Description
Technical Field
[0001] This application relates to the field of film head cleaning technology for release paper laminating machines, specifically an automatic cleaning device for the film head of a release paper laminating machine. Background Technology
[0002] A coating machine, also known as an extrusion laminating machine, extrusion casting machine, or casting laminating machine, is a type of extrusion molding machinery. It has advantages such as high automation, simple operation, high production speed, uniform coating thickness, and high adhesion strength. It is mainly used to replace dry lamination and hot melt adhesive coating lamination. When the coating machine is running, plastic particles are plasticized by the screw and then extruded in a linear shape through the die head. After stretching, they are attached to the surface of flexible substrates such as paper or film. After cooling, shaping, and pressing, they are combined into a composite material that has the barrier and heat-sealing properties of the plastic film layer, as well as the strength and functional properties of the substrate.
[0003] During the production process of existing release paper laminating machines, residues continuously accumulate on the surface of the film head. If not cleaned in time, this will lead to a decline in product quality and a reduction in production efficiency. Currently, the industry generally relies on manual cleaning of residues on the surface of the film head. Manual operation is limited by human strength and operating speed, and cleaning one film head takes a lot of time, resulting in low efficiency and affecting the overall production progress. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides an automatic cleaning device for the film head of a release paper laminating machine. This device has advantages such as automatic cleaning and solves the problem that in existing release paper laminating machines, residues continuously accumulate on the surface of the film head during production. If not cleaned in time, this can lead to a decline in product quality and a reduction in production efficiency. Currently, the industry generally relies on manual cleaning of residues on the surface of the film head. Manual operation is limited by human strength and operating speed, and cleaning one film head takes a lot of time, resulting in low efficiency and affecting the overall production progress.
[0005] To achieve the above objectives, this application provides the following technical solution: an automatic cleaning device for the film head of a release paper coating machine, comprising two mounting flanges and two rotating seats. Support plates are fixedly connected to the outer walls of both mounting flanges. A sliding groove is formed on one side of each of the two support plates. First fixed seats are fixedly connected to the upper and lower ends of both support plates. Electric push rods are fixedly connected to one side of each of the four first fixed seats. A cleaning roller is rotatably connected between the two rotating seats. Second fixed seats are fixedly connected to the upper and lower ends of both rotating seats. A sliding plate is fixedly connected to one side of each rotating seat. A support seat is fixedly connected to the upper end of each rotating seat. A water distribution pipe is fixedly connected between the two support seats. Multiple nozzles arranged in a linear array are fixedly connected to the outer wall of the water distribution pipe.
[0006] The above solution utilizes an electric push rod to drive the cleaning roller, which, combined with its rotation, achieves automatic cleaning without manual intervention. This improves cleaning efficiency, reduces the time and effort required for manual operation, and lowers labor costs. The two mounting flanges and support plates allow for quick docking and installation with the coating machine. The symmetrically distributed support plates form a stable frame structure, providing solid support for the entire device. The chute and slide plate work together to reliably ensure the linear movement of the cleaning roller. This design allows the cleaning roller to maintain a stable trajectory during movement, ensuring the accuracy and effectiveness of cleaning. The electric push rod can flexibly adjust the contact pressure between the cleaning roller and the membrane head to adapt to different cleaning needs. By adjusting the contact pressure, appropriate cleaning of the membrane head can be achieved, removing surface stains and impurities without damaging the membrane head. The water distribution pipe and multiple nozzles ensure that the cleaning solution is evenly sprayed onto the surface of the cleaning roller. As the cleaning roller rotates, it ensures that the cleaning solution fully covers the membrane head, improving the cleaning effect and efficiency.
[0007] Furthermore, a motor is fixedly connected to one side of the rotating seat, and the output end of the motor passes through one side of the rotating seat and is fixedly connected to the cleaning roller via a coupling.
[0008] With the above solution, the output end of the motor is fixedly connected to the cleaning roller through a coupling, ensuring the stability of power transmission and enabling the cleaning roller to obtain stable rotational power.
[0009] Furthermore, a water tank is fixedly connected to one side of the support plate, and a connecting pipe is fixedly connected to the bottom of the water tank; a pump is fixedly connected to one side of the rotating seat, and an inlet pipe is fixedly connected to the output end of the pump.
[0010] With the above solution, the water tank is fixed to one side of the support plate, providing an independent storage space for the cleaning fluid. The capacity of the water tank can be designed according to actual needs to meet the cleaning work requirements for a certain period of time. During the cleaning process, the extraction pump can continuously extract cleaning fluid from the water tank to ensure that the cleaning roller and nozzle always have a sufficient supply of cleaning fluid, thus improving the continuity and stability of cleaning.
[0011] Furthermore, the end of the connecting pipe furthest from the water tank is fixedly connected to the input end of the pump, and the end of the inlet pipe furthest from the pump is fixedly connected to the distribution pipe.
[0012] With the above solution, the pump draws cleaning fluid directly from the water tank through the connecting pipe, ensuring that the cleaning fluid is delivered to the distribution pipe at a stable pressure and flow rate, so that the pressure of the cleaning fluid in the distribution pipe is uniform and the spraying effect of multiple nozzles is consistent.
[0013] Furthermore, an infrared transmitter and an infrared receiver are fixedly connected to one side of each of the two support plates, and the infrared transmitter and infrared receiver correspond to each other.
[0014] With the above scheme, the infrared transmitter and infrared receiver are set up in pairs. When the membrane head surface is clean, the infrared light can be transmitted in a straight line and successfully received by the infrared receiver. Once dirt accumulates on the membrane head surface, the dirt will block the transmission of infrared light, causing the infrared receiver signal to be interrupted. When the infrared receiver detects the signal interruption, the system can automatically start the cleaning device without manual intervention.
[0015] Furthermore, both of the aforementioned slide plates are slidably disposed inside the slide groove.
[0016] With the above solution, the slide plate slides along the groove, ensuring that the cleaning components move along the set trajectory.
[0017] Furthermore, the telescopic ends of the four electric push rods are fixedly connected to the second fixed base.
[0018] With the above scheme, the four electric push rods are arranged in a rectangular shape and connected to the second fixed seat through the telescopic end to form a stable support structure. The multi-point support can effectively disperse the pressure during membrane head cleaning, avoid tilting or shaking caused by single-point force, and improve the stability of the equipment. The electric push rods can also adjust the pressure of the cleaning roller contacting the membrane head by telescopic adjustment.
[0019] Furthermore, a sealing cap is threaded onto the upper end of the water tank.
[0020] With the above solution, the sealing cap is connected to the water tank by threads. Rotating the sealing cap can seal or open the tank. When the cleaning fluid is used up, the sealing cap can be quickly unscrewed to replenish it.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects: This automatic cleaning device for the film head of a release paper coating machine uses an electric push rod to drive the cleaning roller. Combined with the rotation of the cleaning roller, it achieves automatic cleaning without manual intervention, improving cleaning efficiency, reducing the time and effort required for manual operation, and lowering labor costs. The two mounting flanges and support plates allow for quick docking and installation with the coating machine. The symmetrically distributed support plates form a stable frame structure, providing solid support for the entire device. The sliding groove and slide plate work together to reliably ensure the linear movement of the cleaning roller. This design allows the cleaning roller to maintain a stable trajectory during movement, ensuring the accuracy and effectiveness of cleaning. The electric push rod can flexibly adjust the contact pressure between the cleaning roller and the film head to adapt to different cleaning needs. By adjusting the contact pressure, moderate cleaning of the film head can be achieved, removing surface stains and impurities without damaging the film head. The water distribution pipe and multiple nozzles ensure that the cleaning solution is evenly sprayed onto the surface of the cleaning roller. As the cleaning roller rotates, it ensures that the cleaning solution fully covers the film head, improving the cleaning effect and efficiency. Attached Figure Description

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0025] Please see Figure 1 , Figure 2 and Figure 3 This embodiment of an automatic cleaning device for the film head of a release paper coating machine includes two mounting flanges 1 and two rotating seats 6. Support plates 2 are fixedly connected to the outer walls of both mounting flanges 1. The arrangement of the mounting flanges 1 and support plates 2 allows for quick docking and installation of the automatic cleaning device with the coating machine. The symmetrically distributed support plates 2 form a stable frame structure, providing solid support for the entire device. A sliding groove 3 is provided on one side of each of the two support plates 2. First fixed seats 4 are fixedly connected to the upper and lower ends of each of the two support plates 2. Electric push rods 5 are fixedly connected to one side of each of the four first fixed seats 4. The electric push rods 5 can flexibly adjust the contact pressure to adapt to different cleaning needs. A cleaning roller 7 is rotatably connected between the two rotating seats 6. The cleaning roller 7 is electrically connected to the roller. The push rod 5 drives the cleaning roller 7 to move. Combined with the rotation of the cleaning roller 7, automatic cleaning without manual intervention is achieved, which improves cleaning efficiency, reduces the time and effort invested in manual operation, and lowers labor costs. The upper and lower ends of the two rotating seats 6 are fixedly connected to the second fixed seats 8, and the side of the two rotating seats 6 is fixedly connected to the slide plate 9. The upper end of the two rotating seats 6 is fixedly connected to the support seat 10, and the two support seats 10 are fixedly connected to the water distribution pipe 11. Multiple nozzles 12 arranged in a linear array are fixedly connected to the outer wall of the water distribution pipe 11. The arrangement of the water distribution pipe 11 and multiple nozzles 12 allows the cleaning liquid to be sprayed evenly on the surface of the cleaning roller 7. As the cleaning roller 7 rotates, it ensures that the cleaning liquid fully covers the film head, which improves the cleaning effect and efficiency.
[0026] Please see Figure 1 , Figure 3 and Figure 4A motor 13 is fixedly connected to one side of a rotating base 6. The output end of the motor 13 passes through one side of the rotating base 6 and is fixedly connected to the cleaning roller 7 via a coupling. This connection ensures the stability of power transmission, allowing the cleaning roller 7 to obtain stable rotational power. A water tank 14 is fixedly connected to one side of a support plate 2. A connecting pipe 16 is fixedly connected to the bottom of the water tank 14. A pump 17 is fixedly connected to one side of another rotating base 6. An inlet pipe 18 is fixedly connected to the output end of the pump 17. The water tank 14, fixed to one side of the support plate 2, provides an independent storage space for the cleaning solution. The capacity of the water tank 14 can be adjusted according to actual needs. The design is capable of meeting the cleaning needs within a certain time period. During the cleaning process, the extraction pump 17 can continuously extract cleaning fluid from the water tank 14, ensuring that the cleaning roller 7 and the nozzle 12 always have a sufficient supply of cleaning fluid, thus improving the continuity and stability of cleaning. The end of the connecting pipe 16 away from the water tank 14 is fixedly connected to the input end of the extraction pump 17, and the end of the water inlet pipe 18 away from the extraction pump 17 is fixedly connected to the water distribution pipe 11. The extraction pump 17 directly draws cleaning fluid from the water tank 14 through the connecting pipe 16, ensuring that the cleaning fluid is delivered to the water distribution pipe 11 at a stable pressure and flow rate, so that the pressure of the cleaning fluid in the water distribution pipe 11 is uniform, ensuring that the spraying effect of multiple nozzles 12 is consistent.
[0027] Please see Figure 1 , Figure 4 and Figure 5 Infrared transmitters 19 and infrared receivers 20 are fixedly connected to one side of each of the two support plates 2. The infrared transmitters 19 and infrared receivers 20 correspond to each other and are set up in pairs. When the surface of the membrane head is clean, the infrared light can be transmitted in a straight line and successfully received by the infrared receivers 20. Once dirt accumulates on the membrane head surface, it will block the transmission of infrared rays, causing the infrared receiver 20 to lose signal. When the infrared receiver 20 detects the signal interruption, the system can automatically start the cleaning device without manual intervention. Both slide plates 9 are slidably set inside the slide groove 3. The slide plates 9 slide through the slide groove 3 to ensure that the cleaning components move along the set trajectory. The telescopic ends of the four electric push rods 5 are fixedly connected to the second fixed base 8. The four electric push rods 5 are arranged in a rectangle and are connected to the second fixed base 8 through their telescopic ends to form a stable support structure. Multi-point support can effectively disperse the pressure during membrane head cleaning, avoid tilting or shaking caused by single-point force, and improve the stability of the equipment. The setting of the electric push rods 5 can also adjust the pressure of the cleaning roller 7 contacting the membrane head by telescopic adjustment. The upper end of the water tank 14 is threaded with a sealing cap 15. The sealing cap 15 is connected to the water tank 14 through the thread. Rotating the sealing cap 15 can seal or open the tank. When the cleaning fluid is used up, the sealing cap 15 can be quickly unscrewed to replenish the fluid.
[0028] In this embodiment, the automatic cleaning device for the film head of a release paper coating machine drives the cleaning roller 7 to move via an electric push rod 5. Combined with the rotation of the cleaning roller 7, automatic cleaning without manual intervention is achieved, improving cleaning efficiency, reducing the time and effort required for manual operation, and lowering labor costs. The two mounting flanges 1 and the support plate 2 enable the automatic cleaning device to be quickly connected and installed with the coating machine. The symmetrically distributed support plates 2 form a stable frame structure, providing solid support for the entire device. The sliding groove 3 and the sliding plate 9 cooperate to provide reliable assurance for the linear movement of the cleaning roller 7. This design allows the cleaning roller 7 to maintain a stable movement trajectory during movement, ensuring the accuracy and effectiveness of cleaning. The electric push rod 5 can flexibly adjust the contact pressure between the cleaning roller 7 and the film head to adapt to different cleaning needs. By adjusting the contact pressure, the membrane head can be properly cleaned, removing surface stains and impurities without damaging it. The water distribution pipe 11 and multiple nozzles 12 ensure that the cleaning solution is evenly sprayed onto the surface of the cleaning roller 7. As the cleaning roller 7 rotates, it ensures that the cleaning solution fully covers the membrane head, improving the cleaning effect and efficiency.
[0029] It should be noted that when the device is in standby mode after installation, all four electric push rods 5 are extended. At this time, the cleaning roller 7 is away from the film head of the coating machine, so that the coating machine can operate normally and prevent the cleaning device from interfering with it.
[0030] The working principle of the above embodiments is as follows: First, the device is installed on one side of the membrane head of the coating machine via two mounting flanges 1. Two symmetrically distributed support plates 2 form a stable frame. Sliding grooves 3 are cut inside the support plates 2. Four electric push rods 5 are fixed at the upper and lower ends via first fixing seats 4, providing rigid support for the cleaning device. The cleaning roller 7 is initially positioned outside the membrane head cleaning area in a standby state. The rotating sealing cover 15 injects cleaning fluid into the water tank 14. Then, the sealing cover 15 is rotated to close. The infrared emitter 19 continuously emits an infrared beam, and the infrared receiver 20 receives the signal in real time. When the membrane head surface is clean, the infrared light transmits in a straight line without obstruction, and the infrared receiver 20 receives the signal stably. If stains appear on the membrane head surface to a certain extent, the stains block the infrared light transmission. The infrared receiver 20 experiences a signal interruption. Upon receiving the signal interruption signal, the controller controls the extraction pump 17 to extract cleaning fluid from the water tank 14 via the connecting pipe 16. The fluid is then transported to the distribution pipe 11 via the inlet pipe 18. The cleaning fluid is evenly sprayed onto the surface of the cleaning roller 7 from multiple nozzles 12. The four electric push rods 5 retract synchronously, causing the rotating seat 6 to slide along the slide groove 3, making the cleaning roller 7 adhere to the surface of the membrane head. The motor 13 drives the cleaning roller 7 to rotate via the coupling. Combined with the cleaning fluid sprayed from the nozzles 12, the surface of the membrane head is cleaned. After cleaning, the four electric push rods 5 extend synchronously, the cleaning roller 7 returns to its initial position, the cleaning fluid supply is interrupted, the nozzles 12 stop spraying, and the cleaning device enters standby mode, waiting for the next stain detection.
