Description

Technical Field

[0001] The utility model relates to the technical field of oil pastel forming machines, in particular to an oil pastel forming machine. Background Art

[0002] Oil sticks are an oil-based color painting tool, generally cylindrical or prismatic with a length of about 10 cm. Similar in appearance to crayons, but with stronger adhesion and covering power on paper, they can produce oil painting-like effects. Oil sticks have a delicate, smooth feel, good spreadability, and excellent color stacking and mixing performance. The most prominent ultra-fine thickened coating material makes the coating more textured, with a coating weight of 0.002g / cm2. They can fully display the effect of oil painting and meet the difficulty requirements of various painting techniques. Ultra-low temperature ammonia freezing makes the pressure density greater and the molecular structure of the stick more compact, with a single weight of about 8.5g. The anti-fracture force is not less than 4N, and it is less likely to break or wear out. Oil sticks look like crayons, but they are not actually crayons. Compared with crayons, oil sticks have brighter colors, stronger adhesion and covering power on paper, and are one of the favorite painting tools for children.

[0003] A Chinese patent disclosed a fully automatic oil pastel molding machine with a publication number of CN208558354U, and the application date is 2018.06.26. The patented technology is controlled in real time through a control panel, and there will be no over-temperature or under-temperature situation, which ensures the normal operation of the work and improves the safety of the work. The device is internally equipped with a stirring shaft. After the paraffin is melted, the stirring shaft can continuously stir the melted paraffin, thereby effectively ensuring the fluidity of the paraffin, which is beneficial to the subsequent molding work. The device is also equipped with a refrigerator in the molding chamber. During the molding operation, the refrigerator can quickly reduce the temperature of the molding machine, so that the paraffin can be quickly cooled and molded, which greatly improves the work efficiency, and the molding mold of the device is installed at the output end of the motor. During the molding process, the mold can rotate continuously, so that the paraffin filled in the mold is uniform, ensuring the effect of paraffin molding. However, in the paraffin heating process of the above patent, since the heating device is arranged at the bottom of the wax melting chamber, the paraffin is heated slowly. Although there is a stirring mechanism to stir the paraffin, the stirring effect of the stirring mechanism is poor in the initial stage of heating, resulting in a long melting time of the paraffin, which affects the efficiency. Therefore, the inventor provides an oil pastel molding machine to solve the problems raised in the above background technology. Utility Model Content
