Description

Technical Field

[0001] This utility model relates to the field of table tennis ball serving machine technology, and in particular to a ball feeding wheel trimming mechanism for an automatic table tennis ball serving machine. Background Technology

[0002] A table tennis ball serving machine is a comprehensive device combining electronic, mechanical, and computer technologies, primarily used for table tennis training and recreation. It launches the ball by rubbing it against a friction wheel controlled by a DC motor, giving the ball initial velocity. Table tennis ball serving machines are characterized by high automation, high sensitivity, and reliable stability. They can launch balls of various types and are suitable for table tennis enthusiasts of different skill levels.

[0003] The table tennis ball serving machine needs to be equipped with a ball feed dial to facilitate continuous ball feeding. The ball feed dial is an injection molded part. Due to the influence of manufacturing process and injection pressure, a certain amount of flash will form in the parting surface area. The flash on the edge of the ball feed hole of the ball feed dial must be effectively treated, otherwise it will affect the normal ball feeding. The existing trimming mechanism requires workers to hold the ball feed dial by hand to trim the edge, and can only process one ball feed hole at a time. This is not only inefficient, but also difficult to control the trimming depth, resulting in inconsistent trimming results. Utility Model Content

[0004] This utility model addresses the deficiencies in the existing technology by providing a ball feeding wheel trimming mechanism for an automatic table tennis ball serving machine.

[0005] This utility model is achieved through the following technical solution:

[0006] An automatic table tennis ball serving machine ball feed wheel trimming mechanism includes a limiting mechanism, a feed wheel, a trimming mechanism, and a handle. The feed wheel is locked at the top of the limiting mechanism, the trimming mechanism is locked at the top of the limiting mechanism, and the handle is locked at the top of the trimming mechanism. The trimming mechanism includes a mounting plate, a connecting rod, a drive gear, a limiting sleeve, a movable ring, a driven gear, a mounting ring, and a trimming wheel. The connecting rod is movably disposed in the middle of the mounting plate. The drive gear is fixed to the outside of the connecting rod. The limiting sleeve is fixedly disposed at the bottom of the mounting plate. The movable ring is movably connected to the outside of the limiting sleeve. The driven gear is fixedly connected to the outside of the movable ring. The mounting ring is fixedly disposed at the bottom of the movable ring. The trimming wheel is sleeved and fixedly fixed to the outside of the mounting ring.

[0007] In a preferred embodiment of the present invention, the limiting mechanism includes a base, a limiting ring, and a limiting rod. The limiting ring is fixedly disposed on the upper surface of the base, and the limiting rod is fixedly disposed on the upper surface of the base and disposed in the middle of the limiting ring.

[0008] The limiting mechanism is mainly used to limit the installation of the dial wheel and ensure that the installation position of the top trimming mechanism corresponds to the processing position of the dial wheel.

[0009] In a preferred embodiment of this utility model, the position of the limiting ring corresponds to the position of the ball hole on the surface of the dial wheel, and the outer side of the limiting ring is engaged with the inner side of the ball hole on the surface of the dial wheel.

[0010] The limiting ring is locked inside the ball-handling hole to effectively limit the movement of the ball-handling wheel, ensuring that the trimming wheel of the trimming mechanism contacts the inner top of the ball-handling hole.

[0011] In a preferred embodiment of this utility model, the fixed position of the limiting sleeve corresponds to the position of the limiting rod, the limiting sleeve is disposed on the outer side of the top of the limiting rod, and a locking hole is provided at its bottom to cooperate with the limiting rod.

[0012] The limiting sleeve of the trimming mechanism is fitted onto the top of the limiting rod of the limiting mechanism to achieve the positioning of the trimming mechanism. The depth of the locking hole at the bottom of the limiting sleeve is fixed, thereby fixing the depth of the trimming wheel locked in the ball hole.

[0013] In a preferred embodiment of this utility model, the driving gear meshes with the driven gear, and the top of the connecting rod is provided with a socket that mates with the handle;

[0014] Crank the handle to control the connecting rod to rotate, which in turn drives the driven gear to rotate, causing the trimming wheel to rotate and effectively polish the top of the ball hole of the dial wheel.

[0015] In a preferred embodiment of this utility model, the outer side of the trimming wheel is inclined, and the vertical cross-section of the trimming wheel is an isosceles trapezoidal structure.

[0016] The beneficial effects of this utility model are:

[0017] The automatic table tennis ball serving machine's ball feeding wheel trimming mechanism effectively limits and positions the ball feeding wheel. After rotating the handle, the trimming wheel rotates synchronously via gear drive, allowing for rapid grinding of the inner top of the ball feeding hole on the wheel. Multiple ball feeding holes are processed simultaneously, ensuring effective frizz removal while significantly increasing processing speed. Attached Figure Description

[0023] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0024] like Figure 1-4 The table tennis automatic ball serving machine shown includes a ball feeding wheel trimming mechanism, comprising a limiting mechanism 1, a dial 2, a trimming mechanism 3, and a handle 4. The dial 2 is secured to the top of the limiting mechanism 1, the trimming mechanism 3 is secured to the top of the limiting mechanism 1, and the handle 4 is secured to the top of the trimming mechanism 3. The trimming mechanism 3 includes a mounting plate 31, a connecting rod 32, a drive gear 33, a limiting sleeve 34, a movable ring 35, a driven gear 36, a mounting ring 37, and a trimming wheel 38. The connecting rod 32 is movably disposed in the middle of the mounting plate 31. The drive gear 33 is fixed to the outside of the connecting rod 32. The limiting sleeve 34 is fixedly disposed at the bottom of the mounting plate 31. The movable ring 35 is movably connected to the outside of the limiting sleeve 34. The driven gear 36 is fixedly connected to the outside of the movable ring 35. The mounting ring 37 is fixedly disposed at the bottom of the movable ring 35. The trimming wheel 38 is sleeved and fixedly fixed to the outside of the mounting ring 37.

[0025] Specifically, the limiting mechanism 1 includes a base 11, a limiting ring 12, and a limiting rod 13. The limiting ring 12 is fixedly disposed on the upper surface of the base 11, and the limiting rod 13 is fixedly disposed on the upper surface of the base 11 and disposed in the middle of the limiting ring 12. The position of the limiting ring 12 corresponds to the position of the ball hole on the surface of the dial wheel 2. The outer side of the limiting ring 12 is locked inside the ball hole on the surface of the dial wheel 2. The fixed position of the limiting sleeve 34 corresponds to the position of the limiting rod 13. The limiting sleeve 34 is disposed on the outer side of the top of the limiting rod 13, and its bottom has a locking hole that cooperates with the limiting rod 13. The drive gear 33 meshes with the driven gear 36. The top of the connecting rod 32 has a insertion hole that cooperates with the handle 4. The outer side of the trimming wheel 38 is inclined, and the vertical section of the trimming wheel 38 has an isosceles trapezoidal structure.

[0026] In this embodiment, the dial 2 is first installed effectively, and the ball hole of the dial 2 is fitted onto the outside of the limiting ring 12 of the base 11. The bottom of the dial 2 is in contact with the upper surface of the base 11, and the top of the limiting ring 12 is lower than the top of the ball hole. Then, the trimming mechanism 3 is installed, and the limiting sleeve 34 is fitted onto the top of the limiting rod 13. Due to defects such as burrs and flash on the inner side of the top of the ball hole, the top of the limiting rod 13 cannot be locked into the bottom of the hole of the limiting sleeve 34.

[0027] Furthermore, with one hand pressing down on the top of the mounting plate 31, the other hand inserts the bottom block of the handle 4 into the top insertion hole of the connecting rod 32, and rotates the handle 4 to control the rotation of the connecting rod 32. The drive gear 33, which is fixed to the surface of the connecting rod 32, rotates. Since the drive gear 33 meshes with the driven gear 36, the drive gear 33 drives all the driven gears 36 to rotate synchronously, thereby causing the mounting ring 37 at the bottom of the movable ring 35 to rotate, which in turn drives the trimming wheel 38 to rotate. The rotating trimming wheel 38 polishes the burrs and other rough edges on the inner side of the top of the ball hole until the limit insert 13 is completely inserted into the bottom insertion hole of the limit sleeve 34, thereby achieving effective polishing and ensuring the trimming effect.

[0028] It should be noted that the parts not covered in this utility model are the same as or can be implemented using existing technology; the various drives in this utility model can be implemented by corresponding power structures such as cylinders, oil cylinders, electric cylinders, and motors in conjunction with connecting rods, guide rods, etc., and are not limited to the structures described in the specification and the drawings.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
