Referring to fig. 1 to 9, a full-automatic vacuum plastic packaging machine for medical reagent plates in this embodiment includes a machine body 00, an electric cabinet 01, an operation panel 02, a reagent plate feeding unit 1, a drying agent feeding unit 2, a packaging bag feeding unit 3, a bag opening conveying unit 4, a material pushing and bagging unit 5, and a vacuum-pumping thermal plastic packaging unit 6. The raw material reagent plate 100, the desiccant 200 and the packaging bag 300 need to be manually operated and are respectively placed in the reagent plate bin 111, the desiccant driving module 211 and the packaging bag bin 34, wherein the reagent plate is cuboid and is flatly placed in the reagent plate bin 111, the desiccant 200 is in a circular scroll shape, the axis is fixed on the shaft of the desiccant driving module 211, the packaging bag 300 is a rectangular hard plastic packaging bag, the square is stacked in the packaging bag bin 34, after the preparation work is completed, the machine is started through the operation panel 02, and the machine starts to operate. The whole process from feeding the reagent plate to the drying agent, then packaging into the packaging bag, and vacuum-pumping and hot-sealing will be described in detail.

After the machine is started, referring to fig. 8 and fig. 1, the stepping mechanism 51 in the material pushing and bagging unit 5 starts to operate, and the material pushing stepping motor 511 in the material pushing and bagging unit 5 starts to drive the material pushing sliding table 512 to rotate, so as to drive the material pushing station 513 to move to the material loading end, namely the side of the reagent plate loading unit 1.

Referring to fig. 3, 8 and 1, the material receiving cylinder 121 is activated to drive the material receiving tray 122 to move upward, and the material receiving tray 122 passes through the circular hole in the material pushing station 513 to reach a position below the reagent plate bin 111 and to leave a gap for the reagent plates 100. Then the silo cylinder 112 is started to drive the silo claw 113 to move outwards, at the moment, the reagent plate 100 is influenced by gravity, falls downwards and is supported by the receiving tray 122, wherein the shape of the silo 111 of the reagent plate is consistent with the outer edge of the reagent plate 100, and the direction and the shape of the falling process are ensured to be within a controllable range.

Then the bin cylinder 112 is started to drive the bin claws 113 to move inwards to clamp the reagent plates 100, so that only one reagent plate 100 is supported on each receiving tray 122, then the receiving cylinder 121 is started to drive the receiving tray 122 to move downwards, in the moving process, the reagent plates 100 are in contact with the edge chamfer of the 513 pushing station, and the receiving tray 122 penetrates through the circular hole in the pushing station 513. At this time, the reagent plate falls down to the material pushing station 513 steadily under the influence of gravity and the edge chamfer of the material pushing station. So far, the reagent plate feeding process is completed.

Referring next to fig. 4 and 5, the desiccant driving module 211 is activated to rotate the auxiliary wheel 212, so as to drive the desiccant 200 to leave the strip from the desiccant roll and move the strip to the cutting module 213, and then the cutting module 213 is activated, wherein the sensor included in the cutting module 213 automatically recognizes the knife mark on the packing bag 200, and then the blade in the cutting module 213 cuts the desiccant 200 into small bags from the strip.

Referring next to fig. 4, 5, the desiccant 200 drops into the desiccant dispensing mechanism 22. When the cutting module 213 cuts a first cut, the movable guide seat 221 is positioned at the rightmost side, the drying agent 200 falling from the drying agent cutting mechanism 21 falls into the fixed conduit 224 at the leftmost side on the movable guide seat 221, and then the linear sliding table 222 is started to drive the movable guide seat 221 to move leftwards, and at the moment, the drying agent 200 falling from the drying agent cutting mechanism 21 falls into the second fixed conduit 224 at the left side on the movable guide seat 221. By analogy, in each round of packaging work, the desiccant feeding unit 2 cuts four desiccant 200 sachets and feeds the four desiccant 200 sachets into the four fixed pipes 224 respectively.

Referring to fig. 8, 4 and 1, the stepping mechanism 51 in the material pushing and bagging unit 5 starts to operate, the material pushing stepping motor 511 is started to drive the material pushing sliding table 512 to move, the material pushing station 513 is driven to move leftwards to a position right below the drying agent feeding unit 2, referring to fig. 4 and 5, the baffle cylinder 225 is started, and the drying agent 200 falls from the fixed conduit 224 to the upper surface of the reagent plate 200 in the material pushing station 513. So far, the dryer put-in process is completed.

Referring to fig. 6 and 2, the bag taking cylinder 31 in the packaging bag feeding unit 3 is started to drive the suction cup fixing frame 32 to move upwards, and drive the single suction cup taking module 33 to move upwards to the lower part of the packaging bag bin 34, and at this time, the suction cup in the bag taking suction cup module 33 is tightly attached to the packaging bag 300 located at the lowest part of the packaging bag bin 34. Then, the vacuum generator in the bag-taking suction cup module is started, so that negative pressure is generated in the suction cup in the bag-taking suction cup module 33, and the lower surface of the packaging bag 300 is tightly sucked by the suction cup in the bag-taking suction cup module 33 under the action of the pressure difference. The bag-removing cylinder 31 then performs repeated small up and down movements so that the packaging bag is separated from the other packaging bags 200 in the packaging bag bin 34.

Then, the bag taking cylinder 31 is started to drive the suction cup fixing frame 32 to move downwards, and the bag taking suction cup module 33 is driven to suck the packaging bag 300 to move downwards to the bagging station 35. At this time, the vacuum generator in the bag-taking suction cup module 33 continuously operates to ensure that the packaging bag 300 is horizontally placed at the bagging station 35, and the opening of the packaging bag 300 faces the material-pushing bagging unit 5.

Referring to fig. 7, 6 and 2, the blocking cylinder 46 of the bag opening and conveying unit 4 is started to drive the baffle plate 47 to retract upwards, and then the pneumatic sliding table 41 is started to drive the conveying table 42 to displace rightwards to a position right above the bag filling station 35. Subsequently, the grabbing cylinder 43 is started to drive the bag opening sucker fixing frame 44 to move downwards, and drive the bag opening sucker module 45 to move downwards until the sucker in the bag opening sucker module 45 is attached to the upper surface of the packaging bag 300 on the bagging station 35. Then, the vacuum generator in the bag opening suction cup module 45 is started, so that negative pressure is generated in the suction cup of the bag opening suction cup module 45, and the upper surface of the packaging bag 300 is tightly sucked by the suction cup in the bag opening suction cup module 45 under the action of the pressure difference. Subsequently, the grabbing cylinder 43 is started to drive the bag opening sucker fixing frame 44 to move upwards, and drive the bag opening sucker module 45 to move upwards. At this time, the bag-taking suction-cup module 33 and the bag-opening suction-cup module 45 are simultaneously operated, so that the upper and lower surfaces of the packing bag 300 are opened, and the packing bag is changed from a substantially planar form to an open three-dimensional form.

Referring to fig. 8, 6, and 2, the stepping mechanism 51 in the material pushing and bagging unit 5 starts to operate, and the material pushing stepping motor 511 starts to drive the material pushing sliding table 512 to move, so as to drive the material pushing station 513 to move to the right in front of the bagging station 35 (right in the figure). The opening claw 524 of the bagging mechanism 52 in the pusher bagging unit 5 reaches the opening of the opened packaging bag 300. And then, bagging is started by a bagging mechanism 52 positioned in the material pushing and bagging unit 5, wherein a bagging cylinder 521 is started to drive a push rod connecting frame 522 to displace, so as to drive a push plate 523 to displace, at the moment, the reagent plate 100 and the drying agent 200 are positioned in the material pushing station 513, the push plate 523 is positioned behind the material pushing station (on the right side in the figure), and when the push plate 523 displaces, the reagent plate 100 and the drying agent are pushed to leave the material pushing station 513 together and enter a bagging station 35.

It should be added that, referring to fig. 8, fig. 6, and fig. 2, during the process that the pushing plate 523 pushes the reagent plate 100 and the drying agent 200 to displace, the edge of the reagent plate 100 touches the inside of the opening claw 524 of the bagging mechanism 52. The outer side of the opening supporting claw 524 is fixed on the outer side edge of the material pushing station 513 by a bearing, and under the force conduction action of the reagent plate 100, the opening supporting claw 524 generates a rotation motion, and the claw part is supported along with the displacement of the reagent plate. Since the opening claw 524 is located inside the packaging bag 300 at this time under a series of actions of the pushing stepping motor 511, the claw part of the opening claw 524 contacts with the inner edge of the packaging bag 300 in the opening process and opens the packaging bag, the shape of the opened packaging bag 300 is changed from the original irregular opening to the opening with the same shape as the reagent plate 100, and the size of the opening is slightly larger than the reagent plate 100. At the same time, the reagent plate 100 and the desiccant 200 enter the inside of the package 300 as the mouth of the package is opened. The design and application of the structure ensure the smooth bagging of the reagent plate 100, and avoid the difficult problem that the reagent plate 100 is large and is difficult to automatically bag because the bag opening is too small. Subsequently, as the reagent plate 100 completely enters the packaging bag 300, the force applied by the reagent plate 100 to the edge of the opening claw 524 is completely removed, the spring 525 located on the opening claw 524 is deformed by the force generated by the opening claw 524, and after the force is removed, the opening claw is restored to the original shape by the elastic force generated by the spring 525. The design and the application enable the claw part of the opening supporting claw to be retracted, and guarantee that the opening supporting claw 524 can smoothly extend into the packaging bag 300 in the next packaging process. Subsequently, the bag-taking suction cup module 33 in the packaging bag feeding unit 3 stops sucking the lower surface of the packaging bag 300, and the packaging bag 300 is suspended in a half-empty state under the suction force of the bag-opening suction cup module 45 in the material-pushing and bagging unit 5, so far, the reagent plate bagging process is completed.

Next, referring to fig. 7, 9, and 2, the blocking cylinder 46 in the bag opening conveying unit 4 is activated, the blocking plate 47 is brought down, and then the pneumatic slide table 41 is activated. The conveying table 42 is driven to move leftwards to the position above the sealing station 63, then the bag opening sucker module 45 stops sucking the upper surface of the packaging bag 300, the packaging bag 300 falls onto the sealing station 63 under the action of gravity, and at the moment, under the action of the chamfering positioning groove of the sealing station 63, the packaging bag slides to the specified position of the sealing station 63.

Referring to fig. 7 and 6, the blocking cylinder 46 in the bag opening transfer unit 4 is activated to lift the shutter 47, and then the pneumatic slide table 41 is activated. Driving the conveying table 42 to move rightwards to the position right above the bagging station 35. At this time, the bag opening and conveying unit 4 leaves the vacuum heat sealing unit 6 and cooperates with other units to carry out the next round of bagging.

Referring next to fig. 9 and 10, the downward air cylinder 61 in the vacuuming thermoplastic sealing unit 6 is activated to displace the sealing cover 62 downward until the sealing strip at the edge of the sealing cover 62 completely fits the sealing station 63. The reagent plate and the package containing the desiccant are completely wrapped by the sealing cover 62 at the sealing station 63. The vacuum nozzle 64 is then activated to create a large negative pressure that is simultaneously created inside the sealing lid 62 by the vacuum nozzle 66. At the same time, the sealing cylinder 65 is actuated to displace the heat seal 66 downward to press the mouth of the bag 300 downward, but with a thread gap remaining. At this time, since the initial state of the inside of the packaging bag 300 is still at the atmospheric pressure, the air inside the packaging bag 300 is discharged from the gap due to the air pressure difference since the air pressure outside the packaging bag is rapidly decreased, and the inside of the packaging bag 300 is in a form similar to a vacuum at this time.

Referring to fig. 9, 10, 7 and 2, the heat sealing strip 66 is powered on to generate a large amount of heat, the mouth of the packaging bag 300 is melted instantaneously under the action of high temperature, at this time, the heat sealing strip 66 is powered off, the upper surface and the lower surface of the mouth of the packaging bag 300 are rapidly cooled and tightly bonded together, and then the sealing cylinder 65 and the pressing cylinder 61 are started to drive the heat sealing strip 66 and the sealing cover 62 to be lifted. Subsequently, the baffle plate 47 of the bag opening and conveying unit 4 moves along with the next displacement, the packaged finished product is pushed away from the sealing station 63, and the reagent plate 100, the drying agent 200 and the packaging bag 300 are packaged into the finished product after a series of processes such as feeding, bagging, vacuumizing, hot plastic packaging and the like, so that the automation of the processes is realized, the production efficiency and the yield are greatly improved, and the labor cost and the error rate are reduced.
