Description

Technical Field

[0001] The present invention relates to the technical field of pharmaceutical processing, and particularly relates to a sealing machine for pharmaceutical processing. Background Art

[0002] A sealing machine for pharmaceutical processing is a device specifically used for sealing pharmaceutical containers in the pharmaceutical packaging process. Its main function is to ensure the tightness of the pharmaceutical containers, thereby preventing the medicine from being affected by moisture, contamination or leakage, and maintaining the quality and efficacy of the medicine.

[0003] The prior art document with the publication number CN211034044U provides a sealing machine for pharmaceutical processing, which adds a guide post, a fixed cylinder, an adjustment box, a left inclined rod, a right inclined rod, a ball screw, a compression spring, a first sliding seat, a bearing seat and a second sliding seat. This design enables the conveying structure in the sealing machine to have a height adjustment function, solves the problem that the conveying structure in the original sealing machine does not have a height adjustment function, and improves the convenience of adjusting the conveying structure of the sealing machine of the present utility model.

[0004] However, although the prior art has improvements in the adjustment of the conveying structure, there are still deficiencies in the limit treatment of the sealing of the blister packaging board for medicines. The sealing of the blister packaging board for medicines is to ensure the tightness of the medicine, protect the medicine from external contamination (such as air, moisture, light, etc.), and at the same time facilitate the patient to take the medicine. The sealing process of the blister packaging usually seals the tablets in the blister with a sealing layer (such as aluminum foil, paper film, etc.). The prior art is not convenient for limiting the blister packaging board. During sealing, not only will the blister packaging board be misaligned, but also the part of the blister packaging board containing the medicine will be deformed under pressure, resulting in the breakage of the medicine and affecting its sealing effect.

[0005] In summary, in the prior art, there is a lack of technology for limiting and sealing the blister packaging board containing medicines. Summary of the Invention

By providing a jitter mechanism, before sealing the blister packaging board, it can help the medicine be better fixed in the blister groove before heat sealing, avoiding the displacement of the medicine during the sealing process, and ensuring that the medicine is accurately located at the predetermined position. Especially for irregularly shaped or light medicines, the jitter mechanism helps the medicine maintain the correct placement state because only in the correct state can the medicine be evenly placed in the blister groove, reducing the risk of medicine damage caused by pressure concentration in a certain area and improving the sealing quality. 3. By providing a shielding and preheating mechanism, it can cover the blister packaging board with medicine before sealing and preheat the blister packaging board using the preheating ring. While ensuring the sealing quality of the medicine, it can effectively reduce the influence of air, moisture, or pollutants on the medicine before sealing, thereby extending the shelf life of the medicine, enhancing the stability and consistency of the sealing process. It not only helps improve the sealing quality but also reduces the risk of medicine deformation caused by external factors, thus improving the production efficiency, extending the shelf life of the medicine, and enhancing the aesthetics and safety of the packaging.

Detailed implementation manners

[0019] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations.

[0020] As Figures 1 - 8 shown, a sealing machine for drug processing includes a frame 1, a fixed seat 2 is fixedly connected to the frame 1, a heat-sealing pressing plate 3 is slidably fitted on the fixed seat 2, a transmission mechanism 4 is rotatably connected to the frame 1, a conveyor belt 5 is rotatably connected to the frame 1, a plurality of fixed frames 6 are fixedly connected to the conveyor belt 5, a placement seat 7 is fixedly connected to the fixed frame 6, a shielding and preheating mechanism 8 is slidably fitted on the placement seat 7, and a shaking mechanism 9 is rotatably connected to the fixed frame 6.

[0021] As Figure 3 shown, a feeding chute 101 is opened on the lower side of the frame 1, a guiding ring 102 is fixedly connected to one inner wall of the frame 1, a groove 103 is opened on the guiding ring 102, a support plate 104 is fixedly connected to the middle inner wall of the guiding ring 102, the support plate 104 is in sliding contact with the conveyor belt 5, and a fixed rack 105 is fixedly connected to one inner wall of the frame 1 on the side of the guiding ring 102. The support plate 104 supports the conveyor belt 5 when the heat-sealing pressing plate 3 performs sealing.

[0022] AsFigure 4 As shown, an electric push rod 301 is fixedly connected to the heat-sealing pressing plate 3. The electric push rod 301 is fixedly connected to the fixed seat 2. One end of the heat-sealing pressing plate 3 is fixedly connected with a transmission rack 302. The electric push rod 301 is used to drive the heat-sealing pressing plate 3 to move downward to seal the blister packaging plate 702. At this time, the transmission rack 302 connected to the heat-sealing pressing plate 3 will drive the end face gear B404 connected to the transmission wheel 405 to rotate.

[0023] As Figure 5 As shown, the transmission mechanism 4 includes a transmission rod 401. One end of the transmission rod 401 is rotatably connected to the frame 1 through penetration. Belt pulleys 501 are frictionally driven on the inner walls at both ends of the conveyor belt 5. The belt pulleys 501 are rotatably connected to the frame 1. One of the belt pulleys 501 is fixedly connected to the transmission rod 401. An end face gear A402 is slidably fitted on the outer wall of the other end of the transmission rod 401. A spring A403 is fixedly connected to one side of the end face gear A402. The other end of the spring A403 is fixedly connected to the transmission rod 401. An end face gear B404 is movably meshed and driven on one side of the end face gear A402. The end face gear B404 is rotatably connected to the frame 1. A transmission wheel 405 is fixedly connected to one side of the end face gear B404. The transmission wheel 405 is meshed and driven with the transmission rack 302. The teeth on the end face gear B404 will contact the inclined surface of the teeth on the end face gear A402, so that the end face gear A402 will not be driven to rotate. Then, when the heat-sealing pressing plate 3 moves upward and the end face gear B404 rotates in the reverse direction, at this time, the teeth on the end face gear B404 will contact the flat surface of the teeth on the end face gear A402, so that the end face gear A402 will be driven to rotate, causing the end face gear A402 to drive the belt pulley 501 connected to the transmission rod 401 to rotate, and the belt pulley 501 drives the conveyor belt 5 to rotate.

[0024] As Figure 6 As shown, a positioning groove 701 is formed on the placing seat 7. A blister packaging plate 702 is placed on the placing seat 7. The convex part of the blister packaging plate 702 is adapted to the positioning groove 701.

[0025] By forming the positioning groove 701 on the placing seat 7, it is convenient to position the blister packaging plate 702, effectively ensuring the stability of the blister packaging plate 702 during the sealing process, preventing the medicine part from being affected by uneven pressure or excessive temperature, thereby avoiding the deformation of the packaging plate, and then ensuring the sealing quality, the integrity of the medicine and the production efficiency. It not only improves the accuracy in the production process, but also improves the appearance quality of the product, reduces the waste products and lowers the production cost at the same time, having significant advantages.

[0026] As Figure 7As shown in the figure, the shielding and preheating mechanism 8 includes a guiding contact head 801 which is slidably in contact with the outer wall of the guiding ring 102. On one side of the guiding contact head 801, two pull rods 802 are rotatably connected symmetrically. The other ends of the pull rods 802 are rotatably connected to a slider 803 which is slidably engaged with the placement seat 7. A tension spring 807 is fixedly connected to one side of the slider 803, and the other end of the tension spring 807 is fixedly connected to the placement seat 7. When the conveyor belt 5 drives the placement seat 7 to move, at this time, the guiding contact head 801 will move from the guiding ring 102 to the groove 103. At this time, under the action of the tension spring 807, the shielding plate 804 connected to the slider 803 will be driven to move.

[0027] A shielding plate 804 is fixedly connected to the slider 803. A plurality of preheating rings 805 are fixedly connected to the lower surface of the shielding plate 804, and an electric heating wire 806 is fixedly connected to the inner wall of the shielding plate 804. The electric heating wire 806 is used to heat the preheating rings 805. At this time, the preheating rings 805 will preheat the blister packaging board 702.

[0028] As Figure 8 shown in the figure, the jitter mechanism 9 includes an adjusting wheel 901 which is rotatably connected to the fixed frame 6 through a pin shaft. The adjusting wheel 901 is in meshing transmission with the fixed rack 105. A driving wheel 902 is fixedly connected to one side of the adjusting wheel 901. A driven wheel 903 is in meshing transmission with one side of the driving wheel 902. A rotating shaft 904 is fixedly connected to the driven wheel 903, and the rotating shaft 904 is rotatably connected to the fixed frame 6. A plurality of shifting rods 905 are fixedly connected to the outer wall of the rotating shaft 904 at different angles.

[0029] One end of the shifting rod 905 is slidably in contact with a movable rod 906 which is slidably engaged with the fixed frame 6. A spring B907 is fixedly connected to the bottom end of the movable rod 906, and the other end of the spring B907 is fixedly connected to the fixed frame 6. The top end of the movable rod 906 is movably in contact with the lower surface of the placement seat 7. Under the action of the fixed rack 105, the adjusting wheel 901 will rotate. At this time, the adjusting wheel 901 will drive the connected driving wheel 902 to rotate, so that the driving wheel 902 drives the rotating shaft 904 connected to the driven wheel 903 to rotate, so that the rotating shaft 904 drives the connected shifting rods 905 to rotate, so that the shifting rods 905 will contact and push the movable rod 906 to move downward. When the shifting rods 905 are not in contact with the movable rod 906, under the action of the spring B907, the movable rod 906 will quickly move upward to contact the placement seat 7, causing the blister packaging board 702 on the placement seat 7 to generate jitter.

[0030] Working principle: When it is necessary to seal the blister packaging board 702 containing medicine, first place the blister packaging board 702 into the positioning groove 701 on the placing seat 7. Then, when the placing seat 7 is driven to move by the conveyor belt 5, at this time, the guiding contact head 801 will move from the guiding ring 102 to the groove 103. At this time, under the action of the tension spring 807, it will drive the baffle 804 connected to the slider 803 to move and block above the blister packaging board 702. Then, use the electric heating wire 806 to heat the preheating ring 805. At this time, the preheating ring 805 will preheat the blister packaging board 702. Then, when the placing seat 7 moves below the heat-sealing pressing plate 3, the guiding contact head 801 will move out of the groove 103, thereby causing the guiding contact head 801 to drive the slider 803 connected to the pull rod 802 to move, and the baffle 804 to move away; At the same time, during the process of the placing seat 7 moving below the heat-sealing pressing plate 3, under the action of the fixed rack 105, the adjusting wheel 901 will rotate. At this time, the adjusting wheel 901 will drive the connected driving wheel 902 to rotate, causing the driving wheel 902 to drive the rotating shaft 904 connected to the driven wheel 903 to rotate, causing the rotating shaft 904 to drive the connected lever 905 to rotate, and the lever 905 will contact and push the movable rod 906 to move downward. When the lever 905 is not in contact with the movable rod 906, under the action of the spring B907, the movable rod 906 will quickly move upward to contact the placing seat 7, causing the blister packaging board 702 on the placing seat 7 to vibrate, so that the medicine in the blister packaging board 702 can fall to the appropriate position and avoid deviation; After the blister packaging board 702 moves below the heat-sealing pressing plate 3, use the electric push rod 301 to drive the heat-sealing pressing plate 3 to move downward to seal the blister packaging board 702. At this time, the transmission rack 302 connected to the heat-sealing pressing plate 3 will drive the end face gear B404 connected to the transmission wheel 405 to rotate. At this time, the teeth on the end face gear B404 will contact the inclined surface of the teeth on the end face gear A402, so it will not drive the end face gear A402 to rotate. Then, when the heat-sealing pressing plate 3 moves upward, the end face gear B404 will rotate in the reverse direction. At this time, the teeth on the end face gear B404 will contact the flat surface of the teeth on the end face gear A402, thereby driving the end face gear A402 to rotate, causing the end face gear A402 to drive the belt pulley 501 connected to the transmission rod 401 to rotate, causing the belt pulley 501 to drive the conveyor belt 5 to rotate, and moving another blister packaging board 702 below the heat-sealing pressing plate 3. When the blister packaging board 702 moves below the conveyor belt 5, it will fall from the placing seat 7 and be discharged through the blanking chute 101.
