[0030] An embodiment of the present application provides a capsule powder filling device, which can realize the filling of powder into a capsule cap body. During the filling, the powder can be Chinese medicine powder, Mongolian medicine powder or Tibetan medicine powder, etc. The filling of Mongolian medicine powder is introduced below.
[0031] like Figure 1 As shown, the capsule powder filling device includes a base frame 100, a powder bin 300 and a slider 400, wherein the base frame 100 is a structure for installing and supporting other components, the powder bin 300 is filled with Mongolian medicine powder and is a container for holding Mongolian medicine powder, and the slider 400 is a component that carries the capsule cap.
[0032] like Figure 1 and Figure 4 As shown, the base frame 100 includes a bottom plate 110, a support plate 120 and a top plate 130. The support plate 120 is connected to the same side of the bottom plate 110 and the top plate 130, generally forming a "C"-shaped structure. The bottom plate 110 is provided with a horizontal guide rib 111 and a vertical mounting hole 112. The horizontal guide rib 111 extends along the length direction of the bottom plate 110. The vertical mounting hole 112 is provided with an elastic positioning shaft 200, and the elastic positioning shaft 200 can be extended and retracted in the vertical direction.
[0033] like Figure 1 As shown, the medicine powder bin 300 is arranged on the top plate 130, and a feeding pipe 310 is arranged at the bottom of the medicine powder bin 300, and a solenoid valve (not shown in the figure) is arranged on the feeding pipe 310. Mongolian medicine powder is contained in the medicine powder bin 300, and when the solenoid valve on the feeding pipe 310 is opened, the Mongolian medicine powder can fall under the action of gravity and fall out of the feeding pipe 310.
[0034] like Figure 2 As shown, a slide groove 410 is provided on the bottom surface of the slider 400 , and the slide groove 410 cooperates with the horizontal guide rib 111 , so that the entire slider 400 can move along the horizontal guide rib 111 , and the horizontal guide rib 111 can also position the slider 400 along the width direction of the bottom plate 110 .
[0035] like Figure 2 and Figure 3 As shown, a plurality of positioning holes 420 are provided on the bottom surface of the slider 400, and the plurality of positioning holes 420 are spaced apart along the length direction of the slide groove 410. A plurality of placement holes 430 are provided on the top surface of the slider 400. The number of the plurality of placement holes 430 is equal to the number of the plurality of positioning holes 420 and they are arranged one-to-one. A capsule cap body is coaxially placed in the placement hole 430. It can be understood that the placement hole 430 and the positioning hole 420 are arranged in groups.
[0036] When the slider 400 moves along the horizontal guide rib 111, the elastic positioning shaft 200 can extend into any positioning hole 420, and the placement hole 430 corresponding to the positioning hole 420 is coaxial with the drop tube 310. For example, when the elastic positioning shaft 200 extends into the first positioning hole 420, the first placement hole 430 is coaxial with the drop tube 310, so that the capsule cap body in the placement hole 430 is coaxial with the drop tube 310, thereby reducing the possibility of Mongolian medicine powder falling outside the capsule cap body.
[0037] When in use, the capsule cap to be filled is first coaxially placed into the placement hole 430 of the slider 400 to receive the Mongolian medicine powder. The slider 400 moves along the horizontal guide rib 111. When the elastic positioning shaft 200 is opposite to the first positioning hole 420 of the slider 400, the elastic positioning shaft 200 extends into the first positioning hole 420. At this time, the capsule cap in the placement hole 430 is coaxial with the drop tube 310. The solenoid valve is opened, and the Mongolian medicine powder falls into the capsule cap. After a certain period of time, the solenoid valve is closed (it can be manually closed by the filling personnel, or it can be automatically closed after being opened for a certain period of time), and the filling of the first capsule cap is realized. Continue to move the slider 400 and repeat the operation until the last capsule cap is filled.
[0038] Compared with the prior art, the capsule powder filling device can make the cap body and the drop tube 310 coaxial through the cooperation of the elastic positioning shaft 200 and the positioning hole 420, thereby reducing the possibility of the powder falling outside the cap body, reducing the waste of the powder and saving costs.
[0039] In some embodiments, Figure 4 As shown, the elastic positioning shaft 200 includes a spring 210 and a positioning shaft 220. The spring 210 is arranged in the vertical mounting hole 112. The positioning shaft 220 is slidably connected in the vertical mounting hole 112 and connected to the upper end of the spring 210. The upper end of the positioning shaft 220 forms a hemispherical shape. The bottom surface of the slider 400 presses the positioning shaft 220. When the positioning shaft 220 is opposite to the positioning hole 420, the positioning shaft 220 can extend into the positioning hole 420 under the elastic force of the spring 210 to achieve positioning. The upper end of the positioning shaft 220 is a hemispherical structure, which is easier to separate from the positioning hole 420, so as to facilitate the continued movement of the slider 400 after filling a capsule cap body.
[0040] In some embodiments, Figure 2 As shown, a guiding slope 411 is provided at one end of the slide groove 410, and the guiding slope 411 can facilitate the matching of the slide groove 410 with the horizontal guide rib 111, which is easy to operate.
[0041] In some embodiments, Figure 1As shown, the feeding tube 310 includes an outer tube 311 and an inner tube 312, the outer tube 311 is connected to the bottom of the powder bin 300, the inner tube 312 is slidably connected to the outer tube 311, and the electromagnetic valve is arranged on the inner tube 312. The inner tube 312 can be raised and lowered relative to the outer tube 311, so that the position of the bottom end of the feeding tube 310 can be changed. When the capsule cap body is coaxial with the feeding tube 310, the inner tube 312 descends and can extend into the upper end of the capsule cap body, so that the Mongolian medicine powder directly enters the capsule cap body from the inner tube 312, further reducing the possibility of the Mongolian medicine powder falling outside the capsule cap body.
[0042] In some embodiments, Figure 1 As shown, a mounting plate 140 is provided on the support plate 120, and an electric push rod 150 is provided on the mounting plate 140. The electric push rod 150 is vertically arranged, and the electric push rod 150 is connected to the inner tube 312 through a connecting plate 160. The lifting and lowering of the inner tube 312 is realized by the electric push rod 150, which is convenient and quick. In implementation, the electric push rod 150 can be controlled in linkage with the solenoid valve, that is, when the electric push rod 150 is extended, the solenoid valve is opened. When the solenoid valve is closed, the electric push rod 150 is retracted. Of course, these two components can also be manually controlled, which is not limited here.
[0043] In some embodiments, Figure 5 As shown, a motor 320 is provided on the powder bin 300, and the motor 320 is connected to a rotating shaft 330, and a scraper 340 is provided on the rotating shaft 330, and the scraper 340 abuts against the inner wall of the powder bin 300. When the motor 320 is started, the scraper 340 can scrape the inner wall of the powder bin 300 to prevent the Mongolian medicine powder from adhering to the inner wall of the powder bin 300.
[0044] In some embodiments, Figure 1 As shown, four legs 170 are provided below the bottom plate 110 , and each leg 170 is provided with an anti-skid rubber pad 180 . The anti-skid rubber pad 180 can increase the friction force, making the whole device less likely to shake, thereby ensuring a smooth filling process.
[0045] In some embodiments, the slider 400 is made of plastic. Plastic is light in weight. Compared with steel, the slider 400 made of plastic is lighter and more labor-saving to operate.
[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
