Description

Technical Field

[0001] This utility model relates to the field of cable manufacturing technology, specifically to a cutting device for flat shielded cables and its cable structure. Background Technology

[0002] Cables are a common conductor type used in the automotive industry and many other industrial sectors, and are frequently used in new energy commercial vehicles, passenger cars, charging piles, and energy storage equipment. The copper conductors in cables are commonly made of copper or aluminum, and the most common construction method involves a surface coating of insulating material.

[0003] The production of cables involves several processes, including metal raw material smelting, wire drawing, insulation processing, cabling, and winding and packaging. Since cables are produced continuously on the production line, the packaging process begins by winding the cable into a coil on a winding machine. Once the coil reaches a certain length, it is cut. Finally, the resulting cable coil is wrapped or laminated to complete the cable product manufacturing process.

[0004] However, the cutting process is located before the winding and packaging process to cut the continuous cable into cable rolls of suitable length. Since the cable moves along the axial direction of the cable roll during winding, its axial position relative to the roll is arbitrary after reaching the preset length. Therefore, when cutting, the length of the cutter needs to cover the cable's movement range, requiring a long cutter design, which wastes material.

[0005] Therefore, the applicant has developed a new technical solution in the actual production process to solve the above-mentioned technical problems. Utility Model Content

[0006] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a cutting device for flat shielded cables and its cable structure, which has the advantage that the cable can be cut without the need for a designed-length cutter after it has been wound to a preset length.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] This utility model provides a cutting device for flat shielded cables and its cable structure, including a cutting table located on the ground and on one side of a winding roller. The length of the cutting table is distributed along the length direction of the winding roller, and the lengths of the winding roller and the cutting table are distributed along the horizontal direction. The cutting table is provided with an adjusting member that allows the cable to reciprocate along the length direction of the winding roller, and the adjusting member is provided with a cutting member.

[0009] By adopting the above technical solution, the cable is wound on the winding roller. As the winding roller rotates, the cable is gradually wound onto the winding roller. The adjusting component moves the cable from one end of the winding roller to the other end, making it easier for the cable to be wound axially on the winding roller. The cutting component is set on the adjusting component, so that the cutting component moves with the cable. When the cable is wound to the preset length, since the cutting component moves with the cable, when it is necessary to cut the cable, the cutting component only needs to work to cut the cable.

[0010] Preferably, the adjusting component includes vertical plates disposed at both ends of the cutting table along its length, the two vertical plates being connected by a lead screw, a movable block passing through the lead screw, the movable block being threadedly connected to the lead screw, the lower end of the movable block being slidably connected to the upper surface of the cutting table, the two ends of the lead screw being rotatably connected to the two vertical plates respectively, one of the vertical plates being provided with a motor for driving the lead screw to rotate, and the movable block being provided with a limiting component for the cable to pass through and for limiting the position of the cable.

[0011] Preferably, the limiting component includes two opposing elongated adjustment frames rotatably connected to the upper end of the moving block. The length direction of the adjustment frames is distributed vertically. A horizontal roller is rotatably connected inside the adjustment frame. The moving block has two vertically distributed limiting rollers in a pair rotatably connected on the side of the horizontal roller away from the winding roller. The cable passes between the two limiting rollers and abuts against the horizontal roller. The moving block is provided with two pairs of limiting rollers, and there is a gap between the two pairs of limiting rollers. The cutting component is located between the two pairs of limiting rollers.

[0012] Preferably, the cutting component includes a placement groove formed on the upper end face of the moving block and located between two pairs of limiting rollers. The length direction of the placement groove is distributed parallel to the length direction of the horizontal roller. The bottom of the placement groove is slidably connected to two opposing racks, which are meshed by a gear. The bottom of the placement groove is provided with a motor that drives the gear to rotate. Each of the two racks has a mounting plate extending out of the groove opening at one of their opposite ends. One of the mounting plates is provided with a cutter, and the other mounting plate has a cutting slit through which the cutter passes.

[0013] Preferably, the movable block has two sliding grooves parallel to the placement groove. The longitudinal section of the sliding groove is a dovetail groove. Each sliding groove has a slider corresponding to the limiting roller that slides through it. Each slider has a threaded rod extending out of the sliding groove at its upper end. The bottom of each limiting roller is rotatably connected to the upper end of the corresponding threaded rod. Each threaded rod has a pressure ring threadedly connected to its outer wall that abuts against the upper surface of the movable block.

[0014] Preferably, both ends of the horizontal roller are rotatably connected to sliding columns that slide within the inner wall of the adjustment frame. The ends of the two sliding columns that are away from the horizontal roller extend out of the adjustment frame, and each of the extended ends is threadedly connected to a limiting block that abuts against the side wall of the adjustment frame.

[0015] Preferably, the upper end of the adjusting frame is rotatably connected to a stop roller parallel to the horizontal roller.

[0016] Another object of the present invention is to provide a flat shielded cable, comprising a conductor layer with a flat cross-section, an insulation layer, a shielding layer and a protective layer sequentially covering the conductor layer; the shielding layer is a braided metal mesh layer and / or an aluminum foil layer.

[0017] The beneficial effects of this utility model are as follows: the cable is wound on the winding roller, and as the winding roller rotates, the cable is gradually wound onto the winding roller. The adjusting component moves the cable from one end of the winding roller to the other end, making it easier for the cable to be wound axially on the winding roller. The cutting component is set on the adjusting component, so that the cutting component moves with the cable. When the cable is wound to a preset length, since the cutting component moves with the cable, when it is necessary to cut the cable, the cutting component only needs to work to cut the cable.

[0025] 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.

[0026] Example 1: A cutting device for a flat shielded cable and its cable structure, such as Figure 1 and Figure 2 It includes a cutting table 11 located on one side of the winding roller 1 and on the ground. The winding roller 1 is horizontally distributed for winding cables and is an existing type. The length of the cutting table 11 is distributed along the length direction of the winding roller 1. The lengths of the winding roller 1 and the cutting table 11 are distributed along the horizontal direction. The cutting table 11 is provided with an adjusting member that causes the cable to reciprocate along the length direction of the winding roller 1. The adjusting member is provided with a cutting member.

[0027] like Figure 1 and Figure 2 The cable is wound on the winding roller 1. As the winding roller 1 rotates, the cable is gradually wound onto the winding roller 1. The adjusting component moves the cable from one end of the winding roller 1 to the other end, making it easier for the cable to be wound axially on the winding roller 1. The cutting component is set on the adjusting component, so that the cutting component moves with the cable. When the cable is wound to the preset length, since the cutting component moves with the cable, when it is necessary to cut the cable, the cutting component only needs to work to cut the cable.

[0028] like Figure 1 and Figure 2The adjusting component includes two vertical plates 12 disposed at both ends of the cutting table 11 along its length. The two vertical plates 12 are connected by a lead screw 121. A movable block 122 passes through the lead screw 121 and is threadedly connected to the lead screw 121. The lower end of the movable block 122 is slidably connected to the upper surface of the cutting table 11. The two ends of the lead screw 121 are rotatably connected to the two vertical plates 12 respectively. One of the vertical plates 12 is provided with a motor 123 that drives the lead screw 121 to rotate. The movable block 122 is provided with a limiting component that allows the cable to pass through and restricts the position of the cable.

[0029] like Figure 1 and Figure 2 The motor 123 drives the lead screw 121 to rotate, which causes the lead screw 121 to drive the moving block 122 to move back and forth on the cutting table 11. This facilitates the moving block 122 to drive the limiting member to move back and forth, so that the cable moves back and forth along the axial direction of the winding roller 1 as it winds the winding roller 1.

[0030] like Figure 1 and Figure 2 The limiting component includes two opposing elongated adjustment frames 124 rotatably connected to the upper end of the moving block 122. The length direction of the adjustment frames 124 is vertically distributed. A horizontal roller 125 is rotatably connected inside the adjustment frame 124. Two vertically distributed limit rollers 126 are rotatably connected to the side of the moving block 122 opposite to the winding roller 1. The cable passes between the two limit rollers 126, abuts against the horizontal roller 125, and then winds around the winding roller 1. The moving block 122 is provided with two pairs of limit rollers 126, and there is a gap between the two pairs of limit rollers 126. The cutting component is located between the two pairs of limit rollers 126. The two pairs of limit rollers 126 facilitate the movement of the cable with the movement of the moving block 122. The setting of the horizontal roller 125 facilitates the cable to reduce contact with the moving block 122 after passing through the two pairs of limit rollers 126, and is then guided to the winding roller 1.

[0031] like Figure 1 and Figure 2The cutting component includes a placement groove 13 located on the upper surface of the moving block 122 and between two pairs of limiting rollers 126. The placement groove 13 is located in the gap between the two pairs of limiting rollers 126. The length direction of the placement groove 13 is distributed parallel to the length direction of the horizontal roller 125. Two opposing racks 131 are slidably connected to the bottom of the placement groove 13. The two racks 131 are meshed by a gear 132. The two racks 131 are located on both sides of the gear 132 and their length direction is parallel to the length direction of the placement groove 13. The bottom of the placement groove 13 is provided with a motor 133 that drives the gear 132 to rotate. At this time, a groove for placing the motor 133 can be opened in the bottom of the placement groove 13. The gear 132 is coaxially mounted on the rotating shaft of the motor 133. At the ends of the two racks 131 that are far apart from each other, there are mounting plates 134 extending out of the groove opening of the placement groove 13. One mounting plate 134 is provided with a cutter 135, and the other mounting plate 134 is provided with a cutting slit 136 for the cutter 135 to pass through.

[0032] like Figure 1 and Figure 2 The cutting principle of the cutting component is as follows: After the cable is wound to a preset length, it is positioned between two pairs of limiting rollers 126. At this time, the motor 133 drives the gear 132 to rotate, causing the racks 131 at both ends of the gear 132 to move the two mounting plates 134 closer together until the cutter 135 limits the cable between the cutter 135 and the other mounting plate 134. As the cutter 135 moves towards the slit 136, it cuts the cable when its blade enters the slit 136. The length of the cutter 135 only needs to be greater than the outer diameter of the cable, achieving the goal of cutting the cable even after it has been wound to the preset length, without requiring a designed length. When the cable is being transmitted normally, the gear 132 drives the two mounting plates 134 on the racks 131 to move away from each other, causing the cutter 135 to move away from the cable distribution, awaiting the next cut.

[0033] like Figure 2 and Figure 3 The movable block 122 has two sliding grooves 14 parallel to the placement groove 13. Both ends of the sliding grooves 14 extend out of both ends of the movable block 122. The longitudinal section of the sliding grooves 14 is a dovetail groove. Each sliding groove 14 has a slider 141 corresponding to the limiting roller 126 that is slidably connected. Each slider 141 has a threaded rod 142 extending out of the sliding groove 14 at its upper end. The bottom of each limiting roller 126 is rotatably connected to the upper end of the corresponding threaded rod 142. Each threaded rod 142 has a pressure ring 143 that abuts against the upper end face of the movable block 122.

[0034] like Figure 2 and Figure 3When it is necessary to adjust the distance between the two limiting rollers 126 to accommodate cables of different outer diameters, the pressure ring 143 is rotated away from the moving block 122, and the position of the limiting roller 126 is changed by the threaded rod 142 and the slider 141. When it is necessary to fix the position of the limiting roller 126, the pressure ring 143 is rotated, and the pressure ring 143 is pressed against the upper end face of the moving block 122, which restricts the position of the slider 141, and thus restricts the position of the limiting roller 126.

[0035] like Figure 2 and Figure 3 Both ends of the horizontal roller 125 are rotatably connected to sliding columns 15 that slide on the inner wall of the adjusting frame 124. The ends of the two sliding columns 15 opposite to the horizontal roller 125 extend out of the adjusting frame 124, and each extended end is threadedly connected to a limiting block 151 that abuts against the side wall of the adjusting frame 124. At this time, both ends of the horizontal roller 125 are rotatably connected to the sliding columns 15, facilitating cable transmission. When the height of the horizontal roller 125 needs to be adjusted, the limiting block 151 is rotated away from the adjusting frame 124, and the horizontal roller 125 is moved up and down, causing the sliding columns 15 to slide on the inner wall of the adjusting frame 124. When the horizontal roller 125 moves to the appropriate position, the limiting block 151 is rotated to a position that abuts against the side wall of the adjusting frame 124, restricting the position of the sliding columns 15, and thus restricting the position of the horizontal roller 125.

[0036] like Figure 2 and Figure 3 The upper end of the adjusting frame 124 is rotatably connected to a stop roller 16 parallel to the horizontal roller 125. The stop roller 16 is set to restrict the cable from gradually separating from the horizontal roller 125 as it gets thicker and thicker on the winding roller 1. The stop roller 16 is the highest position that restricts the cable from moving away from the horizontal roller 125, which makes it easier for the cable to still be transmitted between the two pairs of limit rollers 126.

[0037] Example 2: A flat shielded cable, such as Figure 4 The cable includes a flat-section conductor layer 2. This flattened structure is more suitable for integration with the vehicle body. The flattened conductor shape can be easily manufactured semi-automatically or automatically using specific flat-mouth molds and tooling, adapting to different production needs. The flat-shielded cable also includes an insulation layer 21, a shielding layer 22, and a protective layer 23 sequentially wrapped around the conductor layer 2. The shielding layer 22 is a braided metal mesh layer and / or an aluminum foil layer. The metal mesh layer can withstand repeated bending, improving the cable's bending performance, while the aluminum foil layer provides high coverage over the insulation layer 21, eliminating electromagnetic leakage points. The insulation layer 21 is made of plastic particles with high temperature resistance and high insulation. The protective layer 23 can be a plastic material meeting different temperature resistance requirements, effectively reducing the risk of friction damage to the shielding layer 22 under vibration.

[0038] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
