Efficient balanced rotary cutting machine for bidirectional rotary cutting

Abstract

The invention provides an efficient balanced rotary cutting machine for bidirectional rotary cutting. Before rotary cutting, a conveying part conveys round logs to a feeding part one by one, the feeding part supplies the round logs to a rotary cutting part one by one, and then a first rotary cutting mechanism and a second rotary cutting mechanism perform simultaneous rotary cutting on the round logs to realize balanced and efficient rotary cutting. Specifically, the round logs are placed above two supporting rollers, each motor drives a corresponding screw to rotate, drives each horizontal moving frame to move, drives each telescopic support rod to slide and adjusts until the two rotating rollers are in abutting contact with the round logs for positioning; during the rotary cutting process, each rotating drive motor drives a corresponding rotating roller to rotate to drive the round logs to rotate; and during the rotary cutting, each advance and retreat driving device drives a corresponding rotary cutting knife to simultaneously cut the round logs, and the contact point between each rotary cutting knife and the corresponding round log is set in a central symmetrical form centered on the round log axis, so that the round logs can be subjected to balanced rotary cutting knife pressure during the rotary cutting process, and the generated vibration and the like can be mostly counteracted.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a high-efficiency balanced rotary cutter for bidirectional rotary cutting. Background technique [0002] Existing high-precision rotary cutting machines are generally large in size and complex in structure, and log positioning is required before the machine is installed. If the positioning is not accurate, intermittent veneer strips or narrow veneer 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. [0003] 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...

Problems solved by technology

[0002] Existing high-precision rotary cutting machines are generally large in size and complex in structure, and the logs need to be positioned before the machine is installed. If the positioning 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

[0003] 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 with the top of the frame, and the lower part of the left side wall in the frame is inclined to be provided with a cylinder, and the bottom of the cylinder is hingedly connected with the left side wall in the frame, but the rotary cutter of the prior art is one-way rotary cutting, and the positioning It is not stable enough, the rotation is uneven during the rotary cutting process, the vibration amplitude of the rotary cutting is large, and the rotary cutting error is prone to occur, which reduces the precision of the rotary cutting, resulting in uneven thickness of the veneer produced by the rotary cutting and cutting edges, which in turn leads to the quality of the wood chips produced by the rotary cutting Poor, especially with intermittent waste of wood chips, increasing the economic cost of the raw material
