Detailed Embodiment

[0016] The following further illustrates the utility model with reference to the drawings.

[0017] In order to make the purpose, technical solutions and advantages of the utility model clearer, the following further details the utility model in conjunction with the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model.

[0018] Refer to Figure 1, An automatic glue - applying mechanism for paper products, including a box body 1. Clear water is injected into the box body 1. Multiple heaters 2 and a glue - applying pipeline 3 are also arranged in the box body 1. The glue - applying pipeline 3 is of an overall U - shaped structure, and its left and right ends are respectively a feed pipe 31 and a discharge pipe 32. Multiple guide rollers 4 are arranged in the glue - applying pipeline 3. A glue - applying roller 5 and a scraper 6 are respectively arranged at the bottom of the glue - applying pipeline 3. A tank body 7 is also arranged in the box body 1. The tank body 7 is located in the sunken part of the glue - applying pipeline 3. A liquid discharge port 8 is opened at the bottom of the tank body 7, and a material - receiving groove 9 is arranged on the liquid discharge port 8. Multiple nozzles 10 are arranged in an array at the bottom of the material - receiving groove 9. The nozzles 10 extend into the glue - applying pipeline 3. The nozzles 10, the glue - applying roller 5 and the scraper 6 are distributed in sequence according to the conveying direction. Both the glue - applying pipeline 3 and the tank body 7 are immersed in clear water. Specifically, the paper product enters from the feed pipe 31 and, under the action of the guide rollers 4, finally discharges from the discharge pipe 32. During this process, the heater 2 heats the clear water and transfers the heat to the glue - applying pipeline 3 and the tank body 7, making the glue in the tank body in a flowing state, so as to facilitate discharging the glue onto the paper product from the liquid discharge port 8, the material - receiving groove 9 and the nozzles 10, applying glue through the glue - applying roller 5, and then scraping evenly and removing the excess glue through the scraper 6; after uniform coating, since the glue - applying pipeline is still in hot water, the glue can be quickly dried, having the characteristics of evenly coating the applied glue and quickly drying it; the nozzles 10 are equidistantly distributed, which is conducive to the uniform coating of the glue; the scraper 6 is preferably made of elastic rubber material to avoid damaging the paper product.

[0019] In this embodiment, the heaters 2 are respectively located at the bottom and the left and right inner walls of the box body 1 to improve the heating efficiency of the clear water.

[0020] In this embodiment, the glue - applying roller 5 is externally connected to a motor for driving, which is conducive to the glue - applying roller 5 conveying and applying glue to the paper product.

[0021] In this embodiment, a stirring motor 11 is arranged at the top of the tank body 7. The stirring motor 11 is drivingly connected to a stirring shaft 12, and stirring blades 13 are arranged on the stirring shaft 12. By setting the stirring motor 11 to drive the stirring blades 13 to rotate, the rotation of the stirring blades 13 enables the paper glue in the tank body to be fused and stirred, avoiding coagulating into glue blocks in the colloid tank after long - term placement and hindering the discharge of materials, and also improving the quality of subsequent glue application.

[0022] In this embodiment, the liquid discharge port of the tank body 7 is of a funnel - shaped structure and is set to be inclined towards the material - receiving groove 9, facilitating the diversion of the glue into the material - receiving groove 9 for discharging the glue.

[0023] In this embodiment, a collection tank 14 is provided at the bottom of the glue application pipeline 3. The collection tank 14 is located below the glue application roller 5 and the scraper 6. The collection tank 14 is connected to the tank body 7 through a recovery pipeline 15 and a recovery pump 16. The collection tank 14 is used to collect the excess glue scraped off by the glue application roller 5 and the scraper 6, and the collected glue is recycled through the recovery pipeline 15 and the recovery pump 16. Since both the collection tank 14 and the recovery pipeline 15 are in hot water, it is beneficial for recycling.

[0024] As mentioned above, it is only used to illustrate the technical solution of the present invention rather than to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention shall be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
