Automatic filament feeding device provided with roller type deviation rectifying mechanism and used for EPP granulator

Abstract

The invention discloses an automatic filament feeding device provided with a roller type deviation rectifying mechanism and used for an EPP granulator. The automatic filament feeding device comprisesa machine table for mounting the EPP granulator. The automatic filament feeding device is characterized in that a conveying roller mechanism for conveying EPP long filaments to an inlet of the EPP granulator is arranged on the machine table, and the device further comprises the roller type deviation rectifying mechanism at the inlet of the EPP granulator, upper and lower deviation rectifying rollers mounted on an X-shaped cross bracket, a drive device for driving the X-shaped cross bracket to open and close, and a supporting frame for supporting the X-shaped cross bracket as well as a controller, wherein a photoelectric sensing device electrically connected to the controller is arranged on the supporting frame for emitting a signal to the controller for controlling the drive device to actwhile detecting that EPP long filaments pass through from a position between upper and lower deviation rectifying rollers, driving the X-shaped cross bracket to close for oppositely clamping the EPP long filaments through the upper and lower deviation rectifying rollers, and rectifying the long filaments to be aligned to the inlet of the EPP granulator. The device has a deviation rectifying function for the EPP long filaments, is better in filament feeding precision and stability, is simpler in structure and is lower in cost.

Description

technical field [0001] The invention relates to a post-processing equipment for EPP extrusion granulation, in particular to an automatic wire feeding device for an EPP granulator with a roller-type deviation correction mechanism. Background technique [0002] In the known technology, when EPP is granulated by extrusion method, the process is to put high-melt strength PP particles and compounding agent and other raw materials into the extruder to melt, and then extrude from the die hole to reduce pressure and foam into filaments, and finally pass through the workers. After being pulled out from the cooling pool, it is cut into small beads by a pelletizer and collected. The EPP granulator is mainly a roller granulator, the filament is fed through the inlet, cut off by two cutting rollers rotating in reverse, and finally discharged from the end outlet. Since the entrance of the pelletizer is narrow and long, the gap between the two cutting rollers is very small. In order to en...

Problems solved by technology

However, it is well known that the extruded and cooled EPP filament itself is difficult to maintain a shape for a long time, and it is easy to collapse under the action of gravity.

Especially in the process of the translation device driving the filament to slowly transport to the pelletizer inlet, the filament is easy to tilt down, causing the filament head to be deflected relative to the pelletizer inlet, and finally cannot be accurately fed into the pelletizer , still causing the blockage problem

Therefore, the current equipment often needs to be observed by workers when it is in use. Once it is found that the front end of the EPP filament is tilted, it will be corrected. This obviously increases the burden on the workers, takes time and effort, and increases the labor cost of the enterprise.
