[0002] In the paper processing industry, sizing is a crucial step, directly impacting the paper's water resistance, stain resistance, strength, and subsequent processing performance. Sizing methods often rely on simple roller coating or spraying techniques. While these technologies meet production needs to a certain extent, they often fall short when faced with the diverse and demanding demands of paper products.

While spray coating offers flexibility for various paper shapes, it presents challenges in controlling glue dosage and ensuring uniformity. Furthermore, most sizing machines are limited to a single gluing method, lacking flexibility and scalability, making it difficult to meet the modern paper processing industry's demand for diversified and efficient production.

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] See also Figures 1 to 4 A high-efficiency sizing machine for transfer and immersion spraying includes two supports 1, a bracket 2 fixedly connected between the upper surfaces of the two supports 1, a receiving box 3 fixedly connected between the opposite side walls of the two supports 1, and a pressure roller 4 rotatably connected to the inner side of the receiving box 3. The upper surface of the bracket 2 is provided with a coating structure for coating glue on the surface of the finished paper.

[0026] like Figure 1 As shown, the coating structure includes a servo motor 5 fixedly connected to the upper surface of the bracket 2, a rotating rod 6 fixedly connected to the output shaft of the servo motor 5, a transmission wheel 7 fixedly connected to the right end of the rotating rod 6, a transmission belt 8 transmission-connected to the outer surface of the transmission wheel 7, a driven wheel 9 transmission-connected to the bottom end of the transmission belt 8, a driving rod 10 fixedly connected to the inner side of the center of the driven wheel 9, a first gear 11 fixedly connected to the left end of the driving rod 10, a second gear 12 engaged with the bottom of the first gear 11, a connecting rod 13 fixedly connected to the inner side of the center of the second gear 12, and a coating cylinder 14 fixedly connected to the outside of the driving rod 10 and the outside of the connecting rod 13 respectively.

[0027] The upper surface of the bracket 2 is provided with a glue spraying component for use with the coating structure.

[0028] It should be noted that the glue spraying assembly includes a glue liquid tank 15 fixedly connected to the upper surface of the bracket 2, a liquid extraction pipe 16 fixedly connected to the left side of the glue liquid tank 15, a glue pump 17 fixedly connected to the left end of the liquid extraction pipe 16, a liquid outlet pipe 18 fixedly connected to the liquid outlet end of the glue pump 17, a connecting pipe 19 fixedly connected to the two liquid outlets of the liquid outlet pipe 18, and a nozzle 20 fixedly connected to the liquid outlet of the connecting pipe 19.

[0029] The two liquid outlets of the liquid outlet pipe 18 are arranged in sequence along the upper and lower directions of the liquid outlet pipe 18 . The upper connecting pipe 19 is located directly above the driving rod 10 , and the lower connecting pipe 19 is located directly below the connecting rod 13 .

[0030] The right end of the connecting tube 19 passes through the left side wall of the bracket 2 and extends to the inner side of the bracket 2 and is fixedly connected to the inner right side wall of the bracket 2. The liquid outlet of the upper connecting tube 19 is set at its bottom, and the liquid outlet of the lower connecting tube 19 is set at its top. The nozzle 20 corresponds to the coating cylinder 14 on the same side up and down.

[0031] The receiving box 3 is located directly below the two coating cylinders 14 . The left end of the pressure roller 4 is rotatably connected to the inner left side wall of the receiving box 3 , and the right end of the pressure roller 4 is rotatably connected to the inner right side wall of the receiving box 3 .

[0032] The left end of the driving rod 10 passes through the right side wall of the bracket 2, the installation opening of the corresponding coating cylinder 14 and the inner left side wall of the bracket 2 in sequence and extends to the inner side of the center of the first gear 11 and is fixedly connected to the first gear 11.

[0033] The right end of the connecting rod 13 passes through the left side wall of the bracket 2 and the installation opening of the corresponding coating cylinder 14 in sequence and is rotatably connected to the inner right side wall of the bracket 2.

[0034] In addition, the coating cylinder 14 is usually made of a material that is wear-resistant, corrosion-resistant and has good adhesion to the glue, such as rubber or special alloy. Its surface can be specially treated, such as frosted or microporous treatment, to increase the adhesion of the glue and coating uniformity.

[0035] The working principle of the above embodiment is:

[0036] The glue pump 17 is driven by electricity to extract the glue from the glue tank 15 and transport it to the connecting pipe 19 through the liquid outlet pipe 18. The double liquid outlet design of the liquid outlet pipe 18 corresponds to the upper and lower connecting pipes 19 respectively, realizing the diversion of the glue. The connecting pipe 19 transports the glue to the nozzle 20, which then coats the surface of the coating cylinder 14 with glue. In addition, the dripping glue can be recovered by the receiving box 3.

[0037] The servo motor 5 drives the rotating rod 6 to rotate, which in turn drives the transmission wheel 7 to rotate. The transmission wheel 7 and the transmission belt 8 work closely together to transmit the rotational motion to the driven wheel 9, forming a continuous and stable transmission chain. The rotation of the driven wheel 9 is transmitted to the first gear 11 through the driving rod 10. The precise engagement of the first gear 11 and the second gear 12 ensures that the power is smoothly transmitted to the connecting rod 13. At this time, the coating cylinder 14 on the outside of the driving rod 10 and the coating cylinder 14 on the outside of the connecting rod 13 rotate synchronously and in opposite directions. Then, the conveyed paper passes between the two coating cylinders 14, and the coating cylinder 14 then coats the glue poured on its surface on the upper and bottom surfaces of the paper.

[0038] In addition, when the conveyed paper reaches the contact area of ​​the pressure roller 4, the surface of the paper is in close contact with the surface of the pressure roller 4. As the paper continues to move, the pressure roller 4 rotates due to the friction of the paper. Subsequently, glue is poured into the receiving box 3 to soak the part of the paper located in the receiving box 3. At the same time, the glue in the receiving box 3 is transferred more evenly to the surface of the paper during the rotation of the pressure roller 4.

[0039] The electrical components mentioned in this article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device that controls a computer, etc., and the existing public power connection technology is not described in detail in this article.

[0040] It should be noted that the terms "comprises," "includes," or any other variations thereof are intended to encompass non-exclusive inclusion, such that a process, method, article, or apparatus that includes a series of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus. In the absence of further limitations, an element defined by the phrase "comprises a ..." does not preclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.
