Referring to fig. 5, in the above embodiment, the positioning block 321 is provided with a base 322 and at least two movable blocks 323 adjustably mounted on the base 322, the movable blocks 323 are used for limiting the workpiece 400, the workpiece 400 may be a product with a cavity at the bottom, such as a pot lid, and may be sleeved on the movable blocks 323, the upper end of the base 322 is provided with positioning holes, the movable blocks 323 are provided with adjusting holes 324 corresponding to the positioning holes, the adjusting holes 324 may be in a shape of a long strip, and the like, and the movable blocks 323 are locked and fixed on the base 322 by passing through the adjusting holes 324 and the positioning holes. When the locking member is loosened, the movable block 323 can movably adjust the installation position of the movable block, and the movable block is locked and fixed through the locking member after being adjusted in place. Because the sizes of the positioning blocks required by different workpieces may be different, the size of the positioning block 321 can be adjusted by adjusting the position of the movable block 323 on the base 322, so that the positioning requirement of the workpiece 400 can be met.

Referring to fig. 3, in some embodiments, the loading platform 320 is provided with a falling-prevention baffle 325 at an end of the positioning block away from the lifting channel 210, and the falling-prevention baffle 325 is provided to block the workpiece 400, so that the workpiece 400 does not fall out of the loading platform 320 due to an over-speed reason when moving onto the loading platform 320, but falls back onto the positioning block 321 due to the blocking of the falling-prevention baffle 325.

Referring to fig. 1, in some embodiments, anti-bounce baffles 215 are disposed above two sides of the lifting channel 210 in the lifting direction, and the anti-bounce baffles 215 extend from the two sides of the lifting channel 210 to the middle of the lifting channel 210, so as to block a part of the space above the lifting channel 210, and prevent the workpiece 400 from bouncing upwards and dropping out of the lifting channel 210 due to an excessive distance when the lifting channel 210 is lifted.
