Description

Technical Field

[0001] The utility model relates to the technical field of cashmere production, in particular to an antistatic detection device for cashmere fabrics. Background Art

[0002] Wool fibers are curly, elastic, highly hygroscopic, warm, and not easily soiled. They are high-grade fabrics for clothing. Although wool fibers are highly hygroscopic, due to the lipid layer structure on the surface scale layer of wool fibers, they have high hydrophobicity and a large electrostatic tendency. Therefore, when the relative humidity of the environment is below 40%, static electricity will be generated. Especially in winter when the air is relatively dry, static electricity is likely to occur.

[0003] With the research on antistatic of cashmere knitted fabrics, such as adding a conductive layer to cashmere products, etc., the technical problem of antistatic of cashmere knitted fabrics can be effectively solved. However, in the process of antistatic research and specific production, there is no rapid detection equipment for antistatic of batch cashmere knitted products. Therefore, we propose an antistatic detection device for cashmere fabrics to solve the above problems. Summary of the Utility Model

[0005] The present application provides an antistatic detection device for cashmere fabrics, including an electrostatic barrel, a first conveyor belt, and a second conveyor belt. The first conveyor belt and the second conveyor belt are connected end to end, and the first conveyor belt and the electrostatic barrel are connected end to end. The first conveyor belt is an insulating conveyor belt, the second conveyor belt is a metal conveyor belt and is grounded, and electrostatic measurement devices are installed on both the first conveyor belt and the second conveyor belt.

[0012] As can be seen from the above technical solutions, the present application provides an anti-static detection device for cashmere fabrics. When the present application is in use, a cashmere sweater is sent into an electrostatic barrel. The cashmere sweater moves downward in the electrostatic barrel and contacts the electrostatic barrel to carry static electricity, and then falls onto the first conveyor belt. The maximum static electricity of the cashmere sweater is detected by the electrostatic measurement device. The cashmere sweater enters the second conveyor belt again.

Specific implementation manners

[0024] In order to enable those skilled in the art of the present technology to better understand the technical solutions in the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings.

[0025] See Figures 1-4, an antistatic detection device for cashmere fabrics. This application is used for the rapid and batch detection of the antistatic properties of cashmere products or other knitted fabrics, including an electrostatic barrel 2, a first conveyor belt 4, and a second conveyor belt 8. The inlet and outlet ends of the electrostatic barrel 2, the first conveyor belt 4, and the second conveyor belt 8 correspond to each other, that is, the first conveyor belt 4 and the second conveyor belt 8 are connected end to end, and the first conveyor belt 4 and the electrostatic barrel 2 are connected end to end, so that the cashmere fabric passes through in the order of the electrostatic barrel 2, the first conveyor belt 4, and the second conveyor belt 8. It should be noted that the electrostatic barrel 2 of this application is inclined, and the specific inclination angle is such that the cashmere fabric can smoothly pass through the electrostatic barrel 2 and slide down. In order to measure the maximum static electricity of the cashmere fabric, the first conveyor belt 4 is an insulating conveyor belt. During the process of the cashmere fabric falling onto the first conveyor belt 4, it can briefly maintain the maximum charge. Since only one load test is performed on the cashmere fabric, the first conveyor belt 4 can be a relatively short rubber conveyor belt or an inclined plastic slide, as long as the cashmere fabric can move through the first conveyor belt 4. It should be noted that an installation position for installing an electrostatic measurement device should be provided at the edge position of the first conveyor belt 4. The second conveyor belt 8 is a metal conveyor belt and is grounded. The second conveyor belt 8 is a conveyor belt with a metal mesh surface and is grounded. When the cashmere fabric falls onto the second conveyor belt 8, it discharges naturally through the metal object. In terms of detection, electrostatic measurement devices are installed on both the first conveyor belt 4 and the second conveyor belt 8. Among them, there is one electrostatic measurement device on the first conveyor belt 4, which is used to detect the maximum static electricity of the cashmere fabric and is installed at a position close to the electrostatic barrel 2. When the cashmere fabric falls from the electrostatic barrel 2, it can detect and record the static electricity of the passing cashmere fabric. There are multiple electrostatic measurement devices on the second conveyor belt 8, which can detect the static electricity of the cashmere fabric during its movement on the second conveyor belt 8 multiple times. This process requires ensuring that the second conveyor belt 8 runs at a constant speed, that is, the installation position of the electrostatic measurement device and the moving speed of the second conveyor belt 8 can be used to detect the time when the cashmere fabric moves to this position on the second conveyor belt 8, so as to facilitate recording the static electricity of the cashmere fabric at each time node for measurement. In this application, the measurement of static electricity specifically refers to the standard of GB / T12703.1—2021 regarding the static electricity decay time and half-life of knitted fabrics.

[0026] In the present utility model, the electrostatic barrel 2 is arranged at one end of the first conveyor belt 4 through a bracket 1. Since the electrostatic barrel 2 of this application moves by gravity, it is necessary to raise it for installation.

[0027] In the present utility model, the electrostatic barrel 2 includes a metal barrel 21 and an insulating barrel 22 arranged on the metal barrel 21. Among them, the metal barrel 21 is used to release static electricity, and the insulating barrel 22 can effectively protect the metal barrel 21 from external influences, especially the influence of staff touching, and is convenient for support and installation. The metal barrel 21 is connected to an electrostatic generator 3 through a second wire 14, and the static electricity inside the metal barrel 21 is generated by the electrostatic generator 3.

[0028] In some embodiments, a plurality of protrusions 13 are provided inside the metal barrel 21, which can increase the residence time of the cashmere fabric inside the metal barrel 21, increase the contact with the cashmere fabric, and also cause the cashmere fabric to flip, further improving the power receiving area of the cashmere fabric.

[0029] In the present utility model, the static electricity measuring device includes a support frame 5 straddling the first conveyor belt 4 or the second conveyor belt 8. The support frame 5 is made of an insulating material, specifically, a plastic material can be used. The support frame 5 is fixed to the edge of the first conveyor belt 4 or the second conveyor belt 8 through an adjusting fixing block 6. During specific installation, the adjusting fixing block 6 is a U-shaped buckle or an electromagnet. When the installation point is a non-magnetic material, it can be installed on the edge of the conveyor belt by means of a U-shaped buckle. When the edge of the conveyor belt is a ferromagnetic material, an electromagnetic sticker can be selected and installed after adjusting the position. Among them, the installation method of the electromagnet is simple and fast. A metal strip 11 is installed on the top of the support frame 5, and a plurality of metal chains 7 are installed below the metal strip 11. The metal chains 7 are used to collect static electricity information. The metal chains 7 extend downward to above the conveyor belt without contacting the conveyor belt surface, and when the cashmere fabric passes by, the cashmere fabric can contact the metal chains 7. The metal strip 11 is connected to a charge collection device 9 through a first wire 10. The metal chains 7 are sent into the charge collection device 9 through the metal strip 11 and the first wire 10 to record the static electricity information. Specifically, the metal strip 11 and the metal chains 7 can be made of copper or aluminum. A plurality of charge collection devices 9 are commonly connected to a recording device 12. The information recorded by each charge collection device 9 is recorded by the recording device 12 for convenient later file inspection. During the installation process of the static electricity measuring device, when detecting the half-life of the static electricity attenuation, the static electricity measuring device installed on the second conveyor belt 8 needs to be installed at a position on the second conveyor belt 8 close to the half-life. Specifically, it can be obtained through multiple adjustments. When it is necessary to measure that the static electricity in the cashmere fabric drops to a specified value, the installation position of the static electricity measuring device is also determined through multiple measurements and debugging. Specifically, when the measured value falls between two static electricity measuring devices, the other static electricity measuring devices installed on the second conveyor belt 8 are installed between the settings of these two static electricity measuring devices, and so on, until the specific value between the two static electricity measuring devices is the minimum value. The minimum value of the distance between two static electricity measuring devices is the distance at which two adjacent metal chains 7 will not touch each other.

[0030] As can be seen from the above technical solutions, when the present application is in use, the cashmere sweater is sent into the static electricity barrel 2. The cashmere sweater moves downward in the static electricity barrel and contacts the static electricity barrel 2 to carry static electricity, and then falls onto the first conveyor belt 4. The maximum static electricity amount of the cashmere sweater is detected by the static electricity measuring device. The cashmere sweater enters the second conveyor belt 8 again. At this time, the static electricity of the cashmere sweater is released on the second conveyor belt 8, and the static electricity amount on the cashmere sweater is detected by multiple static electricity measuring devices, and the static electricity attenuation period of the cashmere sweater is detected to obtain the antistatic ability of the cashmere sweater.

The present application is intended to cover any variations, uses, or adaptations of the present application, which follow the general principles of the present application and include the common general knowledge or conventional technical means in the technical field not disclosed in the present application.

The above-described embodiments of the present application do not constitute a limitation on the protection scope of the present application.
