[0001] The invention relates to the technical field of polishing equipment, and in particular to a device and method for making irregular patterns on the surface of a sculpture. Background Art

[0002] Silver jewelry is a kind of jewelry made of metal silver, with smooth texture and rich luster. Sculpture is a kind of plastic art, also known as carving, which is the general term for the three creation methods of carving, engraving and shaping. In order to reflect the beauty of silver jewelry, silver jewelry is usually polished by sculpture technology. The purpose of polishing is to reduce the surface roughness of the workpiece to obtain a bright and flat surface. Polishing is to modify the surface of the workpiece by mechanical, chemical or electrochemical action to make the surface smooth and glossy.

[0003] There are many types of silver jewelry. When polishing the irregular patterns on the surface of rectangular silver jewelry, it is necessary to spray the polishing liquid inside the irregular pattern, and then use the polishing equipment to polish the irregular pattern inside to make the surface of the silver jewelry smoother.

[0004] However, the existing polishing liquid is directly sprayed on the surface pattern of the silver jewelry, and the polishing liquid cannot be sprayed at the designated position, resulting in waste of polishing liquid. It is also troublesome to clean up the excess polishing liquid, which reduces the efficiency of making irregular patterns on the surface of silver jewelry. Summary of the invention

[0005] The purpose of the present invention is to propose a device and method for making irregular patterns on the surface of a sculpture in order to solve the problem that the existing polishing liquid is directly sprayed on the pattern on the surface of the silver jewelry, and the polishing liquid cannot be sprayed according to the specified position, resulting in waste of polishing liquid and it is also troublesome to clean up the excess polishing liquid.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technology: a device for making irregular patterns on the surface of a sculpture, comprising a shell, a grinding mechanism is installed inside the shell, the grinding mechanism includes a driving member installed in the shell, a rotating shaft is installed at the output end of the driving member, a sleeve is fixed on the shell outside the rotating shaft, a polishing liquid supply assembly that rotates synchronously with the rotating shaft is installed in the sleeve, a grinding component is inserted at the bottom end of the rotating shaft, and the upper end of the grinding component is rotatably connected to the sleeve through a bearing; the grinding component includes a first grinding head for grinding a pattern of a horizontally placed sculpture perpendicularly and a second grinding head for grinding parallel to the horizontal plane, and the first grinding head is fixedly connected to the second grinding head, an S-shaped liquid outlet groove matched with the polishing liquid supply assembly is opened on the outside of the second grinding head to provide polishing liquid for the grinding component; it also includes a guide assembly installed on the outside of the second grinding head, the guide assembly includes a guide rod matched with the liquid outlet groove, and a bellows matched with the guide rod is fixedly installed on the sleeve.

[0008] The driving member includes a base and a motor fixedly mounted inside the housing, the rotating shaft is fixedly connected to the power output shaft of the motor, the rotating shaft passes through the sleeve and the second grinding head in sequence and is plugged into the upper end surface of the first grinding head. A limit plate is fixedly mounted on the bottom of the rotating shaft, and a slot matching the limit plate is provided on the upper end surface of the first grinding head.

[0009] As a further description of the above-mentioned technique, a device for making irregular patterns on the surface of a sculpture:

[0010] The polishing liquid supply assembly includes a storage plate fixedly mounted on the inner wall of the sleeve, a transmission plate fixedly mounted on the outer wall of the rotating shaft, extrusion cylinders symmetrically mounted on both ends of the transmission plate, and a conduit placed between the extrusion cylinder and the storage plate. A liquid storage bag for storing polishing liquid is fixedly mounted on the inner wall of the sleeve above the storage plate, the liquid inlet end of the conduit is connected to the liquid storage bag, and the liquid outlet end of the conduit extends to the inside of the second polishing head. The upper end of the extrusion cylinder has a curved portion, which conflicts with the liquid storage bag.

[0011] As a further description of the above-mentioned technique, a device for making irregular patterns on the surface of a sculpture:

[0012] The guide assembly also includes a limit ring fixedly mounted on the bellows, an arc-shaped slider is slidably mounted on the inner wall of the limit ring, the arc-shaped slider is fixedly connected to the guide rod, and a scraper ring matching the second grinding head is fixedly mounted on the guide rod.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the device and method for making irregular patterns on the surface of a sculpture in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1-Figure 7 As shown, the present invention provides: a device for making irregular patterns on the surface of a sculpture, comprising a housing 10, a grinding mechanism 20 is installed inside the housing 10, the grinding mechanism 20 comprises a driving member installed in the housing 10, a rotating shaft 22 is installed at the output end of the driving member, the driving member comprises a base and a motor 21 fixedly installed inside the housing 10, the rotating shaft 22 is fixedly connected to the power output shaft of the motor 21, and the motor 21 can drive the rotating shaft 22 to rotate;

[0031] Among them, a sleeve 11 is fixed on the outer shell 10 of the rotating shaft 22, and a polishing liquid supply component 25 that rotates synchronously with the rotating shaft 22 is installed in the sleeve 11, that is, the rotating shaft 22 can only transfer the polishing liquid when it rotates. When the rotating shaft 22 does not rotate, the polishing liquid will not flow out by itself, avoiding waste of polishing liquid.

[0032] In further detail, a grinding component 26 is inserted at the bottom end of the rotating shaft 22, and the upper end of the grinding component 26 is rotatably connected to the sleeve 11 through a bearing; the grinding component 26 includes a first grinding head 262 for grinding the sculpture pattern perpendicular to the horizontal surface and a second grinding head 261 for grinding parallel to the horizontal surface, and the first grinding head 262 is fixedly connected to the second grinding head 261; wherein, the outer wall of the second grinding head 261 is fixedly connected to the inner ring wall of the bearing, and the outer ring wall of the bearing is threadedly connected to the sleeve 11, so that when the bearing is rotated, the second grinding head 261 can drive the first grinding head 262 to disengage from the sleeve 11, which is convenient for replacing the grinding head of the grinding equipment. In addition, the rotating shaft 22 passes through the sleeve 11 and the second grinding head 261 in sequence and is plugged into the upper end surface of the first grinding head 262. A limit plate 28 is fixedly installed at the bottom of the rotating shaft 22, and a slot matching the limit plate 28 is provided on the upper end surface of the first grinding head 262; when the limit plate 28 is inserted into the slot, the rotating shaft 22 can drive the first grinding head 262 to rotate; when the rotating shaft 22 rotates, the rotating shaft 22 can drive the first grinding head 262 and the second grinding head 261 to rotate synchronously, thereby achieving the grinding processing of irregular patterns on the surface of the sculpture.

[0033] like Figure 1-Figure 4 and Figure 6-Figure 7 As shown, the second grinding head 261 is provided with an S-shaped liquid outlet groove 27 adapted to the polishing liquid supply assembly 25, and the S-shaped liquid outlet groove 27 provides polishing liquid for the grinding component 26; at the same time, the S-shaped liquid outlet groove 27 surrounds the outer wall of the second grinding head 261; the design of the S-shaped liquid outlet groove 27 enables the grinding head to remove harder protruding impurities during the rotation process, thereby improving the grinding quality. A truncated cone-shaped liquid guide column 35 is fixedly installed on the upper end surface of the first grinding head 262 inside the second grinding head 261. The liquid guiding column 35 has the effect of guiding flow. When the second polishing head 261 is polishing parallel to the silver jewelry, the contact between the rotating S-shaped liquid outlet 27 and the silver jewelry is always a single point of the liquid outlet 27, and the polishing liquid entering the second polishing head 261 will always accumulate at the position in contact with the silver product due to the effect of gravity, so that the polishing liquid can reach the position of the sculpture pattern from the liquid outlet 27, avoiding the waste of polishing liquid; in addition, the liquid guiding column 35 with a truncated cone structure can make the polishing liquid reaching the end position of the second polishing head 261 flow back to the liquid outlet 27 in time, and flow through the liquid outlet 27 to the designated position.

[0034] like Figure 2-Figure 4As shown, the polishing liquid supply assembly 25 includes a storage plate 252 fixedly mounted on the inner wall of the sleeve 11, a transmission plate 253 fixedly mounted on the outer wall of the rotating shaft 22, and extrusion cylinders 254 are symmetrically rotatably mounted on both ends of the transmission plate 253. A catheter 251 is placed between the extrusion cylinder 254 and the storage plate 252, wherein the extrusion cylinder 254 is rotatably connected to the transmission plate 253 through a bearing, which can prevent the extrusion cylinder 254 from causing damage to the catheter 251; when the polishing equipment is working, the rotation of the rotating shaft 22 can drive the rotation of the transmission plate 253, and when the transmission plate 253 rotates, the transmission plate 253 can drive the extrusion cylinder 254 to squeeze the tube body of the catheter 251, and the squeezed part generates negative pressure, and the liquid is driven along with the rotation of the extrusion cylinder 254, and finally discharged from the other end. The above working principle is the same as the working principle of the peristaltic pump in the prior art.

[0035] In further detail, a liquid storage bag 24 for storing polishing liquid is fixedly installed on the inner wall of the sleeve 11 above the storage plate 252. The liquid storage bag 24 is a rubber material with an elastic bag structure in the prior art, which can gradually shrink as the liquid is lost, thereby ensuring that the liquid inlet of the catheter 251 can always be in contact with the liquid; in addition, the liquid filling end of the liquid storage bag 24 passes through the sleeve 11 to prevent the liquid filling end from hindering the deformation of the liquid storage bag 24.

[0036] In further detail, the liquid inlet end of the conduit 251 is connected to the liquid storage bag 24, and the liquid outlet end of the conduit 251 extends to the inside of the second polishing head 261. The upper end of the extrusion cylinder 254 has a curved portion, and it contacts the liquid storage bag 24. When the extrusion cylinder 254 rotates, it can squeeze the liquid storage bag 24, so that the polishing liquid inside the liquid storage bag 24 is stirred from the outside, thereby preventing the polishing liquid from condensing inside the liquid storage bag 24, and at the same time ensuring that the conduit 251 can absorb uniform liquid, thereby achieving uniform spraying of the polishing liquid.

[0037] As Figure 5-Figure 7 As shown, it also includes a guide assembly 30 mounted on the outside of the second grinding head 261, and the guide assembly 30 includes a guide rod 33 adapted to the liquid outlet trough 27, and a bellows 34 adapted to the guide rod 33 is fixedly installed on the sleeve 11. The bellows 34 is a foldable plastic material with the same principle as the retractable straw in the prior art. The bellows 34 is stretched to the bottom to block the polishing liquid sprayed from the liquid outlet trough 27, so that the blocking liquid can slide along the bellows 34 to achieve spraying at the grinding position. In addition, the bellows 34 can protect the grinding head under normal conditions to prevent the grinding head from being bumped and damaged.

[0038] In further detail, the guide assembly 30 also includes a limit ring 31 fixedly mounted on the bellows 34 to match, an arc-shaped slider 36 is slidably mounted on the inner wall of the limit ring 31, the arc-shaped slider 36 is fixedly connected to the guide rod 33, and a scraper ring 32 adapted to the second grinding head 261 is fixedly mounted on the guide rod 33. The arc-shaped slider 36 is used to support the guide rod 33, so that the bellows 34 can drive the guide rod 33 and the scraper ring 32 to clean the surface of the liquid outlet trough 27 and the second grinding head 261 during the lifting process, thereby extending the service life of the second grinding head 261, and at the same time, it can prevent the accumulation of impurities on the surface of the second grinding head 261 when it is used for a long time, thereby ensuring the grinding quality of the grinding equipment.

[0039] A method for making an irregular pattern on a sculpture surface comprises the following steps:

[0040] S1. The motor 21 is used to drive the rotating shaft 22 to rotate. The rotating shaft 22 drives the first grinding head 262 to grind the sculpture pattern vertically and drives the second grinding head 261 to grind parallel to the horizontal plane. When the rotating shaft 22 rotates, it drives the extrusion cylinder 254 in the polishing liquid supply assembly 25 to squeeze the liquid storage bag 24, so that the polishing liquid in the liquid storage bag 24 is discharged from the liquid outlet tank 27, providing basic conditions for grinding.

[0041] S2. When the bellows 34 is pulled down to the bottom, the polishing liquid thrown out of the liquid outlet groove 27 can be limited, so that the polishing liquid falls along the inner wall of the bellows 34 to the polishing part of the sculpture surface. When the bellows 34 is pulled back, the bellows 34 will drive the guide rod 33 and the scraper ring 32 to slide along the liquid outlet groove 27 to clean the surface of the second polishing head 261 and the inside of the liquid outlet groove 27.

[0042] Working principle: When polishing the irregular pattern on the surface of the sculpture, first start the motor 21 to make the motor 21 rotate slowly and at a uniform speed. The rotation of the rotating shaft 22 can drive the rotation of the transmission plate 253. When the transmission plate 253 rotates, the transmission plate 253 can drive the extrusion cylinder 254 to squeeze the tube body of the catheter 251. The squeezed part generates negative pressure, and the liquid is driven along with the rotation of the extrusion cylinder 254, and finally discharged from the other end, so that the liquid inside the liquid storage bag 24 can be transferred to the inside of the second polishing head 261; the S-shaped liquid outlet trough 27 provides polishing liquid for the polishing component 26; at the same time, the S-shaped liquid outlet trough 27 surrounds the outer wall of the second polishing head 261; the design of the S-shaped liquid outlet trough 27 enables the polishing head to cut off harder protruding impurities during the rotation process, thereby improving the polishing quality;

[0043] Among them, since the upper end of the extrusion cylinder 254 has a curved portion and contacts the liquid storage bag 24, the extrusion cylinder 254 can squeeze the liquid storage bag 24 when rotating, so that the polishing liquid inside the liquid storage bag 24 is stirred from the outside, thereby preventing the polishing liquid from condensing inside the liquid storage bag 24, and at the same time ensuring that the catheter 251 can absorb uniform liquid, thereby achieving uniform spraying of the polishing liquid.

[0044] Finally, stretching the bellows 34 to the bottom can shield the polishing liquid sprayed from the liquid outlet trough 27, so that the shielding liquid can slide down the bellows 34 to achieve spraying on the grinding position; during the lifting process of the bellows 34, the guide rod 33 and the scraper ring 32 can be driven to clean the surface of the liquid outlet trough 27 and the second grinding head 261, thereby extending the service life of the second grinding head 261 and avoiding the accumulation of impurities on the surface of the second grinding head 261 when used for a long time, thereby ensuring the grinding quality of the grinding equipment.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes to the device and method for making irregular patterns on the surface of a sculpture and the inventive concept according to the technology of the present invention, which should be covered by the protection scope of the present invention.
