Description

Technical Field

[0001] This application relates to the field of paint production equipment technology, and in particular to a paint filling structure. Background Technology

[0002] Coatings are generally divided into water-based and oil-based coatings. In addition, coating additives are also used as auxiliary materials added during the production or use of coatings. Both coatings and coating additives are usually transported in the form of storage tanks. Therefore, the bottling process of coatings is very important for the stability during transportation and storage.

[0003] A Chinese patent with publication number CN112441542A discloses a paint filling device, which includes a conveyor belt for conveying a number of bottles. A storage tank is set above the conveyor belt. The storage tank is connected to a filling head through a feeding pipe and a solenoid valve. The filling head is aligned with the top opening of the bottle for filling. After filling, the filled bottles are conveyed backward, and the bottles to be filled move to the filling station for filling.

[0004] The aforementioned technologies have the following drawbacks: after filling, a small amount of liquid droplets may remain on the bottom of the filling head. If these droplets drip during non-filling processes, they may remain on the bottle body or conveyor belt, which needs to be improved. Utility Model Content

[0005] In order to reduce the impact of droplets adhering to the bottom of the filling head on the bottle or conveyor belt during non-filling processes, this application provides a coating filling structure.

[0006] The purpose of this application is to overcome the above-mentioned technical problems and provide a coating filling structure. A paint filling structure includes a frame, a conveyor belt and a filling assembly located above the conveyor belt, the filling assembly including a filling head, and a liquid receiving plate provided on the frame via a telescopic drive component. The liquid receiving plate is located below the filling head, and a liquid receiving trough is provided on the top of the liquid receiving plate. The liquid receiving trough is provided with absorbent cotton inside.

[0007] By adopting the above technical solution, the liquid receiving plate can be moved to the bottom of the filling head using the telescopic drive component. The liquid receiving tank can collect the liquid droplets hanging on the bottom wall of the filling head, and the absorbent cotton can absorb the droplets, reducing the impact of the liquid droplets hanging on the bottom wall of the filling head on the bottle body or conveyor belt during non-filling processes.

[0008] Preferably, the bottom of the liquid receiving tank and the top surface of the liquid-absorbing cotton are both concave arc surfaces, a negative pressure port is provided at the bottom of the liquid receiving tank, and a negative pressure mechanism connected to the negative pressure port is provided at the bottom of the liquid receiving plate.

[0009] By adopting the above technical solution, the bottom of the liquid receiving tank and the top surface of the absorbent cotton are concave arc surfaces, which are conducive to the accumulation of liquid droplets; the negative pressure mechanism generates negative pressure in the liquid receiving tank through the negative pressure port, which can accelerate the absorption of liquid droplets by the absorbent cotton, further improve the efficiency and effect of receiving liquid droplets, and thus better reduce the impact of the liquid droplets hanging on the wall on the bottle body and the conveyor belt.

[0010] Preferably, the liquid receiving tank is provided with a partition, the partition has a plurality of through vent holes, and a reserved cavity is formed inside the liquid receiving tank below the partition.

[0011] By adopting the above technical solution, a baffle with ventilated holes is set in the liquid receiving tank and a reserved cavity is formed below the baffle, which can allow air to circulate better, improve the uniformity of negative pressure, and further enhance the ability to absorb liquid droplets.

[0012] Preferably, the frame is provided with a liquid collection bottle, the liquid collection bottle is provided with a liquid inlet and a gas outlet, and the liquid inlet is connected to a negative pressure mechanism through a pipe.

[0013] By adopting the above technical solution, the liquid in the receiving tank can flow into the collection bottle through the pipeline under negative pressure for collection, reducing the impact of liquid residue on the receiving plate and the surrounding environment.

[0014] Preferably, the air outlet is provided with splash-proof cotton.

[0015] By adopting the above technical solution, the air outlet of the negative pressure mechanism continuously sprays air containing paint droplets. Therefore, by setting anti-splash cotton at the air outlet, this application can reduce liquid splashing out of the collection bottle.

[0016] Preferably, the liquid collection bottle includes a detachable and connected cap and a bottle body, with the liquid inlet and air outlet both located on the cap, and the cap connected to the frame.

[0017] By adopting the above technical solution, the liquid collection bottle is connected to the negative pressure mechanism through a pipeline to store the collected liquid. Furthermore, the liquid collection bottle adopts a detachable bottle cap and bottle body, and the liquid inlet and air outlet are located on the bottle cap, which is connected to the frame, making it easier to clean and maintain the liquid collection bottle and facilitate the regular treatment of the coating inside the liquid collection bottle.

[0018] Preferably, the bottle body is provided with a transparent observation window.

[0019] By adopting the above technical solution, the collection bottle is composed of a detachable cap and a bottle body, which facilitates cleaning of the collection bottle; while the transparent observation window on the bottle body makes it easy to observe the collection of liquid in the collection bottle, so that the operator knows when the liquid in the bottle needs to be disposed of.

[0020] Preferably, the absorbent cotton has a frame on its outer edge, and the frame is connected to a lever. The lever is located above the liquid receiving plate and its edge extends out of the liquid receiving plate.

[0021] By adopting the above technical solution, a frame is set on the outer edge of the absorbent cotton and a lever is connected. The lever is located above the liquid receiving plate and its edge extends out of the liquid receiving plate, making it convenient for users to grab the lever to take out the absorbent cotton for replacement or cleaning.

[0025] The technical solutions in the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. The described embodiments are only possible technical implementations of this utility model, but are not limited thereto. Other embodiments obtained by those skilled in the art in conjunction with the embodiments of this utility model without creative effort are also within the protection scope of this utility model.

[0026] This application mainly adopts a solution of collecting droplets adhering to the wall of the filling head using a liquid receiving plate, which achieves the effect of reducing the impact of droplets on the bottle body or conveyor belt when not filling. The following is a further detailed description of this application. Example

[0027] Reference Figure 1 The paint filling structure provided in this application includes a frame 1, a conveyor belt 11, a filling assembly 12, a telescopic drive 13, and a drip receiving plate 14. Both the conveyor belt 11 and the filling assembly 12 are mounted on the frame 1, with the filling assembly 12 positioned above the conveyor belt 11. The bottom of the filling assembly 12 has a filling head 121 for filling paint cans. The telescopic drive 13 is also mounted on the frame 1 and connected to the drip receiving plate 14, driving the drip receiving plate 14 to extend and retract below the filling head 121. During the filling process, the telescopic drive 13 retracts below the filling head 121 to perform normal filling operations. After the filling head 121 has finished its work, the telescopic drive 13 can move the drip receiving plate 14 below the filling head 121 to promptly collect any drips adhering to the bottom wall of the filling head 121, thereby reducing the impact of drips on the bottle body 22 or the conveyor belt 11 during non-filling processes. This layout allows all components to work together effectively during the filling process, ensuring the efficient completion of the paint filling operation.

[0028] Specifically, the frame 1, as the supporting foundation of the entire structure, has sufficient strength and stability. It can be made of metal materials such as welded steel, or aluminum alloy to reduce the overall weight. The conveyor belt 11 is installed on the frame 1 and is mainly used for conveying canned bottles. It can be a common belt conveyor 11 or a chain conveyor 11, depending on the actual production needs.

[0029] The filling assembly 12 is connected to the filling head 121 via a feed pipe (not shown in the figure), and the filling of the coating can be achieved under the control of a solenoid valve. The filling head 121 can be made of stainless steel to ensure its corrosion resistance, and its shape and size must be adapted to the size and shape of the bottle opening.

[0030] The telescopic drive component 13 is used to control the position of the liquid receiving plate 14. Common telescopic drive components 13 include cylinders or electric push rods. Taking a cylinder as an example, it moves the liquid receiving plate 14 by extending and retracting the piston rod. The cylinder is mounted on the frame 1, and the end of the piston rod is fixedly connected to the liquid receiving plate 14. When the cylinder is activated, the liquid receiving plate 14 can move below the filling head 121.

[0031] Reference Figure 1 and Figure 2The liquid receiving plate 14 has a liquid receiving groove 140 on its top, and absorbent cotton 15 is placed inside the liquid receiving groove 140. The liquid receiving plate 14 can be made of plastic or metal, and the liquid receiving groove 140 is a recessed shape with an open top. The absorbent cotton 15 has good water absorption and can quickly absorb the droplets in the liquid receiving groove 140 to prevent the droplets from overflowing. The absorbent cotton 15 can be made of sponge or polyester fiber.

[0032] The absorbent cotton 15 has a frame 151 fixedly attached to its outer edge to enhance the overall rigidity of the outer edge. A lever 152 is also connected to the edge of the frame 151, with the lever 152 positioned above the liquid receiving plate 14 and extending beyond its edge. The frame 151 can be made of plastic and serves to secure the absorbent cotton 15. The lever 152 facilitates replacement of the absorbent cotton 15 by the operator; when replacement is needed, simply pull the lever 152 to easily remove the absorbent cotton 15.

[0033] The bottom of the liquid receiving tank 140 and the top surface of the absorbent cotton 15 are both concave arc surfaces. This design helps droplets converge towards the center, facilitating better collection and absorption of dripping paint droplets. A negative pressure port 141 is provided at the bottom of the liquid receiving tank 140, and a negative pressure mechanism 16 connected to the negative pressure port 141 is connected to the bottom of the liquid receiving plate 14 via a pipe. The negative pressure mechanism 16 can be a vacuum pump. When the vacuum pump operates, a negative pressure is created within the liquid receiving tank 140, which can more effectively draw droplets from inside the absorbent cotton 15 into the liquid receiving tank 140.

[0034] In addition, a partition 17 is provided inside the liquid receiving tank 140, and several through-holes 170 are provided on the partition 17. A reserved cavity 171 is formed inside the liquid receiving tank 140 below the partition 17. The partition 17 can be a plastic plate, and its function is to separate the absorbent cotton 15 and the reserved cavity 171 while ensuring air permeability. The size and number of the vent holes 170 should be designed according to the actual situation to ensure that the negative pressure can be evenly distributed throughout the liquid receiving tank 140.

[0035] Reference Figure 1 and Figure 3 The frame 1 is also equipped with a collection bottle 2, which includes a detachably connected cap 21 and a bottle body 22. The cap 21 has a liquid inlet 23 and an air outlet 24, and is fixedly connected to the frame 1. The liquid inlet 23 is connected to the negative pressure mechanism 16 through a pipe. The collection bottle 2 is used to collect paint droplets sucked from the receiving tank 140, which facilitates centralized processing of the collected paint and avoids secondary pollution. An anti-splash cotton 25 is provided at the air outlet 24 to prevent the liquid in the collection bottle 2 from splashing to the outside, ensuring a clean working environment. The anti-splash cotton 25 can be made of a material with good air permeability and strong adsorption.

[0036] The bottle cap 21 can be detachably connected to the frame 1 via a threaded connection. This detachable design facilitates cleaning and maintenance of the collection bottle 2. In addition, a transparent observation window 26 is provided on the side wall of the bottle body 22, through which the liquid level in the collection bottle 2 can be monitored in real time, allowing staff to handle the situation promptly.

[0037] The implementation principle of this embodiment is as follows: During the paint filling process, the conveyor belt 11 transports the canning bottle to the filling station, and the filling head 121 of the filling assembly 12 aligns with the canning bottle to fill the paint. After filling, the telescopic drive component 13 moves the liquid receiving plate 14 to below the filling head 121. The droplets hanging on the bottom wall of the filling head 121 fall into the liquid receiving groove 140 of the liquid receiving plate 14 and are absorbed by the absorbent cotton 15. At the same time, the negative pressure mechanism 16 works, forming a negative pressure in the liquid receiving groove 140 through the negative pressure port 141, accelerating the absorption of the droplets. The droplets enter the reserved cavity 171 through the vent hole 170 on the partition 17, and are then sucked into the collection bottle 2 through the pipe. The operator can check the liquid level through the observation window 26 of the collection bottle 2. When the liquid level reaches a certain height, the bottle cap 21 of the collection bottle 2 can be removed for cleaning. In addition, if the absorbent cotton 15 is saturated, it can be replaced by pulling the lever 152. This embodiment effectively reduces the impact of liquid droplets adhering to the bottom of the filling head 121 on the bottle body 22 or conveyor belt 11 during non-filling processes through the coordinated work of various components, thereby improving production stability and product quality. It represents a significant improvement and enhancement compared to existing technologies.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
