Description

Technical Field

[0001] This utility model relates to the field of cable cutting technology, specifically to a cutting device for flat cables. Background Technology

[0002] In the field of cable cutting and processing, there is a problem of tension fluctuation during unwinding and winding. During the unwinding stage, the initial diameter of the cable roll is large, and the cable is loose during feeding. As the roll is consumed, the diameter gradually decreases, but the feeding tension increases. During the winding process, as the winding diameter increases, the required tension also changes, which can cause the cable feeding length to be artificially long or short. This results in a large deviation between the set length of the feeding mechanism and the actual cutting length, making it difficult to guarantee the cutting dimensional accuracy.

[0003] Therefore, it is necessary to provide a new technical solution to overcome the above-mentioned defects. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0024] In the description of this utility model, it should be understood that the terms "center," "lateral," "longitudinal," "front," "rear," "left," "right," "upper," "lower," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model. When a component is referred to as being "fixed to" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component at the same time. When a component is considered to be "set on" another component, it can be directly set on the other component or there may be an intermediate component at the same time. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0025] like Figures 1 to 6As shown, this utility model relates to a flat cable cutting device, comprising: a machine base, and an unwinding assembly, a guide rail, a cutting assembly, and a take-up roller arranged sequentially on the top of the machine base along the cable conveying direction.

[0026] The top of the guide rail is provided with a square guide groove, which is used to guide and limit the flat cable. A cable limiting block is slidably installed on the top of the square guide groove. The cable limiting block can slide along the width direction of the machine. A cable limiting gap is formed between the square guide groove and the cable limiting block. The cable limiting gap is used to limit the flat cable. Specifically, when it is necessary to limit a wider flat cable, the cable limiting block is slid laterally to move the cable limiting block away from the square guide groove, thereby increasing the cable limiting gap and making it easier to adapt to a wider flat cable.

[0027] An adjusting component for adjusting cable tension is provided between the unwinding assembly and the guide rail. The adjusting component includes: a column fixedly mounted on the top of the machine platform; a second motor fixedly mounted on the top of the column; a hinge rod fixedly connected to the output end of the second motor; a bearing connected to the other end of the hinge rod; and an adjusting roller rotatably connected coaxially to the bearing. By activating the second motor, the hinge rod rotates, thereby moving the adjusting roller and adjusting the tension of the flat cable. A limit groove is formed on the outer surface of the adjusting roller to laterally limit the cable and prevent deviation during feeding. The adjusting roller can rotate to avoid interfering with the flat cable transport.

[0028] The unwinding assembly includes: a first motor mounted on the top of the machine platform; a drive pulley driven by the output end of the first motor; a driven pulley driven by the drive pulley via a belt; a tension pulley fixedly mounted on the top of the machine platform and driven by the belt; and an unwinding roller coaxially connected to the driven pulley; the unwinding roller is driven by the first motor to unwind.

[0029] The cutting assembly includes: a mounting bracket installed on the unloading side of the guide rail, a telescopic cylinder installed on the top of the mounting bracket, and a cutter fixedly connected to the piston rod of the telescopic cylinder; a die is also provided below the cutter, the die cooperates with the cutter to cut, the die is installed on the top of the machine, and through the vertical cooperation design between the cutter and the die, the cutter is rigidly driven downward by the telescopic cylinder, and combined with the fixed positioning of the die, the cutting edge is ensured to be flat and the size is consistent.

[0030] The mounting bracket has a square groove for guiding and limiting the flat cable. An adjusting slider for adjusting the thickness of the square groove is located on the unloading side. The adjusting slider is slidably connected to a guide block, which is fixedly mounted on the unloading side of the mounting bracket. A threaded connecting block is fixedly mounted on the adjusting slider. A threaded hole is formed in the center of the threaded connecting block, and a screw is threaded into the threaded hole. A handwheel is fixedly connected to the top of the screw. By rotating the handwheel, the screw rotates, causing the adjusting slider to slide up and down, thereby changing the relative position between the adjusting slider and the square groove. This allows for adjustment of the thickness of the square groove, accommodating flat cables of different thicknesses.

[0031] Preferably, the adjusting sliders are configured in two sets and symmetrically arranged on the upper and lower sides of the square groove. When the screw is rotated, the upper and lower adjusting sliders can be adjusted simultaneously to facilitate centering the flat cable.

[0032] As can be seen from the above description, the embodiment of this application uses an adjusting component to adjust the cable tension. A machine base is used, with an unwinding component, a guide rail, a cutting component, and a take-up roller sequentially arranged on the top of the machine base along the cable conveying direction. An adjusting component for adjusting the cable tension is provided between the unwinding component and the guide rail. The adjusting component includes: a column fixedly installed on the top of the machine base; a second motor fixedly installed on the top of the column; a hinge rod fixedly connected to the output end of the second motor; a bearing connected to the other end of the hinge rod; and an adjusting roller rotatably connected to the bearing. This achieves dynamic adjustment of the cable tension, ensuring stable and controllable tension during feeding. It solves the problem of cable feeding lengths being artificially long or short, leading to significant deviations between the set length of the feeding mechanism and the actual cutting length, making it difficult to guarantee cutting dimensional accuracy.
