Description

Technical Field

[0001] This utility model relates to the technical field of paint supply equipment, and in particular to a pneumatic paint supply device. Background Technology

[0002] In the production of enameled wire, enamel replenishment is necessary. Traditionally, this involves manually emptying the enamel from the buckets for production line use. This method exposes workers to direct contact with the enamel, increasing the risk of chemical injury. Furthermore, manually moving the buckets and emptying the enamel is time-consuming and labor-intensive, significantly impacting replenishment efficiency. While an extraction device can be installed inside the buckets, this eliminates the need for emptying. However, prolonged standing can lead to sedimentation and stratification of the enamel, resulting in differences in composition and properties between the upper and lower layers. This affects coating quality, obstructs enamel flow in the enamel conduit, and can even cause blockages, severely impacting the overall enamel replenishment efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a pneumatic paint supply device to solve the technical problem of paint sedimentation and clumping leading to pipe blockage in existing technologies.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a pneumatic paint supply device, comprising a paint bucket containing paint, a first adapter and a second adapter provided on the top of the paint bucket, both the first adapter and the second adapter communicating with the interior of the paint bucket, a paint guide tube extending into the paint bucket being connected to one end of the first adapter, a first gear being sleeved on one end of the paint guide tube located inside the first adapter, a motor being provided outside the first adapter, the output shaft of the motor extending into the first adapter and sleeved with a second gear, the second gear meshing with the first gear, a stirring component being provided on the outer surface of the paint guide tube, and a pneumatic pump being connected to the second adapter via an air supply pipe.

[0005] Furthermore, one end of the second adapter extends into the paint bucket, and the end of the second adapter extending into the paint bucket is higher than the surface of the paint liquid.

[0006] Furthermore, the end of the paint pipe furthest from the first adapter is provided with a beveled section.

[0007] Furthermore, the stirring component is a stirring rod, and there are multiple stirring rods arranged at intervals along the circumference of the paint inlet pipe.

[0008] Furthermore, the top of the paint bucket is provided with a first threaded hole and a second threaded hole. One end of the first adapter is screwed into the first threaded hole, and the other end is screwed into the shut-off valve. One end of the second adapter is screwed into the second threaded hole, and the other end is connected to the air supply pipe.

[0009] Furthermore, the end of the shut-off valve furthest from the first adapter is connected to a paint supply pipe.

[0010] Furthermore, the space between the first adapter and the first threaded hole is filled with sealing grease.

[0011] Furthermore, the second adapter is screwed onto the air supply pipe.

[0012] Furthermore, the space between the second adapter and the second threaded hole is filled with sealing grease.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] (1) This utility model provides a pneumatic paint supply device, which drives the paint pipe to rotate by a motor, thereby driving the stirring component to rotate, so that the paint pipe can stir the paint in the paint bucket while transporting the paint, preventing the paint from settling and clumping, thereby improving the smoothness of the paint flow along the paint pipe and effectively avoiding the occurrence of pipe blockage accidents.

[0015] (2) This utility model provides a pneumatic paint supply device. Compressed air or inert gas is sent into the paint bucket through the second adapter by a pneumatic pump. As the gas is continuously injected, the air pressure in the paint bucket gradually increases. A significant air pressure difference is formed between the high-pressure gas inside the paint bucket and the external environment. Under the action of the air pressure difference, the paint in the paint bucket continuously flows along the paint inlet pipe to the first adapter for paint supply. This helps to reduce the chance of workers directly contacting the paint, reduce the risk of chemical injury, and save manpower and time costs, thereby improving the efficiency of paint delivery and supply.

[0016] (3) The adapter is installed on the paint bucket using a threaded connection, which allows for quick replacement of the paint bucket after the previous one is used up, saving working time. Attached Figure Description

[0020] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] like Figure 1-2 As shown, the pneumatic paint supply device of this utility model embodiment includes a paint bucket 1 containing paint liquid 9. A first adapter 3 and a second adapter 6 are provided on the top of the paint bucket 1. Both the first adapter 3 and the second adapter 6 are connected to the inside of the paint bucket 1. One end of the first adapter 3 is movably connected to a paint guide tube 2 that extends into the paint bucket 1. A first gear 12 is sleeved on one end of the paint guide tube 2 located inside the first adapter 3. A motor 14 is provided outside the first adapter 3. The output shaft of the motor 14 extends into the first adapter 3 and is sleeved with a second gear 13. The second gear 13 meshes with the first gear 12. A stirring component 202 is also provided on the outer surface of the paint guide tube 2. One end of the second adapter 6 extends into the paint bucket 1, and the other end of the second adapter 6 is connected to a pneumatic pump 8 through an air supply pipe 7. Compressed air or inert gas is pumped into the paint tank 1 via a pneumatic pump 8 and a second adapter 6. As gas is continuously injected, the pressure inside the paint tank 1 gradually increases, creating a significant pressure difference between the high-pressure gas inside and the external environment. This pressure difference causes the paint liquid 9 inside the paint tank 1 to continuously flow along the paint inlet pipe 2 to the first adapter 3, where it is then directed to the paint liquid coating device for replenishment. This reduces the chance of workers directly contacting the paint liquid 9, lowering the risk of chemical injury, and saving labor and time costs. It also improves the efficiency of paint liquid 9 delivery and replenishment. The motor 14 drives the paint inlet pipe 2 to rotate, which in turn drives the stirring component 202 to rotate. This allows the paint inlet pipe 2 to simultaneously transport and stir the paint liquid 9 within the paint tank 1, preventing sedimentation and clumping, thus improving the smoothness of the paint liquid 9 flow along the paint inlet pipe 2 and effectively avoiding pipe blockage accidents. When the pneumatic pump 8 stops, the motor 14 can continue to drive the paint inlet pipe 2 to rotate and stir the paint liquid 9.

[0022] Preferably, the stirring component 202 can be a stirring rod or a stirring block, and there is no limitation. In this embodiment, the stirring component 202 is a stirring rod, and there are multiple stirring rods. The multiple stirring rods are arranged at intervals along the circumference of the paint pipe 2. The multiple stirring rods can rotate under the drive of the paint pipe 2, which can increase the contact area between the stirring rod and the paint liquid 9, thereby improving the stirring efficiency of the paint liquid 9.

[0023] Specifically, please refer to Figure 1The end of the second adapter 6 that extends into the paint bucket 1 is higher than the surface of the paint liquid 9. The paint inlet pipe 2 extends into the paint liquid 9, and the end of the paint inlet pipe 2 away from the first adapter 3 is provided with a beveled part 201, so that the paint liquid 9 enters the paint inlet pipe 2 smoothly along the beveled surface under the action of air pressure difference, which helps to reduce turbulence and energy loss.

[0024] Specifically, please refer to Figure 1 The top of the paint bucket 1 is provided with a first threaded hole and a second threaded hole. One end of the first adapter 3 has an external thread on its outer wall corresponding to the first threaded hole. A bearing 11 is installed on the inner wall of the first adapter 3. One end of the first adapter 3 extends into the paint bucket 1, mates with the first threaded hole via the external thread, and is connected to the paint supply pipe 2 via the bearing 11. Sealing grease is filled between the first adapter 3 and the first threaded hole to improve the sealing effect between the first adapter 3 and the paint bucket 1. A stop valve 4 is screwed to the other end of the first adapter 3. The end of the stop valve 4 away from the first adapter 3 is connected to a paint supply pipe 5. A handle 10 is also provided on the stop valve 4, which can be turned to control the opening and closing of the stop valve 4. When paint 9 needs to be replenished, the motor 14, the pneumatic pump 8, and the stop valve 4 are turned on, allowing the paint 9 in the paint supply pipe 2 to pass through the stop valve 4 into the paint supply pipe 5, thereby replenishing the paint 9 of the production line. When the paint liquid 9 has been delivered and the paint bucket 1 needs to be replaced, turn off the motor 14 and the pneumatic pump 8, and then close the shut-off valve 4 to prevent the paint liquid 9 in the paint supply pipe 5 from flowing back.

[0025] like Figure 1 As shown, one end of the second adapter 6 has an external thread corresponding to the second threaded hole on the top of the paint bucket 1. The second adapter 6 is installed in the second threaded hole, and sealing grease is filled between the second adapter 6 and the second threaded hole to improve the sealing effect between the second adapter 6 and the paint bucket 1. The other end of the second adapter 6 has an internal thread corresponding to the external thread of one end of the air supply pipe 7. One end of the air supply pipe 7 is screwed into the second adapter 6, and the other end of the air supply pipe 7 is connected to the pneumatic pump 8.

[0026] Specific implementation process: The top of the paint bucket 1, which is transported to the production line, has a first threaded hole and a second threaded hole. A pre-machined first adapter 3, containing a bearing 11, a first gear 12, a second gear 13, and a motor 14, is fitted onto one end of the paint inlet pipe 2, allowing the paint inlet pipe 2 to pass through the first gear 12 and be fitted into the bearing 11. The paint inlet pipe 2 is then inserted into the paint bucket 1 through the first threaded hole, and the first adapter 3 is installed in the first threaded hole. A shut-off valve 4 is then installed on the other end of the first adapter 3, and the other end of the shut-off valve 4 is installed on the paint supply pipe 5. Next, a second adapter 6 is installed in the second threaded hole, and one end of the air supply pipe 7 is connected to the second adapter 6, while the other end of the air supply pipe 7 is connected to the pneumatic pump 8. Open the shut-off valve 4, and turn on the pneumatic pump 8 and motor 14. The pneumatic pump 8 sends compressed air or inert gas into the paint tank 1, creating a pressure difference between the high-pressure gas inside the paint tank 1 and the external environment. Under the action of the pressure difference, the paint liquid 9 in the paint tank 1 continuously flows along the paint inlet pipe 2 through the shut-off valve 4 to the paint supply pipe 5, continuously supplying paint liquid 9 to the production line. At the same time, the motor 14 drives the paint inlet pipe 2 to rotate the stirring component 202, so that the paint inlet pipe 2 can stir the paint liquid 9 in the paint tank 1 while supplying it, preventing the paint liquid 9 from settling and clumping. After the paint liquid 9 in the paint tank 1 has been supplied, turn off the motor 14, pneumatic pump 8, and shut-off valve 4, replace the paint tank 1, and then turn them back on to continue replenishing the paint liquid 9.
