Automatic precise rotary cutting device

Abstract

The invention provides an automatic precise rotary cutting device. According to the rotary cutting device, before the rotary cutting device starts rotary cutting work, a first lifting driving device slides in the direction far away from a second clamping part along a first horizontal guide rail, a first lower telescopic supporting rod and a second lower telescopic supporting rod slide to be in contact with a log in a top abutting mode, the log is supported to be in contact with an upper driving wheel single body in a top abutting mode, a first advancing and retreating motor drives a first rotating shaft to move in the direction away from a second clamping part, a first lifting frame moves to the position where the height of a first cutting knife corresponds to the height of the circle center of the log, working personnel rotate a first operation handle for adjustment, then a first clamping arm clamps the log, a controller controls driving of a first lifting motor, so that the pressureof a first main base plate to the first lifting frame before the round log is clamped is equal to the pressure after the round log is clamped, then the first lifting driving device slides in the direction close to the second clamping part along the first horizontal guide rail, the first rotating shaft moves in the direction close to the second clamping part, and then the first cutting knife and the log are aligned automatically.

Description

[0001] The patent application for this invention is a divisional application of Chinese patent application number 201810312931.3. The original application number is 201810312931.3, and the application date is April 09, 2018. The name of the invention is an automatic precision rotary cutting machine. technical field [0002] The invention relates to the field of rotary cutting machinery, in particular to an automatic and precise rotary cutting device. Background technique [0003] Existing high-precision rotary cutting machines are generally large in size and complex in structure, and the logs need to be centered before being put on the machine. If the centering is not accurate, intermittent veneer strips or narrow veneers will be unscrewed when the rotary cutting starts. The more broken veneers or narrow veneers, the more good sapwood veneers are lost, which is not conducive to continuous production. [0004] The prior art discloses a high-precision wood processing rotary cu...

Problems solved by technology

[0003] Existing high-precision rotary cutting machines are generally large in size and complex in structure. Before using the machine, the logs need to be centered. If the centering is not accurate, intermittent veneer strips or narrow veneers will be unscrewed when the rotary cutting is started.

The more broken veneers or narrow veneers, the more good sapwood veneers are lost, which is not conducive to continuous production

[0004] The prior art discloses a high-precision wood processing rotary cutting machine with an application number of 201621000309.1, which includes a rear side plate, a frame, a cylinder, a first inclined plate, a strut, an abutment, a first sliding sleeve, and a first movable Rods, rollers, first springs, buttons, support rollers, etc.; the bottom of the front side of the rear side plate is provided with a frame, and the top of the frame is sequentially provided with a first slant plate, a support rod and an abutment from left to right, and the first slant plate The bottom end is hingedly connected to the top of the frame, and the lower part of the left wall in the frame is inclined to be provided with a cylinder, and the bottom of the cylinder is hingedly connected to the left wall inside the frame, but this prior art lacks a centering function and cannot automatically move logs. Alignment may lead to poor quality of wood chips produced by rotary cutting, especially intermittent waste of wood chips, which increases the economic cost of raw materials
