Wood peeling and cutting equipment

Abstract

The invention discloses wood skinning and plate cutting equipment. The wood skinning and plate cutting equipment comprises a pretreatment device, a skinning device and a plate cutting device. The pretreatment device comprises a box body and a high-pressure pump communicating with the box body, a cavity is formed in the box body, the cavity is divided by a supporting plate into an upper layer and alower layer, a first filter hole is formed in the supporting plate, a filter box is further arranged in the cavity, and the high-pressure pump pumps air into the cavity. The skinning device comprisesa cylinder, blades arranged on the inner wall of the cylinder and a drive unit driving a log to rotate, the cylinder comprises a left half cylinder and a right half cylinder, the top of the left halfcylinder and the top of the right half cylinder are hinged so as to achieve free opening and closing of the cylinder, first elastic assemblies are arranged on the side of the left half cylinder and the side of the right half cylinder correspondingly so as to support opening and closing of the cylinder, and a discharging opening is further formed in the bottom of the cylinder so as to discharge wood skins. Skin scraping nails are further arranged on the inner wall of the cylinder, and the skin scraping nails and the blades are connected with the inner wall of the cylinder through pressure adjusting mechanisms. The plate cutting device comprises second elastic assemblies used for supporting and fixing the log and a rotary cutting knife attached to the surface of the log for rotary cutting.

Description

technical field [0001] The invention relates to the technical field of wood production and processing, more specifically, the invention relates to wood peeling and board cutting equipment. Background technique [0002] The production and processing of wood coils generally need to go through steps such as log peeling and log rotary cutting to form thin boards. The existing log peeling machines usually use a cylinder to wrap the log, fix a peeling knife on the inner wall of the cylinder, and set a driving device to drive the log relative to each other. The cylinder rotates and the paring knives scrape off the skin to complete the peeling. These traditional log peeling machines have the following disadvantages: since the peeling knife is fixed on the inner wall of the cylinder, when encountering a log with a certain curvature, some of the peeling knives stab into the log hard, which constitutes excessive damage to the inside of the log. Some paring knives cannot reach the surf...

AI Technical Summary

Problems solved by technology

These traditional log peeling machines have the following disadvantages: since the peeling knife is fixed on the inner wall of the cylinder, when encountering a log with a certain curvature, some of the peeling knives stab into the log hard, which constitutes excessive damage to the inside of the log. Some paring knives do not touch the surface of the log and cannot be peeled

This resulted in some badly damaged pared logs and some not fully peeled

[0003] The log rotary cutting machine usually drives the log to rotate, and a veneer cutter is set on the surface of the log to saw the log to form a veneer. This method of rotary cutting is likely to cause a large amount of wood loss, and the efficiency is not high.
