A group of locking screw holes are arranged side by side on the knife shaft, and the locking sleeve is fixed to the knife shaft through the locking screw and the locking screw hole. The locking nut is arranged on the locking sleeve through the internal and external threads to lock the corresponding rolling shear blade; there is no support between the pair of rolling shear blades on the knife shaft, and it cannot be used for large-sized copper strip shearing processing.

[0021] The specific implementation of the utility model will be further explained in detail below through the description of embodiments with reference to the accompanying drawings.

[0022] like Figure 1 As shown, the large-size copper strip trimming knife structure includes an upper scissors mounting shaft 1 and a lower scissors mounting shaft 4. The upper scissors mounting shaft is located directly above the lower scissors mounting shaft. A pair of upper rolling scissor blades 2 are provided on the upper scissors mounting shaft, and a pair of lower rolling scissor blades 5 are provided on the lower scissors mounting shaft. The upper rolling scissor blades on one side are arranged correspondingly to the lower rolling scissor blades on one side, and the upper rolling scissor blades on the other side are arranged correspondingly to the lower rolling scissor blades on the other side.

[0023] An upper rubber wheel 3 is provided on the upper scissors mounting shaft 1, and a lower rubber wheel 6 corresponding to the upper rubber wheel is provided on the lower scissors mounting shaft 4. There is a gap between the upper rubber wheel and the lower rubber wheel for the copper belt to pass through. The copper belt passes between a pair of rubber wheels, and the rubber wheels limit the sheared copper belt.

[0024] The utility model discloses a large-size copper strip edge shearing knife with reasonable structure design. A corresponding rubber wheel structure is arranged between a pair of rolling shear blades on the scissors mounting shaft. The edge shearing process is stable and reliable through the support of the elastic rubber wheel structure. The shearing edge of the copper strip is not prone to knife marks, which is beneficial to improving the quality of the copper strip product.

[0025] An upper rubber wheel 3 and a corresponding lower rubber wheel 6 form a pair of rubber wheel structures, which are arranged on the inner side of the rolling shear blade; that is, a pair of rubber wheel structures on each side are arranged on the shearing position to support the edge of the rolled copper belt.

[0026] A group of rubber wheels are arranged on the scissor mounting shaft, and adjacent rubber wheels are separated and arranged by sleeves sleeved on the scissor mounting shaft, and are arranged at intervals, which is conducive to heat dissipation. Furthermore, the gap between the upper rubber wheel and the lower rubber wheel is consistent with the height of the copper belt cutting edge, so that the copper belt edge is stably and reliably supported and knife marks are not easily formed.

[0027] A mounting hole is arranged at the center of the rubber wheel, and the inner edge of the mounting hole of the rubber wheel and the mounting shaft of the scissors are positioned and arranged by a keyway structure; the width of the rubber wheel is 10-20mm; and the manufacturing and installation are convenient.

[0028] The rubber wheel comprises a metal locating ring and a rubber ring sleeved on the metal locating ring. A keyway is arranged on the inner edge of the metal locating ring, and a convex key matching the keyway is arranged on the scissors mounting shaft, which is convenient for installation and has a stable and reliable structure. The thickness of the rubber ring is greater than that of the metal locating ring, and the positioning is reliable.

[0029] The above is only an explanation of the preferred embodiments of the present invention. The above technical features can be arbitrarily combined to form multiple embodiments of the present invention.

[0030] The utility model is described above by way of example in conjunction with the accompanying drawings.
