Description
Technical field
The present invention relates to the welding method in a kind of moulding process of electronic tag cigarette packing case, specifically the packing plastics plate of sheet is welded into the welding procedure of packing case.
Background technology
Existing cigarette packing case comprises paper packaging box and soft copy packing case, although paper packaging box is still in a large amount of use, but it is high, big for environment pollution and the reason such as cannot to reuse to there is cost in it, in the continuous research of various countries scientific and technical personnel, just there is novel soft copy packing case, this casing adopts modified polymer material, has the advantages such as light, waterproof, intensity are high, reusable.Then because the material of this casing is macromolecular material, when casing is shaping, the clad plate of sheet is needed to form the entirety being not easy to destroy by means such as gluing or welding, in order to meet this intensity, general all employing welds this technological means, if application number is the patent of invention of 201210543752.3, namely have employed high frequency welding machine to weld, the marginal portion of welding within 1 ~ 2 second, is made all to melt rear welding by heating, weld surfaces externally and internally simultaneously and solder side melt simultaneously, surfaces externally and internally destroys serious, especially surfaces externally and internally out-of-flatness is smooth, jagged generation, in follow-up automatic makeup cigarette working procedure, damage cigarette phenomenon to produce, puncture the external packing of bar cigarette, be difficult to meet finished product bar cigarette factory calibration.
Summary of the invention
Technical problem to be solved by this invention is for above-mentioned the deficiencies in the prior art, and provides a kind of and do not destroy welding position and the welding technique of the electronic tag cigarette packing case that surfaces externally and internally is smooth, solder side tensile and compressive strength is high.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A welding technique for electronic tag cigarette packing case, is characterized in that, step is as follows:
The first step, by slice plastic plate according to fold line, the free end of one of them welding edge contacts or leaves with the coincidence line of another welding edge the spacing being not more than 20mm, and two welding edges are placed with an angle, the size of described angle is 35 ~ 70 °;
The luminous energy thermal source that an inside is filled with inert gas is placed in second step, the angle that formed between described two welding edges, this luminous energy thermal source is arranged on the separated time of angle, and be 10 ~ 50mm with the vertical range of welding edge, described luminous energy thermal source sends continuous radiation luminous energy and utilizes air heat mode to act on solder side, the emission wavelength of luminous energy thermal source is 360 ~ 2400nm, luminous efficiency is 18 ~ 30LM/W, the surface temperature of luminous energy thermal source is 300 ~ 1200 DEG C, the operating temperature of luminous energy thermal source is 110 ~ 2900 DEG C, and the heat time is 7 ~ 15S;
3rd step, by heating after the pressing of two thermofussion welding edge fits, applied pressure is 10 ~ 50 kilograms.
The described free end of a welding edge contacts with the coincidence line of another welding edge, and the angle formed between two welding edges is 45 ~ 55 °, and the vertical range of luminous energy thermal source and welding edge is 25 ~ 35mm.
Compared with prior art, two limits of welding are fixed with certain angle by the present invention in advance, and two solders side of a placement luminous energy thermal source to the welding edge of two in angle directly heat in angle.The existence of angle, not only can heat two welding edges simultaneously, can also play the effect of heat build-up, linear thermal source is made to form the heating surface of a dispersion, by the design of angle and cooperatively interacting of heating distance, achieve whole heat fused of whole solder side, after welding, intensity is high.When the present invention welds, only welding two solders side, the back side of two other face and weld is not then directly heated, in heating process, ensure that the molten state of solder side and the surface at the back side of solder side is relatively intact, so after last pressing, the weld inner surface of packing case is intact smooth.
