摘要:
Dosage valve for a fluid product, for example a colorant, comprising an at least partly elastic or elastomer element (11), having at least a cut (24) in the central part (12) so as to define at least two closed/open cooperating lips (14), which comprises a sensor element (30) associated with the at least partly elastic element (11) in order to detect at least a closed or open condition of the lips (14).
摘要:
Containing device for containing and correctly holding a closed container (11) for fluid products inside a mixing machine (12) for said fluid products. The containing device comprises a container element (13) provided with at least a lateral wall (14) that defines a compartment (24), which is open and accessible from above, has a longitudinal axis (X) in the center and in which the container (11) is able to be disposed with play. Radial pressure elements (15) are disposed on substantially opposite sides with respect to the longitudinal axis (X) and are movable in synchrony in order to selectively clamp the container (11) in a central position inside the compartment (24).
摘要:
A machine structure, in particular for the processing of fluid products, comprises a loadbearing frame with vertical uprights (12) connected by two horizontal plates (14,15) at a distance from each other. Between the uprights are located one or more removable covering panels (13) which cover the zone housing the machine components. The machine structure is strong but light, not very bulky and easy to assemble even by non-specialist personnel.
摘要:
A positive-displacement pump, in particular for use in machines for dispensing fluids, comprises two elements that are rotatable with respect to one another and which mesh with one another (20, 30), each of them being rotatably mounted in the pump with centered coupling without interference with a corresponding centering body (18, 11a). At least one of the two above-mentioned rotatable elements has a plurality of undercut regions (26, 34, 35) at the location of the centering walls. The undercut regions (26, 34, 35) comprise a wall portion which is spaced with respect to the facing wall of the respective centering body.
摘要:
Lid for a container for fluid coloring products, comprising a support element (12), substantially annular in shape and provided with an internal shoulder (16) on which the peripheral part of an impermeable and elastic membrane (22) rests, and a clamping element (23) disposed inside the support element (12) in order to keep the membrane (22) clamped against the internal shoulder (16). The support element (12) is provided in its upper part with an annular groove (29) and in its lower part comprises a corresponding annular protuberance (30) aligned with the annular groove (29).
摘要:
Device to deliver fluid products or suchlike, comprising a plurality of canisters (40), each one suitable to contain a predetermined fluid, and connected to an associated delivery unit (20). Each delivery unit (20) comprises a bellows pump (22), alternatively drivable between a condition in which it sucks in the fluid from the corresponding canister (40) and a condition in which it delivers the fluid. The delivery device also comprises actuator means able to cooperate directly or indirectly with each bellows pump (22) in order to drive it between the suction condition and the delivery condition. The actuator means comprise a acutation cam element (30), rotatable alternatively in two opposite directions of rotation, and having a profile able to cooperate during its rotation with the bellows pump (22), so as to define in a first direction of rotation the suction condition and in the opposite direction of rotation the delivery condition.
摘要:
A device and a method for preventing the drying of fluid products in a delivery head of a machine for dispensing fluid products, wherein the delivery head is provided with a plurality of delivery nozzles. The device comprises first elements to generate a conditioning flow, second elements to convey the conditioning flow towards a space underneath the delivery nozzles and create in said space an atmosphere different from that of the environment in which the dispensing machine is to be found during use. The delivery nozzles are divided into at least two groups and the space is divided into at least two distinct conditioning zones, disposed in correspondence with the groups of delivery nozzles. Different atmospheres are created in the conditioning zones, according to the type of fluid product delivered by the corresponding group of delivery nozzles.
