For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.
[0031] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions, and cannot be understood as indicating or implying relative importance.
[0032] Embodiment, refer to Figure 1 , Figure 2 and Figure 3, which is an embodiment of the present utility model, proposes a multi-stage clamp-type dispensing device, which is used to be arranged inside the cavity of a filling machine and outside the dispensing hose 13 of the filling machine. It includes a fixing plate 1, a lower clamping plate 2, a middle clamping plate 3, and an upper clamping plate 4. The fixing plate 1 is used to be arranged on the filling machine and around the dispensing hose 13; the lower clamping plate 2 is slidably arranged on the fixing plate 1, and the lower clamping plate 2 is arranged on both sides of the dispensing hose 13. After the lower clamping plate 2 slides, it approaches or moves away from the dispensing hose 13; the middle clamping plate 3 is slidably arranged on the fixing plate 1 and is located above the lower clamping plate 2. The middle clamping plate 3 is arranged on both sides of the dispensing hose 13. After the middle clamping plate 3 slides, it approaches or moves away from the dispensing hose 13; the upper clamping plate 4 is slidably arranged on the fixing plate 1 and is located above the middle clamping plate 3. The upper clamping plate 4 is arranged on both sides of the dispensing hose 13. After the upper clamping plate 4 slides, it approaches or moves away from the dispensing hose 13.
[0033] Through holes are formed in the fixing plate 1, and the dispensing hose 13 passes through the through holes. The two lower clamping plates 2, the two middle clamping plates 3, and the two upper clamping plates 4 are all symmetrically arranged along the radial direction of the dispensing hose 13. The lower clamping plate 2 and the middle clamping plate 3 on the same side of the dispensing hose 13 are both directly below the upper clamping plate 4. The upper clamping plates 4 on the left and right sides and the lower clamping plates 2 on the left and right sides can be completely clamped to completely seal the dispensing hose 13. After the middle clamping plates 3 on the left and right sides approach, they cannot completely seal the dispensing hose 13, and there will be gaps in the dispensing hose 13. During rough-precision feeding, the middle clamping plate 3 and the lower clamping plate 2 are both separated from the dispensing hose 13, so that the upper clamping plates 4 on the left and right sides are intermittently opened and clamped, acting as a on-off valve to prevent the material from falling too fast and causing powdering. During high-precision feeding, the upper clamping plate 4 is separated from the dispensing hose 13. The middle clamping plates 3 on the left and right sides of the dispensing hose 13 approach and clamp the dispensing hose 13, and a gap is left in the dispensing hose 13 to control the flow rate of the material. The lower clamping plates 2 on the left and right sides are quickly opened and closed to achieve precise feeding. During medium-precision feeding, the middle clamping plate 3 is separated from the dispensing hose 13. By alternately opening and closing the upper clamping plates 4 and the lower clamping plates 2 on both sides of the dispensing hose 13, a medium-precision buffer cavity is formed in the part of the dispensing hose 13 between the lower clamping plate 2 and the upper clamping plate 4. A fixed mass of medicine can be stored in the medium-precision buffer cavity. When the shortage value of the dispensing amount is greater than this fixed mass value, all the medicine in the medium-precision buffer cavity can be released, so as to increase the area range of medium-precision feeding, reduce the value of high-precision feeding, thereby shortening the high-precision feeding time and reducing the overall dispensing time, and can speed up the dispensing speed.
[0034] Taking the dispensing of a 10 kg raw material drug (replaced with flour at 0.52 g / ml) as an example, initially, the lower clamping plate 2, the middle clamping plate 3, and the upper clamping plate 4 are all separated from the dispensing hose 13, as Figure 6as shown in a of [Figure 0]; First, feed roughly to about 9 kg, that is, both the middle clamping plate 3 and the lower clamping plate 2 are separated from the dispensing hose 13, and the upper clamping plates 4 on both sides are intermittently opened and clamped, acting as a on-off valve to prevent the powder from being scattered due to too fast material dropping, as Figure 6 shown in b of [Figure 0]; Then, feed to about 9.9 kg with medium precision, that is, the middle clamping plate 3 is separated from the dispensing hose 13, the lower clamping plate 2 clamps for one second and then the upper clamping plate 4 clamps, and then the lower clamping plate 2 opens for two seconds and then closes (the weighing module judges whether the preset value is reached), and then the upper clamping plate 4 is opened again for one second and then clamped, as Figure 6 shown in c and d of [Figure 0]. Repeat the above steps, with each feeding amount about 100 g until the material in the aluminum bucket 15 reaches about 9.9 kg; Finally, feed with high precision to 10 kg, that is, the upper clamping plate 4 is separated from the dispensing hose 13, the middle clamping plates 3 on both sides of the dispensing hose 13 approach and clamp the dispensing hose 13, and a gap is left in the dispensing hose 13 to control the flow rate of the material, and the lower clamping plates 2 on both sides open and close quickly to start precise feeding, as Figure 6 shown in e of [Figure 0]. Each feeding is about 4 g until the feeding reaches 10 kg, and then the lower clamping plate 2, the middle clamping plate 3 and the upper clamping plate 4 are all in the clamped state to complete the dispensing process.
[0035] Furthermore, as Figure 1 and Figure 2 shown, it further includes a first sliding driving mechanism 5. The first sliding driving mechanism 5 has a fixed end and a telescopic end. The fixed end of the first sliding driving mechanism 5 is arranged on the fixed plate 1, and the telescopic end of the first sliding driving mechanism 5 is connected to the lower clamping plate 2. The telescopic movement of the first sliding driving mechanism 5 drives the lower clamping plate 2 to approach or move away from the dispensing hose 13, which is a mechanized operation, saving time and effort. In order to make the connection between the lower clamping plate 2 and the telescopic end of the first sliding driving mechanism 5 more firm and reliable, as Figure 5 shown, the side of the lower clamping plate 2 facing the first sliding driving mechanism 5 bends downward and extends to form a lower connecting plate 16. The lower connecting plate 16 is attached to and locked with the telescopic end of the first sliding driving mechanism 5.
[0036] Furthermore, as Figure 1 and Figure 2 shown, the first sliding driving mechanism 5 is located on the side of the lower clamping plate 2 away from the dispensing hose 13. The first sliding driving mechanism 5 is located outside the lower clamping plate 2 to ensure that the two lower clamping plates 2 have enough contraction space to better adjust the dropping flow rate of the dispensing hose 13. The connection between the first sliding driving mechanism 5 and the fixed plate 1 is a detachable connection, for example, by bolt connection, which is convenient for disassembly, installation and maintenance.
[0037] Furthermore, as Figure 1 and Figure 2As shown, it further includes a second sliding drive mechanism 6. The second sliding drive mechanism 6 has a fixed end and a telescopic end. The fixed end of the second sliding drive mechanism 6 is arranged on the fixed end of the first sliding drive mechanism 5, and the telescopic end of the second sliding drive mechanism 6 is connected to the middle clamping plate 3. By the telescopic movement of the second sliding drive mechanism 6, the middle clamping plate 3 is driven to approach or move away from the dispensing hose 13, which is a mechanized operation, saving time and effort. In order to make the connection between the middle clamping plate 3 and the telescopic end of the second sliding drive mechanism 6 more firm and reliable, as Figure 5 shown, on the side of the middle clamping plate 3 facing the second sliding drive mechanism 6, it bends downward and extends to form a middle connecting plate 17. The middle connecting plate 17 is attached to and locked together with the telescopic end of the second sliding drive mechanism 6.
[0038] Furthermore, as Figure 1 and Figure 2 shown, it further includes a third sliding drive mechanism 7. The third sliding drive mechanism 7 has a fixed end and a telescopic end. The fixed end of the third sliding drive mechanism 7 is arranged on the fixed end of the second sliding drive mechanism 6, and the telescopic end of the third sliding drive mechanism 7 is connected to the upper clamping plate 4. By the telescopic movement of the third sliding drive mechanism 7, the upper clamping plate 4 is driven to approach or move away from the dispensing hose 13, which is a mechanized operation, saving time and effort. In order to make the connection between the upper clamping plate 4 and the telescopic end of the third sliding drive mechanism 7 more firm and reliable, as Figure 5 shown, on the side of the upper clamping plate 4 facing the third sliding drive mechanism 7, it bends upward and extends to form an upper connecting plate 18. The upper connecting plate 18 is attached to and locked together with the telescopic end of the third sliding drive mechanism 7.
[0039] Furthermore, as Figure 1 and Figure 3 shown, it further includes a protective cover 8. The protective cover 8 is arranged on the fixed plate 1. The first sliding drive mechanism 5, the second sliding drive mechanism 6 and the third sliding drive mechanism 7 are all arranged inside the protective cover 8. The telescopic end of the first sliding drive mechanism 5 passes through the protective cover 8 and is connected to the lower clamping plate 2. The telescopic end of the second sliding drive mechanism 6 passes through the protective cover 8 and is connected to the middle clamping plate 3. The telescopic end of the third sliding drive mechanism 7 passes through the protective cover 8 and is connected to the upper clamping plate 4. The protective cover 8 can protect the first sliding drive mechanism 5, the second sliding drive mechanism 6 and the third sliding drive mechanism 7. Without affecting the normal sliding of the lower clamping plate 2, the middle clamping plate 3 and the upper clamping plate 4, it can make the overall appearance more neat and beautiful.
[0040] Furthermore, as Figure 3 and Figure 4As shown in the figure, lower jack 9, middle jack 10, and upper jack 11 are provided on the side wall of the protective cover 8 facing the dispensing hose 13. Lower jack 9, middle jack 10, and upper jack 11 are all long holes. The lower clamping plate 2 is inserted into lower jack 9 to form a sliding fit. The middle clamping plate 3 is inserted into middle jack 10 to form a sliding fit. The upper clamping plate 4 is inserted into upper jack 11 to form a sliding fit. By providing jacks at positions corresponding to the lower clamping plate 2, middle clamping plate 3, and upper clamping plate 4 on the protective cover 8, the opening size of the jacks can be minimized as much as possible, making the protective cover 8 have sufficient strength and making the overall appearance more beautiful.
[0041] Further, as Figure 1 and Figure 2 shown, it further includes a first lifting drive mechanism 12. The upper end of the first lifting drive mechanism 12 is connected to the fixed end of the third sliding drive mechanism 7, and the lower end of the first lifting drive mechanism 12 is connected to the fixed end of the second sliding drive mechanism 6. The fixed end of the third sliding drive mechanism 7 is arranged on the fixed end of the second sliding drive mechanism 6 by means of the first lifting drive mechanism 12. By adjusting the vertical position of the third sliding drive mechanism 7 using the first lifting drive mechanism 12, the vertical position of the upper clamping plate 4 can be adjusted, thereby adjusting the size of the medium-precision buffer chamber and thus adjusting the medium-precision feeding amount per time, which can improve the precision of medium-precision feeding and better meet different feeding requirements.
[0042] Further, it further includes a second lifting drive mechanism. The upper end of the second lifting drive mechanism is connected to the fixed end of the second sliding drive mechanism 6, and the lower end of the second lifting drive mechanism is connected to the fixed end of the first sliding drive mechanism 5. The fixed end of the second sliding drive mechanism 6 is arranged on the fixed end of the first sliding drive mechanism 5 by means of the second lifting drive mechanism. By adjusting the vertical position of the second sliding drive mechanism 6 using the second lifting drive mechanism, the vertical position of the middle clamping plate 3 can be adjusted, thereby adjusting the size of the high-precision buffer chamber and thus adjusting the high-precision feeding amount per time, which can improve the precision of high-precision feeding and better meet different feeding requirements.
[0043] Further, as Figure 1 and Figure 3 shown, the first sliding drive mechanism 5, the second sliding drive mechanism 6, and the third sliding drive mechanism 7 are all arranged at one end of the fixed plate 1, and the dispensing hose 13 is located at the other end of the fixed plate 1. The first sliding drive mechanism 5, the second sliding drive mechanism 6, and the third sliding drive mechanism 7 are all rear-mounted and arranged at the rear of the filling machine. The dispensing hose 13 is located at the front end of the fixed plate 1. After connecting the dispensing head 14 at the lower end of the dispensing hose 13 to the aluminum bucket 15, only the lower clamping plate 2, the middle clamping plate 3, and the upper clamping plate 4 are left above the aluminum bucket 15, which can greatly reduce the blockage of the Class A laminar flow, thereby reducing the risk.
[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered by the scope of the claims of the present invention.
