Description

Technical Field

[0001] This utility model relates to the field of power cord processing technology, and in particular to a fixed-length cutting device for power cord processing. Background Technology

[0002] Power cords are wires that transmit current. The main components of a power cord are an outer sheath, an inner sheath, and a conductor. Common conductors include copper and aluminum wires. A power cord length cutting device is an automated device used to precisely cut power cords to a preset length. It is widely used in wire harness processing in the electronics, electrical appliances, and communications industries.

[0003] Existing power cord processing fixed-length cutting devices have a relatively simple structure and a fixed wire feeding structure, making it difficult to adapt to different power cord diameters. The wire feeding process is unstable, affecting measurement accuracy. There are errors in the cutting length, and the cutting efficiency is low. The cutting process is prone to vibration, which can easily lead to deformation of the power cord end face and damage to the insulation layer, affecting subsequent connection processes.

[0004] Therefore, in view of the problems of low adaptability, unstable wire feeding process, low cutting efficiency, and easy deformation of the end face of the power cord in the existing power cord processing fixed length cutting device, a power cord processing fixed length cutting device can be designed. Utility Model Content

[0006] The technical solution of this utility model is as follows: a fixed-length cutting device for power cord processing, including a base; it also includes an upper guide roller and a cutter. Support plates are fixedly connected to the left and right ends of the base. Two lower guide rollers are rotatably connected between the two support plates. An upper guide roller is provided at the upper end of the lower guide roller. Guide grooves are opened on the surfaces of both the lower and upper guide rollers. An installation frame is fixedly connected between the two support plates. A cutting seat is fixedly connected to the upper end of the inner wall of the installation frame through a fixing block. A dust collection box is fixedly connected to the lower end of the inner wall of the installation frame. A bidirectional threaded rod is rotatably connected to the left side inside the installation frame. Movable seats are symmetrically threaded at both ends of the outer side of the bidirectional threaded rod. A cutter is fixedly connected to the end of the movable seat away from the cutting seat. A collection box is slidably connected to the front side of the upper end of the base. A controller is fixedly connected to the left end of the support plate.

[0007] Preferably, one end of each of the multiple power cords is passed through the lower guide roller and the cutting seat in sequence and placed in the corresponding guide groove. The two upper guide rollers move down simultaneously and clamp and limit the power cords with the lower guide roller through the guide groove. The lower guide roller rotates to drive the power cords to move. The controller controls the required power cord length. The bidirectional threaded rod rotates to drive the cutter to make relative movements and move the same distance, cutting the multiple power cords on the cutting seat simultaneously. At the same time, the dust collection box absorbs the debris generated at the moment of cutting. The cut power cords fall into the collection box along the lower guide roller.

[0008] Preferably, a rotating motor is fixedly connected to the right end of the right support plate, the output shaft of the rotating motor is fixedly connected to the lower guide roller, the two lower guide rollers are connected by a synchronous belt drive, and the rotating motor is electrically connected to the controller.

[0009] Preferably, the upper end of the support plate is fixedly connected to two support frames, and the lower end of each support frame is fixedly connected to a lifting cylinder. The output end of the lifting cylinder is fixedly connected to a mounting frame, the mounting frame is rotatably connected to the upper guide roller, and the lifting cylinder is electrically connected to the controller.

[0010] Preferably, there are six wire grooves evenly spaced, and each wire groove has a rubber layer fixedly connected to its upper end.

[0011] Preferably, a cutting groove is provided in the middle of the cutting seat, which is adapted to the cutting blade, and the same wire groove is provided at the upper end of the cutting seat.

[0012] Preferably, there are two dust collection boxes arranged symmetrically at the front and back. The lower end of the dust collection box has an air inlet, and the upper end of the mounting frame is fixedly connected to a manifold. The upper end of the manifold is connected to an external vacuuming device.

[0013] Preferably, a cutting motor is fixedly connected to the left side of the upper end of the mounting frame. The output shaft of the cutting motor moves through the mounting frame and is fixedly connected to a bidirectional threaded rod. A fixing rod is fixedly connected to the right side inside the mounting frame. A similar movable seat is slidably connected to the outside of the fixing rod. The cutting motor is electrically connected to the controller.

[0014] The beneficial effects of this utility model are:

[0015] This power cord processing fixed-length cutting device uses upper guide rollers and a cutter to sequentially pass one end of multiple power cords through the lower guide roller and the cutting seat, placing them in corresponding guide grooves. Depending on the different diameters of the power cords, the two upper guide rollers move downwards simultaneously, clamping and limiting the power cords with the lower guide roller through the guide groove. The rotation of the lower guide roller drives the power cord movement, preventing tangling and skipping during the feeding process. Simultaneous feeding of multiple power cords ensures high stability. The controller controls the required power cord length, and rotating the bidirectional threaded rod drives the cutter to move relative to it and travel the same distance, simultaneously cutting multiple power cords on the cutting seat. This reduces vibration and offset, resulting in a clean cut and improved cutting efficiency. Simultaneously, a dust collection box absorbs debris generated during cutting, keeping the work area clean and avoiding downtime for maintenance. The cut power cords fall along the lower guide roller into a collection box for easy collection. Attached Figure Description

An installation frame 6 is fixedly connected between the two support plates 2. A cutting seat 7 is fixedly connected to the upper end of the inner wall of the installation frame 6 through a fixing block. A dust collection box 8 is fixedly connected to the lower end of the inner wall of the installation frame 6.

The left side of the support plate 2... The controller 13 is fixedly connected to the end. During use, one end of each of the multiple power cords is passed through the lower guide roller 3 and the cutting seat 7 in sequence and placed in the corresponding guide groove 5. According to the different diameters of the power cords, the two upper guide rollers 4 move down simultaneously and clamp and limit the power cords with the lower guide roller 3 through the guide groove 5. The rotation of the lower guide roller 3 drives the power cords to move, avoiding wire entanglement and jumping during the wire feeding process. Multiple power cords are fed at the same time, which has high stability. The controller 13 controls the required power cord length. The rotation of the bidirectional threaded rod 9 drives the cutter 11 to make relative movements and move the same distance, cutting the multiple power cords on the cutting seat 7 simultaneously, reducing vibration and offset, and making the cut smooth and improving the cutting efficiency. At the same time, the dust collection box 8 absorbs the debris generated at the moment of cutting, keeping the work area clean and avoiding downtime for maintenance. The cut power cords fall into the collection box 12 along the lower guide roller 3 for easy collection.

[0024] Please see Figure 3 , Figure 4 and Figure 5In this embodiment, a rotating motor 14 is fixedly connected to the right end of the right support plate 2. The output shaft of the rotating motor 14 is fixedly connected to the lower guide roller 3. The two lower guide rollers 3 are connected by a synchronous belt drive. The rotating motor 14 is electrically connected to the controller 13. The controller 13 controls the rotating motor 14 to drive the two lower guide rollers 3 to rotate simultaneously via the synchronous belt. Two support frames 15 are fixedly connected to the upper end of the support plate 2. A lifting cylinder 16 is fixedly connected to the lower end of each support frame 15. A mounting frame 17 is fixedly connected to the output end of the lifting cylinder 16. The mounting frame 17 is rotatably connected to the upper guide roller 4. The lifting cylinder 16 is electrically connected to the controller 13. The lifting cylinder 16 drives the mounting frame 17 and the upper guide roller 4 to move up and down, clamping the power cord. Six guide grooves 5 are evenly distributed. A rubber layer 18 is fixedly connected to the upper end of each guide groove 5. The six guide grooves 5 improve production efficiency, and the rubber layer 18 reduces wear during the wire feeding process. A cutting groove 19 is opened in the middle of the cutting seat 7 for cutting. The groove 19 is adapted to the cutter 11. The upper end of the cutting seat 7 is provided with the same wire groove 5. The cutter 11 moves towards each other and enters the cutting groove 19 to cut synchronously, reducing vibration and deviation, and the cut is flat. The cutting groove 19 improves the cutting accuracy. There are two dust collection boxes 8 arranged symmetrically at the front and back. The lower end of the dust collection box 8 is provided with an air inlet. The upper end of the mounting frame 6 is fixedly connected to the manifold 20. The upper end of the manifold 20 is connected to the external dust collection equipment. The generated debris is sucked from the dust collection box 8 through the manifold 20 to the external dust collection equipment. The left side of the upper end of the mounting frame 6 is fixedly connected to the cutting motor 21.

The cutting motor 21 is electrically connected to the controller 13. The cutting motor 21 drives the bidirectional threaded rod 9 to rotate. The fixing rod 22 guides the movement of the moving seat 10 and improves the stability of the movement.

[0025] During operation, one end of each of the multiple power cords is passed through the lower guide roller 3 and the cutting seat 7 in sequence and placed in the corresponding guide groove 5. According to the different diameters of the power cords, the lifting cylinder 16 drives the mounting frame 17 and the upper guide roller 4 to move up and down. The lower guide roller 3 clamps and limits the power cords through the guide groove 5. The rotating motor 14 simultaneously drives the two lower guide rollers 3 to rotate and move the power cords. Multiple power cords are fed at the same time. The controller 13 controls the required power cord length. The cutting motor 21 drives the bidirectional threaded rod 9 to rotate. The cutter 11 moves relative to the cutting seat 7 and moves the same distance, cutting the multiple power cords on the cutting seat 7 simultaneously. At the same time, the dust collection box 8 absorbs the debris generated at the moment of cutting. The cut power cords fall into the collection box 12 along the lower guide roller 3 for easy collection.

[0026] Through the above steps, the upper guide roller 4 and the lower guide roller 3 clamp and limit the power line, which is suitable for power lines of different diameters. It avoids the situation of wire tangling and jumping during the wire feeding process, and has high stability. The cutter 11 moves towards each other and cuts synchronously, reducing vibration and deviation, resulting in a flat cut and improving cutting efficiency. This solves the problems of low adaptability, unstable wire feeding process, low cutting efficiency, and easy deformation of the end face of the power line in the existing power line processing fixed length cutting device.
