At this time, the limit spring 342 is compressed, and then the movable baffle 35 can be rotated along the damping shaft 344 to erect it and press it on one side of the material. Then the pull rod 341 is released to reset the limit spring 342. At the same time, the positioning tooth 343 limits the gear 345 again to prevent the movable baffle 35 from rotating, thereby improving the use effect of the equipment, ensuring the stability of material lifting, and preventing it from falling.

[0033] By adopting the above technical solution, when the driving screw 1 rotates to drive the movable plate 4 to rise along the guide column 2, the cleaning brush 52 at the bottom end of the movable plate 4 moves along the surface of the driving screw 1 to clean it, thereby preventing waste chips from accumulating and causing damage to the driving screw 1, thereby increasing the service life of the equipment. When the cleaning brush 52 needs to be replaced, the two-way screw 55 is rotated to separate the two sets of sliding plates 56, and then the magnet block 53 on one side of the cleaning brush 52 can be pulled out from the inside of the positioning seat 51, thereby improving the convenience of using the equipment.

[0034] Specifically, the bottom end of the sliding plate 56 is fitted with the inside of the fixing frame 54 , and a hand wheel is provided on one side of the bidirectional screw rod 55 .

[0035] By adopting the above technical solution, it is ensured that the sliding plate 56 can stably move along the inside of the fixing frame 54, thereby improving the stability of the equipment during use.

[0036] When this embodiment is in use: when the driving screw 1 rotates to drive the movable plate 4 to rise along the guide column 2, the cleaning brush 52 at the bottom end of the movable plate 4 moves along the surface of the driving screw 1 to clean it, to prevent waste accumulation from causing damage to the driving screw 1, thereby increasing the service life of the equipment. When the cleaning brush 52 needs to be replaced, the two-way screw 55 is rotated to separate the two sets of sliding plates 56, and then the magnet block 53 on one side of the cleaning brush 52 can be pulled out from the inside of the positioning seat 51, thereby improving the convenience of using the equipment.

[0039] After stacking is completed, the angle of the movable baffle 35 can be adjusted so that the movable baffle 35 can limit and block the material. The pull rod 341 is pulled to drive the positioning tooth 343 on one side of the guide plate 346 to separate from the gear 345. At this time, the limiting spring 342 is compressed, and then the movable baffle 35 can be rotated along the damping shaft 344 to erect it and press it on one side of the material. Then the pull rod 341 is released to reset the limiting spring 342. At the same time, the positioning tooth 343 limits the gear 345 again to prevent the movable baffle 35 from rotating, thereby improving the use effect of the equipment, ensuring the stability of material lifting, and preventing it from falling.

[0040] When the driving screw 1 rotates to drive the movable plate 4 to rise along the guide column 2, the cleaning brush 52 at the bottom end of the movable plate 4 moves along the surface of the driving screw 1 to clean it, so as to prevent the accumulation of waste chips and damage to the driving screw 1, thereby increasing the service life of the equipment. When the cleaning brush 52 needs to be replaced, the two-way screw 55 is rotated to separate the two sets of sliding plates 56, and then the magnet block 53 on one side of the cleaning brush 52 can be pulled out from the inside of the positioning seat 51, thereby improving the convenience of using the equipment.
