Description

Technical Field

[0001] The utility model relates to the technical field of permanent magnet motors, in particular to a permanent magnet motor for a setting machine. Background Art

[0002] A setting machine is a device used for heat setting textiles and typically operates in high-temperature environments. Permanent magnet motors are widely used in setting machines due to their high efficiency, energy saving, and high-temperature resistance. Permanent magnet motors offer high efficiency, generally reaching IE4 and IE5 levels, as well as advantages such as small size, large starting torque, and high power factor. The protective net of a permanent magnet motor is typically used to protect the motor's internal components from damage by external factors, but most are secured with screws. This can be inconvenient when internal motor components need to be quickly replaced or repaired. Utility Model Content

The right surface of the positioning rod 15 is fixedly connected to a fixing ring 5, and the fixing ring 5 is threadedly sleeved with the protective shell 4. During the installation process of the motor body 1, the protective shell 4 is first clamped with the two pairs of connecting strips 10 fixed on the surface of the fixed shell 8 through the two pairs of limiting grooves 12 provided therein to ensure the consistency of the position.

[0024] The inner wall of the protective shell 4 is provided with two pairs of limit grooves 12, and the annular side surface of the fixed shell 8 is fixedly connected with two pairs of connecting strips 10. The two pairs of connecting strips 10 are respectively movably engaged with the two pairs of limit grooves 12, and the inner wall of the fixed shell 8 is provided with two pairs of connecting holes 11. The two pairs of connecting holes 11 are respectively movably engaged with the two pairs of limit rods 7. When engaged to the top, the fixing ring 5 is rotated left to drive the positioning rods 15 fixed thereto to move together. The positioning rods 15 will be engaged with the connecting shaft 6 and fit with the two pairs of limit rods 7 during the movement. As the positioning rods 15 continue to move, the two pairs of limit rods 7 are subjected to pressure and move toward opposite sides, pulling up the springs 18. When the positioning rods 15 move to the top, the two pairs of limit rods 7 are also engaged with the two pairs of connecting holes 11 opened in the fixed shell 8 for limiting. At this time, the protective shell 4 and the fixed shell 8 are in a limited and fixed state, and the overall connection is convenient, which greatly reduces the use of fixing screws and improves installation efficiency.

[0025] The surfaces of the two pairs of limit rods 7 are fixedly connected with connecting blocks 16, and the two pairs of connecting blocks 16 are movably engaged with the two pairs of hollow cylinders 17 respectively. The two pairs of connecting blocks 16 are fixedly connected with the two pairs of springs 18 respectively. The motor body 1 is fixedly connected with the ring 2 and the base 3 respectively. The two pairs of springs 18 are arranged in the two pairs of hollow cylinders 17.

During the resetting process of the two pairs of limit rods 7, they will be engaged with the connecting shaft 6, and the opposite ends of the two pairs of limit rods 7 will be disengaged from the engagement with the fixed shell 8. The limit is opened, and the protective shell 4 can be disassembled for easy cleaning to avoid blockage caused by dust accumulation, thereby affecting the overall heat dissipation efficiency.

[0026] Working principle:

[0027] During the installation of the motor body 1, the protective shell 4 is first clamped with the two pairs of connecting strips 10 fixed to the surface of the fixed shell 8 through the two pairs of limiting grooves 12 opened therein to ensure the consistency of the position. When it is clamped to the top, the fixing ring 5 is rotated to the left to drive the positioning rod 15 fixed thereto to move together. During the movement, the positioning rod 15 will be clamped into the connecting shaft 6 and fit with the two pairs of limiting rods 7. As the positioning rod 15 continues to move, the two pairs of limiting rods 7 are pressed to move toward the opposite backs, pulling up the spring 18. When the positioning rod 15 moves to the top, the two pairs of limiting rods 7 are also clamped into the two pairs of connecting holes 11 opened in the fixed shell 8. The protective shell 4 and the fixed shell 8 are limited. At this time, the overall connection is convenient, which greatly reduces the use of fixing screws and improves the installation efficiency. When disassembly is required, the fixing ring 5 is rotated in the opposite direction to drive the positioning rod 15 to move. During the outward movement of the positioning rod 15, the two pairs of limiting rods 7 are reset by the elastic force of the spring 18. During the resetting process of the two pairs of limiting rods 7, they will be clamped into the connecting shaft 6, and the opposite ends of the two pairs of limiting rods 7 are disengaged from the clamping with the fixed shell 8. The limit is opened, and the protective shell 4 can be disassembled, which is convenient for cleaning and avoids blockage caused by dust accumulation, thereby affecting the overall heat dissipation efficiency.
