Description

Technical Field

[0001] The utility model relates to a new type of two - machine co - extrusion machine for PVC profiles, belonging to the field of plastic extrusion. Background Art

[0002] PVC is one of the most widely used plastic materials and is a non - crystalline material. The PVC production line mainly consists of an extruder, a die, a sizing table, a cutting machine, and a stacking table. Among them, according to different products, the extruder and the die are divided into two types: with co - extrusion and without co - extrusion. In the co - extrusion technology, the layout form of the extruder is very important. In actual production, co - extrusion machines have been widely used, but most co - extrusion machines have large limitations in use after installation, with an insufficiently compact structure and a large occupied space. After retrieval, it is found that the Chinese patent with the publication number CN217862724U discloses a co - extrusion tooling. In this patent, raw materials are added to the feeding funnels of three extruders, and then the extruders are started. After heating and plasticizing, the raw materials are extruded from the discharge ends of the extruders. The base profile is automatically formed under the action of the extruder and enters the interior of the co - extrusion tooling through the extrusion action. Subsequently, the material extruded by the first extruder forms the basic part of the base profile, the material extruded by the second extruder forms the first protective layer and adheres to the surface of the base profile, and the material extruded by the third extruder forms the second protective layer and adheres to the surface of the base profile. Through the cooperation of the conveying groove and the forming groove, it is ensured that the protective layer material is accurately coated at the predetermined position of the base profile. Finally, the sealing gasket in the sealing groove is pressed against the surface of the base profile, and the formed and coated profile is output from the output end of the co - extrusion tooling. However, the three extruders in this patent are installed on the same plane and fixedly set. If the extrusion position needs to be changed, all three extruders need to be adjusted and cannot match extruders of multiple specifications, and the occupied space for placement is large.
