Door opening link gear of automatic vending machine

Abstract

The invention discloses a door opening link gear of an automatic vending machine, which comprises a storage cabin, a moveable drawer, a cabin door, a link gear and front and back driving devices; the storage cabin is used as a cargo storage space, and the inner part is provided with the moveable drawer; the moveable drawer can moveably arranged at the bottom part of the storage cabin forwards and backwards, and cargo can be placed in the inner part; the cabin door is arranged at a cabin opening of the storage cabin to open and close the cabin opening; the link gear is connected with the front and back driving devices, the cabin door and the moveable drawer; the moveable drawer is extended out and contracted through opening and closing the cabin door; the and front and back driving devices can drive the cabin door to open and close and the moveable drawer to stretch through the link gear. After applying the technical scheme, the cargo capacity of the automatic vending machine is more, the use is more convenient, and the use safety is higher; the cargo storage risk is higher; the door opening link gear is energy-saving and environment-friendly, longer in service life, more reasonable in structural design, lower in manufacturing, using and maintaining costs, and better in economic benefit.

Description

technical field [0001] The invention belongs to the technical field of automatic vending equipment, and specifically relates to a door-opening linkage mechanism of a self-service vending machine. Background technique [0002] Self-service vending machine is a common equipment for commercial automation. It is not limited by time and place. It can save manpower and facilitate transactions. It is a new form of commercial retail and is also known as a 24-hour micro supermarket. In developed countries, the use of self-service vending machines has become an indispensable part of people's daily life. A considerable part of the goods are sold by self-service vending machines. Operate on the display screen of the vending machine, enter the product number and purchase quantity, and input After the coin or credit card is swiped, the goods will come out from the pick-up port. In my country, although beverage self-service vending machines have been used in large quantities, the per capi...

Problems solved by technology

After quite a period of practical application and customer feedback, some problems were also found: with this design, all the goods in the warehouse in the same equipment must be transferred from the pick-up lifting platform to the transition platform when they are sold, and then from the Take out the goods from the same pick-up port, so the structural design is more complicated, the production cost is high, the internal operation of the equipment is complicated, the waiting time for picking up the goods is longer, the failure rate is higher, and the use and maintenance costs increase

Compared with the original self-service vending machine structure, this design simplifies a lot, but through model tests and demonstrations, it is found that it will bring the following problems: 1. The self-service vending machine is generally used to sell fast food, and the square lunch box is used. The design of the arc-shaped telescopic warehouse door, when closed, the space in front of it is an irregular arc, which cannot be used effectively; when opened, the arc-shaped warehouse door shrinks to the top of the storage warehouse, occupying a certain space in the upper part of the storage warehouse Therefore, the volume of the lunch box is limited in length and height; 2. The transmission mode of the rack and pinion has high friction and noise, high maintenance cost, short service life, high failure rate and poor stability; 3. It is difficult to ensure the sealing between the arc-shaped warehouse door and the storage warehouse, and the heat inside the storage warehouse is easy to overflow, resulting in a decrease in the heat preservation performance of the food and an increase in energy consumption; 4. Low safety, and sharp instruments are easy to fall from the Inserting and prying open the warehouse door in the gap between the arc-shaped warehouse door and the storage warehouse, resulting in the theft of goods; 5. Due to the need for food insulation, there is a heating device inside the equipment, and the metal parts inside the storage warehouse (such as: The internal side wall, top wall and bottom wall) have high temperatures; after the warehouse door is opened, when picking up the goods, people must reach into the storage warehouse to take the lunch box, and it is easy to burn when the hands touch the internal metal parts; 6. This design requires that the height of the storage warehouse should not be too high, at most level with the line of sight of people. The internal goods cannot be taken out smoothly, so the number of layers (quantity) of the storage warehouse is limited
