[0002] In the gas scale drive system, the efficiency of torque transmission and the smooth operation of the system are the key factors to evaluate the system performance. With the continuous expansion of industrial application fields, the performance requirements of gas scale systems are also increasing. The traditional gas scale adopts the direct drive of the motor. Although it can meet the basic driving requirements, it has significant limitations in high torque output, energy consumption reduction and stability.

[0003] First, high torque output is crucial for the gas scale system. In some application scenarios, such as heavy-load startup or high-resistance conditions, the gas scale needs a large torque to overcome resistance and achieve stable operation. However, the traditional motor direct drive method is limited in torque transmission efficiency and it is difficult to provide enough torque to meet these needs. Secondly, reducing energy consumption is one of the important pursuits of modern industrial systems. The traditional motor direct drive method is not energy efficient during operation due to factors such as friction and heat loss. This not only increases operating costs, but also creates unnecessary burdens on the environment. Therefore, we have made improvements to this and proposed a vacuum gas scale. Summary of the invention

Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0027] As described in the background technology, traditional gas scales use direct motor drive, which can meet basic driving requirements, but has significant limitations in high torque output, reduced energy consumption and stability. First, high torque output is crucial for gas scale systems. In certain application scenarios, such as heavy-load starting or facing high-resistance conditions, gas scales require a larger torque to overcome resistance and achieve stable operation. However, the traditional direct motor drive method is limited in torque transmission efficiency and it is difficult to provide enough torque to meet these requirements. Secondly, reducing energy consumption is one of the important pursuits of modern industrial systems. During operation, the traditional direct motor drive method is not energy efficient due to factors such as friction and heat loss. This not only increases operating costs, but also creates unnecessary burdens on the environment.

[0028] In order to solve this technical problem, the utility model provides a vacuum air scale.

[0032] The vacuum air scale provided by the utility model adopts a worm gear 314 and a worm 313 to transmit the power of the drive motor 312. The design of the worm gear 314 and the worm 313 allows a larger output torque to be generated with a smaller input torque, which means that the torque can be transmitted more effectively when driving the air scale, especially in applications requiring high torque; the worm gear 314 and the worm 313 also have a deceleration function, that is, increasing the torque while reducing the rotation speed. This feature enables the drive motor 312 to run at a lower speed when driving the air scale, thereby improving the operating efficiency and reducing energy consumption. The motion characteristics of the worm gear 314 and the worm 313 make the output motion smoother and reduce vibration and impact.

[0033] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

The present application adopts a worm wheel 314 and a worm 313 to transmit the power of the driving motor 312. The design of the worm wheel 314 and the worm 313 allows a larger output torque to be generated with a smaller input torque, which means that when driving an air pound, torque can be transmitted more effectively, especially in applications requiring high torque; the worm wheel 314 and the worm 313 also have a deceleration function, that is, reducing the speed while increasing the torque. This characteristic enables the driving motor 312 to run at a lower speed when driving the air pound, thereby improving the operating efficiency and reducing energy consumption. The motion characteristics of the worm wheel 314 and the worm 313 make the output motion smoother and reduce vibration and impact.

[0038] Further, such as Figure 1-Figure 4 As shown, the vacuum generating part includes an air scale upper cover 306 installed at the bottom of the gear box lower cover 310, the bottom of the air scale upper cover 306 is connected to the air scale lower cover 309, and the air scale upper cover 306 is connected to the air scale exhaust connecting pipe 305, which is used to connect to the target area.

[0039] Further, such as Figure 4 As shown, a gas scale rotor 308 is arranged in the gas scale upper cover 306, and a plurality of rotors are arranged on the gas scale rotor 308, and the number of rotors is at least two. During the rotation of the gas scale rotor 308 driving the rotor, the air in the target area can be extracted through the gas scale exhaust connection pipe 305 to form a vacuum environment in the target area.

When the sealing piston 324 is inserted into the piston chamber 318, the piston chamber 318 can be sealed, and then the air inlet 322 is sealed. When the air intake button 325 is pushed, the air intake button 325 drives the sealing piston 324 to move through the air intake connecting rod 323 to separate the sealing piston 324 from the piston chamber 318. At this time, the outside air enters the piston chamber 318 from the connection between the air intake connecting rod 323 and the gas scale end cover 315, and then enters the gas scale upper cover 306 from the air inlet port 322, and finally enters the target area through the gas scale exhaust connecting pipe 305 to release the vacuum adsorption.
