Description

Technical Field

[0001] The invention belongs to the technical field of fabric processing, and in particular relates to a method for processing elastic fabric. Background Art

[0002] Elastic fabrics are popular because of their good elasticity, which makes it convenient for users to carry out outdoor activities and effectively protects the muscles from exerting force during stretching. Elastic fabrics include cotton-spandex jersey, rayon-spandex jersey, polyester-spandex jersey, polyester-spandex double-sided fabric, Tencel stretch plain fabric, modal stretch plain fabric and viscose stretch plain fabric. After knitting and forming, they are washed, dyed, cut and sewn together to form elastic clothing products. In the process of washing elastic fabrics, the elasticity of the elastic fabrics themselves needs to be considered, so they need to be stretched and then fully washed.

[0003] The existing patent number is CN202010872093.2, which is a high-elasticity UV-resistant polyester fabric processing process and processing device. The patent document discloses a technical solution for compacting and finishing the fabric. The patent uses a flat conveying device to transport the fabric, and the fabric is tightened by belts arranged on both sides of the fabric. The fabric is shaped by multiple circular rollers arranged at the end of the conveyor belt to prevent wrinkles and creases in the fabric during subsequent finishing. However, the finishing mechanism in the patent document is prone to detachment from the fabric during continuous rotation, and cannot maintain stable shaping of the fabric. Summary of the invention

[0004] In order to achieve the purpose of performing surface shaping treatment during the stable conveying process of the fabric, thereby improving the cleaning effect of the fabric, the present invention adopts the following technical solutions:

[0005] The present invention provides a method for processing elastic fabrics, comprising the following steps:

[0006] Step 1: Continue to unroll the rolled fabric at one end of the processing platform;

[0007] Step 2: Straighten the fabric and use airflow to penetrate the fabric to achieve a blowing process;

[0008] Step 3: Press both sides of the fabric with a bidirectional presser to make it flat;

[0009] Step 4: Rewind the fabric and package it.

[0010] The purpose of the present invention is to provide a stable conveying process for fabrics, to unfold the fabrics and to press their surfaces, so that after improving the flattening effect of the fabrics, the surface cleaning effect of the fabrics can be improved by using air flow blowing;

[0011] The steps of unfolding, flattening and blowing the fabric in the elastic fabric processing method provided by the present invention are all performed by a fabric finishing device. The initial tensioning of the fabric is achieved by means of multiple sets of roller structures on the fabric finishing device, and the fabric is flattened during stable transportation by means of a bidirectional pressing device. While reducing damage to the elastic properties of the fabric, the flattening performance of the fabric surface is increased, and the cleaning effect during the airflow blowing process is facilitated.

[0012] The fabric finishing device comprises a processing platform, a positioning frame I, an extension connection seat, a rotating roller I, a first rotating driver, a transmission belt, an unwinding roller, and a second rotating driver;

[0013] The processing platform is provided with a positioning frame I, a bidirectional pressing device and an extended connecting seat from left to right in sequence, an unwinding roller is placed on the positioning frame I, the fabric is rolled up on the unwinding roller, and a transmission disc is installed at the end of the unwinding roller;

[0014] Two extension connection seats are provided, and a plurality of rollers I are rotatably connected between the two extension connection seats. The plurality of rollers I located on the upper side are connected by two transmission belts, and the two transmission belts are respectively located on both sides of the rollers I;

[0015] Control the unfolding roller and the rotating roller I to rotate at a differential speed to achieve the tensioning of the unfolded fabric;

[0016] After the fabric is initially stretched tight, it is flattened by a bidirectional press, thereby reducing the degree of pulling on the fabric and reducing the damage to the elastic properties of the fabric, while improving the flattening effect on the surface of the fabric. Multiple pipes I are connected on the upper side of the processing platform, and air is supplied into the pipes by an air pump I, so that the airflow blows toward the unfolded and stretched fabric, thereby realizing the blowing and cleaning operation of the fabric.

The plurality of rollers Ⅰ14 form two groups, one above the other, on the extension connection seat 13. A transmission belt 16 is sleeved between the plurality of rollers Ⅰ14 located on the upper side.

[0039] A first rotary driver 15 is mounted on the extended connection seat 13, and an output shaft of the first rotary driver 15 is connected to one of the rotating rollers Ⅰ 14 located on the upper side through a coupling;

[0041] Wherein, the second rotary driver 23 and the driving wheel constitute a driving assembly;

[0042] By controlling the rotation speeds of the first rotary driver 15 and the second rotary driver 23, the unfolding roller 21 and the rotating roller I 14 are caused to rotate at differential speeds, thereby achieving tensioning of the unfolded fabric.

[0043] Reference Figure 2-7 As shown, an embodiment of the fabric finishing device used in the steps of unfolding, flattening and blowing the fabric in the elastic fabric processing method provided by the present invention is described, which performs line contact and compaction processing on the fabric by circular pressing surfaces on both sides to increase the fabric conveying stability while reducing wrinkles and creases on the fabric:

[0044] A bidirectional pressing device is installed on the processing platform 11, and the bidirectional pressing device is located between the positioning frame Ⅰ12 and the extension connection seat 13. The cloth is unfolded from the unfolding roller 21, passes through the bidirectional pressing device, and enters between the multiple rotating rollers Ⅰ14;

[0045] The bidirectional clamp includes a positioning frame II 17 and two clamps 31 rotatably connected to the positioning frame II 17. A transmission wheel 32 is fixedly connected to the clamp 31. The two transmission wheels 32 are connected by meshing transmission.

[0046] A third rotary driver is installed on the processing platform 11, and a driving gear is installed on the output shaft of the third rotary driver. The driving gear is connected to the single transmission wheel 32 through meshing transmission.

[0047] The fabric passes through the two pressers 31, and each presser 31 is slidably connected with a plurality of single-side pressing strips 41. A spring is fixedly connected between the presser 31 and the single-side pressing strip 41, and the spring drives the single-side pressing strip 41 to tighten on the presser 31;

[0048] In this state, the elastic pads 1 respectively installed on the outside of the presser 31 and the single-sided pressing strip 41 form a circular pressing surface, and the circular pressing surfaces on both sides are used to perform line contact pressing on the fabric, thereby increasing the fabric conveying stability and reducing wrinkles and folds on the fabric;

[0052] The control board 52 can be driven to slide on the sliding frame 51 by hydraulic means by installing a plurality of hydraulic rods on the sliding frame 51, and connecting the movable ends of the plurality of hydraulic rods to the plurality of control boards 52 respectively;

[0053] When the control plate 52 is not in contact with the control frame 43 and the presser 31 is in normal rotation, the two circular pressing surfaces can stably convey the fabric;

[0056] Then the line contact pressing state is switched to the surface contact pressing state to realize the flattening of the fabric; in this process, the finishing state of the fabric is maintained;

[0057] When the control frame 43 loses control, the O-shaped elastic ring 42 drives the elastic pad 1 on the single-side pressing strip 41 to return to its original position, thereby re-forming a circular pressing surface.

[0068] Before the fabric is rolled up on the winding roller 22, it passes from the arc edge 72 between the lower side of the secondary pressing seat 71 and the pressing device 31 located on the upper side;
