When a single steel bar bundling machine 15 is not working, the wire reel brake device 30 brakes the wire reel mechanism 4. When a single steel bar bundling machine 15 is working, the wire reel brake rod 31 will be driven forward by the wire binding wire on the wire reel 29. At this time, the wire reel brake rod 31 will drive the wire reel brake device 30 to release the wire reel mechanism 4, so that the wire reel 29 rotates. After the bundling work is completed, the wire reel brake rod 31 is returned to its position by a spring.

[0027] The jaw control linkage mechanism 11 includes a jaw control rod 3, a return spring 27, a push rod 28, a jaw linkage rod 26 and a jaw force rod 35. The jaw control rod 3 is connected to the jaw control linkage mechanism 11 through a jaw control line 5.

[0030] A groove is provided between the guide wheel 20 and the positioning wheel 21, a clamp brake 23 is provided on the outer side of the positioning wheel 21, two brake wires are connected to the guide wheel 20, and the front, rear, left and right spacing between the guide wheel 20 and the positioning wheel 21 can be adjusted by positioning bolts 19;

[0031] The guide wheels 20, the positioning wheels 21 and the walking and turning guide wheels 22 are each provided with two on the left and right sides, so as to facilitate flexible turning on the steel bar surface and walking in the dominant direction.

[0032] The diameter and assembly quantity of the wire disc mechanism 4 are adjustable, and the assembly quantity and spacing of the bundling components 7 are adjustable.

[0033] In this embodiment, the following operations are required to realize the automatic combined vehicle type high-efficiency steel bar bundling machine provided by the present invention:

[0034] The present invention is aimed at the bundling of floor slab reinforcements. The floor slab reinforcements are generally divided into upper layer reinforcements and lower layer reinforcements. The lower layer reinforcements are arranged on the ground, and a horse stool support is arranged between the upper and lower layer reinforcements to maintain a spacing.

[0035] Before starting to bundle, firstly, according to the needs of the construction, the lower layer of steel bars 36 to be bundled are neatly arranged in a cross-shaped manner at the designated position to form a number of steel bar intersections 37, and then, according to the spacing between the arranged steel bars 36 and the spacing between the formed steel bar intersections 37, the appropriate number of bundled components 7 are sequentially installed on the pitch-adjusting screw 8 and the pitch-adjusting slide bar 9, and then the mobile adjustment handbrake 17 on the single bundled component 7 that needs to be adjusted is closed so that the opening and closing nut 34 is matched with the pitch-adjusting screw 8, and then the pitch-adjusting screw crank 10 is turned to drive the single bundled component 7 to move to the designated position and then the mobile adjustment handbrake 17 is pulled open to separate the opening and closing nut 34 from the pitch-adjusting screw 8. At this point, the adjustment of the bundled component 7 is completed, and then each bundled component 7 can be adjusted to the designated position one by one in this way. After adjusting each bundled component 7, close the mobile adjustment handbrake 17 so that the opening and closing nut 34 fixes the bundled component 7. Then, the same number of wire reels 29 are arranged on the wire reel mechanism 4 according to the number of the bundling assemblies 7, and the wires of the wire reels 29 are passed around the pulley 32 on the wire reel brake rod 31 and connected to the single steel bar bundling machine 15, and then the single steel bar bundling machine 15 is respectively connected to the battery 13. After the bundling assembly 7 is adjusted, the spacing of the positioning wheels 21 is adjusted so that the two positioning wheels 21 touch the ground and walk, and then the distance between the positioning wheels 21 and the clamping claws 18 for grabbing the steel bars is adjusted so that when the positioning wheels 21 support the horizontally arranged steel bars 36, the clamping claws 18 for grabbing the steel bars are just aligned with the intersection 37 of the steel bars to be bundled, so as to prevent deviation from the direction during bundling. When bundling the lower layer of steel bars, the guide wheel 20 is not needed, and the guide wheel 20 can be pulled upward by the brake wire and hung on the upper guide wheel control handle 14, so that the guide wheel 20 is in a horizontal state, and the preparation work before bundling is completed.

[0036] Next, the staff pushes the push rod 1 to move the product to the previously placed steel bars 36 that need to be bundled, first bundle the steel bar intersection 37 on the outermost edge, and then gently presses down the push rod 1 to lift the bundling assembly 7 slightly. When the positioning wheel 21 supports the transversely arranged steel bars 36, pull the clamp control rod 3 to the positioning wheel brake switch 2. At this time, the positioning wheel 21 drives the clamp brake 23 through the brake line to brake it and stop it from moving. Then slowly lower the bundling assembly 7. When the push rod 28 touches the ground, it will push the clamp control connecting rod mechanism 11 upward, so that the clamp control connecting rod mechanism 11 drives the clamp linkage rod 26 to move upward together. At this time, the clamp 18 that grabs the steel bar will grab the steel bar intersection 37. When the clamp control connecting rod mechanism 11 touches the strapping machine limit switch 25, the matching multiple single steel bar strapping machines 15 start working at the same time to complete the bundling of the steel bar intersection 37. After the above bundling work is completed once, the whole bundling machine returns to the original state. At this time, the staff presses down the push rod 1, so that the positioning wheel 21 is lifted up and passes over the supported transversely arranged steel bars 36 to move to the next transversely arranged steel bars 36, and the above work is repeated to continuously complete the bundling work of the steel bar intersection 37. When it is necessary to bundle the lower layer of steel bars close to the inner bottom plate edge bars of the outer beam steel bars, a single steel bar bundling machine 15 on one side of the bundling machine main frame 6 can be installed and operated to avoid affecting the work due to the small distance between the edge bars and the outer beam steel bars.

[0037] When tying the upper layer of steel bars, it is necessary to release the guide wheel 20 from the upper guide wheel control handle 14, and use another brake line to pull the guide wheel 20 upward and hang it on the lower guide wheel control handle 14, so that the guide wheel 20 is in an inclined state, and adjust the spacing between the positioning wheels 21 and the guide wheels 20 respectively, so that the grooves on the positioning wheels 21 and the guide wheels 20 are pressed on the vertically arranged steel bars 36 to control the direction of operation during work. In addition, when tying the upper layer of steel bars, it is necessary to use the top rod connecting rod 33 to connect the two top rods 28. Because the upper layer of steel bars is a certain distance from the ground, the top rod 28 is not easy to touch the ground, so the top rod connecting rod 33 can be used to touch the steel bars to push the top rod 28 upward, thereby driving the clamping claw to control the connecting rod mechanism 11 to move upward, and then repeat the lower layer steel bar tying operation process to complete the tying work.

[0038] During operation, if the two top rods 28 are unstable in contact with the ground, a worker can assist in pulling up the clamp control rod 3 to drive the clamp control link mechanism 11 to move upward through the clamp control line 5, or a worker can step on the clamp force rod 35 to make the clamp control link mechanism 11 move upward, both of which can drive the clamp 18 that grabs the steel bars to grasp the steel bar intersection 37, and then touch the strapping machine limit switch 25 upward to start the single steel bar strapping machine 15, and complete the strapping work.
