Technical Field

[0002] Spandex, also known as polyurethane fiber, is a synthetic fiber with extremely high elasticity. Spandex is usually blended with cotton, polyester, nylon and other fibers. Spandex blended fabrics have good shape retention, are not easy to wrinkle, and are wear-resistant, aging-resistant, and not easy to fade. Cotton and spandex blended fabrics are often dyed with reactive dyes through immersion dyeing; while polyester and spandex blended fabrics are often processed with disperse dyes through high temperature and high pressure dyeing technology.

[0003] At present, in the dyeing process, the spandex fabric is usually pretreated before dyeing to remove impurities and make the fabric surface cleaner, the spandex fabric is immersed in the dye solution for a certain period of time to ensure uniform dyeing, and the dye solution is heated according to the requirements of the dye to promote the diffusion of dye molecules into the fiber so that the dye can be firmly attached to the fiber; however, the uneven temperature of the dye solution close to the heating source and the dye solution far from the heating source will lead to uneven dyeing of the spandex fabric, and the spandex fabric immersed in the dye solution has surface wrinkles, and the wrinkled area on the surface cannot fully absorb the dye molecules, which will also lead to uneven dyeing of the spandex fabric; after dyeing is completed, the excess dye on the spandex fabric needs to be removed, usually rinsed with clean water for multiple times, but the use of clean water consumes a lot of water resources in the process of rinsing, and at the same time leads to waste of dye, which is not conducive to cost saving.

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] 1.

[0022] 3. The dye extrusion of spandex fabric is accelerated by cooperating with the dye removal mechanism and the roller smoothing mechanism to improve the discharge efficiency. The dye is extruded through a Z-shaped path to reduce the space occupied by the equipment. When the cam rotates, the horizontal plate of the point pressure plate is intermittently pressed. The horizontal plate of the point pressure plate squeezes the spandex fabric on the filter plate 1 over a large area to remove the dye initially. The upper operating plate and the two corresponding smoothing rollers on the upper and lower filter plates 2 repeatedly roll the spandex fabric to fully squeeze out the excess dye in the spandex fabric. At the same time, the surface of the fabric can be smoothed to improve the quality of the finished product. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] After the spandex fabric stays in the dyeing bin 2 for a certain period of time, the dyed spandex fabric is transferred to the discharge bin 3 through the supporting mechanism 4 for subsequent dye removal treatment. The dye removal liquid pressing mechanism 7 is adjusted to intermittently squeeze the spandex fabric, and the dye on the spandex fabric is squeezed horizontally over a large range. The roller pressing and smoothing mechanism 8 is adjusted to roll the spandex fabric in the front and back directions, so that the excess dye in the spandex fabric is fully squeezed out and the surface of the fabric is smoothed at the same time; the squeezed and filtered dye is recovered through the dye recovery component 9 and re-enters the interior of the dyeing bin 2.

[0040] Reference Figure 1 to Figure 2The support mechanism 4 includes an adaptive roller member 41, a support roller member 42 and a limit roller group 43 arranged in the dyeing chamber 2. The limit roller group 43 is arranged in the middle of the dyeing chamber 2.

The left and right sides of the limit roller group 43 are symmetrically provided with support roller members 42 rotatably connected to the inner wall of the device body 1. The adaptive roller members 41 slidably connected to the inner wall of the device body 1 are symmetrically arranged with the two support roller members 42 as the center. The adaptive roller member 41 is composed of a slider which is symmetrically arranged front and back and connected to the device body 1 by a spring (not shown in the figure) and a roller which is rotatably connected between the sliders. The support mechanism 4 also includes a discharge roller group 45 and a transition roller 44 which are distributed up and down and rotatably installed inside the discharge bin 3. The discharge roller group 45 is composed of four rollers which are staggered in a Z shape left and right. The heights of the supporting roller member 42 and the rollers located above in the limiting roller group 43 are consistent. The adaptive roller member 41 is located above the supporting roller member 42 and the limiting roller group 43.

[0041] Reference Figure 1 , Figure 3 and Figure 4 The dye liquor stirring mechanism 5 comprises a U-shaped support frame 51, the rear inner wall of the device body 1 is slidably connected to the U-shaped support frame 51 with the opening facing backward through an electric slider, the front side wall of the U-shaped support frame 51 is fixedly connected to a return-shaped limit frame 52, the upper and lower inner wall edges of the return-shaped limit frame 52 are rounded, and the front side wall of the return-shaped limit frame 52 is slidably connected to the front inner wall of the device body 1; a U-shaped adjusting member 53 is symmetrically fixedly connected to the U-shaped support frame 51, and the U-shaped adjusting member 53 is composed of a U-shaped member connected to the U-shaped support frame 51 and a rack symmetrically fixed to the side wall of the U-shaped member, the side walls of the rack of the U-shaped adjusting member 53 are meshed with a gear 54 rotatably connected to the rear inner wall of the device body 1, and a windmill member 55 rotatably connected to the front inner wall of the device body 1 is fixedly provided on the front side wall of the gear 54.

[0042] Reference Figure 1 , Figure 3 , Figure 5 and Figure 6The rolling anti-folding mechanism 6 includes a hydraulic rod 61, and the hydraulic rod 61 is installed on the rear inner wall of the device body 1 through a plate. A traction plate 62 that is slidably connected to the rear inner wall of the device body 1 is fixed on the right side wall of the hydraulic rod 61. The front side wall of the traction plate 62 is rotatably connected to multiple adjustment frames 63 through a torsion spring (not shown in the figure). The adjustment frames 63 are symmetrically distributed with the return-shaped limit frame 52 as the center. Two slide rails 64 are symmetrically arranged on the left and right side walls of the adjustment frame 63. The two slide rails 64 corresponding to the left and right on the same adjustment frame 63 are slidably connected with a squeezing roller 65; an adaptation component 66 is provided on the adjustment frame 63, and the adaptation component 66 includes an adaptation block 662. The adjustment frame 63 is symmetrically fixed with the adaptation block 662 on the rear part of the side wall close to the U-shaped support frame 51. The rear part of the left and right side walls of the U-shaped support frame 51 is fixed with a spring rod 661, and the adaptation block 662 is adapted to the spring rod 661.

[0043] The spandex fabric enters from the left entrance of the dyeing bin 2, and passes through the upper wall of the adaptive roller member 41 on the left side of the dyeing bin 2, the lower wall of the supporting roller member 42 on the left side, the middle part of the return limit frame 52 and the adjusting frame 63 on the left side, and between the two limit roller groups 43, and then passes through the middle part of the return limit frame 52 and the adjusting frame 63 on the right side, the lower wall of the supporting roller member 42 on the right side and the upper wall of the adaptive roller member 41 on the right side, and then enters the interior of the discharge bin 3, passes through the bottom wall of the transition roller 44, and then goes around to the outer wall of the staggered discharge roller group 45, and finally is discharged through the right side outlet of the discharge bin 3.

[0044] The return-shaped limiting frame 52 and the adjusting frame 63 are detachable structures, so that when different batches of spandex fabrics are replaced, the spandex fabrics are passed through the return-shaped limiting frame 52 and the adjusting frame 63 from left to right from the inside of the device main body 1. When the spandex fabrics are dyed inside the dyeing chamber 2, the U-shaped supporting frame 51 is driven to slide up and down by the electric slider, and the return-shaped limiting frame 52 is driven to pull the limited spandex fabric up and down. The smooth inner wall of the return-shaped limiting frame 52 can prevent wear on the spandex fabric. When the return-shaped limiting frame 52 pulls the spandex fabric to move, the spandex fabric oscillates up and down between the supporting roller member 42 and the limiting roller group 43, so that the spandex fabric and the dye solution are fully in contact, thereby improving the dyeing efficiency.

[0045] The U-shaped support frame 51 moves up and down, driving the U-shaped adjusting member 53 to move up and down. The U-shaped adjusting member 53 drives the gear 1 54 and the windmill member 55 to rotate. The rotating windmill member 55 stirs the dye liquid inside the dyeing chamber 2, so that the dye liquid close to the heating source and the dye liquid far away from the heating source are fully mixed, thereby preventing uneven dyeing of the spandex fabric due to uneven temperature of the dye liquid.

[0046] The U-shaped support frame 51 moves up and down intermittently. When the U-shaped support frame 51 moves up or down, the spring rod 661 pushes the adaptive block 662 to move, so that the adjustment frame 63 adaptively rotates around the front side wall of the traction plate 62, thereby reducing the obstruction and wear of the spandex fabric during the oscillation; when the spandex fabric oscillates up and down, the adaptive roller 41 adaptively slides up and down through the slider to prevent the U-shaped support frame 51 from causing excessive pulling of the spandex fabric, and the adaptive roller 41 is reset by the spring connected between the slider and the device body 1.

[0047] When the U-shaped support frame 51 moves and resets to the middle initial position, the adjustment frame 63 is reset by the elastic force of the torsion spring, and the two squeezing rollers 65 are driven by the electric slider to move back and forth on the slide rail 64. After the two squeezing rollers 65 roll back and forth on the upper and lower side walls of the spandex fabric, the hydraulic rod 61 drives the traction plate 62 to move left and right, and the adjustment frame 63 drives the squeezing rollers 65 to move to a position that does not overlap with the initial position, and the squeezing rollers 65 roll again to repeatedly roll the spandex fabric during dyeing to reduce the surface wrinkle area of ​​the spandex fabric.

[0048] Reference Figure 1 , Figure 7 and Figure 8 The destaining liquid pressing mechanism 7 includes a driving mechanism 71 and a destaining liquid component 72. The driving mechanism 71 is arranged on the rear inner wall of the device body 1, and the destaining liquid component 72 is arranged on the driving mechanism 71. The driving mechanism 71 includes two gears 712 distributed up and down, wherein the rear side wall of one gear 712 is fixed with a motor 711 installed on the rear outer wall of the device body 1, and the rear side wall of the other gear 712 is rotatably connected to the rear inner wall of the device body 1. The two gears 712 are connected by a toothed belt 714, and the front side walls of the two gears 712 are fixedly connected with a cam member 713, and the front side walls of the cam member 713 are rotatably connected to the front inner wall of the device body 1.

[0049] Reference Figures 7 and 8 The dye removal liquid component 72 includes a support bar 721, and the support bar 721 is symmetrically fixed between the front and rear inner walls of the device body 1. The support bars 721 are connected to a point pressure plate 722 for sliding up and down. The point pressure plate 722 is composed of two vertical rods slidably connected to the support bar 721 and a horizontal plate fixed to the bottom wall of the vertical rod. The bottom wall of the support bar 721 and the top wall of the horizontal plate of the point pressure plate 722 are connected with a spring sleeved on the outer wall of the vertical rod of the point pressure plate 722. A filter plate 723 fixed between the front and rear inner walls of the device body 1 is arranged below the point pressure plate 722, and a dye liquid box 724 is fixed to the bottom wall of the filter plate 723.

[0050] Reference Figure 1 , Figure 8 , Fig. 9 and Fig.10 The roller smoothing mechanism 8 includes an upper operating plate 81 and a filter plate 82 which are symmetrically distributed in the upper and lower parts. A dye box 83 is fixed to the bottom wall of the filter plate 82. A roller pressing assembly 84 is arranged on the upper operating plate 81 and the filter plate 82. The roller pressing assembly 84 includes a slide rail 841. The bottom wall of the upper operating plate 81 and the top wall of the filter plate 82 are symmetrically provided with slide rails 841. A smoothing roller 842 is connected to the two corresponding slide rails 841 on the left and right sides through an electric slider for sliding back and forth. A cleaning blade 843 corresponding to the smoothing roller 842 is arranged on the electric slider on the slide rail 841. The cleaning blade 843 is tightly attached to the side wall of the smoothing roller 842. The filter plate 723 and the filter plate 82 are both composed of a frame connected to the device body 1 and a detachable filter screen in the middle of the frame. The inner bottom walls of the dye box 724 and the roller pressing assembly 84 are inclined from the left and right sides to the middle.

[0051] Reference Figure 1 and Fig.11 The dye liquid recovery component 9 includes a suction pump 91, which is installed inside the dyeing chamber 2. A collection pipe 92 is commonly connected between the suction pump 91 and the rear side walls of the two dye liquid boxes 83 and the rear side walls of the two dye liquid boxes 724 distributed up and down. A recovery pipe 93 is connected between the suction pump 91 and the dyeing chamber 2.

[0052] When the spandex fabric is transferred from the inside of the dyeing bin 2 to the inside of the discharging bin 3 through the supporting mechanism 4, the two pressing and dye removal mechanisms 7 and the two roller pressing and smoothing mechanisms 8 are used to continuously extrude the dye, thereby improving the continuous operation of the equipment, and the extrude of the dye through the zigzag path reduces the space occupied by the equipment. The motor 711 drives the corresponding gear 2 712 and the cam member 713 to rotate, and the transmission of the toothed belt 714 causes another gear 2 712 and the corresponding cam member 713 to rotate. When the cam member 713 rotates, the horizontal plate of the point pressing plate member 722 is intermittently pressed, and the horizontal plate of the point pressing plate member 722 extrudes the spandex fabric on the filter plate 1 723 over a large area to perform preliminary removal of the dye. In this process, the spring between the point pressing plate member 722 and the supporting strip 721 is adapted to expand and contract, and the dye enters the inside of the filter plate 1 723 and flows to the inside of the dye box 1 724 for collection.

[0053] The smoothing roller 842 is driven by the electric slider to move back and forth, and the two smoothing rollers 842 on the upper operating panel 81 or the filter plate 82 move in opposite directions. The two corresponding smoothing rollers 842 above and below repeatedly roll the spandex fabric to fully squeeze out the excess dye in the spandex fabric. At the same time, the surface of the fabric can be smoothed to improve the quality of the finished product. The hair attached to the smoothing roller 842 is scraped off by the cleaning blade 843 during the rotation of the smoothing roller 842, and the cleaning blade 843 can be cleaned regularly by manual means.

[0054] The inclined inner bottom walls of dye box 1 724 and dye box 2 83 are conducive to concentrating the squeezed dye, and facilitate conveying the dye through the collection pipe 92 to the recovery pipe 93 by the suction pump 91 and then recycling it into the interior of the dyeing chamber 2, thereby realizing the reuse of the dye and reducing cost waste.

[0055] Reference Figure 1-Figure 11 The specific operation steps of this spandex fabric automatic dyeing device are as follows:

[0056] First, the spandex fabric enters from the left entrance of the dyeing chamber 2, and the supporting mechanism 4 is used to support the spread spandex fabric and adapt to the spread state of the spandex fabric. When the spandex fabric is dyed inside the dyeing chamber 2, the U-shaped supporting frame 51 is driven to slide up and down by the electric slider, and the return-shaped limiting frame 52 is driven to pull the limited spandex fabric section up and down. The spandex fabric oscillates up and down and fully contacts the dye liquid, and the windmill part 55 rotates to stir the dye liquid inside the dyeing chamber 2; the two squeezing rollers 65 move forward and backward, and the hydraulic rod 61 drives the traction plate 62 and the squeezing roller 65 to move left and right to adjust the position. During the dyeing, the squeezing roller 65 repeatedly rolls the spandex fabric.

[0057] When the spandex fabric is transferred from the inside of the dyeing bin 2 to the dye removal pressing mechanism 7, the motor 711 drives the cam member 713 to rotate, and the horizontal plate of the pressure plate member 722 squeezes the spandex fabric on the filter plate 1 723 over a large area to remove the dye liquid preliminarily; when it is transferred to the roller smoothing mechanism 8, the two smoothing rollers 842 repeatedly roll the spandex fabric to fully squeeze out the excess dye liquid in the spandex fabric and smooth the surface of the fabric at the same time.
