[0044] Reference Figure 1~Figure 4 , which is the first embodiment of the utility model, proposes

[0045] An overload protection transmission device, comprising:

[0046] Rack 100;

[0047] A driving member 200 is disposed on the frame 100;

[0048] A stirring member 300 is rotatably disposed on the frame 100;

[0049] The belt 400 is wound around the driving member 200 and the stirring member 300. The driving member 200 drives the stirring member 300 to rotate through the belt 400. After the stirring member 300 stops stirring, the belt 400 is slidably disposed on the driving member 200 and the stirring member 300.

[0050] In this embodiment, in order to solve the problem of directly increasing the load of the motor and causing irreversible damage to the entire transmission system in the related art, the frame 100 is the foundation of the entire device, providing a stable installation platform for the driving member 200, the stirring member 300 and the transmission system. The driving member 200 is arranged on the frame 100, as a power source, providing power output, is the source of the system operation, and drives the start and stop of the stirring member 300. The stirring member 300 is in direct contact with the material and is installed on the frame 100. The material stirring operation is realized through the transmission of the belt 400. The belt 400 is wound between the driving member 200 and the stirring member 300, and the friction force is used to transmit power to drive the stirring member 300 to rotate. When overloaded, the stirring resistance increases, and the sliding design of the belt 400 plays a role, allowing the belt 400 to slide relative to the driving member 200 when the stirring member 300 stops, reducing the damage to the motor 220. This embodiment realizes intelligent response to overload through the sliding design of the belt 400, which not only protects the driving member 200 but also optimizes the overload response capability of the overall device. The belt 400 can be a V-belt. In extreme cases, the stirring member 300 may be locked, and the driving member 200 drives the V-belt to idle without increasing the load of the driving member 200, which can effectively protect the driving member 200 and the stirring member 300.

[0051] Further, the driving member 200 includes:

[0052] The motor 220 is disposed on the frame 100 and has a driving end;

[0053] The first pulley 240 is disposed on the motor 220 , and the belt 400 is wound around the first pulley 240 .

[0054] In this embodiment, the motor 220 is directly mounted on the frame 100 as a driving force source to provide basic energy output. The motor 220 is the source of the entire system startup. The motor 220 in this embodiment is a multi-stage motor. The first pulley 240 is arranged on the shaft of the motor 220. The first pulley 240 directly receives the output of the motor 220 and transfers the kinetic energy to the belt 400 to achieve primary energy conversion. This embodiment realizes the effective control and efficient and stable transmission of the power of the motor 220, ensures the optimization of the entire power chain on the frame 100, improves the working performance and the reliability and efficiency of the system, reduces energy consumption, and is suitable for operating environments such as mixing. The existing table modification machine mixing mechanism uses a motor to drive a reducer to drive the mixer in order to achieve the two purposes of reducing the speed and increasing the torque. This embodiment uses a multi-pole motor to preliminarily achieve the above two purposes, and then selects the first pulley 240 with different diameter ratios for different working conditions, so as to achieve the purpose of reducing to a specific speed and increasing to a specific torque.

[0055] Further, the stirring member 300 includes:

[0056] The second pulley 310 is rotatably disposed on the frame 100, and the belt 400 is wound around the second pulley 310 and the first pulley 240 at the same time;

[0057] The stirring unit 320 rotates on the frame 100 , and the second pulley 310 drives the stirring unit 320 to rotate.

[0058] In this embodiment, the belt 400 is wound around the second pulley 310. The belt 400 serves as a medium for power transmission, ensuring a smooth transition of energy from the motor 220 output to the stirring unit 320, which is effective and stable. The stirring unit 320 rotates directly on the frame 100. The stirring unit 320 is driven by the second pulley 310 and rotates and performs stirring operations through the power transmitted by the belt 400. This embodiment achieves efficient and precise control of the transmission, ensures the reliable operation of the stirring unit 320, optimizes the stability and overall efficiency of the stirring process, improves the uniformity of stirring, is suitable for different material requirements, and demonstrates the flexibility and practicality of the design. The existing stirring mechanism of the table modification machine uses the motor 220 to drive the reducer, and then drives the stirring unit 320, that is, all of them adopt a rigid connection method. Once the bearing of the stirring unit 320 is locked or the stirring unit 320 is blocked, the excess resistance generated will be reversely transmitted to the reducer and the motor 220 through a rigid connection method without loss, causing greater mechanical wear and electrical load, and eventually causing the motor 220 to be overloaded and the reducer to be damaged or even scrapped. This transmission system eliminates the use of a reducer, and uses large and small pulleys as a reduction mechanism. The first pulley 240 is a small pulley, and the second pulley 310 is a large pulley. A V-belt is used as a transmission medium, and a flexible connection method is used to avoid the direct and lossless transmission of the excess resistance generated by the bearing locking or the blocking of the stirring unit 320 to the drive motor. In extreme cases, the first pulley 240 will be locked, and the motor 220 will drive the second pulley 310 to drive the V-belt to idle, which will not increase the load of the motor, and can effectively protect the motor and the stirring unit 320.

[0059] Further, the stirring unit 320 includes:

[0060] The rotating shaft 321 is disposed on the first pulley 240 and is rotatably disposed on the frame 100;

[0061] A first bevel gear 330 is disposed on the rotating shaft 321;

[0062] The second bevel gear 340 is rotatably disposed on the frame 100. The second bevel gear 340 is meshed with the first bevel gear 330. When the first bevel gear 330 rotates, it drives the second bevel gear 340 to rotate.

[0063] The stirring paddle 350 is disposed on the second bevel gear 340 .

[0064] In this embodiment, the first bevel gear 330 is placed on the second pulley 310. With the rotation of the frame 100, the first bevel gear 330 not only cooperates with the second pulley 310, but also undertakes power conversion. The second bevel gear 340 is meshed with the first bevel gear 330. Through precise gear engagement, after the first bevel gear 330 rotates, the second bevel gear 340 immediately responds, achieving efficient power transmission. This design ensures smooth transmission and minimizes power loss. The stirring paddle 350 is directly set on the second bevel gear 340. The rotation of the second bevel gear 340 directly drives the stirring paddle 350 to rotate, ensuring the efficient rotation of the stirring paddle 350, making the material mixing process more uniform and powerful.

[0065] Further, the first bevel gear 330 rotates in the horizontal direction, and the second bevel gear 340 rotates in the vertical direction.

[0066] In this embodiment, the first bevel gear 330 rotates in the horizontal direction, and the second bevel gear 340 adopts a vertical axis. After meshing with the first bevel gear 330, the power transmission becomes a vertical rotation. This design allows the stirring to penetrate the material more fully, improves the penetration of the stirring, and especially mixes the materials evenly in the vertical direction. This embodiment not only enhances the multidimensionality of stirring, but also ensures that the materials are fully and deeply mixed in the container. Whether in the horizontal or vertical direction, it has been optimized, improving the comprehensive effect of stirring, and showing the three-dimensionality and practicality of stirring.

[0067] Further, the first bevel gear 330 is rotatably and slidably disposed on the frame 100, and further includes:

[0068] The pusher 360 is disposed on the frame 100 . After the stirring paddle 350 stops rotating, the pusher 360 pushes the first bevel gear 330 to slide. After sliding, the first bevel gear 330 and the second bevel gear 340 move away from each other.

[0069] In this embodiment, the first bevel gear 330 is slidably disposed on the frame 100, ensuring the flexible arrangement of the first bevel gear 330. When the stirring paddle 350 stops rotating, the pusher 360 starts its function and pushes the first bevel gear 330 to slide. At this time, the first bevel gear 330 slides through the thrust of the pusher 360 to achieve dynamic adjustment with the second bevel gear 340 and stay away from the second bevel gear 340. This design improves the flexibility of operation. This embodiment provides active control means after the stirring stops through the integration of the sliding of the first bevel gear 330 and the pusher 360, improves the adjustability and operation accuracy during the stirring process, allows the stirring paddle 350 and the material conditions to be dynamically adjusted according to demand, optimizes the stirring state, and demonstrates the intelligent control and delicate operation of the stirring unit 320.

[0070] further,

[0071] The pusher 360 includes:

[0072] The pin shaft 370 has one end disposed on the rotating shaft and the other end disposed on the first bevel gear 330. When the first bevel gear 330 stops rotating, the pin shaft 370 breaks.

[0073] The pushing unit is disposed on the frame 100 , and after the stirring paddle 350 stops rotating, the pushing unit pushes the pin shaft 370 to slide.

[0074] The first pulley 240 and the second pulley 310 each include:

[0075] Rotating wheel 380;

[0076] A rotating ring 390 is rotatably arranged on the outer ring of the rotating wheel 380;

[0077] The clamping member 3100 has one end disposed on the rotating wheel 380 and the other end is used to be clamped on the rotating ring 390 to drive the rotating ring 390 to rotate or not rotate.

[0078] The rotating wheel 380 has a sliding hole 3110, the rotating ring 390 has a clamping hole 3120, and the clamping member 3100 includes: a sliding block 3130, which is slidably disposed in the sliding hole 3110, and slides out and then slides into the clamping hole 3120;

[0079] The elastic member 3140 has one end disposed in the sliding hole 3110 and the other end disposed on the slider 3130 . The elastic member 3140 is used to provide a force for the slider 3130 to slide out of the sliding hole 3110 .

[0080] In this embodiment, in order to prevent the motor 220 from being damaged and reduce the damage to the belt 400, two solutions are designed in this embodiment. One is to connect the first bevel gear 330 and the rotating shaft 321 with a pin shaft 370. When the motor 220 continues to rotate, the stirring paddle 350 stops rotating, and a huge force is generated between the first bevel gear 330 and the second bevel gear 340, causing the pin shaft 370 to break. The pushing member 360 can be but is not limited to a spring. After the pin shaft 370 breaks, the spring contracts, driving the first bevel gear 330 and the second bevel gear 340 to disengage, and the first bevel gear 330 idles without damaging the motor 220. Secondly, the first pulley 240 and the second pulley 310 are designed to be a structure of a rotating wheel 380 and a rotating ring 390. Since the elastic member 3140 has a certain elastic force, when the stirring paddle 350 and the motor 220 rotate normally, the slider 3130 is stuck in the clamping hole 3120, and the rotating ring 390 and the rotating wheel 380 rotate synchronously. When the stirring paddle 350 stops unexpectedly and the motor 220 is still rotating, the slider 3130 is first disengaged from the clamping hole 3120, and the rotating ring 390 and the rotating wheel 380 rotate relative to each other, which will neither damage the motor 220 nor wear the belt 400, thereby reducing maintenance costs.

[0081] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
