Description

Technical Field

[0001] This utility model relates to the field of textile fiber transmittance detection technology, and in particular to a textile fiber transmittance detector. Background Technology

[0002] Textile fibers are divided into two types: natural fibers and chemical fibers. Flax, cotton yarn, and hemp rope are obtained from plants and are natural fibers. Wool and silk come from animals and are also natural fibers. There are many types of chemical fibers, such as nylon, synthetic fibers, and glass fibers. In the textile fiber manufacturing industry, the light transmittance of products needs to be tested using specialized equipment.

[0003] Patent CN211697501U discloses a textile fiber transmittance detector, comprising a housing and a detection box. The detection box is slidably connected to the housing. Two symmetrically distributed limiting components are provided on the outside of the detection box, each including a first clamping plate and a second clamping plate. In use, a connecting rod is pulled by hand to slide the movable rod upwards from within the movable rod, increasing the distance between the first and second clamping plates. The textile fiber to be tested passes through the two limiting components and the inside of the detection box, and is clamped by the first and second clamping plates, allowing it to be inspected through the detection box. After inspection, when it needs to be carried away, the screw is rotated to disengage from the slot, releasing the limiting effect on the detection box. Then, the detection box is slidably stored back into the housing, and the cover is rotated to seal the opening of the housing, completing the storage of the detection box.

[0004] Existing testing instruments cannot adjust the tension of textile fiber feeding, cannot meet the feeding requirements of textile fibers of different sizes, and are inconvenient to install textile fibers in the testing box. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing testing instruments, such as the inability to adjust the tension of textile fiber transmission, the inability to transport textile fibers of different sizes, and the inconvenience of installing textile fibers in the testing box. Therefore, this invention proposes a textile fiber transmittance testing instrument.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A textile fiber transmittance measuring instrument, comprising:

[0008] The base has two support plates symmetrically fixedly installed on its top, and each of the two support plates is provided with a textile fiber conveying mechanism.

[0009] The detection box, installed on the top of the base, is used to detect the light transmittance of textile fibers. The outer side of the detection box has a notch, and the inner wall of the notch has a wire hole for placing textile fibers.

[0010] The shielding structure is installed on the outside of the detection box and fits into the notch.

[0011] Preferably, the textile fiber conveying mechanism includes a power shaft rotatably mounted on a support plate. A drive roller is mounted on the outer end of the power shaft, and a servo motor is mounted on the outer side of the power shaft. The servo motor is mounted on the support plate, which has a slotted hole. A vertical rod is fixedly installed inside the slotted hole, and a slider is slidably mounted on the outer side of the vertical rod. A driven shaft is rotatably mounted on the slider via a bearing, and a support roller is mounted on the outer side of the driven shaft. The support roller cooperates with the drive roller. Two servo motors drive two drive rollers to rotate, and the two drive rollers, through the cooperation of the two support rollers, convey the textile fibers.

[0012] Preferably, a spring is sleeved on the outer side of the vertical rod, the bottom end of the spring is fixedly installed to the bottom inner wall of the strip hole, and the top end of the spring is fixedly installed to the bottom of the slider; the spring provides elastic force to the slider, and the slider drives the support roller to move upward through the driven shaft, and the textile fibers are pressed by the drive roller and the support roller.

[0013] Preferably, the shielding structure includes a U-shaped plate, the inner wall of which is slidably connected to the outer side of the detection box to shield the notch.

[0014] Preferably, the inner side of the U-shaped plate has two adjustment grooves, and a fixing block fixed to the outside of the detection box is slidably installed in each of the two adjustment grooves. Both fixing blocks are located above the notch, and a return spring is fixedly installed at the bottom of the fixing block. The bottom end of the return spring is fixedly installed to the bottom inner wall of the adjustment groove. Under normal circumstances, the U-shaped plate moves downward to seal the notch by the elastic force of the return spring.

[0015] The beneficial effects of the textile fiber transmittance detector described in this utility model are as follows:

[0016] This solution places textile fibers between a drive roller and a support roller, and uses a spring to provide elastic force to a slider. The slider drives the support roller to move upward via a driven shaft, and the textile fibers are pressed together by the drive roller and the support roller. Adjusting the distance between the drive roller and the support roller can accommodate the pressing and conveying of textile fibers of different sizes.

[0017] This solution pushes the U-shaped plate upwards, causing it to move away from the notch. Textile fibers are then inserted through the notch and into the wire hole. The U-shaped plate is then released to facilitate the removal and placement of textile fibers. The return spring's elasticity causes the U-shaped plate to move downwards, sealing the notch.

[0018] This invention has a simple structure. By adjusting the distance between the drive roller and the support roller, it can adapt to the pressing and conveying of textile fibers of different sizes. The notch facilitates the picking and placing of textile fibers. After the textile fibers are placed, the U-shaped plate moves downward to seal the notch, achieving the purpose of light blocking and avoiding affecting the test results. Attached Figure Description

[0025] The technical solutions in this embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this embodiment, and not all embodiments. Example 1

[0026] The following is combined Figures 1-5 This application will be described in further detail.

[0027] A textile fiber transmittance measuring instrument, comprising:

[0028] The base 1 has two support plates 5 symmetrically fixedly installed on its top, and each of the two support plates 5 is provided with a textile fiber conveying mechanism.

[0029] The detection box 2 is installed on the top of the base 1 and is used to detect the light transmittance of textile fibers. The outer side of the detection box 2 has a notch 4 and the inner wall of the notch 4 has a wire hole 3 for placing textile fibers.

[0030] The shielding structure is installed on the outside of the detection box 2 and cooperates with the notch 4.

[0031] Reference Figure 2 In this embodiment, the textile fiber conveying mechanism includes a power shaft 9, which is rotatably mounted on a support plate 5. A drive roller 6 is mounted on the outer end of the power shaft 9, and a servo motor 10 is mounted on the outer side of the power shaft 9. The servo motor 10 is mounted on the support plate 5, and a strip-shaped hole 11 is opened on the support plate 5. A vertical rod 12 is fixedly installed in the strip-shaped hole 11, and a slider 13 is slidably mounted on the outer side of the vertical rod 12. A driven shaft 15 is rotatably mounted on the slider 13 through a bearing, and a support roller 7 is mounted on the outer side of the driven shaft 15. The support roller 7 cooperates with the drive roller 6. The two servo motors 10 drive the two drive rollers 6 to rotate, and the two drive rollers 6 convey the textile fibers through the cooperation of the two support rollers 7.

[0032] Reference Figure 2 In this embodiment, a spring 14 is sleeved on the outside of the vertical rod 12. The bottom end of the spring 14 is fixedly installed on the bottom inner wall of the strip hole 11, and the top end of the spring 14 is fixedly installed on the bottom of the slider 13. The spring 14 provides elastic force to the slider 13, and the slider 13 drives the support roller 7 to move upward through the driven shaft 15. The textile fibers are pressed by the drive roller 6 and the support roller 7.

[0033] Reference Figure 3 , Figure 4 , Figure 5 In this embodiment, the shielding structure includes a U-shaped plate 17, the inner wall of which is slidably connected to the outer side of the detection box 2 to shield the notch 4.

[0034] Reference Figure 4 , Figure 5 In this embodiment, two adjustment grooves 18 are provided on the inner side of the U-shaped plate 17. A fixing block 16 fixed to the outside of the detection box 2 is slidably installed in each of the two adjustment grooves 18. Both fixing blocks 16 are located above the notch 4. A reset spring 19 is fixedly installed at the bottom of the fixing block 16. The bottom end of the reset spring 19 is fixedly installed to the bottom inner wall of the adjustment groove 18. Under normal circumstances, the U-shaped plate 17 moves downward to seal the notch 4 by the elastic force of the reset spring 19.

[0035] In operation, when in use, the detection box 2 is connected to the power supply. The two servo motors 10 are connected to the PLC controller for electrical control, which is existing technology and will not be described in detail here. First, the textile fiber is placed between the drive roller 6 and the support roller 7. The spring 14 provides elastic force to the slider 13. The slider 13 drives the support roller 7 to move upward through the driven shaft 15. The drive roller 6 and the support roller 7 compress the textile fiber. Then, the U-shaped plate 17 is pushed upward, and the U-shaped plate 17 moves away from the notch 4. The textile fiber is put into the wire hole 3 through the notch 4. Then, the U-shaped plate 17 is released. The elastic force of the return spring 19 causes the U-shaped plate 17 to move downward and seal the notch 4. Two servo motors 10 drive two drive rollers 6 to rotate. The two drive rollers 6, in conjunction with two support rollers 7, convey the textile fibers. The light transmittance of the textile fibers is detected by the detection box 2. The detection box 2 is equipped with a processor, a phototube, and a light-emitting tube. The detection principle of this solution is the same as that of a textile fiber light transmittance detector disclosed in Chinese Patent (Announcement No. CN208334197U). By turning on the computer, the light-emitting tube is lit up. The phototube receives the light signal emitted by the light-emitting tube, converts the light signal into an electrical signal, and transmits it to the computer for image rendering to complete the detection. Then, the detection report can be printed out by an external printer. Example 2

[0036] Example 2 is the same as Example 1 in the rest, except that: rubber sleeves 8 are provided on the outer sides of both the drive roller 6 and the support roller 7. The setting of two rubber sleeves 8 can improve the friction on the textile fibers and improve the stability of the textile fiber transmission. All structural shapes, sizes and materials of Example 1 are included in this application. In order to meet specific usage, they can be selected and adjusted. The attached drawings are schematic structural diagrams. The actual dimensions can be adjusted appropriately.
