High-stability wet tissue packaging machine

Abstract

The invention discloses a high-stability wet tissue packaging machine which comprises a wet tissue cutting, folding and pressing-in mechanism and a vertical sealing mechanism. The wet tissue cutting,folding and pressing-in mechanism comprises a cutting knife and a folding insertion piece; the cutting knife is connected with a cutting air cylinder; the folding insertion piece is in transmission connection with a first servo motor; the packaging bag vertical sealing mechanism comprises a mounting base; a front moving frame set and a rear moving frame set are movably arranged on the mounting base; the front moving frame set is connected with a first horizontal driving assembly; the rear moving frame set is connected with a second horizontal driving assembly; the front moving frame set is provided with a first front heat sealing plate and a second front heat sealing plate which are arranged in a matched mode; and the rear moving frame set is provided with a first rear heat sealing plate and a second rear heat sealing plate which are arranged in a matched mode. The high-stability wet tissue packaging machine provided by the invention is simple in structure and reasonable in design, thedistance between the two heat sealing plate sets and the center distance between the heat sealing plate sets and the wet tissue cutting, folding and pressing-in mechanism can be conveniently adjustedaccording to the specifications of wet tissues, and meanwhile, the working stability of the die-cutting, folding and pressing-in mechanism is guaranteed.

[0002] The wet wipe packaging machine is a kind of equipment specially used for wet wipe packaging, and the wet wipe cutting and folding press-in mechanism, the vertical sealing mechanism and the wet wipe unrolling and folding mechanism are important components of the wet wipe packaging machine and the vertical sealing mechanism It is mainly used for vertical heat sealing of wet tissue packaging bags. The traditional vertical sealing mechanism mainly includes a front heat sealing plate group and a rear heat sealing plate group. The front heat sealing plate group is fixed and cannot be horizontally The rear heat-sealing plate group can move horizontally back and forth, and the gap between the front and rear heat-sealing plate groups can be adjusted according to the specifications of the packaging bag, and then the front and rear ends of the packaging bag can be vertically heat-sealed. The defects of the structure are: 1. Since the front and rear positions of the front heat-sealing plate group cannot be changed, the vertical sealing mechanism can only adjust the distance between the front and rear heat-sealing plate groups according to the specifications of the packaging bag, but cannot adjust the vertical sealing mechanism and the middle packaging. The center distance between the bag and the subsequent folding and cutting parts may cause wrinkles and deformation of the packaging bag, affecting the smoothness and stability of the wet wipes packaging; 2. The half-folding insert of the traditional wet wipes cutting and folding press-in mechanism Its action is driven by the cylinder. Due to the limitation of the action speed of the cylinder, high-speed production cannot be realized, which affects the production efficiency. During long-term use, the action of the air cylinder may be deflected, and the stroke and speed of the action of the air cylinder may also be 3. When it is necessary to control the wet wipe unwinding roller to stop unwinding, it is necessary to control the unwinding roller to stop slowly by controlling the swing arm to squeeze the friction wet wipe unwinding roller. This method is not only noisy, manual operation is required, the electrical design cannot be realized, and the friction generated during work is likely to cause the deformation of the wet wipe cloth, and it is impossible to realize the immediate stop of the unwinding roller; 4. The structure of the folding assembly of the wet wipe is relatively complicated , and in the forming process of wet wipes, there are often cases where the wet wipes are partially folded or overfolded, and the folding quality is not high
