Description

Technical Field

[0001] This invention relates to the field of cable production equipment technology, and in particular to a fixed-length reel replacement system for marking weld defects. Background Technology

[0002] Wires and cables are wire products used to transmit electrical energy, information and realize electromagnetic energy conversion. They mainly consist of one or more insulated wire cores, as well as their respective sheaths, overall protective layer and outer sheath. Cables may also have additional uninsulated conductors.

[0003] Currently, the main method for marking cable weld points in cable extrusion equipment is manual estimation of weld point locations followed by manual reel changes. After reel changes, the wire is manually stripped to locate the weld point. This method of marking weld point defects relies entirely on the operator for quality control. The operator visually identifies the weld point location and marks it manually for subsequent processes to eliminate defects. However, this method is inaccurate, leading to waste and easy omissions. Meter marking is also handled manually by observing the meter mark position and stopping the process promptly, which requires highly skilled operators. To improve cable production efficiency and enable reel changes without stopping the machine, a fixed-length reel-changing system for marking weld point defects is proposed. This system accurately marks the location of weld point defects on a non-stop reel-changing production line and allows for rapid reel changes, facilitating secondary elimination in subsequent processes, reducing employee workload, increasing production efficiency, and ensuring cable quality. Summary of the Invention

[0004] This invention provides a fixed-length reel replacement system for marking weld defects, which solves the problems mentioned in the background art, reduces employee workload, increases production efficiency, and ensures cable quality.

[0005] The present invention provides the following solution to the above-mentioned technical problems: A fixed-length cable reel changing system for marking weld defects includes a cable extruder, a defect marking frame, a meter mark spraying frame, a cable outlet frame, a reel changing frame base, and a cable reel. Cable conveying frames are fixedly installed on both sides of the top of the defect marking frame and the meter mark spraying frame. Cable brackets are fixedly installed on the top of both the defect marking frame and the meter mark spraying frame. A cable defect detector and a marking spraying machine are fixedly installed on the top of the defect marking frame. A meter mark printer and a cutting hydraulic cylinder are fixedly installed on the meter mark spraying frame. A cutting tool is fixedly installed on the cutting hydraulic cylinder. An adjusting frame is fixedly installed on the top of the cable outlet frame. A second-stage brake stepper motor is fixedly installed on the inner wall of the adjusting frame. A reciprocating lead screw is fixedly connected to the second-stage brake stepper motor. A lead screw nut is threaded onto the outer wall of the reciprocating lead screw. A wire guide frame is fixedly installed on the top of the lead screw nut. Wire guide wheels are fixedly installed on both sides of the inner wall of the wire guide frame. A rectangular chassis is rotatably connected to the top of the reel changing frame base. A No. 5 brake stepper motor is fixedly installed on the inner wall of the reel changing frame base. The drive end of the No. 5 brake stepper motor is fixedly connected to the rectangular chassis. A lifting adjustment frame is fixedly installed on the top of the rectangular chassis. A No. 3 brake stepper motor is fixedly installed on the inner wall of the lifting adjustment frame. A No. 3 brake stepper motor is fixedly connected to a ball screw. A lifting nut is threaded onto the outer wall of the ball screw. Lifting sliders are fixedly connected to both sides of the lifting nut. Limit rods are fixedly connected to both sides of the inner wall of the lifting adjustment frame. A lifting bracket is fixedly connected to the lifting slider. A rotating disk is rotatably connected to the lifting bracket. A No. 4 brake stepper motor is fixedly installed on the lifting bracket. The drive end of the No. 4 brake stepper motor is fixedly connected to the rotating disk. A support cylinder is fixedly connected to the rotating disk. The cable reel is fitted onto the outer wall of the support cylinder. A limit plate is threaded onto the support cylinder.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, a cutting groove is provided on the top of the cable tray on one side corresponding to the cutting tool, so that the cutting tool can be inserted into the cutting groove to cut the cable.

[0008] Furthermore, the inner wall of the cable conveying frame is rotatably connected with conveying wheels. Each cable conveying frame has two conveying wheels, and each conveying wheel is fixedly mounted with a transmission gear. The transmission gears on both sides are meshed together. One conveying wheel is fixedly connected to a No. 1 brake stepper motor. Starting the No. 1 brake stepper motor can drive the two conveying wheels on both sides to rotate synchronously, thereby conveying the cable.

[0009] Furthermore, the outer wall of the guide wheel is configured with an arc-shaped structure, and the top of the cable tray is configured with an arc-shaped structure, so that the guide wheel can better fit with the cable, and the cable tray can limit the cable during cable transportation.

[0010] Furthermore, the lifting adjustment frame is provided with four parts, which are respectively placed on the four sides of the rectangular base. When the rectangular base rotates, the lifting adjustment frame can be adjusted to change its orientation, thereby facilitating the replacement of the plate.

[0011] Furthermore, the lifting slider has a sliding hole corresponding to the limiting rod, and the inner wall of the sliding hole is slidably connected to the limiting rod, so that the lifting slider can slide stably on the outer wall of the limiting rod.

[0012] Furthermore, limit strips are uniformly fixedly installed on the outer wall of the support cylinder, and limit grooves are opened on the inner wall of the cable reel corresponding to the limit strips, so that the cable reel can be stably fitted on the outer wall of the support cylinder. When the cable reel rotates, it can drive the cable reel to rotate synchronously for cable winding and unwinding.

[0013] Furthermore, the outer wall of the cable reel is uniformly connected to movable pulleys, which allows the cable reel to slide on the ground when placed on the ground, making reel changing more convenient.

[0014] The beneficial effects of this invention are as follows: This invention provides a fixed-length resealable plate system for marking solder joint defects, which has the following advantages:

[0015] 1. The cable defect detector at the top of the defect marking frame can detect weld defects in the cables passing through the bottom. After detecting a weld defect, it can send a signal to the marking spraying machine. After receiving the signal, the marking spraying machine can spray red paint on the defective area for marking, so that it can be processed in subsequent processing.

[0016] 2. The meter mark printer can print meter marks on the bottom of the cable. When the No. 2 brake stepper motor in the adjustment frame rotates the reciprocating screw, it can drive the wire frame to move back and forth through the screw nut. The No. 4 brake stepper motor can drive the rotating plate to rotate on the outer wall of the lifting bracket, which can drive the support cylinder and the cable reel on its outer wall to rotate synchronously. Under the guidance of the wire wheel, the cable can be evenly laid on the cable reel for winding, preventing the cable winding from being messy.

[0017] 3. When the meter mark printer prints the required length, it can send a signal to the cutting hydraulic cylinder and the No. 5 brake stepper motor and reset to zero to reprint. After receiving the signal, the cutting hydraulic cylinder can start to drive the cutting blade to press down and cut the cable. The No. 5 brake stepper motor can drive the rectangular chassis to rotate 90 degrees on the top of the reel changing frame base, so that the new cable reel can be aligned with the cable outlet frame. After the discharged cable is wound on the outer wall of the new cable reel, it can be rewound without stopping the machine.

[0018] 4. After the full cable reel is rotated and discharged, the No. 3 brake stepper motor can be started to rotate the ball screw. The ball screw can drive the two lifting sliders on both sides to slide on the outer wall of the limit rod through the lifting nut, so that the lifting bracket can be lowered to fit the lifting adjustment frame. After the moving pulley of the cable reel contacts the ground, the limit plate can be rotated to open. The outer wall of the cable reel is equipped with moving pulleys, so that the cable reel slides on the ground and gets off the support cylinder. A new cable reel can be replaced and fitted on the outer wall of the support cylinder. Tighten the limit plate for positioning. Start the No. 3 brake stepper motor to reverse and drive the cable reel to rise, ready for the next reel replacement.

[0019] 5. This type of weld defect marking and reel changing system can accurately mark the location of weld defects and quickly change reels on a non-stop reel changing production line, thereby facilitating secondary removal in subsequent processes, reducing employee workload, increasing production efficiency, and ensuring cable quality.

[0043] The specific working principle and usage method of this invention are as follows: The conveyor wheel 7 inside the cable conveyor frame 6 can rotate to convey the cable. After the cable is extruded by the cable extruder 1, it passes through the defect marking frame 2, the meter mark spraying frame 3, and the cable exit frame 4 before being conveyed to the reel base 5 for winding. The cable defect detector 11 at the top of the defect marking frame 2 can detect weld point defects in the cable passing through the bottom.
