A device for correcting ellipse deformation of modified polypropylene pipe

Abstract

The invention discloses a device for correcting ellipse deformation of a modified polypropylene pipe, which comprises a main body part, an ellipse correction part and a driving part. Both are vertically provided with support plates, and the top between the two support plates is equipped with a rotating drum through bearings; the ellipse correction components include telescopic part 1, screw rod, strip plate, telescopic part 2, rotating roller, gear 1, Boss-shaped sleeves, ring teeth and rectangular hinged frames, telescopic parts 1 are vertically arranged on both sides and bottom inside the drum. According to the ellipticity of the modified polypropylene pipe, the invention can rotate the screw to rise to different heights, so as to locate the modified polypropylene pipe with different ellipticity, and at the same time, adjust the four telescopic The length of piece two is used to position modified polypropylene tubes of different sizes.

Description

technical field [0001] The invention relates to the field of technical ellipse deformation correction devices, in particular to an ellipse deformation correction device for modified polypropylene pipes. Background technique [0002] Polypropylene is a general-purpose plastic resin with wide sources and low price. It has a very wide range of uses. Polypropylene is a polymer formed by the addition polymerization of propylene. It is a white waxy material with a transparent and light appearance and a density of 0.89~ 0.91g / cm3, flammable, melting point 165°C, softens at around 155°C, use temperature range -30~140°C. It can resist the corrosion of acid, alkali, salt solution and various organic solvents below 80 ° C, and can decompose under high temperature and oxidation. Polypropylene is widely used in the production of clothing, blankets and other fiber products, medical equipment, automobiles, bicycles, parts, pipelines, chemical containers, etc., and is also used in food and...

Problems solved by technology

[0003] At present, most of the production methods of modified polypropylene pipes are extrusion molding, and in the process of extrusion production and preparation of modified polypropylene pipes, the modified polypropylene pipes that have just been extruded are in a high temperature state, and the shape is easily deformed. In order to ensure the goodness of the modified polypropylene pipe, it is necessary to correct the deformed plastic pipe. The current rounding method is to arrange two rotating rollers laterally and symmetrically around the plastic pipe, and adjust the distance between the rotating rollers to be the same as that of the plastic pipe. After the diameters of the plastic pipes are consistent, the rounding of the plastic pipes is completed, so that the diameters of the plastic pipes are consistent in all directions. However, the structure of this rounding device is too simple, and the distance between the rotating rollers is not easy to adjust, and the plastic pipe cannot be changed. The thickness of the tube, and the rounding is not correct, the fixation is not firm enough, and the rounding effect is poor
