Description

Technical Field

[0001] This utility model relates to the field of filling valve assembly technology, specifically a filling valve assembly. Background Technology

[0002] A filling valve assembly is a core component of filling equipment responsible for the precise filling of liquids or pastes into containers. It typically consists of multiple filling valves and associated control and connection parts. By coordinating the opening and closing of these valves and combining pressure and flow control mechanisms, it achieves quantitative filling of containers of different sizes. It is widely used in production lines in the food and beverage, pharmaceutical, and chemical industries. Its design must balance filling speed, accuracy, and sealing. Some valve assemblies also have cleaning and anti-drip functions to adapt to different material characteristics (such as corrosiveness or foaming) and production requirements. It is a key system for ensuring filling efficiency and product quality.

[0003] The plunger head and drive mechanism of existing plunger filling valve assemblies are mostly connected in a complex manner. After long-term use, they may be damaged due to material wear and high-frequency extrusion. Disassembly and replacement require professional tools, which is not only time-consuming and labor-intensive, but also seriously slows down the production line maintenance progress and affects the continuity of production. At the same time, material can easily remain at the gaps between the filling tube and the components. Due to the fixed connection structure, it is difficult to clean thoroughly by conventional rinsing. In filling scenarios with extremely high hygiene requirements, such as food and pharmaceutical, residual material can easily breed microorganisms, thereby increasing the quality risk of product contamination and failing to meet the industry's strict standards for cleanliness and safety. Utility Model Content

[0004] The purpose of this utility model is to provide a filling valve assembly to solve the problems of inconvenient disassembly, maintenance and cleaning of existing plunger filling valve assemblies mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A filling valve assembly includes a filling tube, and an mounting assembly is disposed above the filling tube;

[0007] The mounting assembly includes a mounting tube, inside which is a plunger head. The top of the plunger head is provided with a threaded post. A sliding sleeve is slidably disposed on the outer side of the top of the filling tube, and a threaded sleeve is rotatably disposed above the sliding sleeve.

[0008] In a preferred embodiment of this utility model, a feed pipe is provided on one side of the filling tube, and a discharge pipe is provided at the bottom of the filling tube. Both the feed pipe and the discharge pipe are switched by a solenoid valve.

[0009] In a preferred embodiment of this utility model, the bottom outer side of the mounting tube is provided with an external thread, and the threaded sleeve is threadedly connected to the external thread.

[0010] In a preferred embodiment of this utility model, a sealing ring is provided at the bottom of the installation tube, the sealing ring is in contact with the top of the filling tube, the filling tube and the installation tube have the same inner diameter, and the plunger head is in contact with the inner wall of the filling tube and the installation tube.

[0011] In a preferred embodiment of this utility model, a cylinder is provided at the top of the mounting tube, and a threaded groove is provided on the telescopic end at the bottom of the cylinder, with the threaded column and the threaded groove being threadedly connected.

[0012] In a preferred embodiment of this utility model, a circular plate is provided on the outer side of the mounting tube, and a limiting rod is provided on the front side above the sliding sleeve, with the limiting rod being slidably connected to the front of the circular plate.

[0013] In a preferred embodiment of the present invention, a groove is provided behind the circular plate, an insert block is slidably disposed inside the groove, a slot is provided behind the top of the threaded sleeve, and the bottom of the insert block is installed and removed in the slot.

[0014] In a preferred embodiment of this utility model, a spring is provided at the top of the inner side of the slide groove, and a plug is connected to the bottom of the spring.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0016] Beneficial effects: When the plunger head wears out after prolonged use, a new plunger head can be prepared in advance for direct replacement, making it convenient to use. When connecting the filling tube to the installation tube, the sliding sleeve aligns the threaded sleeve with the external thread. By rotating the threaded sleeve to connect to the external thread, and simultaneously using the circular plate to limit the limit rod, the installation tube cannot rotate when the threaded sleeve is connected to the external thread, thus connecting the filling tube and the installation tube. A spring pushes the insert block into the slot, preventing the threaded sleeve from rotating. Conversely, when cleaning is required, simply reverse the threaded sleeve to separate the filling tube from the installation tube, facilitating cleaning of the inside of both tubes. The operation is very convenient.

[0017] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it according to the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] Please refer to Figures 1-4 This utility model discloses a filling valve assembly, which is a plunger-type filling device. It includes a filling pipe 1, which is the main mounting structure of the filling valve assembly and is used to install other structures. A feed pipe 11 is provided on one side of the filling pipe 1, and a discharge pipe 12 is provided at the bottom of the filling pipe 1. Both the feed pipe 11 and the discharge pipe 12 are switched by a solenoid valve, that is, the feed pipe 11 feeds the material and the discharge pipe 12 discharges the material.

[0026] An installation assembly is provided above the filling tube 1, which includes an installation tube 2. The filling tube 1 and the installation tube 2 have the same internal diameter. A plunger head 3 is provided inside the installation tube 2. The plunger head 3 contacts the inner wall of the filling tube 1 and the installation tube 2. The plunger head 3 is the material extrusion component. A threaded post 31 is provided at the top of the plunger head 3. A cylinder 32 is provided at the top of the installation tube 2. A threaded groove 33 is provided on the bottom telescopic end of the cylinder 32. The threaded post 31 and the threaded groove 33 are threadedly connected, that is, the threaded post 31 connects to the threaded groove 33, so that the plunger head 3 is installed on the bottom telescopic end of the cylinder 32. The thread is a fine thread. When the material enters the filling tube 1, the cylinder 32 pushes the plunger head 3 to quickly extrude the material. Conversely, when the plunger head 3 is worn after long-term use, a new plunger head 3 can be prepared in advance and directly removed for replacement, which is convenient to use.

[0027] A sliding sleeve 13 is slidably provided on the outer side of the top of the filling tube 1, and a threaded sleeve 14 is rotatably provided on the top of the sliding sleeve 13. An external thread 22 is provided on the outer side of the bottom of the installation tube 2. The threaded sleeve 14 is threadedly connected to the external thread 22. A circular plate 21 is provided on the outer side of the installation tube 2. A limit rod 23 is provided on the front side above the sliding sleeve 13. The limit rod 23 is slidably connected to the front of the circular plate 21. When the filling tube 1 is connected to the installation tube 2, the threaded sleeve 14 is made to engage with the external thread 22 by sliding the sliding sleeve 13. The threaded sleeve 14 is connected to the external thread 22 by rotating it. At the same time, the limit rod 23 is limited by the circular plate 21, so that the installation tube 2 cannot rotate when the threaded sleeve 14 is connected to the external thread 22. Thus, the filling tube 1 and the installation tube 2 can be connected. Conversely, when cleaning is required, the threaded sleeve 14 is reversed to separate the filling tube 1 and the installation tube 2, which facilitates cleaning of the inside of the filling tube 1 and the installation tube 2. The operation is very convenient.

[0028] A sealing ring 43 is provided at the bottom of the installation tube 2. The sealing ring 43 contacts the top of the filling tube 1. When the filling tube 1 and the installation tube 2 are connected, the sealing ring 43 contacts and compresses the top of the filling tube 1 to achieve a sealing effect. A slide groove 4 is provided behind the circular plate 21. An insert block 42 is slidably arranged inside the slide groove 4. A pull rod structure is provided at the top of the insert block 42 and extends to the top of the outer side of the slide groove 4, so that the insert block 42 can be pulled from the outside. A slot 24 is provided at the top rear of the threaded sleeve 14. The bottom of the insert block 42 is installed and removed in the slot 24. A spring 41 is provided at the top of the inner side of the slide groove 4. The spring 41 keeps pushing the insert block 42. The bottom of the spring 41 is connected to the insert block 42. When the filling tube 1 and the installation tube 2 are connected, the slot 24 aligns with the insert block 42. The spring 41 pushes the insert block 42 into the slot 24, so that the threaded sleeve 14 cannot rotate. Conversely, the threaded sleeve 14 can be rotated by pulling the insert block 42 from the top to remove it from the slot 24.

[0029] The working principle of this utility model is as follows: the threaded column 31 is connected to the threaded groove 33, so that the plunger head 3 is installed on the telescopic end of the bottom of the cylinder 32. When the material enters the filling tube 1, the cylinder 32 pushes the plunger head 3 to quickly squeeze out the material. Conversely, when the plunger head 3 is worn after long-term use, a new plunger head 3 can be prepared in advance and directly removed for replacement, which is convenient to use. When the filling tube 1 is connected to the installation tube 2, the threaded sleeve 14 is connected to the external thread 22 by sliding the sliding sleeve 13. The threaded sleeve 14 is connected to the external thread 22 by rotating it. At the same time, the circular plate 21 limits the limit rod 23, so that the installation tube 2 cannot rotate when the threaded sleeve 14 is connected to the external thread 22, thus connecting the filling tube 1 and the installation tube 2. The spring 41 pushes the insert block 42 into the slot 24, so that the threaded sleeve 14 cannot rotate. Conversely, when cleaning is required, the threaded sleeve 14 is reversed to separate the filling tube 1 and the installation tube 2, which facilitates cleaning of the inside of the filling tube 1 and the installation tube 2. The operation is very convenient.
