Description

Technical Field

[0001] The invention relates to the technical field of rotary cutters, and in particular to a rotary cutter with adjustable knife gap size and drop. Background Art

[0002] The rotary cutter is a device that produces skin boards by cutting logs in a circle. Such skin boards are mostly used to produce plywood, joinery boards and other man-made board veneers. At present, when it is necessary to cut skin boards of different thicknesses in a circle, workers are generally required to manually adjust the gap between the rotary cutter and the single-row roller, which is relatively cumbersome.

[0003] In order to realize the automatic adjustment of the knife gap, the applicant has improved the structure of the rotary cutter; the design principle of the improved rotary cutter is briefly described as follows: a support bent plate is hinged on both sides of the knife table, a transmission bearing is rotatably connected to the end of the support bent plate, and a first cam that can actively rotate is arranged under the transmission bearing; the transmission bearing is in rolling contact with the first cam; a single row of rollers is fixed on the support bent plate;

[0004] When the first cam is driven to rotate, the rotation of the first cam can cause the support curved plate to rotate and change along with the wheel diameter of the first cam. The rotation change of the support curved plate will adjust the height of the single-row roller to change the size of the knife gap, thereby automatically adjusting the size of the knife gap and the height difference between the rotary cutter and the log surface. For a specific schematic diagram, please refer to Figure 3 .

[0005] The applicant discovered the following technical problems when using the above-mentioned peeling machine for actual operation:

[0006] (1) Because one side of the support bent plate is hinged to the knife platform to form a lever principle, but the other side of the support bent plate is not fixed, when encountering the impact of hard wood, it will cause the support bent plate to vibrate, and the vibration will affect the stability of the knife seam, and thus the quality of the ring cutting;

[0007] (2) If the support bend is subjected to a large external force (such as the cutting resistance of hardwood), it may cause one side of the support bend to flip over, and may even cause the equipment to shut down or be damaged; flipping will not only affect the normal operation of the equipment, but may also cause safety hazards;

[0008] (3) However, how to fix the structure on the other side of the supporting curved plate and drive the first cam to rotate and adjust the knife gap? Because the supporting curved plate cannot rotate and change with the wheel diameter of the first cam, the knife gap size and drop cannot be adjusted.

[0009] Therefore, how to solve the above technical problems is a technical problem that those skilled in the art need to solve.

[0010] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art.

[0073] In this embodiment, the dynamic position stabilization unit includes: a fixed shaft 172, a fixed shaft sleeve 171 and a connecting rod compensation module 180;

[0077] The short cylindrical body 187 is provided with a plurality of radial holes 187a, and bolts are inserted into the radial holes 187a to lock the short cylindrical body 187 on the first transmission shaft 165; however, since the long cylindrical body 181 is coaxially rotatably connected with the short cylindrical body 187, the long cylindrical body 181 can rotate freely on the first transmission shaft 165;

[0078] The long cylindrical body 181 is provided with a cam activity cavity 181b coaxially arranged with the shaft hole 181a, and the second cam 183 is arranged in the cam activity cavity 181b and fixedly connected with the first transmission shaft 165; the second cam 183 is the same in size and shape as the first cam 163; at the same time, the second cam 183 and the first cam 163 are also installed at the same angle on the first transmission shaft 165; thus, the synchronization of the movement and rotation of the first cam 163 and the second cam 183 can be ensured;

[0079] The side cone 182 is fixed to the side wall of the long cylindrical body 181. The side cone 182 is provided with a cylindrical cavity 182a along its length direction, which is connected with the cam active cavity 181b on the long cylindrical body 181. The cavity wall of the cylindrical cavity 182a is provided with an internal thread.

[0080] The bolt 184 is threadedly locked on the internal thread of the cylindrical cavity 182a; a through hole is provided on the bolt 184 along its axial direction; and the connecting rod 185 is movably inserted in the through hole of the bolt 184;

[0082] The spring 186 is arranged in the cylindrical cavity 182a and is sleeved on the connecting rod 185; the lower end of the spring 186 is fixedly connected to the connecting rod 185, and the upper end of the spring 186 is fixedly connected to the tail of the bolt 184.

[0083] In this embodiment, the short cylindrical body 187 is also provided with an annular groove 187b coaxially arranged with the axial hole 181a, and the diameter of the annular groove 187b is larger than the diameter of the axial hole 181a; the end of the long cylindrical body 181 is provided with an annular limit plate 181b whose size is matched with the annular groove 187b, and the annular limit plate 181b is rotatably connected in the annular groove 187b.

[0084] The working method of a rotary cutting machine with adjustable knife gap size and drop provided in this embodiment is specifically as follows:

[0085] 1. Control the second motor 166 to work, drive the first transmission shaft 165 and the first cam 163 to rotate; the rotation of the first cam 163 can cause the supporting curved plate 161 to rotate and change along with the wheel diameter of the first cam 163, thereby realizing the adjustment of the knife gap size;

[0086] 2. When the second motor 166 is working, the second cam 183 will rotate synchronously with the first cam 163, and the connecting rod 185 in the connecting rod compensation module 180 can move in length in the cylindrical cavity 182a of the side cone 182 as the wheel diameter at the contact position with the second cam 183 changes. The length change of the connecting rod 185 extending outside the cylindrical cavity 182a can be used to compensate for the change in the distance between the first transmission shaft 165 and the supporting bent plate 161 caused by the rotation change of the first cam 163;

[0087] 3. Because the second cam 183 and the first cam 163 have the same size, shape and installation angle on the first transmission shaft 165, this ensures that the length change of the connecting rod 185 is substantially equal to the change in the distance between the first transmission shaft 165 and the supporting curved plate 161, which not only solves the technical problem that the other side of the supporting curved plate cannot be structurally fixed, but also ensures that the supporting curved plate can rotate and change with the wheel diameter of the first cam;

[0088] 4. At the same time, because the connecting rod 185 is connected in the cylindrical cavity 182a by the spring 186, it not only improves the convenience of the connecting rod 185 to be telescopic in the cylindrical cavity 182a, but also plays a certain vibration reduction role.

[0109] 5.
