Description

Technical Field

[0001] This utility model relates to the technical field of silk double-layer four-way stretch fabric, specifically a jet dyeing machine for processing silk double-layer four-way stretch fabric. Background Technology

[0002] Double-layer four-way stretch silk fabric is a composite fabric that combines natural fibers with elasticity. It has good breathability and a comfortable feel against the skin. At the same time, due to the addition of double-layer structure and four-way elastic design, it has good elastic recovery performance and extensibility while maintaining the traditional silk texture. It is widely used in high-end clothing, functional underwear, and close-fitting sportswear.

[0003] Currently, the main dyeing method used for this type of fabric is immersion dyeing. However, due to the complex structure of double-layer four-way stretch silk fabric, such as double-layer interweaving and four-way stretching, simple immersion cannot allow the dye to fully penetrate the fabric layers, easily causing problems such as large color difference between the front and back sides and low color fastness. The fabric also has poor absorption efficiency of the dye. Therefore, there is an urgent need for a jet-type dyeing machine for processing double-layer four-way stretch silk fabric to solve the above-mentioned technical defects. Utility Model Content

[0004] The purpose of this invention is to provide a jet-type dyeing machine for processing double-layer four-way stretch silk fabric, in order to solve the problem mentioned in the background art that simply relying on soaking cannot allow the dye liquor to fully penetrate the fabric interlayer, resulting in poor absorption efficiency of the fabric by the dye liquor.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a jet-type dyeing machine for processing double-layer four-way stretch silk fabric, comprising a base and a dyeing chamber. The dyeing chamber is located at the top of the base, and a constant-temperature dye liquor tank is located on the left side of the dyeing chamber. A dye pump is installed at the top of the constant-temperature dye liquor tank. A distributor is installed on the output pipe of the dye pump, which splits the flow into two pipes and connects them to a spray frame respectively. The spray frame is located inside the dyeing chamber, and multiple sets of equally spaced nozzles are arranged inside the spray frame. The nozzles are aimed at the front and back of the fabric.

[0006] As a further technical solution of this utility model, the spray frame is inclined and the bottom of the dyeing chamber is provided with a dyeing roller, and the fabric forms a "V" shaped dyeing path through the dyeing roller.

[0007] As a further technical solution of this utility model, a fixed guide roller group is installed on the left side of the top of the dyeing chamber. The fixed guide roller group consists of two sets of rotatable rollers with a width adapted to the fabric.

[0008] As a further technical solution of this utility model, a squeezing chamber is provided on the right side of the top of the dyeing chamber. Two sets of movable guide rollers are installed in the squeezing chamber. A squeezing assembly is provided on the left side of the squeezing chamber. A servo motor is fixedly connected to the top of the squeezing assembly. A threaded rod is fixedly connected to the output shaft of the servo motor. A set of threaded blocks is sleeved on each of the outer sides of the threaded rod. A roller frame is fixedly connected to the right side of the threaded blocks. The roller frame is movably connected to the movable guide rollers.

[0009] As a further technical solution of this utility model, the movable guide roller group and the fixed guide roller group are symmetrically distributed, the bottom end of the extrusion chamber is provided with a channel communicating with the dyeing chamber, and the right side of the extrusion chamber is provided with a channel for the fabric to be discharged.

[0010] As a further technical solution of this utility model, a storage box is provided on the top right side of the staining chamber, and a reflux trough is provided below the storage box. The storage box and the reflux trough are connected by a pipeline, and the storage box and the staining chamber are connected by a reflux pump.

[0011] As a further technical solution of this utility model, a level gauge is installed on the right side of the reflux tank for monitoring the water level.

[0012] As a further technical solution of this utility model, a conveying roller is provided on the left side of the constant temperature dyeing tank, and the conveying roller corresponds to the fixed guide cloth roller group in the front and rear positions.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the jet dyeing machine for processing double-layer four-way elastic silk fabric not only realizes the dye penetration of elastic fibers, ensuring dyeing rate and uniformity, and does not damage the elastic structure of the fabric, but also realizes dye recovery.

[0014] (1) By setting up a dyeing chamber, dyeing roller, spray frame, nozzle, dye pump, constant temperature dye liquor tank, base, and distributor, multiple sets of nozzles are set at equal intervals in the spray frame and the nozzles are respectively aimed at the front and back of the silk double-layer four-way elastic fabric. The dye liquor, which is heated at a constant temperature in the constant temperature dye liquor tank, is diverted into two spray frames by the distributor. Then the nozzles spray the fabric evenly on both sides. The fabric moves along a "V" shaped path in the dyeing chamber. Along the way, the dyeing roller supports the dyeing and forms a dye liquor surrounding and covering, thereby improving the fabric's absorption efficiency of the dye liquor. It can better stimulate the dye penetration of elastic fibers than the traditional soaking method. The dye liquor reaches the inside of the double-layer structure of the fabric under high pressure, while ensuring the dyeing rate and uniformity. It solves the problem of uneven dyeing and obvious color difference of common dyeing machines on silk elastic fabrics.

[0015] (2) By setting up an extrusion assembly, an extrusion chamber, a movable guide roller group, a servo motor, a threaded block, and a threaded rod, the movable guide roller group can be adjusted symmetrically. When the fabric passes between the movable guide roller groups, it is clamped and extruded to complete the recycling of residual liquid from the dyed fabric. This structure adjusts the extrusion intensity by controlling the speed and direction of the servo motor, without damaging the elastic structure of the fabric.

[0016] (3) By setting up a storage tank, a return tank, and a level gauge, excess dye liquor generated after the fabric is squeezed, as well as dye liquor soaked in the dyeing room, are collected in the storage tank. After being temporarily stored in the storage tank, the dye liquor is guided to the return tank through a pipeline for centralized recycling. A level gauge is set on the right side of the return tank to monitor the liquid level. When the liquid level exceeds the preset value, the system can control the dye liquor to stop recycling or pump it back into the constant temperature dye liquor tank for recycling. By combining recycling with liquid level sensing, the problems of insufficient recycling and untimely control of existing equipment are solved. Attached Figure Description

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

[0023] Please see Figure 1-4An embodiment of this utility model provides a jet-type dyeing machine for processing double-layer four-way stretch silk fabric, including a base 15 and a dyeing chamber 9. The dyeing chamber 9 is set at the top of the base 15. A constant temperature dye liquor tank 14 is located on the left side of the dyeing chamber 9. A dye pump 13 is installed at the top of the constant temperature dye liquor tank 14. A distributor 16 is installed on the output pipe of the dye pump 13. The distributor 16 splits the flow into two pipes and connects them to the spray frame 11 respectively. The spray frame 11 is located inside the dyeing chamber 9. Multiple sets of equally spaced nozzles 12 are arranged inside the spray frame 11. The nozzles 12 are aimed at the front and back of the fabric. The spray frame 11 is inclined. A dyeing roller 10 is set at the bottom of the dyeing chamber 9. The fabric forms a "V"-shaped dyeing path after passing through the dyeing roller 10.

[0024] Specifically, such as Figure 1 and Figure 2 As shown, by arranging multiple sets of nozzles 12 at equal intervals within the spray frame 11 and positioning the nozzles 12 against the front and back sides of the double-layer four-way stretch silk fabric, the dye liquor, heated at a constant temperature in the constant temperature dye liquor tank 14, is diverted by the distributor 16 into the two spray frames 11. The nozzles 12 then uniformly spray the fabric onto both sides. The fabric travels along a "V" shaped path inside the dyeing chamber 9, and is supported by the dyeing rollers 10 to form a dye liquor-enclosed coverage, thereby improving the fabric's absorption efficiency of the dye liquor.

[0025] A fixed guide roller group 2 is installed on the top left of the dyeing chamber 9. The fixed guide roller group 2 consists of two sets of rotatable rollers with a width adapted to the fabric. A squeezing chamber 4 is set on the top right of the dyeing chamber 9. Two sets of movable guide roller groups 5 are installed in the squeezing chamber 4. A squeezing assembly 3 is set on the left side of the squeezing chamber 4. A servo motor 17 is fixedly connected to the top of the squeezing assembly 3. A threaded rod 19 is fixedly connected to the output shaft of the servo motor 17. A set of threaded blocks 18 are sleeved on each side of the threaded rod 19. A roller frame 20 is fixedly connected to the right side of the threaded blocks 18. The roller frame 20 is movably connected to the movable guide roller group 5. The movable guide roller group 5 and the fixed guide roller group 2 are symmetrically distributed. A channel communicating with the dyeing chamber 9 is set at the bottom of the squeezing chamber 4. A channel for fabric to be discharged is set on the right side of the squeezing chamber 4.

[0026] Specifically, such as Figure 1 and Figure 4 As shown, the servo motor 17 drives the threaded rod 19 to rotate, which in turn drives the two sets of threaded blocks 18 sleeved at both ends of the threaded rod 19 to move in opposite directions, thereby driving the two roller frames 20 fixedly connected to it to move synchronously, realizing the symmetrical adjustment of the movable guide roller group 5. When the fabric passes between the movable guide roller group 5, it is clamped and squeezed, thus completing the recovery of residual liquid from the dyed fabric.

[0027] A storage tank 6 is installed on the top right side of the dyeing chamber 9, and a return trough 8 is installed below the storage tank 6. The storage tank 6 and the return trough 8 are connected by a pipeline. The storage tank 6 and the dyeing chamber 9 are connected by a return pump. A level gauge 7 is installed on the right side of the return trough 8 to monitor the water level. A conveying roller 1 is installed on the left side of the constant temperature dyeing liquor tank 14. The conveying roller 1 and the fixed guide cloth roller group 2 are positioned in front and behind.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, the excess dye liquor generated after the fabric is squeezed, as well as the dye liquor soaked in the dyeing chamber 9, are collected in the storage tank 6. After being temporarily stored in the storage tank 6, the dye liquor is guided by the pipeline to the return tank 8 for centralized recycling. A level gauge 7 is installed on the right side of the return tank 8 to monitor the liquid level. When the liquid level exceeds the preset value, the system can control the dye liquor to stop recycling or pump it back into the constant temperature dye liquor tank 14 for recycling.

[0029] Working Principle: The dye liquor, heated at a constant temperature in the constant temperature dye bath tank 14, is drawn out by the dye pump 13 and then diverted by the distributor 16 into two spray frames 11. Multiple sets of nozzles 12 are evenly spaced within the spray frames 11, and each nozzle 12 is aimed at the front and back of the double-layer four-way stretch silk fabric. The dye liquor, heated at a constant temperature in the constant temperature dye bath tank 14, is diverted by the distributor 16 into the two spray frames 11, where the nozzles 12 evenly spray the fabric on both sides. The fabric travels along a "V" shaped path inside the dyeing chamber 9, and is supported by the dyeing rollers 10 to form a dye liquor surround, thereby improving the fabric's absorption efficiency. The dyed fabric is then discharged from the dyeing chamber 9 into the extrusion chamber 4, where it is processed by a servo motor. Motor 17 drives threaded rod 19 to rotate, causing two sets of threaded blocks 18 sleeved at both ends of threaded rod 19 to move in opposite directions, thereby driving the two roller frames 20 fixedly connected to it to move synchronously, realizing the symmetrical adjustment of movable guide roller group 5. When the fabric passes between movable guide roller group 5, it is clamped and squeezed to complete the recovery of residual liquid from the dyed fabric. The excess dye liquid generated after the fabric is squeezed, as well as the dye liquid soaked in dyeing chamber 9, flow into storage tank 6. After being temporarily stored in storage tank 6, it is guided by pipeline to return tank 8 for centralized recovery. A level gauge 7 is set on the right side of return tank 8 to monitor the liquid level. When the liquid level exceeds the preset value, the system can control the dye liquid to stop recovery or re-pump into constant temperature dye liquid tank 14 for recycling.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
