Description

Technical Field

[0001] The present invention relates to the technical field of pharmaceutical production, and specifically to an aluminum-plastic blister packaging machine. Background Art

[0002] Aluminum-plastic blister packaging is mainly composed of an upper aluminum foil and a lower PVC blister, and is mainly used for packaging pharmaceuticals, specifically for packaging capsule-shaped pharmaceuticals. It can ensure that each pharmaceutical is isolated from each other, and also has a good effect of isolating moisture, air and light, which can ensure the efficacy of the pharmaceutical and extend the shelf life of the pharmaceutical.

[0003] In the patent document with the application number 201621301892.X, an aluminum-plastic blister packaging machine is disclosed. Specifically, a blister film roller, a forming device, a medicine adding device, an aluminum foil roller, a heating device and a shearing device are sequentially arranged on a base, so that through the cooperative action of the above devices in sequence, the operations of adding, encapsulating and shearing the pharmaceuticals are realized.

[0004] In the above technical solution, two heating plates are used to heat-seal the aluminum foil, PVC blister and capsule. During heat-sealing, since the medicine placing groove is made of a downwardly convex plastic material, the lower heating plate will be close to the medicine placing groove. If a grid-shaped heating plate is used to encapsulate multiple medicine placing grooves simultaneously, the medicine placing grooves will be affected by the heating plate, resulting in easy deformation of the plastic. At the same time, if there is a deviation in the positions of the aluminum foil and the medicine placing groove, the medicine placing groove will be directly affected by the heating plate, leading to melting of the medicine placing groove and affecting the sealing efficiency of the capsule; and when there is a deviation in the positions of the medicine placing groove and the aluminum foil, the tightness of the aluminum foil will be affected. During pressing, the longer aluminum foil will accumulate on the medicine placing groove in multiple layers, resulting in poor sealing effect on the medicine placing groove. Summary of the Invention

[0006] The technical problem solved by the present invention is: to solve the problem in the prior art that during heat-sealing, since the medicine placing groove is made of a downwardly convex plastic material, the lower heating plate will be close to the medicine placing groove. If a grid-shaped heating plate is used to encapsulate multiple medicine placing grooves simultaneously, the medicine placing grooves will be affected by the heating plate, resulting in easy deformation of the plastic.

[0007] The present invention can be realized by the following technical solutions: an aluminum-plastic blister packaging machine, including a pressing component, the pressing component includes a first pressing support plate and a second pressing support plate, a pressing mechanism is arranged at the bottom of the first pressing support plate, a pressing groove is formed on the second pressing support plate, a pressing mesh plate is fixed on the pressing groove, and the pressing mesh plate cooperates with the pressing mechanism.

[0008] A further technical improvement of the present invention lies in that: the second pressing support plate is fixed to the output end of the first pressing telescopic rod, the first pressing telescopic rod is fixed to the third pressing support plate, and a positioning component is arranged on the second pressing support plate.

[0009] A further technical improvement of the present invention lies in that: the third pressing support plate is fixed to the adjusting screw rod, the adjusting screw rod is slidably connected to the adjusting base, and two groups of fixing bolts are threadedly arranged on the adjusting screw rod, and the fixing bolts are located on both sides of the adjusting base.

[0010] A further technical improvement of the present invention lies in that: the positioning component includes a positioning sensor, the positioning sensor is fixed to the end of the end connecting rod, a first sliding groove and an extrusion groove are formed on the second pressing support plate, the first sliding groove and the extrusion groove are communicated, and the end connecting rod is respectively slidably connected to the first sliding groove and the extrusion groove.

[0011] A further technical improvement of the present invention lies in that: a second sliding rack is fixed to the end of the end connecting rod, a first sliding rack is fixed to the second pressing support plate, an intermediate rotating gear is rotatably arranged on the third pressing support plate, the intermediate rotating gear is respectively meshed with the second sliding rack and the first sliding rack, a second sliding plate is fixed to the end of the second sliding rack, and a second sliding groove is formed on the third pressing support plate, and the second sliding plate is slidably connected to the second sliding groove.

[0012] A further technical improvement of the present invention lies in that: a first limiting plate is fixed to the side of the first pressing support plate, and a first limiting groove is formed on the second pressing support plate, and the first limiting groove cooperates with the first limiting plate.

[0013] A further technical improvement of the present invention lies in that: a turning component is arranged on the side of the pressing component through a cutting device. The turning component includes a moving conveyor belt and a turning conveyor belt. The end of the moving conveyor belt is inclined, and the moving conveyor belt is located beside the rotating roller, and turning protrusions are arranged on the rotating roller.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this application, first, the aluminum foil and the PVC board are placed on the pressing assembly, so that the aluminum foil and the PVC board are transported to the second pressing support plate until the position sensors detect the positions of the aluminum foil and the PVC board. Subsequently, the first pressing telescopic rod moves upward, driving the second pressing support plate to move upward and the first pressing support plate to move downward, enabling the pressing mechanism and the pressing mesh plate to cooperate. At this time, the medicine placing groove is located inside the pressing groove, and the part to be pressed is on the pressing mesh plate. The pressing mechanism is used to press it, so that when the aluminum foil and the PVC board are pressed, the medicine placing groove is prevented from contacting the heat source, protecting the medicine placing groove from being melted by high temperature, and thus avoiding the deformation of the medicine placing groove.

[0016] 2. In this application, since the first pressing telescopic rod moves upward, driving the first sliding rack to move upward, under the meshing action of the middle rotating gear with the first sliding rack and the second sliding rack, the end connecting rod moves downward.

When the aluminum foil and the PVC board are pressed, the position sensor is protected to prevent the internal circuit from being affected by the high temperature.

[0017] 3. After the pressing of the aluminum foil and the PVC board is completed in this application, the first pressing support plate and the second pressing support plate move away from each other. At this time, the pressed medicine package is placed inside the cutting device. Then, the cutting device is used to cut the medicine package. After cutting, the power motor drives the cam to rotate, so that under the cooperation of the base, the first rotating seat is driven to rotate. Under the action of the rotating rod, the second slider moves on the second rotating seat, driving the whole cutting device to move, and moving the cutting device to the flipping assembly. The flipping assembly is used to flip the medicine package, so that after the medicine is initially flipped, the outside of the medicine placing groove of the medicine package is further wrapped to further ensure the sealing degree of the medicine and extend the effective period of the medicine.

[0027] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in combination with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features, and their effects of the present invention as follows.

[0028] Please refer to Figure 1-7As shown, an aluminum-plastic blister packaging machine includes a lamination assembly 3. A cutting device 2 is arranged at the output end of the lamination assembly 3 through an adjustment assembly 4, and a flipping assembly 1 is arranged on the side of the cutting device 2. Specifically, first, the aluminum foil and the PVC blister film are laminated by the lamination assembly 3. Subsequently, the laminated medicine is cut by the cutting device 2. The cut medicine is driven by the adjustment assembly 4 to drive the cutting device 2 to reach the flipping assembly 1 for flipping. The back of the flipped medicine is further laminated and sealed by the aluminum foil, realizing the protection of the medicine placement groove, and avoiding the invisible fine cracks caused by high-temperature lamination during the processing of the medicine placement groove, which may affect the final medicinal properties of the medicine and the storage period of the medicine.

[0029] Specifically, in this application, first, the lamination assembly 3 includes a first lamination support plate 313, a second lamination support plate 310, a third lamination support plate 34, and an adjustment base 35. The adjustment base 35 is fixed at a fixed position for realizing the overall support of the lamination assembly 3. An adjustment screw 37 is slidably arranged on the lamination assembly 3. Two sets of fixing bolts 36 are arranged on the adjustment screw 37, and the fixing bolts 36 are respectively located on both sides of the adjustment base 35. By adjusting the positions of the fixing bolts 36 on the adjustment screw 37, the position of the third lamination support plate 34 at the end of the adjustment screw 37 is adjusted. A first lamination telescopic rod 38 is fixed on the third lamination support plate 34, and the end of the first lamination telescopic rod 38 is fixed with a second lamination support plate 310. A first lamination support plate 313 is arranged above the second lamination support plate 310 in a matching manner, and the first lamination support plate 313 is driven by a hydraulic cylinder.

[0030] During this process, the hydraulic cylinder is used to drive the first lamination support plate 313 to move longitudinally. Subsequently, the first lamination telescopic rod 38 is extended, so that the second lamination support plate 310 and the first lamination support plate 313 cooperate to laminate the aluminum foil and the PVC board located between the first lamination support plate 313 and the second lamination support plate 310, and seal the medicine. At the same time, in this application, since the PVC board is always in a horizontal state when pressure is applied up and down, the aluminum foil and the PVC board will not be deformed due to the downward pressure, ensuring that the tension degree of the aluminum foil remains consistent, and avoiding the change in the tension degree of the aluminum foil after lamination, which may cause the aluminum foil to be stacked and pressed on the next PVC board, affecting the sealing degree of the medicine.

[0031] Therefore, a pressing mechanism 31 is fixed on the first pressing support plate 313. The pressing mechanism 31 adopts a hot pressing method, and the output end of the pressing mechanism 31 is in a grid shape, which is used to cooperate with the multi-grid arrangement during medicine pressing. A pressing groove 33 is formed on the second pressing support plate 310, and a pressing mesh plate 32 is fixed on the pressing groove 33. The mesh size of the pressing mesh plate 32 cooperates with the pressing mechanism 31. That is, when pressing down, the medicine placing groove passes through the pressing mesh plate 32 and reaches the inside of the pressing groove 33. Subsequently, when the pressing mechanism 31 presses down, the medicine placing groove is inside the pressing groove 33, and the part to be pressed is placed on the pressing mesh plate 32. When the pressing mechanism 31 presses, it is avoided that the heating plate contacts the medicine placing groove, so as to avoid the occurrence of damage caused by the medicine placing groove contacting the heat source.

[0032] In order to realize the cooperative limit of the first pressing support plate 313 and the second pressing support plate 310, a first limiting plate 312 is fixed on the first pressing support plate 313, and a first limiting groove 311 is formed on the second pressing support plate 310. The first limiting plate 312 and the first limiting groove 311 are used in cooperation to realize the position cooperation of the first pressing support plate 313 and the second pressing support plate 310.

[0033] Before pressing the aluminum foil and the PVC board, if the position of the medicine placing groove deviates from the position of the pressing mesh plate 32, it will cause the medicine placing groove not to enter the inside of the pressing groove 33, and the medicine placing groove will be pressed by the pressing mechanism 31, resulting in pressing failure and the appearance of defective products. To solve the above technical problems, a positioning component 39 is also included.

[0034] Specifically, the positioning component 39 includes a positioning sensor 3910, which is fixedly installed at the end of the end connecting rod 399. A first sliding groove 398 is formed on the second pressing support plate 310, and the end connecting rod 399 is slidably connected to the first sliding groove 398, so as to realize the accommodation of the positioning sensor 3910 inside the first sliding groove 398. Specifically, the positioning sensor 3910 adopts an infrared sensor or a distance sensor, which is used to sense the positions of the aluminum foil and the PVC board. When the positions of the aluminum foil and the PVC board are sensed, the positioning sensor 3910 is accommodated inside the first sliding groove 398, and then the aluminum foil and the PVC board are pressed by a pressing device.

[0035] Specifically, an extrusion groove 396 is formed at the bottom of the first sliding groove 398. An extrusion spring 397 is arranged inside the extrusion groove 396, and the other end of the extrusion spring 397 is fixed to the end connecting rod 399. When the end connecting rod 399 slides, the extrusion spring 397 will be extruded. The position of the positioning sensor 3910 is ensured by using the extrusion spring 397, so as to avoid the sensing failure caused by the free fall of the positioning sensor 3910 to the lowest position when the power fails below.

[0036] A second sliding rack 395 is fixed to the end of the end connecting rod 399. A first sliding rack 391 is fixed to the second pressing support plate 310. An intermediate rotating gear 392 is fixed to the third pressing support plate 34. The intermediate rotating gear 392 is meshed and connected with the first sliding rack 391 and the second sliding rack 395 respectively. A second sliding plate 394 is fixed to the bottom of the second sliding rack 395. A second sliding groove 393 is formed in the third pressing support plate 34, and the second sliding groove 393 is slidably connected with the second sliding plate 394.

[0037] During use, when the first pressing telescopic rod 38 extends and drives the second pressing support plate 310 to move upward, the first sliding rack 391 will move upward, causing the intermediate rotating gear 392 to rotate, thereby driving the second sliding rack 395 to move downward and driving the positioning sensor 3910 to move longitudinally. At this time, since the second pressing support plate 310 moves downward and the positioning sensor 3910 also moves downward, the positioning sensor 3910 is received, and the first sliding groove 398 performs the receiving operation on the positioning sensor 3910.

[0038] Furthermore, the adjustment assembly 4 includes a second slider 44, which is fixed to the bottom end of the cutting device 2 and is used to drive the cutting device 2 to move when the second slider 44 moves. The second slider 44 is slidably arranged on the second rotating seat 45, and the second rotating seat 45 is fixedly installed at a fixed position. The first rotating seat 41 is rotatably connected to the fixed position through a torsion spring. A rotating rod 46 is rotatably arranged at the bottom of the second slider 44. An intermediate sliding rod 43 is fixed in the middle of the first rotating seat 41. A first slider 42 is slidably arranged on the intermediate sliding rod 43. The side of the first slider 42 is rotatably connected to the other end of the rotating rod 46. A matching base 48 is fixed to the side of the first rotating seat 41. A cam 47 is rotatably arranged at the fixed position, and the cam 47 is connected with the matching base 48 in a matching manner.

[0039] Specifically, when the power motor drives the cam 47 to rotate, the cam 47 is used to squeeze the matching base 48, so that the first rotating seat 41 rotates, driving the position of the rotating rod 46 to move. A return spring is fixed on the middle sliding rod 43, and the other end of the return spring is fixed on the first slider 42. When the first slider 42 moves to a certain position on the middle sliding rod 43, the second slider 44 slides on the second rotating seat 45. Thus, the movement of the second slider 44 drives the movement of the cutting device 2, and the cut medicine packages are transported to the flipping assembly 1, realizing the flipping of the medicine packages, which is convenient for subsequent film covering on the back of the medicine packages. Due to the action of the cam 47, reciprocating motion can be achieved, and the medicine packages are reciprocally cut, transported, and placed.

[0040] To realize the flipping of the medicine packages, the flipping assembly 1 includes a conveying assembly, a positioning guide plate 14, and a rotating roller 17. After the cutting device 2 places the medicine packages on the conveying assembly, the positioning guide plate 14 is used to fix and guide the positions of the medicine packages, and then the medicine packages are conveyed to the rotating roller 17 through the conveying assembly, and the rotating roller 17 realizes the automatic flipping of the medicine packages.

[0041] Specifically, the conveying assembly includes a flipping conveyor belt 18 and a moving conveyor belt 11. The flipping conveyor belt 18 is located above the moving conveyor belt 11. After flipping the medicine packages on the moving conveyor belt 11, the medicine packages are conveyed through the flipping conveyor belt 18 and then conveyed to the film covering mechanism to protect the back of the medicine packages with film. Specifically, a pressure roller 12 is provided on the moving conveyor belt 11 to change the angle of the moving conveyor belt 11, so that the moving conveyor belt 11 is first flat, and then, through the action of the pressure roller 12, the moving conveyor belt 11 is inclined upward to realize the conveyance of the medicine packages. A connecting rotating rod 13 is fixed on the side of the moving conveyor belt 11, and a rotating connecting belt 15 is fixed on the connecting rotating rod 13. The medicine packages are placed on the rotating connecting belt 15 for conveying movement until the medicine packages reach the position of the rotating roller 17 for flipping operation.

[0042] A positioning and guiding plate 14 is provided in the middle of the rotating connecting belt 15. The positioning and guiding plate 14 includes a first guiding substrate 141. Second guiding substrates 142 and third guiding substrates 143 are symmetrically fixed to the sides of the first guiding substrate 141. The second guiding substrate 142 and the third guiding substrate 143 are inclined upward. Between adjacent medicine placing grooves of the medicine packaging, it first passes through the first guiding substrate 141 for preliminary positioning, and then the placing groove is further positioned under the action of the second guiding substrate 142 and the third guiding substrate 143. The ends of the second guiding substrate 142 and the third guiding substrate 143 are located on both sides of the adjacent placing grooves, realizing the limiting of the placing grooves, and further realizing the limiting of the medicine packaging. At the same time, due to the second guiding substrate 142 and the third guiding substrate 143 being inclined upward, the medicine is inclined upward until the placing groove of the medicine reaches the position of the flipping protrusion 16 on the rotating roller 17. The flipping protrusion 16 contacts the placing groove, and then the power motor drives the rotating roller 17 to rotate, so that the flipping protrusion 16 drives the placing groove to move upward. A guiding arc plate 19 is provided at the fixed position, that is, when the medicine packaging contacts the guiding arc plate 19, the medicine packaging is flipped onto the flipping conveyor belt 18, and the medicine packaging is conveyed by the conveying of the flipping conveyor belt 18 to realize the flipping of the medicine packaging.

[0043] When the present invention is in use, first place the aluminum foil and the PVC board on the pressing component 3, so that the aluminum foil and the PVC board are transported to the second pressing support plate 310 until the positioning sensor 3910 detects the positions of the aluminum foil and the PVC board. Then, the first pressing telescopic rod 38 moves upward, driving the second pressing support plate 310 to move upward, and moving the first pressing support plate 313 downward, so that the pressing mechanism 31 and the pressing mesh plate 32 cooperate. At this time, the placing groove is located inside the pressing groove 33, and the part to be pressed is located on the pressing mesh plate 32. The pressing mechanism 31 presses it, so that when pressing the aluminum foil and the PVC board, the placing groove is prevented from contacting the heat source, protecting the placing groove from being deformed due to high-temperature melting;

[0044] At this time, since the first pressing telescopic rod 38 moves upward, driving the first sliding rack 391 to move upward, under the meshing action of the middle rotating gear 392, the first sliding rack 391 and the second sliding rack 395, the end connecting rod 399 moves downward. At this time, due to the upward movement of the second pressing support plate 310 and the downward movement of the end connecting rod 399, the positioning sensor 3910 is driven to move downward, so that the positioning sensor 3910 enters the inside of the first sliding groove 398, realizing the storage of the positioning sensor 3910;

[0045] After the lamination of the aluminum foil and the PVC board is completed, the first lamination support plate 313 and the second lamination support plate 310 move away from each other. At this time, the laminated drug package is placed inside the cutting device 2. Then, the cutting device 2 is used to cut the drug package. After cutting, the power motor drives the cam 47 to rotate. Under the action of the matching base 48, the first rotating seat 41 is driven to rotate. Under the action of the rotating rod 46, the second slider 44 moves on the second rotating seat 45, driving the whole cutting device 2 to move. The cutting device 2 is moved to the flipping assembly 1, and the flipping assembly 1 is used to flip the drug package.

[0046] The drug package is flipped onto the rotating connecting belt 15, and the rotating connecting belt 15 is used to convey the drug package until the drug package is guided by the first guiding substrate 141, that is, guided through the gap of the medicine placing groove by the first guiding substrate 141. Subsequently, the second guiding substrate 142 and the third guiding substrate 143 guide the gap of the medicine placing groove, so as to realize the position limiting effect on the drug package. Then, the end of the drug package reaches the position of the rotating roller 17. Under the driving of the power motor, the rotating roller 17 rotates, and the flipping protrusion 16 contacts the lateral gap of the medicine placing groove. During the rotation of the rotating roller 17, the drug package is gradually flipped until the drug package contacts the guiding arc plate 19 and is further flipped. The end of the drug package falls on the flipping conveyor belt 18, so that the flipped drug package is driven by the flipping conveyor belt 18 to be film-coated on the back.

[0047] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Although the present invention has been disclosed as above with a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to form an equivalent embodiment with equivalent changes within the scope of the technical solution of the present invention. However, as long as it does not depart from the content of the technical solution of the present invention, any simple modification, equivalent change and modification made to the above embodiment according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
