Abstract

The invention discloses a spring adjusting device which comprises a driver, a driving shaft fixed on the driver, a driving gear fixed on the driving shaft, and a fixed frame used for fixing a spring. The fixed frame is buckled on the driving gear in a clamped mode. The spring adjusting device further comprises a driven gear which can be meshed with the drive gear at a first position. The fixed frame can be disengaged from the drive gear and rotate relative to the drive gear by an angle, and therefore after the driven gear moves relative to the driving gear, the driven gear is meshed with the drive gear at a second position different from the first position. The drive shaft is controlled by the driver to rotate so as to drive the fixed frame to rotate together with the spring.

Description

technical field [0001] The invention relates to an adjusting device, in particular to an adjusting device used in an automatic vending machine for adjusting the angle of a spring. Background technique [0002] With the continuous development of modern society, people are more and more inclined to the convenient, efficient and fast pace of life. A vending machine is a physical machine that provides people with convenient and fast shopping. It is not limited by time and place, can save manpower, and facilitate transactions. There are many structures of the current automatic vending machines. Most of the vending machine containers are placed in the box body with baffles to separate the goods. A spring for driving the goods to fall is installed between the two goods. . When the goods in the vending machine are sold out, it needs to be replenished. The angle of shipment of each product is different, so the angle of the spring needs to be adjusted. However, the angles of the s...
