Corrugated paper pressure damage-free transmission device of paper mounting machine and paper mounting machine

Abstract

The invention relates to the technical field of paper mounting machines, and discloses a pressure-damage-free corrugated paper transmission device of a paper mounting machine and the paper mounting machine. The pressure-damage-free corrugated paper transmission device of the paper mounting machine comprises two front edge mounting plates and two rear edge mounting plates, a conveying wheel set is arranged between the two front edge mounting plates, and a gluing wheel set is arranged between the two rear edge mounting plates; the conveying wheel set comprises a conveying shaft rotationally arranged between the two sets of front edge mounting plates, a plurality of conveying wheels are arranged on the conveying shaft, the tops of the two sets of front edge mounting plates are connected through a top plate, and first through grooves with the number equal to that of the conveying wheels are formed in the top plate; the top end face of the periphery of the conveying wheel extends out of the through groove. The output end of the first driving mechanism is connected with the conveying shaft and the gluing wheel set. The conveying wheel set and the gluing wheel set are both driven by the first driving mechanism to rotate synchronously, the conveying wheels on the conveying wheel set convey the backing paper to the gluing wheel set, and compared with the prior art, one step of pressing is omitted, and stress damage to the backing paper is reduced.

Description

technical field [0001] The invention relates to the technical field of laminating machines, in particular to a pressure-damage-free transmission device for corrugated paper of a laminating machine and a laminating machine. Background technique [0002] The laminating machine is mainly used to mount two or more sheets of paper together. During the working process of the laminating machine, the printed surface paper needs to be mounted on the bottom paper (corrugated paper) of the lower layer by pasting. . The transmission of the bottom paper in the prior art such as patent CN202111072973.2 and figure 1 As shown, the backing paper A is conveyed to the pair of conveying rollers C through the conveyor belt B, and then the pair of conveying rollers C conveys the backing paper A to the gluing pair of rollers D for gluing, and finally the lamination is completed; usually after the lamination is completed Finally, there are two main ways to judge whether the product is qualified, ...

AI Technical Summary

Problems solved by technology

Adopting the scheme of CN202111072973.2 can meet the requirements in terms of alignment and gram weight, but there are two problems. On the one hand, the backing paper will pass through the pressure of the two sets of rollers, the conveying pair C and the gluing pair D. Once it is pressed, the structure of the backing paper will be destroyed, so that the stress of the backing paper will be destroyed. In the actual test test, three sets of heavy impact tests are carried out on the backing paper. The first test is that the backing paper has not been pressed, and the second test is It is the backing paper that has been pressed by the pair of rollers once, and the test three is the backing paper that has been pressed by the pair of rollers twice. The three sets of test data are taken for comparison. The gravity impact that test 1 can withstand is between 1.22 and 1.38 of test 3; on the other hand, it is conveyed through conveyor belt B. To complete the transmission of the bottom sheet of bottom paper A, conveyor belt B must keep rotating. When the conveyor belt conveys the bottom sheet of backing paper A, during the transmission process, the tail of the penultimate backing paper A will fall into the tail of the conveyor belt under the action of gravity for transmission, which will make the laminating machine When the leading edge paper feeding drive device conveys the backing paper, paper jams will occur, which will affect the production efficiency. In addition, when the last backing paper A is completely detached from the conveyor belt, the penultimate backing paper A will press the last one. The tail of the backing paper A also affects the transmission efficiency
