Abstract

The utility model discloses an electric heat sealing apparatus for plastic films. The heat seal of the prior polyethylene plastic adopts a special heat sealing machine. The utility model has the advantages of inconvenient operation, high thermal efficiency. The quality of the heat seal can not be ensured providing the electric soldering iron is adopted for the heat seal. The utility model provides a convenient hand-hold plastic film heat seal apparatus and is basis on the improvement of the electric iron. The chip plate is made into a long bar form, and thus the heat quantity is concentrated on the chip plate and then is transferred to pressing strips for conducting the heat seal of the plastic film. In addition, the pressing strips can be made into different widths as required with multiple purposes.

Description

Plastic welder with temperature regulation for plastic film

The utility model relates to a kind of plastic sheeting heat seal utensil.

Existing plastic sheeting heat seal, plastic bag sealing mainly adopts specialized equipment.Heat seal as polyvinyl chloride film is to adopt high-frequency plastic welder; Special-purpose heat-sealing machine is also used in heat seal for polyethylene foil.These device structure complexity cost an arm and a leg, and therefore simply carry out heat seal with the candle burning or with simple approach such as electric soldering irons for the pot foods packing, and these straightforward procedures can't guarantee heat sealing quality.

The packaging bag of aero-engine adopted igelite to make in the past, and high-frequency plastic welder is adopted in encapsulation.The back finds that chloride ion has corrosion attack to other part of driving engine, make packaging bag so regulation is used vinyon instead, so high-frequency thermocompressor just can't adopt.The aviation salvage shop have to be used the heat seal utensil of electric soldering iron as packaging bag instead.The package quality can't guarantee like this.

The utility model is exactly the heat seal for sealed polyethylene plastic, and particularly the package of aero-engine packaging bag provides a kind of hand-held instrument easily.

The utility model is to improve from electric flat iron, and all the respective element with electric flat iron is identical for handle (4), temperature control element (7).For heat is concentrated, it is up big and down small accurate trapezoidal that the section of shell (13) is made.Chip (1) is made elongate in shape, and its section becomes the rectangle of two stackings; Heater element---flatiron core (11) has two, is placed on the both sides of chip (1) respectively.The method of the material of flatiron core and resistor wire coiling is identical with electric flat iron.The both sides of flatiron core have two baffle plates (12) that the flatiron core is clamped also and chip is screwed together on shell (13).The bottom of chip (1) has dovetail furrow, and press strip (16) inserts in the dovetail furrow, and press strip can be made different in width as required, and can change.Between shell (13) and baffle plate (12), fill out, scatter and disappear from both sides in order to stop heat with asbestos.

The utility model temperature is adjustable, can transfer to suitable temperature with knob (3) according to the thickness of plastic sheeting, reaches best heat seal effect.Power is big, heating is fast, efficient is high.In addition, compare with special-purpose heat-sealing machine, structure is greatly simple, and price is considerably cheaper also, and operation is carried all more convenient.Press strip can be made different in width as required, and can change, and accomplishes one-object-many-purposes.The material of film can be polyethylene, polyvinylchloride, aluminium plastic membrane, paper film, glass fibre film.

Implement the utility model, can adopt the respective element of electric flat iron, as long as make shell, chip and press strip as required as handle, temperature control element, flatiron core etc.Be left can make by simple assembling exactly, small business particularly township and village enterprises all can make.
