[0002] Its main working principle is to convert mechanical energy into heat energy. The heat generated when the machine rotates will press the food to cook it. The most obvious feature of puffed food is that its volume increases.

[0003] In the existing technology, corn puffing machines produce puffed food by heating the corn during the process of conveying it through the screw shaft, causing the corn to expand due to heat. However, during the long-term heating process, the internal structure of the screw shaft of the corn puffing machine will expand due to heat, which will affect the use of the bearings at both ends of the screw shaft. There is an urgent need for a new type of screw shaft for corn puffing machines to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a screw shaft for a corn puffing machine, thereby solving the problems mentioned in the background art. This utility model is highly practical, as it uses two sets of support components to support the rotation of the screw shaft within the corn puffing machine. When the screw shaft expands due to heat during rotation, the rotating support wheel automatically adjusts according to the expansion range of the connecting ring, automatically adapting to different states of the corn puffing machine screw shaft without the need for bearings.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a corn puffing machine screw shaft, comprising a corn puffing machine screw shaft body and two mounting rings, wherein connecting rings are fixedly connected to both the left and right ends of the corn puffing machine screw shaft body, and oil inlet pipes are fixedly connected to the adjacent ends of the two mounting rings.

[0006] Each of the two mounting rings has a support assembly at its close end. One set of support assemblies includes three sliding rods, three limiting plates, three springs, three docking sliders, and three rotating support wheels. The three sliding rods are slidably connected to the circumferential surface of the mounting ring. The three limiting plates are fixedly connected to the upper ends of the three sliding rods. The three springs are slidably connected to the circumferential surface of the three limiting plates. The three docking sliders are fixedly connected to the lower ends of the three limiting plates. The three rotating support wheels are rotatably connected to the circumferential surface of the three docking sliders.

[0007] Furthermore, support rods are fixedly connected to both ends of the screw shaft of the corn puffing machine, and limit rings are fixedly connected to the circumferential surfaces of the two support rods. The two limit rings are rotatably connected to the two mounting rings.

[0008] Furthermore, three fixing blocks are fixedly connected to the circumferential surfaces of both mounting rings.

[0009] Furthermore, the surface of the mounting ring is provided with a heat insulation layer, and the two oil inlet pipes are aligned with two of the rotating support wheels.

[0010] Furthermore, the two docking sliders are slidably connected within the two mounting rings, respectively.

[0011] Furthermore, the two sets of rotating support wheels are in contact with each other and the two connecting rings.

[0012] The beneficial effects of this utility model are as follows: This utility model provides a screw shaft for a corn puffing machine. Because it incorporates two connecting rings, three sliding rods, three limiting plates, three springs, three docking sliders, and three rotating support wheels, our design improvements and practical use have shown that this device has a reasonable structure and good practicality.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1-9 This utility model provides a technical solution: a screw shaft for a corn puffing machine, comprising a screw shaft body 1 and two mounting rings 4. Connecting rings 7 are fixedly connected to both ends of the screw shaft body 1. Oil inlet pipes 6 are fixedly connected to the adjacent ends of the two mounting rings 4. Support assemblies are provided at the adjacent ends of the two mounting rings 4. One set of support assemblies includes three sliding rods 12, three limiting plates 5, three springs 10, three docking sliders 11, and three rotating support wheels 8. The three sliding rods 12 are slidably connected to the circumferential surface of the mounting rings 4, and the three limiting plates 5 are respectively fixedly connected to the three... At the upper end of the sliding rod 12, three springs 10 are slidably connected to the circumferential surfaces of three limiting plates 5, and three docking sliders 11 are fixedly connected to the lower ends of the three limiting plates 5. Three rotating support wheels 8 are rotatably connected to the circumferential surfaces of the three docking sliders 11. This design solves the problem that in the original device, corn puffing machine screw shaft 1 is heated during the process of conveying corn to make puffed food, but the internal structure of the corn puffing machine screw shaft 1 will expand due to heat during long-term heating, which will affect the use of the bearings at both ends of the corn puffing machine screw shaft 1.

[0026] As the first embodiment of this utility model: Support rods 2 are fixedly connected to both ends of the screw shaft 1 of the corn puffing machine. Limiting rings 9 are fixedly connected to the circumferential surfaces of both support rods 2. The two limiting rings 9 are rotatably connected to two mounting rings 4. The support rod 2 installed at one end of the screw shaft 1 can be connected to an external bracket to support the rotation of the screw shaft 1. The support rod 2 installed at the other end of the screw shaft 1 can be fixedly connected to the output end of a motor, enabling the motor to drive the screw shaft 1 to rotate, thereby moving the corn within the corn puffing machine. Three fixed connecting blocks 3 are fixedly connected to the circumferential surfaces of the two mounting rings 4, which can be connected to the internal bracket of the corn puffing machine to support the rotation of the screw shaft 1. When the screw shaft 1 expands due to heat, the rotating support wheel 8 will displace according to the collision range of the connecting ring 7. The surface of the mounting ring 4 is provided with a heat insulation layer. Two oil inlet pipes 6 are aligned with two of the rotating support wheels 8. The heat insulation layer on the surface of the mounting ring 4 reduces the heat transferred from the screw shaft 1 of the corn puffing machine to the mounting ring 4, preventing expansion of the mounting ring 4 structure. Two docking sliders 11 are slidably connected within the two mounting rings 4 and can be used to mount the rotating support wheels 8. The two sets of rotating support wheels 8 are in contact with the two connecting rings 7, so that the rotating support wheels 8 are in contact with the surface of the connecting rings 7 under the elastic force of the spring 10. The two sets of rotating support wheels 8 form a bearing to support the rotation of the screw shaft 1 of the corn puffing machine.

[0027] As a second embodiment of this utility model: First, one of the support rods 2 is installed on the bracket inside the corn puffing machine, and the other support rod 2 is fixedly connected to the motor output end. Then, the fixed connecting block 3 is fixedly installed inside the corn puffing machine with bolts. Lubricating oil is introduced into the oil inlet pipe 6. When the motor drives the corn puffing machine screw shaft 1 to rotate, the corn puffing machine screw shaft 1 will rotate under the support of two sets of rotating support wheels 8. At the same time, the support rod 2 limits the position of the corn puffing machine screw shaft 1 to prevent the corn puffing machine screw shaft 1 from being displaced. When the corn puffing machine screw shaft 1 is heated and its structure expands, its structure will push the rotating support wheels 8 to move outward. After the two sets of rotating support wheels 8 are displaced, they can still support the rotation of the corn puffing machine screw shaft 1. When the corn puffing machine screw shaft 1 is in a cold environment, the structure of the corn puffing machine screw shaft 1 contracts, and the two sets of rotating support wheels 8 will move in contact with the corn puffing machine screw shaft 1.
