Detailed implementation manners
[0021] The following will describe in detail the implementation manners of the present application in conjunction with the drawings and embodiments, so as to fully understand how the present application uses technical means to solve technical problems and achieve the implementation process of technical effects and implement accordingly.
[0022] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0023] Figures 1 - 3 As an embodiment of the present utility model, the specific problem addressed by this specific embodiment is as follows: When processing beads, in order to make the surface of the beads smoother, it is necessary to polish the surface of the beads. Currently, the bead surface polishing tools are not convenient for fixing beads with different apertures, making polishing inconvenient. Moreover, for existing polishing tools, most polish the beads by holding a polishing sandpaper by hand. The speed of rotation and even the number of times the sandpaper rubs against the surface are actively controlled, which easily results in uneven polishing due to uneven polishing times or uneven rotation speeds. The beads are not round after polishing, affecting the value of the beads. A bead jewelry surface polishing device described in this solution utilizes the relative movement between the polishing chamber 2 and the top plate 32 to cause the beads to be polished to be subjected to the frictional force of the sandpaper during rotation to achieve a smooth surface. On this basis, in order to enable the beads to rotate synchronously with the polishing chamber 2 and at the same time be able to rotate self, thereby enhancing the circumferential frictional force so that the beads can be evenly polished. When the rubber ring group 37 provided on the top plate 32 is stationary, it generates a frictional force on the rotating beads to cause them to rotate self. Thus, the beads can be evenly polished in the polishing chamber 2, improving the polishing effect.
[0024] A surface polishing device for beaded ornaments is specifically provided with a base 1, on which a polishing chamber 2 for accommodating polished beads is installed, in which a polishing piece 3 for acting on the beads to be polished is arranged, and in which a central axis 31 penetrating the polishing chamber 2 is arranged, and a top plate 32 for controlling the movement height of the beads to be polished in the polishing chamber 2 is installed at the upper end of the polishing chamber 2, and the central axis 31 penetrating the top plate 32 and being rotatably connected with the top plate 32 is arranged. The height of the top plate 32 is adapted to the diameter of the beads to be polished, so as to avoid the beads from jumping due to sufficient space during polishing and causing scratches on the beads themselves, and cracks on the surface of the beads, and a driving motor for driving the central axis 31 to rotate and a controller for controlling the opening and closing of the driving motor are arranged in the base 1. The bottom surface of the grinding chamber 2 is provided with a grinding groove 38 that matches the diameter of the inner groove 36. A pad 39 is provided inside the grinding groove 38 and sleeved on the central axis 31. A rubber strip 372 is provided on the edge of the grinding groove 38 to prevent the beads from shifting during the rotation process and causing damage to the beads by the edge of the grinding groove 38. When in use, the grinding sandpaper is sleeved on the pad 39, so that the sandpaper can rotate synchronously with the grinding chamber 2 to grind the surface of the beads.
[0025] The diameter of the top plate 32 is smaller than the inner diameter of the grinding chamber 2. Support members 33 for controlling the distance between the top plate 32 and the grinding chamber 2 are symmetrically arranged on the top plate 32. The support members 33 are arranged on the base 1. The support members 33 can drive the top plate 32 to move in the inner cavity, thereby raising or lowering the distance between the top plate 32 and the grinding groove 38, thereby enhancing the grinding adaptability to beads of different sizes.
[0026] The center of the top plate 32 is provided with a sleeve 34 which is sleeved on the central axis 31 and is interference connected with the top plate 32. Extension plates 35 are installed at both ends of the sleeve 34. The support member 33 includes a bent connecting rod 331 installed on both sides of the base 1. A connecting sleeve 332 is sleeved on the bent connecting rod 331. The connecting sleeve 332 is connected to a support rod 333 extending toward the extension plate 35. The support rod 333 and the extension plate 35 are fixed by bolts. The support rod 333 is bent at the junction with the wall of the grinding chamber 2. Therefore, the support rod 333 is used to drive the top plate 32 to move up and down, and the support rod 333 will not be limited by the structure of the support rod 333 itself, causing the top plate 32 to be unable to move up and down. After sinking into the grinding chamber 2, the upper and lower ends of the connecting sleeve 332 are provided with limit plates 334 threadedly connected to the bent connecting rod 331. First, the position of the limit plate 334 at the lower end of the sleeve 34 is determined. After it is determined, the connecting sleeve 332 is sleeved on the bent connecting rod 331, and is supported by the limit plate 334 so that it cannot slide downward. Then, the limit plate 334 at the upper end of the connecting sleeve 332 is also screwed in, thereby limiting the position of the connecting sleeve 332 and the support rod 333. After the beads are placed, the extension plate 35 is connected to the support rod 333, and the distance between the top plate 32 and the grinding groove 38 can reach the expected distance.
[0027] The sleeve 34 penetrates through the top plate 32. The diameter of the sleeve 34 is adapted to the diameter of the cushion plate 39. An inner groove 36 is formed on the bottom surface of the top plate 32. During specific use, a polishing sandpaper is sleeved on the sleeve 34, and then the rubber ring group 37 is placed at the lower end of the polishing sandpaper, directly contacting the beads. A rubber ring group 37 sleeved on the sleeve 34 is arranged in the inner groove 36. The rubber ring group 37 includes a central ring 371 sleeved on the sleeve 34 and rubber strips 372 connected to the central ring 371 and extending circumferentially. The cut-off ends of the rubber strips 372 are located on the groove wall of the inner groove 36. The rubber strips 372 can generate frictional force on the rotating beads each time they meet the beads, thereby prompting the beads to rotate. Furthermore, when the beads rotate with the polishing bin 2, they can also rotate by themselves. Thus, it is avoided that only the upper and lower two surfaces are polished, resulting in uneven polishing and defective products.
[0028] The control mode of the present utility model is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming of those skilled in the art. The provision of power also belongs to the common knowledge in this field. And the present utility model is mainly used to protect mechanical devices, so the control mode and circuit connection of the present utility model will not be explained in detail.
[0029] It should be noted that in this article, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements but also includes other elements not explicitly listed, or further includes elements inherent to such process, method, article or device.
[0030] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
