Efficient and stable rotary cutting machine

Abstract

The invention discloses an efficient and stable rotary cutting machine. Before the rotary cutting device begins rotary-cut operation, a first lifting driving device slides along a first horizontal guide rail in a direction away from a second clamping part. A first lower telescopic support rod and a second lower telescopic support rod slide to abut against a round wood, thereby supporting the roundwood to abut against an upper driving wheel body. A first rotating shaft is moved in the direction away from the second clamping part by driving of a first advancing and retracting motor.A first lifting frame is moved to the height of a first cutting knife corresponding to the circle center of the round wood. A worker rotates a first operation handle to perform adjustment, so that a first clamping arm clamps the round wood. A controller controls the driving of a first lifting motor, ensures that the pressure of a first main substrate on the first lifting frame before clamping the round wood is equal to the pressure after clamping, which makes the first lifting driving device slides along the first horizontal guide rail towards the direction close to the second clamping part, and makes thefirst rotating shaft moves towards the direction close to the second clamping part, so that the first cutting knife is automatically aligned with the round wood.

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 machines, in particular to a high-efficiency and stable rotary cutting machine. 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.

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
