[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] This invention prevents the log from warping due to excessive cutting force by using a pressing panel and the elastic force of a pressing spring. The preload of the pressing spring reduces the pressure when processing logs with smaller diameters to avoid wood indentations. When processing logs with larger diameters, the pressure is increased to ensure stable cutting and prevent the log from warping, thereby meeting the diversified production needs of wood processing plants. The logs are squeezed by the anti-rotation frame to prevent them from rotating during cutting. Preventing the logs from rotating can ensure that the cutting path is accurate and controllable, avoid incision deviation caused by wood rotation, and prevent the logs from rotating to avoid dangerous conditions such as splashing and cracking caused by log loss of control, thereby significantly improving the safety of wood processing operations.

[0016] This invention ensures that the cutting size remains constant during the cutting operation by moving the multi-tooth plate downward to contact the fixed-size plate and limit the fixed-size plate. The fixed-size plate is fixed in a preset position through tooth-like engagement, thereby ensuring that the cutting reference is always stable and effectively avoiding waste and rework of logs due to size deviation.

[0017] (3) This invention adjusts the cutting size by pushing the cut-to-length plate to move horizontally forward. The combination of the cut-to-length plate and the bidirectional telescopic elastic rod can adapt to different cutting sizes by adjusting the position of the cut-to-length plate, thereby enhancing the versatility of the equipment and its adaptability to application scenarios, and reducing repeated investment due to the single function of the equipment.

[0018] (4) In this invention, the speed of adjusting the cutting size is limited because the combination rod can only be moved slowly to the side. The operator can gradually test and determine the optimal cutting size by slowly moving the combination rod, thereby ensuring that the cutting path is highly consistent with the predetermined path. If any abnormality occurs during the slow adjustment process, the operation can be stopped in time, further ensuring the safety of personnel and the stable operation of the equipment.

[0019] (5) This invention drives the disassembly plate forward by moving the disassembly frame forward. When the disassembly frame drives the disassembly plate forward, the logs can be actively loosened, thereby destroying the adsorption force between the logs and the rotating cutting tool, thereby preventing excessive friction from causing difficulty in unloading the logs or the rotating cutting tool from getting stuck.

The anti-rotation spring 9 is arranged between the anti-rotation frame 8 and the annular frame 3. The anti-rotation frame 8 moves downward to squeeze the anti-rotation spring 9. The anti-rotation spring 9 is squeezed by the anti-rotation frame 8 to produce deformation and accumulate force. After the anti-rotation frame 8 is out of contact with the pressing panel 5, the anti-rotation spring 9 can drive the anti-rotation frame 8 to reset. The placement groove 11 is opened on the inner wall of the cutting table 1, and the arc rod 12 is fixedly installed at the bottom of the cutting board 4. Preventing the log from rotating can ensure that the cutting path is accurate and controllable, avoid incision deviation caused by the rotation of the wood, and preventing the log from rotating can avoid dangerous conditions such as splashing and cracking caused by the loss of control of the log, thereby significantly improving the safety of wood processing operations.

[0032] The anti-rotation frame 8 is in contact with the inner wall of the annular frame 3, and the annular frame 3 is used to place the logs. The pressing panel 5 is used to prevent the logs from warping at the cut part. The pressing panel 5 cooperates with the elastic force of the pressing spring 7 to prevent the logs from warping due to excessive cutting force. The pre-tightening force of the pressing spring 7 can reduce the pressure to avoid log indentation when processing logs with smaller diameters. When processing logs with larger diameters, the pressure is increased to ensure stable cutting and prevent logs from warping, thereby meeting the diversified production needs of wood processing plants.

[0033] During operation, the pushing module pushes the log to be cut into the inside of the annular frame 3. After the log is pushed into the inside of the annular frame 3, a linear motor is provided on the top of the cutting frame 2 and the output end of the linear motor is fixedly connected to the cutting plate 4. The linear motor drives the cutting plate 4 to move downward, and the downward movement of the cutting plate 4 drives the rotating cutting tool to move downward.

The pressing panel 5 The reaction force of the squeezed log moves upward, and the pressing panel 5 moves upward to pull the pressing spring 7. The pressing spring 7 is deformed and stores force due to the pulling of the pressing panel 5, and the pressing panel 5 cooperates with the elastic force of the pressing spring 7 to prevent the log from tilting due to excessive cutting force. At the same time, the pressing panel 5 moves downward to contact the anti-rotation frame 8 and squeeze the anti-rotation frame 8. The anti-rotation frame 8 moves downward due to the squeezing of the pressing panel 5. The anti-rotation frame 8 moves downward and contacts the log inside the annular frame 3 and applies pressure to the log. The log is squeezed by the anti-rotation frame 8 to prevent the log from rotating during cutting. Example 2

The combination of the sizing plate 131 and the bidirectional telescopic elastic rod 132 can adapt to different cutting sizes by adjusting the position of the sizing plate 131, thereby enhancing the versatility and adaptability of the equipment to application scenarios and reducing repeated investment due to the single function of the equipment.

[0035] The distance adjustment component also includes a multi-tooth plate 136 and a movable groove 137. The multi-tooth plate 136 is fixedly mounted on the top of the inner wall of the limit frame 135. The movable groove 137 is opened on the front side of the fixed length plate 131. The multi-tooth plate 136 moves downward to drive the limit frame 135 to move downward.

[0036] The bidirectional telescopic elastic rod 132 conflicts with the inner wall of the sizing groove 133, and a spring 1 is provided between the limit frame 135 and the cutting table 1. The limit frame 135 moves downward to squeeze the spring 1. The spring 1 is squeezed by the limit frame 135 to produce deformation and accumulate force. After the limit frame 135 is out of contact with the arc rod 12, the limit frame 135 can be driven by the spring 1 to restore the initial position. The moving groove 137 is used to prevent the sizing plate 131 from getting stuck with the limit frame 135. The multi-tooth plate 136 moves downward to contact the sizing plate 131 and limit the sizing plate 131. The sizing plate 131 is fixed in the preset position through tooth-like engagement, thereby ensuring that the cutting reference is always stable and effectively avoiding waste and rework of logs due to size deviation.

[0037] The loosening assembly includes a disassembly plate 141, a disassembly frame 142, a disassembly spring 143, a loosening plate 144 and a combination rod 145. The disassembly frame 142 slides through the front and rear walls of the fixed-size plate 131. The disassembly plate 141 is fixedly installed on the rear side of the disassembly frame 142. The disassembly spring 143 is arranged between the disassembly frame 142 and the fixed-size plate 131. The loosening plate 144 is slidably installed on the front side of the fixed-size plate 131. The combination rod 145 is slidably installed on the inner wall of the placement groove 11. The disassembly frame 142 can be supported by the disassembly spring 143. The operator can gradually test and determine the optimal cutting size by slowly moving the combination rod 145, thereby ensuring that the cutting path is highly consistent with the predetermined path.

[0038] The loosening component also includes a combination cylinder 146 and a friction long piece 147. The combination cylinder 146 is fixedly installed on the inner wall of the mounting groove 11. The friction long piece 147 slides through the circumferential surface of the combination cylinder 146. The combination rod 145 moves forward to contact the friction long piece 147 and squeeze the friction long piece 147. If any abnormality occurs during the slow adjustment process, the operation can be stopped in time to further ensure the safety of personnel and stable operation of equipment.

[0039] A second spring is provided between the combination rod 145 and the placement groove 11, and the combination rod 145 can be supported by the second spring. The combination rod 145 contacts the inner wall of the combination cylinder 146, and a third spring is provided between the combination cylinder 146 and the friction long plate 147, and the friction long plate 147 can be supported by the third spring. The disassembly frame 142 moves forward under the elastic force of the disassembly spring 143, and the disassembly frame 142 moves forward to drive the disassembly plate 141 to move forward. When the disassembly frame 142 drives the disassembly plate 141 to move forward, it can actively loosen the log, thereby destroying the adsorption force between the log and the rotating cutting tool, thereby preventing excessive friction from causing difficulty in log unloading or the rotating cutting tool from getting stuck.

[0040] During operation, the cutting plate 4 moves downward, driving the arc rod 12 to move downward. The arc rod 12 moves downward and contacts the multi-tooth plate 136 and squeezes the multi-tooth plate 136. The multi-tooth plate 136 moves downward under the squeezing of the arc rod 12. The multi-tooth plate 136 moves downward, driving the limit frame 135 to move downward. The multi-tooth plate 136 moves downward and contacts the fixed-length plate 131 and limits the fixed-length plate 131, thereby ensuring that the cutting size remains constant during the cutting operation. The cutting size of the log needs to be adjusted. When adjusting, manually push the left and right ends of the bidirectional telescopic elastic rod 132 to retract toward the middle, and the left and right ends of the bidirectional telescopic elastic rod 132 retract toward the middle to break away from the contact with the sizing groove 133 and release the limit on the sizing plate 131. After the limit of the sizing plate 131 is released, manually push the sizing plate 131 to move horizontally forward to adjust the cutting size. At the same time, the sizing plate 131 moves forward to pull the sizing spring 134. The sizing spring 134 is deformed by the pull of the sizing plate 131 and accumulates force.

[0041] The fixed length plate 131 moves forward so that the moving groove 137 contacts the combination rod 145 and squeezes the combination rod 145. The combination rod 145 is squeezed and moves forward. The combination rod 145 moves forward to pull the spring 2. The spring 2 is pulled by the combination rod 145 to deform and store force. At the same time, the combination rod 145 moves forward to contact the friction long piece 147 and squeeze the friction long piece 147. The friction long piece 147 is squeezed by the combination rod 145 and slowly deforms. The slow deformation of the friction long piece 147 makes the combination rod 145 move slowly to the side. The combination rod 145 can only move slowly to the side. The lateral movement limits the speed of adjusting the cutting size. If the rotating cutting tool is stuck between the logs due to excessive friction, the loosening plate 144 is manually pushed downward. The loosening plate 144 moves downward to break away from the contact with the disassembly frame 142 and release the limit on the disassembly frame 142. After the limit of the disassembly frame 142 is released, the disassembly frame 142 moves forward under the elastic force of the disassembly spring 143. The forward movement of the disassembly frame 142 drives the disassembly plate 141 to move forward. The forward movement of the disassembly plate 141 loosens the logs to prevent excessive friction from causing difficulty in unloading the logs or the rotary cutting tool from getting stuck.
