Description

Technical Field

[0001] The utility model relates to food and drug packaging equipment, in particular to a pellet filling device. Background Art

[0002] With the continuous update of medical drugs, pharmaceutical enterprises are no longer satisfied with filling capsules with single-type drugs, which promotes the development of the pharmaceutical equipment industry towards capsule filling machines with two or more types of drug filling structures. At present, the most common way of mixing and filling two or more types of drugs in the market is to use a metering disk combined with an independent pellet station for mixed filling. Although this filling method can achieve the purpose of mixing and filling two or more types of drugs, it cannot fully meet the market requirements due to the disadvantages such as fragile pellets, unstable filling volume, and high requirements for pellets. In addition, the existing filling equipment generally adjusts the feeding by adjusting the cam curve. For example, a filling metering device and method disclosed in Chinese Patent Document CN117645035A drive the blanking channel to move by using a moving cam, and drive the discharging mechanism to lift by using a lifting cam. The debugging is difficult, the debugging time is long, and with the change of drug types, different specifications of cams need to be replaced, the operation is cumbersome, and the cleaning of the cams is also difficult.

[0028] The present utility model will be further described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0029] Figures 1 to 5 An embodiment of the pellet filling device of the present utility model is shown. The pellet filling device of this embodiment includes a pellet filling module 2 and a filling driving module 3. The filling driving module 3 includes a support member 31 (such as a support column, a support rod, etc.), a support 32 sleeved on the outer periphery of the support member 31, and a lifting driving member (not shown in the figure, such as a cylinder, an electric push rod, etc.) for driving the support member 31 to lift. The pellet filling module 2 includes a feeding assembly 21 and a feeding amount adjusting assembly 22. The feeding assembly 21 is detachably installed on the support member 31, and the feeding amount adjusting assembly 22 is detachably installed on the support 32 for switching and installing the powder filling module 1.

[0030] The pellet filling device of this embodiment adopts a modular design. The feeding assembly 21 of the pellet filling module 2 is detachably installed on the support member 31 of the filling driving module 3, and the feeding amount adjusting assembly 22 is detachably installed on the support 32 of the filling driving module 3, which is convenient for disassembly and assembly. When necessary, the powder filling module 1 can be switched and installed to realize the mixed filling of powder and pellets. Moreover, the powder filling module 1 and the pellet filling module 2 can share the filling driving module 3, thereby reducing the equipment cost.

[0031] Specifically refer to Figure 3, Further, in this embodiment, the feed rate adjustment assembly 22 includes a first mounting plate 221 detachably mounted on the support 32, a second mounting plate 222 located below the first mounting plate 221 and connected to the first mounting plate 221 (for example, connected by a connecting column, a connecting plate, etc.), a material blocking block 223 provided on the first mounting plate 221, a material blocking driving member 224 for driving the material blocking block 223 to reciprocate (preferably, the material blocking driving member 224 is a cylinder, the piston rod of the cylinder is connected to the material blocking block 223, and the expansion and contraction of the piston rod is controlled by a solenoid valve. Of course, in other embodiments, the material blocking driving member 224 can also adopt an electric push rod, a synchronous belt mechanism, etc.) and a blanking member 225 provided on the second mounting plate 222, and the blanking member 225 is connected to the material blocking block 223. The material blocking block 223 can control the on-off at the outlet of the feed assembly 21 (specifically, the on-off at the outlet of the hopper 6) under the drive of the material blocking driving member 224. When the main shaft of the capsule machine rotates to a set angle, the encoder feeds back the angle signal to the PLC control module of the capsule machine, and the PLC control module issues an instruction to the solenoid valve to control the on-off of the air circuit, thereby controlling the expansion and contraction of the piston rod. The piston rod can drive the material blocking block 223 to reciprocate, and the blanking member 225 reciprocates with the material blocking block 223, so as to control the opening and closing of the pellet feeding. Compared with adjusting the cam curve for feed debugging, the difficulty is significantly reduced, the debugging time is greatly shortened, and by adjusting the opening and closing time, it can adapt to various different specifications of pellet feeding without replacing the cam, avoiding the problem of difficult cleaning in the working area due to the presence of the cam, which is beneficial to improving production efficiency.

[0032] Furthermore, in this embodiment, a bearing 226 is provided on the material blocking block 223, and the bearing 226 is connected to the blanking member 225 through a connecting rod 227. Specifically, the material blocking block 223 can act as a bearing seat, and the upper end of the connecting rod 227 can be connected to the inner ring of the bearing 226 through a pin shaft or the like, so that the blanking member 225 can reciprocate with the material blocking block 223.

[0033] As a preferred embodiment, the first mounting plate 221 is mounted on the support 32 through a threaded fastener 4, which has good reliability and is convenient to disassemble. Of course, in other embodiments, it can also be detachably installed by means of a lock, a buckle, etc.

[0034] Further, in this embodiment, the feed assembly 21 includes a lifting plate 211 detachably mounted on the support member 31 and a lifting block 212 provided on the lifting plate 211. For details, see Figure 6, during operation, the lifting drive member drives the support member 31 to lift and lower. The lifting plate 211 and the lifting block 212 move up and down with the support member 31. The lifting block 212 drives the hopper 6 to lift and lower. After the materials in the hopper 6 are lifted, they can fall into the metering channel. When the metering channel is filled with materials, the materials stop entering, and the lifting block 212 drives the hopper 6 to descend. Then, the piston rod of the cylinder drives the blanking member 225 to move, so that the upper end of the blanking channel in the blanking member 225 communicates with the metering channel, and the lower end communicates with the blanking channel. The materials in the metering channel can be filled through the blanking channel and the blanking channel.

[0035] For details, refer to Figure 4 , further, in this embodiment, a first clamping portion 213 is provided on the lifting plate 211, and a locking block 5 is provided on one side of the support member 31. The first clamping portion 213 and the locking block 5 are arranged opposite to each other and are connected by a threaded fastener 4. The threaded fastener 4 locks the first clamping portion 213 and the locking block 5, thereby clamping the support member 31 and realizing the relative fixation of the lifting plate 211 and the support member 31; when the feeding assembly 21 needs to be disassembled, first loosen the threaded fastener 4, and then remove the locking block 5, and the lifting plate 211 and the support member 31 can be separated. The structure is simple and reliable.

[0036] Furthermore, in this embodiment, a first positioning groove 214 is provided on the lifting plate 211. One end of the locking block 5 is located in the first positioning groove 214, and the other end of the locking block 5 is connected to the first clamping portion 213 by a threaded fastener 4. When the threaded fastener 4 is tightened, since one end of the locking block 5 is located in the first positioning groove 214, it can play a limiting role to prevent one end of the locking block 5 from separating from the first clamping portion 213. The structure is reasonable and effective. Compared with both ends of the locking block 5 being fixed by threaded fasteners 4, the number of threaded fasteners 4 can be reduced, and the disassembly and assembly efficiency of the locking block 5 can be improved.

[0037] For details, refer to Figure 1 and Figure 2 , in this embodiment, the powder filling module 1 includes a plunger disc 11 and a powder metering assembly 12. The plunger disc 11 is detachably mounted on the support member 31, and the powder metering assembly 12 is detachably mounted on the support 32.

[0038] For details, refer to Figure 3, Further, in this embodiment, a second clamping portion 111 is provided on the plunger disc 11, and a locking block 5 is provided on one side of the support member 31 (the locking block 5 is a common component when switching between the powder filling module 1 and the pellet filling module 2). The second clamping portion 111 and the locking block 5 are arranged opposite to each other. A second positioning groove 112 is provided on the plunger disc 11. One end of the locking block 5 is located in the second positioning groove 112, and the other end of the locking block 5 is connected to the second clamping portion 111 through a threaded fastener 4. When the threaded fastener 4 is tightened, since one end of the locking block 5 is located in the second positioning groove 112, it can play a limiting role to prevent one end of the locking block 5 from separating from the second clamping portion 111, and the structure is reasonable and effective. Compared with the case where both ends of the locking block 5 are fixed by the threaded fastener 4, the number of threaded fasteners 4 can be reduced, and the disassembly and assembly efficiency of the locking block 5 can be improved. The threaded fastener 4 locks the second clamping portion 111 and the locking block 5, thereby clamping the support member 31 and realizing the relative fixation of the plunger disc 11 and the support member 31. When it is necessary to disassemble the plunger disc 11, first loosen the threaded fastener 4, and then take out the locking block 5, and the plunger disc 11 and the support member 31 can be separated. The structure is simple and reliable.
