A nylon zipper forming machine center line lack of material automatic stop device

Abstract

The present invention discloses an automatic centerline material deficiency shutdown apparatus for a nylon zipper molding machine. The apparatus is characterized in that one end of a sensing rod is provided with a sensing rod threading hole, and the other end of the sensing rod is positioned inside a vertical hole; a gap between two contact sheets is less than the minimum outer diameter of the sensing rod; the two contact sheets are respectively connected with both ends of a switch of an emitter; and the emitter is connected with a receiver inside a control box through a wire communication manner or a wireless communication manner. According to the present invention, the apparatus is an auxiliary apparatus installed on a nylon zipper molding machine, and adopts a wireless communication technology to achieve remote control within a certain range; the apparatus has a simple structure, and can be installed on a conventional nylon zipper molding machine to be used; assemble is convenient so as to effectively improve automation degree of equipment; generation of a large amount of wastes is avoided, and material wasting is avoided; the apparatus has good practicality, and a working state is stable; compared with the existing technology, the technology of the present invention has prominent substantive characteristics and significant advance.

Description

technical field [0001] The invention relates to the technical field of zipper forming equipment, in particular to an automatic stop device for lack of material in the center line of a nylon zipper forming machine, and in particular to its mechanical connection structure. Background technique [0002] Nylon zipper forming machines have been in the country for more than 20 years. Various equipment manufacturers and users have made many improvements, such as adding double head devices, feeding stabilization devices, and double-groove screws. However, the lack of material on the center line cannot automatically stop the machine. The main difficulty lies in the fact that there is a monofilament around the center line rotating around the center line, so that the material shortage signal on the center line cannot be transmitted to the control box to control the machine through a wired method. [0003] The operation method before adding this device is: when the operator finds that t...

Problems solved by technology

However, the lack of material on the center line cannot automatically stop the machine. The main difficulty lies in the fact that there is a monofilament rotating around the center line on the periphery of the center line, so that the signal of material shortage on the center line cannot be transmitted to the control box to control the machine by wire.

[0003] The operation method before adding this device is: when the operator finds that the center line is almost used up, he waits in front of the machine for replacement after the center line is used up. There is also the situation that the center thread is about to be used up. If it is not found in time, there will be a large amount of waste products without the center thread of the zipper. In order to avoid this phenomenon, employees often replace the center thread before it is completely used up. , which also resulted in a certain waste of material

Therefore, with the improvement of the operating level of employees, the number of machines operated is increasing, and this problem has a greater impact on efficiency and material loss.
