When the extrusion column moves in the opposite direction, the aluminum nail plate will leave the second sliding plate under the action of the extrusion plate, so that the sealing component will not be affected by the aluminum nail plate when it is restored, thereby reducing the time consumed in the process of compacting the explosive inside the medicine roll.

When the first hydraulic cylinder 2 is extended, the extrusion plate 32 will move downward with the extrusion column 3. At this time, the extrusion rod 732 will be inserted into the explosive inside from both ends of the packaging bag 6.

When the first hydraulic cylinder 2 contracts, the two extrusion columns 3 will separate from the two ends of the explosive. At this time, the sealing assembly 8 will seal the two ends of the packaging bag 6, so that the explosives in the packaged medicine roll are more compacted, thereby increasing the use effect of the medicine roll.

A first slide groove 411 is provided on one side of the first sliding plate 41, and a second slide groove 513 is provided on one side of the second sliding plate 51. The first slide groove 411 and the second slide groove 513 are located on the same side. A guide column 512 is fixedly connected to the top of the second sliding plate 51, and a feed groove 511 is provided on one side of the guide column 512. The feed groove 511 is directly above the feed groove 511. A mounting plate 33 is provided, and the shape of the feed slot 511 is the same as the aluminum nail at the bottom of the mounting plate 33.

When the sealing component 8 seals the packaging bag 6, the aluminum nail at the bottom of the aluminum nail plate can be pushed out to achieve sealing of the two ends of the packaging bag 6. When the extrusion column 3 moves in the opposite direction, the aluminum nail plate will leave the second sliding plate 51 under the action of the extrusion plate 32, so that the sealing component 8 will not be affected by the aluminum nail plate when it is restored, thereby reducing the time consumed in the process of compacting the explosive inside the medicine roll.

[0032] As an implementation method in this embodiment, Figures 7 to 10As shown, the sealing assembly 8 includes a dual-axis motor 81, and the output shafts at both ends of the dual-axis motor 81 are fixedly connected with synchronous gears 811, and the two sides of the synchronous gear 811 are respectively meshed and connected with a first tooth plate 82 and a second tooth plate 83, one side of the first tooth plate 82 is fixedly connected with a first sealing plate 84, and one side of the second tooth plate 83 is fixedly connected with a second sealing plate 85, the first sealing plate 84 is fixedly connected to one end of the first tooth plate 82 through a first connecting plate 841, and one side of the first sealing plate 84 is provided with an arc-shaped guide groove 842, and the second sealing plate 85 is fixedly connected to one end of the second tooth plate 83 through a second connecting plate 851, and one side of the second sealing plate 85 is directly opposite to the guide groove of the first sealing plate 84.

When the extrusion column 3 moves in the opposite direction, the end surface of the extrusion column 3 will leave the two ends of the explosive in the packaging bag 6. At this time, the double-axis motor 81 starts to rotate. When the double-axis motor 81 rotates, the synchronous gear 811 located on the output shaft on both sides thereof starts to rotate. When the synchronous gear 811 rotates, it will drive the first tooth plate 82 and the second tooth plate 83 to move toward each other, thereby driving the first The sealing plate 84 and the second sealing plate 85 are close to each other. When the second sealing plate 85 slides in the second sliding plate 51, it will be squeezed on one side of the bottom of the aluminum nail plate. As the synchronous gear 811 continues to rotate, the second sealing plate 85 will push the aluminum nail located at the bottom of the aluminum nail plate to leave the aluminum nail plate and slide in the second sliding plate 51 under the push of the second sealing plate 85. During the movement of the aluminum nail, the bottom of the packaging bag 6 will be confined in the middle of the aluminum nail. When the tip of the aluminum nail contacts the first sealing plate 84, the tip of the aluminum nail is located in the guide groove 842. Under the push of the second sealing plate 85, the aluminum nail will be deformed under the action of the guide groove 842 and buckled on the packaging bag 6, thereby achieving For sealing at both ends of the packaging bag 6, at this time, the aluminum nail plate has left the feed slot 511 of the second sliding plate 51 under the action of the extrusion plate 32, and then the dual-axis motor 81 starts to rotate in the opposite direction, so that the first tooth plate 82 and the second tooth plate 83 return to the initial position.

When the first clamping plate 4 and the second clamping plate 5 move, on the one hand, the first sliding plate 41 and the second sliding plate 51 will slide on the guide plate 12, and on the other hand, the first sealing plate 84 and the second sealing plate 85 will remain motionless. When the packaging bag 6 is completely exposed, the operator can collect the medicine roll.

[0033] In this embodiment, if Figures 7 to 10As shown, when the extrusion column 3 moves in the opposite direction, the first sealing plate 84 and the second sealing plate 85 will approach each other under the action of the dual-axis motor 81, and in the process of approaching, the aluminum nails on the aluminum nail plate will be removed, and the aluminum nails will be deformed by extruding them, thereby achieving sealing of the two ends of the packaging bag 6. In this way, not only can the two ends of the packaging bag 6 be synchronously sealed to avoid squeezing the explosives inside the packaging bag 6 during the sealing process, but also the air at both ends of the explosives in the packaging bag 6 can be eliminated, so that the explosives can always remain tight in the packaging bag 6.

[0034] The working principle of the technical solution provided by the present invention is as follows: When the operator makes the medicine roll, he first controls the first hydraulic cylinders 2 at the upper and lower ends of the packaging bag 6 to start, so that the squeezing columns 3 at the two ends can gradually enter and squeeze the two ends of the packaging bag 6, and squeeze the explosives in the packaging bag 6. When the squeezing columns 3 squeeze the explosives in the packaging bag 6, the auxiliary component 7 will be inserted into the explosives in the packaging bag 6 to squeeze the explosives deeper inside the packaging bag 6. During the squeezing, not only can the explosives in the middle part of the packaging bag 6 be made more compact, but also the air inside can be discharged when squeezing the explosives in the middle part of the packaging bag 6 to avoid air accumulation inside the explosives. With the gradual squeezing of the squeezing columns 3 at the upper and lower ends, the explosives in the packaging bag 6 can be made more compact. When the squeezing columns 3 reach the specified position, the first hydraulic cylinder 2 stops moving and starts to shrink. When the first hydraulic cylinder 2 starts to shrink and the squeezing columns 3 move in the opposite direction, the sealing component 8 starts to operate on the two ends of the packaging bag 6.

[0035] When the first hydraulic cylinder 2 is extended, the squeezing plate 32 will move downward with the squeezing column 3. At this time, the squeezing rod 732 will be inserted into the explosives inside the packaging bag 6 from both ends. When the squeezing plate 32 moves, it will drive the third support plate 721 to move downward, thereby extending the telescopic rod 71. During this process, the squeezing rod 732 will continuously squeeze the explosives in the middle part of the packaging bag 6, making the explosives in the middle part of the packaging bag 6 more compact. When the telescopic rod 71 is extended to the limit, the telescopic rod 71 stops extending, thereby stopping the second support plate 712 from moving. When the second support plate 712 stops moving, the third support plate 721 is still moving downward. At this time, the piston rod in the first oil storage rod 72 will be on the second support plate When the piston rod in the first oil storage rod 72 is extended, the oil in the second oil storage rod 73 will be sucked into the first oil storage rod 72 through the hose. At this time, the piston rod in the second oil storage rod 73 will move upward synchronously. During the upward movement of the piston rod in the second oil storage rod 73, the top of the fourth support plate 731 will be pushed up. When the fourth support plate 731 is lifted up, the squeezing rod 732 will move in the squeezing column 3. When the bottom of the squeezing rod 732 is flush with the bottom of the squeezing column 3, the first hydraulic cylinder 2 stops extending. At this time, the squeezing column 3 stops moving. The end surface of the squeezing column 3 is between the first sliding plate 41 and the second sliding plate 51 and is in the same horizontal position. At the same time, the middle part of the explosive inside the packaging bag 6 When the first hydraulic cylinder 2 contracts, the telescopic rod 71 begins to contract. When the telescopic rod 71 contracts to the initial position, the second support plate 712 stops moving. Then, the piston rod in the first oil storage rod 72 starts to move in the opposite direction under the action of the second support plate 712, and squeezes the excess oil in the first oil storage rod 72 into the second oil storage rod 73 through the hose, so that the piston rod assembly in the second oil storage rod 73 returns to the initial position. When the first hydraulic cylinder 2 contracts, the sealing assembly 8 starts to seal the two ends of the packaging bag 6. When squeezing the explosive in the packaging bag 6, the squeezing rod 732 is first inserted into the explosive, and the squeezing rods 732 at the upper and lower ends of the packaging bag 6 are The rod 732 will squeeze the explosive in the middle of the packaging bag 6, and at the same time, fill the hollow area in the middle of the explosive in the packaging bag 6, eliminate the air in the middle, and make the middle of the explosive more compact. At the same time, when the two squeezing columns 3 move toward each other, the squeezing column 3 will squeeze the two ends of the explosive in the packaging bag 6. When the squeezing column 3 is squeezing, the squeezing rod 732 will gradually be withdrawn from the explosive. In the process of the squeezing rod 732 being withdrawn, the gap between the bottom end of the squeezing rod 732 and the explosive will be refilled with the explosive pushed by the squeezing column 3. When the end face of the squeezing rod 732 is flush with the end face of the bottom of the squeezing column 3, not only the explosive in the middle of the packaging bag 6 is compacted by the upper and lower squeezing rods 732,The explosives at both ends of the packaging bag 6 will be compacted by the upper and lower squeezing columns 3, and the compacted explosives will be located between the two squeezing columns 3. When the first hydraulic cylinder 2 contracts, the two squeezing columns 3 will separate from the two ends of the explosives. At this time, the sealing component 8 will seal the two ends of the packaging bag 6, making the explosives in the packaged medicine roll more compact and increasing the use effect of the medicine roll.

[0036] When the extrusion column 3 squeezes the two ends of the packaging bag 6, the extrusion plate 32 will gradually approach the second sliding plate 51. When the extrusion plate 32 moves, the guide column 512 will pass through the second spring 332 and the fixed plate 331, and then the bottom of the second spring 332 will be squeezed on the surface of the second sliding plate 51. As the extrusion plate 32 continues to descend, the bottom of the aluminum nail plate located at the bottom of the mounting plate 33 will pass through the feed slot 511 above the second sliding plate 51 and enter the interior of the second sliding plate 51. Then the aluminum nail plate will stop moving under the action of the second sliding plate 51. When the aluminum nail plate stops moving, the mounting plate 33 will also stop moving. At this time, the extrusion plate 32 will squeeze the first spring 321, so that the extrusion column 3 can continue to move downward. When the extrusion column 3 moves in the opposite direction At this time, the sealing component 8 will push out the aluminum nail located at the bottom of the aluminum nail plate, so that the aluminum nail is buckled on the packaging bag 6, and complete the sealing of the packaging bag 6. As the extrusion column 3 continues to rise, the aluminum nail plate will leave the feed slot 511 of the second sliding plate 51. When the extrusion column 3 squeezes the explosive in the packaging bag 6, the extrusion plate 32 will bring the aluminum nail plate into the second sliding plate 51. When the sealing component 8 seals the packaging bag 6, the aluminum nail at the bottom of the aluminum nail plate can be pushed out to achieve the sealing of both ends of the packaging bag 6. When the extrusion column 3 moves in the opposite direction, the aluminum nail plate will leave the second sliding plate 51 under the action of the extrusion plate 32, so that the sealing component 8 will not be affected by the aluminum nail plate when it is restored, thereby reducing the time consumed in the process of compacting the explosive inside the medicine roll.

[0037] When the extrusion column 3 moves in the opposite direction, the end surface of the extrusion column 3 will leave the two ends of the explosive in the packaging bag 6, and the double-axis motor 81 starts to rotate. When the double-axis motor 81 rotates, the synchronous gear 811 located on the output shaft on both sides thereof starts to rotate. When the synchronous gear 811 rotates, it will drive the first tooth plate 82 and the second tooth plate 83 to move toward each other, thereby driving the first sealing plate 84 and the second sealing plate 85 to approach each other. When the second sealing plate 85 slides in the second sliding plate 51, it will be squeezed on one side of the bottom of the aluminum nail plate. As the synchronous gear 811 continues to rotate, The second sealing plate 85 will push the aluminum nail at the bottom of the aluminum nail plate to leave the aluminum nail plate and slide in the second sliding plate 51 under the push of the second sealing plate 85. During the movement of the aluminum nail, the bottom of the packaging bag 6 will be limited in the middle of the aluminum nail. When the tip of the aluminum nail contacts the first sealing plate 84, the tip of the aluminum nail is located in the guide groove 842. Under the push of the second sealing plate 85, the aluminum nail will be deformed under the action of the guide groove 842 and buckled on the packaging bag 6 to achieve sealing of both ends of the packaging bag 6. At this time, the aluminum nail plate has left the first sealing plate 84 under the action of the extrusion plate 32. The feeding slot 511 of the second sliding plate 51 is opened, and then the double-axis motor 81 starts to rotate in the opposite direction, so that the first tooth plate 82 and the second tooth plate 83 return to the initial position. When the operator needs to take out the medicine roll, the second hydraulic cylinder 11 on both sides is controlled to separate the first clamping plate 4 and the second clamping plate 5. When the first clamping plate 4 and the second clamping plate 5 move, on the one hand, the first sliding plate 41 and the second sliding plate 51 will slide on the guide plate 12, and on the other hand, the first sealing plate 84 and the second sealing plate 85 will remain motionless. When the packaging bag 6 is completely exposed, the operator can remove the medicine roll. The roll is collected, and when the extrusion column 3 moves in the opposite direction, the first sealing plate 84 and the second sealing plate 85 will approach each other under the action of the dual-axis motor 81, and in the process of approaching, the aluminum nails on the aluminum nail plate are removed, and the aluminum nails are deformed by squeezing the aluminum nails, thereby achieving sealing of the two ends of the packaging bag 6. In this way, not only can the synchronous sealing of the two ends of the packaging bag 6 be achieved, and the squeezing of the explosives inside the packaging bag 6 can be avoided during the sealing process, but also the air at both ends of the explosives in the packaging bag 6 can be eliminated, so that the explosives in the packaging bag 6 always remain in a tight state.
