Description

Technical Field

[0001] The invention relates to the technical field of spraying equipment, and in particular to an automatic spraying device. Background Art

[0002] In industrial production, manufacturing and many related fields, surface spraying and subsequent drying of objects are extremely common and crucial production processes. However, the traditional surface spraying and drying operation methods have many difficult-to-overcome problems in practical applications, which seriously restrict production efficiency and product quality. First, in terms of operation methods, most traditional operations rely on manual work. This manual operation mode brings a series of disadvantages. On the one hand, manual operation leads to high labor intensity, and operators need to repeat the same actions for a long time, which is easy to cause fatigue, thus affecting work efficiency and making it difficult to meet the rapid needs of large-scale production. On the other hand, due to the instability and subjectivity of manual operation, it is difficult to ensure the uniformity and consistency of spraying quality. During the spraying process, problems such as uneven spraying thickness and local leakage are prone to occur, which will have a serious adverse effect on the overall quality and appearance of the product, such as uneven color on the surface of the product, reduced protective performance, etc., reducing the market competitiveness of the product. Second, from the perspective of equipment layout, the layout design of traditional equipment has obvious defects. The unreasonable layout makes the connection between the spraying and drying processes not smooth enough. When the product is transferred from the spraying process to the drying process, a long waiting time will be generated, which not only increases the time cost of process conversion, but also requires additional logistics equipment for product transportation, thereby increasing logistics costs. This unsmooth connection method greatly affects the continuity of the entire production process, reduces the overall efficiency of production, and is not conducive to the efficient operation of production. Third, there are also deficiencies in the paint supply system. The traditional paint supply system is not flexible enough during the paint delivery process, especially the paint delivery pipeline, which is prone to entanglement and knotting during use. This will not only interfere with the normal delivery of the paint, making the paint supply unstable, and then causing the spraying operation to be unable to proceed stably, but also frequent pipeline problems will affect the normal use time of the equipment, increasing the maintenance cost and repair time of the equipment. Finally, for the problem of all-round processing of objects, traditional equipment lacks an efficient rotation mechanism. When it is necessary to perform all-round spraying and drying operations on objects, due to the lack of an effective rotation mechanism, it is impossible to ensure that the objects can be rotated stably and at multiple angles during movement. This makes it difficult for the surface of the object to be evenly sprayed and dried, which will greatly reduce the performance and appearance of the product. For example, on some products that require precision protective coatings, the protective performance may be affected by uneven coatings, or on products with high requirements for appearance, problems such as inconsistent surface color and uneven glossiness may occur, which ultimately affect the comprehensive performance and market recognition of the product. In summary, in order to overcome the many drawbacks of the above-mentioned traditional spraying and drying operations, it is necessary to develop a more efficient, stable and automated equipment to meet the high requirements of modern industrial production for product quality and production efficiency.

During drying, the object after spraying continues to move with the conveying rotating mechanism 3 and enters the front side of the spray drying chamber 2. At this time, it is dried by the dryer 6. In this process, the pinion 313 in the movable seat 1 35 will also contact the rack 2 315, and will also cause the moving object to rotate, thereby meeting the need for drying the objects around after spraying and ensuring uniform drying. Through the above series of operations, the automatic spraying device can realize automatic spraying and drying of the object.
