Description

Technical Field

[0001] The utility model relates to the technical field of paper bag manufacturing, in particular to a paper bag glue spraying and bottom pasting machine. Background Technique

[0002] As one of the branches of paper products, most of the raw materials for the production of paper bags are tree raw materials, which are a renewable green resource. At the same time, they also have the remarkable characteristics of being degradable and recyclable. Therefore, they are widely used in related fields such as the packaging industry. In the stage of the rapid development of the current packaging and transportation industries, the demand for paper bags also shows a continuous upward trend. The production of paper bags includes many processes, and the bottom pasting process is one of them. The bottom pasting process is to sequentially complete processes such as glue application, folding, and flattening at the sealing position of the paper bag, so that one end of the paper bag is sealed and becomes a process flow that can be used. The existing bottom pasting work of paper bags has always been carried out in a traditional bottom pasting method, that is, the cutting and indentation processes of the bag bottom are completed separately first, and then the processes such as glue application, folding, and flattening are sequentially completed manually, that is, the paper bag glue spraying and bottom pasting process flow is completed.

[0003] In the existing bottom pasting process of most paper bags with glue spraying, first, the paper bag is placed on a plane, and then the bottom pasting is carried out. The placement stability of the paper bag is relatively low, and it is mainly fixed by pressing down. Pressing down and fixing at the four corners of the paper bag is likely to affect the glue spraying and bottom pasting at the edge position of the paper bag. It is necessary to design a paper bag glue spraying and bottom pasting machine device to solve the above problems. Summary of the Utility Model

[0010] Further, fixing seats are fixedly connected to the bottoms of the vacuum suction cups, and the fixing seats are respectively fixedly connected to the four corners of the bottom end of the placement plate;

[0014] Further, the size of the circular hole fits the size of the vacuum suction cup, and the vacuum suction cup is tightly engaged with the circular hole;

[0015] Through the above technical solution, after the vacuum suction cup and the circular hole are installed with each other, there is no gap at the connection position. After the paper is adsorbed, it is ensured that the adsorption will not fall off.

[0016] Further, the placement plate is a plastic plate with a thickness of 1 cm;
