Description

Technical Field

[0001] The invention belongs to the technical field of goose down fabric detection, and particularly relates to a goose down fabric anti-ultraviolet aging detection device. Background Art

[0002] Velvet fabrics are all made of high-quality cotton yarn. According to the type of fabric, they can be divided into CVC80 / 20 velvet, some special velvets and chemical fiber velvets.

[0003] Among them, dense velvet is one of the important branches of chemical fiber velvet. The terry of dense velvet is FDY polyester or DTY polyester. However, in the actual use of dense velvet fabric, the anti-aging performance of dense velvet fabric has always been difficult to measure, and the performance of dense velvet fabric depends on the performance of the terry (FDY polyester).

[0004] Velvet fabrics are exposed to natural atmospheric conditions for a long time and are impacted by factors such as high light, high and low temperatures, and moisture. They will experience aging phenomena such as strength loss and color change, which will lead to a decline in performance and a shortened lifespan. Therefore, the aging resistance of velvet fabrics is receiving more and more attention from companies and users.

[0005] Among them, ultraviolet radiation is very destructive to velvet fabrics. When it is close to the light source of ultraviolet radiation, it will cause the chemical bonds of general terry fiber molecules to break. The end result is a decrease in the mechanical properties of velvet fabrics (such as strength, elongation and elasticity), and the terry fibers may even become brittle and cracked.

[0006] At present, the existing fabric anti-ultraviolet aging testing equipment includes: a test chamber, a unit (304 stainless steel inside and outside), a sample rack (aluminum alloy frame base viewing panel), a controller (color touch screen program controller or RKC intelligent controller), an irradiation lamp (A-340 or B-3138), bidirectional connection (RS232 communication interface, optional), a power supply leakage circuit breaker control circuit with short circuit alarm, temperature alarm, and water shortage protection. It uses a fluorescent ultraviolet lamp with a spectrum higher than the ultraviolet range of sunlight, and combines temperature control to prevent damage factors such as discoloration, brightness, intensity reduction, cracking, peeling, powdering, and oxidation caused by the material. At the same time, through the synergistic effect between ultraviolet light and moisture, the material's single light resistance or single moisture resistance is weakened or invalidated, and is therefore widely used to evaluate the fabric's anti-ultraviolet aging performance. The above-mentioned device has the characteristics of providing good sunlight ultraviolet simulation, low maintenance cost, easy to use, automatic operation of equipment detection control, high degree of test automation, good lighting stability, and high reproducibility of test results.

[0007] In addition, the patent with the publication number "CN215640775U" solves the technical problem of "inconvenient adjustment of the irradiation height of the artificial light source" by adopting the feature of the "height adjustment mechanism". However, due to the relatively thick surface coils of the velvet fabric, the irradiation of the artificial light source is not comprehensive, making it difficult to ensure uniform irradiation of the surface coils of the goose down fabric.

[0022] The beneficial effects of the present invention are as follows:

[0036] The following further describes the present application in detail with reference to the drawings. It is necessary to point out here that the following specific implementation manners are only used to further illustrate the present application and cannot be understood as limiting the protection scope of the present application. Those skilled in the art can make some non - essential improvements and adjustments to the present application according to the above application content.

[0037] Embodiment 1

[0038] As Figures 1 - 2As shown, a goose down fabric anti-ultraviolet aging detection device includes a detection box body 1, an RKC intelligent controller 2, a power supply, an ultraviolet projector, a protection tester, a two-way connection and an irradiation lamp 3. The detection box body 1 is provided with a detection space 4 for placing the irradiation lamp 3;

[0039] It should be noted that the test box adopts an outer frame with a size of 400mm deep × 1140mm high × 390mm wide. Before testing the anti-ultraviolet aging properties of goose down fabrics, the goose down fabrics are placed inside the test space 4 and the test conditions are as follows: temperature RT+50℃, humidity 97%RH, the distance between two adjacent groups of radiation lamps 3 is 70mm, and the irradiance is 1.0W / m 2 The temperature control method is PID self-tuning SSR control and the effective irradiation area is 900×250mm. The technical parameters of the goose down fabric are processed. The goose down fabric after irradiation by 3 irradiation lamps passes through the M284UV ultraviolet projection and protection tester and is compared with GB / T18830-2009 to detect the anti-ultraviolet aging properties of the goose down fabric.

[0040] like Figures 2 - 3 As shown, a tensioning assembly 5 for tensioning the goose down fabric is provided in the detection space 4. The tensioning assembly 5 includes a drive motor 51 and a limiting slide 52. The output end of the drive motor 51 is connected to a rotating shaft 53. A rocker 54 is provided on the rotating shaft 53. The two ends of the rocker 54 are rotatably connected to a first connecting rod 55 and a second connecting rod 56. The free ends of the first connecting rod 55 and the second connecting rod 56 are rotatably connected to a first slide 57 and a second slide 58, respectively. The first slide 57 and the second slide 58 are both provided with a clamping assembly 59 for clamping the goose down fabric.

[0041] The axis of the rotating shaft 53 is connected to the center of the rocker 54;

[0042] The first connecting rod 55 and the second connecting rod 56 are equal in length;

[0043] There are at least two limiting slide bars 52, and the limiting slide bars 52 pass through the interior of the first slide plate 57 and the second slide plate 58;

[0044] Before conducting the anti-ultraviolet aging test on the goose down fabric, the two ends of the goose down fabric are fixed to the first slide plate 57 and the second slide plate 58 respectively using the clamping assembly 59, so that the goose down fabric is stably fixed inside the testing space 4. By turning on the power of the irradiation lamp 3, the irradiation lamp 3 is irradiated on the fixed goose down fabric to conduct the anti-ultraviolet aging test on the goose down fabric;

[0045] In the process of conducting the anti-ultraviolet aging detection test on the goose down fabric, by starting the driving motor 51, interlocking occurs among the swing rod 54, the first connecting rod 55 and the second connecting rod 56, and the first slide plate 57 and the second slide plate 58 are driven to slide relatively along the direction of the limit slide rod 52;

[0046] When the first slide plate 57 and the second slide plate 58 slide outwards, the goose down fabric located on the first slide plate 57 and the second slide plate 58 will be pulled. At this time, the internal pores of the pulled goose down fabric will become larger, and the coils on the surface of the goose down fabric will be completely exposed and exposed to the irradiation of the radiation lamp tube 3, so as to realize the anti-ultraviolet aging detection test of the goose down fabric in multiple aspects.

[0047] As Figure 6 shown, it should be noted here that: the clamping component 59 includes a pressing plate 591, a threaded rod 592 is provided inside the pressing plate 591, the bottom of the threaded rod 592 penetrates through the inside of the pressing plate 591 and is connected to the inside of the first slide plate 57 and the second slide plate 58, and anti-slip pads 593 are provided on the opposite surfaces of the pressing plate 591 and the first slide plate 57 and the second slide plate 58;

[0048] As Figure 7 shown, the anti-slip pad 593 is made of silica gel and the anti-slip pad 593 is bent in a zigzag shape;

[0049] At least two groups of the threaded rods 592 are provided;

[0050] When fixing the goose down fabric, the user can pass the goose down fabric through the lower surface of the pressing plate 591, and then tighten the threaded rod 592 to make the pressing plate 591 tightly press on the first slide plate 57, and use the anti-slip pad 593 to realize the stable fixation of the goose down fabric;

[0051] A plurality of groups of rollers 6 are provided in the detection space 4, and the goose down fabric sequentially passes through the outer surfaces of adjacent rollers 6;

[0052] Among them, the goose down fabric is laid flat on the rollers 6, and a plurality of groups of rollers 6 are used to level and sort the goose down fabric, avoid wrinkles on the goose down fabric, avoid the generation of light-dark spots and low detection accuracy;

[0053] Two groups of the rollers 6 are symmetrically provided about the central axis of the detection space 4, and a lifting plate 7 for adjusting the distance between the goose down fabric and the irradiation lamp tube 3 is provided between the two groups of rollers 6. An elevating member 8 is provided at the bottom of the lifting plate 7. The elevating member 8 includes a support leg 801, and a lifting leg 802 is slidably provided inside the support leg 801, and the top end of the lifting leg 802 is connected to the lifting plate 7;

[0054] As Figure 4As shown, a driving component 9 for driving the lifting leg 802 to lift is provided on the lifting leg 802. The driving component 9 includes a worm 901 and a rotating block 905 provided at the bottom of the support leg 801. A turbine 902 is provided on the side surface of the worm 901. A driving shaft 903 is provided at the central position of the turbine 902. An extension rod 904 is provided on the driving shaft 903. A channel 906 for the rotating block 905 to pass through is provided at the free end of the extension rod 904;

[0055] As Figure 9 shown, the shaft end of the rotating shaft 53 is connected to the central position of the worm 901; on the one hand, the rotating shaft 53 drives the worm 901 and the swing rod 54 at the same time, which is energy-saving and environmentally friendly and reduces energy consumption. On the other hand, when the swing rod 54 drives the first slide plate 57 to slide outwards, at this time the extension rod 904 swings upwards, while pulling the goose down fabric, pushing the goose down fabric upwards, making the goose down fabric close to the irradiation lamp tube 3, ensuring that the goose down fabric is irradiated in all directions and ensuring the accuracy of the detection result.

[0056] A number of groups of air-permeable through-holes are provided inside the lifting disc 7;

[0057] During the rotation of the rotating shaft 53, the worm 901 is driven to rotate, and the driving shaft 903 is linked. At this time, the extension rod 904 generates a displacement longitudinally. When the extension rod 904 swings upwards, as Figure 5 shown, the support leg 801 is pushed to move upwards inside the lifting leg 802. At this time, the upward-moving lifting disc 7 presses the lower surface of the goose down fabric, driving the goose down fabric to move in the irradiation direction of the irradiation lamp tube 3, facilitating the irradiation of the surface coil of the goose down fabric in all directions;

[0058] As Figure 8 shown, when the swing rod 54 drives the first slide plate 57 to slide inwards, the extension rod 904 swings downwards. At this time, the lifting disc 7 is driven to slide downwards, the goose down fabric is in a relaxed state, and the surface of the goose down fabric rebounds and the pores shrink. While the adjacent coils retract, the goose down fabric moves away from the irradiation lamp tube 3, ensuring the elasticity of the goose down fabric after detection.

[0059] The above embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it cannot be construed as a limitation on the scope of the patent of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
