Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of capsule processing equipment, and particularly relates to a raw material filling device for capsule processing. Background Art
[0002] Capsule processing equipment is used in the pharmaceutical and food industries. Its primary function is to fill drug powder into capsule shells and seal them completely, creating finished capsules. Capsule processing equipment includes three steps: capsule filling, capsule filling, and capsule sealing. The drug powder is quantitatively filled into the capsule shells on the capsule filling machine. The entire equipment set, from capsule filling to capsule sealing, is housed in a sterile sealed chamber. This means the entire capsule processing process takes place within this sterile, sealed chamber.
[0003] Since most of the drugs filled in capsules are in powder form, there are some tiny gaps between the tray, metering plate and powder box on the capsule filling machine. During the production process, powder will inevitably leak out of these gaps and float in the sterile sealed box. Under the action of static electricity, these powders floating in the sterile sealed box are likely to adhere to the side walls and equipment of the sterile sealed box, causing pollution to the production environment. In addition, these dusts are easy to accumulate in electrical equipment, forming a conductive layer, resulting in the degradation of the insulation performance of the equipment or short circuit failure, and even causing fire accidents.

DETAILED DESCRIPTION
[0057] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0058] Example 1
[0059] A raw material filling device for capsule processing, comprising: a sterile sealed box 1, a feeding device 2, a hopper 3, a raw material filling device, a negative pressure pump 8 and a dust suction component;
[0060] like Figure 1 As shown, the entire capsule processing process of sowing the empty shells of the capsules, separating the capsule caps from the capsule body, filling the medicine, merging the capsule caps with the capsule body, rejecting the empty capsules and discharging needs to be carried out in a sterile sealed box 1 to ensure a sterile environment for the drug raw materials; because this embodiment mainly improves the drug raw material filling equipment for capsules, the equipment involved in sowing the empty shells of the capsules, separating the capsule caps from the capsule body, merging the capsule caps with the capsule body, rejecting the empty capsules and discharging are not shown.
[0061] A feeding device 2 is arranged above the sterile sealing box 1. The structure of the feeding device 2 is the same as that of the feeding device 2 arranged above the existing capsule filling machine; the discharge end of the feeding device 2 is connected to the feed end of the hopper 3, and the discharge end of the hopper 3 is connected to the raw material filling device. The feeding device 2 conveys the medicinal powder raw material into the hopper 3, and the medicinal powder raw material is input into the raw material filling device through the hopper 3, and the drug filling into the capsule shell is completed in the raw material filling device.
[0062] like Figure 3 As shown, the raw material filling device includes: a medicine powder box 4, a quantitative plate 5, a support plate 6, a filling rod and a hydraulic drive assembly;
[0063] A quantitative disk 5 is provided below the powder box 4, and a support plate 6 is provided below the quantitative disk 5. The quantitative disk 5 can rotate relative to the powder box 4 and the support plate 6 under the drive of the rotating assembly; and the edges of the contact surfaces between the powder box 4 and the upper surface of the quantitative disk 5, and the edges of the contact surfaces between the lower surface of the quantitative disk 5 and the upper surface of the support plate 6 are provided with sealing rubber rings. Under the action of the sealing rubber rings, the amount of powder raw materials leaking out from the gap can be reduced;
[0064] The raw material of medicine powder entering into the medicine powder box 4 through the hopper 6 can enter the die hole provided in the quantitative disk 5; a plurality of groups of hydraulic drive components 7 are arranged above the medicine powder box 4, and a plurality of groups of filling rods are arranged in the medicine powder box 4. The hydraulic drive components 7 are used to control the reciprocating movement of the filling rods up and down; the plurality of groups of filling rods take turns to fill the raw material of medicine powder in the die hole of the quantitative disk; the quantitative medicine powder in the last group of die holes is filled into the capsule shell.
[0065] like Figure 4 As shown, the medicine powder box 4 is hollow inside, and the lower bottom surface is set to an open structure, so that the medicine entering the medicine powder box 4 can fall onto the upper surface of the quantitative disk 5, and then enter the die hole in the quantitative disk 5; the center position of the upper surface of the medicine powder box 4 is connected to the discharge end of the hopper 3, and the medicine powder raw materials in the hopper 3 can directly fall into the medicine powder box 4;
[0066] Located inside the powder box 4 and close to the inner wall of the powder box 4, the following are distributed counterclockwise: group a charging rod 403, group b charging rod 404, group c charging rod 405, group d charging rod 406, group e charging rod 407, and group f charging rod 408; each group of charging rods includes a number of independent charging rods. In this embodiment, each group of charging rods is provided with 16 independent charging rods; the upper ends of the 16 independent charging rods in each group of charging rods are all connected to the same charging rod top plate 409; each charging rod top plate 409 is provided with a group of hydraulic drive components 7; driven by the hydraulic drive components 7, the 16 charging rods in the same group of charging rods can move back and forth synchronously.
[0067] The aforementioned hydraulic drive assembly 7 is prior art and will not be described in detail. Its working principle primarily relies on an electric motor driving a hydraulic pump, which converts electrical energy into hydraulic energy. This hydraulic energy is then transferred to the hydraulic actuator via a control valve, thereby achieving telescopic movement of the push rod. The core working principle of the electro-hydraulic push rod is that the rotation of the electric motor drives hydraulic oil through a bidirectional gear pump to generate pressurized oil, which is then transferred to the working cylinder via an oil circuit block, driving the piston rod to achieve reciprocating motion; that is, achieving the synchronous up and down reciprocating movement of the same set of push rods in this embodiment.
[0068] like Figure 3 As shown, the middle part of the quantitative disk 5 is provided with a rotatable turntable 501; the center position of the turntable 501 is provided with a through cylindrical channel; a motor 5018 is provided at the center position of the lower bottom surface of the supporting plate 6 below the quantitative disk 5, and the rotor of the motor 5018 passes through the supporting plate 6 and is connected to the rotating shaft, which is provided in the cylindrical channel at the center of the turntable 501; the rotation of the motor 5018 drives the rotating shaft to rotate, and the rotating shaft drives the turntable 501 to rotate; and the frame of the outer ring of the turntable 501, that is, the outer frame of the entire quantitative disk 5, does not rotate with it;
[0069] Groups a to f of die holes are provided corresponding to the orthographic projection positions of the filling rods in groups a to f in the powder box 4 on the turntable 501; the upper and lower ends of the die holes pass through the upper and lower surfaces of the turntable 501; the number of groups of die holes is equal to the number of groups of filling rods; each group of die holes also includes 16 independent die holes; that is, the number of die holes in each group is equal to the number of filling rods in each group of filling rods; each filling rod faces a die hole.
[0070] The die holes on the turntable 501 will rotate along with the rotation of the turntable 501; Figure 3As shown, the positions of the die holes of group a 5011, group b 5012, group c 5013, group d 5014, group e 5015, and group f 5016 are fixed, and each group of die holes can rotate with the turntable 501. Each group of die holes will rotate from the position of the die hole of group a 5011 to the position of the die hole of group f 5016. Starting from the position of the die hole of group a 5011, the medicine powder raw materials accumulated on the quantitative disk 5 will enter the die hole, and the filling rod above the die hole at the corresponding position will descend to fill the medicine powder in the die hole. When the filling rod rises to the time when it descends again, the medicine powder raw materials will enter the die hole. After a break, the turntable will rotate another angle. For example, within this gap, the same group of die holes will move from group a die hole position 5011 to group b die hole position 5012. During this process, more medicine will enter the die holes. When it moves to group b die hole position 5012, the filling rod just above it will just drop down to refill the medicine powder in group b die hole position 5012. In this way, when the die hole group reaches group f die hole position 5016, the medicine in the die holes is filled and refilled. The filling rod just opposite group f die hole position 5016 drops down to poke the medicine in the die holes into the capsule shell below, completing the medicine powder filling.
[0071] The motor 5018 that controls the rotation of the turntable 501 and the hydraulic drive assembly 7 that controls the filling rod are both controlled by the PLC system. The filling rod's cycle time from rising to descending equals the time it takes the turntable 501 to rotate one die hole position. The filling rod corresponding to die hole position 5016 in group f descends deeper than that of the other groups. This ensures that the drug in the die hole in group f die hole position 5016 is completely inserted into the capsule shell. The filling rod's descending depth is controlled by the hydraulic drive assembly 7.
[0072] After the capsules are arranged by the seeding capsule, they are transferred to the lower part of the support plate 6 on the raw material filling device as the workstation. When they reach the lower part of the support plate 6, the separation structure separates the capsules, separating the capsule cap from the capsule body. The capsule body is located under the support plate 6, waiting to be filled with medicine. Figure 3 As shown, a filling gap 602 is provided at the orthographic projection position of the die hole group f position 5016 on the turntable 501 on the support plate 6; the filling gap 602 is sized to completely frame a group of die holes therein; when a group of die holes rotates to the die hole group f position 5016, it indicates that the inside of the die holes has been filled with medicine powder and enriched, at which time the filling rod directly above descends, and all the medicines in the die holes at the die hole group f position 5016 are pushed into the capsule shell; the empty die holes start rotating again from the die hole group f position 5016, and are gradually filled with medicine and enriched.
[0073] Since the upper surface of the turntable 501 is filled with medicine powder, the die hole at the die hole position 5015 of the group e is already filled with medicine and is waiting to be transferred to the die hole position 5016 of the group f to be filled into the capsule; however, during the process from the die hole position 5015 of the group e to the die hole position 5016 of the group f, the opening above the die hole may still accumulate medicine powder, causing it to be pushed into the capsule together with the medicine powder, thereby increasing the amount of medicine; therefore, Figure 4 As shown, a powder scraper 401 is provided on the side wall of the open structure near the lower bottom surface of the powder box 4, and the lower edge of the powder scraper 401 just contacts the upper surface of the quantitative disk 5 below, that is, the upper surface of the turntable 501; and the powder scraper 401 is provided between the e-group filling rod 407 and the f-group filling rod 408, which is equivalent to the powder scraper 401 being between the e-group mold hole position 5015 and the f-group mold hole position 5016 of the turntable 501; then when a group of mold holes filled with medicine is transferred from the e-group mold hole position 5015 to the f-group mold hole position 5016, the excess medicine powder on the upper end opening of the mold hole will be scraped flat by the powder scraper 401, so that the medicine in a group of mold holes is quantitatively measured and thus filled into the capsule shell.
[0074] Although sealing rubber rings are provided at the edge gaps of the contact surfaces between the powder box 4, the metering disk 5 and the support plate 6 of the capsule raw material filling device, a complete seal is impossible. A small amount of extremely fine powder may still leak from the existing gaps and float in the sterile sealed box 1, thereby polluting the production environment in the sealed box or forming a conductive layer, causing a short circuit in the equipment.
[0075] So, if Figure 1 As shown, a negative pressure pump 8 is provided above the sterile sealed box 1; a dust suction assembly is provided on the negative pressure pump 8, and is used to remove dust from the sterile sealed box 1; the suction end of the dust suction assembly is located next to the raw material filling device; the outlet end of the dust suction assembly is provided on the hopper 3 and communicates with the interior of the hopper 3. Dust leaking from the raw material filling device is sucked into the hopper 3 by the dust suction assembly and reused, thereby minimizing dust in the sterile sealed box 1 without wasting raw materials.
[0076] The dust suction assembly includes: a negative pressure pump connecting pipe 801, a vacuum pipe 9 and a dust suction expansion port 901;
[0077] The upper end of the negative pressure pump connecting pipe 801 is connected to the negative pressure pump 8; the lower end of the negative pressure pump connecting pipe 801 is connected to the vacuum tube 9 and communicates with the inside of the vacuum tube 9; the suction end of the vacuum tube 9 is located next to the raw material filling device, and a number of suction ports are provided on the vacuum tube 9, and each suction port is provided with a dust suction expansion port 901, which can increase the area for dust to enter and make the dust easier to capture; the raw material dust scattered from the raw material filling device is sucked into the vacuum tube 9 from the suction port; the outlet end of the vacuum tube 9 is connected to the side wall of the hopper 3 and communicates with the inside of the hopper 3; finally, the drug raw material dust enters the hopper 3 and is reused.
[0078] Example 2
[0079] Based on Example 1, in Example 1, the vacuum tube 9 is a vertical structure arranged next to the raw material filling device; however, it cannot completely cover the entire circumference of the raw material filling device, so there may be dead corners for suction, resulting in incomplete dust suction.
[0080] like Figure 2 As shown, in this embodiment, the vacuum tube 9 is also provided with several suction ports, each facing the raw material filling device. In this embodiment, two suction ports are provided. Each suction port is provided with an annular tube 902, which is in communication with the vacuum tube 9. The side of the annular tube 902 facing the raw material filling device has several secondary suction ports, each of which is provided with a dust removal expansion port 901. In this way, the annular tube 902 surrounds the raw material filling device from its outer circumference, allowing dust leaking from the raw material filling device to be sucked out 360 degrees, significantly improving the dust removal efficiency.
[0081] Example 3
[0082] Based on Example 1, in Example 1, the lower bottom surface of the medicine powder box 4 is a completely open structure, and the raw materials coming out of the hopper 3 into the medicine powder box 4 directly fall onto the upper surface of the turntable 501 in the metering disk 5; however, there may be some large particles in the medicine powder, such as agglomerated or incompletely ground raw materials; these large particles will affect the quality of the capsules when filled into the capsules.
[0083] like Figure 5 As shown, in this embodiment, a filter screen 402 is provided on the open structure of the lower bottom surface of the medicine powder box 4; the filter screen 402 is provided close to the lower bottom surface of the medicine powder box 4, but there is a certain distance therefrom; the medicine powder is filtered by the filter screen 402, and some large particles of substances are filtered out, allowing only very fine medicine powder to enter the die hole;
[0084] Since the filter screen 402 is provided, it will block the filling rods from descending to the die hole, so each group of filling rods is provided with a filling rod gap 4021 at the positive projection position on the filter screen 402, and each group of filling rods can pass through the corresponding filling rod gap 4021 to reach the die hole.
