In this embodiment, the mounting rail 2, mounted on the mounting frame 1, provides a stable installation for the multiple conveying motors 3. The continuous arrangement of the multiple conveying motors 3 along the conveying direction of the mounting rail 2 saves space and facilitates collaborative work between the motors, achieving efficient conveying. Regarding motor mounting, mounting element 4 securely fixes the fixed end of the conveyor motor 3 to the mounting guide rail 2, ensuring that the motor will not shift or loosen during operation. This guarantees the stability and reliability of the entire conveying system and reduces the probability of failures caused by motor vibration. The multiple hub interfaces 51 of the hub 5 can be easily and quickly connected to the control interfaces of multiple conveyor motors 3, greatly simplifying the wiring process and effectively avoiding the problems of complex and confusing wiring in traditional wiring methods, significantly improving wiring efficiency. At least one output interface 52 is electrically connected to the hub interface 51, enabling unified signal transmission and control of multiple motors, achieving centralized management. This makes the control of the entire multi-motor conveying system more convenient and precise, improving the overall system operating efficiency and performance, and is suitable for complex working scenarios with multiple motor connections.

[0029] The mounting frame 1 is assembled from multiple profile square bars 11, with supporting corner ribs 12 positioned between adjacent profile square bars 11 to securely connect them. In this embodiment, the mounting frame 1 has a stable structure, with each profile square bar 11 precisely positioned, ensuring stable and reliable wiring and connection for multiple motors.

[0031] See Figure 5 As shown, the mounting element 4 includes a base 41, a connecting part 42, and a fixing part 43 connected in sequence. The mounting element 4 has an internal cavity 44 that extends through the base 41, connecting part 42, and fixing part 43.

A positioning part 422 is provided at the end of the connecting part 42 near the fixing part 43; the positioning part 422 is used for axial positioning of the mounting element 4 during installation. The fixing part 43 has a locking end 431 for locking and fixing the mounting element 4. In this embodiment, the sequentially connected base 41, connecting part 42, and fixing part 43, together with the internally extending cavity 44, provide a stable mounting for the motor.

The through slot 421 of the connecting part 42 connects to the cavity 44, which can be used for motor control wiring to ensure the coordinated operation of various components of the motor conveying mechanism. The presence of the positioning part 422 ensures that the mounting element 4 is accurately positioned in the axial direction during installation, which greatly improves the accuracy and consistency of the seat installation, thereby enhancing the overall operational stability of the multi-motor conveying mechanism. The locking and fixing end 431 of the fixing part 43 can reliably lock and fix the mounting element 4, effectively preventing the seat from loosening or shifting under complex working conditions such as high-speed operation and frequent start-stop of multiple motors, thus ensuring the stability and accuracy of transmission between motors.

[0032] The mounting guide rail 2 is provided with a mounting positioning groove 21 and a mounting through hole 22. The mounting through hole 22 extends along the depth direction of the mounting positioning groove 21. The positioning part 422 is used to cooperate with the mounting positioning groove 21.

Specifically, the locking fixing end 431 includes a threaded part provided in the fixing part 43. The threaded part is used to cooperate with the nut to lock the mounting element 4 into the mounting through hole 22. In this embodiment, the cooperation between the mounting positioning groove 21 and the positioning part 422 can accurately determine the position of the mounting element 4 on the mounting guide rail 2, ensuring the accuracy of the installation position of each motor and providing a stable foundation for multi-motor collaborative work. Precise positioning effectively avoids the problem of conveying synchronization caused by motor installation deviation and improves the conveying accuracy. The design of the mounting through hole 22, the fixing part 43, the locking fixing end 431, and the nut realizes a stable connection between the mounting element 4 and the mounting guide rail 2. In multi-motor conveying processes, facing complex vibrations and impacts, a robust connection ensures that the motor remains in the correct position, preventing loosening and displacement, and guaranteeing continuous and stable motor operation. The fit between the threaded part and the nut facilitates installation and disassembly, allowing for quick assembly and disassembly of the motor during equipment maintenance or component replacement, thus improving maintenance efficiency.

[0033] The positioning part 422 includes positioning planes 423 disposed opposite to each other on both sides of the connecting part 42, the positioning planes 423 being parallel to each other; the positioning planes 423 are used to cooperate with the mounting positioning groove 21 to position the installation direction of the mounting element 4. In this embodiment, the positioning planes 423, which are parallel to each other on both sides, cooperate with the mounting positioning groove 21 to accurately position the installation direction of the mounting element 4. This ensures the consistency of the installation direction of each mounting element 4, avoids asynchronous motor operation caused by deviation in installation direction, and thus effectively improves the collaborative operation capability of the entire conveying mechanism. Precise positioning helps reduce mechanical wear caused by inaccurate installation, extending the service life of the mounting element 4 and the entire mechanism.

The end cover 33 is located at one end of the rotor housing 321 and is connected to the connecting part 42. The control board 35 is located between the base 41 and the connecting part. The through slot 421 is used for wiring of the control board 35.

In this embodiment, the stator assembly 31 is stably disposed on the base 41 and cooperates with the rotor magnet 322 disposed on the inner diameter of the rotor housing 321 and opposite to it, providing a stable magnetic field interaction environment for motor operation, ensuring that electrical energy can be accurately and efficiently converted into mechanical energy when multiple motors are conveying, and ensuring the stability and accuracy of material conveying. The rotating shaft assembly 34 is reliably connected to the rotor housing 321 and placed in the cavity 44, which not only ensures the flexible rotation of the motor rotor, but also effectively reduces the interference between motors when multiple motors work together, improving the operational reliability of the entire conveying mechanism. The reasonable connection between the end cap 33, one end of the rotor housing 321, and the connecting part 42 enhances the overall integrity of the motor structure. During multi-motor conveying, it effectively resists vibration and external impact, prevents motor components from loosening, and extends the motor's service life. The control board 35 is positioned between the base 41 and the connecting seat, and utilizes the through slot 421 for wiring, achieving an orderly layout of the multi-motor control circuitry. This facilitates centralized control and maintenance, reduces the risk of malfunctions caused by chaotic wiring, and improves the convenience and efficiency of controlling the multi-motor conveying mechanism. The fixing holes 412 and connecting posts 413 on the connecting platform 411 provide precise positioning and stable support for the installation of the control board 35 and the end cap 33, contributing to the standardized assembly and rapid assembly of the multi-motor conveying mechanism.

The positioning step 441 positions the end face of the bearing 341, providing stable support for the shaft assembly 34. This ensures the rotating shaft 342 maintains good coaxiality and operational accuracy during high-speed rotation, effectively reducing vibration and noise. The reliable connection between each motor rotor and the rotating shaft 342 enables efficient power transmission, achieving synchronous and coordinated operation of multiple motors, precise control of conveying speed and direction, and meeting the needs for fast, stable, and precise material or workpiece conveying under different working conditions, thus improving the overall performance and reliability of the conveying mechanism.
