Fig. 4 is a schematic structural diagram of the loading chute 210, the pushing rod 220 and the second material 20, fig. 4 (a) is an axial schematic diagram of the loading chute 210, the pushing rod 220 and the second material 20, and fig. 4 (b) is a front view of the loading chute 210, the pushing rod 220 and the second material 20 in (a) as seen along the extending direction of the loading chute 210. As shown in fig. 4, the bottom of the upper chute 210 is stepped in the width direction of the upper chute 210, so that the second material 20 can be supported obliquely on the corners of the steps when it is in the upper chute 210. Therefore, the contact area between the second material 20 and the bottom of the feeding trough 210 can be reduced, so that when one end of the pushing rod 220 pushes the second material 20 to slide in the feeding trough 210, the possibility of being blocked into a gap between the pushing rod 220 and the feeding trough 210 is reduced, and the stability of the pushing rod 220 pushing the second material 20 to move in the feeding trough 210 is improved.

Thus, by extending the slide rail 240 along the loading slot 210, the other end of the pushing rod 220 is slidably connected to the slide rail 240, so that the pushing rod 220 can be more stable when sliding along the loading slot 210, and further more stable when pushing the second material 20 to move in the loading slot 210.

As shown in fig. 2, the driving mechanism 230 includes a first motor 231, a first driving wheel 232 and a driving rod 233, wherein the first motor 231 may be in driving connection with the first driving wheel 232 by means of a belt, a chain, etc., one end of the driving rod 233 is hinged with the pushing rod 220, and the other end of the driving rod 233 is hinged with the first driving wheel 232 at an eccentric position of the first driving wheel 232. Therefore, the transmission rod 233 of the first transmission wheel 232 and the pushing rod 220 form a crank connecting rod structure, so that the rotation of the first transmission wheel 232 can be converted into the linear motion of the pushing rod 220, and the pushing rod 220 can slide along the feeding groove 210.

Specifically, the push rods 340 may be provided in plurality and evenly distributed on the drive chain 320. Thus, the push rod 340 can be driven by the driving chain 320 to extend into the feeding groove 310 from the extending opening 311, so as to push the second material 20 in the feeding groove 310 to enter the feeding groove 210 from the feeding groove 310.
