How to deal with things about rubber extruder?

Rubber extruder is a high-efficiency, continuous, low-cost, and wide-adapted processing and molding method. For some special processing and molding, the rubber extruder reaction extrusion process requires strict control of temperature, pressure, material residence time, and its distribution and other process parameters. If you also want to understand these, you can continue to look down.

How to install the head of rubber extruder?

（1） The machine head should be assembled and installed on the rubber extruder as a whole.

（2） Before assembling the machine head, wipe off the grease applied during storage, carefully check the cavity surface for scratches, scratches, and rust, perform the necessary polishing and then apply a layer of silicone oil to the runner surface.

（3） Assemble the machine head plates in order, apply high-temperature grease to the threads of the bolts, and screw in the bolts and flanges.

（4）Place the perforated plate between the machine heads so that the perforated plate is pressed firmly without overflowing.

（5）Before tightening the fastening bolts connecting the head and the rubber extruder, the horizontal position of the die should be adjusted. The square head can be adjusted horizontally, and the round head is based on the bottom surface of the molding die and adjusted with the bottom surface of the head die. flat.

（6） Tighten the connecting bolts, tighten the machine head fastening bolts, install the heating ring and thermocouple, pay attention to the heating ring to be close to the outer surface of the rubber extruder.

（7） Install the sizing sleeve and adjust it in place, and check whether the center lines of the main engine, sizing sleeve, and tractor are aligned.

（8） Turn on the heating power to heat the rubber extruder's nose and machine evenly. At the same time, open the cooling water at the bottom of the hopper and gearbox and the water inlet valve of the exhaust vacuum pump. When heating, first adjust the temperature of each part to 140 degrees, and if it rises to 140 degrees, hold it for 30 to 40 minutes and then raise it to the normal production temperature.

What are the reasons and treatments for the failure of the main motor to start?

1. Reasons:

(1) The driving program of rubber extruder is wrong.

(2) The interlocking device related to rubber extruder works

2. Treatment method:

(1) Check the program and restart rubber extruder according to the correct driving sequence.

(2) Check the main motor circuit.

(3) The oil pump does not turn on, and the rubber extruder cannot be turned on.

What are the characteristics of molding?

1. The rubber material is further mixed and plasticized by the rotation of the rubber extruder screw to ensure that the quality of the extruded semi-finished rubber material is more dense and uniform;

2. Rubber extruder has a wide range of applications. By exchanging dies, rubber profiles of various cross-sectional shapes and preformed semi-finished products for press dies can be extruded.

3. The extruded products are fast, and the rubber extruder has high production efficiency, which is conducive to automated production.
