[0037] Specifically, when the top plate 403 is opened, the main shaft 402 on the top plate 403 is rotated on the adjustment seat 4, and the rotation of the main shaft 402 drives the control plate 501 on the collar 5 to move. When the clamping rod 508 on the control plate 501 rotates to the opening position of the limiting groove 401, the first sliding sleeve 506 on the clamping rod 508 slides on the first positioning rod 504, so that the first sliding sleeve 506 pulls the first spring 507. When the clamping rod 508 moves to the inside of the limiting groove 401, the elastic force of the first spring 507 makes the clamping rod 508 stuck in the inside of the limiting groove 401, so as to facilitate the fixing of the top plate 403. When the top plate 403 moves to the position above the storage plate 310, according to Figure 3As shown, at this time, the movable frame 6 is in an oblique state. When the top plate 403 moves, the pin 601 first enters the inside of the C-shaped groove 610, and then the elastic force of the third spring 607 makes the third spring 607 on the second slide groove 606 snap into the inside of the C-shaped groove 610, thereby facilitating the fixing of the position of the top plate 403.

[0038] Working principle of the present invention: when it is necessary to flip the loading plate 309 to dump out the needle felt inside the storage plate 310, the telescopic cylinder 304 operates to push the adjustment plate 303 to move, and the two ends of the adjustment plate 303 are fixedly connected with the driven rod 302, and the driven rod 302 is slidably connected inside the movable groove 301, and the movement of the adjustment plate 303 drives the driven rod 302 to move, and the movement of the driven rod 302 pushes the bracket 308 on the shaft pin 307 to move through the movable groove 301, so that the middle position of the bottom surface of the loading plate 309 is rotated, so that the loading plate 309 is convenient to flip;

[0039] When pressing the needle felt inside the storage plate 310, the top plate 403 is moved to the top position of the storage plate 310, and then the turning handle 411 is turned. The turning of the turning handle 411 drives the threaded rod 409 to rotate. The threaded rod 409 is provided with positive and negative threads, and the sleeve block 408 is threadedly connected to different threads.

[0040] When the top plate 403 is opened, the main shaft 402 on the top plate 403 is rotated on the adjustment seat 4, and the rotation of the main shaft 402 drives the control plate 501 on the collar 5 to move. When the clamping rod 508 on the control plate 501 rotates to the opening position of the limiting groove 401, the first sliding sleeve 506 on the clamping rod 508 slides on the first positioning rod 504, so that the first sliding sleeve 506 can pull the first spring 507. When the clamping rod 508 moves to the inside of the limiting groove 401, the elastic force of the first spring 507 makes the clamping rod 508 stuck in the inside of the limiting groove 401, so as to facilitate the fixing of the top plate 403. When the top plate 403 moves to the position above the storage plate 310, according to Figure 3As shown, at this time, the movable frame 6 is in an oblique state. When the top plate 403 moves, the pin 601 first enters the inside of the C-shaped groove 610, and then the elastic force of the third spring 607 makes the third spring 607 on the second slide groove 606 snap into the inside of the C-shaped groove 610, thereby facilitating the fixing of the position of the top plate 403.
