Description

Technical Field

[0001] This utility model relates to the field of gluing devices, specifically a gluing device for dual anti-counterfeiting laser transfer cardboard. Background Technology

[0002] The function of a glue-coating device for laser transfer cardboard is to apply adhesive to laser transfer cardboard so that the desired pattern or design can be transferred to the target surface when making printed materials or images. This device ensures that the adhesive is evenly applied to the surface of the cardboard, so that the pattern or design can be completely transferred to the target object during the laser transfer process to achieve the desired effect. This refers to a device for applying glue to laser transfer cardboard, which is usually used to make various printed materials or images.

[0003] Regarding patents for applying adhesive to laser transfer paper, a search revealed Chinese patent CN222984796U, which discloses an adhesive application device for dual anti-counterfeiting laser transfer paper. The device includes a support platform, a cover movably mounted on a mounting shell, support columns fixedly mounted on both the cover and the mounting shell, a first scraper below the cover, a U-shaped plate fixedly mounted on the top of the support columns, multiple first mounting grooves on the U-shaped plate, and a second scraper fixedly mounted on the top of the damper. This utility model utilizes the installation of both the first and second scrapers.

[0004] Although the above-mentioned device can achieve a scraping effect on both sides of the cardboard through the first and second scrapers set at the top and bottom, in actual use, the adhesive is prone to solidification during the application process, which can lead to problems such as particles or breaks in the adhesive layer, making it impossible to maintain stable adhesive quality. Utility Model Content

[0005] The purpose of this invention is to provide a gluing device for dual anti-counterfeiting laser transfer cardboard, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, a gluing device for dual anti-counterfeiting laser transfer cardboard is provided, comprising a frame, on the surface of which a secondary mounting seat and a primary mounting seat are respectively mounted. A limiting roller is movably mounted on the upper side of the secondary mounting seat, and a gluing roller is movably mounted on the upper side of the primary mounting seat. A glue container space is formed between the gluing roller and the limiting roller. A glue stirring mechanism is mounted in the glue container space. The glue stirring mechanism includes a drive wheel fixedly connected to the rotating shaft of the gluing roller, a driven wheel mounted on one side of the drive wheel, and a synchronous belt provided on the driven wheel and the drive wheel. An agitator is movably mounted inside the glue container space, and a drive seat is fixedly mounted on the top of the agitator.

[0007] Furthermore, a conveyor belt is movably mounted on the frame, and the surface of the conveyor belt is covered with cardboard. The cardboard is coated with adhesive by a rotating glue-applying roller and a limiting roller.

[0008] Furthermore, both sides of the coating roller are provided with baffles, which are circular. The two sets of baffles cover both sides of the adhesive space, and studs are fixedly provided on the bottom outer side of both sets of baffles. The bottom of the main mounting base is provided with waist holes.

[0009] Furthermore, the stud passes through the waist hole and is screwed to the nut for fixation. At the same time, a fixing rod is fixedly installed on the main mounting base. The fixing rod is U-shaped and its end is fixedly connected to the baffle.

[0010] Furthermore, the mixing mechanism includes a drive seat, a stirring seat, a guide rod, a lead screw, a driven wheel, a synchronous belt, and a driving wheel. A guide rod and a lead screw are respectively installed between the two sets of baffles, and the end of the guide rod is fixedly connected to the side wall of the baffle.

[0011] Furthermore, a guide rod is inserted into the guide hole on the lower side of the drive seat, and a lead screw is screwed into the screw hole on the upper side of the drive seat. The end of the lead screw is fixed to the shaft of the driven wheel, and the lead screw rotates using the glue-applying roller as the driving source.

[0012] Furthermore, the agitator is triangular in shape, and under the action of the drive seat and the lead screw, the agitator performs reciprocating linear motion along the length of the gel space.

[0013] Furthermore, a guide groove is provided on the outer circumference of the coating roller. The guide groove is spiral in shape and has a depth of 3-5 mm.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This solution utilizes a triangular agitator that, during reciprocating motion, ensures more thorough mixing and coverage of the adhesive in different areas of the adhesive container, reducing dead zones and ensuring uniform mixing of the adhesive throughout the container. This effectively prevents localized solidification and clumping of the adhesive due to prolonged standing, maintaining uniform fluidity and ensuring a continuous and uniform adhesive film adheres to the surface of the subsequent coating roller. This prevents uneven coating, particle formation, or breaks in the adhesive layer on the cardboard due to adhesive solidification, thus maintaining stable coating quality.

[0016] 2. This solution uses the coating roller as the drive source for the lead screw, which simplifies the overall structure of the equipment, reduces the investment and energy consumption of independent motors and other components, and lowers the manufacturing and operating costs of the equipment. It also ensures that the movement rhythm of the stirring seat is synchronized with the rotation rhythm of the coating roller, ensuring that the stirring frequency of the adhesive is matched with the coating speed, and avoiding the influence of excessively fast or slow stirring on the state of the adhesive.

[0023] Please see Figure 1-5 This utility model provides a gluing device for dual anti-counterfeiting laser transfer cardboard, including a frame 1. A secondary mounting seat 2 and a main mounting seat 21 are respectively installed on the surface of the frame 1. A limiting roller 4 is movably installed on the upper side of the secondary mounting seat 2, and a gluing roller 41 is movably installed on the upper side of the main mounting seat 21. A glue container space 5 is formed between the gluing roller 41 and the limiting roller 4. A glue stirring mechanism 10 is installed on the glue container space 5. The glue stirring mechanism 10 includes a drive wheel 107 fixedly connected to the rotating shaft of the gluing roller 41. A passive wheel 105 is installed on one side of the drive wheel 107. A synchronous belt 106 is provided on the passive wheel 105 and the drive wheel 107. An agitator 102 is movably installed inside the glue container space 5. A drive seat 101 is fixedly provided on the top of the agitator 102.

[0024] Working Principle: In actual use, after the adhesive is injected into the adhesive space 5 formed between the limiting roller 4 and the coating roller 41, the coating process is carried out in an orderly manner under the drive of an external motor, achieving precise coating of the paper 9 on the conveyor belt 8: Roller rotation and adhesive adhesion. After the external motor starts, it drives the limiting roller 4 and the coating roller 41 to rotate synchronously in a preset direction, usually in opposite directions. The rotation speed can be adjusted according to the conveying speed of the paper 9. At this time, the adhesive in the adhesive space 5 will be evenly adhered to the outer circumferential surface of the coating roller 41 through the adhesion between the roller surface and the adhesive during the rotation of the coating roller 41, forming a continuous adhesive layer with a preliminarily controllable thickness. During rotation, the limiting roller 4 maintains a fixed gap between its roller surface and the coating roller 41. When adhesive adheres to the surface of the coating roller 41, the limiting roller 4 performs a dual action of "scraping" and "squeezing" on the adhesive film on the surface of the coating roller 41. On the one hand, it scrapes off excess adhesive from the surface of the coating roller 41, allowing the excess adhesive to flow back into the adhesive space 5 for recycling. On the other hand, the fixed gap ensures that the final adhesive film thickness remaining on the surface of the coating roller 41 is uniform, avoiding problems of excessively thick or thin adhesive layers. At the same time, the conveyor belt 8 smoothly transports the cardboard 9 at a set speed, accurately transporting the cardboard 9 below the coating roller 41. When the adhesive surface of the cardboard 9 touches the coating roller 41... When the adhesive film on the surface comes into contact, under the pressure of the rotating roller and the viscosity of the adhesive itself, the adhesive film will be transferred completely and evenly to the designated coating area of ​​the cardboard 9, completing a single coating operation; subsequently, the cardboard 9 continues to be conveyed by the conveyor belt 8 to enter the next processing stage, such as lamination and drying; by controlling the fixed gap between the limiting roller 4 and the coating roller 41, the thickness of the adhesive film on the surface of the coating roller 41 can be precisely limited. Combined with the stable conveying speed of the conveyor belt 8, it can be ensured that the adhesive forms a uniform thickness, without bubbles or missed coatings on the surface of the cardboard 9, effectively avoiding quality problems such as weak bonding and edge curling of the cardboard 9 caused by uneven coating, and improving the product qualification rate; the adhesive space 5 not only It serves as a storage area for the adhesive and also enables the recycling of excess adhesive. Excess adhesive scraped off by the limiting roller 4 flows directly back to the adhesive container space 5 and re-participates in the coating process, avoiding adhesive waste. Compared to traditional manual coating or coating methods without a recycling structure, this design can improve the utilization rate of adhesive and significantly reduce the cost of adhesive consumables in the production process. The entire coating process is driven by an external motor to rotate the rollers and the conveyor belt 8 to transport the cardboard 9. No manual intervention is required for the coating operation, enabling continuous and large-scale cardboard 9 coating operations. Compared to manual coating, its coating efficiency can be improved, while reducing errors caused by manual operation, adapting to the high-efficiency production needs of industrial production lines.

[0025] In a preferred embodiment, a conveyor belt 8 is movably mounted on the frame 1, and the surface of the conveyor belt 8 is covered with cardboard 9. The cardboard 9 is coated with glue by a rotating glue-applying roller 41 and a limiting roller 4.

[0026] Both sides of the coating roller 41 are provided with baffles 6. The baffles 6 are circular. The two sets of baffles 6 cover both sides of the glue space 5 respectively. At the same time, studs are fixedly provided on the bottom outer side of the two sets of baffles 6. The bottom of the main mounting base 21 is provided with a waist hole 3.

[0027] The stud passes through the waist hole 3 and is screwed and fixed with the nut. At the same time, a fixing rod 7 is fixedly installed on the main mounting base 21. The fixing rod 7 is U-shaped and the end of the fixing rod 7 is fixedly connected to the baffle 6.

[0028] The mixing mechanism 10 includes a drive seat 101, a stirring seat 102, a guide rod 103, a lead screw 104, a driven wheel 105, a timing belt 106, and a drive wheel 107. The guide rod 103 and the lead screw 104 are respectively installed between the two sets of baffles 6, and the end of the guide rod 103 is fixedly connected to the side wall of the baffle 6.

[0029] A guide rod 103 is inserted into the guide hole on the lower side of the drive seat 101, and a lead screw 104 is screwed into the screw hole on the upper side of the drive seat 101. The end of the lead screw 104 is fixed to the shaft of the driven wheel 105, and the lead screw 104 is driven by the glue coating roller 41.

[0030] The stirring seat 102 is triangular in shape. Under the action of the drive seat 101 and the lead screw 104, the stirring seat 102 reciprocates linearly along the length of the glue-containment space 5.

[0031] In a preferred embodiment, a guide groove 411 is provided on the outer circumference of the coating roller 41. The guide groove 411 is spiral in shape and has a depth of 3 to 5 mm.

[0032] like Figure 1-5As shown: The lead screw 104 rotates with the coating roller 41 as the driving source, driving the agitator 102 to reciprocate linearly along the length of the glue container 5 in cooperation with the drive seat 101. The design of the transversely moving triangular agitator 102 agitating the glue liquid inside the glue container 5 is as follows: On the one hand, the triangular structure of the agitator 102 can form a more thorough stirring and coverage of the glue liquid in different areas of the glue container 5 during reciprocating motion, reducing dead zones in the glue liquid stirring, ensuring that the glue liquid in all parts of the glue container 5 can be evenly stirred, effectively preventing the glue liquid from solidifying and clumping due to prolonged standing, ensuring that the glue liquid always maintains uniform fluidity, and thus ensuring that the surface of the coating roller 41 can be coated with a continuous and uniform glue film. This avoids problems such as uneven glue coating on the coating roller 41 and particles or breaks in the glue layer of the paper 9 due to glue solidification, thus maintaining the glue coating quality. Stability; on the other hand, there is no need to set up an independent drive device for the agitator 102. Instead, the glue coating roller 41 is used as the drive source for the screw 104. This simplifies the overall structure of the equipment, reduces the investment and energy consumption of independent motors and other components, and lowers the equipment manufacturing and operating costs. It also allows the movement rhythm of the agitator 102 to be synchronized with the rotation rhythm of the glue coating roller 41, ensuring that the glue agitation frequency matches the glue coating speed. This avoids affecting the glue state due to agitation that is too fast or too slow. At the same time, the reciprocating movement of the agitator 102 along the length of the glue container 5 can also help the glue to be evenly distributed in the glue container 5, preventing the glue from concentrating in a certain area of ​​the glue container 5 due to gravity. This ensures that the glue coating roller 41 can always obtain a sufficient and uniform amount of glue from the glue container 5, further improving the stability and consistency of the glue coating on the paper 9 on the conveyor belt 8.

[0033] like Figure 1 and Figure 5As shown: When the adhesive in the adhesive space (5) adheres to the surface of the coating roller (41), the spiral guide groove (411) can guide the adhesive with the rotational power of the coating roller (41), so that the adhesive is evenly distributed on the outer circumference of the coating roller (41) along the spiral trajectory of the guide groove (411), avoiding local accumulation or distribution discontinuity of the adhesive on the surface of the coating roller (41), and further improving the continuity and uniformity of the adhesive film on the surface of the coating roller (41); at the same time, the spiral guide groove (411) can form a certain adhesive storage space on the surface of the coating roller (41), which can stably release the adhesive according to the coating requirements of the cardboard (9). Especially when the conveying speed of the conveyor belt (8) fluctuates slightly, the adhesive stored in the guide groove (411) can play a buffering role, ensuring that the adhesive is transferred to the surface of the cardboard (9). The glue application rate is kept constant to avoid fluctuations in the bonding quality of the cardboard (9) due to variations in glue application rate. In addition, the spiral guide groove (411) can reduce the relative sliding between the glue liquid and the surface of the glue roller (41) during the rotation of the glue roller (41), enhance the adhesion of the glue liquid on the roller surface, and prevent the glue liquid from being thrown off the surface of the glue roller (41) due to centrifugal force. With the control of the glue film thickness by the limit roller (4), the glue layer transferred to the surface of the cardboard (9) can not only be uniform in thickness, but also form a finer glue coating texture along the spiral direction of the guide groove (411), improving the tightness of the bonding between the glue layer and the cardboard (9). At the same time, the presence of the guide groove (411) also facilitates subsequent cleaning and maintenance, reduces the residual accumulation of glue liquid on the outer wall of the glue roller (41), and extends the service life of the glue roller (41).
