Manual cam elastic adjusting device for circular knife machine

Abstract

The invention relates to a manual cam elastic adjusting device for a circular knife machine. The manual cam elastic adjusting device comprises a machine base, a bottom roller is mounted on the machine base, and a pressing roller is in pressure joint to the bottom roller. The manual cam elastic adjusting device further comprises pressure adjusting mechanisms, the pressure adjusting mechanisms acting on the two sides of the pressing roller are arranged on the machine base, and each pressure adjusting mechanism is composed of a spring supporting core, a rotating sleeve, a standby nut, a fixed block and a rectangular spring. The manual cam elastic adjusting device for the circular knife machine is scientific and reasonable in design, has the advantages of being convenient to operate, capable of saving time and labor, capable of improving the die cutting efficiency and reducing the rejection rate, high in adjusting accuracy and easy to implement, and has high innovativeness.

Description

technical field [0001] The invention belongs to the field of circular knife machines, and relates to a gap adjustment device, in particular to a manual cam elastic adjustment device for circular knife machines. Background technique [0002] Circular knife machine is one of the die-cutting machines, also known as rotary machine, rotary die-cutting machine, hob machine, etc., because the knife mold used is processed from a solid metal cylinder, which is similar to the flat knife mold The difference is named round knife machine, which is a common name in the die-cutting industry. It performs continuous rotary die-cutting in the form of a circular knife. It is one of the most efficient equipment in the die-cutting machine. The die-cutting products are widely used in mobile phones, computers, LCD monitors, digital cameras, LCD backlights and other fields. [0003] There are pressing rollers and bottom rollers arranged up and down on the base of the circular knife machine, and th...

AI Technical Summary

Problems solved by technology

When compounding and feeding die-cutting materials, it is necessary to adjust the fit gap between the bottom roller and the pressing roller with the change of the die-cutting process. The existing adjustment method is to realize by installing and canceling the pressing roller, or by The main disadvantages of this operation method are as follows: 1. The operation is cumbersome, time-consuming and laborious, and is not suitable for on-site production; 2. The pressing roller does not have the pressing effect on the bottom roller, which is easy Resulting in production waste; 3. The gap between the pressing roller and the bottom roller cannot be adjusted accurately, which may easily cause product size deviation; 4. The operation proficiency of the on-site workers is high, and the gap that needs to be adjusted depends entirely on experience to adjust
