400 Ton China Made 2RT Rubber Injection Molding MachineAll In All Out
Heat Plates Advantages for injection Machine:
- The upper and lower heating plates of the vulcanizer are three-in-one, and the structure is simple and easy to install.
- The upper and lower heating plates of the vulcanizer supply heat evenly. After entering the heat preservation stage for 10 minutes, the temperature difference between the working faces is only ±3°C～4°C, which exceeds the international standard.
- The upper and lower heating plates of the vulcanizer are small in size, light in weight, and light in weight. The energy consumption is low and the temperature rises quickly. After heating, the whole plate has considerable flexibility. It is tighter than the conventional machine. Under 1.5mpa pressure, it is parallel. It is not more than 0.03mm tightly, and it is generally not available in conventional machines.
- vulcanized glue or repair once formed, the bonding site is smooth, smooth, and the fastness is no different from the original tape.
- The time from normal temperature to vulcanization temperature (145 °C) is not more than 25 min, the power is half lower than that of the same industry at home and abroad, and energy saving effect.
Machine Program Basic Question & it's Solutions:
The control system of the flat vulcanizing machine is composed of a three-needle recorder and a timing controller and a pipeline portion that control the mold temperature. The following small series talks about the problems and solutions that often occur in the three-needle recorder during use.
Problems and solutions for the three-needle recorder
When the measured pressure is transmitted to the coil spring tube or the temperature measuring probe to sense the temperature change of the measured medium, the free end of the coil spring tube will produce an angular displacement, and the four-bar linkage mechanism can be used to record the measured pressure or temperature. value.
(1) The pointer does not move
1 The pipe is blocked or leaking, and the components must be replaced.
2 The four-bar linkage lever is detached, and the lever should be re-applied.
3 The pointer is off and the pointer is good.
(2) The temperature record indication value decreases day by day. If the temperature indication value decreases day by day, the table should be removed and checked in the calibration room to check whether the measurement range is normal. If it is not normal, the temperature package is leaked and the temperature package should be replaced.
(3) When the temperature pointer moves slowly, the spiral tube is blocked or leaked, and the component should be replaced.
(4) The pointer is not sensitive in a small range. There is dust between the small hole and the steel ball at the connecting part of the tie rod. The friction is large, and it is necessary to clean the steel ball often. The second is to loosen the screw between the zero and the gear, and replace the zero adjustment mechanism.
(5) Recording curve often broken The three-needle recorder uses two kinds of recording pen tips, one is a disposable pen tip, and the other is a hanging bottle with a capillary tip. The former has a very short service life, and some use no water for two or three days. We put a small hole in the top of the nib and then fill it in, so that it can be used for a long time. The latter is also often broken, because the tip of the pen is clogged, the tip of the pen should be cleaned; if the capillary is leaking or leaking, the capillary should be cleaned or replaced; the ink bottle suspension position is too low to find the position of the ink bottle.
(6) The regulator has no output, or the output pressure is small.
1 The pressure of the gas source is less than 0.14MPa, and the gas source pipeline is inspected to reach 0.14MPa.
2 The nozzle end face is dirty, the baffle cover does not cover the nozzle, and the nozzle should be cleaned frequently.
3 The throttle hole in the air circuit board is blocked, or the air circuit board is leaking. The throttle hole should be cleaned and the air circuit board replaced.
4 The amplifier has insufficient magnification and the adjustment screw should be adjusted.
5 The output line is blocked or leaking, and the output line should be cleaned or replaced.
(7) Vulcanizer output is always the largest
The orifice of the orifice is not sealed or leaking, and the throttle is not to be throttled. The manifold should be replaced.
2 The amplifier seat and the steel ball are not tight, and the amplifier should be adjusted or replaced.
3 Input and output lines are reversed, so they should be connected correctly.
(8) External temperature control is unstable
1 Negative feedback nozzle blockage or pipeline leak, always clean the nozzle or replace the pipeline.
2 The position of the proportional rod is not adjusted. The proportional rod should be adjusted repeatedly until the external temperature curve is stable.
