Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, specifically an intermittent double-valve sealed feeding device. Background Technology

[0002] Intermittent feeding devices refer to feeding equipment with a double-layer structure. The principle is that the material first enters the area between the upper and lower gates through the upper gate. Then, when the upper gate is closed, the lower gate is opened to discharge the material between the upper and lower gates. This can ensure the airtightness of the entire material conveying process. However, the main drawback of this type of structure is that the contact position between the gate and the feed inlet is not designed properly. Because the feed inlet diameter is too large, the gate size is large. The gate is in a flat state. When the gate is opened, too much material accumulates, which is not convenient for smooth discharge. In view of this, this application proposes an intermittent double-valve sealed feeding device.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-6This embodiment provides a technical solution: an intermittent double-valve sealed feeding device, comprising two feeding mechanisms stacked vertically, each feeding mechanism including a storage frame 1. A guide plate 5 inclined inwards towards the inside of the storage frame 1 is installed at the open end of the storage frame 1. An arc-shaped plate 6 is installed on one side of the inner wall of the storage frame 1. Two parallel inner sides of the storage frame 1 are fitted with side plates 7 connected to the guide plate 5 and the arc-shaped plate 6. A discharge port is enclosed between the guide plate 5, the arc-shaped plate 6, and the two side plates 7. A drive shaft 2 is rotatably mounted on the storage frame 1, and a cover covering the discharge port is connected to the drive shaft 2. Plate 4, wherein the power of the drive shaft 2 comes from the pneumatic push rod 12. Specifically, the pneumatic push rod 12 is hinged to the outside of the storage frame 1. The output rod of the pneumatic push rod 12 is hinged to the connecting rod 11. One end of the connecting rod 11 is connected to the drive shaft 2. When the output rod of the pneumatic push rod 12 extends, it drives the connecting rod 11 to move forward. At this time, the rotating connecting rod 11 will drive the drive shaft 2 to rotate, thereby driving the cover plate 4 to rotate. The cover plate 4 is not directly fixed to the drive shaft 2, but is connected to the drive shaft 2 through the mounting block 3. With the cooperation of the mounting block 3, the connection strength between the drive shaft 2 and the cover plate 4 is improved.

[0023] The technical feature of this application lies in the improvement of the structure of the open end, so as to... Figure 5 and Figure 6 Taking the perspective as an example, the cover plate 4 is in the closed state at this time, while the guide plate 5 is tilted towards the cover plate 4. During the material entry process, the material on the guide plate 5 moves closer to the cover plate 4, and the two side plates 7 have their opening ends reduced in diameter. In this way, the size of the cover plate 4 inside the storage frame 1 can be reduced accordingly, avoiding direct contact and friction between the cover plate 4 and the inner wall of the storage frame 1. The arc plate 6 is designed to avoid the opening being too small and causing material blockage due to the use of the guide plate 5. Because of the presence of the arc plate 6, the cover plate 4 does not need to contact the inner wall of the storage frame 1 at one end. Moreover, the arc plate 6 has a small structure design, and the material entering the arc plate 6 slides directly off the surface of the arc plate 6, thus preventing material accumulation. In addition, in this application, the cover plate 4 is in an inclined state when closed, while most existing designs use a flat state. In this way, when the cover plate 4 is rotated open, the material that is in an inclined state will be discharged smoothly, which is beneficial for material discharge.

[0024] In summary, the feeding device proposed in this application improves the structure of the inlet, causing the material to be discharged to accumulate downwards. This facilitates the smooth discharge of the material when the cover plate 4 is opened. Moreover, the design of the arc plate 6 does not result in an excessively small discharge port diameter and does not cause material residue. The structural design is reasonable and more practical.

[0025] In a preferred embodiment, a first sealing strip 8 is installed on the rear side of the guide plate 5, which is in close contact with the cover plate 4, and a second sealing strip 10 is installed on the inner side of the arc plate 6, which is in close contact with the cover plate 4. The purpose of the first sealing strip 8 and the second sealing strip 10 is to improve the sealing performance at the contact position. A support rod 9 is connected between the arc plate 6 and the inner wall of the storage frame 1.

[0026] In a preferred embodiment, a baffle 13 inclined toward the discharge port is installed inside the storage frame 1. The baffle 13 is there to guide the material being discharged. As the cover plate 4 gradually opens, it will come into contact with the baffle 13, thus forming a stable discharge channel inside the upper storage frame 1, which helps the material to be discharged into the lower storage frame 1.

[0027] In a preferred embodiment, a top rod 14 and a spring telescopic rod 15 are hinged to the cover plate 13. One end of the spring telescopic rod 15 is hinged to the top rod 14, and a roller 16 is installed at the end of the top rod 14. When the cover plate 4 is opened, the material it carries increases the load on the cover plate 4. To improve the support effect, when the cover plate 4 is opened and rotated, the cover plate 4 will contact the roller 16 at the end of the top rod 14. At this time, the roller 16 will roll on the surface of the cover plate 4, the top rod 14 will rotate and drive the spring telescopic rod 15 to rotate and retract, thereby forming a support function, providing a certain support for the cover plate 4, and improving the stability of the cover plate 4 when discharging material. When the cover plate 4 is reset, the spring telescopic rod 15 also drives the top rod 14 and the roller 16 to reset.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
