Abstract
The invention discloses a plastic film welding device. The device comprises a heating plate driven by a driver, a heating electrode matched with the heating plate and two working platforms for loading plastic films, wherein the heating electrode is arranged between two working platforms, the heating plate is arranged above the heating electrode. The device can be used for welding common plastic films and particularly for welding ethylene-tetrafluoroethylene copolymer films, increase the strength of welding seams of the welded ethylene-tetrafluoroethylene copolymer films to bigger than that of the ethylene-tetrafluoroethylene copolymer films and increase the connection firmness and safety.
Description
Technical field
The present invention relates to a kind of plastic foil connection device, relate in particular to a kind of plastic film welding device, mainly be applicable to the welding of ethylene-tetrafluoroethylene copolymer film.
Background technology
In the prior art, the welding manner of plastic sheeting has multiple.China Patent No. " 90216859.2 " discloses a kind of plastic sheeting soldering apparatus, includes the adjusting knob of adjustable economize on electricity hot body position and two rollers are housed under housing.This soldering apparatus is mainly used in the welding processing of large tracts of land plastic sheetings such as greenhouse, booth.
Also there is the laser beam of employing to connect plastic material, in this mode, adopt the upper layer of material of laser beam irradiation over against laser beam, two materials are heated at the contact-making surface place of asking at the subsurface material of permeable upper layer of material of laser beam and laser beam impermeable, two materials are connected to each other together under pressure then.The permeable material of laser beam can be the black in the visible wavelength range with optical term.In addition, be well known that generate a linear laser light beam, material and laser beam are done relative motion in welding operation for this reason, to generate required welding shape.A prerequisite according to the welding process of this irradiation technique is the thermal responses of plastics under the IR irradiation.The plastics that scribble the IR absorbing material under irradiation behind the heat energy in the absorbing IR source heat energy accumulate gradually.Thereby the temperature that reaches in the accumulation plastics of heat energy is decided by the meter types of energy, as energy density and irradiation time.In addition, material behavior such as thermal conductivity are also very important. and one step of key of welding process is from solid-state phase transformation to liquid state.In order to reach this fusion temperature, because the thermal conductivity of plastics is low thereby need certain heat time heating time.In principle, can shorten irradiation time by improving energy dose.But this way makes the range of work reduce, and causes welding quality to descend.
Since above-mentioned two kinds of plastic foil welding manners all be at common plastics, in the prior art, also do not have the special welding device of ethylene-tetrafluoroethylene copolymer film.Ethylene-tetrafluoroethylene copolymer (ETFE) is mainly used in Corrosion resistant linings.This material has the corrosion resistance characteristic of polytetrafluoroethylene (PTFE), the distinctive strong adhesiveness of pair metal is arranged again simultaneously, overcome the not cohesive defective of polytetrafluoroethylene (PTFE) to metal, its average coefficient of linear expansion is near the linear expansion coefficient of carbon steel in addition, make ETFE (F-40) become desirable composite with metal, have extremely good anti-negative pressure characteristic.Have above-mentioned characteristic just because of the ethylene-tetrafluoroethylene copolymer film, can not adopt the common plastics soldering apparatus directly to weld.
Summary of the invention
The objective of the invention is to overcome the problems referred to above that the Plastic Welding device exists in the prior art, a kind of welder that mainly is applicable to the ethylene-tetrafluoroethylene copolymer film is provided, the present invention not only can be used for the welding of common plastics film, be particularly useful for the welding of ethylene-tetrafluoroethylene copolymer film, and make ethylene-tetrafluoroethylene copolymer film after the welding in the intensity of seam crossing greater than its body intensity, be connected firmly, strengthened security.
For achieving the above object, the technical solution used in the present invention is as follows:
A kind of plastic film welding device, it is characterized in that: comprise by heating plate, the heating electrode that cooperates with heating plate of driver drives and be used to place two workbenches of plastic foil, described heating electrode is arranged between two workbenches, and heating plate is arranged on the heating electrode top.
Be provided with insulating barrier between described workbench and the heating electrode, workbench, insulating barrier and heating electrode are fixedlyed connected in aggregates.
Described workbench is a vacuum absorbing platform, has the adsorption hole that is used for the adsorption plastic film on the working face of workbench.
Described driver is hydraulic unit driver, motor driver, air cylinder driven device.
Employing the invention has the advantages that:
One, the present invention is primarily aimed at the characteristic of ethylene-tetrafluoroethylene copolymer film and designs, and applicable to the welding of common plastics film.
Two, the present invention is cooperated with heating electrode by the driver drives heating plate, heating plate heats the upper strata plastic foil, heating electrode is to lower floor's plastic foil heating, and heating plate applies a pressure to heating electrode, and heating plate cooperates with heating electrode and adds thermal weld, make the welding balance even, be welded as continuous welding, need not manually-operated, the efficient height.
Three, workbench of the present invention is a vacuum absorbing platform, have the adsorption hole that is used for the adsorption plastic film on the working face of workbench, the plastic foil that is placed on after the welded edge stack on the workbench is fixed, guaranteed the uniformity of plastic foil edge weld.
Four, be provided with insulating barrier between workbench of the present invention and the heating electrode, make to be welded between heating plate and the heating electrode and finish, reduced infringement to workbench, improve weld strength, and energy energy efficient, workbench, insulating barrier and heating electrode are fixedlyed connected in aggregates, have improved the stability of welding and the uniformity of weld seam.
Five, driver of the present invention is hydraulic unit driver, motor driver, air cylinder driven device etc., and type of drive is various, can select according to actual conditions, has increased flexibility.
Six, the present invention welds the ethylene-tetrafluoroethylene copolymer film, can make ethylene-tetrafluoroethylene copolymer film after the welding in the intensity of seam crossing greater than its body intensity, be connected firmly, strengthened security, reduced the generation of security incident.
