[0020] 4. PU wheels. Detailed Implementation

[0021] The embodiments of this utility model will be briefly described below with reference to the accompanying drawings.

[0022] Referring to Figures 2-5, a rapid assembly device for the wheels of a tabletop skateboard includes a base 1, on which a rotating mechanism 2 and a trimming mechanism 3 are provided. The rotating mechanism 2 is used to fix the PU wheel 4, and the trimming mechanism 3 is used to automatically remove residual glue from the end face and wheel surface of the PU wheel 4.

[0023] Referring to Figures 2-5, the rotating mechanism 2 includes a rotating platform 21 and a rotatable pressing block 26. The rotating platform 21 is rotatably mounted on the base 1, and the pressing block 26 is mounted above the rotating platform 21 and can move up and down. Specifically, a rotating motor 22 is installed inside the base 1. The rotating motor 22 is connected to the rotating platform 21. The rotating motor 22 drives the rotating platform 21 to rotate, which in turn drives the PU wheel 4 to rotate. The rotating mechanism 2 further includes a third adjusting component, which includes a third vertical slide rail 23 and a third vertical screw. The third vertical slide rail 23 is slidably mounted on a third base 24. The third vertical screw drives the third base 24 to move along the third vertical slide rail 23. A pressure block cylinder 25 is mounted on the third base 24. A pressure block 26 is rotatably mounted on the piston rod of the pressure block cylinder 25. After the PU wheel 4 is placed on the rotating table 21, the vertical height of the third base 24 is first adjusted by the third vertical screw. Then, the pressure block cylinder 25 pushes the pressure block 26 to press the PU wheel 4 down on the rotating table 21. When the rotating table 21 rotates, the pressure block 26 rotates together with the PU wheel 4, which serves to fix the PU wheel 4 on the rotating table 21 and make it rotate.

[0024] Referring to Figures 2-5, the trimming mechanism 3 includes a horizontal shaving blade 332 and a vertical blade 363. The horizontal shaving blade 332 is telescopically mounted on one side of the rotary table. Specifically, the trimming mechanism 3 further includes a first adjusting component, which includes a first vertical slide rail 31, a first vertical screw, a first horizontal slide rail 32, and a first horizontal screw. The first vertical screw drives the first horizontal slide rail 32 to move along the first vertical slide rail 31. The first horizontal slide rail 32 is slidably mounted on a first base 33. The first base 33 is equipped with a shaving cylinder 333 and a shaving slide rail 331. The horizontal shaving blade 332 is slidably mounted on the shaving slide rail 331. The piston rod of the shaving cylinder 333 is connected to the horizontal shaving blade 332. The first horizontal screw drives the first base 33 to move along the first horizontal slide rail 32. First, the vertical height of the first horizontal slide rail 32 is adjusted by the first vertical screw to ensure that the horizontal shaving blade 332 is at the same height as the residual adhesive on the end face of the PU wheel 4. Next, the first horizontal screw pushes the first base 33 closer to the rotary table 21. Finally, the shaving blade cylinder 333 pushes the horizontal shaving blade 332 along the shaving blade slide rail 331 to the position of the residual adhesive on the upper end face of the PU wheel 4. The rotating PU wheel 4 causes the residual adhesive to be cut off by the horizontal shaving blade 332, thus automatically removing the residual adhesive from the upper end face of the PU wheel 4. The adjustment is simple, the operation is convenient, and it can adapt to PU wheels 4 of different sizes.

[0025] Referring to Figures 2-5, the vertical blade 363 is movably mounted on the other side of the rotary table 21. Specifically, the trimming mechanism 3 also includes a second adjustment assembly, which includes a second vertical slide rail 34, a second vertical screw, a second horizontal slide rail 35, and a second horizontal screw. The second vertical screw drives the second horizontal slide rail 35 to move along the second vertical slide rail 34. The second horizontal slide rail 35 is slidably mounted on a second base 36. The second base 36 is equipped with a blade cylinder 361 and a blade slide rail 362. The vertical blade 363 is slidably mounted on the blade slide rail 362. The piston rod of the blade cylinder 361 is connected to the vertical blade 363. The second horizontal screw drives the second base 36 to move along the second horizontal slide rail 35. First, the position of the second horizontal slide rail 35 in the height direction is adjusted by the second vertical screw. Then, the second horizontal screw is controlled to adjust the second base 36 close to the PU wheel 4 on the rotary table 21. Finally, the vertical blade 363 is pushed close to the residual glue on the surface of the PU wheel 4 by the blade cylinder 361. The rotating PU wheel 4 causes the residual glue to fall off the wheel surface automatically, thus completing the removal of residual glue from the end face and the wheel surface of the PU wheel 4. The overall structure is simple and easy to adjust. It can be applied to PU wheels 4 of different sizes, has a fast production cycle, and is compatible with the use of various different sizes of wheels.

[0026] In addition, two start switch buttons 11 are installed on the base 1. The equipment can only be started by pressing both start switch buttons 11 at the same time, which avoids accidental injury to the operator and improves the safety of equipment use.

[0027] The above embodiments merely illustrate the implementation of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
