Nine, common faults and inspection and maintenance of blowing equipment
30. Failure: There is a pinching injury on the lower edge of the outer side of the bottle mouth (it is determined to be pinched by the finger when the bottle is turned over or the bottle chain of the welding ring machine is collided)
Check: 1. Check the height of the handover between the bottle holding and turning finger and the bottle taking finger, and adjust the bottle holding and turning finger from the bottle taking finger to the appropriate bottle clamping position. 2. Check the height of the welding ring machine when the bottle holding finger and the bottle feeding finger are handed over. Is the location appropriate.
31. Failure: After the bottle is blown out, the small tail is flattened and cannot be used (the key is to check the accuracy of the position of the embryo feeding finger after the embryo enters the mold)
Check: 1. First, determine whether there are a large number of numbers or fixed numbers; 2. If a large number of small tails are flattened and the numbers are not fixed, check the blowing parameters and whether the lamp box heating lamp is damaged. 3. If the same number is fixed, check the handover of the fingers of each electric cylinder from front to back, mainly whether the embryo is skewed on the embryo feeding finger when it moves laterally into the mold after taking the embryo from the intermediate station. It means that the spring corresponding to the feeding finger is loose, and a tighter spring can be replaced. Make sure that the preform will not skew when moving into the mold, so that the bottom mold orientation rod is concentric with the small tail.
4. It is also necessary to adjust the height of the preform feeding fingers to ensure the verticality of the preform after entering the mold. 5. At the same time, observe whether there are pinch marks between the upper and lower edges of the blown bottle mouth. (1) First, there is a pinch mark for a single fixed number. , unscrew the right finger limit bolt and move left. That is, the finger is moved to the left as a whole; if there is a clip mark on the right side, the side feeding finger is moved to the right as a whole. (2) There are clip marks on multiple numbers. Method 27, item 4, adjust the embryo feeding stroke.
