Abstract

The invention belongs to the technical field of hot gas plastic welding and provides a sealed type hot gas welding unit and plastic welding equipment comprising the same. The sealed type hot gas welding unit comprises a welding pipe part, a gas charging component and a heating tube, wherein the air charging component is connected to the welding pipe part; the heating tube is connected within the welding pipe part, and the two ends of the heating tube are sealed; the welding pipe part comprises a first pipe part and a second pipe part which is connected within the first pipe part; a heat insulating layer is arranged between the first pipe part and the second pipe part; the air charging component communicates with the second pipe part; the heating tube is positioned inside the second pipe part; the outer tube wall of the heating tube clings to the inner wall of the second pipe part; a thread groove is concavely formed in the outer tube wall of the heating tube. By the design, the sealed type hot gas welding unit disclosed by the invention is capable of solving the problems that the existing welding equipment is low in heat utilization rate, the temperature of exhausted gas is not high enough because of short contact time between cold gas and a heating unit, and therefore the welding efficiency is affected.

Description

technical field [0001] The invention belongs to the technical field of hot air plastic welding, and in particular relates to a sealed hot air welding unit and plastic welding equipment with the welding unit. Background technique [0002] Hot air welding refers to heating the metal welding head through the heated air flow to heat-melt punch or connect the plastic parts, and then a single or multiple hot air welding units will be set on the hot air welding equipment to meet the actual production needs. The existing A heating unit is set in the hot air welding unit to heat the incoming gas and export it out. During this process, the heat loss due to heat radiation and heat dissipation is large, resulting in a low overall heat utilization rate. At the same time, the contact time between the incoming cold air and the heating unit is short, resulting in When the temperature is not enough, it will affect the efficiency of welding. Contents of the invention [0003] The object of...
