Description

Technical Field

[0001] The utility model relates to a drying box motor structure capable of preventing damage by high temperature, belonging to the technical field of motor equipment. Background Art

[0002] Electroplating refers to the process of plating a layer of other metals or alloys on the surface of a workpiece using the principle of electrolysis. It can improve the wear resistance, reflectivity, and aesthetics of the workpiece, so it is widely used. After electroplating, the electroplating production line needs to use a drying oven to heat the surface of the workpiece to prevent the coating from being damaged by water vapor and carbon dioxide in the air, and at the same time, the hydrogen ions in the coating diffuse out of the coating during the heat preservation process to prevent hydrogen embrittlement of the plated parts.

[0003] At present, the drying boxes used in electroplating production lines all have external motors, and the output shaft of the motor is inserted into the drying box and directly connected to the high-temperature resistant wind wheel in the drying box. However, when the temperature of the drying box is too high, the output shaft of the motor will conduct heat, and this connection structure will cause the high temperature in the drying box to be directly transmitted to the motor through the motor output shaft connected to it, causing the motor to easily heat up and be damaged during the heat conduction process. Utility Model Content

[0004] The purpose of the utility model is to provide a drying box motor structure that prevents high-temperature damage. The structure separates the motor output shaft from the connecting shaft, so that the heat source of the connecting shaft will not be conducted to the motor output shaft, and will not be conducted from the motor output shaft to the motor, thereby preventing the motor from being damaged by heating up, extending the service life of the motor, and reducing the cost of multiple replacements. In addition, since the heat insulation pad provided by the coupling separates the first coupling seat from the second coupling seat, the heat insulation pad can achieve the function of isolating heat conduction, and the heat source in the first coupling seat will not be conducted to the second coupling seat, thereby preventing the heat in the connecting shaft from being ultimately conducted to the motor, thereby protecting the motor.

[0005] To achieve this purpose, the utility model adopts the following technical solutions:

[0006] The utility model provides a drying box motor structure for preventing high temperature damage, comprising:

[0007] include:

[0008] Motor;

[0010] A wind wheel connected to the connecting shaft;

[0011] a motor output shaft, drivingly connected to the motor; and

[0012] A coupling, connecting the motor output shaft and the connecting shaft;

[0013] Wherein, the coupling is provided with a heat insulation pad for isolating heat conduction between the motor output shaft and the connecting shaft.

[0014] In one embodiment of the present invention, the coupling comprises:

[0015] A first coupling seat connected to the connecting shaft; and

[0016] A second coupling seat connected to the output shaft of the motor;

[0017] Wherein, the thermal insulation pad is connected between the first coupling seat and the second coupling seat which are opposite to each other.

[0018] In one implementation manner of the present utility model, the first coupling seat is not in contact with the second coupling seat, and the motor output shaft is not in contact with the connecting shaft.

[0019] In one embodiment of the utility model, the first coupling seat includes a first coupling portion synchronously rotatably connected to the connecting shaft and a first docking portion connected to the first coupling portion, and a plurality of first protrusions are provided on the side of the first docking portion facing the second coupling seat, and a plurality of first grooves are formed between the plurality of first protrusions.

[0020] In one embodiment of the utility model, the second coupling seat includes a second coupling portion connected to the motor output shaft for synchronous rotation and a second docking portion connected to the second coupling portion, and a plurality of second protrusions are provided on the side of the second docking portion facing the first coupling seat, and a plurality of second grooves are formed between the plurality of second protrusions.

[0021] In one embodiment of the utility model, a plurality of third protrusions are provided on the outer periphery of the thermal insulation pad, and a plurality of third grooves are formed between the third protrusions; wherein the third protrusions are embedded in the correspondingly arranged first grooves and the second grooves, and the first protrusions and the second protrusions are arranged correspondingly and embedded in the third grooves.

[0026] In one embodiment of the present invention,

[0027] The beneficial effects of the utility model are:

[0028] The utility model provides a drying box motor structure for preventing damage due to high temperature, which connects the motor output shaft and the connecting shaft respectively through a coupling. When the motor drives the motor output shaft to rotate, the connecting shaft is driven to rotate synchronously through the coupling, and then the wind wheel located inside the drying box can be driven to rotate. Due to the isolation design of the motor output shaft and the connecting shaft, the heat source of the connecting shaft will not be transmitted to the motor output shaft, and will not be transmitted from the motor output shaft to the motor, thereby avoiding the motor from heating up and being damaged, extending the service life of the motor, and reducing the cost of multiple replacements. In addition, since the heat insulation pad provided by the coupling isolates the first coupling seat from the second coupling seat, the heat insulation pad achieves the function of isolating heat conduction, and the heat source in the first coupling seat will not be transmitted to the second coupling seat. When the drying box is working at high temperature, even if the high temperature in the drying box is conducted to the connecting shaft in the drying box, and then the connecting shaft conducts the heat to the first coupling seat, due to the heat-isolating and heat-conducting effect of the thermal insulation pad, the heat source of the first coupling seat is isolated outside the thermal insulation pad and will not be conducted to the second coupling seat, thereby preventing the heat in the connecting shaft from eventually being conducted to the motor, thereby protecting the motor.

[0037] like Figure 1-4 As shown, this embodiment provides a drying box motor structure that prevents high-temperature damage, and the drying box motor structure includes: a motor 1; a connecting shaft 7; a wind wheel 6, connected to the connecting shaft 7; a motor output shaft 11, drivingly connected to the motor 1; and a coupling 2, connecting the motor output shaft 11 and the connecting shaft 7; wherein the coupling 2 is provided with a thermal insulation pad 3 for isolating heat conduction between the motor output shaft 11 and the connecting shaft 7.

[0038] In some embodiments, the coupling 2 includes: a first coupling seat 21 connected to the connecting shaft 7; and a second coupling seat 22 connected to the motor output shaft 11; wherein the thermal insulation pad 3 is connected between the first coupling seat 21 and the second coupling seat 22 which are connected to each other.

[0039] The second coupling seat 22 drives the first coupling seat 21 to rotate through the heat insulation pad 3 , thereby enabling the motor output shaft 11 to drive the connecting shaft 7 to rotate.

[0040] In some embodiments, the first coupling seat 21 does not contact the second coupling seat 22 , and the motor output shaft 11 does not contact the connecting shaft 7 .

[0041] The drying box motor structure provided in this embodiment is connected to the motor output shaft 11 and the connecting shaft 7 respectively through the coupling 2. When the motor 1 drives the motor output shaft 11 to rotate, the connecting shaft 7 is driven to rotate synchronously through the coupling 2, and then the wind wheel 6 located inside the drying box can be driven to rotate. Due to the isolation design of the motor output shaft 11 and the connecting shaft 7, the heat source of the connecting shaft 7 will not be conducted to the motor output shaft 11, and will not be conducted from the motor output shaft 11 to the motor 1, thereby avoiding the motor 1 from heating up and being damaged, extending the service life of the motor 1, and reducing the cost of multiple replacements. In addition, since the heat insulation pad 3 provided by the coupling 2 isolates the first coupling seat 21 from the second coupling seat 22, the heat insulation pad 3 realizes the function of isolating heat conduction, and the heat source in the first coupling seat 21 will not be conducted to the second coupling seat 22. When the drying box is in the high-temperature working state, even if the high temperature in the drying box is conducted to the connecting shaft 7 in the drying box, and then the connecting shaft 7 conducts the heat to the first coupling seat 21, due to the heat-isolating and heat-conducting effect of the thermal insulation pad 3, the heat source of the first coupling seat 21 is isolated outside the thermal insulation pad 3 and will not be conducted to the second coupling seat 22, thereby preventing the heat in the connecting shaft 7 from being ultimately conducted to the motor 1, thereby protecting the motor 1.

[0042] In some embodiments, the first coupling seat 21 includes a first coupling portion 211 synchronously rotatably connected to the connecting shaft 7 and a first docking portion 212 connected to the first coupling portion 211, and the first docking portion 212 is provided with a plurality of first protrusions 214 on the side facing the second coupling seat 22, and a plurality of first grooves 213 are formed between the plurality of first protrusions 214.

[0044] In some embodiments, the second coupling seat 22 includes a second coupling portion 221 that is synchronously rotated with the motor output shaft 11 and a second docking portion 222 that is connected to the second coupling portion 221, and the second docking portion 222 is provided with a plurality of second protrusions 224 on the side facing the first coupling seat 21, and a plurality of second grooves 223 are formed between the plurality of second protrusions 224.

[0045] Optionally, the second coupling portion 221 is a cylindrical structure and is sleeved outside the motor output shaft 11 , and the second coupling portion 221 and the motor output shaft 11 are connected via a key; the second docking portion 222 is a disc-shaped structure.

[0046] In some embodiments, a plurality of third protrusions 32 are provided on the periphery of the thermal insulation pad 3, and a plurality of third grooves 31 are formed between the third protrusions 32; wherein the third protrusions 32 are embedded in the correspondingly arranged first grooves 213 and the second grooves 223, and the first protrusions 214 and the second protrusions 224 are correspondingly arranged and embedded in the third grooves 31.

[0047] In this embodiment, the upper end of the third protrusion 32 of the thermal insulation pad 3 is embedded in the first groove 213 of the first coupling seat 21, and the lower end of the third protrusion 32 of the thermal insulation pad 3 is embedded in the second groove 223 of the second coupling seat 22; at the same time, the first protrusion 214 of the first coupling seat 21 is embedded in the upper part of the third groove 31 of the thermal insulation pad 3, and the second protrusion 224 of the second coupling seat 22 is embedded in the lower part of the third groove 31 of the thermal insulation pad 3. That is, the first protrusions 214 of the first coupling seat 21 and the second protrusions 224 of the second coupling seat 22 are arranged one by one opposite to each other and are respectively embedded in the third grooves 31, and the first grooves 213 of the first coupling seat 21 and the second grooves 223 of the second coupling seat 22 are arranged one by one opposite to each other and are embedded in the third grooves 31. Thus, the protrusions and grooves of the heat insulation pad 3 are respectively arranged corresponding to the grooves and protrusions of the coupling seat, so that the heat insulation pad 3 drives the second coupling seat 22 to rotate synchronously with the first coupling seat 21. In addition, the heat insulation pad 3 plays a role in isolating heat conduction, isolating the heat source in the first coupling seat 21 outside the heat insulation pad 3, so that the heat source cannot be conducted to the second coupling seat 22, thereby protecting the motor 1 and preventing the motor 1 from heating up and being damaged.

[0048] In some embodiments, a support member 5 connected to the motor 1 is further included. The support member 5 is connected to the motor 1 via a plurality of connecting members 4 , and the coupling 2 is located in the plurality of connecting members 4 .

[0049] In this embodiment, the end surface of the motor 1 is fixedly connected to the support member 5 via the connecting member 4, and the support member 5 is used to be fixedly connected to the body of the drying box, so as to fix the motor structure on the drying box.

[0050] In some embodiments, the support member 5 is fixedly connected to a fixing seat 8 , and the connecting shaft 7 is rotatably disposed in the fixing seat 8 .
