Automatic quantitative powder packaging machine 5 common problems and solutions

April 22, 2020

Powder packaging machine is widely used in food, medicine and chemical products in the viscous or non-viscous powder material automatic packaging.In recent years, with the rapid development of medicine, food and other industries, powder packaging machine market still maintains a high growth rate, and domestic powder packaging machine basic technology, innovation ability, promotion ability and service ability continue to improve, gradually favored by more fields.
The industry said, powder packaging machine with automatic quantitative function, according to the needs of users can be quantitative production, to meet the large-scale production needs of customers, reduce investment costs for customers.However, in the actual operation of the powder packaging machine, there are often some failures, it is worth the user to understand and master the solution.
Start the problem
Many users are using powder packaging machine, found that suddenly can not start automatic program.All you need to do in this case is do a check.First, check whether the feeding cylinder is closed. If the cylinder is closed, whether the position sensor is loose and in place.
The industry pointed out that if the sensor location is not correct, the permanent magnet in the cylinder magnetic weakening, causing the signal out of control, resulting in automatic procedures do not start.If the sensor position cannot be adjusted, the sensor output line can be short-circuited.
Display problem
The weighing accuracy of powder packaging machine is very important.However, a lot of packaging will appear on the weight display values are unstable, ups and downs.In this case, it is generally necessary to exclude the vibration phenomenon of powder quantitative packaging machine, in addition to check whether the voltage is stable, body grounding resistance meets the requirements, and so on, to keep the display value of the display stable.
Super bad serious
If the user in the use of powder packaging machine found that the weight of the material is unstable, out of tolerance phenomenon.We need to check if it is the case that the oil road is blocked.
The industry says, when the oil road is blocked, will cause the cylinder seal rubber gasket and cylinder block dry grinding and damaged, resulting in gas, thus affecting the cylinder at all levels of feeding trip."In this case, the main cylinder can be replaced with a two-stage rubber washer while unclogging the oil line."
The hopper leaks material
The material leakage of the hopper is directly related to the fault of the feeding mechanism. What needs to be done is to clear the accumulated material in the hopper first, and observe whether the feeding cylinder is in place and whether the door valve has accumulated material.If the above are normal, it should be checked whether the sealing of the feeding cylinder is good.
There is an adjusting screw in the lower part of the feeding cylinder. When the adjusting screw hole is blocked, there will be a delay of closing the door and the leakage of materials.If this is the case, it is necessary to dredge the air hole in time.
Bag clamping mechanism does not work
Technical personnel said, if you don't action folder bag institutions, the electric conversion valve didn't work properly, the air source pressure under normal circumstances, first check the reversing valve coil voltage can be controlled, if electrical conversion to normal for reversing valve fault, should change in time, if you can't switch, the corresponding maintenance process for clip bag triode switch, reversing valve control, two-way trigger photoelectric coupler.
