Description

Technical Field

[0001] This utility model relates to the field of belt processing technology, and in particular to a compression bonding device for belt processing. Background Technology

[0002] A belt, usually referring to a leather waist belt, is an accessory used to cinch the waist, decorate, or secure clothing. It is generally made of leather or other similar materials and its tightness is adjusted by buckles or other fastening devices.

[0003] In the belt manufacturing industry, extrusion bonding is a crucial process for tightly binding the various layers of belt material into a single unit. Traditional belt extrusion bonding processes often involve manually applying adhesive to the belt before the extrusion operation. This manual application method has several drawbacks. Firstly, manual application is extremely inefficient, severely limiting the speed of large-scale belt production and making it difficult to meet the ever-increasing market demand. Secondly, it is difficult to ensure uniform application of adhesive manually, which can easily lead to inconsistent bonding strength in different parts of the belt after extrusion bonding. Areas with insufficient bonding strength are prone to delamination and peeling during subsequent use, significantly reducing the belt's lifespan and product quality.

[0004] Therefore, a compression bonding device for belt processing is needed. Utility Model Content

[0005] The main objective of this invention is to provide a compression bonding device for belt processing, which can effectively solve the problems mentioned above.

[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] Example 1, as Figure 1 and Figure 2 As shown, a belt processing extrusion bonding device includes a base plate 1, with support legs 2 fixedly connected to the four corners of the lower end of the base plate 1, a feeding module 5 fixedly connected to the right side of the upper rear part of the base plate 1, a pressing device 3 fixedly connected to the left side of the upper rear part of the base plate 1, and an adhesive applicator 4 installed on the right side of the pressing device 3.

[0027] This device can be powered by an external power source.

[0028] Before implementation, staff need to inject hot melt adhesive into the adhesive application device 4.

[0029] In the above, a rectangular plate is installed at the bottom between the pressing device 3 and the gluing device 4 for conveying the belt.

[0030] In the above process, after the hot melt adhesive is injected into the coating device 4, the worker passes half of the belt to be coated with hot melt adhesive through the upper part of the feeding module 5 and places it on the rectangular rod. Then, the worker starts the pressing device 3. When the pressing device 3 is working, it will drive the coating device 4 to rotate together. When the coating device 4 moves, it will evenly apply the hot melt adhesive to the belt. Then, the other belt is bonded to the belt coated with hot melt adhesive. Then, the bonded belt is sent into the pressing device 3. When the bonded belt enters the pressing device 3, the pressing device 3 will pull the bonded belt to the left to squeeze the belt, so that the two belts can be firmly bonded together. Finally, the bonded belt will be sent out from the left side of the pressing device 3 for natural cooling.

[0031] In the above, when the pressing device 3 pulls the belt to the left, the friction generated by the belt located below the adhesive applicator 4 will drive the adhesive applicator 4 to rotate, so that the adhesive applicator 4 will evenly apply the hot melt adhesive to the belt, so that the belt can be better bonded together when the pressing device 3 is used to press and bond the belt.

[0032] In the above process, when the hot melt adhesive in the applicator 4 is used up, the operator first closes the pressing device 3, and then manually rotates the applicator 4 to replenish the hot melt adhesive.

[0033] The device described above is used to perform a compression bonding operation on belts of unspecified size, allowing the belts to be automatically coated with adhesive before compression bonding, thereby improving work efficiency.

[0034] In Example 2, further, in order to achieve the purpose of moving the belt when the pressing device 3 is working, refer to... Figure 3 The pressing device 3 includes four arc-shaped plates 34, which are fixedly connected to the left and right sides of the upper middle and rear of the base plate 1, respectively. The upper and lower parts of the two arc-shaped plates 34 located on the front and rear sides are rotatably connected to a hot extrusion shaft 36. The front of the outer surface of the rotating shaft of each of the four hot extrusion shafts 36 is fixedly connected to a spur gear 33. The front edge of the outer surface of the rotating shaft of the two hot extrusion shafts 36 located at the lower part is fixedly connected to a belt pulley assembly 32. The front end of the hot extrusion shaft 36 located on the lower right side is fixedly connected to a stepper motor 31. The middle of the two arc-shaped plates 34 located on the front and rear sides is fixedly connected to a connecting plate 35.

[0035] Furthermore, the stepper motor 31 is fixedly connected to the upper end of the base plate 1, and two spur gears 33 located on the same side mesh with each other.

[0036] In the above process, the stepper motor 31 is started first. When the stepper motor 31 is working, its output end will rotate. When the output end of the stepper motor 31 rotates, the power can be transmitted to the hot extrusion shaft 36 located on the lower right side through the coupling. At this time, the hot extrusion shaft 36 located on the lower right side will drive the spur gear 33 and the belt pulley assembly 32 connected to it to rotate. This causes the hot extrusion shaft 36 located on the lower left side and the spur gear 33 to rotate together. At this time, the two spur gears 33 located at the lower part will drive the two hot extrusion shafts 36 located at the upper part to rotate in the opposite direction through meshing with the two spur gears 33 located at the upper part. This causes the two hot extrusion shafts 36 located at the lower part to rotate counterclockwise, while the two hot extrusion shafts 36 located at the upper part rotate clockwise. Through the friction between them and the belt, the belt is pulled and squeezed, so that the belt is bonded together by hot melt adhesive and then slides out from the left side of the device.

[0037] In the above, the belt pulley assembly 32 consists of two pulleys and a transmission belt. The two pulleys are fixedly connected to the front edge of the outer surface of the rotating shaft of the two lower hot extrusion shafts 36. The transmission belt is wound between the two pulleys. When the stepper motor 31 drives the hot extrusion shaft 36 connected to it to rotate, the rotating hot extrusion shaft 36 then rotates through the pulley connected to it. The pulley transmits power to the pulley on the left side through the transmission belt so that they rotate together, causing the hot extrusion shaft 36 on the lower left side to rotate.

[0038] Furthermore, in order to indirectly drive the adhesive application device 4 to move when the pressing device 3 moves, so that the adhesive application device 4 applies hot melt adhesive to one half of the belt, refer to... Figure 4 and Figure 5 The glue application device 4 includes a glue extrusion mechanism 45 and a support frame 43. The glue extrusion mechanism 45 is fixedly connected to the middle of the right end of the arc plate 34 located on the front right side. The glue application cylinder 46 is rotatably connected to the rear of the glue extrusion mechanism 45. The rear end of the glue application cylinder 46 is rotatably connected to a fixed plate 47. The front end of the glue extrusion mechanism 45 is fixedly connected to a friction wheel 44. The support frame 43 is fixedly connected to the front right side of the upper end of the base plate 1. The left rear end of the support frame 43 is rotatably connected to an arc friction wheel 42. The rear part of the outer surface of the rotating shaft of the arc friction wheel 42 and the output end of the stepper motor 31 are both fixedly connected to a belt pulley assembly 41. The rear end of the rotating shaft of the arc friction wheel 42 is rotatably connected to a support plate 48.

[0039] Furthermore, the lower end of the support plate 48 is fixedly connected to the upper end of the base plate 1, the friction wheel 44 is rotatably connected to the upper right side of the rear end of the support frame 43, and the left end of the fixing plate 47 is fixedly connected to the right end of the arc plate 34 located on the rear right side.

[0040] Furthermore, the extrusion mechanism 45 includes a glue storage tank 451, which is fixedly connected to the middle of the right end of the arc plate 34 located on the front right side. A glue inlet 452 is fixedly connected to the middle of the rear end of the upper part of the glue storage tank 451. A threaded shell 455 is slidably connected to the middle of the rear end of the glue storage tank 451. A threaded rod 454 is threadedly connected to the inner surface of the threaded shell 455. An extrusion plate 453 is rotatably connected to the front end of the threaded shell 455.

[0041] Furthermore, the extrusion plate 453 slides on the inner surface of the glue storage tank 451, and the rear end of the threaded rod 454 is fixedly connected to the front end of the friction wheel 44.

[0042] In the above description, when the output of the stepper motor 31 rotates, it drives the belt pulley assembly 41 to move together. At this time, the belt pulley assembly 41 drives the arc-shaped friction wheel 42 to rotate together. Because the arc-shaped friction wheel 42 is in contact with the friction wheel 44, the friction between the arc-shaped friction wheel 42 and the friction wheel 44 will drive the friction wheel 44 to rotate together. When the friction wheel 44 rotates, it will drive the threaded rod 454 to rotate. The threaded rod 454, through its threaded connection with the threaded housing 455, will drive... The moving threaded housing 455 moves backward, causing the extrusion plate 453 to move backward as well. This causes the extrusion plate 453 to squeeze the hot melt adhesive in the glue storage tank 451 into the coating cylinder 46. The coating cylinder 46 then squeezes the hot melt adhesive out through the filter holes on its outer surface and drips it onto the belt. The outer surfaces of the coating cylinder 46 are in contact with each other, and the hot melt adhesive base is on the belt. When the belt is pulled by the pressing device 3, the friction will cause the coating cylinder 46 to rotate together, so that the coating cylinder 46 can evenly apply the hot melt adhesive onto the belt.

[0043] In the above, the arc-shaped friction wheel 42, through the design of the cam, will indirectly drive the friction wheel 44 to rotate when the arc-shaped friction wheel 42 rotates, so that the threaded rod 454 pushes the extrusion plate 453 to move forward slowly, thereby preventing the hot melt adhesive from being squeezed out in excess.

[0044] In the above process, after the hot melt adhesive in the glue storage tank 451 is used up, the operator turns off the stepper motor 31 to stop it from working. At this time, the arc-shaped friction wheel 42 will also stop rotating. Then, the operator manually rotates the friction wheel 44 in the opposite direction, so that the friction wheel 44 drives the extrusion plate 453 to move backward through the threaded rod 454 and the threaded shell 455. After the extrusion plate 453 moves back to the initial position, the operator injects the hot melt adhesive into the glue storage tank 451 through the glue inlet 452.

[0045] In the above, the glue inlet 452 is a one-way valve, so that when the extrusion plate 453 extrudes the hot melt adhesive, the hot melt adhesive will not flow out from the glue inlet 452.

[0046] In the above, the hot melt adhesive has poor flowability. The filter holes on the coating tube 46 can effectively restrict the hot melt adhesive, and without external force, the hot melt adhesive cannot flow out of the coating tube 46.

[0047] It should be noted that the specific installation method, circuit connection method, and control method of the stepper motor 31 used in this utility model are all conventional designs, and will not be described in detail in this utility model.

[0048] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
