AI Technical Summary
In existing steel cord phosphating equipment, the connection between a single steel wire and the cathode guide wheel generates a large amount of heat and has low conductivity. Furthermore, the cathode roller needs to be replaced after wear, which affects production efficiency.
The cathode gun is designed with multiple gun body structures. Each gun body structure contacts the steel wire through a conductive head, forming multiple contact points to increase conductivity. When a single conductive head wears out, it can be replaced individually, keeping other conductive heads in contact with the steel wire, thus enabling production without stopping.
It reduces heat generation at the contact points, improves conductivity, reduces power loss, and enables continuous use of the cathode gun through redundant design, avoiding production stoppages due to wear and improving production efficiency.

[0030] In order to understand the technical content of the utility model more, specific embodiments are raised and the following is described with the aid of the accompanying drawings.
[0031] Combining Figure 1 and 2 shown, the first aspect of the utility model proposes a cathode gun 30, including multiple gun body structures, multiple gun body structures are arranged along the extension direction of the steel wire 100, can increase the contact point between the steel wire 100, reduce the contact temperature of each contact point, the gun body structure includes the gun body 10 and the conducting head 20, the conducting head 20 is detachably connected with the gun body 10.
[0032] Among them, the conducting head 20 as a consumable, when the conducting head 20 is worn, the conducting head 20 can be replaced, and when the conducting head 20 is replaced, the other conducting head 20 corresponding to the steel wire 100 still maintains contact with the steel wire 100, and does not affect the phosphating treatment of the steel wire 100.
[0033] Specifically, combining Figure 2 shown, the gun body 10 includes the gun body body 11, the first end of the gun body body 11 is provided with the hook 12, the second end of the gun body body 11 is provided with the connecting plate 13, and the hook 12 is used to connect the cathode structure 40.
[0034] Optionally, the cathode structure 40 includes a hanger, the hanger includes multiple cross rods, the hook 12 is hung to the cross rod, the gun body body 11, the hook 12 and the connecting plate 13 are all conductive materials, and electric connection is realized by contact with the cathode structure 40.
[0035] The conducting head 20 is detachably connected to the connecting plate 13, and the conducting head 20 is provided with the groove 21 in contact with the steel wire 100.
[0036] Optionally, the conducting head 20 is made of conductive material, and the hardness thereof is lower than that of the steel wire 100, so that the steel wire 100 is not worn when maintaining contact with the steel wire 100, and the steel wire 100 can be positioned through the groove 21, avoiding the steel wire 100 from being separated from the contact with the conducting head 20 when sliding.
[0037] Further, the plurality of gun body structures are arranged along the length direction of the steel wire 100, and form a plurality of contact points with the steel wire 100.
[0038] It can be understood that by forming a plurality of contact points with the single steel wire 100, the current passing through each contact point can be reduced, and thus the heat generation of the contact point can be reduced, the conduction efficiency can be improved, and the wear of the conduction head 20 can be reduced. In addition, the design of the contact point redundancy can maintain the state of the steel wire 100 being in communication with the cathode when any one of the contact points of the conduction head 20 needs to be replaced, and the replacement of the conduction head 20 can be completed while the steel wire 100 is in communication with the cathode, thereby improving the yield.
[0039] In combination with Figure 3 As shown, the hook 12 is arranged in an open direction towards the direction of the steel wire 100, so that after the hook 12 is mounted to the cathode structure 40, especially to the crossbar of the hanger, the conduction head 20 can be attached to the surface of the steel wire 100 and swing up and down with the jumping of the steel wire 100.
[0040] In this way, when the steel wire 100 jumps during the conveying process, the conduction head 20 can always maintain contact with the steel wire 100, so that the steel wire 100 is in the conduction loop.
[0041] Further, the gun body 11 is provided with a counterweight 14, which is arranged in the direction close to the connecting plate 13 and the steel wire 100. In this way, by arranging the counterweight 14, the contact pressure between the conduction head 20 and the steel wire 100 can be increased, so that the contact between the two is more close, and especially when the steel wire 100 shakes, the contact between the conduction head 20 and the steel wire 100 can be maintained.
[0042] In an optional embodiment, the gun body 11 and the counterweight 14 are integrally formed.
[0043] Among them, an obtuse angle is formed between the connecting plate 13 and the gun body 11. In this way, the connecting plate 13 extends upward at the bottom of the gun body 11, which is beneficial to the installation of the conduction head 20, and makes the conduction head 20 and the steel wire 100 have a certain included angle, which is beneficial to maintaining the contact between the conduction head 20 and the steel wire 100 when the steel wire 100 shakes.
[0044] In combination with Figure 4 As shown, the lower portion of the connecting plate 13 is provided with a positioning groove 131, and the upper portion of the conduction head 20 is provided with a protrusion 22, which is clamped into the positioning groove 131, so that the conduction head 20 cannot rotate relative to the connecting plate 13 along its axis.
[0045] That is, the extending direction of the steel wire 100 is in the same plane with the extending direction of the positioning groove 131 and the extending direction of the groove 21, so that the conductive head 20 can keep stable position during the whole use period and cannot be deflected, the wear between the steel wire 100 and the conductive head 20 can only deepen the depth of the groove 21, and cannot make the groove 21 be widened or even be worn laterally (the lateral wear can make the steel wire 100 be separated from the groove 21), so that the steel wire 100 and the conductive head 20 can keep contact during the whole use period.
[0046] Preferably, the extending direction of the groove 21 is in the same plane with the extending direction of the positioning groove 131 and has an included angle with each other, so that the groove 21 of the conductive head 20 can keep larger contact area with the steel wire 100 when the steel wire 100 swings up and down.
[0047] In the alternative embodiment, the top of the convex block 22 is provided with a threaded groove, the connecting plate 13 is provided with a threaded connecting piece 23, the threaded connecting piece 23 penetrates through the connecting plate 13 and is connected into the threaded groove, so that the conductive head 20 and the connecting plate 13 are relatively fixed.
[0048] In this way, the threaded connection facilitates the installation and dismounting of the conductive head 20 and the connecting plate 13, so that the conductive head 20 can be quickly and conveniently replaced after wear and tear.
[0049] Preferably, the outer wall of the gun body 11 is provided with an insulating layer 15. The insulating layer 15 can be a polytetrafluoroethylene insulating layer or an ABS resin, epoxy resin and the like insulating coating layer.
