Paper-plastic forming machine

Through the design of linkage plates and active plates, the fast mold closing operation of the lower mold and upper mold in the paper molding machine is achieved, which solves the problem of long mold closing time caused by the slow rise of the lower mold in the prior art. Through the setting of pneumatic push rods and cleaning brushes, the cutting and cleaning efficiency of the upper mold is improved and the overall production efficiency is improved.

AI Technical Summary

Technical Problem

The existing paper molding machines need to operate slowly during the lower mold rise to prevent the pulp from spilling, resulting in a long time for upper mold and lower mold clamping and low efficiency.

Method used

By setting up the sliding of the linkage plate and the active plate to drive the upper die to slide synchronously, the linkage plate rotates to drive the driven bottom plate to slide along the outer wall of the working frame, thereby realizing the rapid mold closing operation of the lower die and the upper die, and achieving rapid mold closing by the cooperation of the pressing bar and the pressing groove; at the same time, a pneumatic push rod and cleaning brush are set to realize the unloading and cleaning operation of the upper die.

Benefits of technology

It realizes rapid mold clamping of paper pulp and efficient cutting and cleaning of molding, and improves the working efficiency and production stability of paper molding machines.

Abstract

The utility model belongs to the technical field of paper-plastic forming, and particularly relates to a paper-plastic forming machine which comprises a main body frame, the bottom end of the main body frame is fixedly connected with a paper pulp pool, the top end of the main body frame is fixedly connected with a working frame, and the top end of the working frame is fixedly connected with a hydraulic cylinder. The output end of the hydraulic cylinder is fixedly connected with a driving plate slidably connected with the outer wall of the working frame, the bottom end of the driving plate is slidably connected with an upper die, and a driving hole groove is formed in the side wall of the driving plate. The driving plate slides to drive the linkage plate to rotate through the driving hole groove, the linkage plate rotates to drive the driven bottom plate to slide relative to the driving plate along the outer wall of the working frame through the driven hole groove, the driven bottom plate slides to drive the lower die to slide synchronously, paper pulp in the paper pulp pool flows into the lower die, and the lower die and the upper die are matched through the pressing strip and the pressing groove. And rapid mold closing operation of paper pulp is realized.
