Abstract
The invention provides a method for smelting inner layer plastic and outer layer plastic of a spring extension tube, in particular to a method for improving the connecting intensity of an inner layerand an outer layer of the spring extension tube by leading a plastic coated peel of an inner layer spring steel wire to be melted with an outer layer plastic film with a heating device. The method adopts the following scheme: one heating and smelting work procedure is added in the existing equipment, namely, a non-contact heating device or contact heating device leads the partial temperature of the plastic coated peel to increase and achieve melting point before intertwining the plastic film or after intertwining the plastic film, so that the plastic coated peel is smelted with the plastic film to obtain needed connection strength. A heating device adopts various heating and smelting methods such as thermal radiation, induction heating, laser, plasma, or ultrasonic wave, etc. The method solves the problem that the service life of the spring extension tube obtained by the existing equipment is short because the spring is easily separated from the plastic film after repeated tension, andprovides a smelting method for the inner layer plastic and the outer layer plastic, therefore, the extension tube has the advantages of high connection strength for smelting the inner layer plastic and the outer layer plastic, long service life, etc.
Description
Affiliated technical field
The present invention relates to a kind of processing method of spring extension tube, especially a kind of method that improves spring extension tube internal and external layer plastics join strength.
Background technique
Spring extension tube is a kind of of flexible pipe, and its tube wall is embedded with steel wire, soft good bandability, and have stretchability, and of many uses, be mainly used in family expenses and industrial vacuum vacuum cleaner, (central authorities) vacuum dust collector, ventilation duct, outdoor cleaning industrial dedusting system etc.The structure of spring extension tube as shown in fig. 1, it comprises inside and outside two-layer, internal layer is the spring of being made by plastic steel wire 1a, skin is the plastic film 1c that parcel covers the spring outside, it is entwined by one deck pvc or PUR material.
The course of working of existing winding process equipment is as follows: by spring coiling machine plastic steel wire 1a is rolled into spring-like, it constantly rotates and is pushed into the extrusion outlet of a plastic extruder in the process of rolling, because the width of extrusion outlet equals or is slightly larger than the pitch of spring, the plastic strip of extruding just constantly is wound into and forms plastic film 1c on the spring, again by just forming spring extension tube 1 after the water cooler cooling.For making plastic film 1c flexible with spring, plastic reinforcing bar 1a smears last layer glue (special-purpose compatibilizer) in advance before rolling into spring, make between its plastic skin 1b and the plastic film 1c and bond by glue, cohesive force insufficient strength between internal layer that obtains like this (spring) and the skin (plastic film 1c), in use, through after flexible, the bending repeatedly, the cementation of glue will be lost efficacy, coming unstuck is that spring and plastic film 1c break away from, and the working life of the feasible spring extension tube that processes by this method is short.
Summary of the invention
The objective of the invention is to solve the not enough problem of internal and external layer adhesion strength of the spring extension tube that above-mentioned existing process equipment obtains, it utilizes heating equipment to make the plastic skin and the welding of outer layer plastic film of inner layer spring steel silk, has advantages such as the spring extension tube of making internal and external layer join strength height, long service life.
The present invention adopts following scheme to realize: because easier realization fusion between the plastics of same high temperature (softening point is to fusing point) under pressure, and come out to form the outer layer plastic film from the extrusion outlet of plastic extruder is high temperature (near fusing point), the outer plastic skin of the inner layer spring steel silk that is wound is low temperature (normal temperature), therefore in the existing equipment processing technology, increase by one welding operation, promptly use non-contact heating or contact heating device that spring place local temperature is raise, just can make plastic skin and plastic film reach welding behind the fusing point, obtain the join strength that needs.

Above-mentioned induction heating is Frequency Induction Heating, high-frequency induction heating or superaudio induction heating, utilize magnetic induction eddy current heating principle, make the Spring Steel Wire heating by induction coil, plastic skin and plastic film are carried out realizing after the indirect heating welding of plastic skin and plastic film.
Above-mentioned laser is for to fix laser beam, and shine the spring position of the spring extension tube that rotation is advanced behind the winding plastic film, make plastic skin absorb laser energy and carry out the interior local heating of tiny area, the contact surface fusing of two kinds of plastics forms the welding zone, and plastic skin and plastic film are fused to together.
The spring position of the spring extension tube that above-mentioned plasma advances facing to rotation behind the winding plastic film for torch neck that will be fixing, the heat of the high-temperature plasma electric arc that produces acts on and forms local heating on the outer layer plastic film and make its fusing, and heat conducted to plastic skin, plastic skin and outer layer plastic film are fused into one.
Above-mentioned thermal radiation, induction heating, laser, isoionic method all belong to the non-contact heating.
Above-mentioned ultrasound is to use a ultrasonic wave to meet sb. at the airport to produce the high-frequency ultrasonic vibrations, and the high density energy that acts on the vibration of ultrasonic wave on the plastic film after the winding working procedure produces and after localized hyperthermia melts plastic skin and plastic film is fused to together.Ultrasound belongs to contact heating.
For avoiding the too high plastics excess molten that makes of temperature, plastic skin or plastic film after using infrared thermometer to heating carry out thermometric, and reach and stop heating when temperature is set by Temperature Feedback control is set,
In addition, plastic skin or plastic film outward appearance after using camera to heating show by display device, operator are more clearly visible and understand product, takes place to reduce substandard products.
The invention has the beneficial effects as follows: before or after using plastic extruder winding plastic film, by non-contact heating means such as thermal radiation, ultrasound, induction heating, laser, plasma heating, make reinforcing bar outer plastic skin or plastic film temperature rising local melting, finally make plastic skin and plastic film fuse into one, process the spring extension tube that obtains like this and can reach the higher join strength of internal and external layer, make at long-term constantly telescopic process medi-spring and plastic film can not break away from, prolonged its working life greatly.
