Abstract
Description
Technical Field
[0001] This utility model relates to the field of garment processing, specifically to a dyeing and impregnation equipment for garment fabric processing. Background Technology
[0002] Clothing fabric processing refers to the process of transforming raw textile materials into final clothing fabrics through a series of technological steps. This process includes multiple stages such as pretreatment of textile raw materials, dyeing, finishing, and garment processing. In the dyeing stage, immersion dyeing is a common dyeing process for clothing fabrics. It involves immersing the fabric in a dye solution, where the dye reacts with the fibers to give the fabric the desired color.
[0003] Traditional dyeing equipment simply places the fabric in a dyeing vat for immersion and dyeing. If the fabric is thick, immersion alone cannot guarantee that the dye can penetrate into the fabric, which will lead to uneven dyeing. In addition, during the immersion process, fabric lint and other impurities will be brought into the dyeing vat. Without filtering, the dyeing effect will be affected. Furthermore, when the dyed fabric is rolled up, it often carries a lot of dye solution, which is inconvenient to roll up without some water absorption treatment. Utility Model Content
[0004] To address the problems of traditional dyeing equipment that simply places fabric in a dyeing vat for immersion dyeing, which cannot guarantee dye penetration into the fabric, especially for thicker fabrics, resulting in uneven dyeing, and the introduction of fabric lint and other impurities into the vat during immersion without filtration, thus affecting the dyeing effect, and the inconvenience of unwinding the dyed fabric when rolling it up, where it often carries a significant amount of dye, this invention provides a dyeing device for garment fabric processing.
[0005] A dyeing and immersion equipment for garment fabric processing includes an immersion tank and a filter tank. The immersion tank has an unwinding roller and a take-up roller at both ends. Inside the immersion tank, a set of guide cylinders on the same horizontal plane guides the fabric. A water-absorbing drum is rotatably mounted on the inner wall of the immersion tank near the take-up roller. A telescopic rod is positioned corresponding to the water-absorbing drum, and a scraper is fixedly mounted at the telescopic end of the telescopic rod. The immersion tank also has a double-layer water spray pipe for spraying water onto both sides of the fabric. Inside the filter tank, a filter screen is installed, and several electric heating rods are positioned below the filter screen. The filter screen is connected to the inside of the immersion tank and the double-layer water spray pipe via water supply pipes above and below it.
[0006] Furthermore, both the dyeing box and the filter box are tanks with openings at the top. The top of the filter box is fitted with a cover that rotates via a hinge, and the cover is connected to the filter box by several bolts. Inside the filter box, there are several support blocks, and the filter screen is movably placed on the top wall of the support blocks. Several electric heating rods are fixedly installed on the bottom wall of the filter box and connected to an external power source.
[0007] Furthermore, both the unwinding roller and the winding roller include a rotating shaft and a set of vertical plates respectively fixedly installed at both ends of the dyeing tank. The rotating shaft is rotatably installed between the set of vertical plates. One end of the rotating shaft in the winding roller passes through the vertical plate and is fixedly connected to the output shaft of the servo motor installed on the outer wall of the vertical plate. The fabric can be wound around the outer wall of the rotating shaft for winding and unwinding.
[0008] Furthermore, a set of guide tubes and a water-absorbing rotating tube each include a fixed shaft fixedly installed between the inner walls of the dyeing tank, wherein a rotating tube is rotatably installed on the outer wall of the fixed shaft in the set of guide tubes, and a water-absorbing sponge is rotatably installed on the outer wall of the fixed shaft in the water-absorbing rotating tube.
[0009] Furthermore, there are three telescopic rods, which are fixedly installed on the side wall of the dyeing tank. The telescopic rod in the middle is an electric telescopic rod, and the telescopic rods on both sides are telescopic sliding rods. The side of the scraper that contacts the absorbent sponge has an arc-shaped structure, and the arc is consistent with the arc of the outer wall of the absorbent sponge.
[0010] Furthermore, the double-layer water spray pipes are fixedly installed on the side wall of the dyeing tank, and several water spray holes are respectively installed on the opposite side. Water pumps are installed on both water pipes.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: the fabric can not only be soaked in the dyeing box, but also the heated dye can be sprayed onto the front and back of the fabric through double-layer water spray pipes and spray holes, which enhances the dyeing effect inside the fabric and avoids uneven dyeing inside and outside. The dye soaked in the dyeing box can be transferred to the filter box and filtered by the filter screen to remove lint and impurities before being sprayed for dyeing. Before the dyed fabric is rolled up, most of the dye liquid can be absorbed by the water-absorbing sponge before rolling. Then, the dye liquid on the water-absorbing sponge can be scraped back into the dyeing box by the squeegee to avoid waste of dye liquid. Attached Figure Description

The following will refer to the accompanying drawings. Figures 1-4 The present invention will be described in detail with reference to the embodiments.
[0022] A dyeing and immersion equipment for garment fabric processing includes an immersion tank 1 and a filter tank 2. The immersion tank 1 is provided with an unwinding roller 3 and a winding roller 4 at both ends. The fabric can be wound around the unwinding roller 3 and the winding roller 4 to achieve the purpose of unwinding and winding. Both the immersion tank 1 and the filter tank 2 are tanks with openings at the top. The top of the filter tank 2 is provided with a top cover 13 that is rotatably provided by a hinge. The top cover 13 is connected to the filter tank 2 by several bolt structures 14 that can be opened and closed. The bolt structures 14 can be loosened to open the top cover 13, which facilitates the cleaning of the filter screen 9. After cleaning, the top cover 13 is closed to prevent the loss of internal dye temperature.
[0023] Both the unwinding roller 3 and the winding roller 4 include a rotating shaft 17 and a set of vertical plates 16 respectively fixedly disposed at both ends of the dyeing tank 1. The rotating shaft 17 is rotatably disposed between the set of vertical plates 16. One end of the rotating shaft 17 in the winding roller 4 passes through the vertical plate 16 and is fixedly connected to the output shaft of the servo motor 18 disposed on the outer wall of the vertical plate 16. The fabric can be wound around the outer wall of the rotating shaft 17 for winding and unwinding.
[0024] The fabric is pre-wound around the outer wall of the rotating shaft 17, and then arranged according to the attached... Figure 1 At the indicated positions, place the fabric around the guide cylinder 5 and the absorbent drum 6 in sequence, and pour the prepared dye into the dyeing tank 1 so that the fabric can be immersed in the dye. Start the servo motor 18, which can drive the rotating shaft 17 to rotate, thereby driving the fabric to roll up and unroll.
[0025] The dyeing box 1 is also equipped with a double-layer water spray pipe 11, which can spray water on both sides of the fabric. The filter box 2 is equipped with a filter screen 9, and several electric heating rods 10 are installed below the filter screen 9. The filter screen 9 is connected to the inside of the dyeing box 1 and the double-layer water spray pipe 11 through water supply pipes 12 above and below, respectively. Water pumps 23 are installed on both water supply pipes 12.
[0026] When the water pump 23 is started, the dye inside the dyeing tank 1 is drawn into the filter tank 2 through the water supply pipe 12. After being filtered by the filter screen 9, the lint and impurities are filtered out, and the dye liquor falls into the bottom of the filter tank below. Since several electric heating rods 10 are fixedly installed on the bottom wall of the filter tank 2 and are connected to an external power source, starting the external power source can make the electric heating rods 10 heat the dye liquor. The warm dye liquor is then transported to the double-layer spray pipe 11 through the water supply pipe 12 below.
[0027] Double-layer water spray pipes 11 are fixedly installed on the side wall of the dyeing tank 1, and several water spray holes 22 are respectively installed on the opposite side. The warm dye liquid is sprayed onto the front and back of the fabric through the water spray holes 22. A certain spray pressure and temperature can accelerate the dyeing speed of the fabric and allow the pigment to penetrate into the fabric better, avoiding uneven dyeing between the surface and the interior of the fabric.
[0028] The filter box 2 is equipped with several support blocks 15. The filter screen 9 is movably placed on the top wall of the support blocks 15, which allows the filter screen 9 to be easily and quickly removed from the filter box 2 to clean the filtered lint and impurities.
[0029] The dyeing tank 1 is also equipped with a set of guide cylinders 5 on the same horizontal plane to guide the fabric. A water-absorbing drum 6 is rotatably installed on the inner wall of the dyeing tank 1 near the take-up roller 4. The set of guide cylinders 5 and water-absorbing drum 6 each include a fixed shaft 19 fixedly installed between the inner walls of the dyeing tank 1. A drum 20 is rotatably installed on the outer wall of the fixed shaft 19 in the set of guide cylinders 5, and a water-absorbing sponge 21 is rotatably installed on the outer wall of the fixed shaft 19 in the water-absorbing drum 6.
[0030] When the fabric moves, it can drive the rotating drum 20 to rotate, which in turn guides the fabric. The fabric slides along the guide drum 5 to the absorbent sponge 21. After the fabric is tensioned by the guide drum 5 and the take-up roller 4 below, it forms a certain pressure on the absorbent sponge 21, so that the absorbent sponge 21 can absorb the water squeezed out by the pressure on the fabric, and then it is rolled up.
[0031] A telescopic rod 7 is provided corresponding to the water-absorbing drum 6. A scraper 8 is fixedly provided at the telescopic end of the telescopic rod 7. There are three telescopic rods 7, which are fixedly provided on the side wall of the dyeing tank 1. The telescopic rod 7 in the middle is an electric telescopic rod, and the telescopic rods 7 on both sides are telescopic sliding rods. The side of the scraper 8 that contacts the water-absorbing sponge 21 has an arc-shaped structure, and the arc is consistent with the arc of the outer wall of the water-absorbing sponge 21.
[0032] After the absorbent sponge 21 is fully saturated with dye solution, the telescopic rod 7 located in the middle is activated, which causes the scraper 8 to move closer to the absorbent sponge 21 under the positioning and support of the other two telescopic rods 7, scraping off the dye solution on the absorbent sponge 21 and letting it fall back into the dyeing tank 1, thus avoiding dye waste.
[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
