DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0032] Embodiment 1:

[0033] See also Figure 1-6 The present invention provides a technical solution: a blended yarn dyeing device, comprising a dyeing box 1, a telescopic member 2 is installed on the side of the dyeing box 1, and a box cover 3 is connected to the telescopic member 2, and a receiving plate 39 is connected to both sides of a support frame 8, such as Figure 1 As shown, the box cover 3 can be driven to move up or down by the extension and retraction of the telescopic member 2, so that when moving up, the upper part of the dyeing box 1 can be opened to facilitate the loading and unloading of the blended yarn, and when moving down, the dyeing box 1 can be covered to facilitate the dyeing.

[0034] A telescopic member 4 is installed at the bottom of the dyeing box 1, and a support frame 8 is connected to the telescopic member 4. The upper and lower sides of the support frame 8 are rotatably connected to rollers 9. A driving component is provided on the support frame 8, and the driving component is used to drive the upper and lower rollers 9 to rotate synchronously.

[0035] Connecting rods 7 are connected to the inner walls of both sides of the support frame 8, and a support frame 6 is connected between the two connecting rods 7. The two ends of the support frame 6 are rotatably mounted on the upper and lower rollers 9 respectively. A lifting plate 5 is connected to the support frame 6. The support frame 8 is indirectly connected to the telescopic part 2 4 through the connection between the lifting plate 5 and the telescopic part 2 4.

[0036] like Figure 2 As shown, by the extension and retraction of the telescopic member 2 4, the lifting plate 8 is driven to move up and down, and the support frame 6, the support frame 8 and the roller 9 can be lifted up or dropped together, and cooperate with the control of the box cover 3 to realize the loading and unloading operations of the blended yarn when the box cover 3 and the support frame 8 are both lifted up, or the dyeing when they are both dropped. Moreover, since the support frame 6 is sleeved on the center of the roller 9, when the blended yarn is laid and loaded, it can be carried out synchronously on both sides of the roller 9, thereby improving the operating efficiency.

[0037] The lifting plate 5 is connected to a plurality of support frames 6 at equal intervals in the extending length direction, and the cross section of the roller 9 is a rounded triangle. Figure 2 and 3 As shown, multiple groups of support frames 8 and structures thereon can be installed and connected under a lifting plate 5, and multiple groups can be used together at the same time, and can be synchronously controlled through fewer telescopic parts 24, which simplifies the structure, reduces the use of driving parts, and improves efficiency. The rounded triangle cross-section of the roller 9 can prevent the blended yarn from slipping on the surface of the roller 9.

[0038] The driving assembly includes a servo motor 10, a sprocket 11, and a chain 12. The servo motor 10 is installed on the support frame 8, and the output end of the servo motor 10 is connected to the roller 9. The sprocket 11 is sleeved on both ends of the roller 9, and the chain 12 is sleeved on the outside of the sprocket 11.

[0039] like Figure 3 As shown, by controlling the servo motor 10 connected to the upper roller 9 to operate, the lower roller 9 can be synchronously driven to rotate through the cooperation of the sprocket 11 and the chain 12.

[0040] The inner wall of the dyeing box 1 is connected to a support platform 40, which supports the lower end of the receiving plate 39, so that when the telescopic member 24 drives the support frame 8 to move downward, the receiving plate 39 thereon can cooperate with the support platform 40 for support, thereby improving the stability of the overall operation.

[0041] Squeezing rollers 27 slidably connected to the support frame 8 are arranged on both sides of the rotating roller 9, and cams 13 are connected to the two ends of the rotating roller 9 on the lower side. A triangular top frame 15 and a slide plate 17 are slidably connected to the bottom of the dyeing box 1. The cam 13 and the slide plate 17 are slidably connected, and the triangular top frame 15 and the squeezing roller 27 are slidably connected. A gear linkage assembly is also arranged between the triangular top frame 15 and the slide plate 17. The gear linkage assembly is used to push the triangular top frame 15 to move up when the cam 13 cooperates with the slide plate 17 and drives the slide plate 17 to move down, so as to push the squeezing rollers 27 on both sides away from each other. A stirring assembly is also arranged in the dyeing box 1, and the stirring mechanism operates when the slide plate 17 slides down to stir the dye liquid in the dyeing box 1.

[0042] Furthermore, the bottom of the dyeing box 1 is connected with a round table 38, and the round table 38 is connected with a guide slide bar 14. The triangular top frame 15 is slidably sleeved on the outer side of the guide slide bar 14, and the lower end of the triangular top frame 15 cooperates with the round table 38. Figure 3 As shown, there are two guide slide bars 14, which are located on both sides of the triangular top frame 15 and are slidably mounted therewith, so as to increase the stability of the triangular top frame 15 when it slides up and down, and the round table 38 can limit the downward movement of the triangular top frame 15, so that it has a certain downward movement stagnation point under the action of gravity.

[0043] The bottom of the dyeing box 1 is connected to a guide slide bar 2 16, and a slide plate 17 is slidably sleeved on the outside of the guide slide bar 2 16, and a spring 18 is also sleeved on the outside of the guide slide bar 2 16, and the two ends of the spring 18 are respectively connected to the bottom of the dyeing box 1 and the slide plate 17, such as Figure 3 and 5 As shown, the guide slide rods 16 are also provided in two numbers, and stabilize the up and down movement of the slide plate 17. The spring 18 can generate an upward elastic force on the slide plate 17, so that the slide plate 17 is in a high position. In this way, when the support frame 8 falls to the receiving plate 39 and the support platform 40 for support, the cam 13 can just cooperate with the slide plate 17 in sliding under the rotation of the roller 9, and push the slide plate 17 to overcome the elastic force of the spring 18 to slide up and down.

[0044] Further, the gear linkage assembly includes a rack 19 and a rack 20. The bottom of the dyeing box 1 is rotatably connected to a gear set 21 through a bearing seat. The rack 19 is connected to the slide plate 17, and the rack 20 is connected to the triangular top frame 15. The rack 19 and the rack 20 are respectively located on both sides of the gear set 21 and meshed with the gear set 21. Figure 3 and 5As shown, when the slide plate 17 is driven to slide up and down, the rack 19 and the rack 20 can be respectively meshed with the two sides of the gear set 21 to drive the triangular top frame 15 to move up, so as to push the squeezing rollers 27 on both sides away from each other and tighten the blended yarn. The setting of the gear set 21 can adjust the transmission ratio, so that when the cam 13 drives the slide plate 17 to slide up and down with a small amplitude, the transmission ratio can be adjusted through the setting of the gear set 21 to allow the triangular top frame 15 to slide up and down with a large amplitude.

[0045] Further, the support frame 8 is connected to a slide frame 22, and the inner wall of the slide frame 22 is connected to a guide slide bar 30, and the slide blocks 23 are symmetrically slidably connected on both sides of the slide frame 22, and the slide blocks 23 are slidably sleeved on the outer side of the guide slide bar 30, and the outer side of the guide slide bar 30 is sleeved with a spring 24, and the two ends of the spring 24 are respectively connected to the inner wall of the slide frame 22 and the slide block 23, as shown in FIG. Figure 4 As shown, under the action of the spring 24, the sliders 23 on both sides will move closer to each other;

[0046] The slider 23 penetrates the slide frame 22 and extends on both sides thereof, and is connected to a guide slide rod 25 on one side and a roller 29 on the other side. The roller 29 is fitted with a triangular top frame 15. The outer sliding sleeve of the guide slide rod 25 is provided with a mounting seat 26. Both ends of the squeezing roller 27 are rotatably connected to the mounting seat 26. The outer sleeve of the guide slide rod 25 is provided with a spring 28, and the two ends of the spring 28 are respectively connected to the slider 23 and the mounting seat 26. Figure 3 and 4 As shown, when the triangular top frame 15 moves upward, it will push the sliders 23 on both sides to overcome the elastic force of the spring two 24 through the cooperation with the roller 29, slide away from each other, and drive the squeezing rollers 27 rotatably connected between the front and rear sliders 23 on the same left and right sides through the mounting seat 26 to move away from each other. Since the mounting seat 26 is also slidably mounted on the outside of the guide slide rod four 25 and is acted upon by the spring three 28, it can have a certain buffer when the squeezing rollers 27 on both sides move away from each other to tighten the blended yarn, thereby preventing the squeezing rollers 27 from over-tightening the blended yarn and causing the blended screen yarn to break.

[0047] Further, the stirring assembly includes a turntable 31 and a guide slide bar 5 34. The turntable 31 is rotatably connected to the bottom of the dyeing box 1, and a plurality of stirring rods 32 are connected to the upper end of the turntable 31 in an array. A coaxial gear 2 33 is connected to the lower end of the turntable 31. The guide slide bar 5 34 is connected to the side wall of the dyeing box 1. A push plate 35 is slidably connected to the guide slide bar 5 34. A rotating plate 36 is rotatably connected between the push plate 35 and the slide plate 17 on each side. The push plate 35 is connected to a rack 37 meshing with the gear 2 33. Figure 6As shown, when the slide plate 17 is driven to move up and down, it can also pull the push plate 35 and the rack three 37 to slide back and forth through the rotating plate 36, and through the meshing connection between the rack three 37 and the gear two 33, drive the turntable 31 and the stirring rod 32 thereon to rotate repeatedly, stir the dye liquid in the dyeing box 1, and further improve the uniformity of the blended yarn dyeing.

[0048] Among them, the telescopic member 1 2 and the telescopic member 2 4 can both be used with existing electric cylinders, electric telescopic rods, and electric hydraulic cylinders.

[0049] Embodiment 2:

[0050] See also Figure 1-6 The present invention provides a technical solution: a blended yarn dyeing method, the specific steps include:

[0051] Step 1: Control the extension of the telescopic member 2 4 to lift the support frame 8 to the top of the dyeing box 1, and loosely wind the blended yarn around the upper and lower side rollers 9 and the outer sides of the squeezing rollers 27 on both sides of the rollers 9;

[0052] Step 2: Control the second telescopic member 4 to contract, so that the blended yarn on the outer side of the support frame 8 and the rotating roller 9 and the squeezing roller 27 falls back into the dyeing box 1, and is immersed in the dyeing liquid in the dyeing box 1 for dyeing;

[0053] Step 3: The cam 13 on the lower rotating roller 9 that falls back cooperates with the slide plate 17, so that the slide plate 17 slides up and down, and drives the triangular top frame 15 to slide up and down through the gear linkage assembly. The triangular top frame 15 drives the squeezing rollers 27 on both sides to move away from or close to each other, and repeatedly tightens the blended yarn outside the squeezing roller 27;

[0054] Step 4: While the slide plate 17 slides up and down, the stirring component is controlled to operate to stir the dye solution in the dyeing box 1.
