[0050] Combine the following Figures 1 to 9 Embodiments of the present invention are described.

[0051] This embodiment relates to a testing device for textile fabrics, which can realize automated testing of textile fabrics.

[0052] The testing equipment for textile fabrics in this embodiment includes:

[0053] Frame 9;

[0054] A quantitative liquid supply component 1, the quantitative liquid supply component 1 comprises a reagent bottle 111, a reagent pump 112, a liquid inlet pipe and a liquid outlet pipe 113, the reagent bottle 111 is arranged on the frame, the reagent pump 112 is arranged on the frame, the water inlet end of the reagent pump 112 is connected to the inside of the reagent bottle 111 through the liquid inlet pipe, and the water outlet end of the reagent pump 112 is connected to the liquid outlet pipe 113;

[0055] The sample cup assembly 2 comprises a cup body 21, a washing pump 22, an opener and closeer 29, a cup cover 291, and a reversing three-way valve 23; a bottom water inlet 211 is provided at the bottom end of the cup body 21, and a forward water inlet 212 and a reverse water inlet 213 are provided at the bottom side of the cup body 21, and the forward water inlet 212 and the reverse water inlet 213 are respectively located on both sides of the bottom water inlet 211; the washing pump 22 comprises a water suction port 221 and a water supply port 222, and the water suction port 221 is connected to the bottom water inlet 211; the opener and closeer 29 is arranged on the frame, and the opener and closeer 29 is used to drive the cup cover 2 91 opens or closes the upper opening of the cup body 21; the three ports of the reversing three-way valve 23 are respectively connected to the water supply port 222, the forward water inlet 212, and the reverse water inlet 213, and the reversing three-way valve 23 includes a forward connection state and a reverse connection state. In the forward connection state, the water supply port 222 is connected to the forward water inlet 212, and in the reverse connection state, the water supply port 222 is connected to the reverse water inlet 213. The number of the sample cup assemblies is multiple; the transverse movement mechanism 12 drives the liquid outlet pipe 113 to move left and right to switch to different sample cups.

[0056] The testing equipment for textile fabrics of the present invention is equipped with a quantitative liquid supply component 1 and a sample cup component. The sample of the textile fabric is placed in the sample cup, and the solution containing the reagent is placed in the reagent bottle 111. The quantitative liquid supply component 1 can quantitatively supply the solution into the cup body 21. The sample cup component cooperates with the washing pump 22 and the reversing three-way valve 23 to realize forward washing or reverse washing of the sample in the cup body 21, and automatically realizes the washing and cleaning of the textile fabric, saving manpower. At the same time, an opener and shutter 29 is also configured. Under normal conditions, the opener and shutter 29 keeps the interior of the cup body 21 closed. When the solution needs to be added to the cup body 21, the opener and shutter 29 is used to open the interior of the cup body 21, and the interior of the cup body 21 is not easily affected by the external environment.

[0057] Specifically, when in use, first put the textile fabric and the reagent into the cup body 21 and the reagent bottle 111 respectively, and then start the reagent pump 112 to supply the reagent liquid into the cup body 21 in a quantitative manner. After that, if there is water in the cup body 21 in advance, the washing pump 22 can be started to circulate the water from the bottom water inlet 211, the washing pump 22, the forward water inlet 212 or the reverse water inlet 213, thereby realizing automatic washing of the textile fabric.

[0058] In order to improve the supply accuracy of the quantitative liquid supply component 1, the test equipment further includes a weighing component and a controller, the weighing component includes a weight 131 and a weight sensor, the weight sensor is arranged at the bottom of the weight 131, and the weight 131 is located between the liquid outlet pipe 113 and the cup body 21;

[0059] The controller is connected to the weight sensor and the reagent pump 112. When there is air in the pipeline of the quantitative liquid supply component 1, the output of the reagent pump 112 will decrease when the reagent pump 112 is working, thereby reducing the accuracy of the reagent pump 112. The weighing component is used to identify whether the pipeline in the quantitative liquid supply component 1 is completely emptied. Specifically, when it is necessary to perform an emptying detection on the liquid inlet pipe and the liquid outlet pipe 113 of the quantitative liquid supply component 1, the liquid outlet pipe 113 is moved to the top of the weight 131 by the transverse movement mechanism 12, and then the reagent pump 112 is started to make the solution in the liquid outlet pipe 113 drip onto the weight 131 for weighing. While the reagent pump 112 is working, the weight on the weight 131 is detected by the weight sensor. When the reagent pump 112 is working, the weight detected by the weight sensor changes continuously, indicating that the liquid inlet pipe and the liquid outlet pipe 113 have been emptied. The emptying detection mechanism of the present invention realizes automatic emptying, and the emptying process does not require manual intervention. It also has the function of emptying confirmation, and the emptying detection is accurate.

[0060] The following example illustrates the use principle of the emptying detection mechanism: First, according to the configured inlet pipe, outlet pipe 113 and reagent pump 112, the working parameters of the reagent pump 112 can be obtained, and the speed under the working state is set according to the working parameters of the reagent pump 112 to determine the flow rate under the working state. For example, the flow rate of the reagent pump 112 under the working state is set to v=3ml / s, and the density of the solution is p=1.02g / m3. When emptying detection is required, the reagent pump 112 is started, and the reagent pump 112 draws the solution to the weight 131 through the inlet pipe and outlet pipe 113; if there is air in the inlet pipe and outlet pipe 113, then after the reagent pump 112 has worked for t seconds, the weight increase value of the weight 131 is less than pvt, and if the air in the inlet pipe and outlet pipe 113 has been completely discharged, then after the reagent pump 112 has worked for t seconds, the change value of the gravity sensor is equal to pvt. For example, after the reagent pump 112 has worked for 3 seconds, if the change value of the weight sensor is less than 9.06g, it indicates that it is not completely emptied. If the change value of the weight sensor is equal to 9.06g, it indicates that it has been completely emptied. The signal connection between the controller and the weight sensor and the reagent pump 112 belongs to the prior art. The controller transmits and exchanges signals with the weight sensor and the reagent pump 112 through a specific interface or communication protocol. This connection mode ensures that the controller can receive data from the weight sensor in real time, and controls the working state of the reagent pump 112 according to these data, thereby realizing accurate control and management of the entire system.

[0061] Specifically, the reagent pump 112 is a peristaltic pump. The peristaltic pump delivers fluid by squeezing a hose. This squeezing method can effectively prevent the fluid from directly contacting the pump body, thus avoiding the problem of fluid contamination. In addition, the peristaltic pump has a wide range of applications and can deliver fluids of various viscosities and containing solid particles. The peristaltic pump can also operate stably for high-viscosity solutions and has good adaptability.

[0062] The weighing assembly also includes a front and rear driver 132 and a second slide 133. The front and rear driver 132 is arranged on the frame. The front and rear driver 132 drives the second slide 133 to move forward and backward. The weight 131 is arranged on the second slide 133. The weight 131 is arranged below the liquid outlet pipe 113, so that when the liquid outlet pipe 113 adds solution to the sample cup, it must be moved horizontally to the outside of the weight 131. When the weighing assembly and the quantitative mechanism are integrated into one device, the weight 131 of the weighing assembly needs to occupy the lateral space of the device. The weighing assembly in this embodiment is equipped with the front and rear driver 132 and the second slide 133 to drive the weight 131 to move, which can reduce the occupation of the lateral space, transfer the occupation of the longitudinal space, and play a role in balancing the lateral space and longitudinal space of the machine.

[0063] The sample cup assembly also includes a first valve body 24, which includes a first port 241, a second port 242, and a third port 243. The first port 241 is connected to the bottom water port 211, the second port 242 is connected to a water inlet pipe 245, a water inlet valve 246 is provided on the water inlet pipe 245, and the third port 243 is connected to a water supply port 222 of the washing pump 22. The bottom water port 211 of the cup body 21 is connected to the water inlet and the water suction port 221 of the washing pump 22 through the first valve body 24, so that the cup body 21 can realize automatic water inlet and outlet.

[0064] The first valve body 24 further includes a fourth port 244, which is in communication with the outside. The fourth port 244 is in communication with the outside, so that the bottom water port 211 can also be in communication with the outside through the fourth port 244 of the first valve body 24 for drainage.

[0065] The sample cup assembly further includes a heater 25, which is fixedly connected to the cup body 21. The heater 25 can be a heating wire, a heating film or other types of heating elements, which are designed to uniformly heat the cup body 21, thereby ensuring that the temperature distribution of the sample is uniform during the heating process. The power of the heater 25 can be adjusted as needed to adapt to different types of tests and heating requirements.

[0066] Furthermore, in order to accelerate the homogenization of the solution in the sample cup assembly, the sample cup assembly also includes a stirring assembly, which includes a passive magnetic block arranged in the reagent bottle 111, a stirring motor located below the reagent bottle 111, and a driving magnetic block driven by the stirring motor, wherein the driving magnetic block is used to drive the passive magnetic block to rotate.

[0067] The working principle of the stirring assembly is based on a magnetically driven rotation mechanism. The passive magnetic block is fixed inside the reagent bottle 111, while the driving magnetic block is located below the reagent bottle 111 and is driven by the stirring motor. When the stirring motor is started, it rotates the driving magnetic block. Due to the effect of magnetic force, the passive magnetic block will rotate synchronously with the rotation of the driving magnetic block. Since the passive magnetic block is located inside the reagent bottle 111, its rotation can drive the reagents in the bottle to mix and stir. This design does not require direct contact with the reagents, thus avoiding contamination and corrosion problems. Secondly, since the passive magnetic block and the driving magnetic block are coupled by magnetic force, there is no need to directly contact the reagents during the stirring process, thereby reducing the risk of contamination, which is particularly suitable for experimental environments with high requirements for cleanliness.

[0068] In this embodiment, there are multiple groups of quantitative liquid supply components 1, and the liquid outlet ends of the liquid outlet pipes 113 of the multiple groups of quantitative liquid supply components 1 are all arranged on the tube seat 115. Each group of quantitative liquid supply components 1 corresponds to one solution, and multiple groups of quantitative liquid supply components 1 and multiple liquid outlet pipes 113 are configured to achieve quantitative addition of multiple solutions.

[0069] In this embodiment, the number of the sample cup assemblies is also multiple, and multiple sample cup assemblies can be provided to perform multiple tests simultaneously.

[0070] The transverse movement mechanism 12 is a linear module with high-precision positioning and repeatable positioning capabilities, ensuring the stability and accuracy of the equipment during transverse movement operations.

[0071] Specifically, the heater 25 is annular, and the heater 25 is clamped on the outer wall of the cup body 21. This design allows the heater 25 to evenly surround the cup body 21, thereby ensuring a more even heat distribution during the heating process. This uniform heating method helps to quickly and effectively heat the liquid in the cup to the desired temperature, while avoiding the burning of the liquid or damage to the container caused by local overheating. In addition, the annular heater 25 has a simple structure, is easy to install and maintain, and has good stability during use and is not prone to displacement or falling off.

[0072] The sample cup assembly further includes an impeller 26, which is rotatably disposed in the cup body 21, and the forward water inlet 212 and the reverse water inlet 213 are both located above the cup body 21. The rotation of the impeller 26 can effectively promote the mixing of the liquid in the cup body 21, ensuring that the sample reaches a uniform state before analysis. Through the stirring action of the impeller 26, the washing effect can be fully simulated.

[0073] The sample cup assembly also includes a filter screen 27, a shaft block 28 and a bolt. The filter screen 27 is arranged in the cup body 21. The middle part of the impeller 26 is provided with a shaft hole. The shaft block 28 includes a shaft plate 281 and a shaft column 282. The shaft column 282 passes through the shaft hole and extends to the shaft plate 281. The shaft plate 281 is located on the side of the impeller 26 facing away from the filter screen 27. The shaft hole is sleeved outside the shaft column 282. The bolt passes through the shaft column 282, the shaft plate 281 and the filter screen 27 to lock the shaft block 28 on the filter screen 27. The impeller 26 is rotatably connected to the shaft block 28. The filter screen 27 is rotatably connected to the filter screen by bolts and the shaft block 28. The rotation connection of the impeller 26 is realized by means of the hole originally included in the filter screen structure. The structure is simple and efficient. Among them, the shaft column 282 plays the role of the rotating shaft of the impeller 26, and the shaft plate 281 plays the role of limiting the separation of the filter screen 27 along the axis direction of the shaft column 282.

[0074] The quantitative liquid supply assembly 1 further includes a lifting mechanism 114 and a tube seat 115. The transverse movement mechanism 12 drives the lifting mechanism 114 to move up and down, and the lifting mechanism 114 drives the tube seat 115 to move up and down. The liquid outlet end of the liquid outlet tube 113 is fixed on the tube seat 115. By configuring the lifting mechanism 114 to drive the tube seat 115 to move downward, when adding solution to the sample cup, the liquid outlet tube 113 can be extended into the sample cup for addition, thereby reducing the splashing of droplets and further improving the accuracy of quantitative addition of reagent solution.
