It can cut the galvanized steel sheet into strips of various required widths, and then collect the strips into small rolls for the next process.

[0003] In the process of longitudinal shearing of existing galvanized steel plates, the steel plates move through the upper and lower conveyor rollers, contact the longitudinal shearing tools in a rolling state, and are cut into strips. In the process of passing through the conveyor rollers, it is necessary to ensure the stability of the steel plates and prevent the steel plates from deflecting, otherwise it is easy to affect the accuracy of the specifications of the strips cut subsequently. Most of the existing methods of limiting the displacement of steel plates are to place positioning fixtures on both sides of the steel plates to implement position limiting operations on the steel plates. However, if there are burrs, bulges or other protruding structures on the edge of the steel plate, it is easy to rub against the surface of the fixture during its movement, causing wear of the fixture and jamming of the steel plate, affecting the efficiency of the longitudinal shearing of the steel plate.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example: Reference Figure 1 , Figure 2 The galvanized steel plate longitudinal shearing fixture shown includes a base 1, on which a driving roller 2 and a driving roller 3 are installed from top to bottom. The interlayer space formed by the driving roller 2 and the driving roller 3 can be used for the galvanized steel plate to pass through. After passing through the interlayer space, the galvanized steel plate can reach the bottom of the longitudinal shearing tools distributed in parallel. The longitudinal shearing tools descend to perform cutting operations on the galvanized steel plate.

[0022] A guide frame 4 for guiding the galvanized steel sheet is arranged on the front side of the transmission roller 2 3. Positioning rings 5 ​​that can rotate synchronously with the guide frame 4 are installed on the left and right ends of the outer surface of the guide frame 4. A plurality of correction blocks 6 arranged in a ring structure are arranged on the side of the positioning ring 5 close to the galvanized steel sheet. In the process of feeding the galvanized steel sheet, it is necessary to operate the galvanized steel sheet and place it on the surface of the guide frame 4. Then, as the guide frame 4 rotates, the galvanized steel sheet moves along the surface of the guide frame 4 to the inner side of the interlayer space formed by the transmission roller 1 2 and the transmission roller 2 3. In this process, the correction block 6 is always facing the edge of the galvanized steel sheet. The galvanized steel sheet can be quickly positioned, ensuring the accuracy of the position of the galvanized steel sheet when it moves through the interlayer space formed by the transmission roller 1 2 and the transmission roller 2 3 and contacts the longitudinal shearing tool, thereby improving the accuracy of the parallel longitudinal shearing tool in cutting the galvanized steel sheet.

[0023] like Figure 3As shown, the end of the correction block 6 away from the guide frame 4 is fixedly connected to a positioning plate 61, the surface of the positioning plate 61 is fixedly connected to a pressure spring 62, and the surface of the positioning ring 5 is provided with a plurality of accommodating cavities 51 for accommodating the pressure spring 62, and the inner wall of the accommodating cavity 51 is fixed to the end of the pressure spring 62 away from the correction block 6, the purpose of which is to provide elastic expansion and contraction potential energy for the correction block 6. In the process of feeding the galvanized steel sheet, if the edge of the galvanized steel sheet has burrs, bulges and other protruding structures, when the protruding structure contacts the correction block 6, the correction block 6 can be squeezed and contracted to avoid the protruding structure, leaving space for the protruding structure to move, effectively avoiding the obstruction of the protruding structure by the correction block 6, ensuring the smooth movement of the galvanized steel sheet, and improving the efficiency of the movement and shearing of the galvanized steel sheet.

[0024] The outer surface of the positioning ring 5 is connected to a plurality of limit plates 52 that can block the pressure spring 62 by screws. The limit plates 52 can effectively prevent the pressure spring 62 from swinging up and down, reduce the exposure of the pressure spring 62, and have a limiting and protective effect on the pressure spring 62.

[0025] like Figure 3 , Figure 4 As shown, the surface of the correction block 6 is provided with a channel, and a plurality of limit rollers 7 are connected to the inner side of the channel through a rotating shaft, and the ends of the limit rollers 7 are exposed from the channel. When the galvanized steel plate slides on the surface of the guide frame 4, the limit rollers 7 abut against the edge of the steel plate. The setting of the limit rollers 7 can effectively reduce the friction of the edge of the galvanized steel plate on itself, and further reduce the wear of the limit rollers 7 and the correction block 6 caused by the edge position of the galvanized steel plate during the movement. The limit rollers 7 can be replaced regularly, which prolongs the service life of the correction block 6.

[0026] The surface of the correction block 6 is provided with a gap for accommodating the edge of the guide frame 4. The correction block 6 is clamped to the end of the guide frame 4 through the gap, which can effectively prevent the correction block 6 from swinging and ensure the stability of the correction block 6.

[0027] like Figure 1 As shown, a positioning roller 8 is inserted into the inner side of the guide frame 4, and a transmission gear 11 and a transmission gear 2 12 are respectively installed at the ends of the positioning roller 8 and the transmission roller 2 3. The transmission gear 11 and the transmission gear 2 12 are meshed and connected with the same linkage gear 10, and a servo motor 19 adapted thereto is installed at the end of the linkage gear 10. When the servo motor 19 is powered on, the linkage gear 10 rotates under its driving potential energy. The transmission gear 11 and the transmission gear 2 12 are located on both sides of the linkage gear 10 and meshed therewith. When the linkage gear 10 rotates, the transmission gear 11 and the transmission gear 2 12 rotate in the same direction, so as to achieve the purpose of driving the positioning roller 8 and the transmission roller 2 3 to rotate synchronously, and the galvanized steel plate on the surface of the guide frame 4 can be smoothly transported.

[0028] like Figure 1 As shown, a servo motor 2 13 is installed just above the servo motor 19, a transmission gear 3 15 which can rotate synchronously with the transmission roller 2 is installed at the end of the servo motor 2, and a linkage gear 2 14 is installed at the end of the servo motor 2 13. The linkage gear 2 14 is meshed and connected with the transmission gear 3 15. In the natural state, the servo motor 19 and the servo motor 2 13 can respectively control the transmission gear 2 12 and the transmission gear 3 15 to rotate in opposite directions, so as to achieve the purpose of controlling the transmission roller 2 3 and the transmission roller 2 to rotate in opposite directions, and can smoothly clamp the galvanized steel plate and move it to the bottom of the longitudinal shearing tool.

[0029] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
