[0001] This utility model relates to the field of low-voltage communication harness production, and specifically to a slitting device for low-voltage communication harnesses. Background Technology

[0002] Low-voltage communication harnesses typically refer to cables and connecting components used in low-voltage communication systems. These harnesses are widely used in various devices and systems, such as automobiles, network equipment, security systems, audio and video equipment, and smart homes. Their main function is to transmit data and control signals.

[0020] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0021] Please refer to the appendix. Figures 1-4 The present invention provides a low-voltage communication harness cutting device, including a base 1, a gantry 2 fixed at the top center of the base 1, a cutter 3 mounted on the gantry 2 via a feed assembly for cutting the low-voltage communication harness to be processed, a first clamping assembly mounted on both sides of the top of the base 1 via an adjustment assembly, and a second clamping assembly fixed on the feed assembly.

[0022] The adjustment assembly includes two horizontally arranged movable bases 4. The bottom ends of the two movable bases 4 are symmetrically fixed to the top two sides of the base 1. A servo motor 5 is horizontally fixed to the inner side of each movable base 4. A lead screw 6 is fixed to the output shaft of the servo motor 5. A movable sleeve 7 is threadedly connected to the surface of the lead screw 6. A limit plate 8 is vertically fixed to the top of the movable sleeve 7. A strip-shaped limit hole 9 is horizontally opened at the top of the movable base 4. The top of the limit plate 8 vertically penetrates the strip-shaped limit hole 9, and the surface of the limit plate 8 is in contact with the wall of the strip-shaped limit hole 9. A movable plate 10 is fixed to the top of the limit plate 8. Specifically, under the combined limiting action of the limit plate 8 and the strip-shaped limit hole 9, when the servo motor 5 runs and drives the lead screw 6 to rotate in both directions, the movable sleeve 7 threadedly connected to the surface of the lead screw 6 can move back and forth horizontally, thereby driving the movable plate 10 to move back and forth horizontally synchronously.

[0023] The first clamping assembly includes two right-angle support plates 11. The bottom ends of the two right-angle support plates 11 are respectively fixed to the top ends of two movable plates 10. The top ends of the movable plates 10 are each fixed with a first lower pressure plate 12. The top ends of the right-angle support plates 11 are each vertically fixed with a first electric push rod 13. The bottom ends of the output shafts of the first electric push rods 13 are each fixed with a first upper pressure plate 14. The first upper pressure plate 14 is located directly above the first lower pressure plate 12. Specifically, when the first electric push rod 13 is running, it can drive the first upper pressure plate 14 to move downward. In conjunction with the use of the first lower pressure plate 12, the two ends of the low-voltage communication harness can be clamped and fixed. When the movable plates 10 move laterally back and forth, it can drive the two right-angle support plates 11 to move laterally back and forth synchronously. This allows the two right-angle support plates 11 to move towards each other or in opposite directions, so that the first upper pressure plate 14 and the first lower pressure plate 12 can clamp and fix the two ends of low-voltage communication harnesses of different lengths. This has a wide range of applications.

[0024] The feeding assembly includes a vertically arranged second electric push rod 15. The bottom end of the second electric push rod 15 is fixed to the top of the gantry 2. A connecting plate 16 is fixed to the bottom end of the output shaft of the second electric push rod 15. The top end of the cutter 3 is fixed to the middle of the bottom of the connecting plate 16. Specifically, when the second electric push rod 15 is running, it can drive the cutter 3 to move down through the connecting plate 14 to perform feeding operations, thereby enabling the cutter 3 to cut the low-voltage communication harness.

[0025] The second clamping assembly includes two vertically arranged spring seats 17. The top ends of the two spring seats 17 are symmetrically fixed to the bottom ends of the connecting plate 16. A return spring 18 is vertically fixed to the top of the inner wall of each spring seat 17. A limit block 19 is fixed to the bottom end of each return spring 18. A guide rod 20 is vertically fixed to the bottom end of each limit block 19. A limit through hole 21 is opened at the bottom end of each spring seat 17. The guide rod 20 vertically passes through the limit through hole 21, and the surface of the guide rod 20 is in contact with the wall of the limit through hole 21. A second upper pressure plate 22 is fixed to the bottom end of each guide rod 20. A second lower pressure plate 23 is symmetrically fixed to both sides of the top of the base 1. The two second lower pressure plates 23 are respectively located at the two upper pressure plates 22. Directly below the second upper pressure plate 22, specifically, when the second electric push rod 15 moves and drives the cutter 3 downward to cut the low-voltage communication harness, the second upper pressure plate 22 can move downward synchronously. Under the elastic force of the return spring 18, in conjunction with the use of the second lower pressure plate 23, the second upper pressure plate 22 can press the low-voltage communication harness again. That is, while the device has the function of cutting the low-voltage communication harness, it can also realize the function of pressing the low-voltage communication harness at multiple points, thereby effectively avoiding the situation of the low-voltage communication harness being cut by the cutter, which is beneficial to the cut quality of the low-voltage communication harness and thus beneficial to the product quality of the low-voltage communication harness.

[0026] It should be noted that the device is electrically connected to an external main controller and 220V AC mains power, and the main controller can be an existing technology device such as a computer for control.
