[0030] Figures 1 to 5 shows an embodiment of the pellet metering and feeding device of the present utility model. The pellet metering and feeding device of this embodiment includes a pellet hopper 1, a receiving box 2, a metering block 3, and a filling block 4 arranged in sequence from top to bottom. The filling block 4 is provided with a filling channel 41. The metering block 3 includes a first sub-block 31, a second sub-block 32, and a third sub-block 33. Quantitative holes 34 are provided between the first sub-block 31 and the third sub-block 33 and the second sub-block 32, and both the first sub-block 31 and the third sub-block 33 can move relative to the second sub-block 32 to adjust the size of the quantitative holes 34. A driving mechanism 5 is connected to the first sub-block 31, the second sub-block 32, and the third sub-block 33 for driving the three to move synchronously so that the quantitative holes 34 communicate with the receiving box 2 or the filling channel 41.

[0031] The process of this pellet metering and feeding device is as follows: First, the pellets fall from the pellet hopper 1 into the receiving box 2 for caching. Then, the driving mechanism 5 drives the first sub-block 31, the second sub-block 32, and the third sub-block 33 to move synchronously, making the quantitative holes 34 dock and communicate with the receiving box 2 and not communicate with the filling channel 41. The pellets in the receiving box 2 can then fall into the quantitative holes 34 until the quantitative holes 34 are filled. The filling amount in the filled quantitative holes 34 is the filling amount of the pellets in the capsule. Moreover, by moving the first sub-block 31 and the third sub-block 33 relative to the second sub-block 32, the size of the quantitative holes 34 can be adjusted to meet the filling requirements of different specifications of capsules. Finally, the driving mechanism 5 drives the first sub-block 31, the second sub-block 32, and the third sub-block 33 to move synchronously again, making the quantitative holes 34 dock and communicate with the filling channel 41 and not communicate with the receiving box 2. At this time, the receiving box 2 no longer drops pellets into the quantitative holes 34, and the pellets in the quantitative holes 34 are filled into the capsule through the filling channel 41.

[0032] This pellet metering and feeding device includes a first sub-block 31, a second sub-block 32, and a third sub-block 33. Adjustable quantitative holes 34 are provided between the first sub-block 31 and the third sub-block 33 and the second sub-block 32. Compared with the prior art, the number of rows of the quantitative holes 34 can be increased, and the filling of more than three rows of capsules can be achieved at one time, improving the filling efficiency and the overall production efficiency is better.

[0033] Further, in this embodiment, the metering hole 34 is a waist-shaped hole, and the relative movement directions of the first block 31 and the third block 33 relative to the second block 32 are the length directions of the waist-shaped hole. When the first block 31 and the third block 33 move away from the second block 32, the length of the waist-shaped hole becomes longer and the filling amount becomes larger; when the first block 31 and the third block 33 move closer to the second block 32, the length of the waist-shaped hole becomes shorter and the filling amount becomes smaller.

[0034] Further, as Figure 3 and Figure 5 shown, in this embodiment, the synchronous movement directions and relative movement directions of the first block 31, the second block 32, and the third block 33 are parallel. That is, the synchronous movement direction of the first block 31, the second block 32, and the third block 33 is the length direction of the metering hole 34.

[0035] Further, as Figure 4 and Figure 5 shown, in this embodiment, there are at least three rows of both the metering hole 34 and the filling channel 41. There are a plurality of discharge ports 21 provided on the receiving box 2 for communicating with the metering holes 34 in one-to-one correspondence. Each row of metering holes 34, filling channels 41, and discharge ports 21 are arranged at intervals along the relative movement direction of the first block 31, the second block 32, and the third block 33. The projections of the discharge ports 21 and the filling channels 41 on the horizontal plane are staggeredly arranged.

[0036] That is, the discharge ports 21 and the filling channels 41 are arranged in a staggered manner in the width direction of the metering hole 34. When the first block 31, the second block 32, and the third block 33 move synchronously until the metering hole 34 is docked and communicated with the discharge port 21, at this time, the metering hole 34 is not communicated with the filling channel 41, and the pellets in the receiving box 2 enter the metering hole 34 through the discharge port 21 for filling. Then, the first block 31, the second block 32, and the third block 33 move synchronously and reversely until the metering hole 34 is docked and communicated with the filling channel 41. At this time, the metering hole 34 is not communicated with the receiving box 2, and the pellets in the metering hole 34 are filled into the capsules through the filling channel 41.

[0037] Further, as Figure 4 shown, in this embodiment, there is an air hole 22 provided on the receiving box 2 that can be aligned and communicated with the filling channel 41. The air hole 22 is connected to the air supply mechanism. When the metering hole 34 is docked and communicated with the filling channel 41 for discharging materials, the air hole 22 blows air into the metering hole 34 to assist the pellets in falling.

[0038] Further, in this embodiment, the driving mechanism 5 includes a sliding seat 51 and a translation driving assembly 52. The translation driving assembly 52 is connected to the sliding seat 51 and is used to drive the sliding seat 51 to translate. The second sub-block 32 is fixed on the sliding seat 51, and the first sub-block 31 and the third sub-block 33 are both slidably arranged on the sliding seat 51 and are respectively located on both sides of the second sub-block 32. The translation driving assembly 52 drives the sliding seat 51 to translate, driving the first sub-block 31, the second sub-block 32, and the third sub-block 33 to move synchronously.

[0039] Further, as Figure 5 shown, in this embodiment, guide rails 511 are respectively arranged on both sides of the sliding seat 51. The first sub-block 31, the second sub-block 32, and the third sub-block 33 are all slidably arranged on the respective guide rails 511, and the second sub-block 32 is locked and fixed on the guide rail 511 through a locking member 512. This facilitates adjusting the relative positions and installation positions of the sub-blocks. Specifically, each sub-block is strip-shaped. The interval direction between adjacent metering holes 34 in each row of metering holes 34 is perpendicular to the guide rail 511. Concave portions and convex portions are alternately arranged on the opposite sides of each sub-block in a direction perpendicular to the guide rail 511, and the metering holes 34 are formed between the opposite concave portions and convex portions. The guide rails 511 make the sliding of the first sub-block 31 and the third sub-block 33 more stable, ensuring the stability of filling. Preferably, the locking member 512 is a locking screw.

[0040] Further, in this embodiment, a first movement adjusting member 53 for moving the first sub-block 31 relative to the second sub-block 32 and a second movement adjusting member 54 for moving the third sub-block 33 relative to the second sub-block 32 are arranged on the sliding seat 51. The first movement adjusting member 53 is rotatably connected to the second sub-block 32 and is threadedly connected to the sliding seat 51. The second movement adjusting member 54 is rotatably connected to the third sub-block 33 and is threadedly connected to the sliding seat 51. By rotating the first movement adjusting member 53, the first sub-block 31 can be driven to move relative to the second sub-block 32. By rotating the second movement adjusting member 54, the third sub-block 33 can be driven to move relative to the second sub-block 32.

[0041] Further, as Figure 2 shown, in this embodiment, the translation driving assembly 52 includes a lifting member 521 and a connecting member 522. The connecting member 522 is connected to the sliding seat 51, and the lifting member 521 is slidably engaged with the connecting member 522. The lifting member 521 moves up and down, driving the connecting member 522 to reciprocate horizontally, so as to drive the sliding seat 51 to reciprocate, thereby driving the first sub-block 31, the second sub-block 32, and the third sub-block 33 to move synchronously.

[0042] Further, in this embodiment, a push-pull groove is provided on the lifting member 521. The push-pull groove includes a first vertical section 524, an inclined section 525, and a second vertical section 526 that are sequentially connected. A rolling member 523 is provided on the connecting member 522, and the rolling member 523 is in rolling cooperation with the push-pull groove. Both the first vertical section 524 and the second vertical section 526 are vertically arranged, and the inclined section 525 is obliquely connected between the first vertical section 524 and the second vertical section 526 to play a role in horizontal pushing and pulling. When the rolling member 523 is located in the first vertical section 524, the metering hole 34 is in butt connection and communication with the material receiving box 2. When the rolling member 523 is located in the second vertical section 526, the metering hole 34 is in butt connection and communication with the filling channel 41. When the rolling member 523 slides along the inclined section 525, the sliding seat 51 moves horizontally. When the rolling member 523 slides in the first vertical section 524 and the second vertical section 526, the sliding seat 51 remains stationary.
