Technical Field

[0001] This utility model relates to an adhesive application mechanism, specifically an adhesive application mechanism for food packaging paper production, and belongs to the technical field of adhesive application mechanisms. Background Technology

[0002] Packaging paper is usually made of multiple layers of different materials. Common combinations include paper and plastic film, paper and aluminum foil, etc. The adhesive coating process is extremely important in the production of packaging paper. Through adhesive coating, these different materials can be tightly and firmly bonded together, thereby forming packaging materials with better overall performance.

[0003] However, when applying glue, the glue applicator on the glue applicator usually pours the glue directly between two glue rollers. When the equipment runs at a slow speed, the glue stays between the rollers for a long time. The glue is exposed to the air for a long time, and its surface will gradually solidify. In addition, some components in the glue will precipitate when it is still. This will lead to uneven glue concentration and changes in performance, affecting the glue application effect. Utility Model Content

Detailed Implementation

[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 1-6 As shown, a gluing mechanism for food packaging paper production includes a worktable 1. A gluing roller 6 is rotatably connected to the worktable 1 via a rotating shaft. A gluing structure 2 is provided on the worktable 1. The gluing structure 2 includes a storage frame 201. The storage frame 201 is detachably connected to the worktable 1. Two connecting shafts 202 are rotatably connected inside the storage frame 201. Multiple stirring rods 203 are fixedly connected to the connecting shafts 202. A pulley 205 is installed on the connecting shaft 202. The two pulleys 205 are driven by a belt. A motor 204 is installed on the storage frame 201. One of the connecting shafts 202 is fixedly connected to the output shaft of the motor 204.

[0025] As a technical optimization of this utility model, the storage frame 201 is provided with a sealing structure 3, the sealing structure 3 including a sealing block 301, the sealing block 301 is slidably connected to the storage frame 201, and two connecting blocks 303 are fixedly connected to the storage frame 201. One of the connecting blocks 303 is threadedly connected to a first lead screw 302, the first lead screw 302 is threadedly connected to the sealing block 301, and a guide rod 304 is fixedly connected to the sealing block 301, the guide rod 304 is slidably connected to the other connecting block 303. First, the two adjusting frames 402 are installed on the gluing machine with bolts. When applying glue, the glue is poured into the storage frame 201. Then, the first lead screw 302 is rotated. The rotation of the first lead screw 302 will drive the sealing block 301 to move upward, thus sealing the block. A gap is formed between the sealing block 301 and the storage frame 201. The sealing block 301 not only seals the bottom of the storage frame 201, but also controls the flow of the adhesive. At this time, the adhesive drips from the storage frame 201 between the two gluing rollers 6. The two rotating gluing rollers 6 apply the adhesive to the packaging paper. At the same time, the motor 204 is started. The rotation of the output shaft of the motor 204 drives one of the connecting shafts 202 to rotate. This connecting shaft 202 drives the other connecting shaft 202 to rotate through the pulley 205. When the connecting shaft 202 rotates, it drives the stirring rod 203 to stir the adhesive. Stirring the adhesive by the stirring rod 203 can prevent the adhesive from solidifying on the surface due to long-term contact with air, and can also prevent the adhesive components from settling in a static state, thereby avoiding changes in the concentration and properties of the adhesive from affecting the gluing effect.

[0026] As a technical optimization of this utility model, the storage frame 201 is provided with an adjustment structure 4, the adjustment structure 4 including a fixing block 401, two fixing blocks 401 are fixedly connected to the storage frame 201, and an adjustment frame 402 is slidably connected to the fixing block 401. A second lead screw 403 is rotatably connected to one of the adjustment frames 402, and one fixing block 401 is threadedly connected to the second lead screw 403. One adjustment frame 402 is provided with a scale bar 405, and a guide post 404 is fixedly connected inside the other adjustment frame 402. One of the fixed blocks 401 is slidably connected to the guide post 404. If it is necessary to adjust the height of the glue roller 6 according to the packaging paper, the second lead screw 403 is rotated. The second lead screw 403 drives the fixed block 401 to slide in the adjustment frame 402 through the thread. The fixed block 401 drives the worktable 1 to slide up and down. When the worktable 1 slides up and down, the fixed block 401 on one side will slide and cooperate with the guide post 404. The guide post 404 makes the worktable 1 more stable during the adjustment process. At the same time, the sliding distance can be observed through the scale strip 405, thereby accurately adjusting the height of the glue roller 6 and improving the adjustment efficiency.

[0027] As a technical optimization of this utility model, the storage frame 201 and the workbench 1 are installed via an installation structure 5. The installation structure 5 includes a positioning sleeve 501. Two positioning sleeves 501 are fixedly connected to the workbench 1. Two positioning rods 206 are fixedly connected to the storage frame 201. The positioning rods 206 are inserted into the positioning sleeves 501. Limiting rods 502 are slidably connected to the positioning sleeves 501. The limiting rods 502 are engaged with the positioning rods 206. A pull rod 503 is fixedly connected between the two limiting rods 502. A tension spring 504 is fixedly connected between the pull rod 503 and the positioning sleeve 501. A stop block 507 is fixedly connected to the workbench 1. A threaded post 505 is threadedly connected to the pull rod 503. A rotating rod 506 is fixedly connected to the column 505. When the storage frame 201 needs to be disassembled for cleaning, the pull rod 503 is pulled, which causes the limiting rod 502 to slide. At the same time, the tension spring 504 extends. When the limiting rod 502 is no longer engaged with the positioning rod 206, the rotating rod 506 is rotated to a vertical position and blocked by the stop block 507. At this time, the limiting rod 502 will not reset under the action of the tension spring 504, and the storage frame 201 can be removed from the workbench 1 for cleaning. After cleaning, the positioning rod 206 is inserted into the positioning sleeve 501. The limiting rod 502 engages with the positioning rod 206 under the action of the tension spring 504, and the installation is completed. The engagement of the limiting rod 502 with the positioning rod 206 facilitates the quick installation of the storage frame 201 and improves the installation efficiency.

[0028] In use, the two adjusting frames 402 are first installed on the gluing machine with bolts. During gluing, the glue is poured into the storage frame 201. Then, the first lead screw 302 is rotated. The rotation of the first lead screw 302 causes the sealing block 301 to move upwards, creating a gap between the sealing block 301 and the storage frame 201. The sealing block 301 not only seals the bottom of the storage frame 201 but also controls the flow rate of the glue. At this time, the glue drips from the storage frame 201 between the two gluing rollers 6. The two rotating gluing rollers 6 then apply the glue to the packaging paper. Simultaneously, the motor 204 is started. The rotation of the output shaft of the motor 204 drives one of the connecting shafts 202 to rotate. This connecting shaft 202 drives the other connecting shaft 202 to rotate via the pulley 205. When the connecting shaft 202 rotates, it drives the stirring rod 203 to stir the adhesive. Stirring the adhesive by the stirring rod 203 can prevent the adhesive from solidifying on the surface due to long-term contact with air, and can also prevent the components of the adhesive from settling in a static state. This avoids changes in the concentration and properties of the adhesive from affecting the gluing effect. If it is necessary to adjust the height of the gluing roller 6 according to the packaging paper, the second lead screw is rotated. 403, the second lead screw 403 drives the fixed block 401 to slide in the adjusting frame 402 via the thread. The fixed block 401 drives the worktable 1 to slide up and down. When the worktable 1 slides up and down, the fixed block 401 on one side will slide and cooperate with the guide post 404. The guide post 404 makes the worktable 1 more stable during the adjustment process. At the same time, the sliding distance can be observed through the scale strip 405, so as to accurately adjust the height of the upper glue roller 6 and improve the adjustment efficiency. When it is necessary to disassemble the storage frame 201 for cleaning, pull the pull rod 503. The pull rod 503 drives the limit rod 502 to slide, and at the same time the tension spring 5 04. After the limit rod 502 is no longer engaged with the positioning rod 206, rotate the rotating rod 506 to make it rotate to a vertical position and be blocked by the stop block 507. At this time, the limit rod 502 will not reset under the action of the tension spring 504. The storage frame 201 can be removed from the workbench 1 for cleaning. After cleaning, insert the positioning rod 206 and the positioning sleeve 501. The limit rod 502 engages with the positioning rod 206 under the action of the tension spring 504, and the installation is completed. The engagement of the limit rod 502 and the positioning rod 206 facilitates the quick installation of the storage frame 201 and improves the installation efficiency.
