Description

Technical Field

[0001] This utility model relates to the field of food and pharmaceutical packaging machinery technology, and in particular to a feeding device for micro-sheets or soft capsules. Background Technology

[0002] Taking micro-flakes as an example, existing micro-flake feeding devices control the feeding of micro-flakes by opening and closing a pneumatic or manual butterfly valve. Opening the butterfly valve opens the feeding channel, allowing the micro-flakes to flow into the receiving container; closing the butterfly valve closes the feeding channel, causing the micro-flakes to remain at the top of the valve and unable to flow into the receiving container. While this technical solution can control the feeding of micro-flakes, it also has obvious drawbacks, namely, damage to the micro-flakes. When the butterfly valve is open, because the valve plate is upright and relatively thin, the micro-flakes will collide and be squeezed against the valve plate during the downward flow, damaging the micro-flakes. During the closing process, the gap between the valve plate and the valve wall gradually decreases, and the micro-flakes will become stuck between the valve plate and the valve wall due to the increasingly smaller gap during the downward flow. After the butterfly valve is completely closed, the micro-flakes stuck between the valve plate and the valve wall are crushed, resulting in significant waste and an inability to control the feeding speed of the micro-flakes. Utility Model Content

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0028] Figures 1 to 4An embodiment of the feeding device for microcapsules or soft capsules of this utility model is shown. The feeding device for microcapsules or soft capsules of this embodiment includes a feeding channel 1, a vibrating baffle 2 is provided in the feeding channel 1, and a feeding gap 4 is provided between the baffle 2 and the side wall of the feeding channel 1.

[0029] In this embodiment, the feeding device for micro-flakes or soft capsules has a simple structure. During feeding, the baffle 2 is stationary, and the material falls onto the baffle 2 and is bridged and blocked, thus stopping its downward flow. When discharge is required, the baffle 2 vibrates, causing the bridged material on the baffle 2 to collapse and flow outwards. Then, it flows downwards through the surrounding feeding gaps 4. This simple structure helps to avoid the problems of material colliding and being squeezed by the sharp valve plates, which exist in existing butterfly valves. The material is also less likely to get stuck in the feeding gaps 4 between the baffle 2 and the side wall of the feeding channel 1 and be crushed, thus greatly reducing material waste.

[0030] See details Figure 1 and Figure 2 Furthermore, in this embodiment, the baffle 2 is provided with an extension extending to the outside of the material discharge channel 1, and the extension is connected to a vibrator 3. When material needs to be discharged, the vibrator 3 is turned on, driving the baffle 2 to vibrate. The vibrator 3, located outside the material discharge channel 1, does not occupy the space of the material discharge channel 1, and the structure is simple and effective. Of course, in other embodiments, the vibrator 3 can also be a magnetic vibrator. The magnetic vibrator does not need to be connected to the baffle 2, and can still drive the baffle 2 to vibrate through magnetic force. In this case, the baffle 2 does not need to be provided with an extension.

[0031] In a preferred embodiment, the vibrator 3 is a pneumatic vibrator, which is connected to a gas source component (not shown in the figure, such as an air compressor) for providing compressed gas. The pressure of the compressed gas is adjustable. When the discharge speed is too fast or too slow, it can be adjusted by regulating the pressure of the compressed gas flowing into the pneumatic vibrator, which is very convenient and controllable.

[0032] In a preferred embodiment, the material discharge channel 1 includes an upper material discharge channel 11 and a lower material discharge channel 12. The upper end of the lower material discharge channel 12 is sleeved on the outer periphery of the lower end of the upper material discharge channel 11, which can provide a certain protective effect for the material. One end of the material stopper 2 is located inside the lower material discharge channel 12 and has a material discharge gap 4 between it and the side wall of the lower material discharge channel 12.

[0033] See details Figure 2 and Figure 4In this embodiment, the side wall of the lower material drop channel 12 is provided with an adjustment channel 13 for the material stop 2 to pass through. The thickness of the material stop 2 is a, and the height of the adjustment channel 13 is b. Then a < b. When the material stop 2 needs to move up and down, the adjustment channel 13 will not cause obstruction. The material stop 2 is connected to a height adjustment component 5. That is, the height of the material stop 2 is adjusted by the height adjustment component 5, thereby adjusting the height difference between the material stop 2 and the lower end outlet of the upper material drop channel 11 so as to adapt to different materials.

[0034] See details Figure 1 and Figure 2 In this embodiment, the upper material discharge channel 11 is provided with a first connecting part 14, and the lower material discharge channel 12 is provided with a second connecting part 15. The first connecting part 14 and the second connecting part 15 are connected by a locking member 6, thereby fixing the upper material discharge channel 11 and the lower material discharge channel 12 relatively. Preferably, the locking member 6 is a locking bolt, which has a simple structure, reliable locking, and convenient disassembly.

[0035] Furthermore, in this embodiment, the height adjustment component 5 includes an adjusting bolt 51, an adjusting nut 52, and a locking nut 53. The adjusting bolt 51 passes through the first connecting part 14 and the second connecting part 15. The adjusting nut 52 and the locking nut 53 are disposed on the adjusting bolt 51, and the stop member 2 is connected to the adjusting nut 52. When the height of the stop member 2 needs to be adjusted, first loosen the locking nut 53, then rotate the adjusting bolt 51. The locking nut 53 will move up and down relative to the adjusting bolt 51, and the stop member 2 will move up and down with the locking nut 53. Finally, tighten the locking nut 53 again to fix the height of the stop member 2. The structure is simple and the adjustment is convenient.

[0036] Furthermore, in this embodiment, a positioning groove 16 is provided at the upper end of the lower material drop channel 12, and the first connecting part 14 is disposed in the positioning groove 16. By providing the positioning groove 16, it is convenient to position the upper material drop channel 11 and the lower material drop channel 12 when they are docked, and at the same time, it helps to prevent the upper material drop channel 11 and the lower material drop channel 12 from rotating relative to each other.

[0037] Preferably, at least one end of the discharge channel 1 is provided with a connecting flange 17 to facilitate docking of the discharge channel 1 with other containers above and / or below. In this embodiment, both the upper end of the upper discharge channel 11 and the lower discharge channel 12 are provided with connecting flanges 17. Furthermore, a sealing groove can be provided on the end face of the connecting flange 17 for arranging a sealing ring to improve the sealing performance during docking.

[0038] In a preferred embodiment, the baffle 2 is a baffle plate, which has a simple structure, can bear a certain amount of material, and the amount of material remaining on the baffle plate after vibration is small. Of course, in other embodiments, the baffle 2 may also adopt other structures.

[0039] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
