Description

Technical Field

[0001] The utility model relates to the technical field of logistics equipment, in particular to an electric roller and a conveyor. Background Art

[0002] At present, electric rollers, as the main component of conveyors, are widely used in various transmission equipment for medium-sized box-type logistics.

[0003] When the electric drum in the related art rotates continuously, the local temperature rises quickly, and the temperature is concentrated in the area of ​​the reduction motor. Since the reduction motor and the drum body are generally in a non-contact relationship with a gap, the heat generated by the reduction motor needs to be transferred to the drum body through air for heat dissipation, and the heat dissipation efficiency is low. In addition, in order to control the temperature, the overall length of the motor is generally short, resulting in limited output power and torque of the motor. Utility Model Content

[0004] The embodiments of the utility model are intended to solve at least one of the technical problems existing in the prior art.

[0005] To this end, a first aspect of an embodiment of the utility model provides a motorized drum.

[0006] A second aspect of the embodiments of the present utility model provides a conveyor.

[0007] In view of this, according to the first aspect of an embodiment of the utility model, an electric drum is provided, which includes: a cylinder body, which is provided with an accommodating cavity; a motor assembly, which is arranged in the accommodating cavity and connected to the cylinder body; and a heat sink, which is arranged in the accommodating cavity and in contact with the motor assembly.

Specifically, the cylinder is provided with a receiving cavity, the motor assembly is arranged in the receiving cavity, and the motor assembly is connected to the cylinder, that is, the cylinder can rotate under the drive of the motor assembly.

Optionally, the driven member comprises a belt.

[0010] Specifically, driven by the motor assembly, the drum drives the belt to move through the transmission part to realize the transportation of items on the conveyor with the electric roller, which is widely used in medium-sized box-type logistics. It changes the transmission transportation mode of transporting items, medicines, blood samples, instruments, etc. through elevators, realizes transportation across floors or between buildings, alleviates the congestion of indoor passages and elevators, and improves transportation efficiency. It is understandable that medium-sized box-type logistics are widely used in hospital logistics, warehousing logistics, etc.

[0011] It is understandable that when the electric drum is running continuously, the temperature of the area where the motor assembly is located rises rapidly and the temperature is high. In addition, the heat dissipation is carried out by air conduction, and the heat dissipation efficiency is low, which affects the service life and performance of the electric drum.

[0012] The heat sink is arranged in the accommodating cavity, and the heat sink is in contact with the motor assembly. That is to say, when the electric drum is running continuously, the heat generated by the motor assembly can be conducted to the heat sink through the position where the heat sink contacts the motor assembly, and quickly dissipated, thereby significantly improving the heat dissipation effect, reducing the temperature of the area where the motor assembly is located, and extending the service life of the motor assembly and the electric drum.

[0013] In addition, the heat dissipation effect of the electric drum is improved by providing a heat sink, so the overall length of the motor assembly can be increased accordingly, while ensuring the heat dissipation effect of the electric drum, the output power and torque of the motor are increased, thereby improving the performance of the electric drum.

[0014] It can be understood that the motor assembly includes a motor, and the motor includes a rotor and a stator. Increasing the overall length of the motor assembly means lengthening the length of the rotor and the stator.

[0015] Optionally, the accommodating cavity includes a first area and a second area, the motor assembly is located in the first area, the second area is a cavity, and the heat sink is located in the cavity. When the motor assembly continues to run, the heat in the first area can be quickly transferred to the second area through the heat sink, thereby achieving rapid heat dissipation and improving heat dissipation efficiency.

[0022] In addition, while meeting the heat dissipation requirements, the overall length of the motor assembly can be increased, the output power and torque of the motor can be improved, and the performance of the electric drum can be improved.

It is understandable that metal material has good thermal conductivity, so when the electric roller is running continuously, the heat generated by the motor assembly can be quickly transferred to the heat sink and dissipated through the heat sink, thereby improving the heat dissipation efficiency of the electric roller, reducing the temperature rise in the area where the motor assembly is located, and extending the service life of the electric roller. At the same time, the overall length of the motor assembly can be increased, and the output power and torque of the motor can be improved while meeting the heat dissipation requirements.

[0025] In some technical solutions, optionally, the first metal member includes copper foil.

[0026] In this technical solution, the first metal part is limited to copper foil. It can be understood that copper foil has good thermal conductivity. Therefore, when the electric roller is running continuously, the heat generated by the motor assembly can be quickly transferred to the copper foil and dissipated through the copper foil, thereby improving the heat dissipation efficiency of the electric roller, reducing the temperature rise in the area where the motor assembly is located, and extending the service life of the electric roller.

[0027] At the same time, the overall length of the motor assembly can be increased, which can meet the heat dissipation requirements while increasing the output power and torque of the motor. The output power of the electric drum can be increased by about 60% at most.

[0028] In some technical solutions, optionally, the motor assembly includes a motor and a connecting piece, wherein the connecting piece is connected to the motor and to the inner wall of the cylinder, and the heat sink is in contact with the connecting piece; and the connecting piece includes a second metal piece.

[0034] Specifically, when the motor assembly is running continuously, the heat in the motor area can be quickly transferred to the cavity area where the heat dissipation body is located through the heat dissipation body and multiple contact parts, so that the heat can be quickly dissipated and the heat dissipation efficiency can be improved. Therefore, the length of the motor assembly can be increased accordingly, and the output power and torque of the motor assembly can be improved while ensuring the heat dissipation effect.

[0035] Optionally, the plurality of contact parts and the heat dissipation body are an integrated structure. It is understandable that the integrated structure is conducive to improving the heat transfer efficiency, thereby improving the heat dissipation efficiency of the electric roller.

[0041] Moreover, by adhering the heat sink to the inner wall of the cylinder through an adhesive, the heat sink can be reliably fixed, thereby preventing the cylinder from colliding with the heat sink during rotation and generating noise.

Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0057] Refer to the following Figure 1 and Figure 2 The electric drum 100 and the conveyor provided according to some embodiments of the present utility model are described.

[0058] In one embodiment according to the present application, Figure 1 and Figure 2 As shown, an electric drum 100 is proposed, which includes: a cylinder 110, which is provided with a receiving cavity 111; a motor assembly 120, which is arranged in the receiving cavity 111 and connected to the cylinder 110; and a heat sink 130, which is arranged in the receiving cavity 111 and contacts the motor assembly 120.

[0059] The electric drum 100 provided in the embodiment of the utility model includes a cylinder 110, a motor assembly 120 and a heat sink 130. Specifically, the cylinder 110 is provided with a accommodating cavity 111, the motor assembly 120 is arranged in the accommodating cavity 111, and the motor assembly 120 is connected to the cylinder 110, that is, the cylinder 110 can rotate under the drive of the motor assembly 120.

[0060] Optionally, the electric drum 100 further includes a first mounting portion 140 and a second mounting portion 150, which are respectively arranged at both ends of the drum 110 and are used for fixed installation, and the transmission portion 142 of the first mounting portion 140 is used to connect the driven member. Optionally, the driven member includes a belt.

[0061] Specifically, under the drive of the motor assembly 120, the cylinder 110 drives the belt to move through the transmission part 142 to realize the transportation of items by the conveyor with the electric roller 100, which is widely used in medium-sized box-type logistics. It changes the transmission transportation mode of transporting items, medicines, blood samples, instruments, etc. through elevators, realizes transportation across floors or between buildings, alleviates the congestion of indoor passages and elevators, and improves transportation efficiency. It is understandable that medium-sized box-type logistics are widely used in hospital logistics, warehousing logistics, etc.

[0062] It is understandable that when the electric drum 100 is running continuously, the temperature of the area where the motor assembly 120 is located rises quickly and is high, and the heat dissipation efficiency is low when air conduction is used for heat dissipation, which affects the service life and performance of the electric drum 100.

[0063] The heat sink 130 is disposed in the accommodating cavity 111, and the heat sink 130 is in contact with the motor assembly 120. That is to say, when the electric drum 100 is continuously running, the heat generated by the motor assembly 120 can be conducted to the heat sink 130 through the position where the heat sink 130 is in contact with the motor assembly 120, and quickly dissipated, thereby significantly improving the heat dissipation effect, reducing the temperature of the area where the motor assembly 120 is located, and extending the service life of the motor assembly 120 and the electric drum 100.

[0064] In addition, the heat dissipation effect of the electric drum 100 is improved by providing the heat sink 130 , so the overall length of the motor assembly 120 can be increased accordingly, while ensuring the heat dissipation effect of the electric drum 100 , the output power and torque of the motor 121 are increased, thereby improving the performance of the electric drum 100 .

[0074] In this embodiment, the heat sink 130 is defined as the first metal member, that is, the heat sink 130 is made of metal material. It is understandable that the metal material has good thermal conductivity, so when the electric drum 100 is running continuously, the heat generated by the motor assembly 120 can be quickly transferred to the heat sink 130 and dissipated through the heat sink 130, thereby improving the heat dissipation efficiency of the electric drum 100, reducing the temperature rise in the area where the motor assembly 120 is located, and extending the service life of the electric drum 100. At the same time, the overall length of the motor assembly 120 can be increased, and the output power and torque of the motor 121 can be improved while meeting the heat dissipation requirements.

[0075] In some embodiments, optionally, the first metal member includes copper foil.

[0076] In this embodiment, the first metal member is defined as copper foil. It can be understood that copper foil has good thermal conductivity. Therefore, when the electric drum 100 is running continuously, the heat generated by the motor assembly 120 can be quickly transferred to the copper foil and dissipated through the copper foil, thereby improving the heat dissipation efficiency of the electric drum 100, reducing the temperature rise in the area where the motor assembly 120 is located, and extending the service life of the electric drum 100.

[0083] In this embodiment, it is defined that the heat sink 130 includes a heat sink body 131 and a plurality of contact portions 132. Specifically, the plurality of contact portions 132 are spaced apart at one end of the heat sink body 131 facing the motor assembly 120. That is, the plurality of contact portions 132 are located between the heat sink body 131 and the motor assembly 120, that is, the heat sink body 131 and the motor assembly 120 are located in different areas within the accommodating cavity 111, wherein the heat sink body 131 is located in the cavity area of ​​the accommodating cavity 111.

[0084] Specifically, when the motor assembly 120 is continuously running, the heat in the area where the motor 121 is located can be quickly transferred to the cavity area where the heat dissipation body 131 is located through the heat dissipation body 131 and the multiple contact parts 132, so that the heat can be quickly dissipated and the heat dissipation efficiency can be improved. Therefore, the length of the motor assembly 120 can be increased accordingly, and the output power and torque of the motor assembly 120 can be improved while ensuring the heat dissipation effect.

[0085] Optionally, the plurality of contact portions 132 and the heat dissipation body 131 are an integrated structure.

Specifically, the first mounting portion 140 and the second mounting portion 150 are respectively arranged at both ends of the cylinder 110 and are used for fixed installation. The transmission portion 142 of the first mounting portion 140 is used to connect the driven member. Optionally, the driven member includes a belt.

[0097] Specifically, driven by the motor assembly 120, the cylinder 110 rotates, and drives the driven member to move through the transmission part 142, so as to realize the transportation of items by the conveyor with the electric roller 100, which is widely used in medium-sized box-type logistics. It changes the transmission transportation mode of transporting items, medicines, blood samples, instruments, etc. through elevators, realizes transportation across floors or between buildings, alleviates the congestion of indoor passages and elevators, and improves transportation efficiency. It is understandable that medium-sized box-type logistics are widely used in hospital logistics, warehousing logistics, etc.

[0098] In a specific embodiment, the electric drum 100 is composed of: a drum body (cylinder body 110), a bearing-type cover with grooves (first mounting part 140), a heat dissipation copper foil with a sticky surface (heat dissipation member 130), a motor support member (connecting member 122), a gear reduction motor (motor 121), and a bearing-type cover with a shaft (second mounting part 150).

[0099] The support member (connecting member 122) is pressed into the drum body (drum body 110) through a mold, and the gear reduction motor (motor 121) is inserted into one end of the formed drum body, and the heat dissipation copper foil (heat dissipation member 130) with a sticky surface is placed in the other end. The heat dissipation copper foil is adhered to the inner wall of the drum body through a special expansion pressing tool, and the bearing-type cover with an axis (second mounting part 150) and the bearing-type cover with a groove (first mounting part 140) are installed at both ends of the drum body, and the two ends of the drum body are pressed to complete the assembly.

[0100] The power and torque of the electric drum 100 are increased by lengthening the motor 121 (i.e. lengthening the rotor coil and lengthening the stator silicon steel sheet). At the same time, a heat dissipation copper foil is bonded to the inner wall of the left half of the drum body, and the heat is quickly transferred to the left half of the drum body, thereby doubling the heat dissipation effect.

[0101] According to a second aspect of the present invention, a conveyor is provided, comprising the electric roller 100 provided in any of the above embodiments, and thus having all the beneficial technical effects of the electric roller 100, which will not be described in detail herein.
