Description

Technical Field

[0001] This utility model relates to the field of reflective material coating technology, specifically a coating device for reflective materials. Background Technology

[0002] Coating is a method of producing composite materials by applying a paste-like polymer, molten polymer, or polymer melt onto paper, cloth, or plastic film. Reflective materials are mainly used to make various reflective signs, safety facilities, etc. The bright reflective effect can effectively enhance human visibility, prevent accidents, and reduce economic losses.

[0003] Traditional coating involves mixing a high-refractive-index binder and then applying it. However, the mixed material contains a large number of air bubbles, which cause wrinkles on the coated surface, disrupting the refractive interface and affecting the reflective effect. Traditional reflective materials require multiple coatings, which reduces coating efficiency and easily leads to material waste. Utility Model Content

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention introduces material into the defoaming cylinder through a feed pipe. A motor drives a worm gear and a rotating drum to rotate, expelling air bubbles from the material through centrifugal force. Simultaneously, the rotating drum drives a drive gear, which in turn drives a driven gear and a stirring rod. The rotation of the stirring rod further ensures uniform mixing of the material. Combined with a filter plate, this enhances the defoaming effect and ensures coating quality.

[0013] This invention also features three parallel storage bins with independently connected feed pipes. The bottom micro-concave roller independently coats the adhesive, reflective microbeads, and surface protective layer. The micro-concave roller effectively avoids adhesive residue and wrinkles. The rotation of the micro-concave roller during coating effectively prevents the reflective microbeads from being squeezed and broken. The electric slide rail and telescopic rod allow the position of the micro-concave roller to be adjusted, effectively enhancing the actual coating effect of the micro-concave roller.

[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 1-4 This utility model provides a technical solution: a coating device for reflective materials, including a base 1. A conveyor belt is provided on the upper surface of the base 1 for conveying items. The conveyor belt can also be replaced with a guide roller, which is used to coat the fabric. The upper surface of the base 1 is fixedly connected to a slide rail 2. A slider 3 has a groove on its bottom surface, and the slider 3 slides in contact with the surface of the slide rail 2 through the groove. The slide rail 2 is electrically connected to a controller via a wire. The slide rail 2 causes the slider 3 to drive a micro-concave roller 6 to move horizontally, thereby adjusting the position of the micro-concave roller 6.

[0021] A storage tank 5 is installed above the base 1, with the storage tanks 5 arranged side by side. The top of each storage tank 5 is rotatably connected to the outside of the rotating drum 10 via a bearing sleeve. The bottom end of the rotating drum 10 extends into the storage tank 5 and is fixedly connected to the defoaming cylinder 15. Several filter holes are opened on the outside of the defoaming cylinder 15. The bottom surface of the defoaming cylinder 15 is fixedly connected to the connecting shaft 16, and the bottom end of the connecting shaft 16 is fixedly connected to the drive gear 17. A spiral stirring blade is provided on the outside of the stirring rod 18, and the outside of the stirring rod 18 is fixedly connected to the driven gear 19. The driven gear 19 meshes with the drive gear 17. Both ends of the stirring rod 18 are rotatably connected to the inside of the storage tank 5. The spiral blades on the outside of the stirring rod 18 stir and mix the material inside the storage tank 5, which, together with the filter plate 20, filters the material and promotes defoaming.

[0022] A motor 12 is fixedly mounted on the upper surface of the storage bin 5. One end of the motor 12 is connected and fixed to the worm gear 13, and the outer side of the motor 12 is meshed with the worm wheel 11.

[0023] The storage bin 5 is fixedly connected to the guide rail 7 on one side and to the side plate 8 on one side. The storage bin 5 is rotatably connected to the outer side of the rotating drum 10, which is fixedly connected to the worm gear 11 on the outer side. The rotating drum 10 is rotatably connected to one end of the feed pipe 14. The bottom of the rotating drum 10 is fixedly connected to the deaerator 15, and a drive gear 17 is fixedly connected to the bottom of the deaerator 15. A stirring rod 18 is installed inside the storage bin 5, and the storage bin 5 is fixedly connected to the filter plate 20. The motor 12 drives the worm gear 13 to rotate the rotating drum 10 and the worm gear 11, which in turn drives the deaerator 15 to rotate. The centrifugal force generated by the rotation of the deaerator 15 removes air bubbles from the material. The deaerator 15 then drives the drive gear 17 to rotate via the connecting shaft 16. The drive gear 17 causes the stirring rod 18 and the driven gear 19 to rotate, further promoting mixing and removing air bubbles through the driven gear 19's stirring.

[0024] The slider 3 is connected and fixed to the storage box 5 via the bracket 4. The upper surface of the slider 3 is fixedly connected to the bracket 4. A telescopic rod 9 is fixedly installed on the bracket 4. The output end of the telescopic rod 9 is fixedly connected to the side plate 8. A dovetail groove is formed on the upper surface of the bracket 4. The bracket 4 slides with the outer side of the guide rail 7 through the dovetail groove. The slider 3 is connected to the storage box 5 via the bracket 4. A micro-concave roller 6 is set at the bottom of the storage box 5. The telescopic rod 9 allows the storage box 5 and the side plate 8 to move up and down, thereby adjusting the height of the micro-concave roller 6. The dovetail groove and the guide rail 7 cooperate to allow the guide rail 7 to move up and down in a balanced manner on both sides.

[0025] Working principle: During use, the coated item is placed on the conveyor belt on the upper surface of the base 1. The position of the micro-concave roller 6 is adjusted by the sliding of the slider 3 on the outside of the slide rail 2. The height of the micro-concave roller 6 is adjusted by the telescopic rod 9 causing the side plate 8 to move up and down the storage box 5. The twin-screw extruder and gear pump work together to allow three different materials to be fed into the defoaming cylinder 15 separately through the feed pipe 14. The motor 12 causes the worm gear 13 to drive the rotating drum 10 and worm wheel 11 to rotate. The rotating drum 10 drives the defoaming cylinder 15 to rotate. The centrifugal force generated by the rotation of the defoaming cylinder 15 removes air bubbles from the material. Then, the defoaming cylinder 15 drives the drive gear 17 to rotate through the connecting shaft 16. The drive gear 17 drives the stirring rod 18 and the driven gear 19 to rotate. The driven gear 19 stirs the material to further promote mixing and remove air bubbles. The adhesive, reflective microspheres and surface protective layer are coated sequentially by the micro-concave rollers 6 distributed in series, improving coating efficiency.
