[0002] Windproof fabric refers to fabric with windproof effect. The mainstream in the market is to add coating or film treatment on the base fabric. This kind of windproof fabric can achieve zero air permeability. There is also a kind of windproof fabric with high density and extremely small pinholes, which can achieve windproof. This kind of windproof fabric cannot achieve zero air permeability. When adding a coating or film treatment to the base fabric to produce windproof fabric, during the production process of such fabric, the distribution of the coating in the whole roll of fabric will be uneven, that is, there will be differences in the thickness of the coating. In particular, when producing fabrics with a certain air permeability, the air permeability is low in the thick position and high in the thin position. In order to ensure the integrity of the whole roll of fabric, the existing fabric air permeability detection method is to cut some test samples at the head or tail of the whole roll of fabric for air permeability test.

[0028] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Example 1

[0029] See also Figure 1-Figure 7 , A windproof fabric production device includes a main frame 1, on which a support unit 11 for stably supporting the fabric and a winding roller 12 for winding the fabric are provided. The support unit 11 includes a first roller 111 and a second roller 112. The first roller 111 and the second roller 112 are consistent in size and height and are used to support the fabric produced by other equipment to form a flat plane. The winding roller 12 is located at the front end of the support unit 11 and is lower than the support unit 11. One end of the fabric is wound on the winding roller 12, so that the fabric on the support unit 11 is in a taut and flat state.

[0030] A negative pressure unit 2 is provided on the main frame 1, and the negative pressure unit 2 includes a groove cavity 21. The groove cavity 21 is provided on the main frame 1 and is located between the first roller 111 and the second roller 112. The upper end surface of the groove cavity 21 is flush with the highest points of the first roller 111 and the second roller 112, so that the fabric passes through the upper end surface of the groove cavity 21. The groove cavity 21 is evenly divided into a plurality of dust suction cavities 212. The bottom of each dust suction cavity 212 is connected to the dust removal box through a negative pressure pipe, so that each dust suction cavity 212 can perform dust suction operations, so that the groove cavity 21 acts as a dust suction port, and all the dust on the bottom surface of the fabric passing through the upper end surface is collected into the dust removal box, thereby reducing the dust content of the fabric.

[0031] The groove cavity 21 is also provided with a high-frequency vibration plate 211, and a plurality of through holes 2111 are evenly opened on the high-frequency vibration plate 211. The high-frequency vibration plate 211 performs high-frequency vibration when the equipment is working, and contacts the bottom surface of the fabric passing from above during the high-frequency vibration process, thereby shaking off the dust on the bottom surface of the fabric, and entering into the dust suction cavity 212 through the through holes 2111, and performing efficient dust removal and cleaning operations on the fabric passing through.

[0032] An air supply groove 22 is provided on the front and rear end surfaces of the dust suction chamber 212, and an adjustment plate 23 is provided on the air supply groove 22 to guide and slide in the up and down directions. An electric telescopic part is provided below the adjustment plate 23, and the electric telescopic part is controlled by the control unit of the equipment, thereby making the adjustment plate 23 move up and down on the air supply groove 22.

[0033] A pressure unit 24 is provided on the upper end surface of the dust suction chamber 212, wherein the fabric passes through the upper end surface of the dust suction chamber 212, and the bottom surface of the fabric is pressed against the pressure unit 24. At the same time, since the dust suction chamber 212 is in a negative pressure state, air passes through the fabric from the upper end surface into the dust suction chamber 212, and then presses the fabric against the pressure unit 24, so that there is a pressure value on the pressure unit 24.

[0034] When the negative pressure in the dust suction chamber 212 is a constant value, the pressure values ​​of fabrics with different air permeabilities pressed on the pressure unit 24 are different. The lower the air permeability, the larger the value, and the higher the air permeability, the smaller the value. The larger the pressure value, the greater the friction between the bottom surface of the fabric and the upper end surface of the dust suction chamber 212, which in turn affects the tightness of the wound fabric. Therefore, the pressure value needs to be maintained within a numerical range. At this time, the adjustment plate 23 needs to change the upper and lower positions to change the amount of air entering the dust suction chamber 212 from the air supply slot 22. In the initial state, the upper end surface of the adjustment plate 23 is flush with the upper end surface of the dust suction chamber 212. According to the different initial pressure values, the adjustment plate 23 is controlled to drop different distances to maintain the pressure value within the set numerical range.

[0035] By identifying the different distances that the adjustment plate 23 is lowered, the air permeability of the fabric can be inferred. At the same time, since the fabric is continuously passing through the upper end of the dust suction chamber 212, by continuously identifying the height of the adjustment plate 23, the air permeability variation range of the fabric passing through the width area of ​​the dust suction chamber 212 can be obtained, and the quality grade of the fabric can be determined.

[0036] The groove cavity 21 spans the entire cross-section of the fabric, and a plurality of dust suction cavities 212 are evenly arranged on the groove cavity 21. Then, by integrating the adjustment plate 23 in the dust suction cavity 212 with the pressure degree, the air permeability variation range of the entire fabric can be determined, and then the quality grade of the entire fabric can be determined.

[0037] A spray pipe 213 is provided on each dust suction chamber 212, and the spray pipe 213 is located in front of the pressure unit 24, that is, the fabric first passes through the pressure unit 24 and then passes through the spray pipe 213. During continuous operation, when the height change of the adjustment plate 23 exceeds the set value, that is, exceeds the qualified numerical range of the fabric, the spray pipe 213 sprays identification colorant on the bottom surface of the fabric, sprays and marks the unqualified positions, and records them in the control unit at the same time.

[0038] By spraying identification colorant on the unqualified area, the unqualified area can be traced, that is, repaired or avoided in the subsequent use of the fabric.

[0039] This equipment can complete the overall air permeability test during the process of vacuuming the fabric. The detected air permeability is the air permeability of the entire fabric, that is, a full inspection is carried out to ensure the quality and grade of the fabric. At the same time, it can avoid unqualified areas when using it to ensure that all locations used are qualified.

[0040] Its working principle or usage is as follows: The equipment is placed behind the coating equipment. After the coating is completed, the entire fabric processing is completed, and the fabric needs to be rolled and collected.

[0041] One end of the fabric is wound around the winding roller 12 , so that the fabric on the supporting unit 11 is in a taut and flat state. The winding roller 12 starts to rotate, thereby pulling the fabric to continue passing through the supporting unit 11 .

[0042] A groove cavity 21 is arranged between the first roller 111 and the second roller 112, and the fabric passes through the upper end surface of the groove cavity 21. The groove cavity 21 is evenly divided into a plurality of dust suction cavities 212. The bottom of each dust suction cavity 212 is connected to the dust removal box through a negative pressure pipe, so that each dust suction cavity 212 can perform dust suction operations, and the groove cavity 21 acts as a dust suction port to collect all the dust on the bottom surface of the fabric passing through the upper end surface into the dust removal box, thereby reducing the dust content of the fabric.

[0043] During the dust removal operation, the negative pressure value in the dust suction chamber 212 is a constant value. Therefore, the pressure values ​​of fabrics with different air permeability pressed on the pressure unit 24 are different. The lower the air permeability, the larger the value, and the higher the air permeability, the smaller the value. The larger the pressure value, the greater the friction between the bottom surface of the fabric and the upper end surface of the dust suction chamber 212, which in turn affects the tightness of the wound fabric. At the same time, the greater the friction, the fabric will rub against the groove cavity 21, generating more dust, thereby affecting the dust removal operation. Therefore, it is necessary to maintain the pressure value within a numerical range. At this time, it is necessary to adjust the plate 23 by changing the upper and lower positions, thereby changing the amount of air entering the dust suction chamber 212 from the air supply groove 22. In the initial state, the upper end surface of the adjusting plate 23 is flush with the upper end surface of the dust suction chamber 212. According to the different initial pressure values, the adjusting plate 23 is controlled to drop different distances to maintain the pressure value within the set numerical range.

[0044] By identifying the different distances that the adjustment plate 23 is lowered, the air permeability of the fabric can be inferred. At the same time, since the fabric is continuously passing through the upper end of the dust suction chamber 212, by continuously identifying the height of the adjustment plate 23, the air permeability variation range of the fabric passing through the width area of ​​the dust suction chamber 212 can be obtained, and the quality grade of the fabric can be determined.

[0045] The groove cavity 21 spans the entire cross-section of the fabric, and a plurality of dust suction cavities 212 are evenly arranged on the groove cavity 21. Then, by integrating the adjustment plate 23 in the dust suction cavity 212 with the pressure degree, the air permeability variation range of the entire fabric can be determined, and then the quality grade of the entire fabric can be determined.

[0046] A spray pipe 213 is provided on each dust suction chamber 212. When the height change of the adjustment plate 23 exceeds the set value during continuous operation, that is, exceeds the qualified numerical range of the fabric, the spray pipe 213 sprays identification colorant on the bottom surface of the fabric, sprays and marks the unqualified positions, and records them in the control unit at the same time. By spraying identification colorant on the unqualified area, the unqualified area can be traced, that is, repaired or avoided in the subsequent use of the fabric.

[0047] This equipment can complete the overall air permeability test during the process of vacuuming the fabric. The detected air permeability is the air permeability of the entire fabric, that is, a full inspection is carried out to ensure the quality and grade of the fabric. At the same time, it can avoid unqualified areas when using it to ensure that all locations used are qualified. Example 2

[0048] See also Figure 4-Figure 8 , Compared with Example 1, the difference lies in the structure of the winding roller 12. In this embodiment, there is no winding roller 12 in the main frame 1, which is the same as that of the present invention. The equipment is placed in a continuously moving fabric path, and the highest point of the support unit 11 is higher than the height of the fabric path, so that the support position of the support unit 11 is at a high position in the fabric path and is in a flat state, thereby performing dust removal operations and air permeability detection on the fabric.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
