[0002] There are some common techniques and skills in porcelain carving, such as engraving, relief, hollowing, decals, painting, and stacking. For porcelain carving, the pattern needs to be drawn on the surface of the porcelain. After the outline is polished, a handheld polisher can be used to polish the surface from coarse to fine until the surface is as smooth as a mirror. Especially for porcelain with curvature, the polisher is more flexible to use. The handheld polisher is in the shape of a pen holder, which is slender and light. A drive motor is set inside the pen holder shell. After pressing the start switch, the drive motor drives the grinding head to rotate, and the engraving area of ​​the porcelain can be polished.

[0003] The polishing machine disclosed in the document with Chinese patent number 202122234284.9 and name "A polishing machine for ceramic processing" includes a base, a support rod is slidably engaged on the upper side of the base, a tooth groove is opened on one side of the support rod, and a mouth-shaped plate is slidably sleeved on the circumference of the support rod, and two gears are rotatably engaged between the inner walls on opposite sides of the mouth-shaped plate, and the gear teeth between the two gears are meshed, and one of the gears on the inner walls on opposite sides of the tooth groove is meshed respectively, and a positioning plate is installed on the upper side of the mouth-shaped plate, and the adjusted mouth-shaped plate and the cylinder are conveniently fixed by the first bolt and the second bolt, thereby reducing the probability of the grinding wheel damaging the porcelain due to the sliding of the polishing machine, and the polishing machine can adjust the grinding position in multiple directions and angles through the cooperation between the support rod, the mouth-shaped plate, the sliding rod, and the cylinder, thereby increasing the working range, improving flexibility, and reducing the probability of reduced polishing efficiency and low production efficiency due to the need to frequently move the porcelain material.

[0004] However, when polishing porcelain with an existing polishing machine, in order to prevent sweating and slipping, the user holds the handle of the pen body shell with two fingers inserted into the anti-slip gripper, and the polished waste often falls to the lower wall of the carving area, blocking the line of sight. The polishing needs to be stopped and the waste needs to be cleaned manually, which is inconvenient to blow and clean the waste in the carving area while polishing. Therefore, these problems need to be solved urgently. Summary of the invention

[0005] The utility model aims to provide a hand-held polishing machine for carving in porcelain production, which uses compressed air to blow away waste materials during polishing without secondary cleaning, thereby preventing waste materials from gathering in the carving area to cause obstruction.

[0006] The technical solution adopted by the utility model is as follows:

[0007] A hand-held polishing machine for engraving in porcelain production comprises a pen-shaped shell and a polishing head rotatably connected to the pen-shaped shell, a handle is fixedly installed on one side of the pen-shaped shell, an air pump is fixedly installed inside the handle, a hard tube is fixed on the air outlet end of the air pump, one end of the hard tube extends out of the handle and is annularly bent, the annularly bent part of the hard tube is wrapped around the outside of the pen-shaped shell, a plurality of air blowing pipes are connected and fixed to the annularly bent part of the hard tube, and the air outlets of the air blowing pipes are all directed toward the polishing head away from the pen-shaped shell. At one end, when processing porcelain, the start switch can be pressed, and the all-copper motor will rotate the grinding head. The pen-shaped shell and the handle can be held to move the grinding head, contact the porcelain carving area for grinding, and the air pump is powered on to continuously draw air, compress the air along the hard tube and pump it to each air blow pipe, so that the air blow pipe will spray the compressed air flow to the grinding position of the grinding head, and use compressed air to blow away the waste while grinding, without the need for secondary cleaning, to prevent waste from accumulating in the carving area and causing obstruction, so that the entire porcelain carving area is exposed to the line of sight to improve the polishing accuracy.

[0008] The air outlets of the air blowing pipes are all connected and fixed with metal nozzles, which are all trumpet-shaped. The narrow air outlets of the metal nozzles can limit the flow direction of compressed air and align them with the grinding position of the grinding head so as to align them with the waste materials that are ground off.
