Zipper long chain cutting device

Abstract

The invention relates to a zipper long chain cutting device which is used for cutting a zipper long chain into strips of zippers. The zipper long chain cutting device comprises a conveying mechanism and a cutting mechanism, wherein the cutting mechanism comprises an upper cutter and a lower cutter, the conveying mechanism comprises a fabric strap clamp and an output wheel set, the fabric strap clam and the output wheel set are arranged on two sides of the cutting mechanism, and the fabric strap clamp is used for clamping and conveying the zipper long chain to the output wheel set. The zipper long chain cutting device further comprises a jacking blocking mechanism, wherein the jacking mechanism comprises a sliding block which can move up and down in a reciprocation mode and a positioning bar which can horizontally and transversely move in a reciprocation mode, a positioning hole is formed in the sliding block, the lower cutter is fixed on the sliding block, and the positioning bar is at least partially taken in the positioning hole and is connected with the side wall of the positioning hole in an abutting mode when the cutting mechanism works. The cutting mechanism can cut the zipper long chain according to a predetermined position, and thus zippers obtained through cutting have the advantage of being neat in cuts.

Description

technical field [0001] The invention relates to a zipper long chain cutting device. Background technique [0002] Existing slide fasteners can be roughly divided into closed slide fasteners and open slide fasteners, and open slide fasteners are divided into two types of single opening and double opening. Because the double-opening zipper has the advantage that it can be opened or closed arbitrarily from both ends of the zipper, therefore, the double-opening zipper is widely used in fields such as luggage. Please refer to Figure 7 , which shows a double-opening zipper long chain 50, the double-opening zipper long chain 50 includes two cloth tapes 52, and the two cloth tapes 52 are respectively provided with several sections of chain teeth 54 opposite to each other. Each segment of chain teeth 54 is spaced at equal distances to form several blank segments 56 . One end of each blank segment 56 is provided with a pair of upper stops 51 adjacent to one chain element 54 , and t...

Problems solved by technology

[0004] Yet this zipper cutting machine platform is only suitable for cutting off the long zipper chain of single opening, when utilizing this upper conveying wheel 4 and this lower conveying wheel 20 to push and convey this double-opening zipper long chain 50, due to the double-opening zipper The pull-down head 57 of the long chain 50 is easy to move on the two bottom stops 53. Therefore, in the process of conveying, the double-opening zipper long chain 50 is prone to defects such as arching and insufficient conveyance, which will result in cutting the obtained double-opening zipper. The cut is uneven
