The powder filling machine is a device that is in direct contact with the product, and the manufacturer has strict requirements for every detail. With the integration of green environmental protection concepts, more green and environmentally friendly powder filling machines have become the mainstream darling. Because the powder product is prone to dust leakage, cross-contamination, environmental pollution and other problems during the filling process, the hard requirements for the powder filling machine are particularly important.
Whether the powder filling machine is semi-automatic or fully automatic, it will encounter failures in different places in the course of use. In the face of the failure of special parts, how can we find the problem and solve it as soon as possible? ?
1. PLC failure in powder filling machine
If the motor is controlled at this point, the fault phenomenon is that after the motor is started, the motor runs, but after the stop signal is issued, the motor does not stop running. When the PLC is powered off, the motor stops running. If this point controls the solenoid valve. The fault phenomenon is that the solenoid valve coil is continuously powered and the cylinder is not reset. If you use an external force to hit the PLC to separate the glue points, you can help determine the fault.
2. The magnetic switch of the powder filling machine is faulty.
The magnetic switch is used to detect the position of the cylinder and control the stroke of the cylinder. The four cylinder actions of lamination, push pack, press pack and melt knife are interrelated and magnetic switches are used to detect and control their position. The main fault is that the subsequent cylinder does not move. The reason is that the cylinder speed of the powder filling machine is faster, which causes the magnetic switch to not detect the signal. If the speed of the push cylinder is too fast, the press pack and the melt knife cylinder will not move after the push pack is reset.
3. Solenoid valve failure of powder filling machine
Solenoid valve failure mainly manifests as the cylinder does not move or does not reset, because the cylinder solenoid valve can not be reversed or helium. If the solenoid valve is suffocating, the air pressure of the machine will not reach the working pressure due to the communication between the inlet and outlet air lines, and the knives will not rise. The tool beam protection proximity switch does not work, the prerequisites for full machine operation are not established, the machine cannot be operated, which is easily confused with electrical faults. There is a leaking sound in the solenoid valve, and the sound source is carefully listened to and the leak point is searched by hand. It is generally easy to find the solenoid valve of the helium gas.
Throughout the filling market, the application of powder filling machines can be said to be quite extensive. Specifically around us can also see: often eaten flour, starch, milk powder, various powdered condiments, mask powder and other powder daily skin care products, etc., with the changes in the whole market of powder products, automatic powder irrigation The installed capacity is also constantly developing, and improving production efficiency has become the key to the development of powder filling machines in the future. Together with the needs of users, with advanced production technology, create different types of packaging equipment. At present, the automatic powder filling machine, bag-type, four-side sealing bag type, quantitative type and other types of powder filling machine are available for users to choose. In addition to ensuring product quality, powder filling machines have to work harder to improve production efficiency.
