Platen wood cutting device for papermaking

Abstract

The invention relates to the field of papermaking equipment, and provides a pressing plate type wood cutting device for papermaking in order to solve the problem that when a tree is cut with an existing cutting device, the tree deviates from the initial position due to the fact that vibration can be generated when a cutting knife makes contact with the tree, and the tree is wrongly cut. The pressing plate type wood cutting device for papermaking comprises a cutting platform and a cutting mechanism, the cutting mechanism comprises a cutting knife and an air cylinder, a pressing plate is connected to the lower end of a piston rod of the air cylinder, the cutting knife is connected to the pressing plate, and the tree is cut with the cutting knife after being pressed with the pressing plate. The pressing plate type wood cutting device for papermaking further comprises a collecting box, a partition plate is slidably connected to the interior of the collecting box, convex blocks are arranged on the inner wall of the upper end of the collecting box, and water outlet plates are arranged on the partition plate and can be opened downwards under the action of the convex blocks; water absorption parts are arranged on the bottom face of the collecting box, an outlet is formed in the bottom of the collecting box, a filter screen is installed in the outlet, a water outlet pipe is connected to the outlet, and a driving rod is arranged on the upper end face of the partition plate and connected with the piston of the air cylinder.

Description

technical field [0001] The invention relates to the field of papermaking equipment, in particular to a press plate type wood cutting device for papermaking. Background technique [0002] Paper is the most commonly used item in our daily life. Whether we are reading, reading newspapers, writing or drawing, we have to come into contact with paper. In the production of industry, agriculture and defense industry, paper is also inseparable. The modern papermaking process can be divided into main steps such as pulping, preparation, papermaking, and processing; among them, pulping is the first step in papermaking, which refers to the process of converting wood into pulp. , and then the scraps are cooked to separate fibers, and then washed, bleached, washed and screened, concentrated or made into pulp, and finally stored for later use. [0003] Pulpwood is typically derived from four woody raw materials in logging operations in mixed forests. First of all, trees with scattered cr...

AI Technical Summary

Problems solved by technology

First of all, trees with scattered crowns have many branches in the lower part of the trunk, and these forks cannot be used for wood manufacturing, but can only be used as wood for papermaking; secondly, dead trees or trees with pests and diseases; the third is The tops and branches of trees harvested for logs; the fourth is trees too small to be logs

When cutting the first or second type of trees, because the cut trees still need to be used as logs for making other furniture or workpieces, it is necessary to ensure that the parts used as logs are used during the cutting process. It will not be damaged. Once the log part is damaged, the damaged part must be discarded during the subsequent processing of the log. In this way, the log may not meet the manufacturing size requirements, resulting in this part. The phenomenon of log waste

[0004] The reason why the log part is damaged is that when the existing cutting device cuts the tree, it usually directly cuts the tree after being placed on the cutting table. Vibration will occur when touching and cutting, and the vibration will cause the tree to deviate from the original position. At this time, the cutting knife will deviate from the original position to be cut when cutting the tree, and the tree will be cut badly. Moreover, because there will be sawdust in the whole cutting process, and some of these sawdust will fly around, causing environmental pollution, and the remaining part of the sawdust will be attached to the cutting knife, once the cutting knife is attached to the sawdust Finally, when cutting the tree, it cannot be in direct contact with the wood, not to mention reducing the cutting efficiency, and it is also prone to uneven cutting surface. When the log part is processed later, the cutting surface needs to be polished to ensure The flatness of the cutting surface is convenient for subsequent processing, which will also reduce the processing efficiency of wood
