Description
Technical Field
[0001] The invention relates to the field of plastic detection, in particular to a continuous and gradual high polyester material performance detection system. Background Art
[0002] With the advancement of science and technology, material performance has become a bottleneck in various high-end fields. However, as we all know, the birth of new materials is full of chance. It cannot be deduced by the human brain or computer. At most, it can be guessed and speculated, which is often one-tenth of guessing plus ninety-nine percent of experiments. In order to verify the performance of a conjectured material, the material must first be proportioned, then prepared, and trimmed to a specified size before the final performance test can be carried out. Moreover, the entire process can only verify a material with a specific proportion, which is extremely inefficient. As for new materials produced by counterintuitive proportions, since people will not work hard in this direction, they can only be discovered by chance over time.
[0003] In order to solve the efficiency problem of new material performance verification, some laboratories use automatic batching equipment to prepare new materials by continuously changing a certain ratio. The material of the prepared material strip is gradual, and the material on each cross section is different, so multiple materials can be prepared at one time. The material preparation problem has been solved, but the detection technology still only has traditional means, and continuous detection cannot be performed. Only several sample points can be taken on the material strip, and each point is subjected to a set of repeated tests, which has low detection efficiency and a large workload. Summary of the invention
[0004] In view of the problem of cumbersome material performance testing of continuously gradient-changing materials in the prior art, the present invention provides a continuously gradient-changing high polyester material performance testing system, which can continuously test the light transmittance and conductivity of the material at different positions.

At the same time, the pressure head of the traditional Shore hardness testing instrument is set to multiple, so the hardness of multiple positions of the material strip can be tested at one time, which greatly improves the detection efficiency.

Setting a plurality of pressure heads can detect the hardness of multiple places at one time.
[0032] A detection method of a continuous gradient high polyester material performance detection system of this embodiment includes the following steps:
[0033] S1. Establish data conversion standard: a commonly used material is made into a material strip 2 with uniform texture and known national standard performance parameters, and the material strip 2 is fed from the front feeding wheel 3 into the dressing chamber 4. The material strip 2 is ground into a standard size after passing through the horizontal grinding wheel 401 and the vertical grinding wheel 402, and the surface is polished after passing through the horizontal polishing wheel 403 and the vertical polishing wheel 404, and then the transmittance data and the conductivity data of the material under the detection system can be obtained after passing through the transmittance tester 5 and the conductivity tester 6;
[0034] The material strip 2 is cut into a No. 1 material strip 201 and a No. 2 material strip 202 with known performance parameters after passing through a slitting knife 8. The No. 2 material strip 202 is passed through a Shore hardness tester 10 to obtain the corresponding hardness data of the material under the testing system, while the No. 1 material strip 201 is passed through a multi-point bending strength tester 11 to obtain the corresponding pressure data of the bending strength of the material at each outer support roller 1101 and inner support roller 1102; the outer support rollers 1101 are shrunk one by one from the inner circle to the outside, and the pressure data of the remaining outer support rollers 1101 and the inner support rollers 1102 after each outer support roller 1101 is shrunk are recorded, and the data are the measurement data simulating the breakage of the material strip 2 at each outer support roller 1101.
[0035] S2. Measure the data of the material to be tested:
[0036] The material strip 2 to be tested of a specific length is fed from the front feeding wheel 3 into the dressing chamber 4. The material strip 2 is ground into a standard size after passing through the horizontal grinding wheel 401 and the vertical grinding wheel 402. The surface is polished after passing through the horizontal polishing wheel 403 and the vertical polishing wheel 404. Then, the light transmittance data and the conductive performance data of different positions of the material strip 2 can be obtained after passing through the light transmittance detector 5 and the conductive performance tester 6.
[0037] These positions of the material strip 2 are simultaneously cut into two No. 1 material strip 201 and No. 2 material strip 202 with the same performance parameters after passing through the slitting knife 8. The No. 2 material strip 202 is passed through the Shore hardness tester 10 to measure the hardness data of these positions of the material strip 2, and the No. 1 material strip 201 is passed through the multi-point bending strength tester 11 to simultaneously measure the corresponding pressure data of these positions at each outer support roller 1101 and the inner support roller 1102; if the No. 1 material strip 201 breaks during the measurement process, the break position is calculated based on the pressure change of the outer support roller 1101, and then the pressure data of each outer support roller 1101 and the inner support roller 1102 after the No. 1 material strip 201 breaks are continuously recorded.
[0038] S3, data comparison and conversion: the transmittance data, electrical performance data, hardness data and corresponding pressure data at each outer layer support roller 1101 and inner layer support roller 1102 of the same position of the material strip 2 to be tested obtained in S2 are compared with the corresponding data of the material with known performance parameters in S1 under the detection system, so as to convert the transmittance, electrical conductivity parameters, hardness and bending strength of the material strip 2 to be tested at this position under the national standard;
[0039] If the No. 1 dividing strip 201 divided from the material strip 2 to be tested is broken, the outer support roller 1101 and the inner support roller 1102 after the break will be contracted, and if the data measured by the outer support roller 1101 and the inner support roller 1102 after the No. 1 dividing strip 201 belongs to before the break, then the data will be compared and converted with the corresponding data measured before the simulated break in S1; if the data measured by the outer support roller 1101 and the inner support roller 1102 after the No. 1 dividing strip 201 belongs to after the break, then the data will be compared and converted with the corresponding data measured after the simulated break in S1. All the above data processing and conversion processes are completed by computer, and the user only needs to analyze and use the final conversion result.
[0040] Example 2
[0041] A continuous gradient high polyester material performance detection system of the present embodiment has the same basic structure as that of embodiment 1, except that: by detecting and recording the detection data of a large number of known materials in the detection system, these data are formed into a public database. If a user needs to detect a section of continuous gradient material and hopes to obtain the most ideal raw material ratio therefrom, firstly, the data of the material to be tested is measured according to the method of step S2 in embodiment 1, and then the data is uploaded to a computer, which compares the data with the data in the public database, converts them into national standard data, and plots them in the same curve graph. The user can quickly find the ideal position point through the curve graph changes of each data at different positions, and the material ratio at this position is the target ratio.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
