Raw paper cutting equipment used before printing of printing machine

Abstract

The invention discloses raw paper cutting equipment used before printing of a printing machine. The raw paper cutting equipment used before printing of the printing machine comprises a machine table, the upper end of the machine table is fixedly connected with an L-shaped first plate, the first plate is provided with a cutting mechanism for cutting raw paper, the cutting mechanism comprises a cutting knife, the machine table is provided with a placing mechanism for leveling and placing the cut raw paper, the placing mechanism comprises two electric push rods fixedly connected to the lower end of the machine table, the movable ends of the two electric push rods are fixedly connected with a movable frame through fixing blocks, the movable frame freely slides on the side wall of the machine table, a driving groove is formed in the inner wall of the movable frame, a driving disc is rotationally connected to the inner wall of the driving groove in a sealed mode, and a first rod is fixedly connected to the side wall of the driving disc. According to the raw paper cutting equipment used before printing of the printing machine, by arranging the placing mechanism, cut hard body paper can be placed after being adsorbed and moved; and the positions, located under the hard body paper, of the hard body paper are consistent each time, so that the hard body paper is kept tidy when collected, and later printing is facilitated.

Description

technical field [0001] The invention relates to the technical field of base paper cutting, in particular to a base paper cutting device for a printing machine before printing. Background technique [0002] Before the hard base paper is printed and produced, it is necessary to cut the hard base paper into a corresponding size before printing. [0003] In the patent "A Base Paper Cutting Equipment for Printing Machines Before Printing" with the application number "201910823301.7", the scheme transports the base paper through the conveyor belt, and then the push plate pushes the base paper to the limit plate for cutting. After cutting, start The electric telescopic rod opens the cutting board, so that the raw paper automatically falls into the collection box for collection. However, there are still shortcomings in this solution: [0004] 1. The base paper is conveyed through the transmission belt and the push plate, and it is not leveled and compacted during the conveyance, so...

AI Technical Summary

Problems solved by technology

[0004] 1. The base paper is conveyed through the transmission belt and the push plate, and it is not leveled and compacted during the conveyance, so that the base paper is easy to wrinkle and pile up after conveying, which will affect the cutting quality of the base paper, especially for hard When the base paper is conveyed, once the surface of the hard base paper is wrinkled, it is difficult to recover, thus affecting its appearance;

[0005] 2. The collection of base paper is to drop the base paper directly into the receiving box, which will easily cause the position of the base paper to shift after falling, making the stacking of multiple base papers uneven, so that it needs to be aligned again after the base paper is taken out. Neat printing, cumbersome operation and low efficiency
