Rotary cutting mechanism with efficient and continuous rotary cutting function

Abstract

The invention discloses a rotary cutting mechanism with efficient and continuous rotary cutting function. In the rotary cutting process, a first lifting driving device drives a first lifting frame toascend and descend along a first guiding frame until the center of a first positioning and cutting knife and the center of the round wood are approximately located at the same height, a user operatesa first operation handle to push a first sleeve main body to move towards the round wood along threads, the first sleeve main body applies the inward pressure on a first positioning arm through a first abutting sleeve, the first positioning arm performs clamping through a first abutting gripper, finally, all the abutting grippers of the three positioning arms can carry out omni-directional clamping on the round wood, a first advancing and retreating motor drives a first advancing and retreating worm wheel to rotate through a first advancing and retracting worm, the first advancing and retreating worm wheel drives a first shaft main body to slide towards the round wood through a first advancing and retreating screw, a first blade is in abutting contact with the round wood, and performs rotary cutting on the round wood to form a groove corresponding to a first conical head, a groove part, formed by rotary cutting, of a first end cover performs automatic abutting contact, so that the 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 field of machinery, in particular to a rotary cutting mechanism for high-efficiency continuous rotary cutting. 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 produ...

[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
