Multi-layer wire-splitting knife device

Abstract

The invention discloses a multi-layer wire-splitting knife device. The device includes a horizontally extending rotating shaft and a base used for mounting the rotating shaft. The number of rotating shafts is at least two and is arranged from top to bottom. Each rotating shaft is provided with a knife rest which rotates together with it. A plurality of blades are uniformly distributed on the kniferest about the axis of rotation; for two adjacent rotating shafts, the number of tool rests on the lower rotating shaft is twice the number of the knife rest on the upper rotating shaft. A pluralityof reversing wheels for guiding the plastic film after being split to the next tool rest are arranged on the base. The base is provided with a driving mechanism capable of rotating the knife rest on two adjacent rotating shafts in opposite directions. According to the multi-layer wire-splitting knife device provided by the invention, the old blade can be replaced with a new blade without stopping.The continuity of production can be ensured and the production efficiency is improved. The plastic film can be split into filaments according to needs and the application range is wide.

Description

technical field [0001] The invention relates to the field of wire splitters for plastic wire drawing, in particular to a multi-layer wire splitter device. Background technique [0002] The plastic woven industry is an industry that combines plastic processing and textile industry. With the wide application of plastic woven products in various industries in our country, the status of my country's plastic woven industry has gradually improved. The production process of the plastic wire drawing unit is: after the plastic raw materials and auxiliary materials are mixed, they are heated and melted by the extruder, and the extruder melts and extrudes it into a film. Stretching, orientation, and shaping produce flat yarns, and finally wind these flat yarns on bobbins to make spindles. Among them, the flat wire splitting device is an important part of the plastic wire drawing unit, which is composed of a splitting tool holder, a blade and other components. [0003] At present, onl...

Problems solved by technology

[0003] At present, only one set of blades can be installed on the wire dividing tool holder used by the plastic wire drawing unit. The blades are often worn out during the continuous production of flat wires. Hot drawing, shaping, winding into ingots and other processes for flat yarn

At present, the replacement of the blade needs to be shut down, resulting in discontinuous production, increased material loss, increased energy consumption, and reduced flat yarn production efficiency.

In addition, when a plastic film needs to be divided into multiple plastic filaments after being divided into multiple filaments, the plastic film needs to pass through multiple blades in sequence. However, the current blade arrangement makes the equipment occupy a large area, which is not conducive to equipment storage.
