Description

Technical Field

[0001] The utility model relates to the technical field of cooling conveyor lines, and particularly relates to a motor stator cooling and conveying device. Background Technique

[0002] The motor stator is an important and indispensable part of the motor. Its main function is to drive the rotor to rotate by generating a rotating magnetic field, so as to realize energy conversion and mechanical movement.

[0003] In the production and manufacturing of motor stators, a cooling conveyor line is generally required to cool them during the conveying process. However, it is found that during use, as the temperature of the motor stator decreases during movement, the temperature difference with the cold air becomes smaller, the cooling effect gradually decreases, and the corresponding cooling time will increase; at the same time, it is very difficult to concentrate the cold air to be conveyed onto the motor stator during the conveying process, and the effective utilization rate of the cold air is low.

[0004] Therefore, aiming at the deficiencies of the existing technology, it is necessary to design a motor stator cooling and conveying device to solve the above problems.

[0005] It should be noted that the above introduction to the technical background is only for the convenience of clearly and completely explaining the technical solution of the present utility model and facilitating the understanding of those skilled in the art.

The two ends of the protective cover are respectively provided with a discharge port and a material taking port. The exhaust fan increases the flow rate of the cold air at the conveyor line, and at the same time, the hot gas is discharged in time to avoid heat accumulation affecting the cooling effect.

[0013] Preferred technical solution: The outer periphery of the positioning tooling is made of nylon material, which makes it convenient for workers to take and place the motor stator.

[0014] Optimal technical solution: The protective cover is also provided with a safety door, and the safety door is provided with an observation window made of high-light-transmitting organic glass.
