Description

TECHNICAL FIELD

[0001] The application relates to the technical field of wire processing equipment, in particular to a weaving and braiding clamping mechanism applied to a wire pretreatment automatic machine. BACKGROUND

[0002] With the rapid development of the wire market, the demand for wires is greatly improved, and the structure of the wires is gradually optimized to improve the data transmission capacity. For example, a USB data line currently relies on two ends to connect an input end and an output end, and the data receiving and outputting capacity of the two ends determines the data transmission capacity of the USB data line.

[0003] In the production of data lines, the ends of the cable at both ends need to be pretreated to facilitate subsequent processing. At present, the data line needs to be added with a copper foil bonding process to increase the conductivity of the data line and improve the data transmission capacity. The wire pretreatment automatic machine with a copper foil wrapping function in the prior art comprises a workbench, a plurality of clamping devices are slidably connected to the workbench, and the two ends of the wire are fixed with adjacent two clamping devices, so that the wire can be driven to slide relative to the workbench through the sliding of the clamping devices; the workbench is sequentially provided with an automatic wire cutting device, a rotating stripping device, a weaving and braiding device, a copper foil bonding device and a copper foil wrapping device for processing the wire.

[0004] The weaving and braiding device comprises a weaving and braiding mechanism and a clamping mechanism. The weaving and braiding mechanism pushes the weaving towards the direction of the outer skin still wrapped, so as to expose the part of the wire that needs to be wrapped with copper foil. The clamping mechanism comprises a clamping cylinder, which clamps the wire in a manner so that the end of the wire is not easy to bend during weaving and braiding. In actual use, it is found that the end of the wire will first touch the clamping cylinder and then move to the clamping point of the clamping cylinder during sliding. However, the wire may be bent to different degrees after being touched by the clamping cylinder. On the one hand, it may lead to the situation that the wire is not clamped after the clamping cylinder is started, and on the other hand, it will affect the weaving and braiding effect of the wire, thereby affecting the quality of the manufactured wire.

[0043] Referring to Figure 2 and Figure 3The opposite end faces of the two clamping blocks 21 are provided with intermeshing clamping teeth 212. Through the arrangement of the clamping teeth 212, the reliability of clamping the wire through the clamping block 21 is improved, so that the wire is not easy to slip relative to the clamping block in the process of turning knitting, the wire turning knitting effect is improved, and the quality of the wire made is improved.
