Description

Technical Field

[0001] This utility model relates to the field of cigarette packaging technology, specifically to a novel trademark paper gluing device for a YB25 packaging machine. Background Technology

[0002] In the label pasting process, the gluing process for label paper (cigarette carton and box packaging paper) is undoubtedly a crucial step. Currently, the common method for gluing label paper is as follows: the glue applicator first contacts the glue roller, using the rotation of the glue roller to pick up the glue from the glue cylinder and apply it to the glue applicator; then, the glue applicator spreads the glue onto the label paper traveling along the label conveyor channel by rotating counterclockwise. In this process, controlling the amount of glue applied is one of the core elements to ensure the quality of label pasting, which is mainly achieved by adjusting the distances between the scraper, glue roller, glue applicator, and backing roller; changes in the distance between each component directly affect the final amount of glue applied. However, existing label paper gluing technology has the following technical problems:

[0003] 1. The procedure for adjusting the amount of glue applied is cumbersome. Operators need to first adjust the gap between the glue applicator and the glue roller, and then adjust the gap between the scraper and the glue roller. The whole process requires repeated attempts and is highly dependent on the operator's experience, which consumes a lot of time and energy and seriously affects production efficiency.

[0004] 2. The open design of the glue cylinder causes the glue to evaporate quickly, making it prone to hardening and affecting its fluidity and moisture content. This directly leads to weak label adhesion and easy detachment, posing a serious quality risk to the product. Furthermore, the glue application roller and applicator are relatively heavy, and during long-term, high-frequency use, their mounting bearings are subjected to significant pressure and wear. Over time, the coaxiality of the mounting shafts gradually changes. Once the coaxiality deviates, the glue application roller and applicator cannot maintain a stable trajectory during rotation, resulting in uneven glue application. This causes some areas to have too much glue and others too little, significantly affecting the quality and stability of label adhesion and creating potential quality issues for subsequent product use.

[0005] 3. When cleaning the glue application device, components such as the glue scraper, glue application wheel, glue applicator, and glue receiving box need to be disassembled separately. However, these components are installed in a compact location with extremely limited operating space, and the tools and procedures required for disassembly are complex, demanding a high level of skill and patience from the operator. Even slight operational errors may damage the equipment or affect the correct installation of components.

[0006] To address the problems existing in current technologies, there is an urgent need to develop a new type of label paper gluing device. This device should be able to achieve one-click precise adjustment of the glue amount, optimize the sealing of the glue cylinder to prevent moisture loss, enhance the durability of key components to avoid coaxiality changes, and also have a quick-release structure for easy cleaning. This would solve existing problems such as cumbersome glue amount adjustment, easy glue curdling, uneven glue amount, and difficult cleaning. Summary of the Invention

[0007] To address the shortcomings of the existing technology, this utility model provides a novel label paper gluing device for a YB25 packaging machine. The device features a glue cylinder with an open top, housing a glue-applying wheel and a glue-applying assembly. A coupling drives the glue-applying wheel and assembly to apply glue collaboratively. The glue cylinder has an adjustable scraper and a pull-out glue-receiving box at the bottom. The end cap is semi-sealed to reduce glue contact with air. This optimizes the gluing process, improves gluing quality and efficiency, and the components are threaded for easy disassembly and cleaning, ensuring smooth equipment operation and cigarette quality.

[0008] Specifically, this utility model provides a novel label paper gluing device for a YB25 packaging machine, comprising: a glue cylinder, which is a cuboid with an open top and forms the main structure of the device; a glue-applying wheel and a glue-applying assembly are installed on the glue cylinder, which work together to apply glue to the label paper; a coupling is connected to one end of the glue-applying assembly to provide power for the entire gluing process, driving the glue-applying wheel and the glue-applying assembly to rotate; an adjustable scraper is provided inside the glue cylinder to scrape off excess glue from the surface of the glue-applying wheel; a pull-out glue-receiving box is installed at the bottom of the glue cylinder to store glue and collect glue that drips or flows down during the gluing and application process; and an end cap is installed on the glue cylinder to provide a semi-sealing effect, reducing the contact area between the glue and the outside air.

[0009] Furthermore, the glue application assembly includes: a connecting shaft, a mounting plate, and a glue application plate;

[0010] The two ends of the connecting shaft pass through the rubber cylinder and are fixedly installed on the rubber cylinder to form a two-end support, with one end connected to the coupling.

[0011] The mounting plate is installed on the connecting shaft. The mounting plate is provided with threaded holes. The glue applicator is installed on the mounting plate through the threaded holes and fastening bolts.

[0012] The glue applicator has a slotted hole with a fastening bolt inside. By loosening the fastening bolt, the glue applicator slides linearly along the slotted hole. After sliding to the desired position, the fastening bolt is tightened to adjust the position of the glue applicator.

[0013] Furthermore, the two ends of the upper rubber wheel pass through the rubber cylinder and are fixedly installed on the rubber cylinder, forming a two-end support.

[0014] Furthermore, a first gear is installed between the connecting shaft and the coupling; a second gear is installed on the outer wall of the rubber cylinder, and its installation position must ensure that it is in a suitable meshing position with the first gear and the second gear; a third gear is installed on the upper rubber wheel, and the first gear serves as the main drive, driving the upper rubber wheel to rotate through the meshing of the second gear and the third gear.

[0015] Furthermore, the glue cylinder is equipped with a scraper adjustment seat, which is fixedly installed in the glue cylinder at both ends by fastening bolts, and its shape is set as 'L'; the scraper adjustment seat is equipped with an adjustment bolt, which abuts against the scraper; the scraper is provided with a strip hole, and a fastening bolt is provided in the strip hole. When the adjustment bolt is rotated, it pushes the scraper to move in the strip hole. After moving to the appropriate position, the scraper is fixed by the fastening bolt, thereby realizing the adjustment of the gap between the scraper and the glue roller.

[0016] Furthermore, a lifting bracket is provided inside the glue cylinder. The lifting bracket is a scissor structure, which is composed of multiple rods connected by hinge points. When the bracket moves up and down, these rods will rotate around the hinge points, causing the height of the bracket to change.

[0017] The lifting support is connected in the middle by a screw rod with threads. When the screw rod is rotated, it will move axially. The movement of the screw rod will cause the scissor structure on both sides to unfold or retract, thereby realizing the raising or lowering of the lifting support.

[0018] A crank handle is installed on the screw, and the screw is rotated by turning the crank handle.

[0019] Furthermore, the glue receiving box is installed on the lifting bracket, and the height of the glue receiving box can be adjusted by the lifting bracket; when the equipment is running, the crank handle is turned to raise the lifting bracket to the preset position, so that the glue placed in the glue receiving box comes into contact with the glue application wheel, and the glue application wheel dips into the glue in the glue receiving box to complete the glue application work; when cleaning is required, the crank handle is turned to lower the lifting bracket to the bottom of the glue cylinder, and the glue receiving box is taken out for cleaning.

[0020] Furthermore, the glue cylinder wall is provided with an opening, through which the glue receiving box is pulled out;

[0021] The glue receiving box is equipped with a flat handle, which can be pulled out of the glue cylinder by pulling the flat handle.

[0022] Furthermore, the end cap is positioned above the glue cylinder, with a gap between it and the glue applicator. This end cap covers the glue applicator wheel and the glue scraper, forming a semi-sealed structure with the glue cylinder. This effectively reduces the contact between the glue and the outside air, while preventing dust and other impurities from entering the glue cylinder.

[0023] Furthermore, the end cap is provided with a detection hole and an adhesive inlet hole. The detection hole and adhesive inlet hole are positioned to avoid the glue-applying roller and the glue scraper, so that the detection device can directly observe the amount of adhesive in the glue box through the detection hole, and the adhesive can fall directly into the glue box through the adhesive inlet hole, avoiding being blocked by the glue-applying roller or the glue scraper.

[0024] Working principle:

[0025] 1. Operation process of the new label paper gluing device of YB25 packaging machine:

[0026] Preparation Stage: Before operation, first open the end cover 11 of the gluing device. Based on the required amount of glue for the label paper, loosen the fastening bolts connecting the scraper plate adjusting seat 41 and the scraper plate 4. Adjust the gap between the scraper plate 4 and the gluing wheel 2 by rotating the adjusting bolt 42 to a suitable state, ensuring that the scraper plate 4 only scrapes away excess glue from the surface of the gluing wheel 2, guaranteeing that the gluing wheel 2 provides an appropriate amount of glue. Then, tighten the fastening bolts to fix the adjusted scraper plate 4 onto the scraper plate adjusting seat 41. Next, according to the glue application requirements for the label paper, loosen the fastening bolts connecting the gluing plate 33 and the mounting plate 32, adjust the gluing plate 33 to the appropriate position, and then tighten the fastening bolts to fix it onto the mounting plate 32. Afterwards, close the end cover 11 onto the glue cylinder 1, and insert the detection tube and glue inlet tube into the detection hole 111 and glue inlet hole 112, respectively. Finally, turn the crank handle 102 to raise the lifting bracket 10 to the preset position, so that the glue-applying roller 2 is immersed in the glue-receiving box 9. Before starting the equipment, be sure to check and ensure that all components are securely installed.

[0027] Operation Phase: The glue quantity detection switch and glue flow switch are turned on. Glue is delivered through the latex tube to the glue inlet hole 112 and falls into the glue receiving box 9. The glue quantity detection device detects the glue quantity through the detection hole 111. When the glue contacts the glue application wheel 2 and the glue quantity reaches the preset position, a signal is sent to the controller. The controller closes the glue flow switch, and the glue inlet channel is immediately closed, stopping glue application. At this time, the glue application device is started. The coupling 10 acts as the power source, driving the connecting shaft 31 to rotate, simultaneously driving the first gear 6 and the glue applicator 33 to rotate. The first gear 6 acts as the main drive, meshing with the second gear 7, thereby driving the second gear 7 to rotate. The second gear 7 meshes with the third gear 8, thus driving the third gear 8 to rotate. Since the third gear 8 is mounted on the glue application wheel 2, it drives the glue application wheel 2 to rotate. The rotating gluing roller 2 gradually dips into the glue receiving box 9 to pick up glue. When the gluing roller 2 finishes picking up glue and rotates to the position where it contacts the glue scraper 4, the glue scraper 4 starts working and scrapes away excess glue. After the gluing roller 2 passes the position of the glue scraper 4, it continues to rotate and contacts the glue applicator 33. The glue applicator 33 picks up the glue on the gluing roller 2, and as the glue applicator 33 continues to rotate, it applies the glue to the label paper, completing the gluing process.

[0028] 2. Cleaning process of the new label paper gluing device of YB25 packaging machine:

[0029] When the gluing device needs cleaning, turn off the power source of the gluing device and stop the equipment operation. First, remove the detection tube and glue inlet tube from the end cover 11, then remove the end cover 11 from the glue cylinder 1. Next, remove the scraper 4 from the scraper adjustment seat 41. Then, by turning the crank handle 102, lower the lifting bracket 10 to the bottom of the glue cylinder 1. Finally, by pulling the flat handle 91, pull out the glue receiving box 9 from the glue cylinder 1 to perform the overall cleaning work.

[0030] The gluing device offers significant advantages in operation and cleaning. During operation, the adjustable scraper 9 precisely controls the amount of glue applied, preventing over- or under-application, improving packaging quality, and reducing defect rates. Simultaneously, multi-stage gear transmission ensures stable power transmission, guaranteeing consistency and continuity in the gluing process. The glue quantity detection device, working in conjunction with the controller, achieves automated glue quantity control, reducing manual intervention and improving production efficiency. During cleaning, components such as the end cap 11, scraper 4, and glue receiving box 9 are easily disassembled, facilitating deep cleaning by operators. This prevents glue from drying and impurities from accumulating, ensuring equipment hygiene and maintaining the stability and accuracy of gluing. It also reduces downtime due to equipment malfunctions, extends equipment lifespan, and comprehensively improves production efficiency and product quality.

[0031] Beneficial effects:

[0032] 1. This utility model provides a stable main support structure for the entire device by setting the glue cylinder as a cuboid with an open top. The glue-applying roller and the glue-applying assembly pass through the glue cylinder at both ends and are fixedly installed, forming a two-end support. This two-end support can better distribute the stress generated by the components during high-speed operation, preventing deformation or damage to the components due to excessive force at a single point. At the same time, this structure also facilitates precise concentricity adjustment, ensuring smoother rotation of the glue-applying roller and the glue-applying assembly, reducing offset and vibration caused by eccentric rotation, further improving the reliability and stability of equipment operation, reducing shaking and wear, and extending the service life of the equipment.

[0033] 2. This utility model uses a semi-sealed connection between the end cap and the glue cylinder, and is installed on top of the glue cylinder in a simple way. This not only makes it easy to remove during cleaning, but also effectively reduces the contact between the glue and the outside air, prevents dust and other impurities from entering the glue cylinder, and facilitates the operator to inspect and maintain the inside of the glue cylinder.

[0034] 3. The glue applicator plate in this utility model is installed on the mounting plate via threaded holes and fastening bolts, and the glue applicator plate is provided with a slotted hole. Loosening and tightening the fastening bolts allows the glue applicator plate to slide linearly along the slotted hole, so that the position of the glue applicator plate can be flexibly adjusted according to different glue application requirements of the label paper, ensuring that the glue can be accurately and evenly applied to the label paper, thereby improving the packaging quality.

[0035] 4. This utility model features a scraper adjustment seat inside the glue cylinder, which abuts against the scraper via an adjusting bolt. The scraper has a slotted hole. Rotating the adjusting bolt moves the scraper within the slotted hole, precisely adjusting the gap between the scraper and the gluing roller. During the preparation stage, based on the required glue amount for the label paper, the gap between the scraper and the gluing roller is adjusted to a suitable level, ensuring that the scraper only removes excess glue from the surface of the gluing roller, guaranteeing that the gluing roller provides the appropriate amount of glue, avoiding excessive or insufficient glue application, improving packaging quality, and reducing the defect rate.

[0036] 5. In this utility model, a first gear is installed between the connecting shaft and the coupling, a second gear is installed on the outer wall of the glue cylinder, and a third gear is installed on the glue-applying wheel. The first gear serves as the main drive, meshing with the second and third gears in sequence to drive the glue-applying wheel to rotate. This multi-stage gear meshing transmission method ensures the stability of power transmission, guarantees the consistency and continuity of the glue-applying process, avoids uneven glue application caused by unstable power transmission, and improves the product qualification rate.

[0037] 6. The lifting bracket inside the glue cylinder of this utility model has a scissor structure. Rotating the crank handle on the screw can raise or lower the lifting bracket, thereby adjusting the height of the glue receiving box. When the equipment is running, the lifting bracket is raised to the preset position so that the glue-applying wheel dips into the glue in the glue receiving box for glue application. When cleaning, the lifting bracket is lowered to the bottom of the glue cylinder for easy removal of the glue receiving box. The operation is simple and efficient, reducing the time and labor costs required for cleaning.

[0038] 7. The end cap of this utility model is provided with a detection hole and a glue inlet hole. The glue quantity detection device can directly observe the amount of glue in the glue receiving box through the detection hole. When the glue contacts the glue feeding roller and the glue quantity reaches the preset position, a signal is sent to the controller. The controller closes the glue flow switch, thereby closing the glue inlet channel and stopping glue feeding. The cooperation between the glue quantity detection device and the controller realizes automated glue quantity control, reduces manual intervention, improves production efficiency, ensures the stability of glue supply, and avoids production disruptions due to glue quantity issues.

[0039] 8. This utility model uses bolts to fix various key components. The glue applicator is fixed to the mounting plate by bolts, and the glue scraper adjustment seat is fixed inside the glue cylinder by bolts. The bolt connection method provides strong connection strength, ensuring that the components will not loosen or shift due to vibration or force during high-speed operation of the equipment. This stable connection allows the entire glue application device to withstand large working loads during operation, ensuring the accurate and stable relative positions of components such as the glue application wheel, glue applicator assembly, and glue scraper, providing a reliable structural foundation for achieving precise glue application.

[0040] 9. This utility model features multiple components that can be easily disassembled, which is of great significance for cleaning the equipment. During cleaning, the scraper can be removed from the scraper adjustment seat, and components such as the glue box, glue application wheel, and glue cylinder can be cleaned separately, thoroughly removing residual glue, dust, and other impurities from the surface and interior of the components. Compared to some integrated designs that are difficult to disassemble, the detachable and washable nature of this device ensures that cleaning can reach every detail, avoiding the problem of glue drying and hardening on the components, ensuring the cleanliness of the equipment, and helping to maintain the quality and stability of glue application.

[0041] 10. The detachable design of this utility model makes equipment maintenance much easier. For faulty or damaged parts, disassembly allows for quick location of the problem, checking for wear on the glue applicator, flexibility of the glue scraper adjustment mechanism, and proper functioning of the lifting bracket screws, etc. Damaged parts can be disassembled and replaced individually without requiring large-scale repairs or replacements of the entire equipment, thus reducing maintenance costs and repair time.

[0061] The technical solution will now be described in detail with reference to the accompanying drawings of the embodiments of this utility model.

[0062] Example 1

[0063] like Figure 1 , 10As shown, a new type of trademark paper gluing device for a YB25 packaging machine includes: a glue cylinder 1, a glue-applying wheel 2, a glue-applying assembly 3, a connecting shaft 31, a mounting plate 32, a glue-applying plate 33, a waist-shaped hole 34, a glue scraper 4, a glue scraper adjusting seat 41, an adjusting bolt 42, a strip-shaped hole 43, a coupling 5, a first gear 6, a second gear 7, a third gear 8, a glue receiving box 9, a flat handle 91, a lifting bracket 10, a screw 101, a crank handle 102, an end cap 11, a detection hole 111, a glue inlet hole 112, a fastening bolt 14, and an opening 16.

[0064] like Figure 8 As shown, the glue cylinder 1 is a cuboid with an open top, which is the main structure of the device;

[0065] like Figure 8 As shown, the glue roller 2 passes through the glue cylinder 1 at both ends and is fixedly installed on the glue cylinder 1 to form a two-end support. It works in conjunction with the glue applicator 3 to apply glue 15 to the label paper.

[0066] like Figure 8 As shown, the connecting shaft 31 on the glue applicator 3 passes through the glue cylinder 1 at both ends and is fixedly installed on the glue cylinder 1 to form a two-end support. One end of the shaft is connected to the coupling 5 to drive the upper glue wheel 2 and the glue applicator 3 to rotate. The mounting plate 32 is installed on the connecting shaft 31. The mounting plate 32 is provided with threaded holes. The glue applicator 33 is installed on the mounting plate 32 through the threaded holes and fastening bolts. The glue applicator 33 is provided with a waist-shaped hole 34. The waist-shaped hole 34 is equipped with a fastening bolt. By loosening the fastening bolt, the glue applicator slides linearly along the waist-shaped hole. After sliding to the desired position, the fastening bolt is tightened to adjust the position of the glue applicator 33.

[0067] like Figure 2 , 8 As shown, a first gear 6 is installed between the connecting shaft 31 and the coupling 5; a second gear 7 is installed on the outer wall of the rubber cylinder 1, and its installation position must ensure that it is in a suitable meshing position with the first gear 6 and the second gear 7; a third gear 8 is installed on the upper rubber wheel 2. The first gear 6 serves as the main drive, and through the meshing of the second gear 7 and the third gear 8, it drives the upper rubber wheel 2 to rotate.

[0068] like Figure 8 , 9As shown, the scraper 4 is set inside the glue cylinder 1 and is adjustable, used to scrape off excess glue 15 from the surface of the glue roller; the scraper adjusting seat 41 is set inside the glue cylinder 1, and its two ends are fixedly installed inside the glue cylinder 1 by fastening bolts, and its shape is set as 'L'; the adjusting bolt 42 is installed on the scraper adjusting seat 41 and abuts against the scraper 4; the scraper 4 is provided with a strip hole 43, and a fastening bolt is provided in the strip hole 43. When the adjusting bolt 42 is rotated, it pushes the scraper 4 to move in the strip hole 43. After moving to the appropriate position, the scraper 4 is fixed by the fastening bolt, thereby realizing the adjustment of the gap between the scraper 4 and the glue roller 2.

[0069] like Figure 8 As shown, the glue receiving box 9 is installed at the bottom of the glue cylinder 1 and is designed to be pull-out. It is used to store glue 15 and collect glue 15 that drips or flows down during the glue application and gluing process.

[0070] like Figure 9 As shown, the lifting bracket 10 is housed within the rubber cylinder 1. The lifting bracket 10 is a scissor structure, consisting of multiple rods connected by hinge points. When the bracket moves up and down, these rods rotate around the hinge points, causing the height of the bracket to change. The lifting bracket 10 is connected to a screw 101 in the middle. The screw 101 has threads. When the screw 101 is rotated, it moves axially. The movement of the screw 101 causes the scissor structures on both sides to unfold or retract, thereby raising or lowering the lifting bracket 10. A crank handle 102 is mounted on the screw 101. Rotating the crank handle 102 causes the screw 101 to rotate.

[0071] like Figure 9 As shown, the glue receiving box 9 is installed on the lifting bracket 10, and the height of the glue receiving box 9 can be adjusted by the lifting bracket 10. During the operation of the equipment, the crank handle 102 is turned to raise the lifting bracket 10 to the preset position, so that the glue 15 placed in the glue receiving box 9 comes into contact with the glue application wheel 2. The glue application wheel 2 picks up the glue 15 in the glue receiving box 9 to achieve the glue application work. When cleaning is required, the crank handle 102 is turned to lower the lifting bracket 10 to the bottom of the glue cylinder 1, and the glue receiving box 9 is taken out for cleaning.

[0072] like Figure 10 As shown, the glue cylinder 1 has an opening 16 on its wall, through which the glue receiving box 9 is pulled out; the glue receiving box 9 is provided with a flat handle 91, which is pulled out of the glue cylinder 1 by pulling the flat handle 91.

[0073] like Figure 1 As shown, the end cap 11 is located above the glue cylinder 1 and has a gap between it and the glue applicator 33. This end cap 11 can cover the glue roller 2 and the glue scraper 4, and forms a semi-sealed structure with the glue cylinder 1.

[0074] like Figure 1 , 3 As shown, the detection hole 111 and the glue inlet hole 112 are provided on the end cap 11. The detection hole 111 and the glue inlet hole 112 are positioned to avoid the glue application roller 2 and the glue scraper 4, so that the detection device can directly observe the amount of glue 15 in the glue receiving box 9 through the detection hole 111, and the glue 15 can fall directly into the glue receiving box 9 through the glue inlet hole 112, avoiding being blocked by the glue application roller 2 or the glue scraper 4.

[0075] like Figure 10 As shown, the glue receiving box 9 is made of plastic. Plastic is relatively lightweight, and when it needs to be raised or lowered, the operation of the lifting bracket does not place excessive additional load on the lifting mechanism, ensuring the stable operation of the lifting bracket. At the same time, the lighter weight also facilitates manual operation by the operator, allowing for easy movement of the glue receiving box during cleaning and reducing labor intensity. The relatively smooth surface of the plastic material results in lower adhesion of the glue 15, which helps reduce glue 15 residue during cleaning, making cleaning easier.

[0076] like Figure 3 , 4 As shown, the operation process of the new label paper gluing device of the YB25 packaging machine is as follows:

[0077] Preparation Stage: Before starting work, first open the end cover 11 of the gluing device. According to the required amount of glue for the cigarette soft pack label paper 17, loosen the fastening bolts connecting the scraper plate adjusting seat 41 and the scraper plate 4. By rotating the adjusting bolt 42, adjust the gap between the scraper plate 4 and the gluing wheel 2 to a suitable state, ensuring that the scraper plate 4 only scrapes off excess glue 15 from the surface of the gluing wheel 2, and ensuring that the gluing wheel 2 provides an appropriate amount of glue 15. Then, tighten the fastening bolts to fix the adjusted scraper plate 4 on the scraper plate adjusting seat 41. Next, according to the glue application requirements of the three side points of the cigarette soft pack label paper 17, loosen the fastening bolts connecting the glue applicator 33 and the mounting plate 32, adjust the glue applicator 33 to the corresponding positions of the three side points of the cigarette soft pack label paper 17, and then tighten the fastening bolts to fix it on the mounting plate 32. Next, place the end cap 11 onto the glue cylinder 1, and insert the detection tube 12 and the glue inlet tube 13 into the detection hole 111 and the glue inlet hole 112, respectively. Finally, turn the crank handle 102 to raise the lifting bracket 10 to the preset position, so that the glue inlet wheel 2 is immersed in the glue receiving box 9. Before starting the equipment, be sure to check and ensure that all components are securely installed.

[0078] Operation Phase: The glue quantity detection switch and glue flow switch are turned on. Glue 15 is delivered through the latex tube to the glue inlet hole 112 and falls into the glue receiving box 9. The glue quantity detection device detects the glue quantity through the detection hole 111. When glue 15 contacts the glue feeding wheel 2 and the glue quantity reaches the preset position, a signal is sent to the controller. The controller closes the glue flow switch, and the glue feeding channel is immediately closed, stopping the glue feeding. At this time, the glue feeding device is started. The coupling 10 acts as the power source, driving the connecting shaft 31 to rotate, simultaneously driving the first gear 6 and the glue applicator 33 to rotate. The first gear 6 acts as the main drive, meshing with the second gear 7, thereby driving the second gear 7 to rotate. The second gear 7 meshes with the third gear 8, thus driving the third gear 8 to rotate. Since the third gear 8 is mounted on the glue feeding wheel 2, it drives the glue feeding wheel 2 to rotate. The rotating gluing roller 2 gradually immerses itself in the glue receiving box 9 to pick up glue 15. When the gluing roller 2 finishes picking up glue and rotates to the position where it contacts the scraper plate 4, the scraper plate 4 starts working to scrape off the excess glue 15. After the gluing roller 2 passes the scraper plate 4, it continues to rotate and contacts the applicator plate 33. The applicator plate 33 picks up the glue 15 on the gluing roller 2. As the applicator plate 33 continues to rotate, the glue 15 is applied to the cigarette soft pack label paper 17, completing the gluing process.

[0079] Cleaning Stage: When the gluing device needs cleaning, turn off the power source of the gluing device and stop the equipment operation. First, remove the detection tube 12 and the glue inlet tube 13 from the end cover 11, then remove the end cover 11 from the glue cylinder 1.
