Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a membrane coating mechanism that, before applying adhesive, uniformly blows and cleans the membrane to prevent particulate matter from adhering to the membrane surface and ensures the cleanliness of the membrane surface.

[0004] To solve the above technical problems, the technical solution adopted by this utility model is: a film coating mechanism, including: a frame body, a transmission box located on the frame body, an applicator roller and a coating roller, wherein at least two sets of conveyor rollers are arranged at intervals in the transmission box, and the applicator roller and the coating roller are located on the side of the two sets of conveyor rollers away from the inlet of the transmission box and above the frame body. The bottom of the transmission box is equipped with a connected box body and a fan. A dust suction head located between two sets of conveyor wheels is connected to the box body through a connecting pipe. A distribution plate located between the conveyor wheels and the dust suction head is connected to the fan through a diversion pipe. The fan is connected to the box body. The upper surface of the distribution plate, which has a cavity, has several through holes communicating with the cavity. The diversion pipe is connected to the cavity of the distribution plate. A filter plate is installed inside the box body.

[0005] The following are further improvements to the above technical solution: 1. In the above scheme, one set of conveyor wheels is close to the inlet of the transmission box, and the other set of conveyor wheels is located in the middle of the transmission box.

[0006] 2. In the above solution, the vacuum head and the distribution plate are located at the bottom of the box.

[0007] 3. In the above scheme, the through hole is inclined toward the inlet of the transmission box, and the suction head is oriented toward one side of the through hole.

[0008] 4. In the above solution, a support rod that can contact the membrane material is installed above the vacuum head.

[0009] 5. In the above solution, the vacuum head is located directly below the support rod.

[0010] 6. In the above scheme, the plurality of through holes are equally spaced on the distribution plate.

[0011] 7. In the above scheme, the filter plate is located on the side of the housing closer to the fan.

[0012] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art: 1. The membrane coating mechanism of this utility model has a box body and a fan installed at the bottom of the transmission box. A dust suction head located between two sets of conveyor wheels is connected to the box body through a connecting pipe. A distribution plate located between the conveyor wheels and the dust suction head is connected to the fan through a diversion pipe. The upper surface of the distribution plate with a cavity has several through holes communicating with the cavity. The diversion pipe is connected to the cavity of the distribution plate. A filter plate is installed inside the box. Before coating, the membrane material is uniformly blown and cleaned to avoid the adhesion of particulate matter on the surface of the membrane material and ensure the cleanliness of the membrane material surface.

[0013] 2. The film coating mechanism of this utility model has through holes on the upper surface of the distribution plate that communicate with the cavity, blowing air towards the substrate. The through holes face the inlet of the transfer box, while the suction head faces one side of the through holes. The air blown from the through holes towards the substrate blows the particles on the substrate towards the suction head, which then sucks them into the box. The suction head and the airflow from the through holes can work together to increase the airflow force, allowing the suction head to promptly suck the particles blown off the substrate into the box, thus increasing the cleaning power of the particles on the substrate surface and further improving the cleanliness of the substrate. Furthermore, the suction head promptly sucks the particles blown off the substrate into the box, preventing the particles from re-adhering to the clean substrate. Additionally, a support rod that can contact the film is installed above the suction head. This support rod supports the substrate during cleaning, preventing excessive airflow from causing the substrate to come into close contact with the suction head and causing scratches and wear, thus ensuring the quality of the substrate after coating and reducing resource waste.

[0016] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.

[0017] Example 1: A film coating mechanism includes: a frame body 1, a transfer box 2 located on the frame body 1, an application roller 8 and a coating roller 9. At least two sets of conveyor rollers 21 are arranged at intervals in the transfer box 2. The application roller and the coating roller are located on the side of the two sets of conveyor rollers 21 away from the inlet of the transfer box 2 and above the frame body 1. The bottom of the transmission box 2 is equipped with a connected box body 3 and a fan 4. A dust suction head 5 located between two sets of conveyor wheels 21 is connected to the box body 3 through a connecting pipe 6. A distribution plate 10 located between the conveyor wheels 21 and the dust suction head 5 is connected to the fan 4 through a diversion pipe 11. The fan 4 is connected to the box body 3. The upper surface of the distribution plate 10, which has a cavity 101, has several through holes 12 that communicate with the cavity 101. The diversion pipe 11 communicates with the cavity 101 of the distribution plate 10. A filter plate 13 is installed inside the box body 3.

[0018] The aforementioned vacuum head 5 and distribution plate 10 are located at the bottom of the housing 3.

[0019] The aforementioned through hole 12 is tilted towards the inlet of the transmission box 2, and the suction head 5 is oriented to the same side as the through hole 12. This allows the suction head and the airflow of the through hole to work together to increase the airflow, and the suction head to promptly suck the particles blown off the substrate into the box, thereby increasing the cleaning power of the particles on the substrate surface and further improving the cleanliness of the substrate. At the same time, the suction head can promptly suck the particles blown off the substrate into the box, preventing the particles from re-adhering to the clean substrate.

[0020] The aforementioned through holes 12 are evenly spaced on the distribution plate 10.

[0021] The filter plate 13 mentioned above is located on the side of the housing 3 near the fan 4.

[0022] Example 2: A film coating mechanism, comprising: a frame body 1, a transfer box 2 located on the frame body 1, an application roller 8 and a coating roller 9, wherein at least two sets of conveying wheels 21 are spaced apart in the transfer box 2, and the application roller and the coating roller are located on the side of the two sets of conveying wheels 21 away from the inlet of the transfer box 2 and above the frame body 1. The bottom of the transmission box 2 is equipped with a connected box body 3 and a fan 4. A dust suction head 5 located between two sets of conveyor wheels 21 is connected to the box body 3 through a connecting pipe 6. A distribution plate 10 located between the conveyor wheels 21 and the dust suction head 5 is connected to the fan 4 through a diversion pipe 11. The fan 4 is connected to the box body 3. The upper surface of the distribution plate 10, which has a cavity 101, has several through holes 12 that communicate with the cavity 101. The diversion pipe 11 communicates with the cavity 101 of the distribution plate 10. A filter plate 13 is installed inside the box body 3.

[0023] Of the two sets of conveyor wheels 21, one set is located near the inlet of the transmission box 2, while the other set is located in the middle of the transmission box 2.

[0024] The aforementioned vacuum head 5 and distribution plate 10 are located at the bottom of the housing 3.

[0025] A support rod 7 that can contact the film material 14 is installed above the aforementioned vacuum head 5. The support rod can support the substrate when cleaning the substrate, preventing excessive wind force from causing the substrate to get too close to the vacuum head and causing scratches and wear on the substrate, thus ensuring the quality of the substrate after coating and reducing resource waste.

[0026] The aforementioned vacuum head 5 is located directly below the support rod 7.

[0027] The aforementioned through holes 12 are evenly spaced on the distribution plate 10.

[0028] The filter plate 13 mentioned above is located on the side of the housing 3 near the fan 4.

[0029] The working principle is as follows: The substrate enters the transfer box 2 through the conveyor wheel 21 near the inlet of the transfer box 2. The fan 4 starts to operate and begins to clean the substrate: the fan 4 sucks the particles on the substrate into the box 3 through the dust suction head 5. The filter plate 13 installed in the box 3 blocks the particles in the box 3. The air enters the fan 4 through the filter plate 13, and then enters the cavity 101 of the distribution plate 10 through the diversion pipe 11. Finally, the air is blown onto the substrate through the through hole 121 on the upper surface of the distribution plate 10 that communicates with the cavity 101. The through hole 12 faces the inlet of the transfer box 2, while the suction head 5 faces the opposite direction to the through hole 12. The air blown from the through hole 12 toward the substrate blows the particles on the substrate toward the suction head 5, which then sucks them into the box 3. This prevents particles from remaining attached to parts of the substrate when the wind force is weak, thus reducing the cleaning quality. This improves the blowing force on specific areas of the substrate and further improves the cleaning effect. There is a gap between the support rod 7 and the suction head 5 to prevent the substrate from sticking tightly to the suction head 5 due to the wind force, which could cause scratches and wear on the substrate. After cleaning, the substrate is coated with glue by the gluing roller 8 and the coating roller 9. After the glue is applied, the substrate is transported out of the transfer box 2 for drying, cutting, or winding.

[0030] When the above-mentioned film coating mechanism is used, the particulate matter on the substrate is sucked into the box by blowing air with a fan, which not only ensures the cleanliness of the substrate surface, but also improves the automation of the entire coating process. In addition, the through holes on the upper surface of the distribution plate, which communicate with the cavity, blow air towards the substrate. The through holes face the inlet of the transfer box, while the suction head faces one side of the through holes. The air blown from the through holes towards the substrate blows the particles on the substrate towards the suction head, which then sucks them into the box. The suction head and the airflow from the through holes can work together to increase the airflow force, allowing the suction head to promptly suck the particles blown off the substrate into the box. This increases the cleaning power of the particles on the substrate surface and improves the cleanliness of the substrate. Furthermore, the suction head can promptly suck the particles blown off the substrate into the box, preventing the particles from re-adhering to the clean substrate. Moreover, a support rod that can contact the film is installed above the suction head. This support rod can support the substrate during cleaning, preventing the substrate from getting too close to the suction head due to excessive airflow, which could cause scratches and abrasions. This ensures the quality of the substrate after coating and reduces resource waste.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
