CN101380819A, title " production device of wall tube of large aperture framework-tube polyethylene winding structure "; Production device of wall tube of large aperture framework-tube polyethylene winding structure comprises combustion system, skeleton pipe induction system, extruding machine, skeleton pipe reel, mobile trolley used, electrical control cabinet, cooling back installation, pressure frame, rotation roller frame; Particularly flat die oral area length dimension is 170-230MM in the flow passage system; The overmold angle is 181-200; An end of support link is connected with driving sleeve through bearing pin in the roller mould, and its other end is connected with the support link frame, and the support link frame connects to form with final drive shaft through the axle of having strong market potential.Its weak point: this equipment adopts screw mandrel to promote final drive shaft moving linearly, drives fixed thereon 13 overlap support link framves, support link, driving sleeve, to the steel cylinder central motion, not only power consumption is big around power transmission shaft for steel cylinder; Rigidity to final drive shaft requires very high; Manufacturing cost is high, and since stressed excessive, be prone to cause the final drive shaft distortion; Cause the synchronism of 13 support link framves, support link, driving sleeve, steel cylinder to guarantee, directly influence stripping result.
The utility model content
Purpose of design: avoid the weak point in the background technology, design a kind of making that can either satisfy the large aperture framework plastic tube, the Wrapping formed equipment of a kind of large aperture framework plastic tube that again can be conveniently stripped.
Design: in order to realize above-mentioned purpose of design.1, rotating shaft be between in the design of screw-rod structure, be one of technical characterictic of the utility model.The purpose of doing like this is: drive in the shape of a spiral with 15 swivel nuts and cooperate owing to be positioned at 15 sections screw rods that spacing in the rotating shaft distributes; When rotated, 15 sections screw rods in the rotating shaft drive synchronously 15 swivel nuts and rotate, 15 swivel nuts again respectively the template II that drives separately of the pull bar through separately move downward; After the template II moves downward certain distance; Crank gets into separated region around track shaft and the little mould rotational trajectory intersecting area of passing by, and then drives the template III by crank and moves downward; The mould external diameter is diminished, the product demoulding smoothly; Secondly, 15 sections screw rods that spacing distributes in the rotating shaft are just just as 15 sections reinforcements, and it can effectively advance to guarantee that the intensity of rotating shaft is indeformable.2, the wound plastic tube forming panel by template I, template II, template III constitute one just round, and the design of template I calibration 165 degree, template II calibration 40 degree, template III calibration 155 degree, be the utility model technical characterictic two.The purpose of doing like this is: because different calibration; Determined the size that this die opening mechanism drives bearing pressure, and the application's design can make the driving bearing pressure be in optimum state; Can satisfy the rigidity requirement of rotating shaft rotation, have low cost of manufacture, indeformable characteristic again.
Technical scheme: the Wrapping formed equipment of a kind of large aperture framework plastic tube; It comprises production device of wall tube of large aperture framework-tube polyethylene winding structure; Template I in the said production device of wall tube of large aperture framework-tube polyethylene winding structure, template II, template III constitute one just round, template I calibration 40 degree, template II calibration 155 degree, template III calibration 165 degree, pull bar one end adopt with swivel nut that axle is connected, the other end passes through crank one end and is connected with the template II; The crank other end is connected with the template III through first rotating shaft; Second rotating shaft cooperates with the swivel nut screw drives, and second rotating shaft rotation, 30 circles, swivel nut move 180mm, and the mould internal diameter shrinks 13mm.
The utility model is compared with background technology, and one is that 15 screw threads drive simultaneously, and the screw rod load is disperseed, and screw rod is carried more than 5 times than like product; Two is that 15 strong points drive simultaneously, increases multi-point support for 7 meters moulds of length, makes mould circularity high, is out of shape little; The 3rd, the device fabrication required precision is low, overcomes single screw drive major axis, and strong point gap is little.Difficulty of processing is big.
