[0002] Existing roller motors include a roller and a power unit housed within the roller. Support frames are provided at both ends of the roller. However, existing rollers cannot directly traction the flipping component. For example, shared massage chairs in shopping malls have a front cover component at the front to ensure user privacy. However, the front cover component can affect the user's entry into the massage chair. Therefore, the front cover component is designed to be flippable. How the roller motor can traction the front cover component to achieve the flipping of the front cover component is a technical problem that needs to be solved. Summary of the Invention

[0003] The purpose of this invention is to provide a roller motor drive device. The driving force provided by the drive motor is reduced by a reduction mechanism to increase the torque and drive the roller to rotate in both directions, so as to wind and unwind the fabric roll, thereby realizing the traction and release of the flipping component.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a roller motor drive device includes a support frame, a roller, and a power unit. Two sets of support frames are provided and located at both ends of the roller. The roller is rotatably connected to the support frame through bearings. The power unit is housed inside the roller. The power unit includes a drive motor and a reduction mechanism that are axially connected as one unit. The drive motor is fixedly connected to one side of the support frame. The output end of the drive motor is drively connected to the input end of the reduction mechanism. A connecting block is fixedly connected to the output end of the reduction mechanism. The connecting block is fixedly connected to the roller. A strip groove is provided on the outer circumference of the roller. A pressure strip is detachably connected to the roller at the position corresponding to the strip groove. The pressure strip is used to fix one end of the rolled fabric to the roller. When the drive motor is driven, it can drive the roller to rotate forward and backward, thereby driving the rolled fabric to roll up and down.

[0005] Furthermore, a stepped portion is formed inside the roller, one end of the connecting block abuts against the stepped portion, the outer periphery of the connecting block is adapted to the inner wall of the roller, and the roller and the connecting block are fixedly connected as one unit by fasteners.

[0006] Furthermore, gaps are left between the drive motor and the roller, as well as between the reduction mechanism and the roller.

[0007] Furthermore, end caps are fixedly connected to both ends of the roller, and the end caps are rotatably connected to the support frame via bearings.

[0008] Furthermore, the support frame on the right side includes an integrally formed circular part and a cylindrical part, the drive motor is fixedly connected to the circular part, and the bearing is sleeved on the outer periphery of the cylindrical part.

[0009] Furthermore, a fixed connecting plate is provided at the right end of the drive motor, and the drive motor is fixedly connected to the annular part through the fixed connecting plate.

[0010] Furthermore, the strip groove extends from the left side of the roller to the right side of the roller, and the inner end of the strip groove has a flat portion. The pressure strip is connected to the strip groove by fasteners.
