Detailed Description

The invention is further illustrated with reference to the following figures and examples.

Referring to fig. 1 to 3, a conveying mechanism includes a limiting mechanism, a motor 1 and a driving fluted disc 10 connected to the motor 1, the driving fluted disc 10 is connected to a driven fluted disc 11 through an annular chain 2, the limiting mechanism is arranged at the upper end of the annular chain 2, a groove body 5 for the limiting mechanism to slide is arranged in the middle of the annular chain 2, the groove body 5 is located at the central line position of the limiting mechanism, the upper end of the limiting mechanism is connected to a pawl 6, the conveying mechanism further includes a conveying belt 8, a rack 9 matched with the pawl 6 is arranged at the lower end of the conveying belt 8, a critical point exists when the pawl 6 rotates clockwise, the critical point is that the pawl 6 cannot rotate anticlockwise when being matched with the rack 9, a stop block is arranged in the mechanism, and the explanation is not provided in the drawings, which is convenient for.

In fig. 4, the limiting mechanism includes a carrier 3, limiting plates 17 are disposed at both ends of the carrier 3, a first limiting post 12 and a limiting block 4 are disposed on the limiting plate 17, a rotary table 18 is further disposed on the limiting plate 17, a stop 16 is connected to one end of the first limiting post 12 close to the rotary table 18, the stop 16 and the limiting block 4 are both connected to the rotary table 18, a protruding block 13 adapted to the two limiting blocks 4 is disposed on the endless chain 2, a second limiting post 14 adapted to the two first limiting posts 12 is disposed at both ends of the endless chain 2, the stop 16 is further connected to a return spring 15, the rotary table 18 is rotatably connected to the limiting plate 17, a cylinder is further disposed on the rotary table 18, the stop 16 is connected to the cylinder, specifically, the limiting block 4 is connected to the first limiting post 12 by the reciprocating rotation of the rotary table 18, the movement of the protruding block 13 is controlled, so that the whole structure, and errors are effectively solved.

Further, a limit plate 17 extends from one end of the first limit post 12 away from the stopper 16. The first limiting column 12 is conveniently aligned with the second limiting column 14, the limiting block 4 protrudes to form a clamping block 41, the end portion of the clamping block 41 is in a convex arc shape, the convex block 13 is conveniently controlled to move, and the end, away from the clamping block 16, of the first limiting column 12 is in a concave arc shape, and is conveniently matched with the second limiting column 14.
