Description

Technical Field

[0001] This utility model relates to the field of vending machine technology, specifically to a microwave heating box drive mechanism for vending machines. Background Technology

[0002] Vending machines are commonly used equipment in commercial automation. They are not limited by time or location, saving manpower and facilitating transactions. Vending machines are a brand-new form of commercial retail that can automatically dispense goods based on the inserted coins, and are also known as 24-hour mini-supermarkets.

[0003] Vending machines typically include a dispensing compartment for loading goods. When dispensing, a goods ejection mechanism in the dispensing compartment pushes the goods out of the compartment. However, existing goods ejection mechanisms are complex, costly, and unstable. Sometimes, due to insufficient force, the goods cannot be easily ejected from the dispensing compartment, resulting in the goods getting stuck at the dispensing outlet. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology. The microwave heating box drive mechanism of the automatic vending machine has a simple structure and high stability, which can prevent goods from getting stuck at the dispensing port of the dispensing warehouse.

[0005] The technical solution of this utility model is as follows:

[0006] A microwave heating box drive mechanism for an automatic vending machine includes a dispensing compartment, a receiving plate, a dispensing door, and a goods ejection structure. The receiving plate and the goods ejection structure are disposed in the dispensing compartment. One end of the dispensing compartment has a dispensing port. The upper side of the dispensing door is rotatably connected to the dispensing port of the dispensing compartment. Goods are received from the vending machine's shelf through the receiving plate. The goods on the receiving plate are ejected from the dispensing door under the action of the goods ejection structure.

[0007] The cargo ejection structure includes a push block, a movable frame, a first linear guide rail, a second linear guide rail, a first ball screw, a second ball screw, a belt gear assembly, and a servo motor. The first and second linear guide rails are arranged opposite each other on both sides of the cargo receiving plate. The first ball screw, the second ball screw, the belt gear assembly, and the servo motor are arranged below the cargo receiving plate. One end of the first and second ball screws is connected to the driving gear and driven gear of the belt gear assembly, respectively. The other ends of the first and second ball screws are rotatably connected to the cargo discharge compartment. The motor shaft of the servo motor is connected to the driving gear of the belt gear assembly. The push block is slidably connected to the first and second linear guide rails through the movable frame and faces the cargo discharge door. Both ends of the movable frame are connected to the ball nuts of the first and second ball screws, respectively.

[0008] Furthermore, an upper magnetron assembly and a lower magnetron assembly are respectively provided on the upper and lower parts of the loading plate on the loading warehouse.

[0009] Furthermore, a servo drive switch assembly is provided on the shipping compartment, and the servo drive switch assembly is connected to the shipping door drive.

[0010] Furthermore, an oil fume hood is provided above the cargo receiving plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The cargo ejection structure of this utility model includes a push block, a movable frame, a first linear guide rail, a second linear guide rail, a first ball screw, a second ball screw, a belt gear assembly, and a servo motor. The first and second linear guide rails are arranged opposite each other on both sides of the cargo receiving plate. The first ball screw, the second ball screw, the belt gear assembly, and the servo motor are arranged below the cargo receiving plate. One end of the first and second ball screws is connected to the driving gear and the driven gear of the belt gear assembly, respectively. The other ends of the first and second ball screws are rotatably connected to the cargo discharge compartment, respectively. The motor shaft of the servo motor is connected to the driving gear of the belt gear assembly. The push block is slidably connected to the first and second linear guide rails through the movable frame and faces the cargo discharge door. The two ends of the movable frame are connected to the ball nuts of the first and second ball screws, respectively. When goods are shipped, the servo motor drives the first and second ball screws to rotate through the belt and gear assembly, thereby driving the movable frame and push block to move towards the shipping door, pushing the goods on the carrying plate out of the shipping door. Its structure is simple and highly stable, which can prevent the goods from getting stuck at the shipping outlet of the shipping warehouse. Attached Figure Description

[0017] Example

[0018] Please see Figure 1 , Figure 2 This embodiment provides a microwave heating box drive mechanism for an automatic vending machine, including a dispensing compartment 1, a receiving plate 2, a dispensing door 3, and a goods ejection structure 4. The receiving plate 2 and the goods ejection structure 4 are disposed in the dispensing compartment 1, and a dispensing port is opened at one end of the dispensing compartment 1. The upper side of the dispensing door 3 is rotatably connected to the dispensing port of the dispensing compartment 1. Its structural principle is as follows: goods are received from the shelves of the automatic vending machine through the receiving plate 2, and the goods on the receiving plate 2 are ejected from the dispensing door 3 under the action of the goods ejection structure 4.

[0019] Specifically, the cargo ejection structure 4 includes a push block 41, a movable frame 42, a first linear guide rail 43, a second linear guide rail 44, a first ball screw 45, a second ball screw 46, a belt gear assembly 47, and a servo motor 48. The first linear guide rail 43 and the second linear guide rail 44 are arranged opposite each other on both sides of the cargo support plate 2. The first ball screw 45, the second ball screw 46, the belt gear assembly 47, and the servo motor 48 are arranged below the cargo support plate 2. One end of lever 46 is connected to the driving gear and driven gear of belt gear assembly 47, respectively. The other ends of the first ball screw 45 and the second ball screw 6 are rotatably connected to the loading compartment 1, respectively.
