Description

Technical Field

[0001] The utility model relates to an automatic vending machine, in particular to a pushing device of the automatic vending machine. Background Art

[0002] Chinese Patent No. ZL201920563483.4 discloses a pushing mechanism, a cargo channel and an automatic vending machine, wherein the pushing mechanism includes a motor, a screw, a guide part and a pushing part. The screw is connected to the motor through a one-way bearing; the length of the guide part extends along the length direction of the screw, and the guide part and the screw are arranged at intervals; the pushing part is connected to the screw by a threaded transmission, and the pushing part is slidably connected to the guide part, and the pushing part is used to push the goods along the length direction of the screw. The pushing mechanism is provided with a one-way bearing, so that when the goods are shipped, the motor drives the pushing part to move so that the goods are output. When replenishment is required, under the action of the one-way bearing, the power connection between the motor and the pushing part is disconnected, and the pushing part can be manually pushed to reset the pushing part.

[0003] Because the pushing unit is vertically arranged on the screw rod, the goods to be pushed are stacked front to back and arranged in front of the pushing unit, and the pushing unit moves along the front of the screw rod to push the goods to be pushed forward. Therefore, the pushing unit can only stop on the screw rod after pushing the goods. Therefore, when replenishment is needed, the power connection between the motor and the pushing unit needs to be disconnected, and then the pushing unit is manually pushed to reset the pushing unit. In this way, the goods can be replenished, which makes the replenishment process more cumbersome.

[0004] Therefore, further improvement is needed. Utility Model Content
