Description

Technical Field

[0001] This invention relates to the field of electrostatic spraying technology for denim fabrics, specifically to an electrostatic spraying and dyeing equipment for denim fabrics. Background Technology

[0002] The core of denim fabric is denim, also known as twill cotton. It is made primarily of cotton and is produced using a twill weave with coarse warp yarns and fine weft yarns. It is often dyed with indigo to present a classic blue tone. It is thick, durable, and wrinkle-resistant. Some styles will add a small amount of spandex and polyester fibers to optimize elasticity and drape. The surface characteristics of dyed warp yarns and undyed weft yarns make the fabric easy to form a unique distressed and whiskered effect after wearing, which retains the practicality of workwear fabrics while also being fashionable and versatile.

[0003] In denim production, to achieve the desired color presentation and style shaping of the fabric, and to meet both practical and fashionable needs, basic dyeing and printing equipment is responsible for dyeing cotton fabrics into classic indigo shades. At the same time, the dyeing process gives the fabric the plasticity for subsequent distressing. Electrostatic spraying dyeing equipment is an upgraded option for special effects. It can precisely control dye adhesion, achieving localized spraying, gradients, and delicate textures resembling frosted finishes. This not only improves dyeing efficiency and reduces dye waste, but also creates personalized visual effects, allowing denim to break free from the limitations of single colors, adapt to more diverse design styles, and satisfy consumers' pursuit of fashion.

[0004] However, the existing electrostatic spraying and dyeing equipment for denim fabric has the following shortcomings:

[0005] Currently, in the actual electrostatic spraying and dyeing process for jeans on the market, the process involves first manually placing the jeans onto an inflatable leg mold for fixation, and then using a spray nozzle to spray and dye them. Utilizing the properties of electrostatics, the dye can be effectively adsorbed onto the fabric. Through natural sedimentation and absorption by the fabric, the dye combines with the material. However, in the production of high-end jeans, due to differences in the materials and textures of the denim fabrics, the sprayed dye tends to float only on the shallow surface of the fabric during actual spraying. This results in the jeans fading more quickly during later wear, affecting their usability.

[0006] Therefore, this invention proposes an electrostatic spraying and dyeing equipment for denim fabric to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide an electrostatic spraying and dyeing equipment for denim fabric. During spraying, the denim fabric is first placed on an inflatable leg mold and inflated for fixation. A linear motor is started to drive a moving frame, simultaneously inflating the air ring through an air blower. Due to its larger dimensions, the thigh area receives increased air volume, flattening the corresponding fabric and straightening the fibers, increasing the paint contact area, and helping large paint particles penetrate the nap layer, improving absorption efficiency and spraying quality. During spraying, the suction rubber ring on the outside of the air ring fits against the leg mold, and the suction machine drives airflow from the outside of the fabric inwards, enhancing spray penetration and carrying unabsorbed paint particles into the deeper layers of the fabric, solving the penetration problem caused by electrostatic adsorption, improving paint adhesion, and reducing color fading in denim. The equipment also uses a second motor to drive a rotating support arm, and a lifting device drives the spray gun up and down.

[0014] Preferably, a spray gun is mounted on the other end of the robotic arm, and a spray head is mounted on the middle output end of the spray gun.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention involves first placing the jeans on an inflatable leg mold and inflating it to secure it during the spraying process on denim fabric. A linear motor is then activated to move a moving frame, while air is simultaneously inflated into an air ring on the moving frame via an air blower. The air volume of the air ring is adjusted according to the location of the jeans. When the air ring is at the thigh, due to its larger dimensions, increasing the air volume allows the air ring to appropriately expand the corresponding area. After the fabric is stretched, the surface becomes smoother, the fibers straighten, and the spacing between fibers and cotton fibers increases. This expands the contact area of ​​the coating, improves the uniformity of fusion, and allows larger coating particles to better penetrate the fibers. The fleece layer contacts the deep layers of the fabric, accelerating paint absorption and improving spraying quality. During spraying, the suction rubber ring on the outside of the air ring fits tightly against the leg mold. After the suction machine is started, the airflow flows from the outside of the fabric to the inside, enhancing the penetration of the spray particles. It can also carry unabsorbed paint particles and inter-fiber spray into the deep layers of the fabric, solving the problem of low penetration efficiency caused by electrostatic adsorption. This further improves the adhesion of the paint and avoids the situation where the sprayed dye only floats on the shallow surface of the fabric, thus preventing the jeans from fading too quickly and affecting their normal use.

[0021] 2. To improve the spraying effect, the device of this invention starts a second motor to drive the rotating support arm to rotate a wide range within the spraying chamber, and the lifting device drives the spray gun to move up and down. The robotic arm further expands the spraying range and adjusts the spraying angle, while improving the autonomous spraying effect. The main spraying head and the auxiliary spraying head combine to form a multi-angle spray arc, which better adapts to the ring-shaped fabric supported by the air ring, increases the angle matching degree between the spray and the fabric and the original contact fusion angle, reduces the difficulty of adjusting the spray in the later stage, and ensures the stability of the spraying effect.

One limiting arc block 217 is installed on the outer side of the moving frame 210. A tension spring 218 is installed on the inner side of the adjacent limiting arc blocks 217.

The top of the air suction pipe 211 is connected to an air suction machine 219.

[0034] The overall effect of Embodiment 1 is as follows: When spraying the denim fabric, the denim to be sprayed is first placed on the inflatable leg mold 205, then the inflatable leg mold 205 is inflated to support and fix the denim. Then, the linear motor device 206 is activated to move the moving frame 210 up and down. Simultaneously, the air ring 213 is inflated through the air pipe 212. The amount of air in the air ring 213 depends on the location of the denim. When the air ring 213 is positioned at the thigh area, because the thigh is relatively large, the amount of air in the air ring 213 is increased, allowing the air ring 213 to be inflated properly. Inside mold 205, the inflatable leg mold 205 and the thigh area of ​​the jeans are stretched within a reasonable range. This stretches the jeans fabric, making the uneven surfaces relatively flat, and the fibers within the fabric straighten, increasing the gaps between them. At this point, when spraying this area, the surface area that the paint spray can contact is relatively larger, increasing the uniformity of the coating. Simultaneously, as the fabric is stretched and the area increases, the distance between the cotton fibers on the fabric surface also increases, allowing larger paint particles to penetrate the fiber layer better and thus make contact with the deeper layers of the fabric. The mist particles reduce the obstruction of fuzz and lower surface tension on the deep surface of the fabric, allowing them to disperse better and further enhance contact with the fabric. This ultimately improves the degree and speed of the fabric's absorption of the coating, thereby improving the spraying quality. During spraying, because the suction rubber ring 214 is located at the outermost and most convex point of the air ring 213, and the suction rubber ring 214 fits tightly with the inflatable leg mold 205, the suction machine 219 is activated. Through the suction pipe 211 and the suction head 215, the suction rubber ring 214 draws air through the inflatable leg mold 205 into the denim fabric outside the inflatable leg mold 205, thus improving the denim... Airflow from the outer surface of the trouser fabric moves inwards, increasing the impact of the sprayed particles on the fabric's surface nap. The core of this device utilizes electrostatic adsorption; some paint particles, due to electrostatic adsorption, cannot penetrate deeper into the fabric. By increasing this airflow, paint particles already adsorbed on the fabric fiber surface but not yet absorbed are drawn and rotated into the deeper fiber layers. Furthermore, some sprayed particles located between the fibers are drawn into the deeper layers, further increasing the integration of the fabric and the paint spray, allowing the paint to penetrate deeper into the fabric and enhancing its adhesion.

[0035] Example 2, according to Figure 7 - Figure 9As shown, the spraying mechanism 3 includes a spraying chamber 301, which is located on the outside of the base 1. A second motor 302 is mounted on the top of the spraying chamber 301. A rotating support arm 303 is mounted on the bottom output end of the second motor 302. A lifting device 304 is mounted on the other end of the rotating support arm 303. A robotic arm 305 is mounted on the bottom of the lifting device 304. A spray gun 306 is mounted on the other end of the robotic arm 305. A main spraying head 307 is mounted on the middle output end of the spray gun 306. Two auxiliary spraying heads 308 are mounted on the outer output ends of the spray gun 306. The outer sides of the main spraying head 307 and the auxiliary spraying heads 308 are all connected. There is a paint tube 309, and the other end of the paint tube 309 is connected to an adapter 311. The adapter 311 is installed on the outside of the spray booth 301. A paint pressure bottle 310 is installed on the top of the adapter 311. A high-pressure air pipe 313 is connected to the outside of the spray gun 306. The other end of the high-pressure air pipe 313 is connected to an air pump device 312. A third motor 4 is installed on the inside of the base 1. The output end of the third motor 4 passes through the base 1 and is equipped with a partition 5. A rotating frame 6 is installed on the top of the partition 5. The material of the inflatable leg mold 205 is microporous PVC film composite cloth. The materials of the suction rubber ring 214 and the air ring 213 are both elastic rubber.

[0036] The overall effect of Embodiment 2 is as follows: To further improve the spraying effect, the second motor 302 is started to drive the rotating support arm 303 to rotate within the spraying chamber 301. The lifting device 304 drives the spray gun 306 to move up and down. The robotic arm 305 expands the spraying range of the spray gun 306, adjusts the spraying angle, and improves the autonomous spraying effect. The main spraying head 307 and the auxiliary spraying head 308 are combined to form a multi-angle spray arc, which is adapted to the annular fabric supported by the air ring 213, increasing the angle matching degree between the spray and the fabric and the original contact fusion angle, reducing the difficulty of adjusting the spray later. Among them, the partition 5 avoids the paint from contaminating the outside world and other jeans when spraying each denim fabric. The third motor 4 drives the rotating frame 6 to rotate, which ensures the continuity of spraying multiple denim fabrics and improves the spraying efficiency.

[0037] The working principle of the entire equipment is as follows: When spraying jeans, the jeans are first placed on the inflatable leg mold 205, and the inflatable leg mold 205 is inflated to support and fix the jeans. The linear motor device 206 is started to drive the moving frame 210 to move up and down. At the same time, the air ring 213 is inflated through the air pipe 212. The inflation amount of the air ring 213 is adjusted according to the part of the jeans. When the air ring 213 moves to the thigh area, the air volume of the air ring 213 is increased because the thigh is larger. Within a reasonable range, the inflatable leg mold 205 and the thigh area of ​​the jeans are expanded, and the jeans surface... After the material is stretched out, the uneven surface becomes flat, the fibers within the fabric straighten, and the gaps between the fibers increase. At this point, spraying this area increases the surface area of ​​the fabric that the paint spray contacts, improving the uniformity of the coating. Simultaneously, the increased spacing between the cotton fibers on the fabric surface allows larger paint particles to better penetrate the fiber layer and contact the deeper layers of the fabric. Furthermore, the reduced resistance from the fibers at the deeper layers lowers tension, allowing the spray particles to disperse more effectively, further enhancing the contact effect with the fabric. This accelerates the absorption of the paint and improves its completeness, thereby improving the overall spraying performance. During the spraying process, the suction rubber ring 214 is located at the outermost and most convex part of the air ring 213, closely fitting the inflatable leg mold 205. When the suction machine 219 is activated, air is drawn through the suction pipe 211 and suction head 215 from the outer denim fabric via the suction rubber ring 214 and the inflatable leg mold 205. This causes the airflow on the outer surface of the denim to flow inwards. This airflow increases the impact force of the sprayed particles on the nap resistance of the fabric's outer surface. Because the core of the device uses electrostatic adsorption, some paint particles cannot penetrate deep into the fabric due to electrostatic adsorption, while the airflow can carry... The paint particles that have been adsorbed onto the surface of the fabric fibers but have not been absorbed rotate to the deeper layers of the fibers. At the same time, some spray particles located between the fibers are sucked into the deeper layers between the fibers, further increasing the fusion between the fabric and the paint spray, allowing the paint to penetrate into the deeper layers of the fabric and improving the adhesion of the paint. The hub 220 automatically retracts and extends the air pipe 212, ensuring that the moving frame 210 can maintain the connection between the air pipe 212 and the air ring 213 when moving up and down. The first motor 201 drives the inflatable leg mold 205 to rotate, increasing the spraying angle and improving the spraying effect.

[0038] To further improve the spraying effect, the second motor 302 is activated to drive the rotating support arm 303 to rotate within the spraying chamber 301. The lifting device 304 drives the spray gun 306 to move up and down. The robotic arm 305 increases the autonomous spraying effect, spraying range, and angle of the spray gun 306. Finally, the main spray head 307 and the auxiliary spray head 308 combine to form multiple spray arcs at different angles to match the annular fabric supported by the air ring 213. This increases the matching degree between the spray spray and the fabric angle and the original contact fusion angle, thereby reducing the difficulty of adjusting the spray in the later stages.
