Description

Technical Field

[0001] This utility model relates to the field of vending machine technology, and in particular to a pizza box positioning mechanism and a self-service pizza machine. Background Technology

[0002] Vending machines are commonly used equipment in commercial automation. They are not limited by time or location, save manpower, and facilitate transactions, representing a new form of commercial retail, often referred to as 24-hour mini-supermarkets. Furthermore, with market changes, vending machines have evolved into various styles, including those selling items such as pizzas.

[0003] Self-service pizza machines require pizzas to be placed in pizza boxes, which are then stored in a refrigerated or frozen container to maintain their quality over time. During operation, a conveying device removes the pizza from the storage container and delivers it to the opening mechanism. The opening mechanism positions the pizza box using a positioning mechanism, and a lifting mechanism then opens the box. A conveyor system transports the pizza from the box to a heating device for heating. After heating, the conveyor system removes the pizza, returns it to the box, and delivers it to the dispensing outlet.

[0004] Existing pizza box positioning mechanisms, such as those described in Chinese invention patent applications with application numbers CN202410529347.9, CN202410695561.1, and CN202410529017.X, position the pizza box during opening. Simultaneously, the opening mechanism of the opening device opens the pizza box and raises the pizza tray, facilitating the transport mechanism to move the pizza tray and the pizza inside.

[0005] Currently, the positioning mechanism uses a drive mechanism that guides four positioning components to converge towards the center to complete the positioning of the pizza box. While this method can achieve good positioning of the pizza box, it has a complex structure, high cost, and the guide groove design causes a certain lag in the guide plate's movement of the positioning components, preventing them from being pushed in real time.

[0006] In view of this, a new technical solution is needed to solve the above-mentioned technical problems. Utility Model Content

[0036] Example 1

[0037] See Figure 1-2 As shown, the pizza box positioning mechanism includes a mounting base 1, a drive mechanism 2, and a positioning component 3, as well as a transmission component 4. The drive mechanism 2 and the positioning component 3 are respectively mounted on the mounting base 1. The mounting base 1 is mounted on the opening device of the self-service pizza machine. The output end of the positioning component 3 extends out from the top of the mounting base 1 to limit the pizza box 5. The input end of the transmission component 4 is connected to the input end of the drive mechanism 2, and the output end of the transmission component 4 is connected to the positioning component 3 to drive the positioning component 3 to move towards the center.

[0038] The drive mechanism 2, positioning component 3 and transmission component 4 are respectively set in the mounting base 1. The structure is simple and the cost is low. Moreover, the drive mechanism 2 can directly drive the positioning component 3 to move through the transmission component 4 without any lag, which shortens the positioning time of the pizza box 5.

[0039] In a further specific embodiment, the transmission component 4 includes a turntable 41 and a connector 42. The turntable 41 is rotatably mounted on the mounting base 1. The first end of the connector 42 is connected to the turntable 41, and the second end of the connector 42 is connected to the positioning component 3. The first end of the connector 42 is rotatably mounted on the turntable 41, and the second end of the connector 42 is rotatably mounted on the mounting base 1. Through the arrangement of the turntable 41 and the connector 42, when the drive mechanism 2 drives the turntable 41 to rotate, the connector 42 can drive the positioning component 3 to move towards the center. It should be noted that in this embodiment, the number of positioning components 3 is four sets, corresponding to the four sides of the pizza box 5. In other specific embodiments, the number of positioning components 3 can be adjusted according to the number of sides of the pizza box 5.

[0040] In a further specific embodiment, the positioning component 3 includes a positioning element 31, a positioning seat 32, and a guide component 33. The bottom of the positioning element 31 is mounted on the positioning seat 32, the guide component 33 is mounted on the mounting base 1, the positioning seat 32 is slidably mounted on the guide component 33, and the second end of the connecting element 42 is connected to the mounting base 1. When the driving mechanism 2 moves the positioning seat 32 through the connecting element 42, it causes the positioning element 31 to move towards the center. It should be noted that in the prior art, the driving mechanism 2 moves the upper end of the positioning element 31 through the turntable 41. Under long-term use, the positioning element 31 is prone to tilting. In this embodiment, the connecting element 42 is directly connected to the positioning seat 32, so that the force applied by the driving mechanism 2 to the positioning element 31 is located below the positioning element 31, which can enhance the stability during movement and avoid tilting.

[0041] In a further specific embodiment, the guide assembly 33 includes a guide rail 331 and a slider 332. The guide rail 331 is mounted on the mounting base 1, the slider 332 is slidably mounted on the guide rail 331, and the mounting base 1 is mounted on the slider 332. The cooperation between the guide rail 331 and the slider 332 reduces friction during movement and enhances the stability of movement.

[0042] In a further specific embodiment, the top of the mounting base 1 has a limiting groove 11 for the positioning component 3 to pass through. By setting the limiting groove 11, the positioning component 31 can move on the limiting groove 11, thereby completing the limiting of the pizza box 5.

[0043] In a further specific embodiment, the mounting base 1 has a through hole in the middle, and the driving mechanism 2 is a rotary motor. The rotary motor is installed at the bottom of the mounting base 1, and the output end of the rotary motor extends into the mounting base 1 through the through hole and connects to the turntable 41. By driving the turntable 41 to rotate through the rotary motor, the four positioning parts 31 are respectively brought together to complete the positioning of the pizza box 5.

It should be noted that there are two fixed bases 22, which are respectively disposed at both ends of the lead screw 23. The output end of the driving member 21 is connected to the lead screw 23 to drive the lead screw 23 to rotate. The movable base 24 is installed on the lead screw 23. When the lead screw 23 rotates, it drives the movable base 24 to move along the lead screw 23. The first end of the connecting member 25 is installed on the movable base 24, and the second end of the connecting member 25 is installed on the turntable 41. When the movable base 24 moves, the connecting member 25 drives the turntable 41 to rotate.

[0046] In this embodiment, the driving component 21 is a motor, which drives the lead screw 23 to rotate, thereby causing the movable seat 24 to move on the lead screw 23. It should be noted that the movable seat 24 can also be a nut seat. When the movable seat 24 moves, the connecting component 25 drives the turntable 41 to rotate. In this embodiment, the second end of the connecting component 25 has a connecting groove, and the turntable 41 is provided with a connecting post. The connecting component 25 is fitted onto the connecting post through the connecting groove. During rotation, the connecting post moves within the connecting groove, allowing the turntable 41 to rotate while the movable seat 24 moves linearly.

[0047] It is understood that in this embodiment, a through groove is opened at the center of the mounting base 1, and a rotating shaft is provided at the center of the turntable 41. A bearing is installed on the rotating shaft, with the outer side of the bearing installed in the through groove and the inner side of the bearing installed on the rotating shaft, so that the turntable 41 can rotate at the center of the mounting base 1.

[0048] In a further specific embodiment, a first synchronous pulley 26, a second synchronous pulley 27, and a synchronous belt 28 are also provided between the drive member 21 and the lead screw 23.
