A device for testing the fluorescent performance of a fluorescent composite fiber

Abstract

This utility model discloses a fluorescence performance testing device for fluorescent composite fibers, relating to the field of composite fiber processing technology. The device includes a fluorescence spectrophotometer. A cover plate is connected to one side of the top of the spectrophotometer via a damping shaft. A first light-shielding strip, a second light-shielding strip, and two curved grooves are respectively provided on both sides of the cover plate. Both the first and second light-shielding strips have curved grooves and curved openings on their sides near the cover plate. A first sealing strip is connected to the bottom of the first light-shielding strip. Through the arrangement of the cover plate, adsorption block, electromagnet, first light-shielding strip, and first sealing strip, the device allows the first and second light-shielding strips to rotate during the opening and closing of the cover plate. The increased width of the cover plate allows it to directly rest on the top and surface of the fluorescence spectrophotometer, rather than being embedded inside, thus avoiding structural wear. This effectively prevents structural wear and light leakage caused by an improperly closed cover plate.

Description

Technical Field

[0001] This utility model relates to the field of composite fiber processing technology, specifically to a fluorescence performance testing device for fluorescent composite fibers. Background Technology

[0002] Composite fiber fabrics are prepared using matte polyester FDY and fluorescent polyester fiber FDY (rare earth element) with added fluorescent components as raw materials through a network composite process. These composite fiber fabrics can absorb light after being exposed to light and emit fluorescence under dim conditions. They can be used to produce luminous banners, warning clothing for nighttime use, protective clothing, or creative apparel.

[0003] After the composite fiber is produced, samples need to be selected for quality inspection to confirm that the fiber strength meets the standards and that there are no toxic or harmful substances. Fluorescent composite fibers will have an additional fluorescence performance test, which mainly tests the fluorescence intensity, excitation wavelength, emission wavelength, fluorescence decay time, and fluorescence uniformity of the fluorescent composite fiber. The excitation wavelength and emission wavelength are mainly detected by a fluorescence spectrophotometer.

[0004] The cover plate of the fluorescence spectrophotometer needs to be opened and closed before and after loading and unloading. During the detection process, the cover plate must be kept closed to avoid the exchange of light between the inside and outside and affect the detection effect. After a long period of use, the side wall of the cover plate will inevitably be bumped and worn, which will increase the gap between the cover plate and the fluorescence spectrophotometer and may cause light leakage. Alternatively, if the cover plate is not closed tightly, light leakage will also occur, thus affecting the detection effect. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a fluorescence performance testing device for fluorescent composite fibers to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a fluorescence performance testing device for fluorescent composite fibers, comprising a fluorescence spectrophotometer, wherein a cover plate is connected to one side of the top of the fluorescence spectrophotometer via a damping shaft, and a first light-shielding strip, a second light-shielding strip, and two curved grooves are respectively provided on both sides of the cover plate; curved grooves and curved openings are provided on the side of the first and second light-shielding strips closest to the cover plate; a first sealing strip is connected to the bottom of the first light-shielding strip, and a second sealing strip is connected to the bottom of the second light-shielding strip, and curved openings are provided on one side of both the first and second sealing strips; an adsorption block penetrates the bottom of the cover plate, and an electromagnet is installed on the outer surface of the fluorescence spectrophotometer.

[0007] By adopting the above technical solution, the opening and closing of the cover plate drives the first and second light-shielding strips to rotate. The first and second light-shielding strips increase the width of the cover plate and directly rest on the top and surface of the fluorescence spectrophotometer. The first and second sealing strips also rest on the top and surface of the fluorescence spectrophotometer. The first and second sealing strips fill the gaps between the first and second light-shielding strips and the fluorescence spectrophotometer, thereby preventing light leakage. Furthermore, the electromagnet generates magnetic attraction to hold the adsorption block, causing the cover plate, the first and second light-shielding strips to be pressed down. This allows the first and second sealing strips to be deformed under pressure, better filling the gaps and preventing light leakage. It also prevents light leakage caused by the operator not closing the cover plate tightly. Moreover, the curved strips and curved grooves bend the joints between the first and second light-shielding strips and the cover plate. Since light travels in a straight line, this prevents light from passing through the joints between the first and second light-shielding strips and the cover plate, thus preventing light leakage. The curved opening also prevents light from passing through the joint between the first and second sealing strips.

[0008] Furthermore, the cover plate is rotatably connected to the fluorescence spectrophotometer via a damping shaft.

[0009] By adopting the above technical solution, when staff members take or place the solid sample holder containing fluorescent composite fibers, they need to rotate the cover plate to open and close it. The damping shaft prevents the cover plate from rotating downwards on its own due to gravity after it is opened, thereby avoiding injury to staff members' hands, solid sample holders, first light-shielding strips, and second light-shielding strips that may occur.

[0010] Furthermore, the adsorption block is made of iron material, and the electromagnet is positioned corresponding to the adsorption block.

[0011] By adopting the above technical solution, the electromagnet generates magnetic attraction to hold the adsorption block, which presses down the cover plate, the first light-blocking strip and the second light-blocking strip. This causes the first sealing strip and the second sealing strip to be squeezed and deformed under force to better fill the gap and prevent light leakage. It can also prevent the phenomenon of light leakage caused by the staff not closing the cover plate tightly.

[0012] Furthermore, the cross-sections of the first light-shielding strip, the second light-shielding strip, the first sealing strip, and the second sealing strip are all C-shaped, and the longitudinal sections of the first light-shielding strip, the second light-shielding strip, the first sealing strip, and the second sealing strip are all 7-shaped.

[0013] By adopting the above technical solution, the first and second light-shielding strips rotate during the opening and closing of the cover plate. The first and second light-shielding strips increase the width of the cover plate and directly rest on the top and surface of the fluorescence spectrophotometer, rather than being embedded inside the fluorescence spectrophotometer, thereby avoiding structural wear. During this process, the first and second sealing strips fill the gaps between the first and second light-shielding strips and the fluorescence spectrophotometer, thereby preventing light leakage. Furthermore, the first and second sealing strips also directly rest on the top and surface of the fluorescence spectrophotometer to avoid structural wear.

[0014] Furthermore, the curved strip is adapted to the curved groove, and the curved openings on the sides of the first light-shielding strip and the first sealing strip are adapted to the curved openings on the sides of the second light-shielding strip and the second sealing strip.

[0015] By adopting the above technical solution, the joint between the first light-shielding strip, the second light-shielding strip, and the cover plate is bent by the bend strip and the bend groove. Since light travels in a straight line, it prevents light from passing through the joint between the first light-shielding strip, the second light-shielding strip, and the cover plate, thus preventing light leakage. The bend also prevents light from passing through the joint between the first sealing strip and the second sealing strip.

[0016] Furthermore, both the first and second sealing strips are made of FKM or FFKM material.

[0017] By adopting the above technical solution, FKM has good UV resistance, which avoids accelerating the aging of the first and second sealing strips when the fluorescence spectrophotometer is working. FFKM has better UV resistance than FKM, and its UV resistance is several times that of FKM, but the cost will increase.

[0018] Furthermore, after the first and second sealing strips are polished and primed with Chemlok607, they are bonded and fixed to the polished first and second light-shielding strips respectively using Chemlok233.

[0019] By adopting the above technical solution, Chemlok's 607 primer and 233 adhesive can provide strong bonding strength for the first and second sealing strips, so as to fix the first and second sealing strips to the first and second light-shielding strips. After surface treatment such as grinding and primer, the bonding strength is further improved, effectively preventing the first and second sealing strips from peeling off.

[0020] Furthermore, a touch screen and multiple control buttons are installed on the other side of the top of the fluorescence spectrophotometer.

[0021] By adopting the above technical solution, the staff cuts a portion from the fluorescent composite fiber as a sample, cleans the surface of the fluorescent composite fiber, places it in a solid sample holder, then rotates the cover upwards and puts the solid sample holder into the fluorescence spectrophotometer. After placing it, the staff rotates the cover downwards and turns on the electromagnet. At this time, the staff can start the detection work through the touch screen and control buttons.

[0022] Furthermore, the first and second light-shielding strips are connected to the cover plate by bolts, and both the first and second light-shielding strips are detachably connected to the cover plate.

[0023] By adopting the above technical solution, when the first and second light-shielding strips are damaged by impact, and the first and second sealing strips are aged and broken, the staff first rotates the cover plate upwards, then the staff loosens and removes the bolts with a wrench. Then the staff can disassemble and replace the first light-shielding strip, the second light-shielding strip, the first sealing strip, and the second sealing strip. After the replacement is completed, the staff puts the bolts back on and tightens them, thereby limiting the position of the first and second light-shielding strips.

[0024] Furthermore, both the first and second light-shielding strips are made of PBT material.

[0025] By adopting the above technical solution, PBT has good UV resistance, which avoids accelerating the aging of the first and second light-shielding strips when the fluorescence spectrophotometer is working. It has a certain degree of elasticity and can be bent and deformed slightly without breaking, which makes it easy for staff to bend and remove them. This avoids the first and second light-shielding strips from being unable to be disassembled by pulling them out laterally due to obstructions from objects.

[0026] In summary, the present invention has the following main advantages:

[0027] This invention utilizes a cover plate, an adsorption block, an electromagnet, a first light-shielding strip, and a first sealing strip. During the opening and closing of the cover plate, the first and second light-shielding strips rotate, increasing the width of the cover plate so that it directly rests on the top and surface of the fluorescence spectrophotometer, rather than being embedded inside, thus avoiding structural wear. During this process, the first and second sealing strips fill the gaps between the first and second light-shielding strips and the fluorescence spectrophotometer, preventing light leakage. Furthermore, the first and second sealing strips directly rest on the top and surface of the fluorescence spectrophotometer to prevent structural wear. The electromagnet generates magnetic attraction to hold the adsorption block in place, pressing down the cover plate, the first and second light-shielding strips, causing them to deform under pressure and better fill the gaps to prevent light leakage. This also prevents light leakage caused by the operator not closing the cover tightly. Therefore, this invention effectively avoids structural wear and light leakage caused by an improperly closed cover. Attached Figure Description

Detailed Implementation

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The embodiments of this utility model will be described below based on its overall structure.

[0037] Example 1:

[0038] A device for testing the fluorescence properties of fluorescent composite fibers, such as Figures 1-6As shown, the spectrophotometer includes a fluorescence spectrophotometer 1. A cover plate 5 is connected to one side of the top of the fluorescence spectrophotometer 1 via a damping shaft 4. The cover plate 5 is rotatably connected to the fluorescence spectrophotometer 1 via the damping shaft 4. A first light-shielding strip 8, a second light-shielding strip 9, and two curved grooves 14 are respectively provided on both sides of the cover plate 5. Curved strips 13 and curved openings 15 are provided on the side of the first light-shielding strip 8 and the second light-shielding strip 9 near the cover plate 5. A first sealing strip 10 is connected to the bottom of the first light-shielding strip 8, and a second sealing strip 11 is connected to the bottom of the second light-shielding strip 9. Both the first sealing strip 10 and the second sealing strip 11 are made of FKM or FFKM material. After the first sealing strip 10 and the second sealing strip 11 are polished and primed with Chemlok 607, they are bonded and fixed to the polished first light-shielding strip 8 and the second light-shielding strip 9 respectively using Chemlok 233. The cross-sections of the first light-shielding strip 8, the second light-shielding strip 9, the first sealing strip 10, and the second sealing strip 11 are all C-shaped, and the longitudinal sections of the first light-shielding strip 8, the second light-shielding strip 9, the first sealing strip 10, and the second sealing strip 11 are all 7-shaped. A bend slit 15 is provided on one side of the first sealing strip 10 and the second sealing strip 11. An adsorption block 6 penetrates through the bottom of the cover plate 5, and the outer surface of the fluorescence spectrophotometer 1 is mounted with... Equipped with an electromagnet 7, the adsorption block 6 is made of iron. The electromagnet 7 and the adsorption block 6 are positioned correspondingly. During the opening and closing of the cover plate 5, the first light-shielding strip 8 and the second light-shielding strip 9 rotate. The first light-shielding strip 8 and the second light-shielding strip 9 increase the width of the cover plate 5, allowing it to directly rest on the top and surface of the fluorescence spectrophotometer 1. The first sealing strip 10 and the second sealing strip 11 also rest on the top and surface of the fluorescence spectrophotometer 1. The first sealing strip 10 and the second sealing strip 11 fill the gaps between the first light-shielding strip 8 and the second light-shielding strip 9 and the fluorescence spectrophotometer 1, thereby preventing light leakage. The electromagnet 7 generates a magnetic attraction force to hold the adsorption block 6 in place. The attached block 6 presses down the cover plate 5, the first light-shielding strip 8, and the second light-shielding strip 9, thereby causing the first sealing strip 10 and the second sealing strip 11 to be deformed under pressure, better filling the gaps and preventing light leakage. It also prevents light leakage caused by the staff not closing the cover plate 5 tightly. Furthermore, the curved strip 13 and the curved groove 14 bend the joint between the first light-shielding strip 8, the second light-shielding strip 9, and the cover plate 5. Since light travels in a straight line, it prevents light from passing through the joint between the first light-shielding strip 8, the second light-shielding strip 9, and the cover plate 5, thus preventing light leakage. The curved opening 15 prevents light from passing through the joint between the first sealing strip 10 and the second sealing strip 11.

[0039] See Figure 1In the above embodiment, a touch screen 2 and multiple control buttons 3 are respectively installed on the other side of the top of the fluorescence spectrophotometer 1. The operator cuts a portion from the fluorescent composite fiber as a sample, cleans the surface of the fluorescent composite fiber, and places it in the solid sample holder. Then, the operator rotates the cover plate 5 upward and puts the solid sample holder into the fluorescence spectrophotometer 1. After placing it, the operator rotates the cover plate 5 downward and turns on the electromagnet 7. At this time, the operator can start the detection work through the touch screen 2 and control buttons 3.

[0040] Example 2:

[0041] Based on the above embodiment one, the following settings are now implemented to facilitate the replacement of damaged structures.

[0042] See Figures 1-6 In the above embodiment, the first light-shielding strip 8 and the second light-shielding strip 9 are connected to the cover plate 5 by bolts 12. Both the first light-shielding strip 8 and the second light-shielding strip 9 are detachably connected to the cover plate 5. Both the first light-shielding strip 8 and the second light-shielding strip 9 are made of PBT material, which is reinforced with low-content glass fiber. When the first light-shielding strip 8 and the second light-shielding strip 9 are damaged by impact, or when the first sealing strip 10 and the second sealing strip 11 are aged and damaged, the operator first rotates the cover plate 5 upwards, and then the operator uses a wrench to loosen and remove the bolts 12. Then, the staff can disassemble and replace the first light-shielding strip 8, the second light-shielding strip 9, the first sealing strip 10, and the second sealing strip 11. Due to the special material properties of the first light-shielding strip 8 and the second light-shielding strip 9, they have a certain degree of elasticity and can be bent and deformed slightly without breaking. This makes it easy for the staff to bend and remove them, and avoids the first light-shielding strip 8 and the second light-shielding strip 9 from being unable to be disassembled by pulling them out laterally if there are any objects blocking them. After the replacement is completed, the staff will put the bolt 12 back in and tighten it, thereby limiting the first light-shielding strip 8 and the second light-shielding strip 9.

[0043] The implementation principle of this utility model is as follows: First, the operator cuts a portion from the fluorescent composite fiber as a sample, cleans the surface of the fluorescent composite fiber, and places it in a solid sample holder. Then, the operator rotates the cover plate 5 upwards and places the solid sample holder into the fluorescence spectrophotometer 1. After placement, the operator rotates the cover plate 5 downwards and turns on the electromagnet 7. At this time, the operator can start the detection work through the touch screen 2 and the control button 3. The working principle of the fluorescence spectrophotometer 1 is existing technology, and this technical solution will not be described in detail here.

[0044] During the opening and closing of the cover plate 5, the first light-shielding strip 8 and the second light-shielding strip 9 rotate. The first light-shielding strip 8 and the second light-shielding strip 9 increase the width of the cover plate 5, allowing it to directly rest on the top and surface of the fluorescence spectrophotometer 1. The first sealing strip 10 and the second sealing strip 11 also rest on the top and surface of the fluorescence spectrophotometer 1. The first sealing strip 10 and the second sealing strip 11 fill the gaps between the first light-shielding strip 8 and the second light-shielding strip 9 and the fluorescence spectrophotometer 1, thus preventing light leakage. Furthermore, the electromagnet 7 generates a magnetic force to hold the adsorption block 6 in place, allowing the cover plate 5, the first light-shielding strip 8, and the second light-shielding strip 9 to rotate. The light-shielding strip 9 is pressed down, which causes the first sealing strip 10 and the second sealing strip 11 to be deformed by the force to better fill the gap and prevent light leakage. It can also prevent the phenomenon of light leakage caused by the staff not closing the cover plate 5 tightly. Furthermore, the joint between the first light-shielding strip 8, the second light-shielding strip 9 and the cover plate 5 is bent by the curved strip 13 and the curved groove 14. Since light travels in a straight line, it prevents light from passing through the joint between the first light-shielding strip 8, the second light-shielding strip 9 and the cover plate 5 and causing light leakage. The curved opening 15 prevents light from passing through the joint between the first sealing strip 10 and the second sealing strip 11.

[0045] After the test is completed, the staff turns off the electromagnet 7 to stop the magnetic attraction of the adsorption block 6. Then the staff can rotate the cover plate 5 upward to remove the solid sample holder and then take the fluorescent composite fiber sample out of the solid sample holder for fluorescence performance testing of other equipment.

[0046] When the first light-shielding strip 8 and the second light-shielding strip 9 are damaged by impact, and the first sealing strip 10 and the second sealing strip 11 are aged and broken, the staff first rotates the cover plate 5 upwards, then loosens and removes the bolt 12 with a wrench. The staff can then disassemble and replace the first light-shielding strip 8, the second light-shielding strip 9, the first sealing strip 10, and the second sealing strip 11. Due to the special material properties of the first light-shielding strip 8 and the second light-shielding strip 9, they have a certain degree of elasticity and can bend and deform slightly without breaking, making it easy for the staff to bend and remove them. This avoids obstructing the first light-shielding strip 8 and the second light-shielding strip 9 from being unable to be disassembled by pulling them out laterally. After replacement, the staff puts the bolt 12 back in and tightens it, thereby limiting the position of the first light-shielding strip 8 and the second light-shielding strip 9.
