Abstract
A biaxially oriented polyvinyl chloride pipe production apparatus comprises an extruder, a pipe orifice mold, a sizing sleeve, a cooling water tank, a first drawing machine, a heating tank, a thermotank, a biaxial orientation die, a cooler and a second drawing machine which are sequentially and linearly positioned to form a production line, the biaxial orientation die is a cylindrical body, the head of which is conical, the center of the biaxial orientation die is provided with a round hole, a positioning wire rope is arranged between the pipe orifice mold and the biaxial orientation die, one end of the positioning wire rope is fixed on the pipe orifice mold, the other end of the positioning wire rope passes through an undrawn pipe blank, and is then inserted into the central round hole of the biaxial orientation die and firmly locked on the biaxial orientation die by a bolt, and the drawn pipe is transferred to a cutting and packaging mechanism by the second drawing machine. The biaxially oriented polyvinyl chloride pipe production apparatus has the advantages that: the structure of the apparatus is simple, the apparatus is easy to put into practice, the cost is reduced, the apparatus can have different models of biaxial orientation dies, products with a different draw ratio can be produced as long as the biaxial orientation die is replaced, and the apparatus can bring remarkable economic and social benefits.
Description
Technical field
The utility model relates to the technology of preparing of high-performance polychloroethylene pipes, particularly a kind of polyvinyl chloride pipe stretched in two directions production equipment.
Background technology
Polychloroethylene pipes occupies an important position in numerous plastic pipes, resistance was little when it had light weight, acid-alkali-corrosive-resisting, conveying fluid, insulating properties is good, construction rapidly easily, advantages such as convenient, the raw material source abundance of long service life, secondary operations, low price, be widely used in fields such as worker, agricultural production and daily life, but with respect to the toughness and the shock resistance of PE tubing excellence, the deficiency of its mechanical performance is still needed solution badly.In recent years, reported polyvinyl chloride pipe stretched in two directions (being called PVC-O tubing) abroad in succession, this tubing by specific biaxial orientation technology, can obviously strengthen the mechanical strength and the impact strength of tubing in process.
Biaxial tension polyvinyl chloride (PVC-O) tubing all is to adopt " off-line " processing technology (two step processing methods) usually, extrusion molding and the thick material embryo of tubing (PVC-U) that cooled off is expand into by heating and pressurization require size to realize being orientated.Experimental study and practical application proof biaxial tension polyvinyl chloride have outstanding performance, and still " off-line " processing technology speed of production is low, and the equipment investment height is difficult to promote.
We grope by scrap build and test of many times, developed a kind of polyvinyl chloride pipe stretched in two directions production equipment, it stretches by the stretching die head by force to the experimental temperature relief through baking oven heating and water bath with thermostatic control homogenizing with the tubing normally extruded, obtains biaxial tension tubing after the cooling.
The utility model content
The purpose of this utility model is at above-mentioned existing problems, a kind of polyvinyl chloride pipe stretched in two directions production equipment is provided, this production equipment is simple in structure, easy to implement, can obviously improve the pvc pipe material performance, save material, reduce cost, have tangible economic benefit and social benefit.
The technical solution of the utility model:
A kind of polyvinyl chloride pipe stretched in two directions production equipment, comprise extruder, tubing mouth mould, calibration sleeve, cooling water tank, first hauling machine, heating cabinet, insulating box, the biaxial tension die head, the cooler and second hauling machine and successively straight line location constitute production line, the biaxial tension die head is the column type body that head is cone, its center is provided with circular hole, between tubing mouth mould and biaxial tension die head, be provided with the location cable wire, one end and the tubing mouth mould of location cable wire are fixed, the other end passes in the base pipe that do not stretch, insert the center hole of biaxial tension die head then and by bolt the biaxial tension die head is locked, the back tubing that stretches is delivered to cutting and packing by second hauling machine.
The reducing ratio of described biaxial tension die head is 1: 1.2～1.8.
Advantage of the present utility model is: this device structure is simple, easy to implement, reduce cost, and the stretching die head has different model, only needs to change the product that die head can production different stretch ratio, has tangible economic benefit and social benefit.
