How to maintain the plastic extruder machine? – Suzhou Polytime Machinery Co., Ltd.

The plastic extruder is not only important machinery for the production and molding of plastic products but also an important guarantee for the recycling of plastic products. Therefore, the waste plastic extruder should be used correctly and reasonably, give full play to the efficiency of the machine, maintain a good working state and prolong the service life of the machine. The use of plastic granulators includes a series of links such as machine installation, adjustment, commissioning, operation, maintenance, and repair, of which maintenance is an indispensable and important link.

What is the production process of plastic extruder?
The basic process of sheet production by plastic extruders is as follows. First, add raw materials (including new materials, recycled materials, and additives) into the hopper, and then drive the motor to drive the screw to rotate through the reducer. The raw materials move in the barrel under the push of the screw and change from particles to melt under the action of the heater. It is evenly extruded by the die head of the extruder through the screen changer, connector, and flow pump. After salivation is cooled to the pressing roller, it is calendered by the fixed roller and setting roller. Under the action of the winding system, the finished sheet is obtained after the excess parts on both sides are removed by trimming.

What are the functions of the plastic extruder?
1. The machine provides plasticized and uniform molten material for plastic resin extrusion molding plastic products.

2. The use of the pellet extruder machine can ensure that the production raw materials are evenly mixed and fully plasticized within the temperature range required by the process.

3. The pellet extruder provides molten material with a uniform flow and stable pressure for the forming die so that the plastic extrusion production can be carried out stably and smoothly.



How to maintain the plastic extruder machine?
1. The cooling water used in the extruder system is usually soft water, with hardness less than DH, no carbonate, hardness less than 2dh, and pH value controlled at 7.5 ~ 8.0.

2. Pay attention to safe start-up when starting up. At the same time, pay attention to starting the feeding device first. Stop the feeding device first when stopping. It is strictly prohibited to transfer materials by air.

3. After shutdown, clean the barrel, screw, and feeding port of main and auxiliary machines in time, and check whether there are agglomerates. It is strictly prohibited to start at low temperatures and reverse with materials.

4. Daily attention shall be paid to the lubrication of each lubrication point and two tandem thrust bearings, and whether there is leakage at the screw seal joint. If any problem is found, it shall be shut down and repaired in time.

5. The plastic extruder shall always pay attention to the abrasion of the brush in the motor and maintain and replace it in time.
