[0002] The zipper rubberizing machine is a zip fastener production equipment, which is used for welding the rubberized tape on the zip fastener belt, thereby enhancing the opening and closing flat pulling strength and socket displacement capacity. The zip fastener belt is an intermediate product in the zip fastener production process, which includes two cloth belts and two sections of intermeshing zipper teeth. The two sections of zipper teeth are arranged on the two cloth belts in one-to-one correspondence. The zip fastener belt can adopt nylon, metal or plastic material zipper teeth according to actual needs.

[0003] The existing zipper rubberizing machine usually includes a rubber feeding mechanism and an ultrasonic welding mechanism. The ultrasonic welding mechanism includes a welding die and a welding head. The welding die and the welding head are used to place the welding part of the zip fastener belt therebetween. The rubberized tape is fed to the front and back surfaces of the zip fastener belt by the rubber feeding mechanism, and then the rubberized tape is welded on the zip fastener belt by the ultrasonic welding mechanism.

[0004] However, the ultrasonic welding is a technology of using high-frequency ultrasonic vibration to generate friction heat on the contact surface of the workpiece, thereby realizing the connection or sealing between materials, that is, the welding process is accompanied by high-frequency vibration. When the zip fastener belt adopts nylon material zipper teeth and is welded by the existing zipper rubberizing machine, the zipper teeth near the welding part of the zip fastener belt will be affected by the vibration of the welding head and vibrate synchronously, so that the two sections of zipper teeth near the welding part of the zip fastener belt rub against each other, thereby damaging the zipper teeth and generating burrs, and further causing the produced zip fastener product to jam at the damaged zipper teeth, thereby affecting the smoothness of the zip fastener.

[0036] Referring to Figure 1 With Figure 2 The fixed plate 1 is in the shape of a long strip, and the length direction of the fixed plate 1 is the pressurizing direction. One side of the fixed plate 1 is the abutting side 6, which is adapted to the shape of the flower model, so that when the fixed plate 1 is driven to abut on the flower model, the abutting side 6 is aligned and abuts on the flower model, thereby reducing the gap between the fixed plate 1 and the flower film. In addition, one end of the fixed plate 1 is the pressurizing end 4, which is directed towards the teeth of the zipper tape when the abutting side 6 is driven to abut on the flower model, thereby playing a role of rapid alignment through the abutting side 6, reducing the time of alignment installation of the fixed plate 1.

[0037] Continue to refer to Figure 1 With Figure 2The fixing plate 1 is provided with a mounting hole 10, which is circular and penetrates the front and back surfaces of the fixing plate 1. The fixing plate 1 is also provided with bolts (not shown in the figure), which are matched with the mounting hole 10 and are threadedly matched with the flower mold. When the fixing plate 1 is installed on the flower mold, the driving abutting side 6 is aligned and abuts on the flower mold, the pressing end 4 faces the teeth of the zipper tape, the bolts are inserted into the mounting hole 10 and the flower mold, and the bolts are threadedly matched with the flower mold, so that the fixing plate 1 can be conveniently connected to the flower mold. Then, the pressing chain slider 2 is driven to slide, the pressing block 3 is driven to move, and the pressing block 3 abuts on the teeth of the zipper tape.

[0038] Specifically, referring to Figure 3 and Figure 4 , the pressing chain slider 2 comprises an integrally formed driving part 21, a sliding part 22 and a limiting part 23.

[0039] Referring to Figure 3 and Figure 4 , the abutting side 6 of the fixing plate 1 is provided with a first sliding groove 7, which penetrates the pressing end 4, and the limiting part 23 is slidably matched with the first sliding groove 7 in the pressing direction. The bottom of the first sliding groove 7 is also provided with a second sliding groove 8, which is square and penetrates the fixing plate 1. The sliding part 22 is slidably matched with the second sliding groove 8 in the pressing direction, so that the position of the sliding part 22 can be observed from the outside. Thus, the second sliding groove 8 limits the pressing chain slider 2 from being vertically separated from the fixing plate 1.

[0040] Referring to Figure 1 and Figure 3 , the fixing plate 1 is provided with a cover plate 9, which is rectangular and distributed along the length direction of the fixing plate 1. The cover plate 9 is connected to the abutting side 6 of the fixing plate 1 by bolts, and two cover plates 9 are oppositely distributed along the width direction of the fixing plate 1. The two cover plates 9 limit the limiting part 23, so that the pressing chain slider 2 cannot be separated from the fixing plate 1 in the transverse direction, and the driving part 21 protrudes from the abutting side 6 of the fixing plate 1.

[0041] When the pressing chain slider 2 is driven to slide, the limiting part 23 slides in the first sliding groove 7 in the pressing direction, and the sliding part 22 slides in the second sliding groove 8 in the pressing direction, so that the sliding process is more stable. The second sliding groove 8 limits the pressing chain slider 2 from being vertically separated from the fixing plate 1, and the two cover plates 9 limit the limiting part 23, so that the pressing chain slider 2 cannot be separated from the fixing plate 1 in the transverse direction.
