Description

Technical Field

[0001] This utility model relates to the field of wire breakage sensing technology, specifically a wire breakage sensing device for a stranding machine. Background Technology

[0002] A stranding machine is a mechanical device used to strand multiple single-strand metal wires (such as copper wire, aluminum wire, etc.) together. During the stranding process, the wires to be stranded may break due to their own quality or the speed of stranding. To avoid product quality problems or equipment damage caused by wire breakage, it is often necessary to use a wire breakage detection device for monitoring.

[0003] Patent CN208061730U discloses a wire breakage detection device for a stranding machine. The device includes a base with a mounting block. A wire to be stranded passes through the mounting block into the stranding machine. A sensing element is vertically slidably connected to the mounting block, with its upper end suspended from the wire to be stranded. An infrared sensor is mounted on the base, located directly below the sensing element. When the wire breaks, the sensing element falls, triggering the infrared sensor, which outputs a trigger signal. A controller is mounted on the stranding machine, electrically connected to the infrared sensor. The controller receives the trigger signal and, upon receiving it, controls the stranding machine's drive motor to stop. The sensing element amplifies the wire breakage phenomenon, making it easier for the infrared sensor to detect, thus improving the sensitivity of the wire breakage detection device.

[0004] However, the above-mentioned detection device still has the following problems in actual use:

[0005] During the stranding process, each wire is under tension. If a wire breaks, the internal tension is released instantly, causing the broken wire to lose its restraint and bounce or fly off. During this process, the broken wire may collide with or interfere with other running wires, which not only exacerbates the bouncing but may also cause other wires to break subsequently, further impacting production efficiency and product quality. However, while current wire breakage detection devices can detect wire breaks, they lack the ability to effectively protect or shield the broken wire, a deficiency that causes inconvenience in practical operation. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a wire breakage sensing device for a stranding machine, which can clamp the broken wire at the same time as it breaks, preventing the wire from bouncing or flying out.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a wire breakage sensing device for a stranding machine, comprising two support columns mounted on the stranding machine, with a support assembly and two wire rings connected to the ends of the two support columns away from the stranding machine, the support assembly located in the middle of the two wire rings, and eight wire openings penetrating the surface of each of the two wire rings, with a monitoring mechanism connected to the inner wall of each of the eight wire openings, a lifting mechanism connected to the end of the support assembly away from the two support columns, and eight pressing components connected to the output end of the lifting mechanism, with the two ends of the eight pressing components respectively connected to the side adjacent to the two wire rings, and the eight pressing components respectively matching and aligning with the eight wire openings.

[0008] Furthermore, the support assembly includes a horizontal plate and two support blocks. The lower ends of the two support blocks are respectively sleeved and fixedly connected to the outer walls of the two support columns, and the upper ends of the two support blocks are respectively fixedly connected to the two ends of the horizontal plate. The horizontal plate is located above the eight extrusion components, and the middle part of the horizontal plate is connected to the lifting mechanism.

[0009] Furthermore, the lifting mechanism includes an electric actuator, a connecting plate, a lifting plate, and seven lifting rods. The outer wall of the electric actuator is fixedly connected to the middle of the upper surface of the horizontal plate. The output end of the electric actuator passes through the horizontal plate and is fixedly connected to the middle of the lifting plate. The bottom surface of the lifting plate is connected to one of the extrusion components. The two ends of the connecting plate are connected to the side walls of the other two extrusion components. The bottom surface of the connecting plate is fixedly connected to the upper end of one of the lifting rods. The lower end of the lifting rod is connected to the fourth extrusion component. The outer walls of the other six lifting rods are slidably connected to the outer wall of the horizontal plate. The upper ends of these six lifting rods are fixedly connected to the lifting plate. The lower ends of four of these six lifting rods are respectively connected to the remaining four extrusion components. The lower ends of the last two lifting rods are respectively fixedly connected to the two sides of the upper surface of the connecting plate.

[0010] Furthermore, the monitoring mechanism includes a slider, a fixed block, and an infrared sensor. The inner wall of the upper surface of the slider is fixedly connected to the outer wall of the infrared sensor. The bottom surface of the slider is matched and aligned with the fixed block. The outer wall of the slider is slidably connected to the inner wall of the wire opening. The outer wall of the fixed block is fixedly connected to the inner wall of the wire opening. The side wall of the fixed block is connected to the extrusion assembly.

[0011] Furthermore, the extrusion assembly includes connecting strips, an upper arc plate, and a lower arc plate. The end of the lower arc plate is fixedly connected to the side wall of the fixed block. The upper and lower arc plates are matched and aligned. The upper surface of the upper arc plate is fixedly connected to the bottom surface of the connecting strips. The eight connecting strips are respectively fixedly connected to the output end of the electric actuator, both ends of the connecting plate, and five lifting rods.

[0012] Furthermore, several upper blocks are fixedly connected to both sides of the upper arc plate, and several lower blocks are fixedly connected to both sides of the lower arc plate. Guide rods are fixedly connected to the inner walls of the lower blocks, and the outer walls of the upper ends of the guide rods are slidably connected to the inner walls of the upper blocks.

[0013] Furthermore, connecting blocks are fixedly connected to both sides of the outer wall of the conductor ring, and the two connecting blocks are respectively sleeved and fixedly connected to the outer walls of the two support columns.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The wire breakage sensing device of this type of stranding machine is made by setting two wire loops between two support columns and setting a monitoring mechanism in the wire opening of each of the two wire loops. When one of the strands breaks, it can be detected immediately, which is convenient and quick.

[0016] 2. The wire breakage sensing device of this type of stranding machine is configured by setting a support component between two support columns, and setting a lifting mechanism and a squeezing component on the support component. When the monitoring mechanism detects that the strand is broken, the squeezing component can be lowered by the lifting mechanism, so that the broken and unbroken strands can be clamped at the same time. This not only avoids the bounce and shaking of the broken strands, but also protects the unbroken strands. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 1-5 A wire breakage sensing device for a stranding machine includes two support columns 1 mounted on the stranding machine. The ends of the two support columns 1 away from the stranding machine are connected to a support assembly and two wire rings 9. The support assembly is located in the middle of the two wire rings 9. Eight wire openings 18 are opened through the surface of each of the two wire rings 9. A monitoring mechanism is connected to the inner wall of each of the eight wire openings 18. The end of the support assembly away from the two support columns 1 is connected to a lifting mechanism. The output end of the lifting mechanism is connected to eight compression components. The two ends of the eight compression components are respectively connected to the side adjacent to the two wire rings 9, and the eight compression components are respectively matched and aligned with the eight wire openings 18.

[0025] like Figures 1 to 5 As shown, when using the wire breakage sensing device of the stranding machine in this utility model, firstly, the eight wires to be stranded are passed through the eight wire openings 18 of the two wire rings 9 respectively, and then through the eight extrusion components respectively. Subsequently, all eight wires to be stranded are connected to the stranding machine for conventional stranding.

[0026] During normal stranding, eight monitoring mechanisms are connected and supported by eight strands. When one strand breaks, it loses its tension and support and will fall instantly under the gravity of the monitoring mechanism. As it falls, the monitoring mechanism immediately transmits an electrical signal to an external processor, which then shuts down the stranding machine and activates the lifting mechanism. Once activated, the lifting mechanism pushes the eight extrusion components simultaneously, thus limiting the eight strands and preventing the wire from bouncing or flying out.

[0027] It is important to note here that:

[0028] 1. The wire breakage sensing device for a stranding machine in this utility model is similar in structure to the existing wire breakage sensing device for a stranding machine, such as the wire breakage detection device for a stranding machine disclosed in patent publication number CN208061730U. The positional relationship and connection relationship between the support column 1 and the stranding machine are all prior art disclosed in the prior art documents, and will not be described in detail here.

[0029] 2. The quantities mentioned above, such as the two conductor rings 9, the eight conductor ports 18, and the eight extrusion components, are only for the convenience of description and understanding, and do not limit the actual quantity. The specific quantity can be selected according to the actual number of stranded wires, corresponding to the number of conductor rings 9 with conductor ports 18.

[0030] Please refer to the main text. Figure 1 and Figure 2The support assembly includes a horizontal plate 3 and two support blocks 2. The lower ends of the two support blocks 2 are respectively sleeved and fixedly connected to the outer walls of the two support columns 1. The upper ends of the two support blocks 2 are respectively fixedly connected to the two ends of the horizontal plate 3. The horizontal plate 3 is located above the eight extrusion components, and the middle part of the horizontal plate 3 is connected to the lifting mechanism.

[0031] More specifically, by setting up a horizontal plate 3 and two support blocks 2, not only can the lifting mechanism be supported, but also, because the lifting mechanism is supported above the extrusion components, the lifting mechanism can be prevented from obstructing the eight extrusion components.

[0032] Please refer to the main text. Figure 1 and Figure 2 The mechanism includes an electric actuator 4, a connecting plate 13, a lifting plate 19, and seven lifting rods 5. The outer wall of the electric actuator 4 is fixedly connected to the middle of the upper surface of the horizontal plate 3. The output end of the electric actuator 4 passes through the horizontal plate 3 and is fixedly connected to the middle of the lifting plate 19. The bottom surface of the lifting plate 19 is connected to one of the extrusion components. The two ends of the connecting plate 13 are connected to the side walls of the other two extrusion components. The bottom surface of the connecting plate 13 is fixedly connected to the upper end of one of the lifting rods 5. The lower end of the lifting rod 5 is connected to the fourth extrusion component. The outer walls of the other six lifting rods 5 are slidably connected to the outer wall of the horizontal plate 3. The upper ends of the six lifting rods 5 are fixedly connected to the lifting plate 19. The lower ends of four of the six lifting rods 5 are respectively connected to the remaining four extrusion components. The lower ends of the last two lifting rods 5 are respectively fixedly connected to the two sides of the upper surface of the connecting plate 13.

[0033] More specifically, when it is necessary to control the clamping of the stranded wires by the extrusion assembly, simply turn on the electric push rod 4. After the electric push rod 4 is activated, it will instantly push the lifting plate 19 down. After the lifting plate 19 descends, it will bring down the six lifting rods 5 at the top. The lifting plate 19 will also push the connecting plate 13 up and down through two of the lifting rods 5. Then the connecting plate 13 will push the last of the seven lifting rods 5 down. In this way, all eight extrusion assemblies can be lowered at the same time, thus clamping all eight stranded wires together. This not only avoids the ejection and shaking of broken stranded wires, but also protects the unbroken stranded wires.

[0034] Please refer to the main text. Figures 1-3 and Figure 5 The monitoring mechanism includes a slider 10, a fixed block 11, and an infrared sensor 17. The inner wall of the upper surface of the slider 10 is fixedly connected to the outer wall of the infrared sensor 17. The bottom surface of the slider 10 is matched and aligned with the fixed block 11. The outer wall of the slider 10 is slidably connected to the inner wall of the wire opening 18. The outer wall of the fixed block 11 is fixedly connected to the inner wall of the wire opening 18. The side wall of the fixed block 11 is connected to the extrusion assembly.

[0035] More specifically, during normal use, because the stranded wire is taut, the slider 10 and the infrared sensor 17 are positioned above the wire opening 18, supported by the stranded wire. When the stranded wire breaks, the slider 10 and the infrared sensor 17 lose their supporting force and will slide down instantly due to gravity. After the infrared sensor 17 slides down, the distance between the transmitting and receiving ends of the infrared sensor 17 changes, thereby immediately transmitting an electrical signal to the outside, and activating the electric actuator 4 via the external controller.

[0036] Please refer to the main text. Figure 1 and Figure 3 The extrusion assembly includes a connecting strip 6, an upper arc plate 7, and a lower arc plate 8. The end of the lower arc plate 8 is fixedly connected to the side wall of the fixing block 11. The upper arc plate 7 and the lower arc plate 8 are matched and aligned. The upper surface of the upper arc plate 7 is fixedly connected to the bottom surface of the connecting strip 6. The eight connecting strips 6 are respectively fixedly connected to the output end of the electric push rod 4, the two ends of the connecting plate 13, and the five lifting rods 5.

[0037] More specifically, when the electric actuator 4 is activated, the connecting plate 13 and the six lifting rods 5 will simultaneously push the connecting bar 6 down. After the connecting bar 6 descends, it will push the upper arc plate 7 down as well. After the upper arc plate 7 descends, it can cooperate with the lower arc plate 8 to clamp the stranded wire from both ends.

[0038] It should be noted that during normal use, the stranded wire rests on the curved surface of the lower arc plate 8 (of course, the stranded wire is in a taut state). When one of the stranded wires breaks, the upper arc plate 7 descends, which can cooperate with the lower arc plate 8 to clamp the stranded wire.

[0039] Please refer to the main text. Figure 3 and Figure 4 Several upper blocks 15 are fixedly connected to both sides of the upper arc plate 7, and several lower blocks 14 are fixedly connected to both sides of the lower arc plate 8. Guide rods 16 are fixedly connected to the inner walls of the several lower blocks 14, and the outer walls of the upper ends of the several guide rods 16 are slidably connected to the inner walls of the several upper blocks 15 respectively.

[0040] More specifically, by setting up the upper block 15, the lower block 14 and the guide rod 16, not only can the connection between the upper arc plate 7 and the lower arc plate 8 be increased, but the deviation of the upper arc plate 7 when it descends can also be prevented.

[0041] Please refer to the main text. Figures 1-3 and Figure 5 Both sides of the outer wall of the conductor ring 9 are fixedly connected to the connecting blocks 12, and the two connecting blocks 12 are respectively sleeved and fixedly connected to the outer walls of the two support columns 1.

[0042] More specifically, by setting the connecting block 12, the connection stability between the conductor ring 9 and the support column 1 can be increased.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
