Description

Technical Field

[0001] This utility model relates to the field of dyeing technology, and more specifically, to a water-saving dyeing device. Background Technology

[0002] Fabric dyeing involves applying dyes to the surface of fabric or inside the fibers. Through physical or chemical processes, specifically by utilizing chromophores and auxochromes in the dye's molecular structure—groups that selectively absorb visible light—the dye exhibits a specific color. When dyes are combined with textile fibers, the dye molecules penetrate the fiber's interior or bind to the fiber through chemical bonds, thus giving the textile a durable color.

[0003] Existing dyeing equipment uses either overflow dyeing or airflow dyeing methods to dye fabrics. Overflow dyeing involves immersing the fabric in dye and continuously conveying it, while airflow dyeing involves atomizing and spraying the dye onto the fabric. Both methods achieve the purpose of continuous dyeing.

[0004] However, dyeing the fabric after wetting it will cause the dye to be carried outside the dyeing equipment. Furthermore, when the fabric is continuously conveyed, some of the dye will be splashed and dripped, resulting in a waste of dye and water resources. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a water-saving dyeing device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a water-saving dyeing device, comprising a dyeing component, a feeding component, a discharging component, and a water collection tank installed on the top of the dyeing component. A squeezing component is installed on the top of the water collection tank. The feeding component and the discharging component are respectively adapted to feed and discharge fabric. The squeezing component is adapted to squeeze and drain the discharged fabric. The water collection tank is adapted to collect the discharged water.

[0007] The dyeing assembly includes a support frame and a tank mounted on top of the support frame. Two through slots are symmetrically opened on the top of the outer side wall of the tank, and the two through slots are respectively provided corresponding to the feeding assembly and the discharging assembly.

[0008] The extrusion assembly includes two fixed plates installed on the top of the water collection tank and a connecting rod connected between the two fixed plates. Two extrusion rollers are rotatably connected between the two fixed plates. The two extrusion rollers are staggered and have a gap between them.

[0009] The present invention is further configured such that: the feeding assembly includes a feeding rack installed on the top of the tank, and the top of the feeding rack is rotatably connected to a first feeding roller and a second feeding roller, the second feeding roller being located directly above the corresponding through groove.

[0010] By adopting the above technical solution, the tank carries and collects the dye. The two channels are used to feed the fabric into the tank and take it out of the tank, respectively. When the fabric enters the tank, it comes into contact with the dye and is soaked, thereby achieving the purpose of dyeing. When the fabric is fed, it passes above the first feed roller and the second feed roller in sequence, and turns and is vertically conveyed downward at the position of the second feed roller. It then passes through the inside of the corresponding channel to reach the tank for dyeing.

[0011] The present invention is further configured such that: the discharge assembly includes a discharge rack installed on the top of the tank, the bottom of the discharge rack on the side away from the tank is installed inside the water collection tank, a second discharge roller is rotatably connected to the top of the discharge rack and above the corresponding through groove, two first discharge rollers are rotatably connected to the side of the discharge rack away from the tank, a discharge motor is installed on one side of the discharge rack, and the output end of the discharge motor is connected to one of the first discharge rollers.

[0012] By adopting the above technical solution, when the fabric is pulled out from inside the tank, the fabric first turns by passing through the second discharge roller and then passes between the two first discharge rollers. The discharge motor drives one of the first discharge rollers to rotate. Through the friction between the two first discharge rollers and the fabric, the two first discharge rollers rotate in opposite directions, and the fabric is conveyed and discharged between the two first discharge rollers. The water collection tank collects the dye and water that drips during the fabric discharge.

[0013] The present invention is further configured such that: two drive motors are installed on one side of one of the fixed plates, the output ends of the two drive motors are respectively connected to one end of the two extrusion rollers, and the outer side walls of the two extrusion rollers are provided with annular protrusions at equal intervals.

[0014] The present invention is further configured such that the two extrusion rollers are arranged at different heights, and an auxiliary roller is arranged between the two extrusion rollers.

[0015] The present invention is further configured such that: a lifting cylinder is vertically mounted downward on the side wall of one of the fixed plates, and the bottom end of the piston rod of the lifting cylinder is connected to one end of the auxiliary roller.

[0016] By adopting the above technical solution, two squeezing rollers rotate in opposite directions and drive the fabric to continue to be conveyed forward. The fabric is squeezed by the two squeezing rollers, and the dye and water inside the fabric are squeezed out and dripped into the water collection tank for collection, reducing the splashing and waste of dye and water. At the same time, the lifting cylinder drives the corresponding auxiliary roller to move between the two squeezing rollers, which not only squeezes the fabric, but also reduces the gap between the two squeezing rollers. In addition, while the two squeezing rollers squeeze the fabric once, the auxiliary roller and the two squeezing rollers each increase the number of squeezes, further improving the water squeezing effect of the fabric.

[0017] In summary, this application includes at least one of the following beneficial technical effects:

[0018] By setting two squeezing rollers, the two squeezing rollers rotate in opposite directions and drive the fabric to continue to be conveyed forward. During the conveying process, the fabric is squeezed by the two squeezing rollers, and the dye and water inside the fabric are squeezed out and dripped into the water collection tank for collection, reducing the splashing and waste of dye and water.

[0019] When the fabric is squeezed by two squeezing rollers, the lifting cylinder drives the corresponding auxiliary roller to move between the two squeezing rollers. This not only squeezes the fabric but also reduces the gap between the two squeezing rollers. In addition, while the two squeezing rollers squeeze the fabric once, the auxiliary roller and the two squeezing rollers each squeeze once more, further improving the squeezing effect of the fabric.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0031] Please see Figures 1-4 The present invention provides the following technical solution:

[0032] Example 1, see Figure 1 and Figure 2 A water-saving dyeing device includes a dyeing component 1, which is used to dye fabric. The dyeing component 1 includes a support 11 and a tank 12 installed on the top of the support 11. Two through slots 13 are symmetrically opened on the top of the outer side wall of the tank 12. The tank 12 is used to carry and collect dye. The two through slots 13 are used to feed the fabric into the tank 12 and to take it out of the tank 12, respectively. When the fabric enters the tank 12, it comes into contact with the dye and is soaked, thereby achieving the purpose of dyeing.

[0033] See Figure 1 The top of the tank body 12 is equipped with a feeding assembly 2 and a discharging assembly 3. Two through slots 13 are respectively provided corresponding to the feeding assembly 2 and the discharging assembly 3. The feeding assembly 2 and the discharging assembly 3 are respectively used for feeding and discharging the fabric. The specific structure of the feeding assembly 2 is as follows:

[0034] See Figure 1 and Figure 2 The feeding assembly 2 includes a feeding rack 21 installed on the top of the tank 12. The top of the feeding rack 21 is rotatably connected to a first feeding roller 22 and a second feeding roller 23. The second feeding roller 23 is located directly above the corresponding through groove 13. When the fabric is fed, it passes above the first feeding roller 22 and the second feeding roller 23 in sequence. At the position of the second feeding roller 23, it turns and is conveyed vertically downwards, passing through the inside of the corresponding through groove 13 to reach the tank 12 for dyeing.

[0035] See Figure 2 A water collection trough 5 is installed on the top of the support 11 and on one side of the tank body 12. The water collection trough 5 is located below the discharge assembly 3. The specific structure of the discharge assembly 3 is as follows:

[0036] See Figure 1 and Figure 2 The discharge assembly 3 includes a discharge rack 31 installed on the top of the tank 12. The bottom of the discharge rack 31, away from the tank 12, is installed inside the water collection tank 5. A second discharge roller 33 is rotatably connected to the top of the discharge rack 31 and above the corresponding through groove 13. Two first discharge rollers 32 are rotatably connected to the side of the discharge rack 31 away from the tank 12. A discharge motor 34 is installed on one side of the discharge rack 31. The output end of the discharge motor 34 is connected to one of the first discharge rollers 32. When the fabric is pulled out from inside the tank 12, the fabric first passes through the second discharge roller 33 to turn and then passes between the two first discharge rollers 32. The discharge motor 34 is used to drive one of the first discharge rollers 32 to rotate. Through the friction between the two first discharge rollers 32 and the fabric, the two first discharge rollers 32 rotate towards each other, and the fabric is discharged between the two first discharge rollers 32. The water collection tank 5 is used to collect the dye and water that drips during the fabric discharge.

[0037] See Figure 1 The top of the water collection tank 5 is equipped with a squeezing assembly 4. The squeezing assembly 4 is used to squeeze and drain the fabric during feeding to reduce the waste of dye and water splashing. The specific structure of the squeezing assembly 4 is as follows:

[0038] See Figure 3 and Figure 4 The extrusion assembly 4 includes two fixed plates 41 installed on the top of the water collection tank 5 and a connecting rod 42 connected between the two fixed plates 41. The two fixed plates 41 and the connecting rod 42 cooperate to form the main structure of the extrusion assembly 4. Two extrusion rollers 43 are rotatably connected between the two fixed plates 41. Two drive motors 44 are installed on one side of one of the fixed plates 41. The output ends of the two drive motors 44 are respectively connected to one end of the two extrusion rollers 43. The two extrusion rollers 43 are staggered and there is a gap between them. When the fabric passes through the two first discharge rollers 32 and enters between the two extrusion rollers 43, the two drive motors 44 drive the corresponding extrusion rollers 43 to rotate respectively, and the rotation directions of the two drive motors 44 are opposite, causing the two extrusion rollers 43 to rotate towards each other and drive the fabric to continue to be conveyed forward. During the conveying process, the fabric is squeezed by the two extrusion rollers 43, and the dye and water inside the fabric are squeezed out and dripped into the water collection tank 5 for collection.

[0039] See Figure 3 and Figure 4 Both extrusion rollers 43 have annular protrusions at equal intervals on their outer side walls. By setting the annular protrusions, the contact area between the extrusion rollers 43 and the fabric is increased, thereby improving the water squeezing effect.

[0040] See Figure 3 and Figure 4An auxiliary roller 45 is positioned between the two squeezing rollers 43. A lifting cylinder 46 is vertically mounted downwards on the side wall of one of the fixed plates 41. The bottom end of the piston rod of the lifting cylinder 46 is connected to one end of the auxiliary roller 45. When the fabric is squeezed by the two squeezing rollers 43, the lifting cylinder 46 drives the corresponding auxiliary roller 45 to move between the two squeezing rollers 43. This not only squeezes the fabric but also reduces the gap between the two squeezing rollers 43. In addition, while the two squeezing rollers 43 squeeze the fabric once, the auxiliary roller 45 and the two squeezing rollers 43 each increase the number of squeezes, further improving the squeezing effect of the fabric.
