AI Technical Summary
During the rotary cutting process, the existing rotary cutting machine single-plate equipment needs to adjust the initial height of the angle fine-tuning mechanism due to the change in the contact position between the single drive roller and the wood. However, due to the direct screw-on being screwed on the rotary cutting machine, the height adjustment is difficult, resulting in poor molding quality.
A single-roll beam lifting and adjustment structure of a rotary cutting machine is designed, including a machine base, a single-roll beam mechanism, a double-roll beam mechanism, an angle fine-adjustment mechanism and a lifting and adjustment structure. By installing the lifting adjustment structure on the base, the height adjustment of the angle fine-tuning mechanism is achieved by using the threaded ends of the adjustment seat and the connecting bolts.
By adjusting the height of the angle fine-tuning mechanism by adjusting the lifting and lowering structure, the problem of time-consuming and labor-intensive manual adjustment in the prior art is solved, the overall debugging and maintenance speed of the equipment is improved, and the forming quality is improved.

Abstract
Description
Technical Field
[0001] The utility model relates to a lifting and adjusting structure of a single roller beam of a rotary cutting machine. Background Art
[0002] At present, the equipment for producing plywood veneer in my country is completed by rotary cutting machines with card shaft and rotary cutting machines without card shaft. The working principle of the shaftless peeling machine is that three drive rollers (double drive rollers and single drive roller) clamp the wood and drive the wood to rotate on the center line of the double drive rollers. The double drive roller moves toward the blade direction to squeeze the wood (that is, moves toward the single drive roller direction) while driving the wood, and the blade cuts the wood into veneers. During the peeling process, the diameter of the wood gradually decreases, and the contact position between the single drive roller and the wood will change. Therefore, it is necessary to fine-tune the angle of its contour surface through the linked angle fine-tuning mechanism, thereby achieving fine-tuning of the working angle of the single drive roller, and keeping the single drive roller change to change the gap with the peeling blade. However, in actual use, it is necessary to adjust the initial height of the angle fine-tuning mechanism as a whole in order to achieve the most suitable initial single drive roller working angle. At the same time, due to the height difference between the left and right angle fine-tuning mechanisms, there will be a height difference between the left and right ends of the blade mechanism on the single roller beam, which will lead to poor molding quality. Therefore, it is necessary to manually adjust the height of the angle fine-tuning mechanism, but since the existing angle fine-tuning mechanism is directly screwed on the peeling machine, it is difficult to adjust the height.

When in use, the height of the angle fine-adjustment mechanism is adjusted by the lifting and adjustment structure, thereby solving the problem of difficulty in adjusting the height of the existing angle fine-adjustment mechanism of the peeling machine.
[0023] In this embodiment, in order to adjust the height of the angle fine-tuning mechanism through the lifting and adjusting structure, a mounting groove 6 is provided on the end of the machine base corresponding to the lifting and adjusting structure, and the lifting and adjusting structure includes an adjusting seat 7, and the adjusting seat is vertically slid on the side wall of the mounting groove.
