[0002] In order to facilitate transportation, medicinal materials are often sealed in bags. In order to protect the quality of medicinal materials and extend their shelf life, they are often sealed in vacuum packaging. When filling medicinal materials, it is often necessary to place the packaging bag on the corresponding placement rack, fix it, and then fill the medicinal materials. In order to better fix and limit, and at the same time avoid damage to the packaging bag and cause leakage of medicinal materials, the medicinal materials are often collected in a closed manner and by placing a collection frame underneath. However, leaked medicinal materials are not only difficult to collect, but when multiple medicinal materials need to be filled, the medicinal materials also need to be classified, which is extremely cumbersome. In order to reduce the occurrence of this situation, the staff often checks whether the packaging bag is damaged when fixing it on the placement rack. However, it should be noted that in order to allow consumers to better observe the medicinal materials in the packaging bag, the packaging bag often uses a transparent packaging bag, which increases the difficulty of inspection, and smaller holes are difficult to observe. Summary of the invention

Then, the electric telescopic rod is controlled to contract and drive the unloading barrel to move downward, pushing the heat sealer, so that the two heat sealers move away from each other, and the packaging bag loses the limit of the heat sealer. Then, after the vacuum heat-sealed packaging is completed, the packaging bag falls back into the limit barrel, and then the first multi-stage electric push rod is controlled to push the corresponding limit barrel to move downward close to the limit frame. Then, the staff sorts out the packaging bags in the limit barrel and selects the problematic packaging bags.

[0016] 3. The present invention determines whether there are any medicinal material fragments remaining in the waste barrel. When medicinal materials are found in the waste barrel, the staff takes out the corresponding waste barrel, removes the filter screen from the waste barrel, and then pours the medicinal materials into an external collection bucket. It should be noted that in the process of collecting medicinal materials in the above state, when the packaging bag is punctured by the medicinal materials, the medicinal materials therein will leak out, and the leaked medicinal materials need to be collected to avoid waste of medicinal materials, that is, the leaked medicinal materials are collected through the waste barrel.

DETAILED DESCRIPTION

[0029] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0030] Example 1

[0031] A convenient packaging bag placement rack, such as Figure 1-Figure 6 As shown, it includes a placement rack 1; it also includes a limiting rack 2, a second connecting plate 5, a first multi-stage electric push rod 6, a limiting cylinder 7, a second limiting plate 8, a sealing elastic cloth 9, a feeding cylinder 14, a translation component and an adjustment component; the placement rack 1 is fixedly connected to the limiting rack 2, and the limiting rack 2 is provided with sixteen symmetrically arranged first slide grooves; the limiting rack 2 is connected to the translation component; the translation component is connected to two symmetrically arranged second connecting plates 5, and each second connecting plate 5 is fixedly connected to eight equidistantly distributed first multi-stage electric push rods. The electric push rod 6 is a movable push rod 6; the telescopic ends of the two first multi-stage electric push rods 6 in each group are fixedly connected with five equally spaced limit cylinders 7; the five limit cylinders 7 in the same group are connected to each other; each limit cylinder 7 is fixedly connected with a second limit plate 8; each limit cylinder 7 is fixedly connected with two symmetrically arranged sealing elastic cloths 9; the limit frame 2 is connected with an adjusting component; the adjusting component is connected with five equally spaced discharge cylinders 14, and each discharge cylinder 14 is provided with two symmetrically arranged air exhaust ports 14001.

[0032] The translation assembly includes a first connecting plate 3 and a second multi-stage electric push rod 4; two symmetrically arranged first connecting plates 3 are fixedly connected to the limit frame 2; each first connecting plate 3 is fixedly connected to a second multi-stage electric push rod 4; the telescopic end of each second multi-stage electric push rod 4 is fixedly connected to the corresponding second connecting plate 5.

[0033] The adjustment assembly includes an electric slide rail 10, an electric slider 11, an electric telescopic rod 12 and a third connecting plate 13; two symmetrically arranged electric slide rails 10 are bolted to the limit frame 2; each electric slide rail 10 is slidably connected to the electric slider 11; each electric slider 11 is fixedly connected to the electric telescopic rod 12; the third connecting plate 13 is fixedly connected to the telescopic ends of all the electric telescopic rods 12; the third connecting plate 13 is fixedly connected to five unloading barrels 14.

[0034] A rubber structure is provided on the upper surface of the second limiting plate 8 to cooperate with the lower barrel 14 to clamp the packaging bag so that the packaging bag fits tightly with the second limiting plate 8 and the lower barrel 14 to enhance the fixing effect.

[0035] A limiting frame 14002 made of rubber material is fixedly connected to each unloading barrel 14, which is used to cooperate with the unloading barrel 14 to limit the packaging bag to enhance the sealing effect.

[0036] The limiting frame 14002 is configured to have a wedge-shaped structure that is smaller at the bottom and larger at the top, and is used to cooperate with the second limiting plate 8 to limit the packaging bag and enhance the sealing effect.

[0037] First, the staff uses the external bagging equipment to place the packaging bags one by one on the limiting cylinder 7, and flips the bag mouth of the packaging bag to cover the second limiting plate 8, controls the second multi-stage electric push rod 4 to push the second connecting plate 5 to move forward, and the second connecting plate 5 drives the first multi-stage electric push rod 6, the limiting cylinder 7, the second limiting plate 8 and the sealing elastic cloth 9 to move forward close to the discharge cylinder 14, and then controls the electric telescopic rod 12 to contract and drive the third connecting plate 13 to move downward, and then the third connecting plate 13 drives the discharge cylinder 14 to move downward close to and contact the second limiting plate 8, that is, the bag mouth of the packaging bag on the second limiting plate 8 is fixed by the discharge cylinder 14. The frame 14002 is set to have a wedge-shaped structure with a small bottom and a large top. First, the limit frame 14002 enters the second limit plate 8, and then the outer surface of the limit frame 14002 contacts the inner annular surface of the second limit plate 8. Since the second limit plate 8 is covered with a packaging bag, the outer surface of the limit frame 14002 squeezes the inner wall surface of the bag opening of the packaging bag, and cooperates with the second limit plate 8 to fix the packaging bag to enhance the blocking effect. Then the external air pump is controlled to run and absorb the air in the packaging bag through the exhaust port 14001. When there is damage on the packaging bag, that is, during this process, the air in the limit cylinder 7 and the second limit plate 8 is discharged through the exhaust port 14001 under the action of the external pump. That is, during this process, as the air in the limiting cylinder 7 and the second limiting plate 8 decreases, the sealing elastic fabric 9 will be sunken inward, that is, in this way, it can be judged whether the packaging bag is damaged, and the valve on the pipeline of the external conveying equipment on the corresponding unloading cylinder 14 is closed to avoid that when the medicinal materials are subsequently packaged through the packaging bag, the medicinal materials cannot be better sealed due to the damage of the packaging bag, thereby reducing the waste of medicinal materials. After completing the inspection of the packaging bag, the external air pump is controlled to operate, and air is injected into the packaging bag through the air suction port 14001 to make the packaging bag bulge, and then the external conveying equipment is used to convey the medicinal materials into the packaging bag through the unloading cylinder 14. After completing the filling of the medicinal materials, the electric The movable telescopic rod 12 pushes the third connecting plate 13 to move upward, and the third connecting plate 13 drives the discharge barrel 14 to move upward and out of the packaging bag. Then the electric slider 11 is controlled to slide backward on the electric slide rail 10, and the electric slider 11 drives the electric telescopic rod 12 to move backward. The electric telescopic rod 12 drives the third connecting plate 13 and the discharge barrel 14 to move to the top of the next group of limiting barrels 7. Then the staff manually seals and packages the medicinal materials, and then controls the first multi-stage electric push rod 6 to push the corresponding limiting barrel 7 to move downward. Then the staff takes out the damaged packaging bags without medicinal materials, and takes out the packaging bags with medicinal materials, and places them in the storage frame of the external device.

[0038] Example 2

[0039] On the basis of the above-mentioned embodiment 1, Figure 7-Figure 9As shown, it also includes a heat sealing component, which includes a fourth connecting plate 201, a spring telescopic rod 202, a fifth connecting plate 203, a heat sealer 204, a spring limiting rod 205 and a hook 206; each electric slider 11 is fixedly connected to a fourth connecting plate 201; each fourth connecting plate 201 is fixedly connected to two symmetrically arranged spring telescopic rods 202; the telescopic end of each spring telescopic rod 202 is fixedly connected to a fifth connecting plate 203; the two fifth connecting plates 203 located in the front are jointly fixedly connected to a heat sealer 204; the two fifth connecting plates 203 located in the rear are jointly fixedly connected to another heat sealer 204; each unloading barrel 14 is fixedly connected to eight spring limiting rods 205; a hook 206 is slidably connected to the limiting rod of each spring limiting rod 205; each hook 206 is fixedly connected to the spring on the corresponding spring limiting rod 205.

[0040] Each second limiting plate 8 is provided with eight through slots 8001 for cooperating with the hooks 206 to fix the packaging bag.

[0041] Each air suction port 14001 is provided with a breathable cloth to block the medicinal materials and prevent them from entering the air suction port 14001 during the air suction process.

[0042] Before filling the medicinal materials, the electric telescopic rod 12 drives the third connecting plate 13 and the discharge barrel 14 to move downward close to the second limiting plate 8, and the discharge barrel 14 drives the spring limiting rod 205 and the hook 206 to move downward close to the second limiting plate 8. At this time, the bag mouth of the packaging bag is flipped and covered on the second limiting plate 8. At this time, the bag mouth of the packaging bag only covers the upper half of the second limiting plate 8, and then all the hooks 206 move downward and under the limiting action of the second limiting plate 8 and the packaging bag thereon, all the hooks 206 slide on the limiting rods of the corresponding spring limiting rods 205, so that all the hooks 206 move in the direction away from the corresponding packaging bag, and compress the spring on the spring limiting rod 205, so that all the hooks 206 move to the bottom of the packaging bag, that is, at the spring limiting The spring on the positioning rod 205 pushes the corresponding hook 206, so that all the hooks 206 move toward the direction close to the packaging bag and enter the through groove 8001. At this time, the hook 206 is located directly below the bag mouth of the flipped packaging bag. After the medicinal materials are filled, the external air pump is controlled to extract the air in the packaging bag of the packaged medicinal materials through the suction port 14001, that is, the medicinal materials are vacuum-packed by suction. In the process of extracting the air in the medicinal material packaging bag, the packaging bag will shrink and squeeze the medicinal materials inside. Since the medicinal materials inside are solid block structures, that is, in this process, the parts of the packaging bag that do not meet the quality standards will be punctured by the medicinal materials, that is, the air in the limiting cylinder 7 and the second limiting plate 8 will enter the suction port 14001 through the rupture of the packaging bag and then be discharged. The third connecting plate 13 drives the discharge barrel 14 to move upward, and then the discharge barrel 14 drives the spring limiting rod 205 and the hook 206 to move upward, and hooks the edge of the packaging bag through the hook 206, and drives the packaging bag to move upward and away from the second limiting plate 8. In the process of vacuumizing the packaging bag, the inner wall of the packaging bag is in contact with the limiting frame 14002, that is, in this process, the packaging bag is driven to move upward by the discharge barrel 14, and then the heat sealer 204 loses the limit of the discharge barrel 14, that is, the spring telescopic rod 202 contracts and drives the four fifth connecting plates 203 to move, that is, the four The fifth connecting plate 203 drives the two heat sealers 204 to move toward each other, and the packaging bag is clamped by the two heat sealers 204. Then, the two heat sealers 204 are controlled to operate, that is, the packaging bag is sealed by heat sealing. Then, the electric telescopic rod 12 is controlled to further push the third connecting plate 13 to move upward, and the third connecting plate 13 drives the unloading barrel 14 to move upward. The unloading barrel 14 drives the hook 206 to continue to move upward, hook the edge of the packaging bag, and restore the turned-out packaging bag to its original state. Then, the electric telescopic rod 12 is controlled to contract and drive the unloading barrel 14 to move downward, push the heat sealer 204, and move the two heat sealers 204 away from each other, so that the packaging bag loses the limit of the heat sealer 204. Then, after the vacuum heat-sealed packaging is completed, the packaging bag falls back into the limit barrel 7.Then the first multi-stage electric push rod 6 is controlled to push the corresponding limit cylinder 7 downward to move close to the limit frame 2, and then the staff sorts out the packaging bags in the limit cylinder 7, selects the problematic packaging bags, and returns the medicinal materials to the external conveying equipment for subsequent medicinal material packaging.

[0043] Example 3

[0044] Based on the above embodiment 2, Figure 10-11 As shown, it also includes a transfer component, which includes a sixth connecting plate 301, a third limiting plate 302, a waste barrel 303, a filter screen 304 and a magnet block 305; five equidistantly distributed third limiting plates 302 are slidably connected to the limiting frame 2, and each third limiting plate 302 is provided with sixteen limiting holes 30201 in a rectangular array; all the third limiting plates 302 are fixedly connected to the sixth connecting plate 301; each limiting barrel 7 is slidably connected to a waste barrel 303; each waste barrel 303 is connected to a filter screen 304; each waste barrel 303 is fixedly connected to two symmetrically arranged magnet blocks 305.

[0045] The limiting frame 2 is provided with forty through holes 2001 in a rectangular array for discharging packaging bags filled with medicinal materials.

[0046] The waste barrel 303 and the filter screen 304 are configured as a quick-release structure for cleaning the medicinal material debris in the waste barrel 303 .

[0047] After the filling of medicinal materials is completed, the first multi-stage electric push rod 6 pushes the limiting cylinder 7 to move downward, and the limiting cylinder 7 simultaneously drives the waste barrel 303, the filter screen 304 and the magnet block 305 to move downward to contact the third limiting plate 302, and at the same time the magnet block 305 enters the limiting hole 30201, so that the magnet block 305 and the third limiting plate 302 are adsorbed together, and then the staff puts the collection frame on the limiting frame 2, so that the collection grid on the collection frame is aligned with the through hole 2001, and then the staff The staff takes out the packaging bag without medicinal materials in the limiting cylinder 7 from the opening of the second limiting plate 8, and then pulls the third limiting plate 302 through the handle on the sixth connecting plate 301, so that the third limiting plate 302 slides on the limiting frame 2, and at the same time, the third limiting plate 302 drives the waste cylinder 303, the filter screen 304 and the magnet block 305 to move with it and detach from the corresponding limiting cylinder 7, that is, the medicinal materials in the limiting cylinder 7 pass through the opening below, and then pass through the corresponding through hole 2001 into the collection container below. In the frame, it is necessary to know that during the packaging process of the packaging bag, vacuum heat sealing is adopted for packaging, that is, the medicinal materials in the packaging bag cannot move in the packaging bag, which leads to that some packaging bags containing medicinal materials cannot pass through the second limiting plate 8 and be taken out. If it is forcibly taken out, the packaging bag will rub against the second limiting plate 8, which leads to damage of the packaging bag and the medicinal materials. That is, through the above-mentioned method, the packaging bag is discharged through the waste barrel 303 below the limiting barrel 7 to seal the opening. At the same time, the staff observes whether there are any medicinal material debris remaining in the waste barrel 303. When it is found that there are medicinal materials in the waste barrel 303, the staff takes out the corresponding waste barrel 303, removes the filter 304 from the waste barrel 303, and then pours the medicinal materials into the external collection bucket. It is necessary to know that in the process of the above-mentioned state of medicinal materials, when the packaging bag is punctured by the medicinal materials, the medicinal materials therein will leak out, and the leaked medicinal materials need to be collected to avoid waste of medicinal materials, that is, the leaked medicinal materials are collected through the waste barrel 303.

[0048] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
