Description

Technical Field

[0001] The present application relates to the technical field of drug packaging equipment, and in particular to a fully automatic four-side-sealed multi-row granule packaging machine. Background Art

[0002] After the production of medicines is completed, they need to be packaged and sealed by a packaging machine to facilitate transportation and sale. When packaging pill particles, in order to facilitate patients to take the medicine in a fixed amount, the medicine needs to be measured first, and then the fixed amount of medicine is packaged in a packaging bag made of plastic film.

[0003] When the pills are packaged and encapsulated, the pills are generally placed in a barrel first, and then the feed pipe is opened, and the pills are measured by controlling the connection time of the feed pipe. If a machine failure occurs or pills are not added to the barrel in time, the amount of the packaged pills may not be consistent with the standard amount.

[0004] At present, after packaging and sealing, the packaged drugs are generally weighed to determine whether the amount of the packaged drugs is the standard value. If there is too much or too little, rework and repackaging are required, which causes inconvenience to the packaging and sealing of the drugs. Summary of the invention

[0005] In order to improve the convenience of drug packaging and packaging, the present application provides a fully automatic four-side sealing multi-row granule packaging machine.

[0006] The present application provides a fully automatic four-side-sealed multi-row granule packaging machine, which adopts the following technical solution:

[0007] A fully automatic four-side-sealed multi-row granule packaging machine comprises a frame, a material storage box, a material discharge assembly, a film supply assembly, a heat sealing assembly and a control assembly; the material storage box is fixedly arranged on the frame, and the material storage box is a top-opening structure; a material discharge pipe is connected to the bottom of the material storage box; the material discharge assembly comprises a material discharge tray and a first motor; the material discharge tray is horizontally arranged and located at the bottom of the material discharge pipe, and a plurality of first material discharge holes are opened on the material discharge tray along its circumference, and the first material discharge hole can just accommodate one pill particle; a mounting plate is fixedly arranged on the frame, and the mounting plate is located at the bottom of the material discharge tray, and a plurality of first material discharge holes are opened on the mounting plate along the circumference of the material discharge tray a second feed hole, the second feed hole corresponding to the first feed hole one by one; the first motor is fixedly arranged on the mounting plate, the first motor is used to drive the feed tray to rotate, and when the feed tray rotates, the first feed hole can be connected with the feed pipe; the film supply assembly is arranged on the frame, and the film supply assembly is used to convey the rolled plastic film to the bottom of the second feed hole; the heat sealing assembly is arranged on the frame, and is used to heat seal the plastic film to form a closed packaging bag with the plastic film; the control assembly is arranged on the frame, and the control assembly is used to control the connection state of the bottom of the first feed hole.

[0008] By adopting the above technical solution, when packaging and sealing the pill particles, the operator first uses the film supply component to convey the plastic film to the bottom of the second feeding hole, and uses the heat sealing component to heat-seal the plastic film to form a packaging bag with an open top. The pill particles are then placed in the storage box, and the first motor is used to drive the feeding tray to rotate. During the rotation process, the feeding tube is successively connected with the plurality of first feeding holes, and the pill particles in the storage box will enter the first feeding hole through the feeding tube. At this time, under the action of the control component, the bottom of the first feeding hole is in a disconnected state. The control component controls the bottom of the first feeding hole to be connected until all the first feeding holes are filled with pill particles. The pill particles fall downward under the action of their own gravity and fall into the packaging bag with an open top formed by the plastic film through the second feeding hole. The packaging bag containing the pill particles is then sealed by the heat sealing component to form a packaging bag structure with four sides sealed, and a packaging bag with an open top structure is formed above the sealed packaging bag. At the same time, the control component disconnects the bottom of the first feeding hole again, so that the subsequent packaging and packaging of the pill particles can continue.

[0009] The control component is used to control the connectivity state of the bottom of the first discharge hole. Only when pill particles are placed in all the first discharge holes, the bottom of the first discharge holes will be connected, and the pill particles will be discharged through the second discharge hole, thereby ensuring that the amount of packaged and sealed pill particles is the same as the standard amount, and there is no need to weigh the packaged and sealed drugs subsequently, thereby avoiding the need to re-measure and re-package the packaged and sealed drugs, thereby improving the convenience of drug packaging.

[0010] Optionally, the control assembly includes a control ring, a sun ring, a planetary gear, a coil spring and an adjusting component; the control ring is coaxially arranged at the bottom of the discharge tray and is rotatably connected to the discharge tray, and an inner gear ring is arranged on the control ring; the control ring is evenly provided with a plurality of third discharge holes along its own circumference, and the third discharge holes correspond one-to-one to the first discharge holes; the sun ring is coaxially fixedly arranged at the bottom of the discharge tray, and an outer gear ring is arranged on the sun ring; the planetary gear is rotatably arranged on the mounting plate, and an outer gear ring is arranged on the planetary gear; the coil spring is sleeved on the sun ring, and both ends of the coil spring are fixedly connected to the sun ring and the control ring respectively; the adjusting component is arranged on the mounting plate, and the adjusting component is used to adjust the meshing state between the planetary gear and the control ring and the sun ring.

[0011] By adopting the above technical solution, in the process of packaging and encapsulating the pill particles, when there are no pill particles placed in the first feeding hole, under the action of the adjusting component, the planetary gear is not meshed with the control ring and the sun ring. At this time, the first motor drives the feeding tray to rotate, and under the action of the coil spring, the control ring rotates together with the feeding tray. At this time, the third feeding hole is in a misaligned state with the first feeding hole, and the control ring makes the bottom of the first feeding hole in a disconnected state. When pill particles are placed in all the first feeding holes, under the action of the adjusting component, the planetary gear is meshed with the control ring and the sun ring. The control ring, the sun ring, the planetary gear and the mounting plate constitute a planetary gear set. When the motor drives the feeding tray to rotate, the sun ring rotates with the feeding tray. The sun ring drives the control ring to rotate through the planetary gear, and the rotation direction of the control ring is opposite to the rotation direction of the feeding tray, so that the control ring and the feeding tray rotate relative to each other until the first feeding hole is coaxially facing the third feeding hole, and the bottom of the first feeding hole is in a connected state.

[0012] When the pill particles fall downward from the second discharge hole, under the action of the adjusting component, the control ring and the sun ring are separated from the planetary gear, and under the action of the coil spring, the control ring and the discharge plate rotate relative to each other and reset, so that the first discharge hole and the third discharge hole are misaligned again. At this time, the bottom of the first discharge hole becomes disconnected again, thereby realizing precise control of the first discharge hole.

[0013] Optionally, the adjusting component includes a connecting column, a rotating shaft and a spring; the connecting column is located at the bottom of the discharge tray, and the connecting column is coaxially fixedly connected to the output shaft of the first motor; a mounting groove is coaxially opened on the connecting column; one end of the rotating shaft is coaxially arranged in the mounting groove and is slidably connected to the connecting column, and the other end is coaxially fixedly connected to the discharge tray; the spring is located in the mounting groove, and its two ends are respectively fixedly connected to the connecting column and the rotating shaft.

[0014] By adopting the above technical solution, when the pill particles are packaged and sealed, as the pill particles in the storage box enter the first discharge hole, the pressure on the spring gradually increases, the compressed length of the spring gradually decreases, the rotating shaft drives the discharge plate to slide downward in the vertical direction, and the discharge plate drives the control ring and the sun ring to move downward in the vertical direction. When there are no pill particles placed in the first discharge hole, the pressure on the spring does not reach the preset value, so that the compression amount of the spring is small, the distance that the rotating shaft slides downward relative to the connecting column is small, the distance that the discharge plate drives the sun ring and the control ring to slide downward is small, and the planetary gear cannot engage with the sun ring and the control ring.

[0015] When pill particles are placed in all the first feed holes, the pressure on the spring reaches the preset value, so that the compression of the spring reaches the maximum value, the distance the rotating shaft slides downward relative to the connecting column reaches the maximum value, and the feed plate drives the sun ring and the control ring to slide downward to the maximum value, and the planetary gear engages with the sun ring and the control ring, thereby realizing the control of the meshing state between the planetary gear, the control ring and the sun ring.

[0016] Optionally, the film supply assembly is provided with two groups, and is respectively located on both sides of the unloading tray, the film supply assembly includes a unwinding roller, a driving roller, a gear and a second motor; the unwinding roller and the driving roller are both rotatably arranged on the frame; the unwinding roller is used to install the plastic film roll; there are two driving rollers, and one end of the plastic film is located between the two driving rollers; there are two gears, and they correspond to the driving rollers one by one, the gears are coaxially fixedly connected to the driving rollers, and the two gears are meshed with each other; the second motor is fixedly arranged on the frame, and the second motor is used to drive one of the gears to rotate.

[0017] By adopting the above technical solution, when packaging the pill particles, the operator fixes the plastic film roll on the unwinding roller, and then uses the second motor to drive one of the gears to rotate, thereby driving the other gear to rotate in the opposite direction. The two gears drive the two driving rollers to rotate respectively, and the rotation directions of the two driving rollers are opposite. Under the friction force of the driving roller, the plastic film roll on the unwinding roller is unwound, and moves downward to the bottom of the second feeding hole under the weight of the plastic film itself.

[0018] Optionally, the heat sealing assembly includes a back plate, a U-shaped heat pressing plate and a first electric push rod; the back plate and the U-shaped heat pressing plate are respectively located on both sides of the unloading tray, and the back plate is fixedly arranged on the frame; the U-shaped heat pressing plate is used to heat-press and seal the plastic film to form a four-side sealed packaging bag; the first electric push rod is fixedly arranged on the frame, and the first electric push rod is used to drive the U-shaped heat pressing plate to move.

[0019] By adopting the above technical solution, when the pill particles are packaged and sealed, the first electric push rod is used to drive the U-shaped hot pressing plate to move towards the back plate, so that the two layers of plastic film between the U-shaped hot pressing plate and the back plate are hot-pressed together to form a packaging bag with an open top structure. After the drug particles fall from the bottom of the second feeding hole, they will fall into the packaging bag, and then the film supply assembly is used to move the plastic film and the packaging bag downward until the bottom of the U-shaped hot pressing plate is located at the top of the packaging bag. At this time, the first electric push rod is started, driving the U-shaped hot pressing plate to move towards the back plate, thereby sealing the packaging bag containing the pill particles to form a packaging bag structure with four sides sealed, and forming a packaging bag with an open top structure above the sealed packaging bag.

[0020] Optionally, a detection component is provided on the frame, and the detection component includes a displacement sensor and a controller; the displacement sensor is fixedly arranged in the mounting groove, and the displacement sensor is used to detect the distance information between itself and the rotating shaft, and convert it into a distance signal and input it into the controller, and the controller is fixedly arranged on the frame, and the controller is electrically connected to the first electric push rod and the second motor, and the controller is used to receive the distance signal transmitted by the displacement sensor, and control the working status of the first electric push rod and the second motor.

[0021] By adopting the above technical scheme, during the process of packing and packaging the pill particles, the displacement sensor detects the distance information between itself and the rotating shaft. When pill particles are placed in all the first feeding holes, so that the compression spring of the rotating shaft slides downward to the maximum distance, the controller controls the second motor and the first electric push rod to start with a delay, that is, when the pill particles in the first feeding hole fall into the packaging bag through the third feeding hole and the second feeding hole, the second motor is started to move the packaging bag containing the pill particles downward until the bottom of the U-shaped hot pressing plate is located at the top of the packaging bag. At this time, the first electric push rod is started, driving the U-shaped hot pressing plate to move toward the direction close to the back plate, thereby sealing the packaging bag containing the pill particles to form a packaging bag structure with four sides sealed, and forming a packaging bag with an open top structure above the sealed packaging bag, thereby realizing the automation of packaging and packaging of drug particles.

[0022] Optionally, a cutting assembly is provided on the frame, and the cutting assembly includes a cutter and a second electric push rod; the cutter is located on the side of the unloading tray away from the back plate, and is located at the bottom of the U-shaped hot pressing plate; the second electric push rod is fixedly provided on the frame, and the second electric push rod is used to drive the cutter to move; the second electric push rod is electrically connected to the controller, and the controller is also used to control the working state of the second electric push rod.

[0023] By adopting the above technical solution, during the process of packing and packaging the pill particles, the displacement sensor detects the distance information between itself and the rotating shaft. When pill particles are placed in all the first feeding holes, the compression spring of the rotating shaft slides downward to the maximum distance, and the controller controls the second electric push rod to start with a delay, that is, when the first electric push rod drives the U-shaped hot pressing plate to seal the packaging bag containing the pill particles, the second electric push rod starts, and the second electric push rod drives the cutter to move toward the back plate, so that the packaging bag that has just been sealed is cut and separated from the packaging bag at the bottom, and the packaging bag at the bottom of the packaging bag that has just been sealed falls downward, then the packaging and packaging of the medicine is completed, and the automatic cutting of the packaged and packaged packaging bags is realized.

[0024] Optionally, the detection component further includes a buzzer, which is fixedly mounted on the rack and used to emit an alarm sound. The buzzer is electrically connected to the controller, and the controller is also used to control the working state of the buzzer.

[0025] By adopting the above technical solution, when the controller does not receive the displacement signal transmitted by the displacement sensor for a certain period of time, it means that the pill particles in the storage box are insufficient or the equipment fails. At this time, the controller controls the buzzer to sound an alarm to remind the operator to replenish the pill particles in time and repair the equipment. There is no need for the operator to observe all the time, thereby improving the convenience of packaging the pill particles.

[0026] In summary, the present application includes at least one of the following beneficial technical effects:

[0027] By setting a control component, the connection state of the bottom of the first feeding hole is controlled. Only when pill particles are placed in all the first feeding holes, the bottom of the first feeding holes will be connected, and the pill particles will be fed through the second feeding hole, ensuring that the amount of the packaged and sealed pill particles is the same as the standard amount, and there is no need to weigh the packaged and sealed drugs later, thereby avoiding the need to re-measure and re-package the packaged and sealed drugs, and improving the convenience of drug packaging;

[0028] By setting up a detection component, a displacement sensor is used to detect the distance information between itself and the rotating shaft. When pill particles are placed in all the first feeding holes, the rotating shaft compression spring slides downward to the maximum distance, and the controller controls the second motor and the first electric push rod to start with a delay, thereby realizing automatic supply of plastic film, automatic heat sealing of plastic film and automatic cutting of packaging bags, which greatly improves the automation degree of drug particle packaging, thereby improving the convenience of drug packaging;

[0029] By setting a buzzer, when the controller does not receive the displacement signal transmitted by the displacement sensor for a certain period of time, it means that there are insufficient pill particles in the storage box or the equipment fails. At this time, the controller controls the buzzer to sound an alarm to remind the operator to replenish the pill particles in time and repair the equipment. There is no need for the operator to observe all the time, thereby improving the convenience of packaging the pill particles. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The following is combined with Figure 1-7 This application is described in further detail.

[0047] The present application embodiment discloses a fully automatic four-side sealed multi-row granule packaging machine. Figure 1 and Figure 2 The fully automatic four-side-sealed multi-row granule packaging machine comprises a frame 1 and a storage box 2. The storage box 2 is fixedly arranged on the top of the frame 1, and the storage box 2 is a top-opening structure. A feeding pipe 21 is vertically arranged at the bottom of the storage box 2, and the feeding pipe 21 is connected to the inside of the storage box 2. The bottom of the storage box 2 is a constricted structure along the direction close to the feeding pipe 21.

[0048] Reference Figure 2 and Figure 3 A feeding assembly 3 is arranged on the frame 1, and the feeding assembly 3 includes a feeding tray 31. The feeding tray 31 is horizontally arranged at the bottom of the feeding tube 21, and a plurality of first feeding holes 311 are evenly opened along the circumference of the feeding tray 31, and the first feeding holes 311 can just accommodate one pill particle, and the number of the first feeding holes 311 is the same as the number of pill particles encapsulated in each package of medicine.

[0049] Reference Figure 3 and Figure 4 A mounting plate 11 is fixedly provided on the frame 1, and the mounting plate 11 is horizontally arranged at the bottom of the unloading tray 31. A plurality of second unloading holes 111 are evenly opened on the mounting plate 11 along the circumference of the unloading tray 31, and the second unloading holes 111 correspond to the first unloading holes 311 one by one.

[0050] The material discharge assembly 3 further includes a first motor 32, which is fixedly arranged at the bottom of the mounting plate 11, and the output shaft of the first motor 32 is coaxially arranged with the material discharge tray 31, and the output shaft of the first motor 32 is connected to the material discharge tray 31, and the first motor 32 is used to drive the material discharge tray 31 to rotate. During the rotation of the material discharge tray 31, the first material discharge hole 311 can be located at the bottom of the material discharge pipe 21, and the two are connected to each other.

[0051] Reference Figure 5 and Figure 6 , a control assembly 6 is arranged on the frame 1, and the control assembly 6 includes a control ring 61, a sun ring 62, a planetary gear 63, a coil spring 64 and an adjusting component 65.

The control ring 61 is rotatably connected with the feed tray 31, and the rotation axis is the same as the rotation axis of the feed tray 31. An inner gear ring is arranged on the inner side wall of the control ring 61. A plurality of third feed holes 611 are evenly opened on the control ring 61 along its own circumference, and the third feed holes 611 correspond to the first feed holes 311 one by one. The sun ring 62 is located at the bottom of the feed tray 31, and is coaxially fixedly connected with the feed tray 31, and an outer gear ring is arranged on the sun ring 62. The planetary gear 63 is rotatably arranged on the mounting plate 11, and an outer gear ring is arranged on the planetary gear 63. The outer gear ring of the planetary gear 63 is adapted to the outer gear ring on the sun ring 62 and the inner gear ring on the control ring 61. The coil spring 64 is sleeved on the sun ring 62 , and one end of the coil spring 64 located on the inner ring is fixedly connected to the sun ring 62 , and one end of the coil spring 64 located on the outer ring is fixedly connected to the control ring 61 .

[0052] The adjusting component 65 includes a connecting column 651, a rotating shaft 652 and a spring 653. The connecting column 651 is located at the bottom of the unloading tray 31, and the bottom end of the connecting column 651 is penetrated on the mounting plate 11. The connecting column 651 is coaxially arranged with the unloading tray 31, and the bottom end of the connecting column 651 is coaxially fixedly connected with the output shaft of the first motor 32. A mounting groove is coaxially provided at the top of the connecting column 651. A slide groove is provided on the connecting column 651, and the length direction of the slide groove is parallel to the length direction of the connecting column 651, and the slide groove is connected with the mounting groove. The bottom end of the rotating shaft 652 is coaxially arranged in the mounting groove, and a slider is fixedly arranged on the rotating shaft 652, and the slider is adapted to the slide groove. The slider is slidably arranged in the slide groove, and the sliding axis is arranged along the length direction of the slide groove. The top end of the rotating shaft 652 is coaxially fixedly connected with the unloading tray 31. The spring 653 is located in the installation groove, and the length direction of the spring 653 is the same as the length direction of the connecting column 651 . Two ends of the spring 653 are fixedly connected to the connecting column 651 and the rotating shaft 652 respectively.

[0053] In the initial state, the spring 653 and the coil spring 64 are both in a normal state. At this time, the top wall of the discharge plate 31 abuts against the bottom end of the discharge tube 21, the first discharge hole 311 is arranged opposite to the discharge tube 21, the first discharge hole 311 is connected with the discharge tube 21, the second discharge hole 111 and the third discharge hole 611 are offset from the first discharge hole 311, and the sun ring 62 and the control ring 61 are not engaged with the planetary gear 63.

[0054] When packing and packaging the pill particles, the operator first places the pill particles in the storage box 2, and then starts the first motor 32. The first motor 32 drives the connecting column 651 and the rotating shaft 652 to rotate, thereby driving the discharge plate 31, the sun ring 62 and the control ring 61 to rotate together. During the rotation, the discharge pipe 21 is successively connected with several first discharge holes 311, and the pill particles in the storage box 2 will enter the first discharge hole 311 through the discharge pipe 21.

[0055] As the pill particles in the storage box 2 enter the first discharge hole 311, the pressure on the spring 653 gradually increases, and the compressed length of the spring 653 gradually decreases. The rotating shaft 652 drives the discharge tray 31 to slide downward in the vertical direction, and the discharge tray 31 drives the control ring 61 and the sun ring 62 to move downward in the vertical direction until pill particles are placed in all the first discharge holes 311.

[0056] When pill particles are placed in all the first discharge holes 311, the inner gear ring on the control ring 61 and the outer gear ring on the sun ring 62 are meshed with the outer gear ring on the planetary gear 63. The control ring 61, the sun ring 62, the planetary gear 63 and the mounting plate 11 constitute a planetary gear set, in which the sun ring 62 is the input power and the control ring 61 is the output power. When the motor drives the discharge tray 31 to rotate through the connecting column 651 and the rotating shaft 652, the sun ring 62 rotates with the discharge tray 31. The sun ring 62 rotates through the sun ring 62. The planetary gear 63 drives the control ring 61 to rotate, and the rotation direction of the control ring 61 is opposite to that of the feeding tray 31, so that the control ring 61 and the feeding tray 31 rotate relative to each other until the first feeding hole 311 and the third feeding hole 611 are coaxially opposite to each other. At this time, the second feeding hole 111 is also coaxially opposite to the first feeding hole 311 and the third feeding hole 611, and the pill particles in the first feeding hole 311 fall to the bottom of the mounting plate 11 through the third feeding hole 611 and the second feeding hole 111. When the control ring 61 and the feeding tray 31 rotate relative to each other, the coil spring 64 is compressed.

[0057] After the pill particles fall, due to the loss of pressure from the pill particles, the rotating shaft 652 slides upward under the elastic force of the spring 653, thereby driving the discharge tray 31, the control ring 61 and the sun ring 62 to slide upward, so that the control ring 61 and the sun ring 62 are separated from the planetary gear 63. Under the action of the coil spring 64, the control ring 61 and the discharge tray 31 rotate relative to each other and reset, so that the first discharge hole 311 and the second discharge hole 111 and the third discharge hole 611 are misaligned again.

[0058] It should be noted that when pill particles are placed in all the first feeding holes 311, the feeding tray 31 moves downward by the maximum distance, which is smaller than the diameter of the pill particles to be packaged, thereby preventing the pill particles from leaking out of the gap between the feeding tube 21 and the feeding tray 31. At the same time, the distance between the control ring 61 and the mounting plate 11 is also smaller than the diameter of the pill particles to be packaged, thereby preventing the pill particles from leaking out of the gap between the control ring 61 and the mounting plate 11.

[0059] Reference Figure 4 In order to ensure the speed of filling the pill particles into the first discharge hole 311, multiple discharge pipes 21 can be set along the circumference of the discharge plate 31. In this embodiment, two discharge pipes 21 are set, and they are symmetrically arranged on both sides of the rotating shaft 652. The speed of filling the pill particles into the first discharge hole 311 is doubled, and when one of the discharge pipes 21 is blocked, the other discharge pipe 21 can still complete the filling operation.

The reel 41 is horizontally arranged on the frame 1 and is rotatably connected to the frame 1, and the rotation axis is horizontally arranged. The reel 41 is used to install the plastic film roll and unwind the plastic film. There are two driving rollers 42, and the two driving rollers 42 are arranged parallel to the reel 41, and are both rotatably arranged on the frame 1. The rotation axis of the driving roller 42 is parallel to the rotation axis of the reel 41, and one end of the plastic film is located between the two driving rollers 42. There are two gears 43, and they correspond to the driving rollers 42 one by one. The gears 43 are coaxially fixedly connected to the driving rollers 42, and the two gears 43 are meshed with each other. The second motor 44 is fixedly arranged on the frame 1, and the output shaft of the second motor 44 is coaxially fixedly connected to one of the gears 43.

[0061] In actual production, the unwinding roller 41 can be detachably arranged on the frame 1, so as to facilitate the replacement of the plastic film roll.

[0062] Reference Figure 5A heat sealing assembly 5 is arranged on the frame 1, and the heat sealing assembly 5 includes a back plate 51, a U-shaped hot pressing plate 52 and a first electric push rod 53. The back plate 51 is fixedly arranged on the frame 1, and the plane where the back plate 51 is located is arranged vertically. The U-shaped hot pressing plate 52 is located on the side of the unloading tray 31 away from the back plate 51, and the U-shaped hot pressing plate 52 is used to perform hot pressing and sealing on the plastic film so that the plastic film forms a four-side sealed packaging bag. The first electric push rod 53 is arranged horizontally, and the axis of the first electric push rod 53 is perpendicular to the back plate 51. The first electric push rod 53 is located on the side of the U-shaped hot pressing plate 52 away from the back plate 51. The fixed end of the first electric push rod 53 is fixedly connected to the frame 1, and the movable end of the first electric push rod 53 is fixedly connected to the U-shaped hot pressing plate 52.

[0063] Reference Figure 1 and Figure 6 , a detection assembly 7 is arranged on the frame 1, and the detection assembly 7 includes a displacement sensor 71, a buzzer 73 and a controller 72. The displacement sensor 71 is fixedly arranged in the mounting groove, and the displacement sensor 71 is used to detect the distance information between itself and the rotating shaft 652, and convert it into a distance signal to be input into the controller 72. The buzzer 73 is fixedly arranged on the frame 1, and the buzzer 73 is used to emit an alarm sound. The controller 72 is fixedly arranged on the frame 1, and the controller 72 is electrically connected to the displacement sensor 71, the buzzer 73, the first electric push rod 53 and the second motor 44. The controller 72 is used to receive the distance signal transmitted by the displacement sensor 71, and control the working state of the buzzer 73, the first electric push rod 53 and the second motor 44.

[0064] When packaging the pill particles, the operator first moves one end of the plastic film on both sides of the feed tray 31 to between the U-shaped hot press plate 52 and the back plate 51, and then starts the first electric push rod 53, which drives the U-shaped hot press plate 52 to move closer to the back plate 51, thereby hot-pressing the two layers of plastic film between the U-shaped hot press plate 52 and the back plate 51 together to form a packaging bag with an open top structure. When the pill particles in the first feed hole 311 fall to the bottom of the mounting plate 11 through the third feed hole 611 and the second feed hole 111, they will fall into the packaging bag.

[0065] When pill particles are placed in all the first feeding holes 311, so that the rotating shaft 652 compresses the spring 653 and slides downward to the maximum distance, the displacement sensor 71 inputs the detected distance between itself and the rotating shaft 652 into the controller 72, and the controller 72 controls the second motor 44 and the first electric push rod 53 to start with a delay, that is, when the pill particles in the first feeding hole 311 fall into the packaging bag through the third feeding hole 611 and the second feeding hole 111, the second motor 44 starts, and the second motor 44 drives one of the gears 43 to rotate, thereby driving the other gear 43 to rotate in the opposite direction, and the two gears 43 drive The two driving rollers 42 are rotated in opposite directions. Under the friction force of the driving rollers 42, the plastic film roll on the unwinding roller 41 is unwound. Under the gravity of the plastic film itself and the pill particles, the packaging bag containing the pill particles moves downward until the bottom of the U-shaped hot pressing plate 52 is located at the top of the packaging bag. At this time, the first electric push rod 53 is started, driving the U-shaped hot pressing plate 52 to move toward the back plate 51, thereby sealing the packaging bag containing the pill particles to form a packaging bag structure with four sides sealed, and forming a packaging bag with an open top structure above the sealed packaging bag.

[0066] When the controller 72 does not receive the displacement signal transmitted by the displacement sensor 71 for a certain period of time, it means that the pill particles in the storage box are insufficient or the equipment fails. At this time, the controller 72 controls the buzzer 73 to sound an alarm to remind the operator to replenish the pill particles in time and repair the equipment.

[0067] Reference Figure 5 The frame 1 is provided with a cutting assembly 8, which includes a cutter 81 and a second electric push rod 82. The cutter 81 is arranged horizontally, and the cutter 81 is located on the side of the unloading tray 31 away from the back plate 51. The cutter 81 is located at the bottom of the U-shaped hot pressing plate 52. The second electric push rod 82 is arranged horizontally, and the axis of the second electric push rod 82 is perpendicular to the back plate 51. The second electric push rod 82 is located on the side of the cutter 81 away from the back plate 51. The fixed end of the second electric push rod 82 is fixedly connected to the frame 1, and the movable end of the second electric push rod 82 is fixedly connected to the cutter 81. The second electric push rod 82 is electrically connected to the controller 72, and the controller 72 is also used to control the working state of the second electric push rod 82.

[0068] When pill particles are placed in all the first discharge holes 311, so that the rotating shaft 652 compresses the spring 653 and slides downward to the maximum distance, the displacement sensor 71 inputs the detected distance between itself and the rotating shaft 652 into the controller 72, and the controller 72 controls the second electric push rod 82 to start with a delay, that is, when the first electric push rod 53 drives the U-shaped hot pressing plate 52 to seal the packaging bag containing the pill particles, the second electric push rod 82 starts, and the second electric push rod 82 drives the cutter 81 to move toward the back plate 51, so that the packaging bag that has just been sealed is cut and separated from the packaging bag at the bottom thereof, and the packaging bag at the bottom of the packaging bag that has just been sealed falls downward, and the packaging and packaging of the medicine is completed.

[0069] Reference Figure 5 In some other embodiments, in order to ensure that the pill particles falling from the second discharge hole 111 can accurately fall into the packaging bag with the top opening structure formed by the two plastic films, a retaining ring 112 is installed at the bottom of the mounting plate 11, and the interior of the retaining ring 112 is a shrinking structure in the vertical downward direction. The film supply assembly 4 also includes a first limiting roller 45 and a second limiting roller 46, which are both rotatably arranged on the frame 1. The first limiting roller 45 is located on the side of the plastic film close to the retaining ring 112. The first limiting roller 45 is used to limit the plastic film to prevent the two plastic films from being adsorbed together. The second limiting roller 46 is located on the side of the plastic film away from the retaining ring 112. The second limiting roller 46 is used to limit the plastic film to ensure that the two plastic films are located between the U-shaped hot pressing plate 52 and the back plate 51.

[0070] The first limiting roller 45 is provided to prevent the two plastic films from being adsorbed together, and cooperates with the retaining ring 112 of the necking structure to ensure that the pill particles can fall into the packaging bag with a top opening structure formed by the two plastic films.

[0071] It should be noted that the technical solution adopted by the present invention can arbitrarily set up multiple groups, and the multiple groups do not interfere with each other and work independently. Compared with traditional linkage equipment, the present invention can still carry out the packaging operation of pill particles even if one of the groups fails.

[0072] The implementation principle of a fully automatic four-side-sealed multi-row granule packaging machine in the embodiment of the present application is:

[0073] When packaging the pill particles, the operator first moves one end of the plastic film on both sides of the discharge tray 31 to between the U-shaped hot pressing plate 52 and the back plate 51, and then starts the first electric push rod 53, which drives the U-shaped hot pressing plate 52 to move toward the back plate 51, thereby hot-pressing the two layers of plastic film between the U-shaped hot pressing plate 52 and the back plate 51 together to form a packaging bag with an open top structure.

[0074] Then, the operator places the pill particles in the storage box 2 and starts the first motor 32. The first motor 32 drives the connecting column 651 and the rotating shaft 652 to rotate, thereby driving the discharge tray 31, the sun ring 62 and the control ring 61 to rotate together. During the rotation, the discharge pipe 21 is successively connected with several first discharge holes 311, and the pill particles in the storage box 2 will enter the first discharge holes 311 through the discharge pipe 21. As the pill particles in the storage box 2 enter the first discharge holes 311, the pressure on the spring 653 gradually increases, and the compressed length of the spring 653 gradually decreases. The rotating shaft 652 drives the discharge tray 31 to slide downward in the vertical direction, and the discharge tray 31 drives the control ring 61 and the sun ring 62 to move downward in the vertical direction until pill particles are placed in all the first discharge holes 311.

[0075] When pill particles are placed in all the first feed holes 311, the feed tray 31, the rotating shaft 652, the control ring 61 and the sun ring 62 move downward to the maximum position, and the inner ring gear on the control ring 61 and the outer ring gear on the sun ring 62 are meshed with the outer ring gear on the planetary gear 63. When the motor drives the feed tray 31 to rotate, the sun ring 62 rotates with the feed tray 31, and the sun ring 62 drives the control ring 61 to rotate through the planetary gear 63, and the rotation direction of the control ring 61 is opposite to the rotation direction of the feed tray 31, so that the control ring 61 and the feed tray 31 rotate relative to each other until the first feed hole 311 is coaxially opposite to the third feed hole 611. At this time, the second feed hole 111 is also coaxially opposite to the first feed hole 311 and the third feed hole 611, and the pill particles in the first feed hole 311 fall to the bottom of the mounting plate 11 through the third feed hole 611 and the second feed hole 111.

[0076] When pill particles are placed in all the first feeding holes 311, so that the rotating shaft 652 compresses the spring 653 and slides downward to the maximum distance, the displacement sensor 71 inputs the detected distance between itself and the rotating shaft 652 into the controller 72, and the controller 72 controls the second motor 44, the first electric push rod 53 and the second electric push rod 82 to start with a delay, that is, when the pill particles in the first feeding hole 311 fall into the packaging bag through the third feeding hole 611 and the second feeding hole 111, the second motor 44 starts, and the second motor 44 drives one of the gears 43 to rotate, thereby driving the other gear 43 to rotate in the opposite direction, and the two gears 44 are turned on. 3 respectively drives the two driving rollers 42 to rotate, and the two driving rollers 42 rotate in opposite directions. Under the friction force of the driving rollers 42, the plastic film roll on the unwinding roller 41 is unwound. Under the gravity of the plastic film itself and the pill particles, the packaging bag containing the pill particles moves downward until the bottom of the U-shaped hot pressing plate 52 is located at the top of the packaging bag. At this time, the first electric push rod 53 is started, driving the U-shaped hot pressing plate 52 to move toward the direction close to the back plate 51, thereby sealing the packaging bag containing the pill particles to form a packaging bag structure with four sides sealed, and forming a packaging bag with an open top structure above the sealed packaging bag. At this time, the second electric push rod 82 is started, and the second electric push rod 82 drives the cutter 81 to move toward the direction close to the back plate 51, so that the packaging bag just sealed is cut and separated from the packaging bag at its bottom, and the packaging bag at the bottom of the packaging bag just sealed falls downward, and the packaging and packaging of the medicine is completed.

[0077] When the controller 72 does not receive the displacement signal transmitted by the displacement sensor 71 for a certain period of time, it means that the pill particles in the storage box are insufficient or the equipment fails. At this time, the controller 72 controls the buzzer 73 to sound an alarm to remind the operator to replenish the pill particles in time and repair the equipment.

[0078] When the control ring 61 and the feeding tray 31 rotate relative to each other, the coil spring 64 is compressed under the drive of the control ring 61. After the pill particles fall, due to the loss of the pressure of the pill particles, the rotating shaft 652 slides upward under the elastic force of the spring 653, thereby driving the feeding tray 31, the control ring 61 and the sun ring 62 to slide upward, so that the control ring 61 and the sun ring 62 are separated from the planetary gear 63. Under the action of the coil spring 64, the control ring 61 and the feeding tray 31 rotate relative to each other and reset, so that the first feeding hole 311 and the second feeding hole 111 and the third feeding hole 611 are misaligned again, and the reset is completed. Repeat the above process to continue to pack and package the pill particles.

[0079] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
