Description

Technical Field

[0001] The utility model belongs to the technical field of hot melt welders, in particular to a hot melt welder for a laminating machine. Background Art

[0002] A hot melt welder for a laminating machine is a device used to coat the surface of a product with hot melt adhesive in industrial production. It achieves the purpose of waterproofing, dustproofing or protection by evenly applying the hot melt adhesive to a film or substrate and bonding it to the surface of the product. The heating roller, as a key part of the hot melt welder for a laminating machine, is responsible for providing heat to melt the hot melt adhesive and ensure that it can be evenly coated on the film or substrate. However, if there are residues on the surface of the heating roller, such as adhesives, adhesive films or other impurities, the bonding between the film and the object to be coated will not be firm during the laminating process, resulting in bubbles, wrinkles or delamination, which seriously affect the appearance and quality of the laminated product.

[0022] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following embodiments. It should be understood that the following text is only used to describe one or several specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0023] like Figures 1 to 4As shown, a hot melt welder for a laminating machine includes a base 10, and brackets 11 are provided on both sides of the upper end of the base 10. A first rotating rod 12 and an active roller 13 are rotatably connected between the two brackets 11 from top to bottom. A first motor 14 is provided on the upper end of the base 10 and on one side of the bracket 11. The output end of the first motor 14 passes through the bracket 11 and is fixedly connected to the active roller 13. A second motor 15 is provided on the upper end of one bracket 11, and a fixed block 16 is provided on the upper end of one bracket 11. A first threaded rod 17 is fixed to the output end of the second motor 15, and the first threaded rod 17 extends to the inside of the fixed block 16 away from the side of the second motor 15. A second rotating rod 18 is fixed to the side of the fixed block 16 close to the first threaded rod 17. A moving block 19 is rotatably connected to the outer side of the first threaded rod 17, and the second rotating rod 18 passes through both sides of the moving block 19. A cleaning mechanism 20 is assembled on the upper end of the moving block 19, and the cleaning mechanism 20 includes a support plate 21 , the third motor 22, the first gear 23, the second threaded rod 24, the second gear 25, the limiting rod 26, the clamping plate 27 and the bristles 28, the support plate 21 is fixed to the upper end of the moving block 19, the third motor 22 is arranged at one end of the support plate 21, and the output end of the third motor 22 extends to the inside of the support plate 21, the first gear 23 is fixed to the output end of the third motor 22 and is located inside the support plate 21, the second threaded rod 24 passes through both ends of the support plate 21, and the second threaded rod 24 and the support plate 21 are rotatably connected, the second gear 25 is fixed to the outside of the second threaded rod 24 and is located at the lower end of the first gear 23, and the first gear 23 and the second gear 25 are meshed and connected, the limiting rod 26 passes through both ends of the support plate 21, and the limiting rod 26 and the support plate 21 are fixedly connected, the two clamping plates 27 are threadedly connected to the two ends of the second threaded rod 24, and are slidably connected to the limiting rod 26, and a plurality of bristles 28 are arranged on a side of the lower ends of the two clamping plates 27 close to each other.

[0024] In the above-mentioned implementation, when the heating roller 34 needs to be cleaned, the third motor 22 starts to rotate, and the rotation of the third motor 22 drives the first gear 23 to rotate. Because the first gear 23 and the second gear 25 are meshed and connected, when the first gear 23 rotates, the second gear 25 rotates. Because the second threaded rod 24 passes through the second gear 25 and extends to the two ends of the support plate 21, when the second gear 25 rotates, the second threaded rod 24 rotates. Both ends of the second threaded rod 24 are rotated and connected with the clamping plate 27. (It should be noted that the second threaded rod 24 is Both ends are provided with threads, and the directions of the threads are different. When the second threaded rod 24 rotates, the two clamps 27 will approach each other or move away from each other). The side of the two clamps 27 close to each other is provided with bristles 28. When the two clamps 27 move to the outside of the heating roller 34 when the bristles 28 can contact the outside of the heating roller 34, they no longer move. At this time, the second motor 15 starts to rotate, and the rotation of the second motor 15 drives the moving block 19 to move. Because the cleaning mechanism 20 is assembled at the upper end of the moving block 19, the cleaning mechanism 20 can reciprocate to clean the heating roller 34 through the bristles 28.

[0025] Furthermore, the bristles 28 are made of a flexible material.

[0026] In this manner, the flexible bristles 28 can better conform to the surface of the heating roller 34 and penetrate deep into its grooves and crevices, effectively removing residue and dirt. This ensures a thorough cleaning process and improves the quality of the coated product. Furthermore, the flexible bristles 28 are soft and durable, and they do not scratch or abrade the surface of the heating roller 34 during the cleaning process. This helps extend the service life of the heating roller 34 and maintain its good working condition.

[0027] Furthermore, a fourth motor 29 is provided at the upper end of the bracket 11 and at one end of the second motor 15, and a third gear 30 is fixed to the output end of the fourth motor 29. The side of the first rotating rod 12 close to the fourth motor 29 passes through the bracket 11 and extends to the lower end of the third gear 30. A fourth gear 31 is fixed to the outside of the first rotating rod 12 and at the lower end of the third gear 30, and the third gear 30 and the fourth gear 31 are meshed and connected.

[0028] In the implementation of the above method, when the heating roller 34 needs to be cleaned, the heating roller 34 needs to be rotated for easy cleaning. The third gear 30 is driven to rotate by the fourth motor 29. Because the third gear 30 and the fourth gear 31 are engaged and connected, when the third gear 30 rotates, the fourth gear 31 rotates, and the rotation of the fourth gear 31 drives the first rotating rod 12 to rotate. Two receiving rods 33 are provided at the lower end of the first rotating rod 12, and a heating roller 34 is provided between the two receiving rods 33. The rotation of the first rotating rod 12 can cause the heating roller 34 to rotate.

[0029] like Figure 1、 Figure 5 and Figure 6 As shown, a first groove is provided at one end of the first rotating rod 12 close to the cleaning mechanism 20, and a third rotating rod 32 is arranged in the first groove. The third rotating rod 32 and the first rotating rod 12 are fixedly connected by bolts, and the third rotating rod 32 and the first rotating rod 12 are adapted to each other. A receiving rod 33 is provided on both sides of the first rotating rod 12, and a heating roller 34 is provided between the two receiving rods 33.

[0030] Furthermore, in the above-mentioned implementation, the connection between the third rotating rod 32 and the first rotating rod 12 is more secure through the bolted connection, and can withstand greater torque and force.

[0031] Furthermore, the two receiving rods 33 are provided with multiple second grooves from top to bottom at one end close to the first rotating rod 12, and the first rotating rod 12 is provided with first through holes on both sides of one end close to the two receiving rods 33, and multiple clamping plates 35 are provided inside the two first through holes, and the multiple second grooves are clamped with the multiple clamping plates 35.

[0032] In the above-mentioned implementation, when the height of the heating roller 34 needs to be adjusted, the two receiving rods 33 are moved upward or downward. A plurality of second grooves are provided on the two receiving rods 33, and the plurality of second grooves and the plurality of clamping plates 35 can be clamped. At the same time, the two receiving rods 33 can be fixed on the first rotating rod 12 by fixing the third rotating rod 32 and the first rotating rod 12 with bolts.

[0033] Furthermore, positioning holes are provided on both sides of the bolt at one end of the first rotating rod 12 close to the third rotating rod 32, and positioning pins 36 are provided on both sides of the third rotating rod 32 close to the first rotating rod 12, and the two positioning pins 36 are adapted to the two positioning holes.

[0034] In the above implementation, the two positioning pins 36 are matched with the two positioning holes. After the positioning pins 36 are inserted into the positioning holes, the relative movement between the third rotating rod 32 and the first rotating rod 12 can be effectively prevented.

[0035] The working principle of this utility model is:

[0036] When it is necessary to clean the heating roller 34, the fourth motor 29 rotates to drive the third gear 30 and the fourth gear 31 to rotate, and the fourth gear 31 rotates to drive the first rotating rod 12, the two receiving rods 33 and the heating roller 34 to rotate. The heating roller 34 stops rotating when it rotates a quarter of a cycle. At this time, the third motor 22 starts to rotate, and the third motor 22 rotates to drive the first gear 23 and the second gear 25 to rotate. When the second gear 25 rotates, the second threaded rod 24 rotates. Both ends of the second threaded rod 24 are rotatably connected to the splint 27. When the two splints 27 approach each other until the bristles 28 can contact the outside of the heating roller 34, they no longer move. At this time, the second motor 15 starts to rotate, and the second motor 15 rotates to drive the moving block 19 to move. Because the cleaning mechanism 20 is assembled at the upper end of the moving block 19, the cleaning mechanism 20 can reciprocate to clean the heating roller 34 through the bristles 28.

[0037] The above description is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications should be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention shall, unless otherwise specified or limited, be implemented in accordance with conventional means in the art.
