Description

Technical Field

[0001] This utility model relates to the field of packaging color printing technology, specifically a pressing device for a color printing machine used in packaging color printing. Background Technology

[0002] Packaging color printing is a technology that uses printing processes to present exquisite patterns, text, and colors onto packaging materials. It is widely used in the packaging of food, daily chemicals, gifts, electronics, and other products. It not only enhances the product's appearance and brand recognition but also strengthens the functionality and premium feel of the packaging through material selection (such as paper, plastic, and metal) and special processes (hot stamping, UV coating, embossing, etc.). A color printing machine is a device that uses multi-color overprinting technology to print color patterns and text with high precision onto materials such as paper, plastic, and metal. It is widely used in packaging, advertising, publishing, and other fields.

[0003] According to a patent published on the China Patent Network, the patent title is: "A Clamping Device for a Color Printing Machine for Packaging Color Printing," patent application number: 202322270954.1. It includes a base, with casters fixedly mounted on the bottom of the base, a conveyor platform fixedly mounted on the top of the base, a conveyor belt arranged inside the conveyor platform, a color printing machine body fixedly mounted on the top of the base, an operation box fixedly mounted on the top of the base, a preheating box fixedly mounted on the left side of the color printing machine body, and an adjustment mechanism inside the operation box. The machine is equipped with a drying mechanism. A pressure roller contacts the packaging paper, and the spring action presses the paper firmly to prevent displacement during subsequent color printing.

A reciprocating sleeve 16 is threadedly connected to the surface of the reciprocating screw 15. A slide rod 17 is fixedly connected to the front of the reciprocating sleeve 16. An L-shaped plate 18 is slidably connected to the front of the slide rod 17. A vertical plate 19 is fixedly connected to the top of the inner side of the reciprocating sleeve 16.

[0037] refer to Figure 4 An inclined block 23 is fixedly connected to the inner side of the front of the L-shaped plate 18, and the inner side of the inclined block 23 is fixedly connected to the vertical plate 5.

[0038] As a technical optimization of this utility model, by setting the inclined block 23, the L-shaped plate 18 can be more firmly connected to the vertical plate 5, preventing the vertical plate 5 from separating from the L-shaped plate 18.

[0043] The working principle and usage process of this utility model are as follows: First, the user starts the motor 6, which drives the gear 7 to rotate and moves the toothed plate 8 downward. Then, when the toothed plate 8 descends, it pushes the compaction plate 13 downward through the longitudinal plate 10, the convex plate 11, and the strip plate 12, so that the material is tightly attached to the conveyor table 2 to prevent displacement during printing. After printing is completed, the motor 6 reverses, the toothed plate 8 rises, the compaction plate 13 is lifted, and the material can continue to be conveyed, achieving the effect of automatic compaction operation. Then, the drying fan 21 is started to air dry the surface of the printed material to prevent ink smudging. The reciprocating screw 15 drives the reciprocating sleeve 16 to move left and right, so that the drying fan 21 blows air evenly along the conveyor table 2 laterally. The slide bar 17 slides in the slide groove 25 of the L-shaped plate 18 to ensure that the blowing mechanism 14 runs smoothly and achieves the effect of rapid air drying of the material.

[0044] In summary, the clamping device of this color printing machine for packaging printing changes the traditional manual operation method. By using a compaction plate 13 to press down on the material on the top of the conveyor table 2, it can automatically clamp the material, increasing the convenience of operation and ensuring the printing quality of the color printing machine.
