A printing plate transport assembly with automatic positioning function

Abstract

This utility model relates to a printing plate conveying assembly with automatic positioning function, effectively solving the problem of the lack of positioning structure in printing plate conveying. The solution includes a conveyor belt and a limiting unit. The conveyor belt is horizontally arranged, and the limiting unit is located above the conveyor belt and fixed. The limiting unit is a vertical structure with a left-right orientation, and its vertical surface can be abutted by one side of the printing plate. The centerline of the conveyor belt forms an angle with the direction of the limiting unit, and the closer the limiting unit is to the downstream end of the conveyor belt, the closer it is to the centerline of the conveyor belt. When placing the printing plate on the conveyor belt, this utility model does not require active adjustment of the printing plate position or positioning of the printing plate. During the conveying process, the printing plate can be automatically positioned by the limiting unit set at an angle to the conveyor belt, and under the action of the component force, it always maintains abutment with the limiting unit, ensuring that the printing plate is conveyed to the accurate position.

Description

Technical Field

[0001] This utility model relates to the field of printing equipment, specifically a printing plate conveying component with automatic positioning function. Background Technology

[0002] In the printing process, whether it is feeding the printing plate into the plate-making equipment, changing the printing plate between different processes, or feeding the printing plate into the printing press, the printing plate needs to be transported. Currently, the printing plate is generally transported by conveyor belts. The utility model patent with application number: 201720711041.0 uses multiple sets of conveyor belts arranged side by side to transport the printing plate. During the transport process, the printing plate lacks the necessary positioning structure, and the printing plate is prone to skewing and misalignment, which will result in the printing plate not being accurately transported to the required station. Summary of the Invention

[0003] This invention provides a printing plate conveying assembly with automatic positioning function, aiming to solve the problem of the lack of positioning structure in printing plate conveying.

[0004] The technical solution includes a conveyor belt and a limiting unit. The conveyor belt is set horizontally, and the limiting unit is located above the conveyor belt and is fixed. The limiting unit is a vertical structure that runs left and right. Its vertical surface can be abutted by one side of the printing plate. The center line of the conveyor belt is at an angle to the direction of the limiting unit, and the closer to the downstream end of the conveyor belt, the closer the limiting unit is to the center line of the conveyor belt.

[0005] The limiting unit includes a vertically placed limiting plate, with the side of the printing plate abutting against the surface of the limiting plate for positioning.

[0006] The limiting unit includes several vertical rollers arranged at equal intervals along the left and right directions. The upper ends of all rollers are rotatably mounted on a fixed plate, and the side of the printing plate is positioned against the outer wall of the rollers.

[0007] The lower end of the limiting plate is higher than the surface of the conveyor belt, so that the limiting plate is suspended above the conveyor belt.

[0008] The lower end of the roller is higher than the surface of the conveyor belt, so that the roller is suspended above the conveyor belt.

[0009] The conveyor belt has several support bars fixed at equal intervals on its surface. The printing plate is placed on the support bars so that it is higher than the lower end of the limiting unit.

[0010] Each side of the conveyor belt is equipped with several limit wheels.

[0011] When placing the printing plate on the conveyor belt, this invention eliminates the need for active adjustment or positioning of the printing plate. During the conveying process, the printing plate is automatically positioned by a limiting unit set at an angle to the conveyor belt. Moreover, under the action of the component force, the printing plate always remains in contact with the limiting unit, ensuring that the printing plate is conveyed to the accurate position.

[0016] Referring to the accompanying drawings, this utility model includes a conveyor belt 1 and a limiting unit. The conveyor belt 1 is horizontally arranged, and the limiting unit is located above the conveyor belt 1 and fixed. The limiting unit can be fixed on the frame of the conveyor belt 1 or fixed to the ground. The limiting unit is a vertical structure with a left-right orientation, and its vertical surface can be abutted by one side of the printing plate. The center line of the conveyor belt 1 forms an angle with the orientation of the limiting unit, and the closer to the downstream end of the conveyor belt 1, the closer the limiting unit is to the center line of the conveyor belt 1. When the printing plate is conveyed on the conveyor belt 1, the conveyor belt 1 exerts a component force on the printing plate toward the limiting unit, and one side of the printing plate abuts against the limiting unit to position the printing plate.

[0017] The limiting unit includes a vertically placed limiting plate 2, with the side of the printing plate abutting against the surface of the limiting plate 2 for positioning. The limiting plate 2 is fixed to the frame of the conveyor belt 1 by several connecting rods.

[0018] The limiting unit includes several vertical rollers 3 arranged at equal intervals along the left and right directions. The upper ends of all rollers 3 are rotatably mounted on a fixed plate 4. The fixed plate 4 is fixed to the frame of the conveyor belt 1 by several connecting rods. The side of the printing plate is positioned against the outer wall of the roller 3. The roller 3 can reduce the friction between itself and the printing plate.

[0019] The lower end of the limiting plate 2 is higher than the surface of the conveyor belt 1, so that the limiting plate 2 is suspended above the conveyor belt 1, thus avoiding friction between the limiting plate 2 and the conveyor belt 1.

[0020] The lower end of the roller 3 is higher than the surface of the conveyor belt 1, so that the roller 3 is suspended above the conveyor belt 1, thus avoiding friction between the roller 3 and the conveyor belt 1.

[0021] A number of support bars 5 are fixed at equal intervals on the surface of the conveyor belt 1. The printing plate is placed on the support bars 5 so that the printing plate is higher than the lower end of the limiting unit, thus preventing the printing plate from getting stuck in the gap between the lower end of the limiting unit and the conveyor belt 1.

[0022] Each side of the conveyor belt 1 is provided with several limit wheels 6 to prevent the conveyor belt 1 from running off-center.

[0023] When this utility model is in use, the conveyor belt 1 is started, and the printing plate is placed on the conveyor belt 1 and moves with the conveyor belt 1. Since there is an angle between the movement direction of the conveyor belt 1 and the limiting unit, the printing plate will gradually approach the limiting unit. Finally, one side of the printing plate is in contact with the limiting plate 2 or roller 3 of the limiting unit. Under the force of the conveyor belt 1 on the printing plate towards the limiting unit, the printing plate is always in contact with the limiting unit, so that the printing plate is conveyed to the right end along the limiting unit, thereby allowing the printing plate to accurately enter the plate inlet of the plate making machine or printing machine.

[0024] During the conveying process, this utility model can automatically complete the positioning and holding of the printing plate, ensuring that the printing plate is conveyed to the accurate position.
