Description

Technical Field

[0001] This utility model relates to the field of dyeing and printing equipment structure technology, and in particular to an environmentally friendly dyeing and printing equipment. Background Technology

[0002] Among existing fabric dyeing processes, spray dyeing, as a relatively environmentally friendly and efficient dyeing method, has been widely used in the surface dyeing treatment of textiles. Compared with traditional dip dyeing and pad dyeing processes, spray dyeing has advantages such as less dye liquor consumption, precise dyeing positioning, and simplified process flow, and is especially suitable for processing fabrics by spraying on one side. Single-sided spray dyeing is often used in scenarios such as partial dyeing, gradient dyeing, and surface functional finishing, which can effectively reduce dye consumption, reduce energy consumption, and retain the original hand feel and breathability of the fabric to a certain extent.

[0003] However, the single-sided spray dyeing process still faces some technical bottlenecks, particularly the low dye recovery rate. Dye that does not adhere to the fabric during spraying is easily wasted, increasing dye loss and the burden of waste liquid treatment. Furthermore, existing spray dyeing equipment typically has a fixed or inflexible spraying range when processing fabrics of different widths, failing to precisely control the spraying area according to the actual fabric width. This can easily result in the spraying area being too large or too small, affecting the consistency of dyeing results and material utilization.

[0004] Therefore, there is an urgent need to develop a fabric single-sided spray dyeing equipment with more efficient dye liquor recovery and adjustable spraying range, so as to further improve the green manufacturing level and production efficiency of the printing and dyeing industry. Utility Model Content

The spray adjustment mechanism includes an input pipe and spray pipes. One side of multiple spray pipes is connected to the input pipe, and multiple evenly distributed nozzles are provided on the spray pipes. An adjustment plug is provided on the other side of the spray pipes. The adjustment plug controls the number of nozzles dispensing liquid by embedding or moving its length into or outward within the spray pipe. The collection mechanism includes a collection seat and a collection plate. The collection plate is symmetrically arranged on both sides of the collection seat to assist in receiving the dye liquid overflowing from both sides.

[0012] Preferably, the inner side of the collecting plate is arc-shaped.

[0013] Preferably, the system also includes a spray plate with guide plates connected to both sides. The guide plates are arranged in an outward arc shape and have fixing rods on both sides. The collection plate has positioning holes, and the fixing rods pass through the positioning holes and are placed between the two collection plates.

Detailed Implementation

[0023] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0024] like Figures 1 to 4 As shown, this application provides an environmentally friendly dyeing and printing device, including a housing 1. The housing 1 contains a spray adjustment mechanism and a collection mechanism. The spray adjustment mechanism includes an input pipe 21 and spray pipes 22. One side of each spray pipe 22 is connected to the input pipe 21. Each spray pipe 22 has a plurality of evenly distributed nozzles 23. An adjustment plug 24 is provided on the other side of each spray pipe 22. The adjustment plug 24 controls the number of nozzles 23 dispensing liquid by embedding or shifting its length within the spray pipe 22. The adjustment plug 24 can be adjusted by... By screwing the spray pipe 22 in or out, the insertion length of the spray pipe 22 can be adjusted, thereby controlling the liquid output range of the nozzle 23, meeting the dyeing needs of different width fabrics, achieving precise adjustment of the dye spraying range, reducing dye waste, and improving the accuracy and flexibility of the process; the collection mechanism includes a collection seat 31 and a collection plate 32. The collection plate 32 is symmetrically arranged on both sides of the collection seat 31 to assist in receiving the dye overflowing from both sides, effectively receiving the dye overflowing from both sides during the spraying process, and avoiding dye leakage and environmental pollution.

[0025] A guide block 33 is connected between the two sides of the collection plate 32. The guide block 33 is inclined inward, and the inner side of the collection plate 32 is arc-shaped. The arc-shaped structure and the inwardly inclined guide block 33 of the collection plate 32 can quickly drain and collect the overflow, reduce residue, and improve collection efficiency.

[0026] A filter plate 34 is connected to the lower end of the collection seat 31. The filter plate 34 is installed through the lower side of the box body 1 and is used for preliminary filtration of impurities in the recovered dye liquor.

[0027] The lower end of the housing 1 is equipped with a recycling bin 11 and limiting blocks 12. The limiting blocks 12 are symmetrically arranged on both sides of the lower end of the housing 1. The recycling bin 11 is fixed by embedding the limiting blocks 12 on both sides. The upper end of the recycling bin 11 has an opening 13, which corresponds to the filter plate 34. The filtered dye liquor flows directly into the recycling bin 11 for convenient centralized collection and reuse. The recycling bin 11 is fixedly installed by the limiting blocks 12 on both sides, which facilitates subsequent disassembly, cleaning and replacement.

[0028] It also includes a spray plate 41, with guide plates 42 connected to both sides of the spray plate 41. The guide plates 42 are arranged in an outward arc shape, and fixing rods 43 are provided on both sides of the guide plates 42. The collection plate 32 is provided with positioning holes 35. The fixing rods 43 pass through the positioning holes 35 and are placed between the two collection plates 32. Nuts 44 are threadedly connected to the outer side of the fixing rods 43. By cooperating with the spray plate 41 and the arc-shaped guide plates 42, the spray trajectory of the dye liquor is optimized and splashing of the sprayed liquid is prevented.

[0029] The box body 1 has an inlet 14 and an outlet 15 on both sides. Inside the box body 1, near the inlet 14 and the outlet 15, there are isolation plates 51 and guide rollers 52. The guide rollers 52 are located inside the isolation plates 51.

[0030] The input pipe 21 is provided with connecting rods 6 fixed to the upper end of the box 1 on both sides. A splash guard 7 is provided below the connecting rods 6. An auxiliary roller 8 is provided at the lower end of the splash guard 7. The splash guard 7 can effectively reduce the spread of dye liquor to non-target areas and improve the recovery efficiency of dye liquor.

[0031] The connection between the adjusting plug 24 and the spray pipe 22 is a threaded connection, which facilitates quick adjustment or replacement and improves the operability and durability of the device.

[0032] During use, the polyester fabric is introduced into the housing 1 through the feed inlet 14, and the guide roller 52 flattens and stably conveys the fabric to the spraying area. The operator screws the adjusting plug 24 in the spraying adjustment mechanism into the spraying coverage area according to the width of the polyester fabric and the dyeing requirements to avoid wasting spray.

[0033] The spraying device is activated, and the dye liquor enters the spray pipe 22 through the inlet pipe 21. It is then evenly sprayed onto one side of the polyester fabric by the nozzle 23, achieving precise single-sided dyeing. During the spraying process, some unabsorbed dye liquor overflows from both sides of the fabric, flowing along the arc-shaped collection plates 32 on both sides into the collection seat 31. Guided by the inner guide blocks 33, it finally collects on the filter plate 34. The filter plate 34 performs preliminary filtration of fiber impurities in the dye liquor, and the filtered dye liquor falls directly into the recovery box 11, achieving effective dye liquor recovery.

[0034] After spraying, the polyester fabric is conveyed out of the box 1 from the discharge port 15, and then undergoes drying, color fixing and other processes to complete the entire single-sided spray dyeing process. During the spray dyeing process, the anti-splash plate 7 prevents the dye liquor from splashing outside the equipment, and the auxiliary roller 8 ensures the stability of the fabric conveying.

[0035] This process adapts to different fabric widths by adjusting the number of nozzles 23. Unused areas of nozzles 23 are no longer sprayed, effectively reducing dye consumption. At the same time, the collection mechanism fully recovers unabsorbed dye liquor, improving dye liquor utilization and reducing waste liquor discharge. It meets the requirements of environmental protection and energy conservation, and is suitable for single-sided spray dyeing production of small to medium batches of multi-specification fabrics.
