Description

Technical Field

[0001] The utility model relates to plate roller polishing, in particular to a plate roller polishing device before chrome plating. Background Art

[0002] Printing rollers are often used for printing plastic packaging. When producing printing rollers, manufacturers will engrave patterns on their surfaces and then chrome-plate them. Chrome plating can not only improve the wear resistance of the roller surface, making its surface less prone to wear, but also benefit from the stable chemical properties of chromium. The corrosion resistance of the roller is greatly improved after chrome plating, thereby extending the service life of the roller.

[0003] Before chrome plating the printing plate roller, the roller surface needs to be polished to remove the oxide layer, burrs and other contaminants on the surface. The existing polishing method is that the motor drives the plate roller to rotate, and the operator lays sandpaper on one side of the plate roller. During the rotation of the plate roller, the sandpaper polishes the contacted portion of the plate roller. After polishing, the operator manually moves the position of the sandpaper to polish the unpolished portion of the plate roller. Since the sandpaper in this polishing method is simply laid on one side of the plate roller without any fixing measures, it is easy to move with the plate roller during the polishing process, resulting in insufficient and uneven polishing of the plate roller surface. After manually adjusting the position of the sandpaper, the sandpaper needs to be adjusted again to ensure that the sandpaper can fit face to face with the side of the plate roller, which is time-consuming and labor-intensive, and is not conducive to improving work efficiency.

DETAILED DESCRIPTION

[0024] The following will be combined with the attached embodiment of the utility model Figure 1-6 , clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] like Figures 1 to 6 As shown, the utility model discloses a device for polishing a plate roller before chrome plating, comprising an operating table 11, a frame plate 12 is fixedly connected to one side of the operating table 11, a first servo motor 13 is fixedly connected to the outer side of the frame plate 12, a connector 14 is fixedly connected to the output shaft of the first servo motor 13, a transmission screw 15 is rotatably connected to one side of the connector 14 of the frame plate 12, a movable stop plate 16 is threadedly connected to the transmission screw 15, and a rotating head 33 is fixedly connected to the inner side of the movable stop plate 16;

[0027] When installing the plate roller that needs to be polished, first move the movable abutment plate 16 to reserve a certain installation space for the plate roller, then install one end of the plate roller shaft on the connecting head 14, and then drive the movable abutment plate 16 to approach and connect the 33 with the other end of the plate roller shaft. The plate roller is fixed by the above structure and driven to rotate. When the first servo motor 13 drives the plate roller to rotate through the connecting head 14, the other end of the plate roller can rotate relative to the rotating head 33.

[0028] The operating table 11 is rotatably connected to a reciprocating screw 17 on the inner side surface of the frame plate 12, and a grinding seat 18 for polishing the surface of the plate roller is threadedly connected to the reciprocating screw 17. A fixing groove 19 for placing sandpaper is opened in the grinding seat 18, and fixing components for fixing sandpaper are symmetrically arranged in the fixing groove 19.

[0029] The working principle of the utility model is as follows: the operator installs the plate roller between the movable abutment plate 16 and the connecting head 14, and the connecting head 14 drives the plate roller to rotate. During the rotation of the plate roller, the grinding seat 18 performs reciprocating linear motion on the reciprocating screw 17 at any time, so as to evenly grind the outer surface of the plate roller. There is no need for the operator to manually adjust the position of the sandpaper, and the operation is simple, thereby effectively improving the grinding efficiency.

[0030] The specific structure of the fixing assembly is as follows: the fixing assembly includes a stop plate 20 and a first threaded shaft 21;

[0031] The bottom of the grinding seat 18 is provided with a movable groove 22 that penetrates upward and communicates with the fixed groove 19 to provide the movable space required by the first threaded shaft 21. A threaded hole is penetrated through the bottom of the movable groove 22. The first threaded shaft 21 is threadedly connected to the threaded hole. The upper end of the first threaded shaft 21 is rotatably connected to the lower end of the support plate 20.

[0032] The working principle of the fixing assembly is as follows: the operator inserts the two ends of the cut sandpaper into the fixing groove 19 respectively, and then rotates the first threaded shaft 21 to move the support plate 20 upward until it is pressed on the sandpaper, thereby fixing the sandpaper to prevent it from falling off the grinding seat 18 during the polishing process and affecting the polishing efficiency. In addition, a plurality of friction grooves 29 are provided on the upper end surface of the support plate 20 to increase the friction between the support plate 20 and the sandpaper, thereby further fixing the sandpaper.

[0033] Further, in order to prevent sandpaper and to adjust the height of the grinding seat 18 according to the grinding needs of the plate roller, the grinding seat 18 includes a stepless adjustment component, and the specific structure of the stepless adjustment component is: the stepless adjustment component includes a second threaded shaft 23, a rotating bevel gear 24 and a transmission bevel gear 25;

[0034] A sliding seat 26 is provided below the grinding seat 18, and a sliding sleeve 27 is fixedly connected to the sliding seat 26. The second threaded shaft 23 is rotatably connected to the bottom of the sleeve 27. The grinding seat 18 is threadedly connected to the upper end of the second threaded shaft 23. The rotating bevel gear 24 is fixedly connected to the lower end side wall of the second threaded shaft 23. A rotating rod 28 that penetrates and extends into the interior of the sleeve 27 is rotatably connected to the side wall of the sleeve 27. The transmission bevel gear 25 is fixedly connected to one end of the rotating rod 28 located in the sleeve 27, and the transmission bevel gear 25 is meshingly connected to the rotating bevel gear 24.

[0035] The working principle of the stepless adjustment component is: the operator rotates the rotating rod 28, so that the transmission bevel gear 25 drives the rotating bevel gear 24 to rotate, thereby rotating the second threaded shaft 23, and the grinding seat 18 is raised and lowered on the second threaded shaft 23, so that the height of the grinding seat 18 can be accurately adjusted, so that the sandpaper can fit the lower side of the plate roller.

[0036] In addition, flying chips are generated during the grinding process. These flying chips are scattered on the ground, which is inconvenient to clean and may also hurt the operator. Therefore, the operating table 11 is provided with an upward-through collecting groove 30 directly below the sliding seat 26. The lower end of the operating table 11 is fixedly connected to an air pump 31, and the air suction port of the air pump 31 is connected to the collecting groove 30. The flying chips generated by polishing during the operation of the air pump 31 are collected in the collecting groove 30 to prevent the flying chips from splashing.

[0037] In addition, the bottom of the collecting trough 30 is a slope inclined from left to right. When flying chips fall into the collecting trough 30, they will follow the slope and fall to the lowest point of the collecting trough 30 to facilitate the operator to clean the air. The upper end of the air suction port of the air pump 31 is fixedly connected with a filter cloth 32 to prevent flying chips from entering the air pump 31 and causing malfunctions.
