The invention discloses a welding head for plastic doors and windows. The welding head comprises a sliding base, a U-shaped casing arranged on the sliding base, a fixed working table, a sliding working table, a positioning device and a heating device; the sliding base comprises a front sliding seat arranged on a front guiding rod in a sleeving manner and a back sliding seat arranged on a back guiding rod; the fixed working table comprises a fixed table top fixedly arranged on the U-shaped casing, a front pressing plate and a front stop block arranged on the fixed table top; the sliding working table comprises a sliding table top glidingly arranged on the U-shaped casing, a back pressing plate and a back stop block fixed on the sliding table top; the sliding table top and the back pressing plate can move forwards and backwards synchronously; the positioning device is arranged between the fixed table top and the sliding table top and can move up and down; and the heating device is arranged between the front pressing plate and the back pressing plate and can move up and down. With the welding head, synchronous heating and welding of mullions can be realized once, and positions of baffles can be adjusted according to the thickness of the to-be-welded doors and windows.
Description
Technical field [0001] The invention relates to the technical field of plastic doors and windows, to a welding device for plastic doors and windows, and in particular to a welding machine head for plastic doors and windows. Background technique [0002] Plastic doors and windows are made of PVC plastic profiles. They have good wind resistance, water resistance and heat preservation characteristics. They are widely used. Welding is an important process in the production of plastic doors and windows. It is important for obtaining reliable performance and beautiful appearance. effect. Existing welders are prone to problems such as low corner strength and easy cracking during the welding process, and most of the existing welding machines are single side fillet welders. The doors and windows of the welding machine are extremely inconvenient, which seriously affects product quality and production efficiency ; Therefore it is necessary to develop a multi-purpose welding machine.
