Abstract
Description
Technical Field
[0001] This utility model relates to the field of aseptic filling technology, and in particular to an anti-drip device for aseptic filling heads. Background Technology
[0002] In industries with stringent hygiene and precision requirements, such as food and pharmaceuticals, aseptic filling technology is widely used for the packaging of beverages, pharmaceutical solutions, and biological agents. During the filling process, the filling head, as a core component, directly impacts product quality and production efficiency.
[0003] In actual operation, the assembly line transports container bottles, then the electric push rod presses down to connect the filling head with the empty bottle, and the valve of the filling head automatically opens to output liquid into the container bottle for filling. After filling is completed, the valve closes, the electric push rod lifts the filling head, and the assembly line continues to transport the next set of container bottles for filling.
[0004] However, based on the existing filling technology, the filling head often faces the problem of dripping after completing the filling action: due to surface tension, liquid tends to remain on the inner wall or outlet of the filling head, forming droplets that slowly drip down, contaminating the outer wall of the filled container or the equipment table, leading to the risk of cross-contamination; therefore, there is an urgent need for a structurally optimized and highly reliable aseptic filling head anti-drip device to solve the pain points of the existing technology and meet the precise filling requirements under high hygiene standards. Utility Model Content
[0005] To solve the above-mentioned technical problems, this utility model provides an anti-drip device for aseptic filling heads.
[0006] This utility model is achieved using the following technical solution: an anti-drip device for an aseptic filling head, comprising a filling head body for filling empty bottles, and an anti-drip component fitted onto the outside of the filling head body. The anti-drip component includes a connecting sleeve fitted onto the outside of the middle part of the filling head body. A movable sleeve is provided at the bottom of the connecting sleeve, and the connecting sleeve and the movable sleeve are connected by a corrugated sleeve. Two sets of protective covers are symmetrically installed at the bottom of the movable sleeve. After the two sets of protective covers are fitted together, they seal the bottom of the movable sleeve. Openings are provided at the bottom of the two sets of protective covers. Multiple sets of fixing blocks are fixedly provided on the outside of both the connecting sleeve and the movable sleeve. The fixing blocks on the outside of the connecting sleeve and the fixing blocks on the outside of the movable sleeve correspond one-to-one. A guide pin is fixedly connected to the upper end of the fixing block on the outside of the movable sleeve, and the guide pin slides through and inserts into the fixing block on the outside of the connecting sleeve.
[0007] As a further improvement to the above solution, a threaded sleeve is provided on the outer side of the filling head body near the middle part. The surface of the threaded sleeve is provided with a bolt groove. A bolt is threaded into the inner wall of the bolt groove. The bolt fixes the threaded sleeve to the outside of the filling head body, and the bolt does not penetrate the outside of the filling head body.
[0008] As a further improvement to the above solution, the connecting sleeve and the threaded sleeve are connected by threads.
[0009] As a further improvement to the above solution, the protective cover is rotatably connected to the bottom of the movable sleeve via a rotating pin, and the mating surfaces of both sets of protective covers are provided with magnetic attracting plates that attract each other magnetically.
[0010] As a further improvement to the above solution, after the two sets of protective covers are fitted together, the two sets of openings at the bottom form a "frustum" structure.
[0011] As a further improvement to the above solution, a limiting block is fixedly connected to the upper end of the guide pin, and the limiting block is engaged with the fixing block on the outside of the connecting sleeve. A spring is sleeved on the part of the guide pin located between the upper and lower fixing blocks.
[0012] As a further improvement to the above solution, the upper and lower ends of the spring are respectively fixedly connected to the upper and lower sets of fixing blocks, and the spring is in a spring-stretched state when it is at rest.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] This utility model is based on the existing filling head body design and a drip-proof component is installed at its bottom. During the filling and descent process, the protective cover in the drip-proof component, together with the "frustum-shaped" opening, abuts against the upper end of the empty cup and then automatically opens. After the filling is completed, it automatically closes under the setting of the magnetic suction structure, thus completing the drip-proof design of the aseptic filling head.
[0015] Based on this, the present invention also features a retractable corrugated sleeve structure, which allows the filling head to be close to the empty cup during the filling process, thus avoiding splashing of the filling liquid due to large differences in filling height, which could contaminate the outer wall of the container or the equipment table and reduce the risk of cross-contamination.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0027] Please combine Figure 1-5The aseptic filling head anti-drip device includes a filling head body 1 for filling empty bottles, and an anti-drip component fitted on the outside of the filling head body 1. The anti-drip component includes a connecting sleeve 2 fitted on the outside of the middle part of the filling head body 1. A movable sleeve 3 is provided at the bottom of the connecting sleeve 2, and the connecting sleeve 2 and the movable sleeve 3 are connected by a corrugated sleeve 4. Two sets of protective covers 5 are symmetrically installed at the bottom of the movable sleeve 3. After the two sets of protective covers 5 are fitted together, they seal the bottom of the movable sleeve 3. An opening 6 is provided at the bottom of the two sets of protective covers 5. Multiple sets of fixing blocks 7 are fixedly provided on the outside of both the connecting sleeve 2 and the movable sleeve 3. The fixing blocks 7 on the outside of the connecting sleeve 2 and the fixing blocks 7 on the outside of the movable sleeve 3 correspond one-to-one. A guide pin 8 is fixedly connected to the upper end of the fixing block 7 on the outside of the movable sleeve 3, and the guide pin 8 slides through and is inserted into the fixing block 7 on the outside of the connecting sleeve 2.
[0028] The filling head body 1 has a threaded sleeve 101 fitted on the outer side near the middle. The threaded sleeve 101 has a bolt groove 102 on its surface, and a bolt is threaded into the inner wall of the bolt groove 102. The bolt fixes the threaded sleeve 101 to the outside of the filling head body 1. A connecting sleeve 2 is threadedly connected to the threaded sleeve 101. During the installation of the anti-drip assembly, the operator first movably fits the threaded sleeve 101 onto the outer side of the filling head body 1 near the middle. Then, the bolt fixes the threaded sleeve 101 to the outside of the filling head body 1. The bolt groove 102 on the outside of the threaded sleeve 101 does not protrude, thus not affecting the subsequent installation between the connecting sleeve 2 and the threaded sleeve 101. Furthermore, the bolt does not penetrate the outer side of the filling head body 1, thus preventing damage to the structure of the filling head body 1 itself.
[0029] The protective cover 5 is rotatably connected to the bottom of the movable sleeve 3 via a rotating pin 501. Both sets of protective covers 5 have magnetically attracted plates 502 on their mating surfaces. After the two sets of protective covers 5 are fitted together, the two openings 6 at the bottom form a frustum-shaped structure. Furthermore, the filling head body 1 has a flange at its upper end, which is bolted to the power end of the electric push rod. During filling, as the two sets of protective covers 5 descend along with the filling head body 1 under the drive of the electric push rod, the openings 6 of the frustum-shaped structure at the bottom of the two sets of protective covers 5 automatically open after touching the upper end of the empty bottle. The rotating pin 501 causes the protective covers 5 to rotate. After filling, the entire structure is lifted, at which point the openings 6 are no longer in contact with the empty bottle. Under the magnetic attraction of the magnetic attracted plates 502 on the opposite surfaces, the opposing protective covers 5 magnetically attract each other, automatically fitting together.
[0030] The guide pin 8 has a fixed upper end connected to a limiting block 801, which engages with the fixing block 7 on the outside of the connecting sleeve 2. A spring 802 is fitted on the portion of the guide pin 8 between the upper and lower fixing blocks 7. The upper and lower ends of the spring 802 are fixedly connected to the upper and lower fixing blocks 7, respectively, and the spring 802 is in a spring-extended state when stationary. Based on the above, during the filling process, as the electric push rod presses down on the filling head body 1, the protective cover 5 abuts against the upper end of the empty bottle. The electric push rod continues to press down, and at this time, the corrugated sleeve 4 between the connecting sleeve 2 and the movable sleeve 3 folds and retracts (the corrugated sleeve 4 is similar to a corrugated pipe and can be designed to retract and fold, which will not be elaborated further here). At the same time, the guide pin 8 at the upper end of the fixing block 7 on the outside of the movable sleeve 3 is inserted into the fixing block 7 on the outside of the connecting sleeve 2 to achieve vertical guidance and prevent deviation. Meanwhile, the fixing block 7 on the outside of the connecting sleeve 2 squeezes and compresses the spring 802 at the bottom. After filling is completed, as the electric push rod drives the filling head body 1 to rise and release contact with the empty bottle, the corrugated sleeve 4 will unfold and reset again under the elastic restoring force of the spring 802.
[0031] Implementation: 1. Based on the above structural setup, when the empty bottles on the production line are docked at the bottom of the filling head body 1, the two sets of protective covers 5 descend along with the filling head body 1 under the drive of the electric push rod. The inclined surfaces of the inner walls of the "frustum-shaped" openings 6 at the bottom of the two sets of protective covers 5 touch the upper end of the empty bottle and rotate in conjunction with the rotating pin 501, thereby automatically opening the two sets of protective covers 5. As the electric push rod continues to press down, the corrugated sleeve 4 between the connecting sleeve 2 and the movable sleeve 3 folds and retracts, and the filling head body continues to descend and dock with the empty bottle. Once the upper part of the bottle reaches the preset position, the valve on the outside of the filling head body 1 opens to perform automated filling. After filling is completed, the electric push rod drives the filling head body 1 to rise and release contact with the empty bottle. At this time, the magnetic suction plates 502 on opposite sides magnetically attract each other and automatically adhere to the protective covers 5 under magnetic attraction, thereby sealing the bottom of the filling head body 1. During this process, the empty bottle after filling has not yet rotated away, but the protective covers 5 can seal the bottom of the filling head body 1 to prevent dripping and avoid polluting the surrounding environment.
[0032] Example 2: Further supplement, during the filling process, after the two sets of protective covers 5 are opened, the electric push rod continues to press down. At this time, the corrugated sleeve 4 between the connecting sleeve 2 and the movable sleeve 3 folds and retracts. At the same time, the guide pin 8 at the upper end of the fixing block 7 on the outer side of the movable sleeve 3 is inserted into the fixing block 7 on the outer side of the connecting sleeve 2 to achieve vertical guidance and avoid deviation. Meanwhile, the fixing block 7 on the outer side of the connecting sleeve 2 squeezes and compresses the spring 802 at the bottom. During this process, the filling head body 1 will be closer to the upper end of the empty bottle. In this way, the drop difference between the two is smaller during the filling process, reducing the possibility of liquid splashing outside and causing contamination due to the large drop difference during the filling process, thus indirectly achieving the effect of preventing dripping.
[0033] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
