Description

Technical Field

[0001] The invention relates to the technical field of medicine packaging, in particular to a medicine plate cooling and leveling device for a blister machine. Background Art

[0002] Pharmaceutical packaging is extremely important for maintaining the performance of drugs. Blister packaging machines use transparent plastic films or sheets to form blisters, and use heat sealing, gluing, and other methods to seal the product between the blister and the base. Blister packaging machines are mainly used to package solid drugs and foods such as capsules, tablets, pills, suppositories, milk tablets, candies, and small hardware. They can isolate moisture and light, strengthen the seal, and avoid light, thereby ensuring the performance of the drug and extending its shelf life.

[0003] During the operation of the blister machine, the formed film is heated and softened by the heating device and then sucked out of the blister through vacuum negative pressure. The temperature is relatively high. If the temperature is not lowered in time, the effect of the subsequent drug will be affected. Therefore, during the operation of the blister machine, the moving distance of the blister is usually extended to allow it to come into contact with the outside air, thereby cooling naturally.

[0004] However, due to the volume limitation of the blister machine, its moving distance cannot be set to be longer. If the blister is moved over a shorter distance, the cooling effect is poor, which in turn affects the shaping effect. If the blister is moved over a longer distance, the volume of the blister machine occupies too much space. Therefore, the present invention proposes a blister machine medicine plate cooling and leveling device to solve the problems existing in the prior art. Summary of the Invention

[0021] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the examples. The examples are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0022] according to Figure 1 - Figure 5 As shown, this embodiment proposes a device for cooling and leveling medicine plates for a blister machine, comprising a hollow base 1. The hollow base 1 itself is composed of two parts, namely an upper part and a lower part. That is, the cross-section of the hollow base 1 is in the shape of an inverted convex letter "U", and the length and width of the upper part are greater than those of the lower part. This facilitates the installation of the hollow base 1 on a workbench for connection with the blister machine. When the blister machine is in operation, the medicine plate strip is pre-heated and then directly passes through the cooling and leveling device before entering subsequent operations such as loading.

[0023] Specifically, an assembly frame 2 is provided above the hollow base 1, and an assembly shell 3 is provided on the inner side of the assembly frame 2. The cross-section of the assembly frame 2 is arranged in a U-shape, and an assembly shell 3 is provided on the inner side thereof. Specifically, an electric push rod 20 is installed on the assembly frame 2 above the assembly shell 3, and the telescopic end of the electric push rod 20 is connected to the assembly shell 3, so that the height of the assembly shell 3 can be adjusted to adapt to the medicine plate belts of different heights of the blister machine, thereby improving the practicality of the device.

[0024] A leveling component is installed on the assembly shell 3, wherein the leveling component includes a leveling cylinder 10, and the leveling cylinder 10 is evenly arranged in multiple groups. In this embodiment, there are five groups of leveling cylinders 10, and the outer sides of the five groups of leveling cylinders 10 are all provided with openings on the assembly shell 3, that is, it can be understood that an opening is provided at the lower end of the assembly shell 3, and there are five groups of openings, which are connected to the outside world and the inner cavity of the assembly shell 3, and then a leveling cylinder 10 is provided on the inner side of the opening, and the leveling cylinder 10 itself carries a shaft for connection, and then the inner side of the opening is connected to the leveling cylinder 10 axis through a bearing, and the corresponding two ends of the leveling cylinder 10 are connected to the assembly shell 33 through a bearing, and then the lower part of the leveling cylinder 10 is located below the assembly shell 3, thereby, the medicine plate is given a downward direction from the top through the multiple groups of leveling cylinders 10. force, and cooperates with the subsequent support seat 4 to level the medicine strip. Specifically, second fans 11 are installed on both sides above the assembly shell 3. The second fans 11 on both sides are oppositely arranged. The assembly shell 3 itself is hollow. Correspondingly, since the medicine strip enters the device directly after being heated, it itself will have a certain amount of heat. Therefore, the leveling cylinder 10 may absorb a certain amount of heat during the leveling process, and then the two groups of second fans 11 set in opposite directions are set to make the external air pass through the second fan 11 on one side and then be discharged by the second fan 11 on the other side. In the process of passing, it contacts the leveling cylinder 10 to take away the heat absorbed by the leveling cylinder 10, and then the leveling cylinder 10 itself contacts the medicine strip, which can also have a certain cooling effect.

[0025] A support base 4 is provided directly below the assembly housing 3, and a channel 5 is provided on the support base 4, and the channel 5 is evenly provided with multiple groups, such as Figure 2 As shown, in this embodiment, there are five groups of channels 5, which are adapted to the blisters on the medicine strip, that is, the channels 5 can accommodate the blisters on the medicine strip, and then when the blisters pass through, they can also play a limiting role on them, and a lower shell 6 is installed at the lower end of the hollow base 1, and the inner cavity of the lower shell 6 is connected to the inner cavity of the hollow base 1, and a first fan 7 is installed in the lower shell 6, and a refrigerator 8 is provided below the first fan 7, and the refrigerator 8 is connected to the lower shell 6 through a bracket, and air inlets 9 are provided on both sides of the lower shell 6 below the refrigerator 8. Before work, the refrigerator 8 is started first to pre-cool the air in the lower shell 6, and then when working, the first fan 7 is started, and the cold air is transported to the support seat 4 by the first fan 7. Since the upper end of the support seat 4 passes through the medicine strip, it is cooled by contact with the cold air, and then the flattening cylinder 10 and the support seat 4 cooperate to perform a flattening operation on it.

[0026] Specifically, the inner side of the lower shell 6 is provided with two groups of insulation plates 12 symmetrically arranged in an upper and lower manner. The outer side of the insulation plate 12 is connected to the lower shell 6, and then the inner cavity of the lower shell 6 is divided into multiple groups. The two groups of insulation plates 12 are connected to the refrigerator 8, and the insulation plates 12 are provided with air vents 13, and the outer side of the refrigerator 8 is provided with an insulation shell 14. The insulation shell 14 is cylindrical, and the refrigerator 8 is mounted on its inner side, while the outer side is connected to the lower shell 6. Thus, an insulated inner cavity is formed by the arrangement of the insulation shell 14 and the insulation plates 12 on both sides, which prevents the external temperature from affecting the temperature of the inner cavity, and also prevents the temperature of the inner cavity from affecting the outside. The outer side of the specific insulation shell 14 is in contact with the inner side of the lower shell 6, and the upper and lower ends of the insulation shell 14 are in contact with the upper and lower insulation plates 12 respectively.

[0027] A limiting cylinder 15 is provided on the inner side of the hollow base 1. The upper end of the limiting cylinder 15 passes through the hollow base 1 and is connected to the support seat 4. The limiting cylinder 15 moves up and down in the hollow base 1. The limiting cylinder 15 is hollow, and a second filter element 21 is installed on the inner side of the limiting cylinder 15, so that the cold air can be filtered on the way through to avoid the influence of dust particles and the like on the dosing plate. Specifically, connecting holes 16 are provided on both sides of the limiting cylinder 15. There are multiple groups of connecting holes 16 from top to bottom. Pins 17 are provided on both sides of the limiting cylinder 15 on the hollow base 1. One end of the pin 17 passes through the hollow base 1 and is connected to the connecting hole 16 by a thread.

[0028] Furthermore, the lower heat insulation board 12 is located above the air inlet 9, and a filter box 18 is provided below the lower heat insulation board 12. Air inlets are provided on both sides of the filter box 18, and the positions of the air inlets correspond to the positions of the air inlet 9. An air outlet is provided on the filter box 18, and the positions of the air outlet correspond to the positions of the vents 13. A first filter element 19 is installed on the inner side of the filter box 18. Then, when the air enters between the heat insulation boards 12 on both sides, it first passes through the filter box 18 for preliminary filtering treatment to avoid the accumulation of dust and other foreign matter between the heat insulation boards 12 on both sides, which affects the air cooling effect.
