    Test conditions of high-speed swing counting machine

    Release date: 2019-11-13 Author: 數粒機,數粒機廠家,數粒機價格 Click:

    Test conditions      


    1 The temperature of the test environment should be in the range of 0 ° C to 40 ° C, and the relative humidity of the test environment should not be greater than 85%.

    2 During the test, coated tablets with a diameter of 10mm should be used as standard granules; a standard bottle volume of 100pcs per bottle; a plastic bottle with a 38mm inner diameter and a volume of 100ml as a standard packaging container.


     Dry running test After the completion of the assembly of each counting machine, a dry running test should be performed. The continuous dry running time should not be less than 1h. Check the performance of the machine and meet the requirements of 5.2 and 5.8. 6.3 Productivity test This test is performed simultaneously with the filling qualification test. After the counting machine is running normally, it is continuously filled and counted, and it works at the rated speed. It is continuously filled with 200 bottles each time for a total of five times. The filling time is recorded and the total number of filling particles is counted. Calculate the production capacity according to formula (1), which should meet the requirements of 5.4. (If the sample bottles of foreign objects, broken particles and debris caused by the counting machine itself are not counted, the sample bottles of the same batch are used instead.


    change. ) M VT = ………………………………………… (1) In the formula: V ── production capacity, unit is pcs / min; M ── total number of filled particles, unit is pcs; T── time, unit is min.


    4 Filling pass rate test The test is performed after the continuous running of the counting machine, working at the rated speed, and continuously filling 200 bottles at a time, inspecting each bottle five times in total, and calculating the filling pass rate according to formula (2), which should meet 5.5 Provisions. (If the sample bottles are not caused by the counting machine itself, foreign particles, fragments and fragments are not counted and replaced with the same batch of sample bottles.)


     Y W = 1000 × 100% …………………………………… (2) In the formula: W──filling qualified rate,%; Y——filling qualified bottles, the unit is bottle.


    5 Rejection rate test The test and filling rate test are performed simultaneously. The counting machine is carried out after continuous normal operation, and works at the rated speed. It continuously fills 200 bottles each time for a total of five times. It counts the number of bottles removed and calculates the rejection rate according to formula (3). It should meet the requirements of 5.6. (If not due to counting


    The sample bottles caused by the machine itself for foreign bodies, broken particles and debris are not counted, and they are replaced with sample bottles of the same batch. ) 1000 Q Z = × 100% …………………………………… (3) In the formula: Z ─ rejection rate,%; Q ─ the number of bottles removed, the unit is bottle.


    6 Air tightness check a) Wipe lightly around the seals of the pneumatic components with absorbent cotton and observe whether there is oil stain on the absorbent cotton, which should meet the requirements of 5.3; b) Apply soapy water to the seals of the seals of the pneumatic components, Observe whether there is air leakage, which should meet the requirements of 5.3.


    GB / T ×××× — ×××× 5


    7 Noise test During no-load operation, the noise of the counting machine is measured according to the method specified by JB / T 7232, and its noise value should meet the requirements of 5.7.


     Electrical safety test


    8.1 Use an insulation resistance meter to measure its insulation resistance in accordance with the provisions of 18.3 in GB 5226.1-2008, which shall comply with the provisions of 5.9.


    8.2 In the case of cutting off the power supply of the electrical device and obtaining a constant current from a power supply with an no-load voltage not exceeding 12V (AC or DC), and the current is equal to 1.5 times the rated current or 25A (whichever is greater), let This current alternates between the ground terminal and each easily accessible metal part. Measure the voltage drop between the ground terminal and each easily accessible metal part, and calculate the resistance value from the current and voltage drop for a total of three times.


    8.3 Use a pressure tester to perform a pressure test according to the provisions of 18.4 in GB 5226.1-2008, which shall comply with the provisions of 5.11.


    9 Safety protection inspection The safety protection device shall be checked in accordance with the provisions of 5.12.
