For example, a Chinese invention patent with authorization announcement number CN104434528B discloses an automatic pill making machine, which includes a base and a casing fixed to the base, a pill making mechanism is arranged inside the casing, a controller, a strip shifting device, a feeding mechanism and a medicine strip cutting device are arranged at the upper end of the casing, the feeding mechanism is a belt conveyor, the strip shifting device is installed on one side of the belt conveyor, the belt conveyor crosses the controller and the medicine strip cutting device connected by a cylinder, the medicine strip cutting device is arranged at the upper end of the feeding mechanism, the medicine strip cutting device includes a tool support frame, a tool mounting frame, a tool, a connecting shaft and an adjusting tool clamp, the tool support frame is connected and installed on the casing, a tool mounting frame is provided on the tool support frame, a mounting hole is provided at the front end of the tool mounting frame, and a connecting shaft and a tool are installed in the mounting hole through a bearing.

[0004] After the pills are made, the existing Chinese medicine pill making machines need to centrally dry or coat the pills before packaging. Such Chinese medicine pill making machines are only suitable for making finished pills with a relatively dry surface and low moisture content. However, for finished pills such as Sanfutie, which have a high moisture content and high viscosity, they do not need to be dried after production, nor can they be piled up in large quantities. They must be packaged one by one as quickly as possible, and the existing pill making machines cannot meet this requirement. Summary of the invention

[0005] The object of the present invention is to provide a pill packaging device for a pill making machine which can automatically package formed pills one by one in real time.

[0006] To achieve the above-mentioned object of the invention, the technical solution of the present invention is as follows:

[0009] Using packaging to cover pills can effectively extend the shelf life of the pills and prevent the pills from becoming dry and hard as the storage time increases. When using the pills, there is no need to tear open the packaging, just stick the pills with the packaging directly on the patient's skin. Packaging materials such as oil paper or gauze will not affect the release of active ingredients in the pills, and prevent the pills from directly contacting the patient's skin, which greatly reduces the sticky feeling brought by the pills and improves the user experience.

[0010] In the pill packaging device of the pill making machine, the pill packaging mechanism includes a second ball rolling cylinder fixedly mounted on the frame, the pill inlet is at the top of the second ball rolling cylinder, and the discharge port is at the bottom of the second ball rolling cylinder; a spiral ball rolling channel connecting the pill inlet and the discharge port is formed in the second ball rolling cylinder. Before falling into the pill inlet, the pills first fall onto the packaging member, and the pills carrying the packaging member will fall along the spiral ball rolling channel. During the falling process, the packaging member will not only gradually wrap the entire outer surface of the pills, but also the pills can be further processed and formed.

The horizontal movable seat is provided with two clamping plates on one side facing the gauze suction channel and an opening and closing driving structure for driving the two clamping plates to open and close.

[0020] The cloth feed rollers should be set as close to the frame as possible, and a corresponding cloth feed entrance should be set on the frame; or the cloth feed rollers should be directly set in the cloth feed entrance so that the user can insert the free end of the gauze roll (i.e. the gauze head) between the cloth feed rollers outside the frame. In this way, when the cloth feed rollers rotate, the gauze head can be sucked into the frame.

[0021] In the pill packaging device of the pill making machine, the translation drive structure comprises a left fixed seat and a right fixed seat arranged on the top surface of the bracket, the left fixed seat and the right fixed seat are respectively located on both sides of the pill inlet, at least one pair of horizontal screw rods are rotatably connected between the left fixed seat and the right fixed seat, and a translation motor for driving the horizontal screw rod to rotate circumferentially is provided on the bracket;

[0022] The horizontal moving seat is threadedly mounted on the horizontal lead screw.

[0023] The two horizontal screw rods can be driven by a translation motor respectively, or by the same translation motor. When the same translation motor is used, a gear set can be arranged in the left fixed seat to realize the transmission between the translation motor output shaft and the two horizontal screw rods.

[0024] In the pill packaging device of the pill making machine, two supporting plates are arranged opposite to each other on one side of the horizontal movable seat facing the gauze suction channel, the clamping plate is arranged between the two supporting plates and slidably cooperates with the supporting plates, and the two clamping plates are arranged up and down;

[0025] The opening and closing driving structure comprises a steering gear fixedly mounted on the supporting plate, and a transmission member for driving the two clamping plates to move toward or away from each other is arranged between the steering gear's rudder bar and the clamping plates.

[0026] When the rudder stock rotates, the transmission member can convert the circumferential rotation of the rudder stock into the linear movement of the clamping plate, driving the two clamping plates to move toward or away from each other, realizing the opening and closing of the clamping plates, and achieving the purpose of clamping or releasing the gauze.

[0027] In the pill packaging device of the above-mentioned pill making machine, the gauze cutting assembly includes a lifting seat slidably mounted on a bracket and a lifting driving structure for driving the lifting seat to rise and fall, and a cutter is provided on the side of the lifting seat facing the pill inlet.

[0031] The gauze conveying unit is used to convey the gauze to the top opening of the expansion guide tube, and the oil paper conveying unit is used to convey the oil paper into the radial through opening and cover the channel opening of the axial channel.

[0032] This not only allows the oil paper conveying unit and the gauze conveying unit to staggered convey the corresponding packages without interfering with each other, but also prevents the oil paper or gauze from being displaced during the conveying process due to excessive spacing between the oil paper conveying unit or the gauze conveying unit and the pill entrance.

[0033] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0034] (1) The pill packaging device of the present invention is directly arranged at the pill outlet of the pill making mechanism, wherein the package conveying mechanism can deliver the packages one by one to between the pill outlet and the pill inlet, and the pills made by the pill making mechanism fall one by one from the pill outlet to the packages between the pill outlet and the pill inlet, and the pills coated with the packages fall directly into the pill inlet and are further rolled into shape in the pill packaging mechanism; due to the coating of the packages, a small amount of stacking of the pills falling from the discharge port will not affect the appearance of the pills; the fully automatic pill making and packaging of soft pills such as Sanfutie is realized, and the production efficiency of soft pills such as Sanfutie is greatly improved.

[0035] (2) Using packaging materials to cover pills can effectively extend the shelf life of the pills and prevent the pills from becoming dry and hard as the storage time increases. When using the pills, there is no need to tear open the packaging materials. The pills with packaging materials can be directly applied to the patient's skin.

[0047] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0048] Example 1

[0049] like Figure 1 The fully automatic pill making machine shown in the figure is particularly suitable for preparing pills with high moisture content and large surface viscosity, such as Sanfu plaster. The fully automatic pill making machine comprises a frame 1. According to the pill making process, the frame 1 is provided with a medicine mixing mechanism 2, a cutting mechanism 3, a pill making mechanism 4 and a pill packaging device of this embodiment in sequence. The pill packaging device comprises a package conveying mechanism 5 and a pill packaging mechanism 6.

[0050] Among them, Figure 1 and Figure 2 As shown, the medicine mixing mechanism 2 is used to mix and extrude the various ingredients of the pills. The medicine mixing mechanism 2 includes a spiral extrusion barrel 21 fixedly connected to the frame 1, the spiral extrusion barrel 21 is horizontally arranged in the frame 1, and a spiral extrusion rod 22 is rotatably installed in the spiral extrusion barrel 21, and a mixing motor 23 for driving the spiral extrusion rod 22 to rotate is installed on the frame 1.

[0051] like Figure 2 Shown, combined Figure 1 It can be seen that at one end of the spiral extruder 21 close to the mixing motor 23, a feed port is provided on the top surface of the spiral extruder 21, and a feed pipe 24 extending to the outside of the frame 1 is installed at the feed port. The feed pipe 24 used in this embodiment is Y-shaped, and one opening 24a of the Y-shaped feed pipe 24 is used to fill the powder, and the other opening 24b is used to pour the liquid. On this side of the pipe, a valve 24c and a scale can be set, the scale is convenient for measurement, and the valve 24c is used to control the flow rate of the liquid.

[0052] Of course, a simple straight feed tube 24 may also be used to measure the liquid in advance and then pour it in.

[0053] The medicinal materials entering the spiral extrusion cylinder 21 are mixed and moved to the other end of the spiral extrusion cylinder 21 under the action of the spiral extrusion rod 22. Figure 2 As shown, a discharge pipe 25 is connected to the end surface of the spiral extruder 21 away from the mixing motor 23, and the discharge pipe 25 has a pill extrusion port 25a facing the pill making mechanism 4; the uniformly mixed medicinal materials are extruded from the pill extrusion port 25a to form pills.

[0054] like Figure 2 As shown, in this embodiment, the pill making mechanism 4 includes a first pill rolling cylinder 41 rotatably connected via a bearing frame 1, and the first pill rolling cylinder 41 is funnel-shaped, and thus has a pill inlet 41a at the top of the first pill rolling cylinder 41, and a pill outlet 41b at the bottom of the first pill rolling cylinder 41. In order to allow the pills to directly enter the first pill rolling cylinder 41 from the pill inlet 41a, a cutting mechanism 3 for cutting off the pills extruded from the pill extrusion outlet 25a is also provided at the pill inlet 41a.

[0055] Depend on Figure 2It can be seen that the cutting mechanism 3 of the present embodiment includes a tool holder 31 rotatably connected to the frame 1 through a bearing, and the tool holder 31 is conical, and is located above the first ball rolling cylinder 41 and is coaxially arranged with the first ball rolling cylinder 41; the flared end of the conical tool holder 31 faces the first ball rolling cylinder 41 and has a cylindrical tail wing 32, and the cylindrical tail wing 32 is formed with a first cutter 32a in the same circumferential direction and an escape opening 32b connecting the drug bolus extrusion port 25a and the drug bolus inlet 41a; the movement radius of the first cutter 32a is equivalent to the radius of the drug bolus inlet 41a, and the drug bolus extrusion port 25a of the spiral extrusion cylinder 21 is located on the circular movement trajectory of the cutting blade.

[0056] Since the movement radius of the first cutter 32a is equivalent to the radius of the drug bolus entrance 41a, the first cutter 32a moves circumferentially around the drug bolus entrance 41a during the rotation of the cutter holder 31. The drug bolus extrusion outlet 25a is also on the circular movement trajectory of the first cutter 32a. When the first cutter 32a rotates to the drug bolus extrusion outlet 25a, the drug bolus is cut off; when the first cutter 32a is at other positions, the drug material mixing mechanism 2 slowly extrudes the drug bolus. By controlling the rotation speed of the cutter holder 31 and the drug bolus extrusion speed, the size of the drug bolus can be controlled.

[0057] The pill extrusion port 25a is arranged at the side of the pill inlet 41a, so as to ensure that the pills falling into the first ball rolling cylinder 41 have sufficient molding time.

[0058] The first ball rolling cylinder 41 and the knife holder 31 need to be driven to rotate circumferentially to play their functions. In order to save power, in this embodiment, the first ball rolling cylinder 41 and the knife holder 31 are driven by the same driver.

[0059] like Figure 3 Shown, combined Figure 1 It can be seen that the pill making mechanism 4 also includes a pill making motor 42 for driving the first pill rolling cylinder 41 to rotate, and the first pill rolling cylinder 41 is driven by the output shaft of the pill making motor 42 through the pill making transmission gear pair 43; and the tool holder 31 is rotatably matched with the first pill rolling cylinder 41, and the tool holder 31 is driven by the output shaft of the pill making motor 42 through the cutting transmission gear pair 33.

[0060] Specifically, the pill outlet 41b of the first pill rolling cylinder 41 is provided with an extension tube 44, the pill making transmission gear pair 43 includes a pill making large gear 43a fixedly mounted on the output shaft of the pill making motor 42, and a pill making small gear 43b fixedly mounted on the extension tube 44, the pill making small gear 43b meshing with the pill making large gear 43a; and the top of the knife holder 31 is provided with a connecting rod 34 rotatably connected to the frame 1, the cutting transmission gear pair 33 includes a cutting small gear 33a fixedly mounted on the output shaft of the pill making motor 42, and a cutting large gear 33b fixedly mounted on the connecting rod 34, the cutting large gear 33b meshing with the cutting small gear 33a. It can be seen from this that the transmission ratio of the pill making transmission gear pair 43 is relatively small, so the rotation speed of the first pill rolling cylinder 41 is relatively fast; while the transmission ratio of the cutting transmission gear pair 33 is relatively large, so the rotation speed of the knife holder 31 and the first cutter 32a is relatively slow. This ensures that after the pills in the first ball rolling cylinder 41 are processed and formed and leave the pill outlet 41b, the first cutter 32a on the knife holder 31 cuts off another pill, thereby preventing multiple pills from entering the first ball rolling cylinder 41 at the same time and sticking to each other.

[0061] like Figure 3 As shown, in this embodiment, the rotational cooperation between the first ball rolling cylinder 41 and the tool holder 31 is as follows: an annular groove 41c is formed on the first ball rolling cylinder 41 at the outer edge of the opening of the pill entrance 41a, a ball 41d is provided at the bottom of the annular groove 41c, and the cylindrical tail wing 32 is embedded in the annular groove 41c.

[0062] The first ball rolling cylinder 41 of this embodiment can be made of stainless steel, and ensure that the inner wall has good anti-sticking properties. In order to facilitate the regular lubrication or cleaning of the inner wall of the first ball rolling cylinder 41, such as Figure 3 As shown, in this embodiment, the connecting rod 34 has a central channel 34a connected to the inner space of the first ball rolling cylinder 41, the top end of the connecting rod 34 is connected to the anti-sticking cleaning mechanism, and a nozzle (not shown in the figure) is installed at the liquid outlet of the central channel 34a.

[0063] The specific structure of the anti-sticking cleaning mechanism is not shown in the figure of this embodiment, but it may include a pump and a water tank and / or an oil tank connected to the connecting rod 34. The pump can pump cleaning agents such as water and / or lubricants such as oil into the central channel 34a, and the nozzle sprays the cleaning agent and / or lubricant onto the inner wall of the first ball rolling cylinder 41.

[0064] In theory, the package conveying mechanism 5 and the pill packaging mechanism 6 are arranged below the pill outlet 41b. Figure 1As shown, in order to make the structure of the whole machine more compact, the present embodiment arranges the package conveying mechanism 5 and the pill packaging mechanism 6 side by side with the pill making mechanism 4, and adopts the pill transfer mechanism 7 to convey the pills falling from the pill outlet 41b to the top of the package conveying mechanism 5 and the pill packaging mechanism 6.

[0065] like Figure 1 As shown, the pill transport mechanism 7 includes an active roller 71 and a driven roller 72 which are rotatably connected to the frame 1, and a conveyor belt 73 is sleeved between the active roller 71 and the driven roller 72. The active roller 71 is located at the high side, close to the packaging conveying mechanism 5, and the driven roller 72 is located at the low side, close to the pill making mechanism 4, so the conveyor belt 73 is inclined, and the pills are transported from the low side to the high side. In order to prevent the pills from rolling down, the surface of the conveyor belt 73 is spaced apart with arc-shaped baffles 74. A conveying motor 75 connected to the active roller 71 is also installed on the frame 1.

[0066] like Figure 3 Shown, combined Figure 1 It can be seen that in order to prevent the outlet of the extension tube 44 from being directly opposite to the conveyor belt 73, causing the pills to rush directly to the conveyor belt 73 and cause the pills to be deformed due to the impact, a curved pipe 45 is installed at the end of the extension tube 44. The curved pipe 45 can not only slow down the downward speed of the pills and reduce the downward momentum of the pills; but also the outlet of the curved pipe 45 is directed toward the discharge end of the conveyor belt 73, which can further shorten the distance between the outlet of the curved pipe 45 and the conveyor belt 73, ensuring that the pills will not be deformed after falling onto the conveyor belt 73.

[0067] like Figure 4 and Figure 5 As shown, the pill packaging mechanism 6 includes a second ball rolling cylinder 61 fixedly mounted on the frame 1, the second ball rolling cylinder 61 has a pill inlet 61a at the top and a discharge port 61b at the bottom, and a spiral ball rolling channel 61c connecting the pill inlet 61a and the discharge port 61b is formed inside the second ball rolling cylinder 61.

[0068] like Figure 6 and Figure 7 Shown, combined Figure 4 It can be seen that the pill inlet 61a of the second ball rolling cylinder 61 is provided with an expansion guide tube 63 through the base 62. The bottom of the base 62 has an embedding groove 62a for facilitating the base 62 to be mounted on the second ball rolling cylinder 61, and the center of the base 62 is provided with an axial channel 62b connecting the expansion guide tube 63 and the pill inlet 61a, and the discharge end of the conveyor belt 73 is located above the expansion guide tube 63.

[0069] like Figure 4As shown, in this embodiment, the package conveying mechanism 5 includes a bracket 51 fixedly connected to the frame 1, and the bracket 51 is arranged around the second ball rolling cylinder 61; the bracket 51 is provided with an oil paper conveying unit 52 and a gauze conveying unit 53, wherein the oil paper conveying unit 52 is used to convey the oil paper to the pill entrance 61a, and the gauze conveying unit 53 is used to convey the gauze to the pill entrance 61a. The oil paper conveying unit 52 and the gauze conveying unit 53 can be started at the same time and used in turn to alternately convey the oil paper or gauze to the pill entrance 61a, or the oil paper conveying unit 52 or the gauze conveying unit 53 can be started separately.

[0070] Among them, Figure 6 As shown, the oil-paper conveying unit 52 conveys the oil-paper in the same manner as the paper feeding mechanism in the printer, and reference may be made to the automatic paper feeding printer disclosed in publication number CN109572247A; the paper-feeding unit 52 comprises a paper-feeding machine body 521 fixedly mounted on a bracket 51, and the paper-feeding machine body 521 is provided with a paper inlet 521a and a paper outlet 521b, a paper-feeding channel is formed between the paper inlet 521a and the paper outlet 521b, and a plurality of paper-feeding rollers are arranged in the paper-feeding machine body 521 for driving the oil-paper to move along the paper-feeding channel.

[0071] like Figure 6 As shown, a paper storage platform 522 is provided at the paper inlet 521a of the paper feeder body 521, and a paper feeding cam is provided at the paper outlet end of the paper storage platform 522; when the raised portion of the paper feeding cam rotates one circle toward the paper storage platform 522, a piece of oil paper is sucked and poured into the paper feeding channel until the oil paper is delivered from the paper outlet 521b.

[0072] On the paper outlet 521b side of the paper feeder body 521, a radial through hole 62c is provided on the base 62, and the radial through hole 62c is connected to the axial channel 62b, and the oil paper is fed into the radial through hole 62c and covers the channel opening of the axial channel 62b. When the pills fall from the conveyor belt 73, the pills pass through the expanded guide tube 63 and the axial channel 62b and fall on the oil paper. The oil paper and the pills enter the pill entrance 61a together and go down along the spiral ball rolling channel 61c. During the downward process, the oil paper gradually wraps the pills completely, and the pills are further processed and formed until the finished pills fall from the outlet 61b. Figure 1 As shown, below the discharge port 61b, a drawer-type receiving box 8 is provided in the frame 1 for receiving the finished pills dropped from the discharge port 61b.

[0073] like Figure 8 and Fig. 9 Shown, combined Figure 1 and Figure 4It can be seen that the gauze conveying unit 53 includes a reel 54 rotatably connected to the frame 1, and a gauze roll is wound on the reel 54; the reel 54 can be arranged inside the frame 1 or outside the frame 1. Being arranged outside the frame 1 is more conducive to observing the amount of gauze used and facilitating timely replacement of a new gauze roll.

[0074] The frame 1 is provided with a fixed pulling assembly 55 and a movable pulling assembly 56 respectively located on opposite sides of the flared guide tube 63, wherein the fixed pulling assembly 55 is close to the reel 54 and is used to clamp and pull the gauze, and the frame 1 is provided with a first gauze entrance 11 for the edge gauze to enter the frame 1. In this embodiment, the fixed pulling assembly 55 includes a pair of cloth feeding rollers 551 rotatably connected to the bracket 51, and a gauze suction channel 553 is formed between the pair of cloth feeding rollers 551; and a cloth feeding motor 552 is provided on the bracket 51 for driving the pair of cloth feeding rollers 551 to rotate and suck the gauze. The pair of cloth feeding rollers 551 is close to the first gauze entrance 11, so that the gauze head can be inserted into the gauze suction channel 553 outside the frame 1.

[0075] like Figure 8 and Fig. 9 As shown, the movable pulling assembly 56 includes a horizontal movable seat 561 slidably mounted on the bracket 51 and a translation driving structure 562 for driving the horizontal movable seat 561 to undergo horizontal displacement.

[0080] When the servo 565a is started, the steering wheel 565c rotates synchronously with the rudder bar 565b, and a twist also occurs between the steering wheel 565c and the steering wheel connecting rod 565d; when rotating in the forward direction, the steering wheel connecting rod 565d drives the two clamps 564 to move toward each other and clamp the gauze head; when rotating in the reverse direction, the steering wheel connecting rod 565d drives the two clamps 564 to move away from each other and open to release the gauze head.

[0081] like Figure 8 and Fig. 9 As shown, the bracket 51 is also provided with a gauze cutting assembly 57 on the side of the fixed pulling assembly 55, and the gauze cutting assembly 57 includes a lifting and moving seat 571 slidably mounted on the bracket 51 and a lifting and driving structure 572 for driving the lifting and moving seat 571 to rise and fall, and the lifting and moving seat 571 is provided with a cutter on the side facing the pill inlet 61a. In this embodiment, the lifting and driving structure 572 includes two vertical screw rods 572a rotatably mounted on the left fixed seat 562a, and the lifting and moving seat 571 is threadedly mounted on the vertical screw rod 572a; the left fixed seat 562a is also provided with a lifting motor 572b for driving the vertical screw rod 572a to rotate circumferentially.

[0082] Similarly, the two vertical screw rods 572a can be driven by a lifting motor 572b respectively, or by the same lifting motor 572b. When the same lifting motor 572b is used for driving, a gear set can be provided in the left fixed seat 562a to realize the transmission between the output shaft of the lifting motor 572b and the two vertical screw rods 572a.

[0083] The working principle of a fully automatic pill making machine in this embodiment is as follows:

[0084] The weighed medicine powder and liquid are added into the spiral extruder 21 from the feed pipe 24, and the mixing motor 23 is started to extrude the mixture from the pill extrusion port 25a; the pill making motor 42 is started, the first pill rolling cylinder 41 rotates at a relatively high speed, and the knife holder 31 rotates at a relatively low speed; the first cutter 32a cuts off the pill extruded from the pill extrusion port 25a, and the pill falls into the first pill rolling cylinder 41 from the avoidance port 32b, and after being rolled into shape in the first pill rolling cylinder 41, it falls from the pill outlet 41b onto the conveyor belt 73; every time a pill is rolled into shape, the first cutter 32a rotates one circle, and cuts off another pill, and the cycle repeats;

[0085] The conveying motor is started, and the conveying belt 73 moves upward to convey the pills to the pill packaging mechanism 6;

[0086] When the pills are packaged with oil paper, the oil paper conveying unit 52 is started, and the paper feeding cam and the paper feeding roller pair convey the oil paper on the paper storage platform 522 to the radial through-hole 62c of the base 62, and cover the channel opening of the axial channel 62b (between the flared guide tube 63 and the pill inlet 61a); when the pills fall from the conveyor belt 73, the pills pass through the flared guide tube 63 and the axial channel 62b and fall on the oil paper, and the oil paper and the pills enter the pill inlet 61a together and descend along the spiral ball rolling channel 61c; during the descending process, the oil paper gradually completely wraps the pills, and the pills are further processed and formed until the finished pills fall from the discharge port 61b and enter the drawer-type receiving box 8.

[0087] When gauze is used to pack pills, the cloth feeding motor 552 is started, and the gauze head is inserted between the cloth feeding rollers 551. The cloth feeding rollers 551 clamp the gauze head and pull the gauze so that the gauze head passes through the second gauze entrance 562e and waits for the clamping plate 564 to clamp it; at the same time, the translation motor 562d is started, driving the horizontal movable seat 561 to move toward the left fixed seat 562a. When it reaches one side of the left fixed seat 562a, the steering gear 565a is started, driving the two clamping plates 564 to move toward each other and clamp the gauze head waiting there; after the clamping plate 564 clamps the gauze head, the motor shaft of the translation motor 562d rotates in the opposite direction, driving the horizontal movable seat 561 to translate in the opposite direction and move toward the right fixed seat 562b; when the horizontal movable seat 561 returns to its original position, the lifting motor 572b is started, driving the lifting movable seat 571 downward, and the cutter will be exposed on the left The gauze on the outside of the fixed seat 562a is cut off; at the same time, the steering gear 565a rotates in the opposite direction, driving the two clamping plates 564 to move back to each other, loosening the gauze head; the cut gauze head falls onto the flared guide tube 63 (the setting of the flared guide tube 63 is not only conducive to catching the pills, but also conducive to catching the gauze, avoiding the gauze from being too far away from the pill entrance 61a, causing the gauze to glide to the side of the pill entrance 61a and making it difficult to catch the pills); when the pills fall from the conveyor belt 73, the pills first fall on the gauze, and then the gauze and the pills enter the flared guide tube 63, the axial channel 62b and the pill entrance 61a together, and descend along the spiral ball rolling channel 61c; during the descending process, the gauze gradually completely wraps the pills, and the pills are further processed and formed until the finished pills fall from the discharge port 61b and enter the drawer-type material receiving box 8.

[0088] After using it for a period of time, the anti-sticking cleaning mechanism can be started to clean or lubricate the inner wall of the first ball rolling cylinder 41; at this time, the curved pipe 45 should be rotated in advance so that the opening of the curved pipe 45 faces away from the discharge end of the conveyor belt 73, and a receiving basin is set on the feed end side of the conveyor belt 73 to receive the liquid or stains flushed out of the first ball rolling cylinder 41.
