Technical Field

[0001] This utility model relates to the field of paper sizing machine technology, and in particular to a paper sizing machine roller surface cleaning structure. Background Technology

[0002] Paper sizing machines are an important piece of equipment in paper production. They are mainly used to apply sizing agents to the surface of paper, giving the paper the required physical properties. The sizing process helps to improve the paper's durability, printability, and surface quality. The working principle of the sizing machine is to apply sizing agents to the paper surface through a sizing roller.

[0003] If the sizing agent is uneven on the surface of the sizing roller, it may be due to the dryness of the surface area of ​​the sizing roller, which causes the sizing agent to not be evenly distributed and cannot firmly adhere to the roller surface, increasing the problems of sizing agent drying and uneven adhesion. To address this, it is necessary to design a roller surface cleaning structure for paper sizing machines. By spraying water on the surface of the sizing roller, it is helpful to adjust the wetness of the surface of the sizing roller, reduce the adhesion of the sizing agent, and thus make the sizing agent distribution more uniform. Utility Model Content

[0004] The purpose of this invention is to provide a paper sizing machine roller surface cleaning structure to solve the problems mentioned in the background art, which lead to uneven distribution of sizing agent, failure of sizing agent to adhere firmly to the roller surface, and increased drying and uneven adhesion of sizing agent.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a paper sizing machine roller surface cleaning structure, comprising a sizing machine body, with protruding plates on both sides of the sizing machine body, and two sizing rollers inside the sizing machine body. Embedded rods are inserted into the interior of each of the two protruding plates, with a vertical rod at one end of each of the two embedded rods, and a U-shaped tube at one end of each of the two vertical rods. Multiple fan-shaped nozzles are located at the bottom of the U-shaped tube. A support seat is provided on one side of the sizing machine body, and a storage cylinder is placed on top of the support seat. A guide pipe is provided on top of the storage cylinder.

[0006] As a preferred embodiment of this utility model, one end of the guide tube is inserted and connected to an L-shaped tube, and one end of the L-shaped tube is inserted and connected to one side of the U-shaped tube.

[0007] As a preferred embodiment of this utility model, a circulation pump is provided on one side of the guide pipe.

[0008] As a preferred embodiment of this utility model, one end of each of the two embedded rods is fixedly fitted with an anti-dislodgement ring, and the other end of each of the two embedded rods is threaded with a limiting nut.

[0009] As a preferred embodiment of this invention, the diameters of the two anti-detachment rings are both larger than the diameters of the two insert rods.

[0010] As a preferred embodiment of this utility model, the other end of the guide tube is fixedly inserted and connected to the top of the storage cylinder, and one end of each of the two vertical rods is fixedly connected to one end of each of the two embedded rods.

[0011] As a preferred embodiment of this invention, an inlet tube is provided on one side of the storage cylinder.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention incorporates an embedded rod, vertical rods, a U-shaped tube, fan-shaped nozzles, a guide pipe, and a circulation pump. Upon starting the circulation pump, water stored in the storage cylinder is guided through the guide pipe and L-shaped tube to the interior of the U-shaped tube. Subsequently, it is sprayed onto the surface of the two sizing rollers via multiple fan-shaped nozzles, cleaning and lubricating the rollers and preventing uneven distribution of the sizing agent due to surface dryness. This ensures normal subsequent production and the quality of the raw paper. The two embedded rods are inserted into the interior of the convex plate, ensuring the two vertical rods are vertically positioned on both sides of the sizing machine body, thus guaranteeing the stability of the U-shaped tube.

[0014] This utility model incorporates a convex plate, an inlet tube, an anti-disengagement ring, and a limiting nut. After the insert rod is inserted into the convex plate, the bottom surface of the anti-disengagement ring fits against the surface of the convex plate. The limiting nut is then fitted onto one end of the insert rod, and the two are threaded together. This design effectively limits and fixes the convex plate and the insert rod, further enhancing the stability of the U-shaped tube. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution for a paper sizing machine roller surface cleaning structure: Example 1

[0022] like Figure 1-3 As shown, a paper sizing machine roller surface cleaning structure includes a sizing machine body 1. Both sides of the sizing machine body 1 are provided with protruding plates 2. Two sizing rollers 3 are installed inside the sizing machine body 1. Embedded rods 4 are inserted into the interior of each of the two protruding plates 2. A vertical rod 5 is provided at one end of each of the two embedded rods 4. A U-shaped tube 6 is provided at one end of each of the two vertical rods 5. Multiple fan-shaped nozzles 7 are provided at the bottom of the U-shaped tube 6. A support seat 8 is provided on one side of the sizing machine body 1. A storage cylinder 9 is placed on the top of the support seat 8. A guide pipe 10 is provided on the top of the storage cylinder 9. This cleans and lubricates the surfaces of the two sizing rollers 3, preventing the sizing agent from drying out and causing uneven distribution. This ensures normal subsequent production and the quality of the raw paper. The two embedded rods 4 are inserted into the interior of the protruding plates 2, so that the two vertical rods 5 are vertically positioned on both sides of the sizing machine body 1, thus ensuring the stability of the U-shaped tube 6. Example 2

[0023] Based on Example 1, such as Figure 1 and Figure 4 As shown, one end of each of the two embedded rods 4 is fixedly fitted with an anti-detachment ring 14, and the other end of each of the two embedded rods 4 is threaded with a limiting nut 15. The other end of the guide tube 10 is fixedly inserted and connected to the top of the storage cylinder 9. One end of each of the two vertical rods 5 is fixedly connected to one end of each of the two embedded rods 4. By setting up the convex plate 2, the inlet tube 12, the anti-detachment ring 14 and the limiting nut 15, after the embedded rod 4 is inserted into the convex plate 2, the bottom surface of the anti-detachment ring 14 fits against the surface of the convex plate 2. The limiting nut 15 is fitted onto one end of the embedded rod 4, and the two are threaded together, so that the convex plate 2 and the embedded rod 4 can be limited and fixed.

[0024] Working Principle: The paper sizing machine is an important piece of equipment in papermaking production. It is mainly used to apply sizing agents to the surface of paper, imparting the desired physical properties to the paper. The sizing process helps improve the paper's durability, printability, and surface quality. The working principle of the sizing machine is that the sizing roller 3 applies the sizing agent to the paper surface. If the sizing agent is unevenly applied to the surface of the sizing roller 3, it may be due to dryness in certain areas, resulting in uneven distribution and poor adhesion of the sizing agent. This exacerbates the problems of drying and uneven adhesion of the sizing agent. Therefore, a roller surface cleaning structure for the paper sizing machine needs to be designed. By spraying water onto the surface of the sizing roller 3, the moisture state of the surface of the sizing roller 3 is adjusted, reducing the adhesion force of the sizing agent and thus making the sizing agent distribution more even. The sizing roller 3 is made of rubber and metal materials and is driven by a motor. During the sizing process, the sizing roller 3 rotates and directly contacts the surface of the paper, transferring the sizing agent onto the paper. The sizing agent is supplied by a gas supply system installed on the paper sizing machine itself. The glue delivery mechanism delivers the glue to the surface of the glue roller 3. After starting the circulation pump 11, the water stored in the storage cylinder 9 is guided to the interior of the U-shaped tube 6 through the guide pipe 10 and the L-shaped pipe 13. Subsequently, it is sprayed onto the surface of the glue roller 3 through multiple fan-shaped nozzles 7, cleaning and lubricating the surfaces of the two glue rollers 3. This prevents the glue roller 3 from drying out, which would cause uneven distribution of the glue and ensure normal subsequent production and the quality of the raw paper. This solves the problem of uneven distribution of the glue due to dryness on the surface of the glue roller 3. To address the issue of the adhesive not adhering firmly to the roller surface, two insert rods 4 are inserted into the interior of the convex plate 2, so that the two vertical rods 5 are vertically positioned on both sides of the adhesive applicator body 1, thus ensuring the stability of the U-shaped tube 6. After the insert rods 4 are inserted into the interior of the convex plate 2, the bottom surface of the anti-detachment ring 14 is in contact with the surface of the convex plate 2. The limiting nut 15 is fitted onto one end of the insert rod 4, and the two are threaded together, thereby limiting and fixing the convex plate 2 and the insert rod 4, further enhancing the stability of the U-shaped tube 6.
