Description

A wire drawing machine

Technical field

The invention belongs to the field of plastic woven bag production, and specifically relates to a wire drawing machine.

Background technique

Plastic woven bag is one of the very common packaging bags in our daily life. It is widely used in all aspects of daily necessities. According to the composition of the main materials, it can be polypropylene bags, polyethylene bags, etc.; it can be divided according to the sewing method. For sew bottom bags, hem bottom bags. The main production process is to use plastic raw materials to extrude the film, cut, and uniaxially stretch into flat yarn (ie drawing), and then weave through warp and weft to obtain the product, which is generally called a woven bag or a snakeskin bag.

The plastic flat yarn obtained by drawing in the production process is referred to as flat yarn for short in the plastic braiding industry, also known as cutting fiber. It is the basic material for the production of plastic woven fabrics. The flat yarn is melted and extruded from a specific variety of polypropylene or polyethylene resin. After forming into a film, it is divided into strips longitudinally. The strips are heated at the same time for drafting and orientation and then shaped, and finally wound into flat yarn spindles for weaving knitted fabrics. The production of flat yarns is the first process in the production of plastic knitted fabrics. The most important process. The device for producing flat yarn is the drawing machine. The process of producing flat yarn by the drawing machine is divided into tube film and flat film according to the film forming method. According to the cooling method after film formation, it is divided into air cooling, water cooling and indirect cooling. It is divided into hot plate, hot roller, and hot air, and is divided into concentrated cycloid winding, single-spindle torque motor winding and magnetic torque winding according to the winding forming of the spindle.

The process of producing flat yarn through a wire drawing machine is roughly as follows: raw material modification, blending, coloring, filling, preparation, extrusion and silk making and winding, etc., that is, the raw materials are modified, mixed and colored, and then filled and combined. It is formulated and extruded into a film in the extrusion film forming module. The film is cooled and passed through the traction roller assembly. The hot drawing orientation is performed at the heat traction assembly, and then the heat setting is performed at the heat setting assembly through another traction roller assembly. , And finally through another traction roller assembly and then wind the winding assembly. This is a systematic production process, involving many technological processes and parameters, including anti-aging, anti-degradation, adjustment and control of temperature, pressure, and flow during the extrusion process, rheological behavior of the extrusion process, power consumption, and yield Technical issues such as traction ratio, blow-up ratio, draft ratio, crystallization cooling, orientation, heat treatment setting, forming in the winding process and quality inspection of spindles in the drafting process are all required in the flat yarn production process. Finely regulated. Because the conditions that need to be controlled are more complicated, it is easy to produce uneven material distribution and plasticization in the process of producing flat yarns through the wire drawing machine, resulting in flat yarns with flatness defects, that is, there are gaps or unevenness in the shape, and In the production process, when the drawing machine has some special conditions such as deviation and chaos, the operators need to deal with the flat wire on the drawing machine in real time, and perform corresponding operations according to the problem of the flat wire, but the drawing machine is working In the process, each traction roller pulls a number of flat yarns for forward transportation. The number of flat yarns is dense and the width is small. Therefore, if the operator is accidentally involved in the corresponding operation process, it will cause great danger and endanger the operation. The life safety of personnel, for this reason, on the basis of the existing technology, it needs to be optimized so that it can effectively protect the life of the operator without hindering the operator from performing the corresponding operation. This is the current production of flat wire. Operator Cheng needs the protection, but it has not been solved now.
