[0006] The aforementioned components achieve the following effect: When using a laminating machine to process the bottom of a household appliance foam board, before the previous processing equipment finishes producing the foam board and before it is conveyed to the first conveyor belt, a cleaning device cleans the bottom of the foam board to remove foam debris and dust from the area to be laminated, preventing any impact on the adhesion of the subsequent lamination. During lamination, a laminating roll with adhesive is first installed on a placement roller, and then the household appliance foam board is placed on one of the first conveyor belts. Through the control box, one of the first motors is started, driving one of the first shafts to rotate, which in turn drives the first conveyor belt to transport the foam board. When the board is transported between two first conveyor belts, the adhesive film on the placement roller adheres to the bottom of the foam board, and simultaneously... The second motor is started to drive the placement roller to unwind the coated roll. Then, the appliance foam board is conveyed to another first conveyor belt, and at the same time, the second first conveyor belt is started to drive the first round shaft to rotate, which in turn drives the second first conveyor belt to continue conveying the coated appliance foam board to the cutting knife. Then, the first electric telescopic rod drives the cutting knife to cut the film. The cut coated appliance foam board is then conveyed to the second conveyor belt. At this time, the third motor on the coating machine frame drives the second round shaft to rotate, which moves the second conveyor belt to convey the coated appliance foam board to the push rod. Then, the second electric telescopic rod is started, which pushes the film extending from both sides of the appliance foam board upward, so that the film finally adheres to both sides of the appliance foam board. Then, the second conveyor belt conveys the coated foam board out of the coating machine frame, completing the coating process.

A cleaning device 2 is provided on one side of the laminating frame 1. The cleaning device 2 can drive a cleaning brush 22 via a fourth motor 23 to clean the bottom of the appliance foam board that has not yet been laminated. At the same time, it works with a collection mechanism 26 to collect the foam debris and dust impurities that are cleaned off, so as to achieve a cleaner surface for the appliance foam board.When using a laminating machine to laminate the bottom of appliance foam boards, before the foam boards are conveyed to the first conveyor belt 5 after production by the previous processing equipment, the bottom of the foam boards is cleaned by a cleaning device 2. This cleans away foam debris and dust from the surface of the area to be laminated, preventing any impact on the adhesion of the subsequent lamination. During lamination, a laminating roll with adhesive is first installed on a placement roller 7, and then the appliance foam board is placed on one of the first conveyor belts 5. The control box 3 operates by starting one of the first motors 6, which drives one of the first shafts 4 to rotate, thus conveying the appliance foam board onto the first conveyor belt 5.

Then, the second electric telescopic rod 15 is started, which pushes the film extending from both sides of the appliance foam board upward, so that the film finally adheres to both sides of the appliance foam board. Then, the second conveyor belt 12 conveys the foam board with the film out of the laminating frame 1, thus completing the laminating process.

A cleaning brush 22 is provided, with both ends of the cleaning brush 22 respectively installed through the inner wall of the first bracket 21 on both sides. A fourth motor 23 is provided, with one side of the fourth motor 23 fixedly installed on one side of the first bracket 21 and the output end fixedly installed on one side of one end of the cleaning brush 22 by means of a coupling. By setting up the cleaning device 2, when the appliance foam board is processed from the previous production equipment and conveyed to the first transmission belt, the cleaning brush 22 and the first support 21 will adhere tightly to the bottom of the appliance foam board under the action of the adjusting mechanism 25. At this time, the fourth motor 23 can be started by the control box 3 to drive the cleaning brush 22 to rotate on the first support 21. The rotation direction is opposite to the movement direction of the appliance foam board, cleaning off the foam debris and dust impurities attached to its bottom. Then, the collection mechanism 26 will adsorb and collect them to prevent them from falling back onto the appliance foam board. This will not affect the subsequent lamination process, improve the adhesion and flatness between the lamination and the appliance foam board, and improve the efficiency of the lamination process.

[0033] Figure 1-6 The cleaning device 2 shown also includes a scraper 27, with both sides of the scraper 27 fixedly installed on the inner wall of one end of the first bracket 21. The scraper 27 is located at the end of the first bracket 21 away from the first conveyor belt 5. By setting the scraper 27, when the appliance foam board is conveyed to the first conveyor belt 5, the bottom will first contact one end of the scraper 27, and the scraper 27 will perform preliminary scraping and cleaning of the bottom, removing the attached foam debris and dust impurities, which facilitates subsequent cleaning.

[0034] Figure 1-6The collection mechanism 26 shown includes a collection cover 261, wherein the inner walls of the collection cover 261 are fixedly connected to both ends of a rectangular rod 24; two second supports 266, wherein the two ends of the second supports 266 are fixedly installed on one side of the collection cover 261 and one side of the film-coating frame 1; a blower 263, wherein the two sides of the blower 263 are fixedly installed on one side of the two second supports 266; a conveying pipe 262, wherein the two ends of the conveying pipe 262 are fixedly installed at the inlet of the blower 263 and the outlet of the collection cover 261; and a cloth bag 264, wherein one end of the cloth bag 264 is spirally sleeved on the outer surface of the outlet of the blower 263. By setting up the collection mechanism 26, after the cleaning brush 22 and scraper 27 brush off the foam debris and dust from the bottom of the appliance foam board, the fan 263 can be activated to suck the cleaned debris and dust into the delivery pipe 262 through the dust suction hood, and then collect it inside the cloth bag 264 to prevent it from adhering to the appliance foam board again, thus improving the cleaning effect and facilitating subsequent unified disposal. Reinforcing rods 265 are fixedly installed on both sides of one end of the second support 266, with one side of the reinforcing rod 265 fixedly installed on one side of the laminating machine frame 1.

[0035] Figure 1-6 The adjustment mechanism 25 shown includes several springs 252, with both ends of the springs 252 fixedly mounted on one side of the rectangular rod 24 and one side of the first bracket 21, respectively. The inner wall of the collection cover 261 has grooves 251 on both sides, and both ends of the first bracket 21 are slidably mounted in the inner wall of the grooves 251. By setting the adjustment mechanism 25, when the appliance foam board is conveyed from the previous processing equipment and pressed onto the cleaning brush 22, it presses and pushes the cleaning brush 22 downwards, causing the first bracket 21 to slide in the grooves 251, compressing the springs 252 to a certain height. Simultaneously, the springs 252 return the first bracket 21 to its original position, ensuring the surface of the cleaning brush 22 is tightly against the bottom of the appliance foam board for easy cleaning later. The adjustment mechanism 25 also includes several support rods 253, with one end of each support rod 253 fixedly mounted on one side of the first bracket 21, and the other end penetrating through the inner wall of the spring 252 and connecting to one side of the rectangular rod 24. By setting the support rod 253, the inner wall of the spring 252 can be supported and reinforced, making it less prone to damage during use and extending its service life.

[0036] Working principle: When using the laminating machine to process the bottom of the appliance foam board, as the appliance foam board is conveyed from the previous processing equipment and pressed onto the cleaning brush 22 and scraper 27, the cleaning brush 22 and scraper 27 are pressed and pushed downwards, causing the first support 21 to slide in the slide groove 251, compressing its spring 252 to a certain height. At the same time, the spring 252 will reset the first support 21, keeping the surface of the cleaning brush 22 tightly against the bottom of the appliance foam board. As the appliance foam board is conveyed, the scraper 27 will perform preliminary scraping and cleaning of its bottom. Simultaneously, the control box 3 controls the start of the fourth motor 23 to drive... The cleaning brush 22 rotates on the first support 21 in the opposite direction to the movement of the appliance foam board, cleaning off the foam debris and dust adhering to its bottom. Simultaneously, the fan 263 draws the cleaned debris and dust into the delivery pipe 262 via a dust suction hood, where it is collected inside the cloth bag 264 to prevent re-adhesion onto the appliance foam board. This avoids affecting subsequent lamination processing, improves the adhesion and flatness between the laminator and the appliance foam board, and increases lamination efficiency. During lamination, a lamination roll with adhesive is first installed on the placement roller 7, and then the appliance foam board is placed... On one of the first conveyor belts 5, the control box 3 operates by starting one of the first motors 6, which drives one of the first round shafts 4 to rotate. This causes the first conveyor belt 5 to transport the appliance foam board. When the foam board is transported between the two first conveyor belts 5, the film with adhesive on the placement roller 7 is adhered to the bottom of the foam. At the same time, the second motor 8 is started, which drives the placement roller 7 to rotate and unwind the film roll. The appliance foam board is then transported to the other first conveyor belt 5, which is simultaneously started, driving the first round shaft 4 to rotate and thus moving the other first conveyor belt 5 to transport the film-coated appliance foam board. The board continues to be conveyed to the cutting blade 10, and then the first electric telescopic rod 9 drives the cutting blade 10 to cut the film. The cut film-coated appliance foam board is then conveyed to the second conveyor belt 12. At this time, the third motor 13 on the laminating frame 1 drives the second round shaft 11 to rotate and the second conveyor belt 12 to move, so that the film-coated appliance foam board is conveyed to the push rod 14. Then the second electric telescopic rod 15 is activated, so that the push rod 14 pushes the film extending from both sides of the appliance foam board upward, so that the film finally adheres to both sides of the appliance foam board. Then the second conveyor belt 12 conveys the film-coated foam board out of the laminating frame 1 to complete the laminating process.
