TECHNICAL FIELD

[0001] The utility model relates to electric roller technical field. BACKGROUND

[0002] The electric roller for conveying machine is fixedly installed at one end on the frame, and is connected with the cable and the frame at the other end. Figure 7 As shown in the figure, in the prior art, the cable end of the roller is detachably installed with the frame, and a threaded mounting shaft is generally arranged to pass through the cable from the mounting shaft, one end of the threaded mounting shaft is fixedly connected with the bearing seat assembly, and the other end is fixedly connected with the frame through threads.

[0003] The connection between the threaded mounting shaft and the frame needs to bear a certain radial force, and the electric roller is always in a rotating state, so that a certain vibration impact force is generated at the connection between the threaded mounting shaft and the frame. However, the threaded mounting shaft and the frame are in linear contact through threads, so that the stress of the contact surface between the threaded mounting shaft and the frame is relatively concentrated, and the threads are prone to damage; the electric roller is prone to damage and loosening at the connection with the frame after a long time of operation; if the threaded mounting shaft is loosened, it will rotate together with the electric roller, resulting in the breakage of the cable. In addition, static electricity is easily generated during transportation, which not only damages the electric roller and the goods, but also may cause a fire in a serious case; therefore, in actual use, it is found that the existing cable end installation mode of the electric roller has certain safety hazards, and the safety of the overall transportation equipment cannot be guaranteed.

[0004] Therefore, it is necessary to improve the electric roller mounting assembly, so that the installation process is more convenient, the cost is lower, and the installation stability can be improved. UTILITY MODEL CONTENTS

[0007] Further, the first mounting shaft of the electric roller is further provided with a sealing ring.

[0008] Further, the first mounting shaft of the electric roller is provided with a limiting tube for limiting the sealing ring, and the limiting tube is fixedly arranged in the first mounting shaft.

[0009] Furthermore, the electric roller has a threaded groove inside the first mounting shaft, a sealing ring is located at the end of the threaded groove, and the surface of the limiting tube is provided with threads that mate with the threaded groove.

[0012] Furthermore, the motor assembly of the electric drum includes a drive motor, a drive gear connected to the output shaft of the drive motor and cooperating with the inner wall of the drum, and the rotation of the drum is achieved by the rotation of the drive gear.

[0013] Furthermore, the end of the first mounting shaft of the electric roller that connects to the frame is a hexagonal prism with chamfered edges.

[0014] Beneficial Effects: Compared with the prior art, the advantages of this utility model are as follows: The electric roller adopts a first mounting shaft with a prismatic structure at the connection end with the frame, and is equipped with a conductive mounting sleeve to limit the installation position of both the electric roller and the frame. On the one hand, the prismatic structure of the first mounting shaft increases the contact area between the surface of the first mounting shaft and the frame, reduces stress concentration, improves the connection strength of the mounting components, and ensures the stability of the connection between the first mounting shaft and the frame. During high-intensity operation, the first mounting shaft will not rotate with the roller, thereby avoiding cable entanglement accidents. On the other hand, the conductive mounting sleeve on the first mounting shaft can maintain a certain distance between the frame and the bearing seat assembly of the electric roller, preventing friction between the frame and the first bearing, improving the bearing's life and load-bearing capacity. Furthermore, the conductive mounting sleeve has a certain conductivity, preventing static electricity from being generated during transportation, preventing static electricity from damaging the electric roller and the transported goods, preventing fire hazards, and improving the safety performance of the entire transportation process after the mounting components are assembled.
