Abstract

This product is a special material for the hot melt forming a mechanical and electrical, PLC technology as one of the automation equipment, equipment mainly feeding device, electric heating device and pressure reduction device and other major components, feeding device with cylinder drive , Guide rail guide, stroke block positioning, its role is to be equipped with the next mold sent to the processing position. The electric heating device is provided with electric heating device, which is electrically heated to the upper mold with good thermal conductivity and is driven by pressing the cylinder. The fitting is hot-melted and the operator only needs to put the fitting into the lower mold, , Automatic hot melt molding, you can get a good product, improve the productivity and reduce the labor intensity, this paper on the automatic hot melt forming device for the overall layout of the main components of the program, the feed cylinder, clamping cylinder , Press the cylinder, rail and other major parts of the design calculation and selection, and developed a pneumatic system. The structural characteristics of the device are analyzed and elaborated and the PLC program is compiled.

Key words: hot melt electric heating forming pneumatic automatic
