Abstract
Description
Technical Field
[0001] This utility model relates to an anti-slip device for the belt of a printing plate making machine, belonging to the technical field of printing plate making machines. Background Technology
[0002] Currently, the printing industry has increasingly higher requirements for the color and registration accuracy of printed materials. Besides manual operation during production, the pre-printing preparation process, specifically the laser printing of PS plates using a plate-making machine, is also crucial for ensuring printing quality. The PS plate is an 1160mm*1040mm, 0.2mm thick aluminum plate with a layer of photosensitive emulsion on its surface. When the PS plate enters the plate-making machine, it is conveyed by a belt. After the laser prints the pattern onto the PS plate, the finished PS plate is mounted on the printing press. The printing press then transfers the patterned area to a metal plate, which is then transferred to a second printing press with a different color ink. This is color registration. The two PS plates must be perfectly aligned to ensure accurate registration of the printed image.
[0003] However, when the PS plate enters the plate-making machine, the belt is subjected to temperature changes and long-term wear during rapid transport, causing it to slip. This results in the PS plate entering the machine at an angle, causing the laser-printed pattern to be skewed, which in turn affects the registration of the printed pattern and thus the printing quality. Therefore, designing an anti-slip device on the plate-making machine belt will effectively prevent the PS plate from skewing, thereby ensuring that the printed pattern is not skewed and guaranteeing the registration accuracy of subsequent printing. Utility Model Content
[0004] The purpose of this invention is to provide a belt anti-slip device for a printing plate-making machine. During the process of the PS plate entering the plate-making machine via the conveyor belt, it helps the PS plate to enter the plate-making machine in a balanced manner, avoids the PS plate from tilting, ensures the quality of subsequent printing registration, and solves the problems existing in the background art.
[0005] The technical solution of this utility model is:
[0006] A printing plate-making machine belt anti-slip device includes a plate-making machine hub, a plate-making machine transmission lever, a plate-making machine table, and a PS plate conveyor belt. The plate-making machine hub is installed inside the plate-making machine. The PS plate is conveyed into the plate-making machine via the PS plate conveyor belt and wrapped around the plate-making machine hub. The PS plate conveyor belt is set on the plate-making machine table. The plate-making machine table is provided with a rubber wheel that is assembled with the PS plate. The rubber wheel is rotatably connected to one end of a bracket. The other end of the bracket is provided with a sleeve that is fitted onto the plate-making machine transmission lever.
[0007] The bracket is L-shaped.
[0008] The bracket consists of two right-angle iron pieces and a fixed wheel. The two right-angle iron pieces are fixedly connected together in the middle by the fixed wheel. The sleeve is fixed to one end of the two right-angle iron pieces, and the rubber wheel is rotatably connected to the other end of the two right-angle iron pieces. The rubber wheel presses on the PS plate.
[0009] The rubber wheel is located on the side of the PS plate conveyor belt near the plate-making machine hub.
[0010] The beneficial effects of this utility model are: during the process of the PS plate entering the plate-making machine via the conveyor belt, it helps the PS plate to enter the plate-making machine in a balanced manner, avoids the PS plate from tilting, thereby improving the accuracy of PS laser printing and ensuring the quality of subsequent printing registration.

[0014] The present invention will be further described below with reference to the accompanying drawings and examples.
[0015] See attached document Figure 1-2 A printing plate-making machine belt anti-slip device includes a plate-making machine hub 1, a plate-making machine transmission lever 2, a plate-making machine table 3, and a PS plate conveyor belt 4. The plate-making machine hub 1 is installed inside the plate-making machine. The PS plate is conveyed to the plate-making machine through the PS plate conveyor belt 4 and wrapped around the plate-making machine hub 1. The PS plate conveyor belt 4 is set on the plate-making machine table 3. The plate-making machine table 3 is provided with a rubber wheel 6 that is assembled with the PS plate. The rubber wheel 6 is rotatably connected to one end of a bracket 5. The other end of the bracket 5 is provided with a sleeve 7, which is fitted onto the plate-making machine transmission lever 2.
[0016] In this embodiment, refer to the appendix Figure 1-2 The device includes a plate-making machine hub 1, a plate-making machine drive screw 2, a plate-making machine table 3, a PS plate conveyor belt 4, a bracket 5, rubber wheels 6, and a sleeve 7, wherein:
[0017] The PS plate conveyor belt 4 is set on the plate-making machine table 3 for conveying the PS plate. The plate-making machine transmission lever 2 is located above the plate-making machine hub 1, which is installed inside the plate-making machine. The PS plate is conveyed into the plate-making machine via the PS plate conveyor belt 4 and wrapped around the plate-making machine hub 1. As the plate-making machine hub 1 rotates, the laser printing device moves from one side to the other to print the pattern on the PS plate.
[0018] The bracket 5 consists of two right-angle iron pieces and a fixed wheel 8. The two right-angle iron pieces are fixedly connected together in the middle by the fixed wheel 8. The fixed wheel 8 does not rotate. The sleeve 7 is fixed to one end of the two right-angle iron pieces. The two right-angle iron pieces can rotate around the transmission screw 2 of the plate-making machine through the sleeve 7. The rubber wheel 6 is rotatably connected to the other end of the two right-angle iron pieces. The rubber wheel 6 presses on the PS plate. The rubber wheel 6 is located on the side of the conveyor belt 4 close to the plate-making machine, so it does not affect the actual operation of the plate-making machine and provides assistance to the PS plate.
