Description

Technical Field

[0001] The utility model relates to the technical field of papermaking processing, and more specifically, to a surface sizing agent processing device for papermaking. Background Art

[0002] Surface sizing is a process in the processing of paper or paperboard. It is usually located at the end of the drying section of the paper machine. A layer of glue is sprayed on the paper sheet when it is not completely dry but has a certain strength. After subsequent drying, a layer of glue film is formed on the surface of the paper and paperboard, thereby achieving the purpose of changing the surface properties of the paper or paperboard.

[0003] Since existing paper has different sizes, it is difficult to fix it when applying glue, which can easily cause the paper to move and affect the gluing effect. Gluing is mainly applied by dipping the glue roller in the glue or spraying it. The spraying range is fixed and difficult to adjust according to paper of different sizes. The glue roller gluing method can easily cause the glue to overflow from both ends of the glue roller. Both methods can easily cause glue waste and increase the gluing cost. Utility Model Content

[0026] Working principle: When in use, place the paper on the top of the processing table 1, slide the slide frame 2, the slide frame 2 drives the slide bar 201 to slide in the slide groove on the top of the processing table 1, so that the paper is located inside the slide frame 2, and push the push plate 12 toward the end close to each other. The push plate 12 slides in the through hole on the top of the pressure plate 8, driving the positioning block 11 to slide from the positioning groove on the inside of the slide frame 2 into the grooves at both ends of the pressure plate 8. At this time, the limit spring 10 is in a compressed state, the pressure plate 8 and the slide frame 2 are released from the limit, and the pressure plate 8 is slid so that the bottom of the pressure block 9 is aligned with the bottom of the pressure block 9. The two sides of the top of the paper fit together, and then the push plate 12 is released.

Then, the upper end of the pressing plate 13 is squeezed toward the two ends close to the pressing plate 8. The pressing plate 13 drives the clamping plate 14 to rotate, and the clamping plate 14 is out of contact with the pressing plate 8. At this time, the pressing plate 8 and the pressing block 9 are released from the limit, and the sliding pressing block 9 makes the pressing block 9 fit with the four corners of the top of the paper. Then, the pressing plate 13 is released, and the thrust of the torsion spring drives the pressing plate 13 to reverse, and the clamping plate 14 It is clamped and fixed with the pressure plate 8. When applying glue, hold the handle at the top of the connecting ring 7 and press it downward. The connecting ring 7 drives the sliding rod 6 and the top rod 5 to slide downward.

The glue in the material box 18 drips from the discharge pipe 1801 to the glue roller 19. Then move the handle at the top of the connecting ring 7, the connecting ring 7 slides in the limiting hole of the sliding rod 6, and the glue roller 19 rolls on the paper to realize the gluing process of the paper. When the glue roller 19 rolls, the excess glue on the surface is collected by the scraper plate 20. After a certain amount is collected, it overflows through the discharge hole of the scraper plate 20 and drips into the collecting frame 23. The hydraulic pump 26 is started, and the glue in the collecting frame 23 enters the material box 18 through the telescopic tube 24 and the connecting tube 25. When the thickness of the glue on the paper needs to be adjusted, the rotating rod 21 is rotated, and the rotating rod 21 drives the scraper plate 20 to approach the glue roller 19 to reduce the glue attached to the glue roller 19, thereby realizing the adjustment of the glue thickness.
