S4, in order to avoid that the electroplating effect of the zipper teeth 33 is deteriorated due to the fact that the electroplating layer is electroplated on the electroplating roller 34, the polishing blocks 40 are always tightly attached to the surface of the electroplating roller 34 to polish in the process of rotating the electroplating roller 34, so that the surface of the electroplating roller 34 is ensured to have no electroplating layer to keep the conductivity;
S5, abrasion occurs on the surface of the electroplating roller 34 in the process of continuous friction, so that the clamping and conveying effect of the electroplating roller 34 on the zipper strip 32 is reduced, at the moment, a part of the steel balls 44 extend out of the steel ball grooves 43 under the elastic effect of the elastic spiral strip 51, friction force can be increased when the zipper strip 32 is clamped and conveyed, the reduction of the clamping and conveying effect caused by abrasion is avoided, and the steel balls 44 are pressed back into the steel ball grooves 43 when encountering hard parts such as the zipper teeth 33, the polishing blocks 40 and the like, so that the electroplating roller 34 is prevented from being excessively worn, so that the zipper strip 32 cannot be clamped and conveyed;

Working principle: the apparatus is in an initial state, the roller frame 26 is positioned above the plating tank 10, an operator penetrates one end of the zipper tape between the two plating rollers 34, ensures that the plating rollers 34 are in close contact with the zipper teeth 33, ensures that the brushes 36 can wrap the zipper teeth 33, then places the metal plate 15 of the corresponding material into the first support 14, connects the metal plate 15 to the anode of the electric tank 13, controls the plating solution tank 22 to inject the plating solution in the spline rod 21 into the plating tank 10, closes the plating solution tank 22 when the amount of the plating solution in the plating tank 10 reaches the plating condition, and starts the electric tank 13 to be electrified.
The second motor 53 is controlled to cause the plating roller 34 to hold the fastener tape immersed in the plating solution, and at the same time, the first motor 19 is started to cause the two plating rollers 34 to rotate in opposite directions, the rotation of the two plating rollers 34 draws the zipper teeth 33 toward the plating roller 34, the zipper teeth 33 are always in close contact with the plating roller 34, and at the same time, the plating roller 34 transmits electric current to the zipper teeth 33 to cause them to be plated, and the roller shaft 31 moves toward one end under the action of the spiral groove 35 while the plating roller 34 rotates, and the zipper teeth 33 slide on the plating roller 34 and are kept in contact with the plating roller 34 all the time, so that the electroplated zipper teeth 33 are separated from the plating roller 34 to avoid excessive plating, and the zipper teeth 33 which are not plated are brought into contact with the plating roller 34 to be plated.
When the two electroplating rollers 34 rotate, the two driving belts 37 are driven to rotate, the brushes 36 on the two driving belts 37 continuously polish the zipper teeth 33 under the action of rotation, grease and burrs on the surfaces of the zipper teeth 33 are removed, the electroplating effect is ensured, and in the process that the zipper belts 32 continuously move towards one end, the brushes 36 also continuously pretreat the zipper teeth 33 which are not electroplated, so that the subsequent electroplating effect is ensured to be uniform and stable all the time.
In order to avoid the electroplating effect of the zipper teeth 33 being deteriorated due to the reduced conductivity of the electroplated layer on the electroplating roller 34, the polishing block 40 is always polished against the surface of the electroplating roller 34 during the rotation of the electroplating roller 34, so that no electroplated layer on the surface of the electroplating roller 34 is ensured to maintain the conductivity.
The surface of the electroplating roller 34 will be worn during the continuous friction process, so that the clamping and conveying effect of the electroplating roller 34 on the zipper strip 32 will be reduced, at this time, a part of the steel balls 44 will extend out of the steel ball grooves 43 under the elastic effect of the elastic spiral strip 51, the friction force will be increased during the clamping and conveying of the zipper strip 32, the reduction of the clamping and conveying effect caused by wear will be avoided, and the steel balls 44 will be pressed back into the steel ball grooves 43 when encountering hard parts such as the zipper teeth 33 and the polishing block 40, so as to avoid the excessive wear of the steel balls 44, so that the electroplating roller 34 can not clamp and convey the zipper strip 32 any more.
When the zipper is electrically plated, the second motor 53 is controlled to lift the electroplating roller 34, and the electroplating solution can be discharged from the drain valve 12 according to the next processing technology requirement to replace the electroplating solution, and meanwhile, the metal plate 15 with different materials can be replaced to carry out electroplating processing on the zipper teeth 33.
