[0002] In the mold steel bar production workshop, long mold steel bars need to be straightened during the forming process. Traditional straightening machines often require manual feeding, necessitating frequent material handling and placing a heavy workload on operators. Furthermore, long workpieces are prone to swaying and tailing when entering the straightening machine and during the straightening process, posing a significant safety hazard to workers near the machine. Moreover, current bar straightening machines lack limiting mechanisms after the bars enter, allowing them to easily shift position, affecting straightening efficiency and effectiveness. Simultaneously, the tailing of the bars can cause impact damage to the roller conveyor. Utility Model Content

[0023] See Figures 1-5This utility model relates to a feeding and conveying device for a straightening machine, comprising a frame. Further, the frame consists of two parallel channel steel beams 2 and several supporting legs 1. Several lifting V-shaped rollers 9 are sequentially arranged on the frame, forming a power conveying roller track. Each lifting V-shaped roller is individually equipped with a roller drive mechanism, and all lifting V-shaped rollers are driven by a single lifting mechanism for lifting action. Furthermore, the roller surface of the lifting V-shaped rollers in this utility model has a V-shaped structure and is covered with a nylon rubber layer. A protective layer is also provided in the gap between every two lifting V-shaped rollers. Each protective sleeve is mounted on the frame via a base mounting base 16. All protective sleeves are arranged coaxially and along the conveying direction of the lifting V-shaped roller. When the lifting V-shaped roller rises to convey steel, the workpiece passes through the protective sleeve. The protective sleeve near the entrance of the straightener is set as a cylindrical protective sleeve 6, and the protective sleeve away from the entrance of the straightener is set as a C-shaped protective sleeve 5. Furthermore, the cylindrical protective sleeve in this utility model is a hollow cylindrical shape, and its inner wall is provided with a nylon liner 14. The cross-section of the C-shaped protective sleeve is C-shaped, and the notch of the C-shape is set obliquely upward and outward. The inner wall of the C-shaped protective sleeve is also provided with a nylon liner.

[0024] Furthermore, each set of roller drive mechanisms in this utility model includes a drive shaft 8, with support arms 4 fixedly mounted at both ends of the drive shaft. The lifting V-shaped roller 9 is arranged between the two support arms. A sprocket and chain mechanism 15 and a drive motor 7 are arranged on the outer side of one of the support arms. The sprocket and chain mechanism is connected to the roller shaft of the corresponding lifting V-shaped roller. The drive motor drives the corresponding lifting V-shaped roller to rotate through the sprocket and chain mechanism. All drive shafts are simultaneously connected to the lifting mechanism. The lifting mechanism realizes the synchronous lifting and lowering of the lifting V-shaped roller by synchronously driving all drive shafts.

[0025] Furthermore, the lifting mechanism described in this utility model includes a drive cylinder 3 hinged to the bottom of the frame and a power rod 12. Each lifting V-shaped roller is provided with a hinge block 11 on the power rod, and a connecting rod 10 is hinged to each hinge block. One end of the connecting rod is rotatably connected to the corresponding hinge block, and the other end of the connecting rod is fixedly connected to the middle part of the corresponding drive shaft. The connecting rod drives the drive shaft to rotate. A drive arm 13 is also provided at the bottom of one of the hinge blocks. The drive arm is obliquely arranged and its lower end is hinged to the piston rod end of the drive cylinder. The drive arm is fixed to the bottom of the corresponding hinge block.

[0026] Furthermore, the hinge block described in this utility model is a rectangular frame structure, and the corresponding connecting rod end is connected to the rectangular frame structure through a rotating shaft.

[0027] This device works in conjunction with an automatic feeding system for automatic material feeding. As the lifting V-roll rises, it conveys round steel bars into the straightening machine. Upon entry, it immediately descends to protect the V-roll. C-shaped and round protective sleeves protect both the steel and the workers.

[0028] In use, this utility model is installed in front of the workpiece inlet of the straightening machine. During loading, the workpiece is placed into the C-shaped protective sleeve through the gap using a crane. At this time, all the lifting V-shaped rollers rise synchronously, supporting the steel bar workpiece, and all the drive motors are started. The drive motors drive the corresponding lifting V-shaped rollers to rotate through the sprocket and chain mechanism, thereby conveying the steel bar workpiece forward. During the conveying process, the steel bar workpiece passes through the C-shaped protective sleeve and the circular protective sleeve in sequence, and finally enters the inlet of the straightening machine through the circular protective sleeve. During the forward conveying process, the steel bar is protected by the C-shaped protective sleeve and the circular protective sleeve, so even if the steel bar jumps on the roller conveyor, the safety of the surrounding workers is guaranteed.

[0029] Once the steel bar workpiece enters the straightening machine, the lifting V-roller can be lowered immediately to prevent collision damage to the roller conveyor. During operation, the surface of the steel bar will not be damaged by collisions due to the nylon lining on the inner wall of the C-shaped and round sleeves, thus protecting the workpiece.

[0030] In this invention, the lifting action of the lifting V-shaped roller is achieved through a lifting mechanism, as detailed in the appendix. Figure 4 As shown, the piston rod of the drive cylinder moves, which in turn drives the hinge block on the power lever to move left and right through the drive arm. The movement of the hinge block then drives the connecting rod, which in turn drives the drive shaft to rotate. The rotation of the drive shaft will cause the support arms at both ends to rotate. The rotation of the support arms will then drive the lifting V-roller to move up and down. The whole system is linked, and the lifting V-roller moves up and down synchronously.

[0031] This invention utilizes a synchronously lifting V-shaped roller to form a conveyor roller track. Once the steel bar enters the straightener, the conveyor roller track formed by the lifting V-shaped roller immediately descends, protecting the roller track and extending its service life. This invention also features multiple protective sleeves sequentially installed on the frame, each with a nylon lining on its inner wall to prevent scratches and abrasions to the surface of the steel bar. The protective sleeves, including cylindrical and C-shaped sleeves, are arranged sequentially on the frame. The C-shaped sleeves facilitate the loading of the steel bar while providing guidance, while the cylindrical sleeves, positioned at the entrance of the straightener, offer enhanced safety protection when the steel bar enters the straightener.
