Description

Technical Field

[0001] This application relates to the field of auxiliary equipment for color painting spraying, specifically a pigment drying device for color painting spraying. Background Technology

[0002] In the field of paint spraying, the pigment drying process directly affects the final appearance and durability of the artwork. Currently, hot air drying devices are widely used due to their simple structure and controllable cost. A typical technical solution involves directly aligning the outlet of the hot air blower with the sprayed surface via a pipe, utilizing the convection of the hot airflow to accelerate the evaporation of solvents in the pigment, thus achieving the drying purpose.

[0003] However, when a high-speed hot airflow directly impacts an undried pigment layer, the mechanical impact of the airflow causes physical deformation on the surface of the pigment layer. This manifests as blurred edges of painted lines, misaligned patterns, and pigment buildup in gradient areas. This not only severely affects the artistic expression and yield rate of painted works but also increases rework and repair costs. The limitations of this technology are even more pronounced in high-precision artistic creation or mass production scenarios.

[0004] Therefore, this application provides a pigment drying apparatus for color painting spraying to solve the above-mentioned problems. Utility Model Content

[0005] This application provides a pigment drying device for color painting spraying, which aims to solve the problems mentioned in the background art, such as the physical deformation of the pigment layer caused by direct impact of hot airflow (such as blurred line edges, misaligned pattern textures, and accumulation of color spots in gradient color areas), and the difficulty in balancing drying efficiency and pigment protection.

[0006] To achieve the above objectives, this application provides the following technical solution: a pigment drying device for color painting spraying, including a control box and a hot air blower installed on the control box, wherein the output end of the hot air blower is connected to a corrugated hose;

[0007] To prevent hot air from directly blowing onto the paint in the painting process: an air collector is fixedly installed at the end of the corrugated hose away from the hot air blower. Air guide plates are fixedly connected to both sides of the end of the air collector away from the corrugated hose. A baffle plate is fixedly connected to the output port of the air collector, and the baffle plate corresponds to the slots between the two air guide plates. A handle is fixedly connected to the lower end of the air collector. Through the cooperation of the air collector, air guide plates, and baffle plates, the high-speed hot air generated by the hot air blower is effectively prevented from directly impacting the undried paint layer. This solves the problems of paint deformation and blurred textures caused by traditional direct drying methods. While ensuring drying efficiency, it significantly improves the surface precision and integrity of the painted artwork and reduces rework rates.

[0008] Preferably, to improve the air guiding effect of the air guide plate, the air guide plate is inclined, that is, the air guide plate is inclined towards the middle of the output end of the air collecting hood. The inclined air guide plate significantly enhances the guiding ability of hot airflow, making the originally dispersed hot air more accurately converge towards the middle, optimizing the airflow distribution in the air collecting hood, reducing energy loss, achieving more uniform heat flow output under the same energy consumption, and further improving air guiding efficiency and drying uniformity.

[0009] Preferably, to improve the windproof effect of the baffle plate: the baffle plate is arc-shaped, and the concave arc surface of the baffle plate faces the direction of the corrugated hose. The arc-shaped baffle plate, through its special curved surface structure, produces a gentle reflection and diversion effect on the converging hot airflow, avoiding the airflow turbulence or local eddies that may occur with traditional flat baffle plates. This makes the hot air discharged more smoothly and evenly from the gaps between the sides of the baffle plate and the output end of the air collecting hood, further reducing the impact of the airflow on the pigment surface and improving the protective effect and drying quality.

[0010] Preferably, to facilitate the drying of paint sprayed at different heights, the handle is equipped with a height adjustment mechanism. This mechanism includes a fixed sleeve fitted onto the bottom of the handle and a knurled screw threaded into the top of the fixed sleeve via a threaded hole, with the knurled screw abutting against the outer wall of the handle. Through this height adjustment mechanism, the operator can flexibly adjust the working height of the air collection hood according to the actual height of the paint spraying, eliminating the need for additional equipment or bending over, significantly improving the versatility and ease of use of the device, and adapting to diverse work scenarios.

[0011] Preferably, to facilitate the fixing of the sleeve, both the control box and the hot air blower are fixedly equipped with C-shaped brackets for engaging the sleeve at the end near the corrugated hose, with the two C-shaped brackets arranged vertically. The C-shaped brackets provide a reliable storage and fixing position for the sleeve, preventing the handle and air collector from swinging or falling off when the device is not in use. They also facilitate quick installation and disassembly during operation, improving equipment integration, saving storage space, and optimizing the operation process.

[0012] Preferably, to ensure the stability of the fixed sleeve position: a support plate is fixedly installed on the control box below the C-shaped bracket, and the top of the support plate has a groove for the bottom of the fixed sleeve to be inserted. The combination design of the support plate and the groove provides double stable support for the fixed sleeve, avoiding the shaking or sagging that may occur when it is only clamped by the C-shaped bracket, and ensuring the stability of the air collector hood during storage.

[0013] This application effectively prevents the high-speed hot air generated by the hot air blower from directly impacting the undried pigment layer through the combination of the air collector, air guide plate and air baffle plate. It solves the problems of pigment deformation and blurred texture caused by traditional direct blowing drying method. While ensuring drying efficiency, it significantly improves the surface precision and integrity of the painted works and reduces the rework rate.

[0014] This application, through a height adjustment mechanism, allows operators to flexibly adjust the working height of the air collection hood according to the actual height of the color painting spraying, without the need for additional equipment to raise the hood or bending over to operate, significantly improving the versatility and ease of use of the device, and adapting to diverse operating scenarios.

[0015] The C-type mounting bracket of this application provides a reliable storage and fixing position for the fixed sleeve, preventing the handle and air collector from shaking or falling off when the device is not in use. At the same time, it facilitates quick installation and disassembly during operation, improves equipment integration, saves storage space, and optimizes the operation process.

[0022] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0023] Example 1

[0024] This embodiment provides a pigment drying device for color painting spraying, such as... Figure 1-4As shown, the drying device includes a control box 1 and a hot air blower 2 mounted on the control box 1. A corrugated hose 3 is connected to the output end of the hot air blower 2. To prevent the hot air from directly blowing onto the paint being sprayed, a collector hood 4 is fixedly installed at the end of the corrugated hose 3 away from the hot air blower 2. Air guide plates 41 are fixedly connected to both sides of the end of the collector hood 4 away from the corrugated hose 3. A baffle plate 42 is fixedly connected to the output end of the collector hood 4, and the slots between the baffle plate 42 and the two air guide plates 41 correspond to each other. A handle 43 is fixedly connected to the lower end of the collector hood 4. Through the cooperation of the collector hood 4, the air guide plates 41, and the baffle plate 42, the high-speed hot air generated by the hot air blower 2 is effectively prevented from directly impacting the undried paint layer. This solves the problems of paint deformation and blurred textures caused by traditional direct drying methods. While ensuring drying efficiency, it significantly improves the surface precision and integrity of the painted artwork and reduces the rework rate. The hot air generated by the hot air blower 2 enters the air collecting hood 4 through the corrugated hose 3. The air guide plates 41 on both sides guide the airflow to gather in the middle of the output end of the air collecting hood 4, forming a converging trend. The baffle plate 42 is located at the output end port and is opposite to the slot of the air guide plate 41. It blocks the direct airflow in the middle and forces the hot air to be evenly discharged from the gap between the output end of the air collecting hood 4 and the baffle plate 42 (i.e., the two sides area), forming a gentle ring-shaped hot airflow that indirectly acts on the pigment surface to achieve "non-direct drying".

[0025] To improve the air guiding effect of the air guide plate 41, the air guide plate 41 is inclined, that is, the air guide plate 41 is inclined towards the middle of the output end of the air collecting hood 4. The inclined air guide plate 41 significantly enhances the guiding ability of hot airflow, making the originally dispersed hot air more accurately converge towards the middle, optimizing the airflow distribution in the air collecting hood 4, reducing energy loss, and achieving a more uniform heat flow output under the same energy consumption, further improving air guiding efficiency and drying uniformity. The inclination angle of the air guide plate 41 forms a guiding slope, which changes the movement trajectory of the hot air using the principle of fluid mechanics: when the hot air enters the air collecting hood 4 from the corrugated hose 3, after contacting the air guide plate 41, the airflow direction is forcibly adjusted to deflect towards the middle, and finally forms an airflow distribution of "converging in the middle and overflowing on both sides" at the output end of the air collecting hood 4, providing a more orderly initial flow field for the blocking effect of the baffle plate 42.

[0026] To improve the windproof effect of the baffle plate 42, the baffle plate 42 is arc-shaped, with its concave arc surface facing the corrugated hose 3. The arc-shaped baffle plate 42, through its special curved surface structure, gently reflects and diverts the converging hot airflow, avoiding the airflow turbulence or localized eddies that might occur with traditional flat baffle plates 42. This makes the hot air more stable and uniform when it exits through the gap between the sides of the baffle plate 42 and the output end of the air collector hood 4, further reducing the impact of the airflow on the pigment surface and improving the protective effect and drying quality. The concave arc surface of the baffle plate 42, facing the corrugated hose 3, matches the direction of the converging hot airflow: when hot air impacts the baffle plate 42, the arc-shaped surface guides the airflow to divert along both sides of the curved surface, forming a symmetrical flow effect. This allows the high-speed airflow to undergo a "deceleration-diffusion-homogenization" process before contacting the pigment, ultimately acting on the pigment with low-impact, highly uniform heat flow, balancing drying efficiency and surface protection requirements.

[0027] Example 2

[0028] Unlike Embodiment 1, to facilitate the drying of paint sprayed at different heights, a height adjustment mechanism 5 is provided on the handle 43. The height adjustment mechanism 5 includes a fixing sleeve 51 fitted onto the bottom of the handle 43 and a knurled screw 52 threaded into the top of the fixing sleeve 51 through a threaded hole, with the knurled screw 52 abutting against the outer wall of the handle 43. Through the height adjustment mechanism 5, the operator can flexibly adjust the working height of the air collection hood 4 according to the actual height of the paint spraying (such as different positions like walls or sculpture facades), without the need for additional equipment to be raised or bending over to operate, significantly improving the versatility and ease of use of the device, adapting to diverse work scenarios. The fixed sleeve 51 is fitted onto the bottom of the handle 43. The knurled screw 52 passes through the threaded hole through the top of the fixed sleeve 51 and abuts against the outer wall of the handle 43. When the knurled screw 52 is loosened, the handle 43 can slide up and down inside the fixed sleeve 51 to adjust the extension length. When the knurled screw 52 is tightened, the end of the screw presses against the outer wall of the handle 43, and the current height is fixed by friction, so as to achieve rapid stepless adjustment.

[0029] Example 3

[0030] Unlike Embodiment 1, to facilitate the fixing of the sleeve 51, both the control box 1 and the hot air blower 2 have C-shaped retainers 53 fixedly installed at their ends near the corrugated hose 3 for engaging the sleeve 51. The two C-shaped retainers 53 are arranged vertically. The C-shaped retainers 53 provide a reliable storage and fixing position for the sleeve 51, preventing the handle 43 and the air collector 4 from swinging or falling off when the device is idle. They also facilitate quick installation and disassembly during operation, improving equipment integration, saving storage space, and optimizing the operation process. The outer wall size of the sleeve 51 matches the internal width of the C-shaped retainer 53. During operation, the sleeve 51 is aligned with the opening of the C-shaped retainer 53 and inserted, using the elastic locking action of the U-shaped structure to fix the sleeve 51's position. When not in use, it can be simply pulled out. The two C-shaped retainers 53 are arranged vertically to ensure that the sleeve 51 is installed vertically and aligned with the air outlet direction of the hot air blower 2.

[0031] To ensure the stability of the fixed sleeve 51, a support plate 54 is fixedly installed on the control box 1 below the C-type bracket 53. The top of the support plate 54 has a groove 541 for the bottom of the fixed sleeve 51 to be inserted. The combined design of the support plate 54 and the groove 541 provides double stable support for the fixed sleeve 51, avoiding the shaking or sagging that may occur when it is only clamped by the C-type bracket 53, and ensuring the stability of the air collector hood 4 when stored. The bottom of the fixed sleeve 51 is inserted into the groove 541 of the support plate 54. The depth of the groove 541 is precisely matched with the bottom dimension of the sleeve, forming a mechanical limit. At the same time, the C-type bracket 53 provides horizontal clamping constraint from above, and the upper and lower parts combine to form a stable support structure.

[0032] The control method of this application is through a controller. The control circuit of the controller can be implemented by a person skilled in the art through simple programming. The power supply is also common knowledge in the art. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0033] It should be noted that many of the standard parts used in this application are available on the market, while non-standard parts can be specially customized. The connection method used in this application is also a very common method in the mechanical field, and will not be described in detail here.

[0034] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
