[0002] At present, during the production process of copper enameled wire, the copper material needs to be switched to a new shaft of copper material before it is almost used up, and the tail end of the copper material that is about to be used up needs to be connected to the head end of the copper material on the new shaft.

[0003] However, because the pay-off roller where the copper material is located continues to rotate with the pulling of the calender, the tail end of the copper material continues to rotate with the pay-off roller, and wiring cannot be made. In order to connect the wires, one person is required to pull the copper material out about 30 meters to reserve enough copper material buffer, one person cuts the copper wire in use for wiring, and one person holds the wire steady to avoid wire breakage caused by entanglement during the calendering process. The operation requires the cooperation of multiple people, and the pulled copper material will scratch the ground and affect its use. Utility Model Content

[0004] The technical problem to be solved by the present invention is to overcome the existing defects and provide a copper wire splicing device. When preparing to replace a new wire pay-off roller, only one person is required to first pull out the copper material on the used wire pay-off roller and wind it on the cache vertical cylinder, and then cut the copper material between the cache vertical cylinder and the used wire pay-off roller. The copper material wound on the cache vertical cylinder can be released from the top, and the cache vertical cylinder does not need to be rotated. At this time, the cut end of the copper material is connected to the copper material on the new wire pay-off roller in situ, and only one person is required to operate. The pulled out copper material is wound on the cache vertical cylinder and will not be scratched on the ground, thereby avoiding waste of copper material. Finally, the original wire pay-off roller is removed from the wire pay-off bracket, and the new wire pay-off roller is placed on the wire pay-off bracket, which is convenient for changing the copper shaft, can reduce the number of operators, and can effectively solve the problems in the background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a copper material pay-off and splicing device, comprising:

[0006] The wire-laying bracket includes a U-shaped plate, a rear support rod, a front support rod, a side plate, a supporting rod, a slope and a rotating shaft limit seat. The U-shaped plates are provided with two, and the two U-shaped plates are arranged correspondingly up and down. The left and right ends of the rear sides of the two U-shaped plates are respectively connected by two vertical rear support rods, and the left and right ends of the front sides of the two U-shaped plates are respectively connected by two vertical front support rods. Each front support rod is connected to the corresponding rear support rod on the rear side through the side plates, and the sides of the two side plates close to each other are respectively fixedly connected to two supporting rods, and the top of the supporting rod is provided with a slope that is higher in the front and lower in the back, and the rear end of the slope is fixedly connected to the rotating shaft limit seat;

[0008] The mobile cart is located in front of the copper material pay-off mechanism, and the copper material connection buffer assembly is installed on the upper side of the mobile cart.

[0009] The U-shaped plate, the rear support rod, the front support rod and the side plates constitute the main body of a wire-paying bracket, the supporting rod is used to support the end of the copper wire-paying mechanism, the slope and the rotating shaft limit seat cooperate to limit the end of the copper wire-paying mechanism. When placing the copper wire-paying mechanism on the slope, it is only necessary to use a forklift to place the end of the copper wire-paying mechanism on the top front end of the supporting rod, and then roll the copper wire-paying mechanism backward. The end of the copper wire-paying mechanism rolls backward along the slope until it stops at the rotating shaft limit seat, which makes it convenient to quickly install the copper wire-paying mechanism in place. The copper wire-paying mechanism is used to use linear copper materials. The mobile cart is convenient for moving the copper material to continue the cache component. When in use, it is The moving cart moves the copper material splicing cache assembly to the front of the wire-paying bracket. When wiring is required, the copper on the supporting copper material wire-paying mechanism is pulled out and wound around the copper material splicing cache assembly. Generally, in order to leave redundancy and avoid the copper material used in the calendering machine from breaking, there will be a part of copper material on the supporting copper material wire-paying mechanism. At this time, the copper material between the cache vertical cylinder and the supporting copper material wire-paying mechanism is cut off. The copper material wound on the copper material splicing cache assembly is continuously used by the calendering machine, and the cut end of the copper material is connected to the copper material on the new supporting copper material wire-paying mechanism with the help of a wiring machine. The original supporting copper material wire-paying mechanism is removed from the wire-paying bracket, and the new supporting copper material wire-paying mechanism is placed on the wire-paying bracket.

[0010] Furthermore, the pay-off bracket further includes support rods, through which the bottoms of the two side panels are fixedly connected to the lower U-shaped plate. The support rods are used to improve the structural stability of the side panels and prevent the side panels from being deformed by excessive weight of the copper material pay-off mechanism.

[0011] Furthermore, the copper material pay-off mechanism includes a pay-off shaft, a retaining ring, and a pay-off roller. The left and right ends of the pay-off shaft are respectively placed on two slopes, and the left and right ends of the pay-off shaft are respectively located in front of two shaft limit seats. The middle part of the pay-off shaft is rotatably sleeved with the pay-off roller, and the pay-off shaft is sleeved with two retaining rings at the ends of the pay-off roller.
