Description

Technical Field

[0001] The utility model relates to the field of decoration processing, in particular to a decoration grinding machine. Background Art

[0002] The decorations currently on the market generally need to be ground and polished after the enamel (imitation enamel) is colored, so that the metal wires on the surface of the decorations are bright and neat and level with the enamel, so that they can be electroplated.

[0003] At present, the grinding process of ornaments includes water grinding - cleaning and drying - rough polishing - fine polishing. There are special water grinders, which are mainly used to remove burrs on the surface of ornaments after enamel (imitation enamel) coloring and to make the metal surface and enamel (imitation enamel) flat. The working steps are to put the ornaments into a special bakelite fixture, and grind the surface of the ornaments with a sanding belt by moving the ornaments left and right, front and back. While grinding, the product should be rinsed with water all the time. On the one hand, it can cool the product, and on the other hand, it can wash away the dust produced by grinding to prevent the ornaments from deepening scratches. For some ornaments with high requirements for surface wear marks, the water grinding process must go through three steps, that is, grinding the product with 600, 800, and 1000 sanding belts respectively.

[0004] Currently, water mills use special jigs, and because the processing standards are different, the thickness and parallelism of each jig are different. Every time the product is changed, the equipment needs to be adjusted.

[0005] Cleaning and drying:

[0006] After rinsing the water-polished decorations, dry the water and allow them to proceed to the next step of rough polishing:

[0007] Most of them are operated manually, using a hemp wheel to remove the metal sand marks exposed on the front of the decoration.

[0008] Fine polishing:

[0009] Most of the work is done manually, using a cloth wheel to further polish the metal on the front of the ornament and remove dirt from the surface of the enamel (imitation enamel), making it smooth and flat, so that the ornament can be electroplated.

[0010] In view of this, this processing method not only increases the processing cost and requires multiple fixtures to complete, but also increases the operation time, resulting in reduced processing efficiency. Utility Model Content

[0011] The existing decoration processing not only increases the processing cost and requires multiple jigs to complete, but also increases the operation time, resulting in reduced processing efficiency.

[0037] In addition, reference Figures 1 to 4 A walking support wheel is also installed at the bottom end of the support frame 1, and a support member is also installed to stabilize the use of the grinder.

[0038] Preferably, reference Figures 1 to 4 The grinding assembly 3 includes a motor 301, a fixed block 302 and a grinding head 303. The fixed block 302 is mounted on the side wall of the connecting plate 7 close to the support frame 1 by screws. The motor 301 is mounted on the top of the fixed block 302. The grinding head 303 is arranged at the bottom of the fixed block 302, and the top of the grinding head 303 is connected to the output shaft of the motor 301.

[0039] Furthermore, the grinding head 303 is circular, the size of the grinding head 303 is larger than the size of the fixed block 302 , and the grinding head 303 is rotatably connected to the fixed block 302 through the motor 301 .

[0040] It should be noted that the grinding head 303 is a fiber grinding wheel, that is, a dry grinding head. The center part of the grinding head 303 is fixedly connected to the output shaft of the motor 301, and then the grinding head 303 will rotate through the operation of the motor 301. In addition, the fixed block 302 and the connecting plate 7 are installed close to the side wall of the support frame 1, and when the hydraulic cylinder 8 is extended and retracted to drive the connecting plate 7 to move along the guide rail 6, the rotating grinding head 303 will be driven to descend.

[0041] Furthermore, refer to Figures 1 to 4The fixture assembly 4 includes a first fixture 401 and a second fixture 402 , and the first fixture 401 and the second fixture 402 are both located at the top of the fixing plate 5 .

This design is for the diamond baffle 9 on the retaining edge to synchronously trim the fiber wheel, that is, the above-mentioned grinding head 303 when grinding the product, so that the grinding head 303 can remain flat, and avoid irregular grooves on the grinding head 303 due to wear as the number of grinding increases, which affects the subsequent grinding. At the same time, the four sliding grooves 10 opened on the top of the fixed plate 5 are for the first fixture 401 and the second fixture 402 to slide close to the bottom of the grinding head 303 for grinding.

[0047] In summary, the grinding machine puts the ornaments on the first fixture 401, and the first fixture 401 automatically shifts to the grinding head 303, and then the grinding head 303 descends for grinding. While grinding, the ornaments to be ground can be placed on the second fixture 402. After the finished ground ornaments come out, the second fixture 402 moves to the grinding head 303 for grinding. At this time, the finished ornaments can be taken out of the first fixture 401, and the ornaments to be ground can be put in. This cycle continues. Compared with the prior art, the present application has the following beneficial effects: 1. Reduce the operation time: by replacing water grinding with dry grinding. In this way, the quality of dry grinding directly reaches the quality of rough polishing, that is, dry grinding is used to replace the original three steps of water grinding, cleaning and drying, and rough polishing. 2. Reduce processing costs: By changing the special jig into a universal jig and adjusting the retaining edge to ensure that each product is applicable, the relative relationship between the first jig 401 and the second jig 402 and the grinding head 303 can be ensured, and there is no need to make a special jig for each product.

[0048] It is necessary to add that: Figure 3 The fixture in the embodiment may be the first fixture 401 or the second fixture 402, so as to more advantageously observe the installation position of the diamond baffle 9, and then, by Figure 1 It can be seen that the diamond baffle plates 9 of the first fixture 401 and the second fixture 402 are corresponding.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
