Ambito di applicazione dell'appalto
Breve descrizione:
The Mix-Extruder machine is a one-stand that must incorporates and enables the consequent actions of milling and extruding. Initially, it must be able to mix continuously a seamless rubber strip, of variable dimensions, by way of two independent driven rollers with hydraulically adjustable gab. The intake of the machine must be equipped with an automated dosing system in order to charge additives in the rubber bank, which may come in different formats: powder, pellets and pre-dispersed rubber wands. Subsequently, the machine must extrude the compound with a rightly designed plasticizing screw and thrust it through a flat-die extrusion head for a finite sheet of dimensions 750mm x 8mm. The machine design must be suitable for completely hands-off operations. All parts of the Mix-Extruder must be dimensioned fitly to withstand the pressure and the wear caused by the rubber in a continuous operations manufacturing environment: a minimum throughput rate of 2500kg or rubber per hour shall be accepted.
Mostra di piรน
The Mix-Extruder machine must be provided with safety covers, electric locks on doors (if necessary) and light barriers to prevent the operators from entering or reaching possibly dangerous area, adopting the necessary Health and Safety requirements appointed in the latest EU Machinery Directive.
Mostra di piรน
Milling modules: the rubber strip is received by two cylinders ร˜=250mm x L=600mm, independently driven for high and stable friction ratios. Each cylinder features grinded surface (Ra=0,8), chromium plating (thickness at least= 35ฮผm) and peripherals bores for water temperature control. The cylinders opening is provided by two hydraulic pistons (integrated in the stands) which must be able to move and precisely regulating the milling gap; the hydraulic movement unit must also ensure the safety emergency opening as normed. The module must integrate controls for the cylinders scrapers and stock guides.

Extruding module: the screw is made of hard nitriding steel, the armoured flights profile must be designed to ensure plasticizing at a variable speed of 5โ€“45rpm. The screw has dimension 250W x 9L/D and is deep bored for forced-water temperature control. The extruder barrel is bimetallic, in between the inner liner and outer supporting structure, a helical tunnel ensure water circulation for an optimum-distributed temperature control zone.
Mostra di piรน
Extruding head: it is designed to optimise and uniform the distribution of the rubber, coming from the plasticizing screw, into a finite sheet with stable dimensions of 750mm x 8mm. The flat-die head is composed by two pieces: the lower is the main unit and it is fixed on the extruder barrel, the upper can be hydraulically opened for maintenance. Both parts of the extruding head features a grid of deep borings to allow a diffused forced-water temperature control. During extruding operations, the two parts are firmly locked by the means of hydraulically actuated latches.
