[0025] Figure 1 A schematic diagram of an electric roller 100 according to an embodiment of the present invention is shown. Figure 2 An exploded view of an electric roller 100 according to an embodiment of the present invention is shown below, in conjunction with... Figure 1 and Figure 2 Provide a detailed description.

[0026] like Figure 1 and Figure 2 As shown, the electric roller 100 includes a cylinder 110, an end cap 120, and a drive unit 130. The cylinder 110 is configured as a hollow structure, having an internal cavity 111 for mounting components such as the drive unit 130. The cylinder 110 includes a main body portion 112 and a connecting portion 113 arranged sequentially along a first direction. The main body portion 112 can be used to cooperate with the belt of a belt conveyor, and the connecting portion 113 can be used to pivotally mount the electric roller 100 onto the frame of the belt conveyor. Specifically, a bearing can be installed on the connecting portion 113, which allows the connecting portion 113 (electric roller 100) to be pivotally fitted into a pre-set hole on the frame, achieving precise connection and flexible rotation between the electric roller 100 and the frame. Preferably, the outer diameter of the connecting part 113 is smaller than the outer diameter of the main body 112, thereby forming a shoulder 114 between the connecting part 113 and the main body 112. The shoulder 114 can accurately position the bearing, thereby significantly reducing the possibility of axial sway during the rotation of the electric roller 100 and effectively improving the stability and reliability of the electric roller 100.

[0027] A first opening 115 is provided at the end of the connecting portion 113 away from the main body 112 (i.e., the first end of the cylinder 110), and the first opening 115 communicates with the internal cavity 111 of the cylinder 110. A drive unit 130 is detachably disposed within the internal cavity 111 of the cylinder 110, and an end cap 120 is detachably connected to the first end of the cylinder 110 and substantially covers the first opening 115. A central hole 121 is provided on the end cap 120. The drive unit 130 includes a fixed shaft 131, which passes through the central hole 121 through the end cap 120 and extends outside the cylinder 110. Furthermore, the drive unit 130 is configured to pass through the first opening 115, allowing the user to disassemble, repair, or replace the drive unit 130 simply by removing the end cap 120 from the electric roller 100. The entire process does not require adjustment of the belt tension, effectively reducing operational steps and avoiding the need to replace the entire electric roller 100, thereby effectively reducing maintenance difficulty and cost.

[0028] According to one embodiment of the present invention, such as Figure 2 As shown, the drive device 130 may further include a motor 132. The motor 132 serves as the core power component of the drive device 130, responsible for outputting power and driving the electric roller 100 to rotate. In some embodiments, the housing portion of the motor 132 is fixedly connected to the fixed shaft 131, and the output shaft of the motor 132 serves as the output shaft of the drive device 130. In these embodiments, the motor 132 directly drives the cylinder 110 to rotate, which simplifies the drive structure of the electric roller 100 and improves rotation efficiency. Furthermore, in other embodiments (e.g.) Figure 2 In the illustrated embodiment, the drive device 130 may further include a reducer 133, wherein the output shaft of the motor 132 is connected to the input shaft of the reducer 133 (e.g., via a coupling), and correspondingly, the output shaft of the reducer 133 serves as the output shaft of the drive device 130. In these embodiments, the motor 132 drives the reducer 133, and the reducer 133 then drives the cylinder 110 to rotate. The reducer 133 can reduce the speed of the motor 132 while increasing the output torque, enabling the electric roller 100 to drive the load more powerfully.

[0029] According to one embodiment of the present invention, such as Figure 2 As shown, the electric roller 100 also includes a fixing member 140, which is installed in the internal cavity 111 of the cylinder 110. The drive device 130 is inserted into the fixing member 140 to achieve a stable connection and transmission between the drive device 130 and the cylinder 110, while ensuring that the drive device 130 is easy to disassemble.

[0030] Specifically, the fastener 140 can be non-removably fixed inside the cylinder 110 by welding, bonding, or other connection methods, or it can be detachably fixed inside the cylinder 110 by snap-fit ​​connections, bolt connections, or other connection methods. For example, Figure 3 A schematic diagram of a fastener 140 according to one embodiment of the present invention is shown. Figure 2 and Figure 3 In the embodiment shown, a plurality of first threaded holes 141 are provided on the outer periphery of the fastener 140, and a plurality of first through holes 116 are provided on the side wall of the cylinder 110 (main body 112). Each first through hole 116 is equipped with a screw 150. The screw 150 passes through the first through hole 116, passes through the cylinder 110, and is screwed into the corresponding first threaded hole 141, thereby achieving a stable connection between the cylinder 110 and the fastener 140.

[0031] Additionally, a spline groove 142 is provided on the side of the fixing member 140 facing the driving device 130, and a spline 134 is provided on the output shaft of the driving device 130. The spline 134 is inserted into the spline groove 142, thereby realizing the transmission connection between the cylinder 110 and the driving device 130, allowing the driving device 130 to drive the cylinder 110 to rotate. Those skilled in the art will readily understand that in some embodiments, a spline can also be provided on the side of the fixing member 140 facing the driving device 130, and a spline groove 142 can be provided on the output shaft of the driving device 130. This also achieves the transmission connection between the cylinder 110 and the driving device 130, allowing the driving device 130 to drive the cylinder 110 to rotate. In addition, in other embodiments, the fastener 140 and the output shaft of the drive device 130 can also be connected by a key connection, a semi-circular key connection, or a non-circular shaft hole connection (for example, the output shaft of the drive device 130 is a hexagonal shaft, and the fastener 140 is provided with a hexagonal hole accordingly), which is also within the protection scope of this utility model.

[0032] Figure 4 A schematic diagram of an end cap 120 according to an embodiment of the present invention is shown. Figure 4 As shown, the end cap 120 may include a first part 122 and a second part 123, wherein both the first part 122 and the second part 123 are configured as annular structures, particularly as circular annular structures, the first part 122 is connected to one side of the second part 123, and the outer diameter of the first part 122 is smaller than the outer diameter of the second part 123. Figure 5a An assembly diagram of the cylinder 110 and end cap 120 according to an embodiment of the present invention is shown. Figure 5b A schematic diagram of a cylinder 110 and an end cap 120 according to an embodiment of the present invention is shown. Figure 4 , Figure 5a and Figure 5bAs shown, the first part 122 of the end cap 120 is inserted into the cylinder 110 (connecting part 113) through the first opening 115 and mates with the inner wall of the cylinder 110. This helps improve the installation accuracy of the end cap 120, reduces the possibility of radial wobbling of the end cap 120, and ensures that the end cap 120 and the fixed shaft 131 can rotate stably relative to each other. The second part 123 of the end cap 120 mates with the end face of the first end of the cylinder 110 and is connected to the cylinder 110 by screws. This allows the end cap 120 to be stably fixed to the cylinder 110 and is easy to disassemble. In addition, the end cap 120 and the cylinder 110 can also be connected by snap-fit, threaded connection, pin connection, or tenon and mortise connection.

[0033] According to one embodiment of the present invention, such as Figure 5a As shown, the inner wall of the cylinder 110 is provided with a mounting surface 117. This mounting surface 117 can be formed by high-precision machining (e.g., grooving) inside the cylinder 110, and its position is adjacent to the end face of the first end of the cylinder 110 (i.e., close to the first opening 115). Correspondingly, an annular protrusion 124 is provided on the outer periphery of the first part 122 of the end cap 120, and this annular protrusion 124 mates with the mounting surface 117 of the cylinder 110. By adopting this design, the fitting accuracy between the end cap 120 and the cylinder 110 can be further improved, the connection stability between the end cap 120 and the cylinder 110 can be improved, and the end cap 120 can be less prone to radial wobbling.

[0034] According to one embodiment of the present invention, such as Figure 5a As shown, a sealing structure is provided between the cylinder 110 and the end cap 120. The sealing structure can be, for example, a sealing ring 160, which is detachably fitted onto the outside of the first part 122 of the end cap 120 and located between the annular protrusion 124 and the second part 123. The outer edge of the sealing ring 160 is in close contact with the inner wall (assembly surface 117) of the cylinder 110, effectively preventing external oil, water, dust, and other debris from entering the cylinder 110, keeping the interior of the cylinder 110 clean, providing a good working environment for components such as the drive device 130, and extending the service life of the electric roller 100. Optionally, the sealing ring 160 can be a rubber sealing ring, a polyurethane sealing ring, or a silicone sealing ring, etc. In other embodiments, the sealing structure can also employ a labyrinth seal or other sealing methods.

[0035] Figure 6 An assembly diagram of the drive device 130 and end cap 120 according to an embodiment of the present invention is shown. Figure 6As shown, the inner diameter of the first part 122 of the end cap 120 is smaller than the inner diameter of the second part 123, thus making the central hole 121 stepped (stepped hole). A first bearing 170 is provided between the first part 122 of the end cap 120 and the fixed shaft 131. The first bearing 170 can significantly reduce the wear of the end cap 120, making the rotation of the cylinder 110 and the end cap 120 smoother, while also effectively reducing noise and improving the operating efficiency and reliability of the electric roller 100. Preferably, the inner ring of the first bearing 170 abuts against the shoulder on the fixed shaft 131, and the outer ring of the first bearing 170 abuts against the step in the central hole 121.

[0036] According to one embodiment of the present invention, such as Figure 2 As shown, a second opening (not shown) is provided at the end of the main body 112 away from the connecting part 113 (i.e., the second end of the cylinder 110), and the second opening communicates with the internal cavity 111 of the cylinder 110. The electric roller 100 also includes a stepped shaft head 180, the larger diameter portion of which is inserted into the internal cavity 111 of the cylinder 110 through the second opening. The smaller diameter portion is used to pivotally mount the electric roller 100 on the frame of the belt conveyor. Specifically, a bearing can be installed on this portion, and the shaft head (electric roller 100) can be pivotally fitted into a pre-set hole on the frame, achieving precise connection and flexible rotation of the electric roller 100 to the frame.

[0037] Figure 7 A schematic diagram of an installation structure 200 according to an embodiment of the present invention is shown. Figure 8 A cross-sectional view of an installation structure 200 according to an embodiment of the present invention is shown below, in conjunction with... Figure 7 and Figure 8 Provide a detailed description.

[0038] like Figure 7 and Figure 8As shown, the mounting structure 200 mainly focuses on the mounting of the first end of the electric roller 100, and includes a support member 210, a connector 220, a second bearing 230, and the electric roller 100. The support member 210 can be the frame of mechanical equipment (e.g., a belt conveyor) or other support structure. A mounting hole 211 is provided on the support member 210; preferably, the mounting hole 211 is designed as a stepped hole. The second bearing 230 is mounted on the connecting portion 113 of the cylinder 110 of the electric roller 100, and the connecting portion 113 of the cylinder 110 is pivotally mounted in the mounting hole 211 via the second bearing 230. The inner ring of the second bearing 230 abuts against a shoulder 114 on the cylinder 110, and the outer ring of the second bearing 230 abuts against a step in the stepped hole. Furthermore, the connector 220 is fixedly connected between the support member 210 and the fixed shaft 131. When the drive unit 130 is working, the cylinder 110 and the end cover 120 will rotate around the fixed shaft 131. When the drive unit 130 malfunctions, the user only needs to remove the connector 220, the end cover 120, and the drive unit 130 in sequence to disassemble, repair, or replace the drive unit 130, which effectively reduces the number of operation steps and avoids replacing the entire electric roller 100, thereby effectively reducing maintenance difficulty and cost.

[0039] Figure 9 A schematic diagram of a belt conveyor 300 according to an embodiment of the present invention is shown below, in conjunction with... Figure 9 Provide a detailed description.

[0040] like Figure 9 As shown, the belt conveyor 300 includes a belt 310, an electric roller 100, and a driven roller 320. The belt 310 is wound around the electric roller 100 and the driven roller 320, and the electric roller 100 can drive the belt 310 to rotate in a preset direction.

[0041] Compared with the prior art, the embodiments of this utility model provide an electric roller 100, an installation structure 200 and a belt conveyor 300, which allows users to replace or repair the internal components of the electric roller 100 without adjusting the belt tension, effectively reducing the number of operation steps, avoiding the need to replace the entire electric roller, and reducing maintenance difficulty and cost.

[0042] Although the above mainly introduced the application of electric rollers in belt conveyors, the application scope of the electric roller of this invention is not limited to belt conveyors. It can also be applied to other mechanical equipment such as chain conveyors, printing presses, packaging machines, and textile machinery.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
