Description

Technical Field

[0001] This utility model relates to the field of wool fabric processing technology, and more specifically, to a wrinkle-resistant finishing device for wool fabrics. Background Technology

[0002] Wool spinning is the process of processing wool fibers into yarn. Wool fibers are mainly wool, but also include cashmere, rabbit hair, mohair, yak hair, and other specialty animal hairs. The wool spinning process can also be used for pure spinning, blending, and blending wool with other natural fibers. Wool fabrics, knitwear, blankets, etc., woven from pure and blended wool yarns have characteristics such as warmth, moisture absorption, elasticity, and abrasion resistance. During the production process, compression or stretching can cause wrinkles in the fabric, thus affecting the overall appearance of the wool fabric and potentially reducing its sales potential. Therefore, wrinkle-resistant finishing devices are needed.

[0003] However, currently, the anti-wrinkle finishing of wool fabrics generally uses roller pressing and stretching to flatten and prevent wrinkles. In this process of stretching and flattening, after the fabric is ironed and then stretched, stretching stripes may appear, which will cause embossing during subsequent flattening with rollers, resulting in pressed wrinkles that are difficult to remove and affect the quality of the fabric. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a wrinkle-resistant finishing device for wool fabrics to solve the problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A wrinkle-resistant finishing device for woolen fabrics includes a housing. Two driven guide rollers are fixedly connected to the top of the housing. A feed inlet for the fabric is opened at the top of the housing. Inside the housing, driven ironing rollers, elastic rollers, and stretching rollers are installed sequentially from top to bottom. Elastic elements arranged at equal intervals are movably installed on the outer side of the elastic rollers. An air blowing assembly is installed on the outer side of the housing. An atomizer communicating and cooperating with the air blowing assembly is installed inside the housing. Two side blowing mechanisms communicating and cooperating with the air blowing assembly are installed inside the housing.

[0007] As a further description of the above technical solution: the elastic component includes a semi-circular plate and a spring, one side of the semi-circular plate is hinged to the outer side of the elastic roller, and the inner side of the semi-circular plate is elastically connected to the elastic roller via the spring.

[0008] As a further description of the above technical solution: the blowing assembly includes an air pump, a three-way pipe and an outer ring pipe. The outer side of the air pump is fixedly installed to the outer side of the housing. The output end of the air pump is fixedly connected to the top end of the three-way pipe. The horizontal end of the three-way pipe extends into the interior of the housing and communicates with the input end of the atomizer. The bottom end of the three-way pipe is fixedly connected to the outer ring pipe. The outer ring pipe is sleeved onto the outer side of the housing. The side blowing mechanism communicates and cooperates with the outer ring pipe.

[0009] As a further description of the above technical solution: the side-blowing mechanism includes a diversion pipe, a solenoid valve and a nozzle array. One end of the diversion pipe extends through to the outside of the housing and is connected and fixed to the outer ring pipe. The nozzle array is fixedly installed to the other end of the diversion pipe, and the solenoid valve is fixedly connected to the outside of the diversion pipe.

[0010] As a further description of the above technical solution: the stretching roller group includes two sets of guide rollers arranged vertically, and the two sets of guide rollers are located between two sets of nozzle rows.

[0011] As a further description of the above technical solution: a discharge port is provided on the right side of the box.

[0012] Compared with existing technologies, the advantages of this utility model are:

[0013] This solution uses elastic components on the elastic roller to elastically unfold the fabric and generates slight vibrations during fabric guiding, resulting in better fabric unfolding. At the same time, it works in conjunction with the air blowing component to blow and shake the side blowing mechanism, thus preventing wrinkles during subsequent flattening. Therefore, the device has the advantages of blowing and shaking the fabric during flattening, resulting in better fabric unfolding, avoiding wrinkles, and ensuring fabric quality.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model;

[0021] Please see Figures 1-4 In this utility model, a wrinkle-resistant finishing device for woolen fabric includes a box body 1. Two driven guide rollers 2 are fixedly connected to the top of the box body 1. The top of the box body 1 has an inlet 3 for entering the fabric. Inside the box body 1, from top to bottom, driven ironing rollers 4, elastic rollers 5 and stretching roller group 6 are installed in sequence. Elastic elements 7 are movably installed on the outer side of the elastic rollers 5 at equal intervals. An air blowing assembly 8 is installed on the outer side of the box body 1. An atomizer 9 that communicates and cooperates with the air blowing assembly 8 is installed inside the box body 1. Two side blowing mechanisms 10 that communicate and cooperate with the air blowing assembly 8 are installed inside the box body 1.

[0022] In this invention, the housing 1 serves as the main body of the device. During use, the fabric is first guided through two guide rollers 2 and into the housing 1 via the feed inlet 3. It then passes through the outer sides of the ironing roller 4 and elastic roller 5, then through the stretching roller group 6, and finally exits from the outside of the housing 1, allowing the fabric to pass through the internal path of the housing 1. The ironing roller 4, elastic roller 5, and stretching roller group 6 are then activated to rotate, transmitting the fabric. The fabric continuously enters the housing 1 via the guide rollers 2, is then ironed by the ironing roller 4, stretched and shaken by the elastic roller 5, and finally stretched and flattened by the stretching roller group 6 before being output. During the stretching process of the stretching roller group 6, the air blowing assembly 8 is activated to atomize the fabric. The mist 9 blows onto the fabric to increase humidity, and the two side blowing mechanisms 10 alternately open, blowing from both sides to stretch the fabric by the stretching roller group 6, and then blowing and shaking it to avoid vertical lines. This achieves the advantages of the device in blowing and shaking the fabric while it is flattening, resulting in better fabric unfolding, avoiding wrinkles, and ensuring fabric quality. It solves the problem that in the existing technology of anti-wrinkle finishing of wool fabrics, which generally uses roller pressing and stretching for flattening and wrinkle prevention, stretching stripes may appear after the fabric is ironed and stretched during the stretching and flattening process. This can cause pressure lines during subsequent flattening by the pressure rollers, resulting in pressed wrinkles that are difficult to remove and affect fabric quality.

[0023] Please see Figure 2The elastic element 7 includes a semi-circular plate 71 and a spring 72. One side of the semi-circular plate 71 is hinged to the outside of the elastic roller 5, and the inside of the semi-circular plate 71 is elastically connected to the elastic roller 5 via the spring 72.

[0024] In this invention, during the rotation of the elastic roller 5, the semicircular plate 71 extends and stretches the spring 72 under the action of centrifugal force. When the semicircular plate 71 contacts the fabric, it is pressed back to its original position, causing the spring 72 to be compressed, so as to achieve elastic stretching and unfolding of the fabric and generate a slight shaking, resulting in a better flattening effect of the fabric.

[0025] Please see Figure 1 The blowing assembly 8 includes an air pump 81, a three-way pipe 82, and an outer ring pipe 83. The outer side of the air pump 81 is fixedly installed to the outer side of the housing 1. The output end of the air pump 81 is fixedly connected to the top end of the three-way pipe 82. The horizontal end of the three-way pipe 82 passes through the interior of the housing 1 and is connected to the input end of the atomizer 9. The bottom end of the three-way pipe 82 is fixedly connected to the outer ring pipe 83. The outer ring pipe 83 is sleeved to the outer side of the housing 1. The side blowing mechanism 10 is connected and cooperates with the outer ring pipe 83.

[0026] In this utility model, by starting the air pump 81, airflow is blown into the three-way pipe 82, and the mist generated by the atomizer 9 blows onto the fabric to increase its humidity. The outer ring pipe 83 supplies air to the two side blowing mechanisms 10, so that they can achieve alternating blowing on both sides.

[0027] Please see Figure 1 and Figure 3 The side-blowing mechanism 10 includes a diversion pipe 101, a solenoid valve 102, and a nozzle array 103. One end of the diversion pipe 101 extends through to the outside of the housing 1 and is connected and fixed to the outer ring pipe 83. The nozzle array 103 is fixedly installed to the other end of the diversion pipe 101. The solenoid valve 102 is fixedly connected to the outside of the diversion pipe 101.

[0028] In this invention, the airflow from the outer ring pipe 83 is introduced through the diversion pipe 101 and blown evenly onto the fabric through the nozzle row 103. The two solenoid valves 102 are engaged and disengaged alternately to allow the nozzle rows 103 on both sides to blow the fabric alternately, causing it to shake and unfold, thus improving the flattening effect.

[0029] Please see Figure 1 The stretching roller group 6 includes two sets of guide rollers 61 arranged vertically, and the two sets of guide rollers 61 are located between the two sets of nozzle rows 103.

[0030] In this invention, two sets of guide rollers 61 guide the fabric to move vertically and stretch it to be straight, so that this part of the fabric is blown while other parts remain stable.

[0031] Please see Figure 1The right side of the box 1 has a discharge port 11.

[0032] In this invention, the flattened fabric is discharged through the discharge port 11, which facilitates the discharge process.

[0033] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
