Description

Technical Field

[0001] This utility model mainly relates to the field of road construction protection equipment technology, specifically a follow-up rebar binding and feeding mechanism. Background Technology

[0002] In the field of steel bar production, steel bar tying is the core process for constructing the steel bar skeleton, and its technological level directly affects the mechanical properties and structural stability of the finished steel bars. Existing equipment lacks precise control over the wire feeding tension and cannot flexibly adjust the clamping force according to the state of the wire spool, making it difficult to ensure stable wire feeding tension. At the same time, when guiding the wire to complete the tying action, there are problems such as inaccurate positioning and poor coordination, affecting the tying effect and efficiency. Utility Model Content

[0003] To achieve the above objectives, this utility model employs the following technical solution:

[0004] A follow-up rebar binding and feeding mechanism includes a mounting frame, a wire spool rotatably connected to the mounting frame near the top, the wire spool being wound with iron wire, a support frame fixedly mounted near the top of the mounting frame, a pressing rotary shaft fixedly mounted on the support frame, the pressing rotary shaft abutting against the outer ring of the wire spool, and a binding robot body fixedly mounted near the bottom of the mounting frame.

[0005] A U-shaped frame is fixedly installed on the support frame. The two ends of the clamping rotary shaft are rotatably connected to the U-shaped frame. Guide rods are symmetrically fixed at the ends of the U-shaped frame. The guide rods pass through the support frame and are slidably connected. Screws are symmetrically threaded on the support frame. The ends of the screws pass through the support frame and abut against the side of the U-shaped frame. A rotating shaft is rotatably installed on the mounting frame. The screw spool is sleeved on the rotating shaft.

[0006] The binding robot body includes a housing, a wire body, and a wire cover plate. The wire body is fixedly installed at the bottom of the housing. The wire cover plate is hinged to the wire body. A wire groove is fixedly installed at the bottom of the wire cover plate. A cutting head seat is fixedly installed at the bottom of the housing. A cutting head is fixedly installed inside the cutting head seat. The cutting head has symmetrically and alternately hinged cutting blades.

[0007] The wire cover plate is connected to the bottom of the housing by a torsion spring, and the wire groove is trapezoidal.

[0008] The mounting bracket has a groove, and the top of the housing has a through groove. The wire passes through the groove, the through groove, the cut-off head, and the wire groove in sequence.

[0009] Compared with the existing technology, the beneficial effects of this utility model are:

[0010] This utility model has a simple structure and is easy to install and use. By adjusting the clamping force of the clamping rotary shaft on the wire on the wire spool, precise control of the wire feeding tension is achieved, effectively ensuring the stability of the tension during the wire feeding process and avoiding problems such as loosening or knotting of the wire. The wire cover plate and the wire body are connected by a torsion spring, which allows the wire cover plate to apply stable pressure to the wire groove, tightly pressing the wire groove against the position where the rebar is to be tied. At the same time, the trapezoidal wire groove can guide the wire more accurately, making it fit the rebar precisely, significantly improving the positioning accuracy during the wire guiding process.

Detailed Implementation

[0016] The present invention will be further described in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.

[0017] Referring to the accompanying drawings, a follow-up rebar binding and feeding mechanism includes a mounting frame 1, a wire spool 2 rotatably connected to the mounting frame 1 near the top, the wire spool 2 being wound with iron wire, a support frame 3 fixedly mounted near the top of the mounting frame 1, a pressing rotary shaft 4 fixedly mounted on the support frame 3, the pressing rotary shaft 4 abutting against the outer ring of the wire spool 2, and a binding robot body 5 fixedly mounted near the bottom of the mounting frame 1.

[0018] A U-shaped frame 6 is fixedly mounted on the support frame 3. The two ends of the clamping rotary shaft 4 are rotatably connected to the U-shaped frame 6. Guide rods 9 are symmetrically fixed at the ends of the U-shaped frame 6. The guide rods 9 pass through the support frame 3 and are slidably connected. Screws 10 are symmetrically threaded on the support frame 3. The ends of the screws 10 pass through the support frame 3 and abut against the side of the U-shaped frame 6. A compression spring is sleeved on the screws 10. This structural design adjusts the clamping force of the clamping rotary shaft 4 on the wire spool 2. A rotating shaft 7 is rotatably mounted on the mounting frame 1. The wire spool 2 is sleeved on the rotating shaft 7.

[0019] The binding robot body 5 includes a housing 501, a wire body 502, and a wire cover plate 503. The wire body 502 is fixedly disposed at the bottom of the housing 501. The wire cover plate 503 is hinged to the wire body 502. A wire groove 504 is fixedly disposed at the bottom of the wire cover plate 503. A cutting head seat 505 is fixedly disposed at the bottom of the housing 501. A cutting head 506 is fixedly disposed inside the cutting head seat 505. Cutting blades 507 are symmetrically and alternately hinged on the cutting head 506.

[0020] The housing 501 is equipped with a wire feeding mechanism to pull and transport the iron wire.

[0021] The wire cover plate 503 is connected to the bottom of the housing 501 by a torsion spring 8, and the wire groove 504 is trapezoidal.

[0022] The mounting bracket 1 has a groove, and the top of the housing 501 has a through groove. The wire passes through the groove, the through groove, the cut-off head 506, and the wire groove 504 in sequence. This structural design guides the wire.

[0023] When using this device, the mounting frame 1 is installed on the external moving device, and the wire spool 2 is fitted on the rotating shaft 7 on the mounting frame 1. The wire spool 2 can rotate freely around the rotating shaft 7. The iron wire wound on it is used as the material for binding the reinforcing bars. By adjusting the screw 10 on the support frame 3, the distance between the U-shaped frame 6 and the support frame 3 is changed, thereby adjusting the pressure of the clamping rotating shaft 4 on the wire spool 2, so that the iron wire maintains appropriate tension during the wire feeding process and avoids the iron wire from becoming loose or knotted.

[0024] The mounting frame 1 is moved to the rebar binding position by an external moving device. When the binding operation begins, the wire is released from the wire spool 2 and passes through the groove on the mounting frame 1 and the through slot at the top of the housing 501 in sequence, and enters the cutting head 506 in the cutting head seat 505. The torsion spring 8 between the wire cover plate 503 and the wire body 502 keeps the wire cover plate 503 under certain pressure, pressing the wire groove 504 tightly in the position where the rebar is to be bound. The trapezoidal wire groove 504 can better guide the wire and make it accurately fit the rebar, which is convenient for subsequent binding operations.

[0025] The cutting head 505 drives the wire to wrap around the rebar. After the binding is completed, the external moving device drives the frame 1 to rotate, which in turn drives the binding robot body 5 to rotate. The symmetrically interlocked cutters 507 on the cutting head 506 twist the wire to break, completing one rebar binding operation.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
