The straightening wheels 12 are alternately arranged on the straightening upper frame 13 and the straightening lower frame 14 respectively, and the straightening wheels 12 are of hollow structures. The first rotary joint is arranged on the straightening wheel 12 and is used for introducing high-temperature steam into the straightening wheel 12 and discharging the high-temperature steam. Specifically, the straightening wheel 12 includes a first rotating shaft 121, a first pressing wheel 122 and a first end cap 123, a filling portion is radially extended from the first rotating shaft 121, steam pipelines are axially arranged at two ends of the first rotating shaft 121, a plurality of steam ports communicated with the steam pipelines are circumferentially arranged on the first rotating shaft 121, and the first pressing wheel 122 and the first end cap 123 are arranged on the first rotating shaft 121 and form a closed steam cavity together with the filling portion. High-temperature steam enters from one end of the first rotating shaft 121 through the first rotating joint, enters the steam cavity from the steam port through the steam pipeline, and is discharged from the other end of the first rotating shaft 121. A narrow steam cavity is formed between the first pressing wheel 122 and the filling part, so that the flow rate of steam can be increased, and high-pressure steam with standard temperature is always kept in the steam cavity; meanwhile, the first pressing wheel 122 is heated by steam, so that the heating efficiency is high, and the heating is uniform. The first pressing wheel 122, the first end cap 123 and the first rotating shaft 121 are fixed and sealed by welding.
In the above embodiment, the first adjustment mechanism 17 includes an adjustment screw rotatably provided on the alignment lower frame 14 and threadedly engaged with the alignment upper frame 13. By turning the adjusting screw, the rotary motion is converted into a linear motion straightening the upper carriage 13.

The invention is not limited to the number of straightening wheels 12, which are shown as six straightening wheels 12, but of course more than six straightening wheels 12, for example ten, twelve or even more, may be provided for further straightening of the welding ribbon.
As shown in fig. 5 to 7, the cooling mechanism 2 includes a second rotary joint (not shown), a cooling wheel 21, an upper cooling frame 22, a lower cooling frame 23, a second guide 24, a second spring 25 and a second adjusting mechanism 26, the second guide 24 may be four guide pillars, the four guide pillars are vertically disposed at four corners of the lower cooling frame 23, the upper cooling frame 22 is disposed on the guide pillars, the second spring 25 is sleeved on the guide pillars, the upper cooling frame 22 is supported by the second spring 25, the second adjusting mechanism 26 is disposed on the upper cooling frame 22 and the lower cooling frame 23, and the upper cooling frame 22 is pushed by the second adjusting mechanism 26 to vertically move along a guiding direction of the second guide 24, so as to adjust a distance between the upper cooling frame 22 and the lower cooling frame 23. The cooling wheels 21 are respectively and symmetrically arranged on the cooling upper frame 22 and the cooling lower frame 23, and the cooling wheels 21 are of hollow structures. The second rotary joint is arranged on the cooling wheel 21 and is used for introducing cooling water into the cooling wheel 21 and discharging the cooling water. Specifically, the cooling wheel 21 includes a second rotating shaft 211, a second pressing wheel 212 and a second end cap 213, a filling portion is radially extended from the second rotating shaft 211, cooling water pipelines are axially arranged at two ends of the second rotating shaft 211, a plurality of water passing ports communicating with the cooling water pipelines are circumferentially arranged on the second rotating shaft 211, and the second pressing wheel 212 and the second end cap 213 are arranged on the second rotating shaft 211 and form a closed cooling water cavity with the filling portion. That is, the second rotating shaft 211, the second pressing wheel 212, the second end cap 213, and the filling part form a closed space, and are communicated with the cooling water pipeline only through the water through holes. The cooling water enters from one end of the second rotating shaft 211 through the second rotating joint, enters the cooling water chamber through the water passage hole, and is discharged from the water passage hole at the other end through the cooling water pipeline and the second rotating joint. By forming a narrow channel between second puck 212 and the fill, the flow rate of the cooling water can be increased, thereby taking heat away more quickly. The second pressure wheel 212, the second end cover 213 and the second rotating shaft 211 can be fixed and sealed by welding.
In the above embodiment, the second adjustment mechanism 26 includes an adjustment screw rotatably provided on the cooling lower frame 23 and screw-engaged with the cooling upper frame 22.

In one embodiment, as shown in fig. 5-8, the cooling device further comprises a connecting pipe 3, and the connecting pipe 3 is connected to the water outlet end and the water inlet end of the cooling wheel 21 in sequence. I.e. the cooling water flows through the respective cooling wheel 21. Preferably, the cooling water enters from the water inlet end of the cooling wheel 21 at the outlet end of the cooling mechanism 2 and flows out from the water outlet end of the cooling wheel 21 at the inlet end of the cooling mechanism 2; therefore, the temperature of the tin-plating solder strip is higher at the inlet end of the cooling mechanism 2, and the temperature is lower at the outlet end; make the cooling water of cooler temperature cool off the tin-plating solder strip of exit end, and cool off the tin-plating solder strip of entry end through the cooling water of higher temperature, can make the cooling water utilization ratio higher like this to tin-plating solder strip uniform cooling, the cooling effect is better, avoids quick cooling to cause tin-plating solder strip toughness to reduce, easy fracture. If each cooling wheel 21 is supplied with independent cooling water, the cooling water is wasted; and the cooling water flows from the inlet end to the outlet end of the cooling mechanism 2, the cooling capacity toward the outlet end is reduced. It should be noted that the above-mentioned connecting pipeline is connected with the water inlet end and the water outlet end of the cooling wheel 21 through the second rotary joint.
In the above embodiments, the cooling water is typically normal-temperature tap water; therefore, the phenomenon that the toughness of the tin-plated welding strip is reduced due to too low temperature drop of the tin-plated welding strip is avoided, and the tin-plated welding strip is easy to break.
The number of cooling wheels 21 is not limited by the invention, but the figure shows six cooling wheels 21, although more than six cooling wheels 21, for example ten, twelve or even more, may be provided for further cooling of the welding strip.
When the low-tin-plating welding strip straightening mechanism is used, as shown in the figures 1-8, a tin-plating welding strip blown by an air knife is directly introduced into a straightening mechanism 1, high-pressure steam with the temperature of about 120 ℃ is introduced into a straightening wheel in the straightening mechanism, so that the surface of the tin-plating welding strip is kept at the temperature of 120 ℃, the tin-plating welding strip is further easily straightened, then the tin-plating welding strip enters a cooling mechanism 2, rolls across the surface of the tin-plating welding strip through a cooling wheel, cools the low-tin-plating welding strip, shapes the low-tin-plating welding strip, and then winds the low-tin-plating welding; in subsequent use, after the tin-plated welding strip is paid off, compared with direct winding, the tin-plated welding strip is lower in bending degree, and is smoother during welding.
In the invention, the surfaces of the straightening wheel 12 and the cooling wheel 21, which are contacted with the welding strip, are smooth planes, thus being suitable for various flat welding strips; of course, if the solder strip is a circular solder strip, an annular groove may be optionally formed on the surface of the solder strip, so that the circular solder strip is embedded in the annular groove. The welding strip is guided to move by the annular groove.
