The clamping assembly includes a base plate, a fixed plate, a first turntable, a first motor, a moving plate, a pusher, a second turntable, a limiting frame, a handle, a positive and negative threaded screw, a centering block, a clamping plate, and a handle. The base plate is disposed on the worktable, and the fixed plate is located at one end of the base plate. The first turntable is disposed on the fixed plate. The output end of the first motor passes through the fixed plate and connects to the first turntable. The first turntable is also equipped with... The system includes a limiting frame with an open limiting cavity at the end away from the first turntable. Two sets of symmetrically arranged clamping plates are located within the limiting cavity. A centering groove is also provided at the center of the limiting frame near the first turntable. The centering groove contains the threaded screw and two sets of symmetrically arranged centering blocks. The centering blocks are threadedly connected to the threaded screw. The threaded screw passes through the limiting frame and is connected to the handle. The clamping plates are connected to the centering blocks. A movable plate is slidably mounted at the other end of the base plate. A pusher connected to the movable plate is mounted on the base plate. A second turntable is also mounted on the movable plate.

[0007] The workbench is also equipped with a feed assembly that drives the base plate to move;

[0008] The support assembly includes a bracket with a downward-opening C-shape, a roller frame, a bearing seat, and a nut. The two free ends of the bracket are fixed to the workbench. An L-shaped roller frame is also provided below the bracket. The roller frame is fitted with a bearing seat. The lower free end of the roller frame is also provided with an external thread. The nut is threadedly connected to the roller frame. The base plate is located between the two free ends of the bracket.

[0009] To facilitate stable feeding of the base plate, this utility model is improved by including a second motor, a threaded rod, and a slider in the feeding assembly. A groove is provided on the worktable, and the slider and the threaded rod are disposed in the groove. The slider is threadedly connected to the threaded rod. The output end of the second motor passes through the worktable and is connected to the threaded rod. The top of the slider is connected to the base plate.

[0010] To ensure the stability of the movement of the clamping plate, the present invention is improved by providing a guide rod at the end of the clamping plate away from the center of the positive and negative thread screws.

[0011] To ensure the stability of the moving plate, the present invention is improved by providing a guide groove on the base plate and a guide block that is slidably connected to the guide groove below the moving plate.

[0012] Preferably, the guide groove is inverted T-shaped.

[0013] Preferably, a gasket is also provided between the nut and the bearing housing.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides an automatic racket grip tape wrapping device, which has the following beneficial effects:

[0016] The automatic grip tape wrapping device for badminton rackets has a first turntable in the clamping assembly for fixing one end of the badminton racket, and a first motor that can precisely control its rotation angle to ensure that the racket rotates evenly when wrapping the grip tape.

[0017] The limiting frame and its internal clamping plates and centering blocks enable precise positioning and stable clamping of the racket. Rotating the handle drives the forward and reverse threaded screws, causing the two sets of centering blocks to move towards or away from each other, thereby adjusting the clamping plate spacing to accommodate rackets of different sizes. A guide rod located at the end of the clamping plate furthest from the center of the forward and reverse threaded screws ensures the stability of the clamping plate's movement, preventing deviation during clamping and further improving clamping accuracy.
