Problems solved by technology
like Figure 7 As shown, it is a conventional galvanized coating production line, which includes pretreatment 1', fluxing 2', preheating 3', zinc bath 4', cooling 5' and passivation 6' and other processes, it is composed of Suspended crane 10' (or manual electric hoist) hangs workpieces (such as steel bars) to run. Because of the use of electric hoist manual hanging or hanging conveyor hanging in this conventional production line, the length of the electroplated workpiece is limited, and in order to electroplate large The workpiece and the depth of the electroplating pool are required to be relatively deep, which makes the volume of the equipment relatively large and the production efficiency low

Embodiment Construction
[0020] Such as figure 1 As shown, the present invention is a galvanized coating production line, which includes a sandblasting machine 1, a plating aid machine 2, a first air knife 3, a preheater 4, a hot dipping tank 5, a second Air knife 6, cooling chamber 7.
[0021] The described fluxing machine 2, the first air knife 3, the preheater 4, the hot dip tank 5, and the second air knife 6 are all provided with moving passages for workpieces to pass through. Between the sandblasting machine 1 and the fluxing machine 2, between the first air knife 3 and the preheater 4, between the preheater 4 and the hot dip pool 5, between the second air knife 6 and the cooling chamber 7 A rolling roller table 8 for running workpieces is arranged between them.
[0022] Such as figure 2 Shown, described helper plating machine 2 comprises upper and lower two rows of helper heads, that is, upper row helper head 21 and lower row helper head 22, the upper row helper head 21 and lower row helper...

The invention discloses a zinc plating coating production line. According to the technical process, the zinc plating coating production line sequentially comprises a sand blaster, an auxiliary plating machine, a first air knife, a preheater, a hot dipping tank, a second air knife and a cooling chamber. The auxiliary plating machine, first air knife, preheater, hot dipping tank and second air knife are respectively provided with a motion channel through which workpieces can pass; and a rolling-type roller way for operating the workpieces is arranged between every two devices. Since the auxiliary plating machine, first air knife, preheater, hot dipping tank and second air knife are respectively provided with the motion channel through which workpieces can pass, steel bars can horizontally pass through different devices one by one according to the procedure. The zinc plating coating production line has the advantages of high production efficiency, high electroplated steel bar length, compact structure and high modularization degree, can increase or reduce the devices according to the spray coating demands, and is easy for expansion and improvement.
Description
technical field [0001] The invention relates to a production line, in particular to a galvanized coating production line. Background technique [0002] Spraying production line refers to a production line that covers metal and non-metal surfaces with protective or decorative layers. The quality of spraying not only determines the appearance of the product, but also determines the corrosion resistance and weather resistance of the product. With the development of industrial technology, the spraying line is developing from manual to industrial automation, and the application of coating line is becoming more and more extensive, and has penetrated into many fields of the national economy. Such as Figure 7 As shown, it is a conventional galvanized coating production line, which includes pretreatment 1', fluxing 2', preheating 3', zinc bath 4', cooling 5' and passivation 6' and other processes, it is composed of Suspended crane 10' (or manual electric hoist) hangs workpieces (s...
