[0002] A spring machine usually refers to mechanical equipment for producing springs. A correction device is installed at the feeding position on the spring machine. When the steel wire passes through the correction device during the feeding process, the steel wire is corrected. Patent announcement number CN220760857U discloses a feeding correction mechanism for a spring machine. Through the designed connection mechanism, the worn arc ring part on the correction wheel can be replaced separately during use, reducing replacement costs. Other parts on the correction wheel can also be reused, reducing material waste, facilitating replacement, and improving the use effect.

[0003] However, the above solution still has some shortcomings. Specifically, when the straightening wheel is damaged, the machine needs to be stopped for replacement, otherwise it will cause uneven force on the steel wire, which will lead to deformation problems. In addition, the existing design only relies on a fixed cleaning brush to remove impurities attached to the steel wire, which may not be able to completely remove all impurities.

[0018] Example: A feed correction mechanism for a spring machine, such as Figure 1-Figure 4As shown, it includes an installation shell 1, a slide rail 2, a slider a3, a bidirectional screw rod a4, a motor a5, a rotating shaft a6, a fixed plate 61, an extrusion wheel 62 and a limit plate 63. The installation shell 1 is a square shell with an opening on the front side, and grooves are provided on the left and right side panels to facilitate the steel wire to pass through the installation shell 1 from right to left. Four slide rails 2 are welded and fixed on the inner wall of the rear side panel of the installation shell 1 from left to right. Two sliders a3 are slidably provided on the two slide rails 2 on the outside. A bidirectional screw rod a4 is rotatably connected to the position near the two outer slide rails 2 between the upper and lower side panels of the installation shell 1. The two bidirectional screw rods a4 pass through the adjacent sliders a3 and are respectively threaded with them. The top of the installation shell 1 is fixed by Two motors a5 are installed with bolts, and the output shaft ends of the two motors a5 are fixedly connected to the upper ends of the two bidirectional screw rods a4 respectively. The four sliders a3 are all embedded with rotating shafts a6, and the four rotating shafts a6 are welded and fixed with fixed plates 61 near the positions of adjacent sliders a3. The four rotating shafts a6 are detachably slidingly provided with extrusion wheels 62. The front parts of the four rotating shafts a6 are all provided with threads, and are respectively connected with limit plates 63 through the threads. The limit plates 63 are used to limit and fix the extrusion wheels 62. Auxiliary components and cleaning components are also included. Auxiliary components for assisting in extruding the steel wire are provided on the two inner slide rails 2, and a cleaning component for cleaning the surface of the steel wire is provided on the right side of the installation shell 1.

[0019] like Figure 2 and Figure 3 As shown, the auxiliary component includes a slider b71, a bidirectional screw rod b72, a motor b73, a rotating shaft b74 and an auxiliary wheel 75. Two sliders b71 are slidably provided on the two inner slide rails 2. The positions between the upper and lower side panels of the mounting shell 1, which are located close to the two inner slide rails 2, are rotatably connected with the bidirectional screw rods b72. The two bidirectional screw rods b72 pass through the adjacent sliders b71 and are respectively threaded with them. Two motors b73 are installed on the top of the mounting shell 1 by bolts. The output shaft ends of the two motors b73 are respectively fixedly connected to the upper ends of the two bidirectional screw rods b72. The four sliders b71 are all embedded with rotating shafts b74, and the four rotating shafts b74 are all fixedly connected to the auxiliary wheels 75.

[0020] like Figure 2 and Figure 4As shown, the cleaning assembly includes a mounting plate 8, a fixed brush 81, a fixed sleeve 82, a rotating brush 83, a gear ring 84, a motor c85 and a gear 86. The mounting plate 8 is welded and fixed to the right side of the mounting shell 1, the fixed brush 81 is welded and fixed to the right part of the mounting plate 8, and the fixed sleeve 82 is welded and fixed to the left part of the mounting plate 8. The rotating brush 83 is rotatably connected in the fixed sleeve 82, and the gear ring 84 is welded and fixed on the rotating brush 83. The motor c85 is installed on the fixed sleeve 82 by bolts, and the output shaft end of the motor c85 is fixedly connected to the gear 86, and the gear 86 and the gear ring 84 are meshed with each other.

[0021] First, the staff passes the steel wire from right to left in sequence through the fixed brush 81, the rotating brush 83 and the mounting shell 1, and finally connects it to the spring machine on the left. Then, the two motors a5 are started, and the two motors a5 respectively drive the two bidirectional screw rods a4 to rotate, thereby driving the extrusion wheels 62 on the adjacent sliders a3 to approach each other, thereby performing preliminary extrusion correction on the passed steel wire. When the spring machine starts working, it will pull the steel wire to the left. During this process, the extrusion wheel 62 continues to correct the steel wire to ensure its straightness. At the same time, the staff starts the motor c85, and the motor c85 drives the rotating brush 83 to rotate through the meshing transmission of the gear 86 and the gear ring 84, brushing and cleaning the surface of the steel wire. When the steel wire passes through the fixed brush 81 and the rotating brush 83, the fixed brush 81 first sweeps off the loose impurities attached to the surface of the steel wire, and then the rotating brush 83 further cleans the more stubborn impurities attached to the surface of the steel wire, thereby making the surface of the steel wire cleaner. If it is necessary to replace the extrusion wheel 62 on the left, the staff first starts the motor b73 on the left. The motor b73 drives the bidirectional screw rod b72 to rotate, so that the two sliders b71 on the left are close to each other, and then drives the two auxiliary wheels 75 to approach each other and temporarily squeeze and fix the steel wire. At this time, the motor a5 on the left can be started and reversed to drive the two extrusion wheels 62 away from each other to make room for the replacement operation. In this way, the staff can replace the extrusion wheel 62 without stopping the machine, thereby ensuring work efficiency. Similarly, when it is necessary to replace the extrusion wheel 62 on the right, it is only necessary to start the motor b73 on the right first to make the two auxiliary wheels 75 on the right squeeze and fix the steel wire, and then perform the corresponding replacement operation.

[0022] like Figure 1 As shown, a rotating plate 9 is also included, and the rotating plate 9 is rotatably connected to the front side of the top of the installation shell 1.

[0023] By providing the rotating plate 9, the front side of the mounting shell 1 can be shielded, thereby protecting key components such as the extrusion wheel 62 and the bidirectional screw rod a4 in the internal space enclosed by the mounting shell 1 and the rotating plate 9, avoiding them from being directly affected by adverse external factors such as dust or accidental collisions, thereby extending their service life and reducing the risk of damage.

[0024] like Figure 3 As shown, it also includes a mounting block 10, a limiting rod 11 and a return spring 12. The mounting block 10 is welded and fixed on the right side of the top of the mounting shell 1. The limiting rod 11 is slidably provided on the upper part of the mounting block 10, and a return spring 12 is connected between the limiting rod 11 and the mounting block 10.

[0025] By setting the mounting block 10, the limit rod 11 and the return spring 12, when it is necessary to maintain the extrusion wheel 62 or install the steel wire, the staff pulls the limit rod 11 to the right. At this time, the return spring 12 is stretched, and then the rotating plate 9 is flipped upward. After releasing the limit rod 11, under the reset action of the return spring 12, the limit rod 11 moves to the left and resets, thereby limiting the rotating plate 9 to the upward flipped state, thereby effectively preventing the rotating plate 9 from suddenly flipping downward due to external factors, thereby improving the safety and convenience of operation.

[0026] like Figure 1 As shown, a protective shell 13 is also included, and the protective shell 13 is fixed to the top of the mounting shell 1 by bolts.

[0027] By providing the protective shell 13, the motor a5 and the motor b73 are protected inside the protective shell 13, reducing damage caused by accidental collision or impact, thereby ensuring the stable operation of the motor a5 and the motor b73 and extending their service life.
