DETAILED DESCRIPTION

[0035] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively with reference to the accompanying drawings. The accompanying drawings show preferred embodiments of the present invention.

[0036] like Figures 1 to 7 As shown, a powder filling mechanism 10 includes a machine 100 and a filling assembly 200, the filling assembly 200 includes a material tray 210, a bottom ring 220, a filling rod 230 and a push rod 240, the material tray 210 is rotatably arranged on the machine 100, a filling hole 211 is opened in the material tray 210, the bottom ring 220 is arranged on the machine 100 with an adjustable height, and the bottom ring 220 is located at the bottom side of the material tray 210, so that the distance between the bottom ring 220 and the material tray 210 is adjustable, and an air avoidance groove 221 is opened on the bottom ring 220, and the filling rod 230 and the push rod 240 are both slidably arranged on the machine 100 along the vertical direction. , and the filling rod 230 and the pushing rod 240 are both located above the material tray 210, and the pushing rod 240 is aligned with the air avoidance groove 221, and the filling rod 230 is aligned with the bottom ring 220, and the material tray 210 is used to rotate so that the filling hole 211 circulates through the filling rod 230 and the pushing rod 240, when the filling hole 211 is aligned with the filling rod 230 and the filling rod 230 is lowered, so that the filling rod 230 presses the powder into the filling hole 211, when the filling hole 211 is aligned with the pushing rod 240 and the pushing rod 240 is lowered, so that the pushing rod 240 pushes the compacted powder in the filling hole 211 out of the air avoidance groove 221.

[0037] It should be noted that the material tray 210 can be driven by a driving source such as a motor to rotate on the machine 100. A filling hole 211 with a penetrating structure is provided on the inner bottom wall of the material tray 210. The material tray 210 is used to contain medicinal powder. In one embodiment, the material tray 210 includes a material plate and a ring surrounding the material plate, wherein the ring can be welded to the material plate or fixed to the material plate by bolts. The filling hole 211 is on the material plate. Furthermore, the bottom ring 220 is a circular ring structure, and the bottom ring 220 is height-adjustably mounted on the machine 100, and the bottom ring 220 is located below the material tray 210. In this way, by adjusting the height of the bottom ring 220 relative to the machine 100, the distance between the bottom ring 220 and the bottom surface of the material tray 210 can be adjusted. The bottom ring 220 is provided with an air avoidance groove 221, so that when the material tray 210 rotates, the filling hole 211 of the material tray 210 will cyclically pass through the air avoidance groove 221. When the filling hole 211 does not pass through the air avoidance groove 221, the filling hole 211 is aligned with the bottom ring 220. By adjusting the distance between the bottom ring 220 and the bottom surface of the material tray 210, it is equivalent to using the bottom ring 220 to seal the lower end of the filling hole 211. When the filling hole 211 passes through the air avoidance groove 221, it is equivalent to the lower end of the filling hole 211 is opened. Further, the filling rod 230 and the push rod 240 are both slidably installed on the machine 100 along the vertical direction, and the filling rod 230 and the push rod 240 can be lifted and slid relative to the machine 100. For example, the filling rod 230 and the push rod 240 can be driven by a screw module driven by a motor to lift and move. Further, the filling rod 230 and the push rod 240 can be lifted and moved synchronously or asynchronously. The push rod 240 is located above the avoidance groove 221, and the filling rod 230 is located above the bottom ring 220. When the material tray 210 rotates relative to the machine 100, the filling hole 211 of the material tray 210 cyclically passes through the filling rod 230 and the push rod 240. When the filling rod 230 and the push rod 240 move up and down asynchronously, the number of the filling hole 211 can be at least one, and when the filling rod 230 and the push rod 240 move up and down synchronously, the number of the filling holes 211 is equal to the sum of the number of the filling rod 230 and the push rod 240. In this way, when the material tray 210 rotates, the filling hole 211 is aligned with the filling rod 230. At this time, the lower end of the filling hole 211 is blocked by the bottom ring 220, which is equivalent to a closed mouth. As the filling rod 230 descends, the filling rod 230 will compact the medicine powder contained in the material tray 210 into the filling hole 211, and then the filling rod 230 rises and resets. When the material tray 210 rotates so that the filling hole 211 is aligned with the pushing rod 240, the filling hole 211 is aligned with the air avoidance groove 221, which is equivalent to the lower end of the filling hole 211 being opened. As the pushing rod 240 descends, the pushing rod 240 will push the compacted powder in the filling hole 211 out of the air avoidance groove 221 below.In this way, by utilizing the filling rod 230 and the pushing rod 240 in cooperation with the filling hole 211, the powder can be quantitatively compacted in the filling hole 211. The empty capsule only needs to be transferred to the air avoidance groove 221 and docked with the filling hole 211 to deliver a certain amount of powder into the capsule, thereby achieving quantitative and stable filling.

[0038] like Figures 1 to 4 As shown, in one embodiment, the filling assembly 200 further includes a rotating driving member 250, which is disposed on the machine platform 100, and the output shaft of the rotating driving member 250 passes through the bottom ring 220, and the material tray 210 is disposed on the output shaft of the rotating driving member 250. It should be noted that the rotating driving member 250 can be a cam divider, so that the cam divider can drive the material tray 210 to cyclically rotate at a certain angle and frequency, so that the filling hole 211 on the material tray 210 can cyclically pass through the filling rod 230 and the pushing rod 240.

[0039] like Figures 1 to 4 As described, in one embodiment, the filling assembly 200 further includes a storage seat 260 , which is disposed on the machine 100 , the output shaft of the rotating driving member 250 passes through the storage seat 260 , and the bottom ring 220 and the material tray 210 are both located in the storage seat 260 .

[0040] It should be noted that, since the material tray 210 needs to rotate relative to the bottom ring 220, there must be a certain gap between the bottom surface of the material tray 210 and the bottom ring 220. When the filling rod 230 compacts the medicine powder in the filling hole 211, the medicine powder will inevitably flow out of the filling hole 211 and fall into the gap between the bottom surface of the material tray 210 and the bottom ring 220, that is, fall on the bottom ring 220. In order to avoid the waste of these medicine powders, a storage seat 260 is installed on the machine 100. The output shaft of the rotary drive member 250 passes through the storage seat 260, so that the bottom ring 220 and the material tray 210 are both located in the storage seat 260. In this way, the medicine powder remaining on the bottom ring 220 can fall on the storage seat 260 and be stored.

[0041] like Figure 3 In one embodiment, an inclined inner wall 261 is provided in the storage seat 260, which is inclined from the periphery to the center. In this way, the interior of the storage seat 260 is similar to a funnel, and the outflowing medicine powder will flow into the middle position of the storage seat 260 near the rotating drive member 250 for easy storage.

[0042] like Figure 3 As shown, in one embodiment, a discharge hole 262 is further provided in the storage seat 260. It should be noted that in order to facilitate the discharge of the medicine powder stored in the storage seat 260, a discharge hole 262 is provided on one side of the storage seat 260, so that the medicine powder can be discharged from the discharge hole 262.

[0043] like Figure 1 As shown, in one embodiment, the filling assembly 200 also includes a scraper plate 271, which is disposed on the output shaft of the rotating drive member 250, and the scraper plate 271 is located in the storage seat 260. The rotating drive member 250 is used to drive the scraper plate 271 to circulate through the discharge hole 262.

[0044] It should be noted that the scraper plate 271 is mounted on the outer side wall of the rotary drive member 250, and the scraper plate 271 is close to the inner bottom wall of the storage seat 260. In this way, as the rotary drive member 250 drives the material tray 210 to rotate, it also drives the scraper plate 271 to rotate in the storage seat 260, thereby sending the medicine powder stored in the storage seat 260 out of the discharge hole 262. In this way, the medicine powder in the storage seat 260 can be stored by simply placing a container outside the storage seat 260 so that the container is aligned with the discharge hole 262.

[0045] like Figure 3 As shown, in one embodiment, the top surface of the storage seat 260 is higher than the bottom surface of the material tray 210. Thus, when the medicine powder is discharged from the lower port of the filling hole 211, that is, when the medicine powder is discharged from the gap between the material tray 210 and the bottom ring 220, since the top surface of the storage seat 260 is higher than the bottom surface of the material tray 210, the medicine powder can only fall into the storage seat 260 and will not fly out of the storage seat 260, thereby further preventing the medicine powder from splashing.

[0046] like Figure 3 and Figure 4 As shown, in one embodiment, a plurality of avoidance grooves are provided on the top surface of the storage seat 260, each avoidance groove is aligned with the bottom surface of the material tray 210, and the filling assembly 200 further includes a plurality of stoppers 272, each stopper 272 being detachably plugged into each avoidance groove.

[0047] It should be noted that the rotating drive member 250 drives the material tray 210 to rotate, and the height of the material tray 210 does not change. The storage seat 260 is also installed on the machine 100, and the height of the storage seat 260 does not change, and the top surface of the storage seat 260 is higher than the bottom surface of the material tray 210. The height of the bottom ring 220 is adjustable, that is, the distance between the bottom ring 220 and the bottom surface of the material tray 210 is adjustable. In order to facilitate the user to measure the distance between the bottom ring 220 and the bottom surface of the material tray 210, a plurality of avoidance grooves are provided on the top surface of the storage seat 260, and a stopper 272 is detachably installed in each avoidance groove. For example, the stopper 272 is installed on the storage seat 260 by bolts. In this way, after the stopper 272 is removed from the storage seat 260, the avoidance groove is aligned with the bottom surface of the material tray 210, and the distance between the bottom ring 220 and the bottom surface of the material tray 210 can be conveniently measured and adjusted using a thickness gauge. After the distance adjustment is completed, the stopper 272 can be reinstalled and fixed on the receiving seat 260 .

[0048] like Figure 6 As shown, in one embodiment, a scraper 273 is disposed on the bottom ring 220 , and the scraper 273 is disposed toward the bottom surface of the material tray 210 , and the scraper 273 is used to scrape off the medicine powder adhered to the bottom surface of the material tray 210 .

[0049] It should be noted that, since the distance between the bottom ring 220 and the bottom surface of the material tray 210 is relatively small, the distance ranges from 0.1 mm to 2 mm. The medicine powder inevitably enters the gap between the bottom ring 220 and the bottom surface of the material tray 210, so the bottom surface of the material tray 210 will adhere to the medicine powder. By installing a scraper 273 on the bottom ring 220, the medicine powder on the bottom surface of the material tray 210 can be scraped off. The scraper 273 is installed on the bottom ring 220 by screws, so the height of the scraper 273 relative to the bottom ring 220 is adjustable.

[0050] like Figure 6 As shown, in one embodiment, a scraper block 275 is further provided on the bottom ring 220 near the air-avoiding groove 221 , so that the scraper block 275 can be used to scrape the powder adhered to the bottom surface of the material tray 210 from the air-avoiding groove 221 .

[0051] Furthermore, if Figure 3 As shown, in one embodiment, chamfered portions 222 are provided on both the inner and outer walls of the bottom ring 220. Thus, the chamfered portions 222 are provided in an inclined state, which can prevent the medicine powder from being retained on the bottom ring 220, especially when the scraper 273 scrapes the medicine powder on the bottom surface of the material tray 210, the medicine powder will fall from the bottom ring 220 into the storage seat 260.

[0052] like Figures 1 to 4 As shown, in one embodiment, the filling assembly 200 also includes a plurality of adjusting members 280, each of which is penetrated by a receiving seat 260, and each of which is respectively connected to the machine 100 and the bottom ring 220, and the adjusting member 280 includes a slide column 281 and a supporting screw 282, and a plug hole 223 is provided on the bottom surface of the bottom ring 220, the slide column 281 is penetrated by the receiving seat 260 along the vertical direction, and the top end of the slide column 281 is inserted into the plug hole 223, the supporting screw 282 is screwed to the bottom end of the slide column 281, and the end of the supporting screw 282 away from the slide column 281 abuts against the machine 100.

[0053] It should be noted that the adjusting member 280 is used to adjust the height of the bottom ring 220. Specifically, the slide post 281 passes through the storage seat 260. It should be noted that the slide post 281 can only move up and down relative to the storage seat 260 in the vertical direction, and will not rotate relative to the storage seat 260. A plug hole 223 is provided on the bottom surface of the bottom ring 220, so that the local structure at the top of the slide post 281 is inserted into the plug hole 223. In this way, the bottom ring 220 is supported by each slide post 281. Further, the top holding screw 282 is coaxially screwed with the bottom end of the slide post 281, and the top holding screw 282 is in contact with the machine 100. In this way, by rotating the top holding screw 282, the slide post 281 can be moved up and down relative to the machine 100, or relative to the storage seat 260. In this way, the height position of the bottom ring 220 can be adjusted, that is, the distance between the bottom ring 220 and the bottom surface of the tray 210 can be adjusted.

[0054] like Figure 3 and Figure 8 As shown, in one embodiment, the slide column 281 is a cylindrical structure, and a guide groove 2811 is opened axially on the outer wall of the slide column 281. The adjustment member 280 also includes a limiting screw 283, which is screwed on the outer wall of the storage seat 260, and one end of the limiting screw 283 is adaptively accommodated in the guide groove 2811.

[0055] It should be noted that, since it is necessary to ensure that the slide post 281 can be lifted and lowered relative to the storage seat 260 in the vertical direction, in one embodiment, the slide post 281 can be set as a multi-faceted column structure, and a multi-sided hole is correspondingly opened on the storage seat 260, so that the slide post 281 fits through the multi-sided hole, and the slide post 281 can be lifted and lowered relative to the storage seat 260. Furthermore, in one embodiment, the slide post 281 can also be set as a cylindrical structure. In this way, a round hole is correspondingly opened on the storage seat 260, and compared with a multi-sided hole, a round hole is easier to process. In order to limit the sliding column 281 to slide only in the vertical direction and not rotate relative to the storage seat 260, a guide groove 2811 is opened axially on the outer wall of the sliding column 281, and then the limiting stud 283 is screwed to the outer wall of the storage seat 260, and one end of the limiting stud 283 is extended into the guide groove 2811 to limit the sliding column 281, so that the sliding column 281 can only be lifted and slid relative to the storage seat 260 in the vertical direction.

[0056] like Figure 8 As shown, in one embodiment, the adjustment member 280 further includes a locking nut 284 , which is threaded onto the supporting screw 282 , and the locking nut 284 is used to abut against the sliding column 281 to fix the supporting screw 282 and the sliding column 281 .

[0057] It should be noted that, after the height of the bottom ring 220 is adjusted, the slide post 281 is tightened by the locking nut 284 to ensure that the slide post 281 and the supporting screw 282 are locked and fixed as a whole.

[0058] like Figure 3 As shown, in one embodiment, a sealing ring 274 is disposed in the storage seat 260 , and the output shaft of the rotary driving member 250 passes through the sealing ring 274 .

[0059] It should be noted that in order to eliminate the gap between the storage seat 260 and the rotating drive member 250 , a sealing ring 274 is installed on the storage seat 260 to prevent the powder in the storage seat 260 from flowing out from the gap between the output shaft of the rotating drive member 250 and the storage seat 260 .

[0060] like Figures 1 to 3 , Figure 5 and Fig. 9 As shown, in one embodiment, the filling component 200 also includes a transverse plate 291 and a stop block 292. The transverse plate 291 is arranged on the machine 100, and the transverse plate 291 is located above the material tray 210, so that the push rod 240 and the filling rod 230 are both passed through the transverse plate 291. The stop block 292 is height-adjustably arranged on the transverse plate 291, and the stop block 292 is located in the material tray 210, so that the distance between the outer bottom wall of the stop block 292 and the inner bottom wall of the material tray 210 is adjustable, and the stop block 292 is aligned with the air avoidance groove 221, and a through hole 2921 is opened on the stop block 292, and the push rod 240 passes through the through hole 2921.

[0061] It should be noted that the transverse plate 291 is installed horizontally on the machine 100, and the transverse plate 291 is located above the material tray 210, which is equivalent to the transverse plate 291 covering the top of the material tray 210. In order not to affect the feeding of the powder into the material tray 210, a through hole for feeding is provided on the transverse plate 291. Further, the height of the blocking block 292 is adjustable on the bottom surface of the transverse plate 291, so that the blocking block 292 is located in the material tray 210, so that the distance between the outer bottom surface of the blocking block 292 and the inner bottom wall of the material tray 210 is adjustable. Further, a through hole 2921 is provided on the blocking block 292, so that the push rod 240 passes through the through hole 2921. Because the push rod 240 is used to push the powder in the filling hole 211 out of the air avoidance groove 221. When the push rod 240 rises, the powder in the tray 210 will enter the filling hole 211. At this time, the powder in the filling hole 211 is in a naturally loose state, so the powder will flow out of the filling hole 211. In order to avoid this problem, a blocking block 292 is installed on the horizontal plate 291, so that the blocking block 292 blocks the filling hole 211 located below. When the push rod 240 withdraws the powder in the filling hole 211 and rises to reset, the powder will not fall from the filling hole 211 at the corresponding position of the air-avoiding groove 221 because the blocking block 292 blocks the powder in the tray 210.

[0062] like Fig. 9 As shown, in one embodiment, a step groove 2922 is opened on the outer bottom wall of the blocking block 292 , and the through hole 2921 is located in the step groove 2922 . The direction of the opening E of the step groove 2922 is the same as the rotation direction of the material tray 210 .

[0063] It should be noted that when the push rod 240 enters the filling hole 211 to push out the compacted powder, some of the powder will inevitably overflow from the upper end of the filling hole 211, and the distance between the blocking block 292 and the inner bottom wall of the material tray 210 is very small. In order to prevent the overflowing powder from being squeezed between the blocking block 292 and the inner bottom wall of the material tray 210, a step groove 2922 is provided on one end surface of the blocking block 292 close to the inner bottom wall of the material tray 210. The gap is very small, which is equivalent to the step groove 2922 being sealed by the inner bottom wall of the material tray 210, and the height of the overflowed medicine powder must be greater than the gap between the blocking block 292 and the inner bottom wall of the material tray 210. When the material tray 210 continues to rotate, in order to prevent the overflowed medicine powder from blocking the blocking block 292 and entering the gap between the blocking block 292 and the inner bottom wall of the material tray 210, the step groove 2922 is set to a single-end non-closed structure. Specifically, the opening direction of the step groove 2922 is consistent with the rotation direction of the material tray 210. In this way, when the medicine powder overflows the inner bottom wall of the material tray 210, as the material tray 210 continues to rotate, the overflowed medicine powder will re-mix with other medicine powders in the material tray 210 blocked by the blocking block 292 along the opening of the step groove 2922.

[0064] like Fig. 9 As shown, in one embodiment, a slanted top surface 2923 is provided on one side of the blocking block 292 away from the opening direction of the step groove 2922 , and the material tray 210 is used to drive the medicine powder to approach the blocking block 292 so that the slanted top surface 2923 pushes the medicine powder toward the center of the material tray 210 .

[0065] It should be noted that the filling hole 211 is located at the edge of the inner bottom wall of the material tray 210, so the material stopper 292 is also located at the edge of the inner bottom wall of the material tray 210. When the material tray 210 rotates to drive the medicine powder to approach the material stopper 292, in order to prevent the medicine powder from entering the position between the material stopper 292 and the inner side wall of the material tray 210, an inclined top surface 2923 is provided on the side of the material stopper 292 away from the opening of the step groove 2922, and the inclined top surface 2923 is inclined toward the rotation center of the material tray 210, so that when the medicine powder contacts the material stopper 292, it will be pushed by the inclined top surface 2923 to approach the rotation axis of the material tray 210.

[0066] like Fig. 9 As shown, in one embodiment, two vertical rods 293 are further provided on the blocking block 292, and both vertical rods 293 pass through the horizontal plate 291. Each vertical rod 293 is located on the top surface and the side surface of the horizontal plate 291 and is respectively screwed with an adjusting nut 294, and the adjusting nut 294 is in contact with the horizontal plate 291.

[0067] Thus, when the adjusting nut 294 is rotated relative to the vertical rod 293, the adjusting nut 294 will slide along the axial direction of the vertical rod 293. Thus, the height of the stopper 292 can be adjusted. The two adjusting nuts 294 on the same vertical rod 293 are used to clamp the horizontal plate 291 together, so that the stopper 292 is reliably fixed.

[0068] like Figure 3 and Fig. 9 As shown, in one embodiment, a scraper 295 is disposed on the bottom surface of the transverse plate 291, and the scraper 295 is used to scrape the medicine powder.

[0069] It should be noted that, for example, the scraper 295 is a mesh structure, and when the material tray 210 drives the medicine powder to rotate, the scraper 295 can stir the medicine powder to keep the medicine powder loose and avoid agglomeration.

[0070] like Figure 3 and Fig. 9 As shown, in one embodiment, a powder blocking plate 296 is further provided on the bottom surface of the horizontal plate 291 .

[0071] It should be noted that a powder quantity detector is also installed on the transverse plate 291. In order to prevent the accumulation of powder when filling the material tray 210 and affecting the powder quantity detector, a powder blocking plate 296 is installed on the transverse plate 291 to block the powder.

[0072] like Figure 1 As shown, in one embodiment, the filling assembly 200 further includes a lifting frame 2100 , which is slidably disposed on the machine platform 100 along a vertical direction, the push rod 240 is disposed on the lifting frame 2100 , and the filling rod 230 is adjustably disposed on the lifting frame 2100 .

[0073] It should be noted that the filling rod 230 and the pushing rod 240 are both located on the lifting frame 2100 , and the lifting frame 2100 drives the filling rod 230 and the pushing rod 240 to move up and down synchronously.

[0074] like Figure 1 , Figure 3 and Fig.10 As shown, in one embodiment, the filling assembly 200 also includes a pushing block 2210, a locking screw 2220, a limiting cylinder 2230 and two first guide rods 2240. The two first guide rods 2240 are both arranged on the lifting frame 2100, and the two first guide rods 2240 are both penetrated by the pushing block 2210. The locking screw 2220 is sequentially penetrated by the pushing block 2210 and the limiting cylinder 2230 to be screwed to the lifting frame 2100, and the pushing rod 240 is arranged on the pushing block 2210.

[0075] It should be noted that the two first guide rods 2240 are fixedly mounted on the lifting frame 2100 along the vertical direction, and the two first guide rods 2240 both pass through the pusher block 2210, so that the pusher block 2210 can slide along the first guide rods 2240. One end of the pusher rod 240 is fixedly mounted on the pusher block 2210, and the other end of the pusher rod 240 passes through the lifting frame 2100 and then through the cross plate 291, and the locking screw 2220 passes through the pusher block 2210 and the limiting cylinder 2230 in sequence, and then is screwed and fixed on the lifting frame 2100. In this way, the limiting cylinder 2230 is used to limit the pusher block 2210, so that the lifting frame 2100 can stably drive the pusher rod 240 to push the compacted medicine powder in the filling hole 211 out of the air avoidance groove 221.

[0076] like Fig.10 and Fig.11As shown, in one embodiment, the filling component 200 also includes a filling screw 2310, a filling block 2320, a filling spring 2330 and two second guide rods 2340, the two second guide rods 2340 are both arranged on the lifting frame 2100, and the two second guide rods 2340 are both penetrated by the filling block 2320, the filling screw 2310 is rotatably arranged on the lifting frame 2100, and the filling screw 2310 is screwed with the filling block 2320, the filling rod 230 is slidably arranged on the filling block 2320, the filling spring 2330 is respectively in contact with the filling rod 230 and the filling block 2320, and the filling spring 2330 is used to push the filling rod 230 so that the filling rod 230 has a tendency to approach the material tray 210.

[0077] It should be noted that the two second guide rods 2340 are fixedly installed on the lifting frame 2100 along the vertical direction, and the two second guide rods 2340 both pass through the filler block 2320, so that the filler block 2320 can slide along the second guide rods 2340. The filler screw 2310 is rotatably connected relative to the lifting frame 2100, and the filler screw 2310 is screwed with the filler block 2320. In this way, by rotating the filler screw 2310, the sliding distance of the filler block 2320 on the second guide rod 2340 can be adjusted. Further, one end of the filler rod 230 is slidably installed in the filler block 2320, and the filler spring 2330 is respectively in contact with the filler block 2320 and the filler rod 230. Under the elastic thrust of the filler spring 2330, the filler rod 230 has a downward trend. In this way, when the lifting frame 2100 drives the filling block 2320 to descend, the filling rod 230 descends to compact the medicine powder in the filling hole 211. Since the filling spring 2330 is elastic, the filling rod 230 does not rigidly press the medicine powder in the filling hole 211, but applies a certain pressure to the medicine powder through the filling spring 2330. In this way, the compacted amount of the medicine powder in the filling hole 211 can be accurately controlled.

[0078] like Figure 2 , Fig.10 and Fig.11 As shown, in one embodiment, a plurality of filling rods 230 are provided on the filling block 2320, and a plurality of filling holes 211 are opened in the material tray 210. When the lifting frame 2100 drives each filling rod 230 to descend, each filling rod 230 is respectively penetrated by a filling hole 211.

[0079] In this way, a single filling block 2320 can simultaneously drive multiple filling rods 230 to move up and down. For example, each filling rod 230 is arranged along a straight line, and a plurality of filling holes 211 are correspondingly opened on the material tray 210, so that the amount of powder for a single capsule can be compacted in each filling hole 211. Therefore, multiple capsules can be filled at the same time to improve the powder filling efficiency of the capsules.

[0080] like Fig.10As shown, in one embodiment, a plurality of filler blocks 2320 are provided, and a plurality of filler rods 230 are provided on each filler block 2320 , and each filler rod 230 abuts against a filler spring 2330 .

[0081] It should be noted that there are multiple packing blocks 2320, and each packing block 2320 is provided with two second guide rods 2340 for guiding and sliding. Correspondingly, there are also multiple packing screws 2310, and each packing screw 2310 is rotatably connected to the lifting frame 2100, and each packing screw 2310 is respectively screwed to each packing block 2320. Each packing block 2320 is circumferentially distributed relative to the material tray 210. In this way, by adjusting the heights of the respective packing blocks 2320 by the respective packing screws 2310, that is, starting from the pushing block 2210 as the starting position and in the rotational direction of the material tray 210 as the gradual change sequence, the heights of the respective packing blocks 2320 increase, so that the amounts of medicine pressed into the packing holes 211 by the respective packing blocks 2320 are approximately the same. For the convenience of description, an example is described with the number of packing blocks 2320 being 5 and the material tray 210 rotating clockwise. The pushing block 2210 and the 5 packing blocks 2320 are circumferentially and equiangularly spaced relative to the material tray 210. Taking the position where the pushing block 2210 is located as the S0 station, and then in the clockwise direction, the five packing blocks 2320 are sequentially numbered as S1, S2, S3, S4, and S5 stations. Among them, in the S1 station, the packing screw 2310 at this station is adjusted to adjust the height of the packing block 2320 at this station, so that when the lifting frame 2100 drives the packing rod 230 at this station to descend to the lowest position, the distance between the bottom end of the packing rod 230 at this station and the bottom surface of the material tray 210 is S11; in the S2 station, the packing screw 2310 at this station is adjusted to adjust the height of the packing block 2320 at this station, so that when the lifting frame 2100 drives the packing rod 230 at this station to descend to the lowest position, the distance between the bottom end of the packing rod 230 at this station and the bottom surface of the material tray 210 is S21; and so on, so that the minimum distances between the bottom ends of the packing rods 230 in the S1 station, S2 station, S3 station, S4 station, and S5 station and the bottom surface of the material tray 210 are S11, S21, S31, S41, and S51 in sequence, where S11 < S21 < S31 < S41 < S51, and S51 is not greater than the depth of the packing hole 211. In this way, by adjusting the packing screws 2310 at each station, the insertion depth of each station into the packing hole 211 can be adjusted, which means that the amount of medicine powder pressed into the packing hole 211 by the packing rod 230 at each station can be adjusted. Finally, the pushing rod 240 located at the S0 station can penetrate the packing hole 211, and the medicine powder in the packing hole 211 can be pushed out from the clearance groove 221. To sum up, multiple quantitative fillings of a single capsule can be realized, effectively improving the accuracy of the amount of medicine powder filled in a single capsule.It should be noted that, in this embodiment, the filling blocks 2320 are 5, and the tray 210 rotates clockwise for explanation only for the convenience of understanding the technical effect brought about by setting the filling blocks 2320 to be multiple, and the height adjustment of the filling rod 230 in each filling block 2320 is different, and it should not be understood as limiting the number of filling blocks 2320 and the rotation direction of the tray 210. It is understandable that the filling blocks 2320 can also be set to any number value, such as 2, or 3, or 4, or 5, or 6, etc., because the working principle does not differ significantly due to different numbers, so the embodiments of other multiple numbers are not repeated. The tray 210 can also rotate clockwise or counterclockwise. In this way, the filling blocks 2320 are set to be multiple, and each filling block 2320 is provided with a filling rod 230, so as to achieve multiple quantitative filling of a single capsule, which can effectively improve the accuracy of the filling amount of the single capsule powder.

[0082] like Figure 1 As shown, in one embodiment, the lifting frame 2100 includes a lifting seat 2110, a connecting plate 2120 and two lifting columns 2130, the two lifting columns 2130 are respectively penetrated through the machine 100, the two ends of the connecting plate 2120 are respectively connected to the bottom ends of the two lifting columns 2130, the two ends of the lifting seat 2110 are respectively connected to the top ends of the two lifting columns 2130, and the pushing rod 240 and the filling rod 230 are both located on the lifting seat 2110.

[0083] In this way, applying a lifting thrust to the connecting plate 2120 can drive the lifting seat 2110 to move up and down. In this way, the connecting plate 2120 can be connected to the cam, and the cam and the rotating drive member 250 can be driven to rotate by the same motor. In this way, the same power source can be used to simultaneously drive the lifting frame 2100 to move up and down and drive the material tray 210 to rotate.

[0084] Furthermore, if Figure 1 As shown, in one embodiment, two pillars 110 are disposed on the machine 100, two lifting columns 2130 pass through the two pillars 110 respectively, and two ends of the horizontal plate 291 are respectively disposed on the top of the two pillars 110. In this way, the lifting frame 2100 and the horizontal plate 291 can share two pillars 110. Furthermore, in one embodiment, the lifting frame 2100 and the horizontal plate 291 can also be supported by two independent supporting structures.

[0085] like Figure 3 and Figure 5As shown, in one embodiment, a plurality of windows 2111 are further provided on the lifting seat 2110, and a scale 2140 is provided in each window 2111, and the scale 2140 is provided adjacent to the filling block 2320. For example, the window 2111 is a transparent plate structure, and the user can observe the filling block 2320 during the adjustment process through the window 2111 to compare with the scale 2140, so as to facilitate the precise adjustment of the filling rod 230.

[0086] The above-described embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the invention patent. The installation / fixing / setting mentioned in the present invention, unless otherwise specifically defined, may be understood to include but not be limited to locking and fixing with screws / screws, and welding. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements may be made without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention.
