Description

Technical Field

[0001] The utility model relates to the technical field of pharmaceutical manufacturing, in particular to a feeding device for a medicine refining machine. Background Art

[0002] In the process of drug production, it is generally completed through several processes. Take the production process of Chinese medicine pills as an example. The first process is a mixer for mixing the medicinal materials of powder and ointment into medicine lumps, and then making the medicine lumps into medicine strips. The medicinal materials made into medicine strips are then transported to the pill making machine for the second process, and the medicinal materials will be rolled into pills on the pill rolling wheel mold in the pill making machine. However, in the prior art, the production time of medicine strips is faster than the production time of pills, so the speed of the pill making machine to make pills is slower than the speed of the mixer to make medicine strips, so that the pill making machine cannot digest too many medicine strips in time. This causes the phenomenon of accumulation of medicinal materials at the feed port of the second process, and some medicinal materials cannot enter the feed port of the second process in time, which will cause the water loss of the medicinal materials for a long time, affecting the quality and aesthetics of the finished product. Utility Model Content

[0003] In view of the above problems, the present utility model is proposed to provide a feeding device for a medicine refining machine that overcomes the above problems or at least partially solves the above problems, and can solve the problem that medicines are accumulated at the feed inlet, which causes the water loss of medicines for a long time and affects the quality of the finished product. The feeding is controlled according to the feed speed, so that the medicines will not be accumulated at the feed inlet of the second process, and the water loss of medicines is prevented.

[0004] Specifically, the utility model provides a feeding device for a medicine refining machine, characterized in that the medicine refining machine includes a discharging device and a feeding device; the feeding device includes:

[0005] The silo body has a storage space arranged inside and an inlet and an outlet communicated with the storage space, wherein the inlet is connected to the discharge port of the discharge device; the outlet is connected to the feed port of the feed device; the silo body also has a movable top wall;

[0006] The detection device is arranged on the silo body, and the detection device is configured to control the discharging device to stop discharging when the top wall moves upward to the first position.

Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0038] Figure 1 is a schematic structural diagram of a feeding device according to an embodiment of the present invention, asFigure 1 as shown in and with reference to Figures 2 to 3 Figures 2 to 3 , an embodiment of the present utility model provides a feeding device for a medicine-making machine. The medicine-making machine includes a discharging device 200 and a feeding device 300. The feeding device includes a bin body and a detection device. The bin body has a storage space 130 provided inside, as well as an inlet 131 and an outlet 132 communicating with the storage space 130. The inlet 131 is connected to the discharging port of the discharging device 200. The outlet 132 is connected to the feeding port of the feeding device 300. The bin body also has a movable top wall 120. The detection device is arranged on the bin body and is configured to control the discharging device 200 to stop discharging when the top wall 120 moves to the first position.

[0039] For the feeding device for a medicine-making machine according to an embodiment of the present utility model, when the medicine-making machine is running, the medicine material in the discharging device 200 enters the inlet 131 of the bin body 100 from the discharging port in the discharging device 200, reaches the storage space 130, and the medicine material enters the feeding port of the feeding device 300 from the outlet 132 communicating with the storage space 130. During the operation, the discharging device 200 continuously supplies the medicine material to the feeding device. When the efficiency of the discharging device is slower than that of the feeding device, at this time, the medicine material will accumulate in the storage space 130. As the medicine material in the storage space 130 gradually increases, the medicine material will apply an upward force to the top wall 120. When the top wall 120 moves upward to reach the first position, the detection device controls the discharging device 200 to stop discharging. At this time, no more medicine material will enter the storage space 130, and the storage space 130 isolates the medicine material from the outside air, so that the moisture of the medicine material will not be lost.

[0040] After the top wall 120 reaches the first position and the discharging device 200 stops discharging, the medicine material in the storage space 130 will continuously enter the feeding device 300 through the outlet 132 of the bin body 100, so that the medicine material in the storage space 130 gradually decreases. After the top wall 120 descends and leaves the first position, at this time, the detection device cannot detect the top wall 120, and controls the discharging device 200 to start and continuously supply the medicine material to the storage space 130. The whole process has a high degree of automation and does not require manual participation, reducing the labor cost in the factory.

[0041] In some embodiments of the present utility model, as Figure 1 and Figure 2 shown, the edge of the top wall 120 is always in contact with the inner surface of the side wall 110 of the bin body 100.

[0042] As can be seen from the above embodiments, the top wall 120 can move upward. In this embodiment, during the movement of the top wall 120, the edges of the top wall 120 are always in contact with the inner surface of the side wall 110 of the bin body 100. That is to say, no matter what position the top wall 120 is in, it will play a role in isolating the storage space 130 from the outside world, so that the moisture of the medicinal materials in the storage space 130 will not be lost, and at the same time, the aesthetic appearance of the surface of the medicinal materials will not be affected.

[0043] In some embodiments of the present invention, as Figure 1 and Figure 2 shown, the discharge port of the discharging device 200 is located above the feeding port of the feeding device 300. The inlet 131 is provided on one of the side walls 110 of the bin body 100. The outlet 132 is provided on the bottom wall of the bin body 100.

[0044] In this embodiment, the medicinal materials enter the bin body 100 through the inlet 131 of the discharging device 200, then enter the storage space 130 through the inlet 131 of the bin body 100, and then move downward under the action of gravity to reach the outlet 132 of the bin body 100, and then enter the feeding device 300 through the feeding port of the feeding device 300. Since the discharge port of the discharging device 200 is located above the feeding port of the feeding device 300, that is to say, the inlet 131 of the bin body 100 is above the outlet 132 of the bin body 100, the medicinal materials in the storage space 130 move downward under the influence of gravity to reach the outlet 132, avoiding the situation that the medicinal materials in the storage space 130 are not all discharged due to the lack of driving force.

[0045] In some embodiments of the present invention, as Figure 1 and Figure 2 shown, the top wall 120 is rotatably connected to the side wall 110 of the bin body 100.

[0046] As can be seen from the above embodiments, the storage space 130 is used to store medicinal materials, and the top wall 120 can move upward to expand the storage space 130. In this embodiment, since the top is rotatably connected to the side wall 110 of the bin body 100, when the medicinal materials continuously enter the storage space 130, as the medicinal materials accumulate, the accumulation position of the medicinal materials in the storage space will gradually rise. So that the rotatable end of the top wall 120 rotates upward as the medicinal materials continue to enter. When the top wall 120 reaches the first position, the detection device controls the discharging device 200 to stop discharging. The structure is very simple.

[0047] In some embodiments of the present invention, as Figure 1 and Figure 2As shown, the feeding device further includes at least one rotating shaft 140, which is arranged on the side wall 110 of the bin body 100 and is located at one end of the side wall 110 close to the discharge port. The rotating shaft 140 is higher than the upper end of the discharge port and is used to rotatably connect the top wall 120 to the side wall 110.

[0048] As can be seen from the above embodiments, when the medicinal materials are piled up to a certain height in the storage space 130, the continuous entry of the medicinal materials will cause the rotatable end of the top wall 120 to rotate upward. In this embodiment, when the height of the medicinal materials reaches the lowest point of the top wall 120, the continuously entering medicinal materials will push the opposite end of the top wall 120 connected to the rotating shaft 140 upward. Moreover, since the rotating shaft 140 is located at one end of the side wall 110 close to the discharge port and the rotating shaft 140 is higher than the upper end of the discharge port, the inlet 131 of the bin body 100 will not be blocked, ensuring the smoothness of the process of the medicinal materials from the discharging device 200 to the storage space 130.

[0049] In some embodiments of the present invention, as Figure 1 and Figure 2 shown, the top wall 120 is connected to the side wall 110 of the bin body 100 in a vertically movable manner.

[0050] As can be seen from the above embodiments, when the medicinal materials are piled up to a certain height in the storage space 130, the continuous entry of the medicinal materials will cause the rotatable end of the top wall 120 to move upward. In this embodiment, since the top wall 120 is connected to the side wall 110 of the bin body 100 in a vertically movable manner, when the medicinal materials continue to enter the storage space 130, as the medicinal materials are piled up, the stacking position of the medicinal materials in the storage space will gradually rise. So that the top wall 120 moves upward. When the top wall 120 reaches the first position, the detection device controls the discharging device 200 to stop discharging. The structure is very simple.

[0051] In some embodiments of the present invention, as Figure 1 and Figure 2 shown, the top wall 120 is located inside the side wall 110 of the bin body 100. The feeding device further includes a first stopper. The first stopper is arranged inside the side wall 110 and is located above the inlet. The top wall 120 is arranged above the first stopper.

[0052] As can be seen from the above embodiments, the top wall 120 is movably connected to the side wall 110 of the silo body 100 in the up and down direction. In this embodiment, when the top contacts the first stop block, the top wall 120 is in the lowest position. Since the first stop block is located above the discharge port of the discharging device 200, the top wall 120 is arranged above the first stop block so that the top wall 120 does not block the inlet 131 of the silo body 100, ensuring the smoothness of the process of the medicinal material reaching the storage space 130 from the discharging device 200. It prevents the medicinal material from being blocked between the discharge port of the storage space 130 and the inlet 131 of the silo body 100 due to the top wall 120 blocking the inlet 131.

[0053] In some embodiments of the present invention, as Figure 1 and Figure 2 , Figure 3 shown, the detection device includes a mounting plate 160, a sensor 153, a rotating rod 151 and an induction sheet 152. The mounting plate 160 is arranged on the outer surface of the side wall 110 and is flush with the rotating shaft 140. The sensor 153 is mounted on the mounting plate 160. One end of the rotating rod 151 is arranged on the rotating shaft 140, and the other end of the rotating rod 151 faces away from the discharge port. The rotating rod 151 is located outside the side wall 110. The rotating rod 151 is always parallel to the top wall 120. The induction sheet 152 is arranged at the end of the rotating rod 151 away from the discharge port and is configured to be close to or contact the sensor 153 when the top wall 120 is in the first position.

[0054] As can be seen from the above embodiments, the top wall 120 is rotatably connected to the side wall 110 of the silo body 100. In this embodiment, the side of the top wall 120 connected to the rotating shaft 140 is arranged parallel to the rotating rod 151. When the top wall 120 rotates upward on the side wall 110, the rotating rod 151 rotates synchronously with the top wall 120. During the upward rotation, when the induction sheet 152 on the rotating rod 151 approaches or contacts the sensor 153, the sensor 153 detects the induction sheet 152. At this time, the top wall 120 reaches the first position and the discharging device 200 stops discharging. Automatic control saves manpower.

[0055] In some embodiments of the present invention, as Figure 1 and Figure 2 shown, the feeding device further includes a second stop block, which is arranged on the outer surface of the side wall 110 and is located below the rotating rod 151 and is configured to stop after the rotating rod 151 rotates downward by a preset angle.

[0056] As can be seen from the above embodiments, the rotating rod 151 rotates synchronously with the top wall 120. In this embodiment, when the top wall 120 is in the first position, as the medicinal material in the storage space 130 gradually discharges from the outlet 132 of the bin body 100 out of the storage space 130, the top wall 120 gradually rotates downward, and the rotating rod 151 rotates synchronously with the top wall 120. When the rotating rod 151 contacts the lower second stopper, the rotating rod 151 stops rotating, and further the top wall 120 stops rotating. The setting of the second stopper prevents the top wall 120 from closing the inlet 131 of the bin body 100 when there is no medicinal material or less medicinal material in the storage space 130.

[0057] Furthermore, when there is less medicinal material in the storage space 130, the top wall 120 will not directly fall, resulting in a gap between the top wall 120 and the side wall 110, preventing air from entering the storage space 130 and preventing the medicinal material in the storage space 130 from drying out. Further prevent the quality of the finished product made from the medicinal material from deteriorating due to the drying of the medicinal material, or prevent the appearance of the finished product made from the medicinal material from being affected due to the drying of the medicinal material. The feeding device ensures the quality of the finished product while also taking into account the appearance of the finished product.

[0058] In some embodiments of the present utility model, as Figure 1 and Figure 2 shown, the bin body 100 includes a trough and a connecting plate 170. The opening of the trough is the inlet 131. The bottom wall of the trough is the outlet 132. The connecting plate 170 is connected to the edges of the inlet 131 and the outlet 132 and inclines outward from the bin body 100.

[0059] In this embodiment, during the installation and feeding process, first align the inlet 131 of the bin body 100 with the outlet of the discharging device 200, and then abut the connecting plate 170 at the inlet 131 against the discharging device 200, so that the discharging port of the discharging device 200 covers the inlet 131 of the bin body 100. Isolate the outside from the discharging port of the discharging device 200 to prevent the medicinal material coming out of the discharging port from reaching areas outside the bin body 100.

[0060] Align the outlet 132 of the bin body 100 with the inlet of the feeding device 300, and then abut the connecting plate 170 at the outlet 132 against the feeding device 300, so that the inlet of the feeding device 300 covers the outlet 132 of the bin body 100. Isolate the outside from the inlet of the discharging device 200 to prevent the medicinal material coming out of the outlet 132 from reaching areas outside the feeding device 300. Effectively reduce the contact area between the medicinal material and the outside air and prevent the outside air from affecting the medicinal material.

[0061] At this point, those skilled in the art should recognize that although numerous exemplary embodiments of the present utility model have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present utility model can still be directly determined or derived based on the content disclosed in the present utility model without departing from the spirit and scope of the present utility model. Therefore, the scope of the present utility model should be understood and recognized as covering all such other variations or modifications.
