The packaging machine is a prevalent equipment. The automatic contraction packaging machine is mainly the equipment for mechanized development. What is the common problem of automatic contraction packaging machine in the process of using it? The following packaging machine manufacturers Shanghai Bofi will introduce you and provide some maintenance.
First, approach switch fault:
The shrink machine packaging machine has five proximity switches. 3 is used in knife protection, and 2 is used in the use of an apparatus motor capable of controlling the upper and lower films. When the control knife is protected, one or two misunderstandings may occur, so there will be a situation in which normal work is interrupted, and because there is a small number of problems, and the time is short, the problematic analysis also has exclusions. There must be difficult.
Maintenance method: You can install the same type switch in parallel with the rising switch of the molten knife, and work in parallel in parallel, which can enhance its reliability.
Second, magnetic switch fault:
The magnetic switch is used to detect the position of the cylinder and the stroke of the cylinder. The laminate, push bag, compression package, and fused cylinder movements are associated with each other, and the positions are detected and controlled with magnetic switches. The fault is mainly manifested as a follow-up cylinder, because the cylinder speed is faster, causing the magnetic switch to detect the signal. If the push pack cylinder speed is too fast, the push package is reset, the press is not moved.
Maintenance method: Adjustable cylinder and its two-position five-way solenoid valve, adjust the compressed air flow, reduce the operating speed of the cylinder until the magnetic switch can detect signals.
Third, solenoid valve fault:
The problem that the electromagnetic valve appears mainly is to manifest the cylinder that does not move or does not reset, because the cylinder solenoid valve cannot be reversed or is helium.
If the electromagnetic valve appears to be qi, because the input air path is connected, the pressure of the machine air pressure cannot reach the pressure of the work, and the beam is not in place. The protection of the tool beam will approach the switch does not work, the conditions for the operation of the whole machine are not established, and the machine is not able to run, which is very easy to confuse the electrical problem.
