The following problems arise during actual operation:

[0004] 1. During the impregnation process of impregnated paper, if there are air bubbles in the glue, the air bubbles may adhere to the surface of the impregnated paper, affecting the uniformity of the surface after impregnation, thereby reducing the quality of the finished impregnated paper. On the other hand, air bubbles can cause voids in the glue, which will have an adverse effect on the adhesive effect of the glue.

[0005] 2. After a certain period of filtration, impurities will accumulate on the filter screen, which will interfere with the filtration speed. Therefore, the filter screen needs to be replaced frequently to improve the filtration speed of the glue. Utility Model Content

[0026] The adhesive in the open working box 2 is sequentially returned to the open working box 2 through the first connecting pipe 32, the transfer box 31, and the second connecting pipe 33 by the suction pump 34. This allows the adhesive in the open working box 2 to be heated and filtered in the transfer box 31.

[0029] As a possible implementation of this solution, preferably, the scraping mechanism 5 includes a pair of pressure roller assemblies 51 and a pair of return springs 52 symmetrically disposed between the two pressure roller assemblies 51 and respectively located in the opposite side walls of the open working box 2; each pressure roller assembly 51 includes a pressure roller 511 transversely disposed between the opposite side walls of the open working box 2 along the width direction of the open working box 2 and a pair of sliders 512 symmetrically fixed at both ends of the pressure roller 511; the two ends of the return springs 52 are respectively fixed to the sliders 512 on the corresponding sides of the two sets of pressure roller assemblies 51. Between; the open working box 2 has vertically arranged grooves 21 corresponding to the positions of each slider 512 in the side wall, and the slider 512 is slidably disposed in the corresponding groove 21; by the two pressure rollers 51 approaching each other on one side and abutting against the two sides of the impregnated paper respectively, on the one hand, the glue on the surface of the impregnated paper can be evenly coated to avoid excess glue accumulating on the surface of the impregnated paper and affecting the impregnation quality, on the other hand, excess glue can also be scraped back into the open working box 2, so that the excess glue is combined with the glue in the open working box 2 for the subsequent impregnation operation of the impregnated paper.

[0030] As a possible implementation of this solution, preferably, an ultrasonic vibrating plate 6 is fixedly provided at the bottom of the open working box 2; by setting the ultrasonic vibrating plate 6, the air bubbles in the glue can be further shaken out by vibration, so as to avoid the air bubbles in the glue from adhering to the surface of the impregnated paper as much as possible, thereby improving the impregnation quality of the impregnated paper.

[0031] The working principle of this device is as follows:

[0032] In use, one end of the impregnated paper is passed between the two pressure rollers 51 and moved to the outside of the open working box 2. Then, the linear drive 41 is turned on to drive the fixed plate 42 to drive the lower pressure frame 43 to press the impregnated paper downward into the glue in the open working box 2. After the impregnated paper is immersed in the glue for a period of time, the area of ​​the impregnated paper that has been immersed in the glue is moved towards the two pressure rollers 51 to scrape off the excess glue on the impregnated paper. On the one hand, this can prevent excess glue from remaining on the impregnated paper and affecting the glue uniformity of the impregnated paper. On the other hand, it can reduce glue waste. The excess glue will fall into the open working box 2 and mix with the original glue in the open working box 2, so that it can impregnate the subsequent impregnated paper together.
