Abstract
Description
Technical Field
[0001] This utility model relates to the field of packaging equipment technology, specifically to a frame-type equipment negative pressure connection structure. Background Technology
[0002] Tissue paper packaging machines are mainly used for bagging and packaging various sizes of soft-pack tissues. They use a tubular film to package the tissues, and a tissue pushing device pushes the tissues into the film for bagging. The bagged tissues are then sealed. Currently, tissue paper packaging machines primarily use negative pressure adsorption for conveying the film and opening the bags. However, after installation, the internal piping of existing packaging machines becomes very messy. This not only easily interferes with the film or other moving parts, affecting subsequent production efficiency, but also makes maintenance and repair inconvenient for staff, resulting in low maintenance efficiency. Utility Model Content
[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a frame-type equipment negative pressure connection structure with simple and orderly pipeline layout, high reliability, and effective improvement of maintenance efficiency and tissue packaging production efficiency.
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] A frame-type equipment negative pressure connection structure includes a frame on which a negative pressure generating fan is mounted. The output end of the negative pressure generating fan is connected to a connecting pipe that is geometrically shaped along the frame. The output end of the connecting pipe is provided with a first negative pressure connection port for connecting to a first negative pressure conveyor belt, a second negative pressure connection port for connecting to a second negative pressure conveyor belt, a third negative pressure connection port for connecting to an upper negative pressure adsorption plate, and a fourth negative pressure connection port for connecting to a lower negative pressure adsorption plate.
[0006] As a further improvement to the above technical solution:
[0007] A first negative pressure on / off switch is provided on the first negative pressure connection port, a second negative pressure on / off switch is provided on the second negative pressure connection port, a third negative pressure on / off switch is provided on the third negative pressure connection port, and a fourth negative pressure on / off switch is provided on the fourth negative pressure connection port.
[0008] The number of groups of the first negative pressure connection port, the first negative pressure on / off switch, the second negative pressure connection port, and the second negative pressure on / off switch is all set to one group;
[0009] The third negative pressure connection port, the third negative pressure on / off switch, the fourth negative pressure connection port, and the fourth negative pressure on / off switch are all provided in two sets.
[0010] The first negative pressure connection port is connected to the first negative pressure conveyor belt via a flexible hose, the second negative pressure connection port is connected to the second negative pressure conveyor belt via a flexible hose, the third negative pressure connection port is connected to the upper negative pressure adsorption plate via a flexible hose, and the fourth negative pressure connection port is connected to the lower negative pressure adsorption plate via a flexible hose.
