Description

Technical Field

[0001] This invention relates to the field of self-adhesive label preparation and processing technology, specifically to a composite self-adhesive label preparation and processing equipment and process. Background Technology

[0002] Self-adhesive labels, also known as pressure-sensitive labels, are composite materials made of paper, film, or special materials as the face stock, coated with adhesive on the back, and with silicone-coated release paper as the backing paper. Due to the variety of coating technologies, self-adhesive materials are produced in different grades. The development trend is from traditional roller coating and blade coating to high-pressure casting coating, in order to maximize the uniformity of the coating, avoid the generation of bubbles and pinholes, and ensure the coating quality. However, casting coating technology is not yet mature in China, and traditional roller coating is mainly used domestically.

[0003] Existing equipment suffers from uneven coating and glue overflow at the edges during the preparation and processing of composite self-adhesive labels. If this overflow is not cleaned promptly, it will affect the quality of subsequent products. Furthermore, existing equipment exhibits uneven and insufficiently tight bonding during the pressing process, resulting in air bubbles. These gaps and air bubbles affect the shelf life of the composite self-adhesive labels during storage, thus impacting their usability. Existing composite self-adhesive label processing methods are also slow, have low automation, are complex to operate, require large floor space, and have high production costs. Therefore, this invention designs a composite self-adhesive label preparation and processing equipment and process to solve the above problems. Summary of the Invention

[0013] Preferably, the cleaning mechanism includes a third spur gear, the center of which is fixedly connected to the first rotating shaft. One end of the third spur gear meshes with a rack, one end of which is fixedly connected to a sliding rod.

[0015] Preferably, it includes the following steps:

[0016] S1. First, start the first motor to rotate. The rotation of the first motor drives the first shaft to rotate, and the rotation of the first shaft drives the take-up roller to rotate. The take-up roller rotates to take up the self-adhesive label. The controller controls the first motor to rotate for five seconds and then stop for five seconds, repeating this process. This facilitates the subsequent processing of the composite self-adhesive label by using the set take-up roller to take up the composite self-adhesive label.

[0017] S2, at this time, the second motor is started to rotate. The rotation of the second motor drives the second rotating shaft to rotate, and the rotation of the second rotating shaft drives the glue-applying roller to rotate. At the same time, the rotation of the second rotating shaft drives the first spur gear to rotate, and the rotation of the first spur gear drives the second spur gear to rotate. The rotation of the second spur gear drives the third rotating shaft to rotate, and the rotation of the third rotating shaft drives the pressure roller to rotate. The glue-applying roller applies glue to the bottom of the sticker. A first scraper is set next to the glue-applying roller to scrape off excess glue from the surface of the glue-applying roller.

[0018] S3: By introducing hot air into the air intake pipe, the hot air passes through the hollow groove and the rotating rod into the interior of the curved plate. The curved plate adheres to the sticker, allowing the adhesive to dry quickly. The hot air enters from the upper end of the curved plate, passes through the plate, and flows out from the rear end. The torsion spring on the rotating rod drives the rotating rod to rotate clockwise. The clockwise rotation of the rotating rod causes the curved plate to move downward. The downward movement of the curved plate allows it to adhere tightly to the sticker, accelerating the bonding between the adhesive and the sticker.

[0019] S4, the hydraulic cylinder drives the sliding block to move downward, the sliding block moves downward, the pressure plate moves downward, the pressure plate moves downward, and the rollers move downward. The rollers press the non-adhesive adhesive tightly. By setting multiple sets of rollers at the lower end of the pressure plate, the movement of the sticker and the backing paper cooperates with the multiple sets of pressing rollers, so that the sticker and the backing paper can be tightly bonded together to form a composite non-adhesive. Using multiple rollers to squeeze the composite non-adhesive can ensure the dense effect of each layer, thereby ensuring the quality of the composite non-adhesive.

[0020] S5, when the equipment stops and the backing paper and sticker are removed, the roller needs to move upward. During the upward movement of the hydraulic cylinder, the sliding block moves upward, which in turn moves the pressure plate upward. The pressure plate then moves the roller upward, moving it away from the adhesive label. This upward movement of the roller makes it easier for workers to remove the adhesive label. The upward movement of the pressure plate moves the first connecting rod upward, which in turn moves the sliding plate upward. The sliding plate then moves the second slide rail upward, which in turn moves the curved plate upward. As the first connecting rod moves upward, it drives the second connecting rod upward. The upward movement of the second connecting rod moves the hollow groove away from the air inlet pipe, thus blocking the air inlet pipe. Through the linkage structure, when the multiple sets of pressing rollers move away from the sticker and the backing paper, the second connecting rod is driven to block the air inlet pipe. This allows the flow of hot air into the curved plate to be stopped in time when the equipment stops running, thereby saving energy. At the same time as the multiple sets of pressing rollers move away from the sticker and the backing paper, they also drive the curved plate upward. The upward movement of the curved plate compresses the torsion spring, and the upward movement of the curved plate moves away from the sticker, making it convenient to remove the sticker when the equipment stops.

[0021] S6. During the process of the roller pressing the base paper and the sticker together, glue will overflow from both sides. The second scraper at the top of the housing can scrape off the overflowing glue to avoid affecting the quality of the composite adhesive. While the first motor rotates, it drives the first rotating shaft to rotate. The first motor is controlled by the controller to rotate for a certain period of five seconds and then stop for five seconds, repeating this cycle. While the first rotating shaft rotates, it drives the third spur gear to rotate. The rotation of the third spur gear drives the rack to move downward. The downward movement of the rack drives the sliding rod to move downward. The downward movement of the sliding rod compresses the spring. During the downward movement of the sliding rod, it also drives the third connecting rod to move downward. The downward movement of the third connecting rod drives the cleaning block to move downward. The downward movement of the cleaning block cleans the glue remaining on the top of the second scraper.

[0022] The beneficial effects of this invention are:

[0023] (1) The composite self-adhesive preparation and processing equipment of the present invention introduces hot air into the air inlet pipe and enters the interior of the arc plate. The arc plate adheres to the sticker so that the adhesive dries quickly. The torsion spring set on the rotating rod will drive the rotating rod to rotate clockwise. The clockwise rotation of the rotating rod will drive the arc plate to move downward. The arc plate moves downward and adheres tightly to the sticker to accelerate the bonding between the adhesive and the sticker.

[0024] (2) The composite self-adhesive preparation and processing equipment of the present invention has multiple sets of rollers at the lower end of the pressure plate. The sticker and the backing paper move in coordination with the multiple sets of pressing rollers, so that the sticker and the backing paper can be tightly bonded together to form a composite self-adhesive. The use of multiple rollers to squeeze the composite self-adhesive can ensure the dense effect of each layer, thereby ensuring the quality of the composite self-adhesive.

[0025] (3) The composite self-adhesive preparation and processing equipment of the present invention, through the linkage structure, drives the second connecting rod to block the air inlet pipe when the multiple sets of pressing rollers move away from the sticker and the backing paper. In this way, when the equipment stops running, the hot air entering the arc plate can be stopped in time, thereby saving energy. At the same time as the multiple sets of pressing rollers move away from the sticker and the backing paper, the arc plate is also driven to move upward. The upward movement of the arc plate will compress the torsion spring and move away from the sticker, making it convenient to remove the sticker when the equipment stops.

[0026] (4) The composite self-adhesive preparation and processing equipment of the present invention can scrape off the overflowing glue by setting a second scraper at the upper end of the shell, so as to avoid affecting the quality of the composite self-adhesive.

[0027] (5) The composite self-adhesive preparation and processing equipment of the present invention, when the first motor rotates, drives the sliding rod to move downward. During the downward movement of the sliding rod, the third connecting rod is driven to move downward. The downward movement of the third connecting rod drives the cleaning block to move downward. The downward movement of the cleaning block will clean the glue residue on the upper end of the second scraper. When the first motor stops rotating, the spring will drive the cleaning block to reset.

The arc plate 33 is attached to the sticker 15 to allow the glue to dry quickly. The hot air enters the interior of the arc plate 33 from the top, passes through the arc plate 33 and flows out from the tail of the arc plate 33. The torsion spring 35 set on the rotating rod 32 will drive the rotating rod 32 to rotate clockwise. The clockwise rotation of the rotating rod 32 will drive the arc plate 33 to move downward. The arc plate 33 moves downward and fits tightly with the sticker 15, which accelerates the adhesion between the glue and the sticker 15.

[0048] Preferably, the pressing mechanism 4 includes a hydraulic cylinder 41, the side wall of which is fixedly connected to the housing 11. A sliding block 42 is fixedly connected to one end of the hydraulic cylinder 41. A first slide rail 43 is slidably connected to the side wall of the sliding block 42.

The downward movement of the sliding block 42 drives the pressure plate 44 to move downward. The downward movement of the pressure plate 44 drives the roller 45 to move downward. The downward movement of the roller 45 will press the non-adhesive adhesive tightly. By setting multiple sets of rollers 45 at the lower end of the pressure plate 44, the sticker 15 and the backing paper 14 move and cooperate with the multiple sets of pressing rollers 45. In this way, the sticker 15 and the backing paper 14 can be tightly bonded together to form a composite non-adhesive. Using multiple rollers 45 to compress the composite non-adhesive can ensure the dense effect of each layer, thereby ensuring the quality of the composite non-adhesive.

[0049] Preferably, the valve mechanism 5 includes a first connecting rod 51, one end of which is fixedly connected to the pressure plate 44, and a sliding plate 52 is rotatably connected to the lower end of the first connecting rod 51.

A second connecting rod 54 is fixedly connected to the side wall of the first connecting rod 51, one end of which has a hollow groove 55, and one end of which is slidably connected to the fixing block 31. When the equipment stops and the base paper 14 and sticker 15 are removed, the roller 45 needs to be driven to move upward. During the upward movement of the hydraulic cylinder 41, the sliding block 42 will be driven to move upward. The upward movement of the sliding block 42 will drive the pressure plate 44 to move upward, and the upward movement of the pressure plate 44 will drive the roller 45 to move upward. The upward movement of the roller 45 will move away from the composite self-adhesive, making it easier for workers to remove the composite self-adhesive.

The upward movement of the sliding rod 52 drives the second slide rail 53 to move upward. The upward movement of the second slide rail 53 drives the arc plate 33 to move upward. At the same time as the first connecting rod 51 moves upward, it drives the second connecting rod 54 to move upward.

Through the linkage structure, when the multiple sets of pressing rollers 45 move away from the sticker 15 and the base paper 14, it drives the second connecting rod 54 to block the air inlet pipe 34. This allows the hot air to be stopped in time when the equipment stops running, saving energy.

During the process of the roller 45 pressing the base paper 14 and the sticker 15 together, glue will overflow from both sides. A second scraper 68 is provided at the upper end of the housing 11 to scrape off the overflowing adhesive, thus avoiding affecting the quality of the composite adhesive. While the first motor 16 rotates, it drives the first rotating shaft 17 to rotate. The first motor 16 is controlled by the controller to rotate for a certain period of five seconds and then stop for five seconds, repeating this cycle. While the first rotating shaft 17 rotates, it drives the third spur gear 61 to rotate. The rotation of the third spur gear 61 drives the rack 62 to move downward. The downward movement of the rack 62 drives the sliding rod 63 to move downward. The downward movement of the sliding rod 63 compresses the spring 69. During the downward movement of the sliding rod 63, it also drives the third connecting rod 66 to move downward. The downward movement of the third connecting rod 66 drives the cleaning block 67 to move downward. The downward movement of the cleaning block 67 cleans the adhesive residue remaining at the upper end of the second scraper 68. When the first motor 16 stops rotating, the spring 69 will drive the cleaning block 67 to reset.

[0051] Working principle: When using this invention, the first motor 16 is started to rotate, which drives the first rotating shaft 17 to rotate, and the first rotating shaft 17 drives the take-up roller 18 to rotate. The take-up roller 18 rotates to take up the self-adhesive label. The controller controls the first motor 16 to rotate for five seconds and then stop for five seconds, repeating this process. This facilitates the subsequent processing of the composite self-adhesive label, and the take-up roller 18 is used to take up the composite self-adhesive label.

[0052] At this time, the second motor 21 is started to rotate, which drives the second shaft 22 to rotate. The rotation of the second shaft 22 drives the glue-applying roller 23 to rotate. At the same time, the rotation of the second shaft 22 drives the first spur gear 24 to rotate. The rotation of the first spur gear 24 drives the second spur gear 25 to rotate. The rotation of the second spur gear 25 drives the third shaft 26 to rotate. The rotation of the third shaft 26 drives the pressure roller 27 to rotate. The pressure roller 27 and the glue-applying roller 23 cooperate to better apply glue to the sticker 15. The glue is applied to the bottom of the sticker 15 by the glue-applying roller 23. A first scraper 28 is provided next to the glue-applying roller 23 to scrape off excess glue from the surface of the glue-applying roller 23.

[0053] Hot air is introduced into the air intake pipe 34. The hot air in the air intake pipe 34 passes through the hollow groove 55 and the rotating rod 32 into the interior of the arc plate 33. The arc plate 33 adheres to the sticker 15, allowing the adhesive to dry quickly. The arc shape of the arc plate 33 can better adhere to the sticker 15 while also saving floor space. The hot air enters the interior of the arc plate 33 from the top, passes through the arc plate 33, and flows out from the tail of the arc plate 33. The torsion spring 35 set on the rotating rod 32 will drive the rotating rod 32 to rotate clockwise. The clockwise rotation of the rotating rod 32 will drive the arc plate 33 to move downward. The downward movement of the arc plate 33 will make it fit tightly with the sticker 15, accelerating the adhesion between the adhesive and the sticker 15.

[0054] The hydraulic cylinder 41 drives the sliding block 42 to move downwards, which in turn drives the pressure plate 44 to move downwards. The pressure plate 44 then drives the rollers 45 to move downwards. The downward movement of the rollers 45 presses the non-adhesive adhesive tightly together. By setting multiple sets of rollers 45 at the lower end of the pressure plate 44, the sticker 15 and the backing paper 14 move in coordination with the multiple sets of pressing rollers 45. This allows the sticker 15 and the backing paper 14 to be tightly bonded together to form a composite non-adhesive. Using multiple rollers 45 to compress the composite non-adhesive ensures the density of each layer, thereby guaranteeing the quality of the composite non-adhesive.

[0055] When the equipment stops and the base paper 14 and sticker 15 are removed, the roller 45 needs to be moved upward. During the upward movement of the hydraulic cylinder 41, the sliding block 42 is moved upward, which in turn moves the pressure plate 44 upward. The pressure plate 44 then moves the roller 45 upward, moving it away from the adhesive label. This upward movement of the roller 45 makes it easier for workers to remove the adhesive label. When the pressure plate 44 moves upward, it moves the first connecting rod 51 upward, which in turn moves the sliding plate 52 upward. The sliding plate 52 then moves the second slide rail 53 upward, which in turn moves the curved plate 33 upward. As rod 51 moves upward, it drives the second connecting rod 54 upward. The upward movement of the second connecting rod 54 drives the hollow groove 55 away from the air inlet pipe 34, thus blocking the air inlet pipe 34. Through the linkage structure, when the multiple sets of pressing rollers 45 move away from the sticker 15 and the base paper 14, the second connecting rod 54 is driven to block the air inlet pipe 34. This allows the flow of hot air into the arc plate 33 to be stopped in time when the equipment stops running, thereby saving energy. At the same time as the multiple sets of pressing rollers 45 move away from the sticker 15 and the base paper 14, the arc plate 33 is also driven upward. The upward movement of the arc plate 33 will compress the torsion spring 35, and the upward movement of the arc plate 33 will move away from the sticker 15, making it convenient to remove the sticker 15 when the equipment stops.

[0056] During the pressing process of the roller 45 onto the base paper 14 and the sticker 15, glue will overflow from both sides. The overflowing glue can be scraped off by the second scraper 68 set at the upper end of the housing 11 to avoid affecting the quality of the composite self-adhesive. While the first motor 16 rotates, it drives the first rotating shaft 17 to rotate. The first motor 16 is controlled by the controller to rotate for a certain period of five seconds and then stop for five seconds, repeating this cycle. While the first rotating shaft 17 rotates, it drives the third spur gear 61 to rotate. The rotation of the third spur gear 61 drives the rack 62 to move downward. The downward movement of the rack 62 drives the sliding rod 63 to move downward. The downward movement of the sliding rod 63 will compress the spring 69. During the downward movement of the sliding rod 63, it also drives the third connecting rod 66 to move downward. The downward movement of the third connecting rod 66 drives the cleaning block 67 to move downward. The downward movement of the cleaning block 67 will clean the glue remaining at the upper end of the second scraper 68. When the first motor 16 stops rotating, the spring 69 will drive the cleaning block 67 to reset.

6. A process for preparing composite self-adhesive labels, characterized in that: Specifically, the following steps are included: S1, firstly start the first motor (16) to rotate. The rotation of the first motor (16) drives the first rotating shaft (17) to rotate. The rotation of the first rotating shaft (17) drives the take-up roller (18) to rotate. The take-up roller (18) rotates to take up the self-adhesive. The controller controls the first motor (16) to rotate for five seconds and then stop for five seconds, repeating this process. This makes it convenient to process the composite self-adhesive in the future. The set take-up roller (18) is used to take up the composite self-adhesive. S2, at this time, the second motor (21) is started to rotate. The rotation of the second motor (21) drives the second rotating shaft (22) to rotate. The rotation of the second rotating shaft (22) drives the glue-applying roller (23) to rotate. At the same time as the rotation of the second rotating shaft (22) drives the first spur gear (24) to rotate. The rotation of the first spur gear (24) drives the second spur gear (25) to rotate. The rotation of the second spur gear (25) drives the third rotating shaft (26) to rotate. The rotation of the third rotating shaft (26) drives the pressure roller (27) to rotate. Glue is applied to the bottom of the sticker (15) through the glue-applying roller (23). A first scraper (28) is set next to the glue-applying roller (23) to scrape off excess glue on the surface of the glue-applying roller (23). S3, by introducing hot air into the air inlet pipe (34), the hot air in the air inlet pipe (34) passes through the hollow groove (55) and the rotating rod (32) into the interior of the arc plate (33). The arc plate (33) is attached to the sticker (15) to allow the glue to dry quickly. The hot air enters the interior of the arc plate (33) from the top end. The hot air passes through the arc plate (33) and flows out from the tail end of the arc plate (33). The torsion spring (35) set on the rotating rod (32) will drive the rotating rod (32) to rotate clockwise. The clockwise rotation of the rotating rod (32) will drive the arc plate (33) to move downward. The arc plate (33) moves downward and fits tightly with the sticker (15) to accelerate the adhesion between the glue and the sticker (15). S4, the sliding block (42) is driven to move downward by the hydraulic cylinder (41), the sliding block (42) moves downward and drives the pressure plate (44) to move downward, the pressure plate (44) moves downward and drives the roller (45) to move downward, the roller (45) moves downward and presses the non-adhesive tightly. By setting multiple sets of rollers (45) at the lower end of the pressure plate (44), the sticker (15) and the backing paper (14) move and cooperate with the multiple sets of pressing rollers (45), so that the sticker (15) and the backing paper (14) can be tightly bonded together to form a composite non-adhesive. The use of multiple rollers (45) to squeeze the composite non-adhesive can ensure the dense effect of each layer, thereby ensuring the quality of the composite non-adhesive. S5, when the equipment stops and the backing paper (14) and sticker (15) are taken out, the roller (45) needs to be driven to move upward. During the upward movement of the hydraulic cylinder (41), the sliding block (42) will be driven to move upward. The upward movement of the sliding block (42) will drive the pressure plate (44) to move upward. The upward movement of the pressure plate (44) will drive the roller (45) to move upward. The upward movement of the roller (45) will move away from the composite self-adhesive. The upward movement of the roller (45) will make it easier for the worker to take out the composite self-adhesive. When the pressure plate (44) moves upward, it will drive the first connecting rod (51) to move upward. The upward movement of the first connecting rod (51) will drive the sliding plate (52) to move upward. The upward movement of the sliding plate (52) will drive the second slide rail (53) to move upward. The upward movement of the second slide rail (53) will drive the arc plate (33) to move upward. As the rod (51) moves upward, it drives the second connecting rod (54) to move upward. The upward movement of the second connecting rod (54) drives the hollow groove (55) away from the air inlet pipe (34), thus blocking the air inlet pipe (34). Through the linkage structure, when the multiple sets of pressing rollers (45) move away from the sticker (15) and the base paper (14), the second connecting rod (54) is driven to block the air inlet pipe (34). This way, when the equipment stops running, the hot air entering the arc plate (33) can be stopped in time, thus saving energy. As the multiple sets of pressing rollers (45) move away from the sticker (15) and the base paper (14), the arc plate (33) is also driven to move upward. The upward movement of the arc plate (33) will compress the torsion spring (35). The upward movement of the arc plate (33) will move away from the sticker (15), making it convenient to remove the sticker (15) when the equipment stops. S6, during the process of the roller (45) pressing the base paper (14) and the sticker (15) together, glue will overflow from both sides. The overflowing glue can be scraped off by the second scraper (68) set at the upper end of the housing (11) to avoid affecting the quality of the composite self-adhesive. While the first motor (16) rotates, it drives the first rotating shaft (17) to rotate. The first motor (16) is controlled by the controller to rotate for a certain period of five seconds and then stop for five seconds, repeating this cycle. While the first rotating shaft (17) rotates, it drives the third spur gear (61) to rotate. The rotation of the third spur gear (61) drives the rack (62) to move downward. The downward movement of the rack (62) drives the sliding rod (63) to move downward. The downward movement of the sliding rod (63) will compress the spring (69). During the downward movement of the sliding rod (63), it also drives the third connecting rod (66) to move downward. The downward movement of the third connecting rod (66) drives the cleaning block (67) to move downward. The downward movement of the cleaning block (67) will clean the glue remaining at the upper end of the second scraper (68).
