Problems solved by technology

In the actual operation process, the surface layer of the paint film of the workpiece has been air-dried before being put into the UV dryer. When the conveyor belt is close to the UV lighting system, due to the high temperature of the UV lighting system, the workpiece is dried A certain degree of dryness, when the workpiece is illuminated by UV light, since the surface of the workpiece has formed a cured surface layer of the paint film, if the UV light intensity is too low, the UV light cannot penetrate the surface layer of the paint film, and the inner layer of paint will be damaged. The curing is not complete. If the light intensity is too high, the cured surface layer of the paint film will be further cured, and the curing speed will be faster than that of the inner layer paint. The combined stress and strain of the cured paint film surface layer will increase. Some monomers or prepolymers in the inner paint that are too late to react remain in the paint film, resulting in steric hindrance, reducing the integrity and durability of the paint film, making it difficult to achieve a balanced UV light intensity to cure the paint film of the processed parts. It will affect the curing effect of the paint film; and when the existing UV dryer is discharging, the worker must hold the workpiece by hand until it comes out of the discharge port, which is not convenient

Abstract

The invention discloses a novel UV drying machine facilitating discharging. The novel UV drying machine comprises a rack, a driving device, a transmission carrier roller set, a conveying belt driven by the transmission carrier roller set, a machined piece feeding port and a machined piece discharging port are formed on the rack, UV lighting systems are arranged above the conveying belt, the number of the UV lighting systems is at least two, the UV lighting systems are distributed in the moving direction of machined pieces, cooling systems are arranged between the machined piece feeding port in the rack and the UV lighting systems and between the adjacent UV lighting systems respectively, and a discharging slope is arranged at the machined piece discharging port. By means of the technical scheme, the effect of paint film UV solidification is greatly improved, durability is improved, the maintaining cost is lowered, discharging and loading of the machined workpieces are facilitated, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of drying equipment for painting workpieces, and relates to equipment for a painting production line, in particular to a novel UV drying machine which is convenient for discharging. Background technique [0002] UV dryer, that is, ultraviolet light curing dryer is a device for drying workpieces after painting. The prior art UV drying machine includes a frame on which a driving device, a transmission idler group, a conveyor belt driven by the transmission idler group, a workpiece inlet and a workpiece outlet are arranged, and the top of the conveyor belt Equipped with a UV lighting system, the purpose of drying is achieved by moving the workpiece under the UV lighting system. The curing degree and quality of the paint film are largely related to temperature, UV light intensity and light time. In the actual operation process, the surface layer of the paint film of the workpiece has been air-dried before bein...
