The adsorption structure 6 includes an electromagnet 61 and a magnet 62. The electromagnet 61 is fixedly installed on the lower end surface of the sliding frame 12, and the lower end of the feeding box 9 is fixedly installed with a magnet 62. The electromagnet 61 is adsorbed with the magnet 62 when power is turned on. Both sides of the upper edge of the feeding box 9 are connected to the sliding frame 12 through a clamping structure 8. The clamping structure 8 includes a clamping rod 81 and a support block 82. The clamping rod 81 is fixedly installed on the upper edge of the feeding box 9, and the support block 82 is fixedly installed on the inner side wall of the sliding frame 12. The clamping rod 81 is clamped with the support block 82, and the clamping rod 81 is located on the side of the support block 82 away from the adsorption structure 6.

[0018] Through the action of the outer frame 1, the travel trajectory of the feeding box 9 and the lifting height of the feeding box 9 are ensured. The inner wall of the feeding box 9 is an inclined bottom surface, and the side away from the discharge box 11 is higher than the other side, which is convenient for the raw materials to enter the discharge box 11. When the feeding box 9 is placed at the bottom, it is convenient for other equipment to pour sufficient raw materials into the feeding box 9.
