Description

Technical Field

[0001] The invention relates to the field of capsule filling, in particular to a capsule liquid filling machine. Background Art

[0002] Capsule filling machines are automated equipment used in the pharmaceutical industry to fill drugs into capsule shells. These devices are usually composed of feeding, filling, sealing and control systems, and can automate the entire process from capsule separation, drug filling to capsule sealing. However, traditional capsule filling machines only fill powdered or granular drugs into capsules, and liquid drugs cannot be added through automated equipment.

[0003] A Chinese utility model patent with publication number "CN210355393U" discloses a fully automatic capsule processing line, including a body, a capsule filling unit at one longitudinal end of the body, and a capsule drying unit at the other end, the capsule filling unit and the capsule drying unit are connected by a capsule sealing unit, the capsule filling unit includes a feeding mechanism, a liquid adding mechanism, a pressing mechanism, a capsule discharging mechanism and a turntable mechanism, the feeding mechanism, the liquid adding mechanism, the pressing mechanism and the capsule discharging mechanism are rotatably connected by the turntable mechanism, the capsule sealing unit includes a capsule conveying track circulating along the capsule filling unit toward the capsule drying unit, the capsule conveying track is evenly distributed with capsule receiving grooves for placing capsules, and a sealing mechanism is provided on the capsule conveying track. The sealing mechanism includes a glue box and at least one rotatable shaft mounted on the glue box, a glue sealing wheel is mounted on the shaft, a part of the glue sealing wheel is inside the glue box, and another part is outside the glue box, a scraper plate is provided at a part of the glue sealing wheel outside the glue box, and a scraper groove is provided on the scraper plate for the glue sealing wheel to pass through.

[0004] However, the above-mentioned fully automatic capsule processing line still has the following defects: the fully automatic capsule processing line uses a capsule sealing unit to perform secondary sealing after sealing the edges of the capsules through a pressing mechanism. The capsule sealing unit rotates and applies the sealing liquid to the pressed edges of the capsules for sealing. Since the sealing liquid needs to be applied to the surface of the capsule, even if the excess sealing liquid is scraped off by a scraper, the pressed edges of the capsules may not be applied or too much sealing liquid may remain. The capsules will leak or stick in the subsequent production process, which increases the unqualified rate of the capsules and also pollutes the machine. Summary of the invention

[0005] The purpose of the present invention is to provide a capsule filling machine to solve the above problems existing in the prior art.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a capsule filling machine, including a body, on which a feeding mechanism, a filling mechanism, a pressing mechanism and a turntable mechanism are arranged, the feeding mechanism, the filling mechanism and the pressing mechanism are rotatably connected through the turntable mechanism, the turntable mechanism is located at the rear end of the pressing mechanism and is also provided with a transfer mechanism, the end of the transfer mechanism away from the turntable mechanism is provided with a sealing mechanism, the sealing mechanism includes a sealing turntable, a plurality of groups of second capsule transport and release components distributed on the periphery of the sealing turntable and distributed along the circumference of the sealing turntable, and a hot melt device arranged in the middle of the second capsule transport and release component, the second capsule transport and release component is clamped at both ends of the capsule, the hot melt device is attached to the pressing part of the capsule cap and the capsule body of the capsule, and the hot melt device heats to achieve hot melt sealing of the capsule.

[0007] By adopting the above technical scheme: the capsule enters the filling machine through the feeding mechanism, the turntable mechanism separates the capsule and then rotates it to the filling mechanism, the filling mechanism fills the capsule in the correct position with liquid, and then the turntable rotates to the pressing mechanism, the pressing mechanism presses the capsule cap and the capsule body again to lock the edges into a capsule as a whole and then enters the transfer mechanism, the transfer mechanism sends the capsule into the second capsule transport and release component of the sealing mechanism, and then the hot melt device in the second capsule transport and release component starts to heat the pressing part of the capsule cap and the capsule body of the capsule to a certain extent, so that the pressing part is hot-melted without affecting the appearance of the capsule, and the sealing of the capsule is further improved, thereby preventing the capsule from leaking due to loose pressing in the subsequent production process, and at the same time, the sealing liquid is no longer needed at the sealing point, which solves the problems of uneven sealing and unclean scraping caused by sealing with sealing liquid, avoids the contamination of the machine body by the sealing liquid, and improves the qualified rate of the capsule.

[0008] The above-mentioned capsule filling machine can be further configured as follows: the hot melt device includes a first hot melt sheet, a second hot melt sheet and a hot melt rod for heating the hot melt sheets, the first hot melt sheet and the second hot melt sheet are arranged in relative contact with each other, a contact portion of the first hot melt sheet and the second hot melt sheet is provided with a plurality of hot melt openings, the inner periphery of the hot melt opening is fitted with the outer periphery of the sealing edge of the capsule, and the hot melt device realizes hot melt edge sealing of the sealing edge through the hot melt openings.

[0009] By adopting the above technical solution: the hot melt rod first provides a certain amount of heat to the first hot melt sheet and the second hot melt sheet, so that the first hot melt sheet and the second hot melt sheet reach the specified hot melt temperature. Since the inner periphery of the hot melt opening formed by the first hot melt sheet and the second hot melt sheet fits with the outer periphery of the sealing edge of the capsule, the heat of the first hot melt sheet and the second hot melt sheet can be conducted to the sealing edge, thereby realizing hot melt edge sealing of the sealing edge of the capsule.

[0010] The capsule filling machine can be further configured as follows: the second capsule operational amplifier assembly includes an operational amplifier fixing frame, a first operational amplifier block, a second operational amplifier block, an operational amplifier sliding rod, an operational amplifier clamping sheet, and an operational amplifier clamping block; accommodating grooves are provided on both sides of the top of the operational amplifier clamping block; the operational amplifier clamping sheet is arranged in the accommodating groove and fixedly connected to the operational amplifier clamping block; the operational amplifier clamping sheet and the operational amplifier clamping block are provided with corresponding third capsule placement grooves; the first hot melt sheet and the second hot melt sheet are arranged in a space formed by the operational amplifier clamping sheet and the operational amplifier clamping block; the first hot melt sheet is fixed under the first operational amplifier block The second hot melt sheet is fixed under the second transport sheet, a moving block is provided at the end of the transport sliding rod, and a separation device is provided under the moving block, and the separation device is used to separate the first hot melt sheet from the second hot melt sheet; a discharging mechanism is provided at the end of the sealing mechanism away from the transfer mechanism, the discharging mechanism includes a discharging rack, a discharging plate and a discharging rod for discharging, the discharging rod is arranged on the side of the discharging plate close to the sealing mechanism, the discharging rack can move in the longitudinal direction, the discharging rack is linked with the separation device, and the discharging rod can push out the capsule located in the third capsule placement groove.

[0011] By adopting the above technical solution: when the capsule is about to be transferred to the sealing mechanism, the separation device drives the moving block to move backward, and at this time the second amplifier block moves backward and drives the first hot melt sheet to separate from the second hot melt sheet, and then the capsule passes through the transfer mechanism and enters the third capsule placement slot of the amplifier clamping sheet and the amplifier clamping block, the separation device is reset to make the first hot melt sheet and the second hot melt sheet fit together again, and the hot melt opening is clamped and fitted with the sealing edge of the capsule, which effectively improves the stability of the capsule in the second amplifier assembly and prevents the capsule from falling during the production process. Since the first hot melt sheet and the second hot melt sheet can be separated from each other, the capsule will not stick to the second amplifier assembly, which effectively improves the stability of the machine. In addition, the discharging mechanism is linked with the separating device, and the separating device moves up simultaneously with the discharging rod. At this time, the first hot melt sheet is separated from the second hot melt sheet, and the capsule becomes loose relative to the second capsule transport and placement assembly. When the discharging rod moves down, the capsule in the third capsule placement groove is ejected from the second capsule transport and placement assembly, and the first hot melt sheet is reset and fitted with the second hot melt sheet again, which effectively improves the production efficiency and can accurately control the discharging of the capsule, reduce the damage of the capsule during the discharging process, thereby improving the capsule quality and appearance.

[0012] The above-mentioned capsule filling machine can be further configured as follows: the turntable mechanism includes a rotatable first turntable, several groups of first capsule transport and placement components distributed on the outer periphery of the first turntable and distributed along the circumference of the first turntable, the first capsule transport and placement components include a first capsule transport and placement rack and a second capsule transport and placement rack, the first capsule transport and placement rack is provided with a first capsule placement slot, and the second capsule transport and placement rack is provided with a second capsule placement slot; the first capsule transport and placement rack is linked to a first connecting rod distributed in a direction perpendicular to the axis of the first turntable, the second capsule transport and placement rack is linked to a second connecting rod distributed in a direction parallel to the axis of the first turntable, the first connecting rod is located at an end away from the first capsule transport and placement rack and is linked to a linear bearing, the second connecting rod is located at an end away from the second capsule transport and placement rack and is linked to a roller, a base is provided under the first turntable, a guide surface is provided on the base, and a plurality of groups of high points and a plurality of groups of low points are provided on the guide surface.

[0013] By adopting the above technical solution: by reasonably distributing the arrangement order of the low points and the high points, the relative positions of the first capsule transport rack and the second capsule transport rack can be changed. After the first turntable receives the capsules transported by the feeding mechanism, in order to add soft capsules or pills, the capsule cap and the capsule body must be separated, the first capsule transport assembly rises to the high point, the first capsule transport rack and the second capsule transport rack are separated up and down, and the capsule cap and the capsule body can be separated; when the first capsule transport rack and the second capsule transport rack move to the pressing mechanism, the first capsule transport assembly drops to the low point, and the first capsule transport rack and the second capsule transport rack can be transformed into a mutually stacked state, which is convenient for the pressing mechanism to press the capsule cap and the capsule body to realize the preliminary pressing of the capsule; in addition, when the first capsule transport rack and the second capsule transport rack move to the waste rejection mechanism, due to the existence of unqualified capsules, the first capsule transport rack and the second capsule transport rack cannot be kept in a stacked state, and need to be kept in a dislocated or parallel state to better reject waste, so it can be achieved by adopting the above technical solution.

[0014] The above-mentioned capsule filling machine can be further configured as follows: the feeding mechanism includes a feeding rack, the feeding rack is fixed on the machine body, a feeding bin is fixed above the feeding rack, the feeding rack is provided with a longitudinal guide rod, the longitudinal guide rod is provided with a longitudinal slider, a capsule input block is provided below the feeding bin, the capsule input block is fixed on the slider, a plurality of through capsule input channels are provided on the capsule input block, a capsule transferring device which can transfer the capsule inside to the capsule output channel is provided at the lower port of the capsule input channel, a capsule output block is provided below the capsule input block, the capsule output block is provided with a plurality of capsule output channels corresponding to the capsule input channel, a pushing mechanism is provided at the end of the capsule output channel away from the turntable mechanism, a linkage device is provided above the pushing mechanism, the linkage device can drive the capsule input block to move up and down, the linkage device can drive the pushing mechanism to move horizontally, and can push the capsule in the capsule output channel to above the turntable mechanism, and a pushing block is provided on the side of the capsule input block close to the turntable mechanism, and the pushing block is linked with the capsule input block. The ejection mechanism comprises a slide rail, a transverse slide block and ejection blocks for ejecting capsules corresponding to the number of capsule output channels, which are arranged on the machine body. The ejection block is fixedly connected to the transverse slide block.

[0015] By adopting the above technical scheme: the capsule is input through the capsule input channel, and as the slider moves longitudinally on the longitudinal guide rod, the capsule input channel is connected with the capsule output channel, and then under the action of the capsule feeding device, the capsule is dialed from the capsule input channel to the capsule output channel. Since the capsule input block and the ejection mechanism slide synchronously through the linkage device, the longitudinal movement of the longitudinal slider and the transverse movement of the transverse slider can be performed synchronously, that is, when the transverse slider moves backward, the longitudinal slider moves downward, so as to realize the transfer of the capsule from the capsule input channel to the capsule output channel. Thereafter, the longitudinal slider is reset upward and the transverse slider moves forward, and the ejection block realizes the transverse pushing of the capsule from the capsule output channel to the end of the capsule output channel, and the cycle is repeated. Then the longitudinal slider moves downward to drive the pushing block to move downward to push the capsule located at the end of the capsule output channel into the first capsule operation and placement assembly, thereby greatly improving the production efficiency.

[0016] The capsule filling machine can be further configured as follows: the linkage device includes a rotating shaft and a sleeve, rotating bearings are provided on both sides of the feed frame, both ends of the rotating shaft are inserted into the rotating bearings, the sleeve is rotatably arranged on the rotating shaft, and the sleeve is provided with three radially extending swing arms, the first swing arm and the second swing arm are hinged at the end with a connecting block, the first swing arm is connected to the rear side of the capsule input block through the connecting block, the second swing arm is connected to the transverse slider through the connecting block, and the third swing arm is connected to the driving device.

The driving device only needs to move the third swing arm longitudinally to drive the reciprocating motion of the first swing arm and the second swing arm, which is convenient and quick.

[0018] The above-mentioned capsule filling machine can be further configured as follows: a blanking mechanism is provided between the filling mechanism and the waste rejection mechanism, the blanking mechanism includes a blanking bracket, a blanking bin, and a blanking input block, the blanking bracket includes a first fixed plate and a second fixed plate, the blanking bin is fixed on the first fixed plate, the blanking input block is fixed on the second fixed plate, the blanking input block is provided with a plurality of blanking input channels, the blanking input channels run through the blanking input block, a blanking control mechanism is provided on the back of the second fixed plate, a plurality of openings corresponding to the blanking input channels are provided on the bottom of the second fixed plate, and the blanking control mechanism controls the filling of soft capsules or pills into the capsule body through the openings.

[0019] By adopting the above technical solution: by placing the medicines that need to be mixed and filled into the blanking bin, the medicines enter the blanking input channel on the blanking input block through the blanking bin, and the blanking control mechanism controls the medicines in the blanking input channel to enter the capsule in a quantitative and orderly manner through the opening on the second fixed plate, thereby ensuring that the content of mixed medicines in the capsule remains consistent.

[0020] The capsule filling machine can be further configured as follows: a detection mechanism is provided between the feeding mechanism and the filling mechanism, a waste rejection mechanism is provided between the filling mechanism and the pressing mechanism, the detection mechanism comprises a detection frame and a plurality of mounting holes, a sensor detachably fixedly mounted on the detection frame is provided in the mounting hole, the detection mechanism is connected with the waste rejection mechanism by signal, the waste rejection mechanism comprises a waste rejection frame, a suction port for sucking capsules is provided on the upper part of the waste rejection frame, the waste rejection frame is linked to a push rod, the push rod is located at the end away from the waste rejection frame and is linked to an ejector, and the ejector is distributed below the suction port.

[0021] By adopting the above technical solution: the detection mechanism detects whether the capsule has entered the turntable mechanism or whether the position is correct, the sensor on the detection frame can detect the capsule in the first capsule transport assembly, and then transmits the detection signal to the waste rejection mechanism. The waste rejection frame of the waste rejection mechanism is connected to the pneumatic component, so that the waste capsule can be rejected by the suction force generated by the suction port, and the push rod drives the ejector pin to push the waste capsule toward the suction port, so that the waste capsule can be rejected more accurately and effectively, thereby improving the working effectiveness and stability of the waste rejection mechanism, and there will be no missed rejection phenomenon, so that accurate waste rejection can be achieved.

[0022] The above-mentioned capsule filling machine can be further configured as follows: the filling mechanism includes a filling frame, a pump body, a piston rod, and a rotating shaft. The filling frame is fixed on the machine body, the pump body is fixed on the filling frame, the pump body is placed vertically, the piston rod and the rotating shaft are respectively arranged on the pump body from both ends of the axial direction, the inner end of the piston rod and the inner end of the rotating shaft both extend into the inner cavity of the pump body, the inner end of the piston tube is provided with a liquid guide groove, the outer end of the piston rod is connected to a lifting drive mechanism that drives it to rise and fall relative to the pump body, the lifting drive mechanism includes a lifting drive motor, a lifting rod, and a lifting plate, the lifting rod is fixedly connected to the lifting drive motor, the lifting plate is connected to the lifting rod, and the outer end of the piston rod is fixedly connected to the lifting plate. The outer end of the rotating shaft is connected to a rotating drive mechanism that drives it to rotate back and forth relative to the pump body, the rotating drive mechanism includes a rotating drive motor and a transmission gear set, and the outer end of the rotating shaft is connected to the rotating motor through a transmission gear set. A liquid inlet interface and a liquid outlet interface are radially extended on the pump body, and the liquid inlet interface and the liquid outlet interface are both connected to the inner cavity of the pump body.

[0023] By adopting the above technical solution: the rotary drive mechanism drives the rotary shaft to rotate, so that the liquid guide groove on the rotary shaft can be connected with the liquid inlet interface on the pump body. At this time, the piston rod is pulled outward under the drive of the lifting drive mechanism, and the liquid medicine can be sucked into the pump body cavity through the liquid inlet interface. Then, the rotary drive mechanism drives the rotary shaft to rotate in the opposite direction, so that the liquid guide groove on the rotary shaft can be connected with the liquid outlet interface on the pump body. At this time, the piston rod is plugged inward under the drive of the lifting drive mechanism, and the previously sucked liquid medicine can be squeezed out through the liquid outlet interface, so that the operation of fully automatically adding liquid medicine into the capsule can be realized through the liquid adding output pipe.

[0024] The capsule filling machine can be further configured as follows: a control panel is provided above the machine body, the control panel comprises a display screen, control buttons and a control knob, and the control panel is hinged to the machine body.

[0025] By adopting the above technical solutions: the control panel equipped with the capsule filling machine greatly improves the convenience of operation and the human-machine interaction experience. The control panel integrates a display screen, control buttons and control knobs, allowing operators to intuitively and quickly adjust machine parameters and monitor operating status, optimizing the human-machine interaction interface. In addition, the hinged design of the control panel increases the flexibility of use, allowing the panel position to be adjusted according to the needs of the operator, and is also more convenient for maintenance and cleaning.

[0026] The beneficial effects of the present invention are: 1. The capsule filling machine provided by the present invention first seals the capsule through a pressing mechanism, and then transfers the capsule to the sealing mechanism through a transfer device. The hot melt device in the sealing mechanism performs hot melt sealing on the sealing edge of the capsule, thereby reducing the use of sealing liquid and effectively preventing leakage caused by loose capsule pressing and contamination of the machine.

[0027] 2. Through the cooperation between the second capsule transport and placement component and the hot melt device, when the transfer mechanism transfers the capsule to the sealing mechanism, the second capsule transport and placement component can first perform simple transport and placement of the capsule, and the hot melt opening of the hot melt device provides stable transport and placement. The combination of the two keeps the capsule stable during the hot melt process, and the problem of capsule falling will not occur. At the same time, the discharging mechanism at the rear end of the sealing mechanism is linked with the separation device. When the capsule is discharged, the hot melt opening will not clamp the capsule, which effectively improves the production efficiency. At the same time, it can accurately control the discharging of the capsule, reduce the damage of the capsule during the discharging process, and improve the appearance quality of the capsule.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Figures 1 to 19A capsule filling machine shown in the figure comprises a body 1, on which a feeding mechanism 2, a filling mechanism 3, a pressing mechanism 11 and a turntable mechanism 5 are arranged, the feeding mechanism 2, the filling mechanism 3 and the pressing mechanism 11 are rotatably connected through the turntable mechanism 5, the turntable mechanism 5 is located at the rear end of the pressing mechanism 11 and is also provided with a transfer mechanism 6, the end of the transfer mechanism 6 away from the turntable mechanism 5 is provided with a sealing mechanism 7, the sealing mechanism 7 clamps and places the capsule through a second capsule transportation and placement component 72 located on the sealing turntable 71, and then a hot melt device 73 in the middle of the second capsule transportation and placement component starts to hot-melt the sealing edge of the capsule, the hot melt device 73 comprises a first hot melt sheet 731, a second hot melt sheet 732 and a hot melt rod 733 for heating the hot melt sheet, a contact portion of the first hot melt sheet 731 and the second hot melt sheet 732 is provided with a plurality of hot melt openings 735, and the hot melt device 73 realizes hot-melt edge sealing of the sealing edge through the hot melt openings 735.

[0032] Working principle of sealing mechanism 7: when the capsule is moved from transfer mechanism 6 to the second capsule transport assembly 72 of sealing mechanism 7, the sealing edge of the capsule is located in the hot melt opening 735, and the hot melt rod 733 starts to heat the first hot melt sheet 731 and the second hot melt sheet 732, and the first hot melt sheet 731 and the second hot melt sheet 732 transfer heat to the hot melt opening 735. Since the hot melt opening 735 fits the sealing edge of the capsule, the heat of the first hot melt sheet 731 and the second hot melt sheet 732 hot-melts the pressing part of the capsule cap and the capsule body, so that the sealing of the capsule is further improved, thereby preventing the leakage of the capsule due to loose pressing in the subsequent production process. At the same time, the sealing liquid is no longer needed at the sealing point, which solves the problems of uneven sealing and unclean scraping caused by sealing with sealing liquid, avoids the contamination of the body by the sealing liquid, and improves the qualified rate of the capsule. like Figures 1 to 5The second capsule op-amp assembly 72 shown includes an op-amp fixing frame 721, a first op-amp block 722, a second op-amp block 723, an op-amp sliding rod 727, an op-amp clamping piece 724, and an op-amp clamping block 725. The top two sides of the op-amp clamping block 725 are provided with receiving grooves 7251. The op-amp clamping piece 724 is arranged in the receiving groove 7251 and is fixedly connected to the op-amp clamping block 725. The op-amp clamping piece 724 and the op-amp clamping block 725 are provided with corresponding third capsule op-amps. The first hot melt sheet 731 and the second hot melt sheet 732 are arranged in the space formed by the op amp clamping sheet 724 and the op amp clamping block 725, the first hot melt sheet 731 is fixed under the first op amp block 722, the second hot melt sheet 732 is fixed under the second op amp sheet 723, a moving block 734 is provided at the end of the op amp sliding rod 727, and a separating device 74 is provided under the moving block 734, and the separating device 74 is used to separate the first hot melt sheet 731 from the second hot melt sheet 732. When the capsule is moved from the transfer mechanism 6 to the third capsule placement groove 726 on the second capsule transport assembly 72 of the sealing mechanism 7, the separation device 74 on the transport fixing frame 721 drives the moving block 734 to move backward and then pulls the moving sliding rod 727 to move. At this time, the second transport block 723 is pulled backward by the moving sliding rod 727 to separate the first hot melt sheet 731 from the second hot melt sheet 732. After the capsule passes through the transfer mechanism 6 and enters the third capsule placement groove 726 of the transport clamping sheet 724 and the transport clamping block 725, the separation device 74 is reset to make the first hot melt sheet 731 contact the second hot melt sheet 732 again, and the hot melt opening 735 clamps and fits the sealing edge of the capsule, thereby improving the stability of the capsule in the sealing mechanism 7.

[0033] like Figure 1 , Figure 2 , Figure 6 The sealing mechanism 7 shown is provided with a discharging mechanism 75 at one end away from the transfer mechanism 6. When the sealing mechanism 7 completes the hot-melt edge sealing of the capsule, the sealing turntable 71 rotates and moves to the rear discharging mechanism 75. Since the sealing mechanism 7 is linked with the separation device 74 through the discharging mechanism 75, the discharging rod 752 moves up and the separation device 74 moves up at the same time. At this time, the first hot melt sheet 731 is separated from the second hot melt sheet 732, and the capsule becomes loose relative to the second operation and release component 72. When the discharging rod 752 moves down, the capsule in the third capsule placement groove 726 is ejected from the second operation and release component 72. At the same time, the first hot melt sheet 731 and the second hot melt sheet 732 are reset and fitted again, and the second capsule operation and release component 72 is rotated back to the transfer mechanism 6 to perform hot-melt edge sealing of the capsule, which effectively improves the production efficiency and can accurately control the discharging of the capsule to reduce the damage of the capsule during the discharging process, thereby improving the quality and appearance of the capsule.

[0034] like Figure 1 , Figure 2 , Figures 7 and 8The turntable mechanism 5 shown can change the relative positions of the first capsule transport rack 521 and the second capsule transport rack 523 by reasonably distributing the low point 542 and the high point 541. After the first turntable 51 receives the capsules transported by the feeding mechanism 2, in order to add soft capsules or pills, the capsule cap and the capsule body must be separated, and the first capsule transport assembly 52 rises to the high point 541, and the first capsule transport rack 521 and the second capsule transport rack 523 are separated from each other, so that the capsule cap and the capsule body can be separated; when the first capsule transport rack 521 and the second capsule transport rack 523 move to the pressing mechanism 11, the first capsule transport assembly 52 drops to the low point 542, and the first capsule transport rack 521, The second capsule transport rack 523 can be transformed into a stacked state, which is convenient for the pressing mechanism 11 to press the capsule cap and the capsule body to achieve preliminary pressing of the capsule; in addition, when the first capsule transport rack 521 and the second capsule transport rack 523 are moved to the waste rejection mechanism 9, due to the presence of unqualified capsules, the first capsule transport rack 521 and the second capsule transport rack 523 cannot remain in a stacked state, and need to remain in a staggered or parallel state to better perform waste rejection, which can be achieved by adopting the above-mentioned technical solution.

[0035] like Figure 1 , Figure 2 , Fig.10 , Fig.11The capsules in the feeding mechanism 2 shown are input through the capsule input channel 231, and as the slider moves longitudinally on the longitudinal guide rod 211, the capsule input channel 231 is connected with the capsule output channel 241. Thereafter, under the action of the capsule feeding device 232, the capsule is transferred from the capsule input channel 231 to the capsule output channel 241. Since the capsule input block 23 and the ejection mechanism 25 slide synchronously through the linkage device 26, the longitudinal movement of the longitudinal slider 212 and the lateral movement of the lateral slider 252 can be performed synchronously, that is, the lateral When the slider 252 moves backward, the longitudinal slider 212 moves downward to transfer the capsule from the capsule input channel 231 to the capsule output channel 241. Thereafter, the longitudinal slider 212 resets upward and the transverse slider 252 moves forward, and the push-out block 253 pushes the capsule from the capsule output channel 241 to the end of the capsule output channel 241 laterally. The cycle is repeated, and then the longitudinal slider 212 moves downward to drive the push-in block 27 to move downward to push the capsule at the end of the capsule output channel 241 into the first capsule transport assembly 52, thereby greatly improving production efficiency. The rotating shaft 261 of the linkage device 26 is inserted into the rotating bearing 213 on the feed rack 21. The rotating shaft 261 and the sleeve 262 rotate relatively quickly. Through the three swing arms radially extending from the sleeve 262, the first swing arm 263 is hinged to the longitudinal slider 212, the second swing arm 264 is hinged to the transverse slider 252, and is connected to the driving device through the third swing arm 265. The driving device only needs to move the third swing arm 265 longitudinally to drive the reciprocating motion of the first swing arm 263 and the second swing arm 264, which is convenient and quick.

[0036] like Figure 1 , Figure 2 , Fig.12 A blanking mechanism 4 is provided between the filling mechanism 3 and the rejecting mechanism 9 shown in the figure. The medicine enters the blanking input channel 431 on the blanking input block 43 through the blanking bin 42. The blanking control mechanism 44 controls the medicine in the blanking input channel 431 to enter the capsule in a quantitative and orderly manner through the opening 413 on the second fixed plate 412, thereby ensuring that the content of mixed medicines in the capsule remains consistent.

[0037] like Figure 1 , Figure 2 , Fig.17 , Fig.18A detection mechanism 8 is also provided between the feeding mechanism 2 and the filling mechanism 3 shown, and a waste rejection mechanism 9 is also provided between the filling mechanism 3 and the pressing mechanism 11. The detection mechanism 8 is connected to the waste rejection mechanism 9 by signal. The detection mechanism 8 detects whether the capsule has entered the turntable mechanism 5 or whether the position is correct. The sensor on the detection frame 81 can detect the capsule in the first capsule transport and placement assembly 52, and then transmits the detection signal to the waste rejection mechanism 9. The waste rejection frame 91 of the waste rejection mechanism 9 is connected to the pneumatic components, so that the waste capsule can be rejected by the suction force generated by the suction port 92. The push rod 93 drives the ejector pin 94 to push the waste capsule toward the suction port 92, so that the waste capsule can be rejected more accurately and effectively, thereby improving the working effectiveness and stability of the waste rejection mechanism 9, and there will be no missed rejection phenomenon, so as to achieve accurate rejection of waste.

[0038] like Figure 1 , Figure 2 , Figures 13 to 16 The shown filling mechanism 3 is provided with a rotating driving mechanism 36. The rotating driving mechanism 36 drives the rotating shaft 34 to rotate, which can first make the liquid guide groove 331 on the rotating shaft 34 communicate with the liquid inlet interface 321 on the pump body 32. At this time, the piston rod 33 is pulled out under the drive of the lifting driving mechanism 35, and the liquid medicine can be sucked into the inner cavity of the pump body 32 through the liquid inlet interface 321. Then, the rotating driving mechanism 36 drives the rotating shaft 34 to rotate in the opposite direction, so that the liquid guide groove 331 on the rotating shaft 34 is communicated with the liquid outlet interface 322 on the pump body 32. At this time, the piston rod 33 is plugged inward under the drive of the lifting driving mechanism 35, and the previously sucked liquid medicine can be squeezed out through the liquid outlet interface 322, so that the operation of adding liquid medicine into the capsule can be fully automated through the liquid adding output pipe.

[0039] like Figure 1 , Figure 2 , Fig.19 A control panel 12 is provided above the machine body 1 shown. The control panel 12 integrates a display screen 121, control buttons 122 and a control knob 123, so that the operator can intuitively and quickly adjust the machine parameters and monitor the operating status, thereby optimizing the human-machine interaction interface. In addition, the hinged design of the control panel 12 increases the flexibility of use, allowing the panel position to be adjusted according to the needs of the operator, and is also more convenient during maintenance and cleaning. The real-time data and diagnostic information displayed on the display screen 121 improves the intelligence level of the machine, allowing the operator to understand the machine status in a timely manner and make corresponding adjustments, thereby improving production efficiency and safety.
