Lint cleaning machines have relatively high technical content and strict manufacturing precision and operation requirements. Therefore, the correct use and maintenance of lint cleaning machines is very important.
(1) Correct use of lint cleaning machine
(1) The moisture content of lint should be less than 8% during the load test of a new vehicle. Before the test, check whether the valve position of the four-way valve is correct.
(2) Start-up sequence: suction fan → licker-in → cotton feeding system → suction fan → gin. If the gin is started first, the working box should be opened, and it can be operated with load only when it is confirmed that there is no residual lint in the lint path.
(3) Observations should be made during the test run:
① Observe whether the cotton batting is uniform through the front fence;
② Open the movable panel and observe whether there are leaks and impurities sucking back; ③ Observe the wool from the rear Check whether there are flying flowers between the upper and lower brushes.
After the test run is completed, the gin should be stopped first and only when there is no remaining lint in the lint road can it be stopped. The parking sequence is reverse to the driving sequence.
(4) When new equipment starts production, cotton with a moisture content of less than 8% should be processed. After the continuous working time exceeds 200 hours, cotton with a moisture content of more than 8% can be processed.
(2) Troubleshooting of lint cleaning machine
The causes and troubleshooting methods of lint cleaning machine are shown in Table 10-3.
(3) Safety maintenance and maintenance of lint cleaning machine
(1) Care should be taken before starting the machine Check whether the components and parts are installed firmly and correctly, and whether the rotating parts are flexible, then close and lock the protective door.
(2) Motors and electrical appliances should have reliable protection devices, and a main switch should be installed. In case of emergency, the power supply and air source should be cut off immediately.
(3) Cleaning work is not allowed until the machine is stopped. When it is found that the cotton batting is uneven or there are many flowers hanging in the machine, the machine should be stopped for processing.
(4) When foreign matter enters the machine or a burnt smell is found, the machine should be shut down to prevent fire.
(5) Bearings should be cleaned and lubricating oil replaced every quarter. Clean sprockets and gears quarterly.
(6) The lickerin has a large area of inverted teeth. If the number of inverted teeth at two or more consecutive places exceeds 3,000 teeth, a new rack should be replaced.
(7) Check whether the fasteners are loose at any time. Check once a day in the first year and every 3 to 5 days in the second year. Mainly check the licker-in, brush, cotton feeding plate, and cotton feeding roller. Fastening bolt at the pin. Always check the flexibility of each adjustment part.
(8) The inside and outside of the dust cage, the debris removal knife and other parts should be cleaned once every shift to prevent stains. Open the protective cover and clean the lint once every 1 to 2 weeks. Clean the cotton seeds and cotton fibers on the licker-in once a week.
Correct use and maintenance can reduce the occurrence rate of equipment failure, reduce the number of replacements of wearing parts, and extend its service life.
