[0002] In the industrial production of precast concrete slabs, steel bars are the core and important structural reinforcement for load-bearing. During the production and processing of steel bars, in order to better package and transport them, multiple steel bars need to be wrapped and tightened with wire to achieve the binding operation. In this binding process, an automatic steel bar binding equipment for precast concrete slabs is required.

[0003] However, due to the poor binding adjustment capability of existing automatic steel bar binding equipment for precast concrete slabs, it is not convenient to bind multiple steel bars of different quantities according to binding needs during actual use. The existing equipment can only bind a single binding specification, which affects the efficiency of binding processing. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This automatic rebar tying equipment for precast concrete slabs uses a PLC controller to control the extension and retraction of hydraulic cylinders. The adjustable push rod can drive the installation support frame to move up and down, thereby adjusting the height of the positioning rings. This facilitates the tying of rebars of different diameters and heights. The bidirectional adjusting screw, driven by the second motor, drives two sliding limit screw blocks to move relative to or in opposite directions along the thread direction of the bidirectional adjusting screw, thereby adjusting the spacing of the positioning rings. It can adapt to the tying needs of rebars of different diameters and different combinations of quantities. Compared with the single tying specifications of traditional equipment, it greatly improves the equipment's versatility and processing efficiency.

[0015] 2. This automatic rebar binding equipment for precast concrete slabs uses a first motor to drive the mounting support frame to rotate, causing the positioning ring to rotate and wind the two ends of the wire to bind the rebar. A third motor drives the transmission roller to rotate, which can realize the automatic feeding of the rebar, reduce manual intervention, and effectively shorten the processing cycle of precast slab rebar compared with manual binding.

A second motor 407 is mounted on the side of the mounting support frame 405 away from the reinforcing L-shaped bracket 2 and is electrically connected to the PLC controller 3. A bidirectional adjusting screw 408 is mounted on the output shaft end of the second motor 407, extending into the limit groove 406. A movable connecting block 409 is fixedly installed on the inner wall of the part of the device 06 away from the second motor 407. The side of the bidirectional adjusting screw 408 away from the second motor 407 is rotatably connected to the movable connecting block 409. The outer end of the bidirectional adjusting screw 408 is threadedly connected to two sliding limit screw blocks 410. The bottom end of the two sliding limit screw blocks 410 is fixedly installed with an adjusting support rod 411. The bottom end of the adjusting support rod 411 is fixedly installed with a positioning ring 412. The hydraulic cylinder 401 is started to drive the adjusting push rod 402 to rise, and at the same time, it drives the positioning ring 412 to rise. At the same time, the second motor 407 is started to rotate the bidirectional adjusting screw 408, so that the sliding limit screw blocks 410 move relative to each other on the bidirectional adjusting screw 408, and drive the positioning ring 412 to come closer, bringing the two ends of the wire closer together. At the same time, the first motor 404 is started to drive the mounting support frame 405 to rotate. When rotating, it drives the positioning ring 412 to rotate, and at the same time, it winds the two ends of the wire.

[0024] A support groove 5 is provided on the side of the reinforced L-shaped bracket 2 near the support connecting plate 403. A connecting rod 6 is installed on the side of the support connecting plate 403 near the support groove 5. The connecting rod 6 is movably connected inside the support groove 5. Positioning racks 7 are installed on the two sides of the top of the equipment base 1 that are far apart. A transmission U-shaped seat 8 is installed on one side of the top of the equipment base 1. A third motor 9 is installed on the side of the transmission U-shaped seat 8 away from the reinforced L-shaped bracket 2. The third motor 9 is electrically connected to the PLC controller 3. A transmission roller 10 is installed on the output shaft end of the third motor 9.

The third motor 9 is started to drive the transmission roller 10 to rotate, and the steel bar bundle is conveyed through another auxiliary transmission roller 10.

[0025] Working principle: When it is necessary to tie the reinforcing bars for the production of precast concrete slabs, first, the device is stably placed in the required position, and an external power supply is connected to power the equipment on the device. Then, multiple reinforcing bars are placed on two positioning frames 7 and on the transmission rollers 10 to limit their placement. Then, the hydraulic cylinder 401 is activated to push the adjusting rod 402 down, and at the same time, the positioning ring 412 is pushed down to both sides of the wire placement seat 11, so that the adjusting support rod 411 is located on both sides of the reinforcing bars. The wire is passed through the positioning ring 412 and positioned below the reinforcing bars. Then, the hydraulic cylinder 401 is activated again to drive the adjusting rod 402 up, and at the same time, the positioning ring 412 is driven up. When the positioning ring 412 rises, it drives the two ends of the wire upwards. The wire is lifted and the reinforcing bars are wrapped around it. At the same time as it rises, the second motor 407 is started to rotate the bidirectional adjusting screw 408, so that the sliding limit screw 410 moves relative to the bidirectional adjusting screw 408, causing the positioning ring 412 to come closer and bringing the two ends of the wire closer together. At the same time, the first motor 404 is started to drive the mounting support frame 405 to rotate. When rotating, the positioning ring 412 rotates, and the two ends of the wire are wrapped around it, completing the binding operation of multiple reinforcing bars. After binding one end of the reinforcing bar, the third motor 9 is started to drive the transmission roller 10 to rotate, and the reinforcing bar bundle is conveyed through another auxiliary transmission roller 10, conveying the reinforcing bar to the side of the wire placement seat 11. After being conveyed to the appropriate position, the above operation procedure is repeated to carry out the binding operation.
