Description

Technical Field

[0001] The utility model relates to the technical field of plastic packaging production, in particular to an edge pressing device for producing rectangular plastic packaging bags with a single-side opening. Background Art

[0002] The wave of consumerism has brought consumers a wide variety of goods. In order to stimulate consumers' desire to buy, goods are generally equipped with carefully designed outer packaging. For example, common plastic packaging bags, in addition to beautiful design, plastic packaging bags must also meet basic strength requirements. The more common form is a rectangular plastic packaging bag with a single-side opening. In addition to the final sealing at the opening position, the side opposite and parallel to it is pre-pressed. The bonding and thickness of the press position make this position and the packaging bag as a whole have the required strength. The press process of this type of packaging bag is relatively simple. The main method is to use the traction roller to pull the raw material forward so that the press position stops just below the press structure, and then the press structure moves vertically downward until the press is completed. However, after the traction roller stops rotating, the pulled raw material will still move forward a distance due to inertia, and this distance is not controllable. Therefore, the actual press position often deviates from the expected press position, which in turn affects the overall processing quality. Based on this situation, how to avoid the forward movement of the raw material due to inertia and the resulting offset of the press position as much as possible has become an issue that relevant technical personnel urgently need to solve.

A pipeline 20 is fixedly arranged on the right portion of the power unit 19. Air holes 23 are arranged through the lower portion of the adsorption unit 21.

The output end of the middle cylinder 2 pushes the edge pressing device 3 to move vertically downward until the edge pressing part 25 is tightly fitted with the predetermined edge pressing position of the raw material, and the edge pressing device 3 is kept open, so that the edge pressing part 25 is kept in a state of tight fit with the raw material until the edge pressing is completed, and the power part 19 restores the normal pressure state between the raw material and the vacuum extractor 5 through the air hole 23, and the raw material is separated from the adsorption part 21, so that the left cylinder 1, the middle cylinder 2, and the right cylinder 8 are reset, and the motor 10 is started and its output shaft is reversed until the vacuum extractor 5 moves to the next adsorption position, and then the above-mentioned action can be performed again to perform the next edge pressing work.
