Model CN-M COLD MICRO PERFORATION system for holes from 80µ to 1mm with motorized needle rolls of Ø 100mm - 150mm - 200mm
Description
CN SERIES MICRO-HOLE PERFORATORS are light and versatile models with REDUCED DIMENSIONS, designed to make MICRO-HOLES of various diameters on MOVING MATERIAL, to be inserted as host units in film processing lines such as slitters, extruders, printing machines or welding machines, and on all production lines that process MOVING FILM. Suitable for making micro holes for vegetable and fruit bags, thermal and acoustic insulation, packaging of electronic products, breathable film, etc.
Operation
The running film arrives at the device and passes between the motorized needle shaft and the contrast roller, which come in contact and perforate the material. The contrast roller is moved through the pneumatic system and the penetration level is adjusted by two micrometric screws. The operation control is entrusted to the software designed for 4.0 integration: The operator manages all the operations of the device via touch screen on the electric control panel. The operating system is simple, practical and quick to use and facilitates all work phases. The movement of the needle shaft is driven by the asynchronous motor and encoder, with a "tracking" function that synchronizes the machine to the speed of the host line.
Components
1: Needle shaft; 2: Counter roller; 3: Idler rollers; 4: Micrometer screws; 5: Interchangeable cylinders; 6: Asynchronous motor with driver and encoder.
Needle Shaft (1)
It consists of a steel roller on which cylinders (5) are mounted, which can be spaced to micro-perforate multiple tracks in the material, or adjacent to each other to perforate the entire usable surface of the film. It is designed to ensure quick and easy replacement of the cylinders (required for processing changes).
Counter roller (2)
It has a perfectly uniform surface that allows for the homogeneity of the holes made and can be supplied in ground natural bristles, plastic bristles or rubber. It is pneumatically driven, allowing it to be moved closer to or farther away from the needle shaft, thus deciding whether to enable or disable perforation.
Idler rollers (3)
These are two steel rollers and make up the idler unit, designed to ensure optimum control of the tension of the film to be processed. The position and number of rollers varies according to the needs, and can be agreed when ordering.
Micrometric screws (4)
They are part of the penetration adjustment system, and are used to adjust the distance between the counter roller and the needle roller, setting the penetration of the needles into the material and consequently the diameter of the hole to be made. The adjustment can be made either with the machine stopped or with the machine in the process of working.
Interchangeable cylinders (5)
Bronze, steel or nylon sectors with needles infixed. They are mounted on the needle shaft (1). Holes of a minimum Ø of 80µ and a maximum Ø of 1mm are made.
Asynchronous motor with driver and encoder (6)
It moves the needle shaft and has a "tracking" function that allows the rotation to be synchronized with the speed of the film flow and thus with the speed of the host line, thus avoiding stretching of the material and achieving flawless holes even with the most difficult materials and at high needle density per cm².
