Description
Technical field
The utility model relates to heat-sealing devices, more particularly to a kind of welding heat generating device.
Background technique
When using film packaging, it will usually seal to bilayer film, be made by the heating wire fever of high temperature
Film hot melt is obtained, is then bonded together.When mattress packaging, needs to seal film, then pack tightly mattress
In film.The heat-sealing device of existing mattress packing film is usually a heating wire, then will be generated heat by a bracket
The both ends of silk tense, and when heat-sealing, bracket declines together together with heating wire, and by film compression on bottom plate, heating wire adds
Heat simultaneously heats film, then seals film tight.Since the usual One-sided Widths of mattress are both greater than 1m, particularly with big mattress
Unilateral length can be more than 2m, require that the length of heating wire and bottom plate will be more than 2m when heat-sealing to this kind of big mattress；Bottom
Plate uses the structure of aluminium alloy, is plane with film contacts face, and heating wire is elongated as a straight line, theoretically heating wire
Contact with bottom plate is parallel.But in practice, the bottom plate of aluminium alloy is due to processing technology or the effect expanded with heat and contract with cold
And deform, contact surface has slight concave/convex-shaped structure and is formed, and will make contact surface out-of-flatness.Such structure is in heating wire
Film can not be adjacent on bottom plate when heat-sealing, have the case where part is crossed weldering and do not welded partially, just will affect film
Sealing effect.Device uses initial stage, and this phenomenon is unobvious, but after being used for a long time, will become obvious, and at this time usually
Just need replacing bottom plate.It, all can be with the presence of concave-convex uneven situation no matter bottom plate to be changed to the plate of which kind of high-flatness.
Utility model content
Based on this, the purpose of the utility model is to provide a kind of welding heat generating device, has and adjust heating wire simultaneously certainly
The advantages of adapting to bottom plate.
