Description

Technical Field

[0001] The utility model relates to the technical field of printing, in particular to a feeding mechanism for printing. Background Art

[0002] Printing is a technology that allows the original text, pictures, photos, anti-counterfeiting and other manuscripts to be transferred to the surface of paper, textiles, plastics, leather, PVC, PC and other materials through processes such as plate making, inking and pressurization, so as to reproduce the original content in batches. Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink.

[0003] When the existing printing press is in use, it is generally equipped with an automatic feeding mechanism to realize the automatic feeding of the printing substrate. However, when printing on large cardboard or wood board, the traditional automatic feeding mechanism cannot meet the feeding requirements.

[0032] A feeding mechanism for printing, comprising a transport frame 1 and a transport roller 2.

[0033] A plurality of rotating transport rollers 2 are installed inside the transport frame 1;

[0034] A material box 3 and a guide assembly 5 are mounted above the transport frame 1. A plurality of groups of material plates 4 are arranged in the material box 3 and are distributed up and down. A second mounting seat 9 fixedly connected to the transport frame 1 is arranged on one side of the material box 3. A third hydraulic device 10 is mounted above the second mounting seat 9. A push plate 11 is fixedly connected to the free end of the third hydraulic device 10.

[0035] The guide assembly 5 includes a side plate 501, a protective frame 502 and a first hydraulic device 503. The bottom of the side plate 501 is fixedly connected to the transport frame 1.

[0036] The front and rear ends of the filter plate 505 are slidably connected to the side plate 501 .

[0037] The filter plate 505 is arranged at an inclination.

[0038] When the existing printing press is in use, it is generally equipped with an automatic feeding mechanism to realize the automatic feeding of the printing substrate. However, when printing on large cardboard or wood board, the traditional automatic feeding mechanism cannot meet the feeding requirements, and the staff is required to put the large cardboard on the printing press and straighten it. The workers are required to bend back and forth frequently to pick up the cardboard and place it on the printing press, which increases the labor intensity of the workers and poses a serious threat to their health. When the device is used, an external power supply is connected. When feeding a larger substrate, the material plate 4 can be placed flat inside the material box 3. When feeding, the third hydraulic device 10 is started to drive the push plate 11 to move , the push plate 11 extends into the bottom of the material box 3 and pushes out the material plate 4 at the bottom, and transports it to the inside of the guide assembly 5 through the transport roller 2. The setting of the guide assembly 5 can ensure that the transported material plate 4 moves individually, ensuring the subsequent printing quality. When the material plate 4 moves through the transport roller 2, its first hydraulic device 503 starts to drive the moving shaft 504 below to move, and the moving shaft 504 drives the filter plate 505 to move downward, so that the distance between the lowest end of the filter plate 505 and the protective frame 502 is the thickness of a material plate 4, which is convenient for transporting only one material plate 4 at a time. When two or more material plates 4 are transported, the filter plate 505 can be used for the purpose of rejection;

[0039] In this embodiment, the power of the transport roller 2 is provided by a motor, and the filter plate 505 is driven to move through the first hydraulic device 503 above the filter plate 505, so that material plates 4 of different thicknesses can be blocked, thereby expanding the scope of use.
