Rotary plastic welding machine, usually for two circular thermoplastic welding of the workpiece, a workpiece is fixed on the bottom die, the other a workpiece is fixed on the rotating spindle in precision servo fixture, because a certain pressure on the two parts, through the round shaped part of two high speed rotary friction make up / down the workpiece made contact surface friction heating, the mechanical energy is converted into heat energy, contact surface melting after the pressure of instant stop in a set position, the upper and lower two, makes the workpiece welded together into a fusion of permanent and form a fastening and closed the whole, reach the requirement of welding. Application of thermoplastic PE, PP, hot melt nylon round product welding, also from the workpiece size and material constraints.
Rotary plastic welding machine is characterized by: welding by low density, high melting point material injection molding of large volume of plastic parts, simple operation, high strength, good appearance quality, high production efficiency, can meet the water tightness and air tightness of the high strength requirements.
The main characteristics of:
1, the rotation of the main shaft is driven by a precision servo motor, high torque output, with angular rotation precision control precision positioning in less than 1 degrees.
2, the process control by using the programmable controller (PLC), provides all the control and function requirement.
3, LCD touch screen control panel, human-computer interaction interface, set and adjust the welding parameters: pressure, rotational speed (RPM), R / cycle (RPC), welding time, holding pressure time. By monitoring the RPM, RPC, torque and other parameters to control the welding quality.
4, two kinds of welding mode: set time welding mode / speed welding mode, which can meet the requirements of positioning or positioning welding. The precise control of speed (RPM), big / small size circular plastic workpiece welding general.
Precision design and structure design of a transmission mechanism 5, high rigidity, effectively prevent the machine start / shock instantaneous stop time, high reliability, durability.
6, convenient and quick die change design, precision adjustment of welding mould.
