Horiztonal flow wrap packing machine operation process

The flow wrap packaging machine is not only a continuous packaging machine suitable for various specifications of food and non-food packaging. It can be used not only for the packaging of non-brand packaging materials, but also for high-speed packaging of roll materials pre-printed with logo patterns. In packaging production, due to the influence of factors such as the error between the positioning color marks printed on the packaging material, the stretching of the packaging material, and mechanical transmission, the predetermined sealing and cutting positions on the packaging material may deviate from the correct position, thus Error occurs.In order to eliminate errors and achieve correct sealing and cutting, packaging design must consider automatic positioning. Most of the methods to solve this problem are to complete the design of continuous photoelectric automatic positioning system based on the positioning marks of packaging materials. The continuous photoelectric positioning system is divided into two types of transmission systems: front-rear type, braking type and synchronous type according to the error compensation working mode.

In order to ensure the automatic positioning of the packaging, the servo motor M2 needs to be controlled to synchronize the paper feeding speed with the cutting speed of the horizontal head. However, for systems designed to be synchronized, the original synchronized system will be out of sync due to factors such as unexpected fluctuations in operation and operational interference. Therefore, it is necessary to add a color mark detection and control circuit to the basically synchronized system to correct at any time. and continuously perform error compensation. To ensure that the cutting and sealing positions remain constant, positioning is done with the help of color codes on the wrapping paper.Color mark positioning places certain requirements on packaging materials, photoelectric detection methods, color mark printing, etc. As far as packaging materials are concerned, they require higher density, uniform thickness, and certain stretch resistance. Depending on the packaging material, there are two types of photoelectric detection methods: inductive and reflective. The transmission type detects more packaging materials than transparent ones, while the reflective type is used to detect packaging materials that are difficult or unable to transmit light.Usually, the design of high-speed packaging machines mostly adopts the reflective photoelectric detection method because of its high detection sensitivity. For color mark printing requirements, the positioning color mark must have the function of shading or transmitting light. At the same time, it will change with the size and size of the packaged product. Depending on the detection method, the positioning of the color mark must have sufficient shadow area to ensure the reliability of the signal during the photoelectric detection process.

With the improvement of automation, the operation, maintenance and daily maintenance of automatic packaging machines have become more convenient and simpler, reducing the professional skill requirements for operators. Whether the quality of product packaging is good or bad directly affects

It is closely related to the temperature system, host speed accuracy and tracking system stability.
