Description

Technical Field

[0001] The utility model relates to the technical field of gold ornament processing, in particular to a surface polishing mechanism for gold ornaments. Background Art

[0002] Polishing the surface of gold jewellery is a fine metal processing technique that aims to enhance the appearance, texture and gloss of gold jewellery. This process usually includes several key steps: First, the surface of the gold jewellery is initially polished using sandpaper or a grinding wheel to remove surface irregularities and scratches. Next, the gold jewellery is carefully polished using polishing pastes and polishing cloths of varying coarseness and fineness, a step that can gradually enhance the gloss of the gold jewellery. During the polishing process, the operator needs to carefully control the force and direction to avoid excessive wear or the creation of new scratches.

[0003] Existing polishing methods often need to be combined with manual methods. If polishing is done purely mechanically, the surface of the gold jewelry needs to be polished with polishing abrasives. However, due to the relatively high price of gold jewelry, even if the weight is lost on a gram basis, it is a huge loss for the gold jewelry. Therefore, there is a need to be able to polish the surface of gold jewelry without using solid particle abrasives.

[0004] Therefore, a surface polishing mechanism for gold ornaments is proposed to solve or alleviate the above problems. Utility Model Content

[0027] A surface polishing mechanism for gold jewelry, such as Figure 1 As shown, it includes a circular sleeve 13 with an opening and a driving component arranged in the circular sleeve 13, and the opening can be opened and closed. Specifically, the circular sleeve 13 located at the opening is hinged with a cover 14, and the cover 14 is detachably connected to the circular sleeve 13 at one end away from its rotating connection. The circular sleeve 13 realizes the openable and closable setting of the opening through the cover 14, and a polishing cloth layer is fixedly connected to the inner wall of the circular sleeve 13.

[0028] like Figure 2 As shown, the driving assembly includes an inner transmission belt 19 rotatably arranged in the circular sleeve 13, an inner driving wheel 15 rotatably connected to the inner wall of the circular sleeve 13, an outer driving wheel 7, and a gathering shaft 16 and a clamping shaft 17 fixedly connected to the inner wall of the circular sleeve 13. The width of the inner transmission belt 19 is equal to the inner width of the circular sleeve 13. A polishing cloth layer is also fixedly connected to the surface of the inner transmission belt 19. The inner transmission belt 19 is sleeved on the outer sides of the inner driving wheel 15 and the inner driven wheel 18, and the inner transmission belt 19 passes between the gathering shaft 16 and the clamping shaft 17.

[0029] In addition, if Figure 1 As shown, the circular sleeve 13 can be rotatably arranged, and also includes a base 1, a plurality of legs 2 fixedly connected to the bottom surface of the base 1, a driving assembly, two sets of rotating seats 5, and a rotating shaft 6 rotatably connected in the rotating seat 5. The rotating seat 5 and the mounting seat 3 are all fixedly connected to the base 1. The rotating shaft 6 located in the two sets of rotating seats 5 are coaxially arranged with the circular sleeve 13, and the rotating shafts 6 on both sides are fixedly connected to the two side walls of the circular sleeve 13. The driving assembly is transmission-connected to one side of the rotating shaft 6 to drive the rotating shaft 6 and the circular sleeve 13 to rotate.

[0030] The driving assembly includes a mounting base 3, a driving motor 4 fixedly connected to the mounting base 3, an outer driving wheel 7 fixedly connected to the output shaft of the driving motor 4, an outer driven wheel 9 fixedly connected to a side rotating shaft 6, a main transmission belt 8 connecting the outer driving wheel 7 and the outer driven wheel 9, a secondary driving wheel 10 fixedly connected to the rotating shaft 6, a secondary driven wheel 11, a secondary transmission belt 12 connecting the secondary driving wheel 10 and the secondary driven wheel 11, and a connecting shaft. The connecting shaft passes through a circular sleeve 13 and is rotatably arranged. The inner driving wheel 15 and the secondary driven wheel 11 are both fixedly connected to the connecting shaft. The outer diameter of the secondary driving wheel 10 is larger than the outer diameter of the secondary driven wheel 11.

[0031] When the utility model is actually applied, it is only necessary to open the opening, and then put the gold ornaments into the circular sleeve 13, so that the gold ornaments are placed on the driving component or the inner circumferential wall of the circular sleeve 13, and then the opening of the circular sleeve 13 is reclosed by the cover 14, and then the driving motor 4 is started, so that the driving motor 4 drives the outer driving wheel 7 to rotate, and the outer driving wheel 7 drives the outer driven wheel 9 to rotate through the main transmission belt 8. Since the outer driven wheel 9 is coaxially fixedly connected to the rotating shaft 6, the rotating shaft 6 will also rotate in the rotating seat 5, and then drive the circular sleeve 13 to rotate together. The rotation of the rotating shaft 6 causes the secondary driving wheel 10 to rotate coaxially, and it drives the secondary driven wheel 11 to rotate through the secondary transmission belt 12. , and there is a difference in outer diameter between the two, which means that when the secondary driving wheel 10 rotates one circle, the secondary driven wheel 11 and the connecting shaft can rotate more than one circle, and the inner driving wheel 15 follows the connecting shaft to rotate in the circular sleeve 13, and the inner driving wheel 15 will also drive the inner driven wheel 18 to rotate, and then drive the inner transmission belt 19 to rotate in the circular sleeve 13. In this way, the driving component not only rotates with the circular sleeve 13, but also can rotate by itself, so that the gold ornaments can roll and rub multiple times in the circular sleeve 13, so that its surface can contact the polishing cloth layer, and then complete the polishing and grinding action, and no granular abrasives are needed in this process, and no excessive damage will be caused to the surface of the gold ornaments.

[0032] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
