Description

Technical Field

[0001] This utility model relates to the technical field of plant dye processing equipment, and in particular to an integrated spraying and drying equipment for light fastness finishing of plant dyes. Background Technology

[0002] With increasing global awareness of sustainable development and environmental protection, natural plant dyes have regained widespread attention in the field of textile dyeing and finishing due to their unique advantages such as being renewable, biodegradable, and friendly to humans and the environment. However, compared with synthetic dyes, most plant dyes face a key technical bottleneck: they are prone to fading or discoloration under light, and their light fastness is generally poor. This severely restricts the commercial application of plant dyes in high-quality textiles. To improve their light fastness, specialized finishing processes are usually required, such as treating the dyed fabrics with natural or environmentally friendly light stabilizers.

[0003] Currently, the conventional process for light fastness finishing of plant-dyed fabrics mostly adopts the padding method, which involves immersing the fabric in a working solution containing finishing agents, then uniformly pressing it through rollers before drying it in a drying oven. This intermittent processing method has obvious drawbacks: the production process is long, inefficient, the dye distribution is not uniform, and it is easy to cause color fading.

[0004] Therefore, it is necessary to provide an integrated spraying and drying equipment for light fastness treatment of plant dyes to solve the above-mentioned technical problems. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the existing technology, this utility model provides an integrated spraying and drying equipment for light fastness finishing of plant dyes.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An integrated spraying and drying equipment for light fastness finishing of plant dyes includes: a box body, a feeding roller at the top of the box body, a set of spraying pipes inside the box body, a feeding pipe between one end of the spraying pipes, a smoothing component inside the box body near the bottom of the spraying pipes, one end of the smoothing component extending through the outside of the box body, a gear on one end of the smoothing component, an upper rack above the gear at one end, a lower rack below the gear at the other end, chains on the inner sides of both the upper and lower racks, a sprocket between the chains, a telescopic rod on one side of the upper rack, a heating box above one side of the box body, a guide roller at the bottom of the box body, and a set of discharge rollers on one side of the box body.

[0007] Preferably, the smoothing component has a brush bar inside, and a plurality of springs are provided between the smoothing component and the brush bar.

[0008] Preferably, a slider is provided between one side of the upper and lower racks and the housing, and a groove is provided on the outer side of the slider.

[0009] Preferably, the heating box has multiple heating tubes inside, several air vents at the bottom, and a fan at the top.

[0010] Preferably, an air guide pipe is provided between the top of the box and the heating box, and a set of air outlet pipes is provided inside the box near the lower part of the air vent. A connecting pipe is provided on the rear side of the box, the bottom of the connecting pipe is connected to the air outlet pipe, and an air pump is provided on the connecting pipe.

[0011] Compared with the prior art, the present invention has the following beneficial effects: (1) This utility model drives the meshing transmission of the upper and lower racks and gears through the telescopic rod, and uses the chain and sprocket to achieve linkage, driving the smoothing component to swing back and forth. At the same time, the elastic brush strip set inside the component can adapt to the thickness of different fabrics, realize the dynamic smoothing and brushing of the dye sprayed on the fabric surface, effectively avoid the problem of droplet accumulation and uneven distribution that is easy to be generated by traditional static spraying, improve the uniformity of plant dye on the fabric surface, and effectively improve the processing efficiency of the device. (2) This utility model provides stable hot air through a heating box and a fan, and uses a dual-path air supply. The hot air is blown from the bottom air vent of the heating box to the top of the fabric, and part of the hot air is guided to the air outlet at the bottom of the box through an air pump and connecting pipe to dry the bottom of the fabric. Combined with the air guide pipe at the top of the box, the residual heat is recovered and circulated, ensuring that the fabric is heated evenly on both sides, greatly improving the drying efficiency and quality, and effectively avoiding the problems of discoloration of plant dyes or poor curing of finishing agents caused by local overheating or insufficient drying.

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments. The embodiments of the present invention include, but are not limited to, the following embodiments.

[0015] Example 1 like Figure 1-5As shown, the integrated spraying and drying equipment for light fastness finishing of plant dyes provided by this utility model includes: a housing 1, with a feeding roller 2 disposed on the top of the housing 1, and a feeding port on the side of the top of the housing 1 near the feeding roller 2, facilitating the feeding of fabric into the housing 1 through the feeding port using the feeding roller 2 for the spraying and drying process; a set of spraying pipes 8 disposed inside the housing 1, with a feeding pipe 9 disposed between one end of each spraying pipe 8, and a feed pump installed on the feeding pipe 9; during use, external spraying dye is fed into the interior of the spraying pipes 8 through the feeding pipe 9, and then sprayed... The coating is sprayed from pipe 8 to both sides of the fabric. A smoothing component 21 is located inside the housing 1, near the lower part of the spray pipe 8. After spraying, the smoothing component 21 can be used to smooth the sprayed dye on the fabric surface, ensuring the dye adheres evenly to the fabric, improving the uniformity of the coating, and guaranteeing the quality of the fabric. One end of the smoothing component 21 extends through the outside of the housing 1, and a gear 16 is provided on one end of the smoothing component 21. The other end is rotatably connected to the housing 1. An upper rack 14 is provided above the gear 16 at one end, and a... The device includes a lower rack 15, a gear 16, and upper and lower racks 14 and 15 that mesh with each other. Chains 17 are installed on the inner sides of both the upper and lower racks 14 and 15, with sprockets 20 positioned between the chains 17. A telescopic rod 13 is installed on one side of the upper rack 14. The telescopic rod 13 can be an electric push rod, a pneumatic cylinder, or a hydraulic cylinder, depending on the requirements. In use, the telescopic rod 13 is activated, pushing the upper rack 14 to move left and right. Under the action of the chain 17 at the bottom of the lower gear 14, the sprocket 18 rotates, simultaneously causing the lower rack 15 to move left and right, thus achieving meshing. The simultaneous rotation of wheel 16 drives the smoothing component 21 to rotate, smoothing the fabric as it moves up and down, making the coating more uniform and ensuring the quality of the fabric spraying. A heating box 4 is provided on the upper side of one side of the box 1 to facilitate subsequent drying of the sprayed fabric and remove moisture from the fabric. A guide roller 3 is provided at the bottom of the inside of the box 1, and a set of discharge rollers 5 is provided on one side of the box 1 to guide the fabric inside the box 1, realizing the process of spraying the fabric first and then drying it. After processing, the fabric is discharged along the discharge rollers 5 for the next processing and finishing step.

[0016] Example 2 like Figure 4 As shown, the smoothing component 21 is equipped with a brush strip 23 inside, and several springs 22 are arranged between the smoothing component 21 and the brush strip 23. When smoothing the fabric evenly, the brush strip 23 can be used to spray the coating evenly on the fabric surface. In addition, with the use of the springs 22, the length of the brush strip 23 can be adjusted when the smoothing component 21 is swung, ensuring the applicability of the brush strip 23 and adapting to fabrics of different thicknesses, thus further improving the practicality of the device.

[0017] Example 3 like Figure 1 and Figure 3 As shown, a slider 19 is provided between one side of the upper rack 14 and the lower rack 15 and the housing 1. A groove 18 is provided on the outer side of the slider 19, so that the upper rack 14 and the lower rack 15 can simultaneously drive the slider 19 to move within the groove 18 during the movement of the upper rack 14 and the lower rack 15, ensuring the stability of the movement of the upper rack 14 and the lower rack 15 and avoiding shaking.

[0018] Example 4 like Figure 4 As shown, the heating box 4 is equipped with multiple heating tubes 24 inside, and several air vents 25 are provided at the bottom of the heating box 4. A fan 6 is provided above the heating box 4. When drying the fabric, the fan 6 can be started to introduce external gas into the heating box 4. The gas is heated by the heating tubes 24 and then blown out from the air vents 25 to achieve heating and drying of the fabric.

[0019] Example 5 like Figure 3-4 As shown, an air guide pipe 7 is provided between the top of the box body 1 and the heating box 4. During the drying process, excess hot air can automatically drift upwards and enter the interior of the heating box 4 through the air guide pipe 7 for reheating, thus achieving hot air circulation. A set of air outlet pipes 12 is provided inside the box body 1 near the air vent 25. A connecting pipe 10 is provided on the rear side of the box body 1. The bottom of the connecting pipe 10 is connected to the air outlet pipe 12. An air pump 11 is provided on the connecting pipe 10. During heating and drying, the air pump 11 can be started to guide some of the hot air from the connecting pipe 10 into the interior of the air outlet pipe 12 and then spray it out to heat the bottom of the fabric, ensuring the overall drying of the fabric, preventing drying dead corners, and improving the processing quality of plant dyes on the fabric.

[0020] The working principle of the integrated spraying and drying equipment for light fastness finishing of plant dyes provided by this utility model is as follows: In use, the fabric is fed into the inlet above the side of the housing 1 via the feed roller 2. First, it passes through a set of spray pipes 8, where the plant-based dye finishing agent, delivered by the feed pipe 9, is evenly sprayed onto the upper and lower surfaces of the fabric. Then, the fabric enters the finishing zone formed by the smoothing component 21. At this time, the telescopic rod 13 is activated, pushing the upper rack 14 to move. Through the coordinated movement of the gear 16 meshing with it and the lower rack 15 driven by the chain 17 and sprocket 20, the smoothing component 21 is driven to oscillate back and forth. The brush strips 23 inside, elastically supported by the spring 22, adapt to the fabric thickness, smoothing and evenly brushing the surface finishing agent to ensure uniform coverage without accumulation. After the coating process is completed, the fabric enters the drying section under the guidance of the guide roller 3. The fan 6 is started to send air into the heating box 4. After being heated by multiple heating tubes 24 inside, hot air is generated and blown from the bottom air outlet 25 onto the upper surface of the fabric. At the same time, the air pump 11 diverts part of the hot air to the air outlet 12 at the bottom of the box through the connecting pipe 10 to heat the lower surface of the fabric, so as to achieve uniform drying on both sides. The residual heat generated during the drying process is returned to the heating box 4 through the air guide pipe 7 above the box 1 to realize the heat energy recycling. Finally, the completely dried fabric is led out of the equipment by the discharge roller 5, completing the integrated coating and drying process of the entire light fastness finishing.

[0021] The above embodiments are merely one of the preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any modifications or refinements made to the main design concept and spirit of this utility model that are not of substantial significance, but solve the same technical problem as this utility model, should be included within the scope of protection of this utility model.
