Description

Technical Field

[0001] This utility model relates to the field of decorative paper impregnation technology, specifically a self-drying paper gluing device. Background Technology

[0002] Sizing paper surfaces can improve the physical strength, abrasion resistance, durability, hand feel, and surface smoothness of paper. It can also overcome defects such as paper fuzzing and dusting. Sizing agents used for surface sizing mainly include animal glue, starch, polyvinyl alcohol, methyl cellulose and carboxymethyl cellulose, paraffin glue, etc. Commonly used surface sizing methods include trough sizing, roller sizing, calendering sizing, and drying cylinder sizing.

[0003] In the prior art, Chinese utility model application number CN202323272646.9 discloses a paper surface sizing device for paper processing, including a support frame. The support frame has a traction component for pulling paper inside. A fixing plate is fixedly installed on the outer surface of the support frame, and a sizing component for applying glue is installed on the fixing plate. The sizing component is fixedly connected to the top of the support frame. A hollow inverted U-shaped block is fixedly installed at the top of the support frame, and a drying component for drying glue is installed on the hollow inverted U-shaped block. A movable hole is opened inside the support frame, and the interior of the movable hole is movably connected to the traction component. The traction component includes a first drive motor, which is fixedly connected to the outer surface of the support frame. The output shaft of the first drive motor is movably connected to the inner cavity of the movable hole. This utility model not only eliminates the need for manual glue application and has a high degree of automation, but also allows for convenient and rapid glue drying.

[0004] Although the glue-applying device in the above technical solution does not require manual assistance in applying glue, the glue is sprayed during the paper glue-applying process. During the air-cooling and drying process, the strong wind can cause the glue layer on the paper surface to ripple, resulting in uneven glue layer thickness after drying. This affects the quality of the glued paper and needs further improvement. Therefore, we need to propose a self-drying paper glue-applying device. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0024] Please see Figure 1-5This utility model provides a technical solution: a self-drying paper gluing device, comprising:

[0025] The system includes a gluing frame 1 and a glue-dipping tank 9 installed at the bottom of the gluing frame 1. The glue-dipping tank 9 is equipped with a gluing mechanism 4 for gluing paper and a scraping mechanism 12 for smoothing the glue on the paper. The gluing frame 1 is equipped with a drying guide box 11 for drying the paper after gluing. The drying guide box 11 is equipped with a fan module 14. The gluing frame 1 is equipped with a top plate 2 at the top. The top plate 2 can reduce dust falling on the paper surface in the workshop, thereby ensuring the quality of paper production. At the same time, the scraping mechanism can smooth the glue layer after gluing the paper, ensuring uniform glue thickness. The fan module 14 and the drying guide box 11 can repeatedly heat the glued paper, thereby improving the drying efficiency of the paper after gluing.

[0026] The glue scraping mechanism 12 includes a bottom beam 121 fixedly connected to the glue dipping tank 9. Multiple sets of T-shaped rods 122 are slidably inserted into the bottom beam 121. The upper ends of the multiple sets of T-shaped rods 122 all pass through the bottom beam 121 and are fixedly connected to a scraper 124. Springs 123 are sleeved on the outer sides of the multiple sets of T-shaped rods 122. The springs 123 are located between the bottom beam 121 and the scraper 124. The upper end of the scraper 124 is cylindrical. Baffles 125 are provided on both sides of the scraper 124. By utilizing the cylindrical structure on the scraper 124, the glue can be scraped off while avoiding damage to the paper, thereby improving the uniformity of glue application on the paper. At the same time, the scraped glue falls back into the glue dipping tank 9 through the baffles 125, reducing glue waste. Under the action of the springs 123, the scraper 124 can be stably attached to the glued surface of the paper, thereby ensuring the uniformity of glue application.

[0027] The gluing mechanism 4 includes a gluing roller 41 rotatably disposed inside the glue-dipping tank 9. One end of the gluing roller 41 is provided with a connecting shaft that passes through the glue-dipping tank 9 and the gluing frame 1, and one end of the connecting shaft is driven by a motor 42. The motor 42 is disposed on one side of the gluing mechanism 4. While the gluing roller 41 is rotated by the motor 42, glue can be applied to the paper surface through the surface of the gluing roller 41, thereby improving the efficiency of gluing the paper and avoiding glue leakage.

[0028] Multiple sets of first heating rods 10 are arranged at the bottom of the inner cavity of the glue-impregnation tank 9. The multiple sets of first heating rods 10 are arranged at equal intervals and are all arranged on the same plane. The multiple sets of first heating rods 10 prevent the glue in the glue-impregnation tank 9 from solidifying, thereby ensuring that the glue-applying mechanism 4 can stably wet the paper surface with glue and improve the glue-applying efficiency.

[0029] The inner cavity of the gluing frame 1 is rotatably equipped with two sets of feed rollers 3, limit rollers 5, first guide rollers 6, second guide rollers 7, and two sets of output rollers 8. The two sets of feed rollers 3 and the two sets of output rollers 8 are symmetrically arranged. The limit rollers 5 are located directly above the gluing rollers 41. The first guide rollers 6 and the limit rollers 5 are located on the same horizontal plane. The second guide rollers 7 are located directly above the first guide rollers 6. The feed rollers 3 facilitate the feeding of paper from the paper roll, and under the guidance of the limit rollers 5, the first guide rollers 6, the second guide rollers 7, and the output rollers 8, the glued paper is output to the cutting device, thereby improving the efficiency of paper gluing production.

[0030] An air inlet channel 111 is provided on one side of the drying guide box 11. Multiple sets of support beams 13 are installed in the air inlet channel 111. The fan module 14 is fixedly connected to one side of the multiple sets of support beams 13 by bolts. A dustproof net 15 is installed at the air inlet end of the fan module 14. The dustproof net 15 can prevent the fan module 14 from drawing air and introducing external dust into the air inlet channel 111, thereby preventing dust from adhering to the glue layer of the paper and improving the quality of the paper after gluing.

[0031] The inner cavity of the drying guide box 11 is provided with a first guide channel 112 and a second guide channel 113 that are connected to the air inlet channel 111. A flow divider 114 is provided between the first guide channel 112 and the second guide channel 113. Multiple sets of first air outlets 116 are opened on the other side of the drying guide box 11. A preheating chamber 115 is provided between the multiple sets of first air outlets 116 and the second guide channel 113. Multiple sets of preheating rods 119 are provided in the preheating chamber 115. Fan module 14 Air is introduced into the air inlet channel 111, and the air is divided into two by the diverter plate 114, so that the airflow flows to the first guide channel 112 and the second guide channel 113 respectively, forming two sets of drying airflow. The air in the second guide channel 113 enters the heating chamber and is heated by the preheating rod 119 before being blown out through the first air outlet 116, which facilitates the pre-processing and drying of the paper and avoids the glue layer from being scratched after passing the position of the second guide roller 7, thus ensuring the integrity of the glue layer.

[0032] The upper surface of the drying guide box 11 has multiple sets of second air outlets 118. A reheating chamber 117 is provided between the multiple sets of second air outlets 118 and the first guide channel 112. Multiple sets of reheating rods 1110 are provided in the reheating chamber 117. The reheating rods 1110 are used to heat the airflow blown out of the first guide channel. The heated airflow is blown onto the pre-dried paper through the second air outlets 118, thereby improving the drying efficiency of the glue on the paper and improving the firmness of the glue adhering to the paper.

[0033] In use, the paper to be glued passes sequentially through two sets of feed rollers 3, limit rollers 5, glue roller 41, first guide roller 6, second guide roller 7, and two sets of output rollers 8. The motor 42 is started to drive the glue roller 41 to rotate, causing the glue roller 41 to adhere the glue in the glue tank 9 to one side of the paper. During paper transport, the scraper 124 smooths the glue layer on the paper, ensuring a uniform thickness. Simultaneously, during paper transport, the fan module 14 blows air into the first guide channel 112 and the second guide channel 113, expelling... The airflow, after being heated by the preheating rod 119 in the preheating chamber 115, is blown out through the first air outlet 116, thereby preheating and drying the glue on the paper. During the continuous conveying of the paper, the air in the first guide channel 112 enters the reheating chamber 117, is heated by the reheating rod 1110, and is blown out through the second air outlet 118, thereby reheating and drying the paper, improving the drying effect of the paper, improving the firmness of the glue adhering to the paper, thereby improving the quality of paper gluing and improving the efficiency of paper gluing.
