[0002] Coatings are organic chemical polymer materials, and the resulting coating film is a type of polymer compound. According to the modern classification of chemical products, coatings belong to fine chemical products. Modern coatings are gradually becoming a type of multifunctional engineering material and an important industry in the chemical industry. In the process of coating spraying, a conveying device and a spray gun are required for use.

[0003] Currently, existing traditional paint conveying equipment suffers from insufficient mixing during use, which can easily lead to paint sedimentation. In addition, its size makes it inconvenient to move and unsuitable for use in confined spaces. Furthermore, paint residue in the spray gun pipeline after use can easily settle and solidify, thus affecting the next use of the paint conveying device.

[0004] Based on this, the present invention designs a small paint conveying device to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a small paint delivery device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a small paint conveying device, comprising a stainless steel barrel, a barrel lid, a pneumatic agitator, a back pressure valve, a suction pipe, a paint return pipe, a lifting cylinder, a pump, a paint filter, a paint pressure stabilizer, a manual three-speed lifting valve, a base frame, and casters. The bottom of the stainless steel barrel is provided with a base frame, and casters are fixedly installed at each of the four corners of the base frame. A column is fixedly installed at the rear of the stainless steel barrel at the upper end of the base frame, and a lifting cylinder is installed inside the column. A manual three-speed lifting valve is fixedly installed on the left side of the lifting cylinder. A pump is fixedly installed at the top of the telescopic end of the lifting cylinder. A bucket cover is fixedly connected to the front of the telescopic end of the lifting cylinder. The bucket cover is fastened to the upper end of the stainless steel bucket. A paint filter is fixedly installed at the left outlet end of the pump. A paint pressure regulator is fixedly installed at the outlet end of the paint filter. The outlet of the paint pressure regulator is connected to the spray gun pipeline. A pneumatic agitator is fixedly installed at the center of the upper end of the bucket cover. A back pressure valve is fixedly installed at the upper end of the left bucket cover of the pneumatic agitator. A suction pipe and a paint return pipe are fixedly installed at the upper end of the right bucket cover of the pneumatic agitator.

[0007] As a preferred embodiment of this utility model, the conveying end of the pneumatic stirrer is fixedly connected to a stirring rod, and the bottom end of the stirring rod is provided with stirring blades. The stirring blades and the stirring rod are movably disposed inside the stainless steel barrel.

[0008] As a preferred technical solution of this utility model, the circumference of the stirring blade is provided with an upward-turned toothed edge and a downward-turned toothed edge, and the upward-turned toothed edge and the downward-turned toothed edge are distributed alternately.

[0009] As a preferred embodiment of this utility model, the lower ends of both the suction pipe and the paint return pipe extend into the interior of the stainless steel barrel, and the upper end of the suction pipe is connected to the right inlet end of the pump via a connecting pipe.

[0011] As a preferred embodiment of this utility model, the stainless steel barrel is provided with symmetrical handles on its left and right sides.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model is equipped with a pneumatic agitator, which is powerful and quiet, and does not require electricity, making it safer. At the same time, the agitator blades adopt a toothed edge design with up and down folding, which increases the contact area with the paint and is more efficient than the traditional three- or five-blade blades. The agitation is more thorough and avoids paint deposition, making it more suitable for water-based paints with higher viscosity. The entire tank is made of 304 stainless steel, which has strong corrosion resistance, is easy to clean, and has a small and compact design that reduces space occupation, making it more suitable for small spaces. The four universal wheels at the bottom make it easy to move and change the place of use, making it more user-friendly and convenient.

[0014] 2. When in use, the hydraulic lifting cylinder configured inside the column has strong power and can lift the pump, filter, bucket lid, etc., making it easy to add paint directly. The design of the spray gun pipeline and the bucket body allows the paint to circulate internally in the bucket body and pipeline, avoiding the paint from settling and solidifying in the pipeline, protecting the equipment from pipeline sedimentation, and saving paint at the same time.

Figure 1-3 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Example

[0022] Please refer to Figure 1-3 This utility model provides the following technical solution: a small paint conveying device, including a stainless steel barrel 1, a barrel cover 2, a pneumatic agitator 3, a back pressure valve 4, a suction pipe 5, a paint return pipe 6, a lifting cylinder 7, a pump 8, a paint filter 9, a paint pressure stabilizer 10, a manual three-speed lifting valve 11, a base frame 12, and casters 13. The bottom of the stainless steel barrel 1 is provided with a base frame 12, and casters 13 are fixedly installed at the four corners of the base frame 12. A column is fixedly installed at the rear of the stainless steel barrel 1 at the upper end of the base frame 12, and a lifting cylinder 7 is installed inside the column. A manual three-speed valve is fixedly installed on the left side of the lifting cylinder 7. A pump 8 is fixedly installed at the top of the telescopic end of the lifting valve 11 and the lifting cylinder 7. A bucket cover 2 is fixedly connected to the front of the telescopic end of the lifting cylinder 7. The bucket cover 2 is fastened to the upper end of the stainless steel bucket body 1. A paint filter 9 is fixedly installed at the left outlet end of the pump 8. A paint pressure regulator 10 is fixedly installed at the outlet end of the paint filter 9. The outlet of the paint pressure regulator 10 is connected to the spray gun pipeline. A pneumatic agitator 3 is fixedly installed at the center of the upper end of the bucket cover 2. A back pressure valve 4 is fixedly installed at the upper end of the bucket cover 2 to the left of the pneumatic agitator 3. A suction pipe 5 and a paint return pipe 6 are fixedly installed at the upper end of the bucket cover 2 to the right of the pneumatic agitator 3.

[0023] The pneumatic stirrer 3 is fixedly connected to the conveying end with a stirring rod 301. The bottom end of the stirring rod 301 is provided with a stirring blade 302. The stirring blade 302 and the stirring rod 301 are movably arranged inside the stainless steel barrel 1.

[0024] The circumference of the stirring blade 302 is provided with an upward-curved toothed edge and a downward-curved toothed edge, and the upward-curved toothed edge and the downward-curved toothed edge are distributed alternately.

[0025] The lower ends of the suction pipe 5 and the paint return pipe 6 both extend into the interior of the stainless steel barrel 1, and the upper end of the suction pipe 5 is connected to the right inlet end of the pump 8 through a connecting pipe.

[0026] The suction assembly is formed by connecting the suction pipe 5, pump 8, paint filter 9 and paint pressure stabilizer 10 to achieve stable pressure delivery of paint in the stainless steel barrel 1, ensuring the spraying effect. The pneumatic agitator 3 on the barrel cover 2 can fully stir the paint in the stainless steel barrel 1 to ensure the uniformity of the paint and avoid sedimentation.

[0027] The lifting cylinder installed inside the column allows for three-level control: rising, falling, and hovering, under the control of the manual three-level lifting valve on the left side.

[0028] Please refer to Figure 1 and Figure 2 The upper end of the paint return pipe 6 is provided with a first valve 601. The first valve 601 is connected to the outlet end of the back pressure valve 4 through a connecting pipe. The inlet end of the back pressure valve 4 is connected to the spray gun pipeline through a connecting pipe.

[0029] The back pressure valve 4 and the paint return pipe 6 are connected by a connecting pipe to form a return loop. When the paint delivery device is not in use, the paint in the spray gun pipe can return to the stainless steel barrel 1, thus avoiding pipe blockage.

[0030] Please refer to Figure 3 The stainless steel barrel body 1 has symmetrical handles 101 on its left and right sides.

[0031] The stainless steel barrel 1 is symmetrically provided with handles 101 on both sides, which makes it convenient to hold the barrel and provides a gripping position for the hand when moving the stainless steel barrel 1.

[0032] The working principle and usage process of this utility model are as follows: In specific use, the lifting cylinder 7 raises the lid 2 to open the lid 2 on the stainless steel barrel 1, and paint is added into the stainless steel barrel 1. Then, the lifting cylinder 7 lowers again until the lid 2 is closed on the stainless steel barrel 1. The pneumatic agitator 3 drives the agitator rod 301 and the agitator blade 302 to rotate synchronously, thereby agitating the raw materials in the stainless steel barrel 1 and preventing sedimentation. Then, the pump 8 uses siphon to suck the paint from the suction pipe 5 and delivers it to the paint filter 9. The paint is filtered through the paint filter 9, and then the filtered paint is conveyed to the paint pressure regulator 10. The paint pressure regulator 10 provides stable hydraulic pressure for the paint to be sprayed out. Then the paint is sprayed onto the product through the spray gun installed at the discharge end of the paint pressure regulator 10. After the paint conveying device is used, the back pressure valve 4 and the paint return pipe 6 form a return design with the spray gun pipeline and the barrel, allowing the paint to circulate internally in the barrel and pipeline. This avoids the paint from settling and solidifying in the pipeline when not in production, and at the same time saves paint.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
