This novel design offers high shearing efficiency and improves production efficiency. However, its shortcomings are as follows:

[0004] Research and analysis revealed that although the device is equipped with positioning components for flat steel plates, the plates still require manual pushing to move, which is quite laborious. Furthermore, the positioning components are driven by independent motors to rotate independent rollers, which results in the overall component consuming a large amount of electricity during operation, making the device not energy-efficient or environmentally friendly.

[0020] 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.

[0021] Example 1:

[0022] Reference Figure 1-4 A positioning and feeding mechanism includes a flat steel shearing machine 1, a shearing table 101, a hydraulic cylinder 102, a shearing blade 103, and a guide table 2. The shearing table 101 is provided on the top of the flat steel shearing machine 1, and the shearing blade 103 is provided on the other side of the flat steel shearing machine 1 via the hydraulic cylinder 102. The guide table 2 is provided on the front of the shearing table 101. The outer side of the flat steel shearing machine 1 is provided with a guiding mechanism that can guide flat steel plates of different sizes and a driving mechanism that can drive the guide roller to rotate in an energy-saving manner.

[0023] The material guiding mechanism includes a lead screw slide rail 3, a slider 301, a guide shell 4, a movable seat 401, a guide roller 402, and a threaded rotating rod 404. The lead screw slide rail 3 is mounted on the top of the guide platform 2. A slider 301 is fitted to the outer side of the lead screw of the lead screw slide rail 3. The guide shell 4 is mounted on the top of the slider 301. A guide shell 4 is also mounted on the other side of the top of the guide platform 2 via a bracket. A movable seat 401 is movably mounted on the upper inner side of the guide shell 4 via a guide rod. Guide rollers 402 are rotatably mounted on the bottom of the movable seat 401 and the inner wall of the bottom of the guide shell 4. The connecting shaft on the other side of the guide roller 402 mounted on the inner wall of the bottom of the guide shell 4 is connected to the output shaft of an external motor. A threaded rotating rod 404 is threadedly connected to the top of the guide shell 4, and the front end of the threaded rotating rod 404 is connected to the movable seat via a bearing. The top of 401 is rotated. The operator adjusts the distance between the two guide shells 4 according to the width of the flat steel plate to be processed. By starting the motor of the lead screw slide rail 3, the lead screw of the lead screw slide rail 3 is driven to rotate. The rotating lead screw drives the slider 301 to move the guide shell 4 on one side, thereby completing the adjustment of the distance between the two guide shells 4. Then, the steel plate is placed between the two sets of guide shells 4. Then, the threaded rotating rod 404 is rotated to drive the movable seat 401 to move downward under the guidance of the guide rod. At the same time, the operator unscrews the bolts fixing the movable cavity 601 and the movable column 602, so that the movable column 602 moves in the movable cavity 601 to adjust the position of the upper bevel gear B603. When the two guide rollers 402 of one set are in contact with the two sides of the steel plate respectively, the adjustment is stopped.

[0024] Reference Figure 1-3 In this embodiment, the driving mechanism includes a bevel gear A5, a mounting bracket 6, a movable cavity 601, a movable column 602, and a bevel gear B603. The mounting bracket 6 is bolted to one side of the guide shell 4. The movable cavity 601 is rotatably mounted inside the mounting bracket 6 via a bracket. The movable column 602 is movably disposed inside the movable cavity 601, and the cross-section of the movable column 602 is cross-shaped. The inner cavity of the movable cavity is also cross-shaped. Bevel gears B603 are welded to the top of the movable column 602 and the bottom of the movable cavity 601. Bevel gears A5 are welded to the connecting shaft end on one side of the guide roller 402, and the bevel gears A5 extend to the guide shell 4. On the outside, the teeth of bevel gear A5 mesh with the teeth of bevel gear B603, and the upper bevel gear B603 meshes with the upper bevel gear A5. The bevel gears B603 and A5 at the top of the movable column 602 are meshed and driven by a right-angle drive. Then, the operator starts the motor on the other side of the guide roller 402 to drive the guide roller 402 to rotate. The rotating guide roller 402 drives the corresponding bevel gear A5 to rotate. Through the meshing transmission between bevel gear A5 and the corresponding bevel gear B603, the upper guide shell 4 rotates in the opposite direction. Thus, the two oppositely rotating guide shells 4 are used to position and guide the steel plate.

[0025] Reference Figure 1-4 , in this embodiment, an anti-slip block 403 is disposed on the surface of the material guiding roller 402 in a fitting manner.

[0026] Refer to Figure 1-4 , in this embodiment, the anti-slip block 403 is an anti-slip block 403 made of rubber. Since the rubber material has a large friction coefficient, using it as the material of the anti-slip block 403 can effectively increase the frictional force generated when the anti-slip block 403 contacts the surface of the flat steel plate, and thus can guide and convey the flat steel plate more efficiently.

[0027] Refer to Figure 1-4 , in this embodiment, the flat steel shearing machine 1, the hydraulic station supporting the hydraulic cylinder 102, the motor supporting the screw rod slide rail 3, and the external motor connected to the connecting shaft of the material guiding roller 402 are all connected to the supporting control panel, and the spacing of the sheet material shearing is marked by the staff in advance.

[0028] Working principle: First, the staff adjusts the spacing between the two material guiding shells 4 according to the width of the flat steel sheet to be processed this time. By starting the motor of the screw rod slide rail 3 to drive the screw rod of the screw rod slide rail 3 to rotate, the rotating screw rod drives the slider 301 to drive the material guiding shell 4 on one side to move, so as to complete the adjustment of the spacing between the two material guiding shells 4. Then, the steel sheet is placed between the two groups of material guiding shells 4, and then the threaded rotating rod 404 is rotated to drive the movable seat 401 to move downward under the guidance of the guiding rod. At the same time, the staff unscrews the bolts fixing the movable cavity 601 and the movable column 602, so that the movable column 602 moves in the movable cavity 601 to adjust the position of the upper bevel gear B603. When the two material guiding rollers 402 of a group respectively contact the two surfaces of the steel sheet, the adjustment is stopped. At this time, the upper bevel gear B603 meshes with the teeth of the upper bevel gear A5. After that, the staff starts the motor on the other side of the material guiding roller 402 to drive the material guiding roller 402 to rotate. The rotating material guiding roller 402 drives the corresponding bevel gear A5 to rotate, and drives the upper material guiding shell 4 to rotate reversely through the meshing transmission of the bevel gear A5 and the corresponding bevel gear B603, so as to perform the positioning and guiding transportation work on the steel sheet by using the two material guiding shells 4 rotating in opposite directions.

[0029] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
