Abstract: A device to prevent the drying of nozzles of a machine for the preparation of fluid coloring products having a delivery head includes an anti-drying member and an actuation mechanism to take the anti-drying member from an inactive position distant from the delivery head to an operating position in contact with the delivery head. The actuation mechanism includes an actuation lever oscillating with respect to a fixed support and a group of parallelogram levers commanded by the actuation lever and connected to the anti-drying member so as to keep an upper surface of the anti-drying member constantly parallel to the lower surface of the delivery head during the movement from the inactive position to the operating position.

Abstract: A positioning and support device for tanks of fluid coloring products, comprising a plate having a plurality of through apertures into which the tanks are suitable to be inserted from above. Snap-in attachment elements are provided in correspondence with each of the through apertures to cooperate with one of the tanks and keep it positioned, at least temporarily, inside the corresponding through aperture.

Abstract: A perforation device to perforate closed receptacles containing coloring products is provided, and includes a support plane which is configured to support a receptacle to be perforated. The support plane is movable in a substantially vertical direction. The perforation device also includes a perforation member positioned at a determinate height, higher than the support plane, and an actuator to selectively move the support plane toward the perforation member to cause the perforation of the receptacle to be perforated. The actuator includes a lifting mechanism connected to the support plane and drivable by a pedal that cannot be driven by an operator without the operator also driving a safety mechanism at the same time using both hands.

Abstract: Distribution device for coloring products, comprising a collector for dispensing nozzles and corresponding nozzles mounted thereon. The collector comprises a containing body provided with one or more through cavities. In correspondence with one end associated to an external surface the containing body is provided with a positioning element. The containing body is provided with a seating, inside the external surface, disposed at the end of each of the through cavities, defining a wider portion with respect to the cross section of the corresponding through cavity.

Abstract: Machine and method for dispensing fluid coloring products, each having a different color, to form a finished product having a desired color tone corresponding to a determinate formula, wherein an electronic control circuit comprises a central process unit and two electronic actuation circuits, each configured to be selectively associated to each motorized pumping member of the delivery circuits, so as to selectively cause the simultaneous drive of two motorized pumping members. The central process unit is programmed so as to reduce to a minimum the overall delivery time, by selectively coupling each of the two electronic actuation circuits to one of the motorized pumping members, as a function of the formula corresponding to the desired color tone.

Abstract: Perforation device to perforate closed receptacles containing coloring products, comprising a support plane, movable in a substantially vertical direction and on which a receptacle to be perforated is suitable to be disposed, a perforation member positioned at a determinate height, higher than the support plane, and actuation means to selectively move the support plane toward the perforation member to cause the perforation of the receptacle to be perforated. The actuation means comprise a lifting mechanism connected to the support plane and drivable by means of a pedal from being driven by an operator without the latter also driving said safety mechanism at the same time and with both hands.
