[0015] Figure 1 This is a diagram showing the usage state of this utility model;

[0016] Figure 2 This is a schematic diagram of the structure of this utility model;

[0017] Figure 3 This is a partial view of the present invention. Detailed Implementation

[0018] like Figure 1 As shown, this interlayer material feeding device includes a drop pipe 2 and a feed pipe 3. The feed pipe 3 is connected to the lower end of the drop pipe 2 (the two can be an integral structure or a separate structure). After the turnover bucket 1 containing granular materials is conveyed over, the material is placed into the drop pipe 2. The material falls through the drop pipe 2 and then enters the blister packaging machine 4 below through the feed pipe 3. The blister packaging machine 4 then packages the granular material into blister packs.

[0019] In order to control the falling speed of the material, such as Figure 2As shown, an elastic tube 5 (a tube with elasticity, such as a rubber hose, a silica gel hose, etc.) is arranged in the falling pipe 2, the upper end of the elastic tube 5 is connected at the upper port of the falling pipe 2, and the lower end of the elastic tube 5 is connected at the lower port of the falling pipe 2, an air inlet joint 20 is connected on the falling pipe 2, the air inlet joint 20 is connected with an air source, and in addition, a vacuum joint 21 is also connected on the falling pipe 2, the vacuum joint 21 is connected with a negative pressure source (the negative pressure source includes a vacuum pump, a vacuum generator, and other devices capable of generating negative pressure). In operation, the material in the turnover barrel 1 is lowered into the elastic tube 5, the air source supplies air to the falling pipe 2 through the air inlet joint 20, and the gas enters the space between the elastic tube 5 and the falling pipe 2, as the gas continues to increase, the elastic tube 5 gradually shrinks, and the passage of the elastic tube 5 gradually narrows, so that the falling speed of the material in the elastic tube 5 can be slowed down, thereby avoiding damage to the material due to a large drop; when the material in the elastic tube 5 is blocked, or the falling speed needs to be accelerated, or the initial state of the elastic tube 5 needs to be restored, the air supply of the air source is cut off, and the negative pressure source draws air through the vacuum joint 21 to exhaust the air between the elastic tube 5 and the falling pipe 2, so that the passage of the elastic tube 5 gradually increases.

[0020] By controlling the air inlet amount of the gas, the contraction of the elastic tube 5 can be accurately controlled, thereby accurately controlling the speed of the material falling; at the same time, since the air pressure in the falling pipe 2 is uniform, the air pressure acting on the elastic tube 5 can make the inner wall surface of the elastic tube 5 more smooth, even if the inner diameter of the falling pipe 2 becomes smaller and the falling speed of the material becomes slower, it can also ensure that all granular materials fall smoothly and will not be blocked or jammed.

[0021] As described above, the granular material is loaded in the turnover barrel 1, so the turnover barrel 1 is included; in order to automatically connect the turnover barrel 1 with the falling pipe 2, as shown, Figure 2 an air bag connecting mechanism 7 is connected at the upper end of the falling pipe 2, as shown, Figure 3 the air bag connecting mechanism 7 includes an air bag 70, an air bag seat 71, an air bag lifting power source 74, an extension tube 72 (made of flexible material, which can be extended up and down, such as a plastic film sleeve, a plastic corrugated tube, a rubber tube, a silica gel tube, etc.), and an extension tube connecting sleeve 73. The air bag 70 is connected to the air bag seat 71, and the upper end of the extension tube 72 is connected to the air bag seat 71, the lower end of the extension tube 72 is connected to the extension tube connecting sleeve 73, and the extension tube connecting sleeve 73 is arranged at the upper port of the falling pipe 2. After the turnover barrel 1 loaded with material comes, the air bag lifting power source 74 drives the air bag seat 71 to move up and down, so that the air bag 70 is sleeved at the discharge port 10 of the turnover barrel 1, and then the air bag 70 is inflated to wrap the discharge port 10 of the turnover barrel 1 to form a seal (to avoid the air in the space where the turnover barrel 1 is located from entering the elastic tube 5 below to pollute the material), so that the material in the turnover barrel 1 can be lowered into the elastic tube 5.

[0022] Some granular materials have powder on their surface (such as medicine granules), and powder is also produced by the friction between granular materials, which will fall on the inner wall of the telescopic tube 72, the telescopic tube connecting sleeve 73 and the elastic tube 5; when one kind of material is finished packaging and another kind of material is to be replaced, the powder of the former kind of material will stick to the latter kind of material, thus causing contamination of the material. In order to solve this problem, as shown in Figure 2 , a straight plastic film 6 is connected to the air bag seat 71, as shown in Figure 3 , which is located in the elastic tube 5, and the lower end of the straight plastic film 6 extends below the drop tube 2. In operation, the material in the turnover barrel 1 falls into the straight plastic film 6, and the material falls along the straight plastic film 6. When one kind of material is finished packaging and another kind of material is to be replaced, only the straight plastic film 6 needs to be replaced, so that the material will not contaminate the telescopic tube 72, the telescopic tube connecting sleeve 73 and the elastic tube 5, and different materials will not contaminate each other.

[0023] In order to facilitate the connection of the air bag connecting mechanism 7 with the drop tube 2, as shown in Figure 3 , the telescopic tube connecting sleeve 73 has a lower section, a middle section 730 and an upper section, the diameter of the lower section is smaller than that of the upper section, and the middle section 730 is a slope. When the air bag connecting mechanism 7 is placed, the lower section of the telescopic tube connecting sleeve 73 is placed into the drop tube 2, and the middle section 730 of the telescopic tube connecting sleeve 73 acts on the upper port of the drop tube 2. In this way, the air bag connecting mechanism 7 is very conveniently connected with the drop tube 2, and a seal is formed between the middle section 730 of the telescopic tube connecting sleeve 73 and the upper port of the drop tube 2.

[0024] As shown in Figure 3 , the lower end of the elastic tube 5 is connected outside the lower port of the drop tube 2, the upper end of the elastic tube 5 is connected outside the upper port of the drop tube 2, and the middle section 730 of the telescopic tube connecting sleeve 73 acts on the elastic tube 5. In this way, not only is the connection of the elastic tube 5 with the drop tube 2 facilitated, but also the seal between the drop tube 2 and the telescopic tube connecting sleeve 73 is stronger due to the presence of the elastic material (i.e. the elastic tube 5) between them.

[0025] As shown in Figure 2 , the feed tube 3 is connected with the lower sleeve 31 through the valve 30, and the lower sleeve 31 is connected with the lower end of the drop tube 2 (detachable connection, facilitating the installation and replacement of the elastic tube 5 and the arrangement of the straight plastic film 6). After the material is finished falling, the valve 30 is closed to avoid the air in the space where the turnover barrel 1 is located from entering the space below the bubble cap packaging machine 4 through the pipeline, causing contamination.

[0026] As shown in Figure 3 , a photoelectric sensor 8 is arranged at the upper port of the drop tube 2, as shown in Figure 1As shown, the photoelectric sensor 8 is electrically connected to the control center 9, and the control center 9 is connected to the alarm 90. When the photoelectric sensor 8 detects that no material is falling, it transmits a signal to the control center 9, which then controls the alarm 90 to sound an alarm (audible alarm and / or visual alarm) to notify the staff.

[0027] As described above, the turnover drum 1 is installed on the traveling trolley 12, which can conveniently transport the turnover drum 1 so that the discharge port of the turnover drum 1 can reach above the drop pipe 2. A material control valve 11 is installed at the discharge port of the turnover drum 1. When the turnover drum 1 is in place, the material control valve 11 can control the material to be released.

[0028] like Figure 2 As shown, the feed pipe 3 is located on the lower layer A, on the same layer as the blister packaging machine 4, while the turnover drum 1 is located on the upper layer C. This layer is specifically used for the production of granular materials. In this way, the workshop for producing materials and the workshop for packaging materials are separated, so that they do not affect or contaminate each other, and it is also convenient for material transportation between the two workshops. The air inlet connector 20 and the vacuum connector 21 are located on the middle layer B (the middle layer B is used to install various pipelines as well as air sources and negative pressure sources).

[0029] Finally, it's worth mentioning that the lower layer A is a cleanroom, and the upper layer C is a cleanroom. Cleanrooms are workshops that are not subject to external contamination.
