How to realize heat shrinkable packaging on automatic production line

by admin

full automatic contraction is an automatic contraction device which combines pneumatic components and mechanical devices and is controlled by PLC and other peripheral circuits. The actuator of the equipment is a cylinder. Its forward and backward are controlled by two position five way solenoid valve. The working position of the cylinder is detected by the magnetic switch and proximity switch and fed back to the PLC. The PLC sends the control command to the solenoid valve of the corresponding cylinder through the program, so as to control the action of the cylinder. Shrinking machine packaging machine has five proximity switches. Three are used for knife protection and two are used to control the upper and lower film release motors. Among them, for the control of knife protection, the occasional misoperation of one or two times will interrupt the normal operation process, and due to the small number of faults and short time, it will bring some difficulties to the analysis and troubleshooting of faults. The typical performance of the fault is that the melting knife occasionally drops and automatically lifts up when it is not in place. The reason for the failure is that the melting knife does not encounter the quilt in the falling process, and the rising proximity switch of the melting knife loses the signal, just as the knife guard plate contacts the packaged object, the melting knife automatically returns upward

how does the heat shrinkable packaging machine realize heat shrinkable packaging on the automatic production line. It is mainly a plastic material; Pet “shrink film”, this kind of raw material shrinks in case of heat and increases the thickness and strength to realize the tight packaging of goods

this kind of work needs the cooperation between the inking machine and the conveying line ~ ~ ~ you can consult him under the “heat shrinkable machine tiger” in the non-standard forum. Reference: heat shrinkable machine Tiger
