[0042] An induction reflector transmitter 27 is provided above the curling heating knife 5, and the induction reflector transmitter 27 is fixedly mounted on the supporting shell 9. An induction receiver 29 is provided below the induction reflector transmitter 27. The induction reflector transmitter 27 and the induction receiver 29 are respectively located on the upper and lower sides of the abutment between the plate and the heating knife. The induction receiver 29 is mounted on a translation frame 30, and the translation frame 30 moves horizontally to move closer to and away from the curling heating knife 5.

[0043] A hoist 31 is provided below the arc plate 4 , a cable is wound around the hoist 31 , and the other end of the cable is fixed to a side of the workbench 6 away from the hoist 31 . A wire rod 28 is provided on the arc plate 4 for the cable to pass through.

[0044] The bottoms of the fixed shell 7 and the supporting shell 9 are both mounted on a movable plate 33 via a column 32 , and the two movable plates 33 are slidably connected to the workbench 6 to move in a horizontal direction toward and away from each other.

[0045] In the above-mentioned specific technical scheme, when the sheet is rolled by the utility model, first, one end of the sheet is brought into contact with the side wall of the rolling heating knife 5. In order to ensure the accuracy of the sheet fixing, the sheet can be pushed close to the rolling heating knife 5 by the positioning rod 3, so that the entire end surface of one end of the sheet is in close contact with the rolling heating knife 5. After the positioning of one end of the sheet is completed, the pressing plate 8 moves downward to fix one end of the sheet, and then the positioning rod 3 is removed. The flap 1 is flipped upward under the action of the flip cylinder 15. At the same time, the cable wound on the winch 31 causes the other end of the sheet to bypass the fixed shell 7 and the supporting shell 9, and is moved to the bottom of the roller 11 under the guidance of the arc plate 4. The roller 11 rotates under the drive of the drive motor 13. , thereby driving the other end of the plate to move in the direction close to the curling heating knife 5, reducing the trouble of manual adjustment.

When the entire end surface of the end of the plate fits the side wall of the curling heating knife 5, the induction receiver 29 transmits an induction reflector, the curling heating knife 5 moves downward, and the two movable plates 33 move in the direction of approaching each other, so that the two end surfaces of the plate are spliced ​​together, thereby realizing the curling of the plate. By setting the induction reflector transmitter 27 and the induction receiver 29, it can be prevented that the end surfaces at both ends of the plate are spliced ​​in an inclined state.

[0046] It is worth mentioning that the inductive receiver 29 is installed on the movable frame, and the movable frame is controlled by the cylinder to move closer to and away from the curling heating knife 5. When the entire end surface of the end of the plate is tightly fitted with the side of the curling heating knife 5, the inductive receiver 29 sends out a signal, and the movable frame moves away from the curling heating knife 5, and then the curling heating knife 5 descends, so that the two movable plates 33 move closer to each other, and the movable frame drives the inductive receiver 29 to move away from the curling heating knife 5, mainly to prevent the position of the inductive receiver 29 from interfering with the downward movement of the curling heating knife 5.
