[0001] The present invention belongs to the technical field of spraying, and specifically relates to a spraying and drying device for resin handicraft processing and its processing method. Background Art

[0002] In the field of modern process production, resin handicrafts, with their unique shapes, rich colors, and excellent textures, are widely used in multiple fields such as decoration and collection, and the market demand continues to grow. In the processing process of resin handicrafts, spraying and drying is a crucial link, directly affecting the appearance quality and production efficiency of products.

[0003] Currently, common spraying and drying equipment for resin handicrafts mostly adopts independent spraying devices and drying devices. After spraying, it is necessary to manually transfer the handicrafts to the drying station, with a low degree of automation. This not only consumes a large amount of labor and time costs, but also easily causes damage to the handicrafts during the transfer process. At the same time, the existing spraying equipment has obvious defects in nozzle cleaning. Generally, the nozzle is disassembled and then soaked, which is not only cumbersome and inefficient in operation, but also difficult to ensure the cleaning effect. Residual spraying raw materials are extremely likely to cause nozzle blockage, affecting the accuracy and quality of subsequent spraying operations, and increasing equipment maintenance costs and downtime.

A sliding rod is installed at the bottom of the arched bracket. The sliding rod is slidably arranged in a strip-shaped groove formed on the surface of the pressing arm. A ejector rod is installed at the bottom of the sliding rod. The ejector rod is attached to the surface of the shielding plate.

[0015] As a preferred embodiment of the present invention, a processing method for resin handicrafts comprises the following steps: Step 1: Open the sealing door, place the handicraft through the notch onto the turntable, and close the sealing door. Then, drive the handicraft to rotate through the driving source in the painting table, and spray the pigment from the nozzle on the spray head onto the handicraft through the spraying system, finally completing the painting operation; Step 2: Start the driving motor. Drive the bottom disc to rotate through the driving motor. The spiral wire groove on the disc drives the extrusion column to slide relatively, and the bottom push rod is moved through the ramp. The movement of the push rod drives the arched bracket and the ejector rod to move downward. The ejector rod presses the shielding plate to turn downward. Finally, the end face of the shielding plate fits against the side wall of the ejector rod. At this time, the cleaning box is in an open state; Step 3: During the downward movement of the arched bracket, the pressing arm is squeezed to rotate, thereby driving the spray head and the nozzle to turn.

And during the drying process, the handicraft is driven to rotate through the turntable to make the drying uniform. And during the rotation of the turntable, the friction groove on the turntable drives the friction wheel. At this time, the friction wheel drives the cleaning roller to rotate, thereby cleaning the spray head for the second time, thus reducing the possible clogging phenomenon of the spray head; Step 6: After drying is completed, the disc and the spray head are driven to reset, and the spray head is removed from the cleaning liquid. At this time, the surface of the spray head is dried through the remaining drying temperature inside the protective cover, reducing the impact on the subsequent spraying of different raw materials.

[0016] The present invention has the following beneficial effects compared with the prior art: Through the ingenious design of the automated process and the temperature coordination mechanism, the present invention achieves efficient anti-clogging of the nozzle. After the spraying is completed, under the drive of the automated process, the extrusion column not only rotates the heating plate to the drying station, but also through the linkage of the push rod, flips the nozzle and immerses it in the cleaning liquid in the cleaning tank for soaking and cleaning, so that it is fully dissolved, effectively reducing the risk of clogging; during the drying process, the rising temperature in the protective cover raises the temperature of the cleaning liquid through heat transfer, accelerating the dissolution of the residual raw materials; after the drying operation is completed, the nozzle is removed from the cleaning liquid, and the residual drying temperature in the protective cover immediately dries the surface of the nozzle, avoiding the drying and blockage of the cleaning liquid or raw material residues. All links in the whole process are closely coordinated, from cleaning, temperature assistance to residual treatment, which effectively reduces the risk of nozzle clogging and lays a good foundation for subsequent spraying operations.

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. The following embodiments are used to illustrate the present invention.

[0021] Embodiment 1, as Figures 1 to 8 shown, a painting and drying device for resin handicraft processing includes a painting table 1 and a protective cover 11 installed on its surface, and a turntable 14 is rotatably installed on the painting table 1. By setting the turntable 14, the handicraft can rotate in all directions during painting, ensuring uniform coverage of the pigment, avoiding painting dead angles, and effectively improving the integrity and aesthetics of the painting effect.

[0022] A pair of nozzles 2 for painting are rotatably installed on the painting table 1, and nozzles 21 are installed on the nozzles 2. A pressing arm 22 is installed at the rotation center of the nozzles 2; the double-nozzle design can perform painting of different colors or patterns simultaneously, greatly improving the painting efficiency and meeting diverse process requirements.

[0023] A cleaning tank 23 for dissolving painting raw materials is installed on the painting table 1. A shutter 231 connected by a torsion spring is installed on the cleaning tank 23, and a cleaning roller 3 and a friction wheel 32 connected coaxially are installed on the cleaning tank 23. The friction wheel 32 is adapted to the side wall of the turntable 14; the cleaning tank 23 can clean the nozzles in time, prevent the residual pigment from clogging the nozzles, extend the service life of the nozzles, and reduce the equipment maintenance cost.

[0024] A pressing column 422 that slides horizontally is installed on the protective cover 11. The pressing column 422 presses the heating plate 43 that is rotatably installed at the bottom of the protective cover 11, causing it to move to the drying station, and increasing the cleaning temperature to improve the cleaning efficiency. A slope 245 is provided on the side wall of the pressing column 422. The slope 245 is used to press the push rod 243 that slides on the pressing arm 22 to slide, pressing the shielding plate 231 to open the cleaning tank 23 and rotating its nozzle 2 into the cleaning tank 23. The automatic movement design of the heating plate 43 realizes rapid drying after spraying, reduces manual intervention, improves the degree of automation and work efficiency; at the same time, by increasing the cleaning temperature, the dissolution rate of the cleaning liquid for the residual pigment is accelerated, significantly improving the cleaning efficiency.

[0025] As Figures 1 to 8 shown, in the specific implementation, four support legs 13 are installed at the bottom of the spraying table 1. Reinforcing ribs 131 with different heights are installed on adjacent support legs 13. A fixing frame 111 is installed on the top of the spraying table 1. The protective cover 11 is sleeved on the side wall of the fixing frame 111, and the protective cover 11 and the fixing frame 111 are connected by screwing bolts. A feeding notch 112 is opened on the protective cover 11. The reinforcing ribs 131 enhance the structural stability of the spraying table, making it not easily deformed during long-term use and ensuring the reliability of equipment operation; the bolt connection method between the protective cover and the fixing frame is convenient for disassembly and maintenance, and the feeding notch facilitates the rapid picking and placing of handicrafts.

[0026] As Figures 1 to 8 shown, further, a pair of guide rails 121 are installed on the protective cover 11. A pair of sealing doors 12 are slidably arranged on the pair of guide rails 121. An observation window 122 is installed on the sealing door 12, and tempered glass is embedded in the observation window 122. A handle 123 is installed on the sealing door 12, and an anti-slip sleeve is installed on the surface of the handle 123. The design of the sealing door in cooperation with the guide rail can effectively form a closed space, prevent pigment splashing during spraying, and protect the working environment and the health of operators; the tempered glass observation window is convenient for observing the internal spraying and drying conditions in real time, without the need to frequently open the sealing door, avoiding affecting the work process and the internal environment; the design of the anti-slip sleeve improves the comfort and convenience of operators when opening and closing the sealing door.

[0027] Example 2, different from the above example and this example: As Figures 1 to 8As shown in the figure, a connecting frame 211 is installed on the outer shell of the nozzle 2. The connecting frame 211 is L-shaped. A positioning frame 212 is installed on the side wall of the cleaning tank 23. A synchronous shaft 222 is rotatably installed on the positioning frame 212. The side wall of the synchronous shaft 222 is connected to the side wall of the pressing arm 22. The synchronous shaft 222 is connected to the rotation center of the connecting frame 211. And a connecting pipe 213 is installed on the nozzle 2. And the connecting pipe 213 is a flexible pipe. The connecting pipe 213 is connected to the spraying system. The spraying system is a prior art, and its working principle will not be elaborated here. The cooperation of the L-shaped connecting frame and the synchronous shaft ensures the stability and accuracy of the nozzle flipping process, enabling the nozzle to accurately immerse into the cleaning tank for cleaning; the flexible connecting pipe provides a flexible moving space for the rotation of the nozzle while ensuring the pigment transportation.

[0028] As Figures 1 to 8 shown, in the specific embodiment, a fence 141 is installed on the side wall of the turntable 14. A friction groove 142 is opened inside the fence 141. The friction groove 142 is in mutual fit with the friction wheel 32. And a connecting shaft 321 is installed at the rotation center of the friction wheel 32. And the connecting shaft 321 penetrates through the cleaning tank 23. The connecting shaft 321 is connected to the cleaning roller 3. And a brush 31 is installed on the cleaning roller 3. The brush 31 corresponds to the surface of the flipped nozzle 21. The cleaning tank 23 is installed in the installation groove 232 opened on the surface of the spraying table 1. The design of the fence and the friction groove cleverly utilizes the power of the turntable rotation to drive the cleaning roller to rotate, realizing the secondary cleaning of the nozzle, without an additional power source, energy-saving and environment-friendly; at the same time, this structural design is compact, makes full use of the internal space of the equipment, and improves the overall performance of the equipment.

[0029] As Figures 1 to 8 shown, further, a driving motor 41 is installed outside the protective cover 11. A disc 4 is installed on the inner side wall of the protective cover 11. The output end of the driving motor 41 is connected to the disc 4. A spiral wire groove 42 is opened on the surface of the disc 4. A slider 421 is slidably arranged on the spiral wire groove 42. The side wall of the slider 421 is connected to the side wall of the extrusion column 422. A guiding ball 244 is installed at the top of the push rod 243. The guiding ball 244 is in fit with the side wall of the extrusion column 422. The cooperation of the driving motor, the disc and the spiral wire groove realizes the linkage of multiple components through simple mechanical transmission, simplifies the equipment structure, and reduces the probability of faults; the guiding ball reduces the friction between the push rod and the extrusion column, makes the transmission process smoother, and improves the stability of the equipment operation.

[0030] Embodiment 3, the difference from the above embodiment in this embodiment is: As Figures 1 to 8As shown in the figure, a guide rod 423 is movably arranged through the inside of the extrusion column 422. Both ends of the guide rod 423 are installed on the side wall of the protective cover 11. A protrusion 433 is installed on the side wall of the extrusion column 422. A rocker arm 431 is slidably arranged on the protrusion 433. One end of the rocker arm 431 is connected to the heating plate 43, and the other end of the rocker arm 431 is rotatably installed with a mounting seat 434, and the mounting seat 434 is welded to the top of the protective cover 11. A linear through groove 432 is formed on the rocker arm 431, and the linear through groove 432 is connected to the protrusion 433. The heating plate 43 is connected to the drying system. The guide rod ensures the linearity and stability of the sliding of the extrusion column, preventing it from shifting during movement; the cooperation between the protrusion and the rocker arm realizes the automatic flipping and positioning of the heating plate, enabling the heating plate to quickly reach the drying station and improving the drying efficiency.

[0031] As Figures 1 to 8 shown, in the specific implementation manner, a limit seat 246 is fixedly installed on the side wall of the protective cover 11. A push rod 243 is movably inserted into the inside of the limit seat 246. A baffle 247 is installed on the push rod 243. A return spring 248 is sleeved on the push rod 243. One end of the return spring 248 is clamped on the baffle 247, and the other end of the return spring 248 is clamped on the limit seat 246. An arched bracket 24 is installed at the bottom of the push rod 243. A slide rod 241 is installed at the bottom of the arched bracket 24. The slide rod 241 is slidably arranged in a strip-shaped groove 221 formed on the surface of the pressing arm 22. A ejector rod 242 is installed at the bottom of the slide rod 241, and the ejector rod 242 is attached to the surface of the shielding plate 231. The return mechanism composed of components such as the limit seat and the return spring ensures that the push rod can automatically return after the operation is completed, prepares for the next work, and improves the automation degree and work continuity of the equipment; at the same time, this structural design ensures the accuracy and reliability of the actions of the nozzle flipping and the cleaning box opening.

[0032] The present invention also discloses a processing method for resin handicrafts, and the steps are as follows: Step 1: Open the sealing door 12, put the handicraft into the turntable 14 from the notch 112, and close the sealing door 12. Then, drive the handicraft to rotate through the drive source in the painting table 1, and spray the pigment from the nozzle 21 on the nozzle 2 onto the handicraft through the spraying system, and finally complete the painting operation; Step 2: Start the drive motor 41, drive the bottom disc 4 to rotate through the drive motor 41, and the spiral wire groove 42 on the disc 4 drives the extrusion column 422 to slide relatively. And the bottom push rod 243 is pushed to move through the slope 245. The movement of the push rod 243 drives the arched bracket 24 and the ejector rod 242 to move downward. The ejector rod 242 presses the shielding plate 231 to flip downward. Finally, the end face of the shielding plate 231 is attached to the side wall of the ejector rod 242. At this time, the cleaning box 23 is in an open state; Step 3: During the downward movement of the arched support 24, the squeezing arm 22 rotates, thereby driving the nozzle 2 and the nozzle 21 to flip. Eventually, the nozzle 2 is immersed in the cleaning tank 23 filled with cleaning liquid, thereby soaking and cleaning the raw materials remaining on the surface of the nozzle 2, reducing the occurrence of blockage; Step 4: During the sliding process of the extrusion column 422, the protrusion 433 on the side wall of the extrusion column 422 slides on the rocker arm 431, driving the heating plate 43 originally in a horizontal state to rotate to a specified position, and then heating the sprayed raw materials by heating the heating plate 43 through the drying system; Step 5: During the drying process, the temperature inside the protective cover 11 rises, thereby driving the temperature of the cleaning liquid to increase through heat transfer, thereby improving the cleaning efficiency. And during the drying process, the handicraft is driven to rotate by the turntable 14 to make the drying uniform. And during the rotation of the turntable 14, the friction groove 142 on the turntable 14 drives the friction wheel 32. At this time, the friction wheel 32 drives the cleaning roller 3 to rotate, thereby performing secondary cleaning on the nozzle 2, thus reducing the possible blockage phenomenon of the nozzle 2; Step 6: After drying is completed, the driving disc 4 and the nozzle 2 are reset, and the nozzle 2 is removed from the cleaning liquid. At this time, the surface of the nozzle 2 is dried by the residual drying temperature inside the protective cover 11, reducing the impact on subsequent spraying of different raw materials.

[0033] The implementation principle of a spraying and drying device for resin handicraft processing of the present invention is as follows: When it is necessary to spray a resin handicraft, the operator first holds the handle 123 with an anti-slip sleeve on the sealing door 12 and slides along the guide rail 121 to open the sealing door 12, and puts the handicraft into the turntable 14 on the spraying table 1 from the notch 112 on the protective cover 11, and then closes the sealing door 12. Doing so can form a relatively closed space to prevent the paint from splashing into the surrounding environment during spraying, which not only ensures the cleanliness of the workplace but also reduces the potential harm of the paint to the operator.

[0034] The driving source in the spraying table 1 drives the turntable 14 to start rotating, so that the handicraft can receive spraying in all directions. At the same time, the spraying system transports the paint to the nozzle 21 through the connecting pipe 213 on the nozzle 2 (the spraying system is a prior art, which is not shown in the figure and the specific working principle will not be elaborated here), and then evenly sprays it onto the surface of the rotating handicraft. Then the operator can observe the spraying situation in real time through the observation window 122 with embedded tempered glass on the sealing door 12 and make adjustments in time.

[0035] After the spraying operation is completed, start the drive motor 41 outside the protective cover 11. The drive motor 41 drives the disk 4 connected to its output end to rotate. The spiral groove 42 on the surface of the disk 4 will cause the slider 421 sliding thereon to drive the extrusion column 422 to slide horizontally in the protective cover 11 along the guide rod 423.

[0036] The slope 245 on the side wall of the extrusion column 422 contacts and presses the guide ball 244 at the top of the push rod 243, and the push rod 243 moves downward in the limit seat 246, compressing the return spring 248. The arched bracket 24, the sliding rod 241 and the ejector rod 242 at the bottom of the push rod 243 move downward accordingly. The ejector rod 242 presses the shutter 231 connected to the cleaning tank 23 through a torsion spring, causing it to flip downward, thereby opening the cleaning tank 23. During the downward movement of the arched bracket 24, the sliding rod 241 slides in the strip-shaped groove 221 formed on the surface of the pressure arm 22, squeezing the pressure arm 22 to rotate around the synchronous shaft 222, and then driving the nozzle 2 and the nozzle 21 to flip, so that they are immersed in the cleaning tank 23 filled with the cleaning liquid. Soaking and cleaning can fully dissolve the raw materials remaining on the surface of the nozzle 2 in the cleaning liquid, reducing the possibility of blockage.

[0037] And when the extrusion column 422 slides, the protrusion 433 on its side wall slides in the linear through groove 432 of the rocker arm 431, causing the rocker arm 431 to rotate around the mounting seat 434, and rotating the heating plate 43 originally in a horizontal state to the drying station. The heating plate 43 is connected to the drying system (the drying system is a prior art, which is not shown in the figure and its specific working principle will not be elaborated here), and starts to heat up to heat and dry the raw materials sprayed on the surface of the handicraft.

[0038] During the drying process, the turntable 14 continuously drives the handicraft to rotate, so that the raw materials are evenly heated, avoiding the situation of local incomplete drying or over-drying, ensuring the consistency and stability of the drying effect, and improving the quality of the handicraft. At the same time, the temperature inside the protective cover 11 rises, and the cleaning liquid in the cleaning tank 23 is heated through heat transfer. The heated cleaning liquid can accelerate the dissolution rate of the raw materials remaining on the surface of the nozzle 2, improve the cleaning efficiency, and reduce the cleaning time.

[0039] And during the continuous rotation of the turntable 14, the friction groove 142 in the side wall enclosure 141 thereof is closely attached to the friction wheel 32, driving the friction wheel 32 to rotate. The friction wheel 32 drives the cleaning roller 3 on the cleaning tank 23 to rotate through the connecting shaft 321. The brush 31 on the cleaning roller 3 performs secondary cleaning on the surface of the nozzle 2, further removing stubborn residual raw materials, ensuring the smoothness of the nozzle 2, extending the service life of the nozzle 2, and reducing the maintenance cost of the equipment.

[0040] After the drying operation is completed, the drive motor 41 rotates in reverse, driving the disc 4 to rotate in the reverse direction, so that the extrusion column 422, the nozzle 2 and the heating plate 43 are reset. The nozzle 2 is removed from the cleaning liquid. At this time, the residual drying temperature inside the protective cover 11 can dry the surface of the nozzle 2, avoiding the residual cleaning liquid or raw materials on the surface of the nozzle 2, reducing the influence on the subsequent spraying of different raw materials, and ensuring the accuracy and quality of the spraying of different colors or types of pigments.

10. A method for processing a resin handicraft, characterized in that: The inkjet drying device for processing resin handicrafts according to any one of claims 1 to 9 is used, and the processing method comprises the following steps: Step 1: Open the sealed door (12), place the craftwork through the notch (112) onto the turntable (14), and close the sealed door (12), then drive the craftwork to rotate through the driving source in the spray painting table (1), and spray the paint from the nozzle (21) on the spray head (2) onto the craftwork through the spray painting system, and finally complete the spray painting operation; Step 2: Start the drive motor (41), and drive the bottom disc (4) to rotate through the drive motor (41), and the spiral groove (42) on the disc (4) drives the extrusion column (422) to slide relatively, and squeezes the bottom push rod (243) to move through the slope (245), and the push rod (243) moves to drive the arch support (24) and the push rod (242) to move downward, and the push rod (242) squeezes the shield plate (231) to flip downward, and finally the end face of the shield plate (231) is in contact with the side wall of the push rod (242), and the cleaning box (23) is in an open state; Step 3: During the downward movement of the arch support (24), the squeezing arm (22) rotates, thereby driving the nozzle (2) and the nozzle (21) to flip, and finally immersing the nozzle (2) in a cleaning tank (23) filled with cleaning liquid, thereby immersing and cleaning the raw materials remaining on the surface of the nozzle (2), thereby reducing the occurrence of blockage; Step 4: During the sliding process of the extrusion column (422), the protrusion (433) on the side wall of the extrusion column (422) slides on the rocker arm (431), driving the heating plate (43) which was originally in a horizontal state to rotate to a specified position, and then the heating plate (43) is heated by the drying system to heat and dry the sprayed raw material; Step 5: During the drying process, the temperature inside the protective cover (11) rises, and the temperature of the cleaning liquid is increased through heat transfer, thereby improving the cleaning efficiency. During the drying process, the handicraft is driven to rotate by the turntable (14) so ​​that it is dried evenly. During the rotation of the turntable (14), the friction groove (142) on the turntable (14) drives the friction wheel (32), and the friction wheel (32) drives the cleaning roller (3) to rotate, thereby performing a secondary cleaning of the nozzle (2), thereby reducing the possibility of nozzle blockage. Step 6: After the drying is completed, the driving disc (4) and the nozzle (2) are reset, and the nozzle (2) is removed from the cleaning liquid. At this time, the surface of the nozzle (2) is dried by the residual drying temperature inside the protective cover (11), thereby reducing the impact on the subsequent printing of different raw materials.
