bracket 15 to move to the initial state. The first motor 3 is started, which drives the rotating seat 2 to rotate. At the same time, the rotating seat 2 drives the rubber roller 10 to move to the side and rotates the second motor 11. The second motor 11 drives the L plate 5 to flip, and then the rubber roller 10 is placed horizontally. At the same time, when the upper pressure plate 6 is controlled to move to the rear end, the rubber roller 10 can automatically slide down for processing, which improves the convenience of unloading the rubber roller 10.
