[0002] A mixing mill generally refers to a type of equipment used in rubber processing, which is mainly used to mix rubber raw materials to make the rubber soft and easy to process, as well as to improve the physical properties of the rubber. Permanent magnet motors generally have high torque density, that is, they can provide greater torque in a relatively small volume, which is important for mixing mill applications that require high torque, as this helps drive components such as rollers for an efficient mixing process. The integrated dual-machine dual-output design means that two motors and two output shafts are integrated into one unit. This design can make the entire system more compact, reduce the occupied space, and help better integrate the mixing mill in limited factory space.

[0003] The traditional drive method is a high-speed motor plus a dual-output shaft reducer. The drive system is bulky, occupies a large area, and is heavy. The high-speed part of the transmission system is the focus of equipment noise, vibration, and failure.

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Reference Figure 1-3 The utility model provides an embodiment: an integrated dual-machine dual-output permanent magnet motor for an open mill, comprising a casing 1, a motor cavity 1 2 is provided on one side of the casing 1, a motor cavity 2 3 is provided on the other side of the casing 1, an output shaft 1 4 is rotatably connected to one side of the outer wall of the casing 1, an output shaft 2 5 is rotatably connected to the other side of the outer wall of the casing 1, the output shaft 1 4 penetrates the side wall of the casing 1 and extends to the inside of the motor cavity 1 2, the output shaft 2 5 penetrates the side wall of the casing 1 and extends to the inside of the motor cavity 2 3, the motor cavity 1 2 and the motor cavity 2 3 are symmetrically distributed, and the output shaft 1 4 and the output shaft 2 5 are symmetrically distributed;

[0021] Specifically, the mixing mill is a very important equipment in the rubber industry, and the integrated dual-machine dual-output permanent magnet motor is one of the core components of the mixing mill. This motor has a structure of an integrated dual-machine housing 1 and is composed of two motors. Each motor has an independent housing 1 and an output shaft. This design allows the two motors to operate independently without interfering with each other, thereby meeting the requirements of different working speeds of the two rollers of the mixing mill. The integrated dual-machine dual-output permanent magnet motor is a low-speed permanent magnet synchronous motor that can directly drive the mixing mill. The use of this motor can shorten the size chain of the mixing mill and improve the compactness and reliability of the equipment. In addition, due to the use of permanent magnet synchronous motors, it can provide a more stable and smoother speed, thereby improving the production efficiency and product quality of the mixing mill. In addition to having excellent performance and structural characteristics, the integrated dual-machine dual-output permanent magnet motor also has a wide range of applications. It can be applied to various specifications and models of mixing mills to meet the needs of different production processes. In addition, due to its low speed and high torque characteristics, it can also be used in other occasions requiring low speed and high torque drive, such as plastic machinery, chemical fiber machinery, etc.

[0022] Reference Figure 1-3 , the motor cavity 2 3 and the motor cavity 1 2 do not interfere with each other, the center distance between the motor cavity 1 2 and the motor cavity 2 3 is the same as the center distance of the mixing mill roller, and the center distance between the output shaft 1 4 and the output shaft 2 5 is the same as the center distance of the mixing mill roller;

[0023] Specifically, the structural design of the integrated dual-machine casing 1 makes full use of the existing space and effectively improves the torque density of the motor. This structure includes a motor cavity 1 2 and a motor cavity 2 3, which are located together in a casing 1. This design makes the center distance of the two motor cavities the same as the center distance of the mixing mill rollers, thereby achieving a perfect match between the motor and the mixing mill. The design of the motor cavity 1 2 and the motor cavity 2 3 takes into account the heat dissipation and noise control of the motor. Each motor cavity is equipped with an independent heat dissipation system to ensure that the motor maintains stable performance during long-term operation. In addition, the design of the motor cavity also takes into account noise control. By adopting advanced sound insulation materials and optimized design, the noise is reduced to At the lowest level, output shaft 1 4 and output shaft 2 5 are the core components of the motor, which are responsible for transmitting the power of the motor to the mixing mill rollers. The center distance of the two output shafts is the same as the center distance of the mixing mill rollers, ensuring that the power output of the motor matches the operating requirements of the mixing mill. This design not only improves the transmission efficiency of the motor, but also reduces the additional wear and energy consumption caused by transmission mismatch. The structural design of the integrated dual-machine casing 1 also takes into account the convenience of maintenance and servicing. Since the two motor cavities are located in the same casing 1, maintenance personnel can easily check and maintain the two motors at the same time. This design reduces maintenance time and cost and improves the operating efficiency of the equipment.

[0024] Working principle: The permanent magnet motor optimizes the design of traditional drive, improves the torque density of the drive system, reduces the volume of the system, reduces the floor space, reduces construction costs, has a large torque and low speed design, directly drives the equipment, shortens the transmission chain, reduces equipment noise and vibration, reduces failure points, increases equipment life, improves transmission efficiency, reduces maintenance costs, and is easy to install. The permanent magnet motor is set to have dual output ends of output shaft 1 4 and output shaft 2 5, which are directly connected to the equipment, and the size of output shaft 1 4 and output shaft 2 5 are the same as the size of the double rollers of the equipment, which is convenient for installation and reduces the difficulty of installation.

[0025] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
