In all examples shown and discussed herein, any particular value should be construed as merely illustrative, and not limiting. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, further discussion thereof is not required in subsequent figures.

As shown in fig. 1 to 4, the apparatus for cutting a wire cord fabric of the present embodiment includes: frame 10, upper cut-off knife mechanism, lower cut-off knife mechanism, adjustment mechanism and display instrument subassembly 50. The upper cutter mechanism is disposed on the frame 10, and includes an upper cutter frame 21 and an upper cutter 22 disposed on the upper cutter frame 21. The lower cutter mechanism is disposed on the frame 10 below the upper cutter mechanism, and includes a cutter plate 31 movably disposed on the frame 10 and a lower cutter 32 attached to the cutter plate 31 in a moving direction of the cutter plate 31 (an arrow direction shown rightward in fig. 1). A cutter gap H is provided between the upper cutter 22 and the lower cutter 32. The adjusting mechanism is arranged on the knife board 31 and connected with the frame 10. The adjusting mechanism includes a first mounting hole (not shown), a screw 43, an elastic member 44, and a first nut 45, which are coaxially disposed. The first mounting hole is arranged on the cutter plate 31, the screw hole is arranged on the machine frame 10, and an adjusting gap is formed between the cutter plate 31 and the machine frame 10. The screw 43 is inserted into the first mounting hole and the screw hole, and the elastic element 44 and the first nut 45 are arranged in the adjusting gap and sleeved on the screw 43. The first nut 45 presses the elastic member to make the elastic member 44 apply an elastic force to the knife plate 31, and the screw 43 is screwed to drive the knife plate 31 to move to adjust the size of the adjusting gap and thus the size of the cutter gap H. The display meter unit 50 is provided on the knife board 31 and abuts against the chassis 10.

By applying the technical solution of this embodiment, the adjusting mechanism includes a first mounting hole, a screw 43, an elastic member 44, and a first nut 45, which are coaxially disposed. The first mounting hole is formed in the cutter plate 31, the screw hole is formed in the rack 10, an adjusting gap is formed between the cutter plate 31 and the rack 10, the screw 43 penetrates through the first mounting hole and the screw hole, and the elastic piece 44 and the first nut 45 are arranged in the adjusting gap and sleeved on the screw 43. The adjustment gap facilitates the placement of the resilient member and the first nut 45. In this application, first nut 45 extrudees the elastic component to make elastic component 44 exert elasticity to cutting board 31, because screw rod 43 and elastic component 44 coaxial setting, make this elasticity action of points encircle around screw rod 43, make the pretightning force that screw rod 43 received more even, avoid among the correlation technique elasticity action of points all to be located one side of adjusting screw rod and make adjusting screw rod's axis to take place the slope for movable table, the not accurate phenomenon of clearance volume that leads to the percentage table to show. Meanwhile, the elastic piece 44 applies elastic force to the knife plate 31, so that the movable gap between the screw 43 and the first mounting hole can be effectively reduced, and the matching error is effectively reduced. Screwing the screw 43 drives the knife board 31 to move to adjust the size of the adjusting gap so as to adjust the size of the cutter gap H. The numerical value display of the display gauge assembly 50 clearly and reliably displays the adjustment amount of the adjusted cutter gap. Therefore, the technical scheme of this embodiment has effectively solved among the relevant art that the clearance volume that the percentage table shows is not accurate, leads to the problem of blind adjusting screw.

It should be noted that, the driving force for driving the knife plate 31 to move by screwing the screw 43 is larger than the elastic member 44 applies the elastic force to the knife plate 31, and the screw 43 can move in the arrow direction shown rightward in fig. 1 relative to the first nut 45.

In addition, the inventor finds that the movable workbench of the related art comprises an upper side part and a lower side part, the lower cutter is connected to the upper side part, the adjusting screw is arranged on the lower side part, and at the moment, when the adjusting screw is used for adjusting the gap between the upper cutter and the lower cutter, the adjusting screw is screwed to generate torque between the adjusting screw and the upper side part, so that the movable workbench can shake, the displayed numerical value of the dial indicator is inaccurate, and the gap between the upper cutter and the lower cutter cannot be accurately adjusted.

As shown in fig. 3, in the present embodiment, the axis of the first mounting hole is located in the center plane Y in the thickness direction of the cutter plate 31. The distance from the center plane Y to the upper surface of the cutter plate 31 is equal to the distance from the center plane Y to the lower surface of the cutter plate 31. Thus, the extrusion force of the screw 43 on the knife board 31 is in the central plane Y, no moment is generated, and the shaking of the knife board 31 is avoided. Meanwhile, the elastic force applied to the knife board 31 by the elastic piece 44 and the pressing force applied to the knife board 31 by the screw 43 can be partially offset, so that the screw 43 can drive the knife board 31 to move more reliably and stably. Therefore, the setting mode can solve the problem that the gap between the upper knife and the lower knife cannot be accurately adjusted due to inaccurate display numerical values of the dial indicator.

As shown in fig. 3 and 5, in the present embodiment, the adjusting mechanism further includes a bearing 46 inserted into the first mounting hole and a retainer ring 47 located in the adjusting gap, and the retainer ring 47 is interposed between the elastic member 44 and the bearing 46. The provision of the bearing 46 can reduce the friction coefficient between the screw 43 and the first mounting hole, and the rotation of the adjustment screw 43 becomes smoother. The retainer 47 is provided to provide a support surface to prevent the elastic force applied by the elastic member 44 to the knife plate 31 from tilting. The bearings 46 of the present embodiment are preferably axial bearings, two of which are provided at both ends of the first mounting hole, respectively.

As shown in fig. 3 and 5, in the present embodiment, the frame 10 includes a frame body 11 and a second nut 12 disposed on the frame body 11, and an inner hole of the second nut 12 forms a screw hole. The second nut 12 is simple in structure, low in cost and easy to obtain. The screw 43 comprises a polished rod section cooperating with the first mounting hole, a first threaded section cooperating with the first nut 45 and a second threaded section cooperating with the threaded hole. Such a screw 43 can perform different functions, and can reduce the cost.

As shown in fig. 3 and 5, in the present embodiment, the elastic member 44 includes a plurality of disc springs. The disc spring has a high strength and a small deformation amount compared to the spring, and the force of the first nut 45 pressing the elastic member 44 is less likely to incline, resulting in a small error.
