Description

Technical Field

[0001] The utility model relates to the field of paint production, in particular to an auxiliary material feeding device for paint stirring. Background Art

[0002] In the paint industry, paint is a liquid or powdery material widely used in fields such as construction, automotive, and industry, with decorative, protective, or special functions (such as anti-corrosion, conductivity). When producing paint, various components of the paint (such as pigments, resins, solvents, fillers, and additives, etc.) need to be mixed evenly through a stirring device to form a product with specific properties and appearance. In this process, the stirring device, as the core equipment, promotes the mutual diffusion and mixing of materials through the action of mechanical force, ensuring the uniformity and stability of the paint, which is crucial for the quality of the final product.

[0003] Currently, paint production generally uses intermittent or continuous stirring devices to mix raw materials. During the stirring process, multiple raw materials are put into the stirring container, and through the rotational movement of the stirring paddle, physical actions such as convection occur between the raw materials, thereby achieving uniform mixing. However, in actual production, it often encounters the situation of adding auxiliary materials (such as thickeners, dispersants, etc.) during the stirring process to adjust the performance of the paint or meet specific requirements. The existing method usually pauses the stirring during the stirring process, adds the auxiliary materials into the stirring container through manual operation or other simple devices, and then continues to stir. Although this method can achieve the addition of auxiliary materials, the operation is complex, the efficiency is low, and it is likely to have an adverse impact on the stirring uniformity.

[0004] CN219072706U discloses a liquid paint stirring device, which can carry out continuous raw material supplementation, paint stirring, and paint discharge of paint by using a feeding component, a stirring component, and a discharging component. Therefore, compared with the existing stirring device, it can improve production efficiency and solve the production time wasted due to shutdown for discharging materials.

[0005] However, the feeding method mostly relies on manual experience, and it is impossible to accurately control the addition amount of auxiliary materials, which is likely to lead to excessive or insufficient addition, affecting the final performance of the paint. The feeding process highly depends on the skills and experience of operators, increasing the uncertainty and risk of human error in the production process. Multiple auxiliary materials usually use the same feeding tank when adding, which not only increases the cleaning workload but also may affect the paint quality due to cross-contamination between auxiliary materials. Content of the Utility Model

[0006] In order to overcome the shortcomings of inaccurate feeding amount and the single feeding tank being prone to affecting the feeding effect, the utility model provides an auxiliary material feeding device for paint stirring with precise control.

[0007] An auxiliary material feeding device for coating stirring, comprising a stirring barrel and a stirring assembly. There is a discharge port at the bottom of the stirring barrel, and a stirring assembly is arranged inside the stirring barrel. The stirring assembly mainly consists of a stirring paddle and a motor. The motor rotates the stirring paddle to mix the materials in the stirring barrel. It also includes a feeding assembly, which is used to add auxiliary materials during the stirring process and control the amount of auxiliary materials added.

[0008] Optionally, the feeding assembly includes an electric push rod, a feeding pipe, a pushing rod, a top plate, a bottom plate, a feeding hopper and a volume scale. The electric push rod is installed on the top of the stirring barrel. There are at least three feeding pipes, and the feeding pipes are connected to the stirring barrel. The top plate and the bottom plate are connected by multiple connecting rods in the middle, and the top plate and the bottom plate are slidably connected inside the feeding pipes. One end of the pushing rod is connected to the electric push rod, and the other end is connected to the top of the top plate. A feeding hopper is connected to the top plate. Volume scales are arranged around the electric push rod, and the volume scales correspond to the volumes of the feeding pipes.

[0009] Optionally, it further includes a baffle. A baffle is connected to the lower end of the top plate, which is used to prevent the overflow of auxiliary materials during large-scale feeding. The baffle is slidably connected inside the feeding pipe.

[0010] Optionally, it further includes a scraping plate and a rotating rod. The rotating rod is rotatably connected to the top plate, and a scraping plate is connected to the bottom of the rotating rod. The scraping plate contacts the top surface of the bottom plate.

[0011] Optionally, it further includes a cover plate, which is snap-connected to the feeding hopper to prevent foreign objects from entering the feeding hopper.

[0012] Optionally, it further includes a working indicator light. The working indicator light is installed on the top of the electric push rod. When the electric push rod works, the working indicator light will change its display color to clearly indicate the working state of the electric push rod.

[0013] Optionally, the diameters of the feeding pipes are different, and the corresponding volumes are also different, and the corresponding volume scales also change accordingly.

[0014] Compared with the prior art, the present utility model has the following advantages:

[0015] 1. By controlling the up and down movement of the bottom plate through the electric push rod, the size of the volume between the bottom plate and the feeding pipe is controlled, and the amount of auxiliary materials added each time is controlled through the volume scale, achieving the purpose of precise control. Also, through the transparent baffle, it can prevent the overflow of auxiliary materials and ensure the cleanliness of the upper surface of the stirring barrel.

[0016] 2. Through the rotating scraping plate, the auxiliary materials on the bottom plate are pushed out, thus optimizing the feeding process and achieving the purpose of optimizing the feeding. By closing the discharge hopper with the cover plate, the cleanliness inside the stirring equipment is ensured. Description of the Drawings

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Embodiment: An auxiliary material feeding device for coating mixing, as Figures 1-4 shown, includes a mixing barrel 1 and a mixing assembly 2. A discharge port 101 is provided at the bottom of the mixing barrel 1, and a mixing assembly 2 is provided inside the mixing barrel 1. The mixing assembly 2 is mainly composed of a mixing paddle and a motor. The motor rotates the mixing paddle to mix the materials in the mixing barrel 1 and can ensure the sealing performance. It also includes a feeding assembly for adding auxiliary materials during the mixing process and controlling the amount of auxiliary materials added.

[0024] As Figure 2 and Figure 3As shown in the figure, the feeding assembly includes an electric push rod 3, a feeding pipe 4, a push rod 5, a top plate 6, a bottom plate 7, a feeding hopper 8 and a volume scale 9. The electric push rod 3 is installed on the top of the mixing barrel 1. Four feeding pipes 4 are evenly connected to the mixing barrel 1. The top plate 6 and the bottom plate 7 are connected by multiple connecting rods in the middle. The top plate 6 and the bottom plate 7 are slidably connected in the feeding pipe 4. One end of the push rod 5 is connected to the electric push rod 3, and the other end is connected to the top of the top plate 6. A feeding hopper 8 is connected to the top plate 6. A volume scale 9 is arranged around the electric push rod 3. The volume scale 9 corresponds to the volume of the feeding pipe 4. Four push rods 5 and four rows of volume scales 9 are connected to the electric push rod 3. The diameters of the top plates 6 connected by the four push rods 5 are different, and the diameters of the feeding pipes 4 are also different, and the corresponding volumes are different, and the corresponding volume scales 9 also change accordingly. The diameters of the top plate 6 and the bottom plate 7 corresponding to the upper and lower positions are the same, and the sealing effect with the feeding pipe 4 is good.

[0025] The operator turns on the electric push rod 3, and the electric push rod 3 drives the push rod 5 to move downward. The push rod 5 pushes the top plate 6 and the bottom plate 7 to move downward and slide inside the feeding pipe 4. When the push rod 5 moves to the bottom of the electric push rod 3, raw materials are added through the hopper 8. Since the bottom plate 7 is separated from the bottom of the feeding pipe 4 when the push rod 5 moves downward, the raw materials added through the hopper 8 will directly flow into the mixing barrel 1 through the gap between the bottom plate 7 and the feeding pipe 4. After adding the raw materials, control the electric push rod 3 to pull the push rod 5 upward, and the top plate 6 and the bottom plate 7 move upward. At this time, turn on the mixing component 2 to mix the raw materials. At the same time, determine the amount of auxiliary materials to be added according to the amount of raw materials. Moreover, since the diameters and volumes of the feeding pipes 4 are different, corresponding feeding pipes 4 are selected according to the amount of auxiliary materials. If multiple types of auxiliary materials need to be added, different feeding pipes 4 can be selected to avoid using the same hopper 8 for adding multiple types of auxiliary materials, which not only increases the cleaning workload but also may affect the coating quality due to cross-contamination between the auxiliary materials. Subsequently, control the heights of the top plate 6 and the bottom plate 7 through the electric push rod 3, so as to control the volume of the bowl-shaped container formed by the bottom plate 7 and the feeding pipe 4, and correspond to the volume scale 9 on the electric push rod 3 for the convenience of the operator to directly observe. Subsequently, add the auxiliary materials through the hopper 8, observe the feeding pipe 4 from the side, and confirm whether the height of the auxiliary materials is close to the height of the feeding pipe 4. As the height of the auxiliary materials rises, control the pouring speed to control the addition amount. When the auxiliary materials are close to the top of the feeding pipe 4, stop adding materials, so as to control the amount of auxiliary materials added each time, and the numerical value of the amount of auxiliary materials added can be visually seen, so as to achieve the purpose of controlling the addition of auxiliary materials. Subsequently, push the push rod 5 to the bottom, and the auxiliary materials automatically flow out of the bottom plate 7 and are added to the raw materials. As the mixing component 2 works, the auxiliary materials and the raw materials are fully mixed. After mixing, open the discharge port 101. After the coating passes through the discharge port 101, it is packaged or used directly. After discharging, carry out the next coating mixing process. When the equipment stops working, turn off the electric push rod 3, inject clean water, clean the mixing barrel 1, and then turn off the mixing component 2 and the discharge port 101.

[0026] As Figure 2 shown, it further includes a baffle 10. The lower end of the top plate 6 is connected with a baffle 10. The baffle 10 is used to block the overflow of auxiliary materials during a large amount of feeding. The baffle 10 is slidably connected inside the feeding pipe 4, and the baffle 10 is made of a transparent material. The baffle 10 fits against the inner wall of the feeding pipe 4 and its bottom does not contact the bottom plate 7.

[0027] When adding auxiliary materials, the feeding pipe 4 with a large diameter is used to add a large amount of auxiliary materials, and the feeding pipe 4 with a small diameter is suitable for adding a small amount of auxiliary materials. The baffle 10 fits against the inner wall of the feeding pipe 4, so that when adding auxiliary materials, it can block the excessive auxiliary materials from overflowing the feeding pipe 4. If too much auxiliary material is added, tools can be used to suck out the excess auxiliary material through the opening of the hopper 8 to reduce the waste of auxiliary materials.

[0028] As shown Figure 2 and Figure 4 shown, it further includes a scraping plate 11 and a rotating rod 12. The rotating rod 12 is rotatably connected to the top plate 6. The bottom of the rotating rod 12 is connected with the scraping plate 11, and the scraping plate 11 contacts the top surface of the bottom plate 7.

[0029] When the push rod 5 is pushed to the bottommost position and the auxiliary materials are added into the mixing barrel 1, the worker holds the rotating rod 12, slightly presses it down and then rotates it, thereby driving the scraping plate 11 to rotate, scraping the auxiliary materials on the surface of the bottom plate 7, so that the auxiliary materials fully fall and are added into the mixing barrel 1.

[0030] As shown Figure 2 shown, it further includes a cover plate 13. The cover plate 13 is snap-connected to the feeding hopper 8 and is used to block foreign objects from entering the feeding hopper 8.

[0031] When the mixing barrel 1 is not in use, the cover plate 13 is covered. The cover plate 13 closes the upper port of the feeding hopper 8, thereby blocking the entry of foreign objects and ensuring the cleanliness inside the mixing barrel 1.

[0032] As shown Figure 1 and Figure 2 shown, it further includes a working indicator light 14. The working indicator light 14 is installed on the top of the electric push rod 3. When the electric push rod 3 works, the working indicator light 14 will change the display color to clearly indicate the working state of the electric push rod 3.

[0033] When the electric push rod 3 works, the working indicator light 14 flashes. When the electric push rod 3 raises the push rod 5, the working indicator light 14 flashes one color, and when the electric push rod 3 lowers the push rod 5, it flashes another color. This can not only remind people around that the electric push rod 3 is in a working state, but also facilitate the staff to observe whether there are operation mistakes and whether the rising and falling are reversed.

[0034] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
