[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. The filling air bag is connected to the four air tubes, so that the air pressure at the connection point between the filling air bag and the four air tubes remains equal, causing the gas from the four air tubes to be discharged outward synchronously.

[0028] 2. As the gas passes through the conical tube and through the circular net fixedly connected to its top, it provides a certain buffering force to the falling capsule, thereby preventing the capsule from being excessively worn and cracked due to the long pipeline path and the influence of gravity.

[0029] 3. As the air flow rate increases, the air pressure inside the plastic tube increases and expands, thereby increasing the capacity of the capsule circulation and avoiding blockage caused by too many capsules. It also prevents static electricity from being generated between the capsules and the inner wall of the pipe, and between the capsules, causing the capsules to attract each other and stick together.

[0030] 4. The lower half of the traction ligament plate bends towards the center, thus serving two functions. The first function is to guide the downward flow of a large number of capsules to avoid collisions with the trachea and the conical tube. The second function is that a large number of holes are provided in the lower half of the traction ligament plate. Along with its upward deflection, the holes are aligned with the holes in the circular mesh in the same vertical line, increasing the flow range of the air flow and preventing excessive impact gas from escaping.

[0031] 5. By activating the first hydraulic rod to adjust the distance between the two arc-shaped plates, it serves to convey capsules of different thicknesses in a single row by sliding. By activating the second hydraulic rod, the friction plate moves left and right, causing the capsules to swing and preventing blockage at the conveying outlets of the two arc-shaped plates.

[0032] 6. By the downward movement of the double-link rod driving the roller support, the capsules originally conveyed by the conveyor belt are switched to be directly thrown downward for conveying. The conveyor belt allows the capsules to be conveyed in a single row by sliding without screening the capsules, while the capsules switched to be thrown downward enter the screening mechanism for screening.

[0046] Next, in combination with the accompanying drawings and specific embodiments, the present invention will be further described. It should be noted that on the premise of no conflict, any combination can be formed between the following described embodiments or technical features, and it should be known that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention

[0047] Please refer to Figures 1 to 12 , the present invention provides a technical solution: as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 shown, it includes a carrying and exchanging mechanism 2 for single - row sliding transportation or disordered sliding transportation of the formed capsules. Below the carrying and exchanging mechanism 2, there is a screening mechanism 3, and the screening mechanism 3 is used for screening the disordered sliding - transported capsules

[0048] The slow-flow mechanism 1 for slowly transporting and anti-blocking treatment of capsules is provided on the top of the carrying mechanism 2.

[0049] Among them, the slow-flow mechanism 1 includes a feeding pipe 11. A plastic pipe 14 is sleeved at the bottom end of the feeding pipe 11. The plastic pipe 14 has ductility and resilience. A clamp 12 is clamped on the outer side of the plastic pipe 14. The clamp 12 is used for connecting the plastic pipe 14 and the feeding pipe 11. A support rod 13 is fixedly connected to the outer side of the clamp 12, and the support rod 13 is fixedly connected to the top of the carrying mechanism 2;

[0050] The bottom end of the plastic pipe 14 is fixedly connected to a transition pipe 15;

[0051] A traction flexible plate 16 is used for guiding and orienting the falling capsules, and its lower half is flexible. The traction flexible plate 16 is fixedly connected to the inside of the transition pipe 15;

[0052] The bottom end of the transition pipe 15 is fixedly connected to a bottom connection pipe 10;

[0053] A flow dividing plate 101 is used for transporting the falling capsules in two batches and is fixedly connected to the inside of the bottom connection pipe 10;

[0054] An air pipe 17 is sleeved on the outer side of the transition pipe 15. A filling airbag 18 is fixedly connected to the outer end face of the air pipe 17. An inflation nozzle 19 is fixedly installed on the top of the filling airbag 18;

[0055] The top end of the air pipe 17 is fixedly connected to a conical pipe 102. A circular net 103 is fixedly connected to the top of the inner cavity of the conical pipe 102. The air pipe 17, the filling airbag 18, the inflation nozzle 19 and the conical pipe 102 are all interconnected; The formed capsules are put into the top end of the feeding pipe 11, and then the capsules will enter the plastic pipe 14. The feeding pipe 11 and the plastic pipe 14 are tightly connected by the clamp 12. In addition, the plastic pipe 14 is a flexible pipe similar to the plastic bag material and has certain resilience and ductility. Then, start the external blowing device connected to the inflation nozzle 19. At this time, the gas will flow through the filling airbag 18 and fill it. Finally, the overflowing gas will enter the air pipe 17. The filling airbag 18 is connected to four air pipes 17, so as to keep the air pressure at the connection parts of the filling airbag 18 and the four air pipes 17 equal, resulting in the synchronous outward discharge of gas from the four air pipes 17. Then the gas will pass through the conical pipe 102 and pass through the circular net 103 fixedly connected to its top to give a certain buffering force to the falling capsules, so as to avoid excessive wear and cracking of the capsules due to the too long pipeline path and the influence of gravity.

[0056] An inner groove 104 is opened on the outer side of the conical pipe 102, and a slider 105 is slidably fitted inside the inner groove 104;

[0057] The plugging plate 106 is used to adjust the inner cavity space of the conical tube 102 and is fixedly connected to the slider 105;

[0058] A top rod 107 is fixedly connected to the top of the plugging plate 106, and the top end of the top rod 107 is fixedly connected to the traction flexible plate 16; in addition, as the plugging plate 106 moves upward, the top rod 107 fixedly connected to its top will move upward accordingly. The top end of the top rod 107 is fixedly connected to the traction flexible plate 16, and the traction flexible plate 16 is flexible. Therefore, the lower half of the traction flexible plate 16 will bend towards the center, thus playing two roles. The first role is to traction the large number of capsules flowing downward to avoid collision with the trachea 17 and the conical tube 102; the second role is that a large number of holes are provided in the lower half of the traction flexible plate 16. Along with its upward deflection, the holes are in the same vertical line as the holes on the circular net 103, so as to increase the flow range of the air flow and avoid excessive escape of the impactful gas. In addition, the traction flexible plate 16 has an additional role, that is, when the number of input capsules is small, it reduces the degree of air flow escape and avoids excessive concentration of air flow, so that the capsules are suspended and cannot fall.

[0059] Both ends of the plugging plate 106 are symmetrically connected with telescopic rings 108. The two ends of the telescopic ring 108 are respectively connected to the plugging plate 106, so as to play a role of driving the other plugging plates 106 to move upward or downward synchronously when one plugging plate 106 moves upward or downward. The outer end surface of the plugging plate 106 is fixedly connected with an external connecting rod 109; when the number of capsules flowing through the plastic pipe 14 is excessive, the electric push rod 100 is started, so that the external connecting rod 109 connected to its output end will move upward, and the other end of the external connecting rod 109 is connected to the plugging plate 106. Therefore, the slider 105 connected to the plugging plate 106 will move upward along the inner groove 104. The inner groove 104 is opened on the surface of the conical tube 102, and the conical tube 102 is in a shape with the top inner diameter larger than the bottom inner diameter. Therefore, as the plugging plate 106 moves upward, the flow rate and range of the air flow discharged from the top of the conical tube 102 will be increased. As the air flow rate increases, the air pressure inside the plastic pipe 14 will increase and expand, thus playing a role of increasing the flow capacity of the capsules and avoiding blockage problems caused by excessive capsule quantity. At the same time, it also plays a role of avoiding static electricity generated by friction between the capsules and the inner wall of the pipe, as well as between the capsules, so that the capsules are attracted and adhered to each other.

[0060] The electric push rod 100 is used to adjust the height of the plugging plate 106 and is fixedly connected to the bottom end of the external connecting rod 109. The bottom end of the electric push rod 100 is fixedly connected to the inside of the transition pipe 15.

[0061] As Figure 7 , Figure 8 , Figure 9 , Figure 10 , Figure 11 and Figure 12 shown, the conveying mechanism 2 includes a cylinder body 21. The top of the cylinder body 21 is fixedly connected to the bottom connecting pipe 10 and the support rod 13 respectively. The cylinder body 21 is communicated with the bottom connecting pipe 10, and the bottom of the cylinder body 21 is fixedly connected to the screening mechanism 3. An elastic tube 22 is arranged inside the cylinder body 21, and the elastic tube 22 is fixedly connected to the bottom of the bottom connecting pipe 10;

[0062] A vertical rail 23 is fixedly connected inside the cylinder body 21. A moving block 24 is slidably fitted inside the vertical rail 23. The outer end face of the moving block 24 is fixedly connected to a double connecting rod 25. One end of the double connecting rod 25 far from the moving block 24 is fixedly connected to a roller support 26. A servo motor 27 is fixedly installed on the outside of the roller support 26. The output end of the servo motor 27 is connected to a first roller 28 through a coupling. The first roller 28 is rotatably installed inside the roller support 26;

[0063] The outside of the first roller 28 is drivingly connected to a conveyor belt 29. The inner cavity of the conveyor belt 29 is drivingly connected to a second roller 20 on the side far from the first roller 28. The conveyor belt 29 is used for conveying and processing capsules;

[0064] Both ends of the roller support 26 are symmetrically connected to a first hydraulic rod 201 respectively. The output end of the first hydraulic rod 201 penetrates through the surface of the roller support 26 and is fixedly connected to an arc-shaped plate 202. The arc-shaped plate 202 is used for arranging the capsules on the conveyor belt 29 in a single row;

[0065] A friction plate 203 is slidably adapted to the bottom of the arc-shaped plate 202. The friction plate 203 is used to swing the capsules being conveyed from side to side. The outer end face of the friction plate 203 is fixedly connected to a second hydraulic rod 204, and the end of the second hydraulic rod 204 away from the friction plate 203 is fixedly connected to the inner side of the roller support 26. Subsequently, the capsules discharged from the bottom connection pipe 10 will enter the cylinder body 21 and accumulate on the conveyor belt 29. Immediately afterwards, the servo motor 27 is started, so that the first roller 28 connected to its output end will rotate within the roller support 26 and drive the conveyor belt 29 to move, thereby realizing the conveying process of the capsules. A first hydraulic rod 201 is fixedly installed on the outer side of the roller support 26, and the output end of the first hydraulic rod 201 is connected to the arc-shaped plate 202. Therefore, the first hydraulic rod 201 can be started to adjust the distance between the two arc-shaped plates 202, so as to play a role in single-row sliding conveying of capsules with different thicknesses. The inner wall of the roller support 26 is connected to the second hydraulic rod 204, and the output end of the second hydraulic rod 204 is connected to the friction plate 203. Moreover, the friction plate 203 is slidably adapted to the bottom of the arc-shaped plate 202. Therefore, the left and right movement of the friction plate 203 makes the capsules swing, preventing the capsules from being blocked at the conveying openings of the two arc-shaped plates 202.

[0066] A flow pipe 205 is fixedly connected to the bottom end of the arc-shaped plate 202, and elastic cover plates 206 are fixedly connected to the outer sides of the arc-shaped plate 202 and the flow pipe 205.

[0067] A tension rope 207 is fixedly connected to the outer side of the elastic tube 22. The tension rope 207 penetrates through the inner side of the cylinder body 21 and extends to the outside. A fixed pulley 208 is drivingly connected to the outer side of the tension rope 207. A pulley support rod 209 is rotatably connected to the central part of the fixed pulley 208. The pulley support rod 209 is fixedly connected to the outer side of the cylinder body 21. A cross bar 200 is fixedly connected to the bottom end of the tension rope 207. An extension rod 31 is fixedly connected to the end of the cross bar 200 away from the tension rope 207. The extension rod 31 is fixedly connected to the moving block 24 and is slidably fitted to the outer side of the cylinder body 21. A large number of friction protrusions are arranged on the surface of the moving block 24. Therefore, the moving block 24 will not automatically move downward along the vertical rail 23 without being acted by an external force. By driving the moving block 24 to move downward along the vertical rail 23 by external power, the double link 25 connected to its outer end will drive the roller support 26 to move downward. At the same time, the extension rod 31 fixedly connected to the other end of the double link 25 will drive the cross bar 200 to move downward. The top of the cross bar 200 is connected to the tension rope 207. Therefore, the tension rope 207 will take the point of contact with the fixed pulley 208 as a fixed point and drive the elastic tube 22 connected to the other end thereof to move outward and downward. The elastic tube 22 is elastic and is fixedly connected to the bottom end of the bottom connecting pipe 10, so as to play a role in switching the capsules originally conveyed by the conveyor belt 29 to direct downward throwing and conveying. The conveyor belt 29 will make the capsules slide in a single row for conveying and will not screen the capsules, while the capsules switched to downward throwing and conveying will enter the screening mechanism 3 for screening.

[0068] When the present invention is in use: First, the formed capsules are put into the top end of the feeding pipe 11, and then the capsules will enter the plastic pipe 14. The feeding pipe 11 and the plastic pipe 14 are tightly connected by a clamp 12. In addition, the plastic pipe 14 is a ductile pipe similar to the material of a plastic bag and has certain resilience and ductility. Then, an external blowing device connected to the air inlet nozzle 19 is started. At this time, the gas will flow through the filling air bag 18 and fill it. Finally, the overflowing gas will enter the air pipe 17, and then the gas will pass through the conical pipe 102 and pass through the circular net 103 fixedly connected to the top thereof to give a certain buffering force to the falling capsules. When the number of capsules flowing through the inside of the plastic pipe 14 is too large, the electric push rod 100 is started, so that the external rod 109 connected to its output end will move upward. The other end of the external rod 109 is connected to the blocking plate 106. Therefore, the slider 105 connected to the blocking plate 106 will move upward along the inner groove 104. The inner groove 104 is opened on the surface of the conical pipe 102, and the conical pipe 102 is in a shape with a top inner diameter larger than the bottom inner diameter. Therefore, as the blocking plate 106 moves upward, the flow rate and range of the air flow discharged from the top of the conical pipe 102 will be increased. As the air flow rate increases, the air pressure inside the plastic pipe 14 will increase and expand.

[0069] In addition, as the plugging plate 106 moves upward, the ejector rod 107 fixedly connected to its top will move upward accordingly. The top end of the ejector rod 107 is fixedly connected to the traction ligament plate 16, and the traction ligament plate 16 is resilient. Therefore, the lower half of the traction ligament plate 16 will bend towards the center to achieve the traction treatment of the downward flow of a large number of capsules.

[0070] Subsequently, the capsules discharged from the bottom connecting pipe 10 will enter the cylinder body 21 and accumulate on the conveyor belt 29. Immediately afterwards, the servo motor 27 is started, so that the first roller 28 connected to its output end will rotate in the roller support 26 and drive the conveyor belt 29 to move, thereby realizing the conveying treatment of the capsules. A first hydraulic rod 201 is fixedly installed on the outer side of the roller support 26, and the output end of the first hydraulic rod 201 is connected to the arc plate 202. Therefore, the first hydraulic rod 201 can be started to adjust the distance between the two arc plates 202 to perform single-row sliding conveying treatment on capsules of different thicknesses. The inner wall of the roller support 26 is connected to the second hydraulic rod 204, and the output end of the second hydraulic rod 204 is connected to the friction plate 203. The friction plate 203 is slidably fitted to the bottom of the arc plate 202. Therefore, the left and right movement of the friction plate 203 makes the capsules swing to prevent the capsules from being blocked at the conveying ports of the two arc plates 202.

[0071] A large number of friction protrusions are provided on the surface of the moving block 24. Therefore, the moving block 24 will not automatically move downward along the vertical rail 23 without external force. By driving the moving block 24 to move downward along the vertical rail 23 through external power, the double-link rod 25 connected to its outer end will drive the roller support 26 to move downward. At the same time, the extension rod 31 fixedly connected to the other end of the double-link rod 25 will drive the cross bar 200 to move downward. The top of the cross bar 200 is connected to the tension rope 207. Therefore, the tension rope 207 will take the point of contact with the fixed pulley 208 as a fixed point and drive the elastic tube 22 connected to the other end to move outward and downward. The elastic tube 22 is elastic and is fixedly connected to the bottom end of the bottom connecting pipe 10, so that the capsules originally conveyed by the conveyor belt 29 will be switched to direct downward throwing and conveying.

[0072] The above embodiments are only the preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Those of ordinary skill in the art, starting from the above concept, without creative labor, all kinds of transformations made will fall within the scope of protection of the present invention.
