Description

A corrugated pipe extrusion speed feedback adjustment system

technical field

The utility model relates to an adjustment system, in particular to a corrugated pipe extrusion speed feedback adjustment system.

Background technique

The corrugated pipe extruder usually relies on the pressure and shear force generated by the rotation of the screw, so that the material can be fully plasticized and uniformly mixed, and formed through the die, and finally produces the production equipment of the corrugated pipe. It is used as a production equipment for plasticizing, conveying materials and The extruder that provides the molding pressure determines the plasticizing effect of the material, the degree of mixing, the uniformity of temperature and the stability of extrusion pressure, etc. The plasticizing effect has a great influence on the internal quality and appearance gloss of the product; mixing The degree will affect the performance uniformity of each point of the product; the uneven temperature of the extruded product will easily cause uneven size and deformation of the product, and even cause local overheating and decomposition, which will reduce the performance of the product; the fluctuation of extrusion pressure and extrusion speed will cause the product Dimensional fluctuations, unstable production, and even the phenomenon that the product is stuck or broken. The screw speed is one of the extremely important process parameters in the extrusion molding process. Increase the speed, increase the output, increase the shear rate, and the material The decrease in viscosity is beneficial to the plasticization of the material, but the increase in the speed also needs to consider the plasticizing capacity of the extruder and the melt pressure range, otherwise the material flow rate is too fast, which may cause the material to be pressed into the machine head before it is fully plasticized , Seriously affect the product quality; reduce the speed, reduce the output, and the moving speed of the forming module must be adjusted accordingly to meet the needs of production.

In the production of corrugated pipes, each corrugated pipe needs to be weighed to determine the overall quality of the corrugated pipe. In the past, the weighing of the corrugated pipe was carried by two workers to the electronic scale for weighing, which was not only time-consuming and laborious, but also due to the Slow, adjust the corrugated pipe extrusion speed when there is a problem, the adjustment has lagged behind, which brings great waste to production.
