[0006] Furthermore, the straightening machine body includes a base plate, and a first vertical plate is fixedly installed on the top rear side of the base plate. Several first gears and second gears are arranged on the front side of the first vertical plate through a rotating shaft. The first gears are located above the second gears. The second gears and the first gears are arranged in a one-to-one correspondence and mesh with each other.

[0007] Furthermore, a third gear is rotatably arranged between two adjacent second gears, and the third gear meshes with the second gear. Positioning steel rings are fixedly arranged on both sides of the rotating shaft, and a steel bar straightening channel is formed between the positioning steel rings.

[0008] Furthermore, a support platform is provided below the second steel ring, and the support platform is fixedly installed at the bottom of the second steel ring, with the bottom of the support platform flush with the bottom of the base plate.

[0009] Furthermore, a second vertical plate is fixedly installed on the top front side of the base plate, a motor box is installed on the top of the base plate, a drive motor is fixedly installed inside the motor box, the motor box is made of thermally conductive material, heat sinks are fixedly installed on both sides of the lower end of the outer wall of the motor box, and the output end of the drive motor passes through the second vertical plate and is fixedly connected to one of the second gears.

[0027] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings, so that the advantages and features of this utility model can be more easily understood by those skilled in the art, thereby providing a clearer and more definite definition of the scope of protection of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] The terms "comprising" and "having," and any variations thereof, used in the specification, claims, and accompanying drawings of this utility model are intended to cover non-exclusive inclusion.

[0029] Please see Figure 1-8 A rebar limiting safety device for a rebar straightening machine includes a straightening machine body. A rebar limiting mechanism 12 is fixedly installed on one side of the straightening machine body. The rebar limiting mechanism 12 includes a first steel ring 121, which is fixedly installed on the outer wall of the straightening machine body. A discharge hole 11 for rebar output and a feed hole 18 for rebar input are provided on the other side of the straightening machine body. The discharge hole 11 is located inside the first steel ring 121. A second steel ring 123 is fixedly installed on the side of the first steel ring 121 away from the straightening machine body. The outer diameter of the second steel ring 123 is larger than that of the first steel ring 121. The outer diameter of the first steel ring 121 is such that several steel rods 122 are uniformly fixedly arranged in a ring on the side wall. The end of the steel rod 122 away from the first steel ring 121 is fixedly connected to the second steel ring 123. The gap between two adjacent steel rods 122 is less than 6cm. The steel bar enters the straightening machine body from the feed hole 18. When it passes through the steel bar limiting mechanism 12, the first steel ring 121, the second steel ring 123 and the steel rods 122 form a stable limiting effect on the steel bar, preventing the steel bar from swinging in a large range due to external force during the straightening process. This ensures that the steel bar can smoothly enter the straightening channel along the predetermined path and be output from the discharge hole 11 after straightening.

[0030] As an improvement to the above technical solution, the straightening machine body includes a base plate 7. A first vertical plate 5 is fixedly installed on the top rear side of the base plate 7. Several first gears 3 and second gears 4 are arranged horizontally on the front of the first vertical plate 5 via a rotating shaft 10. The first gears 3 are located above the second gears 4. The second gears 4 and the first gears 3 are arranged in a one-to-one correspondence and mesh with each other. A third gear 16 is rotatably arranged between two adjacent second gears 4 and meshes with the second gear 4. Positioning steel rings 17 are fixedly installed on both sides of the rotating shaft 10, forming a steel bar straightening channel between the positioning steel rings 17. A second vertical plate 6 is fixedly installed on the top front side of the base plate 7. A motor box 14 is installed on the top of the base plate 7. A drive motor is fixedly installed inside the motor box 14, and the output end of the drive motor passes through the second vertical plate 6. Plate 6 is fixedly connected to one of the second gears 4. The straightening machine body also includes a top plate 1, which is fixedly installed on the top of the first vertical plate 5. After the drive motor starts, its output end drives one of the second gears 4 to rotate. Since the second gear 4 meshes with the first gear 3, the first gear 3 rotates accordingly. At the same time, two adjacent second gears 4 mesh with each other through the third gear 16, so that multiple gears rotate in coordination to form a stable transmission system. When the steel bar passes through the steel bar straightening channel, it is squeezed and pulled by the first gear 3, the second gear 4 and the third gear 16, thereby realizing the straightening of the steel bar. A control panel 9 is fixedly installed on the top of the bottom plate 7. The control panel 9 is electrically connected to the drive motor. The start and stop of the drive motor can be easily controlled through the control panel 9.

[0031] As an improvement to the above technical solution, a support platform 15 is provided below the second steel ring 123. The support platform 15 is fixedly installed at the bottom of the second steel ring 123, and the bottom of the support platform 15 is flush with the bottom of the base plate 7. A mounting plate 13 is fixedly installed at the bottom of the drive motor. Threaded holes 8 are respectively provided through the four corners of the top of the mounting plate 13. Positioning screws are provided in the internal threads of the threaded holes 8. The positioning screws are threadedly engaged with the base plate 7. The mounting plate 13 is installed and fixed to the base plate 7 by the positioning screws. The motor box 14 is made of heat-conducting material, and the lower end of the outer wall of the motor box 14... Heat dissipation blocks 2 are fixedly installed on both sides. The support platform 15 provides stable support for the rebar limiting mechanism 12, ensuring that the rebar limiting mechanism 12 can remain stable during operation. The mounting plate 13 is installed and fixed to the base plate 7 by positioning screws, providing a solid mounting foundation for the drive motor and ensuring that the drive motor can operate stably during operation. The motor box 14 is made of heat-conducting material and has heat dissipation blocks 2 on the outside, which can effectively dissipate the heat generated by the drive motor during operation, prevent the motor from being damaged due to overheating, and ensure the normal operation of the motor.

[0032] The working principle and usage of this utility model:

[0033] In use, the reinforcing bars enter the straightening machine body through the feed hole 18, and enter the gear straightening area through the reinforcing bar straightening channel formed by the positioning steel ring 17. The control panel 9 starts the drive motor, and the motor output drives the second gear 4 to rotate. Through gear meshing, the first gear 3 and the adjacent third gear 16 are driven to rotate synchronously. The compression and guiding action between the gears is used to straighten the reinforcing bars. The straightened reinforcing bars are output from the discharge hole 11 and pass through the first steel ring 121, the second steel ring 123 and the ring-shaped distributed steel rods 122 to form a protective structure. The gap between adjacent steel rods is less than 6cm, which limits the swing range of the reinforcing bars and avoids affecting the straightening effect or damaging the equipment. The support platform 15 is fixed to the bottom of the second steel ring 123 and is flush with the base plate 7 to enhance the stability of the limiting mechanism. The motor box 14 is made of heat-conducting material and is used in conjunction with the heat sink 2 to achieve efficient heat dissipation of the drive motor. The drive motor is fixed to the base plate 7 by the mounting plate 13 and the positioning screw. The motor box 14 is easy to install and fix, ensuring the structural stability during operation.
