Description

Technical Field

[0001] The utility model relates to a sizing structure for improving the bonding performance of high-loose bowl paper, and belongs to the technical field of papermaking. Background Art

[0002] Bucket noodles, as a mid-to-high-end product among instant noodles, continue to increase their market share. At the same time, as papermaking companies pay more and more attention to the indicator of paper bulk, under the same conditions, high-bulk paper will increase paper thickness and stiffness. Since high-bulk paper can replace the original high-quantity paper of the same thickness, it not only saves fiber raw materials, but also reduces production and transportation costs. For papermaking companies, it meets consumers' requirements for paper usage characteristics and brings better economic benefits to the company. Therefore, high-bulk noodle bowl paper is favored by processing plants due to its excellent stiffness and thickness.

[0003] But the problem that follows is that since the thickness of high-bulk noodle bowl paper is thicker than that of ordinary thickness noodle bowl paper, the excessive bulk of the pulp will cause the surface strength of the high-bulk noodle bowl paper to decrease. In order to improve the strength, many companies increase the amount of surface sizing starch to ensure strength when producing high-bulk noodle bowls. However, too much sizing will cause the high-bulk noodle bowl paper to have loose adhesion during bonding, which can easily cause quality problems and lead to claims from customers. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the technical problem to be solved by the utility model is to provide a sizing structure for improving the bonding performance of high-loft noodle bowl paper to solve the above problems.

[0005] The utility model discloses a glue application structure for improving the adhesive performance of high-loose noodle bowl paper, comprising a front glue application roller and a back glue application roller in contact with each other, the front glue application roller and the back glue application roller rotate in opposite directions under the drive of a motor; the front glue application roller is provided with a front glue application metering rod and a front feeding pipe, the front glue application metering rod is in contact with the front glue application roller, and the front glue application metering rod rotates in opposite directions with the front glue application roller under the drive of the motor, and the front feeding pipe is provided with a plurality of nozzles capable of spraying glue liquid onto the front glue application roller; the back glue application roller is provided with a back glue application metering rod and a back feeding pipe, the back glue application metering rod is in contact with the back glue application roller, and the back glue application metering rod rotates in opposite directions with the back glue application roller under the drive of the motor, and the back feeding pipe is provided with a plurality of nozzles capable of spraying glue liquid onto the back glue application roller.

[0006] The sizing process is as follows: starch is sprayed onto the surface of the sizing roller through the nozzle of the feed pipe, and then a certain amount of starch glue is evenly coated on the surface of the sizing roller through the metering rod. After the sizing roller contacts the paper sheet, the starch is transferred to the surface of the paper sheet, making it convenient to control the amount of sizing through metering rods of different types.

[0007] Preferably, the surfaces of the front glue-applying roller and the back glue-applying roller are both coated with a rubber layer.

[0008] According to the rotation direction of the front glue roller, the front feeding pipe is located before the front glue metering rod; according to the rotation direction of the back glue roller, the back feeding pipe is located before the back glue metering rod.

[0009] Preferably, the axes of the front glue roller, the back glue roller, the front glue metering rod, the back glue metering rod, the front feeding pipe and the back feeding pipe are parallel to each other.

[0010] Compared with the prior art, the utility model has the following beneficial effects:
