Definitions

• the invention relates to a system that prevents dripping in dosing, dispensing, and filling mechanisms used in various industries, by opening and closing the flow line near the tip of the nozzle.
• the invention is an anti-drip nozzle system that, through the movement of the piston, enables the plug to press against the seat ring, thereby closing the flow line and stopping the flow of the fluid from the nozzle. Conversely, when the plug is retracted, it opens the flow line, allowing the fluid to flow from the nozzle.
• the patent document CN102923630B discloses a drip prevention system where the movement of the piston enables the opening and closing of the nozzle.
• the movement of the piston is achieved by directing the fluid to be dispensed from the nozzle into the piston, where the force generated by the pressure of the fluid overcomes the force of the spring behind the piston, without the need for external control input.
• the movement of the piston is controlled by externally controlled compressed air.
• the mentioned patent document discloses the fluid inlet is on the side, without a mixing chamber in the system, and the direction of the fluid changes by 90 degrees after the inlet point. In present invention, the fluid coming from the mixing chamber moves along a straight flow line without changing its direction and exits from the nozzle tip. Additionally, the solution presented in the mentioned patent document does not discloses an anti- drip system with a long nozzle, which can be automated with an external control, suitable for serial dispensing and filling processes.
• the object of the invention is to enable the dispensing of the desired amount of fluid onto or into the workpiece during dispensing and filling processes, while preventing uncontrolled dripping of the fluid outside the targeted area on the workpiece or onto the production line before or after dispensing. This is achieved by opening and closing the flow line near the tip of the nozzle.
• Another object of the invention is to provide an anti-drip nozzle system that is suitable for serial production and automation.
• Figure 1 shows an external view of the anti-drip nozzle system.
• Figure 2 shows a cross-sectional view (E-E section) of the anti-drip nozzle system with the plug in the retracted position.
• Figure 3 shows a cross-sectional view (E-E section) of the anti-drip nozzle system with the plug in the extended position.
• Figure 4 shows a close-up cross-sectional view (E-E section) of the anti-drip nozzle system with the plug in the retracted position.
• Figure 5 shows a close-up cross-sectional view (E-E section) of the anti-drip nozzle system with the plug in the extended position.
• the invention relates to an anti-drip nozzle system (1) that provides the function of closing the flow line (20) passing through the plug slot (17.1) and stopping the material flow as a result of the plug (17) at the end of the piston (11) pressing the seat ring (19) with the movement of the piston (11). Conversely, opening the flow line (20) passing through the plug slot (17.1) and starting the material flow from the nozzle tip (15) as a result of the plug (17) at the end of the piston (11) being separated from the seat ring (19) by pulling back the piston (11).
• the anti-drip nozzle system (1) of the invention primarily comprises; at least one mixing chamber (10) that accommodates the fluid to be dispensed or filled, a piston (11) connected to said mixing chamber (10), at least one cylinder (13) surrounding the piston (11), at least one piston tube (12) connected to the piston (11), at least one compressed air inlet/outlet (13.1) in the said cylinder (13), at least one body tube (14) preferably connected to the said cylinder (13), followed by at least one nozzle tip adapter (16) preferably connected to the said body tube (14), followed by at least one nozzle tip (15) preferably connected to the nozzle tip adapter (16), and at least one plug (17) preferably connected to the end portion of the said piston tube (12).
• the mentioned mixing chamber (10) is preferably designed with a cylinder geometry and serves to supply the nozzle system with the fluid it contains.
• the nozzle system can be fed through a continuous or intermittent flow connection instead of the mixing chamber (10).
• the mentioned piston (11) is positioned inside the cylinder (13) to move forward and backward.
• the said piston tube (12) comprises at least one plug (17) preferably with cylindrical geometry, preferably connected to its end.
• the said plug (17), which has at least one plug slot (17.1) through which the fluid will flow, comprises at least one plug face (17.2), preferably having a flat or conical geometry, which closes the flow line (20) by pressing the seat ring (19).
• a gap (18) is formed between the plug (17) and the seat ring (19) by retracting the plug (17) so that the fluid coming from the plug slot (17.1) passes through the seat ring (19) and reaches the nozzle tip (15).
• the said seat ring (19), through which the fluid passes, is preferably made of a non-metallic material and preferably with a cylindrical geometry and is preferably placed on the nozzle tip (15).
• the body tube (14), preferably with a cylindrical geometry, is preferably connected to the cylinder (13) and is outside the piston tube (12) and extends to the nozzle tip adapter (16).
• the nozzle tip (15) can be directly connected to the body tube (14) instead of using the nozzle tip adapter (16).
• the fluid in the mixing chamber (10) passes through the flow line (20) formed by the piston tube (12), the plug slot (17.1), the gap (18), the seat ring (19) and the nozzle tip (15) respectively.
• the compressed air sent from the compressed air inlet/outlets (13.1) on the cylinder (13) enables the forward-backward movement of the piston (11) inside the cylinder (13).
• the plug (17) connected to the piston tube (12) separates from the seat ring (19) and opens the flow line (20).
• the fluid coming from the mixing chamber (10) passes through the flow line (20) formed by the gap (18) in the middle of the piston (11), the piston tube (12), the plug slot (17.1) on the plug (17), the gap (18) in the nozzle tip adapter (16), the seat ring (19) and the nozzle tip (15) and is dispensed into the desired location.
• the plug face (17.2) to close the flow line (20) by pressing the upper part of the nozzle tip (15) instead of the seat ring (19).
• the forward and backward movement of the piston (11) is preferably achieved through compressed air.
• it can also be accomplished using a hydraulic system or an electric motor.
• the opening and closing operation of the flow line (20) can be performed manually as well as by automation. This enables more efficient use of dispensed and filled materials and allows for serial production in dispensing and filling processes.
