Description

Technical Field

[0001] The utility model relates to the technical field of automatic vending machines, in particular to a rotating mechanism of a box opening device and a self-service pizza machine. Background Art

[0002] Self-service vending machines are commonly used equipment for commercial automation. They are not restricted by time and place, can save manpower and facilitate transactions. They are a new form of commercial retail, also known as 24-hour mini supermarkets. And with the changes in the market, vending machines have also appeared in various styles, including vending machines that sell pizza, etc.

[0003] The self-service pizza machine needs to place the pizza in a pizza box and then put it in a storage device for refrigeration or freezing, so as to maintain the quality of the pizza for a long time. When in use, the pizza is taken out of the storage device by the handling device and sent to the box opening device. The box opening device locates the pizza box and then opens the pizza box. The conveying mechanism sends the pizza in the pizza box to the heating device for heating. After the heating is completed, the conveying mechanism takes out the pizza, puts it back into the pizza box and sends it to the delivery port.

[0004] The existing box opening device mainly positions the pizza box through a positioning mechanism, and the positioning mechanism needs to drive the main shaft through the rotating mechanism of the box opening device to control the opening and closing of the positioning mechanism to achieve the positioning of the pizza box.

[0005] When the rotating mechanism of the existing box opening device is installed, since there is a certain gap in the driving mechanism when leaving the factory, there will also be a gap when cooperating with the main shaft. When driving the positioning member to position the box body, the box body may not be clamped in place. If the box body is clamped too tightly, it is easy to be damaged. If the box body is clamped too loosely, the box body will swing and the positioning will be inaccurate.

[0006] In view of this, it is necessary to propose a new technical solution to solve the above technical problems. Summary of the invention

[0014] In a further technical solution, the mounting plate is provided with a plurality of mounting holes, and the first end of the elastic member is connected to one of the mounting holes. This arrangement allows the first end of the elastic member to be restricted and always kept in a taut state, thereby avoiding the effect of the gap of the rotating mechanism when it leaves the factory on the clamping of the pizza box.

Through the setting of the elastic member 4, the main shaft 3 is always kept in a taut state under the action of the elastic force of the elastic member 4, that is, it is subjected to a force in one direction, inward or outward. Therefore, when the box body is positioned, the stability of the box body can be guaranteed to avoid swinging, inaccurate positioning and damage. It should be noted that when the driving mechanism 2 of the utility model drives the main shaft 3 to rotate, the force transmitted by the driving mechanism 2 is greater than the elastic force of the elastic member 4.

The two flange bearings are respectively installed in the second installation groove 34, and the position of the flange bearings is limited by the limiter 35. The arrangement of the bearing group 33 can further enhance the stability of the main shaft 3, realize the rotation of the main shaft 3, and avoid the interference of the mounting plate 1.

[0048] In a further specific embodiment, the mounting plate 1 is provided with a plurality of mounting holes 11, and the first end of the elastic member 4 is connected to one of the mounting holes 11. This arrangement allows the first end of the elastic member 4 to be restricted and always kept in a taut state, thereby avoiding the effect of the gap of the rotating mechanism when it leaves the factory on the clamping of the pizza box.
