Description

Technical Field

[0001] The utility model belongs to the technical field of fabric finishing equipment, and in particular relates to a processing device for increasing the durability of flame-retardant fabrics. Background Art

[0002] At present, most of the flame-retardant textile fabrics at home and abroad are made of pure cotton, cotton + polyester, cotton + nylon, and fabrics woven with aramid flame-retardant fibers after finishing to achieve flame-retardant function. The flame-retardant fabrics after finishing have the disadvantages of poor strength, not resistant to permanent washing, and poor flame retardancy of thin fabrics below 180g / m. Aramid flame-retardant fabrics have the disadvantages of high price, poor breathability, and limited color. In various high-risk and high-temperature environments, nitrile / cotton / nylon acid- and alkali-resistant flame-retardant fabrics are more suitable for various types of protective clothing from shirts to cotton jackets. They are resistant to washing and permanently flame-retardant, comfortable and breathable to wear, and can be woven with high strength, multiple colors, and various weight requirements. After finishing, the fabrics can have acid- and alkali-resistant and flame-retardant composite protection functions.

[0003] The finishing process of flame retardant fabrics generally includes: secondary singeing - desizing and scouring - mercerizing - acid and alkali resistance treatment - baking - shaping - secondary pre-shrinking. Among them, the secondary singeing process refers to the singeing treatment of the surface of the fabric to remove the short fluff on the surface.

[0004] The existing singeing device generally passes the fabric through the fire port multiple times and quickly, but the temperature near the singeing mechanism of this singeing device is relatively high, which can easily cause the problem of excessive singeing. The document with the authorization announcement number CN219621424U discloses a singeing device, including a base, the left and right sides of the front end of the top of the base are fixedly connected to support legs, the left support leg is fixedly connected to a drive motor at the upper position of the left center, the output end of the drive motor passes through and is fixedly connected to an extrusion roller, the right center position of the extrusion roller is fixedly connected to a connecting rod, the right center position of the connecting rod is fixedly connected to a gear, the left and right sides of the rear end of the top of the base are fixedly connected to first-order fixed legs, and a transition plate is fixedly connected between the two first-order fixed legs.

[0005] The working principle of the device to overcome excessive singeing is: the controller controls the gas solenoid valve to close, so that the two singeing burners stop emitting fire, thereby avoiding the problem of excessive temperature.

[0006] However, the device still has the following problems: when the fabric is transported from the first singeing port to the second singeing port by the transition roller, the second side of the fabric is in contact with the transition roller, the fluff on the surface is pressed down, and the singeing effect is poor when passing through the second singeing port.

[0032] Example 1

[0033] The present embodiment provides a processing device for increasing the durability of flame-retardant fabrics, comprising a base 11, a first singeing mechanism 12 and a second singeing mechanism 13 which are arranged on the same side end of the base 11 and in sequence from bottom to top, and a conveying roller mechanism 14 for conveying the fabric from the first singeing mechanism 12 to the second singeing mechanism 13, and a blower mechanism 2 is arranged between the first singeing mechanism 12 and the second singeing mechanism 13 for making the fluff on the second side of the fabric facing away from the first singeing mechanism 12 stand upright on the surface of the fabric.

[0034] It can be understood that the base 11 mentioned in this embodiment is a prosthesis composed of at least one bottom plate and two parallel vertical plates, and the first singeing mechanism 12, the second singeing mechanism 13 and the conveying roller structure 14 are all installed parallel to each other on the base 11. The first singeing mechanism 12, the second singeing mechanism 13 and the conveying roller structure 14 are prior art, and the electronic igniter, singeing burner, photoelectric switch, drive motor, roller body, etc. disclosed in the singeing device disclosed in the document CN219621424U can be referred to, so this embodiment will not be repeated.

[0035] It is worth noting that the two singeing structures are close to central symmetry, and the two singeing ports are oriented in opposite directions, and are used to singe the first and second surfaces of the fabric respectively. However, considering that when the first surface of the fabric is singed, the second surface is attached to the surface of the conveying roller, the fluff on the second surface of the fabric falls down, affecting the singeing effect of the second surface. Therefore, a blower mechanism 2 is provided between the first singeing mechanism 12 and the second singeing mechanism 13, which can achieve the following two effects: first, the fluff that falls down on the second surface of the fabric is blown away by the air discharged from the blower mechanism, so that the fluff stands upright on the second surface of the fabric, thereby improving the singeing effect; second, the airflow of the blower mechanism will blow away the first surface of the fabric at the same time, thereby cooling the first surface of the fabric and avoiding excessive singeing.

[0036] Example 2

[0037] This embodiment further optimizes the structure of the hair dryer mechanism on the basis of the embodiment 1, specifically including:

[0038] The blowing mechanism 2 includes a blowing box 21, two material delivery ports 22 arranged at the upper and lower ends of the blowing box 21 for allowing fabrics to pass through, a fan 23 arranged on the side end of the blowing box 21, and a blowing pipe structure 24 connected to the fan 23 and opening toward the surface of the fabric.

[0039] In this embodiment, the blowing pipe structure 24 includes an outlet pipe 241 connected to the fan 23, a hose 242 connected to the end of the outlet pipe 241 away from the fan 23, a blowing pipe 243 connected to the end of the hose 242 away from the outlet pipe 241, and a wind nozzle 244 arranged on the blowing pipe 243; the blowing box 21 is provided with an adjustment structure 25 connected to the blowing pipe 243 and used to adjust the blowing angle of the wind nozzle 244, and an air outlet 26 arranged at the side end of the blowing box 21. The blowing pipe 243 is a horizontal pipe parallel to the fabric, and there are multiple wind nozzles 244.

[0040] In this embodiment, the adjustment structure 25 includes a first connecting member 251 disposed at the upper end of the blowing pipe 243, and a second connecting member 252 disposed on the inner top wall of the blowing box 21 and hinged to the first connecting member 251. The hinged relationship between the first connecting member 251 and the second connecting member 252 is that the first connecting member 251 can rotate at any angle at the hinge point, and in the installed state, the first connecting member 251 tends to a vertical state. The specific structures of the first connecting member 251 and the second connecting member 252 are common knowledge known to those skilled in the art, so they will not be described in detail in this embodiment.

[0041] In this embodiment, the adjustment structure 25 also includes a winding roller 253 arranged on the blowing box 21, two fixed blocks 254 arranged at both ends of the blowing pipe 243, two traction ropes 255 wound around the winding roller 253 and inserted into the blowing box 21 and respectively connected to the two fixed blocks 254, a motor 256 arranged on the blowing box 21 and used to drive the winding roller 253 to rotate, and a protective box 257 arranged on the blowing box 21 and used to cover the winding roller 253 and the motor 256.

[0042] In this embodiment, in conjunction with the above-mentioned hinged structure, the traction rope 255 can adjust the angle of the blowing tube 243 under the tightening / relaxation adjustment of the winding roller 253, thereby ensuring that the air outlet angle of the air nozzle 244 is perpendicular to the fabric, ensuring the erection effect of the fluff.

[0043] In this embodiment, the adjustment structure 25 further includes a fixed pulley 258 disposed on the inner top wall of the blowing box 21 and used to adjust the direction of the traction rope 255. The fixed pulley 258 is mainly used to adjust the angle at which the traction rope 255 passes through the blowing box 21 to prevent the traction rope 255 from being excessively worn.

[0044] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
