Description

Technical Field

[0001] This utility model belongs to the field of glue coating machine technology, specifically relating to a glue coating machine for label and sticker production. Background Technology

[0002] Label and sticker production glue coating machines are automated devices primarily used to evenly apply liquid adhesive to the surface of labels, stickers, and other materials. They control the adhesive flow and coating path through pneumatic, electric, or mechanical drives to ensure precise adhesion to designated locations. Common types include drum glue coating machines, double-acting / double-station glue coating machines, and three-axis linkage glue coating machines. Label and sticker production glue coating machines can replace manual glue application, not only improving production efficiency and reducing labor costs but also ensuring precision in adhesive application, avoiding waste. They are widely used in product label production in the food, pharmaceutical, and cosmetic industries.

[0003] Chinese Patent Publication No. CN219296475U discloses a glue coating machine for electronic tag production, including a glue coating box. A glue sprayer is fixedly connected to the top of the glue coating box, and a conveyor belt is installed at the bottom of the inner wall of the glue coating box. An opening is provided on the left side of the bottom of the glue coating box, and a water tank is fixedly connected to the left side of the bottom of the glue coating box. A water pump is fixedly connected to the right side of the inner wall of the water tank. A support plate is fixedly connected inside the opening, and a water spray pipe is movably connected to the inside of the support plate through a bearing. This utility model uses a water pump to spray water through the water spray pipe to wash the conveyor belt. Then, a motor and worm gear drive a brush plate through the water spray pipe to brush and clean the conveyor belt. Finally, an impeller and a heating pipe exhaust hot air through a square sleeve to blow and dry the conveyor belt. This achieves the advantages of convenient cleaning, eliminating the need for manual cleaning by the user after use, resulting in high cleaning efficiency and saving the user a lot of time.

[0004] In practical use, this utility model typically utilizes a conveyor belt to transport labels. During prolonged operation, residual adhesive, dust, paper scraps, and other industrial impurities gradually accumulate on the surface of the conveyor belt. These contaminants may penetrate into the microscopic pores of the conveyor belt material, forming stubborn stains that are difficult to remove. Existing label coating machines typically employ a single brush cleaning system, which has significant limitations. The contact area between the brush and the conveyor belt is limited, making it difficult to fully cover all areas of a wide conveyor belt. This makes it impossible to effectively remove thick adhesive layers or hard particles, leading to residual adhesive accumulation that alters the surface friction coefficient, affects label positioning accuracy, and may even cause the conveyor belt to slip or the label to shift. Consequently, the practicality of the label coating machine used in label production is somewhat lacking. Utility Model Content

[0005] This utility model proposes a glue applicator for label and sticker production to solve the problem of the difficulty in thoroughly cleaning residual glue or impurities on conveyor belts in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a glue coating machine for label and sticker production, comprising:

[0007] Mounting frame and glue applicator body;

[0008] Multiple guide rollers are all set inside the mounting frame. The bottom end of the mounting frame is provided with a water storage tank. The water storage tank is provided with a U-shaped positioning frame.

[0009] A positioning shaft is rotatably connected to a positioning frame, and a positioning roller is provided on the outside of the positioning shaft. Multiple guide rollers and positioning rollers are provided with the same conveyor belt.

[0010] An adhesive application assembly is installed inside the main body of the adhesive application machine. The upper end of the main body of the adhesive application machine is provided with a storage box, and the bottom end of the storage box is connected to the adhesive application assembly.

[0011] In order to effectively clean the conveyor belt, the positioning frame is further provided with a U-shaped fixing frame on both sides, and a limiting groove is provided through the two fixing frames. The same limiting frame is provided in the two limiting grooves. The inner wall of the limiting frame is provided with a first cleaning brush on both sides, and the two first cleaning brushes are respectively against the two sides of the conveyor belt.

[0012] In a preferred embodiment, both ends of the positioning shaft extend to the outside and are provided with cams, with the upper ends of the two cams respectively abutting against the bottom ends of the limiting frame.

[0013] In a preferred embodiment, the limiting frame is provided with multiple limiting springs on both the upper and lower sides, and the other ends of the multiple limiting springs are respectively provided on the upper and lower sides of the two limiting grooves.

[0014] In a preferred embodiment, the bottom of the water storage tank is provided with an installation sleeve, and multiple compression springs are provided inside the installation sleeve. The other end of the multiple compression springs is provided with the same second cleaning brush, and the upper end of the second cleaning brush abuts against one side of the conveyor belt.

[0015] In a preferred embodiment, an electric push rod is provided inside the mounting frame, and the output end of the electric push rod is located at the upper end of the positioning frame.

[0016] To ensure the quality of the adhesive coating on the label stickers, a support plate is further provided on one side of the mounting frame located at the upper end of the conveyor belt. A dust suction hood is provided at the bottom end of the support plate. An exhaust hood is provided inside the mounting frame located at the bottom end of the conveyor belt.

The air inlet of the pump body is connected to one side of the filter box, and the air outlet of the pump body is connected to one side of the heating box. The two ventilation pipes are respectively connected to the other side of the filter box and the heating box.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model, through the first cleaning brushes set on both sides of the limiting frame and the cams at both ends of the positioning shaft, in conjunction with the second cleaning brush in the water tank, allows the conveyor belt to be completely immersed in the water tank when it is moving, removing dirt attached to the surface of the conveyor belt and initially dissolving residual adhesive. The first and second cleaning brushes can further remove stubborn residual adhesive and other impurities from the surface of the conveyor belt. The cams at both ends of the positioning shaft drive the two first cleaning brushes in the water tank to scrape and clean the conveyor belt through periodic lifting and lowering movements. This not only significantly improves the cleanliness of the conveyor belt and effectively avoids the adverse effects of residual adhesive and impurities on the subsequent label and sticker coating quality, but also greatly enhances the stability and practicality of the coating machine in the production process.

[0020] 2. This utility model, through the dust suction hood installed at the upper end of the conveyor belt and the exhaust hood at the lower end, not only achieves efficient absorption of dust and fine impurities on the surface of the conveyor belt and the labels, effectively reducing the adverse effects of these contaminants on the quality of label inspection, ensuring the cleanliness of the labels and the aesthetics of the final product, but also allows the exhaust hood at the lower end to blow dry the conveyor belt after the washing process, quickly removing residual moisture from the surface of the conveyor belt and restoring it to a suitable dry state. This not only avoids problems such as slippage or paper jams caused by a wet conveyor belt, but also ensures that the conveyor belt can transport labels more smoothly and efficiently, thereby greatly improving the working efficiency of the glue coating machine and the overall operational stability of the production line.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0028] Example 1:

[0029] Please see Figure 1-5 This utility model provides a glue coating machine for label sticker production, comprising:

[0030] Mounting frame 1 and glue applicator body 2;

[0031] Multiple guide rollers 3 are all set inside the mounting frame 1. The bottom of the mounting frame 1 is provided with a water storage tank 4, and the water storage tank 4 is provided with a "U"-shaped positioning frame 5.

[0032] The positioning shaft 6 is rotatably connected to the positioning frame 5. The positioning roller 7 is provided on the outside of the positioning shaft 6. Multiple guide rollers 3 and positioning roller 7 are provided with the same conveyor belt 8.

[0033] The glue application component 9 is installed inside the glue application machine body 2. The glue application machine body 2 has a storage box 10 at the upper end, and the bottom end of the storage box 10 is connected to the glue application component 9.

[0034] Specifically, such as Figure 2 , Figure 3 and Figure 5 As shown, the positioning frame 5 has a U-shaped fixing frame 11 on both sides. The two fixing frames 11 are provided with a limiting groove. The two limiting grooves are provided with the same limiting frame 12. The inner walls of the limiting frame 12 are provided with first cleaning brushes 13 on both sides. The two first cleaning brushes 13 are respectively against the two sides of the conveyor belt 8.

[0035] Through its design, the limiting grooves in the two fixed frames 11 can limit the movement of the limiting frame 12, preventing it from shifting position during movement. The first cleaning brushes 13 on both sides of the conveyor belt 8 can conveniently and effectively clean the residual glue and impurities on its surface when the conveyor belt 8 is moving, so that the glue applicator can better perform glue application on the label stickers.

[0036] Specifically, such as Figure 3 As shown, both ends of the positioning shaft 6 extend to the outside and are provided with cams 14. The upper ends of the two cams 14 respectively abut against the bottom sides of the limit frame 12. When the conveyor belt 8 is running, it will drive the positioning shaft 6 to rotate, which will drive the cams 14 on both sides to rotate. The two cams 14 will push the limit frame 12 to move, which will drive the two first cleaning brushes 13 to move on the surface of the conveyor belt 8, thereby improving its cleaning effect on the conveyor belt 8.

[0037] Specifically, such as Figure 2 , Figure 3 and Figure 5 As shown, multiple limiting springs 15 are provided on both the upper and lower sides of the limiting frame 12. The other ends of the multiple limiting springs 15 are respectively set on the upper and lower sides of the two limiting grooves. The multiple limiting springs 15 can limit the position of the limiting frame 12. In conjunction with the two cams 14, the limiting frame 12 and the two first cleaning brushes 13 can achieve reciprocating motion, thereby cleaning the conveyor belt 8 more effectively.

[0038] Specifically, such as Figure 2 and Figure 5 As shown, the bottom of the water tank 4 is provided with an installation sleeve 16, and multiple compression springs 17 are provided inside the installation sleeve 16. The other end of the multiple compression springs 17 is provided with the same second cleaning brush 18. The upper end of the second cleaning brush 18 abuts against one side of the conveyor belt 8. The multiple compression springs 17 can ensure that the second cleaning brush 18 can always abut against the outside of the conveyor belt 8, thereby further improving the cleaning effect when the conveyor belt 8 is running.

[0039] Specifically, such as Figure 2 As shown, the mounting frame 1 is equipped with an electric push rod 19. The electric push rod 19 is existing technology and will not be described in detail here. The output end of the electric push rod 19 is located at the upper end of the positioning frame 5. The output end of the electric push rod 19 can drive the positioning frame 5 to move up and down. The positioning frame 5 can adjust the position of the positioning shaft 6 and the positioning roller 7, thereby adjusting the tension of the conveyor belt 8 so that it can better transport the label stickers.

[0040] See Figure 1-5When using a glue applicator to apply glue to labels, the labels are first placed on the conveyor belt 8, which then transports them into the glue applicator body 2. The glue applicator assembly 9 then applies the glue. During operation, the conveyor belt 8 enters the water tank 4, where it comes into full contact with the cleaning solution. As the conveyor belt 8 moves, it comes into contact with the two first cleaning brushes 13 and the second cleaning brush 18, effectively cleaning residual glue and impurities from the surface. The movement of the conveyor belt 8 also drives the positioning roller 7 and the positioning shaft 6 to rotate. The positioning shaft 6 then drives the cams 14 at both ends to rotate, which in turn pushes the limit frame 12 to move. The limit frame 12 then moves the two first cleaning brushes 13, thus thoroughly and effectively cleaning residual glue and impurities from the conveyor belt 8, ensuring the quality of the label production.

[0041] Example 2:

[0042] Please see Figure 1-5 This utility model provides a glue coating machine for label sticker production, comprising:

[0043] Mounting frame 1 and glue applicator body 2;

[0044] Multiple guide rollers 3 are all set inside the mounting frame 1. The bottom of the mounting frame 1 is provided with a water storage tank 4, and the water storage tank 4 is provided with a "U"-shaped positioning frame 5.

[0045] The positioning shaft 6 is rotatably connected to the positioning frame 5. The positioning roller 7 is provided on the outside of the positioning shaft 6. Multiple guide rollers 3 and positioning roller 7 are provided with the same conveyor belt 8.

[0046] The glue application component 9 is installed inside the glue application machine body 2. The glue application machine body 2 has a storage box 10 at the upper end, and the bottom end of the storage box 10 is connected to the glue application component 9.

[0047] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, a mounting plate 20 is provided on one side of the mounting frame 1 at the upper end of the conveyor belt 8, and a dust suction hood 21 is provided at the bottom end of the mounting plate 20. An exhaust hood 22 is provided inside the mounting frame 1 at the bottom end of the conveyor belt 8. A pump body 23 is provided on one side of the mounting frame 1. The pump body 23 is existing technology and will not be described in detail here. A ventilation pipe 24 is provided at one end of both the dust suction hood 21 and the exhaust hood 22.

[0048] Through its design, the dust suction hood 21 on the upper side of the conveyor belt 8 can absorb dust or impurities on the conveyor belt 8 and the label stickers, which not only performs preliminary cleaning of the conveyor belt 8 and improves the effect of subsequent cleaning, but also ensures the quality of the adhesive coating on the label stickers. The exhaust hood 22 at the bottom of the conveyor belt 8 can blow and dry the cleaned conveyor belt 8, ensuring the smooth transport of the label stickers.

[0049] Specifically, such as Figure 1 , Figure 2 and Figure 4 As shown, a filter box 25 is provided on one side of the pump body 23, and a filter plate 26 is provided inside the filter box 25. The filter box 25 and the filter plate 26 on one side of the installation frame 1 can filter the dust or impurities absorbed by the dust collection hood 21. A heating box 27 is provided on the other side of the installation frame 1. The air inlet of the pump body 23 is connected to one side of the filter box 25, and the air outlet of the pump body 23 is connected to one side of the heating box 27. Two ventilation pipes 24 are respectively connected to the other side of the filter box 25 and the heating box 27. When the air drawn by the pump body 23 enters the heating box 27, the temperature will rise. Then, the hot air is blown onto the conveyor belt 8 through the exhaust hood 22, which improves the drying effect of the conveyor belt 8.

[0050] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
