Attention to the use of the extruder

1) check the outside and inside of the hopper before and after each extruder, check

whether the fastening bolts are loose, the safety cover is firm, the position of

each button switch is correct, and then the lubricating oil is added to the

lubricating parts, and the cleaning and health work of the equipment is done well.
2) notify staff around equipment when preparing to drive.
3) low speed starting

drive screw motor, check the main motor working ampere meter pointer swing is

normal, if the equipment operation has abnormal sound or screw operation is not

stable phenomenon, should stop immediately, find the relevant personnel maintenance

and solution.
4) the screw is not allowed to exceed 3min by air transport to the

test car. All the normal installation dies, the installation of the mould with the

connecting bolt, the use of a layer of molybdenum disulfide or silicone oil before

use, in order to facilitate disassembly.
5) at the initial stage of the feeding

production, the screw uses the minimum working speed, and the material should be

less and even. At any time, there is no abnormal change in the oscillating change

of the working current meter pointer of the motor.
6) after the extruder is put into

normal production, the operator should check the temperature changes of the bearing

parts frequently. When examining the temperature of motor and bearing parts, gently

contact the examination site with the back of the fingers. No rotating parts should

be touched by hand when the equipment is running.
7) when dismantling and installing

screws and moulds, it is not allowed to percussion parts directly with heavy

hammers. If necessary, hardwood should be knocked down for demolition or

installation.
8) when cleaning the screw, cylinder and mould residue, it must be

cleaned with bamboo or copper knives and brushes. No steel tools should be used to

scrape scraps or barbecue parts.
9) when the extruder fails, the extruder is not

allowed to run. When the extruder screw is rotated and the die is adjusted, the

operator is not allowed to face the outlet of the extruding cylinder so as to

prevent accidents.
10) when the extruder is working, the operator is not allowed to

leave the post. If he has to leave, the extruder should be stopped.
11) remove the

screw after parking. After the debris is cleaned, use a layer of antirust oil. If

temporarily unused, it should be wrapped and hung vertically in the dry and

ventilated place.
12) the extruders and moulds that are not used for a long time to

stop production should be coated with antirust oil to seal the entry and exit ports

so as to prevent foreign objects from entering.
