[0058] In order to make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the embodiments and drawings. Herein, the illustrative embodiments of the present application and the description thereof are used to explain the present application, but are not used as a limitation of the present application.

[0060] It should be emphasized that the term "comprises / comprising" as used herein means the presence of stated features, elements, steps or components, but does not preclude the presence or addition of one or more other features, elements, steps or components.

[0061] Herein, it is also necessary to mention that, if not specially mentioned, the term "connection" as used herein can not only mean direct connection, but also means indirect connection with the presence of intermediate objects.

[0062] In the following, the embodiments of the present application will be described with reference to the drawings. In the drawings, the same reference numerals represent the same or similar parts, or the same or similar steps.

[0063] Reference Figure 1 and Figure 2The utility model embodiment provides a kind of stripping device for aluminium plastic sheet tablet, including rack and first conveying roller way mechanism, second conveying roller way mechanism, slit mechanism and pressure mechanism being installed on rack;Wherein, first conveying roller way mechanism is arranged in the upper of second conveying roller way mechanism, the starting end of second conveying roller way mechanism is arranged in the just below of the end of first conveying roller way mechanism, to make the aluminium plastic sheet medicine board by the end of first conveying roller way mechanism drop after rotating 180 degrees and drop on second conveying roller way mechanism;Slit mechanism is arranged in the upper of first conveying roller way mechanism, slit mechanism can be broken to the aluminium film of the aluminium plastic sheet medicine board passing below it;Pressure mechanism is arranged in the upper of second conveying roller way mechanism, pressure mechanism can pressurize to the bubble cap of the aluminium plastic sheet medicine board passing below it, to make tablet drop by broken aluminium film.

[0064] In the above embodiment, the stripping device achieves automatic and continuous stripping of aluminium plastic sheet tablets through the ingenious design of the first and second conveying roller way mechanisms. After the tablets drop from the end of the first conveying roller way mechanism, they can rotate 180 degrees and accurately fall on the second conveying roller way mechanism. This process reduces the steps of manual operation and improves the stripping efficiency. The slit mechanism ensures the accurate position of the broken aluminium film, laying a foundation for the smooth dropping of subsequent tablets. The pressure mechanism can make the tablets drop smoothly through the previously broken aluminium film by pressing the bubble cap of the aluminium plastic sheet tablet passing below it. This improves the efficiency of tablet stripping and ensures the integrity and quality of the tablets. The entire stripping device has a reasonable structure design, and the components cooperate closely, which can achieve automatic stripping of aluminium plastic sheet tablets. This not only reduces the intervention of manual operation and reduces labor intensity, but also improves the automation level of the production line.

[0065] In some embodiments, the stripping device for aluminium plastic sheet tablets further includes a spacing adjustment mechanism, which is arranged on the rack. The spacing adjustment mechanism is connected to the slit mechanism and the pressure mechanism, and is used to adjust the spacing inside the slit mechanism and the pressure mechanism to adapt to aluminium plastic sheet tablets of different specifications. The spacing adjustment mechanism can flexibly adjust the spacing inside the slit mechanism and the pressure mechanism according to aluminium plastic sheet tablets of different specifications. This means that the stripping device can handle aluminium plastic sheet tablets of multiple sizes without the need to replace or adjust the entire device, greatly enhancing its versatility and flexibility.

[0066] In some embodiments, the pitch adjusting mechanism comprises a hand wheel 20, a bidirectional screw 21, two screw nuts 22, two movable baffles 23 and a plurality of guide rails 13; wherein the hand wheel 20 is fixedly connected with one end of the bidirectional screw 21; the two ends of the bidirectional screw 21 are rotatably connected with the rack respectively; the two screw nuts 22 are arranged at the two ends of the bidirectional screw 21 respectively, and when the bidirectional screw 21 rotates, the two screw nuts 22 can move towards or away from each other; the two screw nuts 22 are fixedly connected with the two movable baffles 23 respectively; the movable baffles 23 are transversely slidably connected with the rack; the top of the two movable baffles 23 are fixedly connected with the slitting mechanism respectively; the bottom of the two movable baffles 23 are fixedly connected with the pressing mechanism respectively; the guide rails 13 are fixedly arranged on the upper and lower sides of the two movable baffles 23 moving towards each other, for supporting the edge of the aluminum-plastic plate.

[0067] In the above embodiments, referring to Figure 6 , Figure 7 and Figure 8 , the bidirectional screw 21 is driven to rotate by the hand wheel 20, so that the moving distance of the two screw nuts 22 on the bidirectional screw 21 can be accurately controlled, thereby moving the two movable baffles 23 towards or away from each other, so as to adapt to aluminum-plastic plate of different specifications, and ensure the accuracy and stability of the stripping process. The guide rails 13 enable the aluminum-plastic plate to move in the L-shaped groove inside the guide rails 13 without deviation, thereby providing guarantee for the accurate operation of the slitting mechanism and the pressing mechanism. The movable baffles 23 have a cross section of approximately T-shaped structure, one side of which is designed as a thick rectangular cross section facing the brush roller, and the other side is designed as a thin L-shaped cross section and a sawtooth shape facing the rubber roller, so that the strength and rigidity of the entire baffle are guaranteed. In particular, the guide rails 13 below the pressing mechanism increase in thickness outwardly, thereby improving the reliability of the local structure under impact load working conditions. The movable baffles 23 extend to the feeding hopper 26. The two movable side plates of the feeding port are directly installed on the movable baffles and move with the movable baffles. The operator adjusts the movable baffles according to the actual width size of the plate.

[0068] In some embodiments, referring to Figure 3The slitting mechanism includes a plurality of blades 1 or scribers arranged side by side and a first guide shaft 2, a first pressing plate 3, a second pressing plate 4, and a plurality of first springs 5. The plurality of blades 1 or scribers are arranged in a direction perpendicular to the conveying direction of the first conveying roller mechanism. The first pressing plate 3 is fixedly connected to the guide rail 13 on one movable baffle 23, and the second pressing plate 4 is fixedly connected to the guide rail 13 on the other movable baffle 23. One end of the first guide shaft 2 is fixedly connected to the second pressing plate 4, and the axis direction of the first guide shaft 2 is the same as the arrangement direction of the plurality of blades 1 or scribers. Each blade 1 or scriber is arranged on the first guide shaft 2 and can slide along the first guide shaft 2. The first pressing plate 3 and the second pressing plate 4 are respectively located on both sides of the first guide shaft 2, and the first pressing plate 3 can slide along the first guide shaft 2. The first pressing plate 3 and the second pressing plate 4 are respectively in contact with the blades 1 or scribers on both sides. The first spring 5 is arranged between two adjacent blades 1 or scribers, so that the distance between the blades 1 or scribers can be adjusted by changing the distance between the first pressing plate 3 and the second pressing plate 4.

[0069] It should be noted that the first pressing plate 3 and the second pressing plate 4 are provided with bolts, and the first pressing plate 3 and the second pressing plate 4 are installed on the stepped surface at the top of the guide rail 13 through the bolts. The bolts can adjust the height of the slitting mechanism as a whole.

[0070] In the above embodiment, the distance between the first pressing plate 3 and the second pressing plate 4 can be changed to accurately adjust the distance between the blades 1 or scribers. This design makes the slitting mechanism suitable for aluminum-plastic plate sheets of different widths, ensuring the accuracy and stability of the aluminum film cutting. Since the slitting mechanism can accurately adjust the distance between the blades 1 or scribers and has high durability and stability, it has strong adaptability and can handle aluminum-plastic plate sheets of various specifications and sizes.

[0071] In some embodiments, the medicine pressing mechanism includes a pressing sub-mechanism, a medicine pressing sub-mechanism, and a rebound mechanism; the pressing sub-mechanism can be attached to the medicine pressing sub-mechanism, used to drive the medicine pressing sub-mechanism to press down to press the medicine tablets in the blister out, and the rebound mechanism is used to drive the medicine pressing sub-mechanism to reset; the medicine pressing sub-mechanism includes a plurality of pressing rod groups arranged side by side, at least two second guide shafts 15, a plurality of sliding sleeves 16, a plurality of third springs 17, two pressure rollers 18 and two pressure roller supports 19; wherein the sliding sleeve 16 is fixedly arranged on the outer side wall of the pressing rod group, the axis of the second guide shaft 15 is the same as the arrangement direction of the pressing rod group, and the sliding sleeve 16 is in sliding connection with the second guide shaft 15; the third spring 17 is arranged between adjacent sliding sleeves 16; two pressure rollers 18 are arranged on both sides of the plurality of pressing rod groups, the axis of the pressure roller 18 is parallel to the extension direction of the single pressing rod group, and the edge of the pressure roller 18 is attached to the outermost pressing rod group; the pressure roller support 19 is fixedly connected with the movable baffle 23, and the pressure roller support 19 is rotatably connected with both ends of the pressure roller 18, so that the distance between the two pressure roller supports 19 can be changed to adjust the spacing of each pressing rod group.

[0072] In the above embodiments, by changing the distance between the two pressure roller supports 19, the spacing between each pressing rod group can be accurately adjusted. This design makes the medicine pressing mechanism suitable for aluminum plastic plate medicine plate blister of different sizes, ensures that the medicine tablets can be uniformly stressed when pressing, and avoids damage or incomplete pressing of the medicine tablets. The design of the rebound mechanism ensures that the medicine pressing sub-mechanism can quickly reset after completing the medicine pressing action, preparing for the next medicine pressing action. The edge of the pressure roller 18 is attached to the outermost pressing rod group, which can ensure that the medicine tablets can be evenly distributed when subjected to pressure, avoiding damage or incomplete pressing of the medicine tablets due to uneven pressure.

[0073] In some embodiments, referring to Figure 4 and Figure 5 , the bottom of the pressing rod group on both sides is arranged beyond the bottom of the pressing rod group in the middle and corresponds to the position of the guide rail 13, the pressing rod group includes a plurality of pressing rods 6 arranged side by side, and the bottom of the pressing rod 6 has an elastically expandable pressing head end. The bottom of the pressing rod group on both sides is arranged beyond the bottom of the pressing rod group in the middle, which makes the pressing rod groups on both sides first contact the edge part of the aluminum plastic plate medicine plate when pressing the medicine tablets, thereby exerting more pressure on the edge medicine tablets. This helps to ensure that the edge medicine tablets can also be effectively pressed out, avoiding the problem of incomplete peeling due to insufficient force on the edge medicine tablets. The design of the pressing rod group bottom corresponding to the position of the guide rail 13 not only provides stable support for the pressing rod group, but also enhances the structural stability of the entire medicine pressing mechanism. This design makes the medicine pressing mechanism stable and less likely to shake when pressing the medicine tablets, thereby improving the accuracy and reliability of the medicine pressing.

[0074] It should be noted that the bottom of the pressing rod 6 can be circularly configured with a diameter of about 3mm or rectangularly configured with a size of 3x3mm. Referring to Figure 5 , ten pressing rods 6 are vertically arranged to form a pressing rod group, and nine pressing rod groups form a pressing rod matrix. The width between the pressing rod groups is adjusted by the third spring 17. The outer part of all the pressing rod groups can be covered by iron sheets to form an overall structure. The bottom of the outermost pressing rod group corresponds to the position of the L-shaped inner groove of the guide rail 13, which is used to press the edge of the medicine plate on the guide rail 13. When the nine pressing rod groups are completely pressed (with a spacing of 0), the size of the pressing rod matrix is 40x36; when the nine pressing rod groups are pulled apart with a spacing of 5mm, the size of the pressing rod matrix is 40x76. This width size is close to the width size (35-75) of common aluminum plastic medicine plates. Therefore, the device is suitable for common aluminum plastic medicine plate stripping operations.

[0075] In some embodiments, the pressing sub-mechanism includes a motor 7, a crankshaft 8, a connecting rod 9, and a pressing plate 10. The motor 7 is fixedly arranged on the frame, the two ends of the crankshaft 8 are rotatably connected to the frame, and the motor 7 is connected to one end of the crankshaft 8 through a belt and a belt pulley. One end of the connecting rod 9 is rotatably connected to the curved part of the crankshaft 8, and the other end of the connecting rod 9 is rotatably connected to the top of the pressing plate 10. The pressing plate 10 is vertically slidably connected to the frame, and the bottom of the pressing plate 10 is used to press the top of the pressing rod group.

[0076] In the above embodiment, the motor 7 is connected to the crankshaft 8 through a belt and a belt pulley. This transmission mode is stable and reliable, and can ensure that the power output by the motor is smoothly transmitted to the crankshaft 8. The rotation of the crankshaft 8 further drives the pressing plate 10 to move up and down reciprocally through the connecting rod 9, thereby realizing stable pressing of the medicine pressing sub-mechanism.

[0077] In some embodiments, the rebound mechanism includes a spring seat 11 and a second spring 14. The spring seat 11 is fixedly connected to the outermost pressing rod 6. The two ends of the second spring 14 are fixedly connected to the spring seat 11 and the guide rail 13, respectively, and the second spring 14 has a spring force. The rebound mechanism ensures that the medicine pressing sub-mechanism can quickly and stably rebound to the initial position after completing the medicine pressing action through the spring force of the second spring 14. When the second spring 14 is at the natural length, a spacing of about 2mm is left between the outermost pressing rod group and the guide rail 13, so that the edge of the medicine plate can pass through the bottom of the pressing rod group.

[0078] In some embodiments, the first and second conveying roller mechanisms comprise a rubber roller 24, a brush roller 25 and a driving mechanism; the driving mechanism is used to drive the rotation of the rubber roller 24 and the brush roller 25; in the first conveying roller mechanism, the rubber roller 24 is located above the brush roller 25; in the second conveying roller mechanism, the rubber roller 24 is located below the brush roller 25. The combination of the rubber roller 24 and the brush roller 25 provides better support and guidance for the blister tablets during the conveying process. The rubber roller 24 provides the main conveying power, while the brush roller 25 helps the tablets maintain a stable conveying state by the slight friction between its bristles and the tablet surface, avoiding conveying problems caused by shaking or deviation.

[0079] In some embodiments, the peeling device for blister tablets further comprises a feeding hopper 26, a medicine bucket 27 and a waste bucket 28; the feeding hopper 26 is arranged above the starting end of the first conveying roller mechanism; the medicine bucket 27 is arranged below the medicine pressing mechanism and the second conveying roller mechanism; the waste bucket 28 is arranged below the end of the second conveying roller mechanism.

[0080] The working principle of the above embodiments is as follows. The tablets in the blister film are peeled out by the downward pressing method, provided that the surrounding film of the tablets has sufficient support force, otherwise, the film will be deformed under the pressure of the pressing plate (or roller), causing the tablets to be pressed out. The common solution is to use a leaky mold: the holes on the leaky mold correspond to the tablets on the film.

[0081] The solution of the present embodiment is to first cut the aluminum film of the film to reduce the pressure when pressing the tablets. When pressing the tablets, first press the edges of the film to make the surrounding film of the tablets have sufficient support force, so that the film does not deform greatly when pressed, and then press the tablets to press them out. The specific method is as follows.

[0082] (1) Adjust the distance between the movable baffles according to the width of the film;

[0083] (2) The first conveying roller mechanism conveys the film to the slit mechanism;

[0084] (3) The blade of the slit mechanism cuts the aluminum film of the blister into slits;

[0085] (4) The first and second conveying roller mechanisms convey, turn over and convey the film to the medicine pressing mechanism;

[0086] (5) The medicine pressing mechanism moves downward, and the tablet pressing rod presses the tablets on the blister to fall into the medicine bucket;

[0087] (6) The second conveying roller mechanism conveys the waste film to the end of the roller, and the waste film falls into the waste bucket.

[0088] It should be noted that the characteristics of the aluminum plastic plate medicine plate are: multiple specifications and sizes, different sizes and arrangements of the contained medicine tablets, and some medicine tablets have special functional protective films on the surface which cannot be damaged during peeling. The existing aluminum plastic plate medicine tablet peeling device cannot or hardly meet these characteristics.

[0089] The aluminum plastic plate medicine tablet peeling device has adjustable movable baffle positioning, densely arranged elastic pressure rod matrix combination pressure out mode, and knife blade opening mechanism, which can fully meet the above characteristics of the aluminum plastic plate medicine plate.

[0090] 1. It meets the characteristics of multiple specifications and sizes of aluminum plastic plate medicine plate, different sizes and arrangements of contained medicine tablets.

[0091] The existing aluminum plastic plate medicine tablet peeling device requires multiple sets of material leakage bottom plates according to the specified medicine plate size specifications, and the machine needs to be stopped and the material leakage bottom plate needs to be replaced when changing the medicine plate.

[0092] The device does not require a material leakage bottom plate and other standby devices, and only one set of movable baffles is used to complete this action. Before starting or during operation, the distance between the two movable baffles is adjusted according to the width of the input aluminum plastic plate. It can simultaneously meet the requirements of the width of the medicine plate input port, the working width of the conveying roller, the working width of the aluminum plastic plate medicine plate opening mechanism, and the working width of the aluminum plastic plate medicine plate pressing mechanism, and can ensure that the above mechanisms can reliably and effectively complete the expected actions.

[0093] 2. Especially the elastic pressure rod combination and adjustable structure of the aluminum plastic plate medicine plate pressing mechanism, and the densely arranged pressure rod pressure out mode. Regardless of the size of the medicine plate, the size of the medicine tablet, and the arrangement of the medicine tablet, the pressure rod can simultaneously act on the edge of the medicine plate and the medicine tablet, so that the edge of the medicine plate is pressed tightly and the medicine tablet is pressed out.

[0094] 3. Especially the knife blade combination and adjustable structure of the aluminum plastic plate medicine plate opening mechanism. Regardless of the size of the medicine plate, the size of the medicine tablet, and the arrangement of the medicine tablet, the densely arranged knife blades can cut the aluminum film on the surface of the aluminum plastic plate medicine plate into a slit. Then, the densely arranged elastic pressure rods on the aluminum plastic plate medicine plate pressing device can push the medicine tablet out with relatively small pressure without damaging the functional protective film on the surface of the medicine tablet.

[0095] In a specific embodiment, two kinds of aluminum plastic plate medicine plates with specifications of 102×42㎜(8×3=24 tablets / plate) and 121×64㎜(5×3=15 tablets / plate) are selected to implement medicine tablet peeling operations in sequence, and the main process is as follows:

[0096] (1) The operator directly places the 102×42㎜ medicine plate (bubble cap downward) between the movable baffles at the input port of the feeding hopper, rotates the hand wheel to move the movable baffles until the medicine plate (width direction) is close to being stuck (with a 1㎜ gap).
