Accompanying drawing explanation
The structural representation of the energy gathering type hot air welding unit that Fig. 1 provides for the utility model embodiment;
Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Be described in detail below in conjunction with the realization of concrete accompanying drawing to the present embodiment.
As shown in Figure 1, energy gathering type hot air welding unit 1, comprises heat blower 13 and fixing body 11.Fixing body 11 front end is provided with weld part 111 and pressure cover 112, pressure cover 112 is located at the outside of weld part 111, and the inside of fixing body 11 is also inserted with inside holding cover 114, and inside holding cover 114 is long tubular, its one end is communicated with weld part 111, and the other end is communicated with heat blower 13.Because fixing body 11 reality is interior outer double-layer structure, while water conservancy diversion high temperature air, there is good insulation effect.
After heat blower 13 switches on power, the sustainable hot-air that adds exports high temperature air, and high temperature air enters inside holding cover 114, finally flows out from weld part 111.
When actual welding, adjustment weld part 111 makes it near workpiece, because weld part 111 is in by pressure, cover 112 is located at, pressure cover 112 cover sets out the space that can surround high temperature air, and in this space, high temperature air can keep collected state and continue the heating of 111, workpiece portion to be welded.Workpiece is under the heating of high temperature air, and entirety is thermal softening in advance, local melting, now can be welded and fixed.
So, energy gathering type hot air welding unit 1 in the present embodiment, it is heat-conducting medium by high temperature air, in the transmission and welding process of high temperature air, there is preferably heat insulation effect, can concentrate and participate in welding with the state of higher temperature, compared with thermoplastic Welding of the prior art, adopting first overall pre-thermal softening to execute stressed method again, to have the thawing after welding effective, not easily leaves weld seam, the advantages such as the welding life-span is long.
Because the contact surface area of air heat exchange speed to air and medium is directly proportional, so in the process of air heat, need the contact area increasing air and adjacent media, and in the process of air conducting, need to reduce the contact area of itself and adjacent media, for meeting this principle, heat blower 13 internal diameter in the present embodiment is larger, and the internal diameter of inside holding cover 114 is less, so be provided with drogue 1141 in one end of inside holding cover 114, one end that drogue 1141 internal diameter is larger is connected with heat blower 13.Drogue 1141 is convenient to air and is entered less air from larger space, hinders impact little on itself flow velocity.
For the ease of connecting, energy gathering type hot air welding unit 1 in the present embodiment also comprises adapter sleeve 12, adapter sleeve 12 two ends are opening respectively, middle part is provided with baffle plate 121, heat blower 13 and fixing body 11 can insert from two openings respectively to be fixed with adapter sleeve 12, and inside holding cover 114 can pass baffle plate 121, its drogue 1141 is stuck in baffle plate 121 side, so the right-hand member of direction as shown inside holding cover 114 is fixed in adapter sleeve 12.
Inside holding cover 114 is away from the other end of drogue 1141, namely the left end in direction as shown, by the corresponding end of the second steady pin 113 with fixing body 11, namely the left end of direction as shown fixing body 11 interfixes, be connected and cover 12 block the baffle plate 121 of drogue 1141, make adapter sleeve 12, fixing body 11, inside holding overlap 114 threes and interfix.
As shown in Figure 1, one end of adapter sleeve 12 and heat blower 13 are fixed by the first steady pin 131, and the heat blower 13 after fixing docks with drogue 1141 and is communicated with.
As shown in Figure 1, weld part 111 in the present embodiment is die 111, die 111 has special shape, its sidewall is provided with steam vent, and when welding, die 111 directly can compress workpiece, impel it to be adjacent to and be out of shape, to strengthen syncretizing effect, the steam vent offered at its sidewall can make high temperature air flow out rear very first time contact workpiece, is its heating.The shape set-up mode of die 111 can have multiple, requires design, be set to cusp-shaped, can weld the workpiece such as ring-type, tubulose, circle, make it be out of shape and keep cirque structure in the present embodiment according to actual welding.
Pressure in the present embodiment is covered 112 and is slideablely fixed on fixing body 11 front end.Due in the process of welding, die 111 can force workpiece deformation to be adjacent to by continuous decrease, and presses cover 112 to need to be enclosed in weld part 111 outsides all the time, and opposite piece is static, so it needs to keep slidably state with die 111, the two is made to have the space of Relative sliding.
Due to the position of pressing cover 112 to arrange, overlapping with the position residing for aforesaid second steady pin 113, in order to prevent the two from interfering, pressure cover 112 offers positioning runner 1123, the second steady pin 113 passes this positioning runner 1123 and can slide in groove.Pressure cover 112 not only can not be interfered with the second steady pin 113 in the process of sliding, and the second steady pin 113 can also play the effect of location, prevents from deflecting in the process of pressing cover 112 to slide dislocation.Get final product direct control second steady pin 113 in the outside of pressure cover 112, make it load onto or take off, remove and install body 11 and overlap 114 with inside holding.
The structure of heat blower 13 can be multiple, can refer to various ripe air-heater structure, particularly, heat blower 13 in the present embodiment as shown in Figure 1, it has inner chamber, in inner chamber, be provided with quartz heating body 132, its one end is provided with the air inlet 133 that can enter inner chamber for normal temperature air, is fixed after the other end inserts adapter sleeve 12 by the first steady pin 131.
In use, normal temperature air continues input heat blower 13, when heat blower 13 is energized, quartz heating body 132 generates heat, and is high temperature air by the air heat flowing through its surface, final participation welding, when heat blower 13 deenergization, normal temperature air flows out without heating is directly last from die 111, cools workpiece, workpiece can complete the overall process of welding cooling on energy gathering type hot air welding unit 1, without the need to other cooling device and technique.
The present embodiment also provides plastic welding equipment, include one or more above-mentioned energy gathering type hot air welding unit 1 and other necessary equipment for plastic welding, an energy gathering type hot air welding unit 1 can be only set in plastic welding equipment, carry out independent welding process, also multiple energy gathering type hot air welding unit 1 can be set according to demand, weld simultaneously, it adopts high temperature air to be dielectric heating workpiece, welding, through pre-thermal softening, has welding syncretizing effect good, the advantages such as the welding life-span is long.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
