Description

Technical Field

[0001] This application relates to the field of printing and dyeing technology, and more specifically, to a printing and dyeing equipment and a printing and dyeing method. Background Technology

[0002] Yarn is a textile product made from various textile fibers processed to a certain fineness, used for weaving, rope making, thread making, knitting, and embroidery. Yarn dyeing involves immersing textile yarn in dyes before it is woven into fabric, thus coloring the yarn. Fabric woven from dyed yarn has a brighter color and more complete dyeing than fabric woven directly from yarn.

[0003] Current yarn dyeing methods typically involve directly immersing the yarn in the dye bath. After dyeing, the yarn is removed from the bath, causing the dye to be carried away, resulting in a decrease in the dye concentration. To address this, the equipment is usually stopped, dye is added back into the bath, and the dye and dye solution are mixed thoroughly to the desired concentration before restarting the equipment for yarn dyeing. This process significantly impacts work efficiency and therefore requires improvement. Summary of the Invention

[0008] Furthermore, the first trigger includes a mounting box, which has a mounting cavity, and a rotatable shaft is provided inside the mounting cavity; The first trigger also includes a first guide wheel and a second guide wheel mounted on the frame. The plug core is provided with a sliding rod extending through the upper end of the liquid filling cylinder. The sliding rod is provided with a traction rope that passes through the first guide wheel and the second guide wheel in sequence and is connected to the rotating shaft. The rotation of the rotating shaft drives the traction rope to pull the plug core up and down.

[0009] Furthermore, the first triggering component also includes a second sleeve fitted around the spindle, and the second sleeve is provided with a mounting rod that penetrates the frame, and the through end of the mounting rod is threaded with a nut; The rotating shaft is equipped with a gear, and the mounting cavity is equipped with a telescopic component that can be raised and lowered and extends through the mounting box.

Detailed Implementation

[0027] To further understand the content of this application, a detailed description of this application will be provided in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are merely illustrative and not intended to limit the scope of this application.

[0028] The following is in conjunction with the appendix Figures 1-9 This embodiment will be described in further detail.

[0029] like Figure 1 and Figure 2As shown, a dyeing and printing device in this embodiment includes a tank and a frame 100. The tank includes an inner tank 120 and an outer tank 110. The inner tank 120 is cylindrical and has a dyeing chamber 121 with an opening at the top. The dyeing chamber 121 contains dye liquor for dyeing yarn. The outer tank 110 is coaxially arranged with the inner tank 120 to form a ring-shaped mixing chamber 111. The mixing chamber 111 temporarily stores dye stock solution. The dye stock solution is added quantitatively to the dyeing chamber 121 to ensure that the concentration of the dye liquor in the dyeing chamber 121 is within the required concentration range for subsequent yarn dyeing. The frame 100 is located at the opening of the dyeing chamber 121. The printing and dyeing chamber 121 is provided with a partition 200, which is used to divide the printing and dyeing chamber 121 into an upper chamber 121a and a lower chamber 121b. A mesh is embedded in the partition 200 to achieve communication between the upper chamber 121a and the lower chamber 121b. The upper chamber 121a is provided with a printing and dyeing mechanism, and the lower chamber 121b is provided with a stirring component for stirring the flow of dye liquor in the printing and dyeing chamber 121. The dyeing and printing mechanism includes a rotatable main shaft 130 and a hanging frame 131 sleeved on the main shaft 130. The hanging frame 131 is used to suspend the yarn and can be raised, lowered and rotated along the main shaft 130. The mixing chamber 111 is equipped with a stirring component, which is used to stir the dye stock solution in the mixing chamber 111 to prevent the dye stock solution from precipitating, which would cause uneven concentration of the dye stock solution subsequently added to the dyeing chamber 121 and affect the concentration of the dye solution in the dyeing chamber 121. It also includes a liquid adding mechanism, which is used to quantitatively add the dye stock solution in the mixing chamber 111 into the printing and dyeing chamber 121. The liquid adding mechanism includes a liquid adding component and a pumping component. The frame 100 is provided with a first trigger and a second trigger. When the hanger 131 moves upward along the main shaft 130, the first trigger and the second trigger are triggered in sequence. The first trigger is used to drive the liquid adding component to add dye stock solution into the printing and dyeing chamber 121, and the second trigger is used to add dye stock solution into the liquid adding component.

[0030] In this embodiment, the main shaft 130 is vertically arranged in the dyeing and printing chamber 121, and its upper and lower ends are respectively rotatably mounted on the frame 100 and the bottom wall of the dyeing and printing chamber 121 through bearings. In actual use, the yarn is looped and suspended on the hanger 131 and fixed to achieve the suspension and fixation of the yarn on the hanger 131. At this time, the hanger 131 descends along the main shaft 130 into the upper cavity 121a so that the yarn can be immersed in the dye solution in the dyeing chamber 121. During this process, the hanger 131 can drive the yarn loop on it to rotate slowly, so that the yarn can fully contact the dye solution at different positions in the upper cavity 121a and avoid uneven dyeing of the yarn. When the hanger 131 rises along the main shaft 130, it can drive the yarn loop to be discharged from the upper cavity so that the yarn loop after dyeing can be removed and the yarn loop to be dyed can be placed so that the equipment can continue to perform yarn dyeing operations.

[0031] When the yarn is dyed, the concentration of the dye solution in the dyeing chamber 121 will decrease. In order to ensure that the concentration of the dye solution in the dyeing chamber is within the required range, in this embodiment, the dye stock solution in the mixing chamber 111 is quantitatively added to the dyeing chamber 121 by the liquid adding mechanism, and the dye is made to flow between the upper chamber 121a and the lower chamber 121b by the agitation component, so that the dye stock solution is fully mixed in the dye solution, thereby ensuring that the dye solution concentration in the dyeing chamber 121 is uniform and improving the uniformity of yarn dyeing.

[0032] In order to achieve quantitative addition of dye stock solution into the dyeing chamber 121, this embodiment uses the above-described structure so that when the hanger 131 drives the yarn loop to be completely discharged from the upper chamber 121a, it continues to move upward along the main shaft 130, which first triggers the first triggering element, thereby adding the dye stock solution in the liquid adding element into the dyeing chamber 121. At this time, the hanger 131 continues to move upward along the main shaft 130, which triggers the second triggering element, enabling the pumping element to add the dye stock solution in the mixing chamber 111 into the liquid adding element, so that it can add the dye stock solution into the dyeing chamber 121 again.

[0033] Combination Figure 3 As shown, in this embodiment, a cavity is provided inside the spindle 130 along its extension direction, and the cavity is open at both ends. A limiting groove communicating with the cavity is provided on the outer side wall of the spindle 130 along its extension direction. The hanger 131 includes a first sleeve 310 sleeved outside the main shaft 130 and a turntable 320 disposed in the cavity. Multiple hanging rods 311 are evenly distributed on the outer side wall of the first sleeve 310. The turntable 320 and the first sleeve 310 are connected by a limiting block that slides through the corresponding limiting groove. A lead screw 210 that penetrates the cavity is fixed between the frame 100 and the bottom wall of the printing and dyeing cavity 121. The lead screw 210 is threaded through the turntable 320.

[0034] In this embodiment, the hanging rod 311 is used to suspend and fix the yarn coil; through the cooperation of the limiting block and the limiting groove, the main shaft 130 can slowly rotate to drive the first sleeve 310, the turntable 320 and the hanging rod 311 to rotate. At the same time, since the lead screw 210 is fixed and the thread passes through the turntable 320, the rotation of the turntable 320 can move up and down along the lead screw 210, thereby driving the hanging bracket 131 to move up and down along the main shaft 130.

[0035] In order to achieve the rotation of the main shaft 130, in this embodiment, a first sprocket is fixedly provided at the upper end of the main shaft 130, a first reduction motor 101 is provided on the frame 100, a second sprocket is provided on the output shaft of the first reduction motor 101, and a chain is sleeved between the first sprocket and the second sprocket to achieve the main shaft 130 to slowly rotate in both directions.

[0036] Combination Figure 4 As shown, in this embodiment, the liquid filling component is vertically installed on the side wall of the frame 100. The liquid filling component includes a liquid filling cylinder 330, a liquid filling chamber 411 is provided inside the liquid filling cylinder 330, a liquid filling pipe 331 communicating with the liquid filling chamber 411 is provided at the bottom of the liquid filling cylinder 330, a guide surface 412 is provided on the bottom wall of the liquid filling chamber 411, a plug core 430 is provided inside the liquid filling chamber 411 through a first spring 420 and abuts against the guide surface 412, and an annular groove 431 is provided on the plug core 430. The first spring 420 pushes the plug core 430 to fit against the guide surface 412 so that the liquid filling pipe 331 is closed. A first trigger is used to drive the plug core 430 to rise and fall to realize the opening and closing of the liquid filling pipe 331.

[0037] In this embodiment, the plug core 430 is slidably installed in the liquid filling chamber 411. The upper end of the first spring 420 abuts against the upper end of the liquid filling chamber 411, and the lower end abuts against the plug core 430, so as to push the plug core 430 to fit against the guide plate surface 412, thereby closing the annular groove 431 and the liquid filling tube 331. The first trigger is used to drive the plug core 430 to rise and fall to open and close the liquid filling tube 331, so as to realize the quantitative addition of dye stock solution in the liquid filling chamber 411 to the dyeing chamber 121.

[0038] Combination Figures 5-7 As shown, in this embodiment, the first trigger includes a mounting box 340. Specifically, the upper end of the mounting box 340 extends upward to form a mounting folding plate 601. The mounting folding plate 601 is fixed to the frame 100 by screws. The mounting box 340 is provided with a mounting cavity, and a rotatable rotating shaft 510 is provided in the mounting cavity. The first trigger also includes a first guide wheel 301 and a second guide wheel 302 mounted on the frame 100. The plug core 430 is provided with a sliding rod 432 extending through the upper end of the liquid filling cylinder 330. The sliding rod 432 is slidably mounted through the upper end of the liquid filling cylinder 330. The sliding rod 432 is provided with a traction rope 332 that passes through the first guide wheel 301 and the second guide wheel 302 in sequence and is connected to the rotating shaft 510. The rotation of the rotating shaft 510 drives the traction rope 332 to pull the plug core 430 up and down.

[0039] In actual use, one end of the traction rope 332 is connected to the extended end of the sliding rod 432, and the other end is connected to the rotating shaft 510. In the initial state, the first spring 420 pushes the plug core 430 to fit against the guide plate surface 412. At this time, the traction rope 332 can be wound on the rotating shaft 510 by rotating forward and backward, thereby pulling the plug core 430 up and down in the liquid filling chamber 411 to realize the opening and closing of the liquid filling pipe 331.

[0040] In this embodiment, the first triggering component also includes a second sleeve 350 sleeved outside the main shaft 130. The second sleeve 350 is provided with a mounting rod 351 that penetrates the frame 100. The through end of the mounting rod 351 is threaded with a nut, thereby realizing the hoisting of the second sleeve 350 on the frame 100. A gear 511 is provided on the rotating shaft 510. A telescopic component that can be raised and lowered and extends through the mounting box 340 is provided in the mounting cavity. A rack 520 that meshes with the gear 511 is provided on the rear side of the telescopic component. A lever 352 for moving the telescopic component upward is provided on the outer wall of the second sleeve 350. A guide block 530 for driving the telescopic component to retract is provided on the outer wall of the mounting box 340.

[0041] With the above structure, the hanger 131 rises along the main shaft 130, which lifts the second sleeve 350 along the main shaft 130. This drives the lever 352 to push the telescopic component to rise in the mounting cavity, thereby driving the rack 520 to move upward, driving the gear 511 to drive the rotating shaft 510 to rotate, and then pulling the plug core 430 upward through the traction rope 332, so as to realize the addition of the dye stock solution in the liquid filling chamber 411 into the printing and dyeing chamber 121. The guide block 530 is designed so that when the second sleeve 350 rises along the main shaft 130 during actual use, it drives the telescopic component to move upward until it engages with the guide block 530. At this time, the telescopic component retracts to avoid the lever 352, allowing the bracket 131 to drive the second sleeve 350 to continue moving upward along the main shaft 130, so as to trigger the second triggering component. When the lever 352 disengages from the telescopic component, the telescopic component resets under its own weight and the action of the first spring 420, thereby driving the rotating shaft 510 to rotate so that the plug core 430 fits against the guide surface 412, thus closing the liquid filling cylinder 330, so that the subsequent pumping component can pump dye stock into it. At the same time, the telescopic component descends to its initial position.

[0042] In this embodiment, the telescopic component includes a telescopic box 540 with a telescopic cavity inside. A telescopic block 560 with one end protruding is provided inside the telescopic cavity via a second spring 550. The upper side of the telescopic block 560 is provided with a first inclined surface 561, and the lower end of the guide block 530 is provided with a second inclined surface 531 that is pressed against the first inclined surface 561.

[0043] Specifically, a sliding groove 501 is provided on the opposite side wall of the mounting cavity along its height direction, and a slider is provided on the side wall of the telescopic box 540 that slides within the sliding groove 501, thereby realizing the lifting and lowering installation of the telescopic box 540 within the mounting cavity. The telescopic cavity has an opening at one end, and the rack 520 is installed at the opening of the telescopic cavity to realize the assembly of the second spring 550 and the telescopic block 560 in the telescopic cavity; specifically, the other end of the telescopic cavity has a notch for the telescopic block 560 to extend out, and the end of the telescopic block 560 located in the telescopic cavity has a stop extending outward to prevent the second spring 550 from pushing the telescopic block 560 out of the telescopic cavity. Specifically, by setting the first inclined surface 561 and the second inclined surface 531, when the telescopic member moves upward in the mounting cavity, the first inclined surface 561 presses against the second inclined surface 531, so that the telescopic block 560 retracts into the telescopic cavity to avoid the lever block 352; at the same time, when the lever block 352 descends along the main shaft 130, the lever block 352 can press against the first inclined surface 561 to make the telescopic block 560 retract into the telescopic cavity to avoid the lever block 352, so that the second sleeve 350 can be reset, so that the subsequent upward movement of the bracket 131 can trigger the second trigger assembly to drive the opening and closing of the liquid filling component; In order to reset the second sleeve 350, a third spring (not shown in the figure) is sleeved on the mounting rod 351 to push the second sleeve 350 downward.

[0044] In this embodiment, the pumping component includes a delivery pump 140, which is installed on the top wall of the mixing chamber 111. The delivery pump 140 is used to input the dye stock solution in the mixing chamber 111 into the liquid addition chamber 411 through the delivery pipe 141.

[0045] In this embodiment, the second triggering element includes a first triggering switch 610 located above the guide block 530. When the telescopic member avoids the toggle block 352, so that the toggle block 352 continues to move upward along the main shaft 130, the first triggering switch 610 is triggered to enable the delivery pump 140 to work once. Thus, when the liquid filling chamber 411 is closed, the delivery pump 140 can be used to input the dye stock solution in the mixing chamber 111 into the liquid filling chamber 411.

[0046] In this embodiment, a second trigger switch (not shown in the figure) is provided at the bottom of the second sleeve 350. When the first sleeve 310 moves upward and contacts the second sleeve 350, the second trigger switch is triggered. The second trigger switch is used to enable the stirring component and the agitation component to work simultaneously.

[0047] In this embodiment, the outer tank 110 has a liquid inlet hole on its side wall that connects to the mixing chamber 111, thereby allowing the dye stock solution to be added into the mixing chamber 111.

[0048] In this embodiment, combined with Figure 8 and Figure 9 As shown, the agitation assembly includes several first rotating rods 220 rotatably disposed in the lower cavity 121b. The first rotating rods 220 are provided with fan blades 221. The several first rotating rods 220 are evenly distributed around the main shaft 130. When the first rotating rods 220 rotate, they drive the fan blades 221 to rotate, thereby driving the flow of dye liquor in the lower cavity 121b and the upper cavity 121a to generate turbulence, which facilitates the full mixing of the dye stock solution in the dye liquor.

[0049] The stirring assembly includes several second rotating rods 230 rotatably disposed in the mixing chamber 111. The second rotating rods 230 are provided with spiral stirring blades 231. The several second rotating rods 230 are evenly distributed around the circumference of the mixing chamber 111. When the second rotating rods 230 drive the spiral stirring blades 231 to rotate, the dye stock solution in the mixing chamber 111 can be stirred and mixed to prevent precipitation.

[0050] Specifically, the lower end of the first rotating rod 220 extends through the bottom wall of the tank and is fixedly installed with a first synchronous wheel 810. The lower end of the second rotating rod 230 extends through the bottom wall of the tank and is fixedly installed with a second synchronous wheel 820. In actual use, a first synchronous belt 801 is sleeved between the first synchronous wheel 810 and the corresponding second synchronous wheel 820, and a second synchronous belt 802 is sleeved between adjacent second synchronous wheels 820. The top of the outer tank 110 is provided with a second reduction motor 102, which is used to drive one of the several second rotating rods 230 to rotate, thereby driving the first rotating rod 220 and the second rotating rod 230 to rotate, thus realizing the operation of the stirring component and the agitation component.

[0051] Specifically, by setting the second trigger switch, when the hanger 131 drives the yarn coil to disengage from the upper cavity 121a, the hanger 131 can push the second sleeve 350 to start moving upward, thereby triggering the second trigger switch to make the agitation component and the stirring component work. That is, the agitation component and the stirring component can be made to work before the liquid addition mechanism works. At the same time, when the hanger 131 brings the yarn into the upper cavity 121a, it can drive the agitation component and the stirring component to stop working, so as to avoid the waste of electrical energy caused by the continuous operation of the agitation component and the stirring component during the yarn dyeing process.

[0052] The present invention also provides a dyeing and printing method, which uses the above-mentioned dyeing and printing equipment and specifically includes the following steps: S1. The mixing chamber 111 contains dye stock solution, and the printing and dyeing chamber 121 contains dye solution. The drive bracket 131 is moved to the main shaft 130 below the second sleeve 350. The yarn is wrapped around and attached to the hanging rod 311 and fixed. The rotation of the main shaft 130 drives the bracket 131 to descend and rotate so that the yarn is immersed in the dye solution. S2. After the yarn printing and dyeing is completed, the main shaft 130 rotates to drive the hanging frame 131 to rise until the hanging frame 131 moves to the uppermost end of the main shaft 130. During this process, the hanging frame 131 first triggers the second trigger switch to make the stirring component and the agitation component work. Then it triggers the first trigger to add the dye stock solution in the liquid adding component into the printing and dyeing chamber 121. Then it triggers the second trigger to make the pumping component pump the dye stock solution in the mixing chamber 111 into the liquid adding component. S3. When the hanger 131 moves to the uppermost end of the main shaft 130, remove the yarn loop on the hanging rod 311 and place the yarn to be dyed on it.
