[0001] The utility model relates to the technical field of steel plate processing, in particular to a steel plate guide pinch roller device with an automatic correction function. Background Art

[0002] Steel plate is a flat steel material made by pouring molten steel and pressing it after cooling. It is flat and rectangular and can be directly rolled or cut from wide steel strip. Steel plate is also one of the processed raw materials in the production of many parts.

[0003] When feeding the steel plate into the processing equipment, due to the weight and size of the steel plate itself, pinch rollers are mostly used for transportation for convenience. However, when using pinch rollers to transport the steel plate, it is easy for the steel plate to be unable to be aligned with the processing equipment due to inaccurate placement of the steel plate, which requires subsequent correction. In addition, during the transportation process, the steel plate may also be misaligned due to reasons such as the transmission speed and the friction coefficient between the steel plate and the pinch rollers.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0026] Reference Figure 1-Figure 5 A steel plate guide pinch roller device with automatic correction function includes a frame 1, a mounting base 2 is installed at the bottom of the frame 1, and a mounting hole is opened on the mounting base 2 to fix the frame 1 with bolts.

[0027] A supporting mechanism is provided at the bottom of the frame 1 to support the bottom of the steel plate; Figure 1 As shown, the support mechanism includes at least two parallel drive rollers 3, the ends of the drive rollers 3 are rotatably connected to the frame 1, and a first drive motor 4 is installed on one end of the drive roller 3. The first drive motor 4 is fixed to the frame 1 through a bracket, and the first drive motor 4 provides power for the rotation of the drive roller 3;

[0028] like Figure 4 and Figure 5As shown, each driving roller 3 is a hollow tube, and a bidirectional screw rod 6 is coaxially provided inside the driving roller 3, and the end of the bidirectional screw rod 6 is rotatably connected to the end of the driving roller 3, and a second driving motor 7 is installed on the end of the bidirectional screw rod 6 away from the first driving motor 4, and the second driving motor 7 is fixed on the fixing seat 8 through a bracket, and the fixing seat 8 is fixed on the end of the driving roller 3, and the second driving motor 7 provides power for the rotation of the bidirectional screw rod 6; and a slip ring for electrically connecting the second driving motor 7 is also provided on the end of the driving roller 3 close to the second driving motor 7, wherein the slip ring includes a stator 14 and a rotor 15, the stator 14 is coaxially fixed on the outer wall of the driving roller 3, the stator 14 is connected to the second driving motor 7 through a wire, and the rotor 15 is rotatably installed on the stator 14, and the rotor 15 is connected to the external power supply through a wire, so that the driving roller 3 will not cause the power supply wire of the second driving motor 7 to be wound and damaged during rotation, thereby ensuring the normal power supply of the second driving motor 7.

[0029] A number of spaced strip grooves 5 are provided on the outer wall of the driving roller 3, and the strip grooves 5 pass through the tube wall of the driving roller 3, and movable seats 9 are threadedly connected at both ends of the bidirectional screw rod 6. A connecting rod 10 is provided on the outer wall of the movable seat 9, and the other end of the connecting rod 10 corresponds to passing through the strip groove 5 and is connected to the annular limit seat 11, and the limit seat 11 is coaxially arranged on the outer wall of the driving roller 3. When the steel plate is placed on the driving roller 3, or when the driving roller 3 rotates and drives the steel plate placed thereon to move together, the limit seat 11 will approach the steel plate under the rotation of the bidirectional screw rod 6, and perform a centered extrusion operation on the steel plate, thereby correcting the position of the steel plate on the driving roller 3 to ensure that the steel plate always maintains precise correspondence with the equipment that processes it, so as to improve the processing effect of the steel plate.

[0030] Furthermore, the side of the connecting rod 10 is matched with the inner wall clearance of the strip groove 5 to limit the movement of the movable seat 9 on the bidirectional screw rod 6, so that the movable seat 9 can only maintain the ability to move in the straight direction to prevent the limit seat 11 from angular deflection and affecting the correction of the steel plate by the limit seat 11.

[0031] It should be noted that a plurality of spherical receiving grooves 12 are arranged at intervals along the edge of the limit seat 11. The receiving grooves 12 pass through the side of the limit seat 11, and balls 13 are built into the receiving grooves 12. In actual use, the opening radius of the receiving grooves 12 passing through the limit seat 11 is smaller than the radius of the balls 13, so that the balls 13 can be stably placed in the receiving grooves 12 while being able to rotate freely; when the limit seat 11 is close to the steel plate, the balls 13 will contact the side of the steel plate, thereby correcting the steel plate, and will not hinder the movement of the moving steel plate, so that the steel plate can continue to be transported during the correction process.

[0032] like Figure 2 and Figure 3 As shown, a downward pressing mechanism that presses on the top surface of the steel plate is provided at the top of the frame 1, and the downward pressing mechanism includes a support seat 17 whose end is bent downward in an "L" shape, and at least two parallel pressure rollers 16 are provided in the support seat 17, and the ends of the pressure rollers 16 are rotatably installed on the ends of the support seat 17; a connecting piece is provided at the top of the support seat 17, and a linear drive module 19 that drives the support seat 17 to rise and fall is installed on the top of the connecting piece, and the linear drive module 19 is fixed on the top of the frame 1. In actual use, the linear drive module 19 is one of an electric push rod, a hydraulic cylinder, and an air cylinder. Under the push of the linear drive module 19, the pressure roller 16 can be pressed on the top surface of the steel plate, so that the steel plate and the drive roller 3 are in close contact, so that the rotation of the drive roller 3 can stably drive the steel plate to move.

[0033] In order to improve the driving ability of the driving roller 3 on the steel plate, rough rubber pads are installed on the outer walls of the pressure roller 16 and the outer walls of the driving roller 3 to increase the contact friction between the steel plate and the driving roller 3 and the pressure roller 16, so that the driving roller 3 can better transport the steel plate.

[0034] Among them, the connecting part includes a connecting seat 18, which is fixed to the linear drive module 19, and a connecting shaft 21 slides through the connecting seat 18, the bottom of the connecting shaft 21 is fixed on the support seat 17, and a limiting plate 22 is installed on the top of the connecting shaft 21, and a compression spring 23 is also sleeved on the connecting shaft 21. While ensuring that the pressure roller 16 has sufficient downward pressure on the steel plate, it acts as a buffer for the pressure roller 16 pressing on the steel plate to prevent the linear drive module 19 from exerting too much downward pressure and directly braking the steel plate, thereby hindering the transportation of the steel plate and even causing overload and damage to the first drive motor 4.

[0035] Furthermore, a guide shaft 20 is provided parallel to the side of the linear drive module 19 , one end of the guide shaft 20 is fixed on the connecting seat 18 , and the other end of the guide shaft 20 slides through the frame 1 to guide the lifting and lowering of the pressure roller 16 .

[0036] Specifically, when in use, the steel plate is first placed on the driving roller 3, and then the second driving motor 7 is started, and the limit seat 11 is controlled to approach the steel plate to perform a position correction operation on the placement of the steel plate. Then the linear drive module 19 is turned on to press the pressing roller 16 on the steel plate, and the first driving motor 4 is started to start conveying the steel plate. During the conveying process of the steel plate, the second driving motor 7 can also be intermittently driven to operate, so that the limit seat 11 can periodically approach the steel plate, and the steel plate can be continuously and automatically corrected.

[0037] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
