Automatic pressure regulating and locking structure of full-automatic high-speed precision die cutting machine

Abstract

The invention provides an automatic pressure regulating and locking structure of a full-automatic high-speed precision die cutting machine. The full-automatic high-speed precision die cutting machinecomprises a die cutting assembly and a pressure regulating assembly. The die cutting assembly comprises an upper die base and a lower die base, and a lifting seat is arranged on the lower side of thelower die base. The lifting seat is connected with the lower die base through a main eccentric shaft, and the lifting seat is driven by the main eccentric shaft to vertically ascend and descend. A lifting bottom plate is mounted on the lower side of the lifting seat through the pressure regulating assembly, and the lifting bottom plate is fixedly connected with the upper die base through a liftingguide column. The pressure regulating assembly comprises a lifting adjusting shaft, and the lifting adjusting shaft is fixed to the bottom face of the lifting seat. An external thread is arranged onthe column face of the lifting adjusting shaft, and the column face of the lifting adjusting shaft is in threaded connection with a worm wheel. The worm wheel is rotationally connected with the lifting bottom plate and is axially fixed, and the worm wheel is engaged with a worm driven by a pressure regulating driving device. Therefore, precise pressure regulation is achieved.

Description

technical field [0001] The invention belongs to the field of die-cutting machines, and in particular relates to an automatic pressure-regulating and automatic-locking structure of a fully automatic high-speed precision die-cutting machine. Background technique [0002] The working principle of the die-cutting machine is: use the template carved by steel knife, metal mold, steel wire or steel plate, apply a certain pressure through the embossing plate, and cut the printed matter or cardboard into a certain shape. The main parts of the die-cutting machine are the die-cutting platen and the press-cutting mechanism. The processed sheet is between the two, and the finishing technology of die-cutting is completed under the action of pressure. At present, the flat-press die-cutting machines on the market generally use manual pressure regulation, manual locking, manual pressure regulation, simple structure and convenient maintenance. [0003] Its disadvantages are: 1. The accuracy ...

AI Technical Summary

Problems solved by technology

[0003] Its disadvantages are: 1. The accuracy of manual pressure adjustment is poor. If the manual pressure adjustment is too much, the whole section of the material or the steel knife will be damaged or the machine will be suffocated. If the manual pressure adjustment is too small, the material will not be cut, and it will take many times Slowly adjust to achieve the effect of die-cutting. It takes a long time to adjust the machine and waste materials; 2. After the pressure is adjusted, it needs to be locked manually. When locking manually, the locking force is small and the lock is not tight. As a result, the pressure of the machine is unstable during operation. When the locking force is too large when manually locking, the locking screw will be twisted, resulting in the failure to adjust the pressure.
