Description

Technical Field

[0001] This utility model relates to the field of composite primer coating production technology, specifically a precise quantitative defoaming addition mechanism in composite primer production. Background Technology

[0002] Composite primer coatings are generally composed of special high-molecular synthetic resins, fillers, solvents, and other additives. They are coating materials with excellent alkali resistance and sealing properties. Composite primer coatings have a wide range of applications, suitable for interior and exterior wall decoration of various buildings such as villas, apartments, office buildings, and high-rise buildings. They are used for exterior walls, reliefs, beams, columns, and other irregular wall decorations. They are also suitable for exterior murals and interior decoration, and have color effects similar to granite, marble, and travertine. They are especially suitable for interior decoration of columns, Roman columns, etc., with decorative effects comparable to stone, but more suitable for creating various artistic shapes. In the production process of composite primer coatings, an additive mechanism is needed to transport the coating raw materials to a mixing tank for stirring and mixing.

[0003] The published patent document CN221015758U discloses a production equipment for epoxy zinc-rich primer. This patent document describes a production process using a crushing cylinder, crushing box, a first forward / reverse motor, a second forward / reverse motor, spiral blades, and crushing blades. When producing epoxy zinc-rich primer, the raw materials are first poured into the crushing cylinder through a first feed inlet. Then, the first forward / reverse motor is controlled by a switch, and the spiral shaft and spiral blades work together to crush the raw materials for the first time. The crushed materials then pass through a first screen into the crushing box for a second crushing. This two-stage crushing process reduces production costs and floor space, improving the device's practicality. However, the aforementioned patent document also mentions that air bubbles are easily introduced during the addition and mixing of raw materials, affecting product quality. Utility Model Content

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all 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.

[0022] Please see Figure 1-3This utility model provides a precise quantitative defoaming addition mechanism for composite primer production, including a mixing tank 1, a matching floating cover 2 inside the mixing tank 1, and four stirring motors 4 fixedly installed at the bottom of the mixing tank 1. Several feed pipes 11 are connected through and interference-fitted to the floating cover 2, and a support base 3 is provided above the floating cover 2. Several raw material tanks 5 are fixedly installed on the support base 3. The lower end of the raw material tanks 5 is connected to a connecting pipe 12. The upper end of the feed pipe 11 and the lower end of the connecting pipe 12 are connected to a long flexible hose 13. A stirring shaft 17 is fixedly installed at the output end of the stirring motor 4. The upper end of the stirring shaft 17 passes through the bottom of the mixing tank 1 and a stirring blade 18 is fixedly installed. Four limiting shafts 19 are fixedly connected to the bottom inner wall of the mixing tank 1. The limiting shafts 19 pass through the floating cover 2 and are slidably connected to the floating cover 2 and the limiting shafts 19.

[0023] In this technical solution, composite primer coating material is injected into the raw material tank 5. The raw material enters the mixing tank 1 through the connecting pipe 12, the long hose 13 and the feed pipe 11. The stirring motor 4 drives the stirring shaft 17 and the stirring blade 18 to stir the composite primer coating. Due to the setting of the floating cover 2, the floating cover 2 is always on the surface of the composite primer coating liquid, preventing air from entering above the composite primer coating during the stirring process. This ensures that the composite primer coating after stirring does not contain air bubbles, achieves the defoaming function, and increases the quality of the product.

[0024] In some technical solutions, such as Figure 1-2 As shown, the raw material barrel 5 is provided with an observation window 15, and the outer wall of the raw material barrel 5 is provided with a scale mark 16. The connecting pipe 12 is provided with a solenoid valve 14.

[0025] During use, the opening and closing of the connecting pipe 12 can be controlled at any time by the solenoid valve 14, and the remaining amount of composite primer coating material can be observed through the observation window 15 and the scale 16, so as to realize the function of precise quantitative addition.

[0026] In some technical solutions, such as Figure 1 , Figure 2 and Figure 4 As shown, vertical members 6 are symmetrically fixedly connected to both sides of the mixing tank 1. A vertical groove 8 is opened on the side of the vertical member 6 away from the mixing tank 1. A slider 21 is slidably connected inside the vertical groove 8. Connecting members 7 are symmetrically fixedly connected to both sides of the support base 3. The bottom of one side of the connecting member 7 is fixedly installed with the slider 21. A servo motor 22 is fixedly installed on the top of one of the vertical members 6. A lead screw 23 is fixedly installed on the output end of the servo motor 22. The lead screw 23 is located inside the vertical groove 8. The lower end of the lead screw 23 is rotatably installed with the bottom inner wall of the vertical groove 8. The lead screw 23 passes through a slider 21. The slider 21 and the lead screw 23 are threadedly connected.

[0027] In use, the servo motor 22 drives the lead screw 23 to rotate, and the lead screw 23 can drive the slider 21 to move vertically along the vertical groove 8, thereby driving the support base 3 to move vertically through the connector 7, so as to adjust the height of the support base 3 according to the height of the floating cover 2 and prevent the long hose 13 from being pulled or bent.

[0028] In some technical solutions, such as Figure 3 As shown, a sealing ring is provided between the stirring shaft 17 and the stirring tank 1.

[0029] During use, the sealing ring between the stirring shaft 17 and the stirring tank 1 prevents material leakage during the stirring process.

[0030] In some technical solutions, such as Figure 3 As shown, several baffles 20 are fixedly connected to the top inner wall of the mixing tank 1.

[0031] During use, the baffle 20 prevents the floating cover 2 from contacting the bottom inner wall of the mixing tank 1, thus preventing the composite primer coating from being unable to be added.

[0032] In some technical solutions, such as Figure 1 and Figure 3 As shown, the bottom of the mixing tank 1 is connected to a discharge pipe 9, and a gate valve is installed on the discharge pipe 9.

[0033] In use, the gate valve on the discharge pipe 9 allows for easy opening and closing of the discharge pipe 9, thus facilitating the discharge of the product.

[0034] In some technical solutions, such as Figure 1 As shown, four support legs 10 are fixedly connected at equal intervals along the outer edge of the bottom of the mixing tank 1, and anti-slip pads are fixedly installed at the lower end of the support legs 10.

[0035] When in use, the anti-slip pads at the lower end of the support legs 10 increase the stability of the mixing tank 1.

[0036] Working principle: During use, composite primer coating material is injected into the raw material tank 5. The control solenoid valve 14 can control the opening and closing of the connecting pipe 12 at any time. The remaining amount of composite primer coating material can be observed through the observation window 15 and the scale 16, realizing the precise quantitative addition function. The raw material enters the mixing tank 1 through the connecting pipe 12, the long hose 13 and the feed pipe 11. The stirring motor 4 drives the stirring shaft 17 and the stirring blade 18 to stir the composite primer coating. Due to the setting of the floating cover 2, the floating cover 2 is always on the surface of the composite primer coating liquid, preventing air from entering above the composite primer coating during the stirring process, so that the composite primer coating after stirring does not contain air bubbles, realizing the defoaming function. The servo motor 22 drives the lead screw 23 to rotate, and the lead screw 23 can drive the slider 21 to move vertically along the vertical groove 8, thereby driving the support base 3 to move vertically through the connecting piece 7, so as to adjust the height of the support base 3 according to the height of the floating cover 2, and prevent the long hose 13 from being pulled or bent.

[0037] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application 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 application should be included within the protection scope of this application.
