摘要: The invention relates to a filtering device for filtering a fluid, and in particular a liquefied plastic. The filtering device includes a control unit to control the position of a screen carrier by generating control signals such that the fluid pressure in a fluid inlet channel and/or in a fluid outlet channel remains within definable pressure ranges while a cavity is being filled.

摘要: Systems and methods for venting a solvent are disclosed. The system includes a chamber, such as an oven having an interior volume defining a heating zone, where the interior volume receives at least one substrate coated with a coating material comprising a solvent. The system further includes a vent coupled to the oven and defining a passage between the interior volume and the environment external to the oven. The system also includes a solvent sensor measuring an amount of evaporated solvent present in the interior volume, and a fan removing at least a portion of the solvent from the interior volume. The system may also include a coating assembly including an applicator and a flow meter, wherein the applicator applies a portion of the coating material to the substrate, and the flow meter determines the amount of coating material applied to the substrate.

摘要: A dense phase pump has two housings that are attached together using a single releasable fastener. The fastener can be released to allow the two housings to be separated thereby providing access to replaceable components. The replaceable components may include one or more pinch valves or one or more barrier elements. A pinch valve for a dense phase pump has a shape or profile for aligning the pinch valve when the pinch valve is installed in a pinch valve body. The pinch valve optionally has two end flanges, with each end flange having a shaped periphery. The two end flanges may have the same size and shape so that the pinch valve can be installed in either of two orientations that are inverse. A dense phase pump has a pump chamber that can be purged by purge gas that enters the pump off-axis from a purge path axis.

摘要: Systems and methods for direct heater diagnostics for a hot melt liquid dispensing system are disclosed. At least one of a current measurement or a voltage measurement is received from a respective current and/or voltage sensor positioned at an electrical circuit that supplies electric power to a heater associated with the dispensing system. The heater can be for an applicator or heated hose attached to the dispensing system, a melter of the dispensing system, or a pump of the dispensing system. A state of the electrical circuit is determined based on the at least one of the current or voltage measurement.

摘要: Systems and methods for air pressure control in a hot melt liquid dispensing system are described. An example hot melt liquid dispensing system includes a pump that pumps hot melt liquid to an applicator. The hot melt liquid dispensing system also includes an air flow path that supplies pressurized air to the pump and an electronic pressure sensor associated with the air flow path. The hot melt liquid dispensing system also includes a controller that receives an electronic signal from the electronic pressure sensor indicative of an air pressure in the air flow path and causes adjustment to the air pressure in the air flow path based on the electronic signal from the electronic pressure sensor.

摘要: Systems and methods of a container having a tack welded fin seal. The container may include a film, a tack weld joining a first outer portion of a first edge and a second outer portion of the first edge, and a fin seal joining a first inner portion of the first edge of the film and a second inner portion of a second edge of the film. The container may include a faceplate integrally molded to an outer layer of a first end portion of the film. The faceplate may include substantially the same composition as an outer layer of the first end portion, such that no distinct layers are formed between the faceplate and the film. The tack weld may be formed at a tack welding system, and the fin seal may be formed at a fin sealing system having a mandrel.

摘要: A nozzle assembly includes a first body having an upper and an inner surface; a first channel in the first body to receive a material; a second body having an upper and an inner surface; a second channel in the second body, in liquid communication with the first channel, and configured to receive the material from the first channel; a material outlet defined by the first and second bodies configured to discharge the material; a material inlet on the upper surface of the first body, in liquid communication with the first channel, and configured to receive the material into the nozzle assembly; and an upper lip extending from the first body toward the second body and partly defined by the upper surface of the first body. The upper lip includes a lip surface opposite the upper surface of the first body. The upper surface of the second body is configured to contact the lip surface of the upper lip.

摘要: Systems and methods for dispensing a liquid onto a substrate are disclosed. A dispensing assembly includes a housing, a valve stem, and a control valve. The housing receives the liquid to be dispensed. The valve stem is disposed in the housing and has a first configuration, in which the liquid is allowed to exit the housing, and a second configuration, in which the liquid is prevented from exiting the housing. The control valve receives pressurized air from a pressurized air source. The control valve has a first position, in which the pressurized air acts on the valve stem to move the valve stem to the first configuration or to the second configuration, and a second position, in which the pressurized air is moved out of the dispensing assembly through an exhaust passage defined therein.

摘要: A dispensing system for jetting a material onto a substrate is disclosed. The dispensing system includes a plate defining a first surface, a second surface opposite the first surface in a first direction, and at least one slot that extends through the plate from the first surface to the second surface, and an actuator assembly that contains a piezoelectric element and is operatively coupled to the needle. The dispensing system also includes at least one fastener that extends through the actuator assembly and the at least one slot, where the at least one fastener is configured to selectively engage the plate such that 1) in a disengaged configuration, the at least one fastener is movable within the slot and the actuator assembly is movable relative to the plate, and 2) in an engaged configuration, the at least one fastener is not movable within the slot and the actuator assembly is not movable relative to the plate such that a stroke length of the needle is adjusted.
