Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of textile, in particular to a kind of automatic test device for consumption of textile material. BACKGROUND

[0002] At present, the wear and tear performance of textile material is one of the main mechanical properties of textile material, and its consumption durability directly affects the performance and use of textile material. The main test method for wear and tear performance at present is to contact textile material with abrasive to test wear, and the wear and tear performance of textile material is evaluated by appearance evaluation or mass loss method.

[0003] However, the existing test equipment has a long test time, which affects the experimental efficiency. If the friction force of abrasive and the weight of test block are increased, although the experimental time can be reduced, the textile material can be worn out in a few wear tests, which leads to invalid test. Therefore, frequent checking is required during the test, the degree of automation is low, time and effort are consumed, and the number of invalid tests is easily increased, which affects the test accuracy and efficiency. SUMMARY

[0004] To overcome the above-mentioned shortcomings, the device sets a rotating device in the cabin and sets abrasive on the inner wall of the cabin. The textile sample is placed in the cabin, and the rotating device is rotated to make the textile sample wear under the action of the abrasive. Finally, the wear and tear performance of the textile sample is tested by the mass loss value within a certain time. The speed of the rotating device of the device can be adjusted, and the test of different unit area mass and style of textile material can be completed in a short time, which shortens the test time and improves the test efficiency.

[0005] At the same time, since the principle of the device is to test the mass loss according to the timing time, in order to ensure the accuracy of the test results, the sample should be kept in normal rotating state within the specified test time. However, during the stirring of the textile sample in the cabin, the sample is easy to stick to a certain position, at this time the sample cannot rotate normally, and manual intervention is required, which affects the work efficiency and the accuracy of the test results. Therefore, the structure of the device can avoid the sample sticking to a certain position in the cabin, reduce manual intervention, and ensure the accuracy of the test results.

[0006] In order to achieve the above purposes, the technical scheme adopted by the present application is:

[0007] The present invention discloses an automated abrasion testing device for textile materials, comprising a chamber, a rotating device, a control device, a sensor, and an alarm device. The chamber is cylindrical, with abrasive material disposed on its inner surface, and a door is located on its front side. The rotating device is rotatably mounted within the chamber and includes a rotating position and stirring elements. The rotating position is located at the center of the rotating device, and multiple stirring elements are evenly arranged around the rotating position. A first switch is provided for controlling the opening and closing of the device.

[0008] Optionally, the portion of the stir bar near the rotation position is a first portion, which is rectangular with a length of 20mm and a width of 10mm, and the portion far from the rotation position is a second portion, which includes an upper line and a lower line, both of which are arcs.

[0009] Optionally, the inner diameter of the chamber is 140mm and the depth is 70mm; the total length of the rotating device is 114mm, and there are two stirring elements 3.

[0010] Optionally, a circular rear panel is provided at the rear of the compartment, and a circular additional rear panel is provided on the circular rear panel, with the circular additional rear panel located in the first quadrant, second quadrant, and third quadrant.

[0011] Multiple sensors are respectively arranged in the first, second, third, and fourth quadrants. The diameter of the circular additional rear plate is smaller than the diameter of the rear plate. Air bands are respectively arranged on the upper left, upper right, lower left, and lower right arcs of the circular rear plate, and multiple jet holes are arranged on the air bands. A circular front plate is arranged on the hatch, and a circular additional front plate is arranged on the circular front plate. Multiple sensors are respectively arranged in the first, second, third, and fourth quadrants where the circular additional front plate is located. The diameter of the circular additional front plate is smaller than the diameter of the front plate. Air bands are respectively arranged on the upper left, upper right, lower left, and lower right arcs of the circular front plate, and multiple jet holes are arranged on the air bands.

[0012] Optionally, the airflow direction generated at the midpoint of the air belt is at an angle of 30-35 degrees to the circular rear plate and the circular front plate, respectively.

[0013] Optionally, all air bands are arc-shaped, with the arc being consistent with the arc of the circular front plate and the circular rear plate, and centered in a quarter-circle arc.

[0014] Optionally, the length of the arcuate portion of the air belt is 60-70mm.

[0015] Optionally, the test sample is pre-tested, the control device records the data during the pre-test, and according to the required accuracy, a plurality of values of the corresponding sensors before and after adhesion are extracted, and the average value is taken as the threshold value Fi. The control device analyzes and obtains the shortest time T of the air belt operation that can make the test sample separate from the adhesion state.

[0016] When the formal test is performed, the data of the sensor is transmitted to the control device, the control device calculates and analyzes the data in the four quadrants to obtain the specific value Ni of each quadrant Qi, and if the Ni value is greater than the threshold value Fi, the air belt of the corresponding quadrant Qi is started, and according to the needs, multiple air belts are started at the same time if necessary.

[0017] If (Ni-Fi) / Fi ≥20%, an alarm is given and the machine is stopped for processing;

[0018] If 10%≤(Ni-Fi) / Fi<20%, the pressure is P1 (unit: pa) and the time is T;

[0019] If 5%≤(Ni-Fi) / Fi<10%, the pressure is P2 (unit: pa) and the time is T;

[0020] If (Ni-Fi) / Fi ≤5%, the pressure is P3 (unit: pa) and the time is T;

[0021] For a test sample with a unit area mass (g / m2) ≥300, P1 is 0.34pa, P2 is 0.32pa, and P3 is 0.30pa; for a test sample with a unit area mass (g / m2) 200≤m<300, P1 is 0.32pa, P2 is 0.30pa, and P3 is 0.28pa; for a test sample with a unit area mass (g / m2) m<200, P1 is 0.28pa, and P2 and P3 are both 0.25pa.

[0022] 200, P1 is 0.28pa, and P2 and P3 are both 0.25pa.

[0023] Optionally, the rotating device is detachably installed.

[0024] Optionally, a locking device is arranged on the rotating position 2. The locking device can be an axial locking ring or an axial plug-in locking device.

[0025] Optionally, a method for using the textile material wear and tear automatic testing device includes the following steps: step 1, turning on the textile material wear and tear automatic testing device, weighing the unit area weight of the sample, and cutting the sample into a required square sample for pre-testing, confirming the threshold value Fi and the shortest time T; step 2, performing formal testing, weighing the weight of the square sample before testing, opening the hatch, installing the rotating device and the abrasive material, placing the sample into the cabin 1, closing the hatch, turning on the second switch, and starting timing, on the basis of controlling the air belt to run, ensuring that the square sample normally rotates in the cabin during the testing process; step 3, after reaching the set time, taking out the square sample, and weighing the mass of the square sample after testing; and step 4, repeating the above steps and calculating the wear and tear performance of the square sample.

[0026] The present application has the following advantages:

[0027] The device sets the rotating device in the cabin and sets the abrasive material on the inner wall of the cabin, places the textile sample into the cabin, rotates the rotating device to make the textile sample wear and tear under the action of the abrasive material, and finally tests the wear and tear performance of the textile sample by the mass loss value within a certain time. The speed of the rotating device of the device can be adjusted, and the testing of different unit area mass and style of textile materials can be completed in a short time, which shortens the testing time and improves the testing efficiency.

[0028] Since the testing method is completed in a short time, it is necessary to observe the testing process to avoid the situation that the sample does not normally rotate during the testing period. If it cannot be found in time, it will directly affect the normal value of the test, and at this time, human intervention is required to move, which affects the work efficiency and the accuracy of the test results. Therefore, the setting of the device can avoid the adhesion of the sample in the cabin at a certain position, reduce manual intervention, and ensure the accuracy of the test results.

[0029] The present application obtains the relevant data of the sensor through the control device, obtains the relevant data before and after sticking to the wall through pre-testing, extracts the threshold value and time corresponding to the sample, uses the above data as a comparison basis, performs whole-process monitoring and calculation during the testing process, starts the air belt in the region in time when the sample is likely to stick to the wall, avoids starting after sticking to the wall, causes the effective time of the test to be small, and improves the testing accuracy.

[0030] For the air belt pressure, the pressure is too small, and the effect is small, only delays the first time of sticking wall, but cannot guarantee the normal rotation in the test time; the pressure is too large, which will directly blow the sample to a certain place to stick wall, and is not conducive to the test, therefore, the position, length, pressure and direction of the air belt of the application are adapted to the test material, structure and other settings of the application.

[0031] The application is based on the wide use of textile materials, and the difference in gram weight is large, the application sets different air belt pressure parameters in different gram weight intervals, and guarantees the normal rotation of the test in the test process, and is scientific and energy-saving as much as possible.

[0032] The air belt of the device is set, the position and pressure of the air belt, the direction of the airflow, the selection of the threshold value, and the numerical value of the pressure are all matched with the size of the cabin and the rotating device of the application, the shape of the sample material, the gram weight, etc., and the overall test accuracy is improved.

[0033] Because the speed of the rotating device is large, it is easy to cause the rotating device to loosen, which affects the experimental results and also easily causes safety hazards, therefore, the rotating position is provided with a locking device. BRIEF DESCRIPTION OF DRAWINGS
