The structural feeding cylinder body is fixedly installed with a fixed connecting ring on the outer surface of the external surface of the structural feeding cylinder. The inner surface of the fixed connecting ring is provided with a groove, and a pressing pad is movably installed on the inner side of the material cylinder. One side of the pressing pad is movably installed with a pressing column, and one side of the outer surface of the structural cylinder is fixedly installed near the lower end.
The current extrusion machine equipment involves an application structure, which includes a connecting block, a fixed connecting ring, and a connecting platform. The connecting block can be easily disassembled and replaced with a mold, and the fixed connecting ring can be well bonded to the extrusion machine. The adapter can place the blank well, thus bringing better sealing structure to the extrusion machine and bringing better prospects for use. The characteristics of the current application of the extrusion machine conveyor device are as follows:, The main driving roller and multiple auxiliary driving rollers are set on the frame, and the adjacent auxiliary driving rollers are mainly the transmission chain, driving roller, and auxiliary driving roller.
Because the main driving roller of the extrusion machine is connected to the driving motor through a chain, and there is a cooling platform on the outer side of the frame, and a straightening structure on the inner side of the frame, the current extrusion machine equipment can solve the shortcomings in existing technology, reduce the risk factors of workers' work, and complete preliminary alignment during transportation, facilitating subsequent operations. Nowadays, it is known that plastic extrusion machines, including inner tubes, have a core mold inside the inner tube, The outer tube is sleeved on the outer side of the inner tube, forming a cavity between the outer tube and the inner tube.
Common fault conditions: 1. When running the main motor, the main motor does not move or shuts down in an instant.
The main motor rotates, but the extruder screw does not rotate.
3. The extruder screw has a rotational speed ratio indicating that raw materials cannot be extruded.
4. There is waste in the extruded product.
5. The main motor switch power supply of the extruder fluctuates greatly.
6. Unstable extrusion of raw materials.
Cause: 1. The main motor switch power supply is not connected, the heating and warming time is not enough, or a certain electric heater is not working, resulting in excessive torque and causing the motor to load.
2. Loose belt, deviation, and common faults in the gearbox.
3. The reasons why raw materials cannot be produced by extrusion molding include: (1) there is no raw material in the silo, (2) the feeding port is blocked by dirt, (3) causing a "railway bridge" where dirt enters the extruder, (4) metal materials and other hard objects (such as nuts) falling into the extruder screw block the screw groove, and raw materials cannot be transported, (5) the extruder screw is twisted off, (6) the extruder screw temperature is too high (internal cooling is not good), (7) The temperature of the material barrel is too high, and (8) the viscosity of the material is high, causing the extruder screw to not move. (9) Short circuit, unstable frequency converter with fluctuations, (10) The extruder screw is damaged, and the extruder screw deviates.
4. There is waste in the raw materials, and there is too much carbon deposition on the screws.
5. When a certain section of the electric heater is not working, the torque is unstable, the main motor rolling bearings are not well lubricated or damaged, and the vibration is large.
6. The raw material feeding port is a "railway bridge", the main motor speed ratio is uneven, there are fluctuations, the heating and cooling system is not well matched, or the thermal resistance deviation is large
