[0013] Compared with the prior art, the beneficial effects of the utility model are:

However, due to the contact between the conical block and the trapezoidal block, the springs cannot pull the two heat sinks to reset. When the conveyor line is completed, the reduction motor is turned off, the moving mechanism is reset, and the distance that the sliding rod slides out of the heat sink increases. The conical block is reset, and the two springs on the same side are restored and drive the two heat sinks to reset.

[0015] (2) The heat dissipation structure of the reduction motor dedicated to the conveyor line is such that when the fan blades rotate, the wind generated contacts the surface of the wind contact block, and due to the arc-shaped grooves on the wind contact block, the force area of ​​the wind contact is increased, so that the wind contact block moves toward the heat sink and simultaneously drives the sleeve ring to move toward the heat sink. When the fan blades stop working, the second spring pulls the T-block to reset. In this way, the stability of the device during use is improved as much as possible, and the practicality of the device is increased as much as possible. BRIEF DESCRIPTION OF THE DRAWINGS

When the reduction motor 5 is turned on to start the conveyor line working, the output end of the reduction motor 5 drives the fan mechanism to rotate, and the wind generated by the rotation of the fan mechanism blows toward the main body of the reduction motor 5, and due to the shielding of the protective cover 6, the wind blows toward the heat sink 12.

When the fan blade 9 rotates, the generated wind contacts the surface of the wind contact block 10, and due to the arc-shaped groove provided on the wind contact block 10, the force area of ​​the wind contact is increased, so that the wind contact block 10 moves toward the heat sink 12, and the collar 11 is simultaneously driven to move toward the heat sink 12, and when the fan blade 9 stops working, the second spring 18 pulls the T-block 17 to reset.

[0037] Working principle: when the reduction motor 5 is turned on to start the conveyor line working, the output end of the reduction motor 5 drives the fan mechanism to rotate, and the wind generated by the rotation of the fan mechanism blows toward the main body of the reduction motor 5, and due to the shielding of the protective cover 6, the wind blows toward the heat sink 12, and at the same time, the rotation of the fan mechanism drives the moving mechanism to move, and the moving mechanism drives the collar 11 to move toward the heat sink 12, and drives the sliding rod 14 to slide into the heat sink 12. The distance increases, the sliding rod 14 drives the conical block 21 to move synchronously, and the inclined surfaces on both sides of the conical block 21 push the two trapezoidal blocks 22 to contact and push the two trapezoidal blocks 22 to move synchronously, so that the two heat sinks 13 rotate to both sides at a certain angle, and the two springs 15 on the opposite side are stretched by force, but because the conical block 21 is in contact with the trapezoidal block 22, the spring 15 cannot pull the two heat sinks 13 to reset. When the conveyor line is completed, the reduction motor 5 is turned off, the moving mechanism is reset, and the distance driven by the sliding rod 14 to slide out of the heat sink 12 increases, and the conical block 21 is reset. At this time, the two springs 15 on the same side are restored. The two heat sinks 13 are driven to reset. When the reduction motor 5 is working, the output end of the reduction motor 5 drives the fan blades 9 to rotate and is protected by the protective cover 6 to prevent the staff from being injured by the fan blades 9 and to prevent dust in the air from accumulating on the surfaces of the fixed plate 2 and the reduction motor 5. The wind blown by the fan blades 9 is directed toward the main body of the reduction motor 5 and blows toward the heat sink 12 on the outer surface of the main body of the reduction motor 5 through the opposite inclined surfaces on the left and right sides of the protective cover 6, and moves the moving mechanism. When the T-block 17 slides along the T-slot 20, the T-block 17 The two cross bars synchronously slide along the two grooves in the T-slot 20 and limit the T-block 17 to prevent the T-block 17 from deflecting and falling off during the movement. When the fan blades 9 rotate, the generated wind contacts the surface of the wind contact block 10, and due to the arc-shaped grooves on the wind contact block 10, the force area of ​​the wind contact is increased, so that the wind contact block 10 moves toward the heat sink 12, and synchronously drives the ring 11 to move toward the heat sink 12. When the fan blades 9 stop working, the second spring 18 pulls the T-block 17 to reset.
