Description

Technical Field

[0001] This utility model relates to the field of toy coloring technology, specifically a model partial coloring structure. Background Technology

[0002] In the production of toy models, surface spraying is a key process for reproducing the colors of the original anime artwork and improving the product's appearance quality. To achieve localized spraying, existing technologies typically use custom-made baffles with spray nozzles. This allows the sprayed pigment to adhere to designated areas of the toy model through the nozzles, while the other parts of the model are shielded by the baffle to prevent dye from adhering.

[0003] Due to the wide variety of toy models, and the complexity and irregular shapes of some models, each model requires a custom-designed and customized baffle. However, this customized baffle approach has several drawbacks: first, it has a long production cycle, with significant time spent designing and manufacturing baffles for each model, severely impacting production efficiency; second, it is costly, as baffles for complex and irregularly shaped models require more resources, leading to a substantial increase in production costs; and third, it has poor adaptability, as customized baffles are difficult to reuse, requiring redesign when the model's style changes, further wasting time and money. These problems make it difficult for existing technologies to meet the requirements of efficient and low-cost production when dealing with the diverse and complex localized painting needs of toy models. Utility Model Content

[0004] This utility model addresses the technical problems existing in the prior art by providing a model partial coloring structure to solve the problem that the existing technology is unable to meet the requirements of efficient and low-cost production when dealing with the partial painting needs of diverse and complex toy models.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A local coloring structure for a model, comprising:

[0006] frame;

[0007] A load-bearing compartment, which is mounted on the frame;

[0008] The space frame is placed inside the bearing chamber;

[0009] The model to be painted is placed on a space frame;

[0010] A negative pressure assembly, which is mounted on the frame, is used to blow negative pressure airflow into the bearing chamber;

[0011] A shielding component, which is detachably connected to the top of the carrying bin and is used to close the top opening of the carrying bin. Among them, the shielding component includes a first frame in a square shape with a hole in the middle, a second frame in a square shape with a hole in the middle, and a heat shrink film. The heat shrink film is located between the first frame and the second frame, and the second frame is detachably connected to the top of the carrying bin;

[0012] A hot air gun, which is arranged on the rack.

[0013] The beneficial effects of the present utility model are as follows:

[0014] 1). Through the negative pressure component, the heat shrink film is tightly adhered to the surface of the model in this coloring structure. Then, the heat shrink film is heated by the hot air gun to shrink and wrap according to the contour of the model. There is no need to customize a dedicated baffle for each model, which reduces the production preparation time and cost, and is suitable for the spraying requirements of complex and irregularly shaped models. Secondly, under the action of negative pressure and hot air, the heat shrink film can firmly wrap the model, ensuring that the model does not shift during the coloring process, thereby improving the stability of spraying and the product quality.

[0015] 2). In addition, according to the coloring position of the local part of the model, the heat shrink film covering the spraying area can be cut to form a spraying port, which can achieve high-precision positioning spraying of the local area of the model, ensuring the appearance consistency. Finally, as a general consumable, the heat shrink film has strong adaptability and low cost, which can further improve the production flexibility and economic benefits. In summary, with a simplified process flow and low-cost material application, this device significantly improves the efficiency and quality of local spraying of toy models.

[0016] Based on the above technical solutions, the present utility model can be further improved as follows.

[0017] Further, the negative pressure component includes a negative pressure pipe and a vacuum pump, and the vacuum pump is fixed on the rack.

[0018] Further, one end of the negative pressure pipe is fixed on the output end of the vacuum pump, and the other end of the negative pressure pipe is connected to the inside of the carrying bin.

[0019] The beneficial effect of adopting the above further scheme is that when the vacuum pump is started, the inside of the carrying bin is evacuated through the negative pressure pipe to form a negative pressure environment. At this time, the heat shrink film covering the top of the carrying bin and clamped by the first frame and the second frame is pulled by the negative pressure air flow and adheres to the inside of the carrying bin, and then tightly wraps the surface of the model placed on the grid, effectively promoting the heat shrink film to adhere to the outside of the model initially.

[0020] Further, a first card slot in a square shape with a hole in the middle is opened at the top of the second frame.

[0021] The beneficial effect of adopting the above further solution is that the first frame can firmly clamp the heat-shrinkable film into the first card slot, effectively achieving the clamping and fixing of the heat-shrinkable film. At the same time, the square-shaped design of the first card slot enhances the fitting tightness between the first frame and the second frame, improves the airtightness at the connection between the two, and reduces gas leakage in the negative pressure environment.

[0022] Further, a second card slot in a square shape is provided at the top of the bearing bin.

[0023] The beneficial effect of adopting the above further solution is that the second frame can be embedded into the second card slot of the bearing bin, realizing the stable limit of the second frame on the bearing bin, facilitating the quick installation and disassembly of the second frame, and enhancing the modular characteristics of the device.

[0024] Further, the heat-shrinkable film adopts a transparent heat-shrinkable film.

[0025] The beneficial effect of adopting the above further solution is that by using a transparent heat-shrinkable film, the staff can clearly observe the coloring position of the model, facilitating the accurate cutting of the spraying opening on the heat-shrinkable film, ensuring the accuracy and consistency of the spraying area, and avoiding cutting deviation caused by blocked vision.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The principles and features of the present utility model are described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0034] In the production of toy models, surface spraying is a key process for reproducing the colors of the original anime artwork and improving the product's appearance quality. To achieve localized spraying, existing technologies typically use custom-made baffles with spray nozzles. This allows the sprayed pigment to adhere to designated areas of the toy model through the nozzles, while the other parts of the model are shielded by the baffle to prevent dye from adhering.

[0035] Due to the wide variety of toy models, and the complexity and irregular shapes of some models, each model requires a custom-designed and customized baffle. However, this customized baffle approach has several drawbacks: firstly, it has a long production cycle, as designing and processing baffles for each model consumes a significant amount of time, severely impacting production efficiency; secondly, it is costly, as the production of baffles for complex and irregularly shaped models requires more resources, leading to a substantial increase in production costs; and thirdly, it has poor adaptability, as customized baffles are difficult to reuse, and when the model style changes, the baffles must be redesigned, further wasting time and money. These problems make it difficult for existing technologies to meet the requirements of efficient and low-cost production when dealing with the localized painting needs of diverse and complex toy models. Therefore, the inventor has proposed a model localized painting structure to solve these problems.

[0036] The present invention provides the following preferred embodiments.

[0037] like Figures 1-5 As shown, a local coloring structure for a model includes:

[0038] Rack 10;

[0039] The load-bearing compartment 20 is mounted on the frame 10.

[0040] Space frame 30 is placed inside bearing chamber 20;

[0041] Model 40, to be painted, is placed on the space frame 30;

[0042] Negative pressure component 50, which is mounted on the frame 10, is used to blow negative pressure airflow into the bearing chamber 20;

[0043] A shielding assembly 60 is detachably connected to the top of the carrying chamber 20 to close the top opening of the carrying chamber 20. The shielding assembly 60 includes a first frame 601 in the shape of a U-shape, a second frame 602 in the shape of a U-shape, and a heat shrink film 603. The heat shrink film 603 is located between the first frame 601 and the second frame 602. The second frame 602 is detachably connected to the top of the carrying chamber 20.

[0044] A hot air gun is mounted on the frame 10.

[0045] This coloring structure uses a negative pressure component 50 to make the heat-shrinkable film 603 closely adhere to the surface of the model 40. Then, a hot air gun is used to heat the heat-shrinkable film 603 to shrink and wrap according to the contour of the model 40. There is no need to customize a special baffle for each model 40, which reduces the production preparation time and cost and is applicable to the spraying requirements of complex-shaped models 40. Secondly, under the action of negative pressure and hot air, the heat-shrinkable film 603 can firmly wrap the model 40, ensuring that the model 40 does not shift during the coloring process, thereby improving the stability of spraying and product quality;

[0046] In addition, according to the coloring position of the local part of the model 40, the heat-shrinkable film 603 covering the spraying area can be cut to form a spraying port, which can achieve high-precision positioning spraying of the local area of the model 40 and ensure the appearance consistency. Finally, as a general consumable, the heat-shrinkable film 603 has strong adaptability and low cost, which can further improve the production flexibility and economic benefits. In summary, this device significantly improves the efficiency and quality of local spraying of toy models 40 with a simplified process flow and low-cost material application.

[0047] In this embodiment, as Figures 1-5 shown, the negative pressure component 50 includes a negative pressure pipe 501 and a vacuum pump 502. The vacuum pump 502 is fixed on the frame 10. One end of the negative pressure pipe 501 is fixed on the output end of the vacuum pump 502, and the other end of the negative pressure pipe 501 is connected to the inside of the bearing chamber 20;

[0048] After the vacuum pump 502 is started, the inside of the bearing chamber 20 is evacuated through the negative pressure pipe 501 to form a negative pressure environment. At this time, the heat-shrinkable film 603 covered on the top of the bearing chamber 20 and clamped by the first frame 601 and the second frame 602 is pulled by the negative pressure air flow and adheres to the inside of the bearing chamber 20, and then tightly wraps around the surface of the model 40 placed on the grid 30, effectively promoting the heat-shrinkable film 603 to adhere to the outside of the model 40 initially.

[0049] In this embodiment, as Figures 1-5 shown, the top of the second frame 602 is provided with a first card slot 70 in a square shape with a hole in the middle, so that the first frame 601 can firmly clamp the heat-shrinkable film 603 into the first card slot 70, effectively realizing the clamping and fixing of the heat-shrinkable film 603. At the same time, the square-with-a-hole design of the first card slot 70 enhances the tightness of the fit between the first frame 601 and the second frame 602, improves the airtightness at the connection between the two, and reduces the gas leakage under the negative pressure environment.

[0050] In this embodiment, as Figures 1-5As shown in the figure, a second card slot 80 in the shape of a double-square is provided at the top of the bearing bin 20, enabling the second frame 602 to be embedded in the second card slot 80 of the bearing bin 20, achieving stable positioning of the second frame 602 on the bearing bin 20, facilitating quick installation and disassembly of the second frame 602, and enhancing the modular characteristics of the device. In addition, in order to further improve airtightness, rubber pads are added to the bottom of the first frame 601 and the bottom of the second frame 602.

[0051] In this embodiment, as Figures 1-5 shown, the heat-shrinkable film 603 is a transparent heat-shrinkable film 603. By using a transparent heat-shrinkable film 603, staff can clearly observe the coloring positions of the model 40, facilitating precise cutting of spraying openings on the heat-shrinkable film 603, ensuring the accuracy and consistency of the spraying area, and avoiding cutting deviations caused by blocked vision.

[0052] The specific working process of the present utility model is as follows:

[0053] (1) Preparation before spraying

[0054] First, place the model 40 to be colored on the grid 30 inside the bearing bin 20.

[0055] (2) Initially wrapping the model 40

[0056] After preparation, when the vacuum pump 502 is started, the inside of the bearing bin 20 is evacuated through the negative pressure pipe 501 to form a negative pressure environment. At this time, the heat-shrinkable film 603 covered on the top of the bearing bin 20 and clamped by the first frame 601 and the second frame 602 is pulled by the negative pressure air flow and adheres to the inside of the bearing bin 20, and then tightly wraps around the surface of the model 40 placed on the grid 30, effectively promoting the heat-shrinkable film 603 to adhere to the outside of the model 40 initially.

[0057] (3) Further wrapping the model 40

[0058] Then use a hot air gun to heat to make the heat-shrinkable film 603 shrink and wrap according to the contour of the model 40.

[0059] (4) Cutting the spraying opening

[0060] When the heat-shrinkable film 603 wraps the model 40, according to the coloring positions of the local parts of the model 40, cut the spraying opening on the heat-shrinkable film 603 covering the spraying area, and high-precision positioning spraying of the local area of the model 40 can be achieved.

[0061] The above is only the preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
