Working principle of sheet extruder

Working principle of sheet extruder

Plastic undergoes three processes on the exhaust screw; In the first stage, the plastic is compressed and heated to reach a basic plasticizing state; After the basically plasticized plastic enters the exhaust section, due to the sudden deepening of the screw groove in the exhaust section and the suction effect of the vacuum pump, the pressure drops sharply to a negative pressure state. The compressed gas and vaporized volatile matter inside the plastic melt foam in the melt, and the bubbles rupture under the stirring of the exhaust screw. The escaping gas is pumped away by a vacuum pump from the exhaust port; The melted material after exhaust treatment is compressed and homogenized again through the second compression section and second metering section, and the required product is extruded from the machine head.

Precautions for sheet machine

Precautions for sheet machine

matters needing attention (1) No debris is allowed inside the material, and foreign objects such as metal, sand, and gravel are strictly prohibited from entering the hopper. (2) The screw is only allowed to start at low speed, with an idle time of no more than 1 minute. After timely feeding, the screw speed can be gradually increased. The screw speed and current cannot exceed the parameters (3) When opening the cooling water, slowly open the valve to see if the temperature is within a controllable range, and do not suddenly open it completely. (4) When inspecting the appearance of the coating, operators must wear high-temperature gloves for operation to prevent high-temperature burns.

How to operate the sheet material machine

How to operate the sheet material machine

If it is the first time a sheet material machine is put into use, we should first heat the machine for about 40 or 50 minutes when turning it on. The recommended operating method is to manually pull the triangular belt of the motor until they are free; Pull 8 to 10 times continuously according to the normal working direction, then continue heating for about 10 minutes, and then start. However, due to the need for continuous heat supplementation in normal production, heating should continue; Adjust different temperatures according to the different properties of plastic.
