Abstract
Description
Technical Field
[0001] This utility model relates to the field of tablet packaging technology, and in particular to a moisture-proof sealing device for a tablet packaging machine. Background Technology
[0002] In tablet packaging, the medicine is often first placed into a bottle, and then the bottle opening is sealed with an aluminum foil composite film to prevent moisture. Currently, induction heating is used to heat-seal the aluminum foil composite film when sealing the bottle. However, existing induction heat-sealing devices often only have one type of induction heating coil of a fixed size, which can only be used for bottles of a specific diameter and is difficult to adapt to bottles of different diameters. Therefore, in view of the above situation, there is an urgent need to develop a moisture-proof sealing device for tablet packaging machines that can quickly seal and prevent moisture in bottles of different diameters using four non-metallic pressure plates of different sizes and induction heating coils, in conjunction with a rotary switching mechanism, to overcome the shortcomings of current practical applications and meet current needs. Utility Model Content
[0003] The purpose of this invention is to provide a moisture-proof sealing device for a tablet packaging machine to solve the problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:
[0005] A moisture-proof sealing device for a tablet packaging machine includes a worktable, a vertical plate, a turntable, an induction heating sealing mechanism, and a rotation switching mechanism. The vertical plate is fixedly installed on the worktable, the turntable is located on the front side of the vertical plate, and a support shaft is fixed to the rear side of the turntable. The support shaft is rotatably connected to the vertical plate. The rotation switching mechanism is installed on the vertical plate and is used to drive the support shaft to rotate. The induction heating sealing mechanism includes: an electric telescopic rod, a base plate, a non-metallic pressure plate, and an induction heating coil. There are four electric telescopic rods, four base plates, four non-metallic pressure plates, and four induction heating coils. The four electric telescopic rods are evenly distributed in a circle and fixed on the turntable. The telescopic end of each electric telescopic rod is fixed to a base plate. Each non-metallic pressure plate is fixed to a base plate. An induction heating coil is provided on the outer side of each non-metallic pressure plate. Each induction heating coil is fixedly installed on a base plate. The diameters of the four non-metallic pressure plates are different, and the inner diameters of the four induction heating coils are different.
[0006] Preferably, the rotation switching mechanism includes a servo motor, a first gear, and a second gear. The servo motor is fixed to the upright plate, and the first gear is fixed on the output shaft of the servo motor. A second gear is provided on one side of the first gear to mesh with it, and the second gear is fixed on the support shaft.
[0007] Preferably, an annular slide rail is fixed on the upright plate, and multiple sliders are slidably mounted on the annular slide rail, with the sliders fixedly mounted on the rear side of the turntable.
[0008] Preferably, both the substrate and the non-metallic pressure plate are made of polytetrafluoroethylene.
[0009] Preferably, a PLC controller is fixedly installed on the workbench, and the electric telescopic rod, induction heating coil and servo motor are all controlled by the PLC controller.
[0010] The beneficial effects of this utility model are as follows: The moisture-proof sealing device of this tablet packaging machine, when in use, selects a non-metallic pressure plate and induction heating coil that match the different diameters of the medicine bottles. During selection, a servo motor drives the first and second gears to rotate, which in turn drives the support shaft and turntable to rotate. The turntable then rotates and repositions the four non-metallic pressure plates and four induction heating coils, ensuring that the required size non-metallic pressure plate and induction heating coil are positioned directly below the turntable. The medicine bottle is then placed below the non-metallic pressure plate, and the aluminum foil composite film for sealing is placed at the bottle opening. An electric telescopic rod then moves the base plate, non-metallic pressure plate, and induction heating coil downwards, causing the non-metallic pressure plate to press the aluminum foil composite film tightly onto the medicine bottle. Simultaneously, the induction heating coil induction heats the aluminum foil composite film, causing the heat-sealing layer of the aluminum foil composite film to adhere and fix to the bottle opening, thereby achieving a moisture-proof seal for the medicine bottle. In summary, this utility model, through four non-metallic pressure plates of different sizes and induction heating coils, combined with a rotary switching mechanism, can quickly seal and prevent moisture from medicine bottles of different diameters, thus having a wider range of applications.

The support shaft 301 is rotatably connected to the vertical plate 2. The rotation switching mechanism 5 is installed on the vertical plate 2 and is used to drive the support shaft 301 to rotate. The rotation switching mechanism 5 drives the support shaft 301 and the turntable 3 to rotate 90° each time. The induction heating sealing mechanism 4 includes: an electric telescopic rod 401, a base plate 402, a non-metallic pressure plate 403, and an induction heating coil 404. The electric telescopic rod 401, the base plate 402, the non-metallic pressure plate 403, and the induction heating coil 404... There are four electric telescopic rods 401, which are evenly distributed in a circle and fixed on the turntable 3. The telescopic end of each electric telescopic rod 401 is fixed to a base plate 402. Each non-metallic pressure plate 403 is fixed to a base plate 402. The non-metallic pressure plate 403 is used to press the aluminum foil composite film (composed of aluminum foil, heat sealing layer and support layer) at the mouth of the medicine bottle. Each non-metallic pressure plate 403 has an induction heating coil 404 on its outer side. The induction heating coil 404 is used to induction heat the aluminum foil of the aluminum foil composite film. Each induction heating coil 404 is fixedly installed on a base plate 402. The diameters of the four non-metallic pressure plates 403 are different, and the inner diameters of the four induction heating coils 404 are different, so as to seal medicine bottles of different diameters.
[0021] The rotary switching mechanism 5 includes a servo motor 501, a first gear 502, and a second gear 503. The servo motor 501 is fixed on the vertical plate 2. The first gear 502 is fixed on the output shaft of the servo motor 501. A second gear 503 is provided on one side of the first gear 502 and meshes with it. The second gear 503 is fixed on the support shaft 301. The transmission ratio of the first gear 502 and the second gear 503 is 1:1. The output shaft of the servo motor 501 rotates 90° each time. In use, the servo motor 501 drives the first gear 502 and the second gear 503 to rotate, and the second gear 503 drives the support shaft 301 and the turntable 3 to rotate.
[0022] An annular slide rail 6 is fixed on the upright plate 2, and multiple sliders 601 are slidably installed on the annular slide rail 6. The sliders 601 are fixedly installed on the rear side of the turntable 3.
[0023] A PLC controller 7 is fixedly installed on the workbench 1. The electric telescopic rod 401, the induction heating coil 404 and the servo motor 501 are all controlled by the PLC controller 7.
[0024] The substrate 402 and the non-metallic pressure plate 403 are both made of polytetrafluoroethylene, which gives them good high temperature resistance and prevents induction heating.
[0025] Working Principle: The moisture-proof sealing device of this tablet packaging machine, during use, selects the appropriate non-metallic pressure plate 403 and induction heating coil 404 according to the different diameters of the medicine bottles. During selection, the servo motor 501 drives the first gear 502 and the second gear 503 to rotate. The second gear 503 drives the support shaft 301 and the turntable 3 to rotate. The turntable 3 then rotates and repositions the four non-metallic pressure plates 403 and the four induction heating coils 404, ensuring that the required size non-metallic pressure plate 403 and induction heating coil 404 are directly below the turntable 3. Then, the medicine bottle is placed under the non-metallic pressure plate 403, and the aluminum foil composite film (composed of aluminum foil, heat-sealing layer and support layer) for sealing is placed at the mouth of the medicine bottle. Then, the electric telescopic rod 401 drives the base plate 402, the non-metallic pressure plate 403 and the induction heating coil 404 to move down, so that the non-metallic pressure plate 403 presses the aluminum foil composite film onto the medicine bottle. At the same time, the induction heating coil 404 induction heats the aluminum foil composite film, and the induction heating causes the heat-sealing layer of the aluminum foil composite film to adhere and fix to the mouth of the bottle, thereby achieving a seal and moisture protection for the medicine bottle.
