Color mark matching method and adjustment of pillow packaging machine

Color mark matching method and adjustment of pillow packaging machine In order to ensure the automatic positioning of packaging, it is necessary to control the servo motor M2 to synchronize the feeding speed with the incision speed of the horizontal head. However, for a system designed to be synchronous, the original synchronous system will be out of synchronization due to the occasional fluctuation of operation and operation disturbance. Therefore, it is necessary to add a color mark detection and control circuit in the basic synchronous system, to correct at any time, and to continuously perform error compensation. To ensure that the cutting and sealing position remains unchanged, this requires the use of the color code on the wrapping paper to complete the positioning. Color mark positioning and benchmarking put forward certain requirements on packaging materials, photoelectric detection methods, and color mark printing. As far as the packaging material is concerned, it is required to have a high density, a uniform thickness, and a certain tensile strength. There are two types of photoelectric detection methods, transmission type and reflection type, according to different packaging materials. The transmission type is mostly used for the detection of transparent packaging materials, while the reflective type is used for the detection of packaging materials that are difficult to transmit or cannot transmit light. Usually high-speed packaging machine design, most of the use of reflective photoelectric detection method, because it has a higher detection sensitivity. For the color mark printing requirements, the positioning color mark must have the function of shading or light-transmitting. At the same time, with the size of the packaged product and the detection method, the positioning color mark must have enough shading area to ensure the reliability of the signal during photoelectric detection. . With good packaging materials, proper positioning of the color mark and the correct method of measuring the color mark with the photoelectric shading reflective sensor, the color mark can be calibrated and adjusted.
