Description

Technical Field

[0001] This application belongs to the field of barrier net production technology, specifically relating to a barrier net weaving machine. Background Technology

[0002] Tank obstacle nets are military defensive devices specifically designed to delay or impede the advance of enemy tanks and armored vehicles. Tank obstacle nets are typically woven from high-strength steel wires. When a tank track runs over the net, the wires quickly become entangled in the track drive wheels, causing the tracks to derail or break. Due to the complex and extremely resilient structure of the net, even if some wires break, the remaining wires will continue to impede vehicle movement.

[0003] Currently, steel wire is typically wound around a column, and then employees operate machines to fasten and twist the wire. During the process, fluctuations in the tension of the steel wire can cause deviations in the mesh size, requiring frequent manual intervention and increasing the workload of employees. Furthermore, employees need to control the timing of fastening and twisting to ensure consistency, requiring full concentration. Long-term work can lead to fatigue and decreased work efficiency. Additionally, employees need to leave sufficient space between adjacent columns for manual twisting or fastening, and the workshop has a limited number of columns, resulting in low space utilization.

[0024] Please refer to the following: Figures 1 to 14The obstacle net weaving machine provided in this application is described below. The obstacle net weaving machine includes a work frame 1, a wire feeding assembly 3, a twisting assembly 4, a buttoning assembly 5, and a pressing assembly 6. The work frame 1 has a worktable 11 at its bottom, and multiple support columns 2 are installed on the worktable 11; the wire feeding assembly 3 is slidably disposed on the top of the work frame 1 along a first path, and the wire feeding assembly 3 has a wire feeding port located above the worktable 11; the twisting assembly 4 has a twisting column 41 that moves in a circle along a second path, and the twisting column 41 moves along the first path, the second path being perpendicular to the first path; the buttoning assembly 5 has a buttoning head that moves along the first path; the pressing assembly 6 has a pressing end that extends and retracts vertically, and the pressing end moves along the first path; wherein, the wire feeding assembly 3, the twisting assembly 4, the buttoning assembly 5, and the pressing assembly 6 are arranged sequentially along the first path.

[0025] It should be noted that in this application, the metal wire is first introduced into the wire feeding assembly 3, which slides along the first path to stably transport the metal wire from the wire feeding port to the support columns 2 of the workbench 11, and the metal wire is wound around the support columns 2 along the figure-eight rail; then the twisting assembly 4 moves synchronously along the first path, and its twisting column 41 moves in a circle along the second path to perform a spiral twisting operation on the delivered metal wire to form a winding structure; the buckling assembly 5 moves along the first path to the corresponding metal wire and completes the buckling and fixing through the buckling head to prevent the twisted structure from loosening; finally, the pressing assembly 6 moves along the first path, and its pressing end extends and retracts up and down to press and shape the buckled metal wire structure to ensure that the obstacle net mesh structure is stably formed.

[0026] Compared with existing technologies, the obstacle net weaving machine provided in this embodiment achieves full automation of the obstacle net weaving process through the sequential arrangement and synchronous movement of the wire feeding, twisting, buckling, and pressing components 6. Each component moves precisely along a fixed path, and the wire feeding, twisting angle, and buckling position are all precisely controlled by the machine, eliminating the need for frequent manual intervention and significantly reducing the workload of employees. The collaborative operation of each component also improves weaving efficiency, and the mesh size consistency and structural strength are superior to manual weaving, ensuring the obstacle net's entanglement and obstruction effect on tank tracks. Automated operation avoids the fatigue problem caused by long-term, focused manual work, eliminates the need for employees to reserve movement space between the columns, and allows for the increase of the number of support columns 2 on the workbench 11, significantly improving the utilization rate of workshop space.

[0027] In some embodiments, see Figures 1 to 3 The work frame 1 also includes a support frame 12. The support frame 12 is mounted above the worktable 11. The top of the support frame 12 has two sliding columns 13 extending along a first path, and the two sliding columns 13 are located on both sides of the worktable 11. A sliding seat 14 is slidably mounted on the sliding column 13 along the first path. The twisting assembly 4, the buckling assembly 5, and the pressing assembly 6 are respectively connected to the sliding seat 14. The wire feeding assembly 3 is slidably connected to the sliding column 13.

[0028] In this embodiment, the sliding columns 13 on both sides of the support frame 12 provide stable sliding tracks for the wire feeding, twisting, buttoning, and pressing components 6, ensuring the straightness and positional accuracy of each component as it moves along the first path. This avoids problems such as wire feeding deviation, twisting angle misalignment, and inaccurate buttoning position caused by component offset, further improving the consistency of mesh size. The twisting, buttoning, and pressing components 6 are connected to the same sliding seat 14, enabling synchronous movement of the three components, ensuring the continuity of process connections, reducing action delays between components, and improving overall weaving efficiency. The combined design of the support frame 12 and the sliding columns 13 makes the layout of each component more compact, avoiding the problem of loose structure in traditional equipment, and further saving workshop space.

[0029] In practice, the top of the sliding column 13 is provided with a slide rail, and the two sides of the sliding seat 14 are respectively provided with pulleys. The pulleys and the slide rail roll together to drive the sliding seat 14 to move stably along the first path.

[0030] In some embodiments, see Figure 4 and Figure 5 The wire feeding assembly 3 also includes a sliding frame 31, a first connecting rod 32, a second connecting rod 33, and multiple wire guides. The sliding frame 31 is slidably disposed above the worktable 11 along a first path, and the sliding frame 31 has a movable seat 311 that moves along a second path; the first connecting rod 32 is vertically mounted on the movable seat 311; the second connecting rod 33 is mounted on the bottom end of the first connecting rod 32, and the central axis of the second connecting rod 33 is parallel to the second path; multiple wire guides are spaced apart on the second connecting rod 33 along the second path, and a wire guide tube 34 is mounted on the wire guide. The top opening of the wire guide tube 34 forms a wire inlet, and the bottom opening of the wire guide tube 34 forms a wire feeding port. The opening directions of the wire inlet and the wire feeding port are perpendicular to each other.

[0031] The wire feeding assembly 3 provided in this embodiment has a simple structure. The cooperation between the sliding frame 31 and the sliding seat 14 enables bidirectional movement of the wire feeding assembly 3 on the first and second paths. The wire feeding position can be flexibly adjusted according to the weaving specifications of the obstacle net. Multiple wire guide seats are spaced apart along the second path, which can simultaneously feed multiple metal wires, greatly improving weaving efficiency. The design of the wire guide tube 34 with the wire inlet perpendicular to the wire feeding port can guide the metal wire to achieve a 90° turn, avoiding tangling and knotting of the metal wire during the conveying process, and ensuring smooth wire feeding. The wire guide tube 34 plays a limiting role for the metal wire, reducing the shaking of the metal wire during the conveying process, further reducing tension fluctuations, and avoiding mesh deviation caused by wire shaking. The vertical and horizontal combination design of the first and second connecting rods 33 allows the height and horizontal position of the wire guide tube 34 to be precisely adjusted, adapting to the support columns 2 of different heights and the winding requirements of different spacings. There is no need for manual adjustment of the metal wire conveying direction, reducing the workload of employees and improving production stability.

[0032] In some embodiments, see Figure 4 and Figure 5 The wire feeding assembly 3 also includes a wire guide frame 35 and a rotary drive component 38. The wire guide frame 35 is connected to one side of the second connecting rod 33. A rotating rod 36 is provided on the top of the wire guide frame 35. Multiple wire feeding wheels 37 are sleeved on the rotating rod 36. The sides of the wire feeding wheels 37 are provided with wire feeding grooves for the metal wire to pass through. The wire feeding wheels 37 correspond one-to-one with the wire guide tube 34. The multiple wire feeding wheels 37 rotate synchronously with the rotating rod 36. The rotary drive component 38 is installed on the first connecting rod 32. The rotary drive component 38 has a rotary output end. The rotation axis of the rotary output end is parallel to the second path. A synchronous belt 381 is sleeved between the rotary drive component 38 and the rotating rod 36. The synchronous belt 381 is used to drive the rotary output end and the rotating rod 36 to rotate synchronously.

[0033] In practice, the rotary drive component 38 can be a servo motor or a stepper rotary motor, as long as it can drive the synchronous belt 381 to rotate.

[0034] The wire feeding groove on the wire feeding wheel 37 provided in this embodiment can precisely limit the position of the metal wire, preventing it from falling off the wheel during conveying and ensuring the straightness of the wire conveying. Multiple wire feeding wheels 37 rotate synchronously with the rotating rod 36, and are driven by the rotating drive component 38 through the synchronous belt 381 to ensure that the conveying speed of each metal wire is consistent. Stable tension can prevent the metal wire from being stretched, deformed or broken due to uneven force, while ensuring that the mesh size deviation is controlled within a very small range, improving the product qualification rate of the barrier net. The wire feeding wheel 37 corresponds one-to-one with the wire guide tube 34, making the conveying path of each metal wire independent and precise, avoiding mutual interference between multiple wires, and further reducing the risk of entanglement. The synchronous belt 381 drive has the characteristics of smooth transmission, low noise, and convenient maintenance, reducing the probability of failure during equipment operation and reducing the workload of employees. The rotation speed of the rotating drive component 38 is adjustable, which can adapt to the conveying needs of metal wires of different diameters, improving the adaptability of the equipment, eliminating the need for manual control of the wire feeding speed, reducing labor intensity, and improving production efficiency.

[0035] In some embodiments, see Figure 3 , Figures 6 to 8 The bottom of the sliding seat 14 has a lifting seat 15 that can move up and down. The twisting assembly 4 includes a twisting housing 42, a twisting drive 43, and a limiting plate 44. The twisting housing 42 is installed at the bottom of the lifting seat 15, and a twisting column 41 is installed at the bottom of the twisting housing 42. The twisting drive 43 is installed on the upper surface of the lifting seat 15. The twisting drive 43 has a drive end, which is connected to the twisting column 41 in a transmission manner. The limiting plate 44 is installed on one side of the twisting housing 42 that is perpendicular to the second path. The limiting plate 44 has a limiting groove with an opening facing downward.

[0036] In specific implementation, the bottom of the lifting seat 15 is provided with a lifting plate, which is set horizontally. The twisting housing 42 is installed at the bottom of the lifting plate, and the twisting drive component 43 is installed on the upper surface of the lifting plate. Multiple twisting drive components 43 can be installed on the lifting plate to enable multiple twisting housings 42 to work at the same time and improve twisting efficiency.

[0037] In this embodiment, the twisting assembly 4 can move up and down. The lifting seat 15 can drive the twisting housing 42 and the twisting column 41 to move up and down. The working height of the twisting column 41 can be flexibly adjusted according to the diameter of the metal wire, the height of the support column 2, and the twisting density, improving the versatility of the equipment. The twisting drive component 43 provides stable power to the twisting column 41, ensuring uniform twisting force and speed, avoiding the loose twisting structure or metal wire breakage caused by uneven force during manual twisting, ensuring consistent tightness of each twist, and improving the toughness of the obstacle net. The limiting groove of the limiting plate 44 can position the metal wire, preventing the metal wire from deviating during the twisting process, ensuring accurate twisting position, and avoiding mesh deformation caused by position deviation; the limiting groove can also guide the metal wire smoothly into the twisting area, reducing the probability of interruption in the twisting process. Automated twisting operation does not require employees to concentrate on controlling the twisting direction, reducing labor intensity, avoiding the decline in work efficiency caused by fatigue, and the stable transmission of the twisting drive component 43 reduces the error rate of the twisting process and improves the overall production quality.

[0038] In some embodiments, see Figure 8 The twisting column 41 includes a rotating body 411, a first fixing rod 412, and a second fixing rod 413. The rotating body 411 is rotatably mounted on the bottom of the twisting housing 42, and the rotation axis of the rotating body 411 is parallel to the first path. The rotating body 411 is connected to the drive end for transmission. An avoidance groove is provided on the outer peripheral surface of the rotating body 411 to allow the metal wire to enter the avoidance groove. The first end of the first fixing rod 412 is connected to one end of the rotating body 411 and rotates around the rotation axis of the rotating body 411. The axial direction of the first fixing rod 412 is parallel to the first path. The second fixing rod 413 is connected to the second end of the first fixing rod 412, and the axial direction of the second fixing rod 413 is perpendicular to the axial direction of the first fixing rod 412.

[0039] In this embodiment, the clearance groove of the rotating body 411 can accurately accommodate the metal wire, preventing the wire from slipping off the twisting column 41 during the twisting process, reducing rework caused by wire misalignment, and improving process continuity. The first fixing rod 412 rotates synchronously with the rotating body 411 around a specific axis. Combined with the vertical design of the second fixing rod 413, the metal wire can form a regular spiral winding structure, ensuring that the spiral angle and winding density of each twist are consistent, and avoiding a loose mesh structure caused by chaotic twisting direction.

[0040] In practice, the twisting drive 43 is connected to the twisting column 41. Multiple transmission wheels are installed inside the twisting housing 42. The multiple transmission wheels mesh so that the output end of the twisting drive 43 can drive the twisting column 41 to move. The specific working principle of the twisting column 41 is common knowledge in this field and is the same as the principle of manual twisting equipment, so it will not be described in detail here.

[0041] In some embodiments, see Figure 11 and Figure 12 The fastening assembly 5 includes a nailing machine 51 and a guide plate 52. The nailing machine 51 is installed on one side of the lifting base 15, and a fastening head is formed at the bottom of the nailing machine 51; the guide plate 52 is located on the side of the bottom of the nailing machine 51 perpendicular to the first path, and a guide groove is opened at the bottom of the guide plate 52, the vertical width of the guide groove gradually decreasing from top to bottom.

[0042] It should be noted that the nailing machine 51 includes a nailing body, a receiving tube, a nailing drive, and a nailing plate. The nailing body has a nailing channel running vertically through the nailing channel. The nailing drive is installed at the top of the nailing channel and has a forming end that moves along the nailing channel. The receiving tube is located on one side of the nailing body, and its bottom end is connected to the bottom end of the nailing channel. The receiving tube contains multiple nails specifically for tank obstacle nets. The nailing plate is installed on the side of the nailing body and has multiple through holes of different sizes. The required through holes are selected to connect the nailing channel and the bottom end of the receiving tube. When the nailing body descends, the multiple metal wires to be fastened are gathered together along the guide groove. A nail is released from the receiving tube, passes through the through hole, and enters the nailing channel. The forming end moves downward, pushing the nail downward. Under the action of the nailing channel, the forming end becomes a ring-shaped nail, which fastens the multiple metal wires together.

[0043] The snap-fit ​​assembly 5 in this embodiment has a simple structure. The lifting seat 15 drives the snap-fit ​​machine 51 to rise and fall synchronously, and the snap-fit ​​head position can be flexibly adjusted according to the height of the twisted wire and the snap-fit ​​specifications. The snap-fit ​​machine 51 provides automated snap-fit ​​power, with stable snap-fit ​​force and frequency, avoiding the loosening of the snap-fit ​​or damage to the wire caused by uneven force during manual snap-fitting, ensuring that each snap-fit ​​can firmly fix the twisted structure, preventing mesh deformation, and improving the stability of the obstacle net structure. The guide groove of the guide plate 52 has a "wide at the top and narrow at the bottom" design, which can guide the wire to accurately enter the snap-fit ​​area, avoiding the snap-fit ​​position deviation caused by wire offset, and reducing the probability of snap-fit ​​failure. At the same time, the guide groove can also pre-position the wire before snap-fitting, shorten the snap-fitting preparation time, and improve process efficiency. Automated snap-fitting does not require employees to concentrate on controlling the snap-fitting position, reducing visual fatigue, reducing labor intensity, and the snap-fitting speed is much faster than manual snap-fitting, greatly improving overall production efficiency.

[0044] In practice, the finished tank obstacle net is a circular structure. The side of the finished product on the first path is twisted, and the side of the finished product on the second path is buckled, so that the twisting and buckling on the tank obstacle net are alternately set.

[0045] In some embodiments, see Figure 13 and Figure 14 The pressing assembly 6 also includes a pressing frame 61, a pressing drive 62, and a pressing plate 63. The pressing frame 61 has a mounting plate at its bottom; the pressing drive 62 is mounted on the mounting plate, and the bottom of the pressing drive 62 has a pressing end that extends vertically, with the pressing end protruding from the mounting plate; the pressing plate 63 is connected to the pressing end, and the bottom surface of the pressing plate 63 forms the pressing end.

[0046] The extrusion drive 62 in this embodiment provides stable up-and-down extension and retraction power, ensuring uniform and consistent pressing pressure. This results in more stable mesh sizes after pressing, tighter wire bonding, and enhanced impact resistance of the barrier net. The extrusion plate 63 increases the contact area with the wires, allowing for simultaneous pressing and shaping of multiple wires or mesh nodes, improving pressing efficiency. Furthermore, the flat bottom surface of the extrusion plate 63 prevents wire breakage due to excessive localized pressing, ensuring the integrity of the net. The pressing assembly 6 moves synchronously along the first path with the sliding seat 14, seamlessly connecting with the wire feeding, twisting, and knotting processes, reducing process intervals and improving overall weaving efficiency.

[0047] In practice, two extrusion components are set up with a gap between them. The extrusion plates 63 of the two extrusion components rise and fall synchronously, which can press the metal wires on both sides of the support column 2 on the first path. The support column 2 enters the gap, ensuring that the extrusion plate 63 can descend normally.

[0048] In some embodiments, see Figure 2 The workbench 11 is provided with multiple support plates arranged at intervals along the first path, and the length direction of each support plate is parallel to the second path; the multiple support columns 2 are divided into first winding columns 201 and second winding columns 202. The multiple first winding columns 201 and multiple second winding columns 202 are alternately arranged on the multiple support plates along the first path. The distance between two adjacent first winding columns 201 on the same support plate is greater than the distance between two adjacent second winding columns 202 on the same support plate.

[0049] In this embodiment, the support plate provides stable support for the support column 2, preventing the support column 2 from tilting due to the tension of the metal wire winding, ensuring accurate wire positioning during the winding process, and reducing mesh deviation. The first winding column 201 and the second winding column 202 are alternately arranged with different spacing. The metal wire passes around the first winding column 201 and the second winding column 202 along a specific trajectory, which can flexibly weave mesh structures of different densities. The combination of the two meshes can enhance the winding effect of the obstacle net on the tracks of different types of tanks. This design allows the support columns 2 to be densely arranged on the workbench 11 without reserving gaps for manual movement, greatly improving the utilization rate of workshop space; the alternating arrangement of the winding columns makes the metal wire winding path more regular, avoiding wire crossing and confusion, reducing jamming during the weaving process, improving production smoothness, and eliminating the need for manual adjustment of the winding column spacing, reducing operational complexity and improving production efficiency.

[0050] In some embodiments, see Figure 9 and Figure 10 The support column 2 includes a support body 21, a first positioning rod 22, a support arm 25, a second positioning rod 23, and an elastic element 24. The support body 21 is erected on the workbench 11. A sliding groove is formed on the side of the support body 21, and a receiving cavity communicating with the sliding groove is formed inside the support body 21. The first positioning rod 22 is installed in the receiving cavity, and the axis of the first positioning rod 22 is parallel to the second path. The first end of the support arm 25 is rotatably connected to the first positioning rod 22, and the second end extends out of the sliding groove. The second positioning rod 23 is installed in the receiving cavity and is spaced vertically from the first positioning rod 22. The axis of the second positioning rod 23 is parallel to the second path. The two ends of the elastic element 24 are respectively connected to the middle of the second positioning rod 23 and the support arm 25. The elastic element 24 is configured with a preload to push the support arm 25 to keep it horizontal.

[0051] In this embodiment, the support arm 25 remains horizontal under the pre-tension of the elastic element 24, providing stable support for the metal wire. When the tension of the metal wire changes, the support arm 25 can rotate flexibly around the first positioning rod 22. The downward pressure of the metal wire causes the support arm 25 to swing downward, allowing the snapped metal wire to fall onto the outer periphery of the support body 21 without changing its shape. The support body 21 then shapes the mesh of the snapped metal wire. The support arm 25 will then reset, supporting the two newly fallen metal wires for snapping. The metal wires are directly stacked on the shaping post, avoiding mesh deformation that may occur during transport and ensuring the stability of the obstacle net structure. The first positioning rod 22 enables the stable rotation of the support arm 25, while the second positioning rod 23 provides an installation reference for the elastic element 24. The pre-tension of the elastic element 24 automatically drives the support arm 25 to swing upward and reset to the snapping state after it swings down. After completing one snapping operation, the support arm 25 can automatically return to its working position, waiting for the next snapping operation, thus improving the continuity of the operation.

[0052] In practice, the elastic element 24 can be a helical spring or a rubber strip, as long as it can drive the support arm 25 to return to its original position.

[0053] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
