Description

Technical Field

[0001] This utility model relates to the field of wire stripping machine technology, specifically to a cutter head structure for a multi-core cable stripping machine. Background Technology

[0002] In the manufacturing of film capacitors, the leads, as the core component connecting the internal electrodes to the external circuit, directly determine the electrical performance, reliability, and service life of the capacitor through their stripping quality. Film capacitor leads typically use fine-gauge multi-core cables, such as multi-strand copper wires covered with insulation layers like PVC or PTFE. These insulation layers must be tightly bonded to the internal fine conductors to meet the capacitor's stringent requirements for insulation strength and temperature resistance. To ensure sealing and insulation, the insulation layers of film capacitor leads have an extremely high degree of bonding with the internal fine conductors, and some high-temperature resistant insulation layers possess characteristics of high toughness and a low coefficient of friction.

[0003] When processing capacitor cables, the insulation layer of traditional wire stripper heads needs to be tightly bonded to the internal multi-strand fine wires to ensure insulation performance. The simple cutting action of the upper and lower blades alone is not enough to completely separate the insulation layer from the wires, which can easily lead to local adhesion residue of the insulation layer or curling of the edges after stripping, resulting in incomplete exposure of the conductor at the end of the lead wire. Therefore, a multi-core cable stripper head structure is proposed to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to provide a multi-core cable stripper head structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a multi-core cable stripper head structure, including a housing, with an upper cutter head and a lower cutter head slidably connected to the inner wall of the housing, and a rubbing mechanism provided on the upper cutter head, the rubbing mechanism including an upper rubbing plate and a lower rubbing plate, the upper rubbing plate being disposed on the upper cutter head, and the lower rubbing plate being disposed on the lower cutter head.

[0006] Preferably, a fixing rod is fixedly connected to the back of the upper cutter head, a connecting rod is slidably connected to the inner wall of the fixing rod, the bottom of the connecting rod is fixedly connected to the top of the upper washboard, a limit block is provided on the connecting rod, and the limit block is slidably connected to the top and bottom of the fixing rod.

[0007] Preferably, a first round rod is provided on the upper rubbing plate, a second round rod is provided on the lower rubbing plate, a first cylinder is provided on the lower cutter head, and a movable plate is fixedly connected to the output end of the first cylinder, and the movable plate is fixedly connected to the second round rod.

[0008] Preferably, the lower cutter head is provided with a swing frame, the inner wall of the swing frame is slidably connected to the second round rod, and the top of the swing frame is provided with an opening.

[0009] Preferably, the lower cutter head is provided with an adjustment mechanism, the adjustment mechanism including a second cylinder, the second cylinder is installed on the lower cutter head, a pressure sensor is installed on the top of the output end of the second cylinder, a middle block is provided on the top of the pressure sensor, and a sliding groove is opened at the bottom of the lower rubbing plate, and the sliding groove is slidably connected to the top of the middle block.

[0010] Preferably, the housing is rotatably connected to a rotating shaft, the outer wall of the rotating shaft is fixedly fitted with a gear, the upper cutter head is fixedly connected to a gear frame and meshes with the gear, and the lower cutter head is provided with a rack and meshes with the gear.

[0011] The present invention adopts the above technical solution, which can bring the following beneficial effects: 1. The multi-core cable stripper head structure is provided by setting up a rubbing mechanism composed of an upper rubbing plate and a lower rubbing plate. On the basis of the cutting head, a reverse rubbing action is added. The upper rubbing plate achieves stable translation through the sliding cooperation of the connecting rod and the fixed rod, while the lower rubbing plate ensures accurate rubbing trajectory through the cooperation of the middle block and the sliding groove. The synergistic effect of the two can ensure that the end edge of the stripped insulation layer is flat and burr-free. It can effectively separate the insulation layer that is tightly attached to the thin wire in the capacitor cable, avoid insulation layer residue or uneven edges, and ensure that the conductor at the end of the lead wire is completely exposed.

[0012] 2. The multi-core cable stripper head structure is achieved by a first cylinder driving a moving plate to move a second round rod, and then by a swing frame driving the first and second round rods to move in opposite directions, thereby realizing the reverse movement of the upper and lower stripping plates. Combined with the opening design of the swing frame, it can flexibly adapt to the stripping requirements of capacitor cables of different diameters, avoid stripping failure caused by differences in cable specifications, and improve the equipment's compatibility with multi-specification leads.

[0013] 3. The multi-core cable stripper head structure has a pressure sensor in the adjustment mechanism that can monitor the contact pressure between the upper and lower rubbing plates and the cable in real time. The height of the middle block is dynamically adjusted by the second cylinder to ensure that the rubbing force is always within the optimal range. This prevents the upper and lower rubbing plates from slipping due to insufficient pressure or tearing of the insulation layer due to excessive pressure, further ensuring the stability of the stripping quality.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-7 One embodiment of this utility model is as follows: a multi-core cable stripper head structure, including a housing 1, an upper cutter head 2 and a lower cutter head 3 are provided on the housing 1, and the opposing surfaces of the upper cutter head 2 and the lower cutter head 3 are in contact with each other. Limiting grooves are formed on both sides of the inner wall of the housing 1, and limiting strips are provided on both sides of the upper cutter head 2 and the lower cutter head 3, and the limiting strips are slidably connected to the inner wall of the limiting grooves. By setting the limiting grooves and limiting strips, the upper cutter head 2 and the lower cutter head 3 are stably vertically raised and lowered. A rotating shaft 6 is rotatably connected inside the housing 1, and a gear 7 is fixedly sleeved on the outer wall of the rotating shaft 6. A gear frame 8 is fixedly connected to the upper cutter head 2, and the gear frame 8 meshes with the gear 7. A rack 9 is provided on the lower cutter head 3, and the rack 9 meshes with the gear 7. The teeth of the gear frame 8 and the teeth on the rack 9 are respectively located on both sides of the gear 7, so that the gear 7 can drive the gear frame 8 and the rack 9 to move in opposite directions. A rotating shaft 6 is provided for connection with an external drive component, thereby driving the gear 7 to rotate. By setting the gear 7, gear frame 8 and rack 9, it is easy to drive the relative movement of the upper cutter head 2 and the lower cutter head 3 to strip the cable. A twisting mechanism 4 is provided on the upper cutter head 2.

[0018] The rubbing mechanism 4 includes an upper rubbing plate 43 and a lower rubbing plate 45. The upper rubbing plate 43 is mounted on the upper cutter head 2, and the lower rubbing plate 45 is mounted on the lower cutter head 3. A fixed rod 41 is fixedly connected to the back of the upper cutter head 2, and a connecting rod 42 is slidably connected to the inner wall of the fixed rod 41. The bottom of the connecting rod 42 is fixedly connected to the top of the upper rubbing plate 43. Two limit blocks are provided on the connecting rod 42. The two limit blocks are located above and below the fixed rod 41, respectively, and are slidably connected to the top and bottom of the fixed rod 41. The limit blocks are used to control the connecting rod 42. The upper rubbing plate 43 is restricted to move horizontally on the upper cutter head 2. A first round rod 44 is provided on the upper rubbing plate 43, and a second round rod 46 is provided on the lower rubbing plate 45. A first cylinder 47 is provided on the lower cutter head 3. A moving plate 48 is fixedly connected to the output end of the first cylinder 47, and the moving plate 48 is fixedly connected to the second round rod 46. A swing frame 49 is provided on the lower cutter head 3. The inner wall of the swing frame 49 is slidably connected to the second round rod 46. An opening is provided at the top of the swing frame 49. By setting the swing frame 49, the first round rod 44 can be driven to move in the opposite direction when the second round rod 46 moves.

[0019] Working principle: The multi-core cable is placed between the upper cutter head 2 and the lower cutter head 3. The external drive component drives the rotating shaft 6 to rotate. The rotation of the rotating shaft 6 drives the gear 7 to rotate. The rotation of the gear 7 drives the upper cutter head 2 to move downward through the gear frame 8. At the same time, the rotation of the gear 7 drives the lower cutter head 3 to move upward through the rack 9. This achieves the relative movement of the upper cutter head 2 and the lower cutter head 3, thereby performing the stripping operation on the multi-core cable.

[0020] When the upper cutter head 2 descends, the first round rod 44 on the upper cutter head 2 will enter the swing frame 49 through the opening of the swing frame 49. At this time, by activating the first cylinder 47, the first cylinder 47 drives the moving plate 48 to move, thereby driving the second round rod 46 to move horizontally. The horizontal movement of the second round rod 46 will drive the swing frame 49 to swing, and then the swing frame 49 will drive the first round rod 44 and the second round rod 46 to move in opposite directions, thereby realizing the opposite movement of the upper rubbing plate 43 and the lower rubbing plate 45 to rub the cable and assist the upper cutter head 2 and the lower cutter head 3 in stripping the cable.

[0021] Please see Figure 1-7 Based on the above embodiments, in another embodiment of the present invention, the lower cutter head 3 is provided with an adjustment mechanism 5. The adjustment mechanism 5 includes a second cylinder 51, which is installed on the lower cutter head 3. A pressure sensor 52 is installed on the top of the output end of the second cylinder 51. A middle block 53 is provided on the top of the pressure sensor 52. A sliding groove 54 is provided on the bottom of the lower rubbing plate 45, and the sliding groove 54 is slidably connected to the top of the middle block 53.

[0022] Working principle: The second cylinder 51 is activated to move the pressure sensor 52. The movement of the pressure sensor 52 will move the lower wash plate 45 through the middle block 53, making contact with the cable. The pressure sensor 52 senses the pressure value between the lower wash plate 45 and the cable, so as to avoid the friction between the upper wash plate 43 and the lower wash plate 45 and the cable being too small and affecting the washing effect, making the washing of the cable by the upper wash plate 43 and the lower wash plate 45 more stable.

[0023] This utility model provides a multi-core cable stripper head structure. There are many methods and approaches to implement this technical solution. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
