Correct handling procedures for cans and cans
1. After the daily work, the machine operator prepares before starting the machine.
1. Pressurize the grease on the lubrication points of the sealing machine with a manual oil gun, or manually lubricate the oil, in addition to automatic oil delivery.
2. Turn the handwheel by hand before production. When turning, press the arrow mark of the turning wheel to check whether the components such as the inlet can, the lower cover, the turntable and the head are complete and normal. Check whether the operating system of the whole machine is working properly, check whether the electrical equipment is sensitive, and the lubricating part is filled with sufficient lubricating grease as required. The lubricant supplied to the tanker rotor should be a food grade lubricant.
3. After checking the normal parts, after starting the motor, it is still necessary to use the intermittent connection mode to pull the clutch by hand to make the whole machine run briefly, and then idle for a while. Then check the operation of the whole machine, and when it is completely normal, prepare to start the driving work.
4. Start the vacuum pump system equipped with the sealing machine . When the vacuum storage tank reaches the specified vacuum, the machine can be started.
5. Before sealing the tank, the sealing machine should be operated for about 10mins, which makes the sealing machine more stable during work.
2. The main work content of the operator when the sealing machine is in normal operation
1. Before sealing the tank, check the tank lid and the material in the tank to avoid the wrong sealing. Put the correct tank lid into the tank rack.
2. The operator should ensure that the machine is working. It is not allowed to leave the machine at will and without any reason.
3. During the process of sealing the tank, it should be noted that the vacuum degree is within the specified range, and the abnormality should be adjusted in time.
4. The appropriate vacuum should be opened according to the weight of the solids in the canned can.
5. During the operation, the machine operator should visually inspect the appearance quality of the can sealing cup once every half hour, check whether the appearance of the can appears sharp or sharp, teeth, chipping; false seal, or vertical lip; Whether there is a rupture of the hem, whether the sliding seal is obvious, and whether the color coating on the outer wall of the can is scratched or scratched. If it is found to be defective, it should be shut down in time, and the maintenance personnel of the sealing machine on duty should repair the sealing machine.
6. During the sealing process, the full-time inspector of the canning workshop should check the quality of the “three rates†of the sealed cans every 2 hours. The inspector should report the inspection results to the machine operators in time. When the "three rate" quality of the sealing can not meet the specified requirements, the inspector should promptly request the operator to stop; at the same time, the maintenance personnel on duty the sealing machine repair the sealing machine.
7. During the process of sealing the tank, the operator of the machine should stick to the post and wipe and clean the surface of the sealing machine with a special cleaning cloth.
Third, the end of the canning, maintenance requirements for the machine before leaving work
1. After the canning production is completed, the power sealing switch of the sealing machine should be turned off, the vacuum system should be closed, and the sealing machine should be washed and cleaned.
2. Open the vacuum chamber of the can sealing machine and rinse the vacuum chamber.
4. Problems and treatments that often occur during canning and canning
1. The handling method of the card (biting) tank phenomenon: Shut down; use a screwdriver and a handle to loosen the screw. After opening the machine head, pry the can on the indenter, then install the roller and screw it tightly. After the machine head is put down; start, test a can, check the integrity of the sealing line, if there is no abnormality, it can operate normally.
2, canned appearance of the scratch treatment method: shutdown; remove the 1, 2 roller with the hand board, use the fine gauze to smooth the 1, 2 roller; after grinding, then install the machine, the screw is tightened; start, try Seal a can and check the integrity of the sealing line. If there is no abnormality, it can operate normally.
3, the sealing quality is not tight enough to handle: Shut down; use a screwdriver and a wrench to adjust the two rollers forward one space; start, seal a can, check the integrity of the sealing line, tightness, if there is no abnormality working normally.
4, the quality of canned cans, the body ditch is not enough to handle: Shutdown; if the body ditch is too small, the lower grinding spring will be lowered, such as the size of the body groove, that is, the small edge of the body groove appears with the iron pad to the lower die Position, put it to balance; start, test a can, check the integrity of the body groove, if there is no abnormality, it can operate normally.
5, canned sealing quality, not enough to cover the treatment method: shutdown; use the adjustable wrench to loosen the shaft and nut of the machine head, fine-tune up, and then tighten the screw; start, seal a can, check the integrity of the groove If there is no abnormality, it can operate normally; if the test cover groove is not enough, adjust a roller forward until the size of the cover groove meets the requirements.
