Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a dust-proof mechanism for a motor. Background Art

[0002] An electric motor is an electromagnetic device that converts or transmits electric energy according to the law of electromagnetic induction. Its main function is to generate driving torque. Therefore, electric motors are mainly used as power sources for electrical appliances or various machines. Electric motors can be divided into DC motors and AC motors according to the type of working power supply.

[0003] Motors are often used in processing equipment, and the environment in which the processing equipment is located usually contains a lot of dust. Dust entering the motor will have a negative impact on the operation of the motor. At this time, a motor dustproof mechanism is needed to effectively protect the motor.

[0004] After searching, it is proposed in a dustproof mechanism of a motor with patent publication number CN220673513U that "the dustproof mechanism of the motor is provided with a dustproof component on the base, so that the dust cover can cover the base under the action of the second spring, so as to protect the motor from dust when not in use; when the motor needs to be cooled after operation, the dust cover can be opened, and the plug rod can be inserted into the slot under the action of the first spring to position the dust cover; through the above arrangement, the motor can be protected from dust when not in use and the heat dissipation after the motor is in operation is not affected";

[0005] However, the above scheme still has certain shortcomings in actual use. The dust-proof component in this scheme can be flipped over to protect the motor from dust when not in use, and the dust-proof component is opened when the motor needs to dissipate heat after running. This dust-proof method is dispensable when the motor is in working state, which will cause the motor to be affected by dust in the working state, and then cause dust to enter the inside of the motor and have a negative impact on the operation of the motor.

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.

[0022] See also Figure 1-4 The utility model discloses a motor dustproof mechanism, including a base 1, a motor body 2 and a dustproof device 3 are arranged on the top of the base 1, a cleaning structure 4 is fixedly installed on the surface of the dustproof device 3, the dustproof device 3 includes a dustproof cover shell 301, a ventilation fan 304 is fixedly installed on the outer side of the dustproof cover shell 301, a dustproof net 305 is arranged on the outer side of the ventilation fan 304, the cleaning structure 4 includes a driving box 401, a turning handle 402 is rotatably connected to the outer side of the driving box 401, the turning handle 402 extends to the end of the movable end inside the driving box 401 and the inner wall of the driving box 401 are respectively fixedly connected and rotatably connected with a transmission shaft 403, the two transmission shafts 403 are connected by a transmission belt 404, the outer side of the transmission belt 404 A moving block 405 is connected via a soft rubber block, a moving bar 407 is sleeved on the outer side of the moving block 405, a cleaning brush 409 is fixedly connected to the outer side of the moving bar 407, and the cleaning brush 409 extends to the outside of the driving box 401. By arranging the dustproof device 3 and the cleaning structure 4, the motor body 2 can be wrapped therein by using the movable dustproof cover shell 301, so that the motor body 2 is protected in all directions, and the cleaning structure 4 can be used to periodically clean the dustproof net 305 on the outer side of the ventilation fan 304, so that the dustproof cover shell 301 can ensure the dustproof effect of the motor body 2 while allowing the gas inside and outside the dustproof cover shell 301 to circulate with each other, so as to ensure that the motor body 2 can effectively dissipate heat, so that the motor can be effectively protected both when idle and in working state.

[0023] Specifically, a front plate 302 is fixedly mounted on the front side of the dustproof cover shell 301 , and a rear cover 303 is movably plugged into the back side of the dustproof cover shell 301 .

[0024] In this embodiment, the through hole opened in the center of the front plate 302 can be used to extend the output shaft of the motor body 2 to the outside of the dust cover 301, and the rear cover 303 can be used to facilitate the opening and closing of the opening of the dust cover 301.

[0025] Specifically, a slide rail 306 is fixedly installed on the top of the base 1 , and the bottom end of the dust cover shell 301 is slidably connected to the surface of the slide rail 306 .

[0026] In this embodiment, the dustproof cover 301 can slide along the slide rail 306 , thereby improving the movement stability of the dustproof cover 301 .

[0027] Specifically, a notch is provided inside the moving bar 407 , and the size of the notch matches the size of the moving block 405 .

[0028] In this embodiment, since the moving block 405 slides with the inner wall of the moving bar 407, a relative position sliding occurs between the moving block 405 and the moving bar 407 during the movement of the moving block 405, so that the moving block 405 continues to slide in the recess of the moving bar 407, prompting the moving block 405 to drive the moving bar 407 to reciprocate on the surface of the cross bar 406.

[0029] Specifically, a cross bar 406 is fixedly installed on the inner wall of the driving box 401 , and a follower block 408 is fixedly connected to the end of the moving bar 407 , and the follower block 408 is slidably connected to the surface of the cross bar 406 .

[0030] In this embodiment, the follower block 408 can follow the moving bar 407 to slide along the surface of the crossbar 406 , thereby improving the movement stability of the moving bar 407 .

[0031] When in use, the dust cover 301 is pulled to make the dust cover 301 slide along the direction of the slide rail 306, so that the dust cover 301 gradually receives the motor body 2 therein, and then the rear cover 303 is pressed down to make the rear cover 303 close the opening of the dust cover 301, so that the motor body 2 is placed in the protective cavity formed between the dust cover 301 and the base 1, so that the motor body 2 is fully protected;

[0032] Furthermore, when the motor body 2 is in working state, the ventilation fan 304 can be started so that the ventilation fan 304 draws outside air into the interior of the dustproof cover 301, so that the ventilation fan 304 can effectively increase the heat dissipation speed of the motor when it is working, thereby improving the use effect of the motor;

[0033] When the dust net 305 needs to be cleaned, the handle 402 is turned so that the handle 402 drives the transmission belt 404 to rotate through the transmission shaft 403, and the transmission belt 404 drives the moving block 405 to reciprocate. Since the moving block 405 slides with the inner wall of the moving bar 407, the moving block 405 will slide relative to the moving bar 407 during its movement, so that the moving block 405 will continue to slide in the recess of the moving bar 407, prompting the moving block 405 to drive the moving bar 407 to reciprocate on the surface of the cross bar 406, causing the moving bar 407 to drive the cleaning brush 409 to scrape off the dust and impurities attached to the surface of the dust net 305, and the staff only needs to recycle the scraped impurities.

[0034] To sum up, the motor dustproof mechanism, by setting up a dustproof device 3 and a cleaning structure 4, can wrap the motor body 2 therein with a movable dustproof cover shell 301, so that the motor body 2 is protected in all directions, and the cleaning structure 4 can periodically clean the dustproof net 305 on the outside of the ventilation fan 304, so that the dustproof cover shell 301 can ensure the dustproof effect of the motor body 2 while allowing the gas inside and outside the dustproof cover shell 301 to circulate with each other, ensuring that the motor body 2 can effectively dissipate heat, so that the motor can be effectively protected both when idle and in working state.
