Description

Technical Field

[0001] The utility model relates to the technical field of wire twisting machines, and more particularly to a wire twisting machine with a function of preventing wire breakage. Background Art

[0002] A cable twister is a device used to twist multiple wires, cables, or conductors together. Using a rotating capstan or cage, the twister twists individual wires or strands of wire around a central axis and twists them together. Breakage of individual wires or conductors during the twisting process can damage the product, requiring re-twisting or rendering it scrapped.

[0003] Currently, in actual production applications, to effectively prevent single conductor breakage during cable stranding machine operation, comprehensive and professional training is commonly employed for cable stranding machine operators. Through systematic training, operators gain a thorough understanding of the equipment's specific operating procedures, including its working principles, operating parameters, and performance under different conditions. Safety precautions are also crucial, minimizing the risk of conductor breakage caused by improper operation. Furthermore, rigorous sampling inspection of each batch of purchased conductors is crucial. The conductors are carefully inspected for damage, such as scratches, dents, and rust. Such conductors are more susceptible to breakage during the stranding process, while rust reduces the conductor's electrical conductivity and mechanical strength, impacting the overall quality of the cable. However, there are few measures to monitor the stranding process in real time to prevent breakage. This is a significant shortcoming. Without timely detection and control, wire breakage during the stranding process can not only impact production schedules but also lead to waste of raw materials and increased costs.

[0004] Therefore, a stranding machine with a wire breakage prevention function is proposed, which can realize process detection and control, reduce economic losses and improve maintenance efficiency. Utility Model Content

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a stranding machine with a wire breakage prevention function, which can realize process detection and control, reduce economic losses, and improve maintenance efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A wire twisting machine with a wire breakage prevention function comprises a base plate, a wire twisting assembly is provided at the top of the base plate, multiple groups of tensioning detection assemblies are provided on one side of the wire twisting assembly, two groups of wire pulleys are provided on the side of the tensioning detection assembly away from the wire twisting assembly, and a take-up disk is provided on the side of the wire pulley away from the tensioning detection assembly; the wire twisting assembly comprises a driving shaft, a driving gear is provided on the side of the driving shaft close to the tensioning detection assembly, a driven gear is meshed and connected with the driving gear on the side of the driving shaft away from the driving shaft, a driven gear is fixedly connected to the driven disk on the side of the driven gear away from the driving gear, a guide disk is fixedly connected to the side of the driven disk close to the tensioning detection assembly, multiple groups of sensor fixing blocks are provided on the side of the guide disk close to the tensioning detection assembly, and a circular sensor mounting hole is provided on the side of the sensor fixing block away from the driving shaft.

[0008] By adopting the above technical solution, the cable single line is passed through the threading hole opened on the guide disk to prevent the cable single line from running out of the specified track. The sensor installation hole opened on the sensor fixing block provides an installation environment for the detection equipment in the tensioning detection assembly. The detection equipment detects whether the cable single line is broken. If the line is broken, the entire equipment is stopped to avoid the need to rework the cable due to continued bundling after the line is broken, thereby reducing work loss time and improving maintenance efficiency.

[0009] The utility model is further configured as follows: a plurality of groups of single-line columns are provided on one side of the driven disk close to the tensioning detection component, and the number of the plurality of groups of single-line columns is consistent with that of the tensioning detection component; a plurality of groups of threading holes are provided on one side of the guide disk, and the number of the plurality of groups of threading holes is consistent with that of the single-line columns; and the number of the plurality of groups of sensor fixing blocks is consistent with that of the threading holes.

[0010] By adopting the above technical solution, an external motor drives the drive shaft to rotate the driving gear, which provides power to the driven gear, driving the driven disk to rotate. The single-wire column is fixed to the driven disk, so that multiple cable single wires can be twisted together, realizing the cable twisting function and improving the regularity and electrical performance of the cable.

[0011] The utility model is further configured as follows: the tension detection component includes a tension column, a circular latch hole is opened on one side of the tension column, a latch is plugged into the side of the tension column close to the latch hole, and the latch is adapted to the shape of the latch hole.

[0012] The utility model is further configured as follows: a proximity switch is provided at the center of the sensor installation hole, a plurality of sets of fixing nuts are provided along the center of the proximity switch, and a spring is provided at the top end of the sensor installation hole.

[0013] The utility model is further configured as follows: one end of the spring is fixedly connected to the sensor mounting hole, and the other end thereof is fixedly connected to the tension column, and two sets of fixed wheel blocks are provided on the top of the tension column.

[0014] The utility model is further configured as follows: a wheel hole is opened on one side of the fixed wheel block, a tension wheel is inserted between the two groups of fixed wheel blocks, and the tension wheel is adapted to the shape of the wheel hole.

[0015] By adopting this technical solution, a pin is inserted to install the tension column and guide disc together, allowing the tension column to rotate on the guide disc. The spring pulls the tension column, causing the lower end of the tension wheel to press against the cable wire, and the tension wheel is rotatably connected to the fixed wheel block. When the cable wire breaks, the spring contracts, pulling the tension column as a whole toward the center of the guide disc. The proximity switch, fixed by a fixing nut on the sensor fixing block, detects the tension column and transmits a signal to the device controller, which stops the motor driving the take-up reel and drive shaft, stopping the entire device. This achieves tension sensing and improves the efficiency of post-break repair.

[0016] In summary, this application includes at least one of the following beneficial technical effects:

[0017] 1. The wire threading hole on the guide plate is used to pass the single cable to prevent it from running out of the specified track. The sensor installation hole on the sensor fixing block provides an installation environment for the detection equipment in the tension detection assembly. The detection equipment detects whether the single cable is broken. If the cable is broken, the entire equipment will be stopped to avoid the need to rework the cable due to continued bundling after the break, thus reducing work delays and improving maintenance efficiency.

[0018] 2. The external motor drives the drive shaft to rotate the driving gear, which provides power to the driven gear, driving the driven disc to rotate. The single-wire column is fixed to the driven disc, so that multiple cable wires can be twisted together to realize the cable twisting function and improve the regularity and electrical performance of the cable.

[0019] 3. Plug the tension column and guide disc together, allowing the tension column to rotate on the guide disc. The spring pulls the tension column, causing the lower end of the tension wheel to press against the cable wire, and the tension wheel is rotatably connected to the fixed wheel block. When the cable wire breaks, the spring contracts, pulling the tension column toward the center of the guide disc. The proximity switch, fixed by a fixing nut on the sensor fixing block, detects the tension column and transmits a signal to the device controller, which stops the motor driving the take-up reel and drive shaft, stopping the entire device. This achieves tension sensing and improves the efficiency of repair after a break. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0032] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0033] For example 1, please refer to Figure 1-6 , the utility model provides the following technical solutions:

[0034] Specifically refers to a stranding machine with a function to prevent wire breakage, see Figure 1The device comprises a base plate 1, which provides an installation environment for other components. A stranding assembly 2 is provided on the top of the base plate 1, which realizes the stranding function through the stranding assembly 2 and provides an installation environment for some tension detection assemblies 3. Multiple sets of tension detection assemblies 3 are provided on one side of the stranding assembly 2. The tension detection assemblies 3 provide tension detection for each cable line. If a line breaks, the entire device stops, improving the efficiency of post-break maintenance. Two sets of wire pulleys 4 are provided on the side of the tension detection assembly 3 away from the stranding assembly 2. The wire pulleys 4 drive and transport the stranded cable. A take-up reel 5 is provided on the side of the wire pulley 4 away from the tension detection assembly 3, and the completed cable is bundled by the take-up reel 5.

[0035] See Figure 2-6 The stranding assembly 2 includes a drive shaft 21. A driving gear 22 is provided on the side of the drive shaft 21 near the tension detection assembly 3. A driven gear 23 is meshedly connected to the driving gear 22 on the side away from the drive shaft 21. A driven disc 24 is fixedly connected to the side of the driven gear 23 away from the driving gear 22. A guide disc 26 is fixedly connected to the side of the driven disc 24 near the tension detection assembly 3. Multiple sets of sensor fixing blocks 28 are provided on the side of the guide disc 26 near the tension detection assembly 3. Circular sensor mounting holes 29 are provided on the side of the sensor fixing blocks 28 away from the drive shaft 21. Multiple sets of single-wire posts 25 are provided on the side of the driven disc 24 near the tension detection assembly 3. The number of multiple sets of single-wire posts 25 is the same as that of the tension detection assembly 3. Multiple sets of threading holes 27 are provided on one side of the guide disc 26. The number of multiple threading holes 27 is the same as that of the single-wire posts 25. The number of multiple sets of sensor fixing blocks 28 is the same as that of the threading holes 27.

[0036] Specifically, the cable single wire is passed through the threading hole 27 opened on the guide disk 26 to prevent the cable single wire from running out of the specified track. The sensor installation hole 29 opened on the sensor fixing block 28 provides an installation environment for the detection equipment in the tension detection assembly 3. The detection equipment detects whether the cable single wire is broken. If the wire is broken, the entire equipment is stopped to avoid continuing to bundle the cable after the wire is broken, which causes the cable to need to be reworked, reducing work delays and improving maintenance efficiency. The external motor drives the drive shaft 21 to rotate the driving gear 22, and the driving gear 22 provides power to the driven gear 23, driving the driven disk 24 to rotate the single wire column 25 fixed to the driven disk 24, so that multiple cable single wires can be twisted, realizing the cable twisting function and improving the regularity and electrical performance of the cable.

[0037] See Figure 4-5The tension detection assembly 3 includes a tension column 31, a circular pin hole 36 is provided on one side of the tension column 31, a pin 32 is inserted into the side of the tension column 31 near the pin hole 36, and the pin 32 is adapted to the pin hole 36 in shape. A proximity switch 33 is provided in the center of the sensor mounting hole 29, and multiple groups of fixing nuts 34 are provided along the center of the proximity switch 33. A spring 35 is provided at the top of the sensor mounting hole 29. One end of the spring 35 is fixedly connected to the sensor mounting hole 29, and the other end thereof is fixedly connected to the tension column 31. Two groups of fixed wheel blocks 37 are provided at the top of the tension column 31. A wheel hole 38 is provided on one side of the fixed wheel block 37, and a tension wheel 39 is inserted between the two groups of fixed wheel blocks 37, and the tension wheel 39 is adapted to the wheel hole 38 in shape.

[0038] Specifically, the tension column 31 and the guide disk 26 are installed together by plugging the pin 32, so that the tension column 31 can rotate on the guide disk 26. The spring 35 pulls the tension column 31, so that the lower end of the tension wheel 39 presses the single cable wire. The tension wheel 39 is rotatably connected to the fixed wheel block 37. When the single cable wire breaks, the spring 35 contracts and pulls the tension column 31 as a whole toward the center of the guide disk 26, so that the proximity switch 33 fixed by the fixing nut 34 on the sensor fixing block 28 detects the tension column 31 and transmits the signal to the controller of the device, which stops the motor driving the take-up reel 5 and the drive shaft 21, stopping the entire device, realizing tension sensing and improving the maintenance efficiency after the wire break.

[0039] The working principle of the wire twisting machine device with wire breakage prevention function provided by the utility model is as follows:

[0040] The cable strands on the single-wire column 25 pass through the lower end of the tension wheel 39. The spring 35 pulls the tension column 31, causing the tension wheel 39 to press against the cable strands. Multiple strands of cable strands are then twisted together and guided through the upper and lower guide wheels 4. One end of the twisted strands is then wound onto the take-up reel 5. If one of the strands breaks, the spring 35 contracts, causing the tension column 31 to move toward the sensor fixing block 28. The proximity switch 33 senses the tension column 31, transmitting a signal to the controller, which stops the take-up reel 5 and the drive motor of the drive shaft 21.

[0041] Obviously, the embodiments described above are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
