Description

Technical Field

[0001] The utility model relates to the technical field of packaging, and more specifically, to a quantitative packaging device for hexagonal boron nitride powder. Background Art

[0002] Hexagonal boron nitride (h-BN) is a white powder material. Its crystal structure is very similar to that of graphite, and the physical and chemical properties of the two are also similar. Therefore, hexagonal boron nitride is also called "white graphite". It has important applications in thermal conductivity, lubrication, hydrogen storage, battery diaphragm materials, high-temperature antioxidant coatings, catalysis and other fields. Packaging devices are required in the production process of hexagonal boron nitride.

[0003] For example, the related patent retrieved: CN219524306U discloses a quantitative packaging device for hexagonal boron nitride powder. The prior art uses a motor, a second connecting rod, a cam, a first groove, a damping spring shock absorber, a funnel, a first electric telescopic push rod, a baffle and an expander. The expander can be controlled by the first electric telescopic push rod to push into the packaging bag, and at the same time, the packaging bag is supported to prevent the product from being pressed at the bag opening when being installed, thereby affecting the subsequent work process and increasing the labor of the staff.

[0004] However, the inventors found that the prior art has the following problems during implementation: when the prior art is in use, the baffle is pushed so that the baffle does not block the bottom of the funnel, and the hexagonal boron nitride powder in the funnel can fall into the expander. However, the funnel and the expander in the prior art have a certain height difference. At the same time, the existing hexagonal boron nitride is generally in powder form and has a relatively light weight. As a result, the hexagonal boron nitride powder is easily affected by the surrounding airflow and scatters during the process of falling from the funnel to the expander, resulting in partial loss of the hexagonal boron nitride powder during the feeding process, which affects the accuracy of the hexagonal boron nitride powder packaging. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide a hexagonal boron nitride powder quantitative packaging device which reduces the loss of hexagonal boron nitride powder during packaging.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] The utility model is further configured as follows: a baffle is provided at the bottom of the funnel, the upper surface of the baffle is in contact with the lower surface of the funnel, and the baffle can seal the bottom of the funnel.

[0023] Specifically, it refers to a quantitative packaging device for hexagonal boron nitride powder, including a bottom plate 1, an n-type frame 2 is fixedly installed on the upper surface of the bottom plate 1, a funnel 3 is fixedly installed on the horizontal plate of the n-type frame 2, the bottom of the funnel 3 penetrates the lower surface of the horizontal plate of the n-type frame 2, a baffle 4 is provided at the bottom of the funnel 3, the upper surface of the baffle 4 contacts the lower surface of the funnel 3, so that the bottom of the funnel 3 can be sealed to avoid the leakage of the hexagonal boron nitride powder in the funnel 3, and a rear plate 5 is fixedly installed on the rear side surface of the n-type frame 2. A first cylinder 6 is fixedly installed on the back of the rear plate 5. One end of the telescopic rod of the first cylinder 6 slides through the rear plate 5 and is fixedly connected to the baffle 4. When feeding, the first cylinder 6 is started, and the telescopic rod of the first cylinder 6 drives the rear plate 5 to move backward, so that the rear plate 5 does not block the bottom of the funnel 3, so the hexagonal boron nitride powder in the funnel 3 falls. In this way, it is only necessary to set the time difference when the first cylinder 6 is extended and retracted to control the falling amount of the hexagonal boron nitride powder in the funnel 3, thereby achieving the purpose of quantitative packaging.

[0024] An expander 7 is provided in the n-type frame 2, and the expander 7 and the funnel 3 are in the same vertical position. Slide grooves 9 are provided on the opposite surfaces of the two vertical plates of the n-type frame 2. First support plates 8 are fixedly connected to the opposite two side surfaces of the expander 7. The other side of the first support plate 8 extends into the slide groove 9 and slides in the slide groove 9. A second cylinder 10 is fixedly installed at the bottom of the slide groove 9. The upper end of the telescopic rod of the second cylinder 10 is fixedly connected to the lower surface of the first support plate 8. When in use, the second cylinder 10 is started, and the telescopic rod of the second cylinder 10 drives the expander 7 to move downward, so that the expander 7 can be inserted into the packaging bag, and at the same time, the packaging bag can be supported to prevent the hexagonal boron nitride powder from being poured into the packaging bag and pressed at the bag mouth.

[0025] A sealed through pipe 11 is provided between the expander 7 and the funnel 3. Second support plates 15 are fixedly installed on the opposite two side surfaces of the sealed through pipe 11. The other side of the second support plate 15 is fixedly connected to the vertical plate of the n-shaped frame 2. A second movable pipe 13 and a first movable pipe 12 are respectively provided on the upper and lower sides of the sealed through pipe 11. The lower side of the first movable pipe 12 is fixedly installed on the upper surface of the expander 7. Two movable grooves 14 are provided on the upper and lower side surfaces of the sealed through pipe 11. One side of the first movable pipe 12 adjacent to the second movable pipe 13 extends into the two movable grooves 14 respectively. When the baffle 4 no longer seals the bottom of the funnel 3, the second movable tube 13 can be controlled to move upward and wrap the bottom of the funnel 3. At this time, when the hexagonal boron nitride powder in the funnel 3 falls, it can be transported in the second movable tube 13, the sealed through tube 11 and the first movable tube 12, which avoids the situation that the hexagonal boron nitride powder is blown by the airflow due to the lack of obstacles when falling vertically, further ensures the accuracy of the hexagonal boron nitride powder packaging, and reduces the loss of the hexagonal boron nitride powder during packaging.

[0026] Adjustment plates 16 are fixedly installed on the opposite two side surfaces of the second movable tube 13, and push plates 17 are fixedly installed on the opposite two side surfaces of the baffle 4. A rotating shaft 18 is rotatably connected to the inner side surface of the vertical plate of the n-shaped frame 2, and a rotating plate 19 is fixedly sleeved on the rotating shaft 18. The upper surface of the lower side of the rotating plate 19 contacts the adjustment plate 16, and the upper side of the rotating plate 19 contacts the push plate 17. When the baffle 4 moves to the rear side, the push plate 17 will move synchronously with the baffle 4. When the baffle 4 moves to a certain distance, the push plate 17 will contact the upper side of the rotating plate 19 and form a thrust on the rotating plate 19, so that The rotating plate 19 rotates clockwise with the rotating shaft 18 as the rotating point, and the lower side of the rotating plate 19 synchronously pushes the adjusting plate 16 to move upward, and the adjusting plate 16 drives the second movable tube 13 to move upward. When the baffle 4 does not block the bottom of the funnel 3 at all, the pushing plate 17 pushes the rotating plate 19 to be horizontal, and the adjusting plate 16 moves to the highest point at the same time, and the second movable tube 13 can wrap the bottom of the funnel 3. The above-mentioned simple mechanical linkage structure can control the second movable tube 13 to move synchronously with the baffle 4, without the need for secondary control by human or electric components, and has high stability and accuracy.

[0027] The working principle of the quantitative packaging device for hexagonal boron nitride powder provided by the utility model is as follows: the first cylinder 6 is started, and the telescopic rod of the first cylinder 6 drives the rear plate 5 to move backward. When the baffle plate 4 moves to a certain distance, the push plate 17 will contact the upper side of the rotating plate 19 and form a thrust on the rotating plate 19, so that the rotating plate 19 rotates clockwise with the rotating shaft 18 as the rotating point, and the lower side of the rotating plate 19 simultaneously pushes the adjusting plate 16 to move upward, and the adjusting plate 16 drives the second movable tube 13 to move upward. When the baffle plate 4 does not block the bottom of the funnel 3 at all, the push plate 17 pushes the rotating plate 19 to be horizontal, and the adjusting plate 16 moves to the highest point, and the second movable tube 13 can wrap the bottom of the funnel 3.
