Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, and in particular to a laminating mechanism of a paper laminating machine for producing packaging boxes. Background Art

[0002] Paper-mounting machine is a mechanical device that glues two different papers together. Paper-mounting machine is divided into three types according to the machine type: fully manual operation and simple structure, semi-automatic and fully automatic. The structure, performance and price of different types of paper-mounting machine are also very different. What type of paper-mounting machine to choose for production mainly depends on the structure and characteristics of the factory's products. Reasonable arrangement of suitable machines for production is more beneficial to improving production efficiency and quality. The specifications of paper-mounting machine are relative to the length of the roller. In order to avoid waste of adhesives, energy consumption and increase in production costs, in factories with more diversified product structures, when choosing specifications, paper-mounting machines of different sizes should be appropriately purchased in proportion to meet the requirements of efficient and reasonable production. Some factories mainly produce narrow-width products. In order to make the machines adaptable to large-size products, they all purchase large-size machines for production. They think that large-size machines can be large or small and have strong adaptability. In fact, this practice is not advisable. Although there are many types of paper laminating machines, the existing paper laminating machines have some problems during use, especially the laminating effect is not ideal, which easily makes the bonding between papers unstable. Therefore, it is necessary to design a new type of laminating machine laminating mechanism to solve the existing problems.

[0003] The pressing mechanism of the existing paper laminating machine has certain drawbacks when in use. The pressing speed of the paper laminating machine cannot be controlled according to instructions, and the paper cannot be absorbed, so the pressing effect is not very ideal. Long-term use will cause the paper to deviate. Moreover, the cardboard cannot be cleaned, so the appearance of the finished product is easily contaminated with air impurities, which reduces the quality and brings certain impacts during the operation.

[0004] Therefore, improvements are made to address the above problems. Utility Model Content

[0035] In this embodiment, in order to achieve the effect of heating and pressing the three-layer paperboard, a hot pressing and conveying assembly 5 is designed. Conveying rollers 5-2 are installed on the top and bottom of the layered cavity 2 of the three-layer structure to convey the inner paperboards of the upper and lower layers of the layered cavity 2 respectively.
