A crossbeam 201 is fixedly installed at the bottom of the output end of the cylinder 2, and a fixed plate 4 is fixedly installed on the outer wall of the crossbeam 201. During use, when the equipment is started, the cylinder 2 pushes the crossbeam 201 and the entire rotating assembly mounted on it downwards, causing the corner trimming knife 3 to contact and cut the cardboard. After completion, the cylinder 2 retracts, ready for the next operation. The fixed plate 4 is equipped with a rotating assembly, which includes: An angle adjustment mechanism includes a drive shaft 501 and a connecting plate 5 fixedly installed on the outer wall of the drive shaft 501. The drive shaft 501 is rotatably connected between two sets of fixed plates 4 through bearings, and the end of the drive shaft 501 is inserted into the fixed plate 4. The corner trimmer 3 is fixedly installed on the connecting plate 5. The rotation of the drive shaft 501 drives the connecting plate 5 and the corner trimmer 3 to rotate, thereby adjusting the trimming angle of the corner trimmer 3. A locking mechanism, which is mounted on the fixed plate 4, is used to lock the drive shaft 501 after it has rotated to a predetermined angle.

[0019] The outer wall of the fixed plate 4 is provided with a connecting groove 401, and an adjusting knob 6 is slidably inserted into the inner wall of the connecting groove 401. The end of the adjusting knob 6 near the drive shaft 501 is provided with a slot that matches the cross block 502. The adjusting knob 6 is engaged with the cross block 502 through the slot, which is used to connect the rotation state of the adjusting knob 6 and the drive shaft 501 together. When the adjusting knob 6 moves in the direction of the drive shaft 501, it does not affect the position state of the drive shaft 501. In use, by rotating the adjusting knob 6, the drive shaft 501 is rotated, causing the connecting plate 5 to rotate accordingly, thereby causing the corner trimmer 3 fixed on the connecting plate 5 to change its angle, thus realizing the adjustment of the angle of the corner trimmer 3.

[0020] The locking mechanism includes a positioning block 604 and a positioning port 605. The positioning block 604 is trapezoidal. A slot 602 is provided on the outer wall of the adjusting knob 6, and the positioning block 604 is slidably engaged with the inner wall of the slot 602. Seven sets of positioning ports 605 are provided on the fixing plate 4 along the sliding direction of the adjusting knob 6. The angles of the seven sets of positioning ports 605 are set to 0°, 5°, 10°, 15°, 30°, 45°, and 60°, and the seven sets of positioning ports 605 correspond to seven different limiting positions, which provides seven gears for the angle adjustment of the corner trimmer 3, making it convenient for users to quickly and accurately lock the angle application. The end of the positioning block 604 is engaged in the corresponding positioning port 605. A spring strip 603 is fixedly provided on the inner wall of the slot 602, and the other end of the spring strip 603 is fixedly connected to the positioning block 604. In the natural state, the spring strip 603 pushes the positioning block 604. 4. Move away from the center of the adjusting knob 6. During use, when the adjusting knob 6 slides to the desired angle position, the positioning block 604, under the elastic force of the spring strip 603, engages in the corresponding positioning port 605, locking the adjusting knob 6 in that position, thereby locking the angle of the drive shaft 501 and the corner trimmer 3. The spring strip 603 continuously pushes the positioning block 604 away from the adjusting knob 6, promoting a tight engagement between the positioning block 604 and the positioning port 605, reducing the possibility of loosening during the trimming process. When the angle needs to be adjusted again, the operator pushes the adjusting knob 6 into the connecting groove 401, causing the positioning block 604 to be squeezed by the inner wall of the connecting groove 401, overcoming the elastic force of the spring strip 603 and retracting into the empty groove 602, so that the positioning block 604 is pulled out from the positioning port 605, and then the adjusting knob 6 is rotated to adjust the angle.

[0021] A compression spring 606 is fixedly installed on the inner wall of the connecting groove 401. In its natural state, the compression spring 606 pushes the adjusting knob 6 to move away from the fixed plate 4. When the adjusting knob 6 is rotated to the corresponding angle, the operator releases the pressed adjusting knob 6, causing the compression spring 606 to push the adjusting knob 6 to move out of the connecting groove 401. At this time, the positioning block 604 moves, thereby moving the positioning block 604 to a position aligned with the corresponding positioning port 605, so that the positioning block 604 is inserted into and locked in the corresponding positioning port 605, thereby locking the use angle of the corner trimmer 3.

[0022] A marking line 402 is fixedly installed on the outer wall of the fixed plate 4, and an indicator needle 601 for indicating the angle marking is fixedly installed on the adjustment knob 6.

[0023] Working principle: In use, the user holds the adjustment knob 6 and presses it towards the fixed plate 4 to overcome the elastic force of the compression spring 606, causing the adjustment knob 6 to move into the connecting groove 401. During this process, the inclined surface of the positioning block 604 will first contact the inner wall of the empty groove 602 and be pressed into the empty groove 602, causing the positioning block 604 to disengage from the positioning port 605. Then, the user rotates the adjustment knob 6. Because there is a slot near the drive shaft 501 that matches the cross block 502, the drive shaft 501 can be rotated, thereby causing the connecting plate 5 to rotate. The rotation drives the corner trimmer 3 to change its angle. During the adjustment process, the marking line 402 on the outer wall of the fixed plate 4 and the indicator needle 601 on the adjustment knob 6 are used to visually understand the rotation angle. When the adjustment knob 6 is rotated to the corresponding angle, the operator releases the adjustment knob 6, squeezes the spring 606 to push the adjustment knob 6 to move out of the connecting groove 401. Under the elastic force of the spring strip 603, the positioning block 604 moves to align with the corresponding positioning port 605 and is inserted and locked, locking the angle of the drive shaft 501 and the corner trimmer 3. The operation is simple and quick. After the angle is set, the equipment is started. The piston rod of cylinder 2 extends, pushing the cross frame 201 and the fixed plate 4, angle adjustment mechanism and locking mechanism to move downward as a whole. The corner trimmer 3 then descends to make a precise bevel cut on the honeycomb cardboard placed on the worktable 1. After the cut is completed, the piston rod of cylinder 2 retracts, driving the corner trimmer 3 to rise and reset, ready for the next cutting operation. This achieves fast, accurate and reliable setting of the angle of the corner trimmer 3.
