Fig. 2 is the cross-sectional schematic of part-structure in Fig. 1;
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 depicted in figs. 1 and 2, compression type hot air welding unit 1 comprises fixing body 11 and the heat blower 12 of inner connection, and the front end of fixing body 11 is provided with weld part 114, and high temperature air can flow out from weld part 114.Fixing body 11 slides and is provided with pressure cover 111, pressure cover 111 is located at outside weld part 114, and and is provided with spring 113 between fixing body 11.
Adopt the compression type hot air welding unit 1 in the present embodiment, in actual plastic welding, sustainable generation high temperature air after heat blower 12 switches on power also exports, and high temperature air is incubated after transmission through fixing body 11, finally flows out from weld part 114.Adjustment weld part 114 makes it near workpiece, because weld part 114 is in by pressure, cover 111 is located at, and press cover 111 can slide along fixing body 11 under the effect of spring 113 to press down, workpiece pressing also cover sets out the space that can surround high temperature air, and in this space, high temperature air can keep collected state and continue workpiece position to be welded heating.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 the compression type hot air welding unit 11 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.
