Description

Technical Field

[0001] This utility model relates to the field of powder coating production technology, specifically to a powder coating color matching device. Background Technology

[0002] Powder coatings are solid powdered synthetic resin coatings composed of solid resins, pigments, fillers, and additives. Due to their environmental friendliness, high utilization rate, and excellent coating performance, powder coatings are widely used in the field of metal surface coating. The production of powder coatings involves pouring various powder coatings requiring different colors into a mixing tank according to the formula, and thoroughly mixing them to create different colors. Currently, most common powder coating mixing equipment uses a mixing tank structure, with a motor driving a stirring shaft and blades to mechanically mix the materials. However, in practical applications, existing equipment still has several technical limitations: First, materials tend to accumulate or stick to the bottom and side walls of the tank during mixing, leading to mixing dead zones and affecting the uniformity and efficiency of color mixing; second, residues often remain during unloading, not only causing material waste but also potentially causing cross-contamination between batches.

[0003] For example, Chinese patent CN222342675U discloses a powder coating color mixing machine, including a shaking component. A color mixing component is rotatably mounted on top of the shaking component. The shaking component includes a base plate, and a vertical plate is fixedly mounted on both sides of the top surface of the base plate. A threaded rod is rotatably mounted on the front between the two vertical plates. This powder coating color mixing machine stirs the coating raw materials and pigments through mixing blades. While stirring and mixing through the mixing blades, the color mixing box at the top of the base can be moved back and forth by controlling the reciprocating movement of the base. The reciprocating movement of the color mixing box can assist in shaking and evenly mixing the coating raw materials and pigments inside. Furthermore, when the base moves back and forth, the driven gear rotates, which drives the rotating shaft to rotate. The rotation of the rotating shaft drives the color mixing box to rotate in both forward and reverse directions while it is moving back and forth, thereby further improving the color mixing efficiency.

[0004] However, in this patent, the discharge port is located on the side wall of the color mixing tank, which is not conducive to the discharge of materials. At the same time, materials tend to accumulate at the bottom of the color mixing tank, resulting in insufficient mixing. In addition, materials adhering to the inner wall of the color mixing tank cannot be cleaned in time, resulting in many mixing dead zones. The materials cannot be evenly mixed in the tank, and the material residue in the tank is high. This not only leads to the waste of expensive pigments and increases production costs, but also causes cross-contamination between different batches and different colors of materials, affecting the purity of the product color. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the defects of the existing technology and provide a powder coating color matching device that not only significantly improves the color matching effect and production efficiency of powder coatings, but also performs well in reducing losses, preventing pollution and automating operation, and has good industrial application value and economic benefits.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a powder coating color matching device, including a box body, the box body including a color matching tank located at the top and a feeding box located at the bottom, the top of the feeding box is provided with a connection port, the color matching tank and the feeding box are connected through the connection port, the top of the feeding box is also rotatably equipped with a baffle, the baffle is used to open or close the connection port, the bottom of the feeding box is provided with a guide slope, the color matching tank is provided with a stirring assembly, the stirring assembly includes a flap that fits against the baffle and a scraper that fits against the side wall of the color matching tank, the flap and the scraper are rotatably arranged in the color matching tank.

[0007] Furthermore, the stirring assembly also includes a stirring shaft rotatably installed inside the color mixing tank, and the shaft body of the stirring shaft is fixedly provided with a plurality of stirring blades from top to bottom.

[0008] Furthermore, the flap is fixedly installed at the lower end of the stirring shaft, the other end of the flap is fixedly connected to the scraper, and the other end of the scraper is fixedly connected to the stirring shaft through a connecting rod.

[0009] Furthermore, a drive motor is fixedly installed on the top of the color mixing tank, and the output end of the drive motor passes through the top wall of the color mixing tank and is fixedly connected to the stirring shaft.

[0010] Furthermore, the color mixing can is a cylindrical structure with an open bottom, the diameter of the connection port at the top of the feeding box corresponds to the outer diameter of the color mixing can, and the bottom of the color mixing can is installed inside the connection port of the feeding box.

[0011] Furthermore, one side of the baffle is rotatably mounted on the side wall of the feed box.

[0012] Furthermore, an electric push rod is rotatably mounted on the side wall of the feeding box below the baffle, and the other end of the electric push rod is rotatably connected to the baffle.

[0013] Furthermore, the bottom of the feeding box is located at the bottom of the guide slope and has a discharge port that communicates with the feeding box.

[0014] Furthermore, the top of the color mixing tank has a feed inlet that communicates with the inside of the color mixing tank.

[0015] By adopting the above technical solution, this utility model has the following beneficial effects:

[0016] 1. The mixing assembly adopts a triple linkage design of "mixing blade + flap + scraper". The mixing blade is responsible for the main mixing, the flap below is specifically for stirring the stationary material that is easy to accumulate at the bottom of the tank, and the scraper on the side continuously scrapes off the material attached to the inner wall. The three work together to completely eliminate mixing dead corners, ensuring the uniform flow and full mixing of powder in the whole tank, which greatly improves the uniformity and accuracy of color matching.

[0017] 2. The scraper can promptly remove powder coating adhering to the inner wall of the mixing tank, and the flap prevents the material from caking at the bottom, resulting in extremely low material residue in the tank after each mixing. This not only reduces the waste of expensive pigments and lowers production costs, but more importantly, it effectively avoids cross-contamination between different batches and different colors of material, ensuring the purity of the product color;

[0018] 3. The guide ramp and rotatable baffle of the discharge box constitute a highly efficient flow guiding system. During unloading, the baffle rotates downward and abuts against the guide ramp, forming a continuous and unobstructed slide, allowing the material to be smoothly and quickly concentrated at the discharge port by its own weight, which greatly improves the unloading efficiency and further reduces the residue in the unloading process;

[0019] 4. The entire equipment integrates mixing and unloading functions, with a reasonable structural layout. All core operations (mixing and opening / closing unloading) can be completed by a drive motor and electric push rod, requiring no manual intervention. It is easy to operate, has low labor intensity, and is conducive to the automation control of the production process.

[0020] 5. The specially designed mounting groove in the center of the baffle ensures that the stirring shaft will not interfere with the closed baffle when rotating at high speed, thus guaranteeing the stability and safety of the equipment operation and extending the service life of the equipment.

[0027] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0028] like Figure 1-3 As shown in this embodiment, a powder coating color matching device is provided, including a housing 100. The housing 100 includes a cylindrical color matching tank 1 located at the top and a square feeding box 2 located at the bottom. The top of the feeding box 2 is provided with a connection port 21, and the color matching tank 1 and the feeding box 2 are connected through the connection port 21. A baffle 4 is rotatably installed on the top of the feeding box 2. The baffle 4 is used to open or close the connection port 21. The color matching tank 1 is provided with a stirring assembly 3, which is used to stir the material in the color matching tank 1 evenly, thereby improving the color matching effect.

[0029] In this embodiment, the stirring assembly 3 includes a stirring shaft 31 rotatably installed in the color mixing tank 1. A plurality of stirring blades 32 are fixedly arranged on the shaft of the stirring shaft 31 from top to bottom. When the stirring shaft 31 rotates, it drives the stirring blades 32 to rotate synchronously. When the stirring blades 32 rotate, they agitate and stir the material in the color mixing tank 1, thereby completing the color mixing.

[0030] In this embodiment, in order to ensure that the material in the color mixing tank 1 is fully stirred, thereby improving the color mixing efficiency and effect of the powder coating, a flap 33 is fixedly installed at the lower end of the stirring shaft 31. The flap 33 is in contact with the baffle 4 below the color mixing tank 1. When the stirring shaft 31 rotates, it drives the flap 33 to rotate together, so that the flap 33 flips the material accumulated on the baffle 4, thereby making the material fully mixed. At the same time, a scraper 34 is fixedly installed on the other side of the flap 33. The scraper 34 is in contact with the side wall of the color mixing tank 1. The other end of the scraper 34 is fixedly connected to the stirring shaft 31 through a connecting rod 36, so that when the stirring shaft 31 rotates, it drives the scraper 34 to rotate synchronously. The scraper 34 scrapes off the material adhering to the inner wall of the color mixing tank 1, avoiding some material adhering to the inner wall of the color mixing tank 1, which would lead to insufficient mixing of the material, waste, and affect the color mixing effect.

[0031] In this embodiment, a drive motor 35 is fixedly installed on the top of the color mixing tank 1. The output end of the drive motor 35 passes through the top wall of the color mixing tank 1 and is fixedly connected to the stirring shaft 31, so that the drive motor 35 can drive the stirring shaft 31 to rotate inside the color mixing tank 1, thereby driving the stirring blade 32, scraper 34 and flipper 33 to rotate together. When rotating, the stirring blade 32 stirs and mixes the material in the color mixing tank 1, and the flipper 33 turns over the material accumulated at the bottom of the color mixing tank 1, so that the material can be fully mixed by the stirring blade 32, avoiding the material from accumulating at the bottom of the color mixing tank 1 and not being mixed evenly. At the same time, the scraper 34 scrapes off the material attached to the side wall of the color mixing tank 1, avoiding some material from adhering to the inner wall of the color mixing tank 1, which would cause insufficient mixing of the material, waste and affect the color mixing effect, and further improve the color mixing effect.

[0032] In this embodiment, the color mixing tank 1 is a cylindrical structure with an open bottom. The diameter of the connection port 21 at the top of the feeding box 2 corresponds to the outer diameter of the color mixing tank 1. The bottom of the color mixing tank 1 is installed in the connection port 21 of the feeding box 2, thereby making the color mixing tank 1 and the feeding box 2 fixedly connected.

[0033] In this embodiment, one side of the baffle 4 is rotatably mounted on the side wall of the feeding box 2. An electric push rod 22 is rotatably mounted on the side wall of the feeding box 2 below the baffle 4. The other end of the electric push rod 22 is rotatably connected to the baffle 4. The extension or retraction of the electric push rod 22 can drive the baffle 4 to rotate relative to the connection port 21, so that the baffle 4 can close or open the connection port 21. When the baffle 4 closes the connection port 21, the baffle 4 abuts against the upper surface of the feeding box 2, thereby preventing the baffle 4 from moving excessively and failing to completely close the connection port 21.

[0034] In this embodiment, to facilitate material discharge, a guide ramp 24 is provided at the bottom of the feeding box 2. At the bottom of the guide ramp 24, a discharge port 23 connected to the feeding box 2 is provided. When the electric push rod 22 drives the baffle 4 to rotate to open the discharge connection port 21, the movable end of the baffle 4 moves toward the guide ramp 24 until it abuts against the guide ramp 24 below the feeding box 2. At this time, the baffle 4 forms a guide plate. The material falls from the connection port 21 into the feeding box 2, is guided by the baffle 4, and continues to fall along the guide ramp 24 below the feeding box 2, and is discharged through the discharge port 23.

[0035] In this embodiment, the center of the baffle 4 is provided with an installation groove 41 corresponding to the rotating shaft, which ensures that the stirring shaft 31 will not interfere with the baffle 4 in the closed state when rotating at high speed, thus ensuring the stability and safety of the equipment operation and extending the service life of the equipment.

[0036] In this embodiment, the top of the color mixing tank 1 is provided with a feed port 11 that communicates with the inside of the color mixing tank 1.

[0037] The working process and principle of this utility model are as follows: The electric push rod 22 drives the baffle 4 to move, so that the baffle 4 seals the connection port 21, and a certain proportion of powder coatings of various colors are put into the color mixing tank 1 through the feed port 11; the drive motor 35 drives the stirring shaft 31 to rotate in the color mixing tank 1, which in turn drives the stirring blade 32, scraper 34 and flip plate 33 to rotate together. When rotating, the stirring blade 32 stirs and mixes the materials in the color mixing tank 1, and the flip plate 33 turns over the materials accumulated at the bottom of the color mixing tank 1, so that the materials can be fully mixed by the stirring blade 32, and avoids the materials accumulating at the bottom of the color mixing tank 1 and not being mixed evenly. While ensuring even mixing, the scraper 34 scrapes off the material adhering to the side wall of the color mixing tank 1, preventing some material from adhering to the inner wall of the color mixing tank 1, which would lead to insufficient mixing of the material, waste, and affect the color mixing effect, thus further improving the color mixing effect. After the color mixing is completed, the electric push rod 22 drives the baffle 4 to rotate to open the connection port 21. The movable end of the baffle 4 moves towards the guide slope 24 until it abuts against the guide slope 24 at the bottom of the feeding box 2. At this time, the color-mixed material falls from the connection port 21 into the feeding box 2, and then continues to fall along the guide slope 24 below the feeding box 2, and is discharged through the discharge port 23.

[0038] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model. 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.
