Model HN 100 HOT MICRO PERFORATION system for holes from 200µ to 2mm with motorized needle roller of Ø100mm
Description
This equipment is designed to make "hot" micro holes on moving film of various materials and thicknesses and is to be inserted as a host unit in film processing lines, such as slitters, extruders, printing and welding machines. The HN100 is a motorized unit with an automatic synchronization system that ensures perfect micro holes on a variety of materials; ideal for delicate processing on shrinkable and non-woven materials; for processing requiring holes with very high needle density per cm²; and for processing mono- or bi-oriented materials.
Operation
The HN100 is an electrically heated hot needle micro-perforator.
The running film arrives at the machine and passes through the heated motorized needle roller and the counter roller, which approach each other and perforate the material. The rollers are approached through the pneumatic system, and the perforation adjustment is implemented by two micrometer screws.
OPERATION CONTROL of the HN100 is entrusted to our software designed for 4.0 integration from the electrical control panel. The operator via touch screen manages all operations inherent to the device such as temperature control, control of heating elements, emergency activation and needle shaft rotation.
When the device is paused, the needle shaft rotates slowly to maintain a uniform heating or cooling temperature to avoid any damage.
In "automatic function," the approach of the counter roller to the needle shaft is enabled only at optimum film running speed and temperature, to ensure perfect holes and to prevent, due to wrong temperature or slow film running, material melting on the needles.
When the operator activates the perforation "stop" function or the film is running at an unsuitable speed, the perforation is disabled: the counter roller with the running material moves away, the shutter separating the hot chamber drops, and the unit goes into "pause" mode, with the needle shaft continuing rotation at reduced speed. A "manual function" is still available, however, allowing the operator to activate perforation at any speed the film is running.
It is possible to equip the device with a photocell reading the material presence, so that when no material is detected it disables perforation and closes the shutter.
When the machine is turned off, it enters the "pause" mode before stopping, continuing the rotation of the needle shaft until it cools down, to prevent needle damage and roller twisting.
Components
1 Needle shaft
It consists of a STEEL ROLLER with mechanical parts SUITABLE FOR WORKING AT HIGH TEMPERATURES to prevent damage from thermal expansion.
2 Counter roller
It has a PERFECTLY UNIFORM SURFACE to obtain homogeneous holes. It can be supplied in rectified natural bristles, plastic bristles or rubber.
It is driven by pneumatic system, and enables and disables perforation by approaching or moving away from the needle shaft
3 Electric heating system
It consists of a group of lamps (INFRARED CERAMIC RADIATORS) with PID control. The PLC manages the three heating lines independently so as to ensure uniformity of heat emission. The operator can monitor the temperature inside the chamber via touch screen.
4 Shutter
Moved by two pneumatic pistons, it is part of the safety systems: it separates the insulated chamber from the counter roller and the film to be processed, preventing the material from catching fire
5 Interchangeable cylinders
Bronze or steel sectors with infixed needles. They are mounted on the needle shaft.
6 Micrometric screws
They are part of the PENETRATION ADJUSTMENT SYSTEM, and are used to adjust the distance between the counter roller and the needle roller.
7 Idler rollers
Made of steel, they are part of the TRANSFER GROUP for optimal control of the tension of the film to be processed.
8 Insulated chamber
Stainless steel plate chamber containing the motorized steel shaft, ceramic lamps for heating, and cushions for thermal insulation.
