The hot-melt welding machine adopts a plate-type structure and uses an electric heating method. The whole machine is in the form of a frame. It consists of three plates: upper template, lower template and hot template. It is equipped with hot mold, upper and lower plastic cold molds, and the action mode is pneumatic control. It is mainly used for welding of plastic parts such as household appliances, car lights and car dissolvers. According to different plastic parts, the heating power and mold size can be set to realize welding of various plastic workpieces, which is easy to operate and convenient to use.
product description
The device adopts a plate-type structure, and the heat of the heating plate is transferred to the welding surface of the upper and lower plastic heating members by an electric heating method. The surface is melted, and then the heating plate is quickly withdrawn. After heating the upper and lower heating members, the molten surface is fused, solidified and integrated. The whole machine is in the form of a frame. It consists of three plates: upper template, lower template and hot template. It is equipped with hot mold, upper and lower plastic cold molds, and the action mode is pneumatic control. It is mainly used for welding of plastic parts such as household appliances, car lights and car dissolvers. Can be set according to different plastic parts size
Power and mold size enable a variety of plastic workpiece welding, easy to operate, easy to use.
The heating plate consists of two upper and lower blocks and is heated by an electric heating tube. There are two temperature controllers in the machine to control the temperature of the upper and lower molds. When welding, it can be set in the range of 0 to 600 °C according to the actual needs of welding.
The control mode of the device can be divided into manual and automatic control. The manual is a single-piece action, which is mainly used for debugging the mechanism and the mold. After manual debugging, the production is adjusted to automatic. The automatic control system is controlled by a programmable controller (PLC) and a touch screen human-machine interface. The movement of each cylinder is pneumatically driven, which is easy to operate, reliable in performance, compact in size, and improves production efficiency and quality. All polyethylene pipe joints must be connected by electrofusion or hot melt, and mechanical joints must not be used. The joints of the hot melt joint are stronger than the pipe itself. The fittings or connectors are made of plastic and there are no corrosion problems. The choice of pipe connection method depends on the pipe manufacturer's requirements and recommendations, as well as the technology available to the site builder. The hot melt connection first trims, cleans, aligns, and is then heated to its melting point and joined together. In the industry, hot melt technology has two types of hot melt and socket connection.
