Description

Technical Field

[0001] This invention relates to the field of medicine bottle filling technology, and more specifically, to a multi-piece combined visual counting and filling device. Background Technology

[0002] In the field of pharmaceutical bottle filling, common filling equipment mainly includes a frame, a hopper mounted on the frame, rollers, and a granule rejection structure. The rollers are mounted on the frame via a rotating shaft. During the granule filling process, the granule opening on the rollers receives the granules from the hopper. After the granules reach the granule rejection structure, the granule rejection structure rejects the granules to achieve bottling.

[0003] However, currently, the rollers in common filling equipment are integral structures. When filling different types or specifications of medicines, the rollers and shafts need to be disassembled from the frame before the rollers can be replaced, which is inconvenient. Summary of the Invention

[0004] The problem this invention addresses is: how to improve the efficiency of roller disassembly in granule filling equipment.

[0005] To address the aforementioned problems, the present invention provides a multi-piece combined visual counting and filling device, comprising a connecting shaft mounted on a frame and multiple filling rollers fitted onto the connecting shaft. The connecting shaft includes a fixed shaft and a movable shaft connected sequentially along its axial direction. The movable shaft and the fixed shaft are detachably inserted into each other along the axial direction. When connected, the movable shaft and the fixed shaft are used to drive the multiple filling rollers to rotate synchronously. When separated, the movable shaft and the fixed shaft are used to disassemble the multiple filling rollers.

[0006] Optionally, the multi-piece combined visual counting and filling device further includes a motor and a through-type linear motor mounted on the frame. The through-type linear motor is driven connected to the end of the movable shaft away from the fixed shaft and is used to drive the movable shaft to move linearly away from or towards the fixed shaft. The motor is driven connected to the end of the fixed shaft away from the movable shaft and is used to drive the fixed shaft and the movable shaft to rotate synchronously.

[0007] Optionally, the multi-piece combined visual counting and filling device further includes a visual counting and imaging module installed on the frame. The probe of the visual counting and imaging module faces the pill holes on the peripheral sidewall of the filling roller to obtain the number of pills filled in the pill holes corresponding to the filling roller.

[0008] Optionally, the multi-piece combined visual counting and filling device further includes a granule channel and a dispensing needle located below and on one side of the axis of the granulation roller. The granule channel and the dispensing needle correspond one-to-one with the granulation roller. The granulation roller also includes an annular groove disposed on the circumferential sidewall of the granulation roller. The annular groove connects multiple granule holes along the circumferential direction of the granulation roller. The dispensing needle is located above the granule channel. One end of the dispensing needle is slidably connected to the corresponding annular groove, and the other end extends to the upper entrance of the corresponding granule channel and is connected to the end of the entrance near the granulation roller.

[0009] Optionally, the multi-piece combined visual counting and filling device further includes a through-beam photoelectric module, which is connected to the drug channel in a one-to-one correspondence, and emits light into the drug channel along the radial direction of the drug channel.

[0010] Optionally, the multi-piece combined visual counting and filling device further includes a bottle ejection mechanism located below the lower end outlet of the granule channel. The bottle ejection mechanism includes an ejection cylinder, a support block, a suction nozzle, and a spring. The driving end of the ejection cylinder is positioned facing the outlet and is drivenly connected to the support block. The spring is connected between the support block and the suction nozzle. The suction nozzle is used to communicate with an air source and to suck up the bottom of the bottle. The outlet is used to insert into the bottle mouth.

[0011] Optionally, the multi-piece combined visual counting and filling device further includes an upward-facing hopper. The hopper has an opening on a portion of its side wall near the bottom. The hopper is disposed on the outer peripheral wall of the multiple granulation rollers through the opening. An actuating wheel is provided inside the hopper. The actuating wheel is located near the lower edge of the opening and corresponds one-to-one with the positions of the multiple granulation rollers along the axial direction. The rotation direction of the actuating wheel is opposite to the rotation direction of the granulation rollers.

[0012] Optionally, the multi-piece combined visual counting and filling device further includes a roller brush, which is rotatably disposed inside the hopper and located above the granulation roller, and the rotation direction of the roller brush is the same as the rotation direction of the granulation roller.

[0013] Optionally, the movable shaft is mounted to the frame via a linear guide pair.

[0014] Optionally, the multi-piece combined visual counting and filling device further includes a baffle plate located above the dispensing needle, the baffle plate extending and curving along the outer peripheral wall of the filling roller and covering the outer peripheral wall of the filling roller.

[0015] Compared with related technologies, the multi-piece combined visual counting and filling device of the present invention, when the fixed shaft and the movable shaft are connected, can drive multiple filling rollers to rotate synchronously, and the multiple filling rollers can meet the production needs of filling medicine. When the fixed shaft and the movable shaft are separated, the fixed shaft and the movable shaft are disconnected, and the multiple filling rollers can be disassembled from the fixed shaft and the movable shaft, realizing the individual disassembly of each filling roller. This also allows for individual cleaning of each filling roller. In this way, when filling different types or different specifications of medicines, the filling rollers can be replaced individually for easy cleaning and disassembly. Attached Figure Description

Detailed Implementation

[0025] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0026] In the attached figures, the X-axis represents the horizontal position, with the positive direction of the X-axis indicating the right side and the negative direction indicating the left side; the Y-axis represents the front-to-back position, with the positive direction of the Y-axis indicating the front and the negative direction indicating the back; the Z-axis represents the vertical position, with the positive direction of the Z-axis indicating the top and the negative direction indicating the bottom.

[0027] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in sequences other than those illustrated or described herein.

[0028] Combination Figure 1 and Figure 2 As shown, this embodiment of the invention provides a multi-piece combined visual counting and filling device, including a connecting shaft mounted on a frame 1 and a multi-piece filling roller 4 fitted on the connecting shaft. The connecting shaft includes a fixed shaft 2 and a movable shaft 3 connected sequentially along its axial direction. The movable shaft 3 and the fixed shaft 2 are detachably inserted along the axial direction. When connected, the movable shaft 3 and the fixed shaft 2 are used to drive the multi-piece filling roller 4 to rotate synchronously. When separated, the movable shaft 3 and the fixed shaft 2 are used to disassemble the multi-piece filling roller 4.

[0029] Specifically, the fixed shaft 2 and the movable shaft 3 are coaxially arranged along the X-axis, with the fixed shaft 2 located at the right end of the frame 1 and the movable shaft 3 located at the left end of the frame 1, as shown below. Figure 1 As shown, multiple granulation rollers 4 are all mounted on a fixed shaft 2 and a movable shaft 3. The middle granulation roller 4 is splinedly connected to both the fixed shaft 2 and the movable shaft 3, serving as a connector to ensure that the fixed shaft 2 and the movable shaft 3 can rotate synchronously. Adjacent granulation rollers 4 are tightly fitted together. The synchronous rotation of the fixed shaft 2 and the movable shaft 3 can drive the multiple granulation rollers 4 to rotate synchronously. For example, the fixed shaft 2 and the movable shaft 3 can both be splined shafts, and the fixed shaft 2 and the movable shaft 3 are splinedly connected to the multiple granulation rollers 4 to drive them to rotate synchronously. When the multiple granulation rollers 4 rotate synchronously, each granulation roller 4 can hold a certain number of granules to meet the production needs of granule filling. Figure 2As shown, the movable shaft 3 can move axially to separate from the fixed shaft 2. That is, the movable shaft 3 moves axially away from the fixed shaft 2, causing the fixed shaft 2 and the movable shaft 3 to disconnect. After disconnection, there is a gap between the fixed shaft 2 and the movable shaft 3. The middle granulation roller 4 is detached from the movable shaft 3 and can be disassembled from the gap. Then, the remaining granulation rollers 4 on the fixed shaft 2 and the movable shaft 3 can be disassembled, thereby realizing the individual disassembly of the granulation roller 4 without having to remove the fixed shaft 2 and the movable shaft 3 as a whole from the frame 1 and then disassemble the granulation roller 4. This optimizes the disassembly and assembly of the granulation roller 4 and saves the disassembly and assembly time of the granulation roller 4.

[0030] Therefore, in this embodiment, when the fixed shaft 2 and the movable shaft 3 are connected, the fixed shaft 2 and the movable shaft 3 can drive the multiple granulation rollers 4 to rotate synchronously, and the multiple granulation rollers 4 can meet the production needs of granule filling. When the fixed shaft 2 and the movable shaft 3 are separated, the fixed shaft 2 and the movable shaft 3 are disconnected, and the multiple granulation rollers 4 can be disassembled from the fixed shaft 2 and the movable shaft 3, so that each granulation roller 4 can be disassembled individually, and each granulation roller 4 can be cleaned individually. In this way, when filling different types of medicines or different specifications of medicines, the granulation rollers 4 can be replaced individually for easy cleaning and disassembly.

[0031] Optionally, combined Figure 1 and Figure 2 As shown, the multi-piece combined visual counting and filling device also includes a motor 5 and a through-type linear motor 6 mounted on the frame 1. The through-type linear motor 6 is driven to the end of the movable shaft 3 away from the fixed shaft 2 and is used to drive the movable shaft 3 to move linearly away from or towards the fixed shaft 2. The motor 5 is driven to the end of the fixed shaft 2 away from the movable shaft 3 and is used to drive the fixed shaft 2 and the movable shaft 3 to rotate synchronously.

[0032] Specifically, the end of the fixed shaft 2 furthest from the movable shaft 3 is mounted on the frame 1 via a bearing seat, and the end of the movable shaft 3 furthest from the fixed shaft 2 is also mounted on the frame 1 via a bearing seat. The fixed shaft 2 and the movable shaft 3 can rotate around their own axes. The motor 5 is located on the side of the fixed shaft 2 furthest from the movable shaft 3 and is mounted on the frame 1. The drive end of the motor 5 is connected to the fixed shaft 2 via a coupling, or it can drive the fixed shaft 2 directly. A through-type linear motor 6 is located on the side of the movable shaft 3 furthest from the fixed shaft 2 and is mounted on the frame 1. The through-type linear motor 6 is connected to the movable shaft 3. During filling production, the through-type linear motor 6 stops, and the motor 5 starts, driving the fixed shaft 2 and the movable shaft 3 to rotate synchronously. When the granulation roller 4 is disassembled, the through-type linear motor 6 starts, the motor 5 stops, the fixed shaft 2 and the movable shaft 3 stop rotating synchronously, the through-type linear motor 6 drives the movable shaft 3 to move away from the fixed shaft 2, after the granulation roller 4 is assembled, the through-type linear motor 6 drives the movable shaft 3 to move towards the fixed shaft 2, so that the movable shaft 3 is connected to the fixed shaft 2.

[0033] Thus, by connecting the through-type linear motor 6 to the end of the movable shaft 3 furthest from the fixed shaft 2, and using it to drive the movable shaft 3 to move linearly away from or towards the fixed shaft 2, the through-type linear motor 6 can connect or disconnect the movable shaft 3 and the fixed shaft 2, thereby improving the switching efficiency between different states of the fixed shaft 2 and the movable shaft 3. Furthermore, by connecting the motor 5 to the end of the fixed shaft 2 furthest from the movable shaft 3, and using it to drive the fixed shaft 2 and the movable shaft 3 to rotate synchronously, the motor 5 achieves synchronous rotation of the fixed shaft 2 and the movable shaft 3 after connection, to meet the production requirements of granule filling.

[0034] Optionally, combined Figure 3 , Figure 5 and Figure 6 As shown, the multi-piece combined visual counting and filling device also includes a visual counting and imaging module 7 installed on the frame 1. The probe of the visual counting and imaging module 7 faces the pill holes 41 on the side wall of the filling roller 4 to obtain the number of pills filled in the corresponding pill holes 41 of the filling roller 4.

[0035] Specifically, the visual counting and photographing module 7 uses a line scan camera for image capture. The PLC controller provides the start signal for image capture, and images are taken during bottling. The length of the photographing area (corresponding to the number of pill holes 41) is precisely controlled by the PLC and encoder. When the camera acquires images, it divides the area corresponding to the pill holes 41 of each bottle and obtains the number of pills in the corresponding area of ​​each bottle. The camera automatically divides the current bottling portion and the next bottling portion according to the distance between the photographing point and the bottling drop point (removal needle 9). The next bottling portion refers to the pill area between the camera's photographing point and the drop point, i.e., the area where pills remain within the area covered by the baffle plate 14. After counting the number of each portion, the algorithm combines them to obtain the number of pills in the current bottling. Finally, the number of pills in each bottle is sent to the PLC controller via communication software. The PLC judges whether it is qualified and performs the next step of rejection.

[0036] For example, taking a bottle containing 30 pills as an example, assuming the baffle covers the area of ​​the 10 pills above the dispensing needle 9, the line scan camera selects a position 10 pills away from the top of the dispensing needle 9 (the upper edge of the baffle 14) as the shooting point. Each time, the PLC controls the filling roller 4 to rotate 30 pills' distance. The camera takes pictures of the pills within the moving distance and automatically segments the image in the height direction at a 20:10 ratio, obtaining the image of the current filling portion (the 20 pills inside the bottle) and the image of the next filling portion (the 10 pills inside the baffle 14). A threshold segmentation algorithm can be used to segment the pills in the two images, and the number of pills in each portion can be counted. Finally, the number of pills in the current filling portion is added to the number of pills in the next filling portion obtained from the previous image to obtain the total number of pills in the current filling.

[0037] Thus, by pointing the probe of the visual counting and imaging module 7 toward the pill hole 41 on the pill filling roller 4, the number of pills in the corresponding pill hole 41 of the pill filling roller 4 can be obtained. The probe of the visual counting and imaging module 7 can directly obtain the pill filling status of each pill hole 41, thereby realizing the feedback of the pill filling quantity before the pills are bottled, avoiding interference from pill fragments at the bottle mouth during bottling, and improving the accuracy of counting.

[0038] Optionally, combined Figures 3 to 6As shown, the multi-piece combined visual counting and filling device also includes a pill channel 8 and a dispensing needle 9 located below the axis of the filling roller 4 and on one side of the axis. The pill channel 8 and the dispensing needle 9 correspond one-to-one with the filling roller 4. The filling roller 4 also includes an annular groove 42 provided on the circumferential side wall of the filling roller 4. The annular groove 42 connects multiple pill holes 41 along the circumferential direction of the filling roller 4. The dispensing needle 9 is located above the pill channel 8. One end of the dispensing needle 9 is slidably connected to the corresponding annular groove 42, and the other end extends to the upper entrance of the corresponding pill channel 8 and is connected to the end of the entrance near the filling roller 4.

[0039] Specifically, such as Figure 5 and Figure 6 As shown, multiple drug orifices 41 are distributed circumferentially along the loading roller 4 to form a row of drug orifice groups. Each loading roller 4 has multiple rows of drug orifice groups, and one row of drug orifice groups corresponds to one drug channel 8, as shown. Figure 6 As shown, in the circumferential direction of the pelleting roller 4, the annular groove 42 connects multiple pellet holes 41, or in other words, the annular groove 42 penetrates all pellet holes 41 along the circumferential direction of the pelleting roller 4. The pellet channel 8 and the ejector needle 9 are both located below the axis of the pelleting roller 4, and the ejector needle 9 is located between the pellet channel 8 and the axis of the pelleting roller 4. The upper end of the granule channel 8 is the entrance of the granule channel 8. The upper end of the needle 9 extends into the annular groove 42, and the lower end of the needle 9 extends obliquely to the entrance of the granule channel 8 and is connected to the end of the entrance near the granulation roller 4. During the filling process, the upper end of the needle 9 is located in the annular groove 42 so that it can extend into the bottom of the granule hole 41 through the annular groove 42. As the granulation roller 4 rotates, the upper end of the needle 9 drives the granules in the granule hole 41 to detach from the granule hole 41. Under the action of gravity, the granules slide along the needle 9 into the entrance of the granule channel 8, and then fall into the mouth of the medicine bottle from the outlet of the granule channel 8.

[0040] Thus, the annular groove 42 of the granulation roller 4 connects the granule holes 41 along the circumference of the granulation roller 4, and the rejection needle 9 is located above the granule channel 8. One end of the rejection needle 9 is slidably connected to the annular groove 42, and the other end extends to the entrance of the granule channel 8 and is connected to the end of the entrance near the granulation roller 4. The rejection needle 9 realizes the transition connection between the granule holes 41 and the granule channel 8. The upper end of the rejection needle 9 can extend into the bottom of the granule holes 41 with the help of the annular groove 42, so that the granules in each granule hole 41 can slide along the rejection needle 9 into the entrance of the granule channel 8 with the help of the rotation of the granulation roller 4, thereby realizing the automatic rejection of granules. Then, through the granule channel 8 corresponding one-to-one with the granulation roller 4, the automatic rejection of granules on multiple granulation rollers 4 can be realized during the filling process, so as to improve the filling efficiency.

[0041] Based on the above embodiments, such as Figure 6As shown, each pelleting roller 4 also includes a drop guide groove 43, which corresponds to a row of pellet holes. The drop guide groove 43 extends circumferentially along the pelleting roller 4 and communicates with multiple pellet holes 41 in the corresponding pellet hole group. The cross-sectional shape of the drop guide groove 43 in its extending direction is arc-shaped, and the arc-shaped opening faces away from the axis of the pelleting roller 4. During pelleting, the opening shape of the drop guide groove 43 allows each pellet to fall smoothly into the corresponding pellet hole 41.

[0042] Optionally, combined Figure 4 As shown, the multi-piece combined visual counting and filling device also includes a through-beam photoelectric module 10, which is connected to the drug channel 8 in a one-to-one correspondence. The through-beam photoelectric module 10 emits light into the drug channel 8 along the radial direction of the drug channel 8.

[0043] Specifically, the through-beam photoelectric module 10 refers to a through-beam photoelectric sensor. When an object obstructs the propagation of light, it outputs a signal. The through-beam photoelectric module 10 can also communicate with a host computer. The bottom of the granule channel 8 is the outlet of the granule channel 8. One through-beam photoelectric module 10 corresponds to one granule channel 8. The through-beam photoelectric module 10 is set close to the bottom of the corresponding granule channel 8. The through-beam photoelectric module 10 emits light radially into the granule channel 8. During the filling process, when the granule obstructs the propagation of the light emitted by the through-beam photoelectric module 10, the through-beam photoelectric module 10 outputs a signal. This signal indicates that the granule channel 8 is not blocked. When the granule does not obstruct the propagation of the light emitted by the through-beam photoelectric module 10, the through-beam photoelectric module 10 does not output a signal, indicating that the granule channel 8 may be blocked and needs to be cleared in time to avoid affecting the filling production.

[0044] Thus, by having a one-to-one correspondence between the photoelectric module 10 and the granule channel 8, the photoelectric module 10 emits light radially into the granule channel 8. The output signal of the photoelectric module 10 can be used to feedback whether there is granule flowing out of the granule channel 8, to provide feedback on whether the granule has entered the medicine bottle, and to improve the accuracy of granule bottling detection. It can also form a dual feedback mechanism with the visual granule counting and imaging module 7 to improve the degree of automation in filling.

[0045] Optionally, combined Figure 4 As shown, the multi-piece combined visual counting and filling device also includes a bottle ejection mechanism 11 located below the lower end outlet of the pill channel 8. The bottle ejection mechanism 11 includes an ejection cylinder 111, a support block 112, a suction nozzle 113, and a spring 114. The driving end of the ejection cylinder 111 is set towards the outlet and is drivenly connected to the support block 112. The spring 114 is connected between the support block 112 and the suction nozzle 113. The suction nozzle 113 is used to communicate with the air source and to suck up the bottom of the bottle. The outlet is used to insert into the bottle mouth of the bottle.

[0046] Specifically, the drive end of the ejector cylinder 111 faces upward and is driven to connect with the support block 112. The suction nozzle 113 is located above the support block 112. The spring 114 connects between the support block 112 and the suction nozzle 113. The suction nozzle 113 is connected to the air source via an air pipe. During the granule filling process, the bottle conveying mechanism transports the bottle to the bottom of the granule channel 8, with the bottle mouth aligned with the outlet at the lower end of the granule channel 8. Then, the ejector cylinder 111 drives the support block 112 to move towards the bottom of the bottle so that the suction nozzle 113 can suck up the bottom of the bottle. After sucking up, under the action of the ejector cylinder 111, the bottle continues to move upward until the bottle mouth is inserted into the outlet of the granule channel 8, achieving the insertion of the bottle mouth into the granule channel 8. During this process, the spring 114... It can compensate for the height of the medicine bottle ejection. For example, when the height of the medicine bottles is different and the extension length of the ejection cylinder 111 is constant, the taller medicine bottle is inserted into the medicine channel 8 before the shorter medicine bottle. When the ejection cylinder 111 has not reached the constant extension length, as the ejection cylinder 111 continues to extend, the taller medicine bottle will compress the spring 114 to ensure that when the ejection cylinder 111 reaches the constant extension length, the shorter medicine bottle can also be inserted and positioned into the medicine channel 8.

[0047] Thus, by driving the ejector cylinder 111 towards the outlet and driving it to connect with the support block 112, the spring 114 is connected between the support block 112 and the suction nozzle 113. The suction nozzle 113 is used to communicate with the air source and to suck up the bottom of the bottle, and its outlet is used to insert into the bottle mouth. The suction nozzle 113 can stabilize the bottle body by lifting it up, and by lifting the bottle body, the bottle body can move towards the granule channel 8 to shorten the length of the granule channel 8, thereby reducing the existence time of the granules in the granule channel 8. This not only reduces the risk of the granules being damaged by the granule channel 8, but also reduces the risk of the granule channel 8 being blocked. During the filling process, the spring 114 can compensate for the height of the bottle body while keeping the extension length of the ejector cylinder 111 constant, so that bottle mouths of different heights can be inserted and positioned at the outlet of the corresponding granule channel 8, thereby improving filling efficiency.

[0048] Optionally, combined Figure 3 and Figure 7 As shown, the multi-piece combined visual counting and filling device also includes an upward-facing hopper 12. The side wall of the hopper 12 near the bottom is provided with an opening. The hopper 12 is mounted on the outer peripheral wall of the multiple granulation rollers 4 through the opening. A push wheel 121 is provided inside the hopper 12. The push wheel 121 is located near the lower edge of the opening and corresponds one-to-one with the position of the multiple granulation rollers 4 along the axial direction. The rotation direction of the push wheel 121 is opposite to the rotation direction of the granulation rollers 4.

[0049] Specifically, the hopper 12 has its opening facing upwards and is mounted on the frame 1. The side wall of the hopper 12 facing the granulation roller 4 is hollowed out; this hollowed-out area is the opening of the hopper 12. It also has a side that curves circumferentially along the granulation roller 4 so that the hopper 12 covers multiple granulation rollers 4. The hopper 12 can communicate with the multiple granulation rollers 4. A actuating wheel 121 is provided at the bottom of the hopper 12. The actuating wheel 121 is mounted on the hopper 12 and rotates around its own axis. For example, the actuating wheel 121 is an impeller, and it is driven to rotate by a drive motor. Figure 7 As shown, the rotation direction of the agitator wheel 121 is opposite to that of the granulation roller 4. During the rotation of the granulation roller 4, the granules at the bottom of the hopper 12 enter the granule holes 41 of the granulation roller 4 under the agitation of the agitator wheel 121. At the same time, by agitating the granules in the hopper 12, the agitator wheel 121 can alleviate the stagnation and reduced flowability of the granules caused by granule accumulation, thus ensuring that the granules can easily enter the corresponding granule holes 41. In addition, the agitator wheel 121 can block the granules in the hopper 12 to prevent multiple granules from appearing in the granule holes 41.

[0050] Thus, the hopper 12 is connected to the granulation roller 4 and covers the granulation roller 4. The bottom of the hopper 12 is provided with a rotary wheel 121. The rotation direction of the rotary wheel 121 is opposite to the rotation direction of the granulation roller 4. The granules in the hopper 12 are loaded only by the rotation of the rotary wheel 121 to ensure that the loading of the granules is orderly and controllable.

[0051] Optionally, combined Figure 7 As shown, the multi-piece combined visual counting and filling device also includes a roller brush 13, which is rotatably disposed inside the hopper 12 and located above the granulation roller 4. The rotation direction of the roller brush 13 is the same as the rotation direction of the granulation roller 4.

[0052] Specifically, the roller brush 13 is mounted on the hopper 12 and rotates around its own axis. It can be driven by a corresponding motor. The roller brush 13 is located above the granulation roller 4. When the granulation roller 4 rotates clockwise, the roller brush 13 rotates clockwise. The roller brush 13 can remove excess granules from the granule hole 41.

[0053] Thus, by rotating the roller brush 13 above the granulation roller 4 onto the hopper 12, and with the rotation direction of the roller brush 13 being the same as that of the granulation roller 4, the roller brush 13 can cooperate with the actuating wheel 121 to prevent multiple particles from entering the granule hole 41, thereby improving the reliability of granule filling.

[0054] Optionally, combined Figure 3 As shown, the movable shaft 3 is mounted on the frame 1 via a linear guide pair.

[0055] Specifically, the linear guide pair includes a sliding block and a guide rail with a sliding fit. The guide rail extends axially along the movable shaft 3 and is mounted on the frame 1. The movable shaft 3 is mounted on the slider through a bearing seat so that the movable shaft 3 can rotate relative to the slider. When the movable shaft 3 moves away from the fixed shaft 2, the slider slides along the guide rail.

[0056] Thus, the movable shaft 3 is mounted on the frame 1 via a linear guide pair, which supports the movable shaft 3 and ensures the moving accuracy of the movable shaft 3.

[0057] Optionally, combined Figure 3 As shown, the multi-piece combined visual counting and filling device also includes a baffle plate 14, which is located above the dispensing needle 9. The baffle plate 14 extends and bends along the outer peripheral wall of the filling roller 4 and covers the outer peripheral wall of the filling roller 4.

[0058] Specifically, the baffle plate 14 is bent along the rotation direction of the pelleting roller 4, that is, the baffle plate 14 is arc-shaped. The baffle plate 14 is mounted on the frame 1 and is located above the dispensing needle 9. During the rotation of the pelleting roller 4, the baffle plate 14 can prevent the pellets in the pellet hole 41 from falling out, thereby ensuring that the pellets can only be removed from the pellet hole 41 by the dispensing needle 9.

[0059] Thus, by bending and extending along the outer peripheral wall of the granulation roller 4 and covering the outer peripheral wall of the granulation roller 4, the baffle plate 14 can block the granules in the granule hole 41, ensuring that the granules can only leave the granule hole 41 by being removed by the baffle plate 9, thereby ensuring the accuracy of the granule filling quantity.

[0060] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
