Description

Technical Field

[0001] The utility model relates to the technical field of filling valve devices, and specifically relates to a filling valve with an anti-residue structure. Background Technique

[0002] The filling valve is a switch-type valve for accurately quantitatively controlling the flow rate, and is widely used in machinery such as food, packaging, petrochemical, metallurgy, painting, vehicles, and printing and dyeing. The characteristics of the valve are that the valve actuator adopts a light design, has a beautiful appearance, a compact structure, and excellent performance. It is famous for its fast filling speed, convenience, flexibility, accuracy and stability. As a relatively common switch-type valve in the liquid material packaging industry, the existing filling valves have different structures and cannot be universal. One filling valve cannot meet the requirements of different canned materials at the same time. Therefore, a large number of different types of filling valves have been derived. However, most filling valves mainly consider the filling object and rate, and often have residues of materials inside after filling, and the subsequent treatment is relatively troublesome.

[0003] For example, a filling valve with the publication number of CN101875479A includes a valve body with a liquid inlet channel. It is characterized in that a valve core seat is arranged in the valve body, and a filling channel communicated with the liquid inlet channel is arranged in the valve core seat; a sealing member is arranged on the lower end surface of the valve core seat, which can form a seal between the communication part of the filling channel and the workpiece filling port and the outside when they are communicated; a valve rod is axially arranged in the valve core seat, and an exhaust channel capable of communicating the inner cavity of the workpiece and the outside is arranged in the valve rod. One end of the valve rod is fixed with a valve core capable of blocking the filling channel and restricting the axial movement of the valve rod, and the other end of the valve rod passes through the valve core seat and is connected with a driving member.

[0004] The above device only includes parts such as a valve body, a valve core seat, a valve rod, and a driving member, and has the advantages of simple structure, reasonable design, and low production cost. Moreover, it does not require an external air source during use, has low usage conditions, and is convenient to operate. However, in the design, there is no structure for cleaning the internal residues. During the filling process, if the residues are cleaned or removed for a long time, it is easy for the internal residues to adhere to the inner surface, resulting in voids and the like in subsequent filling. Content of the Utility Model

[0005] The purpose of the utility model is to provide a filling valve with an anti-residue structure to solve the problems raised in the above background technique.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a filling valve with an anti-residue structure, comprising a filling shell, a connecting port is assembled at the upper end of the filling shell, and a connecting pipe is provided at the upper end of the filling shell, and a cleaning valve is assembled at the lower end of the connecting pipe, an inner concave layer is arranged in the middle section of the filling shell, and a connecting plate is installed on the outer side of the inner concave layer, and an embedded spring is assembled inside the inner concave layer, a filling port is assembled at the lower end of the filling valve, and a rubber bottom block is provided at the filling port, and a central pillar is inserted in the center of the filling shell.

[0007] Preferably, an embedded pipe nozzle is installed on the surface of the cleaning valve, and an engaging block is assembled inside the cleaning valve, and an engaging end is installed at a corresponding position of the engaging block.

[0008] Preferably, a connecting rod is installed at the rear side of the engagement end, and a straightening block is installed at the outer side of the connecting rod, and a stretching handle is installed at the rear end of the connecting rod.

[0009] Preferably, an embedded block is assembled on the outer side of the central pillar, and a fixed transverse plate is installed on the upper end of the embedded block, and the fixed transverse plate is embedded in the filling shell.

[0010] Preferably, a soft cushion attachment layer is provided on the inner surface of the filling shell, and the movable valve port is assembled inside the soft cushion attachment layer, and a positioning plate is installed at the lower end of the embedded block.

[0011] Preferably, a stop terminal is installed at the lower end of the movable valve port, and a bayonet terminal is inserted at the bottom of the central pillar.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. Compared with other filling valves, this device installs a movable valve port inside the filling valve, and uses the upper and lower structures to offset each other to form a sealing structure inside the device. The opening of the internal valve port requires the filling shell to move upward. It slides along the filling valve to scrape off the residues attached to the inner surface, avoiding the filling residues from adhering to the inner surface of the valve body.

[0014] 2. In addition, a cleaning valve is installed on the rear side of the device, which is installed on the material input structure. The internal front top block is inserted to maintain the open and closed state of the internal valve. This component, as an auxiliary structure of the filling valve, can flush the inside of the filling valve to avoid the presence of residues, and will not interfere with the operation of the main filling valve when this component is working. The two are independent of each other. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figures 1 to 3 , the utility model provides a technical solution:

[0021] Figure 1 This is a front overview of the device. The main body is a filling shell 1. The upper end of the filling shell 1 is equipped with a connection port for connecting the conveying end of the filling material. The upper end of the filling shell 1 is provided with a connecting pipe. At the same time, a cleaning valve 3 is installed at the lower end of the connecting pipe. The installation of the cleaning valve 3 allows the device to work relatively independently when cleaning the internal residues. It only needs to avoid the synchronization of the two. The middle section of the filling shell 1 is provided with a concave layer, and a connecting plate 6 is installed on the outer side of the concave layer for connecting and fixing the device. At the same time, an embedded spring 9 is installed inside the concave layer. The lower end of the filling valve is equipped with a filling port, and a rubber bottom block 5 is provided at the filling port. At the same time, a central pillar 13 is inserted in the center of the filling shell 1.

[0022] Figure 2 The cleaning valve 3 of the device is a structural diagram, wherein the main body is the cleaning valve 3, the embedded pipe port 2 is installed on the surface of the cleaning valve 3, and the inside of the cleaning valve 3 is equipped with an engaging block, and the engaging end 8 is installed at the corresponding position of the engaging block, and the connecting rod 7 is installed on the rear side of the engaging end 8, and the straightening block is installed on the outside of the connecting rod 7, and the stretching handle 4 is installed at the rear end of the connecting rod 7. The opening and closing of the internal valve port can be controlled by installing the stretching handle 4, so that the cleaning work inside can be controlled;

[0023] Figure 3This is the internal sectional view structure diagram of the device. The main body is the central pillar 13. The upper end of the central pillar 13 is designed with a slightly smaller radius, and the lower end is slightly larger. There is a gradually widened layer at the changing part. The outer side of the central pillar 13 is equipped with an embedded block 10. The embedded block 10 is assembled on the outer surface of the central pillar 13. The upper end of the embedded block 10 is provided with an embedded end, and there is an outer convex block 16 at the bottom. The installation of the outer convex block 16 realizes the internal closed structure. And a fixed cross plate 17 is installed at the upper end of the embedded block 10. The embedded block 10 is embedded in the interior of the fixed cross plate 17 to ensure the stability of the structure of the embedded block 10. At the same time, the fixed cross plate 17 is embedded in the filling shell 1. The inner surface of the filling shell 1 is provided with a soft pad attachment layer 11. And a movable valve port 12 is assembled inside the soft pad attachment layer 11. The movable valve port 12 is installed on the outer side of the embedded block 10, and there is a ramp surface inside at the middle position. The contact between the ramp surface and the outer convex block 16 generates a closed space to achieve the opening and closing effect of the overall filling valve port. At the same time, a clamping plate 15 is installed at the lower end of the embedded block 10, and a stop end is installed at the lower end of the movable valve port 12 to prevent the movement of the device from exceeding the limited position. The bottom of the central pillar 13 is inserted with a bayonet end 14 for fixing the storage bottle or tank used for filling.

[0024] During actual use, first, the device is mainly used for liquid materials with high adhesiveness. The upper connection port of the device is assembled on the conveying structure, and the embedded pipe orifice 2 on the surface of the cleaning valve 3 on the other side is connected to the cleaning structure. The stability effect is maintained by the connecting plates on both sides. As the material is filled and conveyed, with the filling bottle placed at the lower end, the device moves downward, and the bottle body presses against the bayonet end 14 to push the movable valve port 12 upward, causing a gap between the internal ramp surface and the outer convex block 16, allowing the filling material to be conveyed into the storage bottle. And during the filling process, due to the back-and-forth movement of the movable valve port 12, the residual material on the surface of the internal soft cushion layer is continuously scraped to prevent the residue from adhering to the inner surface of the filling shell 1. After the filling is completed, pull the stretching handle 4, use the cleaning valve 3 to flush the inside, and then take out the embedded block 10 for cleaning.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
