The metering box is set below the silo to receive the material flowing out of the lower discharge port of the silo. A scraper is set above the metering box to scrape the material on the top of the metering box. A knife plate is set above and below the metering box to block the bottom opening of the metering box when receiving the material and to lower the material when it is full. The existing metering filling device has the following shortcomings:

[0003] 1) The knife plate uses horizontal reciprocating motion to discharge the material from the bottom of the metering box. The knife plate is a hard structure. During the discharge process, the material on the knife plate moves to one side of the metering trough along with the knife plate. The contact area between the side wall of the metering trough and the knife plate exerts a large rigid squeezing force on the material, which is easy to damage the material;

[0004] 2) The material on the top of the metering box is scraped flat by the horizontal reciprocating movement of the scraper, which is easy to damage the material;

[0005] 3) The materials scraped off by the scraper are not easy to collect;

[0006] 4) The materials in the silo fall directly onto the metering box, which is easy to form accumulation on the metering box. The extrusion force between the materials is large, and the shear force between the materials is large when the scraper scrapes the materials, which is easy to damage the materials;

[0007] 5) The capacity of the metering box is fixed, which makes it difficult to meet the requirements of different filling volume specifications. Utility Model Content

[0041] Embodiment 1:

[0042] Figures 1 to 8 An embodiment of the material blocking and blanking mechanism of the utility model is shown. The material blocking and blanking mechanism of this embodiment includes a material storage part 3 and a material blocking and blanking assembly 5. The material blocking and blanking assembly 5 includes a material blocking belt 52. The material blocking belt 52 is movably arranged below the material storage part 3. The opening and closing of the blanking port at the bottom of the material storage part 3 is realized by the movement of the material blocking belt 52.

[0043] This material blocking and dropping mechanism uses the movement of the material blocking belt 52 to realize the opening and closing of the dropping port at the bottom of the material storage component 3, thereby realizing material discharge and blocking. Since the material blocking belt 52 is made of flexible material, the material and the material blocking belt 52 are flexibly connected. There will be no rigid squeezing force on the material in the contact area between the inner wall of the material storage component 3 and the material blocking belt 52, thereby avoiding damage to the material.

[0044] Furthermore, if Figure 2 and Figure 3 As shown, in this embodiment, the material blocking and blanking assembly 5 further includes a moving seat 51 and a moving driving assembly, the moving driving assembly is connected to the moving seat 51, and is used to drive the moving seat 51 to move back and forth, and the material blocking belt 52 is arranged on the moving seat 51. The moving driving assembly drives the moving seat 51 to move back and forth, and the moving seat 51 drives the material blocking belt 52 to move, so as to realize the opening and closing of the blanking opening at the bottom of the material storage component 3. When the blanking opening at the bottom is opened, the belt located below the material storage component 3 moves downward under the drive of the moving seat 51, and does not interact with the inner side wall of the material storage component 3, and the material storage component 3 and the belt do not generate shear force on the material.

[0045] Furthermore, in the present embodiment, the mobile driving assembly comprises a first pulley 53, a second pulley 54, a third pulley 55 and a mobile driving member 56, the mobile seat 51 is arranged below the material storage member 3, the first pulley 53 and the second pulley 54 are arranged on the mobile seat 51, the third pulley 55 is fixedly arranged, the mobile driving member 56 is connected to the mobile seat 51, and the material blocking belt 52 is sequentially wound around the first pulley 53, the second pulley 54 and the third pulley 55; the first pulley 53 and the third pulley 55 both abut against the inner side of the material blocking belt 52, and the second pulley 54 abuts against the outer side of the material blocking belt 52.

[0046] The moving driving member 56 drives the moving seat 51 to move back and forth, and the moving seat 51 drives the first belt pulley 53 and the second belt pulley 54 to move synchronously, thereby driving the material blocking belt 52 to move, so as to realize the opening and closing of the bottom material drop opening of the material storage component 3. Figure 3 As shown, if the movable seat 51 moves to the right, the second pulley 54 moves away from the third pulley 55, and the first pulley 53 moves closer to the third pulley 55, so that the total winding length of the blocking belt 52 remains unchanged, and the blocking belt 52 on the movable seat 51 moves to the right relative to the material storage part 3 to open the bottom blanking opening of the material storage part 3; if the movable seat 51 moves to the left, the second pulley 54 moves closer to the third pulley 55, and the first pulley 53 moves away from the third pulley 55, similarly, the total winding length of the blocking belt 52 remains unchanged, and the blocking belt 52 on the movable seat 51 moves to the left relative to the material storage part 3 to close the bottom blanking opening of the material storage part 3. In other words, the structural design of the blocking blanking assembly 5 is ingenious, which can not only meet the requirements of the blocking belt 52 below the bottom blanking opening of the material storage part 3 to reciprocate relative to the material storage part 3 to open and close the bottom blanking opening of the material storage part 3, but also maintain the blocking belt 52 in a tensioned state. Furthermore, it can be achieved that the material blocking belt 52 opens the material drop opening at the bottom of the material storage component 3 by rolling it downward, and closes the material drop opening at the bottom of the material storage component 3 by expanding it outward, thereby reducing the extrusion and friction between the material blocking belt 52 and the material above, further reducing material damage, or even avoiding material damage.

[0047] Further, in this embodiment, the mobile driving member 56 includes a rotating arm 561, a connecting rod 562 and a rotating driving member 563 for driving the rotating arm 561 to rotate, and the connecting rod 562 is hinged between the rotating arm 561 and the moving seat 51; the material blocking and blanking assembly 5 also includes a guide rail 57, and the moving seat 51 is slidably arranged on the guide rail 57. The rotating arm 561, the connecting rod 562 and the moving seat 51 constitute a crank slider mechanism. The rotating movement of the rotating arm 561 drives the moving seat 51 to reciprocate in a linear motion. The structure is simple and the manufacturing is convenient.

[0048] Furthermore, in this embodiment, if Figure 5As shown, the material storage part 3 includes a material receiving plate 31 and a metering groove 32 that runs through the material receiving plate 31 from top to bottom, and the material blocking belt 52 is located below the metering groove 32. The metering groove 32 is used to measure the amount of material, and a full filling is a unit of loading.

[0049] Furthermore, in this embodiment, at least one side of the metering trough 32 is inclined, the receiving plate 31 is provided with a material drop trough 8 outside the metering trough 32, the feed port 321 of the metering trough 32 is higher than the material drop trough 8, and a guide surface 322 is provided between the feed port 321 and the material drop trough 8.

[0050] At least one side of the metering groove 32 is tilted inward or outward, so that the periphery of the metering groove 32 is convex upward to form a sharp edge structure. When the excess material is scraped flat, it will fall outward to avoid staying on the top of the metering groove 32 and being sheared. At the same time, the material that falls out is guided to the material drop chute 8 through the guide surface 322, which is also conducive to collection and refilling, reducing material waste. The materials that can be used for this material blocking and dropping mechanism include but are not limited to granules, tablets, pills and the like.

[0051] Furthermore, the metering trough 32 is inclined downward from the top feed opening 321, and the inclination includes inclination from the top feed opening 321 to the inside of the metering trough 32, and / or inclination from the top feed opening 321 to the outside of the metering trough 32. The feed opening 321 area of ​​the metering trough 32 is inclined to form a sharp edge, for example, the sharp edge is a sharp blade structure, that is, the top edge of the metering trough 32 is an acute angle. The sharp edges are on the same horizontal plane and enclose the top feed opening 321 of the metering trough 32. The width of the sharp edge is narrow, which reduces the contact surface with the material, thereby reducing the damage to the overflowed and swept materials, which is conducive to the refilling and use of the overflowed and swept materials, and reduces the waste of materials.

[0052] Furthermore, in this embodiment, a moving block 9 for changing the capacity of the metering tank 32 is movably provided on one side of the metering tank 32, and the moving block 9 is connected to a moving adjustment mechanism 91 for moving the moving block 9. By moving and adjusting the moving block 9, the volume in the metering tank 32 can be changed, thereby realizing the specification change of the material blocking and blanking mechanism to meet the requirements of different filling amount specifications.

[0053] Figure 5 and Figure 7 A first structural schematic diagram of the sharp edge is shown, that is, the side of the sharp edge facing the metering groove 32 is a vertical surface, and the other side is a curved surface. Figure 8 A second structural schematic diagram of the sharp edge is shown, in which one side of the sharp edge facing the metering groove 32 is an inclined surface, and the other side is a vertical surface.

[0054] Embodiment 2:

[0055] Figures 1 to 8An embodiment of the material metering and filling device of the utility model is also shown. The material metering and filling device of this embodiment includes a sweeping mechanism 4 and the material blocking and dropping mechanism of the first embodiment. The sweeping mechanism 4 is located above the material storage component 3 and is used to sweep the material on the top of the material storage component 3; the sweeping mechanism 4 includes a scraper 41 and a rotating drive assembly 42. The scraper 41 is swingably set above the material storage component 3 and is connected to the rotating drive assembly 42.

[0056] First, the material is transported to the metering trough 32; second, when the metering trough 32 is full of material, the sweeping mechanism 4 scrapes the material on the top of the metering trough 32; then, the movement of the blocking belt 52 opens the drop opening at the bottom of the metering trough 32, and the material in the metering trough 32 falls into the container below, realizing quantitative filling of the container. The rotary drive assembly 42 drives the scraper 41 to swing horizontally, scraping the material above the top of the metering trough 32. Compared with the linear reciprocating scraping, the horizontal shear force between the materials is small, and the materials are not easily damaged. The material metering and filling device includes a blocking and dropping mechanism, which has all the advantages of the blocking and dropping mechanism.

[0057] Embodiment three:

[0058] Figures 1 to 8 An embodiment of the material metering and filling system of the utility model is also shown. The material metering and filling system of this embodiment includes a silo 1, a vibrating feeding mechanism 2 and the material metering and filling device of embodiment 2. The vibrating feeding mechanism 2 is arranged between the silo 1 and the material storage component 3, and is used for vibrating and conveying the material falling from the silo 1 to the material storage component 3.

[0059] The silo 1 is no longer placed above the metering trough 32, and the falling material is vibrated and transported to the metering trough 32 by the vibrating feeding mechanism 2. Vibrating feeding can effectively avoid excessive accumulation of materials on the metering trough 32, which not only reduces the extrusion wear between materials, but also reduces the risk of materials sticking into blocks. The material metering and filling system includes a material metering and filling device, which has all the advantages of a material metering and filling device.

[0060] Furthermore, in this embodiment, the vibrating feeding mechanism 2 includes a feeding trough 21 and a vibrator 22 for vibrating the feeding trough 21. The discharge port at the bottom of the silo 1 is aligned vertically with the feed end of the feeding trough 21. The discharge end of the feeding trough 21 is connected to a guide trough 7, and the bottom end of the guide trough 7 is aligned vertically with the material storage component 3.
