Description

Automatic wire feeding device of EPP granulator with roller type deviation rectifying mechanism

Technical Field

The invention relates to post-processing equipment for EPP extrusion granulation, in particular to an automatic wire feeding device of an EPP granulator with a roller type deviation rectifying mechanism.

Background

In the prior art, when EPP is granulated by an extrusion method, the process is that raw materials such as high melt strength PP particles, a forming agent and the like are put into an extruder to be melted, then the raw materials are extruded from a die hole to be decompressed and foamed into filaments, and finally the filaments are pulled out from a cooling pool by workers and then cut into small beads by a granulator to be collected. EPP pelleter is mainly the roller pelleter, and the filament is sent into through the entry, is cut off by two reverse rotation's cutting roller, discharges by terminal discharge gate at last. Because the inlet of the granulator is long and narrow, the gap between the two cutting rollers is very small, and in order to ensure the smoothness and stability of the shredding process, certain requirements are provided for the tiling and dispersion uniformity of the filaments and the filament feeding speed.

Traditional pay-off mode is artifical pay-off, and during actual operation, the workman erects on bearing roller with EPP filament (100 duo gen) bundle after, then pushes the income of pelleter in, but the shortcoming is very obvious: the filaments are not enough to be separated due to accumulation, the dispersibility is poor, the feeding speed is not easy to control, the uniform speed is difficult to realize, the filaments are extremely easy to clamp, the blockage of a granulator is caused, the working stability and the reliability of the filaments are greatly reduced, the working efficiency is lower, and the labor intensity of workers is higher.

For this purpose, we have designed a kind of automatic silk feeding device, such as the devices disclosed in patent nos. ZL2018208162347 and 2018208161895. The core mechanism of the automatic wire feeding device adopts a translation device (an electric screw pair or a linear module) to drive a wire feeding support to horizontally move towards the inlet of the granulator, and an automatic clamping mechanism for clamping and fixing the EPP filament is arranged on the wire feeding support. After the device is actually used, the spreading and dispersion of EPP filaments can be enhanced, the filament feeding stability is improved to a great extent, and the filament jamming condition is effectively prevented. However, in long-term use, we have found that such automatic thread feeding devices still expose several problems:

1) The translation device mainly adopts an electric lead screw pair or a linear module to drive wire feeding, and although the precision and the stability are good, the speed is low and the efficiency is low. And under the condition of long-term use, the maintenance cost is higher once the translation device is damaged.

2) After the automatic clamping mechanism clamps the EPP filament, the front end of the EPP filament needs to extend out of one section so as to extend into the inlet of the granulator. The length of the extended EPP filament cannot be too short in order to avoid interference of the translation device and its wire feed carriage with the front of the cutter. However, it is well known that the extruded and cooled EPP filaments themselves are difficult to hold in shape for long periods of time and are prone to collapse under the influence of gravity. Especially, in the process that the translation device drives the filaments to slowly convey towards the inlet of the granulator, the filaments are easy to decline, so that the head of the filaments deflects relative to the inlet of the granulator, and finally the filaments cannot be accurately conveyed into the granulator, and the problem of blockage is still caused. Therefore, the existing equipment is often observed by workers at the side when in use, and the EPP filament front end is straightened once the EPP filament front end is found to be inclined, which obviously increases the burden of the workers, wastes time and labor and also increases the labor cost of enterprises.

Therefore, the automatic wire feeding device of the EPP granulator has the advantages of deviation rectifying function for the EPP filaments, better wire feeding precision and stability, simple structure, easiness in maintenance and low cost.
