Description

Technical Field

[0001] This utility model relates to the field of zipper cutting technology, and in particular to an automatic zipper cutting machine for fixed dimensional cutting. Background Technology

[0002] Zippers, widely used accessories in clothing, bags, tents, and other products, need to conform to various size and specification standards. Precision cutting ensures that the length of each zipper is accurate and meets design requirements, preventing inconsistencies in length from affecting the overall quality and appearance of the product.

[0003] Currently, many zipper manufacturers still use the relatively traditional manual cutting method. In this method, operators need to manually feed the zipper and determine the cutting position. Due to varying levels of operator skill and fatigue, it is difficult to guarantee the consistency and stability of the cut length each time, making it difficult to meet the efficiency requirements of large-scale production. Utility Model Content

[0004] Based on this, the present invention provides an automatic zipper cutting machine with a simple structure and convenient use. It utilizes the coordinated action of a cutting motor, an eccentric block, a bearing, and a lifting bracket to drive the lifting bracket to perform reciprocating lifting motion, so that the moving blade and the fixed blade form a periodic cutting action to achieve the zipper cutting to a fixed size.

[0027] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. Preferred embodiments of this utility model are shown in the drawings. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

[0028] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0030] Please see Figures 1 to 6 The zipper sizing automatic cutting machine according to one embodiment of the present utility model includes a transfer cart 10, a feeding component 20 installed on the top of the transfer cart 10, and a cutting component 30 installed on one end of the feeding component 20.

[0031] The feeding assembly 20 includes a base 21 mounted on the top of the transfer vehicle 10, a feeding plate 22 mounted on the top of the base 21, a feeding track 23 correspondingly connected to the inlet end of the feeding plate 22, a power roller 24 rotatably mounted at the outlet end of the feeding plate 22, a follower roller 25 floatingly mounted above the power roller 24, and a feeding motor 26 installed inside the base 21; the feeding motor 26 is connected to the power roller 24, and the power roller 24 and the follower roller 25 are used to convey zippers.

[0032] In this embodiment, limit strips 220 are movably installed on opposite sides of the top surface of the feeding plate 22. The length direction of the limit strips 220 is consistent with the length direction of the feeding plate 22, and the two limit strips 220 are used to guide the zipper to pass through.

[0033] In this embodiment, the feeding track 23 is provided with feeding ports 230 at opposite ends to guide the zipper through the feeding plate 22.

[0034] In this embodiment, a driven gear is coaxially connected to one end of the power roller 24, and a driving gear is coaxially connected to the rotor of the feeding motor 26. The driving gear and the driven gear are connected by a synchronous belt to realize the connection and installation between the feeding motor 26 and the power roller 24.
