Description

[0002] Color dot spraying is to spray colored paint in the form of dots onto the surface of soft porcelain plate through special equipment to form a unique decorative effect. The color dot patterns are rich and varied to meet personalized design needs. For example, a soft porcelain forming spraying device with patent number CN113681694A is to place the soft porcelain to be sprayed on a carrier plate, and then drive the sliding seat to translate on the cantilever through the connecting block, so that the sprayer sprays vertically along the first direction and the second direction, and sprays the soft porcelain in the carrier plate more quickly and evenly;

[0003] However, the above patent content only has the function of spraying soft ceramic panels, but there are certain limitations during operation:

[0004] First, in the actual operation process, the soft ceramic plate is only supported by the carrier plate, and the conventional placement of the soft ceramic plate is very likely to cause the plate body and the nozzle to be misaligned, resulting in the disorder of the spray pattern position, which greatly affects the color point spraying effect of the soft ceramic plate;

[0005] Secondly, the surface of soft porcelain products is uneven after color spraying, and the surface of the soft porcelain plate needs to be slightly polished to achieve a smooth and uniform coating surface. The above patent content only provides a single component with spraying, and no further polishing and finishing operations are performed after spraying. In view of the technical defects in this regard, a solution is now proposed. Summary of the invention

DETAILED DESCRIPTION

[0033] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than 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.

[0034] Example 1: Please refer to Figure 2 - Figure 4As shown, a multi-axis positioning color dot spraying device for the texture of soft porcelain products includes a base support mechanism 1 and a color spraying mechanism 2, the color spraying mechanism 2 is arranged at the upper end of the base support mechanism 1, wherein the base support mechanism 1 includes an L-shaped base 101, a support plate 102 and a limit plate 103 are arranged on the top surface of the L-shaped base 101, the limit plate 103 is arranged at the bottom of the support plate 102, a vertical rod 104 is fixedly installed at the center of the inner wall of the bottom of the L-shaped base 101, and the vertical rod 104 runs through the center of the limit plate 103;

[0035] Two vertical poles 105 are fixedly installed at both ends of the inner wall at the bottom of the L-shaped base 101, and the length of the second vertical pole 105 is twice that of the first vertical pole 104. Two sets of clamping rings 106 are fixedly installed on the top of the first vertical pole 104 and the second vertical pole 105. The outside of the first vertical pole 104 is located between the limit plate 103 and the clamping ring 106 at the bottom thereof, and a spring coil 107 is wound together. The outside of the second vertical pole 105 is located between the top surface of the supporting plate 102 and the clamping ring 106 at the top thereof, and a spring coil 2 108 is wound together.

[0036] The top surface of the limiting plate 103 is fixedly installed with a wedge-shaped abutment frame 109 at the front and rear ends and both sides, and the top of the wedge-shaped abutment frame 109 penetrates and extends to the upper end of the supporting plate 102. The L-shaped base 101 is internally provided with a transposition cylinder 110 at both ends, and the center of the bottom of the transposition cylinder 110 is rotatably connected to the surface of the L-shaped base 101 through a fixed rotating rod. A transmission wheel 111 is fixedly installed outside the two sets of rotating rods and located at the bottom of the transposition cylinder 110. The two sets of transmission wheels 111 are externally sleeved with a transmission belt, and a motor 112 is provided at the bottom of one set of transmission wheels 111.

[0037] The two groups of transposition cylinders 110 are mirror-symmetrical with respect to the central axis of the L-shaped base 101, and the upper and lower ends of the transposition cylinders 110 are arranged with symmetrical beveled surfaces, the two ends of the support plate 102 are respectively arranged at the lower end of the top beveled surfaces of the two groups of transposition cylinders 110, and the two ends of the limit plate 103 are respectively located at the higher end of the bottom beveled surfaces of the two groups of transposition cylinders 110;

[0038] During the specific operation, the soft ceramic plate is first placed on the surface of the supporting plate 102, and then the motor 112 is started to drive one set of the transposition cylinder 110 and the transmission wheel 111 to rotate, and under the action of the transmission belt, the other set of the transposition cylinder 110 and the transmission wheel 111 are forced to rotate synchronously, and the two sets of transposition cylinders 110 rotate at the same time, and the supporting plate 102 and the limiting plate 103 are respectively pressed by the inclined surfaces of the upper and lower ends of the two sets of transposition cylinders 110, so as to force the supporting plate 102 and the limiting plate 103 to move up and down relative to each other;

[0039] When the two ends of the support plate 102 slide to the lower end of the top inclined surface of the two groups of transposition cylinders 110, and the limiting plate 103 slides to the higher end of the bottom inclined surface of the two groups of transposition cylinders 110, the support plate 102 moves downward and the limiting plate 103 moves upward, and a plurality of groups of wedge-shaped abutting frames 109 extend upward to the top surface of the support plate 102, and jointly press and limit the frame of the soft ceramic plate to assist in straightening, so as to reduce the displacement of the soft ceramic plate and cause the position disorder of the color spraying pattern;

[0040] When the two ends of the supporting plate 102 slide to the higher end of the top inclined surface of the two groups of transposition cylinders 110 and the limiting plate 103 slides to the lower end of the bottom inclined surface of the two groups of transposition cylinders 110, the supporting plate 102 moves upward and the limiting plate 103 moves downward, the spring coil 107 and the spring coil 2 108 are compressed, and the several groups of wedge-shaped abutment frames 109 return downward and lose the limitation on the frame of the soft ceramic plate. At the same time, as the supporting plate 102 is lifted, the straightened soft ceramic plate is moved to the lower end of the color spraying mechanism 2, and the distance between the color spraying mechanism 2 and the surface of the soft ceramic plate is shortened, which is conducive to the subsequent color spraying;

[0041] The color spraying mechanism 2 includes a concave-shaped positioning frame 201, which is located at the top of the L-shaped base 101 and at the upper end of the supporting plate 102. The positioning frame 201 is rotatably connected with a threaded rotating rod 1 202 at the front and rear ends, and one end of the threaded rotating rod 1 202 extends to the outside of the positioning frame 201 and is fixedly installed with a transmission wheel 203. The two groups of transmission wheels 203 are commonly sleeved with a transmission belt on the outside, and one end of one group of threaded rotating rods 1 202 away from the transmission wheel 203 is provided with a motor 204. The two groups of threaded rotating rods 1 202 are commonly slidably connected with a sliding frame 205 on the outside, and a sprayer is fixedly installed on one side of the sliding frame 205 through a machine base;

[0042] When spraying colored dots, the color spray machine is located on one side of the surface of the soft magnetic board. When the color spray machine is started, the motor 204 is started to drive one group of threaded rotating rods 1 202 and the transmission wheel 2 203 to rotate. Under the transmission action of the transmission belt, the other group of threaded rotating rods 1 202 and the transmission wheel 2 203 are driven to rotate synchronously. The two groups of threaded rotating rods 1 202 jointly push the sliding frame 205 and the color spray machine to move in a straight line, and the color spray machine is used to spray the surface of the soft magnetic board.

[0043] Example 2: Please refer to Figure 5 - Figure 7As shown, the bottom surface of the slide frame 205 is provided with an open groove between the two groups of threaded rotating rods 1 202, and the slide frame 205 is rotatably connected with the threaded rotating rod 206 inside, the front end of the threaded rotating rod 206 extends to the outside of the slide frame 205 and is fixedly installed with a steering gear 207, the outer thread of the threaded rotating rod 206 is threadedly sleeved with a push frame 208, the outer surface of the push frame 208 is sleeved with a rectangular sleeve frame 209, and the bottom of the rectangular sleeve frame 209 extends to 3 cm from the bottom of the slide frame 205, and a damping spring shock absorbing ring 210 is commonly provided between the bottom surface of the push frame 208 and the inner wall of the bottom of the rectangular sleeve frame 209;

[0044] The color inkjet mechanism 2 also includes a motor 3 211, which is arranged at the front end of the opening side of the positioning frame 201, and the output end of the motor 3 211 extends to the inside of the positioning frame 201 and is fixedly installed with a guide rod 212, and the outside of the guide rod 212 is laterally slidably connected with a directional gear 213, and the directional gear 213 is meshed and arranged at the bottom of the steering gear 207, and a side baffle is fixedly installed outside the guide rod 212 and located at the directional gear 213;

[0045] After several sprayings, the paint on the surface of the soft magnetic plate is dry. At this time, the color spray machine is turned off, and the motor 3 211 is started to drive the guide rod 212 and the directional gear 213 to rotate. The directional gear 213 is engaged with the steering gear 207 to force the steering gear 207 and the threaded rotating rod 206 to rotate, and push the push frame 208 and the rectangular sleeve frame 209 to move back and forth. The rectangular sleeve frame 209 contacts and rubs against the surface of the soft magnetic plate, so as to facilitate the polishing of the color spraying area on the surface of the soft magnetic plate. At the same time, the sliding frame 205 moves together to realize the horizontal and vertical polishing of the soft magnetic plate surface by the rectangular sleeve frame 209, which is conducive to uniform polishing of the soft magnetic plate surface and further improves the color spraying efficiency of the soft magnetic plate.

[0046] It is worth noting that due to the irregular surface of some soft ceramic panels, when the rectangular frame 209 slides along the surface of the soft ceramic panel and passes through the protruding area, the bottom of the rectangular frame 209 is pushed upward, and the damping spring shock absorber ring 210 is compressed. When it passes the protruding area, it is reset under the rebound force of the damping spring shock absorber ring 210. By adaptively polishing the surface of the soft ceramic panel, the hard pressure and friction between the polished surface of the rectangular frame 209 and the protruding position of the soft ceramic panel surface are reduced, which forces the color dots to be worn through, thereby further improving the color dot spraying quality of the soft magnetic product.

[0047] Example 3: Please refer to Figure 1 As shown, the present invention also discloses a spraying process of a multi-axis positioning color point spraying device for soft porcelain product texture, comprising the following steps:

[0048] S1: soft ceramic plate positioning and limiting process, the soft ceramic plate with a clean surface is sent to the color spraying equipment, the soft ceramic plate is placed on the surface of the supporting plate 102, and then the motor 112 is started, and the two groups of transposition cylinders 110 rotate simultaneously, and the supporting plate 102 and the limiting plate 103 are respectively pressed by the inclined surfaces of the upper and lower ends of the two groups of transposition cylinders 110, thereby forcing the supporting plate 102 and the limiting plate 103 to move up and down relative to each other. When the supporting plate 102 moves downward and the limiting plate 103 moves upward, a plurality of groups of wedge-shaped abutting frames 109 extend upward to the top surface of the supporting plate 102 respectively, and jointly press and limit the frame of the soft ceramic plate to assist in straightening. When the supporting plate 102 moves upward and the limiting plate 103 moves downward, the frame of the soft ceramic plate loses its limit and moves toward the color spraying mechanism 2.

[0049] S2: Multiple spraying operation of soft ceramic plate, and then start the color spraying machine and start the motor 204 at the same time, the motor 2 drives the two sets of threaded rotating rods 1 202 to rotate, and the two sets of threaded rotating rods 1 202 jointly push the sliding frame 205 and the color spraying machine to move linearly, and use the color spraying machine to spray the surface of the soft ceramic plate evenly, and use the color spraying mechanism to spray the surface of the soft ceramic plate repeatedly;

[0050] S3: Fine grinding of the color dots on the sprayed surface of the soft ceramic plate. After the color sprayed area on the surface of the soft ceramic plate is air-dried, the color spray machine is turned off, and the motor 3 211 is started to drive the guide rod 212 and the directional gear 213 to rotate. The directional gear 213 is meshed with the steering gear 207 to force the threaded rotating rod 206 to rotate, and push the push frame 208 and the rectangular sleeve frame 209 to move back and forth. The rectangular sleeve frame 209 contacts and rubs against the surface of the soft magnetic plate, so as to facilitate the grinding of the color sprayed area on the surface of the soft magnetic plate; and the rectangular sleeve frame 209 is coordinated with the movement of the sliding frame 205 to realize the horizontal and vertical color dots grinding on the surface of the soft magnetic plate by the rectangular sleeve frame 209;

[0051] S4: After spraying and polishing, take out the processed soft ceramic plate product.
