Description

Technical Field

[0001] This utility model belongs to the technical field of cleaning equipment for precision coating machines, and specifically relates to a cleaning device applied to the bottom roller of a coating machine. Background Technology

[0002] In the field of precision coating production, the coating roller, as a core component of the coating unit, is directly bonded to the substrate. Its surface smoothness and cleanliness are crucial prerequisites for ensuring product surface quality. During the coating process, adhesive residue can easily remain on the roller surface due to factors such as substrate bonding and pressure, and changes in ambient temperature. If not cleaned thoroughly and promptly, this residue will gradually solidify and accumulate, leading not only to product defects such as uneven coating, missed coatings, and surface scratches in subsequent coating processes, but also potentially damaging the roller's surface coating, shortening its lifespan, and increasing equipment maintenance costs.

[0003] Currently, the industry primarily relies on manual cleaning for coating rollers. This method has several unavoidable drawbacks: First, it poses significant safety risks. Manual cleaning requires the roller to be stopped or running at low speed, and operators must be in close contact with rotating parts, making them highly susceptible to accidents such as mechanical crushing and entanglement. Second, the cleaning effect is poor and unstable. Manual cleaning relies on tools such as scrapers and solvents, making it difficult to completely remove cured residues. Furthermore, the cleaning intensity and scope depend entirely on experience, easily leading to incomplete cleaning or over-cleaning that damages the roller. Third, it is inefficient. Manual cleaning requires frequent shutdowns, severely disrupting the production process, especially in large-scale continuous production scenarios, significantly reducing capacity. Fourth, it carries a high risk of contamination. As precision coating demands higher cleanliness levels in the production environment, Class 100 cleanrooms have become the industry standard. Frequent movement and operation of personnel in the coating area introduces dust, microorganisms, and other contaminants, affecting product cleanliness and failing to meet the production standards for high-precision products.

[0004] In addition, some companies have tried to use simple semi-automatic cleaning devices, but these devices generally have problems such as poor adaptability, limited cleaning range, and uncontrollable cleaning intensity. They cannot flexibly adjust the cleaning position and pressure according to the residual adhesive in different areas of the bottom roller, and it is difficult to achieve coordinated connection between the cleaning process and the production process. Manual intervention is still required, which fails to fundamentally solve the core pain points of manual cleaning. Utility Model Content

[0005] The purpose of this invention is to provide a cleaning device for coating bottom rollers, which solves the problem of low efficiency in cleaning residual adhesive on coating bottom rollers manually in the prior art.

[0006] The technical solution adopted by this utility model is a cleaning device for coating bottom roller, including a pair of supports, a cylinder support shaft and a swing arm support shaft are installed on the inner side walls of the supports, the cylinder support shaft is located below the swing arm support shaft, the cylinder support shaft is connected to a cylinder, the output end of the cylinder is connected to a cylinder swing arm through a cylinder connector, and the cylinder swing arm and the swing arm support shaft are mutually adapted and installed. A rodless cylinder is connected to the end of the cylinder arm away from the cylinder joint. A slider is movably connected to the rodless cylinder, and a cleaning plate is fixed on the slider. A solenoid valve controls the cylinder to rotate the cylinder arm around the support shaft, so that the cleaning plate is pressed against the surface of the bottom roller. The rotation of the bottom roller, in conjunction with the rodless cylinder driving the slider, moves the cleaning plate along the axial direction of the bottom roller, thereby cleaning the surface of the bottom roller.

[0007] The present invention is further characterized in that, The slider is equipped with a lower pressure plate and an upper pressure plate. The lower pressure plate is fixedly connected to the slider, and the upper pressure plate is detachably connected to the lower pressure plate to form a clamping space. The cleaning plate is fixed in the clamping space.

[0008] The tail end of the cylinder is hinged to the cylinder support shaft, and the end of the cylinder connector away from the cylinder is connected to the cylinder rocker arm via a pin.

[0009] A first composite bearing is fixed on the cylinder connector, and a pin passes through the inner side of the first composite bearing.

[0010] The cylinder rocker arm is rotatably connected to the rocker arm support shaft via a second composite bearing.

[0011] The two cylinder rocker arms are connected by a round support.

[0012] The support, cylinder swing arm, upper pressure plate and lower pressure plate are made of Q235-A material and the surface is all nickel plated. The cylinder support shaft, swing arm support shaft, pin shaft, and round support stop are made of 45 steel and all surfaces are nickel-plated.

[0013] The cleaning plate is made of polytetrafluoroethylene, and the cleaning surface of the cleaning plate is adapted to the outer peripheral surface of the coating bottom roller.

[0014] The beneficial effects of this utility model are: (1) This utility model achieves fully automated operation of the cleaning process by controlling the cylinder and rodless cylinder in coordination with the solenoid valve. It eliminates the need for operators to have close contact with the rotating coating roller, thus fundamentally avoiding the safety risks such as mechanical squeezing and entanglement that may be faced during manual cleaning. At the same time, automated operation reduces the flow and intervention of personnel in the coating area, effectively reducing the probability of introducing pollutants such as dust and microorganisms. It is fully compatible with the clean production standards of Class 100 cleanrooms and ensures that the cleanliness of the product is not affected.

[0015] (2) The cleaning plate made of polytetrafluoroethylene (PTFE) in this invention is precisely matched with the outer circumference of the bottom roller, which can closely adhere to the bottom roller surface to scrape off residual adhesive. With the dual action of bottom roller rotation and rodless cylinder driving the cleaning plate to move along the bottom roller axis, the bottom roller surface can be cleaned in all directions without dead angles, solving the problem of residual cured adhesive when cleaning manually. In addition, PTFE has excellent toughness, which avoids damage to the coating on the bottom roller surface during the cleaning process, extends the service life of the bottom roller, and ensures the uniformity of the adhesive layer in the subsequent coating process, significantly improving the stability of product quality.

[0016] (3) The rodless cylinder in this utility model has the function of positioning the slider at any position. It can precisely control the axial movement path and stopping position of the cleaning plate through the solenoid valve. It can achieve comprehensive cleaning of the entire surface of the bottom roller, and can also perform targeted cleaning of key areas where residual glue is concentrated, adapting to the cleaning needs under different coating conditions.

[0019] 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.

[0020] Example 1 This invention relates to a cleaning device for coating bottom rollers, such as... Figure 1 and Figure 2As shown, the device includes a pair of opposing supports 14, which provide a symmetrical and stable mounting foundation for the overall structure, ensuring balanced force and strong stability during operation. Cylinder support shaft 1 and swing arm support shaft 13 are respectively installed on the opposing inner walls of the supports 14, with cylinder support shaft 1 located below swing arm support shaft 13. Cylinder support shaft 1 is adapted to the tail end of cylinder 2, providing reliable fixed support for cylinder 2 and ensuring stability during cylinder 2 operation. The output end of cylinder 2 is connected to cylinder swing arm 11 via cylinder connector 3, ensuring accurate transmission of power from cylinder 2 to cylinder swing arm 11, providing sufficient driving force for swing arm posture adjustment. Cylinder swing arm 11 and swing arm support shaft 13 are mutually adapted, allowing cylinder swing arm 11 to rotate flexibly around swing arm support shaft 13, realizing the engagement / disengagement action of cleaning plate 10 towards or away from the bottom roller.

[0021] The end of the cylinder swing arm 11 away from the cylinder connector 3 is securely connected to the rodless cylinder 7. This installation position allows the rodless cylinder 7 to drive the cleaning component to accurately align with the bottom roller cleaning area, extending the effective range of the cleaning operation. A slider is movably connected to the rodless cylinder 7, and the slider is fixedly connected to the cleaning plate 10. The fixed structure ensures that the cleaning plate 10 does not loosen or shift when it moves with the slider, ensuring the accuracy of the cleaning action.

[0022] During operation, the movement of cylinder 2 is controlled by a solenoid valve, achieving automated control without manual intervention. This improves operational safety and reduces labor costs. Cylinder 2 drives cylinder arm 11 to rotate around arm support shaft 13, causing cleaning plate 10 to press smoothly against the surface of bottom roller. The pressing force is uniform, ensuring that the cleaning plate and bottom roller surface are in close contact, providing a foundation for scraping and cleaning. During the rotation of bottom roller, rodless cylinder 7 synchronously drives slider to move cleaning plate 10 along bottom roller axis, forming a composite cleaning action of "rotation + axial movement". This action can fully cover the bottom roller surface, thoroughly remove residual adhesive, avoid the problem of incomplete manual cleaning, and ensure the quality stability of subsequent coated products.

[0023] Example 2 This invention relates to a cleaning device for coating bottom rollers, such as... Figure 1 and Figure 2 As shown, it includes a pair of supports 14. A cylinder support shaft 1 and a rocker arm support shaft 13 are installed on the inner sidewalls of the supports 14. The cylinder support shaft 1 is located below the rocker arm support shaft 13. The cylinder support shaft 1 is connected to a cylinder 2. The output end of the cylinder 2 is connected to a cylinder rocker arm 11 through a cylinder connector 3. The cylinder rocker arm 11 and the rocker arm support shaft 13 are fitted together. A rodless cylinder 7 is connected to the end of the cylinder arm 11 away from the cylinder connector 3. A slider is movably connected to the rodless cylinder 7, and a cleaning plate 10 is fixed on the slider. The solenoid valve controls the cylinder 2 to rotate the cylinder arm 11 around the arm support shaft 13, so that the cleaning plate 10 is pressed against the surface of the bottom roller. The rotation of the bottom roller, in conjunction with the rodless cylinder 7 driving the slider to move the cleaning plate 10 along the axial direction of the bottom roller, achieves the cleaning of the bottom roller surface.

[0024] Furthermore, the slider is equipped with a lower pressure plate 9 and an upper pressure plate 8. The lower pressure plate 9 and the slider are securely fixed together. This connection design provides a reliable installation foundation for the entire clamping structure, ensuring that the clamping components will not loosen or shift during the cleaning operation, thus laying the foundation for the stable operation of the cleaning plate 10. The upper pressure plate 8 and the lower pressure plate 9 are assembled using a detachable connection method. The core purpose of the detachable structure is to facilitate the installation, replacement, and maintenance of the cleaning plate 10.

[0025] When the cleaning plate 10 wears down due to long-term use or needs to be adapted to different specifications of bottom rollers, the upper pressure plate 8 and the lower pressure plate 9 can be quickly separated for operation without disassembling the entire slider assembly, improving maintenance convenience. After assembly, the two form a closed clamping space, in which the cleaning plate 10 is precisely fixed. The clamping and fixing method ensures that the cleaning plate 10 is subjected to balanced force, preventing the cleaning plate 10 from shifting or tilting due to the rotation of the bottom roller and the force applied to the scraping adhesive during the cleaning process. This ensures a tight fit between the cleaning plate 10 and the surface of the bottom roller, guaranteeing the uniformity and thoroughness of the scraping adhesive cleaning effect.

[0026] Example 3 Based on Embodiment 2 above, in this embodiment, the tail end of the cylinder 2 is hinged to the cylinder support shaft 1. This connection allows the cylinder 2 to rotate flexibly with subsequent actions, adapting to the rotation angle changes of the cylinder swing arm 11, and ensuring no jamming during power transmission. The end of the cylinder connector 3 away from the cylinder 2 is firmly connected to the cylinder swing arm 11 through a pin 4. The pin 4, as the core force transmission component, realizes the accurate transmission of the driving force of the cylinder 2 to the cylinder swing arm 11, ensuring that the two actions are coordinated and consistent.

[0027] Furthermore, a first composite bearing 5 is securely fixed to the cylinder connector 3, and the pin 4 passes through the inner cavity of the first composite bearing 5. The first composite bearing 5 effectively reduces the relative frictional resistance between the pin 4 and the cylinder connector 3, making the pin 4 rotate more smoothly and flexibly under force. This reduces component wear, extends service life, and ensures the responsiveness and transmission stability of the cylinder-driven swing arm.

[0028] Furthermore, the cylinder rocker arm 11 is precisely rotated with the rocker arm support shaft 13 through the second composite bearing 12. The rocker arm support shaft 13 provides stable support for the cylinder rocker arm 11, while the second composite bearing 12 effectively reduces the relative frictional resistance between the two, enabling the cylinder rocker arm 11 to rotate flexibly and smoothly around the rocker arm support shaft 13, avoiding jamming or sticking during the cleaning operation.

[0029] Example 4 This invention relates to a cleaning device for coating bottom rollers, such as... Figure 1 and Figure 2 As shown, it includes a pair of supports 14. A cylinder support shaft 1 and a rocker arm support shaft 13 are installed on the inner sidewalls of the supports 14. The cylinder support shaft 1 is located below the rocker arm support shaft 13. The cylinder support shaft 1 is connected to a cylinder 2. The output end of the cylinder 2 is connected to a cylinder rocker arm 11 through a cylinder connector 3. The cylinder rocker arm 11 and the rocker arm support shaft 13 are fitted together. A rodless cylinder 7 is connected to the end of the cylinder arm 11 away from the cylinder connector 3. A slider is movably connected to the rodless cylinder 7, and a cleaning plate 10 is fixed on the slider. The solenoid valve controls the cylinder 2 to rotate the cylinder arm 11 around the arm support shaft 13, so that the cleaning plate 10 is pressed against the surface of the bottom roller. The rotation of the bottom roller, in conjunction with the rodless cylinder 7 driving the slider to move the cleaning plate 10 along the axial direction of the bottom roller, achieves the cleaning of the bottom roller surface.

[0030] Furthermore, the symmetrically arranged cylinder swing arms 11 on both sides are stably connected laterally by a circular support 6. The circular support 6 extends laterally and is fastened between the cylinder swing arms 11 on both sides. Its core function is to enhance the overall structural rigidity and coordinated linkage of the two sets of cylinder swing arms. This connection design can effectively disperse the lateral force and vibration on the cylinder swing arms during cleaning operations, prevent the single set of swing arms from twisting or deforming due to uneven force, and ensure that the cylinder swing arms 11 on both sides respond synchronously to the drive command of the cylinder 2, and accurately achieve synchronous rotation.

[0031] Meanwhile, the reinforcement effect of the circular support 6 makes the installation base of the cleaning component more stable, preventing the cleaning plate from shifting due to the swing arm during the glue scraping process, ensuring the uniformity of the cleaning plate and the bottom roller surface, and thus improving the stability and reliability of the cleaning effect.

[0032] Example 5 Based on Embodiment 4 above, in this embodiment, the support 14, cylinder swing arm 11, upper pressure plate 8, and lower pressure plate 9 are all made of Q235-A material. This material has excellent toughness and structural adaptability, which can meet the basic requirements of the device for component rigidity in core functions such as support and clamping. At the same time, the surfaces of these parts are all nickel-plated, which effectively improves their corrosion resistance and wear resistance, and can avoid component wear caused by environmental factors or friction during long-term use, thus ensuring structural stability and service life.

[0033] The cylinder support shaft 1, swing arm support shaft 13, pin shaft 4, and circular support stop 6 are all made of 45 steel. 45 steel has higher strength and load-bearing capacity, which can meet the usage requirements of key force transmission and support scenarios, ensuring accurate power transmission and reliable structural reinforcement. In addition, the surfaces of these parts are also nickel-plated, which further enhances their ability to resist corrosion and reduce wear, reduces frictional loss when parts are in contact, extends the overall service life of the device, and ensures stability and reliability during long-term operation.

[0034] Example 6 Based on Embodiment 5 above, the cleaning plate 10 in this invention is specifically made of polytetrafluoroethylene (PTFE). This material possesses excellent non-stick properties, wear resistance, and flexibility. It effectively prevents the reduction in cleaning efficiency caused by adhesive adhering to the surface of the cleaning plate 10 during the cleaning process, and also allows for flexible contact with the bottom roller during adhesive scraping, fundamentally eliminating damage to the coating layer on the coating bottom roller surface. Simultaneously, the cleaning surface of the cleaning plate 10 is precisely designed to fit perfectly against the outer circumference of the coating bottom roller, ensuring complete coverage of the roller surface during cleaning, leaving no cleaning dead corners, thoroughly scraping away residual adhesive, and guaranteeing the cleanliness and flatness of the roller surface. This lays a solid foundation for the quality stability of subsequent coating processes.
