BRIEF DESCRIPTION OF THE DRAWINGS
[0015] Figure 1 is a use state diagram of the present invention; Figure 2 is a structural schematic diagram of the present invention; Figure 3 is a partial view of the present invention. DETAILED DESCRIPTION OF THE INVENTION
[0016] As Figure 1 shown, this interlayer blanking device includes a falling tube 2 and a feed pipe 3. The feed pipe 3 is connected to the lower end of the falling tube 2 (the two can be an integral structure or a split structure). After the turnover barrel 1 containing granular materials is transported, the materials are put into the falling tube 2. The materials fall through the falling tube 2 and then enter the lower blister packaging machine 4 through the feed pipe 3. The blister packaging machine 4 packs the granular materials in the blister board.
[0017] In order to control the falling speed of the material, as Figure 2As shown in the figure, an elastic tube 5 (a tube with elasticity, such as a rubber hose, a silicone hose, etc.) is provided inside the downcomer 2. The upper end of the elastic tube 5 is connected to the upper port of the downcomer 2, and the lower end of the elastic tube 5 is connected to the lower port of the downcomer 2. An air inlet joint 20 is connected to the downcomer 2, and the air inlet joint 20 is connected to a gas source. In addition, a vacuum joint 21 is also connected to the downcomer 2, and the vacuum joint 21 is connected to a negative pressure source (the negative pressure source includes equipment that can generate negative pressure, such as a vacuum pump and a vacuum generator). During operation, the material in the turnover bucket 1 is placed into the elastic tube 5. The gas source inflates the downcomer 2 through the air inlet joint 20, and the gas enters the space between the elastic tube 5 and the downcomer 2. As the gas continuously increases, the elastic tube 5 gradually contracts, and the channel of the elastic tube 5 slowly becomes narrower. In this way, the falling speed of the material in the elastic tube 5 can be slowed down, thus avoiding damage to the material caused by a large drop; when it is necessary to block the material in the elastic tube 5 or accelerate the falling speed or restore the initial state of the elastic tube 5, the gas supply from the gas source is cut off, and the negative pressure source evacuates the air through the vacuum joint 21, so that the air between the elastic tube 5 and the downcomer 2 is discharged, and the channel of the elastic tube 5 gradually becomes larger.
[0018] By controlling the intake air volume of the gas, the contraction of the elastic tube 5 can be accurately controlled, thereby accurately controlling the feeding speed; at the same time, since the air pressure inside the downcomer 2 is consistent, the air pressure acting on the elastic tube 5 can make the inner wall surface of the elastic tube 5 smoother. Even if the inner diameter of the downcomer 2 becomes smaller and the feeding speed slows down, it can ensure that all particulate materials fall smoothly without blocking or jamming.
[0019] As described above, the particulate material is contained in the turnover bucket 1, so the turnover bucket 1 is included; in order to automatically connect the turnover bucket 1 to the downcomer 2, as Figure 2 shown, an airbag connection mechanism 7 is connected to the upper end of the downcomer 2. As Figure 3 shown, the airbag connection mechanism 7 includes an airbag 70, an airbag seat 71, an airbag lifting power source 74, a telescopic tube 72 (made of flexible material and can be telescoped up and down, such as a plastic film sleeve, a plastic corrugated pipe, a rubber tube, a silicone tube, etc.) and a telescopic tube connecting sleeve 73. Among them, the airbag 70 is connected to the airbag seat 71, the upper end of the telescopic tube 72 is connected to the airbag seat 71, the lower end of the telescopic tube 72 is connected to the telescopic tube connecting sleeve 73, and the telescopic tube connecting sleeve 73 is arranged at the upper port of the downcomer 2. After the turnover bucket 1 containing the material comes, the airbag lifting power source 74 drives the airbag seat 71 to move up and down, so that the airbag 70 sleeves on the discharge port 10 of the turnover bucket 1, and then the airbag 70 is inflated to wrap the discharge port 10 of the turnover bucket 1 to form a seal (to prevent the air in the space where the turnover bucket 1 is located from entering the lower elastic tube 5 and contaminating the material), so that the material in the turnover bucket 1 can be placed into the elastic tube 5.
[0020] Some particulate materials may have powder on their surfaces (such as drug granules), and powder may also be generated by the friction between particulate materials. These drug powders will fall on the inner walls of the telescopic tube 72, the telescopic tube connecting sleeve 73, and the elastic tube 5; when one kind of material is packaged and then another kind of material needs to be changed, this material will stick to the powder of the previous material, thus causing pollution to the material. To solve this problem, as Figure 2 shown, a straight plastic film 6 is connected to the airbag seat 71. As Figure 3 shown, this straight plastic film 6 is located inside the elastic tube 5, and the lower end of the straight plastic film 6 extends below the falling tube 2. During operation, the material in the turnover barrel 1 is placed into the straight plastic film 6, and the material then falls along the straight plastic film 6. When one kind of material is packaged and then another kind of material needs to be changed, only the straight plastic film 6 needs to be replaced, so that the material will not cause pollution to the telescopic tube 72, the telescopic tube connecting sleeve 73, and the elastic tube 5, and there will be no pollution between different materials.
[0021] To facilitate the connection between the airbag connection mechanism 7 and the falling tube 2, as Figure 3 shown, 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 an inclined surface. When placing the airbag connection mechanism 7, the lower section of the telescopic tube connecting sleeve 73 is placed into the falling tube 2, and the middle section 730 of the telescopic tube connecting sleeve 73 acts on the upper port of the falling tube 2. In this way, the airbag connection mechanism 7 is very conveniently connected to the falling tube 2, and a seal is formed between the inclined surface of the middle section 730 of the telescopic tube connecting sleeve 73 and the upper port of the falling tube 2.
[0022] As Figure 3 shown, the lower end of the elastic tube 5 is turned outwards and connected to the outside of the lower port of the falling tube 2, and the upper end of the elastic tube 5 is turned outwards and connected to the outside of the upper port of the falling 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 it convenient to connect the elastic tube 5 to the falling tube 2, but also due to the presence of an elastic material (i.e., the elastic tube 5) between the falling tube 2 and the telescopic tube connecting sleeve 73, the sealing performance between the falling tube 2 and the telescopic tube connecting sleeve 73 is stronger.
[0023] As Figure 2 shown, the feed pipe 3 is connected to the lower sleeve 31 through a valve 30, and the lower sleeve 31 is connected to the lower end of the falling tube 2 (the connection is detachable, which is convenient for installing and replacing the elastic tube 5 and arranging the straight plastic film 6). When the material falling is completed, the valve 30 is closed to prevent the air in the space where the turnover barrel 1 is located from entering the lower part through the pipeline and polluting the space where the blister packaging machine 4 is located.
[0024] As Figure 3 shown, a photoelectric sensor 8 is provided at the upper port of the falling tube 2. As 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 there is no material falling, it transmits a signal to the control center 9, and the control center 9 controls the alarm 90 to sound an alarm (sound alarm or / and light alarm) to inform the staff.
[0025] As described above, the turnover barrel 1 is installed on the walking trolley 12, and the walking trolley 12 can conveniently transport the turnover barrel 1 so that the discharge port of the turnover barrel 1 can reach the top of the drop pipe 2. A material control valve 11 is installed at the discharge port of the turnover barrel 1. When the turnover barrel 1 is in place, the material can be controlled to be lowered through the material control valve 11.
[0026] like Figure 2 As shown, the feed pipe 3 is located in the lower layer A, which is on the same layer as the blister packaging machine 4, and the turnover barrel 1 is located in the upper layer C, which is specially used for producing granular materials. In this way, the workshop for producing materials is separated from the workshop for packaging materials, and they do not affect or pollute 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 in the middle layer B (the middle layer B is used to install various pipelines as well as air sources and negative pressure sources).
[0027] Finally, it is worth mentioning that the lower layer A is the clean layer, and the upper layer C is the clean layer. The clean layer is a workshop that will not be polluted by the outside world.
