The temperature control of the thermostat consists of the following parts:
Heating part: heating the thermostatic bath with an electric heating tube. Temperature measuring part: Generally, industrial platinum thermal resistance is used as the temperature measuring element, and the measured temperature value is converted into a corresponding resistance signal to the matching display adjustment instrument to display the temperature in the thermostatic bath. Adjustment control part: The temperature display adjustment instrument performs PID (proportional, integral, derivative) adjustment according to the difference between the measured temperature in the constant temperature bath and the set temperature to control the conduction angle of the thyristor to control the heating power of the electric heating tube, The heating power changes with the temperature difference. When the set temperature is reached, the regulator balances the heat generated by the heating tube and the lost heat through the thyristor, so as to achieve the purpose of constant temperature.
There is also an adjustment control part. When the temperature in the constant temperature bath is lower than the set temperature, the output signal of the temperature display adjustment instrument controls the relay to turn on the heating tube, and when the temperature is higher than the set temperature, the control indicator of the temperature display adjustment instrument is turned off. The heating tube stops heating to achieve the purpose of constant temperature. However, due to the thermal inertia of the heating tube in this control method, the temperature in the constant temperature bath fluctuates greatly above and below the set temperature, and the constant temperature effect is not as good as above.
The rotary arm wrappers are mainly used for the high speed packaging/logistic system. according to different packaging line, the Rotary Arm Wrapper can be designed for loads small or big, light or heavy.
It refers to rotate the goods around the rotary arm, thereby achieving wrapped the goods. All T-series wrappers can be wrapped with R-Series wrappers. In addition, the wrapping methods is more suitable for lighter, higher-level and unstable post-palletizing products or overweight goods. Flexible installation of the machine can be placed on the wall, can also be used to support fixed; and can be connected with the transmission line as needed to meet the demands of assembly line operations.
