Technical Field

[0001] This utility model relates to the field of molded tableware production technology, and in particular to a surface coating device for pulp molded tableware. Background Technology

[0002] Molded pulp tableware is a biodegradable and environmentally friendly type of tableware made from plant fibers (such as bagasse and reed pulp) through molding and drying processes. After a period of time in soil or water, molded pulp tableware decomposes into carbon dioxide and water under the action of microorganisms, without causing long-term environmental pollution. Compared to traditional plastic tableware, it is significantly more environmentally friendly and helps reduce plastic pollution.

[0003] Existing molded pulp tableware requires multiple steps in production, and the following problems still exist during the surface coating process:

[0004] 1. In the existing technology, when coating the surface of molded pulp tableware, most of the coatings are applied manually, resulting in low surface smoothness and poor effect;

[0005] 2. Existing equipment for coating the surface of molded pulp tableware provides better smoothness than manual brushing, but the molded pulp tableware cannot cool and solidify quickly after coating, resulting in reduced work efficiency. Utility Model Content

[0028] The conveying device 8 includes two rotating shafts 81, located at both ends of the frame 1. A support shaft is provided on the frame 1 between the two rotating shafts 81. The support shaft is located directly below the first mounting frame 2 and the second mounting frame 3. A conveyor belt 82 is connected between the two rotating shafts 81. The rotating shafts 81 are rotatably connected to the frame 1, and driven wheels 83 are fixedly connected to both ends. A drive motor 85 is fixedly connected to the rear frame 1. A drive wheel 86 is fixedly connected to the output end of the drive motor 85. A driven chain 84 is meshed between the driven wheels 83 on the front side. An output chain 87 is meshed between the driven wheels 83 and the drive wheel 86 on the rear side. Both the driven wheels 83 and the drive wheel 86 are sprockets of the same type. In use, the drive motor 85 drives one end of the rotating shaft 81 to rotate by driving the driven wheels 83, the drive wheel 86 and the output chain 87. Then, the driven wheels 83 and the driven chain 84 drive the other end of the rotating shaft 81 to rotate, thereby driving the entire conveyor belt 82 to rotate.

[0029] The upper side of the conveyor belt 82 is provided with a receiving mechanism 6. There are several receiving mechanisms 6, which are evenly distributed on the conveyor belt 82. The receiving mechanism 6 includes a base 61. A rubber block 64 is fixedly connected between the lower side of the base 61 and the conveyor belt 82, and a slider 62 is slidably connected to the upper side.

One end of the pipe 71 is located inside the mixing tank 41, and the other end is located inside the first mounting frame 2. A fan-shaped spray head is fixedly connected to the pipe 71 located inside the first mounting frame 2. The spray angle and spray volume of the spray head can be adjusted according to the shape and size of the tableware.

[0031] Working principle: When in use, first start the drive motor 85, which drives the sprocket and chain to rotate, thereby causing the conveyor belt 82 to move the receiving mechanism 6. Then, place the pulp molded tableware on the limiting strip 63 of the receiving mechanism 6 and start the pump body 7. The pump body 7 extracts the polyvinyl alcohol (PVA) aqueous solution through the pipe 71, and then the fan-shaped spray head coats the pulp molded tableware. Under the precise control of the fan-shaped spray head and the flow meter, the coating material can be evenly distributed on the surface of the tableware, improving the appearance quality and protective performance of the product.

[0032] After coating is completed, the material is moved to the bottom of the dryer 5 by the conveyor belt 82. At this time, the surface temperature of the material is reduced by the dryer 5, thereby increasing the viscosity between the polyvinyl alcohol (PVA) aqueous solution and the pulp molded tableware, achieving rapid coating and improving work efficiency.
