This not only affects the uniformity of subsequent lamination but may also damage the foam board during the cutting process, affecting the quality of the final product. Utility Model Content

[0004] The technical problem this utility model aims to solve is that when using a laminating machine to process the bottom of household appliance foam, in the traditional laminating process of household appliance foam base, the foam board may be unstable in position during the conveyor belt process, resulting in uneven spacing between adjacent foam boards. This not only affects the uniformity of subsequent lamination, but may also cause damage to the foam board during the cutting process, affecting the quality of the final product.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a foam base type laminating machine for household appliances, including a laminating frame and two first conveyor belts. A control box is provided on one side of the laminating frame. Several first round shafts are symmetrically installed through the inner wall of the laminating frame. The two first conveyor belts are respectively sleeved on the outer surfaces of two opposite first round shafts. A first motor is symmetrically fixedly installed on one side of the laminating frame. The output end of the first motor is fixedly installed on one side of one of the first round shafts by means of a coupling. A placement roller is installed through the inner wall of the laminating frame. A second motor is fixedly installed on one side of the laminating frame. The output end of the second motor is fixedly installed on one side of the placement roller by means of a coupling. The placement roller is disposed between the two first conveyor belts. A first electric telescopic rod is fixedly installed on one side of the inner wall of the laminating frame. A cutting blade is fixedly installed on the output rod of the first electric telescopic rod. The inner wall of the laminating frame is symmetrically fitted with second round shafts, and a second conveyor belt is fitted onto the outer surface of the second round shafts. A third motor is fixedly installed on one side of the laminating frame, and the output end of the third motor is fixedly installed on one side of one of the second round shafts via a coupling. The cutting blade is positioned between the second conveyor belt and the first conveyor belt. The inner wall of the laminating frame is fixedly fitted with second electric telescopic rods on both sides of the third conveyor belt, and a push rod is fixedly installed on the output rod of the second electric telescopic rod. Limit frames are symmetrically arranged on the top of the laminating frame. An auxiliary device is arranged at the end of the top of the laminating frame away from the second conveyor belt from the first conveyor belt. The auxiliary device can drive the slide and baffle to move up and down intermittently with the third electric telescopic rod to block the conveying appliance foam boards, thereby achieving a uniform distance between adjacent appliance foam boards in subsequent conveying.

[0006] The effect achieved by the above components is as follows: When using a laminating machine to laminate the bottom of a household appliance foam board, firstly, a laminating roll with adhesive is 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 household appliance foam board. Simultaneously, an auxiliary device is activated to intermittently block the conveying household appliance foam board. When the board is transported between two first conveyor belts, the adhesive film on the placement roller is adhered to the bottom of the foam. At the same time, a second motor is started, driving the placement roller to rotate and unwind the laminating roll. Then, the household appliance foam board continues to be transported to the other conveyor belt. On the first conveyor belt, and simultaneously, another first conveyor belt is started, driving the first round shaft to rotate, thereby driving the second first conveyor belt to continue conveying the appliance foam board with film to the cutting knife. Then, the first electric telescopic rod drives the cutting knife to cut the film. The cut appliance foam board is then conveyed to the second conveyor belt. At this time, the third motor on the laminating machine frame drives the second round shaft to rotate, moving the second conveyor belt, so that the appliance foam board with film is conveyed to the push rod. Then, the second electric telescopic rod is started, so that the push rod 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 foam board with film out of the laminating machine frame, thus completing the laminating process.

[0007] Preferably, the auxiliary device includes a bracket, with detachable devices between both ends of the bracket and the top of the laminating machine frame, and sliding grooves on both sides of the bracket; a third electric telescopic rod, one side of which is fixedly mounted on one side of the bracket; a slide, one side of which is fixedly mounted on the output rod of the third electric telescopic rod, and both ends are slidably mounted in the inner wall of the sliding groove; and a baffle, one side of which is fixedly mounted on one side of the slide.

[0008] The effect achieved by the above-mentioned components is as follows: By setting up auxiliary devices, when the appliance foam board is placed on the first transmission belt for conveying, the third electric telescopic rod on the bracket can be activated by the control box to drive the slide to move up and down in the slide groove at intervals, thereby driving the baffle to move up and down, blocking and isolating the adjacent appliance foam boards during the conveying process, controlling the spacing between adjacent foam boards to keep it consistent, thereby ensuring the smooth progress of the subsequent lamination process, avoiding damage to the foam board during the cutting process, and significantly improving production efficiency and product quality.

[0009] Preferably, the auxiliary device further includes several circular rollers, which are rotatably mounted at equal intervals on both sides of the baffle.

[0010] The effect achieved by the above components is that by setting the roller, the wear between the baffle and the appliance foam board support can be reduced, and the baffle can be easily inserted between two adjacent appliance foam boards for blocking.

[0011] Preferably, the auxiliary device further includes two reinforcing rods, wherein the two sides of the reinforcing rods are respectively fixedly installed on the outer surface of the output rod of the third electric telescopic rod and on one side of the carriage.

[0012] The effect achieved by the above components is that by setting up reinforcing rods, the connection area between the output rod of the third electric telescopic rod and the carriage can be increased, making the connection more secure and less prone to breakage or damage.

[0013] Preferably, the detachable device includes a locking block, with locking slots on both sides of the laminating machine frame, one end of the bracket inserted into the inner wall of the locking slot, a locking hole on one side of the inner wall of the locking slot, rectangular slots on both sides of the bracket, one end of the locking block slidably mounted in the inner wall of the rectangular slot, and the other end inserted in the inner wall of the locking hole; and a spring, wherein the two ends of the spring are respectively fixedly mounted on one side of the locking block and one side of the inner wall of the rectangular slot.

[0014] The effect achieved by the above components is as follows: by setting a detachable device, when it is necessary to maintain or replace the bracket and the third electric telescopic rod, the locking block can be manually pressed inward in the rectangular groove to a certain position, which will cause the spring to contract and pull one end of it out of the locking hole. Then, by pulling the bracket upward, one end of it can be pulled out of the locking groove, so that the bracket can be removed from the laminating machine frame for easy maintenance and replacement.

[0015] Preferably, the longitudinal section of the locking block is U-shaped, and the height of the end of the locking block near the third electric telescopic rod is higher than that of the other end.

[0016] The effect achieved by the above-mentioned components is that by designing one end of the locking block to be higher than the other end, it is convenient to press it during disassembly, thus facilitating disassembly.

[0017] Preferably, both ends of the bracket are chamfered.

[0018] The effect achieved by the above components is that by providing chamfers on both sides of the bracket, the area at both ends of the bracket can be reduced, making it easier to quickly align with the slots and insert them, thus facilitating installation.

[0019] Preferably, the detachable device further includes a limiting telescopic rod, wherein the outer surface of the limiting telescopic rod is installed through the inner wall of the spring, and both ends are respectively fixedly installed on one side of the locking block and one side of the inner wall of the rectangular groove.

[0020] The effect achieved by the above components is that by setting the limiting telescopic rod, the inner wall of the spring can be supported and reinforced, making it less prone to damage during use and increasing the service life of the spring.

[0021] The beneficial effects of this utility model are:

[0022] By setting up an auxiliary device, when the appliance foam board is placed on the first transmission belt for conveying, the third electric telescopic rod on the control box can be activated to drive the slide to move up and down in the slide groove at intervals. This, in turn, drives the baffle to move up and down, blocking and isolating adjacent appliance foam boards during the conveying process, controlling the spacing between adjacent foam boards to keep it consistent, thus ensuring the smooth progress of the subsequent lamination process and avoiding damage to the foam board during the cutting process. This significantly improves production efficiency and product quality. Attached Figure Description

[0032] Figure 1-5The appliance foam base type laminating machine shown includes a laminating frame 1 and two first conveyor belts 6. A control box 4 is provided on one side of the laminating frame 1. Several first round shafts 5 are symmetrically installed through the inner wall of the laminating frame 1. The two first conveyor belts 6 are respectively sleeved on the outer surfaces of two opposite first round shafts 5. A first motor 7 is symmetrically fixedly installed on one side of the laminating frame 1. The output end of the first motor 7 is fixedly installed on one side of one of the first round shafts 5 by means of a coupling. A placement roller 8 is installed through the inner wall of the laminating frame 1. A second motor 9 is fixedly installed on one side of the laminating frame 1. The output end of the second motor 9 is fixedly installed on one side of the placement roller 8 by means of a coupling. The placement roller 8 is located between the two first conveyor belts 6. A first electric telescopic rod 11 is fixedly installed on one side of the inner wall of the laminating frame 1. A cutting blade 10 is fixedly installed on the output rod of the first electric telescopic rod 11. A second electric telescopic rod 11 is symmetrically installed through the inner wall of the laminating frame 1. Two circular shafts 12 are mounted on their outer surfaces, with a second conveyor belt 13 fitted onto them. A third motor 14 is fixedly mounted on one side of the laminating frame 1, with the output end of the third motor 14 fixedly mounted on one side of one of the second circular shafts 12 via a coupling. A cutting blade 10 is positioned between the second conveyor belt 13 and the first conveyor belt 6. Second electric telescopic rods 15 are fixedly mounted on the inner walls of the laminating frame 1 on both sides of the third conveyor belt. A push rod 16 is fixedly mounted on the output rod of the second electric telescopic rod 15. Limit frames 17 are symmetrically arranged on the top of the laminating frame 1. An auxiliary device 2 is located at the end of the first conveyor belt 6 away from the second conveyor belt 13 on the top of the laminating frame 1. The auxiliary device 2 can drive the slide 24 and the baffle 25 to move up and down intermittently via the third electric telescopic rod 23 to block the conveyed appliance foam boards, thereby achieving a uniform distance between adjacent appliance foam boards in subsequent conveying.When using a laminating machine to laminate the bottom of appliance foam boards, first, a laminating roll with adhesive is mounted on the placement roller 8. Then, the appliance foam board is placed on one of the first conveyor belts 6. Operating via the control box 4, one of the first motors 7 is started, driving one of the first cylindrical shafts 5 to rotate, which in turn drives the first conveyor belt 6 to convey the appliance foam board. Simultaneously, the auxiliary device 2 is activated to intermittently block the conveying appliance foam board. When the foam board is conveyed between two first conveyor belts 6, the adhesive film on the placement roller 8 is adhered to the bottom of the foam. At the same time, the second motor 9 is started, driving the placement roller 8 to rotate and unwind the laminating roll. The appliance foam board is then conveyed to the other first conveyor belt 6, which is simultaneously started, driving the first cylindrical shaft 5 to rotate and thus drive the other first conveyor belt 6 to adhere the film. The laminated appliance foam board continues to be conveyed to the cutting blade 10. Then, the first electric telescopic rod 11 drives the cutting blade 10 to cut the film. The cut laminated appliance foam board is then conveyed to the second conveyor belt 13. At this time, the third motor 14 on the laminating frame 1 drives the second round shaft 12 to rotate, moving the second conveyor belt 13. This allows the laminated appliance foam board to be conveyed to the push rod 16. Then, the second electric telescopic rod 15 is activated, causing the push rod 16 to push the film extending from both sides of the appliance foam board upwards, so that the film finally adheres to both sides of the appliance foam board. Then, the second conveyor belt 13 conveys the laminated foam board out of the laminating frame 1, completing the laminating process. During the movement of the appliance foam board, the limiting frame 17 on the laminating frame 1 is used to limit the upper end of the appliance foam board, ensuring that the foam board remains in contact with the first conveyor belt 6 and the second conveyor belt 13. It should be noted that the control box 4 is a mature technology and equipment in the prior art, and its internal structure, connection method, and principle will not be described further.

[0033] Figure 1-5The auxiliary device 2 shown includes a bracket 21, with detachable devices 3 between both ends of the bracket 21 and the top of the laminating machine frame 1. Slide grooves 22 are provided on both sides of the bracket 21. A third electric telescopic rod 23 is fixedly mounted on one side of the bracket 21. A slide 24 is fixedly mounted on one side of the output rod of the third electric telescopic rod 23, and its two ends are slidably mounted in the inner wall of the slide groove 22. A baffle 25 is fixedly mounted on one side of the slide 24. When the appliance foam board is placed on the first transmission belt for conveying, the control box 4 can activate the third electric telescopic rod 23 on the bracket 21 to intermittently drive the slide 24 to move up and down in the slide groove 22, thereby driving the baffle 25 to move up and down. This blocks and isolates adjacent appliance foam boards during the conveying process, controlling the spacing between adjacent foam boards to maintain consistency, thus ensuring the smooth progress of the subsequent laminating process and avoiding damage to the foam boards during cutting, significantly improving production efficiency and product quality.

[0034] Figure 1-5 The auxiliary device 2 also includes several rollers 26, which are equidistantly mounted on both sides of the baffle 25. By installing the rollers 26, wear between the baffle 25 and the appliance foam board support 21 can be reduced, and the baffle 25 can be easily inserted between two adjacent appliance foam boards for blocking. The auxiliary device 2 also includes two reinforcing rods 27, which are fixedly mounted on the outer surface of the output rod of the third electric telescopic rod 23 and one side of the slide 24, respectively. By installing the reinforcing rods 27, the connection area between the output rod of the third electric telescopic rod 23 and the slide 24 can be increased, making the connection more secure and less prone to breakage.

[0035] Figure 1-5 The detachable device 3 shown includes a locking block 35. The laminating machine frame 1 has locking slots 31 on both sides. One end of the bracket 21 is inserted into the inner wall of the locking slot 31. A locking hole 32 is provided on one side of the inner wall of the locking slot 31. Rectangular grooves 33 are provided on both sides of the bracket 21. One end of the locking block 35 is slidably installed in the inner wall of the rectangular groove 33, and the other end is inserted into the inner wall of the locking hole 32. A spring 34 is also included, with both ends fixedly installed on one side of the locking block 35 and one side of the inner wall of the rectangular groove 33, respectively. By providing the detachable device 3, when maintenance or replacement of the bracket 21 and the third electric telescopic rod 23 is required, the locking block 35 can be manually pressed inward in the rectangular groove 33 to a certain position, causing the spring 34 to retract and pull one end out of the locking hole 32. Then, by pulling the bracket 21 upward, one end can be pulled out of the locking slot 31, allowing the bracket 21 to be removed from the laminating machine frame 1 for easy maintenance and replacement.

[0036] Figure 1-5 The longitudinal section of the shown locking block 35 is U-shaped, with the end of the locking block 35 closest to the third electric telescopic rod 23 being higher than the other end. Designing one end of the locking block 35 to be higher than the other facilitates pressing during disassembly, making disassembly easier. Both ends of the bracket 21 have chamfered edges. Chamfering at both ends of the bracket 21 reduces the area at both ends, facilitating quick alignment with the locking slot 31 and insertion, thus simplifying installation. The detachable device 3 also includes a limiting telescopic rod 36, whose outer surface is installed through the inner wall of the spring 34, with both ends fixedly installed on one side of the locking block 35 and one side of the inner wall of the rectangular groove 33, respectively. The limiting telescopic rod 36 reinforces and supports the inner wall of the spring 34, preventing damage during use and extending the service life of the spring 34.

[0037] Working Principle: When using a laminating machine to laminate the bottom of appliance foam boards, the laminating roll with adhesive is first installed on the placement roller 8. Then, the appliance foam board is placed on one of the first conveyor belts 6. The control box 4 operates by starting one of the first motors 7, which drives one of the first shafts 5 to rotate. This drives the first conveyor belt 6 to convey the appliance foam board. During conveying, the control box 4 can activate the third electric telescopic rod 23 on the bracket 21 to periodically move the slide 24 up and down in the slide groove 22, thereby causing the baffle 25 to move up and down. This blocks and isolates adjacent appliance foam boards during conveying, maintaining a consistent spacing between adjacent foam boards. This ensures the smooth progress of subsequent laminating processes and prevents damage to the foam board during cutting, significantly improving production efficiency and product quality. When the foam board is conveyed between the two first conveyor belts 6, the adhesive-laden film on the placement roller 8 is adhered to the bottom of the foam board. Simultaneously, the second motor 9 is started to rotate the placement roller 8 to laminate the foam board. The roll is unwound, and then the appliance foam board is conveyed to another first conveyor belt 6. At the same time, the other first conveyor belt 6 is started, driving the first round shaft 5 to rotate, which in turn drives the other first conveyor belt 6 to continue conveying the appliance foam board with the film to the cutting knife 10. Then, the first electric telescopic rod 11 drives the cutting knife 10 to cut the film. The cut appliance foam board is then conveyed to the second conveyor belt 13. At this time, the third motor 14 on the laminating frame 1 drives the second round shaft 12 to rotate the second conveyor belt. 13 moves to convey the laminated appliance foam board to push rod 16, then the second electric telescopic rod 15 is activated, causing push rod 16 to push the film extending from both sides of the appliance foam board upwards, so that the film finally adheres to both sides of the appliance foam board. Then the second conveyor belt 13 conveys the laminated foam board out of the laminating frame 1 to complete the laminating process. When the appliance foam board moves, the limiting frame 17 on the laminating frame 1 is used to limit the upper end of the appliance foam board, so that the foam board always adheres to the first conveyor belt 6 and the second conveyor belt 13.

[0038] When maintenance or replacement of the bracket 21 and the third electric telescopic rod 23 is required, the locking block 35 can be manually pressed inward in the rectangular groove 33 to a certain position, which will cause the spring 34 to retract and pull one end out of the locking hole 32. Then, the bracket 21 can be pulled upward to pull one end out of the locking groove 31, so that the bracket 21 can be removed from the laminating machine frame 1 for easy maintenance and replacement.

[0039] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
