Description

Technical Field

[0001] The utility model relates to the field of capsule cup filling and sealing, in particular to a vacuuming and nitrogen filling mechanism. Background Art

[0002] Capsule-cup products, such as coffee capsules, probiotic capsules, and milk powder capsules, are increasingly popular among consumers due to their convenience and stability. Coffee and milk powder are both easily oxidized products, and most probiotic strains are anaerobic. Therefore, filling these capsule-cup formats requires a low or even no residual oxygen environment, but current filling systems cannot meet this requirement. Utility Model Content

The filling protection chamber is wrapped around the outside of the capsule cup conveying mechanism. The positive pressure nitrogen environment formed by the filling protection chamber wrapped around the outside of the capsule cup conveying mechanism can replace the air in the empty capsule cup and provide a positive pressure nitrogen environment for each workstation that can be embedded in the filling protection chamber. The vacuum nitrogen filling mechanism vacuums the capsule cup filled with material, directly sucks away the air, and replenishes nitrogen into the capsule cup, thereby achieving an almost oxygen-free environment in the capsule cup.

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] A vacuum nitrogen filling mechanism includes a nitrogen filling vacuum cover 41, a nitrogen filling vacuum lifting mechanism 42, a capsule cup conveying mechanism 43, and a filling protection chamber 44. The nitrogen filling vacuum cover 41 is connected to the nitrogen filling vacuum lifting mechanism 42 and is arranged on the inner and outer sides corresponding to the upper and lower sides of the capsule cup conveying mechanism 43. The filling protection chamber 44 is wrapped around the outside of the capsule cup conveying mechanism 43. A nitrogen filling filter is provided inside the nitrogen filling vacuum cover 41. A trachea joint 411 is provided on one side of the nitrogen filling vacuum cover 41. The capsule cup conveying mechanism 43 includes a nitrogen filling transmission drive 431 and a nitrogen filling transmission placement block 432. The nitrogen filling transmission placement block 432 is sequentially connected to the nitrogen filling transmission drive 431 in an array. The nitrogen filling transmission drive 431 can be a belt drive or a chain drive, etc., which can drive the nitrogen filling transmission placement block 432 to rotate tightly in a cycle. The nitrogen filling transmission placement block 432 is provided with a capsule Cup placement hole, the capsule cup conveying mechanism 43 is also provided with an on-off valve, a vacuum pump, a nitrogen filling valve, and a nitrogen filling device. One side of the on-off valve is connected to the vacuum pump, and the other side is connected to the trachea joint 411. One side of the nitrogen filling valve is connected to the nitrogen filling interface of the nitrogen filling device, and the other side is connected to the trachea joint 411. The nitrogen filling device is also provided with an inflation hole for filling nitrogen into the capsule cup conveying mechanism 43. A plurality of through holes are provided on the upper part of the filling protection chamber 44. The nitrogen filling vacuum lifting mechanism 42 is a lifting cylinder. A movement gap margin is left between the filling protection chamber 44 and the nitrogen filling transmission placement block 432. The movement gap margin is 1 mm. Of course, a reasonable movement gap margin can also be formulated according to actual work requirements to meet the requirements of not affecting the movement of the nitrogen filling transmission placement block 432, and ensuring that the nitrogen continuously filled into the inflation hole of the nitrogen filling device expands in the filling protection chamber 44 without leaking too much.

[0026] Within the relatively sealed environment created by the capsule cup conveying mechanism 43 in the filling protection chamber 44, there are also some supporting equipment such as a nitrogen pressure tester, a nitrogen flow detection switch, a nitrogen concentration detector, a vacuum pressure tester, and tracheal fittings, which are not listed in this solution. The staff can determine the required equipment according to the actual situation during implementation. When the nitrogen content in the entire filling protection chamber 44 is insufficient, the nitrogen filling holes of the nitrogen filling equipment are continuously filled with nitrogen. When the nitrogen filling transmission placement block 432 drives the capsule cup to the position of the nitrogen filling vacuum cover 41, the nitrogen filling vacuum lifting mechanism 42 on both sides begins to work and pushes the nitrogen filling vacuum cover 41. The nitrogen filling vacuum cover 41 presses up and down against the nitrogen filling transmission placement block 432 to form a closed chamber environment. The on-off valve activates the vacuum pump to evacuate the closed chamber. Because the vacuum cover is equipped with a nitrogen filling filter, air is ventilated but powder is not, achieving the purpose of only extracting air and not absorbing materials. When the vacuum pressure reaches the set value, the vacuuming stops. The nitrogen filling valve is activated to further replenish nitrogen into the closed chamber. This leaves the capsule cup containing the material virtually free of air. After vacuuming and nitrogen filling, the internal and external nitrogen filling vacuum lift mechanism 42 returns to its original position, maintaining the positive nitrogen pressure in the capsule cup. The nitrogen filling transmission drive 431 drives the nitrogen filling transmission placement block 432 of the capsule cup containing the material to the next sealing station, completing the subsequent sealing of the capsule cup. This results in a nearly oxygen-free, qualified capsule product.
