Description

Technical Field

[0001] This utility model relates to the field of knitted fabric processing technology, specifically to a wrinkle-resistant fabric flattening device for processing composite heat-insulating and windproof knitted fabrics. Background Technology

[0002] Composite thermal insulation and windproof knitted fabric is a new type of textile material that combines thermal insulation and windproof functions, and is widely used in outdoor clothing, tents, automotive interiors, and other fields. During its processing, the fabric needs to be wound, stored, and transported before entering a flattening process to eliminate folding stress, remove surface dust and impurities, and ensure the flatness of subsequent cutting or sewing. However, the composite thermal insulation and windproof knitted fabric has characteristics such as softness, small gaps between fibers, and a tendency to attract static electricity, which places higher demands on the flattening and dust removal processes.

[0003] Patent CN221701858U discloses a fabric flattening device that uses a single-sided dust removal roller to remove dust from the fabric surface, but it has the following significant drawbacks:

[0004] The current solution can only remove dust from one side of the fabric, and the bottom side is prone to retaining fiber debris and dust due to contact with the base plate, making it impossible to effectively remove dust from the other side of the fabric. Furthermore, the solution uses a single fixed pressure roller to press down directly, which can easily cause creases due to local stress concentration during the flattening process. Therefore, there is an urgent need for a wrinkle-resistant fabric flattening device for processing composite heat-insulating and windproof knitted fabrics to solve the above problems.

[0007] (II) Technical Solution

[0008] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A wrinkle-resistant fabric flattening device for processing composite heat-insulating and windproof knitted fabric includes a support frame. A dust removal mechanism is installed inside the support frame for simultaneous double-sided dust removal of the fabric. A flattening mechanism is installed at the top of the support frame for flattening the fabric. A winding roller is installed on the back of the support frame for winding the processed fabric.

The rotating shaft of the adsorption dust removal roller extends through to one end of the support frame and is equipped with a rotary joint. One end of the rotary joint is equipped with a dual-channel conveying pipe, which is connected to the adsorption dust removal roller. The flattening mechanism includes a vertical drive cylinder fixedly installed at the top of the support frame. A lifting frame is fixedly connected to the output end of the vertical drive cylinder.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the embodiments, by Figure 1-4 This invention discloses a wrinkle-resistant fabric flattening device for processing composite heat-insulating and windproof knitted fabrics. The device includes a support frame 1, with a dust removal mechanism inside the support frame 1 for simultaneous double-sided dust removal of the fabric. The dust removal mechanism includes an adsorption dust removal roller 2 rotatably connected to the inner wall of the support frame 1 via bearings. Dust removal brushes 3 are arranged in a circular array on the outer circumference of the adsorption dust removal roller 2. Negative pressure suction holes 4 are opened inside the adsorption dust removal roller 2, distributed in the gaps between the dust removal brushes 3. A rotary joint 5 is mounted at one end of the rotating shaft of the adsorption dust removal roller 2 extending to the other side of the support frame 1. A dual-channel conveying pipe 6 is mounted at one end of the rotary joint 5, communicating with the adsorption dust removal roller 2. A winding roller 19 is provided on the back of the support frame 1 for winding up the processed fabric.

[0029] Specifically, refer to Figure 2 A motor 15 is fixedly installed on the side wall of the support frame 1. The output shaft of the motor 15 is fixedly connected to the rotating shaft of the adsorption dust removal roller 2. There are two adsorption dust removal rollers 2. The rotating shafts of the two adsorption dust removal rollers 2 are respectively fixedly connected to a first gear 16 and a second gear 17 that mesh with each other.

[0030] In this embodiment, in actual use, the motor 15 is started and the double adsorption dust removal roller 2 rotates synchronously in opposite directions through gear meshing to remove dust from the upper and lower surfaces of the fabric respectively. The first gear 16 and the second gear 17 ensure that the two rollers rotate at the same speed to avoid fabric stretching and deformation caused by speed difference.

[0031] Specifically, refer to Figure 2 A dust collection box 20 is fixedly connected to the inner bottom wall of the support frame 1. A dust removal fan 18 is fixedly installed on the side wall of the dust collection box 20. A dust filter screen is provided at the connection between the dust removal fan 18 and the dust collection box 20. One side of the dust collection box 20 is fixedly connected to the dual-channel conveying pipe 6.

[0032] In this embodiment, in actual use, the dust removal roller 2 rotates, causing the dust removal brush 3 to lift the dust on the fabric. The dust removal fan 18 delivers negative pressure to the two sets of dust removal rollers 2 through the dual-channel conveying pipe 6, causing the negative pressure suction hole 4 to generate suction, which sucks the dust swept up by the dust removal brush 3 into the dust collection box 20. The dust filter intercepts dust particles to avoid clogging the fan impeller.

[0033] Specifically, refer to Figure 3 and Figure 4 The top of the support frame 1 is provided with a flattening mechanism for flattening the fabric. The flattening mechanism includes a vertical drive cylinder 7 fixedly installed at the top of the support frame 1. A lifting frame 8 is fixedly connected to the output end of the vertical drive cylinder 7. A linkage rod 9 is rotatably connected to the bottom end of the lifting frame 8 through a pin. A flattening mounting seat 10 is rotatably connected to the end of the linkage rod 9 away from the lifting frame 8 through a pin. A flattening roller 11 is rotatably connected inside the flattening mounting seat 10 through a bearing.

[0034] Specifically, refer to Figure 4 A guide slider 12 is fixedly connected to the side wall of the flattening mounting base 10. A guide groove is provided on the inner side wall of the support frame 1. The guide slider 12 is slidably connected to the inside of the guide groove. There are two flattening rollers 11. The linkage rods 9 on the two sets of flattening mounting bases 10 are symmetrically arranged.

[0035] In this embodiment, in actual use, the guide slider 12 cooperates with the guide groove to restrict the movement of the flattening mounting seat, avoid the displacement of the linkage rod 9 due to uneven force, ensure the parallelism between the flattening roller 11 and the fabric surface, and drive the lifting frame 8 to adjust the lifting through the vertical drive cylinder 7, thereby driving the flattening mounting seat 10 to move in opposite directions through the linkage rod 9, so that the flattening roller 11 can achieve the purpose of uniform flattening.

[0036] Specifically, refer to Figure 3 A height adjustment cylinder 13 is fixedly installed on the inner bottom wall of the support frame 1, and a lifting platform 14 is fixedly connected to the output end of the height adjustment cylinder 13.

[0037] In this embodiment, in actual use, the height adjustment cylinder 13 can drive the lifting platform 14 to move vertically, so that the fabric and the pressing roller 11 fit tightly together, avoiding creases caused by looseness.

[0038] Working principle:

[0039] The operator passes the composite thermal insulation and windproof knitted fabric to be processed through the adsorption dust removal roller 2, the lifting platform 14, and finally winds it onto the take-up roller 19. The height adjustment cylinder 13 is activated to drive the lifting platform 14 to rise to the initial position, so that the fabric contacts the flattening roller 11. The motor 15 is started so that the double adsorption dust removal roller 2 rotates synchronously in opposite directions through gear meshing. The dust removal brush 3 lifts up the dust on the fabric. The dust removal fan 18 delivers negative pressure to the two sets of adsorption dust removal rollers 2 through the dual-channel conveying pipe 6, so that the negative pressure dust suction hole 4 generates suction force, and sucks the dust swept up by the dust removal brush 3 into the dust collection box 20.

[0040] The vertical drive cylinder 7 drives the lifting frame 8 to adjust its height, thereby driving the flattening mounting base 10 to move in opposite directions and away from each other through the linkage rod 9, so that the two sets of flattening rollers 11 move back and forth, without local stress concentration and wrinkling rate ≤2%.
