DETAILED DESCRIPTION

[0031] The following describes the relevant details and working principles of the implementation methods and embodiments of the utility model in conjunction with the accompanying drawings. The capsule conveying mechanism includes a transfer member 6, a conveying pipe 8 and a removal member 3. The transfer member 6 is provided with at least two capsule holes 5 for accommodating and locking capsules. The conveying pipe 8 is vertically arranged below the capsule hole 5. The vertical direction refers to the up and down direction, which is not limited to the vertical state but also includes the inclined state. A conveying pipe 8 is provided with at least two capsule inlets 7 and one capsule outlet 9. The capsule inlet 7 is at the top and is connected with the capsule hole 5 up and down. The capsule outlet 9 is at the bottom and is connected with the entrance of the next process. The removal member 3 rises and falls, and the removal member 3 is provided with a capsule pushing rod 4 corresponding to the capsule inlet 7, and the length of the capsule pushing rod 4 corresponding to the same conveying pipe 8 is different. In the removal state, the capsule pushing rod 4, the capsule hole 5, and the capsule inlet 7 are aligned vertically, the removal member 3 moves downward, and the capsule pushing rod 4 corresponding to the same delivery pipe 8 pushes the capsules in the corresponding capsule hole 5 in sequence, that is, the longer capsule pushing rod 4 is closer to the capsule hole 5 than the shorter capsule pushing rod 4, and thus the capsule in the capsule hole 5 is first pushed into the corresponding capsule inlet 7 below, and the shorter capsule pushing rod 4 pushes the capsule into the corresponding capsule inlet 7 later, so that the capsules are separated from the capsule hole 5 and enter the delivery pipe 8 from the corresponding capsule inlet 7 in sequence, and are sequentially output from the capsule outlet 9 of the delivery pipe 8. Although the delivery pipe 8 has at least two capsule inlets 7, multiple capsules entering from different capsule inlets 7 can be sequentially arranged in the delivery pipe 8 and sequentially output. Assuming that the speed of the sealing machine is twice that of the filling machine, the filling machine fills two capsules at the same time, the filled capsules are sent to the transfer station 2 through the transfer member 6, and the capsule pushing rod 4 pushes the capsules on the transfer member 6 into the conveying pipe 8 in turn, and is output through the conveying pipe 8 and enters the entrance of the sealing machine in turn. In this way, the speed of capsule filling and capsule sealing is just connected, and the sealing machine does not need to slow down to cooperate with the filling machine, which improves the speed of capsule processing as a whole.

[0032] The transfer member 6 is provided with at least two groups of capsule holes 5, one group of capsule holes 5 is provided with a plurality of capsule holes 5, and the number of conveying pipes 8 is consistent with the number of one group of capsule holes 5, and the capsule inlet 7 on each conveying pipe 8 is the same as the number of groups of capsule holes 5; in the removal working condition, the capsule holes 5 in the same group are arranged horizontally, and the capsule holes 5 in the same group are arranged vertically. In the figure, there are two groups of capsule holes 5 on the transfer member 6, each group of capsule holes 5 is provided with ten capsule holes 5, the number of the conveying pipes 8 is consistent with the number of capsule holes 5 in one group of capsule holes 5, and each conveying pipe 8 is provided with two capsule inlets 7. The removal member 3 is provided with two rows of capsule pushing rods 4, and the same row of capsule pushing rods 4 corresponds to a group of capsule holes 5, wherein the length of one row of capsule pushing rods 4 is longer than the length of the other row of capsule pushing rods 4. Then the filling machine is provided with two corresponding groups of filling capsule groups, each group of ten, and the sealing machine is provided with a group of capsule receiving inlets, a group of ten. Two rows of capsules are transferred at one time. The longer capsule pushing rod 4 first pushes one row of capsules into the conveying pipe 8, and the shorter capsule pushing rod 4 then pushes the other row of capsules into the conveying pipe 8. The conveying pipe 8 outputs the two rows of capsules in sequence.

[0033] The delivery pipeline 8 includes a main channel 14 and at least two shunt channels 13. The entrance of the shunt channel 13 is the capsule entrance 7. Two capsule entrances 7 have two shunt channels 13, and three capsule entrances 7 have three shunt channels 13. The exit of the shunt channel 13 is connected to the main channel 14. The exit of the main channel 14 is the capsule outlet 9, that is, the capsule enters from the capsule entrance 7 through the shunt channel 13 and then converges into the main channel 14, so that the capsule can be better guided and transported. The capsule entrance 7 is a vertical section for the capsule to enter vertically. The shunt channel 13 corresponding to the longer capsule pushing rod 4 has a capsule entrance 7 as a long vertical section for the capsule pushing rod 4 to extend into. The vertical section and the long vertical section provide a position for the capsule and the capsule pushing rod 4 to enter, so that the transfer operation is smooth. The main channel 14 is tilted, which can reduce the speed of the capsule falling in the main channel 14. If the falling speed is fast, the impact force when the capsule is output is large, which is easy to cause the capsule to be damaged. The speed of the downward movement is reduced, the capsule output is more stable, and the capsule quality is better. The spacing between the capsule outlets 9 of adjacent conveying pipes 8 is greater than the spacing between the capsule inlets 7. The conveying pipes 8 are used to increase the spacing between the capsules, which is consistent with the arrangement of the capsules in the next process.

[0034] The transfer member 6 is installed on a rotating plate 10, and the rotating plate 10 is horizontally rotated and arranged on a frame. The rotating plate 10 rotates horizontally to rotate the capsule hole 5 between the material receiving station 1 and the transfer station 2. At least two transfer members 6 are arranged on the rotating plate 10, and the transfer members 6 are evenly distributed along the circumferential direction of the rotating plate 10. Four are arranged in the figure. The removal member 3 is arranged at the transfer station 2, and the material receiving station 1 is provided with a capsule-pushing member, and the capsule-pushing member is lifted up and down, and the capsule-pushing member is provided with a capsule-pushing rod. An elastic ring 11 for locking the capsule is arranged in the capsule hole 5, and a mounting groove 12 is arranged on the wall of the capsule hole 5 of the transfer member 6, and the elastic ring 11 is placed in the mounting groove 12; the inner diameter of the elastic ring 11 is slightly smaller than the outer diameter of the capsule, and the capsule enters the capsule hole 5, and the elastic ring 11 is compressed and deformed and locks the capsule. At the material receiving station 1, the capsule pushing rod pushes the filled capsule into the capsule hole 5 of the transfer member 6, the elastic ring 11 locks the capsule, the rotating plate 10 rotates horizontally, and the transfer member 6 is rotated to the transfer station 2, the capsule pushing rod 4 moves downward, pushing the capsule in the capsule hole 5 downward, and the capsule leaves the capsule hole 5 and enters the conveying pipe 8.
