Description

Technical Field

[0001] This utility model relates to the field of sleeve rubber roller technology, specifically a sleeve rubber roller core clamping and positioning device. Background Technology

[0002] Sleeve rollers are commonly used in industrial production, especially in industries such as printing, packaging, paper processing, and coating. They are made of a roller with a soft rubber material (such as rubber, silicone, or other synthetic rubber) wrapped around its outer surface. The main functions of sleeve rollers are to transmit power, provide contact pressure, or control the movement of materials during the production process.

[0003] Currently, clamping and positioning devices are required when positioning sleeve rubber rollers. However, the current clamping and positioning devices are not convenient for quickly clamping roller cores of different sizes when positioning sleeve rubber rollers, which easily leads to unstable clamping when clamping and positioning roller cores of different sizes.

[0004] Based on this, this utility model designs a sleeve rubber roller core clamping and positioning device to solve the problem. Utility Model Content

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a sleeve rubber roller core clamping and positioning device, including two bases 1, a lifting component 2 inside the two bases 1, a positioning component 3 inside the two bases 1, an installation component 4 above the two bases 1, and a power component 5 inside the two bases 1.

[0023] Please see Figure 1 and Figure 3 The power assembly 5 includes stepper motors 501 respectively mounted on two bases 1 on opposite sides. The inner walls of both bases 1 are provided with cavities 502, and the inner walls of each cavity 502 are provided with through slots 505. The output end of each stepper motor 501 is fixedly mounted with a rotating shaft 508. The opposite sides of the two rotating shafts 508 are fixedly mounted with first gears 507. The inner walls of each cavity 502 are rotatably mounted with rotating rods 503 via bearings. The outer surface of each rotating rod 503 is fixedly mounted with second gears 504. The two sets of second gears 504 mesh with the two first gears 507 respectively. The stepper motors 501 can provide power to the first gears 507, so that the first gears 507 can drive the second gears 504 to rotate, thereby enabling the second gears 504 to provide power to the lifting assembly 2.

[0024] Please see Figure 1 and Figure 2 The lifting assembly 2 includes two sets of sliding openings 201 opened on the upper surface of the two bases 1. Two sliding plates 202 are slidably installed on the inner wall of each sliding opening 201. Two horizontal plates 203 are fixedly installed at the bottom of the two sets of sliding plates 202. A set of toothed grooves 204 are opened on the side of the two sets of sliding plates 202 that are close to each other. The two sets of toothed grooves 204 mesh with two sets of second gears 504 respectively. The meshing action of the toothed grooves 204 and the second gears 504 can control the sliding plate 202 to move up and down, so that the sliding plate 202 can drive the horizontal plate 203 to move up and down.

[0025] Please see Figure 2 The positioning component 3 includes two grooves 301 formed on the bottom surface of the base 1. Two first connecting seats 302 are fixedly installed on the inner wall of each groove 301. Two first rotating wheels 303 are rotatably installed on the inner wall of each first connecting seat 302 through two bearings. Two second connecting seats 304 are fixedly installed on the upper surface of each horizontal plate 203. Two second rotating wheels 305 are rotatably installed on the inner wall of each second connecting seat 304 through two bearings. The first rotating wheels 303 and the second rotating wheels 305 can clamp the roller core in cooperation with the first rotating wheels 303 when the second rotating wheel 305 moves upward, so as to prevent the roller core from becoming loose.

[0026] Please see Figure 1 The mounting component 4 includes two connecting blocks 401 mounted on the upper surfaces of the two bases 1. Each connecting block 401 has a mounting plate 402 fixedly mounted on its upper surface. Each mounting plate 402 has two mounting holes 403 on its upper surface. Through the cooperation of the mounting plate 402 and the mounting holes 403, the mounting holes 403 can fix the device and prevent the device from sliding.

[0027] Please see Figure 1 Each horizontal board 203 has a connecting strip 6 fixedly installed on its front and back sides. The sides of the two connecting strips 6 that are close to each other are fixedly installed on the sides of the two sets of sliding plates 202 that are far apart from each other. The connecting strips 6 can reinforce the horizontal board 203 and prevent the horizontal board 203 from falling off.

[0028] Please see Figure 3 Two reinforcing rings 506 are fixedly installed on the outer surface of each rotating rod 503. The two sets of reinforcing rings 506 are fixedly installed on the left and right sides of the two sets of second gears 504 respectively. The reinforcing rings 506 can reinforce the second gears 504 and prevent the second gears 504 from becoming loose.

[0029] The implementation principle of the sleeve rubber roller core clamping and positioning device in this application embodiment is as follows: In use, the device is installed through the mounting hole 403 and the mounting plate 402. Then, the roller core is placed above the two horizontal plates 203 and in contact with the two sets of second rotating wheels 305. Subsequently, the stepper motor 501 is started, which drives the rotating shaft 508, which in turn drives the first gear 507 to rotate. As the first gear 507 rotates, it drives the second gear 504 to rotate. The second gear 504, through meshing with the tooth groove 204, controls the slide plate 202 to move, thereby causing the slide plate 202 to slide upward along the sliding opening 201. The slide plate 202 drives the horizontal plate 203 to move upward, and the horizontal plate 203 pushes the second rotating wheel 305 to move upward, thereby causing the second rotating wheel 305 to push the roller core to move. In this way, the second rotating wheel 305 cooperates with the first rotating wheel 303 to clamp the roller core and prevent the roller core from loosening.
