Description

Technical Field

[0001] The present invention relates to the technical field of packaging machinery and equipment, and in particular to a multi-link pressing and smoothing machine and packaging production equipment. Background Art

[0002] With the continuous development of the economy and society, people's living standards are constantly improving, and the quality of product packaging appearance is getting higher and higher. The exquisite outer packaging of many exquisite items such as mobile phones, jewelry, gifts, cigarettes and other high-consumption products has gradually become part of product competitiveness. Therefore, packaging production has also become a very important part of the industry. Packaging equipment also has a very large room for development, gradually transforming from the initial manual packaging to automation and efficiency.

[0003] In packaging boxes such as cigarette and wine boxes, gray board and facial tissue are generally used. Gray board is used as the internal support of the packaging box, and facial tissue is used as the external surface of the packaging box. When processing the packaging box, the gray board is generally made into a box blank first, and then the laminated facial tissue is wrapped on the outer surface of the box blank. Finally, the bubble removal is performed to obtain the final packaging box product. Among them, in some packaging methods, the side wall of the gray board inner shell is first covered with a circle of packaging facial tissue, such as Figure 1a As shown in the figure, the edge of the packaging paper on the side near the bottom of the box protrudes from the bottom of the inner shell. It is necessary to flatten the edge of the paper so that it fits the bottom of the inner shell to form a Figure 1b Then, a certain pressure is applied to make the edge of the face paper firmly fit with the bottom of the inner shell. Figure 1a The status shown is Figure 1b The state shown is mostly achieved manually, or by a plurality of cylinders driving the scraper plates to extend and retract to achieve the flattening of the edge of the surface paper.

[0004] In summary, the existing technology has the problem that manual scraping of the edge of the surface paper is time-consuming, labor-intensive and inefficient. The scraping equipment has multiple power sources and a complex equipment structure, which needs to be solved. Summary of the Invention
