A fast glue replenishment device by using a dispensing cartridge is illustrated, which has a power unit, a regulation unit, a gas container, a control unit and a dispensing cartridge. The regulation unit controls a gas pressure of a gas output by the power unit to be equal to a necessary gas pressure value which the dispensing cartridge pushes a supply material for dispensing. When the dispensing cartridge pushes the supply material for dispensing, the gas container continuously provides the gas having the gas pressure value into the dispensing cartridge by using the control unit, such that the dispensing cartridge is maintained to have the necessary gas pressure value which the dispensing cartridge pushes the supply material for dispensing. Thus, the supply material is pushed in a short path and in a time differential to increase accuracy of pushing the supply material for dispensing.

A reciprocating glue dispenser dispensing switch includes a switching device main body, a needle holding base, a sliding wear-resistant plate, and a driving device. The switching device main body is equipped with a double liquid inlet, the needle holding base is equipped with a mixed glue outlet, the sliding wear-resistant plate is installed between the switching device main body and the needle holding base, and the sliding wear-resistant plate is equipped with a sliding wear-resistant plate opening. The driving device is utilized to move the sliding wear-resistant plate. A mixed double-liquid glue passes through the double liquid inlet, the sliding wear-resistant plate opening and the glue outlet to dispense a mixed double-liquid glue while the double liquid inlet, the sliding wear-resistant plate opening and the glue outlet are overlapped. In addition, a double liquid dispensing equipment is also disclosed herein.

Provided are systems for dispensing a filament adhesive. The dispensing systems include a dispensing head with a barrel including one or more heating elements, and a rotatable screw received in the barrel, the rotatable screw including at least one mixing element. An inlet extends through a side of the barrel for receiving the filament adhesive. An outlet at a distal end of the barrel for dispensing the filament adhesive in molten form. The dispensing system further includes a filament adhesive having a configuration to be received into the inlet of the dispensing head. Using the provided dispensing systems, and optionally with the assistance of a computer, adhesives can be precisely applied to pre-determined locations on a substrate.

A dispensing system includes a dispensing unit assembly configured to dispense viscous material and a gantry coupled to the frame. The gantry is configured to support the dispensing unit assembly and to move the dispensing unit assembly in x-axis and y-axis directions. The dispensing unit assembly includes a support bracket secured to the gantry and a movable bracket rotatably coupled to the support bracket by a first strain wave gear system configured to enable the rotation of the movable bracket with respect to the support bracket about a first axis. The dispensing unit assembly further includes a dispensing unit rotatably coupled to the movable bracket by a second strain wave gear system configured to enable the rotation of the dispensing unit with respect to the movable bracket about a second axis generally perpendicular to the first axis.

An apparatus for conveying viscous material from a container having a base and an upwardly-extending shell includes: a follower plate movable towards and away from the base adjacent to the shell inner surface facing the interior and having an outlet and at least one deaeration and/or aeration opening; a deaerator for sucking air through the deaeration opening(s) and/or an aerator for introducing compressed air through the aeration opening(s); a lifting/lowering device for lifting/lowering the plate; a control for alternately controlling the lifting/lowering device in a movement mode and the deaerator or aerator in a deaeration or aeration mode, the lifting/lowering device having at least one vertical holding rod connected to a plate upper side, the plate being vertically movable in a limited manner relative to the rod; and a sensor for detecting and transmitting to the control upper and lower end plate positions relative to the rod.

A liquid material discharge device includes: a valve stem having a valve element provided at a tip portion, and a contact portion; a liquid chamber in which the valve element moves forward and backward; a nozzle communicating with the liquid chamber; a valve seat having a hole via which the liquid chamber and the nozzle communicate with each other; an arm that is in separable contact with the valve stem; and a valve driving device configured to move the valve element forward to and backward from the valve seat by causing the arm to pivot. The liquid material discharge device further includes a coupling device that couples the valve stem with the arm, wherein the coupling device includes a pressing portion that presses the contact portion against the arm.

Provided are dispensing devices and methods for a filament adhesive. The dispensing devices use a barrel including one or more heating elements, and a rotatable screw received in the barrel, the rotatable screw optionally including at least one mixing element. An inlet extends through a side of the barrel for receiving the filament adhesive, the inlet including a beveled nip point to prevent breakage of the filament adhesive as it is drawn into the barrel. An outlet at a distal end of the barrel for dispensing the filament adhesive in molten form. Using the provided dispensing devices, and optionally with the assistance of a computer, adhesives can be precisely applied to pre-determined locations on a substrate.

A fluid dispensing apparatus may be provided that includes a fluid reservoir configured to hold a liquid fluid. The fluid dispensing apparatus may include fluid output zones with at least one of the fluid output zones including plural fluid pumps. Each of the fluid pumps may have a flow rate at which the liquid fluid is pumped by the fluid pump. A slot die may also be provided that has a slot for each of the fluid output zones. The fluid dispensing apparatus may also include a relief valve mechanically connected to each of the fluid pumps, and a control device. The control device may be functionally connected to each relief valve, and the control device may be adapted to selectively instruct each valve to open or close to produce differing volume rates of fluid through each slot based on the relief valves selected.

An adhesive dispensing system for applying liquid adhesive to a substrate using different nozzles with the same manifold is disclosed. The adhesive dispensing system includes a manifold having a body, a first clamp configured to engage the body of the manifold, a second clamp configured to engage the body of the manifold, and a nozzle. The first and second clamps secure the nozzle to the body of the manifold. The body of the manifold has a first contact surface that engages the first clamp and a second contact surface that engages the second clamp and the nozzle, where the second contact surface is angularly offset from the first contact surface.

A device for applying a viscous material to workpieces includes a housing, an application channel extending in the housing up to an outlet opening, and a needle valve for opening and closing the application channel at a valve seat. An actuating element is mounted in the housing for rotation about a rotational axis extending parallel to a longitudinal direction in which the valve needle of the needle valve is movable relative to the housing. The actuating element has, in the radial lateral surface thereof, a guide groove extending circumferentially all around and curved in the axial direction in which at least one pin extending in the radial direction engages. The valve needle is connected to the actuating element or the at least one pin so that rotation of the actuating element about the rotational axis causes movement of the valve needle relative to the housing in the longitudinal direction.
