[0042] It should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood broadly. For example, they can refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components.

[0043] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0044] Reference Figures 1 to 5, is an embodiment of the present invention, and proposes a tie rod blowing and plating device for blowing and plating the galvanized tie rod, comprising: a first guide plate 2, having a guide groove 201, in which the tie rod is slidably arranged, and the guide groove 201 is used to guide and limit the tie rod in the horizontal direction; a correcting rod 3, slidably arranged on one side of the guide groove 201, after the tie rod slides out of the guide groove 201, the side wall of the tie rod slides and abuts against the correcting rod 3; a second guide plate 10, which is arranged on the side of the correcting rod 3 away from the first guide plate 2, and the second guide plate 10 is used to guide and limit the tie rod in the vertical direction; a blowing and plating box 7, having a through groove 701, in which the tie rod is slidably arranged, and the blowing and plating box 7 is provided with an air duct 702, and the air duct 702 is used to blow and plate the tie rod located in the through groove 701.

[0045] In the above scheme, first, fix the first guide plate 2 in a suitable position to ensure the horizontality of the guide groove 201. The guide groove 201 allows the pull rod to slide smoothly in the guide groove 201. Next, install the correcting rod 3 on one side of the guide groove 201. The correcting rod 3 should be able to slide within a certain range to accommodate pull rods with different degrees of bending. Install the second guide plate 10 on the side of the correcting rod 3 away from the first guide plate 2 to ensure that the second guide plate 10 can guide and limit the pull rod in the vertical direction. Finally, install the blowing box 7 at the end of the entire device so that the pull rod can enter the blowing box 7 through the through groove 701 for blowing. The air duct 702 of the blowing box 7 is connected to the air source to provide sufficient wind force for blowing.

[0046] When the galvanized tie rod enters the device, it first enters the guide slot 201 of the first guide plate 2. The guide slot 201 provides horizontal guidance and positioning for the tie rod, ensuring stable horizontal movement. After the tie rod slides out of the guide slot 201, its sidewalls slide against the correcting rod 3. Due to the correcting rod 3, the bent tie rod is subjected to a correcting force during its sliding process, gradually straightening it. After passing the correcting rod 3, the tie rod continues forward and enters the guidance range of the second guide plate 10. The second guide plate 10 provides vertical guidance and positioning for the tie rod, further ensuring accurate movement. After guidance and correction, the tie rod passes through the through slot 701 and enters the blow plating box 7. The air duct 702 within the blow plating box 7 begins blow plating the tie rod within the through slot 701, removing excess zinc from the tie rod surface and smoothing the surface. During the blow plating process, the air flow and angle of the air duct 702 can be adjusted as needed to achieve the optimal blow plating effect. The coordinated action of the first guide plate 2, the deflection-correcting rod 3, and the second guide plate 10 ensures smooth entry of the tie rod into the plating chamber 7, avoiding difficulties associated with bent tie rods and improving plating efficiency. The deflection-correcting rod 3 effectively corrects bent tie rods, ensuring a more even distribution of wind force across the tie rod surface during plating, thereby ensuring plating quality and achieving a smoother, smoother surface. This device can accommodate tie rods of varying degrees of curvature, offering high versatility and wide application in various tie rod plating scenarios.

[0047] Furthermore, there are several guide grooves 201, and several guide grooves 201 are arranged at intervals on the first guide plate 2. There are several correcting rods 3, each correcting rod 3 corresponds to a guide groove 201, and each correcting rod 3 is located on one side of the corresponding guide groove 201. It also includes: a mounting seat 4, located between the first guide plate 2 and the second guide plate 10, and several correcting rods 3 are slidably arranged in the mounting seat 4; an arc-shaped plate 12, one end of which is hinged to the inner wall of the mounting seat 4, and the other end is slidably arranged on the inner wall of the mounting seat 4, the correcting rod 3 is arranged at the arc top of the arc-shaped plate 12, and the arc-shaped plate 12 is used to drive the correcting rod 3 to move; a hydraulic rod 11, which is arranged on the mounting seat 4, and the movable end of the hydraulic rod 11 is arranged at the end of the arc-shaped plate 12. After the hydraulic rod 11 pushes the arc-shaped plate 12 to compress and deform, the arc-shaped plate 12 drives the correcting rod 3 to squeeze and correct the pull rod located in the mounting seat 4.

[0048] In the above scheme, there are several guide slots 201 spaced apart on the first guide plate 2, allowing for simultaneous guidance of multiple pull rods, improving the operating efficiency of the device. There are also several correcting rods 3, each corresponding to a guide slot 201 and located on one side of the guide slot 201. This ensures that each pull rod has a corresponding correcting rod 3 to perform corrective operations after passing through the guide slot 201. The mounting base 4 is located between the first guide plate 2 and the second guide plate 10, providing space for the correcting rods 3 to be installed and slide. Several correcting rods 3 are slidably mounted within the mounting base 4, allowing them to flexibly move within the mounting base 4 to accommodate pull rods with varying degrees of curvature. One end of the curved plate 12 is hinged to the inner sidewall of the mounting base 4, while the other end is slidably mounted thereon. This connection allows the curved plate 12 to deform and move to a certain extent within the mounting base 4. The correcting rods 3 are located at the top of the curved plate 12, and when the curved plate 12 moves, they can drive the correcting rods 3 along with it. The curved plate 12 links the movement of the correcting rod 3 with the action of the hydraulic rod 11, achieving squeeze and corrective action on the tie rod. The hydraulic rod 11 is mounted on the mounting base 4, with its movable end positioned at the end of the curved plate 12. The hydraulic rod 11 acts as a power source, pushing the curved plate 12 to achieve the corrective action. When the hydraulic rod 11 compresses and deforms the curved plate 12, the curved plate 12 drives the correcting rod 3 to compress and correct the tie rod within the mounting base 4. The force of the hydraulic rod 11 can be adjusted based on the degree of bend in the tie rod, ensuring effective correction without damaging the tie rod. When the galvanized tie rod slides out of the guide slot 201 of the first guide plate 2 and enters the mounting base 4, if the tie rod is bent, the hydraulic rod 11 pushes the curved plate 12 based on the detected degree of bend. The curved plate 12 compresses and deforms under the action of the hydraulic rod 11, driving the correcting rod 3 toward the tie rod. The correcting rod 3 compresses the bent tie rod, gradually straightening it. The design of multiple sets of guide grooves 201 and correcting rods 3 improves the device's processing capacity, enabling simultaneous guidance and correction of multiple tie rods, making it suitable for large-scale production. The hydraulic rod 11 provides powerful power, while the curved plate 12 evenly transmits this power to the correcting rods 3, ensuring stable correction. The entire device boasts a compact structure, and the presence of the mounting base 4 stabilizes the movement of the correcting rods 3, reducing secondary damage to the tie rods caused by shaking during the correction process.

[0049] Furthermore, the mounting seat 4 has a feed port 401 and a discharge port 402. The feed port 401 is located on the side of the mounting seat 4 close to the first guide plate 2, and the discharge port 402 is located on the side of the mounting seat 4 close to the second guide plate 10. After the correcting rod 3 moves, the feed port 401 and the discharge port 402 cooperate with the correcting rod 3 to extrude and correct the pull rod.

[0050] In the above scheme, when the correcting rod 3 moves under the action of the hydraulic rod 11 and the curved plate 12, the feed port 401 and the discharge port 402 cooperate with the correcting rod 3 to squeeze and correct the pull rod. Specifically, after the pull rod enters the mounting seat 4 from the feed port 401, if there is any bending, the correcting rod 3 will approach the pull rod at the appropriate time. At this time, the edges of the feed port 401 and the discharge port 402 together with the correcting rod 3 form a clamp-like structure, which squeezes the pull rod in all directions. This squeezing effect can effectively correct the bending of the pull rod, so that it gradually becomes straight as it passes through the mounting seat 4, and can closely cooperate with the correcting rod 3 when the correcting rod 3 moves, thereby achieving effective squeezing of the pull rod. At the same time, their position and shape will also affect the effect and efficiency of the correction. The edges of the feed port 401 and the discharge port 402 can play a certain guiding role for the pull rod, preventing the pull rod from deflecting or shaking during the correction process. At the same time, their cooperation with the correction rod 3 also increases the overall stability of the device, reducing the risk of correction failure or equipment damage caused by unstable pull rod.

[0051] Furthermore, the second guide plate 10 is L-shaped and has a limiting surface, which is arranged horizontally and is used to limit and guide the pull rod in a vertical direction.

[0052] In the above scheme, the second guide plate 10 is set upside down, and the second guide plate 10 has a limiting surface, which is arranged horizontally. This horizontally arranged limiting surface limits and guides the pull rod in the vertical direction. After the pull rod is initially corrected by the correction rod 3, it enters the guiding range of the second guide plate 10. The limiting surface limits the movement of the pull rod in the vertical direction by contacting the pull rod, ensuring that the pull rod maintains a stable position in this direction. This is very important for the subsequent blowing process, because only when the pull rod remains stable in the vertical direction can the air duct 702 in the blowing box 7 evenly blow-plate the pull rod to ensure the quality of blowing. The L-shaped structure and horizontal limiting surface of the second guide plate 10 provide additional stability for the entire device. Ensure that the pull rod maintains a stable state of movement throughout the blowing process, reducing failures and defective product rates caused by shaking or offset.

[0053] Furthermore, it also includes: a roller 5, which is rotatably arranged on the side of the second guide plate 10 away from the first guide plate 2; a plurality of traction wheels 6, which are arranged in an array on the roller 5, and a groove 601 is formed between two adjacent traction wheels 6, each groove 601 is arranged corresponding to a guide groove 201, and the groove 601 is used to accommodate the pull rod.

[0054] In the above scheme, each groove 601 corresponds to a guide groove 201. This ensures that the pull rod exiting the guide groove 201 accurately enters the corresponding groove 601. The grooves 601 accommodate the pull rod, allowing it to continue moving forward under the action of the roller 5 and the traction wheel 6. The size and shape of the grooves 601 are designed to match the pull rod, ensuring stable movement within the grooves without causing excessive compression or wear. The traction wheel 6, in conjunction with the roller 5, generates traction on the pull rod, enabling it to be smoothly transferred from one process step to the next. The rotation of the traction wheel 6 drives the pull rod forward, ensuring the continuity and efficiency of the entire blow plating process. The combined design of the roller 5 and traction wheel 6 significantly improves the efficiency of the pull rod's transfer. The rotation of the roller 5 reduces friction between the pull rod and other components, while the traction of the traction wheel 6 ensures the pull rod's rapid and stable movement. The corresponding arrangement of the grooves 601 and the guide grooves 201 ensures the accuracy of the pull rod's transfer. The pull rod can accurately enter the corresponding groove 601, avoiding transmission failure or plating quality problems caused by position deviation.

[0055] Furthermore, it also includes: a base 1, having a feed side 102 and a discharge side 103, a first guide plate 2, a mounting seat 4, a second guide plate 10, a traction wheel 6 and a blowing box 7 are arranged on the base 1 in sequence along the direction from the feed side 102 to the discharge side 103.

[0056] In the above scheme, the first guide plate 2, the mounting seat 4, the second guide plate 10, the traction wheel 6 and the blowing box 7 are arranged on the base 1 in sequence from the feed side 102 to the discharge side 103. First, the pull rod enters the device from the feed side 102 and passes through the horizontal guide limit of the first guide plate 2 to ensure that the pull rod maintains stable movement in the horizontal direction. Then, the pull rod enters the mounting seat 4 and is corrected for bending under the action of the correction rod 3. Then, the corrected pull rod enters the guide range of the second guide plate 10 and is guided in the vertical direction by the limiting surface. After that, the pull rod reaches the traction wheel 6, and the traction wheel 6 pulls the pull rod through the groove 601, so that the pull rod can move forward smoothly. Finally, the pull rod enters the blowing box 7 for blow plating treatment to remove excess zinc liquid on the surface and make the surface of the pull rod smoother.

[0057] Furthermore, it also includes: a deflection frame 8, which is arranged on the base 1 and located on the feed side 102; a pressure roller 9, which is rotatably arranged on the deflection frame 8, and the pressure roller 9 is used to press the pull rod into the guide groove 201.

[0058] In the above solution, the pressure roller 9 is used to press the tie rod into the guide groove 201. When the tie rod enters the device from the feed side 102, it may be positioned incorrectly or fail to enter the guide groove 201 smoothly. The presence of the pressure roller 9 ensures that the tie rod accurately enters the guide groove 201 of the first guide plate 2. When the tie rod approaches the feed side 102, the pressure roller 9 presses the tie rod downward into the guide groove 201 through its own gravity or by applying a certain amount of pressure. This ensures that the tie rod is in the correct position before entering the subsequent processing steps, providing an excellent foundation for subsequent operations such as guiding, deflection correction, and blow-coating. The automatic pressing function of the pressure roller 9 reduces manual intervention and improves the automation level of the device. Manual insertion of the tie rod into the guide groove 201 is no longer necessary, reducing labor intensity and improving production efficiency. By accurately pressing the tie rod into the guide groove 201, the tie rod is guaranteed to remain in the correct position throughout the subsequent processing. This helps improve the accuracy of operations such as guiding, deflection correction, and blow-coating, thereby ensuring the processing quality of the tie rod. The pressing roller 9 can adapt to pull rods of different sizes and shapes. By adjusting parameters such as the position, pressure and rotation speed of the pressing roller 9, the processing requirements of pull rods of different specifications can be met, thereby improving the adaptability and versatility of the device.

[0059] Furthermore, a slide groove 101 is provided on the outer wall of the base 1, and the deflection frame 8 includes: a support rod 801, which is arranged on the outer wall of the base 1; a deflection rod 802, one end of which is hinged to the support rod 801, and the pressure roller 9 is arranged at the other end of the deflection rod 802; a traction rod 803, one end of which is hinged to the middle part of the deflection rod 802, and the other end is hinged to the sliding arrangement in the slide groove 101. After the traction rod 803 slides along the slide groove 101, the traction rod 803 drives the deflection rod 802 to deflect.

[0060] In the above scheme, when the position of the pressure roller 9 needs to be adjusted, the traction rod 803 is slid within the chute 101 by an external power device or manual operation. The sliding direction and distance of the traction rod 803 within the chute 101 can be controlled according to actual needs. When the traction rod 803 slides within the chute 101, since one end of the traction rod 803 is hinged to the middle of the deflection rod 802 and the other end slides within the chute 101, a pulling force or a pushing force is generated on the deflection rod 802. Under the action of the traction rod 803, the deflection rod 802 deflects around the support rod 801. Depending on the sliding direction of the traction rod 803 and the magnitude of the force, the deflection rod 802 can be deflected in different directions by a certain angle. The deflection of the deflection rod 802 drives the pressure roller 9 to move, thereby changing the relative position between the pressure roller 9 and the guide groove 201, and realizing the pressing or releasing operation of the pull rod. By sliding the traction rod 803 within the chute 101, the deflection angle of the deflection rod 802 can be precisely adjusted, thereby controlling the position of the pressure roller 9. This adjustability allows the device to adapt to pull rods of different sizes and shapes, improving the versatility of the device. The sliding operation of the traction rod 803 within the chute 101 is relatively simple and can be achieved through mechanical devices, hydraulic systems, or manual operation. This operation method is convenient and fast, and can improve production efficiency. The hinged connection between the support rod 801, the deflection rod 802, and the traction rod 803, as well as the guiding effect of the chute 101 on the traction rod 803, ensure that the deflection frame 8 has high stability during operation. The pressure roller 9 can stably press the pull rod into the guide groove 201, ensuring the normal operation of the device.

[0061] Furthermore, a guiding slope 202 is provided at the top of the guiding groove 201 , and the guiding groove 201 is U-shaped, so that the pull rod can easily enter the guiding groove 201 .

[0062] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
