Intelligent accurate rotary-cut equipment

Abstract

The invention provides intelligent accurate rotary-cut equipment. In the rotary-cut process, a first lifting driving device drives a first lifting frame to ascend and descend along a first guiding frame till the center of a first positioning cutting knife and the center of a round log are roughly at the same height; a user operates a first operating handle to push a first sleeve body to move alonga thread towards the round log; the first sleeve body applies the inward pressure to first positioning arms through first jacking sleeves, the first positioning arms conduct clamping through first jacking hand grabs, and finally the round log is clamped in an all-dimensional mode through all the jacking hand grabs of the three positioning arms; a first advance and retreat motor drives a first advance and retreat worm wheel to rotate through a first advance and retreat worm; the first advance and retreat worm wheel drives a first shaft body to slide towards the round log through a first advance and retreat screw; and a first blade makes contact with the round log in a jacking mode to conduct rotary-cut on the round log to form a groove corresponding to a first conical head, grooves formedby rotary-cut of a first end cover partially automatically make contact in a jacking mode, and thus 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 an intelligent and precise 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 pri...

[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
