[0034] like Figure 1 As shown, in the embodiment of the present application, the strip galvanizing equipment includes:

[0035] A pay-off frame 100, wherein the pay-off frame 100 is used to place the rod coil;

[0036] A butt welding machine 110, which is used to weld the ends of the galvanized rods on two successive rod coils;

[0037] A dephosphorization machine 120, which is used to remove the phosphate layer on the surface of the galvanized strip;

[0038] A steel brush machine 130, the steel brush machine 130 is used to remove rust on the surface of the galvanized pull rod;

[0039] At least one belt sander 140, the belt sander 140 is used to sand the surface of the galvanized strip;

[0040] A driving host 150, wherein the driving host 150 is used to drive the transmission of the galvanized pull rod;

[0041] A heating machine 180, the heating machine 180 is used to heat the galvanized rod;

[0042] A galvanizing component 190, wherein the galvanizing component 190 is used to galvanize the galvanized pull rod;

[0043] An air ring 200, which is used to blow away the zinc liquid on the surface of the galvanized rod;

[0044] A water cooling box 210, wherein the water cooling box 210 is used to cool the galvanized pull rods;

[0045] The cutting machine 230 is used to cut the galvanized rods into preset sizes.

[0046] like Figure 1 As shown, in the embodiment of the present application, the pay-off frame is used to place the tension rod roll. After the tension rod roll is placed on the pay-off frame, it can be rotated along its axis to release the tension rod wound thereon. Figure 1 The dotted line in the figure is the transmission path of the galvanized rod after being released from the rod roll, and the arrow indicates the transmission direction. After being released from the pay-off frame, the galvanized rod enters the butt welding machine 110, and the butt welding machine 110 can weld the head and tail of the two rod rolls. For example, the tail of the rod on the first rod roll is welded to the head of the rod on the second rod roll, the tail of the rod on the second rod roll is welded to the head of the rod on the third rod roll, and so on.

[0047] After the galvanized rods on each rod roll are welded end to end, they can continuously pass through various galvanizing links under the drive of the driving host 150. For example, in the embodiment of the present application, along the traveling direction of the rods, they pass through the dephosphorization machine 120, steel brush machine 130, belt grinder 140, driving host 150, heating machine 180, galvanizing assembly 190, air ring 200, water cooling box 210 and cutting machine 230 in sequence.

[0048] Specifically, after the ends of the galvanized rods on two coils are welded by the butt welding machine 110, they can continuously enter the dephosphorization machine 120. The dephosphorization machine 120 can peel the galvanized rods to remove the phosphating layer on the surface to avoid affecting the tin plating.

[0049] After passing through the dephosphorization machine 120, the galvanized pull rods successively enter the steel brush machine 130, which can remove the rust on the surface of the galvanized pull rods.

[0050] After the galvanized strip passes through the steel brush machine 130, it enters the belt grinder 140, which uses the sanding belt to finely grind the galvanized strip. In order to ensure the fine grinding effect of the surface of the galvanized strip, multiple belt grinders 140 can also be set. Figure 1 As shown, in the embodiment of the present application, a first grinder 141, a second grinder 142 and a third grinder 143 are respectively provided, that is, the galvanized pull rod can be successively polished by three grinders, and the three polishings can ensure that the surface of the galvanized pull rod has a high degree of smoothness, which is convenient for subsequent tinning. In addition, it should be noted that in the embodiment of the present application, three belt grinders 140 are provided, and in other embodiments, two, four or more belt grinders 140 can also be provided, and the technical solution of the present application does not limit the specific number of belt grinders 140.

[0051] After the galvanized rod is finely ground by the belt grinder 140, it enters the heating machine 180 through the driving host 150, wherein the heating machine 180 can be a high-frequency heating machine. After the galvanized rod is high-frequency heated, it can be preheated to a temperature substantially the same as the zinc liquid temperature during galvanizing. In the embodiment of the present application, the preheating temperature of the high-frequency heating machine 180 can be set at 440-500° C. After the galvanized rod is preheated to a temperature substantially the same as the zinc liquid temperature during galvanizing, galvanizing can have a better galvanizing effect.

[0052] In an embodiment of the present application, the galvanizing component 190 includes a zinc pot, a galvanizing tank and a circulation pump, wherein the zinc pot is used to heat the zinc liquid, the circulation pump connects the zinc pot and the galvanizing tank, the circulation pump is used to drive the zinc liquid to circulate between the zinc pot and the galvanizing tank, and the galvanizing tank is used to galvanize the pull rod to be galvanized.

[0053] Initially, a zinc block is placed in the zinc pot, and the zinc pot heats the zinc block to convert it into zinc liquid, and heats it to the galvanizing temperature. The circulating pump drives the zinc liquid in the zinc pot to the galvanizing tank, and the preheated galvanized pull rod enters the galvanizing tank for galvanizing. During the galvanizing process, the circulating pump circulates the zinc liquid in the zinc pot and the galvanizing tank, thereby ensuring that the temperature of the zinc liquid in the galvanizing tank is always maintained at the preset temperature, ensuring that the pull rod can be galvanized smoothly. In addition, when the zinc liquid in the galvanizing tank is galvanizing, impurities on the pull rod may fall off in the galvanizing tank. Two devices for holding zinc liquid, the zinc pot and the galvanizing tank, are set up. A filtering device, such as a filter net, can be installed on the circulating pump, so that the impurities that fall off the pull rod when the zinc liquid is circulated will be filtered out, so that they always stay in the galvanizing tank, avoiding impurities from entering the zinc pot. After the zinc liquid cools, the impurities are wrapped in the zinc block, ensuring that the zinc pot is not contaminated.

[0054] When the galvanized rod passes through the galvanizing tank, the zinc liquid can adhere to the surface of the rod. After the rod leaves the galvanizing tank, in addition to forming a galvanized layer, its surface will also absorb the zinc liquid. Therefore, after the rod leaves the galvanizing tank, it enters the air ring 200, and the air ring 200 can blow out an annular gas. The annular gas blown out by the air ring 200 can clean the zinc liquid on the surface of the rod. In addition, in the embodiment of the present application, the gas blown out by the air ring 200 can be nitrogen. Nitrogen has high chemical stability and will not produce a chemical reaction after contacting with the high-temperature zinc liquid on the surface of the rod.

[0055] The galvanized rods pass through the air ring 200 and enter the water cooling box 210, which can cool the galvanized rods.

[0056] After the galvanized rod is cooled by the water cooling box 210, it enters the cutting machine 230 for cutting. In the embodiment of the present application, the cutting machine 230 can be a liquid cutting machine, which has a better cutting effect. The cutting machine 230 can cut the galvanized rod as needed. For example, if the rod needs to be placed in a roll after galvanizing, it can be cut according to the length of each roll; or, after galvanizing, it can be directly cut into the length of the rod installed on the photovoltaic device.

[0057] By setting up a butt welding machine 110, the embodiment of the present application can weld the ends of the galvanized rods on two consecutive rod rolls, so that the rod head only needs to be installed once, and continuous galvanizing can be carried out subsequently; by setting up a cutting machine 230, the galvanized rods can be cut into required lengths according to subsequent needs after the galvanizing is completed; in addition, by setting up a dephosphorization machine 120, a steel brush machine 130 and a belt grinder 140, it can be ensured that the surface of the galvanized rod has a higher degree of smoothness, so that it has a higher appearance quality after galvanizing.

[0058] like Figure 1As shown, in the embodiment of the present application, the galvanizing equipment further includes a four-roller sizing machine 160, which is disposed between the driving host 150 and the heating machine 180, and is used to size the galvanized rod according to a preset size. The four-roller sizing machine 160 is used to size the rod before galvanizing the rod, so as to avoid damage to the zinc layer on the surface of the rod caused by sizing after galvanizing.

[0059] like Figure 1 As shown, in the embodiment of the present application, the galvanizing equipment further includes a six-roller shaping machine 170, which is arranged between the four-roller sizing machine 160 and the heating machine 180, and the six-roller shaping machine 170 is used to straighten the galvanized rod. In the embodiment of the present application, the rod is straightened after sizing, so that the galvanized rod can be galvanized in the straightened form, which can improve the galvanizing quality of the rod surface.

[0060] like Figure 1 As shown, in the embodiment of the present application, the galvanizing equipment further includes a straightening machine 220, which is arranged between the water cooling box 210 and the cutting machine 230, and is used to straighten the cooled rods. In the embodiment of the present application, the rods are cooled by the water cooling box 210 after tinning, and the internal stress of the rods is released after cooling, and they are easy to deform. Therefore, the straightening machine 220 is arranged after the water cooling box 210 to straighten the cooled rods to ensure that the rods have a straight shape.

[0061] like Figure 1 As shown, in the embodiment of the present application, the galvanizing equipment further includes a passivation tank 230, which is provided between the straightening machine 220 and the cutting machine 230, and is used to passivate the surface of the galvanized pull rod. The passivation tank 230 is provided to passivate the surface of the pull rod after tinning to reduce the chemical activity of the pull rod surface and make it have higher anti-corrosion performance.

[0062] like Figure 1 As shown, in the embodiment of the present application, the driving host 150 is further provided with a speed regulating module, and the speed regulating module is used to adjust the driving speed of the driving host 150. In the embodiment of the present application, the driving host 150 can be a transmission device driven by a motor to drive the pull rod to move, and the speed regulating module can be a transmission, which controls the driving speed of the motor, thereby changing the travel speed of the pull rod, so that the user can adjust the travel speed of the pull rod according to the actual galvanizing situation.

[0063] like Figure 1As shown, in the embodiment of the present application, the galvanizing assembly 190 further includes a zinc liquid temperature detection module, which is arranged in the zinc pot, and is used to detect the temperature of the zinc liquid in the zinc pot. The zinc liquid temperature detection module is arranged in the zinc pot to detect the temperature of the zinc liquid in the zinc pot in real time, so as to facilitate the regulation of the temperature of the zinc liquid in the zinc pot according to the real-time detection value.

[0064] By setting up a butt welding machine 110, the embodiment of the present application can weld the ends of the galvanized rods on two consecutive rod rolls, so that the rod head only needs to be installed once, and continuous galvanizing can be carried out subsequently; by setting up a cutting machine 230, the galvanized rods can be cut into required lengths according to subsequent needs after the galvanizing is completed; in addition, by setting up a dephosphorization machine 120, a steel brush machine 130 and a belt grinder 140, it can be ensured that the surface of the galvanized rod has a higher degree of smoothness, so that it has a higher appearance quality after galvanizing.
