Definitions

  • the present invention relates to a devi.ce for extruding chemical substances.
  • the present invention relates to a device for extruding chemical substances comprised inside tubes or cartridges inserted into the device and to distribute the substances on specific surfaces, the device being of the type comprising a piston and an adjustable handle.
  • the patent US 7,364,054 issued to HILTI AKTIENGESELLSCHAFT on April 29th, 2008 discloses a tool for dispending one or multi-component masses contained in cartridges or foil bags including at least one handle, at least one piston rod, a displacement mechanism for displacing the at .least one piston rod and having at least one displacement member and a locking member which are arranged on the at least one piston rod, are axially displaceable, and are pivotable in a longitudinal direction of the tool. It includes also a force transmission device acting on the displacement member and having a switching element arranged on the handle and able to be activated by an actuation member provided on the handle, and an actuator for actuation of the at least one displacement member and communicating with the switching element.
  • the described solution is affected by the problems that the velocity of the electric motor is not controlled and that the piston can't be released from the mechanism in a simple and rapid way.
  • Aim of the present invention is to provide a device for extruding chemical substances which is simply to manage and able to regulate the squeezing of the substances.
  • the extrusion device 20 comprises a container 1 having a circular cross-section open on one side for the insertion of a tube T containing the substance to he extruded.
  • the nozzle of the tube T can pass through an opening 1a.
  • the device 20 for extruding chemical substances can be used for extruding any kind of substance, changing the tube T.
  • the device 20 comprises also a housing 2, positioned at the opposite end of the opening 1a, comprising an electric motor having a piston 3 with a rack and some mechanical mechanism, such as gears, not shown in the figure.
  • the piston is provided with an abutment 11 having a ring for manually return back of the piston 3.
  • the housing 2 comprises an unlock button 10 functioning on manual pressure which allows the manually return back of the piston 3 releasing it from the mechanism of the device 20.
  • the housing 2 acts as stopping element for the piston 3.
  • a flat track 6 is placed in the inferior portion of the container 1 and is configured so that a handle 4 slides on it.
  • the flat track is provided with two abutments 7 and 7' acting as stopping elements and preventing the escape of the handle 4.
  • the handle 4 is provided, on the superior portion, with an indent 8 able to allocate an electronic card 5 and, on the inferior portion, of a box for allocating a battery 9. Moreover, some electric contacts let the electric current flows from the battery 9 to the electric motor passing through the electronic card 5.
  • the handle 4 is provided with a switch button 12 which is electrically connected to the electronic card 5 and is able to perform two different functions: - to regulate the output velocity of the substance of the tube T; - when it is released, to invert the direction of travel of the piston 3, so that the substance can't squeeze during the breaks and at the end of an extruding operation.
  • the handle can be adjusted based on the needs of the user.
  • the device for extruding chemical substances can be used by means of a single hand.
  • the electronic card 5 is able to execute three different functions: - to regulate the velocity of the electric motor; - to block the electric motor when the piston arrives to the end of its travel; - to automatically invert the piston direction when the button 12 is released.
  • the figure 4 shows the electric integrated circuit comprised inside the electronic card 5. It comprises an operational amplifier having four logic ports. A triangular wave is generated at the input of the logic ports in correspondence of the non inverting pad of the operational amplifier. Moreover, the circuit comprises a potentiometer H5 and two resistances R7, connected to a voltage signal VCC, and R4, connected to ground voltage signal, which are used to regulate the output signals F1 and F2. In addition, the circuit comprises a relay RL1 able to invert the rotation direction of the electric motor when the input signals end. The output signal of the integrated operational amplifier is used to charge the capacitor C1 and to activate the transistor T2. When the input signals end, the transistor T1 is activated sending a voltage signal to the coil of the relay RL1 which inverts the voltage output for a predetermined time period.
  • the electronic card controls the electric motor to activate the piston in adjustable way without user's effort.
  • the quantity and the velocity of chemical substances extruded can be regulated.
  • the piston can be controlled to invert its travel for a predetermined period, for example a short period, so that the chemical substances can't drip.
  • the device for extruding chemical substances can be managed in a more simply and user friendly manner.
  • Another advantage consists in the regulation the device can implement for controlling the velocity and the rotating direction of the motor, so that the movements of the piston can be controlled step by step.
  • the device according to the invention allows do not disperse some parts of chemical substances.
