Paper pulp molding edge trimmer

Abstract

The invention discloses a paper pulp molding edge trimmer, which comprises a bed body and a transverse moving mechanism, a longitudinal moving mechanism, a lower die holder, a pressing down mechanism and an upper die holder which are arranged on the bed body; the lower die holder and the upper die holder are matched; when being combined, the lower die holder and the upper die holder form a containing cavity together for containing a paper pulp box to be edge-trimmed; the lower die holder is fixed on the longitudinal moving mechanism and can drive the same to longitudinally move; the longitudinal moving mechanism is arranged on the transverse moving mechanism and can drive the longitudinal moving mechanism and the upper die holder to transversely move; the lower die holder is fixed on the pressing down mechanism and can drive the lower die holder to move up and down. By adopting a mechanism drive manner, the pollution hidden danger existing in hydraulic drive is fundamentally avoided; the paper pulp molding edge trimmer is simple in structure, convenient to operate, thus ensuring the edge-trimming precision and stability of the paper pulp molding edge trimmer; the production cost is reduced while the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment manufacturing, and in particular relates to a paper paddle molding trimming machine. Background technique [0002] Pulp molded products are molded in the state of pulp by using molds, which can produce complex and precise semi-finished pulp boxes, which are widely used and have good development prospects. However, the pulp box prepared by the mold will have redundant pulp parts around it, which needs to be trimmed to meet the requirements of use. [0003] At present, the existing trimming equipment for trimming the pulp box is a rotary cutter for cutting metal parts, the pressing is a mechanical hydraulic structure, and the rotation is realized by a pendulum cam. For example, the patent application in China, in which "the application number is 2013100310234, and the name is a kind of automatic paper-plastic product trimming mechanical equipment". [0004] It can be understood that w...

AI Technical Summary

Problems solved by technology

[0004] It can be understood that when the above edge trimming equipment is working, the pulp box to be trimmed needs to be fed in manually or sent in and taken out by another device. The equipment has complex structure, large volume, inaccurate positioning, high energy consumption, and volume Large size, high failure rate, poor versatility, high use cost, and high operating cost, and there is also the possibility of hydraulic oil leakage easily contaminating the pulp box
