Description

Technical Field

[0001] This invention relates to the field of chain link fence edge locking technology, specifically to a chain link fence edge locking adjustment device. Background Technology

[0002] Chain link fencing is a flexible mesh product made of metal wires through mechanical bending and weaving. Its structural feature is that each metal wire interlocks securely at its intersections, forming a uniform diamond-shaped mesh. The overall mesh surface has advantages such as good elasticity, resistance to deformation, and strong impact resistance. It is used in fields such as stadium fencing, slope protection, livestock fencing, landscaping, and industrial isolation, combining protective functions with aesthetic appeal. The surface is often treated with galvanizing or PVC coating to enhance corrosion resistance and adaptability to different environmental requirements.

[0003] The chain link fence edge-locking adjustment device is a specialized mechanism used in chain link fence production equipment. It is primarily used for the automatic and precise tightening and fixing of the edges of the woven chain link fence. Its core function lies in controlling the force and position of the edge-locking die or pressure roller through an adjustable mechanical structure, thereby ensuring that the steel wires at the edge are tightly and evenly wrapped around the main mesh, forming a strong and neat edge seal. This device effectively solves the quality problems of low efficiency and inconsistent tightness associated with manual edge-locking, improving the degree of automation and product consistency in production. It is a key equipment component ensuring the edge strength, aesthetics, and overall structural stability of the chain link fence.

[0004] During use, the adjustment device lacks compatibility for chain link fences with different wire diameters, mesh sizes, and materials. Changing products requires replacing a large number of parts or making complex adjustments, which delays production time. In existing technology, the locking head, guide nozzle, and clamping block that directly contact the wire are designed as quick-change modules with standard interfaces. A series of standard modules are prefabricated for different wire diameters and materials. However, during use, the wires intertwine and are uneven. When locking the edges, the folding and shrinking machine cannot efficiently fold the wire ends, resulting in messy and interlocked wire ends, a high risk of loosening, and uneven strength. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a chain link fence edge-locking adjustment device, which solves the problems of interlaced and uneven mesh wires, the inability of the folding and shrinking machine to efficiently fold the wire ends during edge-locking, resulting in messy and interlocked wire ends, high risk of loosening, and uneven strength.

[0016] This invention provides a chain link fence edge adjustment device. It has the following advantages: 1. This invention starts the first motor on the support plate, which drives the turntable to rotate. The turntable drives the connecting rod and the U-shaped block to move. When the U-shaped block moves, the round shaft inside it drives the gear fixed in the middle to move. One side of the gear meshes with the rack, and the other side meshes with the push rod to drive the push rod and the cylinder and fixed rod installed on it to move. Since the cylinder has parallel grooves and curved grooves, the sliding ball on the vertical plate will first pass through the parallel groove and then enter the curved groove, thereby causing the cylinder and fixed rod to rotate.

[0017] 2. When the circular shaft of this invention rotates, it drives the discs on both sides to rotate. The rotation of the discs is converted into thrust through the cooperation of the moving rod and the L-shaped rod, which pushes the L-shaped rod to move. The fixed plate on the bearing plate is equipped with a pushing block inside. The L-shaped rod contacts and pushes the block to move, which drives the moving short rods on both sides of the block to move. The moving long rod rotates around the rotating column as the center point. One end of the long rod is connected to the moving short rod, so it is driven to move. The second pressure plate fixed at the other end is close to the first pressure plate. The two pressure plates are connected by a spring, which plays a role in resetting.

[0018] 3. The second motor of this invention outputs kinetic energy to drive the rotating shaft to rotate. The rotating shaft drives the triangular connecting rod to move. The two ends of the triangular connecting rod respectively pull the first rotating long rod to move. The movement of the first and second rotating long rods drives the third rotating long rod to rotate. The third rotating long rod pushes the push block with the help of the fixed short rod. The push block drives the push plate to rise or fall. The other end of the third rotating long rod drives the fourth rotating long rod to rotate around the middle of the fixed triangular block as the fulcrum. This realizes that the push plate contacts the net and clamps the net to move forward, avoiding uneven tension of the net that affects subsequent processing. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

Pre-processing mechanisms 2 are provided on both sides of the top of the machine body 1. The pre-processing mechanisms 2 are used to pre-flatten the edges of the net body 5. A pressing mechanism 3 is provided on the outer side of the pre-processing mechanisms 2, used to press down and fix the edges of the net body 5. A pushing mechanism 4 is provided on the outer side of the support frame 18, used to push the net body 5. The pre-processing mechanism 2 includes two bearing plates 21, which are respectively fixedly connected to both sides of the machine body 1. A first motor 22 is fixedly connected to the top of the bearing plates 21. A turntable 23 is fixedly connected to the output end of the first motor 22. A connecting rod 24 is rotatably connected to the outer side of the turntable 23. A U-shaped block 25 is rotatably connected to the other end of the connecting rod 24. A round shaft 212 is rotatably connected to the middle of the U-shaped block 25, and a gear is fixedly connected to the middle of the round shaft 212. 26. A rack 27 is fixedly connected to the top of the bearing plate 21, and a gear 26 meshes with the rack 27. A rotating plate 28 is fixedly connected to the top of the bearing plate 21, and a push rod 29 is slidably connected to the middle of the rotating plate 28. The gear 26 meshes with the push rod 29. A cylinder 210 is rotatably connected to the other end of the push rod 29 away from the rotating plate 28. Parallel grooves 215 and curved grooves 216 are sequentially formed on the outer side of the cylinder 210 from left to right. The parallel grooves 215 and curved grooves 216 are connected to each other. The grooves 216 are connected, and the other end of the cylinder 210 is fixedly connected to a fixing rod 211. The top of the bearing plate 21 is fixedly connected to a vertical plate 213, and the top of the vertical plate 213 is fixedly connected to a sliding ball 214. The sliding ball 214 is slidably connected inside the parallel groove 215 and the curved groove 216. The front side of the U-shaped block 25 is fixedly connected to a limiting rod 13. The middle part of the bearing plate 21 is provided with a moving groove 14, and the limiting rod 13 is slidably connected inside the moving groove 14. Specifically, the first motor 22 on the support plate 21 is started. The kinetic energy of the first motor 22 can drive the turntable 23 to rotate. The rotation of the turntable 23 causes the connecting rod 24 and the U-shaped block 25 to move. When the U-shaped block 25 moves, the internal circular shaft 212 drives the gear 26 fixed in the middle to move. One side of the gear 26 meshes with the rack 27, and the other side meshes with the push rod 29 to drive the push rod 29 to move. This in turn drives the cylinder 210 and the fixed rod 211 installed on the push rod 29 to move. Since the cylinder 210 has a parallel groove 215 and a curved groove 216, the sliding ball 214 on the vertical plate 213 can pass through the parallel groove 215 first and then enter the curved groove 216, which will cause the cylinder 210 and the fixed rod 211 to rotate.

[0025] Reference Figure 2 , Figure 6 and Figure 7The pressing mechanism 3 includes two discs 31, which are fixedly connected to the two ends of a circular shaft 212.

A first spring 39 is fixedly connected to the bottom of the second pressure plate 312. A first pressure plate 32 is fixedly connected to the other end of the first spring 39. Two sliding grooves 16 are opened on the top of the bearing plate 21. L-shaped rods 34 are slidably connected to the inside of the sliding grooves 16. Sliding blocks 15 are fixedly connected to the bottom of the two L-shaped rods 34. A limiting groove 17 is opened inside the bearing plate 21. Sliding blocks 15 are slidably connected to the inside of the limiting groove 17. Specifically, when the circular shaft 212 rotates, it will drive the discs 31 on both sides to rotate accordingly. The rotation of the discs 31 is converted into a driving force through the coordinated action of the moving rod 33 and the L-shaped rod 34, which in turn drives the L-shaped rod 34 to move. A fixed plate 35 is fixed on the bearing plate 21, and a pushing block 36 is installed inside the fixed plate 35. When the L-shaped rod 34 contacts the pushing block 36, it will push the pushing block 36 to move, thereby driving the moving short rods 37 on both sides of the pushing block 36 to move. The moving long rod 310 rotates around the rotating column 311. Since the other end of the moving long rod 310 is connected to the moving short rod 37, it can drive one side of the moving long rod 310 to move. The second pressure plate 312 fixed at the other end of the moving long rod 310 will approach the first pressure plate 32. The two are connected by the first spring 39, which plays a role in resetting.

The end of the fourth rotating long rod 49 away from the third rotating long rod 48 is rotatably connected to the middle of the fixed triangular blocks 410. Specifically, the second motor 43 outputs kinetic energy to drive the rotating shaft 44 to rotate. The rotating shaft 44 drives the triangular connecting rod 45 to move, and the two ends of the triangular connecting rod 45 respectively pull the first rotating long rod 46 to move. The movement of the first rotating long rod 46 and the second rotating long rod 47 causes the third rotating long rod 48 to rotate. The third rotating long rod 48 pushes the push block 41 through the fixed short rod 411. The push block 41 drives the push plate 412 to rise or fall. The other end of the third rotating long rod 48 drives the fourth rotating long rod 49 to rotate around the middle of the fixed triangular block 410 as the fulcrum. The push plate 412 contacts the net body 5 and clamps the net body 5 to move forward, thereby avoiding the net body 5 from being affected by uneven tension in subsequent processing.

[0027] Reference Figure 1 , Figure 2 and Figure 10 Mounting plates 6 are fixedly connected to both sides of the support frame 18. A horizontal plate 7 is installed on the top of the support frame 18. A screw 8 is slidably connected to the middle of the mounting plate 6. The mounting plate 6 can be fixed to the support frame 18 by the screw 8. The screw 8 is threadedly connected to the horizontal plate 7. A second spring 9 is fixedly connected to the bottom of the horizontal plate 7 around the perimeter, which plays the role of compression and rebound. An upper pressure plate 10 is fixedly connected to the end of the second spring 9 away from the horizontal plate 7. A winding frame 11 is provided on the front side of the machine body 1. Anti-slip pads 12 are fixedly connected to the bottom of the machine body 1 and the winding frame 11 for support and anti-slip effect. Specifically, both sides of the support frame 18 are fixedly connected to the mounting plate 6. A horizontal plate 7 is installed on the top of the support frame 18. The middle part of the mounting plate 6 is slidably connected to the screw 8. The mounting plate 6 can be fixed to the support frame 18 by the screw 8. The screw 8 and the horizontal plate 7 are threadedly connected. The bottom of the horizontal plate 7 is fixedly connected to the second spring 9 around its perimeter. The second spring 9 plays a compression and rebound role. The end of the second spring 9 away from the horizontal plate 7 is fixedly connected to the upper pressure plate 10. A winding frame 11 is provided on the front side of the machine body 1. The bottom of the machine body 1 and the winding frame 11 are fixedly connected to the anti-slip pad 12. The anti-slip pad 12 is used for support and plays an anti-slip role.

[0028] Working principle: The first motor 22 on the support plate 21 is started, and its kinetic energy can drive the turntable 23 to rotate. The rotation of the turntable 23 causes the connecting rod 24 and the U-shaped block 25 to move. When the U-shaped block 25 moves, the internal circular shaft 212 drives the gear 26 fixed in the middle to move. One side of the gear 26 meshes with the rack 27, and the other side of the gear 26 meshes with the push rod 29 to drive the push rod 29 to move. This in turn drives the cylinder 210 and the fixed rod 211 installed on the push rod 29 to move. Since the cylinder 210 has a parallel groove 215 and a curved groove 216, the sliding ball 214 on the vertical plate 213 can pass through the parallel groove 215 and then the curved groove 216, which will cause the cylinder 210 and the fixed rod 211 to rotate.

[0029] When the circular shaft 212 rotates, it drives the discs 31 on both sides to rotate. The rotation of the discs 31 is converted into a driving force through the cooperation of the moving rod 33 and the L-shaped rod 34, which pushes the L-shaped rod 34 to move. A fixed plate 35 is fixed on the bearing plate 21, and a pushing block 36 is installed inside it. The L-shaped rod 34 contacts the pushing block 36 and pushes the pushing block 36 to move, which drives the moving short rods 37 on both sides of the pushing block 36 to move. The moving long rod 310 rotates around the rotating column 311. The other end of the moving long rod 310 is connected to the moving short rod 37, which can drive one side of the moving long rod 310 to move. The second pressure plate 312 fixed at the other end of the moving long rod 310 is close to the first pressure plate 32. The two are connected by the first spring 39, which plays a role in resetting. The second motor 43 outputs kinetic energy to drive the rotating shaft 44 to rotate. The rotating shaft 44 drives the triangular connecting rod 45 to move. The two ends of the triangular connecting rod 45 respectively pull the first rotating long rod 46 to move. The movement of the first rotating long rod 46 and the second rotating long rod 47 drives the third rotating long rod 48 to rotate. The third rotating long rod 48 pushes the push plate 412 with the help of the fixed short rod 411. The push block 41 drives the push plate 412 to rise or fall. At the same time, the other end of the third rotating long rod 48 drives the fourth rotating long rod 49 to rotate around the middle of the fixed triangular block 410 as the fulcrum. Finally, the push plate 412 contacts the net body 5 and clamps the net body 5 to move forward, so as to avoid uneven tension of the net body 5 affecting subsequent processing.
