[0001] The present invention relates to the technical field of blade barbed wire production, and particularly to an automatic buckle device for blade barbed wire. Background Art

[0002] Blade barbed wire is a new type of protective net, which is usually composed of galvanized steel plates or stainless steel plates stamped into blade shapes and galvanized iron wires or steel wires. These blade-shaped metal strips are wound around the iron wires or steel wires and fixed together by buckles to form a continuous protective belt.

[0003] Currently, in the production process of blade barbed wire, the production of blades and the winding with iron wires or steel wires have been automated, but the installation of buckles still requires manual operation. Usually, workers use mechanical pliers or pneumatic pliers to complete it. This method not only consumes a large amount of labor, but also poses a potential risk to the safety of operating workers due to the sharp characteristics of the blade barbed wire itself.

[0045] Please see Figure 1-8 This invention provides a technical solution: an automatic locking device for barbed wire, wherein the overall locking device is slidably mounted on a work platform, comprising:

[0046] Specifically, such as Figure 1 , Figure 4 and Figure 5The shown frame assembly 1 includes side brackets 11, a bottom bracket 12, a third slide rail 13, a third slide block 14, a mounting bracket 15, a third sliding frame 16, and a sixth cylinder 6. Side brackets 11 are fixedly connected to both sides of the bottom bracket 12. Multiple groups of third slide rails 13 are fixedly connected to the bottom bracket 12. The third slide block 14 is slidably mounted on the third slide rail 13. The third slide block 14 is fixedly connected to the third sliding frame 16. The sixth cylinder 6 is fixedly mounted on the bottom bracket 12. The piston rod end of the sixth cylinder 6 is fixedly connected to the third sliding frame 16. The mounting bracket 15 is fixedly connected to the third sliding frame 16. It further includes a fixed block 9 and a square rod 40. Fixed blocks 9 are fixedly provided between the first jaw frame 17 and the third sliding frame 16, and between the first jaw frame 17 and the second jaw frame 18. The fixed block 9 between the two groups of jaw frames has a placement groove 8 for accommodating the buckle. The placement groove 8 is arranged perpendicular to the movement direction of the ejector rod 42. A guide groove 10 corresponding to the placement groove 8 is provided on the second jaw frame 18. The square rod 40 is fixedly connected to the second jaw frame 18. The square rod 40 is guidingly installed along the movement direction of the third sliding frame 16. The sixth cylinder 6 drives other components connected to the third sliding frame 16 to move synchronously. These components include the ejector rod assembly 4, the buckle-pushing component 5, the jaw frames, the clamping block 19, the fixed block 9, the square rod 40, etc.

[0047] Specifically, as Figure 2 The shown first flap component 2 is arranged at the front bottom side of the frame assembly 1. The first flap component 2 includes a first flap 24 with a "mouth"-shaped movement trajectory. It further includes a first sliding frame 21, a first slide rail 22, a first slide block 23, a first cylinder 25, and a second cylinder 26. First slide rails 22 are fixedly arranged on both sides of the first sliding frame 21. The first slide block 23 is slidably mounted on the first slide rail 22. The first slide block 23 is fixedly connected to the bottom bracket 12. The first cylinder 25 is fixedly mounted on the first sliding frame 21. The piston rod end of the first cylinder 25 is fixedly connected to the first flap 24. The second cylinder 26 is fixedly mounted on the bottom bracket 12. The piston rod end of the second cylinder 26 is fixedly connected to the first sliding frame 21. The second cylinder 26 drives the first sliding frame 21, the first cylinder 25, the first flap 24, and the first slide block 23 to move back and forth along the direction of the first slide rail 22. The first cylinder 25 drives the first flap 24 to move left and right. That is, the purpose of setting the first flap component 2 is: to enable the first flap 24 to perform telescopic movement in two directions along the first cylinder 25 and the second cylinder 26, to make the first flap 24 achieve a "mouth"-shaped running trajectory. The first flap 24 is used to拨动 the barbed wire blade to move along the telescopic direction of the first cylinder 25, which can be used to拨动 the barbed wire blade to move. On the one hand, it拨动 the barbed wire blade to be clamped to the buckle clamping operation position, and on the other hand, it拨出 the clamped barbed wire blade.

[0048] Specifically, as Figure 3The second paddle assembly 3 shown is located at the front end of the frame assembly 1 and above the first paddle assembly 2. The second paddle assembly 3 includes a second paddle 33 with a linear motion trajectory, a third cylinder 31, a fixed frame 32, a second slide block 34, and a second slide rail 35. The third cylinder 31 and the fixed frame 32 are fixedly connected to the base support 12. The piston rod end of the third cylinder 31 is fixedly connected to the second paddle 33. The second slide rail 35 is fixedly connected to both sides of the top of the second paddle 33. The second slide block 34 is slidably mounted on the second slide rail 35 and fixedly connected to the fixed frame 32. The third cylinder 31 drives the second slide rail 35 and the second paddle 33 to move back and forth along the direction of the second slide block 34 on the fixed frame 32. The purpose of the second paddle assembly 3 is to enable the second paddle 33 to extend and retract along the direction of the third cylinder 31, thus positioning the barbed wire.

[0049] Specifically, such as Figure 5-7 As shown, the assembly includes a first jaw frame 17, a second jaw frame 18, two sets of clamping blocks 19, a bearing 20, and a spring 30. The two sets of jaw frames are slidably arranged at the front end of the frame assembly 1. The two sets of clamping blocks 19 are rotatably installed between the jaws of the two sets of jaw frames by screws. The end of the clamping block 19 away from the jaw end a is rotatably connected to the bearing 20 through a rotating shaft. The two ends of the spring 30 are respectively fixedly connected to the middle of the two clamping blocks 19. The front protrusion d of the protrusion 43 is located between the two sets of bearings 20. The spring 30 ensures that the bearing 20 is always in contact with the front protrusion d of the protrusion 43. When the protrusion 43 moves forward, it squeezes the two sets of bearings 20 to open the rear ends of the two sets of clamping blocks 19 outward. Due to the lever principle, the front ends of the two sets of clamping blocks 19 move closer to each other and close the opening end b. After clamping the buckle, the push rod 42 squeezes the buckle to clamp it onto the barbed wire. Then, when the protrusion 43 moves backward and disengages from between the two sets of bearings 20, under the elastic action of the spring 30, the rear ends of the two sets of clamping blocks 19 move closer to each other, and the opening end b of the front end of the two sets of clamping blocks 19 opens again, clamping the buckle again.

[0050] Among them, such as Figure 1 As shown, the first lever 24 and the second lever 33 are respectively provided with a number of slots c for locking the barbed wire. The jaw ends a of the two sets of jaw frames and the open ends b of the two sets of clamping blocks 19 correspond to the slots c. Each two adjacent turns of barbed wire are located in the jaw ends a, the open ends b of the two sets of clamping blocks 19 and the slots c. The operating buckle is engaged with the two adjacent turns of barbed wire placed in the slots c of the second lever 33.

[0051] Specifically, such as Figure 5 and Figure 7The push rod assembly 4 shown is slidably mounted on the frame assembly 1. The push rod assembly 4 includes a fourth cylinder 41 with a linear motion trajectory, a push rod 42, a protrusion 43, and a seventh cylinder 44. The fourth cylinder 41 is fixedly mounted on the mounting bracket 15, and the seventh cylinder 44 is fixedly mounted on the third sliding frame 16. The piston rod end of the fourth cylinder 41 is fixedly connected to the rear end of the push rod 42, and the piston rod end of the seventh cylinder 44 is fixedly connected to the protrusion 43. The front end of the push rod 42 has a V-shaped opening e. The protrusion 43 is slidably connected to the push rod 42. The protrusion is used to drive two sets of clamping blocks 19 to rotate around the screw to position the buckle. The push rod 42 is used to compress and deform the buckle to clamp the barbed wire. The seventh cylinder 44 drives the protrusion 43 to move forward, thereby driving the front ends of the two sets of clamping blocks 19 to rotate towards each other to clamp the buckle. The fourth cylinder 41 drives the push rod 42 to move forward, and the V-shaped opening e at the front end of the push rod 42 compresses and deforms the buckle, which then engages with two adjacent turns of the barbed wire.

[0052] It should be noted that during the operation of the push rod assembly 4, the seventh cylinder 44 first drives the protrusion 43 to extend and cause the two sets of clamping blocks 19 to clamp the buckle at the open end b. Then, the fourth cylinder 41 drives the V-shaped opening e at the front end of the push rod 42 to squeeze the buckle and engage it with the barbed wire. After that, the fourth cylinder 41 first drives the push rod 42 to retract and disengage from the buckle, and then the seventh cylinder 44 drives the protrusion 43 to retract and disengage from the two sets of clamping blocks 19, thus releasing the buckle.

[0053] Specifically, such as Figure 6 The latch assembly 5 shown is mounted on the first jaw bracket 17 and is used to feed the latch into the front end of the push rod 42. The latch assembly 5 includes a fifth cylinder 51, a connecting bracket 52, a fourth slide rail 53, a fourth slide block 54, a lever 55, and a tension spring 56. The fifth cylinder 51 and the fourth slide rail 53 are fixedly mounted on the second jaw bracket 18, and the fourth slide block 54 is slidably mounted on the fourth slide rail 53. The piston rod end of the fifth cylinder 51 is fixedly connected to the fourth slide block 54 through the connecting bracket 52. The lever 55 is rotatably mounted on the fourth slide block 54. One end of the lever 55 passes through the guide groove 10 and extends into the placement groove 8. One end of the tension spring 56 is engaged with the fourth slide block 54, and the other end of the tension spring 56 is engaged with the other end of the lever 55. The fifth cylinder 51 drives the connecting frame 52, the fourth slide block 54, the lever 55, and the tension spring 56 to move along the fourth slide rail 53. The lower end of the lever 55 moves within the placement groove 8 and the guide groove 10, causing the lower end of the lever 55 to move to the front end of the buckle assembly arranged in the placement groove 8. When the piston rod end of the fifth cylinder 51 retracts, the lever 55 sends out a set of buckles to the front end of the push rod 42. That is, the purpose of setting the buckle assembly 5 is to move the buckles towards the moving track of the push rod 42 through the extension and retraction action of the fifth cylinder 51.

[0054] Specifically, such as Figure 1As shown, it also includes a valve island 7, which is fixedly installed at the rear end of the base bracket 12. The valve island 7 is connected to the cylinder in the snap-fit ​​device through an air pipe and is used to control the movement of the cylinder piston rod.

[0065] Repeat steps S1-S9 to achieve continuous automatic locking of barbed wire and improve work efficiency.

[0066] When the first cylinder 25 and the second cylinder 26 retract, the barbed wire comes out of the slot c of the first paddle 24. When the second cylinder 26 extends, the first paddle 24 locks the barbed wire. When the first cylinder 25 retracts, the first paddle 24 pulls out the barbed wire that has been locked.

[0067] When the third cylinder 31 extends, the second paddle 33 engages the barbed wire to complete the latching operation. When the third cylinder 31 retracts, the barbed wire disengages from the latch of the second paddle 33 without interfering with the operation of the first cylinder 25 to pull out the barbed wire through the first paddle 24.

[0068] When the seventh cylinder 44 extends, it pushes the opening end b of the clamping block 19 to close the clamping buckle through the protrusion 43. When the fourth cylinder 41 extends, it drives the push rod 42 to move forward. The V-shaped opening e at the front end of the push rod 42 squeezes and deforms the buckle and engages with the two adjacent turns of the barbed wire.

[0069] When the sixth cylinder 6 extends, it sends the jaw end a and the open ends b of the two sets of clamping blocks 19 into the outer side of the two adjacent rings of barbed wire located at the slot c of the second paddle 33, so as to complete the snap-fit ​​operation. When the sixth cylinder 6 retracts, the barbed wire is disengaged from the jaw end a and the open ends b of the two sets of clamping blocks 19, without interfering with the operation of the first cylinder 25 to pull out the barbed wire through the first paddle 24.

[0070] When the fifth cylinder 51 extends, the rear end of the buckle group arranged in the slot 8 is moved by the paddle plate 55.
