In one embodiment, the pulling mechanism 3 comprises a moving platform 3-1 and a pulling roller group 3-2, a sheet material 101 extending from the coiled material 100 is laid on the surface of the moving platform 3-1, the pulling roller group 3-2 is positioned between the moving platform 3-1 and the upper material rack 1, the pulling roller group 3-2 is used for pulling out the sheet material 101 in the coiled material 100, the sheet material 101 is wound on the pulling roller group 3-2, and through the rotation of the pulling roller group 3-2, the sheet 101 can be sent to the moving platform 3-1, so that the sheet 101 extending from the coil 100 can be smoothly laid on the surface of the moving platform 3-1, wherein, the moving platform 3-1 can send the sheet stock 101 to the feeding mechanism 2 through moving, so that the feeding mechanism 2 can clamp the sheet material 101 from the coil and finally can facilitate cutting after the sheet material 101 is unfolded.

It will be appreciated that by wrapping the sheet 101 extending from the web 100 around the pull roller group 3-2, the sheet 101 can be automatically pulled from the web 100 when the pull roller group 3-2 is activated to operate, thereby achieving automatic web stretching.

In one embodiment, the pulling roll group 3-2 comprises a first pulling roll 3-21 and a second pulling roll 3-22, and the second pulling roll 3-22 and the first pulling roll 3-21 are close to each other through an outer wall, so that the second pulling roll 3-22 and the first pulling roll 3-21 can jointly roll and clamp the sheet 101 extending from the coil.

It can be understood that, since the sheet 101 is held between the first pulling rolls 3 to 21 and the second pulling rolls 3 to 22, when the first pulling rolls 3 to 21 and the second pulling rolls 3 to 22 roll together in opposite directions to each other (in the present embodiment, the first pulling rolls 3 to 21 rotate clockwise and the second pulling rolls 3 to 22 rotate counterclockwise), the sheet 101 can be pulled out by the first pulling rolls 3 to 21 and the second pulling rolls 3 to 22 together under the pressing force, so that the sheet 101 in the roll 100 can be pulled out automatically, and the pulled sheet 101 can be sent to the moving platform 3 to 1 automatically, and the transfer efficiency is more stable and efficient.

In one embodiment, the pulling roll set 3-2 further comprises a third pulling roll 3-23, the third pulling roll 3-23 is used for overlapping the sheet material 101 extending from the coiled material, the sheet material 101 is wound on the top of the third pulling roll 3-23, and the third pulling roll 3-23 can move up and down and is arranged between the first pulling roll 3-21 and the feeding frame 1.

It can be understood that the upward movement of the third pulling rollers 3 to 23 between the first pulling rollers 3 to 21 and the loading frame 1 can contribute to the increase of the tension of the sheet 101 during the transfer, so that the stable transfer of the sheet 101 can be ensured.

In one embodiment, the mobile platform 3-1 is respectively connected with a lifting mechanism and a transverse moving mechanism in a transmission manner, the lifting mechanism can drive the mobile platform 3-1 to move up and down, and the transverse moving mechanism can drive the mobile platform 3-1 to move transversely.

It can be understood that, in the operation process, when the moving platform 3-1 needs to send the sheet material 101 to the feeding mechanism 2 again after completing one cutting, the lifting mechanism may first drive the moving platform 3-1 to ascend (so as to avoid collision with the fixed platform 4-1 during the translation process), and then the traversing mechanism may drive the moving platform 3-1 to move forward to the feeding mechanism 2, so that the sheet material 101 laid on the surface of the moving platform 3-1 may be smoothly sent to the feeding mechanism 2, so as to realize the next unfolding of the sheet material by the feeding mechanism 2.

In one embodiment, the feeding mechanism 2 includes a movable frame 2-1 and a movable jaw 2-2, the movable jaw 2-2 is mounted on the movable frame 2-1 and can move transversely with the movable frame 2-1, and the movable jaw 2-2 is used for clamping the sheet 101 from the roll.

It can be understood that, in operation, the moving platform 3-1 moves the sheet 101 into the movable chuck 2-2 by moving forward, then the movable chuck 2-2 is closed gradually until the movable chuck 2-2 grips the sheet 101, and at the same time, the moving platform 3-1 is reset quickly and retreats away from the movable chuck 2-2, while the sheet 101 remains in the movable chuck 2-2, and after the movable chuck 2-2 increases the gripping force of the sheet 101, the movable chuck 2-2 moves forward along with the movable frame 2-1 to drive the sheet 101 to stretch and unfold from the roll 100.

In one embodiment, the friction force of the moving platform 3-1 to the sheet 101 is smaller than the friction force of the movable chuck 2-2 to the sheet 101, so that the sheet 101 can still stay in the movable chuck 2-2 after the moving platform 3-1 is withdrawn from the movable chuck 2-2.

Specifically, the movable chuck 2-2 comprises a first cylinder 2-21 and a base 2-22, the first cylinder 2-21 is vertically arranged on the movable frame 2-1, a movable rod of the first cylinder 2-21 can extend up and down, the base 2-22 is fixed at the bottom of the movable frame 2-1, the base 2-22 and the movable rod of the first cylinder 2-21 correspond to each other and are separated by a distance to form a clamping space, when in use, the sheet material 101 can move horizontally along with the movable platform 3-1 into the clamping space, then the first cylinder 2-21 is started, the movable rod of the first cylinder 2-21 is extended downwards, and the sheet material 101 can be clamped between the movable rod of the first cylinder 2-21 and the base 2-22.

It can be understood that, in the process of the sheet material 101 being pushed forward by the feeding mechanism 2 to be unfolded, the coil material 100 will roll along with the sheet material, when cutting is required, the feeding mechanism 2 will stop moving, at this time, the coil material 100 will roll continuously for a certain angle due to inertia, so that the sheet material 101 will continue to extend out, the unfolded sheet material 101 will not be flat or the size after each cutting will not be consistent, and the cutting will result in the problem of uneven cutting. Therefore, after the movable pressing piece 5 is additionally arranged, when the material mechanism 2 needs to stop moving, the movable pressing piece 5 can be used for pressing the sheet material 101 on the moving platform 3-1 downwards in advance, the rear sheet material 101 is prevented from continuously extending forwards due to the inertial rotation of the coiled material 100, the sheet material 101 between the feeding mechanism 2 and the movable pressing piece 5 can be kept flat, and the flatness of the sheet material 101 after being cut can be ensured to be consistent with the size after being cut every time.
