Description

Technical Field

[0001] This utility model relates to the field of adhesive application equipment technology, specifically an adhesive application device for processing antibacterial and formaldehyde-removing wall coverings. Background Technology

[0002] As people's demands for environmental protection and aesthetics in interior decoration increase, antibacterial and formaldehyde-removing wall coverings are becoming increasingly popular in the market. The gluing device is a key piece of equipment used in the wall covering production process to accurately apply antibacterial and formaldehyde-removing adhesive to the wall covering. Its core function is to ensure that the adhesive adheres to the wall covering evenly and in the right amount, thus ensuring good adhesion performance and environmental protection function of the wall covering.

[0003] Application No. 202221505297.3 discloses an adhesive application device for processing antibacterial and formaldehyde-removing wallcoverings. This utility model proposes an adhesive application device for processing antibacterial and formaldehyde-removing wallcoverings, which is equipped with a second rotating column and an adhesive application wheel. The wallcovering is driven along the second rotating column and the adhesive application wheel. The adhesive application wheel drives the adhesive inside the receiving groove to rotate to the lower surface of the wallcovering and evenly apply it to the lower surface of the wallcovering. Then it is transported to the bottom of the third rotating wheel. The adhesive application of the wallcovering is completed by bonding the wallcovering with the oil film. The adhesive application speed is fast and the efficiency is high.

[0004] The aforementioned device cannot control the amount of water applied during use. Due to the significant differences in adhesive application requirements for wall coverings of different thicknesses and materials, thin non-woven wall coverings require less adhesive, while thick woven wall coverings require more adhesive to ensure a firm bond. When the device cannot control the amount of adhesive applied, too much adhesive not only causes waste but also makes the wall covering surface uneven and may even cause adhesive seepage. Too little adhesive, on the other hand, will cause the wall covering to not adhere firmly, resulting in hollow areas and curling edges, which greatly affects the quality and performance of the wall covering. Therefore, we have proposed an adhesive application device for processing antibacterial and formaldehyde-removing wall coverings. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an adhesive application device for antibacterial and formaldehyde-removing wallcoverings. This solves the problem of the inability to control the amount of adhesive applied by the aforementioned devices. Because wallcoverings of different thicknesses and materials have significantly different adhesive requirements—thin non-woven wallcoverings require less adhesive, while thicker woven wallcoverings require more to ensure a firm bond—excessive adhesive application not only leads to waste but also causes unevenness on the wallcovering surface and even adhesive seepage. Conversely, insufficient adhesive results in poor adhesion, causing blistering and curling edges, significantly impacting the quality and performance of the wallcovering.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution: an adhesive application device for processing antibacterial and formaldehyde-removing wall coverings, comprising a work box, a placement slot on the work box, a first support frame fixedly connected to the top of the work box, a first rotating roller rotatably connected to the top of the first support frame, a second support frame fixedly connected to the top of the work box, a third support frame fixedly connected to the side of the top of the work box away from the first support frame, a motor fixedly connected to the side wall of the second support frame, an adhesive roller fixedly connected to the output end of the motor, the adhesive roller rotatably connected to the inner wall of the second support frame, a scraper provided on the second support frame, and scraping components provided on both sides of the top of the work box, the scraper scraping off excess adhesive on the adhesive roller.

The screw is threadedly connected to the inner wall of the fixed box and extends to the outside of the fixed box. The side wall of the push block is rotatably connected to one side of the screw. The push column is slidably connected to the inner wall of the fixed box. The inclined groove is formed on the push column and matches one end of the push block. One end of the scraper is fixedly connected to the side wall of the push column. The spring is fixedly connected between the side wall of the push column and the side wall of the fixed box and is located inside the fixed box.

[0008] Preferably, a first toothed disc is fixedly sleeved on the outer wall of one end of the rubber roller, a rotating roller is rotatably connected to the inner wall of the top of the second support frame, a second toothed disc is fixedly sleeved on the outer wall of one end of the rotating roller, the outer wall of the first toothed disc meshes with the outer wall of the second toothed disc, and the rotating roller is located at the top of the rubber roller.

[0009] Preferably, a fourth rotating roller is rotatably connected to the inner wall of the top end of the third support frame.

[0010] Preferably, a cylinder is fixedly connected to the top of the work box, and a movable frame is fixedly connected to the output end of the cylinder.

[0013] Compared with the prior art, this utility model provides an adhesive application device for processing antibacterial and formaldehyde-removing wall coverings, which has the following beneficial effects:

[0014] 1. This antibacterial and formaldehyde-removing wallcovering processing gluing device is highly efficient. Driven by a motor, the glue roller and its meshing rotating roller work in tandem, significantly increasing gluing speed compared to traditional manual gluing methods. It can quickly meet the needs of large-scale wallcovering production, improving production efficiency and reducing labor costs. The uniquely designed scraper and scraping components allow operators to precisely adjust the distance between the scraper and glue roller by simply rotating the screw, based on the specific characteristics of the wallcovering, such as the need for less glue for thin non-woven wallcoverings and more glue for thick woven wallcoverings. This effectively avoids problems such as waste from excessive glue, uneven wallcovering surfaces, and glue seepage, as well as quality defects such as weak adhesion, hollow spots, and curling edges caused by insufficient glue, ensuring stable and reliable wallcovering quality.

[0015] 2. The adhesive application device for antibacterial and formaldehyde-removing wall coverings has a heating plate fixedly connected to the bottom wall of the placement tank.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 An adhesive application device for antibacterial and formaldehyde-removing wallcoverings includes a work box 1 with a placement slot 2. A first support frame 4 is fixedly connected to the top of the work box 1, and a first rotating roller 5 is rotatably connected to the top of the first support frame 4. A second support frame 6 is fixedly connected to the top of the work box 1, and a third support frame 13 is fixedly connected to the side of the top of the work box 1 away from the first support frame 4. A motor 7 is fixedly connected to the side wall of the second support frame 6, and an adhesive roller 8 is fixedly connected to the output end of the motor 7. The adhesive roller 8 is rotatably connected to the inner wall of the second support frame 6. A scraper 21 is provided on the second support frame 6, and scraping components are provided on both sides of the top of the work box 1. The scraper 21 scrapes off excess adhesive on the adhesive roller 8. The operator places one end of the wallcovering on the first rotating roller 5, then carefully pulls the wallcovering to smoothly pass through the gap between the bottom of the adhesive roller 8 and the rotating roller 11, and finally precisely places it onto the fourth rotating roller 14 to complete the wallcovering installation. At the same time, a suitable adhesive with antibacterial and formaldehyde-removing properties is poured into the placement slot 2 of the work box 1.

[0023] The scraping assembly also includes a spring 25, a fixed box 12, a screw 26, a push block 22, a push column 23, and a slanted groove 24. The fixed box 12 is fixedly connected to both sides of the top of the work box 1. Limiting frames 20 are fixedly connected to both sides of the top of the work box 1. The outer wall of the scraper 21 is slidably connected to the inner wall of the limiting frame 20. The screw 26 is threadedly connected to the inner wall of the fixed box 12 and extends to the outside of the fixed box 12. The side wall of the push block 22 is rotatably connected to one side of the screw 26. The push column 23 is slidably connected to the inner wall of the fixed box 12. The slanted groove 24 is formed in the push block 25. On the moving column 23, the inclined groove 24 matches one end of the push block 22, the scraper 21 is fixedly connected to one end of the push column 23 side wall, and the spring 25 is fixedly connected between the side wall of the push column 23 and the side wall of the fixed box 12 and located inside the fixed box 12. When it is necessary to precisely adjust the distance between the scraper 21 and the rubber roller 8 according to the material and thickness of the wallpaper, the operator manually rotates the screw 26. The screw 26 moves outward along the thread on the inner wall of the fixed box 12, gradually moves away from the fixed box 12, and extends outward from the fixed box 12. During this process, the screw 26 drives the push block 22, which is rotatably connected to it, to leave the inclined groove 24 on the push column 23. The spring 25, which was originally in a compressed state, instantly resets, releasing its elastic force and driving the push column 23 to slide along the inner wall of the fixed box 12 to the outer side of the fixed box 12. The push column 23 then drives the scraper 21, which is fixedly connected to its side wall, to approach the glue roller 8. The scraper 21 can then scrape off excess glue on the glue roller 8, achieving precise control of the glue application amount. Conversely, when it is necessary to move the scraper 21 away from the glue roller 8, the screw 26 is rotated in the opposite direction. The screw 26 rotates into the fixed box 12. Under the guidance of the inclined groove 24, the push block 22 pushes the push column 23 to retract into the fixed box 12. The spring 25 is compressed again, and the scraper 21... The increased distance between the glue roller 8 and the wall covering roller 8 enables efficient glue application. Driven by the motor 7, the glue roller 8 and its meshing rotating roller 11 work in tandem, significantly improving the glue application speed compared to traditional manual glue application. This allows for rapid fulfillment of large-scale wallcovering production needs, increasing production efficiency and reducing labor costs. The uniquely designed scraper 21 and scraping components allow operators to precisely adjust the distance between the scraper 21 and the glue roller 8 by simply rotating the screw 26, based on the specific characteristics of the wallcovering, such as the need for less glue for thin non-woven wallcoverings and more glue for thick woven wallcoverings. This effectively avoids problems such as waste due to excessive glue, uneven wallcovering surface, and glue seepage, as well as quality defects such as weak adhesion, hollow areas, and curling edges caused by insufficient glue, ensuring stable and reliable wallcovering quality.

[0024] A first toothed disc 9 is fixedly sleeved on the outer wall of one end of the glue roller 8, and a rotating roller 11 is rotatably connected to the inner wall of the top of the second support frame 6. A second toothed disc 10 is fixedly sleeved on the outer wall of one end of the rotating roller 11. The outer walls of the first toothed disc 9 and the second toothed disc 10 mesh with each other. The rotating roller 11 is located at the top of the glue roller 8. The first toothed disc 9 fixedly sleeved on the outer wall of one end of the glue roller 8 meshes with the second toothed disc 10 on the outer wall of one end of the rotating roller 11. This structural design is ingenious. When the motor 7 drives the glue roller 8 to rotate, the rotating roller 11 rotates synchronously through the meshing transmission of the toothed discs, and the two work together. On the one hand, the rotating roller 11 can help the glue roller 8 to better and more evenly apply the glue to the lower surface of the wallpaper, preventing glue accumulation or uneven application. On the other hand, this linkage method makes the glue application process more stable and efficient. Compared with single-roller glue application, it greatly improves the uniformity of glue distribution on the wallpaper and ensures the quality of wallpaper pasting.

[0025] The inner wall of the top of the third support frame 13 is rotatably connected to the fourth rotating roller 14; it is mainly responsible for receiving the wallpaper that has been initially glued between the glue roller 8 and the rotating roller 11, providing stable support for the wallpaper, ensuring that the wallpaper is smoothly transmitted when it enters subsequent processes such as oil film bonding, and preventing problems such as wrinkles or shifts due to uneven tension or unstable support, thus ensuring the quality of wallpaper processing.

[0026] A cylinder 15 is fixedly connected to the top of the work box 1, and a movable frame 16 is fixedly connected to the output end of the cylinder 15. A movable roller 17 is rotatably connected to the inner wall of the movable frame 16. A fourth support frame 19 is fixedly connected to the side wall of the work box 1, and a fifth movable roller 18 is rotatably connected to the inner wall of the fourth support frame 19. The movable roller 17 is located at the bottom of the fourth rotating roller 14. When the cylinder 15 pushes the movable frame 16 and drives the movable roller 17 to move upward, the oil film on the movable roller 17 comes into close contact with the bottom of the wallpaper. The fifth movable roller 18 plays the role of auxiliary support and guiding the oil film. The two work together to ensure that the oil film is evenly and flatly adhered to the wallpaper, avoiding adhesion defects such as bubbles and wrinkles, and further optimizing the quality of the wallpaper.

[0027] A heating plate 3 is fixedly connected to the bottom wall of the placement tank 2. The heating plate 3 is optimized for the properties of the adhesive. The fluidity and viscosity of the adhesive are greatly affected by temperature; the adhesive state may be unstable under different ambient temperatures. The heating plate 3 continuously heats the adhesive during operation, ensuring it remains in a suitable working state. This guarantees that the adhesive adheres evenly and smoothly to the wallpaper during the application and coating process by the glue roller 8, enhancing the bonding effect between the wallpaper and the adhesive and avoiding application quality problems caused by poor adhesive state.

[0028] Structural Description: Work Box 1: As the core support body of the entire gluing device, it is made of sturdy and durable materials, such as metal, with sufficient strength and stability. It provides a reliable installation foundation for various internal components, ensuring that the entire gluing process can be carried out in an orderly and stable manner. Its reasonable internal space layout and external structural design facilitate operators to perform operations such as adding glue and threading wallpaper.

[0029] Placement slot 2: Located on the top of work box 1, it is usually a rectangular groove structure with a specially treated inner wall that provides good anti-stick properties, facilitating the holding and cleaning of glue. The size design is based on the approximate amount of glue required for a single application, ensuring sufficient glue supply while avoiding waste due to excessive glue, and allowing operators to easily observe the remaining glue level.

[0030] Heating plate 3: Fixedly installed on the bottom wall inside the placement slot 2, it mainly uses electric heating and integrates a temperature control element and heating wire. The temperature control element accurately senses the glue temperature. When the temperature is lower than the set value, it automatically activates the heating wire to heat the glue, ensuring that the glue is always maintained within a suitable working temperature range, so that the glue maintains good fluidity and viscosity, and ensures the glue application effect.

[0031] First support frame 4: Generally in the form of a column or frame structure, it is vertically fixed to one side of the top of the work box 1. The top end is rotatably connected to the first rotating roller 5 through a bearing, providing stable support for the first rotating roller 5, ensuring that it can rotate flexibly, and guiding the wallpaper smoothly into the starting end of the gluing process. Its height is adapted to the adjacent components to ensure smooth transmission of the wallpaper.

[0032] First rotating roller 5: It is usually a smooth cylindrical roller made of a material with a certain degree of wear resistance, such as rubber or metal material covered with a rubber layer. Its rotating shaft is tightly matched with the bearing at the top of the first support frame 4, and can rotate freely. After one end of the wallpaper is placed on it, the first rotating roller 5 rotates with the traction of the subsequent components, assisting the wallpaper to move forward smoothly.

[0033] The second support frame 6 has an overall structure similar to a frame and is fixed on the top of the work box 1 near the placement slot 2. On the one hand, it provides rotational support for the rubber roller 8 to ensure that the axis of the rubber roller 8 is horizontal and stable; on the other hand, the motor 7 is firmly installed on its side wall, and the output shaft of the motor 7 is precisely connected to the axis of the rubber roller 8 through couplings and other connecting parts to achieve efficient power transmission and drive the rubber roller 8 to rotate and dip in glue.

[0034] Motor 7: Select an industrial motor with appropriate power, based on the required speed, torque and other parameters of the glue roller 8. It has good speed regulation performance and can be precisely adjusted through an external controller to meet the requirements of different wall covering materials and thicknesses on the gluing speed and glue application amount, and stably output power to drive the glue roller 8 to rotate.

[0035] Glue roller 8: It is mostly made of rubber with a certain texture on the surface to enhance the adsorption and coating effect of glue. Its axis passes through the second support frame 6 and is rotatably connected to it. The outer wall of one end is fixedly fitted with the first toothed disc 9, which is linked by meshing with the second toothed disc 10 on the rotating roller 11. During the rotation, the glue in the placement groove 2 is evenly dipped and coated onto the lower surface of the wallpaper.

[0036] First gear 9: A disc-shaped gear made of metal with precise tooth profile. It is coaxially fixedly connected to one end of the rubber roller 8 and rotates synchronously with the rubber roller 8. It meshes tightly with the second gear 10 and transmits the power from the motor 7 to the rubber roller 8 to the rotating roller 11, ensuring that the two work together.

[0037] The second gear 10 is also a metal gear, which is fixedly sleeved on the outer wall of one end of the rotating roller 11. It is compatible with the specifications of the first gear 9 and has high meshing accuracy. It receives the power from the first gear 9 and drives the rotating roller 11 to rotate, thus assisting the glue roller 8 in completing the uniform application of glue.

[0038] Rotating roller 11: Located at the top of the rubber roller 8, it is made of similar material and structure to the rubber roller 8, with a smooth or slightly textured surface. It is rotatably connected to the inner wall of the top of the second support frame 6 through bearings at both ends. Under the meshing transmission of the first toothed disc 9 and the second toothed disc 10, it rotates synchronously with the rubber roller 8, working together with the rubber roller 8 to evenly apply glue to the lower surface of the wallpaper and prevent glue accumulation.

[0039] Fixed box 12: It is mostly a rectangular metal box structure, fixed on the top two sides of the working box 1. The interior is hollow, providing a closed installation space for components such as spring 25, push block 22, and push column 23 in the scraping assembly. Its inner wall is threaded for threaded connection of screw 26, ensuring precise fit of each component and achieving precise control of the position of scraper 21.

[0040] The third support frame 13 is a frame structure that is vertically fixed to the top of the work box 1 on the side away from the second support frame 6. The inner wall of the top is rotatably connected to the fourth rotating roller 14 through a bearing. It is used to receive the wallpaper after the adhesive has been applied, ensuring that the wallpaper is transported smoothly into the subsequent process. Its structural strength can withstand the tension of the wallpaper and ensure the stability of the work.

[0041] The fourth rotating roller 14 is a cylindrical roller with a smooth surface. It fits well with the bearing at the top of the third support frame 13 and rotates freely. It receives the glued wallpaper coming from between the glue roller 8 and the rotating roller 11, provides support for the wallpaper, prevents the wallpaper from sagging or wrinkling, and ensures that the wallpaper can smoothly enter the next processing step.

[0042] Cylinder 15: A standard industrial cylinder with appropriate stroke and thrust is selected and fixedly installed on the top of the work box 1. Its piston rod faces downward and is firmly connected to the top of the movable frame 16. Controlled by an external air source, after receiving a control signal, the piston rod extends and retracts, precisely pushing the movable frame 16 to move up and down, providing power for the adhesion of the oil film and the wallpaper.

[0043] Movable frame 16: Frame structure, driven up and down by the piston rod of cylinder 15, with the inner wall connected to the movable roller 17. The overall structure has good rigidity and stability. Driven by cylinder 15, the movable roller 17 is driven to rise and fit against the bottom of the wallpaper, achieving close contact between the oil film and the wallpaper.

[0044] Movable roller 17: A cylindrical roller with a smooth surface or special treatment according to the requirements of oil film adhesion. The rotating shaft is connected to the bearing on the inner wall of the movable frame 16 and can rotate freely. When the cylinder 15 pushes the movable frame 16 upward, the oil film on the movable roller 17 is tightly adhered to the bottom of the wallpaper, ensuring that the oil film is evenly attached to the wallpaper.

[0045] The fifth movable roller 18 is similar to the movable roller 17. It is fixed to the inner wall of the fourth support frame 19 and located below or to one side of the movable roller 17. It assists in supporting and guiding the oil film and works in conjunction with the movable roller 17 to ensure smooth oil film transmission, avoid oil film wrinkles or deviation, and allow the oil film to adhere smoothly to the wallpaper.

[0046] The fourth support frame 19 is a columnar or frame-like structure fixed to the side wall of the work box 1. It provides stable rotational support for the fifth movable roller 18, ensuring that the axis of the fifth movable roller 18 is horizontal and assisting in the transmission of oil film. Its position and height are coordinated with the movable roller 17 to ensure the smooth progress of the oil film bonding process.

[0047] Limiting frame 20: It is a frame structure composed of metal strips, fixed on the top two sides of the work box 1, and slidably connected to the outer wall of scraper 21. It limits scraper 21 to slide only in a direction perpendicular to the axis of the rubber roller 8, ensuring that the scraper 21 is accurately positioned during adjustment and ensuring accurate control of the glue thickness on the rubber roller 8.

[0048] Scraper 21: Usually made of hard plastic or thin metal sheet, with finely polished blade that fits tightly against the surface of the glue roller 8. One end of it is fixedly connected to the side wall of the push column 23. Driven by the push column 23, it moves closer to or away from the glue roller 8 to precisely scrape off excess glue from the glue roller 8, meeting the glue application needs of different wall coverings.

[0049] Push block 22: It is mostly a block-shaped metal part. One side is rotatably connected to the end of the screw 26, and the other side is adapted to the inclined groove 24 on the push column 23. When the screw 26 rotates, the push block 22 moves under the drive of the screw 26. Through the interaction with the inclined groove 24, it pushes the push column 23 to slide in the fixed box 12, thereby realizing the adjustment of the scraper 21 position.

[0050] Push column 23: A cylindrical metal part that is slidably installed on the inner wall of the fixed box 12. Its side wall is fixedly connected to one end of the scraper 21. It interacts with the push block 22 through the inclined groove 24. With the assistance of the spring 25, it drives the scraper 21 to move, thereby achieving precise control of the glue on the glue roller 8.

[0051] Inclined groove 24: A groove with a certain angle is opened on the surface of the push column 23 and is adapted to the shape of the push block 22. When the push block 22 moves under the drive of the screw 26, the inclined groove 24 guides the push column 23 to slide in the fixed box 12, so as to achieve precise control of the position of the scraper 21.

[0052] Spring 25: A helical spring installed in the internal space of the fixed box 12 between the side wall of the push column 23 and the side wall of the fixed box 12. One end is fixed to the push column 23 and the other end is fixed to the fixed box 12. It plays a role in resetting or buffering. During the adjustment of the scraper 21, it assists the push column 23 in moving and ensures the stability of the scraper 21 position.

[0053] Screw 26: A metal lead screw with threads that match the inner thread of the fixed box 12. One end extends out of the fixed box 12 and has a handle or knob for easy rotation. When the operator rotates the screw 26, it is driven by the thread inside the fixed box 12, which drives the push block 22 to move, thereby adjusting the position of the scraper 21 and achieving precise control of the amount of glue applied.

[0054] The operator places one end of the wallpaper on the first rotating roller 5, then carefully pulls the wallpaper to smoothly pass through the gap between the bottom of the adhesive roller 8 and the rotating roller 11, and finally precisely places it onto the fourth rotating roller 14, completing the wallpaper installation. Simultaneously, suitable adhesive with antibacterial and formaldehyde-removing properties is poured into the placement slot 2 of the work box 1, and the motor 7, fixed to the side wall of the second support frame 6, is started. As the motor 7 operates, the adhesive roller 8, tightly connected to its output end, rotates smoothly on the inner wall of the second support frame 6. Because the first toothed disc 9 fixedly fitted on the outer wall of one end of the adhesive roller 8 precisely meshes with the second toothed disc 10 on the outer wall of one end of the rotating roller 11, the rotation of the adhesive roller 8 cleverly drives the rotating roller 11 to rotate synchronously and in coordination. As the glue roller 8 continues to rotate, it picks up the glue in the placement groove 2 and rotates it evenly to the lower surface of the wallpaper, achieving the initial coating of glue on the wallpaper. The oil film pre-prepared on the fifth movable roller 18 and movable roller 17 comes into play at this time. The cylinder 15 fixedly connected to the top of the working box 1 is started, pushing the movable frame 16 at its output end. The movable frame 16 drives the movable roller 17, which is rotatably connected to the inner wall, to move upward, so that the upper surface of the oil film on the movable roller 17 is tightly attached to the bottom of the wallpaper, completing the glue application and oil film bonding process of the wallpaper, and further optimizing the performance of the wallpaper. When it is necessary to precisely adjust the distance between the scraper 21 and the glue roller 8 according to the wallpaper material and thickness, the operator manually rotates the screw 26. The screw 26 moves outward along the thread on the inner wall of the fixed box 12, gradually leaving the fixed box 12 and extending outward from the fixed box 12. During this process, the screw 26 drives the push block 22, which is rotatably connected to it, to leave the inclined groove 24 on the push column 23. The spring 25, which was originally in a compressed state, instantly resets and releases its elastic force, driving the push column 23 to slide along the inner wall of the fixed box 12 to the outer side of the fixed box 12. The push column 23 then drives the scraper 21, which is fixedly connected to its side wall, to approach the glue roller 8. The scraper 21 can then scrape off the excess glue on the glue roller 8, achieving precise control of the glue coating amount. Conversely, when it is necessary to move the scraper 21 away from the glue roller 8, the screw 26 is rotated in the opposite direction. The screw 26 rotates into the fixed box 12. Under the guidance of the inclined groove 24, the push block 22 pushes the push column 23 to retract into the fixed box 12. The spring 25 is compressed again, and the distance between the scraper 21 and the glue roller 8 increases.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
