Door/window frame plastic steel profile extrusion production line

Abstract

The invention discloses a door / window frame plastic steel profile extrusion production line. The door / window frame plastic steel profile extrusion production line comprises a plastic extruding machine, a hopper connected with a feeding inlet of the plastic extruding machine, a water cooling device connected with the machine head of the plastic extruding machine, a splitting device arranged on thedownstream portion of the water cooling device, and a discharging device arranged on the downstream portion of the splitting device; the hopper comprises a spiral mixer, and the spiral mixer comprisesa middle shaft which is arranged at the center part of a hopper shell and is in rotary fit with the hopper shell, and further comprises an upper spiral material uniformizing assembly, a middle spiralmaterial uniformizing assembly and a lower spiral material uniformizing assembly which are sequentially arranged on the middle shaft from top to bottom; and the splitting device comprises a supporting table, a synchronous translation mechanism and a cutting-off mechanism, and a cutting edge of a cutter is in an M shape. Through the door / window frame plastic steel profile extrusion production line, the problems that an existing production line needs additional equipment, and raw materials are mixed and dried through manpower are solved, and in addition, the problem that an existing splitting device can cause cutting is solved.

Description

technical field [0001] The invention relates to the technical field of production of plastic-steel door frame profiles, in particular to an extrusion production line for producing plastic-steel door frame profiles. Background technique [0002] Door and window frame plastic steel profile extrusion production line includes extruder, water cooling device, labeling device, cutting device, discharge device, etc. The raw material enters the extruder from the hopper, and after being plasticized in the extruder, it is extruded from the die of the machine head. After being cooled by the water cooling device, the extruded plastic steel profile enters the labeling device, and is pasted with a label tape by the labeling device. The door and window frame plastic-steel profiles enter the cutting device, which cuts the door and window frame plastic-steel profiles into required lengths, and then the cut door and window frame plastic-steel profiles are fed into the discharge device by the c...

AI Technical Summary

Problems solved by technology

[0007] In view of this, the object of the present invention is to provide a door and window frame plastic steel profile extrusion production line to solve the problem that the door and window frame plastic steel profile extrusion production line in the prior art needs to invest equipment and manpower to mix and dry the raw materials entering the extruder. Dry, the work of the slitting device on the existing production line will produce a large number of chips, poor cross-section smoothness and other technical problems
