Axial-position-adjustable discharging shaft of die-cutting machine

Abstract

The invention relates to an axial-position-adjustable discharging shaft of a die-cutting machine. The discharging shaft is characterized by being composed of a shaft body housing, a bearing, a spring,an adjusting nut, an adjusting screw, a spring housing, a base mandrel, a mounting base and an aluminum retaining ring, wherein the left end of the shaft body housing sequentially passes through theadjusting nut, the spring, a gasket and the bearing through the adjusting screw from left to right; the right end of the shaft body housing passes through the bearing and the gasket through the springhousing from left to right; the adjusting screw and the spring housing are in threaded connection in the shaft body housing; the spring and the base mandrel are sequentially arranged in the right endof the spring housing from inside to outside; the mounting base is mounted at the right end of the base mandrel; and the aluminum retaining ring sleeves the shaft body housing. The axial-position-adjustable discharging shaft is scientific and reasonable in structural design and has the advantages of being stable in tension, long in service life, adjustable in axial position and convenient to position, guaranteeing die cutting quality and being easy to implement.

Description

technical field [0001] The invention belongs to the field of die-cutting accessories, and relates to a discharge shaft, in particular to a discharge shaft of a die-cutting machine whose axial position can be adjusted. Background technique [0002] Die-cutting machines are mainly used in the manufacturing fields of mobile phones, digital cameras, handheld computers, LCDs, automobiles, packaging, etc. The important components on the die-cutting shaft are mainly used for self-adhesive, EVA, double-sided adhesive, electronics, and mobile phone rubber pads. , 3M glue, dust-proof materials, heat-resistant insulation materials, shock-proof products, adhesive products, backlight and other auxiliary die-cutting products. [0003] The structure and function of the existing discharge shaft are relatively single, and the adjustment in the axial direction cannot be realized, and the application is unstable and inconvenient. The material has the phenomenon of self-rotation and sliding, wh...

AI Technical Summary

Problems solved by technology

[0003] The structure and function of the existing discharge shaft are relatively single, and the adjustment of the axial position and direction cannot be realized, and the application is unstable and inconvenient. The material has the phenomenon of self-rotation and sliding, which destroys the set tension, resulting in large changes in product size, excessive Poor quality, lower product yield, lower production efficiency, etc.

In addition, the positioning of the existing die-cutting materials is realized by nylon retaining rings, but the retaining rings of this material are easy to wear after a period of application, which will bring product quality risks during the production process
