Description

Technical Field

[0001] This utility model belongs to the field of filling machine technology, and in particular relates to a filling head for a fully automatic filling machine with anti-drip function. Background Technology

[0002] In modern industrial production, filling machines, as key equipment for automated liquid filling, are widely used in food, pharmaceutical, chemical, and daily chemical industries. The filling gun, as the core component of the filling machine, directly affects the filling accuracy, efficiency, and material waste. During the filling process, after filling is complete, a small amount of liquid often remains inside the filling gun, and leakage may occur at the nozzle outlet due to poor sealing.

[0003] Leakage not only wastes materials and increases production costs, but can also contaminate packaging containers and the production environment, affecting product quality and production safety. Therefore, effectively solving the leakage problem of filling guns is a crucial issue that urgently needs to be addressed in the design and manufacturing of filling machines.

[0004] Currently, filling guns on the market typically employ sealing measures to prevent dripping, such as sealing valves or caps at the nozzle outlet. However, these sealing measures often have limitations. On the one hand, traditional sealing structures are susceptible to corrosion and wear from liquid materials during long-term use, leading to decreased sealing performance and subsequent dripping. On the other hand, relying solely on the outlet seal cannot completely solve the problem of residual liquid inside the filling gun; this residual liquid may still drip from the outlet under gravity.

[0005] To address these issues, we provide a fully automatic filling head with anti-drip function to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this invention is to provide a filling head for a fully automatic filling machine with anti-drip function. By combining the sealing component and the adsorption component, the problem of poor anti-drip performance of filling guns in the prior art is solved.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0008] This utility model relates to a filling head for a fully automatic filling machine with anti-drip function. It includes an electric push rod, a sealing assembly fixedly connected to the bottom of the electric push rod, a second electric push rod fixedly connected to the top of the inner cavity of the sealing assembly, a filling gun fixedly connected to the bottom of the second electric push rod, and an adsorption assembly fixedly connected to one side of the filling gun. The sealing assembly includes a sealing sleeve fixedly connected to the electric push rod, a sliding groove at the bottom of the sealing sleeve, sealing plates slidably connected to both sides of the inner cavity of the sliding groove, a sliding rod fixedly connected to the inner cavity of the sealing plate, the other end of the sliding rod extending to the outside of the sealing sleeve, and a spring sleeved on the surface of the sliding rod. The two ends of the spring are fixedly connected to the sealing sleeve and the sealing plate, respectively. The adsorption assembly includes an installation groove at the bottom of the surface of the filling gun, an adsorption tube fixedly connected to the inner cavity of the installation groove, and a flexible hose connected to the other end of the adsorption tube. The other end of the flexible hose extends to the outside of the sealing sleeve and is connected to an external suction pump.

[0009] The present invention is further configured such that an electromagnetic valve is fixedly connected to the inner cavity of the filling gun, and a second flexible hose is connected to the top of one side of the filling gun. The other end of the second flexible hose extends through to the outside of the sealing sleeve and is connected to the delivery pump of the filling machine. The electromagnetic valve enables precise control of the filling process, and the connection between the second flexible hose and the delivery pump ensures the stability and accuracy of liquid delivery.

[0010] The present invention is further configured such that a sealing groove is provided on the inner cavity of the sliding groove and on the left and right sides of the front and back sides of the sealing plate. A sealing strip is bonded to the inner cavity of the sealing groove by an adhesive. The design of the sealing groove and the sealing strip enhances the sealing between the sliding groove and the sealing plate and prevents liquid from seeping out from the side.

[0011] The present invention is further configured such that a conical groove is provided on the top of the sealing plate, and a sealing groove is provided on the opposite side of the two sealing plates. A sealing strip is bonded to the inner cavity of the sealing groove by an adhesive. The conical groove facilitates the filling gun to squeeze the two sealing plates, making them relatively far apart. The sealing groove and the sealing strip further enhance the sealing performance when the sealing plates are closed.

[0012] The present invention is further configured such that sliding holes are provided at the bottom of both sides of the sealing sleeve, and the end of the sliding rod away from the sealing plate extends into the inner cavity of the sliding hole. The design of the sliding hole provides precise guidance for the sliding rod, ensuring smooth sliding of the sealing plate and avoiding jamming.

[0013] The present invention is further configured such that the sealing plate is in the shape of an inverted U-shape, and openings are provided on both sides of the sealing sleeve for sliding of the sealing plate. The design of the inverted U-shape sealing plate and the openings not only ensures the sealing effect, but also provides sufficient space for the sliding of the sealing plate.

[0014] The present invention is further configured such that the number of sliding rods and springs is six, and three are arranged in a group, and they are installed on the inner wall of the sealing plate at equal intervals. The symmetrical distribution of multiple groups of sliding rods and springs ensures that the sealing plate is subjected to uniform force, thus ensuring synchronicity and sealing when closing.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model achieves a dual anti-drip function by setting a spring-driven sealing plate structure at the bottom of the filling gun and cooperating with an internal liquid suction device. After filling is completed, the electric push rod two drives the filling gun to return to its original position, and the sealing plate automatically closes under the action of the spring, forming the first line of defense. At the same time, the adsorption component is connected to an external suction pump through a hose one to promptly remove residual liquid in the inner cavity of the filling gun, forming the second line of defense. This dual protection mechanism effectively solves the dripping problem caused by wear of traditional sealing structures, and greatly improves the cleanliness and stability of the filling process.

[0017] 2. This utility model adopts a modular design concept, which organically combines the electric push rod one, sealing component, electric push rod two, filling gun and adsorption component. Each component is connected by bolts or welding, which is convenient for disassembly and replacement. This design reduces equipment maintenance costs, shortens downtime, and improves production efficiency. It is especially suitable for industries with strict hygiene requirements such as food and medicine. Attached Figure Description
