Processing device and processing method of polyethylene glass fiber reinforced plastic composite molding spiral corrugated pipe

Abstract

The invention relates to a device and method for processing a spiral corrugated tube, and in particular relates to a device and method for processing a polyethylene glass fiber reinforced plastic composite molded spiral corrugated tube. The device comprises a drawing and squeezing mold, a roll bending device, a winding machine, a heating adhesive-spraying device and a polyethylene plastic extrusion mold which are arranged in sequence, wherein the drawing and squeezing mold is used for processing glass fibers into glass fiber reinforced plastic strips; the roll bending device is used for bending the glass fiber reinforced plastic strips into glass fiber reinforced plastic spiral rings; the winding machine is used for propelling the glass fiber reinforced plastic spiral rings; the heating adhesive-spraying device is used for spraying an adhesive to the glass fiber reinforced plastic spiral rings; and the polyethylene plastic extrusion mold is used for extruding polyethylene towards inner and outer walls, to which the adhesive is attached, of the glass fiber reinforced plastic spiral rings to ensure that the polyethylene glass fiber reinforced plastic composite molded spiral corrugated tube is formed. By adopting the device and the method, the advantages of corrosion resistance, easiness in processing and molding and recyclability of polyethylene are integrated with the characteristics of high corrosion resistance, high strength, high elastic modulus and easiness in molding of glass fiber reinforced plastics, so that the composite molded tube has the advantages of easiness in processing, corrosion resistance, high strength, low cost, small possibility of deformation, recyclability and the like.

Description

technical field

[0001] The invention relates to a processing device for a spiral corrugated pipe and a processing method thereof, in particular to a processing device and a processing method for a spiral corrugated pipe formed by composite molding of polyethylene glass reinforced plastics. Background technique

[0002] In recent years, with the development of composite materials, plastics and steels have been widely used in the fields of municipal drainage, chemical anticorrosion, and sewage discharge due to their unique advantages of high rigidity and low cost. However, during the use of the steel belt reinforced polyethylene spiral corrugated pipe, once the steel belt is exposed to the plastic, it will corrode quickly in a humid and sewage environment, and the ring stiffness will become smaller and smaller, which will eventually cause a collapse accident. Contents of the invention

[0003] Aiming at the technical problems existing in the prior art, the invention provides...

Examples

Embodiment Construction

[0034] see Figure 5 , polyethylene glass fiber reinforced plastic composite molding spiral bellows, two layers of polyethylene layer 24 coated on the inside and outside of the glass fiber reinforced plastic layer 21, the structure is consistent with the traditional steel belt reinforced polyethylene spiral bellows, the difference is that the steel belt is replaced by glass fiber reinforced plastics.

[0035] As a preferred embodiment of the present invention, the attached Figure 1~4 Shown is a processing device for compositely forming a spiral corrugated pipe made of polyethylene fiberglass, and the specific structure is as follows:

[0036] The alkali-free glass fiber is the glass fiber pultrusion yarn 2 placed on the glass fiber pultrusion creel 1, which is drawn out through the glass fiber wire ring frame 22, the glass fiber wire mesh plate 3 and the glass fiber row rod 23 in sequence, and the glass fiber knitted mat Leading out from the knitted felt support 4, the non-a...
