Automatic high quality rotary cutting device

Abstract

The invention relates to an automatic high quality rotary cutting device. In a rotary cutting process, a first lifting driving device drives a first lifting rack to lift along a first guiding frame till the center of a first positioning cutter knife and the center of a log are substantially located at a same height. A user operates a first operating handle to push a first sleeve main body to movetoward the direction of the log along a thread; the first sleeve main body applies an inward pressure to a first positioning arm through a first leaning sleeve; the first positioning arm clamps the log through a pair of first leaning tongs; and finally, the log is clamped all around by means of the leaning tongs of three positioning arms. A first advancing and retreating motor drives a first advancing and retreating worm wheel to rotate through a first advancing and retreating worm; the first advancing and retreating worm wheel drives a first shaft main body to slide toward the direction of the log through a first advancing and retreating screw; a first blade is in leaning contact with the log and cuts the log rotatably to form a groove corresponding to a first cone-shaped head to be in leaning contact with a groove formed by rotatably cutting a first end cover automatically, so that an effect of automatic centering is achieved.

Description

[0001] The patent application of this invention is a divisional application of Chinese patent application number 201810312938.5. The original application number is 201810312938.5, and the application date is April 09, 2018. The name of the invention is a high-efficiency automatic centering rotary cutting machine. technical field [0002] The invention relates to the mechanical field, in particular to an automatic high-quality rotary cutting device. Background technique [0003] At present, in the field of material cutting, the existing high-precision rotary cutting machines on the market are generally large in size and complex in structure. Before using the machine, the log needs to be centered. If the centering is not accurate, intermittent veneers will be unscrewed when the rotary cutting is started. Belt or narrow veneer. The more broken veneers or narrow veneers, the more good sapwood veneers are lost, which is not conducive to continuous production. [0004] The prior ...

[0003] At present, in the field of material cutting, the existing high-precision rotary cutting machines on the market are generally large in size and complex in structure. Before using the machine, the log needs to be centered. If the centering is not accurate, intermittent veneers will be unscrewed when the rotary cutting is started. belt or narrow veneer

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
