Embodiment 1
[0021] Such as figure 1 As shown, a four-station spraying system includes a conveying channel 1, on which a first spray booth 2 and a second spray booth 3 are arranged sequentially from right to left; the first spray booth 2 is provided with I station 4 and II station 5, III station 6 and IV station 7 are set in the second spray booth 3; a drying tunnel 8 is set on the far left side of the conveying channel 1; it is set between II station 5 and III station 6 A 30s leveling zone9.
Embodiment 2
[0023] Utilize the process of spraying steel drums with the four-station spraying system, the steps are as follows:
[0024] (1) The first spraying: the single-color steel drum is directly sprayed completely on the I station 4, and then continues to be conveyed through the conveying channel 1;
[0025] (2) Pre-trimming: the single-color steel drum is directly conveyed through the Ⅱ station 5 and continues to be conveyed through the conveying lane 1;
[0026] (3) Leveling: Set a 30s leveling zone 9 between the II station 5 and the III station 6, so that the wet paint film on the sprayed steel drum can fully flow, thereby eliminating the paint marks and making the paint film surface reach Uniform and smooth, the solvent is fully volatilized in the leveling zone 9, which ensures the quality of the secondary trimming, and then continues to be conveyed through the conveying channel 1;
[0027] (4) The second spraying: the single-color steel drum passing through the leveling zone 9...
Embodiment 3
[0032] Utilize the process of spraying steel drums with the four-station spraying system, the steps are as follows:
[0033] (1) The first spraying: the two-color steel drum is only sprayed with the white acrylic baking varnish in the middle of the barrel body, and the bottom cover is sprayed with China Resources Lan amino baking varnish, and then continues to be conveyed through the conveyor 1;
[0034] (2) Pre-trimming: Take the two-color steel drum sprayed for the first time, and use China Resources Lan amino baking paint on the two-color steel drum at the second station to pre-cut the paint on the ring ribs where the two different colors intersect, and then Continuing to transmit through the transmission lane 1;
[0035] (3) Leveling: Set a 30s leveling zone 9 between the II station 5 and the III station 6, so that the wet paint film on the sprayed steel drum can fully flow, thereby eliminating the paint marks and making the paint film surface reach Uniform and smooth, th...
