[0002] A plywood cable is a common type of electrical wire, typically consisting of two parallel conductors. It is widely used in electronic circuits, particularly in low-voltage circuits such as audio equipment, computers, and televisions. Besides transmitting power, plywood cables can also be used to connect speakers, microphones, and other devices for transmitting audio signals.

[0026] The following is in conjunction with the appendix Figure 2-6 This application will be described in further detail.

[0027] This application discloses a cable trimming device, referring to... Figure 2 A wire cutting and slitting device includes a housing 1, a clamping device 2, a cutting device 3, a combing device 4, and a wire stripper 5. The housing 1 is a rectangular box and is mounted on a processing table or workbench. A processing cavity 11 is provided on one side of the housing 1, through which the wire to be processed passes. A slide rail 12 is provided on the housing 1 and inside the processing cavity 11, with the length of the slide rail 12 along the length of the processing cavity 11. The clamping device 2, the cutting device 3, and the combing device 4 are sequentially mounted on the slide rail 12 along the wire feeding direction, and the wire passes through the clamping device 2, the cutting device 3, and the combing device 4 in sequence. The clamping device 2 is used to keep the ribbon cable horizontally input into the cutting device 3, so that the two wires of the ribbon cable are on the same horizontal plane. The cutting device 3 is used to periodically cut the ribbon cable after passing through the cutting device 3, and then periodically cut the connection in the middle of the ribbon cable to divide the ribbon cable into two wires. The cut ribbon cable is conveyed to the combing device 4, which is used to output the ribbon cable in a horizontal state. The wire stripper 5 is set on the side of the frame near the combing device 4. The wire stripper 5 is a commercially available double-ribbed wire stripper 5. After the ribbon cable is conveyed by the conveying device, it is conveyed to the wire stripper 5, where the wire stripper 5 cuts and strips the ribbon cable.

[0028] One end of the ribbon cable is sequentially passed through the clamping device 2, the cutting device 3, and the combing device 4. The clamping device 2 feeds the ribbon cable into the cutting device 3 in a horizontal state. The cutting device 3 periodically cuts the connection point in the middle of the ribbon cable. Then, the combing device 4 feeds the ribbon cable into the wire stripping machine 5 in a horizontal state. The wire stripping machine 5 cuts the ribbon cable from the middle of the cutting point and strips the cut end. This eliminates the need for workers to manually separate the ribbon cable, thus improving production efficiency.

[0029] Reference Figure 2 and Figure 3 The clamping device 2 includes a mounting frame 21, a lower clamping block 22, and an upper clamping block 23. In this embodiment, the slide rail 12 has a T-shaped cross-section. In other embodiments, two parallel rods can also be used as the slide rail 12. A groove adapted to the slide rail 12 is provided at the bottom of the mounting frame 21. The mounting frame 21 is slidably mounted on the slide rail 12 and secured with bolts. The lower clamping block 22 is horizontally mounted on the mounting frame 21 by bolts. A lifting rod is vertically arranged on one side of the mounting frame 21. The upper clamping block 23 is slidably arranged on the lifting rod in the vertical direction, and the upper clamping block 23 is directly opposite the lower clamping block 22 in the vertical direction. A lifting component is provided on the housing 1 for driving the upper clamping block 23 to move along the lifting rod. The lifting component is a cylinder or a hydraulic cylinder. To prevent the cable from being damaged by pressure between the upper clamping block 23 and the lower clamping block 22, a rubber pad is provided on the opposite side of the upper clamping block 23 and the lower clamping block 22.

[0030] The cable to be processed is passed between the upper clamping block 23 and the lower clamping block 22. The upper clamping block 23 is driven to move toward the lower clamping block 22 to fit the cable. This ensures that the cable can only move horizontally when it moves past the clamping device 2 and will not twist, which facilitates the subsequent cutting of the cable.

[0031] Reference Figure 2 and Figure 4The slitting device 3 includes a slide table 31, a slitting table 32, a lifting table 33, and a cutter 34. The lower end of the slide table 31 has a groove adapted to the slide rail 12. The slide table 31 is slidably mounted on the slide rail 12 and secured with bolts. The slitting table 32 is detachably mounted on the slide table 31 by bolts. A lifting rod is vertically mounted on the slitting table 32, and the lifting table 33 is slidably mounted on the lifting rod in a vertical direction. A hydraulic cylinder or pneumatic cylinder is also provided on the housing 1 to drive the lifting table 33 to move along the lifting rod. The lifting table 33 is located directly above the slitting table 32. A notch 321 for cable routing is provided on the slitting table 32. The cutter 34 is detachably mounted on the bottom of the lifting table 33 by bolts, with the cutter 34 directly opposite the center of the notch 321. Meanwhile, first clamping blocks 35 are detachably installed on both sides of the notch 321 on the cutting table 32 via bolts. Multiple threaded holes are provided on the cutting table 32 to adjust the position of the first clamping blocks 35. By adjusting the distance between the first clamping blocks 35 on both sides of the notch 321, it can be adapted to accommodate cables of different widths, thus expanding its applicability.

[0032] By controlling the vertical movement of the lifting platform 33, the cutter 34 is driven to cut the ribbon cable passing through the cutting table 32. The cutter 34 cuts the PVC sheath of the ribbon cable from the middle along its length, thus dividing the ribbon cable into two conductors. It should be noted that the lifting platform 33 moves periodically in the vertical direction. By adjusting the moving speed of the ribbon cable and the holding time of the lifting platform 33 after its descent, the cutting length of the ribbon cable can be controlled, thereby adjusting the fork length at the end of the ribbon cable.

[0033] Reference Figure 2 and Figure 5 The combing device 4 includes a movable block 41, a guide frame 42, a roller 43, and a second pressing block 44. A groove adapted to the slide rail 12 is also provided on the movable block 41. The movable block 41 is slidably mounted on the slide rail 12, and the guide frame 42 is detachably mounted on the movable block 41 by bolts. The guide frame 42 is a rectangular frame. The roller 43 is rotatably mounted inside the guide frame 42 and located at the bottom of the guide frame 42. The roller 43 is horizontally positioned, and its length is perpendicular to the feeding direction of the cable. The second pressing block 44 is slidably mounted inside the guide frame 42 and located above the roller 43. An adjusting bolt threaded through the guide frame 42 and rotatably connected to the second pressing block 44 is provided. By turning the adjusting bolt, the position of the second pressing block 44 is adjusted, thereby bringing the second pressing block 44 into contact with the cable, ensuring that the cable remains horizontal as it passes between the second pressing block 44 and the roller 43. Meanwhile, multiple grooves 45 are also formed around the middle of the roller 43. The grooves 45 are used to accommodate the wires, prevent the wires from moving horizontally during movement, and process the wires with the subsequent wire stripping machine 5.

[0034] During the wire cutting process, the wire is output from the drum and input into the cutting device. The wire may be in a twisted state during this process. The clamping component straightens the wire and inputs it into the cutting device in a horizontal state. However, the clamping component only pushes the twisted part backward. The wire processing section is in a normal state, but the twist will accumulate between the wire drum and the cutting device, causing the wire in the processing section to twist and harden until it cannot be straightened by the clamping mechanism, thus affecting production.

[0035] Reference Figure 2 and Figure 6 A wire feeding device 6 is provided on the side of the housing 1 near the clamping device 2. A wire reel is mounted on the wire feeding device 6, and the wire is fed from the reel into the clamping device 2. During the wire feeding process, the wire feeding device 6 prevents twisting of the wire. The wire feeding device 6 includes a guide rail 61 and a slider 62. The guide rail 61 is annular and is vertically mounted to the processing table or workbench via support legs. The plane of the guide rail 61 is perpendicular to the wire feeding direction. A groove 621 is formed around the inner side of the guide rail 61, with a T-shaped cross-section. The slider 62 also has a T-shaped cross-section and is slidably disposed within the groove 621. Two sliders 62 are slidably disposed relative to each other within the groove 621. A snap-fit ​​groove is provided on the slider 62. The two ends of the shaft at the center of the wire reel are snapped between the two sliders 62 via the snap-fit ​​groove, and the shaft of the wire reel is fixed to the two sliders 62 by pins. Furthermore, in order to make the slider 62 slide smoothly in the groove 621, rolling balls 63 are also embedded on both sides of the slider 62, thereby converting the sliding friction of the slider 62 in the groove 621 into rolling friction.

[0036] The cable reel is installed between two sliders 62, which are slidably mounted on the guide rail 61. This allows the cable reel to rotate as it unwinds around its axis. As the number of twists between the cable reel and the clamping device 2 gradually increases, the torque generated by the twisting will cause the cable reel to rotate on the guide rail 61, thus causing the cable to tend to return to a straight state. This improves the problem of the cable being unable to be processed normally after too many twists have accumulated between the cable reel and the clamping device 2.

[0037] The implementation principle of the wiring cutting device in this application embodiment is as follows: one end of the wiring is sequentially passed through the clamping device 2, the cutting device 3, and the combing device 4. The clamping device 2 makes the wiring horizontally input into the cutting device 3. The cutting device 3 periodically cuts the connection in the middle of the wiring. Then, the combing device 4 makes the wiring horizontally output into the wire stripping machine 5. The wire stripping machine 5 cuts the wiring from the middle of the cutting point and strips the cut end, thus eliminating the need for workers to manually separate the wiring and improving production efficiency.
