This leads to reduced cutting accuracy and increased scrap rate. In addition, the existing device is not adaptable to steel strips of different thicknesses. When changing the specifications of the steel strip to be processed, a lot of time needs to be spent on manual adjustment, which seriously affects the processing efficiency.

[0005] Therefore, a feeding device for steel strip longitudinal shearing is proposed to address the above problems. Utility Model Content

While ensuring feeding stability, it also effectively reduces steel strip deviation, improves cutting accuracy, reduces scrap rate, and significantly shortens the adjustment time when changing steel strip specifications, thus significantly improving processing efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a feeding device for longitudinal shearing of steel strip, comprising a conveyor frame, a conveyor belt mounted on the inner surface of the conveyor frame, a fixed frame at the top of the conveyor frame, a feeding mechanism on the inner surface of the fixed frame, the feeding mechanism including a power motor fixedly connected to the fixed frame, a groove formed on the upper inner wall of the fixed frame, a bidirectional threaded rod rotatably connected to the inner walls of both sides of the groove, the output end of the power motor passing through one side of the fixed frame and fixedly connected to one end of the bidirectional threaded rod, and different shapes engraved on the outer surface of the bidirectional threaded rod.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figures 1 to 5 As shown, the feeding mechanism 5 includes a power motor 59 fixedly connected to the fixed frame 4. A groove 55 is provided on the upper inner wall of the fixed frame 4. A bidirectional threaded rod 57 is rotatably connected to both inner walls of the groove 55. The output end of the power motor 59 passes through one side of the fixed frame 4 and is fixedly connected to one end of the bidirectional threaded rod 57. Moving blocks 58 are threadedly fitted onto the threads in different directions on the outer surface of the bidirectional threaded rod 57. The connection between the power motor 59 and the bidirectional threaded rod 57 provides a precisely controllable power source for the feeding mechanism 5. By rotating the motor forward and backward, the bidirectional threaded rod 57 can be driven to rotate. Furthermore, by utilizing its threads in different directions, the two moving blocks 58 can be driven to move synchronously and in opposite directions, achieving precise adjustment of specific components of the feeding mechanism 5. Connecting rods 56 are rotatably connected to the inner surfaces of both moving blocks 58. A lifting plate 54 is rotatably connected to one end of each connecting rod 56. The two sides of the lifting plate 54 are slidably connected to the inner walls of both sides of the fixed frame 4. The height of the lifting plate 54 can be stably changed, thereby flexibly adjusting the relative position of the feeding mechanism 5 and the steel strip to meet the feeding requirements under different working conditions. Two sliding rods 53 are fixedly connected to the inner walls of both sides of the fixed frame 4. Several adjusting blocks 52 are slidably connected to the inner surfaces of the two sliding rods 53. Adjusting blocks 51 are fixedly connected to the middle of the outer surfaces of the two sliding rods 53. The sliding rods 53 provide a precise sliding track for adjusting blocks 52 and 51, so that they can maintain linearity and stability during movement, ensuring the accuracy and reliability of the feeding mechanism 5 when acting on the steel strip. Several guide grooves 542 are opened at one end of the lifting plate 54. One end of each adjusting block 52 is fixedly connected to a guide block 521 that works with the guide groove 542, which can guide the adjusting block 52 to move along a specific trajectory, further enriching the adjustment methods of the feeding mechanism 5 on the steel strip and enhancing the adaptability to steel strips of different specifications.

[0027] Specifically, both ends of the lifting plate 54 are fixedly connected with slide bars 541, and the inner walls on both sides of the fixed frame 4 are provided with slide rails 60 that cooperate with the slide bars 541. This effectively prevents the lifting plate 54 from shifting or shaking during the lifting process, greatly improves the stability of the movement of the lifting plate 54, and thus ensures the overall stability of the feeding mechanism 5.

[0028] like Figures 1 to 5As shown, the bottom ends of the two outermost adjusting blocks 52 each have two buffer grooves 524. The bottom ends of the four middle adjusting blocks 52 and adjusting block 51 are all equipped with feeding rollers 523. The feeding rollers 523 greatly reduce the friction of the steel belt during the conveying process, allowing the steel belt to be conveyed more smoothly and efficiently, thus improving the feeding efficiency. The upper inner walls of the four buffer grooves 524 are all fixedly connected with buffer springs 525, and the lower parts of the four buffer springs 525 are all fixedly connected with buffer rods 526. The bottom ends of the two corresponding buffer rods 526 are all fixedly connected with buffer blocks 522. The corresponding ends of the two buffer blocks 522 are all provided with positioning grooves 527, so that the buffer blocks 522 can always be in contact with the conveyor belt 2, effectively absorbing the impact force generated by the steel belt during the feeding process and protecting the steel belt from damage. The positioning grooves 527 on the buffer blocks 522 can play a positioning role for the steel belt, ensuring the positional accuracy of the steel belt during the feeding process.

[0029] Furthermore, several guide grooves 542 are inclined and mirror-distributed with the central axis of the lifting plate 54 as the axis of symmetry. This allows for more precise adjustment of the action on the steel strip according to different parameters such as the width and thickness of the steel strip, thereby improving the versatility and flexibility of the feeding device.

[0030] like Figures 1 to 5 As shown, two limiting grooves 528 are formed on the inner surface of the buffer groove 524, and a limiting block 529 that works with the two limiting grooves 528 is fixedly connected to the outer surface of the buffer rod 526. This limits the range of motion of the buffer rod 526 and prevents the buffer rod 526 from being excessively displaced or detached from the buffer groove 524 during the buffering process, thus ensuring that the buffer structure can work stably and reliably for a long time.

[0031] It is worth noting that the top of the conveyor frame 1 has two grooves 3, and the inner surfaces of the two grooves 3 are slidably connected to the fixed frame 4. The bottom of the conveyor frame 1 is threaded with two adjusting screws 31. The tops of the two adjusting screws 31 pass through the two grooves 3 respectively and are rotatably connected to the two sides of the bottom of the fixed frame 4, so that the height of the fixed frame 4 relative to the conveyor frame 1 can be easily adjusted to meet the feeding requirements of steel belts of different heights and enhance the applicability of the feeding device.

[0032] like Figures 1 to 5 As shown, each of the two adjusting screws 31 has an adjusting handle 32 installed at its bottom. By rotating the adjusting handle 32, the rotation of the adjusting screw 31 can be easily controlled, thereby realizing the manual adjustment of the height of the fixing frame 4. The operation is simple and labor-saving.

[0033] The power motor 59 is existing technology and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switch, which are not the main technical points of this patent and will not be described in detail. The wiring diagram of the motor in this utility model is common knowledge in the field, and its working principle is already known technology. The appropriate model is selected based on actual use; therefore, the control method and wiring layout of the motor will not be explained in detail.

[0034] Working principle and process: During operation, the steel belt is first placed on the conveyor belt 2, and the power motor 59 is started. The motor drives the bidirectional threaded rod 57 to rotate. Since the bidirectional threaded rod 57 drives the two moving blocks 58 to move in opposite directions, the moving blocks 58 drive the lifting plate 54 to make vertical lifting and lowering movements within the fixed frame 4 through the connecting rod 56. The guide groove 542 on the lifting plate 54 guides the guide block 521 on the adjusting block 1 52 to move, so that the adjusting block 1 52 slides on the slide rod 53 along a specific trajectory. At the same time, the adjusting block 2 51 is fixed in the middle position of the slide rod 53 and works in coordination with the adjusting block 1 52. The bottoms of the adjusting block 1 52 and the adjusting block 2 51 The feeding roller 523 works with the conveyor belt 2 to push the steel belt forward, reducing conveying friction. Under the action of the buffer rod 526 and the buffer spring 525, the buffer block 522 is always in contact with the conveyor belt 2, so that the positioning groove 527 on the buffer block 522 can position the steel belt. The limiting block 529 on the buffer rod 526 slides in the limiting groove 528 to prevent the buffer rod 526 from excessive displacement. If it is necessary to adjust the height of the feeding mechanism 5, the operator can rotate the two adjusting handles 32 at the same time to rotate the adjusting screw 31, thereby changing the height of the fixed frame 4 relative to the conveyor frame 1 to adapt to the feeding needs of steel belts of different heights.
