Description

Technical Field

[0001] This utility model relates to the field of filling equipment, and in particular to a water-based coating filling and packaging equipment. Background Technology

[0002] In the production process of water-based coatings, the filling stage plays a crucial role. High-pressure equipment is typically used to inject the coating into packaging containers. However, conventional filling equipment currently exhibits significant technical deficiencies when performing high-pressure dispensing operations:

[0003] On the one hand, the gap between the paint spraying part and the bottom of the packaging barrel is relatively large. When the high-pressure paint is sprayed out, it will have a strong impact with the bottom of the barrel, resulting in serious splashing. This not only wastes water-based paint, but the splashed paint will also pollute the filling equipment and the surrounding production environment, increasing cleaning costs and workload. At the same time, the paint will entrain a large amount of air during the impact process, forming bubbles. These bubbles will reduce the product quality of water-based paint, affect its performance, reduce filling efficiency, and restrict production progress.

[0004] On the other hand, after the filling process is completed, some water-based paint will remain on the inside of the component used to guide the paint into the packaging barrel. Due to the lack of an effective sealing structure, this residual paint will drip, polluting the production environment, affecting the cleanliness of the production site, and adversely affecting subsequent production operations. Utility Model Content

[0005] The purpose of this utility model is to provide a water-based coating filling and packaging equipment in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a water-based coating filling and packaging equipment, including a discharge pipe and a connecting mechanism for discharging material at its lower part, an extension mechanism is slidably installed inside the connecting mechanism, a scraping mechanism for cleaning the inner wall of the extension mechanism is provided between the connecting mechanism and the extension mechanism, and an anti-drip mechanism adapted to the extension mechanism is installed at the lower port of the connecting mechanism.

[0007] The connecting mechanism includes a connecting sleeve that communicates with the discharge pipe. A perforated plate is installed on the inner side of the upper port of the connecting sleeve, and two guide rings are installed at equal intervals on the inner side of the connecting sleeve.

[0008] The anti-drip mechanism includes a hinge frame fixedly installed on the lower side of the connecting sleeve, and a plug plate rotatably disposed on the hinge frame to open and close with the lower port of the connecting sleeve;

[0009] The extension mechanism includes an extension sleeve that slides inside two guide rings, and a feed seat for controlling the feeding is installed at the top of the extension sleeve.

[0010] As a further description of the above technical solution: the connecting sleeve is fixedly connected to the discharge pipe through a flange, a guide rod is installed through the center of the perforated plate, and a compound spring for supporting the extension sleeve is placed inside the connecting sleeve.

[0011] As a further description of the above technical solution: a sliding ring is installed on the upper side of the outer surface of the extension sleeve, which slides against the inner surface of the connecting sleeve. The sliding ring is located between two guide rings, and the two ends of the compound spring abut against the lower guide ring and the sliding ring.

[0012] As a further description of the above technical solution: the feed seat is coaxially fixedly installed through the top of the extension sleeve, the bottom end of the feed seat is open, the feed seat is slidably installed on the outer surface of the guide rod, the outer side of the feed seat has a number of feed slots through an annular array, and a sealing ring is slidably installed on the inner side of the feed seat.

[0013] As a further description of the above technical solution: the scraping mechanism includes a connecting frame fixedly installed at the bottom end of the connecting sleeve, and a number of push rods for pushing the sealing ring are installed in a circular array on the side of the top of the connecting frame away from the axis.

[0014] As a further description of the above technical solution: a scraper ring that is fixedly installed on the outside of the connecting frame and is in contact with the inside of the extension sleeve.

[0015] As a further description of the above technical solution: a hinge plate that rotates with the hinge frame is fixedly installed on the outside of the blocking plate, a counterweight is fixedly installed on the side of the hinge plate away from the blocking plate, and the extension sleeve abuts against the blocking plate.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0017] When the discharge pipe pours water-based paint into the packaging barrel, the high-pressure sprayed water-based paint pushes the extension mechanism in the connecting mechanism, causing the extension mechanism to extend into the packaging barrel. In this way, when the high-pressure water-based paint is discharged, the gap between the bottom of the packaging barrel is reduced, which effectively avoids the splashing phenomenon caused by the large gap between the water-based paint and the bottom of the barrel when the water-based paint is discharged under high pressure. At the same time, it reduces the formation of air bubbles during the paint impact process, improving filling efficiency and product quality.

[0018] After the extension mechanism completes the feeding and filling of water-based coating and automatically resets, the anti-drip mechanism at the bottom of the connecting mechanism seals the extension mechanism to prevent dripping pollution caused by residual water-based coating on the inside of the extension mechanism after feeding, thereby improving the cleanliness of the production environment.

[0019] When the extension mechanism is reset, the scraping mechanism scrapes off the residual water-based paint on its inner side, reducing the amount of water-based paint residue on the inner side of the extension mechanism and reducing the amount of water-based paint dripping onto the scraping mechanism.

[0027] 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 protection scope of the present utility model.

[0028] like Figure 1 and Figure 2 As shown, the present invention provides a water-based coating filling and packaging equipment, including a discharge pipe 1 and a connecting mechanism 2 for discharging material at its lower part. An extension mechanism 4 is slidably installed inside the connecting mechanism 2. A scraping mechanism 5 for cleaning the inner wall of the extension mechanism 4 is provided between the connecting mechanism 2 and the extension mechanism 4. An anti-drip mechanism 3 adapted to the extension mechanism 4 is installed at the lower port of the connecting mechanism 2.

[0029] In practical use, the high-pressure water-based coating delivered through the discharge pipe 1 pushes the extension mechanism 4 inside the connecting mechanism 2 into the packaging barrel, reducing the distance between the extension mechanism 4 and the bottom of the barrel, minimizing coating splashing and air bubbles, and ensuring stable material feeding. After filling is completed, the extension mechanism 4, no longer propelled by the high-pressure water-based material, automatically resets. During this process, the scraping mechanism 5 simultaneously scrapes the residual coating inside the extension mechanism 4, reducing its residue and the amount dripping onto the scraping mechanism 5. After the extension mechanism 4 has fully reset, the anti-drip mechanism 3 at the bottom of the connecting mechanism 2 immediately seals the extension mechanism 4, preventing residual coating from dripping, avoiding contamination, ensuring a clean production environment, and improving filling efficiency and product quality.

[0030] Specifically, such as Figure 4 and Figure 5 As shown, the connecting mechanism 2 includes a connecting sleeve 21 that communicates with the discharge pipe 1. A perforated plate 22 is installed on the inner side of the upper port of the connecting sleeve 21. Two guide rings 24 are installed at equal intervals on the inner side of the connecting sleeve 21. The connecting sleeve 21 is fixedly connected to the discharge pipe 1 through a flange. A guide rod 23 is installed through the center of the perforated plate 22. A compound spring 25 for supporting the extension sleeve 41 is placed inside the connecting sleeve 21.

[0031] The extension mechanism 4 includes an extension sleeve 41 that slides inside two guide rings 24, and a feed seat 43 for controlling the feed is installed on the top of the extension sleeve 41.

[0032] After the high-pressure water-based coating enters the connecting sleeve 21, it pushes the extension sleeve 41 and the feed seat 43 to slide downwards. The extension sleeve 41 slides downwards and extends into the packaging barrel through the lower port of the connecting sleeve 21. In this way, the extension sleeve 41 makes the water-based coating closer to the bottom of the packaging barrel during filling, effectively avoiding splashing caused by excessive distance between the water-based coating and the bottom of the barrel during high-pressure feeding. At the same time, it reduces the formation of air bubbles during the coating impact, improving filling efficiency and product quality.

[0033] After filling is completed, the feeding of water-based coating is stopped. At this time, the extension sleeve 41 loses the pressure of the high-pressure water-based material. The tension of the compound spring 25 pushes the sliding ring 42 on the outside of the extension sleeve 41, thereby resetting the extension sleeve 41 and preventing the extension sleeve 41 from sticking to the packaging barrel after it extends out, making it inconvenient to remove.

[0034] Furthermore, a sliding ring 42 is installed on the upper side of the outer surface of the extension sleeve 41, which slides against the inner surface of the connecting sleeve 21. The sliding ring 42 is located between two guide rings 24, and the two ends of the compound spring 25 abut against the lower guide ring 24 and the sliding ring 42.

[0035] The feed seat 43 is coaxially fixed and installed through the top of the extension sleeve 41. The bottom of the feed seat 43 is open. The feed seat 43 is slidably installed on the outer surface of the guide rod 23. Several feed slots 431 are opened through the outer ring array of the feed seat 43. A sealing ring 44 is slidably installed on the inner side of the feed seat 43.

[0036] The scraping mechanism 5 includes a connecting frame 51 fixedly installed at the bottom of the connecting sleeve 21. Several push rods 54 that push the sealing ring 44 are installed in a circular array on the side of the top of the connecting frame 51 away from the axis.

[0037] After the water-based coating enters the connecting sleeve 21, it continues to be poured into the feed seat 43 through the feed inlet 431. The water-based coating poured into the feed seat 43 under high pressure will press the sealing ring 44 in the feed seat 43, causing the sealing ring 44 to block the lower port of the feed seat 43. In this way, the water-based coating cannot be discharged outward through the extension sleeve 41. As more and more water-based coating enters the connecting sleeve 21, high pressure is formed to push the extension sleeve 41 downward.

[0038] When the extension sleeve 41 slides down to the designated position, the push rod 54 at the top of the connecting frame 51 pushes the sealing ring 44 upward, causing the sealing ring 44 to move out of place. At this time, the high-pressure water-based coating in the connecting sleeve 21 enters the extension sleeve 41 through the lower port of the feed seat 43, and is filled into the packaging barrel through the extension sleeve 41.

[0039] Specifically, such as Figure 3 and Figure 5 As shown, the anti-drip mechanism 3 includes a hinge frame 31 fixedly installed on the lower side of the connecting sleeve 21. A blocking plate 33 that opens and closes with the lower end of the connecting sleeve 21 is rotatably installed on the hinge frame 31. A hinge plate 32 that rotates with the hinge frame 31 is fixedly installed on the outside of the blocking plate 33. A counterweight block 34 is fixedly installed on the side of the hinge plate 32 away from the blocking plate 33. The extension sleeve 41 abuts against the blocking plate 33.

[0040] When the extension sleeve 41 is pushed downward, the blocking disc 33 is opened. After the extension sleeve 41 is reset and enters the connecting sleeve 21, the weight of the counterweight block 34 pushes the blocking disc 33 to rotate and reset, thus sealing the lower port of the connecting sleeve 21 and the extension sleeve 41.

[0041] Furthermore, a scraper ring 52 that is attached to the inner side of the extension sleeve 41 is fixedly installed on the outer side of the connecting frame 51;

[0042] When the extension sleeve 41 is reset upward, its inner surface is scraped by the scraper ring 52. The scraped water-based paint falls into the packaging barrel, which can reduce the phenomenon of residual water-based paint dripping from the inside of the extension sleeve 41 after the blockage plate 33 is sealed.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
