One-pass sheet-fed printing device for processing finished products and work method thereof

Abstract

The invention relates to a one-pass sheet-fed printing device for processing finished products, which comprises a sheet conveying unit, a heat printing control unit, a die cutting unit, a waste edge removal unit, a finished product clearing unit, a waste removal unit, a gripper bar and a gripper bar chain. The work method of the one-pass sheet-fed printing device comprises the following steps of: conveying the single sheets to the heat printing control unit by the sheet conveying unit and clamping the sheets by the gripper bar; conveying the single sheets to the heat printing control unit by the gripper bar to finish the heat printing operation or the impressing operation; conveying the sheets to the die cutting unit and finishing the die cutting operation; conveying the sheets to the waste edge removal unit to remove the partial waste edges; conveying the sheets to the finished product clearing unit by the gripper bar to obtain the finished product; and conveying the final waste edge to the waste removal unit. The invention has the advantages of integrating the work of a plurality of devices to one device, reducing of the paper feeding times, improving the production efficiency, reducing the number of workers, lowering the labor cost, avoiding the inaccurate registering precision of the repeated positioning operation caused by the multiple feeding operations, improving the processing quality, decreasing the reject rate and reducing the consumption.

Description

(1) Technical field: [0001] The present invention relates to an automatic printing device and its working method, especially suitable for a kind of printing device and its working method which can complete all the processing steps by feeding paper (single sheet material) and finally get the finished product (sheet box type) at one time, that is, a Printing equipment and its working method for completing finished product processing in one pass. (two) background technology: [0002] With the rapid development of the printing and packaging industry, the market has higher and higher requirements for the automation of post-press processing equipment. The pursuit of high-speed and precise processing equipment to improve production efficiency and occupy the market is the market demand and the inevitable trend of post-press equipment development. . [0003] The existing multi-unit die-cutting hot stamping equipment in the market (refer to the patent ZL200410093700.6 applied by our ...

Problems solved by technology

Apparently, this model can’t meet the market demand of getting finished products in one pass.

[0005] To sum up, none of the existing technologies in the market can meet the requirements of completing one paper feeding, hot stamping (one or two times), die cutting, waste edge removal, finished product cleaning, and waste material removal on the same equipment to obtain finished products (sheet box type) function
