Description

Technical Field

[0001] This utility model relates to a fabric finishing device and belongs to the field of fabric technology. Background Technology

[0002] Fabric finishing is the final and crucial step in textile processing. It uses physical, chemical, or combined physical-chemical methods to improve the appearance, feel, and shape stability of the fabric, and to endow it with special functions such as waterproofing, flame retardancy, and UV resistance.

[0003] In traditional fabric finishing, spraying (or padding) and drying are usually two separate processes that need to be completed on two independent machines. After the fabric is sprayed, it needs to be transferred to the drying equipment, which leads to low production efficiency and poor process stability.

[0004] Traditional dryers (such as drum dryers and hot air tenter machines) typically transport fabrics by pulling them with fabric clamps or guide rollers. This tension is fatal to many sensitive fabrics; knitted fabrics and elastic fabrics will be stretched, deformed, and lose their elasticity. Drying under high tension fixes the internal stress of the fibers, causing the finished product to shrink significantly during subsequent washing and become stiff and lack fluffiness.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This invention addresses the shortcomings of the prior art by providing a fabric finishing device that solves the problem of discontinuous production processes, achieves efficient integrated production, resolves the issue of tension damage to fabrics during drying, and improves fabric quality.

[0007] To solve the above technical problems, the present invention adopts the following technical solution:

[0008] The fabric finishing equipment includes a housing, inside which are a spraying chamber and a drying chamber arranged vertically. Inside the spraying chamber are a spraying guide roller, a first coating roller, a second coating roller, and a spraying exit roller arranged in a staggered manner. Spraying pipes are installed directly below the first coating roller and directly above the second coating roller. Inside the drying chamber are three layers of conveyor belts, forming a channel between adjacent conveyor belts for clamping and conveying the fabric. Ovens are installed inside the upper and middle conveyor belts, and hot air is blown downwards from the ovens.

[0009] Furthermore, the spraying chamber has a feed inlet on its side, and the drying chamber has a discharge outlet on its side, with the feed inlet and discharge outlet alternately distributed on both sides of the shell.

[0010] Furthermore, a partition is provided between the spraying chamber and the drying chamber, and the partition has clearance holes for longitudinal fabric transport.

[0011] Furthermore, the spray coating guide roller is positioned close to the feed inlet.

[0012] Furthermore, the spraying guide roller is located above the clearance hole.

[0013] Furthermore, a drying guide roller is provided below the avoidance hole. After the sprayed fabric is introduced into the drying chamber, the drying guide roller is wound in a serpentine shape around the three conveyor belts.

[0014] Furthermore, the spray nozzle is arranged in parallel with the first coating roller and the second coating roller.

[0015] Furthermore, two sets of nozzles arranged in a V-shape are installed on both sides of the spray pipe.

[0016] Furthermore, the conveyor belts are arranged horizontally, and adjacent conveyor belts rotate in opposite directions.

[0017] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0018] By integrating the spraying chamber and drying chamber into a single housing and connecting them through clearance holes, fully automated continuous production from feeding, spraying to drying and discharging is achieved, which greatly improves production efficiency and ensures the continuity and stability of the process.

[0019] The fabric is gently supported and pressed forward by a three-layer conveyor belt, remaining completely relaxed. This allows the fibers to freely shrink back to their most stable shape during the drying process, thereby greatly reducing shrinkage and maintaining and enhancing the fabric's softness and fluffiness.

[0020] It employs two independent spraying systems, enabling efficient double-sided finishing as well as flexible single-sided finishing. Different finishing agents can be used in the two spraying systems to achieve different functions on the front and back of the fabric, thus realizing double-sided multi-functional finishing.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

Detailed Implementation

[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0027] like Figures 1-3 As shown in the figure, the present invention provides a fabric finishing device, including a housing 1. Inside the housing 1, there are a spraying chamber 11 and a drying chamber 12 arranged vertically. The side of the spraying chamber 11 is provided with a feed inlet 14, and the side of the drying chamber 12 is provided with a discharge outlet 15. The feed inlet 14 and the discharge outlet 15 are alternately distributed on both sides of the housing 1.

[0028] A partition 13 is provided between the spraying chamber 11 and the drying chamber 12. The partition 13 has a clearance hole 16 for longitudinal fabric conveying. The partition 13 is provided to prevent the fabric spraying and drying processes from affecting each other.

[0029] The spraying chamber 11 is equipped with a spraying guide roller 2, a first coating roller 3, a second coating roller 4 and a spraying exit roller 5 arranged in a staggered manner. The spraying guide roller 2 is located near the feed inlet 14 and the spraying exit roller 5 is located above the clearance hole 16.

[0030] Spray pipes 6 are installed directly below the first coating roller 3 and directly above the second coating roller 4, and the spray pipes 6 are arranged parallel to the first coating roller 3 and the second coating roller 4. Two sets of nozzles with a V-shaped structure are installed on both sides of the spray pipes 6, and the nozzles are used to spray the finishing agent.

[0031] The spray pipe 6 below the first coating roller 3 is used to spray the finishing agent onto the back of the fabric, and the spray pipe 6 above the second coating roller 4 is used to spray the finishing agent onto the front of the fabric. The first coating roller 3 and the second coating roller 4 not only serve as guides for the fabric, but also, when their surfaces come into contact with the fabric, they can press and coat the freshly sprayed finishing agent evenly, ensuring that the finishing agent forms a uniform film on the fabric surface.

[0032] The drying chamber 12 is equipped with three layers of conveyor belts 8, which are arranged horizontally. The adjacent conveyor belts 8 rotate in opposite directions, and a channel for clamping and conveying fabric is formed between the adjacent conveyor belts 8.

[0033] Below the clearance hole 16, a drying guide roller 7 is provided. After the sprayed fabric is introduced into the drying chamber 12, the drying guide roller 7 is wound in a serpentine shape around the three conveyor belts 8.

[0034] The upper conveyor belt 8 has a first drying oven 9 installed inside. The first drying oven 9 can blow hot air downwards to the front of the fabric.

[0035] The middle conveyor belt 8 has a second drying oven 10 installed inside. The second drying oven 10 can blow hot air downwards to the back of the fabric.

[0036] The specific working principle of this utility model is as follows:

[0037] The fabric enters the spraying chamber 11 through the feed inlet 14, and is sprayed on the back and then the front in sequence. After being evenly sprayed, the fabric bypasses the spray guide roller 5, passes through the clearance hole 16 on the partition 13, and enters the drying chamber 12. The drying guide roller 7 receives the fabric and smoothly guides it between the upper, middle, and lower three horizontally arranged conveyor belts 8 for front drying and back drying in sequence. After drying, the fabric is sent out of the equipment through the discharge port 15, and the entire finishing process is completed.

[0038] The fabric is gently held and conveyed by the upper and lower mesh belts, rather than being forcibly pulled. The fabric is in a completely relaxed state during the drying process. The mesh belt tension-free drying can ensure that the fabric (especially knitted fabrics and elastic fabrics) is soft to the touch, dimensionally stable, and does not shrink.

[0039] This invention integrates the spraying and drying processes into one machine, realizing continuous automated production from feeding to discharging, greatly improving efficiency and reducing floor space and manual operation.

[0040] This invention employs a unique dual-spray nozzle and dual-coating roller design, which can flexibly and efficiently achieve single-sided or double-sided finishing of fabrics, and has a wide range of applications.

[0041] The above description provides examples of the preferred embodiments of this utility model. Any aspects not detailed herein are common knowledge to those skilled in the art. The scope of protection of this utility model is determined by the claims. Any equivalent modifications based on the technical teachings of this utility model are also within the scope of protection of this utility model.
