The support frame 201 is connected with a deviation rectifying ring 202, and the deviation rectifying ring 202 is rotatably connected with a guide ball 203. The deviation rectifying ring 202 can rectify the cable to avoid contact between the outer sheath of the cable and the structural edge. The guide ball 203 can support and guide the cable by rotating itself, and the guide ball 203 arranged around can improve the protection effect of the cable. The shell 1 is provided with an adjusting groove 204 near the side of the support frame 201, and the support frame 201 is fixedly connected with an adjusting block 205 on the side. The adjusting block 205 is slidingly connected inside the adjusting groove 204, and the adjusting groove 204 can guide and limit the adjusting block 205, so that the adjusting block 205 and the support frame 201 can only move in the vertical direction.

[0030] On this basis, the deviation rectifying ring 202 is fixedly connected with a reset spring 206 arranged around the outside of the deviation rectifying ring 202. The reset spring 206 is fixedly connected to the support frame 201 at the end. The reset spring 206 can reset the deviation rectifying ring 202, so that the deviation rectifying ring 202 can move within a certain range when guiding the cable. At the same time, the reset spring 206 can buffer the cable when guiding the cable, so as to avoid deformation or damage of the outer sheath of the cable caused by excessive extrusion of the outer sheath of the cable by the guide wheel when the cable deviates.

[0031] It is worth noting that the adjusting block 205 is rotatably connected with a positioning ring 207 on the outside, and the adjusting block 205 is rotatably connected with a positioning block 208 on the inside. The positioning ring 207 can drive the positioning block 208, and the positioning ring 207 is fixedly connected with a protrusion on the inside, which can drive the positioning block 208 to rotate. The positioning block 208 is of "L" shape, and the adjusting groove 204 is provided with a positioning groove 209 corresponding to the structure of the positioning block 208. The end of the L-shaped positioning block 208 can cooperate with the positioning groove 209 to position the adjusting block 205 and the support frame 201.

[0032] In addition, the shell 1 is fixedly connected with a guide rod 210 at the bottom inside, and the guide rod 210 passes through the support frame 201. The support frame 201 is slidingly connected outside the guide rod 210, and the guide rod 210 can assist in guiding the movement of the support frame 201.

[0033] It is worth mentioning that the housing 1 is rotatably connected with the guide roller 306, the guide roller 306 is provided with three, the three guide rollers 306 are staggered in the middle of the housing 1, the guide roller 306 can guide the cable, so as to avoid the cable angle too small caused by the distance between the support frame 201 and the cable storage structure too far after the adjustment of the support frame 201. The top and middle guide rollers 306 can be combined with the bottom guide roller 306 to form a guide structure to guide the cable to adapt to the cable laying requirements of different height support frames.

[0034] Embodiment 2

[0035] As Figure 1 、 Figure 2 、 Figure 4 、 Figure 6 shown, on the basis of embodiment 1, the housing 1 is provided with a cable laying mechanism 3, which can store and lay the cable.

[0036] In this embodiment, the cable laying mechanism 3 includes a support rod 301 rotatably connected to the bottom of the housing 1, and a storage rack 302 rotatably connected to the outside of the support rod 301. The support rod 301 structure can support the cable laying mechanism 3, so that the cable laying mechanism 3 is in a vertical state.

[0037] Further, the support rod 301 is fixedly connected with a ratchet wheel 303, the storage rack 302 is rotatably connected with a ratchet 304, the inside of the storage rack 302 is fixedly connected with a torsion spring 305, the torsion spring 305 is fixedly connected with the support rod 301, and the side of the ratchet 304 is fixedly connected with a positioning spring, so that the ratchet 304 can keep rotating outward, and the ratchet 304 and the ratchet wheel 303 cooperate with each other to limit the reverse rotation of the storage rack 302. At the same time, the structure of the torsion spring 305 can drive the storage rack 302 through its elasticity, so that when the cable is broken accidentally during the drawing process, the cable can be automatically stored in the housing 1 by the elasticity of the torsion spring 305.

[0038] The utility model discloses a cable wire drawing machine wire inlet mechanism when using, first take down the cable from the storage frame 302 and wind the outside of the guide roller 306, after from the deviation ring 202, the cable end is passed into the wire drawing machine. In the process of wire drawing, the cable gradually releases wire from the outside of the storage frame 302, and the storage frame 302 can only rotate in the direction opposite to the wire release direction due to the limitation of the internal ratchet 304 structure. The storage frame 302 rotates the ratchet 303 and the support rod 301 through the internal ratchet 304 when releasing wire, and the support rod 301 can be connected with the wire drawing machine, so that the rotation speed of the support rod 301 is consistent with the wire drawing speed of the wire drawing machine. Due to the elastic effect of the torsion spring 305 inside the storage frame 302, the storage frame 302 rotates in the direction opposite to the wire release direction, thereby tightening the cable and avoiding excessive relaxation of the cable during wire release to affect subsequent operation. The guide ball 203 inside the deviation ring 202 can deviate and limit the outer wall of the cable from different directions. When it is necessary to adjust the position of the support frame 201 to adapt to wire drawing machines of different heights, the support frame 201 is longitudinally moved to the set position, the positioning ring 207 is rotated, the protrusion inside the positioning ring 207 pushes the one end of the positioning block 208 to rotate inward, the other end of the positioning block 208 rotates outward and moves to the inside of the positioning groove 209, thereby positioning the support frame 201.
