A device for detecting the anti-ultraviolet performance of textile fabrics

Abstract

The invention relates to a textile fabric anti-ultraviolet performance testing device applied to the field of detection technology. Through the arrangement of a light-shielding component, during detection, air is firstly controlled inside the variable-rib pressure strip of the box to form "ribs" inside the variable-rib pressure strip, so that the variable-rib pressure strip is in a fixed state. Then, the dimming cover is controlled to move downward so that the lower end of the variable-rib pressure strip overlaps and misaligns with the upper surface of the upper shield, so that the fabric of the detected part is in a light-shielded state for detection. At the same time, after the detection, air can be controlled inside a plurality of variable-rib pressure strips to make the ribs disappear. At this time, the variable-rib pressure strip is in loose contact with the detected fabric, so that the friction force generated between the fabric and the variable-rib pressure strip when the fabric moves is not easy to cause damage to the fabric surface. Compared with the prior art, the anti-ultraviolet performance of the fabric can be continuously tested in a light-shielded environment without increasing the friction force on the fabric, thereby effectively reducing the error of the test result and improving the test efficiency.

Description

Technical Field

[0001] The invention relates to a device for detecting the anti-ultraviolet performance of textile fabrics, and in particular to a device for detecting the anti-ultraviolet performance of textile fabrics applied in the field of detection technology. Background Art

[0002] With the development of textile technology, various fabrics with special functions have been developed to meet special needs, such as UV-resistant fabrics, moisture-wicking fabrics, breathable fabrics, cooling fabrics or thermal insulation fabrics. Among them, UV-resistant fabrics must be repeatedly tested for their UV resistance (ultraviolet light blocking properties) during manufacturing.

[0003] According to the prior art, when testing the UV resistance of textiles, ultraviolet rays are often irradiated, and then an ultraviolet sensor is used under the fabric to detect the intensity of the ultraviolet rays. During the detection, external light often affects the test results. However, during the detection of the prior art, the influence of ambient light is generally ignored, and the test is directly exposed to ambient light, resulting in large errors in the test results. In addition, the sampling test of textile fabrics in the prior art requires manual loading and unloading of materials, resulting in poor continuity during detection and low efficiency. Summary of the invention

[0004] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the prior art ignores the influence of ambient light on the anti-ultraviolet performance detection and directly performs the detection under ambient light, resulting in large errors in the detection results.

[0005] In order to solve the above problems, the present invention provides a device for detecting the anti-ultraviolet performance of textile fabrics, comprising a base with a control chip, a column fixedly connected to the upper right end of the base, a detection top plate corresponding to the base fixedly connected to the upper end of the column, an ultraviolet light source is installed at the lower left end of the detection top plate, an ultraviolet receptor is installed at the upper end of the base, the ultraviolet light source is located directly above the ultraviolet receptor, and light-shielding components are provided outside the ultraviolet light source and the ultraviolet receptor, the light-shielding components include an upper protective cover located outside the ultraviolet light source, a lower protective cover located outside the ultraviolet receptor, and a dimming cover sleeved outside the upper protective cover, a plurality of electric slide rails are installed on the outer surface of the upper protective cover, the electric slide rails are connected to the control chip signal, the dimming cover is connected to the electric slide rails, the upper protective cover and the dimming cover are fixedly connected to the lower end of the detection top plate and the lower end of the base respectively, and two groups of material guide roller groups symmetrical about the ultraviolet receptor are also installed on the upper end of the base.

[0006] In the above-mentioned textile fabric anti-ultraviolet performance testing device, by setting up a light-shielding component, the anti-ultraviolet performance of the fabric can be continuously tested in a light-shielded condition without increasing the friction force on the fabric, thereby effectively reducing the error of the test result and improving the test efficiency.

[0007] As a further improvement of the present application, the material guide roller group includes a pressing roller and a lifting roller located on the side of the pressing roller close to the ultraviolet sensor. Two connecting rods are connected between the pressing roller and the lifting roller and the base. The two connecting rods on the pressing roller correspond to the two ends of the pressing roller respectively.

[0008] As a further improvement of the present application, the material lifting roller is higher than the pressure roller, and the highest point of the material lifting roller is higher than the highest point of the lower guard, and the height difference between the two does not exceed 5 mm. When the cloth is inspected, the cloth passes under the pressure roller and bypasses over the material lifting roller.

[0009] As a further improvement of the present application, the dimming cover is a light-proof annular structure, and the inner diameter of the dimming cover is greater than the outer diameter of the lower protective cover.

[0010] As another improvement of the present application, the light-shielding component also includes two groups of variable-rib strips fixedly connected to the lower end of the dimming cover and distributed in a circular array. The dimming cover includes a hollow air storage ring, a hollow air equalizing ring, and two intelligent air charging and discharging components fixedly connected between the hollow air storage ring and the hollow air equalizing ring. The intelligent air charging and discharging components are connected to the control chip signal in the base, and the lower end of the hollow air equalizing ring is fixedly connected with two groups of variable-rib strips distributed in a circular array, and the variable-rib strips are communicated with the interior of the hollow air equalizing ring.

[0011] As another improvement supplement of the present application, in the same group of variable reinforcement strips, the distance between each two adjacent variable reinforcement strips is smaller than the diameter of the variable reinforcement strips. In two groups of variable reinforcement strips, multiple variable reinforcement strips are staggered and distributed, and the staggered angle is half of the angle between two adjacent variable reinforcement strips.

[0012] As another improved supplement of the present application, the variable rib strip includes a forming section, a variable rib section fixedly embedded in the middle of the forming section, and a pressing arc section fixedly connected to the bottom of the forming section, and the forming section and the variable rib section are interconnected.

[0013] As another improved supplement of the present application, the shaping section is a hard-shaped lightweight structure, the pressing arc section is an elastic structure with a smooth surface, and the rib-changing section is a flexible sealing structure.

[0014] In summary, through the setting of the light-proof component, during detection, the inflation of the variable-rib strip of the box is controlled first, and then "ribs" are formed in the variable-rib strip, so that the variable-rib strip is in a fixed state, and then the dimming cover is controlled to move downward so that the lower end of the variable-rib strip and the upper surface of the upper protective cover overlap and misalign, so that the fabric of the inspected part is in a light-shielded state for detection. At the same time, after the detection, the air inside multiple variable-rib strips can be controlled to disappear, so that the ribs disappear. At this time, the variable-rib strip and the inspected fabric are in loose contact, so that the friction generated between the fabric and the variable-rib strip when moving is not easy to cause damage to the fabric surface. Compared with the existing technology, the fabric can be continuously tested for its UV resistance in a light-proof environment without increasing the friction on the fabric, thereby effectively reducing the error of the test result and improving the detection efficiency.

DETAILED DESCRIPTION

[0026] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0027] The first implementation method:

[0028] Figure 1 and Figure 2 A device for detecting the anti-ultraviolet performance of textile fabrics is shown, in which a represents the fabric to be detected, and comprises a base 1 with a control chip, a column 2 is fixedly connected to the upper right end of the base 1, a detection top plate 3 corresponding to the base 1 is fixedly connected to the upper end of the column 2, an ultraviolet light source 41 is installed at the lower left end of the detection top plate 3, an ultraviolet receptor 42 is installed at the upper end of the base 1, the ultraviolet light source 41 is located directly above the ultraviolet receptor 42, and light-shielding components are provided outside the ultraviolet light source 41 and the ultraviolet receptor 42.

[0029] The light-shielding component includes an upper protective cover 51 located outside the ultraviolet light source 41, a lower protective cover 52 located outside the ultraviolet receptor 42, and a dimming cover 53 sleeved outside the upper protective cover 51. A plurality of electric slide rails 501 are installed on the outer surface of the upper protective cover 51. The electric slide rails 501 are connected to the control chip signal, and the dimming cover 53 is connected to the electric slide rails 501. The dimming cover 53 can be controlled to move up and down outside the upper protective cover 51 by the control chip, thereby adjusting the distance between the dimming cover 53 and the detected fabric, thereby helping the light-shielding component to shield the part of the textile fabric being detected, thereby effectively avoiding the influence of ambient light on the detection results, thereby effectively improving the accuracy of the detection results. The upper protective cover 51 and the dimming cover 53 are respectively fixedly connected to the lower end of the detection top plate 3 and the lower end of the base 1. Two sets of guide rollers symmetrical about the ultraviolet receptor 42 are also installed on the upper end of the base 1.

[0030] The material guide roller group includes a nip roller 61 and a lifting roller 62 located on the side of the nip roller 61 close to the ultraviolet sensor 42. Two connecting rods are connected between the nip roller 61 and the lifting roller 62 and the base 1. The two connecting rods on the nip roller 61 correspond to the two ends of the nip roller 61, such as Figure 3During the inspection, along the direction of cloth movement, the end of the cloth first passes through the bottom of the pressing roller 61 and then crosses the upper end of the lifting roller 62, passes directly above the ultraviolet sensor 42, reaches the top of another lifting roller 62, and finally passes through the bottom of the pressing roller 61. At the same time, both ends of the cloth are connected to the electric roller shaft around which the cloth can be wound, so that the cloth can continuously pass directly above the ultraviolet sensor 42, so as to achieve continuous inspection of the cloth's resistance to ultraviolet rays. When inspection is required, the cloth can be controlled to stop moving, and then the dimming cover 53 can be controlled to move downward so that its bottom moves to below the upper end of the lower protective cover 52, that is, the ends of the two overlap and intersect from the side, so that part of the cloth is pressed against the top of the lower protective cover 52, and the area located in the lower protective cover 52 can be shielded and can be directly irradiated by the ultraviolet light source 41, so that the inspected area can be inspected under light-shielding conditions, effectively ensuring the accuracy of the inspection results.

[0031] The lifting roller 62 is higher than the pressing roller 61, and the highest point of the lifting roller 62 is higher than the highest point of the lower protective cover 52, and the height difference between the two does not exceed 5mm. When the cloth is inspected, the cloth passes under the pressing roller 61 and around the lifting roller 62, so that the two lifting rollers 62 can pass through the lower protective cover 52 without contacting the lower protective cover 52, so that the cloth is not easily affected by excessive friction when moving, and the inspected cloth is not damaged by friction.

[0032] The dimming cover 53 is a light-proof annular structure, and the inner diameter of the dimming cover 53 is larger than the outer diameter of the lower protective cover 52, so that after the dimming cover 53 moves downward, the dimming cover 53 can be offset with the lower protective cover 52 up and down, so that the shading effect is better and the accuracy of the detection result is improved.

[0033] In the above-mentioned textile fabric anti-ultraviolet performance testing device, by setting up a light-shielding component, the anti-ultraviolet performance of the fabric can be continuously tested in a light-shielded condition without increasing the friction force on the fabric, thereby effectively reducing the error of the test result and improving the test efficiency.

[0034] The second implementation method:

[0035] Based on the first embodiment, this embodiment adds a variable reinforcement strip 7 and related technical contents, and the rest is consistent with the first embodiment.

[0036] The details are as follows: Figure 4 and Figure 5 As shown, the light shielding assembly also includes two groups of multiple variable rib strips 7 fixedly connected to the lower end of the dimming cover 53 and distributed in a ring array, such as Figure 7The dimming cover 53 includes a hollow gas storage ring 531, a hollow gas equalizing ring 532 and two intelligent gas charging and discharging components 533 fixedly connected between the hollow gas storage ring 531 and the hollow gas equalizing ring 532. The intelligent gas charging and discharging components 533 are connected to the control chip signal in the base 1, and the lower end of the hollow gas equalizing ring 532 is fixedly connected with two groups of variable rib strips 7 distributed in a ring array, and the variable rib strips 7 are communicated with the inside of the hollow gas equalizing ring 532. When detection is required, the control chip can control the intelligent gas charging and discharging components 533 to inflate the inside of the hollow gas equalizing ring 532. After the gas enters the variable rib strip 7, "ribs" are formed in the variable rib strip 7 to shape the variable rib strip 7. At this time, the dimming cover 53 is controlled to move downward so that the lower end of the variable rib strip 7 contacts the fabric, and the fabric outside the lower protective cover 52 is squeezed downward, so that the anti-ultraviolet detection can be started. Fig. 9 After the detection is completed, the intelligent inflation and deflation component 533 can be controlled to automatically deflate, so that the variable reinforcement strip 7 loses the support of the gas and gradually relaxes. At this time, the contact between the variable reinforcement strip 7 and the cloth is a non-contact type, but a flexible contact. When the cloth moves, it is not easy to generate a large friction force. Therefore, in this embodiment, the cloth can be moved directly after the detection without waiting for the dimming cover 53 to move upward, thereby making the cloth anti-ultraviolet detection process more continuous and the effect better. During the movement of the cloth, the dimming cover 53 can be moved upward, so that the continuity of the cloth movement detection is not easily affected by the squeezing of the light-shielding component.

[0037] like Figure 6 In the same group of variable rib strips 7, the distance between each two adjacent variable rib strips 7 is less than the diameter of the variable rib strips 7. In the two groups of variable rib strips 7, multiple variable rib strips 7 are staggered with each other, and the staggered angle is half of the angle between two adjacent variable rib strips 7, so that the intervals between multiple variable rib strips 7 in the two groups of variable rib strips 7 are blocked by another variable rib strip 7, so that the annular structure formed by the two groups of variable rib strips 7 has good light-shielding properties, and it is not easy for gaps to leak light between two adjacent variable rib strips 7.

[0038] like Figure 8The variable rib strip 7 includes a shaping section 71, a variable rib section 72 fixedly embedded in the middle of the shaping section 71, and a pressing arc section 73 fixedly connected to the bottom of the shaping section 71. The shaping section 71 and the variable rib section 72 are interconnected. The shaping section 71 is a hard and lightweight structure, and the pressing arc section 73 is an elastic structure with a smooth surface. When the anti-ultraviolet test of the cloth is performed, the smooth and elastic pressing arc section 73 is directly in contact with the cloth, so that when it is squeezed on the cloth, it is not easy to cause damage to the cloth. The variable rib section 72 is a flexible sealing structure, so that when there is no gas support in the variable rib section 72, the whole is in a relatively loose state. At the same time, since the shaping section 71 is light in weight, it can adapt to deformation when in contact with the cloth, and it is not easy to produce conflicting squeezing with the cloth, so that when the cloth moves in non-testing conditions, it is not easy to affect the cloth.

[0039] In summary, through the setting of light-shielding components, during detection, if Figure 8 First, the box variable rib bead 7 is inflated to form "ribs" in the variable rib bead 7, so that the variable rib bead 7 is in a fixed state, and then the dimming cover 53 is controlled to move downward so that the lower end of the variable rib bead 7 overlaps and misaligns with the upper surface of the upper shield 51, so that the fabric of the detected part is in a light-shielded state, and the detection is carried out. At the same time, after the detection, if Fig. 9 , the internal deflation of multiple variable-rib strips 7 can be controlled to make the ribs disappear. At this time, the variable-rib strips 7 are in loose contact with the fabric to be tested, so that the friction generated between the fabric and the variable-rib strips 7 when the fabric moves is not easy to cause damage to the fabric surface. Compared with the prior art, the fabric can be continuously tested for its anti-ultraviolet performance in a light-proof environment without increasing the friction force on the fabric, thereby effectively reducing the error of the test result and improving the test efficiency.

[0040] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
