Extrusion molding, also known as extrusion molding in plastic processing, refers to a processing method in which materials are heated and plasticized by a screw while being pushed forward by the screw through the action between a cylinder and the screw of an extruder, and the materials continuously pass through a machine head to be made into products or semi-products with various sections. In the processing of polymer materials, extrusion molding refers to a molding method in which a polymer material melted by heat is forced to pass through a die head to form a continuous profile with a constant cross section under the pushing of pressure. The extrusion forming process mainly comprises the processes of feeding, melting and plasticizing, extrusion forming, shaping, cooling and the like.

After the plastic part is extruded from the die, the pressure is suddenly relieved to cause the phenomenon of die separation and expansion, and the shrinkage phenomenon occurs after the plastic part is cooled, so that the size and the shape of the plastic part are changed. In addition, since the plastic part is continuously extruded, the self weight is increased, and if the plastic part is not guided, the plastic part can be stopped, so that the plastic part cannot be smoothly extruded.

In order to adjust the width of the material, the worker sets the feeding speed at the head of the screw extruder and the drawing speed of the drawing device to a certain ratio.

After the feeding speed at the head of the screw extruder and the traction speed of the traction device are set to a certain ratio, the running state of the equipment during running fluctuates, so that the width of the plastic part also fluctuates, and further the size of the plastic part is not standard.

The implementation principle of the embodiment of the application is as follows: in the extrusion operation, the feeding device 1 firstly puts the material into the screw extruder 2, the screw extruder 2 then extrudes the material to form the plastic part 001, and the plastic part 001 sequentially passes through the first cooling device 3, the first traction device 4, the second traction device 5, the second cooling device 6 and the third traction device 7 and is finally wound by the winding device 8 to obtain a plastic part 001 product. And when the plastic part 001 passes through the width adjusting assembly 9 between the second cooling water tank 61 and the second traction device 5, the laser diameter measuring instrument 91 detects the width of the plastic part 001 passing through the laser diameter measuring instrument 91, when the width is too wide, the rotating speeds of the second driving motor 52 and the third driving motor 73 are increased, and when the width is too narrow, the rotating speeds of the second driving motor 52 and the third driving motor 73 are reduced.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
