[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] An embodiment of a dyeing device for textile cotton thread of the present invention is as follows Figures 1 to 7 shown.

[0028] A dyeing device for textile cotton thread includes a housing 100, a pay-off roller 170, a take-up roller 180, a squeezing mechanism 200, an adjusting mechanism 400, and a winding mechanism 300. The housing 100 is a rectangular shell arranged in the horizontal direction, and a dye box 150 is arranged inside the housing 100. The dye box 150 is arranged in the horizontal direction and located at the lower side of the housing 100, and the dye box 150 is filled with dye liquid. Specifically, two box plates 151 are arranged inside the housing 100, and the two box plates 151 are arranged in the vertical direction, and the dye box 150 is defined between the two box plates 151.

[0029] The winding mechanism 300 includes a rotating shaft 310, a sliding hinge plate 340, a fixed hinge plate 313 and a plurality of adjustment components. The rotating shaft 310 is installed in the housing 100 so as to be rotatable around its own axis and around one end thereof, and the rotating shaft 310 is arranged to be tilted.

[0030] The sliding hinge plate 340 can slide along the axial direction of the rotating shaft 310 and rotate with the rotating shaft 310. Specifically, the rotating shaft 310 is provided with an axial groove 311 extending along its axial direction. A protrusion is provided at the inner end of the sliding hinge plate 340, and the protrusion is slidably installed in the axial groove 311, so that the sliding hinge plate 340 can slide along the axial direction of the rotating shaft 310 and rotate with the rotating shaft 310.

[0031] The fixed hinge plate 313 is fixedly mounted on the rotating shaft 310, the diameter of the sliding hinge plate 340 is larger than the diameter of the fixed hinge plate 313, the adjustment assembly includes a support rod 320 and a connecting rod 330, the connecting rod 330 is arranged one by one with the support rod 320, the length of the support rod 320 is larger than the connecting rod 330, one end of the plurality of connecting rods 330 is evenly distributed in the circumferential direction of the sliding hinge plate 340, and one end of the connecting rod 330 is rotatably mounted on the sliding hinge plate 340; the plurality of connecting rods 330 The other end is rotatably connected to one end of a plurality of struts 320, and the plurality of struts 320 are evenly distributed in the circumferential direction of the fixed hinge plate 313, and the other end of the struts 320 is rotatably installed on the fixed hinge plate 313, and the plurality of struts 320 form a cone, and the end of the struts 320 connected to the connecting rod 330 is the large end; when the sliding hinge plate 340 slides in the shaft groove 311, the connecting rod 330 drives the struts 320 to rotate around the fixed hinge plate 313.

[0032] The cone is arranged on the upper side of the dye box 150, and at least half of the cone is submerged in the dye solution. The pay-off roller 170 and the take-up roller 180 are both installed in the housing 100. Specifically, two brackets are arranged in the housing 100, each bracket includes two support plates 120, and each support plate 120 is provided with a limiting hole 121. Both ends of the pay-off roller 170 and the take-up roller 180 are provided with mounting posts, and the two mounting posts are respectively arranged in the two limiting holes 121.

[0033] The pay-off roller 170 and the take-up roller 180 are both arranged on the upper side of the dye box 150, and the pay-off roller 170 is located on the side of the take-up roller 180 close to the sliding hinge plate 340. In the initial state, the cotton thread on the pay-off roller 170 is wound around the cone and then connected to the take-up roller 180. The take-up roller 180 is rotatably arranged. When the take-up roller 180 rotates, the cotton thread wound around the cone is pulled to rotate the winding mechanism 300, thereby driving the pay-off roller 170 to rotate and pay the thread, and the cotton thread is dyed during the rotation. Specifically, the take-up roller 180 is driven to rotate by the motor 190, and a mounting plate 122 is arranged in the housing 100. The mounting plate 122 is fixed to the support plate 120 on which the take-up roller 180 is installed. The motor 190 is installed on the mounting plate 122, and the take-up roller 180 is driven to rotate when the motor 190 rotates. The squeezing mechanism 200 can squeeze the cotton thread when the cotton thread is immersed in the dye solution; the adjusting mechanism 400 can drive the rotating shaft 310 to rotate around the end close to the fixed hinge plate in the initial state, so that the cone changes the taper.

[0034] In this embodiment, a pay-off roller 170, a take-up roller 180, a squeezing mechanism 200, an adjusting mechanism 400 and a winding mechanism 300 are arranged. When the take-up roller 180 rotates, the cotton thread wound on the cone is pulled to rotate the winding mechanism 300, that is, the cone formed by the plurality of support rods 320 rotates, thereby driving the pay-off roller 170 to pay off the thread. The rotation of the cone enables the cotton thread on the entire cone to be continuously immersed in the dye solution during the rotation process, thereby ensuring the complete immersion of the cotton thread, and the squeezing mechanism 200 will also squeeze the cotton thread when the cotton thread is immersed in the dye solution. Due to the effect of the cone structure, the cotton thread will be tightened when it is driven by the reciprocating movement of the slider 260 to move toward the large end of the cone (the end close to the sliding hinge plate 340). The cotton thread moves on the cone surface, and the cone surface gives the cotton thread a friction force along the cone surface. This friction force causes the cotton thread to twist circumferentially around its own axis. The twisting makes the cotton thread further tightened. The twisting of the cotton thread itself can also squeeze out the dye. The dyeing effect is improved by continuous immersion and extrusion. The design of the cone structure further ensures uniform dyeing and improves the dyeing effect.

[0035] In this embodiment, the extrusion mechanism 200 includes a left ring 210, an upper support rod 230, a lower support rod 240, a right ring 220, a first electric cylinder 280, a limit assembly and a plurality of sliders 260; the left ring 210 and the right ring 220 are both circular ring structures, the diameter of the left ring 210 is larger than the diameter of the right ring 220, the sliding hinge plate 340 is installed on the inner end of the left ring 210, a left ring groove 211 is opened at the inner end of the left ring 210, the left ring 210 is installed on the sliding hinge plate 340 through the left ring groove 211, the sliding hinge plate 340 can rotate relative to the left ring 210, and can move synchronously with the left ring 210, the fixed hinge plate 313 is installed on the inner end of the right ring 220, a right ring groove 221 is opened at the inner end of the right ring 220, the right ring 220 is installed on the fixed hinge plate 313 through the right ring groove 221, and the fixed hinge plate 313 can rotate relative to the right ring 220.

[0036] The left ring 210 is rotatably connected to one end of the upper support rod 230 and one end of the lower support rod 240 through the connecting rod 250, and the left ring 210 and the connecting rod 250 are arranged to be rotatably connected; the other end of the upper support rod 230 and the other end of the lower support rod 240 are rotatably connected to the right ring 220 respectively, and the limit assembly can keep the lower support rod 240 always in a horizontal state and can move in the vertical direction; a plurality of sliders 260 are arranged on the upper support rod 230 in sequence and at equal distances, and the sliders 260 are arranged on the upper support rod 230 in sequence and at equal distances. 0 is slidably mounted on the upper support rod 230, each slider 260 is provided with a winding hole 261, and the winding hole 261 is arranged toward the dye box 150, a spring 270 is arranged between every two adjacent sliders 260, and the first electric cylinder 280 is fixedly mounted on the end of the upper support rod 230 close to the sliding hinge plate, and the first electric cylinder 280 is used to drive the slider 260 to move. In the initial state, the cotton thread on the pay-off roller 170 passes through the winding hole 261 (closest to the end of the first electric cylinder 280) Figure 3 The cotton thread 260 is wound around the cone formed by the plurality of support rods 320, and then passes through another adjacent winding hole 261, until it passes through all the winding holes 261, and then comes out from the last winding hole 261 and is wound around the take-up roller 180, thereby completing the winding of the cotton thread to be dyed.

[0037] In this embodiment, the limiting assembly includes a limiting column 160 and a limiting block 290. The limiting column 160 is arranged in the dye box 150 along the vertical direction. A second slide groove 161 is opened on the limiting column 160. The second slide groove 161 is arranged along the vertical direction. The limiting block 290 is slidably installed on the lower support rod 240 along the horizontal direction and slidably installed on the second slide groove 161 along the vertical direction, so that the lower support rod 240 maintains a horizontal state and can move in the vertical direction.

[0038] In this embodiment, the adjustment mechanism 400 includes a left support frame 410 and a right support frame 420; the left support frame 410 is arranged perpendicular to the horizontal direction, and adjustment blocks 440 are arranged at both ends of the left support frame 410, and the adjustment blocks 440 can be slidably installed in the housing 100 along the vertical direction; the right support frame 420 is arranged perpendicular to the horizontal direction, and the right support frame 420 is rotatably installed in the housing 100. Specifically, a rotating hole 130 is opened in the housing 100, and both ends of the right support frame 420 are rotatably installed in the rotating hole 130. One end of the rotating shaft 310 can slide in the left support frame 410 and can rotate around its own axis direction in the left support frame 410, and the other end of the rotating shaft 310 can rotate around the right support frame 420, and the right support frame 420 is located in the dye box 150.

[0039] Furthermore, the adjustment mechanism 400 further includes a second electric cylinder 430 , which is fixedly installed in the housing 100 and disposed at the lower end of the adjustment block 440 , and is used to drive the adjustment block 440 to slide in the vertical direction. Specifically, a first slide groove 140 is provided in the housing 100 and is arranged in the vertical direction. The first slide groove 140 is located outside the dye box 150 and is arranged near the upper side of the dye box 150. The lower end of the second electric cylinder 430 is fixed to the bottom of the first slide groove 140. The adjustment block 440 is slidably installed in the first slide groove 140 and is installed at the output end of the second electric cylinder 430, so that the second electric cylinder 430 can drive the adjustment block 440 to slide up and down in the first slide groove 140, thereby changing the inclination of the rotating shaft 310, so that the rotating shaft 310 rotates around the right support frame 420. When the rotating shaft 310 rotates, due to the limiting effect of the left support frame 410, the rotating shaft 310 will be prompted to slide inside the left support frame 410. Then, the sliding hinge plate 340 slides in the shaft slide groove 311, and the support rod 320 is driven to contract through the connecting rod 330, thereby changing the taper of the cone.

[0040] In this embodiment, by setting a left support frame 410 and a right support frame 420, when it is necessary to dye cotton threads of different thicknesses, when the thickness of the cotton threads is greater than a preset value (the preset value is when the second electric cylinder 430 is at the lowest point), the second electric cylinder 430 drives the adjustment block 440 to move upward, so that the rotating shaft 310 slides relative to the left support frame 410 toward the side close to the right support frame 420, thereby pushing the sliding hinge plate 340 to move in the shaft slide groove 311, and then pushing the support rod 320 to open through the connecting rod 330, so that the taper of the cone becomes larger. By changing the taper of the cone, the cotton thread will be tightened when it is driven by the slider 260 to move toward the large cone surface, that is, when it moves to the left, and the amount of twisting of the cotton thread becomes larger when twisting, thereby ensuring that uniform dyeing can be achieved for cotton threads of different thicknesses.

[0041] In combination with the above embodiments, the specific working principle and working process of the present invention are as follows: before dyeing the cotton thread, the cotton thread on the pay-off roller 170 is first passed through the winding hole 261 ( Figure 3 The cotton thread is wound around the plurality of support rods 320 to form a cone, and then passes through another adjacent winding hole 261. The above process is repeated until it passes through all the winding holes 261, comes out from the last winding hole 261 and is wound around the take-up roller 180, thereby completing the winding of the cotton thread to be dyed.

[0042] The dye box 150 contains dye liquid, the right support frame 420 is located in the dye box 150, and the left support frame 410 is arranged near the upper side of the dye box 150, and the cone with cotton thread wrapped around half of the dye liquid. The setting of the limit column 160 keeps the lower support rod 240 in a horizontal state.

[0043] Then the cotton thread begins to be dyed, and the first electric cylinder 280 is started. The first electric cylinder 280 reciprocates, and the multiple sliders 260 are driven to reciprocate on the upper support rod 230 through the action of the first electric cylinder 280 and the spring 270, that is, the multiple sliders 260 keep approaching and moving away from each other, so that the cotton thread on the winding hole 261 corresponding to each slider 260 is also continuously reciprocated and stretched. Then the motor 190 is started to make the cotton thread pass through the take-up roller 180 and continue to be transmitted to the drying mechanism (the drying mechanism is the existing technology and will not be repeated here). The dried cotton thread will be finally wound up.

[0044] When the motor 190 drives the take-up roller 180 to rotate, it will pull the cotton thread wound on the cone, causing the winding mechanism 300 to rotate, even if the cone formed by multiple support rods 320 rotates, and then drive the pay-off roller 170 to pay off the thread. The rotation of the cone causes the cotton thread on the entire cone to be continuously immersed in the dye solution during the rotation process, ensuring the complete immersion of the cotton thread, and the first electric cylinder 280 also drives the cotton thread to continuously reciprocate and contract in the axial direction of the rotating shaft 310 through the slider 260. Due to the effect of the cone structure, the cotton thread is driven by the reciprocating movement of the slider 260 to move toward the large end of the cone (the end close to the sliding hinge plate 340), that is, when it moves to the left, the cotton thread will be tightened, and the cotton thread moves on the cone surface. The cone surface gives the cotton thread a friction force along the cone surface direction. This friction force causes the cotton thread to twist circumferentially around the axis of the cotton thread itself, and the twisting makes the cotton thread further tightened. The cotton thread twists itself to squeeze out the dye, and the dyeing effect is improved through continuous immersion and extrusion. The cone structure design further ensures uniform dyeing and improves the dyeing effect.

[0045] Before use, the present invention can drive the second electric cylinder 430 to drive the adjustment block 440 to move in the first slide groove 140 according to the thickness of the cotton thread, thereby changing the inclination of the rotating shaft 310. When the rotating shaft 310 rotates, due to the limiting effect of the left support frame 410, the rotating shaft 310 will be prompted to slide in the left support frame 410. Then the sliding hinge plate 340 slides in the shaft slide groove 311, and the support rod 320 is driven to shrink through the connecting rod 330 to change the taper of the cone. Specifically, when the thickness of the cotton thread is greater than the preset value (the preset value is when the second electric cylinder 430 is at the lowest point), the second electric cylinder 430 drives the adjustment block 440 to move upward, so that the rotating shaft 310 slides relative to the left support frame 410 to the side close to the right support frame 420, thereby pushing the sliding hinge plate 340 to move in the shaft slide groove 311, and then pushing the support rod 320 to open through the connecting rod 330, so that the taper of the cone becomes larger. By changing the taper of the cone, the cotton thread is tightened when it is driven by the slider 260 to move toward the large cone surface, and the amount of twisting of the cotton thread becomes larger, ensuring that cotton threads of different thicknesses can be dyed uniformly. The reciprocating stroke of the first electric cylinder 280 can also be adjusted to change the shrinkage of the cotton thread to meet the dyeing requirements of cotton threads of different thicknesses.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
