Automatic feeding system flow

Raw materials → storage → dehumidification drying → metering mixing → transportation → use

Automatic feeding system process using a machine a tube, sealed circuit design, to ensure the stability of the entire system, no plastic resurgence, blocking material phenomenon occurred. It is used in conjunction with a central dryer (dehumidifier) system to allow dry air to dry the raw material again to prevent moisture from resurfacing. The automatic feeding system guides the flow of the process and cleans the conveyor tube after each conveyance cycle. There is no residue in the pipe. In order to avoid the return of raw materials, but also to ensure that the injection molding machine to join the consistency of raw materials in the vacuum negative pressure with the role of the original raw materials through the filter (dust collector) system filter out, favorable to improve product quality.Automatic feeding system flow
How to quantify the automatic feeding system process This is a very important issue, according to the amount of material feedback to the quantitative pulse signal flow signal, when the material reaches a certain value, the instrument system will give the solenoid valve Or a pump to absorb a good switch, so as to achieve the valve, the pump start and shut down the control, so as to achieve the false control of manual control good automation, automatic feeding system, high precision, easy to operate, very easy to achieve, on Automatic feeding system, the quantitative process of the problem, Da Aetai plastic machinery Xiaobian to tell you about:

1, recovery button: record a sudden power failure or other causes of quantitative control stop halfway, press the resume button can continue to join the incomplete value of the value.
2, the start button: the central feeding system after each operation is completed, press this key to clear the value, restart the next batch of operations.

3, stop the key: the central feeding system if you encounter an emergency situation, you can press this button to stop the valve.

4, the meter: you can set the amount of the required amount of material, the meter control instrument switch signal output, when set a good value, the instrument system will give the solenoid valve or pump A switch signal that automatically closes the pump or valve when the set value is reached. With the instantaneous flow, the cumulative flow, the central feeding system to add the amount of display function controller with a panel clear device.


Automatic feeding system flowIndustrial development is rapid, the enterprise for the equipment production efficiency requirements are higher, the molding machine for the material also tends to automation, intelligent and human control, feed is divided into automatic feeding system and single feeding method, and the current business use up The automatic feeding system is more able to meet the production requirements of enterprises. Automatic feed system process is designed for the plastics industry, not only can improve production efficiency also saves equipment costs, compared with the single machine, more application advantages.
But the automatic feeding system maintenance is not timely there will be some minor problems, following the company's technical staff to the commonly used customers to provide a number of feasible solutions, saving more trouble.
Automatic feeding system process failure and troubleshooting:

Automatic feeding system flowAutomatic feeding system failure and troubleshooting method
Method of exclusion
1 centralized feeding system failure and troubleshooting method failure situation centralized feeding system can not boot
① Check whether the power supply 380V, electric control box switch is open
② check the fuse is blown, check the reasons for the blow
③ check the transformer is normal
④ check the switching power supply is normal
2
Automatic feeding system failure and troubleshooting method The fault screen has a display
But can not start the fan
① Check whether the switch of each suction bucket is open and operate in the setting screen
② Check whether the fan is overloaded
③ check the electronic control box within the relay is normal
④ whether there is reverse power supply
3
Automatic feeding system failure and troubleshooting failure conditions have suction action, but no suction or suction is not smooth
① check the negative pressure pipe in the windshield valve is leaky
② Check whether the filter in the dust collector is blocked by dust
③ Check the exhaust dust on the dust collector
④ Check the suction bucket cover is covered
4
Automatic feeding system flowAutomatic feeding system failure and troubleshooting method failure of a boot insurance on the fuse
① check whether there is a short circuit
② check that part of the insurance burned to check that part of the circuit
③ check the valve solenoid valve whether there is a short circuit
④ Check whether the solenoid valve has a short circuit
5
Automatic feeding system failure and troubleshooting method failure on the machine suction tank no material
But the touch screen shows full material
① Check the sensitivity of the photoelectric switch is normal, with or without damage
② Check the photoelectric switch is not on the official or the screw is not tightened
③ Check if the air plug is plugged in
6
Automatic feeding system failure and troubleshooting method failure on the machine suction tank no material
But the touch screen shows no shortage of material
① Check the sensitivity of the photoelectric switch is normal, with or without damage
② Check the photoelectric switch is not on the official or the screw is not tightened
③ Check if the air plug is plugged in
7
Automatic feeding system failure and troubleshooting method failure situation drying bucket shortage material, abnormal
① check the dry bucket on the micro-moving hopper micro-switch is normal
② Check whether the raw material barrels of raw materials, raw material barrels with raw materials
8
Automatic feeding system failure and troubleshooting failure will not automatically sucking
① Check the "set the screen" of the barrel switch is open
② Check the sensitivity of the photoelectric switch is normal
③ check the choice of raw materials is correct
④ Check whether the pumping time and the evacuation time are set correctly
⑤ Check the compressed air supply is normal, at 4KG / cm2
⑥ Check the machine's windshield valve, cut off the valve cylinder and solenoid valve is normal
9
Automatic feeding system failure method Failure condition Vacuum suction bucket does not fall blank
① open the suction bucket is covered to see whether the original fried bridge, stuck in the blanking mouth
② check the evacuation time is too long
③ Check whether the pumping time is too long
10
Fan overload
① whether the normal power supply voltage 380V
② Check the contactor and thermal relay is normal
③ Check the exhaust valve and fan selection valve is normal
④ check the pipeline is blocked, resulting in the load is too large
⑤ check whether the fan stuck, measuring the resistance of the fan is normal
11
The fan does not start
① Check whether the switch of each sucker bucket is open and operate in the setting screen
② check the electronic control box inside the relay is normal
③ check all the sucking bucket are full of state
④ Check whether the fan is set to manual
12
The machine sucks the bucket
① Check whether the dry barrel is free of raw materials
② Check the raw pipe number selection is correct
③ check the selection of the station on the tube is connected
④ Check the sensitivity of the photoelectric switch is normal
