Description

Technical Field

[0001] The invention belongs to the technical field of fabric processing, and in particular relates to an autonomous dye supply device and a uniform feeding method for denim indigo foam dyeing. Background Art

[0002] Foam dyeing is a low-liquid dyeing process that uses a foaming machine to fill the dyeing liquid with a certain proportion of air or nitrogen to make a foam system, and then applies the foam to the fabric or yarn. The dye generally needs to be blended evenly before foaming.

[0003] In the prior art, when dyeing denim indigo foam, the dye is generally blended by mixing indigo dye, alkali agent, insurance powder, penetrant, foaming agent, stabilizer and water in a certain proportion to obtain a solution of a certain concentration, which is then transported to a foam generator to generate foam with a certain foam ratio, and then applied to the yarn in a continuous manner through an applicator. The conventional dye mixing method is to weigh each component in proportion and stir and mix them. In this process, on the one hand, it is more troublesome to weigh the raw materials, and it is also necessary to ensure the formula ratio, which further increases the difficulty of the work; on the other hand, due to the speed limit of the pulping and dyeing machine, the dyeing process often lasts for more than several hours. The foaming agent in the dye solution is in contact with the alkali agent and insurance powder for a long time, which will reduce the foaming activity and affect the stability and effect of the foaming.

[0004] Therefore, in order to solve the above problems, an autonomous dye supply device and a uniform feeding method for foam dyeing are proposed, which have good mixing effect, convenient proportion adjustment and easy use. The dye solution and the foaming system are prepared separately, evenly mixed in the autonomous dye supply device, and then sent to the foaming device, which reduces the contact time between the foaming system and the alkali solution, expands the use types of foaming agents, and ensures the foaming effect.

[0013] Preferably, there are two first transmission assemblies and two second transmission assemblies, and the two first transmission assemblies are respectively located at the front end of the left impeller and the rear end of the right impeller. The two impellers rotate in opposite directions when the material is discharged through the opening at the bottom of the fixed block to impact the rectangular plate in the impeller.

[0014] Preferably, a scale is provided in the middle of the top of the fixed block, and a square hole is provided at the connection between the top of the fixed block and the injection tube. When the baffle plate in the limiting assembly moves to the farthest point at one end inside the fixed block, the corresponding hole is closed and the hole at the other end is completely connected. The fixed block and the limiting assembly are sealed by a rubber ring.

[0015] The present invention provides the following technical solution: a method for uniformly feeding an autonomous dye for foam dyeing, wherein the method for uniformly feeding an autonomous dye for foam dyeing is:

[0016] When dyeing denim indigo foam, first press the adjustment knob toward the rear end to separate the first baffle from the inner wall of the fixed block, then turn the adjustment knob to drive the connecting tooth plate in the limit assembly to move through the matching gear, thereby changing the position of the baffle inside the fixed block. At this time, the scale value pointed to by the pointing block in the limit assembly changes, showing the area ratio of the holes at the left and right ends of the fixed block, and the area ratio of the holes represents the ratio of the flow rate. After adjustment, release the adjustment knob, and the first baffle contacts the inner wall of the fixed block under the elastic force of the spring, and the resistance of the rubber layer prevents the adjustment assembly from rotating;

[0017] Then, indigo dye, NaOH, hydrosulfite, penetrant and water are respectively injected through two injection pipes to mix into a first solution of a certain concentration and a stabilizer, foaming agent and water are mixed into a second solution of a certain concentration. Since the position of the baffle plate has been adjusted in advance, the flow rates of the first solution and the second solution passing through the left and right ends are in a specific ratio, so there is no need for manual weighing;

[0018] When the first solution and the second solution pass through the two injection pipes and the fixed block into the interior of the mixing box, the first solution and the second solution first contact the impeller, and the impeller rotates due to the impact of gravity on the rectangular plate in the impeller, while the two impellers rotate synchronously in opposite directions, and the first solution and the second solution that collide with the rectangular plate are broken and separated, and are mixed and fall in the middle of the two impellers;

[0019] When the dye solution formed by mixing the first solution and the second solution falls on the stirring component and collides with the blades at the top of the stirring component, the spiral shape of the blades can drive the stirring component as a whole to rotate through pressure, and at the same time, due to the transmission of the first transmission component and the second transmission component, the two impellers and the stirring component can rotate at the same time, and the rotation of the stirring component can stir the dye solution inside the mixing box to promote uniform mixing;

[0020] After the mixing is completed, open the valve on the discharge pipe and add the mixed dye solution in the mixing box into the foaming machine for foaming.

[0021] The beneficial effects of the present invention are as follows:

[0022] The present invention cooperates with the fixed block, the impeller, the stirring assembly and other structures. When dyeing denim indigo foam, the first solution and the second solution respectively pass through the fixed block from two injection pipes to reach the inside of the mixing box. The first solution and the second solution first contact the impeller, and the impeller rotates due to the impact of gravity on the rectangular plate in the impeller, and the two impellers rotate synchronously in opposite directions. The first solution and the second solution that collide with the rectangular plate are broken and separated, and are mixed and dropped in the middle of the two impellers. Subsequently, when the dye liquor of the first solution and the second solution falls on the stirring assembly, the stirring assembly can be driven to rotate, and the dye liquor inside the mixing box can be stirred to promote uniform mixing.

[0023] The present invention cooperates with the structures such as the fixed block, the limit assembly and the adjustment assembly, and the first solution and the second solution respectively pass through the holes at both ends of the fixed block from the two injection pipes. Since the shielding plate blocks the two holes, and the area values ​​of the two holes change when the shielding plate is moved, the first solution and the second solution respectively discharged through the two holes have the same ratio as the area values ​​of the two holes. At this time, the first solution and the second solution entering the mixing box have the same ratio, and no manual weighing is required, which is convenient to operate.

[0024] The present invention cooperates with the fixed block, the limit assembly and the adjustment assembly, and the limit assembly can be driven to move by rotating the adjustment assembly, thereby changing the area ratio between the two holes. The rubber layer on the surface of the first baffle and the spring can ensure that the adjustment assembly is stable when not rotating, thereby ensuring the use effect. The top of the fixed block is provided with a ratio value, which can be used with the pointing block to facilitate observation of the ratio between the two holes and facilitate adjustment.

[0025] In the feeding process adopted by the present invention, the mixing time of the foaming agent and the alkaline solution is short, the foaming agent does not need to be in an alkaline environment for a long time, the foaming agent will not be affected by the alkalinity to foam, and the foaming activity is improved.

DETAILED DESCRIPTION

[0034] 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.

Because the hole is square, the ratio of the discharge speeds of the two holes can be adjusted by moving the limiting component 5, and the scale value on the top of the fixed block 3 is displayed. The scale pointed by the pointing block 52 is the ratio of the discharge speeds of the two holes. In this way, when the first solution and the second solution are input and mixed, the ratio of the two can always be maintained, and it is easy to use and simple to operate. When the first solution and the second solution enter the mixing box 1 through the two holes respectively, the impeller 8 and the stirring component 11 can be driven to rotate by the impact force, and the mixture is broken and mixed under the action of the reaction force, so that the mixing effect is good.

[0036] like Figure 4 , Figure 5 As shown, the limit assembly 5 includes a shielding plate 51 movably connected to the fixed block 3, a pointing block 52 is fixedly installed at the rear end of the middle of the top of the shielding plate 51, and a connecting tooth plate 53 is fixedly installed in the middle of the bottom of the shielding plate 51. The adjustment assembly 6 includes an adjustment knob 61 movably connected to the fixed block 3, and the rear end of the outer surface of the adjustment knob 61 is fixedly installed with a first baffle 62, a matching gear 63 and a second baffle 64 from front to back. The front side of the first baffle 62 is provided with a rubber layer, and the back of the second baffle 64 is fixedly connected to the spring 7. The adjustment knob 61, the first baffle 62, the matching gear 63 , and the second baffle plate 64 can both rotate and move back and forth inside the fixed block 3; by rotating the adjusting knob 61, the first baffle plate 62, the matching gear 63 and the second baffle plate 64 can be driven to rotate, and the position of the baffle plate 51 is adjusted by the engagement of the second baffle plate 64 with the connecting tooth plate 53, so that the size of the two holes can be easily adjusted to control the flow rate. The first baffle plate 62 is provided with a rubber layer on the front side, and the elastic force of the spring 7 can make the rubber layer closely contact with the inner wall of the fixed block 3, thereby increasing the friction force and preventing the sliding of the adjusting component 6 from affecting the position of the baffle plate 51.

[0037] like Figure 6 , Figure 7 As shown, the first transmission assembly 9 includes a first transmission wheel 91, a first transmission belt 92 and a second transmission wheel 93. The first transmission wheel 91 is fixedly connected to the front end of the impeller 8, and the first transmission wheel 91 is transmission-connected to the second transmission wheel 93 through the first transmission belt 92. The first transmission wheel 91, the first transmission belt 92 and the second transmission wheel 93 are all movably installed in the side wall of the mixing box 1. The second transmission assembly 10 includes a third transmission wheel 101, a second transmission belt 102, a fourth transmission wheel 103 and a first bevel gear 104. The outer side of the third transmission wheel 101 is transmission-connected to the fourth transmission wheel 103 through the second transmission belt 102. The middle part of the fourth transmission wheel 103 is fixedly installed with the first bevel gear 104. The third transmission wheel 101, the second transmission belt 102, the fourth transmission wheel 103 and The first bevel gears 104 are movably mounted in the side walls of the mixing box 1. There are two first transmission components 9 and two second transmission components 10. The two first transmission components 9 are respectively located at the front end of the left impeller 8 and the rear end of the right impeller 8. The two impellers 8 rotate and rotate in opposite directions when the material is discharged through the opening at the bottom of the fixed block 3 to impact the rectangular plate in the impeller 8. The first transmission component 9 and the second transmission component 10 are arranged to play a transmission role, so that the force of the impeller 8 rotating can be transmitted to the stirring component 11 to rotate the stirring component 11. At the same time, due to the different ratios of the first solution and the second solution, the impact force on different impellers 8 during injection is different, resulting in different rotation speeds of the two impellers 8. The first transmission component 9 and the second transmission component 10 can ensure that the rotation speeds of the two impellers 8 are the same.

[0038] like Figure 7 As shown, the stirring assembly 11 includes a connecting rod 111, a blade 114 is fixedly installed at an equal angle in a ring shape on the outer end of the top of the connecting rod 111, a sealed bearing 112 is fixedly installed in the middle of the connecting rod 111, and a second bevel gear 113 is fixedly installed at the lower end of the connecting rod 111. The outer wheel of the sealed bearing 112 is fixedly connected to the mixing box 1, and the outer side of the second bevel gear 113 is meshed with the first bevel gear 104 in the second transmission assembly 10; the stirring assembly 11 can be rotated under the transmission of the first transmission assembly 9 and the second transmission assembly 10, and can also be rotated under the impact of the dye solution mixed by the first solution and the second solution, so that the dye solution is broken when the dye solution is less, and when the dye solution is more and hinders the rotation of the stirring assembly 11, the dye solution can be stirred by the stirring assembly 11 to promote the mixing effect.

[0039] like Figure 3As shown, the impeller 8 includes a circular connecting rod and a rectangular plate located outside the circular connecting rod, the rectangular plate blocks the opening at the bottom of the fixed block 3 in the vertical direction, and the circular connecting rod is movably connected to the mixing box 1 through a bearing; the design of the rectangular plate can better withstand the impact of the first solution and the second solution, and the first solution and the second solution are broken and mixed through the reaction force, thereby achieving a preliminary mixing effect.

[0040] like Figure 3 , Figure 4 As shown, a scale is provided in the middle of the top of the fixed block 3, and a square hole is provided at the connection between the top of the fixed block 3 and the injection tube 4. When the baffle plate 51 in the limiting assembly 5 moves to the farthest point of one end inside the fixed block 3, the corresponding hole is closed and the hole at the other end is completely connected, and the fixed block 3 and the limiting assembly 5 are sealed by a rubber ring; the baffle plate 51 can block the hole, thereby changing the flow rate of the hole, so that the flow rate of the two holes reaches a set ratio, thereby ensuring the optimal ratio between the first solution and the second solution, ensuring the use effect, and at the same time, the baffle plate 51 is moved, the structure is simple, and manpower and material resources are saved.

[0041] The present invention provides a method for uniformly feeding an autonomous dye for foam dyeing, and the method for uniformly feeding an autonomous dye for foam dyeing is as follows:

[0042] When dyeing denim indigo foam, first press the adjusting knob 61 toward the rear end to separate the first baffle 62 from the inner wall of the fixed block 3, then turn the adjusting knob 61 to drive the connecting tooth plate 53 in the limit assembly 5 to move through the matching gear 63, thereby changing the position of the shielding plate 51 inside the fixed block 3. At this time, the scale value pointed to by the pointing block 52 in the limit assembly 5 changes, showing the area ratio of the holes at the left and right ends of the fixed block 3, and the area ratio of the holes represents the ratio of the flow rate. After adjustment, release the adjusting knob 61, and the first baffle 62 contacts the inner wall of the fixed block 3 under the elastic force of the spring 7, and the rotation of the adjusting assembly 6 is prevented by the resistance of the rubber layer;

[0043] Then, indigo dye, NaOH, insurance powder, penetrant and water are respectively injected into a first solution mixed into a certain concentration and a stabilizer, foaming agent and water are mixed into a second solution mixed into a certain concentration through two injection pipes 4. Since the position of the baffle plate 51 has been adjusted in advance, the flow rates of the first solution and the second solution through the left and right ends are in a specific ratio, so there is no need for manual weighing. It should be noted that indigo dye, NaOH, insurance powder, penetrant and water are mixed into a first solution of a certain concentration, and the stabilizer, foaming agent and water are mixed into a second solution of a certain concentration, and then the first solution and the second solution are mixed to form a dye solution. In the above process, the mixing time of the foaming agent and the alkaline solution is short, the foaming agent will not be affected by the alkalinity to foam, and can be highly alkali-resistant. When mixing inside the mixing box 1, it is ensured that the inside of the mixing box 1 is in a nitrogen atmosphere to prevent the dye solution from oxidizing.

[0044] When the first solution and the second solution pass through the two injection pipes 4 through the fixed block 3 and enter the interior of the mixing box 1, the first solution and the second solution first contact the impeller 8, and the impeller 8 rotates due to the impact of gravity on the rectangular plate in the impeller 8, while the two impellers 8 rotate synchronously in opposite directions, and the first solution and the second solution that collide with the rectangular plate are broken and separated, and are mixed and fall in the middle of the two impellers 8;

[0045] When the dye solution formed by mixing the first solution and the second solution falls on the stirring component 11 and collides with the blade 114 at the top of the stirring component 11, the spiral shape of the blade 114 can drive the stirring component 11 to rotate as a whole through pressure. At the same time, due to the transmission of the first transmission component 9 and the second transmission component 10, the two impellers 8 and the stirring component 11 can rotate at the same time, and the rotation of the stirring component 11 can stir the dye solution inside the mixing box 1 to promote uniform mixing.

[0046] After the mixing is completed, the valve on the discharge pipe 2 is opened to add the mixed dye solution in the mixing box 1 into the foaming machine for foaming.

[0047] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

After adjustment, the adjusting knob (61) is released, and the first baffle plate (62) contacts the inner wall of the fixed block (3) under the elastic force of the spring (7), and the resistance of the rubber layer prevents the adjustment assembly (6) from rotating; Then, dye, NaOH, hydrosulfite, penetrant and water are respectively injected into the first solution with a certain concentration and stabilizer, foaming agent and water are mixed into the second solution with a certain concentration through the two injection pipes (4). Since the position of the baffle plate (51) is adjusted in advance, the flow rate of the first solution and the second solution passing through the left and right ends is a specific ratio, so that manual weighing is not required; When the first solution and the second solution pass through the two injection pipes (4) through the fixed block (3) and enter the interior of the mixing box (1), the first solution and the second solution first contact the impeller (8), and the impeller (8) rotates due to the impact of gravity on the rectangular plate in the impeller (8), while the two impellers (8) rotate synchronously in opposite directions, and the first solution and the second solution that collide with the rectangular plate are broken and separated, and are mixed and fall in the middle of the two impellers (8); When the dye liquid formed by mixing the first solution and the second solution falls on the stirring component (11) and collides with the blade (114) at the top of the stirring component (11), the spiral shape of the blade (114) can drive the stirring component (11) as a whole to rotate through pressure, and at the same time, due to the transmission of the first transmission component (9) and the second transmission component (10), the two impellers (8) and the stirring component (11) can rotate simultaneously, and the rotation of the stirring component (11) can stir the dye liquid inside the mixing box (1) to promote uniform mixing; After the mixing is completed, the valve on the discharge pipe (2) is opened to add the mixed dye solution in the mixing box (1) into the foaming machine for foaming.
