Description

Technical Field

[0001] This utility model relates to the field of garment dyeing technology, and in particular to a low-liquor-ratio, crease-free, seamless underwear garment dyeing machine. Background Technology

[0002] A garment dyeing machine is a device used to dye various knitted finished products. It is widely used in the dyeing and finishing processes of garments and seamless underwear, socks, T-shirts, and other products made of fibers such as wool, polyester, nylon, and rayon. Its purpose is to dye white clothing into different colors as needed. The process mainly includes washing, dyeing, sizing, rinsing, and dehydration. When the garment dyeing machine is working, to achieve the ideal dyeing effect, the temperature, water volume, and dyeing time in the dyeing tank must be precisely controlled according to the requirements of the dyeing process.

[0003] Existing seamless underwear dyeing machines use agitator blades within a dyeing vat to dye the seamless underwear. The heat exchanger is typically located at the bottom of the vat, which is made of stainless steel. However, this system has two drawbacks: First, the agitator blades result in a high dyeing liquor ratio (the ratio of the mass of the garment to the mass of water during dyeing), requiring the dye liquor to completely immerse the seamless underwear. Second, seamless underwear is prone to creases. These creases are caused by two factors: firstly, friction between the stainless steel vat and the seamless underwear creates different frictional forces at the contact points compared to the non-contact areas; secondly, the bottom heat exchanger creates a temperature difference between the water at the bottom and above, leading to uneven shrinkage and shrinkage creases in the seamless underwear. Utility Model Content

[0004] The purpose of this invention is to provide a low-liquor-ratio, crease-free, seamless underwear dyeing machine to address the aforementioned shortcomings in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A low-liquor-ratio, crease-free, seamless underwear dyeing machine includes a frame and a cylinder disposed on the frame, and further includes:

[0007] An annular rotating body is provided, wherein the cylinder is horizontally mounted on the frame and the annular rotating body is rotatably connected to the inside of the cylinder. A cylindrical staining chamber is formed inside the annular rotating body, and an annular collection chamber communicating with the cylindrical staining chamber is formed between the annular rotating body and the inner wall of the cylinder. A driving mechanism is provided on the frame, and the annular rotating body is driven by the driving mechanism to rotate inside the cylinder.

[0008] The spraying mechanism includes a spraying element and a liquid circulation assembly. The spraying element is disposed on the annular rotating body and has a spraying structure for spraying dye liquid into the seamless underwear in the cylindrical dyeing chamber. A heat exchanger and a circulation pump are disposed on the outside of the cylinder. The dye liquid in the annular liquid collection chamber flows back to the spraying element through the heat exchanger and the circulation pump.

[0009] The aforementioned low-liquor-ratio, crease-free, seamless underwear dyeing machine has a liquid outlet on its cylinder body, which is located at the bottom of the cylindrical dyeing chamber. The liquid outlet is connected to the circulating pump via a liquid outlet pipe.

[0010] The aforementioned low-liquor-ratio, crease-free, seamless underwear dyeing machine has a liquid inlet on its cylinder, which is connected to the water outlet of the heat exchanger, and the water inlet of the heat exchanger is connected to the circulating pump.

[0011] The aforementioned low-liquor-ratio, crease-free, seamless underwear dyeing machine includes a rotating cage comprising a central component and an annular cage body surrounding the central component.

[0012] The aforementioned low-liquor-ratio, crease-free, seamless underwear dyeing machine includes a spray component comprising axial spray rods disposed on the inner side wall of the annular cage. There are multiple axial spray rods, which are arranged sequentially at intervals along the circumference of the annular cage.

[0013] The aforementioned low-liquor-ratio, crease-free, seamless underwear dyeing machine features a spray structure consisting of spray holes arranged on the axial spray rod. Multiple sets of these spray holes are sequentially spaced along the length of the axial spray rod.

[0014] In the aforementioned low-liquor-ratio, crease-free, seamless underwear dyeing machine, the axial spray bar is connected to the central component via a radial connecting rod.

[0015] The aforementioned low-liquor-ratio, crease-free, seamless underwear dyeing machine includes a liquid channel within the central component, which is connected to the liquid inlet; a radial channel within the radial connecting rod; and an axial channel within the axial spray rod. The axial channel is connected to the radial channel, and the radial channel is connected to the liquid channel.

[0016] The aforementioned low-liquor-ratio, crease-free, seamless underwear dyeing machine has a reflux hole on the annular cage, and the cylindrical dyeing chamber is connected to the annular liquid collection chamber through the reflux hole.

[0017] In the above technical solution, the low liquor ratio seamless underwear dyeing machine provided by this utility model includes a frame and a cylinder set on the frame. The cylinder is horizontally installed on the frame, and an annular rotating body is rotatably connected to the inside of the cylinder. A cylindrical dyeing chamber is formed inside the annular rotating body, and an annular liquid collection chamber connected to the cylindrical dyeing chamber is formed between the annular rotating body and the inside of the cylinder. A spraying component is provided on the annular rotating body, and a heat exchanger and a circulation pump are provided on the outside of the cylinder.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-2As shown, this utility model provides a low-liquor-ratio, crease-free seamless underwear dyeing machine, including a frame and a cylinder 1 mounted on the frame, as well as an annular rotating body 2 and a spraying mechanism 4. The cylinder 1 is horizontally mounted on the frame, and the annular rotating body 2 is rotatably connected to the inside of the cylinder 1. A cylindrical dyeing chamber 13 is formed inside the annular rotating body 2, and an annular liquid collection chamber 14 is formed between the annular rotating body 2 and the inner wall of the cylinder 1. A driving mechanism 3 is provided on the frame, and the annular rotating body 2 can rotate inside the cylinder 1 under the drive of the driving mechanism 3. The spraying mechanism 4 includes a spraying component and a liquid circulation assembly. The spraying component is mounted on the annular rotating body 2 and has a spraying structure for spraying dye into the seamless underwear in the cylindrical dyeing chamber 13. A heat exchanger 5 and a circulation pump 6 are provided on the outside of the cylinder 1, and the dye in the annular liquid collection chamber 14 flows back to the spraying component through the heat exchanger 5 and the circulation pump 6.

[0025] Specifically, the frame is used to install the cylinder 1 and the drive mechanism 3. The cylinder 1 is horizontally installed on the frame. An annular rotating body 2 is provided inside the cylinder 1. The annular rotating body 2 is coaxially arranged with the cylinder 1. The drive mechanism 3 is set on the frame. The annular rotating body 2 is driven by the drive mechanism 3 and can rotate inside the cylinder 1. A cylindrical dyeing cavity 13 is formed inside the annular rotating body 2. An opening is provided on one side of the cylinder 1. The seamless underwear to be dyed can be placed in the cylindrical dyeing cavity 13 through the opening. An annular liquid collection cavity 14 is formed between the annular rotating body 2 and the inner wall of the cylinder 1. The annular liquid collection cavity 14 is arranged around the cylindrical dyeing cavity 13 and is connected to the cylindrical dyeing cavity 13.

[0026] In this embodiment, a spraying mechanism 4 is also provided on the annular rotating body 2. The spraying mechanism 4 can spray dye liquid onto the seamless underwear located in the cylindrical dyeing chamber 13. The spraying mechanism 4 includes spraying elements, which are installed on the annular rotating body 2 and parallel to the axis of the cylinder 1. The number of spraying elements is set as needed. A spraying structure is provided on the spraying elements. The spraying structure can be a nozzle or a spray hole 42. The spraying mechanism 4 also includes a dye liquid circulation assembly, which includes a heat exchanger 5 and a circulation pump 6. Both the heat exchanger 5 and the circulation pump 6 are located on the outside of the cylinder 1 to realize heat exchange treatment of the sprayed dye liquid and continue to transport it to the spraying elements. The heat exchanger 5 and the circulation pump 6 are existing technologies and will not be described in detail.

[0027] In this embodiment, the circulating pump 6 is also connected to the dye liquor delivery mechanism. During use, the seamless underwear to be dyed is first placed in the cylindrical dyeing chamber 13. In the initial state, the circulating pump 6 is connected to the dye liquor delivery mechanism, which delivers the dye liquor required for dyeing. The dye liquor passes through the heat exchanger 5 to make its temperature meet the requirements. Then, the dye liquor is sprayed onto the seamless underwear in the cylindrical dyeing chamber 13 through the spraying component. The sprayed dye liquor cup is delivered to the annular collection chamber 14. When the dye liquor in the annular collection chamber 14 reaches a certain amount, the dye liquor delivery mechanism stops delivering the dye liquor. At this time, the circulating pump 6 recovers the dye liquor in the annular collection chamber 14 and delivers it to the heat exchanger 5. The heat exchanger 5 adjusts the temperature to form a dye liquor at a suitable temperature. The dye liquor at the suitable temperature is then delivered to the spraying component for spray dyeing.

[0028] The present invention provides a low-liquor-ratio, crease-free seamless underwear dyeing machine, including a frame and a cylinder 1 mounted on the frame. The cylinder 1 is horizontally mounted on the frame, and an annular rotating body 2 is rotatably connected to the inside of the cylinder 1. A cylindrical dyeing chamber 13 is formed inside the annular rotating body 2, and an annular liquid collection chamber 14 communicating with the cylindrical dyeing chamber 13 is formed between the annular rotating body 2 and the inside of the cylinder 1. A spraying component is provided on the annular rotating body 2, and a heat exchanger 5 and a circulating pump 6 are provided on the outside of the cylinder 1. The heat exchanger 5 allows the heating and cooling of the dye liquor to take place outside the cylinder 1, so that the dye liquor enters the inside of the cylinder 1 at a uniform temperature, avoiding the local shrinkage difference of the seamless underwear caused by temperature differences, thereby avoiding shrinkage creases in the seamless underwear. The annular rotating body 2 drives the dye liquor and the seamless underwear to rotate synchronously, and the dye liquor is sprayed evenly on the seamless underwear. The dye liquor does not need to soak the seamless underwear, so the mass ratio of the garment to the dye liquor can be reduced.

[0029] In this embodiment, preferably, the cylinder 1 is provided with an outlet 11 and an inlet 12. The outlet 11 is located at the bottom of the annular dyeing chamber and is connected to the circulation pump 6 through an outlet pipe. The inlet 12 is connected to the water outlet of the heat exchanger 5 and the water inlet of the heat exchanger 5 is connected to the circulation pump 6. Thus, the outlet 11, outlet pipe, circulation pump 6, heat exchanger 5, inlet 12 and spraying components are connected in sequence to realize the recycling of dye liquor. The dye liquor can be temporarily stored in the cylindrical dyeing chamber 13 until a certain amount is reached. When the dye liquor in the cylindrical dyeing chamber 13 reaches a certain amount, it is transported to the annular collection chamber 14. This ensures that a certain amount of dye liquor is always maintained in the cylindrical dyeing chamber 13, thereby improving the dyeing effect.

[0030] In another embodiment of this utility model, preferably, the annular rotating body 2 includes a rotating cage 21, which is made of stainless steel and has a polytetrafluoroethylene coating inside with a coating thickness of 0.3-0.5mm. This coating avoids friction between the seamless underwear and the stainless steel material. The polytetrafluoroethylene coating reduces the friction between the seamless underwear and the dyeing vat, preventing creases caused by friction. The rotating cage 21 includes a central component 22 and an annular cage body 23 surrounding the central component 22. The annular cage body 23 is fixedly connected to the central component 22. The spraying component includes axial spraying rods 41 disposed on the inner sidewall of the annular cage body 23. The axial spraying rods 41 are arranged in a direction parallel to the axis of the cylinder 1. There are multiple axial spraying rods 41, which are arranged sequentially at intervals along the circumference of the annular cage body 23. By setting multiple axial spraying rods 41, the spraying effect can be improved.

[0031] In another embodiment of this utility model, preferably, the spraying structure is a spray hole 42 provided on the axial spraying rod 41. There are multiple sets of spray holes 42, which are arranged sequentially at intervals along the length direction of the axial spraying rod 41. The spray holes 42 on each axial spraying rod 41 have different directions. In this way, when the rotating cage 21 is driven to rotate, multiple axial spraying rods 41 can spray dye liquid in different directions, thereby improving the dyeing effect on seamless underwear.

[0032] In another embodiment of this utility model, preferably, the axial spray rod 41 is connected to the central member 22 via the radial connecting rod 24. The central member 22 is provided with a liquid channel, which is connected to the liquid inlet 12. The radial connecting rod 24 is provided with a radial channel, and the axial spray rod 41 is provided with an axial channel. Each spray hole 42 is connected to the axial channel. The axial channel is connected to the radial channel, and the radial channel is connected to the liquid channel. Thus, when the heat exchanger 5 delivers the dye liquor to each liquid inlet 12, the dye liquor sequentially passes through the liquid channel and the radial channel into each axial channel, and finally sprays out from each spray hole 42.

[0033] In another embodiment of this utility model, preferably, the annular cage 23 is provided with reflux holes, and multiple reflux holes are arranged sequentially along the circumference of the annular cage 23. The reflux holes enable communication between the cylindrical dyeing chamber 13 and the annular collection chamber 14. The multiple reflux holes can be arranged on the circumferential sidewall of the annular cage 23. The diameter of the reflux holes is 5-8 mm, and the spacing between the reflux holes is 18.5 mm. In this way, the dyeing liquid sprayed by the spray rod will enter the cylindrical dyeing chamber 13 and then be transported from the cylindrical dyeing chamber 13 to the annular collection chamber 14.

[0034] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
