[0028] The relevant details and working principles of the embodiments and the implementation mode of the present application are described below with reference to the drawings. The micro-pellet feeding mechanism of the soft capsule comprises a barrel 1, a flow dividing member 3 and a distributing component 2. The flow dividing member is provided with a closed material passage 33 with both ends unobstructed. The upper end of the material passage is an inlet, and the lower end is an outlet. The flow dividing member 3 can be an integral structure, but it is difficult to process the closed material passage with both ends unobstructed. The flow dividing member 3 comprises a flow dividing plate 31 and a cover plate 32. The front surface of the flow dividing plate 31 is provided with a groove that is open upward and downward. The cover plate 32 is installed on the front surface of the flow dividing plate. The cover plate encapsulates the groove, thereby forming the closed material passage 33 with both ends unobstructed, that is, the groove of the cover plate and the flow dividing plate together enclose the material passage. The flow dividing member adopts a split structure of the flow dividing plate 31 and the cover plate 32, which is easy to process and beneficial to inspection and maintenance. The cover plate is made of transparent material, and the staff can observe the distribution of the material in the material passage through the cover plate. The material passage is vertically inclined, and the material moves from top to bottom in the material passage by gravity. The outlet end 34 of the material passage gradually narrows and corresponds to the rubber forming cavity below. The outlet of the material passage converges, so that the output micro-pellets are concentrated into the rubber forming cavity, which prevents the micro-pellets from scattering and facilitates subsequent rubber sealing. In order to further prevent the output micro-pellets from scattering, the flow dividing member 3 is installed on the lifting seat 6. The lifting seat 6 can be lifted up and down on the rack, and the lifting of the lifting seat 6 can be driven by a cylinder. When the rubber is initially penetrated, the lifting seat 6 moves upward, driving the flow dividing member 3 to move upward, so that the distance between the flow dividing member 3 and the rubber forming roller below is increased, facilitating the penetration of the rubber between them. When the micro-pellets are distributed, the lifting seat 6 moves downward, and the outlet end 34 of the material passage is close to the rubber forming cavity below. The concentrated output micro-pellets directly enter the forming rubber groove, further preventing the micro-pellets from scattering.

[0029] The distributing component 2 is arranged between the hopper and the flow divider 3, and is used to quantitatively feed the micro-pellets in the hopper to the material channel. The distributing component 2 comprises an upper distributing plate 21, a metering plate 22 and a discharging plate 23. The upper distributing plate 21 and the discharging plate 23 are both mounted on the flow divider 3, and the upper distributing plate 21 and the discharging plate 23 are respectively provided with distributing holes 24 and discharging holes 26. The distributing holes 24 and the discharging holes 26 are arranged in staggered positions in the horizontal direction, the distributing holes 24 are communicated with the discharging port 11 of the hopper above, and the discharging holes 26 are communicated with the feeding port of the material channel below.

The metering plate 22 is provided with a metering hole 25, and the cavity of the metering hole 25 on the metering plate 22 is the amount of soft capsule feeding. In the feeding position, the metering hole 25 is communicated with the distributing hole 24 and is staggered with the discharging hole 26. In the discharging position, the metering hole 25 is communicated with the discharging hole 26, and the metering plate 22 blocks the distributing hole 24. The micro-pellets are quantitatively fed into the discharging hole 26 through the horizontal forward and backward movement of the metering plate 22, and then enter the material channel through the discharging hole 26, and finally the material channel feeds the quantitatively micro-pellets to the rubber forming device. The material channel is provided with a plurality of channels, and the number of the distributing holes 24, the discharging holes 26 and the metering holes 25 is consistent with the number of the material channels. The number of the material channels is consistent with the number of the rubber forming cavities below.

[0030] The distributing component 2 comprises a driving member for driving the metering plate 22 to move horizontally forward and backward. The driving member can adopt a pneumatic cylinder. In the embodiment, the driving member is a motor 5, and the motor is drivingly connected with the metering plate 22 through a transmission assembly 4. The transmission assembly comprises a cam 41 and a roller 43. The cam is connected with the output shaft of the motor, and the circumferential surface of the cam is provided with a cam groove 42. The cam groove 42 is floating forward and backward, i.e. the curve of the cam groove is floating forward and backward. The width of the cam groove 42 is matched with the outer diameter of the roller 43. The roller is arranged in the cam groove, and the roller 43 is connected with the metering plate 22. The metering plate is clamped by the upper distributing plate 21 and the discharging plate 23. Limiting baffle plates 27 are arranged on both sides of the metering plate, and the metering plate 22 can only move horizontally forward and backward. The motor 5 drives the cam to rotate, and the cam groove 42 drives the roller 43 and the metering plate 22 to move horizontally forward and backward.
