A vertical dyeing machine

Abstract

This utility model discloses a vertical dyeing machine, belonging to the field of fabric dyeing technology. It includes a cylinder with a dyeing rack inside. A driving device is located below the cylinder, driving the dyeing rack to move up and down reciprocally within the cylinder. A central slide rail, fixed to the cylinder, is installed inside the dyeing rack, and the dyeing rack slides vertically along the central slide rail. In use, the space between the cylinder and the central slide rail is filled with dye liquor. The fabric is wrapped around the dyeing rack, and the driving device drives the central slide rail to move up and down reciprocally. This reciprocating motion between the central slide rail and the cylinder causes the dyeing rack to move the fabric up and down within the dye liquor, creating a water flow that penetrates both inside and out, resulting in uniform dyeing. By eliminating the need for a dye liquor circulation pump and related piping, the dyeing rack can dye small fabrics weighing 1-2 kg, improving both dyeing efficiency and quality.

Description

Technical Field

[0001] This utility model belongs to the field of dyeing technology, and in particular relates to a vertical dyeing machine. Background Technology

[0002] Dyeing machines are industrial devices that achieve dyeing through mechanical structures, primarily used in textile material processing and biomedical fields. In the textile sector, machines are constructed entirely of stainless steel and include types such as rope dyeing and flat-width pad dyeing. Energy consumption is reduced through low liquor ratio design (minimum 1:2.5) and intelligent control systems. Modern models incorporate environmentally friendly technologies such as supercritical carbon dioxide dyeing and electrolytic indigo processes, achieving a carbon dioxide recovery rate of up to 95% and reducing carbon emissions by 70%.

[0003] As living standards improve, people have increasingly strong demands for personalized clothing, resulting in textile printing and dyeing companies receiving more and more small-batch, diversified orders. In particular, printing and dyeing companies for clothing accessories such as yarn packages, threads, and zippers are seeing a growing number of small orders of 1-2 kg.

[0004] Traditional dyeing vats rely on a main pump to circulate the dye liquor through a circulation pipeline. This method works fine for large dyeing vats, but for smaller vats under 2 kg, the circulation pipeline occupies a large proportion of the unit area, resulting in an excessively high dyeing bath ratio that cannot be effectively controlled. In addition, contamination of the pipeline and circulation pump leads to dyeing distortion, a large number of rework processes, decreased product quality, unstable delivery times, wasted manpower and energy, increased sewage discharge, and other problems. Utility Model Content

[0005] The purpose of this invention is to provide a vertical dyeing machine that can effectively dye small-weight fabrics weighing 1-2KG, effectively solving the problems of dyeing distortion, large-scale rework, and reduced product quality caused by the inability to effectively control the liquor ratio in the prior art.

[0006] The present invention adopts the following technical solution: A vertical dyeing machine includes a cylinder body, a dyeing rack inside the cylinder body, and a drive device located below the cylinder body. The drive device drives the dyeing rack to move up and down reciprocally inside the cylinder body. A central slide rail fixedly mounted to the cylinder body is provided inside the dyeing rack. The dyeing rack and the central slide rail slide together in the vertical direction. A central slide rod passes through the central slide rail in the vertical direction. The top end of the central slide rod is fixedly mounted to the dyeing rack, and the bottom end of the central slide rod is connected to the output end of the drive device.

[0007] Furthermore, a connecting plate is fixedly installed at the bottom of the outer surface of the central slide rail, and the connecting plate is fixedly installed to the inner bottom wall of the cylinder.

[0008] Furthermore, the dyeing rack includes an upper rack ring and a lower rack ring, with several support rods fixedly arranged between the upper rack ring and the lower rack ring, and a central sliding rod fixedly arranged with the upper rack ring.

[0009] Furthermore, a cylindrical filter screen is fixedly installed on the lower end face of the lower frame ring, an upper ring plate is fixedly installed on the upper end face of the cylindrical filter screen, a lower ring plate is fixedly installed on the lower end face of the cylindrical filter screen, and an upper sealing ring is embedded in the inner side wall of both the lower frame ring and the upper ring plate.

[0010] Furthermore, a fixed plate is coaxially fixed inside the upper ring. A through hole is opened on the upper end face of the fixed plate. A threaded post with an outer diameter equal to the inner diameter of the through hole is fixed on the upper end face of the central slide rod. The diameter of the threaded post is smaller than that of the central slide rod. The threaded post passes upward through the through hole of the fixed plate and is then threadedly connected to a locking nut.

[0011] Furthermore, the upper and lower ends of the central slide rail are respectively provided with an upper chamber and a lower chamber, which are connected through a central hole. An upper plug is threadedly connected to the upper chamber of the central slide rail, and a sliding hole is provided inside the upper plug. A lower plug is threadedly connected to the lower chamber of the central slide rail, and a sliding sleeve is provided inside the lower plug. The central slide rod passes through the sliding hole of the upper plug, the central hole, the lower chamber, and the sliding sleeve from top to bottom, and then connects to the output end of the drive device.

[0012] Furthermore, the lower end face of the lower plug is provided with a stepped hole, and the sliding sleeve is inserted into the stepped hole and fixedly embedded with the lower plug; the inner plug is threadedly connected in the stepped hole, and the central sliding rod is sleeved with the inner plug.

[0013] Furthermore, an inlet pipe and an outlet pipe are installed at corresponding positions between the lower end face of the cylinder and the central slide rail and the inner side wall of the cylinder.

[0014] Furthermore, a lower sealing ring is inlaid on the outer surface of the lower ring plate, and the lower sealing ring slides in contact with the inner wall of the cylinder; a predetermined gap is reserved between the outer surface of the lower ring plate and the central slide rail.

[0015] Furthermore, the lower end face of the cylinder is fixedly provided with several legs, and the driving device includes a hydraulic telescopic rod fixedly arranged between the several legs, with the output end of the hydraulic telescopic rod fixedly arranged with the bottom end of the central slide rod.

[0016] This utility model has the following advantages: I. This utility model, by setting up a cylinder, dyeing rack, driving device, central slide rail, and central slide rod, allows the area between the cylinder and the central slide rail to be filled with dye liquor during use. The fabric is then wrapped around the dyeing rack, and the driving device drives the central slide rod to move up and down reciprocally. The central slide rod, in turn, drives the dyeing rack to move up and down reciprocally. The dyeing rack generates up-and-down reciprocating motion between the central slide rail and the cylinder, thereby causing the dyeing rack to move the fabric up and down reciprocally within the dye liquor, forming a water flow that penetrates both inside and outside, resulting in uniform dyeing. Since the circulation pump and related pipelines of the dye liquor are omitted, the dyeing rack can be used to dye small-weight fabrics of 1-2 kg, improving dyeing efficiency and quality.

[0017] II. This utility model, by setting up an upper frame ring, a lower frame ring, and a support rod, allows the fabric to be wound around the support rod during use. The central slide rod is fixedly set with the upper frame ring. The central slide rod drives the support rod and the lower frame ring to move up and down through the upper frame ring, thereby causing the support rod to drive the fabric to move up and down, achieving the purpose of uniform dyeing.

[0018] Third, this utility model is applicable to different fabrics such as yarn, thread, webbing, and cloth, and can effectively avoid dyeing distortion and improve product quality. Attached Figure Description

[0021] The following is in conjunction with the appendix Figures 1 to 9 The present invention will be described in detail with reference to the embodiments: The vertical dyeing machine of this utility model includes a cylinder 1, a dyeing rack inside the cylinder 1, and a driving device below the cylinder 1. The driving device drives the dyeing rack to move up and down reciprocally inside the cylinder 1. A central slide rail 2 is fixedly installed inside the dyeing rack and is slidably installed along the central slide rail 2 in the vertical direction. A central slide rod 3 passes through the central slide rail 2 in the vertical direction. The top end of the central slide rod 3 is fixedly installed to the dyeing rack, and the bottom end of the central slide rod 3 is connected to the output end of the driving device. In use, the space between the cylinder 1 and the central slide rail 2 is filled with dye liquor. The fabric is wrapped around the dyeing rack, and the driving device drives the central slide rod 3 to move up and down reciprocally. The central slide rod 3 drives the dyeing rack to move up and down reciprocally. The dyeing rack generates up and down reciprocating motion between the central slide rail 2 and the cylinder 1, thereby causing the dyeing rack to move the fabric up and down reciprocally in the dye liquor, forming water flow that penetrates inside and out, resulting in uniform dyeing.

[0022] In this embodiment, a connecting plate 4 is fixedly installed at the bottom of the outer surface of the central slide rail 2. The connecting plate 4 is fixedly installed with the inner bottom wall of the cylinder body 1, so as to achieve the purpose of fixing the central slide rail 2 and the cylinder body 1.

[0023] In this embodiment, the dyeing rack includes an upper rack ring 5 and a lower rack ring 6. Several support rods 7 are fixedly arranged between the upper rack ring 5 and the lower rack ring 6. The fabric is wound around the support rods 7. The central slide rod 3 is fixedly arranged with the upper rack ring 5. The central slide rod 3 drives the support rods 7 and the lower rack ring 6 to move up and down through the upper rack ring 5, thereby causing the support rods 7 to drive the fabric to move up and down, so as to achieve the purpose of uniform dyeing.

[0024] In this embodiment, a cylindrical filter screen 8 is fixedly installed on the lower end face of the lower frame ring 6, an upper ring plate 9 is fixedly installed on the upper end face of the cylindrical filter screen 8, and a lower ring plate 10 is fixedly installed on the lower end face of the cylindrical filter screen 8. An upper sealing ring 11 is embedded in the inner side wall of both the lower frame ring 6 and the upper ring plate 9. When the central slide rod 3 moves up and down, driving the lower frame ring 6 and the upper ring plate 9 to move up and down, the upper sealing ring 11 of the lower frame ring 6 and the upper ring plate 9 slides in close contact with the outer surface of the central slide rail 2.

[0025] In this embodiment, a fixed plate 12 is coaxially fixed inside the upper ring 5. A through hole 20 is opened on the upper end face of the fixed plate 12. A threaded post 13 with an outer diameter equal to the inner diameter of the through hole 20 is fixedly installed on the upper end face of the central slide rod 3. The diameter of the threaded post 13 is smaller than that of the central slide rod 3. The threaded post 13 passes upward through the through hole 20 of the fixed plate 12 and is then threadedly connected to a locking nut 14, so that the central slide rod 3 and the locking nut 14 clamp the fixed plate 12, thereby fixing the central slide rod 3 and the fixed plate 12.

[0026] In this embodiment, the upper end face and the lower end face of the central slide rail 2 are respectively provided with an upper chamber 15 and a lower chamber 16. The upper chamber 15 and the lower chamber 16 are connected through a middle hole 17. The upper chamber 15 of the central slide rail 2 is internally threaded with an upper plug 18. The upper plug 18 is internally provided with a sliding hole 19. The lower chamber 16 of the central slide rail 2 is internally threaded with a lower plug 21. The lower plug 21 is provided with a sliding sleeve 22. The central slide rod 3 passes through the sliding hole 19 of the upper plug 18, the middle hole 17, the lower chamber 16 and the sliding sleeve 22 from top to bottom and is then connected to the output end of the driving device. The driving device drives the central slide rod 3 to move up and down. The central slide rod 3 slides up and down in the central slide rail 2 and then drives the support rod 7 and the lower frame ring 6 to move up and down through the upper frame ring 5.

[0027] In this embodiment, a stepped hole is provided on the lower end face of the lower plug 21, and the sliding sleeve 22 is inserted into the stepped hole and fixedly embedded with the lower plug 21; an inner plug 23 is threadedly connected in the stepped hole, and the central sliding rod 3 is sleeved with the inner plug 23; when the central sliding rod 3 moves up and down, the central sliding rod 3 and the sliding sleeve 22 slide against each other.

[0028] In this embodiment, an inlet pipe 24 and an outlet pipe 25 are installed at corresponding positions between the lower end face of the cylinder 1 and the central slide rail 2 and the inner side wall of the cylinder 1. In use, the dye liquor enters the space between the cylinder 1 and the central slide rail 2 through the inlet pipe 24. When the set liquid level is reached, the driving device drives the central slide rod 3 to slide up and down, thereby moving the support rod 7 up and down. The fabric wrapped on the support rod 7 moves up and down in the dye liquor, forming a water flow that penetrates inside and out, resulting in uniform dyeing. At the same time as the support rod 7 moves up and down, it also drives the cylindrical filter screen 8 to move up and down, increasing the disturbance of the dye liquor and improving the dyeing efficiency.

[0029] In this embodiment, a lower sealing ring 26 is inlaid on the outer surface of the lower ring plate 10, and the lower sealing ring 26 slides in contact with the inner side wall of the cylinder 1; a predetermined gap (not shown in the figure) is reserved between the lower ring plate 10 and the outer surface of the central slide rail 2, and the dyeing liquid entering through the inlet pipe 24 enters upward from the reserved gap between the lower ring plate 10 and the outer surface of the central slide rail 2 into the space between the cylindrical filter screen 8 and the cylinder 1 and between the support rod 7 and the cylinder 1.

[0030] In this embodiment, a fixing rod 27 is fixedly provided on the outer surface of the cylinder body 1. A hinge rod 28 is hinged to the outer end of the fixing rod 27. A cylinder cover 29 is rotatably connected to the outer end of the hinge rod 28. The cylinder cover 29 seals the upper opening of the cylinder body 1. In use, the cylinder cover 29 is opened by rotating the hinge rod 28, and fabric is wrapped around the support rod 7. Then the cylinder cover 29 is fastened to the cylinder body 1.

[0031] In this embodiment, a plurality of locking blocks 30 are uniformly fixed along the circumference on the outer surface of the cylinder head 29, and a locking ring 31 is fitted on the cylinder body 1. The inner sidewall of the locking ring 31 is provided with an annular groove 32, and the upper end face of the locking ring 31 is provided with a plurality of notches 33 corresponding to the locking blocks 30. Each notch 33 is connected to the annular groove 32. When the cylinder head 29 is fastened on the cylinder body 1, the locking ring 31 is lifted upward so that each locking block 30 enters the annular groove 32 from the notch 33. Then the locking ring 31 is rotated to fix the locking ring 31 and the locking blocks 30, thereby fixing the cylinder head 29 and the cylinder body 1.

[0032] In this embodiment, two air pipes 34 are fixedly installed on the outer surface of the cylinder 1. One air pipe 34 receives compressed air, causing the air above the dye solution in the cylinder 1 to be filled with compressed air, thereby increasing the pressure of the dye solution and improving dyeing efficiency. The other air pipe 34 is equipped with a safety valve (not shown in the figure). When the pressure inside the cylinder 1 reaches the set pressure of the installed valve, the safety valve opens, releasing the compressed air inside the cylinder 1 to the outside. When the pressure inside the cylinder 1 drops to the set pressure of the installed valve, the safety valve closes. The setting of the safety valve limits the maximum pressure inside the cylinder 1.

[0033] In this embodiment, a water jacket 35 is provided on the lower part of the outer surface of the cylinder 1. Two water pipes 36 are fixedly installed on the outer surface of the water jacket 35. In use, hot water enters the water jacket 35 from the lower water pipe 36, causing the hot water to flow around the outer surface of the cylinder 1 and then flow out from the upper water pipe 36, thereby achieving the purpose of heating the dye solution in the cylinder 1. During heating, the pressure inside the cylinder 1 may increase. When the pressure reaches the set pressure of the safety valve, the safety valve opens to release the pressure in the cylinder 1. When the pressure inside the cylinder 1 decreases to below the set pressure of the safety valve, the safety valve closes.

[0034] In this embodiment, a liquid level sensor mounting pipe 37 is fixedly installed on the outer surface of the cylinder 1. The liquid level sensor is installed on the mounting pipe 37. When the liquid level of the dye liquid entering from the inlet pipe 24 reaches the position of the liquid level sensor, the inlet pipe 24 stops feeding liquid. When it is necessary to completely release the dye liquid in the cylinder 1, the outlet pipe 25 is opened to release the dye liquid in the cylinder 1 for maintenance, internal cleaning or replacement of the dye liquid.

[0035] In this embodiment, a plurality of legs 38 are fixedly provided on the lower end face of the cylinder body 1, and the driving device includes a hydraulic telescopic rod 39 fixedly provided between the plurality of legs 38. The output end of the hydraulic telescopic rod 39 is fixedly provided with the bottom end of the central slide rod 3.

[0036] The working principle of this utility model is as follows: When in use, the cylinder cover 29 is opened by rotating the hinge rod 28, and the fabric is wound on the support rod 7; then the cylinder cover 29 is fastened to the cylinder body, and then the liquid inlet pipe 24 enters the dye liquor and stops the liquid inlet when it reaches the smoke sensor; then the hydraulic telescopic rod 39 drives the central slide rod 3 to move up and down, so that the support rod 7 drives the fabric to move up and down in the dye liquor, forming water flow that penetrates inside and outside, and dyeing evenly.
