Description
Technical field
The present invention relates to heat-sealing devices, more particularly to a kind of welding heat generating device.
Background technology
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 is packed, needs to seal film, then pack tightly mattress
In film.The heat-sealing device of existing mattress packing film is typically a heating wire, then will be generated heat by a holder
The both ends of silk tense, and when heat-sealing, holder 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 partly do not welded, film will be influenced
Sealing effect.Device uses initial stage, this phenomenon unobvious, but after being used for a long time, will become apparent, 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 plank of which kind of high-flatness.
Invention content
Based on this, the object of the present invention is to provide a kind of welding heat generating device, there is adjustment heating wire and adaptive
The advantages of bottom plate.
A kind of welding heat generating device, including fixing piece, holder, adaptive part, pushing support element, heating wire, two stretchings
Part, multiple springs, actuator and controller；The fixing piece is fixed on the bracket, and the adaptive part is relatively described
Fixing piece is arranged in parallel, and the pushing support element is connect with the adaptive part by multiple springs, the actuator one
End is fixed on the pushing support element, and the other end of the actuator is fixed on the bracket and the pushing is driven to support
Part moves back and forth, and two tensioning members are separately fixed at the both ends for pushing support element；Two tensioning members will be described
Heating wire is tensioned, and heating wire is tightly attached to the adaptive part towards on the side of the fixing piece；The two of the heating wire
End is separately connected the positive and negative anodes of power supply；The controller controls movement and the power on/off of the heating wire of the actuator.
Welding heat generating device of the present invention is capable of the deformation of adaptive fixing piece, by adaptive part and fixing piece compared with
It sticks together well, even if fixing piece generates a little deformation, the welding quality in heat seal process will not be influenced, ensure that preferably
Heat sealability.
Further, including two actuators, the movable end of two actuators are separately fixed at the pushing
The both sides of support element.Two actuators can balance thrust, and the movement for pushing support element is more stable.
Further, the actuator is cylinder.
Further, the fixing piece, the adaptive part and the pushing support element are the hollow pipe of aluminium alloy,
Or the fixing piece, the adaptive part and the pushing support element are aluminum alloy solid pipe.The hollow pipe energy of aluminium alloy
The weight of device entirety enough being reduced, and at low cost so that the smaller model of load-carrying ability may be used in the selection of cylinder, and
Plant energy consumption reduces, and activity is more convenient.
Further, the tensioning member includes that a connecting seat, a bakelite and a tension block, the connecting seat are fixed on
On the pushing support element, described bakelite one end is vertical with the connecting seat to be fixedly connected, the other end and the tension block
It is fixedly connected, the tension block tenses the heating wire.Bakelite has good insulation effect, effectively by it is conductive from
It adapts to part and pushing support element is spaced apart.The heating wire can be tensed well by tensing block.
Further, face opposite with the adaptive part on the fixing piece is plane.The flatness of this plane is got over
Height is better for the heat-sealing effect of film.
Further, further include multiple limited posts, which is socketed in the spring, and the one of the limited post
End is fixed on the pushing support element, and a gap is formed between the other end and the adaptive part.Limited post is conducive to bullet
The limit of spring.
Further, the heating wire is wrapped with insulating layer.Insulating layer, which is arranged, can prevent the heating wire of high temperature from contacting
Film is clung when to film, plays the role of isolation, action principle is identical as the principle of non-stick pan.
Further, including two heating wires, two heating wires are tensioned by the tensioning member of both sides.Two
A heating wire provides more hot-sealing lines together, and sealing effect is more preferably.
Further, it is covered with high-temp glue layer of cloth on the adaptive part.High temperature carcass plays heat-insulated and protection
Effect, protects adaptive part.
In order to better understand and implement, the invention will now be described in detail with reference to the accompanying drawings.
