Description

Technical Field

[0001] This utility model relates to the field of filling technology, and in particular to an improved structure of a filling machine. Background Technology

[0002] Existing filling machines output material from a pipeline according to a set quantity, and then close the outlet through a valve to control the output quantity. However, existing valves only close the outlet. Since the materials being filled are diverse, some may contain solid particles, such as nuts mixed in with syrup. During spraying, the nozzle is easily blocked by these solids, leading to poor subsequent material discharge. To address this, the applicant has developed the technology described in patent application 202411447197.3. This technology includes a material conveying pipeline, a valve installed on the pipeline and perpendicular to it, and a valve seat with a shaft hole perpendicular to the pipeline located at the upper part of the horizontally positioned pipeline, a valve core that moves up and down along the shaft hole driven by a power source mounted on the valve seat, and a valve port located at the lower part of the pipeline, directly facing the valve core. The valve port is tubular in shape, and a sealing structure is provided between the valve core and the shaft hole. The end of the valve core is a columnar object that matches the tubular valve port. Driven by the power source, the valve core can penetrate into or move away from the valve port.

[0003] During use, materials are conveyed to the conveying pipeline at a certain conveying pressure. When filling is required, the power drives the valve core upward, and the columnar object at the lower end of the valve core leaves the valve port, allowing the material to spray out from the valve port, completing the filling operation. Then, the power drives the valve core downward, and the columnar object at the lower end of the valve core inserts into the valve port. At the same time as insertion, it carries out the material stuck in the valve port. Since the end of the valve core is a columnar object that matches the orifice-shaped valve port, even if there is material (such as nuts in syrup) stuck in the valve port, it will be cleared out of the valve port by the action of the columnar object. When the valve is opened, the columnar object is suspended in the conveying pipeline, and there are no obstacles around the columnar object. When the valve is opened, the material in the conveying pipeline flows smoothly to the valve port, ensuring smooth material spraying.

[0004] While this technology can theoretically prevent nozzle blockage and ensure smooth material ejection, the cylindrical valve opening presents a challenge. If solid material remains between the valve opening and the end of the cylindrical valve core, the end of the valve core can easily become stuck. Furthermore, the material trapped between the valve opening and the end of the cylindrical valve core can be squeezed tightly against the valve opening, making it difficult to remove and preventing the end of the cylindrical valve core from smoothly inserting into the valve opening. Summary of the Invention

[0005] The purpose of this invention is to provide an improved structure for a filling machine that overcomes one or more of the above-mentioned disadvantages, prevents nozzle blockage, prevents solid matter from accumulating between the orifice-shaped valve opening and the end of the columnar valve core, and ensures smooth material ejection.

[0006] This utility model filling machine is implemented as follows: it includes a material conveying pipe with a material inlet, a valve installed on the conveying pipe and perpendicular to the conveying pipe, the material inlet axis being perpendicular to the conveying pipe axis, the valve including a valve seat with a shaft hole perpendicular to the conveying pipe installed at the upper part of the horizontally installed conveying pipe, a valve core driven by a power source installed on the valve seat to move up and down along the shaft hole, and a valve port installed at the lower part of the conveying pipe, the valve port facing the valve core, the valve port being pipe-shaped, the port of the valve port located in the inner cavity of the conveying pipe being trumpet-shaped, a sealing structure being provided between the valve core and the shaft hole, the end of the valve core being a columnar object matching the pipe-shaped valve port, the valve core being driven by a power source to penetrate into or move away from the valve port, its special feature being that the valve port is a tapered hole with a large upper opening and a small lower opening, the taper of the tapered hole being 1-10 degrees.

[0007] During use, materials are conveyed to the conveying pipeline at a certain conveying pressure. When filling is required, the power drives the valve core to move upward, and the columnar object at the lower end of the valve core leaves the valve port, allowing the material to spray out from the valve port, completing the filling operation. Then, the power drives the valve core to move downward, and the columnar object at the lower end of the valve core inserts into the valve port. At the same time as insertion, it carries out the material stuck in the valve port. Since the end of the valve core is a columnar object that matches the orifice-shaped valve port, even if there is material (such as nuts in syrup) stuck in the valve port, it will be cleared out of the valve port by the action of the columnar object. When the valve is opened, the columnar object is suspended in the conveying pipeline, and there are no obstacles around the columnar object. When the valve is opened, the material in the conveying pipeline flows smoothly to the valve port, ensuring smooth material spraying.

[0008] The valve port adopts a conical hole. When the end of the columnar valve core is inserted into the valve port, the fluid pressure caused by the instantaneous narrowing of the valve port causes the fluid to carry the solid away from the valve port. The presence of the conical hole makes it less likely for the solid next to the end of the columnar valve core to be stuck between the conical hole and the end of the columnar valve core, thereby avoiding the solid from being stuck between the pipe-shaped valve port and the end of the columnar valve core.

[0009] Compared with existing technologies, this invention has the advantages of preventing the nozzle from becoming blocked and preventing solids from remaining between the orifice-shaped valve opening and the end of the columnar valve core, thus ensuring smooth material ejection.
