Annealing, carries out DC voltage heating between the first annealing wheel, the second annealing wheel；Entered by the flat copper wire of the second annealing wheel output
Enter constant temperature deionized water and carry out cooling annealing, thus reduce flat copper wire hardness, obtain the purpose of certain yield strength, obtain
Qualified flat copper wire, be re-fed into tin plating coating workshop section.Find in process of production, enter the flat copper wire of the first annealing wheel
Still there is the bigger transmission pulling force from a upper equipment, through the flat copper wire of the first annealing wheel under the effect of DC voltage
Deliquescing, at this moment, the transmission pulling force of its rear end is just easy for being broken, and breaks position the most all at the first annealing wheel and direct current
Between voltage heater.If control the hardness of flat copper wire in order to avoid breaking, may result in annealing brownout, move back
Fire weak effect, it is impossible to yield strength does not reaches desired quantity, has influence on the using effect of final photovoltaic welding belt；Further, flat copper
Line is pulled off every time, and calender all must carry out threading again after shutting down, production efficiency significantly reduces, and also brings a large amount of simultaneously
Need the waste product of recycling, add workman's workload.
Utility model content
For solving the problems referred to above that prior art exists, the purpose of this utility model is that offer one can shielded flat
Transmission pulling force on copper cash, make the photovoltaic welding belt annealing device that flat copper wire not easy fracture, work efficiency are high, annealing effect is good.
For solving above-mentioned technical problem, this utility model be the technical scheme is that
A kind of photovoltaic welding belt annealing device, including the first annealing wheel, the second annealing wheel, at the first annealing wheel, second moves back
Between fire wheel, DC heating device is set, it is characterised in that: in the junction of flat copper wire Yu the first annealing wheel, pulling force screen is set
Cover mechanism；Described pulling force shielding body includes cylinder, is provided with piston in cylinder, piston rod one end is fixing connect piston, another
End stretches out cylinder and is connected with fabric wheel, and during piston rod elongation, fabric wheel is pressed on the driving face of the first annealing wheel, described work
Stopper rod is positioned on the body of rod of cylinder and is set with line ball spring；The gas circuit of cylinder connects compressed air source, institute by gas pipeline
State the electromagnetic valve being additionally provided with on gas pipeline for controlling gas pipeline folding.
Further improvement of the utility model is: described line ball spring is cylinder-shaped compression spring.
Further improvement of the utility model is: described line ball both ends of the spring is separately fixed in piston end surface and cylinder
On wall, and line ball spring does not contacts with piston rod.
Further improvement of the utility model is: described piston rod is perpendicular with the flat copper wire entering the first annealing wheel
Angle.
Owing to have employed technique scheme, the technological progress that this utility model obtains is:
This utility model provides a kind of photovoltaic welding belt annealing device, arranges pulling force on the driving face of the first annealing wheel
Shielding body, by fabric wheel and the pressuring action of the first annealing wheel, in the flat copper wire that will pass with transmission pulling force
Effectively shielding, not by there is not biography between flat copper wire and the flat copper wire having passed through the first annealing wheel of the first annealing wheel
Dynamic pulling force, whole flat copper wire uniform force, will not rupture easily；Therefore, the DC voltage of DC voltage heater
Can add is very big, significantly improves annealing effect, and yield strength is reduced further, and the concordance of yield strength is further
Improving, the quality of product, quality stability are all greatly improved, and percent defective significantly reduces.
Owing to efficiently solving the problem of flat copper wire fracture, therefore without frequent shutdown again, production efficiency is shown
Writing and improve, production process is more stable, and the service life of calender is also greatly prolonged.
