Start-up steps and precautions:
(1) Check whether the oil level of the gear oil in the distribution box reaches the middle position of the oil window.
(2) Turn on the heating and observe whether the temperature of each zone is normal. Pass the cooling water and change the cooling control to automatic control. The cooling water valve in each zone can be opened half a turn or a turn.
(3) Start the main engine (at the same time pay attention to whether there is any abnormal noise from the screw), open the cooling valve of the distribution box, at this time, a person needs to add water to the barrel at the discharge port position, and start the feeder after about 10 seconds after starting the main engine. , and keep adding water. After waiting for about 20 seconds, start the rotary cutting motor and keep adding water. After the mold hole is discharged, the water can be stopped. Note that the speed of the main motor can be set to 25HZ, the feeding speed to 12HZ, and the rotary cutting speed to 20HZ when starting up. Observe the current of the main motor. The rated current of the main motor is 139A. If the current of the main motor is too large, Approaching 139A, it is necessary to rapidly reduce the speed of the feeder, or increase the speed of the main motor.
(4) The temperature of the copper pipe and the water outlet pipe under the barrel is very high, please do not touch it, and the water outlet pipe will be under pressure due to the generation of water vapor, so be sure to lock the pipe joint.
(5) When the rotary cutting motor is running, it is strictly forbidden to open the rotary cutting cover, and it is strictly forbidden to pick up the product by hand.
(6) It is strictly forbidden for hands or any other objects to approach the feeding port of the barrel.
(7) When the feeder is running, it is strictly forbidden for any foreign matter other than the material to enter.
(8) The control cabinet must be grounded.
(9) It is strictly forbidden to touch the barrel cover during the production process.
Shutdown steps and precautions:
(1) Turn off the heating first.
(2) Turn off the feeder
(3) Wait about 20 seconds to turn off the host
(4) Wait about 5 seconds to turn off the rotary cutting motor
(5) Exit the rotary cutting motor and open the rotary cutting cover
(6) Loosen the lock nut, withdraw the knife hoist, and remove the knife shaft
(7) Remove the mold seat. Loosen the nuts symmetrically, no one can stand in front of the mold, and people stand in front of the side of the mold to remove the screws. Loosen each nut two times first, and loosen the nut in cycles until the mold seat can be pushed inward by hand, which proves that there is no pressure, and all the screws can be loosened. It is quicker to disassemble the die holder.
(8) After the mold base is removed, start the main engine immediately. When no material comes out from the discharge end, add water to the discharge port until the front discharge port comes out with clean water, then stop adding water. After the discharge port is not out of water, stop running the main engine. , At this time, the screw can be pulled out for cleaning, and the barrel also needs to be cleaned. The screw cannot be exchanged. After the screws are cleaned, align them and install them in the barrel (after aligning the screws, you can lean against the two screws, turn them to the screws together, and test whether the two screws are aligned). After installing the screws, be sure to run the screws vulgarly to ensure that There is no problem with the installed screws (when running the screws, you can use a round tube to support the ends of the two screws, so that you can test whether the screws are installed correctly, but you must pay attention to safety).
(9) Use a feeding rod and a hammer to smash the mold out, put the mold and the manifold into the fire, burn the material inside into carbon ash, and then take it out for further cleaning.
(10) After shutdown, the cooling water can be turned off.
Product: (1) After the material is discharged normally, the shape of the product is not good. For example, with a small tail, the first thing to consider is that the cutting knife is not adjusted properly. You can tighten the rotary cutting motor forward a little, but not a lot. , if it still doesn't work, you need to stop and readjust the cutter. Before production, after the rotary cutter is installed, the rotary cutter needs to be fixed, and the fixed screw rod is on the jacket of the rotary cutter motor base mounting slide rail, with a black handle.
(2) If the product is too thick, the speed of the rotary cutting motor can be accelerated, otherwise the speed of the rotary cutting motor can be slowed down.
(3) If the product is too dry or the puffing degree is too large, you can increase the moisture or adjust the raw material formula.
