Problems solved by technology

Because of its two clamp devices, one is fixed and the other is movable under the action of the feed device of the clamp, so this welding device often rubs the welding surface of the profile during welding, so it is easy to cause the welding corner strength of the profile to be low and unstable problem
Since the height of the profile support plate of the clamp device cannot be adjusted, the profile support plate needs to be replaced for profiles of different heights, so this welding device also has the disadvantages of complicated operation procedures and low processing efficiency
Because its welding melting amount limiting mechanism is composed of limiting cylinders, etc., its positioning device and heating device are independent, and its heating plate must have a floating device that makes the welding heating melting amount equal on both sides to be heated. There are disadvantages such as unstable profile positioning, large human influence, uneven heating and melting on both sides of the heating plate, easy to cause poor welding quality of profiles, uncompact and complex structure, and unfavorable for manufacturing and maintenance.

Abstract

The welding device of plastic door and window welding machine relates to a mechanism of plastic door and window welding machine. Said mechanism includes two holddown pliers devices, positioning heating device and welding melting spacing mechanism, the described two holddown pliers devices are respectively equipped with a set of sliding mechanism fixedly-connected with them, and the described two sliding mechanisms are connected with holddown pliers feeding devices capable of synchromoving with them. Said invention is mainly used on plastic door and window welding machine.

Description

Technical field [0001] The invention relates to a mechanism of a plastic door and window welding machine, in particular to a welding device. Background technique [0002] At present, the welding device of the plastic door and window welding machine mainly includes two press clamp devices, a press clamp feed device, a positioning device, a heating device and a welding melting amount limiting mechanism. Because of its two clamp devices, one is fixed and the other is movable under the action of the feed device of the clamp, so this welding device often rubs the welding surface of the profile during welding, so it is easy to cause the welding corner strength of the profile to be low and unstable issues. Because the height of the profile backing plate of the clamp device is not adjustable, the profile backing plate needs to be replaced for profiles of different heights, so this welding device also has the disadvantages of complicated operation procedures and low processing effic...
