Description

Dual-purpose hot-melt welding machine

But the utility model relates to the facility that the melting welding plastics connect, but especially for the dual-purpose hot-melt welding machine that the melting welding plastics connect, is applicable to butt joint, the socket weld of φ 63-φ 110 polyethylene (polypropylene, polybutene) tubing (pipe fitting).

But the melting welding plastic tube is a kind of novel pipeline material.It is to be formed through extrusion molding by polyethylene or polypropylene or polybutene etc., this pipeline, but have deformation plasticity preferably and good heat sealability.Therefore, their connection and metal tube, PAP, crosslinked polyethylene pipe is different.But it is, many at present with butt joint, socket joint, electric smelting welding for the melting welding plastic tube.The electric smelting welding needs special injection moulding electric melting pipe fittings, though this pipe fitting joint connects conveniently, costs an arm and a leg and processing difficulties, so economy is bad.And but the heat sealability that utilizes tubing welds to connect to tubing and need not joint (only needing joint when threeway, the reducing), and easy and simple to handle, good economy performance.In view of what put down in writing in the market welding machine and the Chinese patent communique: as plastic straighttube hot melt docking machine (CN2277878Y), plastics special piece hot melt docking machine (CN2277879Y), all there is function singleness in plastic tube butt joint socket joint welding machine (CN2202632Y), volume is big, equipment is heavy, shortcoming such as many, the welding quality instability of artificial governing factor when welding.

The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, makes out a kind of dual-purpose hot-melt welding machine that can finish butt joint, socket weld that can save investment.

The purpose of this utility model is such realization: comprise that the supporting mechanism (frame) by main frame is linked to be an integral body with parts such as transmission mechanism, clamping device, moment handwheel and stops, it is characterized in that the twin shaft guide rail is housed on the supporting mechanism (frame) and the clamping device that synchronous cog belt drives has been installed, the synchronous cog belt two ends are equipped with synchronizing jugged belt wheel, the synchronizing jugged belt wheel of one is connected by its pivot pin with the moment handwheel, be connected with stop and bearing on the supporting mechanism, the heater and the planing tool of detachable replacing is installed on the bearing.

The ratchet that matches is housed in the sleeve of described moment handwheel and cooperates with screw mandrel, screw mandrel cooperates with spring.

Slide rule on the described stop is screwed the end at clamping device, and the other end is fixed on the sliding sleeve, in end tube and the nut spring is housed, and the location cooperates with hole on the slide rule by pin.

The complete various socket joint die sleeves of heating plate and model are arranged on the described heater, and temperature control element and thermometer are housed.

Two folding spikes are housed under the described supporting mechanism.

The utility model is owing to adopt said structure, make its have stable drive, differential little, need not safeguard, guiding accuracy height, processing be easy, it is simple and easy to install, it is reliable, easy to adjust to limit moment, stability and reliability that clamping is firm, spacing accurately, can guarantee welding quality, simple in structure, a tractor serves several purposes good economy performance is fit to advantages such as open-air indoor construction.

Describe in detail below in conjunction with accompanying drawing.
