Description

Hot Air Spray Nozzle for Synthetic Resin Welding Machine

This proposal is to inject hot air for welding the resin material to be welded, and in particular, the surface of the joint of the resin material to be welded (hereinafter referred to as the object to be joined) is heated and melted in an optimal state for welding. The present invention relates to a hot air spray nozzle for a synthetic resin welding machine, which allows welding to be carried out more reliably and to perform a quick welding operation.

In general, the work site has used a synthetic resin welding machine as a means for assembling and installing various synthetic resin structures by connecting and welding each other to be joined as a synthetic resin.

Such a synthetic resin welding machine has been developed in various structures and shapes according to the purpose or use of the synthetic resin welding machine, one of which is the synthetic resin welding machine (1), as shown in Figure 1a, the operation handle for energizing the power supplied from the outside ( 21) and an operating manipulator (2) having a controller (22) to be maintained at an appropriate temperature, and the hot air spray nozzle (31) mounted at the top of high temperature hot air generated in connection with the operating manipulator (2). The hot air supply unit (3) for heating the junction of the object to be joined (a) and the synthetic water support material disposed to be connected to the operation operation unit (2) on one side of the hot air supply unit (3) is dissolved at the top stage It was configured as a molten resin supply part 4 which extrudes the molten resin b through the molten resin supply nozzle 41, so that the objects to be joined (a) can be welded to each other.

In the synthetic resin welding machine 1, the hot air spray nozzle 31 guides high temperature hot air which is formed so as to be installed at the top end of the hot air supply unit 3 of the synthetic resin welding machine 1, as shown in FIG. 1B. And a discharge portion 31b extending downward from the binding tube portion 31a and discharging high temperature hot air on the surface of the joined portion of the joined object a.

As described above, the hot air spray nozzles 31 are generated from the hot air supply unit 3 and discharged through the discharge unit 31b in a state where the hot air spray nozzles 31 are fitted at the top end of the hot air supply unit 3 as the binding pipe part 31a. The molten resin is melted by the molten resin supply part 4 on the surface of the joined part (a) to be joined in the heat-melted state by heating and melting it on the surface of the joined part of the joined object (a) as hot hot air. The molten resin (b) extruded along the nozzle 41 was welded so as to be welded to each other.

Therefore, the conventional hot air spray nozzle 31 for the conventional synthetic resin welding machine can be recognized that there is no problem in welding by heating the surface of the joined portion of the joined object a by melting it. As the optimum condition for heat treatment, the surface of the joined part (a) was inadequately heated and melted, so that the welded states of the joined parts (a) were not robust and unnecessary during the welding operation. There were drawbacks such as time consuming.

That is, the conventional hot air spray nozzle 31 for a synthetic resin welder is sprayed with hot air (about 400-650 ° C.) that is installed and supplied to the hot air supply unit 3 of the synthetic resin welder 1 to By locally heating the surface of the junction, a volatile retaining layer (a phenomenon in which an oil film is formed on the surface of the bonded object a) is formed on the surface of the heated object to be heated (a). As the surface burns black, a carbonized shape occurs.

Therefore, the molten resin (b), which is extruded from the molten resin supply nozzle 41 of the synthetic resin welding machine 1, is welded to the surface of the bonded portion (a) to which the material properties have already changed, and thus, the bonded object (a) is welded. As the bonding force between the surface of the bonded portion and the molten resin (b) decreases, the poorly welded joined object (a) is easily separated and loosened by a small impact.

In addition, the conventional hot air spray nozzle 31 for a synthetic resin welding machine has a locally heated structure, and since the portion to be heated is extremely limited, the surface of the junction part of the joined object a is uniformly melted with a constant depth. In order to be heated as much as possible, it moves slowly, and as a result, the welding work cannot proceed quickly and the slow working speed (approximately 30 cm per minute) is maintained. There was this.

This study is designed to scrape the molten parts while sufficiently heating and melting the surface of the bonded part of the joined part. First, the welded parts can be welded together more reliably, so that the reliability of the welded part can be achieved. Secondly, the object of the present invention is to provide a hot air spray nozzle for a synthetic resin welder, which can significantly improve the work efficiency by enabling the welding work of the joined object to be performed relatively quickly.
