Printing processing device for konjac packaging food bag

Abstract

The invention relates to the technical field of printing and discloses a printing processing device for a konjac packaging food bag. The printing processing device comprises a discharge roller and a winding roller, wherein a printing box is arranged between the discharge roller and the winding roller; two sides of the printing box are open, an electrostatic eliminating mechanism, a dust removing mechanism, a roller brushing mechanism and a drying mechanism are sequentially arranged in the printing box; the electrostatic eliminating mechanism comprises a supporting roller and a plurality of electrostatic eliminating shafts, the supporting roller is fixed on side walls of the printing box, the electrostatic eliminating shafts are located above the supporting roller and fixedly connected withthe printing box, and the electrostatic eliminating shafts are grounded through the printing box; and the dust removing mechanism comprises an upper roller, a lower roller and a dust removing rollerthrough which the upper roller and the lower roller are rotationally connected with the printing box, cavities are formed in the upper roller and the lower roller, a plurality of grooves distributed in the circumferential direction are formed in outer side walls of the upper roller and the lower roller and communicate with the cavities, and the upper roller and the lower roller communicate with afirst pump assembly and a second pump assembly respectively. The printing processing device is simple in structure, performs dust removing and other processes when printing the packaging bag and improves a printing effect.

Description

technical field [0001] The invention relates to the technical field of printing, in particular to a printing and processing device for konjac packaged food bags. Background technique [0002] Konjac packaging food bags are used to pack konjac to facilitate the transportation of konjac. Corresponding marking patterns are generally printed on konjac packaging food bags, such as: konjac graphics, trademarks, etc. [0003] Nowadays, the printing of marking patterns generally adopts roller printing. During the printing process, since the printing substrates are mostly insulating materials such as paper and plastic, static electricity is easily generated and cannot be dissipated. The ink itself is also charged with static electricity. With the accumulation of charges, It will cause a series of electrostatic faults, which are manifested in the following aspects: static mottle phenomenon, which mainly occurs when printing polyolefin film, and some irregular patterns are formed in l...

[0003] Nowadays, the printing of marking patterns generally adopts roller printing. During the printing process, since the printing substrates are mostly insulating materials such as paper and plastic, static electricity is easily generated and cannot be dissipated. The ink itself is also charged with static electricity. With the accumulation of charges, It will cause a series of electrostatic faults, which are manifested in the following aspects: static mottling phenomenon, which mainly occurs when printing polyolefin films, and some irregular patterns are formed in large-area pattern parts; static burr phenomenon, which appears linear around the drawn line "beard"; electrostatic repulsion leakage phenomenon, such as gaps caused by repulsion when white ink is laid around some characters; electrostatic dust absorption phenomenon, absorbing dust and impurities in the air, reducing the transfer rate of ink, and appearing spots on graphics ;Electrostatic dust absorption phenomenon, absorbing dust and impurities in the air, reducing the transfer rate of ink, and appearing spots on graphics

[0004] To sum up, static electricity on the printing substrate will lead to a serious decline in the printing effect, but in the actual operation, the operator often ignores this problem. In order to improve the printing effect, the printing processing device should be improved
