Description

Technical Field

[0001] This utility model relates to the field of aerosol production technology, specifically a fully automated aerosol filling line with a guiding structure. Background Technology

[0002] Aerosol products (such as insecticides, air fresheners, spray paints, personal care products, and medical sprays) are widely used in modern industry and daily life due to their advantages such as ease of use, precise dosage, and good sealing. The core production process is aerosol filling, which typically includes the following key steps: empty can cleaning and drying, precise filling of contents (liquid or powder formulations), filling with propellant (liquefied or compressed gas), and finally, sealing the valve for airtightness.

[0003] When filling propellant (liquefied gas or compressed gas) into the tank, the tank may be offset, tilted or rotated due to slight dimensional tolerances or deformation of the tank itself, or due to vibration or collision during the transmission process. This can result in gaps in the connection between the tank opening and the injection mechanism, causing liquid or gaseous propellant to leak out, polluting equipment and the environment, wasting raw materials, and posing safety hazards. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, such as the inability to accurately align the can opening with the actuator, which causes leakage of liquid or gaseous propellants, this utility model proposes a fully automatic aerosol filling line with a guiding structure.

[0005] This utility model provides a fully automatic aerosol filling line with a guiding structure, including a machine body and a pushing mechanism, a conveying mechanism, a guiding and positioning mechanism and a filling mechanism disposed on the machine body. The conveying mechanism is disposed adjacent to the guiding and positioning mechanism, the pushing mechanism is disposed on one side of the conveying mechanism, and the filling mechanism is disposed above the guiding and positioning mechanism.

[0006] The guiding and positioning mechanism includes a positioning station, a fixed plate, a compression spring, a base, and a return spring. A guide groove is provided on the positioning station, and the base is installed in the guide groove. One end of the return spring is fixedly connected to the outside of the base, and the other end of the return spring is fixedly connected to the inner wall of the guide groove. One end of the compression spring is embedded in the upper end of the base, and the other end of the compression spring is fixedly connected to the fixed plate.

[0007] In some embodiments, the pushing mechanism includes a pushing cylinder and a pushing plate, the pushing cylinder being fixedly connected to one side of the machine body, and the pushing plate being fixedly connected to the output end of the pushing cylinder; a plurality of first positioning notches are provided on the side of the pushing plate near the conveying mechanism.

[0008] In some embodiments, a barrier is integrally formed on the other side of the machine body, and the barrier has a second positioning notch adapted to the first positioning notch. The first positioning notch and the second positioning notch form a spray bottle positioning groove; the filling mechanism is fixedly connected to the upper end of the barrier.

[0009] In some of these embodiments, the first positioning notch is equipped with an electromagnet.

[0010] In some embodiments, a stepper motor is mounted on one end of the push plate, and a baffle is hinged to one end of the push plate, with the output shaft of the stepper motor and the baffle keyed together.

[0011] In some embodiments, the filling mechanism includes a filling cylinder, a mounting plate, and a plurality of filling heads. The filling cylinder is fixedly mounted on the other end of the machine body, and one end of the mounting plate is fixedly connected to the output end of the filling cylinder. The filling heads are fixedly connected to the other end of the mounting plate.

[0012] In some embodiments, the upper surface of the fixing plate is a raised arc-shaped surface, which is lower than the upper surface of the positioning station, and the edge of the raised arc-shaped surface is provided with a groove that fits the bottom of the spray bottle.

[0013] In some embodiments, the lower end of the fixing plate is integrally formed with a plurality of guide posts, the upper end of the base is provided with a guide groove adapted to the guide posts, the compression spring is disposed in the guide groove, and the other end of the compression spring is fixedly connected to the guide posts.

[0014] In some embodiments, the bottom of the guide groove is provided with a limiting groove, the lower end of the base is integrally formed with a limiting plate, the bottom surface of the limiting plate is equipped with a ball, and the limiting plate and the ball are disposed in the limiting groove.

[0015] In some embodiments, the conveying mechanism is a belt conveyor.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The spray bottle from the conveying mechanism is pushed to the guiding and positioning mechanism by the pushing mechanism. The guiding and positioning mechanism guides and positions the spray bottle as it enters the positioning station. When it enters the positioning station, the spray bottle falls onto the upper part of the fixed plate. When the filling mechanism fills the spray bottle with liquid, the compression spring and the return spring play a role in initial buffering and deformation around the bottle, so that the spray bottle adjusts itself to the appropriate position under the force of the filling mechanism, ensuring that the liquid filling process does not deviate and avoiding leakage of liquid or gaseous propellant.

[0018] In addition, the upper end of the fixing plate has an arc-shaped surface and a spray bottle slot designed specifically for spray bottles. The arc-shaped surface can fit the bottom of the spray bottle, while the spray bottle slot can wrap around the bottom edge of the spray bottle, making the spray bottle more stable on the fixing plate. As the filling head body moves down into the spray bottle, the spray bottle above the fixing plate can more easily adjust itself to the appropriate position with the cooperation of the compression spring, the return spring and the lower ball bearing until the spray bottle is in a vertical position. After the injection is completed, the fixing plate will return to the middle of the guide channel due to the action of the return spring, further preventing the leakage of liquid or gaseous propellant.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0027] See Figures 1 to 3This application discloses a fully automatic aerosol filling line with a guiding structure, including a machine body 1 and a pushing mechanism 2, a conveying mechanism 3, a guiding and positioning mechanism 4 and a filling mechanism 5 disposed on the machine body 1. The conveying mechanism 3 is disposed adjacent to the guiding and positioning mechanism 4, the pushing mechanism 2 is disposed on one side of the conveying mechanism 3, and the filling mechanism 5 is disposed above the guiding and positioning mechanism 4.

[0028] The guiding and positioning mechanism 4 includes a positioning station 41, a fixing plate 42, a compression spring 43, a base 44, and a return spring 45. The positioning station 41 has a guide groove 411. The base 44 is installed in the guide groove 411. One end of the return spring 45 is fixedly connected to the outside of the base 44, and the other end of the return spring 45 is fixedly connected to the inner wall of the guide groove 411. One end of the compression spring 43 is embedded in the upper end of the base 44, and the other end of the compression spring 43 is fixedly connected to the fixing plate 42.

[0029] In this embodiment, the dual-spring synergy not only buffers mechanical impact but also adapts to different spray bottle sizes through elastic deformation. The guiding structure prevents filling deviation, and the entire process requires no manual intervention.

[0030] Optionally, the conveying mechanism 3 is a belt conveyor, which includes a conveyor belt and a drive assembly, etc., to facilitate the feeding of spray bottles.

[0031] In some embodiments, such as Figure 1 As shown, the pushing mechanism 2 includes a pushing cylinder 21 and a pushing plate 22. The pushing cylinder 21 is fixedly connected to one side of the machine body 1, and the pushing plate 22 is fixedly connected to the output end of the pushing cylinder 21. Several first positioning notches 221 are provided on the side of the pushing plate 22 near the conveying mechanism 3.

[0032] In this embodiment, the pusher plate 22 is driven by the pusher cylinder 21, and the container is precisely guided into the guide positioning mechanism 4 by the first positioning notch 221, ensuring smooth pushing and avoiding deviation. The pusher plate 22 structure can be adapted to different container sizes, improving positioning accuracy and conveying efficiency, reducing the risk of jamming, and realizing high-speed automated filling.

[0033] In some embodiments, such as Figure 4 As shown, a barrier 11 is integrally formed on the other side of the machine body 1. The barrier 11 has a second positioning notch 111 that matches the first positioning notch 221. The first positioning notch 221 and the second positioning notch 111 form a spray bottle positioning groove. The filling mechanism 5 is fixedly connected to the upper end of the barrier 111.

[0034] In this embodiment, the integrally formed enclosure 11 and the push plate 22 work together to form a spray bottle positioning groove by using the precise matching of the first positioning notch 221 and the second positioning notch 111, ensuring that the spray bottle is stably centered during the filling process, avoiding vibration and displacement, and ensuring filling accuracy and reliability of continuous production.

[0035] In some embodiments, such as Figure 1 As shown, the first positioning notch 221 is equipped with an electromagnet 222. The electromagnet 222 magnetically attracts the metal spray bottle to assist in the automated loading and unloading of the spray bottle.

[0036] In some embodiments, such as Figure 2 As shown, a stepper motor 223 is mounted on one end of the pusher plate 22, and a baffle 224 is hinged to one end of the pusher plate 22. The output shaft of the stepper motor 223 is keyed to the baffle 224. The stepper motor 223 drives the baffle 224 to swing precisely, realizing the controllable sorting and positioning of spray bottles, and improving the automation accuracy and smooth operation of the filling line.

[0037] In some embodiments, such as Figure 1 As shown, the filling mechanism 5 includes a filling cylinder 51, a mounting plate 52, and a plurality of filling heads 53. The filling cylinder 51 is fixedly installed at the other end of the machine body 1, and one end of the mounting plate 52 is fixedly connected to the output end of the filling cylinder 51; the filling head 53 is fixedly connected to the other end of the mounting plate 52.

[0038] In this embodiment, the filling cylinder 51 drives the mounting plate 52 to achieve synchronous lifting and lowering of multiple filling heads, enabling multiple bottles to be filled at once, significantly improving production efficiency. The filling head 53 is connected to a container (not shown) containing liquid or gaseous propellant to inject the propellant from the container into the spray bottle.

[0039] In some embodiments, such as Figure 5 As shown, the upper surface of the fixing plate 42 is a raised arc surface 421, which is lower than the upper surface of the positioning station 41. The edge of the raised arc surface 421 is provided with a groove 422 that is adapted to the bottom of the spray bottle.

[0040] In this embodiment, the coordinated design of the raised arc-shaped surface 421 and the slot 422 ensures that the bottom of the spray bottle is precisely engaged and positioned. The structure of the raised arc-shaped surface 421 being lower than the positioning position ensures that the bottle is stable and upright while avoiding excessive friction. The raised arc-shaped surface 421 fits snugly against the bottom of the spray bottle, reducing the risk of the bottle tipping over or shifting.

[0041] In some embodiments, such as Figure 6As shown, the lower end of the fixing plate 42 is integrally formed with a plurality of guide posts 423, the upper end of the base 44 is provided with a guide groove 441 adapted to the guide posts 423, the compression spring 43 is disposed in the guide groove, and the other end of the compression spring 43 is fixedly connected to the guide post 423.

[0042] In this embodiment, the cooperation between the guide post 423 and the guide groove ensures the stable movement of the fixing plate 42 in the vertical direction, preventing offset or jamming. At the same time, the limiting function of the guide groove prevents the compression spring 43 from twisting and failing.

[0043] In some embodiments, such as Figure 4 As shown, the bottom of the guide groove 411 is provided with a limiting groove 412, and the lower end of the base 44 is integrally formed with a limiting plate 442. A ball bearing 443 is installed on the bottom surface of the limiting plate 442, and the limiting plate 442 and the ball bearing 443 are disposed in the limiting groove 412.

[0044] In this embodiment, the horizontal displacement of the base 44 is constrained by the cooperation of the limiting groove 412 and the limiting plate 442, and the ball 443 converts the sliding friction into rolling friction, so that the base slides smoothly along the guide groove, significantly reducing motion resistance and wear.

[0045] As an example, not a limitation, the spray bottles to be filled with propellant are guided from the previous equipment onto the belt conveyor. The spray bottles move along the belt conveyor and are blocked by the baffle 224 rotated out by the stepper motor 223. When four spray bottles enter, the push cylinder 21 extends, and the push plate 22 pushes the spray bottle onto the positioning station 41. Then, the electromagnet 222 on the inner side of the push plate 22 is de-energized, and the push cylinder 21 retracts slightly to provide space for the subsequent automatic positioning of the spray bottles. The raised arc surface 421 on the upper end of the fixing plate 42 can fit against the bottom of the spray bottle, and the slot 422 can wrap around the bottom edge of the spray bottle. Then, the filling cylinder 51 drives the filling head 53 to move down to inject liquid. The compression spring 43 will play a buffering role and at the same time provide... The fixed plate 42 provides time for horizontal movement. As the filling head 53 moves down into the spray bottle, the spray bottle above the fixed plate 42 will automatically adjust to the appropriate position due to the action of the lower ball bearing 443 until the spray bottle is in a vertical position. After the injection is completed, the fixed plate 42 will return to the middle of the guide groove 411 due to the action of the return spring 45. Then the push cylinder 21 extends again, the electromagnet 222 restarts, and the injected spray bottle is attracted. Then it retracts again. When it retracts to the belt conveyor, the electromagnet 222 is de-energized, the push cylinder 21 continues to retract, and the push plate 22 separates from the injected spray bottle. Then the stepper motor 223 rotates ninety degrees, and the baffle 224 is completely retracted into the range of the push plate 22, realizing automatic injection and unloading.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
