Abstract
Description
Technical Field
[0001] The utility model relates to a powder blocking structure of a capsule filling machine. Background Art
[0002] A capsule filling machine is used to pour powder into capsules. To improve efficiency, usually more than one row of capsules can be filled at a time. When there are multiple rows of die holes to be filled, for example, a large capsule filling machine with four rows of die holes, problems such as excessive powder leakage on the table, poor filling measurement, and low finished product qualification rate often occur. The reasons are that the powder blocking plate of the large capsule filling machine leaks powder seriously, the metering disk surface is too large, there are many filling rods in the powder storage chamber, the fluidity of the material is poor, and the filling speed requirement is too fast, etc. Content of the Utility Model
[0003] Based on the above deficiencies, the utility model provides a powder blocking structure of a capsule filling machine, which is improved from multiple aspects.
[0004] The technical solution of the utility model is as follows:
[0005] A powder blocking structure of a capsule filling machine includes a capsule filling machine body. A metering disk fixed to a rotating frame is provided on the capsule filling machine body. A powder storage ring is fixed on the metering disk. The powder blocking plate is fixed to the frame. A powder inlet is provided at the center of the powder blocking plate. The metering disk, the powder storage ring, and the powder blocking plate form a container for holding powder. The powder storage ring can rotate relative to the powder blocking plate. The powder blocking block is fixed to the powder blocking plate and can scrape off the excess powder on the metering disk;
[0006] Preferably, a conical disk is fixed at the center of the metering disk, and the powder transported from the powder inlet to the container can spread to the periphery of the conical disk.
[0007] Preferably, a plurality of stirring blades are fixed to the outer edge of the conical disk. The stirring blades are close to the powder blocking block and do not touch the powder blocking block.
[0008] Preferably, a feed cylinder is fixed to the powder inlet. The inlet end of the feed cylinder communicates with the powder inlet, and the outlet end of the feed cylinder deviates from the center of the powder inlet.
[0009] Preferably, a blanking hopper is fixed to the outlet end of the feed cylinder, and the blanking hopper is located above the stirring blades.
[0010] Preferably, the blanking hopper is eccentrically arranged relative to the outlet end of the feed cylinder, and the large space of the blanking hopper can accommodate powder with a uniform thickness.
[0011] Preferably, the blanking hopper is a quadrilateral structure with rounded corners and one side being an arc edge.
[0012] Preferably, a plurality of scraping blades are fixed to the inner ring of the powder storage ring. The scraping blades can stir the powder in the container and also scrape off part of the powder outside the powder blocking block.
[0013] Preferably, both ends of the powder baffle are rounded, and there is a space between the outer side of the middle part of the powder baffle and the inner side of the powder storage ring.
[0014] Preferably, the circular ring plane where the metering holes of the metering disc are located is lower than other planes of the metering disc.
[0015] Compared with the prior art, the utility model has the following advantages:
[0016] It is not easy to cause unilateral stacking of the powder, and can effectively guide the powder into the outer metering die holes, improving the metering error of large filling equipment.
[0017] The utility model has the beneficial effects of simple structure, low cost, reducing powder accumulation and improving metering accuracy. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] Figure 2 is Figure 1 a partial side view of.
[0020] Figure 3 It is a schematic bottom view structure diagram of the utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0021] The present utility model will be further described below in conjunction with the drawings:
[0022] As Figures 1 - 3 shown, an embodiment: a powder baffle structure of a capsule filling machine, including a capsule filling machine body, the capsule filling machine body is provided with a metering disc 4 fixed to a rotating frame, a powder storage ring 2 is fixed on the metering disc 4, a baffle plate 1 is fixed to the frame, a powder inlet 6 is provided in the center of the baffle plate 1, the metering disc 4, the powder storage ring 2 and the baffle plate 1 form a container for storing powder, the powder storage ring 2 can rotate relative to the baffle plate 1, and a powder baffle 3 is fixed to the baffle plate 1 to scrape off the excess powder on the metering disc 4;
[0023] The metering disc of the present utility model is provided with multiple rows of metering holes, the multiple rows of metering holes correspond to multiple rows of pin holes, the powder can fall into the metering holes and can be pressed by the inserting pins, and this part is the prior art.
[0024] A conical disc 5 is fixed in the center of the metering disc 4, and the powder conveyed from the powder inlet 6 into the container can diffuse towards the periphery of the conical disc 5.
[0025] The present utility model adopts the conical disc 5 to diffuse the powder accumulated in the center towards the periphery, and can push the powder towards multiple rows of metering holes, that is, diffuse towards the direction of multiple rows of metering holes.
[0026] Furthermore, a plurality of stirring blades 51 are fixed to the outer edge of the conical disk 5. The stirring blades 51 are close to the powder blocking block 3 and do not touch the powder blocking block 3. A relatively large centrifugal force can be generated by the stirring blades 51, and this centrifugal force can further push the powder towards the multi-row metering holes.
[0027] Furthermore, a feeding cylinder 62 is fixed to the powder inlet 6. The inlet end of the feeding cylinder 62 communicates with the powder inlet 6, and the outlet end of the feeding cylinder 62 deviates from the center of the powder inlet 6. Directly sending the powder outside the center of the metering disk 4 is beneficial to preventing the powder from accumulating at the center.
[0028] Furthermore, a blanking hopper 61 is fixed to the outlet end of the feeding cylinder 62. The blanking hopper 61 is located above the stirring blades 51. The blanking hopper 61 has a certain accommodation space, and this accommodation space also has the effect of smoothing the powder accumulation.
[0029] Preferably, the blanking hopper 61 is eccentrically arranged relative to the outlet end of the feeding cylinder 62. The large space 63 of the blanking hopper 61 can accommodate the powder with a uniform thickness. It should be noted that in the structure of the present utility model Figure 1 when the metering disk 4 rotates counterclockwise, the effect is better, and the smoothing effect of the large space 63 is better.
[0030] Preferably, the blanking hopper 61 has a rounded corner and is a quadrilateral structure with one side being an arc edge.
[0031] In order to enable the multi-row metering holes to have a uniform filling amount, as Figure 3 shown, a plurality of scraping blades 21 are fixed to the inner ring of the powder storage ring 2. The scraping blades 21 can stir the powder in the container and can also scrape off part of the powder on the outer ring of the powder blocking block 3.
[0032] Preferably, both ends of the powder blocking block 3 are rounded, and a space 22 is left between the outer side of the middle part of the powder blocking block 3 and the inner side of the powder storage ring 2. This space 22 can store a certain amount of powder, which is very beneficial to improving the uniform filling of the powder in the holes in the middle part of the powder blocking block 3.
[0033] The circular ring plane where the metering holes of the metering disk 4 are located is lower than other planes of the metering disk 4. This stepped structure is beneficial to the concentration of the powder towards the circular ring plane where the metering holes are located, thereby improving the metering accuracy.
