The car tires we usually see are made of rubber. Many of the products we usually see are made of rubber. There are many products that can be made by a single move, which is also very common in our lives. Some soles are also made of rubber. When processing rubber, a rubber extruder is required. A rubber extruder is a device for extruding. Now we come to understand the working principle and classification of rubber extruder.

1, plunger type
The extruder originated in the 18th century. The manual piston extruder for seamless lead pipes manufactured by Inger's Joseph Bramah in 1795 is considered to be the world's first extruder. Since then, in the first 50 years of the 19th century, extruders were basically used only in the production of lead pipes, macaroni and other food processing, brick making and ceramics industries.

2, screw type
的 The rubber extruder that appeared in 1870 was a hot-feed extruder. The rubber material fed by it must be hot-melted, and the...  أقل

Based on the direction of the material flow of the die and the angle between the center line of the screw, the die of the extruder can be divided into a right-angle die and an oblique die. . The screw extruder uses the pressure and shear force generated by the rotation of the screw to fully plasticize and uniformly mix the material, relying on the die for molding. Single screw extruder, twin screw extruder, screwless extruder and multi-screw extruder are the basic classifications of plastic extruders.

Uses

Extrusion of profile:

Adjusting the speed of the extruder and changing the structure of the extruder screw can be more suitable for the production of various plastic profiles such as PVC and polyolefins.

Modified granulation:

It is more suitable for the blending, modification and reinforcement of various plastics.

Pipe extrusion:

It is more suitable for PP-R pipes, PE gas pipes, PEX cross-linked pipes,...  أقل

There are many reasons for the heating of the automatic flat vulcanizing machine motor. Today, we will talk about the failure analysis of the automatic flat vulcanizing machine motor heating. I hope I can bring you some help.

1. Overload: Use a clamp meter to detect the normal current of the four-column hydraulic machine motor. If the current load of the motor is accidentally large or small, the hydraulic pressure may be increased; if it is just turned on The current is relatively large, and the current is too high when the current of the hydraulic system does not start to run, which indicates that the motor is faulty.

2. The bearing is stuck. Check whether the bearing of the motor of the hydraulic system of the vulcanizing press is stuck and the rotor is swept. The operator can also judge this fault by sound.

3. The voltage fluctuates greatly....  أقل
