Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive interior coating processing technology, specifically to a device for processing wear-resistant coatings for automotive interior ambient light covers. Background Technology
[0002] Automotive coatings have undergone significant changes in terms of base materials, topcoat colors, and application. The main difference lies in the base materials, which have evolved from nitrocellulose enamel to amino alkyd enamel, and the primers from self-drying alkyd resin enamel to thermoplastic acrylic resin enamel. Thermosetting acrylic resin enamel and polyamino enamel have seen substantial improvements in stain resistance, thus enhancing the protective performance of the topcoat. Automotive coatings are protective films sprayed onto automobiles, preventing corrosion and contributing to an aesthetically pleasing appearance. The production process requires high-speed mixing of pigments, resins, and solvents to achieve uniform exchange and thorough wetting. However, current environmentally friendly automotive coating processing equipment consists of single-agitator units, resulting in long mixing times and poor mixing effects. Furthermore, existing equipment often mixes single or multiple raw materials simultaneously, making it unsuitable for materials requiring multiple mixing steps. Therefore, we propose a processing device for wear-resistant coatings for automotive interior ambient lighting covers. Utility Model Content
[0003] This invention provides a device for processing wear-resistant coatings for automotive interior ambient light covers, which solves the problems mentioned in the background art.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a processing device for wear-resistant coating on automotive interior ambient light covers, comprising a mixing tank, an inlet connected to the interior of the mixing tank at the top, and an outlet in the middle of the bottom of the mixing tank. A rotatable stirring component for dispersing is installed in the middle of the interior of the mixing tank. The stirring component is hollow in the middle, and a conveying component with both ends extending out of the stirring component and rotatable relative to the stirring component is installed in the middle of the stirring component. The conveying component is used to convey the coating upwards, and the coating falls from the top between the stirring component and the mixing tank for dispersing.
[0005] Optionally, the stirring assembly includes dispersing blades and a central cylinder. The central cylinder is circular and sleeve-shaped. Vertical dispersing blades are fixedly connected to the outer surface of the central cylinder, and horizontal through holes are formed on the dispersing blades.
[0006] Optionally, the conveying assembly includes a spiral conveying plate and a central shaft, the central shaft being vertically located on the center line of the central cylinder, and the spiral conveying plate being fixed spirally to the outer surface of the central shaft.
[0007] Optionally, the top of the central cylinder is fixedly connected to multiple fixed cylinders, and the top of the fixed cylinders are all fixedly connected to an internal gear disc, which is circularly and movably fitted onto the mixing tank.
[0008] Optionally, the top end of the central shaft is circular, passes through the center of the internal gear disk, and is fixedly connected to a first gear. A second gear meshes with the outer side of the first gear, and the second gear meshes with the inner side of the internal gear disk.
[0009] Optionally, the second gear is connected to the mixing tank via a shaft pin, and a drive motor is fixedly connected to the top of the mixing tank. The output shaft of the drive motor is fixed to the center of the top of the first gear, and a valve is installed in the discharge port.
[0010] This utility model has the following beneficial effects:
[0011] 1. This automotive interior ambient light cover wear-resistant coating processing device effectively avoids coating deposition by conveying the coating upwards through the conveying components, and effectively stirs and disperses the coating by the rotation of the dispersing blades, thereby making the coating mixture more uniform and improving the production quality of the coating.
[0012] 2. The wear-resistant coating processing device for automotive interior ambient light covers enables the conveying component and the mixing component to rotate relative to each other through the mutual cooperation of the first gear, the internal gear plate, and the second gear. That is, it can be driven by a single drive source, thereby reducing its energy consumption. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Please see Figures 1 to 5 A wear-resistant coating processing device for automotive interior ambient light covers includes a mixing tank 1. The top of the mixing tank 1 has an inlet 2 connected to the interior of the mixing tank 1, and the bottom of the mixing tank 1 has an outlet in the middle. The coating enters the interior of the mixing tank 1 through the inlet 2 and exits through the outlet. A rotatable stirring component 5 for dispersing is installed in the middle of the interior of the mixing tank 1. The rotation of the stirring component 5 stirs and disperses the coating, resulting in a more uniform mixture. The stirring component 5 is hollow in the middle, and a conveying component 4 with both ends extending out of the stirring component 5 and rotatable relative to it is installed in the middle of the stirring component 5. The conveying component 4 is used to convey the coating upwards. The conveying component 4 can rotate relative to the stirring component 5, continuously conveying the coating from the bottom of the mixing tank 1 upwards, allowing the coating to fall between the mixing tank 1 and the stirring component 5 for dispersing and stirring, and then fall back to the bottom of the mixing tank 1. The coating falls from the top between the stirring component 5 and the mixing tank 1 for dispersing.
[0021] Please see Figures 1 to 5 The mixing component 5 includes a dispersing blade 7 and a central cylinder 8. The central cylinder 8 is a circular sleeve. The outer surface of the central cylinder 8 is fixedly connected to the vertical dispersing blade 7. The dispersing blade 7 has a transverse through hole. Through the through hole, some of the coating can pass through directly, so that the coating can form a staggered layer, thereby making the mixing more uniform.
[0022] Please see Figures 1 to 5 The conveying assembly 4 includes a spiral conveying plate 10 and a central shaft 11. The central shaft 11 is vertically located on the center line of the central cylinder 8, and the spiral conveying plate 10 is fixed in a spiral shape on the outer surface of the central shaft 11. Then, under the rotation of the spiral conveying plate 10, the paint is conveyed upward.
[0023] Please see Figures 1 to 5The top of the central cylinder 8 is fixedly connected to multiple fixed cylinders 9. Driven by the fixed cylinders 9, the central cylinder 8 can rotate. The top of the fixed cylinders 9 is fixedly connected to an internal gear disk 13. Driven by the internal gear disk 13, the fixed cylinders 9 can rotate. The internal gear disk 13 is circularly and movably mounted on the mixing tank 1. The internal gear disk 13 can rotate in a fixed position on the mixing tank 1.
[0024] Please see Figures 1 to 5 The top end of the central shaft 11 is circular and passes through the center of the internal gear disk 13 and is fixedly connected to the first gear 12, thereby enabling the central shaft 11 to rotate relative to the internal gear disk 13. Under the drive of the first gear 12, the central shaft 11 can rotate. The outer side of the first gear 12 is engaged with the second gear 14, which, under the drive of the first gear 12, can rotate. The second gear 14 is engaged with the inner side of the internal gear disk 13, and under the drive of the second gear 14, the internal gear disk 13 can rotate.
[0025] Please see Figures 1 to 5 The second gear 14 is connected to the mixing tank 1 by a shaft pin, so that the second gear 14 can rotate in a fixed position on the mixing tank 1. A drive motor 3 is fixedly connected to the top of the mixing tank 1. The output shaft of the drive motor 3 is fixed to the center of the top of the first gear 12. Under the drive of the output shaft of the drive motor 3, the first gear 12 can rotate. The drive motor 3 is existing technology and will not be described in detail here. A valve 6 is installed in the discharge port.
[0026] In summary, the wear-resistant coating processing device for automotive interior ambient light covers, when in use, injects the coating into the mixing tank 1 through the feed port 2. Then, driven by the output shaft of the drive motor 3, the first gear 12 rotates, which in turn rotates the second gear 14, thereby driving the internal gear disc 13 to rotate. Driven by the internal gear disc 13, the fixed cylinder 9 rotates, which in turn drives the central cylinder 8 to rotate. Driven by the central cylinder 8, the dispersing blades 7 rotate to disperse the coating. Driven by the first gear 12, the central shaft 11 rotates, which in turn drives the spiral conveyor plate 10 to rotate, conveying the coating from the bottom of the interior upwards, and allowing the coating to fall again between the central cylinder 8 and the mixing tank 1.
