[0033] Please see the appendix Figure 1-3This utility model provides an end-face flattening device for a sheet coil 50, comprising a flattening mechanism 10, a driving mechanism 20, a buffer assembly 30, and a base plate 40, wherein the flattening mechanism 10 is disposed on the base plate 40. First, it should be noted that in this application, "longitudinal" refers to the length direction along the base plate 40, and "transverse" refers to the width direction along the base plate 40. Unlike existing technologies where rewinding with a flattening machine can repair the coil shape, which is cumbersome, time-consuming, and labor-intensive, significantly increasing repair costs and affecting processing efficiency, this application addresses these shortcomings by providing an end-face flattening device for a sheet coil 50, as detailed below:

[0034] The flattening mechanism 10 includes two flattening units arranged opposite each other along the longitudinal direction. Each flattening unit includes a flattening part 110 and a movable part 120. The movable part 120 is movably connected to the base plate 40 along the longitudinal direction and has a vertical adjustment groove 121. The flattening part 110 is movably connected to the vertical adjustment groove 121 along the vertical direction. A flattening space for placing the plate roll 50 is formed between the two flattening parts 110. The buffer assembly 30 includes two buffer units arranged opposite each other along the transverse direction. Each unit includes a roller 310, a sleeve 320, an elastic element 330, and two bearing seats 340 arranged longitudinally opposite each other. The bearing seats 340 are fixed on the base plate 40. The two ends of the roller 310 are rotatably connected to the two bearing seats 340. The sleeve 320 is sleeved on the roller 310, and the elastic element 330 is connected between the two ends of the sleeve 320 and the two bearing seats 340. The driving end of the driving mechanism 20 is connected to the flattening part 110 to drive the two flattening parts 110 to move in opposite directions along the longitudinal direction.

[0035] Specifically, the plate coil 50 end face flattening device in this application includes a flattening mechanism 10, a driving mechanism 20, a buffer assembly 30, and a base plate 40. The base plate 40 is used for mounting the flattening mechanism 10, which is used to flatten and repair uneven ends of the plate coil 50. The driving mechanism 20 is used to drive the flattening mechanism 10 to move, thereby starting and stopping the flattening operation. During the flattening operation, the plate coil 50 may experience axial movement. Therefore, the buffer assembly 30 is required to adapt to the axial movement of the entire plate coil 50 and reduce surface damage, thereby ensuring product quality.

[0036] The flattening mechanism 10 includes two flattening units arranged longitudinally opposite each other. Each flattening unit includes a flattening part 110 and a movable part 120. The movable part 120 is movably mounted on the base plate 40, thereby realizing the opening and closing movement of the flattening part 110. It is worth mentioning that the movable part 120 is provided with a vertical adjustment groove 121, which is used for the vertically movable installation of the flattening part 110, so as to adapt to the adjustment of the vertical position of the flattening part 110. To ensure that the flattening parts 110 are aligned with the coaxial centerline of the sheet roll 50 before the flattening operation, the flattening effect at the ends is uniform and consistent. After adjusting the height of the flattening parts 110, the two flattening parts 110 are driven to move in opposite directions by the driving mechanism 20 to flatten the sheet roll 50 in the middle. When the flattening is completed or before the sheet roll 50 is installed, the two flattening parts 110 are driven to move in opposite directions by the driving mechanism 20 to form sufficient extrusion space for easy removal / placement of the sheet roll 50.

[0037] Furthermore, the buffer assembly 30 includes two buffer units arranged laterally opposite each other. Each buffer unit includes a roller 310, a sleeve 320, an elastic element 330, and two bearing seats 340 arranged longitudinally opposite each other. The roller 310 is used for placing the plate roll 50, and the bearing seats 340 are used for rotatably connecting the roller 310, so as to accommodate the slight rotational changes of the plate roll 50 when it is placed. The sleeve 320 is used to reduce wear between the plate roll 50 and the roller 310, and the elastic element 330 is used to achieve flexible positioning at both ends of the sleeve 320. When the extrusion section, etc., is uneven at the end face, When the plate coil 50 flattens and exhibits non-uniform convergence, a brief gap space is created. At this time, the plate coil 50 is prone to axial movement. Since the plate coil 50 is mounted on the sleeve 320, the axial movement of the plate coil 50 can be reduced by the flexible limiting of the elastic elements 330 at both ends. However, slight axial movement impact can be buffered and adapted to by the elastic potential energy of the elastic element 330. After buffering, it slowly recovers through elastic deformation, thus playing a buffering role and protecting the plate coil 50 from impact and wear, further ensuring the yield rate. In a preferred embodiment of this application, the elastic element 330 is a spring, which is easy to install and has good buffering performance.

[0038] In a preferred embodiment of the present invention, the sleeve 320 is located in the flattening space, and the length of the sleeve 320 is greater than the length of the plate roll 50.

[0039] It should be noted that, since the plate roll 50 is directly installed on the sleeve 320, in order to ensure better buffering performance, the length of the sleeve 320 must be greater than the length of the plate roll 50 so that the plate roll 50 is located between the two elastic elements 330.

[0040] In a preferred embodiment of the present invention, the flattening part 110 includes an adjusting plate 111 and a pressure plate 112. The pressure plate 112 is fixed on the adjusting plate 111, and the adjusting plate 111 is movably connected to the vertical adjusting groove 121 in the vertical direction.

[0041] It should be noted that the pressure plate 112 is used to contact the plate coil 50 for flattening. Since the plate coil 50 is usually uneven due to its axially protruding end, considering the flattening effect, preferably, the pressure plate 112 is circular, and the circle matches the axial end face of the plate coil 50. Furthermore, the outer diameter of the pressure plate 112 is larger than the outer diameter of the plate coil 50, thus ensuring proper flattening and avoiding areas that the pressure plate 112 cannot reach. The adjusting plate 111 is used for mounting the pressure plate 112. 1. It is movably connected vertically to the vertical adjustment groove 121 to facilitate vertical height adjustment. This adjusts the centerline of the pressure plate 112 to coincide with the centerline of the plate roll 50, ensuring uniform and consistent flattening contact surface. It is worth mentioning that the pressure plate 112 can be installed on the adjustment plate 111 by bolt connection. In this way, if the size of the plate roll 50 is too large and the pressure plate 112 cannot flatten it completely, it is easy to replace it with a larger pressure plate 112, thereby improving the applicability of the equipment.

[0042] In a preferred embodiment of the present invention, the movable part 120 includes two movable supports 122 arranged laterally opposite each other, each of the movable supports 122 having a vertical adjustment groove 121, and the movable supports 122 being movably connected to the base plate 40 in the longitudinal direction.

[0043] It is worth noting that the movable support 122 has sufficient height and the vertical adjustment groove 121 can be set close to the top, so that the flattening part 110 can be supported to a sufficient height position when installed. The vertical adjustment groove 121 needs to be opened in each movable support 122 to ensure that the two ends are synchronized when adjusting the height.

[0044] Furthermore, the base plate 40 has two longitudinal sliding grooves 410 arranged laterally opposite each other, and the movable support 122 is movably connected to the longitudinal sliding grooves 410.

[0045] It should be noted that the longitudinal groove 410 can be movably provided for the movable support 122 and can limit the sliding direction of the movable support 122, thus playing a guiding role; preferably, the cross-section of the longitudinal groove 410 is an inverted T-shape, which has a better guiding and limiting effect.

[0046] Further, the drive mechanism 20 includes a connecting plate 210 and two drive units 220 arranged laterally opposite each other. Each drive unit 220 includes a drive assembly 221 and a double-ended lead screw 222.

[0047] Each of the adjusting plates 111 has an internal threaded hole. The two ends of the double-ended lead screw 222 are respectively connected through the internal threaded holes of the two adjusting plates 111 and extend outward. The driving assembly 221 is installed on the connecting plate 210, and the driving end of the driving assembly 221 extends out of the connecting plate 210. The driving end of the driving assembly 221 is fixedly connected to one end of the double-ended lead screw 222.

[0048] It should be understood that the connecting plate 210 is used for mounting the drive unit 220. Each drive unit 220 includes a drive assembly 221 and a double-ended lead screw 222. The double-ended lead screw 222 can synchronously link the two flattening parts 110. Typically, the external threads at both ends of the double-ended lead screw 222 are one positive thread and one negative thread. Thus, by rotating the double-ended lead screw 222, the adjusting plates 111 connected to both ends can move in opposite directions. Therefore, for easy connection, each adjusting plate 111 is provided with an internal thread hole so that the two ends of the double-ended lead screw 222 can move in opposite directions. The ends are respectively connected through the internal threaded holes of the two adjustment plates 111 and extend outward, so as to be fixedly connected with the drive end of the drive assembly 221 that extends out of the connecting plate 210. It is worth mentioning that when the connecting plate 210 can be fixed to the external frame, the drive assembly 221 fixed on the connecting plate 210 drives the double-ended lead screw 222 to rotate. Since the adjustment plate 111 is fixed, the double-ended lead screw 222 rotates itself, causing the adjustment plates 111 at both ends (under the rotation of the threads) to slide longitudinally along the movable support 122.

[0049] The drive assembly 221 can be a combination of a hydraulic motor and a reducer to provide torque to the double-ended lead screw 222.

[0050] Furthermore, the flattening part 110 also includes a hydraulic cylinder 113, and the two ends of the adjusting plate 111 are longitudinally protruding outward to form protrusions 114, wherein the hydraulic cylinder 113 is fixed in the adjusting groove, and the top end of the hydraulic cylinder 113 is connected to the protrusions 114.

[0051] It should be noted that the hydraulic cylinder 113 is used to adjust the height of the adjusting plate 111, and protrusions 114 are formed on both ends of the adjusting plate 111 along the longitudinal direction to support the hydraulic cylinder 113. The top of the hydraulic cylinder 113 is connected to the protrusions 114, so that the height position of the adjusting plate 111 can be adjusted by the vertical extension and retraction of the hydraulic cylinder 113, thereby adjusting the height position of the pressure plate 112.

[0052] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
