Description

Technical Field

[0002] Mechanical limit motor is a technology widely used in various mechanical equipment. It is used to set the operating range of the motor when the motor starts to avoid machine failures caused by improper operation. This motor is widely used in various occasions that require precise position control and motion control, such as automation equipment, packaging machinery, logistics conveyor belts, wood processing equipment, etc. During the operation of the mechanical limit motor, the operation of each component will generate a large amount of heat energy. Therefore, a heat-dissipating rotating fan blade is connected to the rear end of the mechanical limit motor to blow external air into the motor housing and disperse the internal hot air flow to achieve a cooling effect. However, it is currently usually encountered in rainy days or in water-related operations that require driving, which is prone to splashing water and high air humidity. Working environment, so the air will contain a lot of moisture. Since the air contains a lot of moisture, the work of the rotating fan blades will blow the air containing moisture into the motor housing.

[0027] Example 1

[0028] Reference Figure 1 to Figure 5 , which is the first embodiment of the utility model, and this embodiment provides a waterproof mechanism for a mechanical limit motor. The waterproof mechanism for a mechanical limit motor includes a main component 100 and an adjustment component 200. Through the cooperation of the two, when encountering rainy days or when the operation needs to be driven and wading through water, the air containing a large amount of moisture can be filtered through the mutual cooperation of the extrusion plate 202b and the absorbent cotton 202c, ensuring that it can be used normally on rainy days or when the operation needs to be driven and wading through water, and will not cause damage to the internal components of the motor.

[0029] Specifically, the main assembly 100 includes a motor 101 , a base 102 and a rotating shaft 103 . The base 102 is fixed to the bottom of the motor 101 , and the rotating shaft 103 is rotatably connected to the motor 101 .

[0030] The motor 101 is used to drive the entire waterproof mechanism to work, and the base 102 is used to fix the position of the motor 101 to ensure that the motor 101 will not deviate when running. The start of the motor 101 can drive the rotating shaft 103 to rotate, so that the rotating shaft 103 can operate normally. The rotating shaft 103 is a prior art and will not be described in detail here.

[0031] The waterproof component 200 is disposed at the end of the motor 101 , and includes a rotating member 201 and a protective member 202 . The rotating member 201 is fixed to the end of the motor 101 , and the protective member 202 is disposed inside the rotating member 201 .

[0032] The rotating part 201 is used to filter the moisture contained in the air, ensuring that the moisture contained in the air is reduced when the air enters the motor, so that the inside of the motor is not damaged, the motor 101 can work normally, and the motor 101 can dissipate heat. The protective part 202 is used to protect the entire rotating part 201 from being hit by external forces, ensuring that the rotating part 201 can operate normally.

[0033] Specifically, the rotating member 201 includes a protective shell 201a and an air guide plate 201b. The protective shell 201a is fixed to the end of the motor 101, and the air guide plate 201b is fixed in the protective shell 201a.

[0034] The protective shell 201a is used to protect the air guide plate 201b from being hit by external forces and to fix the position of the rotating part 201. An air outlet is provided on one side of the protective shell 201a, and the air outlet is used to allow the hot air inside the motor 101 to be dissipated from the air outlet. The air guide plate 201b is used to disperse the airflow so that the motor 101 can be evenly cooled.

[0035] Specifically, the rotating member 201 further includes a fixed disk 201c and a rotating blade 201d. The fixed disk 201c is fixed to the surface of the rotating shaft 103, and the rotating blade 201d is fixed to the surface of the fixed disk 201c.

[0036] The fixed disk 201c is used to ensure that when the rotating shaft 103 rotates, the rotating fan blades 201d can be driven to rotate by the fixed disk 201c, and the rotating fan blades 201d are used to control the flow direction of the air sucked in during heat dissipation.

[0037] Specifically, the rotating member 201 further includes a buffer plate 201e and an air inlet plate 201f. The buffer plate 201e is fixed in the protective shell 201a, and the air inlet plate 201f is fixed in the buffer plate 201e.

[0038] The buffer plate 201e is used to isolate the noise generated by the rotating fan blade 201d when the rotating fan blade 201d rotates, and to protect the internal parts from damage to the greatest extent when the protective shell 201a is collided. The air inlet plate 201f is used to bring external air into the motor to cool the motor.

[0039] Example 2

[0040] Reference Figure 2 and Figure 4 , which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0041] Specifically, the rotating member 201 further includes a speed reducer 201g and a reciprocating roller 201h. The speed reducer 201g is located at the end of the rotating shaft 103, and the reciprocating roller 201h is fixed to the other end of the speed reducer 201g.

[0042] The output end of the reducer 201g is fixedly connected to the rotating shaft 103. The reducer 201g is used to reduce the speed of the rotating shaft 103, so that the reducer 201g can drive the reciprocating roller 201h to move slowly. The reciprocating roller 201h is a prior art and will not be described in detail here.

[0043] Specifically, the rotating member 201 further includes a positioning plate 201i and a positioning frame 201j. The positioning plate 201i is fixed to one side of the air inlet plate 201f, and the positioning frame 201j is fixed to the top of the positioning plate 201i.

[0044] The positioning plate 201i is used to ensure the position of the positioning frame 201j. There are two positioning frames 201j, both of which are mounted on both ends of the reciprocating roller 201h. The positioning frame 201j limits the position of the reciprocating roller 201h so that the reciprocating roller 201h can rotate in place.

[0045] Specifically, the rotating member 201 also includes a positioning column 201k, a sliding plate 201l, a rotating block 201m, a guide block 201n and a fixed rod 201o.

[0046] There are two positioning columns 201k, both fixed in the positioning frame 201j. The positioning column 201k is used to support the sliding plate 201l, and the sliding plate 201l is used to drive the fixed rod 201o to move. The rotating block 201m is used to drive the sliding plate 201l to move. The guide block 201n slides in the groove of the reciprocating roller 201h. When the reciprocating roller 201h rotates, it can drive the guide block 201n to move. The guide block 201n can drive the rotating block 201m to move. The rotating block 201m can drive the sliding plate 201l to move, so that the sliding plate 201l can drive the fixed rod 201o to move. When the guide block 201n moves to the end of the reciprocating roller 201h, the moving direction of the sliding plate 201l can be changed by the guide block 201n, so that the sliding plate 201l can reciprocate.

[0047] Example 3

[0048] Reference Figures 3 to 5 , which is the third embodiment of the utility model, and this embodiment is based on the first two embodiments.

[0049] Specifically, the protective member 202 includes a receiving plate 202a, an extrusion plate 202b and absorbent cotton 202c. The receiving plate 202a is fixed to one side of the air inlet plate 201f, the extrusion plate 202b is fixed to the end of the fixing rod 201o, and the absorbent cotton 202c is located inside the receiving plate 202a.

[0050] The receiving plate 202a is used to fix the position of the absorbent cotton 202c, and the squeezing plate 202b is used to squeeze the absorbent cotton 202c to ensure the absorbency of the absorbent cotton 202c. The absorbent cotton 202c is used to filter the moisture of the external air so that the external air cannot bring moisture into the motor.

[0051] Specifically, the protective member 202 further includes a positioning plate 202d and a protective cover 202e. The positioning plate 202d is fixed to one side of the receiving plate 202a, and the protective cover 202e is fixed inside the positioning plate 202d.

[0052] The positioning plate 202d is used to fix the position of the protective cover 202e. The protective cover 202e is used to prevent the absorbent cotton 202c from moving outward when it is squeezed by the squeezing plate 202b, ensuring that the squeezing plate 202b can squeeze the moisture inside the absorbent cotton 202c, thereby ensuring the normal function of the absorbent cotton 202c.

[0053] Specifically, the protective member 202 further includes a protective cover 202f and a drain pipe 202g. The protective cover 202f is fixed in the protective shell 201a, and the drain pipe 202g is disposed in the protective shell 201a.

[0054] An air inlet hole is provided on one side of the protective cover 202f so that the rotating fan blades 201d can draw external air into the motor to dissipate the heat of the motor. The drain pipe 202g runs through the protective shell 201a and the receiving plate 202a, and is used to remove moisture from the absorbent cotton 202c to ensure that there is no residual moisture in the receiving plate 202a and to ensure that air does not bring moisture into the motor.

[0055] During use, when it is necessary to dissipate heat inside the motor, first rotate the fan blades 201d to suck external air into the motor. When the air enters the motor, it comes into contact with the absorbent cotton 202c. The absorbent cotton 202c absorbs moisture in the air to ensure that no air containing moisture enters the motor. When the motor 101 rotates, the motor 101 drives the rotating shaft 103 to rotate, so that the rotating shaft 103 drives the reciprocating roller 201h to move through the reducer 201g, so that the extrusion plate 202b can squeeze the absorbent cotton 202c to ensure that the absorbent cotton 202c can effectively filter the moisture in the air. The moisture squeezed out of the absorbent cotton 202c can be discharged from the motor through the drain pipe 202g, ensuring that it can be used normally on rainy days or when the operation that needs to be driven is wading through water, and will not cause damage to the internal components of the motor.

[0056] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
