The following will be described with reference to the accompanying drawings.

[0034] The cut piece flat width dyeing device 10 provided in the embodiment of the present application is exemplary, see Figure 1 As shown, Figure 1 The schematic diagram of the structure of the cut piece flat width dyeing device 10 provided in the embodiment of the present application. The cut piece flat width dyeing device 10 of the present application can be used for dyeing various clothing cut pieces such as collar cut pieces 20. The structure of the cut piece flat width dyeing device 10 will be described below according to the processing of the collar cut piece 20.

[0035] In order to more clearly illustrate the structure of the cut piece flat width dyeing device 10 , the cut piece flat width dyeing device 10 will be introduced below with reference to the accompanying drawings.

[0036] For example, see Figure 1 As shown, the cut piece flat width dyeing device 10 comprises a machine platform 100 and a main dyeing tank 200, a rotating roller 300, a spraying pipe 400, a circulating pump 500 and a control device installed on the machine platform 100. The control device can be a PLC programmable logic controller.

[0037] The rotating roller 300 is located in the main dyeing vat 200 for sleeve-mounting the collar and cuff pieces 20. The rotating roller 300 can rotate relative to the main dyeing vat 200. The spray pipe 400 is arranged in the main dyeing vat 200 and is arranged opposite to the rotating roller. The axial direction of the spray pipe 400 is parallel to the axial direction of the rotating roller 300. The main dyeing vat 200 and the spray pipe 400 are connected through the circulation pipe 600. The circulation pump 500 is connected to the circulation pipe 600 between the main dyeing vat 200 and the spray pipe 400 to realize circulation spraying. The circulation pump 500 is electrically connected to the control device.

[0038] In some of these examples, see Figure 1 As shown, the rotating roller 300 includes a wheel disc 301, a rotating rod 302 and a supporting plate 303. There are multiple rotating rods 302, both ends of which are connected to the wheel disc 301. The multiple rotating rods 302 are distributed along a circular ring, and the multiple rotating rods 302 and the wheel disc 301 form a cylindrical structure as a whole. The supporting plate 303 is sleeved on each rotating rod 302, and the supporting plate 303 is used to support the multiple rotating rods 302. The wheel disc 301 and the supporting plate 303 are both flat disc structures.

[0039] In some embodiments, the support disk 303 is located between the two wheel disks 301 and in the middle of the rotating rod 302. The number of the support disks 303 can be one or more.

[0040] In one embodiment, see Figure 1 As shown, the radius of the ring formed by the multiple rotating rods 302 is set as needed. For example, the radius of the ring formed by the multiple rotating rods 302 is 10-30 cm. The roller surface of the rotating roller 300 formed by the multiple rotating rods 302 has a certain curvature to be able to support the collar cut piece 20.

[0041] In some embodiments, the spray pipe 400 is disposed at an upper position of the rotating roller 300. The spray pipe 400 is disposed at an upper position of the rotating roller 300 so that the dyeing liquid in the spray pipe 400 can be sprayed out under the action of its own weight and pressure.

[0042] In some embodiments, a plurality of spray holes are provided at the bottom of the spray pipe 400. The diameter of the spray hole is set according to actual needs. The number of spray holes is based on the number of holes covering the entire bottom surface of the spray pipe 400, so that the entire upper roller surface of the rotating roller 300 can be covered during spraying to ensure spray uniformity.

[0043] In some embodiments, the length of the spray pipe 400 is not less than the length of the rotating roller 300. Preferably, the length of the spray pipe 400 is equal to the length of the rotating roller 300. This ensures that each position along the length direction of the rotating roller 300 can be soaked and contacted by the dyeing liquid sprayed from the spray pipe 400, thereby improving the dyeing efficiency and dyeing quality.

[0044] In some of these examples, see Figure 1 and Figure 2 As shown, the cut piece flat width dyeing device 10 also includes a secondary dyeing vat 700. The secondary dyeing vat 700 is installed on the machine platform 100, and the secondary dyeing vat 700 is connected to the main dyeing vat 200 through a feeding pipe 800. A control valve is provided on the feeding pipe 800 between the secondary dyeing vat 700 and the main dyeing vat 200. The secondary dyeing vat 700 is used to add dyes and auxiliaries. When the concentration of the dyeing liquid in the main dyeing vat 200 decreases, by adding dyes and auxiliaries to the secondary dyeing vat 700, the dyes and auxiliaries in the secondary dyeing vat 700 enter the main dyeing vat 200 to increase the concentration of the dyeing liquid to a predetermined range.

[0045] In some embodiments, the volume of the auxiliary dyeing vat 700 is smaller than that of the main dyeing vat 200. The auxiliary dyeing vat 700 is located outside the main dyeing vat 200.

[0046] In some embodiments, the number of the auxiliary dyeing vats 700 may be one or more. Figure 2 As shown, the number of the auxiliary dyeing tank 700 is shown as one.

[0047] In some of these examples, see Figure 1 and Figure 2 As shown, the cut piece flat width dyeing device 10 further includes a stirring mechanism 900. The stirring mechanism 900 is mounted on the machine platform 100, and a stirring shaft of the stirring mechanism 900 is at least partially located in the auxiliary dyeing tank 700.

The stirring mechanism 900 is electrically connected to the control device.

[0048] In some embodiments, the cut piece flat width dyeing device 10 further includes a heat exchanger 1000. The heat exchanger 1000 is installed on the circulation pipeline 600 to adjust the temperature of the dyeing liquid in the main dyeing tank 200.

[0049] In some of the embodiments, the auxiliary dyeing vat 700 is further connected to the circulation pipe 600 through a pipe, and the water in the circulation pipe 600 can enter the auxiliary dyeing vat 700 as a solvent.

[0050] In some embodiments, the cut piece flat width dyeing device 10 further includes a steam pipe 1100 and a steam proportional valve 1200. The steam pipe 1100 is connected to the circulation pipe 600, and the steam proportional valve 1200 is connected to the steam pipe 1100 to control the heating rate. The steam pipe 1100 is used to connect to an external steam source.

[0051] In some embodiments, the cut piece flat width dyeing device 10 further includes a drain pipe 1300 and a drain valve 1400. One end of the drain pipe 1300 is connected to the heat exchanger 1000 for discharging steam condensate during heating, and the drain valve 1400 is disposed on the drain pipe 1300. The other end of the drain pipe 1300 is used for external discharge.

[0052] In some embodiments, the cut piece flat width dyeing device 10 further includes a drainage pipe 1500 and a drainage valve 1600. One end of the drainage pipe 1500 is connected to the heat exchanger 1000 to discharge the cooling water after the heat exchanger 1000, and the drainage valve 1600 is disposed on the drainage pipe 1500. The other end of the drainage pipe 1500 is used for external drainage.

[0053] In some of these examples, see Figure 4 As shown, the cut piece flat width dyeing device 10 also includes a plurality of spray grids 1700. The spray grids 1700 are arranged in the spray pipe 400 and divide the spray pipe 400 into equal parts. The spray grids 1700 do not completely enclose the spray pipe 400. The lower part of the spray grid 1700 is sealed and connected to the spray pipe 400. The upper part of the spray grid 1700 is at a certain distance from the top of the spray pipe 400 to facilitate the entry of the dyeing liquid. The spray grids 1700 have the function of reinforcing the spray pipe 400 so that it is not easily deformed, and on the other hand, they can evenly separate the dyeing liquid.

[0054] In some of these embodiments, see Figure 3As shown, the cut piece flat width dyeing device 10 also includes a correction rod 1800 and a correction drive component 1900. The correction rod 1800 is arranged in the main dyeing tank 200, and the correction drive component 1900 is installed on the machine 100 and connected to the correction rod 1800. The correction drive component 1900 is used to drive the correction rod 1800 to swing to generate tension on the leader cut piece 20. The correction drive component 1900 is electrically connected to the control device. The correction rod 1800 is U-shaped, and the two ends of the correction rod 1800 are rotatably connected to the inner wall of the main dyeing tank 200. When the leader piece 20 in the main dye vat 200 is offset, the dyeing effect will be affected. The correcting rod 1800 is driven to rotate by the correcting driving component 1900. Since the correcting rod 1800 is U-shaped, the leader piece 20 can be propped up when the correcting rod 1800 swings. The swinging action of the correcting rod 1800 will lift the leader piece 20 to a certain angle, thereby increasing the unilateral tension of the leader piece 20. The leader piece 20 is straightened through the tension difference on both sides of the leader piece 20.

[0055] In some of these embodiments, see Figure 3 As shown, the deflection correction driving component 1900 can be a telescopic cylinder. In this case, the cut piece flat width dyeing device 10 further includes a swing rod 2300, one end of which is connected to the end of the deflection correction rod 1800, and the other end is connected to the deflection correction driving component 1900. When the deflection correction driving component 1900 is extended and retracted, it can pull the deflection correction driving component 1900 to swing and rotate, and the rotation of the swing rod 2300 drives the deflection correction rod 1800 to rotate.

[0056] In some embodiments, there are two deflection correction drive components 1900. The two deflection correction drive components 1900 are respectively arranged on the opposite side walls of the main dyeing vat 200, and the two deflection correction drive components 1900 are respectively connected to the two ends of the deflection correction rod 1800, and the deflection correction drive components 1900 are used to drive the deflection correction rod 1800 to rotate through telescopic movement. The deflection correction drive components 1900 are arranged as two deflection correction drive components 1900 that can apply force to the deflection correction rod 1800 from both ends of the deflection correction rod 1800, so as to improve the deflection correction effect and the dyeing effect.

[0057] In some embodiments, the cut piece flat width dyeing device 10 also includes a deviation detection component. The deviation detection component includes a deviation correction electric eye 2000 and a deviation stroke rod 2100. The deviation correction electric eye 2000 is electrically connected to the control device. The deviation stroke rod 2100 is an L-shaped structure, one end of the deviation stroke rod 2100 is located in the main dyeing tank 200, and the other end of the deviation stroke rod 2100 is located outside the main dyeing tank 200. The deviation stroke rod 2100 is also rotatably connected to the main dyeing tank 200. When the collar cut piece 20 deviates, the collar cut piece 20 squeezes the deviation stroke rod 2100, and the deviation stroke rod 2100 rotates so that the deviation stroke rod 2100 blocks the deviation correction electric eye 200. At this time, the control device controls the deviation correction drive component 1900 to act.

[0058] In some embodiments, the cut piece flat width dyeing device 10 further includes a roller driving component 2200. The roller driving component 2200 is installed on the machine platform 100 and connected to the rotating roller 300. The roller driving component 2200 is used to drive the rotating roller 300 to rotate at a predetermined speed. The roller driving component 2200 is electrically connected to the control device.

[0059] In some of these embodiments, the roller driving component 2200 can be a driving motor.

[0060] When used, the above-mentioned cut piece flat width dyeing device 10 comprises the following steps:

[0061] See also Figure 1 and Figure 3 As shown, multiple collar pieces 20 are connected to form an annular structure, and the connection method can be sewing thread connection. Multiple sewing threads can be connected between adjacent collar pieces 20 to ensure that the collar pieces 20 will not break. During dyeing, the collar pieces 20 formed by the connection to form an annular structure are sleeved on the rotating roller 300, and the roller surface of the rotating roller 300 can support the collar piece 20. Add the corresponding dye and auxiliary agent into the auxiliary dyeing vat 700, add solvent water into the auxiliary dyeing vat 700, and the dye and auxiliary agent are dissolved to form a dyeing liquid, and the dyeing liquid is added into the main dyeing vat 200.

[0062] The rotating driving component is controlled to drive the rotating roller 300 to rotate at a predetermined speed, and the circulating pump 500 is controlled to start and spray the dyeing liquid from the spray pipe.

[0063] See also Figure 3 As shown, when the leader panel 20 is offset, the correcting driving component 1900 drives the rocker arm 2300 to rotate, and the rocker arm 2300 drives the correcting rod 1800 to swing. When the correcting rod 1800 swings, the leader panel 20 can be propped up. The swinging action of the correcting rod 1800 will lift the leader panel 20 to a certain angle, thereby increasing the unilateral tension of the leader panel 20, and the leader panel 20 is straightened through the tension difference on both sides of the leader panel 20.

[0064] During the dyeing process of the collar cut piece 20, when the temperature of the dyeing liquid decreases, steam is introduced through the steam pipe 1100, and the steam exchanges heat through the heat exchanger 1000. The condensed water of the steam when the temperature rises is discharged through the drain pipe 1300.

[0065] After the dyeing time is set,

[0066] In summary, the above-mentioned cut piece flat-width dyeing device 10 can dye the collar in a flat-width posture, and has a simple, compact, stable structure, high efficiency, and high degree of automation. The above-mentioned cut piece flat-width dyeing device 10 is suitable for flat-width dyeing of collars in the textile industry, and has very positive significance.
