Description
Technical Field
The utility model belongs to the technical field of the capsule machine of filling, especially, machine is filled to capsule's feeding dustproof device.
Background
The capsule filling machine is a device for filling medicine powder into a hollow capsule shell and closing the cover. At present, a medicine powder feeding system of a capsule filling machine is arranged in a filling chamber in an open mode, and comprises a feeding funnel, a feeding pipeline, a powder bed cavity and the like. When the powder is transmitted, the material container filled with the powder is lifted to the upper end of the equipment through the lifter, the butterfly valve of the material container is opened to pour the powder into the feeding funnel, and the powder enters the powder bed cavity through the feeding pipeline after entering the feeding funnel. At the moment, certain pressure is applied to the medicinal powder at the lower part by the medicinal powder falling into the feeding funnel, so that the medicinal powder can leak through a mechanical interface between the feeding funnel, the feeding pipeline and the powder bed cavity to generate dust, particularly fine powder with smaller particles, the dust is more serious, the dust causes medicinal powder particles to scatter to other stations of equipment, subsequent cleaning work is more complicated, and various new medicines with high activity, radioactivity and unknown toxicity are developed in a large amount at present, the medicinal powder has toxicity, the cleaning work needs to be seriously done, and the risk of cleaning time and toxicity leakage is further increased.
SUMMERY OF THE UTILITY MODEL
In order to overcome the defects of the prior art, the utility model provides a simple structure prevents that the raise dust from flying, and effective little powder range that wafts improves the feeding dust prevention device of the capsule filling machine of clean efficiency.
In order to realize the purpose, the utility model discloses a technical scheme is: the dust cover comprises a dust cover body sleeved outside a powder feeding system, wherein two ends of the dust cover body are respectively in an open shape, a first sealing element and a second sealing element are respectively arranged at two ends of the dust cover body, the first sealing element is arranged on the periphery of a feeding end of a feeding hopper in a sealing mode, and the second sealing element is arranged on the outer wall of a powder bed cavity in a sealing mode.
Adopt above-mentioned scheme, establish a dust cover at powder charge-in system overcoat, prevent that the both ends of cover body from all being uncovered setting, make things convenient for its cover to establish, and the one end of dust cover sets up first sealing member in the periphery of feed hopper feed end, prevent that the dust from passing through by upper portion (it is peripheral that the feed hopper feed end here needs to notice, its scope is not less than feed hopper's the biggest external diameter), consequently can begin whole cover with feed hopper by the feed end and establish in the dust cover, and the other end of dust cover is provided with the second sealing member, the second sealing member cover is established at powder bed chamber outer wall, thereby can form sealedly with powder bed chamber outer wall, prevent that the dust from passing through. In conclusion, the flying space of the dust is limited between the feeding hopper and the powder bed cavity, and the dust cannot fly to other stations of the equipment through the dust cover, so that the dust flying phenomenon is avoided, and the follow-up cleaning time is greatly reduced.
As the utility model discloses a further setting, first sealing member includes that two are the elasticity supporting piece of cyclic annular setting, and two elasticity supporting pieces form the stack and compress tightly the periphery of fixing at the feed hopper feed end through compressing tightly, the one end seal clamp of dust cover body is established in the intermediate layer of two elasticity supporting pieces.
By adopting the scheme, the two elastic clamping pieces can form elastic pressing force under the action of the pressing piece, so that one end of the dust cover body can be clamped in the interlayer in a sealing manner, the two elastic clamping pieces are pressed and fixed at the periphery of the feeding end of the feeding funnel through the pressing piece, the first sealing piece can be prevented from falling off, the stable and dustproof effect is achieved, the structure is simple, the installation is convenient, and the replacement is easy.
As a further arrangement of the utility model, the second sealing element is an elastic tightening belt, and the other end of the dust cover body is tightened on the outer wall of the powder bed cavity through the elastic tightening belt.
By adopting the scheme, the other end of the dust cover body is tightly tied on the outer wall of the powder bed cavity through the elastic tying belt on the second sealing element, sealing can be effectively formed, the structure is simple, and the dismounting is convenient.
As a further arrangement of the utility model, the outer wall of the powder bed cavity is provided with an annular groove, and the elastic binding belt is elastically bound in the annular groove.
Adopt above-mentioned scheme, because the spare part between dust chamber outer wall and feed hopper is comparatively complicated, be unfavorable for elasticity to tighten the area and prick tightly to seal, the outer wall in dust chamber is relatively more even, can form sealedly with elasticity is pricked the area. Therefore, the annular groove is formed in the outer wall of the powder bed cavity, so that the elastic tightening belt is elastically tightened in the annular groove, the elastic tightening belt is prevented from sliding to other positions, and the sealing stability is improved.
The present invention will be further described with reference to the accompanying drawings.

Detailed Description
The utility model discloses a concrete embodiment is shown in fig. 1-3, a feeding raise dust prevention device of capsule filling machine, establish dust cover body 1 outside powder feed system including the cover, dust cover body 1 adopts transparent material's film to make, dust cover body 1's both ends are uncovered form respectively and are provided with first sealing member 2 and second sealing member 3 respectively at both ends, first sealing member 2 is sealed to be set up in the periphery of 4 feed ends of feed hopper, the outer wall at powder bed chamber 5 is established to 3 seal covers of second sealing member.
In this embodiment, first sealing member 2 includes that two are the elasticity supporting piece 21 of cyclic annular setting, and feed hopper 4's feed end sets up in the up end 6 of capsule filling machine, and two elasticity supporting pieces 21 form the stack and compress tightly the periphery of fixing at feed hopper 4 feed end through compressing tightly 7, compressing tightly 7 is gland nut, and capsule filling machine's up end 6 is provided with the screw that supplies gland nut threaded connection, is provided with the through-hole that supplies gland nut to wear to establish on two elasticity supporting pieces 21, and gland nut passes behind the through-hole with screw threaded connection, conveniently carries out the dismouting to first sealing member 2 to press from both sides the tight up end 6 at capsule filling machine with two elasticity supporting pieces 21, the one end 1a sealing clamp of dust cover body is established in the double-layered in situ of two elasticity supporting pieces 21.
