Description

Technical Field

[0001] The invention relates to a packaging machine, in particular to a granular material feeding pipe and a granular material feeder. Background Art

[0002] Blister packaging machines are an automated packaging equipment mainly used for solid tablets (round tablets, oval tablets, square tablets, etc.) or capsules. The process flow is to arrange the blisters according to a certain pattern to form blisters, then add the materials to be packaged into the blisters, and then cover them with a layer of aluminum foil for heat sealing, and then print the batch number and punch them into the appropriate size. Conventional packaging filling methods generally include manual, disc brush, special feeder and other forms. Among them, special feeders have many forms, and the corresponding feeder is selected according to the different packaging materials required. The general feeder includes an organic base, a hopper and a feed pipe. The granular material in the hopper enters the feed pipe, and the feed pipe guides the material downward. However, the through hole of the general feed pipe is a straight hole (such as Figure 7 As shown in the figure, when this type of feed pipe enters the oval material, the upper and lower oval materials may both fall with their front faces facing in the same direction. In this way, the pointed ends of the upper and lower materials will be staggered and stuck together, causing the materials to be unable to fall normally, thereby causing the feed pipe to be blocked. Summary of the Invention

[0003] In view of the deficiencies in the prior art, the utility model innovatively provides a granular material feeding pipe and a granular material feeder that can prevent material blockage.

[0006] The feeding device includes a drop screen, which is located below the feeding pipe. The drop screen has a drop hole, and the drop hole of the drop screen is communicated with the spiral through hole of the feeding pipe.

[0007] The blanking screen is composed of several blanking plates spliced ​​together front and back. A row of blanking grooves is provided on one side of the blanking plate. The blanking groove of one blanking plate and the other side of the adjacent blanking plate form a row of blanking holes.

[0008] A lower fixing plate is installed on the machine base, lower fixing holes are distributed on the lower fixing plate, and the lower end of the feed pipe is inserted into the lower fixing hole of the lower fixing plate.

[0009] The lower end of the feed pipe is provided with a lower clamping position, and the lower clamping position is clamped on the lower fixed plate.

The feed pipe seat has multiple seat holes, and the feed pipe passes through the seat hole of the feed pipe seat. The lower part of the feed pipe seat has a clamping part with a diameter larger than the upper fixed hole, and the feed pipe has an upper clamping position. The clamping part of the feed pipe seat is clamped on the upper clamping position of the feed pipe, and the clamping part of the feed pipe seat is clamped on the bottom of the upper fixed plate.

[0019] like Figure 1 As shown, this particulate material feeder includes a hopper 1 and a feeding device 2. The hopper 1 feeds the feeding device 2, and the feeding device 2 adds the particulate material into the bubble cap plate. The feeding device 2 includes an organic base 8 and a feeding pipe 3. Generally, the through hole of the feeding pipe 3 is a straight hole, such as Figure 7 As shown, when the feed tube 3 enters the elliptical material, the upper and lower elliptical materials may both fall with their front faces facing the same direction. In this way, the pointed ends of the upper and lower materials will be staggered and stuck together, causing the materials to be unable to fall normally, thereby causing the feed tube 3 to be blocked. In order to solve this problem, the through hole of the feed tube 3 of the present invention is a spiral through hole 30, as shown in FIG. Figure 6 As shown, the spiral through hole 30 can make the pointed ends of two adjacent materials always press together, so that the material will not be misplaced or stuck, ensuring that the feed pipe 3 can always pass the material normally.

[0020] like Figure 2As shown, the feeding device 2 also includes a drop screen 4, which is located below the feed pipe 3. The drop screen 4 has a drop hole 40, which communicates with the spiral through hole 30 of the feed pipe 3. The drop hole 40 of the drop screen 4 is connected to the feed pipe 3. After the material enters the feed pipe 3, it can enter the drop screen 4 and then fall from the drop screen 4 into the blister. Of course, some types of feeders do not require a drop screen 4.

[0021] like Figure 2 As shown, the blanking screen 4 is composed of several blanking plates 41 spliced ​​together front and back, and a row of blanking grooves are provided on one side surface of the blanking plate 41. The blanking groove of one blanking plate 41 and the other side surface of the adjacent blanking plate 41 form a row of blanking holes 40. When multiple blanking plates 41 are spliced ​​together front and back, matrix blanking holes 40 are formed. The blanking screen 4 composed of this splicing is easier to manufacture and more convenient to assemble. It is also more convenient to adjust the matrix form to meet different feeding requirements.

[0022] In order to facilitate the fixing of the feed pipe 3, as Figure 5 As shown, a lower fixing plate 5 is mounted on the machine base 8, and lower fixing holes are distributed on the lower fixing plate 5. The lower end of the feed pipe 3 is inserted into the lower fixing hole of the lower fixing plate 5. In this way, the lower end of the feed pipe 3 is fixed on the lower fixing plate 5.

[0023] In order to be able to jam the feed pipe 3, as Figure 4 and Figure 5 As shown, the lower end of the feed pipe 3 has a lower clamping position 32, and the lower clamping position 32 is clamped on the lower fixed plate 5. After the lower end of the feed pipe 3 is fixed on the lower fixed plate 5, it can be restricted from moving downward.

[0024] The feed pipe 3 is only fixed at the lower end, which may be unstable. In order to stably fix the feed pipe 3, Figure 5 As shown, an upper fixing plate 6 is also installed on the machine base 8. Upper fixing holes are distributed on the upper fixing plate 6, and the feed pipe 3 passes through the upper fixing holes. By fixing the two ends of the upper fixing plate 6 and the lower fixing plate 5, the feed pipe 3 can be firmly fixed.

[0025] As mentioned above, the upper fixing plate 6 is provided with an upper fixing hole. If the upper fixing hole is opened too large, the feed pipe 3 will swing after passing through, affecting the connection with the material tray (the upper end of the feed pipe 3 must be inserted into the feed hole of the material tray). If the upper fixing hole is opened too small, it is not convenient for the feed pipe 3 to pass through. Because there are many feed pipes 3, it is difficult to align them one by one with the upper fixing hole and then insert them. In order to solve this problem, the utility model provides a feed pipe seat 7 in the upper fixing hole of the upper fixing plate 6. Figure 3 As shown, the feed pipe seat 7 has a plurality of seat holes, and multiple feed pipes 3 pass through these seat holes of the feed pipe seat 7 (such as Figure 3As shown, there are 6 feed pipes 3), forming a unit. Since the number of feed pipes 3 in this unit is small, it can be easily passed through the seat hole of the feed pipe seat 7, as shown in FIG. Figure 5 As shown, the lower portion of the feed pipe seat 7 has a clamping portion 71 with a diameter larger than the upper fixing hole, as shown in FIG. Figure 4 As shown, the feed tube 3 has an upper latch 31. When the upper fixing plate 6 is lowered, the lower portion of the latching portion 71 of the feed tube holder 7 is latched on the upper latch 31 of the feed tube 3, and the latching portion 71 of the feed tube holder 7 is latched on the lower portion of the upper fixing plate 6. In this way, all the feed tubes 3 can be conveniently fixed and accurately positioned.
