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 figures 1 and 3, push-in hot air welding unit 1 comprises weld part 11 and the heat blower 13 of inner connection.Wherein heat blower 13 inside is provided with calandria 132, and one end is provided with socket 135, and outside power supply is connected by socket 135 and calandria 132, and calandria 132 is connected rear heatable, provides high temperature air.

Weld part 11 comprises pressure cover 111, and be provided with air outlet (not shown) in pressure cover 111, the high temperature air exported from calandria 132 flows out from air outlet, is gathered in pressure cover 111.

Adopt the push-in hot air welding unit 1 in the present embodiment, in actual plastic welding, first its grafting is energized, calandria 132 starts to add hot-air, then make pressure cover 111 aim at or be located at the workpiece position to be welded needing welding, workpiece is under the heating of high temperature air, and entirety is thermal softening in advance, local melting, can be welded and fixed.

So the push-in hot air welding unit 1 in the present embodiment, compared with thermoplastic Welding of the prior art, adopts first overall pre-thermal softening to execute stressed method again, has the thawing after welding effective, not easily leave weld seam, the advantages such as the welding life-span is long.

Socket 135 can adopt various structure of the prior art, adopts five needle sockets in the present embodiment.

As depicted in figs. 1 and 2, push-in hot air welding unit 1 also comprises fixing body 12, and fixing body 12 inside is provided with cavity 122, and its one end is communicated with heat blower 13, and one end is communicated with weld part 11, can play guide functions.The first inlet suction port 121 is offered near one end of weld part 11 at fixing body 12.After welding terminates, stop high temperature air supply, access normal temperature air from the first inlet suction port 121, normal temperature air flows into weld part 11 from cavity 122, flows out from pressure cover 111 inside, to the workpiece cooling of having welded, make it cool fast, return to normal, without the need to re-using other cooling devices.

The concrete structure of heat blower 13 can have multiple, the structures such as such as hot hair dryer of the prior art all can realize, heat blower 13 in this enforcement as shown in Figure 3, it has inner chamber, calandria 132 is placed in its inner chamber, leave the gap 134 that can flow through for air between madial wall and calandria 132, air flow through this gap 134 time absorb heat, become high temperature air.Calandria 132 in the present embodiment adopts quartz heating structure, in actual applications, also can adopt other electrothermal structures.

As shown in Figure 3, be provided with the second inlet suction port 135 in heat blower 13 one end, normal temperature air can enter from this inlet suction port.The other end of heat blower 13, directly opens wide as opening 131 structure, and fixing body 12 can insert in this opening 131 nested with heat blower 13, and the inner space of the inside cavity 122 of fixing body 12 and heat blower 13.So the air in heat blower 13 enters from the second inlet suction port 135, flow through calandria 132 surface, finally flow out from opening 131, enter fixing body 12 inner, high temperature air is finally guided to weld part 11 by fixing body 12.

As shown in Figure 2, in order to strengthen fixing between fixing body 12 and heat blower 13, the two bearing is interfixed by steady pin 14, and this structure is prior art, does not describe in detail.

Fixing body 12 lateral wall in the present embodiment is provided with external screw thread 123.Due in actual use, need to adjust the distance between weld part 11 and workpiece, to reach the needs such as suitable temperature, so need to adopt the modes such as clamping first to fix push-in hot air welding unit 1, rotate after gripping and regulate fixing body 12, the position to clamp structure can be changed, namely have adjusted the distance between pressure cover 111 and workpiece.

Push-in hot air welding unit 1 in the present embodiment, multiplely can be arranged on different welding positions to process simultaneously, also can process workpiece heat separately, because it adopts socket 135 formula to be electrically connected with the external world, conducting and disconnection can be realized fast, and the mode adopting nested rear steady pin 14 fixing between fixing body 12 and heat blower 13, pull down fast after can taking out steady pin 14, so the push-in hot air welding unit 1 in the present embodiment is except having the advantages such as welding effect is good, its also have can Fast Installation dismounting feature, be convenient to installation and maintenance.

The present embodiment also provides plastic welding equipment (not shown), include one or more above-mentioned push-in hot air welding unit 1 and other necessary equipment for plastic welding, a push-in hot air welding unit 1 can be only set in plastic welding equipment, carry out independent welding process, also multiple push-in hot air welding unit 1 can be set according to demand, weld simultaneously, it adopts high temperature air to be dielectric heating workpiece, welding is through pre-thermal softening, there is 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.
