Description

Technical Field

[0001] The utility model relates to the technical field of printing roller polishing, in particular to a surface polishing device for printing rollers. Background Technique

[0002] The surface polishing device for printing rollers is a special equipment used for polishing the surface of printing rollers, which mainly improves the surface finish and flatness of printing rollers, so as to ensure the stability and consistency of printing quality. The working principle of the surface polishing device for printing rollers is mainly based on physical friction and grinding. During the polishing process, the polishing wheel rotates at a high speed driven by a polishing motor and contacts the surface of the printing roller to be polished. Through the relative movement and friction between the polishing wheel and the printing roller, the rough layer and micro defects on the surface of the printing roller are gradually removed, so as to obtain a smoother and flatter surface.

[0003] For the existing surface polishing device for printing rollers, such as a high-precision grinding and polishing device for printing plates disclosed in the publication number CN220660407U, although it has the advantages of being applicable to fixing printing plates with different diameters and improving the applicable range of the device, when polishing the printing plate roller, this polishing device moves from one side of the printing plate roller until the polishing is completed. This polishing method has the problem of low polishing efficiency of the printing plate roller. Therefore, we propose a surface polishing device for printing rollers. Content of the Utility Model

[0023] The following describes a printing roller surface polishing device provided by some embodiments of the present utility model with reference to the accompanying drawings.

[0024] Embodiment 1:

[0025] Combined with Figures 1 - 3 As shown, a printing roller surface polishing device provided by the present utility model includes: a polishing machine 100, a polishing assembly 200, and an adjusting assembly 300; the polishing machine 100 includes a rotator 101 and a presser 102 fixedly installed at both ends thereof, and a printing roller member 103 movably clamped between the rotator 101 and the presser 102; the polishing assembly 200 includes an upper polisher 201 and a lower polisher 202 movably installed on both sides of the upper and lower ends of the printing roller member 103, sliding grooves 203 opened in the side walls at both ends of the polishing machine 100, a mounting frame 204 movably installed in the sliding grooves 203, a dual-axis motor 205 fixedly installed at the center of the mounting frame 204, lead screws 206 fixedly installed on both sides of the dual-axis motor 205, an upper movable frame 207 and a lower movable frame 208 movably installed at the upper ends of the lead screws 206 on both sides of the dual-axis motor 205; first electric push rods 209 are also fixedly installed in the sliding grooves 203, and the front ends of the first electric push rods 209 are fixedly connected to the mounting frame 204. An upper round rod 210 and a lower round rod 211 are also movably installed in the upper movable frame 207 and the lower movable frame 208 respectively, and both ends of the upper round rod 210 and the lower round rod 211 are fixed in the mounting frame 204. The threads of the lead screws 206 on both sides of the dual-axis motor 205 are arranged in opposite directions. The upper movable frame 207 and the lower movable frame 208 have the same structure, and the upper round rod 210 and the lower round rod 211 have the same structure.

[0026] Specifically, the printing roller surface polishing device is a special equipment for polishing the surface of the printing roller, which mainly improves the surface smoothness and flatness of the printing roller, so as to ensure the stability and consistency of the printing quality. In this polishing machine 100, the upper polishing device 201 and the lower polishing device 202 oppositely installed on the upper and lower sides of the front end of the mounting frame 204 can move the upper polishing device 201 and the lower polishing device 202 at the front end of the mounting frame 204 to the upper and lower ends of the printing roller part 103 through the first electric push rod 209 in the sliding groove 203 after installing the printing roller part 103 between the rotator 101 and the presser 102. Thus, the upper polishing device 201 and the lower polishing device 202 driven in reverse by the double-shaft motor 205 can quickly polish from the middle of the printing roller part 103 to both sides, thereby improving the polishing efficiency of the printing roller part 103. At the same time, when replacing the printing roller part 103, the first electric push rod 209 in the sliding groove 203 can also perform quick telescopic movement of the upper polishing device 201 and the lower polishing device 202 to prevent the problem of blocking and affecting the replacement of the printing roller part 103. The upper round rod 210 and the lower round rod 211 respectively installed in the upper movable frame 207 and the lower movable frame 208 are mainly used for restraining the movement of the upper movable frame 207 and the lower movable frame 208.

[0029] Specifically, the upper polishing device 201 and the lower polishing device 202 are installed in the fixed box 301 through the restraint plate 303 at the rear ends, so that the use height of the upper polishing device 201 and the lower polishing device 202 can also be quickly and accurately adjusted through the second electric push rod 302 at the upper end of the fixed box 301, so as to facilitate the adjustment of the upper polishing device 201 and the lower polishing device 202 when polishing printing roller parts 103 of different sizes.

[0030] The working principle and usage process of the present utility model:

[0031] After the printing roller 103 is installed between the rotator 101 and the presser 102 in the polishing machine 100, first start the first electric push rod 209 at the rear end of the chute 203 to drive the mounting bracket 204 to move forward, so as to move the upper polisher 201 and the lower polisher 202 at the front end of the mounting bracket 204 to the upper and lower ends of the printing roller 103. After the upper polisher 201 and the lower polisher 202 are moved to the upper and lower ends of the printing roller 103, the second electric push rod 302 on the fixed box 301 can be started to move the upper polisher 201 and the lower polisher 202 to fit the outer surface of the printing roller 103. After the upper polisher 201 and the lower polisher 202 are adjusted, the rotator 101, the upper polisher 201, the lower polisher 202 and the dual-axis motor 205 can be started to move the upper polisher 201 and the lower polisher 202 outward to both sides when the printing roller 103 rotates, so that the printing roller 103 is polished from the middle to both sides to improve the polishing efficiency.
