Description

Technical Field

[0001] The utility model relates to the technical field of welding devices, in particular to an extruded plastic welding device. Background Art

[0002] Extruded plastics include plastic pipes, plastic sheets, plastic films, plastic strips, rods, profiles, plastic profiles and plastic product accessories. During the processing of extruded plastics, two or more plastic parts need to be bonded together by heating and pressurizing with a welding device. Current welding devices will produce certain toxic and harmful gases when bonding extruded plastics. Long-term inhalation of these gases by workers can have a certain impact on their health.

[0003] Therefore, in order to solve the above problems, the utility model with patent announcement number CN221808839U discloses a plastic welding machine, which has a smoke shield arranged on the outer periphery of the output shaft close to the welding head, and an air intake pipe arranged on the side of the smoke shield away from the welding head. The air intake pipe passes through the smoke shield and extends to the interior of the smoke shield. An exhaust fan is arranged at the end of the air intake pipe away from the smoke shield, and a filtering device is arranged on the side of the exhaust fan away from the air intake pipe to solve the toxic and harmful gases generated during bonding of the plastic welding machine. Although it is convenient to reduce the toxic and harmful gases generated during welding, the temperature of the welding part of the extruded plastic is high after welding, and it takes a certain amount of time to cool down. Direct transportation is likely to cause instability of the welding part, which will affect the final welding effect of the extruded plastic. Utility Model Content
