Description

Technical Field

[0001] The utility model relates to a polishing device, in particular to a polishing device for processing gypsum sculptures. Background Art

[0002] Gypsum sculptures are sculptures made of gypsum as the main material. Its color level and feel are particularly suitable for sketching objects, and because of its low price, easy reproduction and long-term preservation, it has become a popular indoor sculpture variety.

[0003] The process of making plaster sculptures includes designing, preparing materials and tools, making models, applying mold release agents, making molds, casting plaster, and subsequent grinding and polishing. First, the original concept drawing is designed based on factors such as the size, shape, posture and details of the sculpture, and the required plaster, molds, chisels, files, sandpaper and other tools are prepared. Next, a model of the plaster sculpture is made according to the design drawing, and a release agent is applied to facilitate removal from the mold. After that, a mold is made and the plaster is cast, and it is removed after solidification. Finally, grinding and polishing are performed to make the sculpture smooth and delicate.

[0004] During the grinding and polishing process, you can use hand tools or power tools to gradually use sandpaper of different coarseness and fineness to grind until the surface reaches the desired smoothness. Polishing agents can be used during polishing to make the sculpture surface more beautiful. However, at present, when polishing plaster sculptures, it is generally done by holding the plaster sculptures manually, and then the plaster sculptures are brought close to the polishing machine to perform the polishing operation. However, during the polishing process, the plaster sculptures are prone to heat up, resulting in the inability to perform the polishing operation for a long time, and if you are not careful, it is easy to cause damage to your hands.

It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0020] Embodiment: A polishing device for processing plaster sculptures, such as Figure 1-3 As shown, it includes a polishing machine 1, a base 101, a mounting plate 2, a limiting rod 3, a movable plate 4, a placement frame 5, a rotating shaft 51, a knob 52, a fixing plate 6, a clamping plate 7 and a first fixing screw 8. The polishing machine 1 is fixedly installed on the top right side of the base 101 by bolts, and the mounting plate 2 is fixedly connected to the top left side of the base 101 by bolts. The limiting rods 3 are connected to the front and rear sides of the mounting plate 2. The movable plate 4 is slidably connected between the two limiting rods 3. The upper part of the movable plate 4 is rotatably connected to the rotating shaft 51. The left end of 51 is connected with a knob 52, and the rotating shaft 51 is rotated by the knob 52 to facilitate the adjustment of the polishing position of the gypsum sculpture. The right end of the rotating shaft 51 is connected with a placing rack 5, and the placing rack 5 is arranged in an L shape. A fixing mechanism is arranged on the placing rack 5, and the fixing mechanism is used to fix the gypsum sculpture. A fixing plate 6 is connected to the upper right part of the placing rack 5, and a clamping plate 7 is slidably connected to the right side of the placing rack 5. A first fixing screw 8 is threadedly connected to the middle part of the fixing plate 6, and the bottom end of the first fixing screw 8 is rotatably connected to the fixing plate 6.

[0021] like Figure 1-3 As shown, a handle 9 is also included. The left side of the movable plate 4 is symmetrically connected to the handle 9 front and back, and the handle 9 is used to facilitate the movement of the movable plate 4.

[0022] like Figure 1 and Figure 4As shown, it also includes an extrusion plate 10, a rubber pad 11 and a second fixed screw 12. The extrusion plate 10 is slidably connected to the upper part of the movable plate 4, the extrusion plate 10 is located above the rotating shaft 51, the bottom of the extrusion plate 10 is connected to the rubber pad 11, the top of the movable plate 4 is threadedly connected to the second fixed screw 12, the bottom end of the second fixed screw 12 is rotatably connected to the extrusion plate 10, and the extrusion plate 10 drives the rubber pad 11 to contact the rotating shaft 51 by rotating the second fixed screw 12, thereby fixing the position of the rotating shaft 51.

[0023] like Figure 1 As shown, an anti-skid pad 13 is also included. The top ends of the first fixing screw 8 and the second fixing screw 12 are both connected with the anti-skid pad 13. The anti-skid pad 13 can facilitate the rotation of the first fixing screw 8 and the second fixing screw 12.

Then the polishing machine 1 is started to run, and the movable plate 4 is pushed to move right through the handle 9, so that the gypsum sculpture piece is driven to move right through the placement rack 5 to contact the polishing machine 1, and the gypsum sculpture piece is polished by the polishing machine 1. During the polishing process, polishing agent can be added to the surface of the gypsum sculpture piece. When the polishing position of the gypsum sculpture piece needs to be changed, the movable plate 4 is moved to the left, and then The second fixing screw 12 is rotated so that the extrusion plate 10 drives the rubber pad 11 to move upward and separate from the rotating shaft 51. At this time, the rotating shaft 51 is rotated by the knob 52, thereby driving the gypsum sculpture to rotate through the placement frame 5. When the gypsum sculpture is rotated to the position requiring polishing, the second fixing screw 12 is reversed so that the extrusion plate 10 drives the rubber pad 11 to move downward and contact with the rotating shaft 51 and fix its position, and the gypsum sculpture can be repeatedly polished; after polishing is completed, the polishing machine 1 is turned off, and the first fixing screw 8 is reversed so that the clamping plate 7 moves upward to loosen the gypsum sculpture, and the polished gypsum sculpture can be removed.
