A control assembly for a material dispenser includes a plunger movably located within a bore of the assembly, the plunger having first and second ends, the first end having an abutment for moveably retaining the plunger within the bore and the second end for engaging a switch during operation of the material dispenser to cease operation. A biasing member located within the bore, the biasing member engaging the first end of the plunger, the biasing member allowing for the manual movement of the plunger without harm to the switch of the material dispenser during use.

The invention relates to a squeeze-out device for driving out a highly viscous dental material from a cartridge system, having an actuator, a motor, a controller, an operating device and at least one force sensor, wherein at least one discharging plunger of the cartridge system is drivable by the actuator, wherein the actuator is drivable by the motor or mechanically transmitted driving of the actuator is supportable by the motor, wherein the operating device is manually operable, wherein the at least one force sensor is connected to the operating device such that at least the magnitude of a force acting on the operating device and/or at least the magnitude of a torque acting on the operating device is measurable, and wherein the motor is controllable by the controller depending on the measured magnitude of the force acting on the operating device and/or of the torque acting on the operating device, said magnitude being measured by the at least one force sensor. The invention also relates to a method for driving at least one discharging plunger of a cartridge system by means of a squeeze-out device.

An electric glue gun includes a housing, a motor supported by the housing, a bracket which extends from the housing for supporting a glue cartridge, a pushing mechanism, supported by the housing and connected to the motor, comprising a drive rod wherein the pushing mechanism is driven by the motor to enable the drive rod to squeeze glue out of the glue cartridge, and a controller configured to control the motor to enable the drive rod to return by a preset distance after the motor stops driving the drive rod forward or after the drive rod reaches a limited position.

A caulking gun, comprising: a cylindrical housing; a nut fixed to a rear wall of said housing; a screw threaded into said nut, said screw having a bit at one end thereof, and a bearing connected to the other end thereof; a caulking tube situated inside said housing between a front wall thereof and said bearing, and a stopper, for preventing said bearing from reaching to said rear wall of said housing and as a result being separated from each other; wherein said bit having a depression, for allowing connecting thereto a snap connector, and wherein said housing comprises flexible straps, for providing compact storage of said caulking gun, and wherein said nut is further welded to a second wall of said housing, for holding said screw steady such that its longitudinal axis coincides with the longitudinal axis of said housing.

The present technology is a material dispensing system for controllably dispensing material from a packaging such as a chub pack. The system can include a housing capable of receiving the packaging, at least one nozzle tip including at least one piercing projection capable of piercing the packaging, a piston rod, a motor, and a transmission assembly for converting torque from the motor to a translation output of the piston rod. A ring gear can be operably associated with a planetary gear of the transmission, with a lock block slidingly engageable with the ring gear to prevent it from rotating or to allow the ring gear to rotate freely. A trigger is utilized to control the motor and to operate the lock block.

A method for dispensing fluid from a fluid dispensing apparatus. The apparatus may include a housing, wherein the housing may include a motor, and wherein the motor may be configured to be operatively connected to a power supply, wherein the motor may be further configured to be operatively connected to one or more drive rods, wherein the one or more drive rods may be configured to engage a fixed lead screw with a triangular nut, and wherein the drive rod may be further configured to engage at least two pistons of a fluid cartridge. The housing may include a controller configured to be operatively connected to the power supply, the controller may be configured to generate a pressure within the fluid cartridge by adjusting, via the motor, the drive rod and piston in a first direction relative to the fluid cartridge to dispense fluid in the fluid cartridge.

A dispensing apparatus having various features is described. The dispensing apparatus can receive a cartridge having a movable plunger configured to direct the fluid through a dispensing valve. The plunger can be movable under a force applied by air pressure. The cartridge can be inserted in the dispensing apparatus using a clamping and sealing mechanism and can be released using a cartridge ejector. The dispensing apparatus can include a ball valve having a ball defining an internal passageway that selectively aligns with a second internal passageway outside of the ball, a brush mounted via an elongating mechanism, and/or a gear train transmitting power from the elongating mechanism.
