[0002] Zippers are a commonly used accessory, which are widely used in various daily necessities such as clothes and bags. During the zipper production process, the semi-finished zipper contains many zipper monomers, which need to be cut so that each zipper monomer is separated to form a finished zipper. In the prior art, patent CN 110640804 A discloses a typical zipper cutting mechanism, which cuts the semi-finished zipper through an ultrasonic generator and a cutter. In this structure, sometimes when the cutter leaves the zipper after the cutting operation, the zippers may still be stuck together and the zipper ends cannot be well post-processed. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides an automatic cutting device for semi-finished zippers, which can solve the adhesion problem and perform post-processing on the ends of the zippers.

[0004] Technical solution: To achieve the above-mentioned purpose, the utility model provides an automatic cutting device for semi-finished zippers, which includes a cutting seat and a cutting knife capable of vertically moving relative to the upper end surface of the cutting seat, and also includes an ultrasonic device connected to the cutting knife; the ultrasonic device and the cutting knife are both driven to descend by a vertical moving module;

[0005] It also includes a press edge separation assembly installed at the lower end of the cutting knife;

[0006] The edge pressing and separation assembly comprises an assembly seat fixed relative to the cutting knife, and also comprises two edge pressing blocks capable of sliding relative to the assembly seat; the edge pressing blocks can elastically slide in a vertical direction relative to the assembly seat, and the two edge pressing blocks can open and close relative to each other;

[0007] During operation, the edge pressing block contacts the semi-finished zipper product before the cutting knife.

[0008] Furthermore, a rubber block is fixed at the bottom of the edge pressing block.

[0009] Further, the edge pressing blocks are connected to the component seats through sliding seats respectively; the sliding seats can slide horizontally relative to the component seats; the edge pressing blocks slide vertically relative to the sliding seats, and a first spring is arranged between the two;

[0010] The edge pressing and separating assembly further comprises a sliding sleeve capable of vertically sliding relative to the assembly seat, a second spring is arranged between the sliding sleeve and the cutting knife; a connecting rod is respectively connected between the sliding sleeve and each of the sliding seats, and both ends of the connecting rod are rotatably connected to the sliding sleeve and the sliding seat respectively. The rigidity of the second spring is greater than that of the first spring.

[0011] Furthermore, the sliding sleeve is sleeved on the outer side of the cutting knife, a convex shoulder portion is formed on the cutting knife, and the first spring is placed between the convex shoulder portion and the sliding sleeve.

[0012] Furthermore, the lower end of the cutting knife has a cutting edge, and both sides of the cutting edge have flat portions respectively; and a clearance groove is provided on the upper end surface of the cutting seat body at a position corresponding to the position directly below the cutting edge.

[0013] During operation, the vertical moving module makes the cutting knife move downward. When the cutting knife descends, the rubber block at the bottom of the edge pressing block first contacts the semi-finished zipper being cut. As the cutting knife descends, the edge pressing block first deforms the first spring, so that there is sufficient friction between the rubber block and the semi-finished zipper. Then, when the edge pressing block rises to the limit relative to the sliding seat and the cutting knife continues to descend, the sliding seat acts on the sliding sleeve through the connecting rod, and the sliding sleeve compresses the second spring. Thereafter, the cutting edge cuts the semi-finished zipper, and the force of the second spring causes the sliding sleeve to move downward. The sliding sleeve separates the two sliding seats from each other through the connecting rod. The two ends formed after the semi-finished zipper is cut are also separated and pressed by two plane parts respectively. The ultrasonic device acts on the two ends through the plane part, and the two ends can be post-processed so that the ends will not form burrs and will not easily crack.

[0014] Beneficial effects: The automatic cutting device for semi-finished zippers of the utility model can press the edges of the semi-finished zippers when the cutting knife is performing the cutting operation, and can separate the two ends formed by the cutting after the semi-finished zipper is cut, and post-process the two ends separately, so as to ensure the smoothness of the cutting and the quality after cutting.
