Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bag dispensing machines, in particular to an auxiliary transmission mechanism for bag dispensing machines. Background Art
[0002] Plastic bags are bags made of plastic (commonly used plastics include polypropylene, polyester, nylon, etc.) as the main raw material. They are indispensable items in people's daily lives and are often used to hold other items; bag dispensing machines, also known as bag vending machines, are usually used to automatically sell and output plastic bags.
[0003] However, when the existing bag dispensing machine is used, a transmission mechanism is usually used to transmit the plastic bags to move the plastic bags out of the bag dispensing machine. However, when the plastic bags moved out of the bag dispensing machine are pulled by external force, the transmission mechanism in the bag dispensing machine will rotate slightly, and the plastic bags that are not purchased by customers outside the transmission mechanism will leak out of the bag dispensing machine. The plastic bags are connected in a breakpoint manner, and the plastic bags that leak out of the bag dispensing machine are easily moved out of the bag dispensing machine as the external force pulls, causing losses. At the same time, the long-term rotation of the transmission mechanism will cause wear between the gears due to friction, which has a certain impact on the service life of the transmission mechanism. Therefore, an auxiliary transmission mechanism for the bag dispensing machine is provided. Utility Model Content
