[0001] This utility model relates to the field of pharmaceutical production technology, and in particular to a stamping structure for pharmaceutical aluminum foil packaging. Background Technology

[0002] Aluminum foil has excellent barrier properties, which can effectively prevent medicines from getting damp, wet and oxygenated, thereby keeping the medicines dry and stable. This is especially important for many medicines that are sensitive to humidity and oxygen, ensuring that they retain their active ingredients and efficacy within their shelf life. Aluminum foil is generally bonded to the surface of the plastic sheet used to hold the tablets using a stamping technique.

[0003] When stamping aluminum foil, the plastic sheet containing the pills is first placed on the mold and heated to soften it. Then, the aluminum foil is placed on top of the softened plastic sheet, and the stamping equipment is started to bond the aluminum foil to the plastic sheet. However, after the aluminum foil is bonded, the plastic sheet tends to stick to the top of the mold and is not easy to remove. It can only be removed after the plastic sheet has completely cooled and solidified, which affects the production efficiency. Utility Model Content

[0004] To overcome the problem that after the aluminum foil is bonded, the plastic sheet needs to be completely cooled and set before it can be removed, which affects production efficiency.

[0020] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please see Figure 1- Figure 6 This utility model provides an embodiment of a pharmaceutical aluminum foil packaging stamping structure, including a base plate 1, a heat-conducting plate 2, a plastic sheet positioning mold 3, and a stamping head 4. The heat-conducting plate 2 is fixedly connected to the upper end of the base plate 1, and the plastic sheet positioning mold 3 is provided at the upper end of the base plate 1. The plastic sheet positioning mold 3 is slidably connected to the heat-conducting plate 2. The stamping head 4 for pressing aluminum foil is provided above the plastic sheet positioning mold 3. A metal piston 5 is slidably connected inside the plastic sheet positioning mold 3. Two racks 12 are fixedly installed on both sides of the plastic sheet positioning mold 3. A bearing seat 13 is fixedly installed on the upper end of one side of the heat-conducting plate 2. A gear 14 is rotatably arranged between the two bearing seats 13. A rack 10 is meshed on one side of the gear 14. The rack 12 is meshed with the gear 14. A top block 19 for lifting the metal piston 5 is provided at the upper end of the base plate 1. A cooling component for cooling the plastic sheet is provided on the surface of the base plate 1. During stamping, the cooling component cools the plastic sheet inside the plastic sheet positioning mold 3. The heated plastic sheet is placed on the upper end of the plastic sheet positioning mold 3, and then the aluminum foil is placed on the upper end of the plastic sheet. The stamping equipment is then started. During the stamping process, the stamping head 4 presses the aluminum foil and the softened plastic sheet together, thus connecting the aluminum foil and the plastic sheet. The medicine is thus sealed inside the plastic sheet. The medicine can be removed by puncturing the aluminum foil. During the stamping process, the rack 10 fixed at both ends of the fixed plate 11 moves downward at the same time. The rack 10 meshes with the gear 14, and the gear 14 rotates at the bearing seat 13. The rack 2 12 drives the plastic sheet positioning mold 3 upward, thus completing the stamping. After the stamping is completed, the stamping head 4 moves upward, and the plastic sheet positioning mold 3 moves downward. The top block 19 provided at the upper end of the bottom plate 1 pushes the metal piston 5 slidably provided in the plastic sheet positioning mold 3 upward, thereby pushing the plastic sheet out of the plastic sheet positioning mold 3. This facilitates the quick removal of the plastic sheet and improves production efficiency.

[0022] Please see Figure 2 - Figure 4In this embodiment, a connecting shaft 9 for connecting the stamping equipment is provided above the base plate 1. A fixing plate 11 is fixedly connected to the lower end of the connecting shaft 9. The stamping head 4 is fixedly installed at the lower end of the fixing plate 11. A rack 10 is fixedly installed at both ends of the fixing plate 11. Side grooves 8 are provided on both sides of the upper end of the plastic sheet positioning mold 3. Blades 20 for cutting aluminum foil are provided on both sides of the lower end of the stamping head 4. The side grooves 8 are adapted to the blades 20. Holes for the top block 19 to pass through are evenly distributed at the lower end of the plastic sheet positioning mold 3. An internal threaded hole 7 is provided inside the plastic sheet positioning mold 3. A magnetic ring 6 for pulling the metal piston 5 is fixedly installed at the internal threaded hole 7 by bolts. A distance is provided between the two heat-conducting plates 2. The heat-conducting plates 2 are used for heat conduction and limiting. The magnetic ring 6 is used to pull the metal piston 5 downward. After stamping, it is ensured that the metal piston 5 returns to its original position to prevent the plastic sheet from being unable to be smoothly put into the plastic sheet positioning mold 3. A distance is provided between the heat-conducting plates 2 to facilitate the removal of the stamped drug packaging from the plastic sheet positioning mold 3.

[0023] Please see Figure 3 and Figure 6 In this embodiment, the cooling assembly includes a guide pipe 17, and through holes 18 are evenly distributed in the base plate 1. The guide pipe 17 is installed in the through holes 18. Water chambers 15 are fixedly installed on both sides of the base plate 1. A water pipe interface 16 is provided at one end of the water chamber 15. The lower end of the plastic sheet positioning mold 3 is in contact with the upper surface of the base plate 1, and the side of the plastic sheet positioning mold 3 is in contact with the surface of the heat-conducting plate 2. Cooling water circulates between the two water chambers 15 and the guide pipe 17, thereby cooling the plastic sheet in the plastic sheet positioning mold 3. When the plastic sheet positioning mold 3 is attached to the upper surface of the base plate 1, the cooling water in the guide pipe 17 directly cools the plastic sheet. When the plastic sheet positioning mold 3 moves upward, the cooling water is transferred to the plastic sheet through the heat-conducting plate 2 to cool the plastic sheet.

[0024] In use, first place the heated plastic sheet on the upper end of the plastic sheet positioning mold 3, then place the aluminum foil on the upper end of the plastic sheet, and then start the stamping equipment. The connecting shaft 9 is used to connect the stamping equipment. During the stamping process, the stamping head 4 presses the aluminum foil and the softened plastic sheet together, thereby connecting the aluminum foil and the plastic sheet together. The medicine is thus sealed in the plastic sheet. The medicine can be taken out by puncturing the aluminum foil.

[0025] During the stamping process, the stamping head 4 is fixedly installed at the lower end of the fixed plate 11. The rack 10, which is fixedly connected to both ends of the fixed plate 11, moves downwards simultaneously. The rack 10 meshes with the gear 14, which rotates at the bearing seat 13. The gear 14 meshes with the rack 2 12, which is fixedly installed on both sides of the plastic sheet positioning mold 3. The rack 2 12 drives the plastic sheet positioning mold 3 upwards, thereby completing the stamping. After the stamping is completed, the stamping head 4 moves upwards, and the plastic sheet positioning mold 3 moves downwards. The top block 19 provided at the upper end of the base plate 1 pushes the metal piston 5, which is slidably provided inside the plastic sheet positioning mold 3, upwards, thereby pushing the plastic sheet out of the plastic sheet positioning mold 3. This facilitates the quick removal of the plastic sheet and improves production efficiency.

[0026] Water chambers 15 are fixedly installed on both sides of the base plate 1. Before stamping, water pipes are first connected to water pipe interfaces 16 provided at one end of the water chamber 15. Cooling water circulates between the two water chambers 15 and the guide pipe 17, thereby cooling the plastic sheet in the plastic sheet positioning mold 3, improving the cooling and forming rate of the plastic sheet, and further improving production efficiency.

[0027] The magnetic ring 6, which is fixedly installed at the built-in threaded hole 7, is used to pull the metal piston 5 downward. After the stamping is completed, when the plastic sheet positioning mold 3 moves upward, it ensures that the metal piston 5 returns to its original position, preventing the plastic sheet from being unable to be smoothly placed into the plastic sheet positioning mold 3.

[0028] When the blade 20 is stamped, it enters the side grooves 8 provided on both sides of the plastic sheet positioning mold 3 to cut the aluminum foil. After the aluminum foil is stamped, there is a distance between the heat conduction plates 2 to facilitate the removal of the stamped drug packaging from the plastic sheet positioning mold 3.

[0029] Through the above steps, the cooling process increases the rate of plastic sheet cooling and forming. After stamping, the plastic sheet is quickly ejected from the plastic sheet positioning mold 3, thereby improving production efficiency.
