Plastic spraying, especially the coating of 3C shell and fittings, requires high productivity and high quality in most cases. The dust-free level of spraying is in the range of 1000-10000. Because of the high production capacity of the wire body and the Fast linear speed, the consumption of paint is also quite large, how to save the cost of raw materials has become a consensus. In order to save paint to a greater extent, our company has developed a point spraying system: wire body into the spraying The light is transmitted to the spraying system, after receiving signals, start to transport paint spraying, if there is no, the following is, is is necessary to provide paint and spraying, Thus avoiding the waste of paint.
On the other hand, most of the plastic automatic spraying lines require that the qualified rate of customers’products reach more than 95%. In view of this problem, our company has developed a stable conveying system and a perfect 10,000-grade dust-free Air supply system together with customers after accumulating and summarizing the experience of many production lines, so as to maximize the qualified rate. The automatic line conveyor chain is made of aluminium alloy machine and knurled, with a bearing in the middle position. The fixture is assembled on the automatic conveyor chain, the bearing is clamped by the side rail on both sides of the bearing position to prevent the shaking of the products and the two sides of the chain, especially for large products and heavy products, this side rail The 10,000-grade air supply system is developed by our company, which includes quick-disassembly air supply cabinet, all-aluminium alloy cabinet, bolt link, The internal oversight system is the primary, medium and sub-high efficiency filter, and the patio filter is the high efficiency filter. Thus, the overall effect can not achieve 1000-level effect in The whole filter system can be disassembled and fast disassembled. Easy to replace the filter system.
There are many spraying methods for automatic plastic parts: fixed gun automatic spraying, reciprocating tracking spraying, robot spraying, etc. Among them, the requirement of robot spraying is that the line speed should not be too fast, 1-3 m/min is More appropriate, too fast, the robot can not keep up with, after all, the spraying efficiency is limited. Fixed gun automatic spraying for paint waste is more, efficient, line speed can reach about 15 meters per minute. Reciprocating payback tracking can be In particular cases, we choose suitable spraying methods according to customer productivity requirements and product complexity. One group of tracking is not enough. We add another group of spraying systems. Tracking spraying is more flexible than fixed Gun. Production efficiency is guaranteed, and product quality is guaranteed.
The product drying forms are also diversified: medium wave infrared heating tube, far infrared radiation heating, natural gas heating, steam heating, heat pump heating, etc. In order to keep the temperature curve smooth and stable, if necessary, the furnace can be The automatic line drying oven is equipped with an overhaul door every other section. The overhaul door should be set in opposite and dislocation, which can be made into a full open door for easy overhaul.
