A sequential production zipper I-code assembly machine

Abstract

The invention provides a zipper I-code assembly machine for sequential production, which includes a frame, a sub-link bar, a feeding stamping seat, a drawstring mechanism and a control unit. When the teeth are empty, the control unit controls the motor of the pull belt mechanism to stop rotating, the entrainment mechanism clamps the chain belt, and at the same time divides the chain bar and separates the chain, and feeds the material on the stamping seat so that the I-shaped code is located at the empty section of the chain teeth, and the belt loosening mechanism Roll back to loosen the originally tensioned chain belt, and the entrainment mechanism drags the chain belt under the action of the push belt mechanism until the end chain teeth of the chain element section on the front side of the chain element vacant section collide with the I-shaped code, and then the material is stamped The seat is buckled and pressed with an I-shaped code. In the present invention, when the upper end of the zipper is fed forward, the I-shaped code can be stably and accurately fixed at the lower end, which is the same as the direction of the next production equipment. The process is continuous and the production efficiency is high.

Description

technical field [0001] The invention relates to the technical field of zipper manufacturing, in particular to a sequential production zipper I-code assembly machine. Background technique [0002] In the zipper production process, the chain belts are usually tens to hundreds of meters long. After the chain teeth of a chain belt are laid out, the teeth will be extracted according to the length of the finished zipper, so that the chain teeth without chain teeth appear at equal intervals on the chain belt. Empty section, between the two chain teeth vacant sections is the chain element section of the finished zipper, the upper and lower ends of the chain element section will be installed with upper stop and I-shaped code, and the I-shaped code must be installed close to the end chain teeth of the chain element section. The existing I-code assembly machines all use the conveying method that the bottom end of the zipper is at the front. For example, the metal chain is the way of fe...

Problems solved by technology

Since this traditional I-code assembly machine installs the I-code on the front end of each chain element section, the bottom end of the zipper is moved forward, which is opposite to the input direction of the chain belt of the next production equipment. In the next production equipment, it must The zipper must be turned around and input, so only the length of one roll of chain belt can only be turned around to enter the next production link, which seriously affects the production continuity of subsequent processing and low production efficiency.

In addition, due to the unavoidable errors in the sizing and arranging process of the zipper, and the stretchability of the cloth tape, the length of the space section of the chain element is different, and it is difficult to accurately locate the position of the I-shaped code, resulting in the I-shaped code cannot be aligned with the end of the chain tooth. cling to
