Description

Technical Field

[0001] The utility model relates to the technical field of printing machines, and more specifically, the utility model relates to an efficient material pressing device for a printing machine. Background Art

[0002] At present, the printing machines on the market include a feeding device, a printing device, a hemming device, a shearing device and a collecting device which are arranged in sequence. At the beginning, the paper is located at the feeding device. The paper is released by the feeding device, conveyed to the printing device for printing, then conveyed to the hemming device for folding, then conveyed to the shearing device for cutting, and finally reaches the collecting device for recycling.

[0003] However, after the existing printed products are printed, in order to avoid the coiling of the materials, the printed products need to be pressed. The traditional method is to directly press with a rigid pressing plate, resulting in a large friction during the conveying process and affecting the transmission efficiency. Therefore, an efficient material pressing device for a printing machine is proposed. Summary of the Utility Model

Slide seats are arranged on the lifting mechanisms on both sides of the connecting block. Each slide seat is slidably connected with the guide rod. Pressing components are installed at the bottom ends of each slide seat and the connecting block.

[0006] By operating the two lifting mechanisms, the height of the supported distance adjusting mechanism and each pressing component can be adjusted, so that the distance between each pressing component and the conveying table can be changed, and thus the pressing adjustment for printed products with different thicknesses can be carried out. At the same time, by operating the distance adjusting mechanism, the two slide seats can be made to drag the pressing components connected to the bottom to approach or move away from each other, so that the width of the common pressing of all the pressing components can be adjusted, and thus the pressing range can be adjusted according to the width of the printed product, so that it can be used for printed products with different widths, thereby improving the practicability of the device. When the pressing component presses down on the printed product, the conveyor belt can move along with the movement of the printed product, thereby reducing the friction force generated by the pressing on the printed product and improving the conveying efficiency of the printed product.

[0021] 1. Through the arrangement of the bracket, rollers and conveyor belt, compared with the prior art, the conveyor belt presses down on the printed matter, and during the conveying process of the printed matter, the conveyor belt can rotate accordingly, thereby reducing the blocking friction force generated by pressing down on the printed matter, thereby improving the transmission efficiency of the printed matter, and thus improving the printing efficiency;

At the same time, by operating the distance adjusting mechanism 4, the two slide seats 7 can be made to drag the pressing components 8 connected to the bottom to approach or move away from each other, so that the width of the common pressing of all the pressing components 8 can be adjusted, and thus the pressing range can be adjusted according to the width of the printed material, so that it can be used for printed materials with different widths, thereby improving the practicality of the device. When the pressing component 8 presses down on the printed material, the conveyor belt 803 can move along with the movement of the printed material, thereby reducing the friction force generated by the pressing on the printed material and improving the conveying efficiency of the printed material.
