Description

Technical Field

[0001] This utility model relates to the field of self-adhesive preparation technology, and more specifically, it relates to a coating equipment for self-adhesive paper production. Background Technology

[0002] Self-adhesive paper, as one of the common types of specialty paper, is often used for printing trademarks, stickers, etc. During the production of self-adhesive paper, in order to make it easier for the self-adhesive paper to be fixed on the surface of the object, glue coating equipment is usually used to apply glue to the self-adhesive paper.

[0003] Publication No. CN217450813U discloses a dust removal device for adhesive coating production of self-adhesive paper. The technical solution includes a box body. A first vertical plate and a second vertical plate are fixedly installed at the bottom of the inner cavity of the box body. The first vertical plate is located on the front of the second vertical plate. A motor is fixedly installed on the front of the first vertical plate. The output shaft of the motor passes through the first vertical plate and extends into its inner cavity.

[0004] The above technical solution, through the installation of a fan, an air inlet hood, and an air delivery pipe, can absorb impurities on the surface of self-adhesive paper, thereby achieving the effect of dust removal from self-adhesive paper.

[0005] However, when the above-mentioned technical solution removes dust from self-adhesive paper, it only cleans the impurities on one side of the self-adhesive paper through the air intake hood, making it difficult to clean both sides of the self-adhesive paper at the same time, which affects the cleaning effect of impurities on the self-adhesive paper.

[0006] Therefore, a new solution is needed to address this problem. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a coating equipment for the production of self-adhesive paper, which solves the problem that it is difficult to clean both sides of the self-adhesive paper at the same time when removing dust from the self-adhesive paper, thus affecting the cleaning effect of impurities on the self-adhesive paper.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a coating device for producing self-adhesive paper, comprising a device body with an inlet and an outlet and several rollers located inside the device body, two horizontally arranged rotating rollers rotatably connected inside the device body, a cleaning box fixedly connected inside the device body and located between the two rotating rollers, a through groove for the self-adhesive paper to pass through on the side wall of the cleaning box, a scraper first fixedly connected inside the cleaning box, the top of the scraper first and the side wall of the through groove being horizontally arranged with the top of the rotating rollers, a scraper second slidably connected inside the cleaning box, and a driving component for driving impurities on the top of the self-adhesive paper into the bottom of the cleaning box and a collecting component for collecting impurities at the bottom of the cleaning box.

[0009] By adopting the above technical solution, when applying adhesive to self-adhesive paper using a coating equipment, the self-adhesive paper enters the equipment body through the feed inlet, and is then pulled, causing it to contact one of the rotating rollers. The paper continues to be pulled, passing through the cleaning box via a trough, while simultaneously driving the scraper two upwards. Once the paper has completely passed through the cleaning box, the scraper two moves downwards and contacts the top of the paper, then contacts another rotating roller and several other rollers. Finally, the paper is pulled out from the discharge outlet, thus completing the installation of the self-adhesive paper on the coating equipment. When it is necessary to clean both sides of the paper simultaneously, the equipment body drives several rollers to rotate, simultaneously causing the paper to move within the equipment body. At this time, because the top of the scraper one and the top of the rotating roller are in contact... With the adhesive paper horizontally positioned, scraper one is always in contact with the bottom of the adhesive paper as it passes through the cleaning box. Scraper one effectively scrapes away impurities from the bottom of the adhesive paper, which then fall to the bottom of the cleaning box. Simultaneously, scraper two, which is in contact with the top of the adhesive paper when it is installed with the equipment body, cleans away impurities from the top of the adhesive paper as it moves, causing these impurities to accumulate between scraper two and the adhesive paper. The drive assembly then guides these impurities to the bottom of the cleaning box, where a collection assembly collects them. This simultaneous cleaning of both sides of the adhesive paper improves the overall cleaning effect.

[0010] The present invention is further configured such that: the driving component includes an air outlet pipe fixedly connected to the inner wall of the cleaning box; a fan is fixedly connected to the outer wall of the device body; one end of the air outlet pipe faces the adhesive paper and the other end passes through the device body and is fixedly connected to the output end of the fan; an air outlet hole is opened at the bottom of the cleaning box; and a filter screen is fixedly connected to the air outlet hole.

[0011] By adopting the above technical solution, when guiding the impurities on the self-adhesive paper to the bottom of the cleaning box, the fan is turned on, and the fan draws outside air into the air outlet pipe. The air is then blown towards the top of the self-adhesive paper through the air outlet pipe. At this time, the impurities on the top of the self-adhesive paper will be affected by the air and blown up, and will move with the air towards the air outlet at the bottom of the cleaning box. The filter screen on the air outlet can screen the impurities and air, and the screened impurities will fall to the bottom of the cleaning box, thereby achieving the effect of guiding the impurities on the top of the self-adhesive paper to the bottom of the cleaning box.

[0012] The present invention is further configured such that: the collection component includes a collection frame fixedly connected to the outer wall of the device body, the side wall of the collection frame and the bottom of the cleaning box are connected to each other through a collection pipe, and a collection bag is detachably connected to the side of the collection frame near the collection pipe.

[0013] By adopting the above technical solution, when collecting impurities at the bottom of the cleaning box, the impurities at the bottom of the cleaning box can enter the collection pipe through the setting of the collection pipe, and then be transported to the collection bag located at the collection frame through the collection pipe. The collection bag is used to collect the impurities, thereby achieving the effect of collecting dust at the bottom of the cleaning box.

[0014] The present invention is further configured such that: the collecting tube extends through the collecting frame, the collecting tube is provided with an elastic ring, the collecting tube is provided with an annular groove for placing the elastic ring, and the collecting bag is sleeved on the collecting tube and located between the collecting tube and the elastic ring.

[0015] By adopting the above technical solution, when it is necessary to clean the impurities in the collection bag, the elastic ring is driven to deform, causing the elastic ring and the annular groove to separate from each other and from the collection bag. Then the collection bag is removed from the collection tube, and the impurities in the collection bag are cleaned at the same time. After cleaning, the collection bag is put back on the collection tube, and then the elastic ring is driven back into the annular groove, so that the collection bag is located between the elastic ring and the collection tube, thereby achieving the effect of cleaning the impurities in the collection bag.

[0016] The present invention is further configured such that the bottom of the cleaning box is inclined toward the collection pipe.

[0017] By adopting the above technical solution, it is easy to drive the impurities located at the bottom of the cleaning box into the collection tube.

[0018] The present invention is further configured such that: a fixed plate is fixedly connected inside the cleaning box; a slider is fixedly connected to the two side walls of the scraper; a groove is provided on the side wall of the fixed plate for the slider to slide; a gear is rotatably connected to the side of the slider away from the scraper; a rack that meshes with the gear is fixedly connected to the side wall of the groove; a motor is slidably connected to the side wall of the fixed plate; and the output end of the motor is fixedly connected to the gear.

[0019] By adopting the above technical solution, when the scraper blade 2 is moved, the motor is started, which drives the gear to rotate. At the same time, the gear is affected by the rack and drives the gear to move along the rack. Meanwhile, the gear drives the motor and the slider to move along the slide groove, and the scraper blade 2 is moved by sliding, thereby achieving the effect of moving the scraper blade 2.

[0020] The present invention is further configured such that: a slide rail for moving up and down is fixedly connected to the side of the fixed plate away from the scraper plate 2, which is powered by a motor.

[0021] By adopting the above technical solution, it is possible to prevent the motor itself from rotating while the motor is moving, thereby avoiding affecting the normal movement of scraper two.

[0022] In summary, this utility model has the following beneficial effects: When it is necessary to clean both sides of the self-adhesive paper at the same time, the scraper can scrape off the bottom of the self-adhesive paper by means of scraper one, and the scraped impurities will fall to the bottom of the cleaning box. While scraper one cleans the bottom of the self-adhesive paper, scraper two can clean the impurities on the top of the self-adhesive paper and make the impurities on the top of the self-adhesive paper accumulate between scraper two and the self-adhesive paper. At this time, the drive component can guide the impurities on the top of the self-adhesive paper to the bottom of the cleaning box, and the collection component can collect the impurities at the bottom of the cleaning box, thereby achieving the effect of cleaning both sides of the self-adhesive paper at the same time and improving the cleaning effect of impurities on the self-adhesive paper.

[0031] A type of adhesive coating equipment for producing self-adhesive paper, such as Figures 1-4 As shown, the device includes a main body 3 with an inlet 1 and an outlet 2, and several rollers 4 located inside the main body 3. Two horizontally arranged rotating rollers 5 are rotatably connected inside the main body 3. A cleaning box 6 is fixedly connected inside the main body 3 and between the two rotating rollers 5. A through groove 7 is provided on the side wall of the cleaning box 6 for the adhesive paper to pass through. A scraper 8 is fixedly connected inside the cleaning box 6. The top of the scraper 8 and the side wall of the through groove 7 are both horizontally arranged with the top of the rotating rollers 5. A scraper 9 is slidably connected inside the cleaning box 6. The cleaning box 6 is equipped with a drive assembly for driving impurities on the top of the adhesive paper into the bottom of the cleaning box 6, and a cleaning mechanism for the bottom of the cleaning box 6. The collection component collects impurities from the coating equipment. When applying adhesive to self-adhesive paper using the coating equipment, the self-adhesive paper enters the equipment body 3 through the feed port 1. The self-adhesive paper is then pulled, causing it to contact one of the rotating rollers 5. The self-adhesive paper continues to be pulled, driving it through the through groove 7 and through the cleaning box 6. At the same time, the scraper 9 moves upward. After the self-adhesive paper has completely passed through the cleaning box 6, the scraper 9 moves downward and contacts the top of the self-adhesive paper. The self-adhesive paper then contacts another rotating roller 5 and several rollers. Finally, the self-adhesive paper is pulled out from the discharge port 2, thus completing the effect of installing the self-adhesive paper on the coating equipment.

[0032] When it is necessary to clean both sides of the self-adhesive paper simultaneously, the equipment body 3 drives several rollers to rotate, and at the same time, the rollers move the self-adhesive paper within the equipment body 3. Since the top of the scraper 8 and the top of the rotating roller 5 are horizontally positioned relative to each other, the scraper 8 remains in contact with the bottom of the self-adhesive paper as it passes through the cleaning box 6. This scraper 8 effectively scrapes away impurities from the bottom of the self-adhesive paper, which then fall to the bottom of the cleaning box 6. While the scraper 8 is cleaning the bottom of the self-adhesive paper, the self-adhesive paper... When installed with the main body 3, the scraper 2 9 and the top of the self-adhesive paper come into contact with each other. Therefore, as the self-adhesive paper moves, the scraper 2 9 can clean the impurities on the top of the self-adhesive paper and cause the impurities on the top of the self-adhesive paper to accumulate between the scraper 2 9 and the self-adhesive paper. At this time, through the setting of the drive component, the impurities located on the top of the self-adhesive paper can be guided to the bottom of the cleaning box 6, and the collection component can collect the impurities at the bottom of the cleaning box 6. This achieves the effect of cleaning both sides of the self-adhesive paper at the same time, improving the cleaning effect of impurities on the self-adhesive paper.

[0033] like Figures 1-3 As shown, the drive assembly includes an air outlet pipe 10 fixedly connected to the inner wall of the cleaning box 6, and a fan 11 fixedly connected to the outer wall of the device body 3. One end of the air outlet pipe 10 faces the self-adhesive paper, and the other end passes through the device body 3 and is fixedly connected to the output end of the fan 11. An air outlet hole 12 is opened at the bottom of the cleaning box 6, and a filter screen 13 is fixedly connected to the air outlet hole 12. When guiding the impurities on the self-adhesive paper to the bottom of the cleaning box 6, the fan 11 is started, and the fan 11 draws outside air into the air outlet pipe 10. The air outlet pipe 10 blows the air towards the top of the self-adhesive paper. At this time, the impurities on the top of the self-adhesive paper will be affected and blown up by the air, and move with the air towards the air outlet hole 12 at the bottom of the cleaning box 6. The filter screen 13 on the air outlet hole 12 can screen the impurities and air. The screened impurities will fall to the bottom of the cleaning box 6, thereby achieving the effect of guiding the impurities on the top of the self-adhesive paper to the bottom of the cleaning box 6.

[0034] like Figures 1-3As shown, the collection assembly includes a collection frame 14 fixedly connected to the outer wall of the device body 3. The side wall of the collection frame 14 and the bottom of the cleaning box 6 are interconnected by a collection pipe 15. A collection bag 16 is detachably connected to the side of the collection frame 14 near the collection pipe 15. When collecting impurities at the bottom of the cleaning box 6, the collection pipe 15 allows the impurities to enter the collection pipe 15 and be transported to the collection bag 16 located at the collection frame 14. The collection bag 16 collects the impurities, thereby achieving the effect of collecting dust at the bottom of the cleaning box 6. The collection pipe 15 extends into the collection frame 14 and is equipped with an elastic ring 17. An annular groove 18 is provided on the collection pipe 15 for the elastic ring 17 to be placed. The bag 16 is fitted onto the collection tube 15 and located between the collection tube 15 and the elastic ring 17. When it is necessary to clean the impurities in the collection bag 16, the elastic ring 17 is driven to deform, causing the elastic ring 17 and the annular groove 18 to separate from each other and from the collection bag 16. Then the collection bag 16 is removed from the collection tube 15, and the impurities in the collection bag 16 are cleaned. After cleaning, the collection bag 16 is put back onto the collection tube 15, and then the elastic ring 17 is driven back into the annular groove 18, so that the collection bag 16 is located between the elastic ring 17 and the collection tube 15. This achieves the effect of cleaning the impurities in the collection bag 16. The bottom of the cleaning box 6 is tilted towards the collection tube 15, which facilitates the impurities located at the bottom of the cleaning box 6 to enter the collection tube 15.

[0035] like Figure 3 , Figure 4 As shown, a fixed plate 19 is fixedly connected inside the cleaning box 6, and a slider 20 is fixedly connected to the side wall of the scraper 2 9. The side wall of the fixed plate 19 has a groove 21 for the slider 20 to slide. A gear 22 is rotatably connected to the side of the slider 20 away from the scraper 2 9. A rack 23 that meshes with the gear 22 is fixedly connected to the side wall of the groove 21. A motor 24 is slidably connected to the side wall of the fixed plate 19. The output end of the motor 24 is fixedly connected to the gear 22. When the scraper 2 9 is driven to move, the motor 24 is started, driving the gear 22. When rotation occurs, gear 22 is affected by rack 23, causing gear 22 to move along rack 23. At the same time, gear 22 drives motor 24 and slider 20 to move along slide groove 21, and drives scraper 29 to move through sliding, thereby achieving the effect of scraper 29 moving. A slide rail 25 for motor 24 to move up and down is fixedly connected to the side of fixed plate 19 away from scraper 29. This can prevent motor 24 from rotating itself while motor 24 is moving, thereby avoiding affecting the normal movement of scraper 29.

[0036] The working principle of this utility model is as follows: When applying adhesive to self-adhesive paper using the gluing equipment, the self-adhesive paper enters the equipment body 3 through the feed port 1, and then the self-adhesive paper is pulled to make contact with one of the rotating rollers 5. Then the self-adhesive paper is pulled to pass through the cleaning box 6 through the through groove 7, and at the same time the scraper 9 is moved upward. When the self-adhesive paper has completely passed through the cleaning box 6, the scraper 9 is moved downward and makes contact with the top of the self-adhesive paper. Then the self-adhesive paper is made to contact with another rotating roller 5 and several rollers. Finally, the self-adhesive paper is pulled out from the discharge port 2, thus completing the effect of installing the self-adhesive paper on the gluing equipment.

[0037] When both sides of the self-adhesive paper need to be cleaned simultaneously, the main body 3 drives several rollers to rotate, and these rollers simultaneously move the self-adhesive paper within the main body 3. Since the top of scraper 8 and the top of the rotating roller 5 are horizontally positioned relative to each other, scraper 8 remains in contact with the bottom of the self-adhesive paper as it passes through the cleaning box 6. This scraper 8 effectively scrapes away impurities from the bottom of the self-adhesive paper, which then fall to the bottom of the cleaning box 6. Simultaneously, while scraper 8 cleans the bottom of the self-adhesive paper, scraper 9, which is in contact with the top of the self-adhesive paper when it is installed with the main body 3, also cleans impurities from the top of the self-adhesive paper as it moves. When impurities accumulate between the adhesive paper and the paper, the blower 11 is activated to draw outside air into the exhaust pipe 10. The air is then blown towards the top of the adhesive paper through the exhaust pipe 10. The impurities on the top of the adhesive paper are affected by the air and blown up, moving with the air towards the exhaust hole 12 at the bottom of the cleaning box 6. The filter 13 on the exhaust hole 12 separates the impurities from the air, and the separated impurities fall to the bottom of the cleaning box 6. The collection pipe 15 allows the impurities at the bottom of the cleaning box 6 to enter the collection pipe 15 and be transported to the collection bag 16 located at the collection frame 14. The collection bag 16 collects the impurities, thus achieving the effect of cleaning both sides of the adhesive paper simultaneously and improving the cleaning effect of impurities on the adhesive paper.

[0038] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
