Description

Technical Field

[0001] The invention relates to the technical field of spraying equipment, in particular to a surface spraying equipment for producing light box cloth with a quantitative spraying function. Background Art

[0002] In modern manufacturing, spraying technology is a key link in achieving surface treatment and coating, and is widely used in automobiles, aviation, electronics, furniture and other industrial fields. With the development of industrial automation and intelligent manufacturing, higher requirements are placed on the accuracy, efficiency and environmental performance of spraying equipment, which has promoted the development of spraying technology towards higher precision control, more optimized process management, and lower energy consumption and material consumption.

[0003] Current spraying equipment usually includes basic stirring, conveying and spraying functions, and can complete basic paint application tasks. In these devices, the stirring of the paint mostly relies on simple mechanical stirring, the position adjustment during the spraying process is mostly manual or semi-automatic, and the temperature control and cleaning and maintenance are also relatively primitive. These methods often cannot meet the needs of high-precision and high-efficiency industrial production.

[0004] With regard to the above-mentioned related technologies, when processing workpieces, traditional spraying equipment often causes uneven spraying due to insufficient leveling capacity of the conveying system, affecting the appearance and quality of the product. The existing stirring mechanism can usually only provide basic stirring functions, and it is difficult to achieve the requirements of high uniformity and high shear force, which may cause component separation or aggregation of the coating before spraying, affecting the final coating effect and imprecise quantitative control. In the precision manufacturing process, quantitative control of the coating is crucial, but the performance of many existing equipment in this regard is still limited, and the spraying amount cannot be accurately controlled, resulting in material waste and quality fluctuations. Existing equipment often lacks an effective temperature control system and cannot keep the coating at the optimal processing temperature, affecting the spraying quality and speed. Therefore, the technicians in this field provide a surface spraying equipment for light box cloth production with quantitative spraying function to solve the above problems. Summary of the invention

This design enables the temperature control box to be directly connected to the conveyed object, and the temperature of the object is directly adjusted through the adsorption temperature control hole, and the object is adsorbed at the same time. The heating pipe is firmly connected to the temperature control box and adopts a serpentine design to increase the contact area with the air in the temperature control box and improve the heat exchange efficiency. The serpentine design also allows more heat to be transmitted and distributed in a limited space.

The shear motor is firmly connected to the lower end of the outer worm and is connected to the transmission rod, thereby driving the inner worm to rotate by rotating the protrusion. At the same time, the rotating protrusion interacts with the worm groove on the transmission rod through a sliding fit, allowing the inner worm to slide axially while transmitting torque, thereby driving the first shear hole and the second shear hole to move relative to each other to achieve shearing action. At the same time, the aperture design allows the shear aperture to gradually increase during the coating advancement process. At the same time, the adjacent outer worms rotate in opposite directions, so that the coating can be stirred up and down, further optimizing the coating refinement, thereby ensuring that it reaches the ideal uniformity and viscosity before entering the spraying mechanism, thereby improving the spraying effect, reducing coating waste, and improving the quality of the final product.
