Detailed implementation manners

[0028] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, in which the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application, but should not be construed as limiting the present application.

[0029] The cotton yarn dyeing equipment of the embodiments of the present application will be described below with reference to the drawings.

[0030] The cotton yarn dyeing equipment provided by the present application is mainly applied to the process of dyeing cotton yarn blanks, and can reduce heat loss, extend the contact time between the cotton yarn blanks and the heat source, improve the drying effect, and improve the dyeing efficiency of the cotton yarn blanks when drying the cotton yarn blanks after dipping.

[0031] As Figures 1-5 shown, the cotton yarn dyeing equipment of the embodiments of the present application may include: a housing 1, an unwinding device 2, a dipping mechanism 3, a drying mechanism 4, and a winding device 5.

[0032] Among them, a first cavity 11 and a second cavity 12 are provided inside the housing 1.

[0033] It should be noted that a cover is provided on the second cavity 12 described in this embodiment. The cover can reduce the heat loss in the second cavity 12 and cooperate with the drying mechanism 4, which is equivalent to providing two layers of heat insulation mechanisms outside the heating rod 42, further improving the drying effect of this equipment.

[0034] The unwinding device 2 is arranged on one side of the housing 1, and the unwinding device 2 is used to release the to-be-dyed cotton yarn embryo at a uniform speed.

[0035] The dipping mechanism 3 is arranged inside the first cavity 11, and the dipping mechanism 3 may include a pressing component 32 and an auxiliary component 33.

[0036] Among them, a dipping bin 31 is arranged inside the first cavity 11. One end of the pressing component 32 is placed inside the dipping bin 31. The pressing component 32 is used to press down the cotton yarn embryo for dipping it and disturbing the dye in the dipping bin 31.

[0037] It should be noted that a dyeing solution is placed in the dipping bin 31 described in this embodiment. The dyeing solution is mixed with water, dyes, auxiliary agents such as calabash red, etc. Therefore, the dyes and auxiliary agents need to be processed before dyeing. The dyes go through processes such as screening, grinding, dissolving, and color matching to obtain the dyeing solution, and the auxiliary agents are added to the dyeing solution in a certain proportion.

[0038] As a possible situation, a liquid level indicator (not shown in the figure) is arranged inside the dipping bin 31. Relevant personnel (such as operators) can judge whether the dyeing solution in the dipping bin 31 is lacking by observing the liquid level indicator, and then supplement the dyeing solution in a timely manner.

[0039] The auxiliary component 33 is inclined and arranged inside the first cavity 11. One end of the auxiliary component 33 extends into the dipping bin 31, and the auxiliary component 33 is used to rub the cotton yarn embryo after dipping.

[0040] It should be noted that the auxiliary component 33 described in this embodiment is inclined and arranged inside the first cavity 11, and the inclination angle of the auxiliary component 33 can be any angle between 30° and 60°, and no specific limitation is made here.

[0041] It can be understood that the auxiliary component 33 is inclined and arranged, which can make the dyeing solution rubbed off by the auxiliary component 33 flow back into the dipping bin 31 along itself. One end of the auxiliary component 33 extends into the dipping bin 31. Utilizing the capillary self-suction effect of the auxiliary component 33, the auxiliary component 33 can smear the cotton yarn embryo.

[0042] The drying mechanism 4 is arranged inside the second cavity 12, and the drying mechanism 4 may include two base plates 41, heating rods 42, a revolving cover 43, and a partition plate 45.

[0043] Among them, two substrates 41 are installed on the inner wall of the second cavity 12, and a heating rod 42 is rotatably installed between the two substrates 41.

[0044] It should be noted that in this embodiment, the heating rod 42 is rotatably installed between the two substrates 41. Specifically, the outer wall of the heating rod 42 is rotatable, and the inner core of the heating rod 42 is fixed and penetrates through the inner wall of the housing 1.

[0045] As a possible situation, referring to Figure 5 , the bending angle of the cotton yarn embryo in the revolving cover 43 is large. In order to ensure the normal movement of the cotton yarn embryo, a rotary driving device (not shown in the figure) can be abutted on the outer wall of the heating rod 42. The rotary driving device can include a servo motor, a driving gear and a driven gear. The rotary driving device can drive the heating rod 42 to rotate at a constant speed, so as to provide power for the cotton yarn embryo inside the revolving cover 43.

[0046] As another possible situation, in order to further reduce the friction force of the cotton yarn embryo in the revolving cover 43, the revolving cover 43 and the partition plate 45 can be made of stainless steel metal material, which has a smooth surface and good heat conduction effect.

[0047] One end of the revolving cover 43 and the partition plate 45 are respectively connected to the outer walls of the two substrates 41, the revolving cover 43 and the partition plate 45 are respectively connected to the inner wall of the second cavity 12, and the revolving cover 43 is used to form a cylindrical cavity outside the heating rod 42.

[0048] It should be noted that there is a gap between one end of the revolving cover 43 and the partition plate 45 and the outer wall of the heating rod 42, and the cotton yarn embryo can pass through the gap.

[0049] In addition, referring to Figure 5 , when the cotton yarn embryo bypasses the outer wall of the heating rod 42, the cotton yarn embryo contacts the other end of the revolving cover 43 and moves along the outer wall of the revolving cover 43. The bending angle of the cotton yarn embryo at this contact position is large, and in addition, this position is in the high-temperature area inside the revolving cover 43. This contact position (the other end of the revolving cover 43) has an orthopedic effect on the cotton yarn embryo, making the dyed cotton yarn embryo straight and improving the quality of the cotton yarn.

[0050] It can be understood that the revolving cover 43 is used to form a cylindrical cavity outside the heating rod 42. The cylindrical cavity has an effect of accumulating heat, and the heat can be continuously reflected inside the cylindrical cavity, so as to improve the drying effect of the cotton yarn embryo in the revolving cover 43.

[0051] The partition plate 45 is located inside the revolving cover 43, and a cavity 46 is provided between the partition plate 45 and the revolving cover 43.

[0052] On the other side of the housing 1, there is a discharge port 50. The winding device 5 is arranged on the other side of the housing 1 and is disposed opposite to the discharge port 50.

[0053] Specifically, when relevant personnel (such as operators) dye cotton yarn embryos (such as cotton yarns, cotton sliver), first, place the wound cotton yarn embryos on the unwinding device 2. The relevant personnel pass one end of the cotton yarn embryo under the pressing component 32 and then place it into the auxiliary component 33. Then, open the cover on the second cavity 12, pass one end of the cotton yarn embryo through the inner cavity of the swirling cover 43, around the heating rod 42, and out from the inside of the cavity 46. Then, pass through the discharge port and finally place it on the winding device 5, and the cotton yarn embryo is wound up.

[0054] As a possible situation, in order to facilitate one end of the cotton yarn embryo to pass through the inner cavity of the swirling cover 43, around the heating rod 42, and out from the inside of the cavity 46, the partition plate 45 and the substrate 41 can be pivotally connected. As Figure 4 and Figure 5 shown, the position of the partition plate 45 is the locking position, and the partition plate 45 can be turned up. When the relevant personnel send the cotton yarn embryo into the swirling cover 43, manually flip the partition plate 45 to make the volume of the cavity 46 larger. The hand of the relevant personnel can reach in to bypass the heating rod 42 with the cotton yarn embryo and pass it out from the inside of the cavity 46. After that, when the cotton yarn embryo is tightened, the partition plate 45 can automatically reset.

[0055] Inject the prepared dyeing solution into the dipping bin 31, start the device. The cotton yarn embryo first passes through the pressing component 32. The pressing component 32 presses down on the cotton yarn embryo to dip it. During the self-rotation process of the pressing component 32, the pressing component 32 can disturb the dye in the dipping bin 31 to prevent precipitation of the dyeing solution in the dipping bin 31.

[0056] The cotton yarn embryo passes through the auxiliary component 33. Under the action of the auxiliary component 33, the excess dyeing solution on the surface of the cotton yarn embryo is blocked and flows back into the dipping bin 31, and the dyeing solution on the surface of the cotton yarn embryo is evenly applied.

[0057] The cotton yarn embryo enters the inside of the second cavity 12. Due to the action of the heating rod 42, a high-temperature area is formed in the swirling cover 43. The first side of the cotton yarn embryo is in continuous contact with the hot air in the swirling cover 43. At the same time, the second side of the cotton yarn embryo is in contact with the outer wall of the partition plate 45. Then, the second side of the cotton yarn embryo is in contact with the outer wall of the heating rod 42. The heating rod 42 rotates, and the cotton yarn embryo continues to move in the swirling cover 43. After that, the first side of the cotton yarn embryo is in contact with the outer wall of the swirling cover 43 until the cotton yarn embryo leaves the swirling cover 43. The dried cotton yarn embryo is wound around the external winding device 50 through the discharge port 50.

[0058] In the above process, the excellent temperature locking effect of the cylindrical vortex cover 43 is utilized to reduce heat loss and save energy. The cotton yarn embryo rotates and moves in the vortex cover 43 and contacts the vortex cover 43 and the partition plate 45 with high temperature. In addition, the cotton yarn embryo can also be turned over in the vortex cover 43, thereby shortening the drying time, improving the drying effect, and improving the efficiency of cotton yarn dyeing.

[0059] In the embodiments of the present application, multiple cotton yarn embryos can be dyed simultaneously, and the number of the multiple cotton yarn embryos can be 5, 7, 9, etc., which is not specifically limited here.

[0060] In one embodiment of the present application, Figure 1 and Figure 6 As shown, the pressing assembly 32 may include a roller 321 , a plurality of pressing plates 322 and a first driving device 323 .

[0061] Among them, the roller 321 is rotatably arranged on the inner wall of the dyeing chamber 31, multiple pressing plates 322 are respectively arranged on the outside of the roller 321, the first driving device 323 is arranged on the outer wall of the shell 1, and the output shaft of the first driving device 323 is connected to one end of the roller 321.

[0062] Specifically, during the operation of the pressing assembly 32, the first driving device 323 drives the roller 321 to rotate, and the roller 321 drives the multiple pressing plates 322 to rotate. The multiple pressing plates 322 can not only press down the cotton yarn embryo to immerse it in the dyeing liquid, but also disturb the dyeing liquid in the dyeing chamber 31, thereby avoiding the precipitation of the hot color liquid and ensuring the uniformity of the dyeing liquid.

[0063] In one embodiment of the present application, Figure 1 , Figure 2 and Figure 7 As shown, the auxiliary component 33 may include a frame 331 and a sponge 332 .

[0064] The frame 331 is disposed on the inner wall of the first cavity 11 , the sponge 332 is disposed inside the frame 331 , and a plurality of limiting slits 333 are formed on the sponge 332 .

[0065] Specifically, the cotton yarn embryo passes through the limiting slit 333 , and the sponge 332 can evenly spread the dyeing liquid on the cotton yarn embryo, and the excess dyeing liquid can flow back to the inside of the dyeing chamber 31 .

[0066] It is understandable that the frame 331 can limit the sponge 332 to facilitate the later replacement of the sponge 332 , and can receive the dyeing liquid to ensure that the dyeing liquid flows back to the interior of the dyeing chamber 31 .

[0067] In one embodiment of the present application, Figure 3 andFigure 4 As shown, a guiding portion 44 is provided on the rotary cover 43.

[0068] It can be understood that setting the guiding portion 44 can reduce the acting force between the cotton yarn embryo and the rotary cover 43 when the cotton yarn embryo enters the rotary cover 43, so as to ensure that the cotton yarn embryo can move at a uniform speed within the rotary cover 43.

[0069] In an embodiment of the present application, as Figure 3 shown, a plurality of exhaust holes 47 are formed on the outer wall of the rotary cover 43.

[0070] It can be understood that the cotton yarn embryo is dried inside the high-temperature rotary cover 43. At the same time, the water vapor carried by the cotton yarn embryo enters the air. In order to prevent the formation of a high-humidity area inside the rotary cover 43, the water vapor can overflow through the exhaust holes 47 in time, and the heat loss caused by this process can be ignored compared with the heat required for drying.

[0071] In an embodiment of the present application, as Figure 1 and Figure 8 shown, the unwinding device 2 may include two brackets 21, two fixed chucks 22 and two dampers 23.

[0072] Among them, the two brackets 21 are respectively installed on the outer wall of the housing 1, the two fixed chucks 22 are respectively installed on the corresponding brackets 21, and the two dampers 23 are respectively installed on the corresponding fixed chucks 22.

[0073] It can be understood that installing the damper 23 on the fixed chuck 22 can limit the rotation speed of the fixed chuck 22, so that the unwinding device 2 can release the cotton yarn embryo to be dyed at a uniform speed.

[0074] In an embodiment of the present application, as Figure 1 and Figure 9 shown, the winding device 5 may include two mounting plates 51, a second driving device 52 and a positioning device 53.

[0075] Among them, the two mounting plates 51 are respectively arranged on the outer wall of the housing 1, the second driving device 52 is arranged on one mounting plate 51, and the positioning device 53 is arranged on the other mounting plate 51.

[0076] It can be understood that setting the positioning device 53 facilitates the replacement of the cotton yarn roller after winding. The second driving device 52 and the winding roller shaft can be connected in a detachable manner, for example: pin connection.

[0077] Specifically, before dyeing the cotton yarn embryo, the roller shaft with the cotton yarn embryo can be placed between two fixed chucks 22, and another roller shaft can be placed between the second driving device 52 and the positioner 53. During the dyeing process, the second driving device 52 operates, and the second driving device 52 drives the other roller shaft to rotate. Under the pulling action of the cotton yarn embryo, the roller shaft with the cotton yarn embryo rotates freely to release the cotton yarn embryo. Under the action of the damper 23, the roller shaft with the cotton yarn embryo rotates at a constant speed, and the cotton yarn embryo remains taut inside the housing 1. After the other roller shaft finishes winding, the positioner 53 at one end of the other roller shaft can be removed, and the connection between the output shaft of the second driving device 52 and the other roller shaft can be removed, so as to unload the wound cotton yarn embryo and replace it with a new roller shaft at the same time.

[0078] In an embodiment of the present application, as Figure 1 and Figure 2 shown, a first guiding roller 61 is rotatably connected to the inner wall of the housing 1. The first guiding roller 61 is arranged close to the unwinding device 2. A through groove 62 is formed between the first cavity 11 and the second cavity 12, and a second guiding roller 63 is rotatably arranged inside the through groove 62.

[0079] It can be understood that both the first guiding roller 61 and the second guiding roller 63 can increase the contact area, reduce the acting force between the housing 1 and the cotton yarn embryo, and ensure the cotton yarn embryo moves at a constant speed inside the housing 1.

[0080] In summary, the cotton yarn dyeing equipment of the embodiment of the present application utilizes the excellent temperature-locking effect of the cylindrical rotary cover to reduce heat loss and save energy use. The cotton yarn embryo moves in a rotary manner inside the rotary cover and contacts the high-temperature rotary cover and the partition plate. In addition, the cotton yarn embryo can also be turned over inside the rotary cover, thereby shortening the drying time, improving the drying effect, and enhancing the efficiency of cotton yarn dyeing.
