Description

Technical Field

[0001] This invention belongs to the field of dyeing equipment technology, specifically a loose-hair dyeing machine for uniform dyeing. Background Technology

[0002] Loose wool dyeing, as one of the important methods of dyeing wool products, is widely used in the processing and production of loose fibers such as woolen tweed, overcoat tweed, and blankets due to its advantages such as high color fastness and convenient process control. Currently, loose wool dyeing machines on the market usually use a dyeing tank as the core dyeing space, with a loose wool barrel inside to hold the loose fibers to be dyed. Through a porous mandrel or similar guide structure set in the loose wool barrel, the dye liquor is driven by a water pump to achieve circulation, so that the dye liquor penetrates the loose fibers to complete the dyeing process.

[0003] Patent publication number CN204898289U discloses a loose fiber dyeing machine, including a base and a dyeing tank set on the base. A loose fiber barrel is installed inside the dyeing tank, and a hollow porous mandrel is installed inside the loose fiber barrel. A nozzle is installed at the bottom of the porous mandrel, and the nozzle is connected to a dye liquor circulation pump. The other end of the dye liquor circulation pump is connected to the dyeing tank. A horizontal connecting rod is installed at the top of the dyeing tank, and vertical connecting rods are installed at both ends of the horizontal connecting rod. A base plate that can be inserted between the loose fiber barrel and the porous mandrel is installed at the bottom of the vertical connecting rod. Vertical openings corresponding to the two vertical connecting rods are provided on the side wall of the loose fiber barrel, and the two vertical connecting rods can move up and down along the vertical openings. This patent can avoid a large color difference between the top and bottom of the loose fiber during dyeing, thereby improving the dyeing effect.

[0004] The existing technical solutions mentioned above have the following drawbacks: the existing loose wool dyeing machine only relies on a water pump to drive the dye liquor to unidirectional circulation. The dye liquor mainly penetrates along a fixed path on the inner wall of the loose wool barrel. For the compacted loose wool in the middle area of ​​the loose wool barrel, the dye liquor cannot penetrate quickly and achieve uniform dyeing, resulting in a slow dyeing speed. The installation and fixing of the pressing cover is cumbersome. It is necessary to use hoisting equipment to lift the pressing cover to the designated position and then manually rotate the screw to complete the positioning and fixing. This is not only time-consuming and labor-intensive, but also reduces production efficiency. Summary of the Invention

The water inlet of the water pump is connected to the stirring tank through a connecting pipe. The water outlet of the water pump is connected to a three-way pipe. One end of the three-way pipe is connected to an electric three-way valve one. One end of the electric three-way valve one penetrates into the dyeing cylinder, and the other end of the electric three-way valve one penetrates into the interior of the stirring tank. The other end of the three-way pipe is connected to an electric three-way valve two. One end of the electric three-way valve two penetrates into the inner cylinder, and the other end of the electric three-way valve two penetrates into the dyeing cylinder.

[0010] In the above technical solution, preferably, the automatic rotation component includes a pad fixedly connected inside the sealing cover, a motor fixedly connected to the bottom of the pad, a support wheel fixedly connected to the output end of the motor, a toothed ring fixedly connected to the support wheel, the guide toothed tube meshing with the toothed ring, and a self-driving component provided on the top plate.

[0012] In the above technical solution, preferably, a limiting ring is fixedly connected to the pressure cap, a limiting rod is provided inside the limiting ring, and the top end of the limiting rod is fixedly connected to the bottom of the support wheel.

[0013] In the above technical solution, preferably, the bottom of the pressure cap is provided with an elastic clamping member, the elastic clamping member includes a pressure ring provided at the bottom of the pressure cap, a spring is fixedly connected to the pressure ring, the top end of the spring is fixedly connected to the bottom of the pressure cap, the pressure ring is sleeved on the guide tooth tube, and a trapezoidal cylinder is fixedly connected to the bottom of the pressure cap, the bottom end of the trapezoidal cylinder extends to the bottom of the pressure ring, and the trapezoidal cylinder is sleeved on the guide tooth tube.

[0014] In the above technical solution, preferably, the sleeve plate is provided with an anti-tilt component, the anti-tilt component includes a concave sleeve fixedly connected to the sleeve plate, a sliding plate is slidably connected inside the concave sleeve, one side of the sliding plate is fixedly connected to the top plate, and two support plates are symmetrically fixedly connected to the concave sleeve, one end of the support plate is fixedly connected to the cylinder.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses a lifting device to drive the sealing cap to rise, fall, and rotate, which in turn drives the guide tube to insert into the compacted loose fibers. This allows the dye liquor discharged from the inner and outer cylinders to directly reach the middle area for rapid dyeing, improving dyeing efficiency. The circulating liquid delivery component can switch the dye liquor path to achieve internal and external circulation of the dye liquor. It eliminates the need for manual fixing of the cap, making operation convenient and labor-saving. It improves the positioning accuracy of the cap, reduces labor intensity, and optimizes the overall dyeing uniformity and production efficiency to meet the needs of large-scale production.

[0016] Furthermore, the guide tube can only be inserted into loose fibers for fixed-direction dyeing, limiting the dye diffusion path. For compacted loose fibers, especially in the middle area, the dye penetration speed is still slow and the diffusion is uneven. However, through the design of the pad, motor, and support wheel in the automatic rotating component, the top plate will start the motor through the self-driving component when it moves. The motor drives the support wheel and the toothed ring to rotate. Through the meshing transmission between the toothed ring and the guide tube, the guide tube is driven to rotate and drain the dye, covering all areas of the loose fibers in all directions. This accelerates the dye penetration of the compacted loose fibers in the middle, further enhances the dyeing uniformity, greatly improves the dyeing efficiency, and meets the needs of large-scale and efficient production.

[0017] Furthermore, the fixed lowering height of the pressure cap makes it impossible to adaptively adjust according to the amount of loose wool loaded, resulting in difficulty in effectively clamping loose wool with different loading amounts. However, through the design of the pressure ring, spring, and trapezoidal cylinder in the elastic clamping component, the pressure ring is elastically connected to the pressure cap through the spring, and the clamping force can be adaptively adjusted according to the amount of loose wool loaded, achieving effective clamping and avoiding problems such as loosening or excessive compression; the trapezoidal cylinder can guide and support the pressure ring, improving the stability of the pressure ring.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] like Figures 1 to 3 As shown, the present invention provides a loose-hair dyeing machine for uniform dyeing, including a base plate 1, a dyeing cylinder 2 fixedly connected to the base plate 1, an inner cylinder 3 fixedly connected inside the dyeing cylinder 2, an outer cylinder 4 fixedly connected inside the dyeing cylinder 2, and a stirring tank 5 fixedly connected to the base plate 1, and further including: The self-lifting guide component 6 is set on the base plate 1 to improve the dyeing efficiency of the dye liquor on loose hair. The self-lifting guide component 6 includes a sealing cover 61 disposed inside the dyeing cylinder 2, a connecting sleeve 62 fixedly connected to the bottom of the sealing cover 61, a pressure cap 63 fixedly connected to the bottom of the connecting sleeve 62, the bottom of the pressure cap 63 extending into the interior of the inner cylinder 3, a guide tooth tube 64 disposed inside the connecting sleeve 62, the bottom end of the guide tooth tube 64 penetrating to the bottom of the pressure cap 63, two symmetrically arranged liquid inlets 65 opened on the guide tooth tube 64, a lifting device 66 disposed on the base plate 1, an anti-backflow component 67 disposed inside the pressure cap 63, and a circulating liquid delivery component 68 fixedly connected to the base plate 1; The lifting device 66 drives the sealing cover 61 to move in the direction of approaching / moving away from the inner cylinder 3, thereby causing the guide tooth tube 64 to be inserted / not inserted into the dyeing cylinder 2; The automatic rotation component 7 is located at the bottom of the sealing cover 61 and is used to automatically drive the guide tooth tube 64 to rotate and drain liquid.

[0022] Specifically, the guide tube 64 has several drainage holes; the dyeing cylinder 2 has a loose wool support plate inside, which is fitted onto the inner cylinder 3. The four corners of the top of the loose wool support plate are fixedly connected to lifting chains. The loose wool support plate is used to support the loose wool, making it convenient to lift out the dyed loose wool using lifting equipment and lifting chains. The inner cylinder 3 and the outer cylinder 4 both have several evenly distributed micro-holes. The micro-holes are used to guide the dye liquor, making it convenient for the dye liquor to be evenly distributed inside the dyeing cylinder 2. The stirring tank 5 is fixedly connected to a motor. The output end of the motor passes through the inside of the stirring tank 5 and is fixedly connected to a stirring rod. The inside of the stirring tank 5 is fixedly connected to a heating rod. The motor can stir the dye liquor through the stirring rod, and the heating rod can heat the dye liquor.

[0023] like Figures 1 to 3 As shown, the lifting device 66 includes two sleeve plates 661 hinged to the base plate 1 by a shaft. A cylinder 662 is fixedly connected inside the sleeve plate 661. A top plate 663 is fixedly connected to the sealing cover 61. The output end of the cylinder 662 is fixedly connected to the bottom of the top plate 663. Two symmetrically arranged cylinders 664 are hinged to the base plate 1 via shafts. The output end of cylinder 664 is hinged to cylinder 662 via shafts.

[0024] Specifically, during use, cylinder 662 can drive the top plate 663 and the sealing cover 61 to move upward, so that the sealing cover 61 drives the guide tooth tube 64 to move upward through the connecting sleeve 62 and the pressure cover 63. When the guide tooth tube 64 is separated from the dyeing cylinder 2, cylinder 664 can drive cylinder 662 to rotate around the shaft, so that the guide tooth tube 64 tilts away from the top of the dyeing cylinder 2, and will not affect the lifting of loose wool.

[0025] like Figure 1 As shown, two baffles 8 are symmetrically fixedly connected to the dyeing cylinder 2, and a positioning plate 9 is fixedly connected to the baffles 8. One side of the positioning plate 9 is fixedly connected to the dyeing cylinder 2.

[0026] Specifically, the positioning plate 9 and the baffle 8 can limit the position of cylinder 662, ensuring that the sealing cover 61 and the guide tooth tube 64 can be accurately returned to their positions, preventing cylinder 662 from rotating excessively, and ensuring operational safety.

[0027] like Figure 3 and Figure 7As shown, the anti-backflow assembly 67 includes a concave tube 671 connected to the top of the pressure cap 63. One end of the concave tube 671 extends into the interior of the outer cylinder 4. A sealing plate 672 is hinged to the interior of the pressure cap 63 via a torsion spring hinge. The top of the sealing plate 672 contacts the bottom of the concave tube 671. Two sector plates 673 are hinged to the interior of the pressure cap 63 via a torsion spring hinge. The bottom of the sector plates 673 contacts the inner wall of the pressure cap 63.

[0028] Specifically, the outer cylinder 4 has a round hole at its top, through which it is fitted onto the concave tube 671; the bottom of the pressure cap 63 has two symmetrically arranged arc-shaped openings, with the fan-shaped plate 673 located at the top of the arc-shaped openings; during use, when dyeing from the inside out, the circulating liquid delivery component 68 injects the dye into the inner cylinder 3, the dye pushes open the fan-shaped plate 673 and enters the interior of the pressure cap 63, and part of the dye enters the interior of the guide toothed tube 64 through the liquid inlet 65, and the guide toothed tube 64 discharges the dye to dye loose hair; when dyeing from the outside in, the circulating liquid delivery component 68 injects the dye into the interior of the outer cylinder 4, and part of the dye pushes open the sealing plate 672 through the concave tube 671 and enters the interior of the pressure cap 63 and the guide toothed tube 64, and then discharges the dye through the guide toothed tube 64. The sealing plate 672 and the fan-shaped plate 673 can effectively prevent the dye from being discharged directly without being used.

[0029] like Figures 2 to 4 As shown, the circulating liquid delivery assembly 68 includes a water pump 681 fixedly connected to the base plate 1. The water inlet of the water pump 681 is connected to the mixing tank 5 through a connecting pipe. The drain of the water pump 681 is connected to a three-way pipe 682. One end of the three-way pipe 682 is connected to an electric three-way valve 683. One end of the electric three-way valve 683 extends into the dyeing cylinder 2, and the other end of the electric three-way valve 683 extends into the interior of the mixing tank 5. The other end of the three-way pipe 682 is connected to an electric three-way valve 684. One end of the electric three-way valve 684 extends into the inner cylinder 3, and the other end of the electric three-way valve 684 extends into the dyeing cylinder 2.

[0030] Specifically, during dyeing from the inside out, the electric three-way valve 684 connects the inner cylinder 3 to the three-way pipe 682, and the electric three-way valve 683 connects the dyeing cylinder 2 to the stirring tank 5. The water pump 681 injects the dye solution into the inner cylinder 3 through the three-way pipe 682 and the electric three-way valve 684. After the inner cylinder 3 discharges the dye solution to dye the loose hair, it is discharged into the stirring tank 5 through the outer cylinder 4 and the electric three-way valve 683. During dyeing from the outside in, the electric three-way valve 683 connects the inner cylinder 3 to the stirring tank 5, and the electric three-way valve 683 connects the dyeing cylinder 2 to the three-way pipe 682. The water pump 681 injects the dye solution into the dyeing cylinder 2 through the three-way pipe 682 and the electric three-way valve 683. After the outer cylinder 4 discharges the dye solution to dye the loose hair, it is discharged into the stirring tank 5 through the inner cylinder 3 and the electric three-way valve 684. This achieves internal and external circulation dyeing.

[0031] like Figure 5 and Figure 9 As shown, the automatic rotating assembly 7 includes a pad 71 fixedly connected inside the sealing cover 61, a motor 72 fixedly connected to the bottom of the pad 71, a support wheel 73 fixedly connected to the output end of the motor 72, a toothed ring 74 fixedly connected to the support wheel 73, a guide toothed tube 64 meshing with the toothed ring 74, and a self-driving component 75 provided on the top plate 663.

[0032] Specifically, motor 72 is a waterproof geared motor; when the top plate 663 moves, it will start motor 72 through self-driving component 75. Motor 72 drives support wheel 73 and gear ring 74 to rotate. Through the meshing transmission between gear ring 74 and guide tooth tube 64, the guide tooth tube 64 is driven to rotate and discharge liquid, which fully covers all areas of loose wool, accelerates the penetration of dye liquor in the middle of compacted loose wool, further enhances dyeing uniformity, greatly improves dyeing efficiency, and adapts to the needs of large-scale and efficient production.

[0033] like Figure 1 As shown, the self-driving component 75 includes a pressure plate 751 fixedly connected to the top plate 663. A jog switch 752 is provided at the bottom of the pressure plate 751, and one side of the jog switch 752 is fixedly connected to the cylinder 662.

[0034] Specifically, when the top plate 663 moves downward to the designated position, the top plate 663 will drive the pressure plate 751 to squeeze the jog switch 752, and the jog switch 752 will automatically start the motor 72 to run; when the top plate 663 moves upward, the pressure plate 751 will disengage from the jog switch 752, realizing the automatic shutdown of the motor 72 without the need for manual operation to start and stop the motor 72, thus achieving precise synchronization between the lifting and lowering movements of the motor 72 and the guide tooth tube 64.

[0035] like Figure 9 As shown, a limiting ring 10 is fixedly connected to the pressure cap 63, and a limiting rod 11 is provided inside the limiting ring 10. The top end of the limiting rod 11 is fixedly connected to the bottom of the support wheel 73.

[0036] Specifically, the combination of the limiting ring 10 and the limiting rod 11 can precisely limit the rotation trajectory of the support wheel 73 and the guide tooth tube 64, preventing deviation and shaking during rotation and ensuring the stability of the guide tooth tube 64 in rotating and draining liquid; at the same time, it limits the axial displacement of the guide tooth tube 64 to avoid collision with other components when it is raised / lowered / rotated.

[0037] like Figures 5 to 8As shown, the bottom of the pressure cap 63 is provided with an elastic clamping member 12. The elastic clamping member 12 includes a pressure ring 121 provided at the bottom of the pressure cap 63. A spring 122 is fixedly connected to the pressure ring 121. The top end of the spring 122 is fixedly connected to the bottom of the pressure cap 63. The pressure ring 121 is sleeved on the guide tooth tube 64. A trapezoidal cylinder 123 is fixedly connected to the bottom of the pressure cap 63. The bottom end of the trapezoidal cylinder 123 extends through to the bottom of the pressure ring 121. The trapezoidal cylinder 123 is sleeved on the guide tooth tube 64.

[0038] Specifically, the spring 122 is a stainless steel spring, and the pressure ring 121 is elastically connected to the pressure cover 63 through the spring 122. It can adaptively extend and adjust the clamping force according to the amount of loose wool loaded, so as to achieve effective clamping and avoid the problems of loosening / excessive compression. The trapezoidal cylinder 123 can guide and support the pressure ring 121, improving the stability of the pressure ring 121.

[0039] like Figure 1 and Figure 6 As shown, an anti-tilt component 13 is provided on the sleeve plate 661. The anti-tilt component 13 includes a concave sleeve 131 fixedly connected to the sleeve plate 661. A slide plate 132 is slidably connected inside the concave sleeve 131. One side of the slide plate 132 is fixedly connected to the top plate 663. Two support plates 133 are symmetrically fixedly connected to the concave sleeve 131. One end of the support plate 133 is fixedly connected to the cylinder 662.

[0040] Specifically, when the cylinder 662 is not rotating and after it is rotating, the concave sleeve 131 and the sliding plate 132 can provide stable support and guidance for the top plate 663 and the guide tooth tube 64, suppress component swaying and displacement, and ensure structural stability; at the same time, they disperse the force at the connection between the top plate 663 and the cylinder 662, avoid the risk of fracture caused by stress concentration, improve structural strength and equipment reliability, and extend the life of key components.

[0041] Working principle and usage process of this invention: Place the loose wool tray used to lift the loose wool into the dyeing cylinder 2, and then spread the loose wool inside the dyeing cylinder 2; add the prepared dye solution into the mixing tank 5, start the motor to drive the stirring rod to stir and mix evenly, and at the same time heat the dye solution to the required temperature through the electric heating rod to prepare for the dyeing process. Start cylinder 2 664, which drives cylinder 1 662 to rotate to a vertical position. Then, shut off cylinder 2 664 and start cylinder 1 662. Cylinder 1 662 drives the sealing cover 61 to move down through the top plate 663. The sealing cover 61 drives the pressure cover 63 to move down synchronously through the connecting sleeve 62. The pressure ring 121 at the bottom of the pressure cover 63 is elastically pressed against the surface of the loose fibers by the spring 122 to prevent the loose fibers from loosening or being excessively squeezed. Then, the bottom of the pressure cover 63 will be inserted into the inner cylinder 3. The sealing cover 61 seals the dyeing cylinder 2. The guide tooth tube 64 is precisely inserted into the middle area of ​​the loose fiber pile, creating conditions for the dye liquor to reach the core area of ​​the loose fibers. When dyeing from the inside out, the water pump 681 injects the dye solution into the inner cylinder 3 through the three-way pipe 682 and the electric three-way valve 684. After the inner cylinder 3 discharges the dye solution to permeate and dye the loose hair, it is discharged into the stirring tank 5 through the outer cylinder 4 and the electric three-way valve 683, completing the circulation from the inside out. When dyeing from the outside in, the reverse is true. The sealing plate 672 and the fan-shaped plate 673 automatically close when the dye solution flows in the opposite direction to prevent the dye solution from flowing back before it has fully permeated the hair, thus ensuring the utilization rate of the dye solution. When the top plate 663 moves down to the designated position, the top plate 663 drives the pressure plate 751 to squeeze the jog switch 752, which automatically triggers the motor 72 to start: the motor 72 drives the support wheel 73 to rotate, and the toothed ring 74 on the support wheel 73 meshes with the guide toothed tube 64, which drives the guide toothed tube 64 to slowly rotate and discharge the dye in the pile of loose hair. The dye liquor covers all areas of the loose hair in all directions, accelerates the penetration of the dye liquor in the compacted loose hair in the middle, and further improves the dyeing uniformity. After the dyeing process is completed, the water pump 681 and motor 72 are turned off. The cylinder 662 is started to retract, which moves the top plate 663 upward. The sealing cover 61 and the pressure cover 63 rise synchronously, and the guide tooth tube 64 is separated from the pile of loose fibers. Then, the cylinder 664 extends and pushes the cylinder 662 to rotate around the hinge shaft, which causes the guide tooth tube 64 to tilt away from the top of the dyeing cylinder 2 to avoid interfering with the removal of loose fibers. The dyed loose fibers are lifted out of the dyeing cylinder 2 by the hoisting chain connected to the loose fiber tray through the hoisting equipment, thus completing the entire dyeing process.
