Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

A first rotating shaft 10 is provided at one end of the unwinding roller 9, a second rotating shaft 11 is provided at the other end of the unwinding roller 9, a rotatably connected support plate 12 is provided on the outer sleeve of the second rotating shaft 11, the support plate 12 is fixedly connected to the unwinding frame 2, the first rotating shaft 10 and the second rotating shaft 11 are respectively connected to the unwinding roller 9 through mounting parts, two control boxes 13 are fixedly connected to the unwinding frame 2, a rotatably connected fixed frame 14 is provided on the outer sleeve of the first rotating shaft 10, and the fixed frame 14 is fixedly connected to the control box 13, a first damping disk 15 is fixedly connected to the first rotating shaft 10, and the control box 13 is close to the first damping disk 15 A second damping disc 18 is provided on one side of the first connecting shaft 16, and the second damping disc 18 passes through the first connecting shaft 16. A rotating sleeve 17 is sleeved on the outside of the first connecting shaft 16, and the rotating sleeve 17 is fixedly connected to the second damping disc 18. A rotating fixed sleeve 21 is sleeved on the outside of the rotating sleeve 17, and the fixed sleeve 21 is fixedly connected to the control box 13. One end of the first connecting shaft 16 is fixedly connected to the first damping disc 15, and the other end of the first connecting shaft 16 is sleeved on a rotating synchronous plate 19, and the synchronous plate 19 is located in the control box 13. The rotating sleeve 17 and the synchronous plate 19 are connected by a connecting plate 20. The control box 13 is provided with a rotary feeding unit matched with the rotary sleeve 17, and the control box 13 is provided with a relative rotation protection component matched with the first connecting shaft 16 and the synchronous plate 19 respectively; when the tension of the paper drawing material is not at the preset value, the lifting plate 5 is driven to move in the vertical direction through the damping tension adjustment structure, and the paper drawing material is pressed by the first tension roller 7 and the second tension roller 8 to make the tension of the paper drawing material at the preset value. When the distance measuring sensor 36 detects that the vertical movement distance of the lifting plate 5 exceeds the preset range, the first connecting shaft 16 is driven by the relative rotation protection component. As the synchronous plate 19 and the rotating sleeve 17 rotate, the first connecting shaft 16 drives the first damping disk 15 to rotate relative to the second damping disk 18, thereby causing the unwinding roller 9 to rotate relative to the rotating sleeve 17, thereby changing the length of the paper drawing material between the unwinding roller 9 and the tension box 4, so that the tension of the paper drawing material is at a preset value.

Embodiment 2, based on embodiment 1, as shown in Figures 2 and 3, the damping tension adjustment structure includes two third rotating shafts 22 arranged below the lifting plate 5, the outer sleeve of the third rotating shaft 22 is provided with a first supporting portion 23 that is rotatably connected, and the first supporting portion 23 is fixedly connected to the inner wall of the tension box 4, the lifting plate 5 and the tension box 4 are connected by a guide member, a support plate 24 is fixedly connected to the third rotating shaft 22, and the support plate 24 is in contact with the bottom of the lifting plate 5, and second connecting shafts 25 are respectively provided at both ends of the third rotating shaft 22, and the outer sleeve of the second connecting shaft 25 is provided with a second supporting portion 26 that is rotatably connected, and the second supporting portion 26 is fixedly connected to the inner wall of the tension box 4, the second connecting shaft 25 and the third rotating shaft 22 are connected by a damping member, and a driver that matches the second connecting shaft 25 is provided in the tension box 4, and the damping member includes a third damping disk 27 fixedly mounted on the second connecting shaft 25, and two ends of the third rotating shaft 22 The ends are respectively fixedly connected with fourth damping discs 28, and the third damping disc 27 and the fourth damping disc 28 are in contact, the driver includes a first bevel gear 31 fixedly mounted on the second connecting shaft 25, two first motors 29 are fixedly connected in the tension box 4, the output end of the first motor 29 is fixedly connected with a transmission shaft 30, and the four second connecting shafts 25 are located between the two transmission shafts 30, the outer fixed sleeve of the transmission shaft 30 is provided with two second bevel gears 32, and the two adjacent second bevel gears 32 are respectively meshed with the corresponding two first bevel gears 31, and the end of the transmission shaft 30 away from the first motor 29 is sleeved with a third support portion 33 rotatably connected, the third support portion 33 is fixedly connected to the inner wall of the tension box 4, the guide member includes a plurality of guide columns 34 fixedly mounted on the inner wall of the bottom of the tension box 4, the outer sleeve of the guide column 34 is provided with a guide sleeve 35, and the top of the guide sleeve 35 is fixedly connected to the bottom of the lifting plate 5;

The guide column 34 and the guide sleeve 35 are designed to enable the lifting plate 5 to move smoothly in the vertical direction. The transmission shaft 30 is driven to rotate by the first motor 29, and the transmission shaft 30 drives the second bevel gear 32 to rotate. The second bevel gear 32 drives the second connecting shaft 25 and the third damping disk 27 to rotate through the first bevel gear 31. The third damping disk 27 drives the fourth damping disk 28 and the third rotating shaft 22 to rotate by friction. The third rotating shaft 22 drives the support plate 24 to rotate. The support plate 24 pushes the lifting plate 5 and the first tension roller 7 to move upward. The first tension roller 7 and the second tension roller 8 press the paper drawing material. When the tension of the paper drawing material reaches the preset value, as the transmission shaft 30 continues to rotate, the fourth damping disk 28 and the third rotating shaft 22 stop rotating. The third damping disk 27 cannot drive the fourth damping disk 28 and the third rotating shaft 22 to rotate by friction. As the paper drawing material is conveyed, when the paper drawing material is drawn, When the tension of the paper material is greater than a preset value, the pressure applied by the paper material to the first tension roller 7 is greater than the preset value. At this time, the paper material drives the first tension roller 7 and the lifting plate 5 to move downward, and the lifting plate 5 drives the third rotating shaft 22 to rotate in the opposite direction through the supporting plate 24, and the tension of the paper material becomes smaller. When the tension of the paper material is reduced to the preset value, the lifting plate 5 and the first tension roller 7 stop moving downward. Conversely, when the tension of the paper material is less than the preset value, the pressure applied by the paper material to the first tension roller 7 is less than the preset value. At this time, the third damping disk 27 drives the fourth damping disk 28 to rotate synchronously through friction force, and the third rotating shaft 22 drives the lifting plate 5 and the first tension roller 7 to move continuously upward through the supporting plate 24. When the tension of the paper material rises to the preset value, the lifting plate 5 and the first tension roller 7 stop moving upward. As the transmission shaft 30 continues to rotate, the third damping disk 27 cannot drive the third rotating shaft 22 to rotate through friction force.

Embodiment 3, based on Embodiment 1, as shown in FIG. 2 and FIG. 5, the locking support member includes a plurality of screw rods 37 fixedly mounted on the top of the support seat 6, the top of the screw rod 37 passes through the tension box 4, and the outer sleeve of the screw rod 37 is provided with two nuts 38, and the two adjacent nuts 38 are respectively in contact with the inner wall and the outer wall of the tension box 4, and the rotary feeding unit includes a gear ring 39 fixedly sleeved on the outside of the rotating sleeve 17, and the gear ring 39 is located in the control box 13, and the control box 13 is fixedly connected with a second motor 40, and the output end of the second motor 40 is fixedly connected with a first gear 41 meshing with the gear ring 39;

The support seat 6 is fixed relative to the tension box 4 through the cooperation of the screw rod 37 and the nut 38. When one end of the paper material needs to pass through the first tension roller 7 and the second tension roller 8, the staff drives the two adjacent nuts 38 to rotate so that the two adjacent nuts 38 no longer clamp the tension box 4, thereby releasing the limitation on the position of the support seat 6. The staff drives the support seat 6 and the screw rod 37 to move upward relative to the tension box 4, increasing the distance between the second tension roller 8 and the first tension roller 7, so as to facilitate passing one end of the paper material from the first tension roller 7 and the second tension roller 8. The first gear 41 is driven to rotate by the second motor 40, and the first gear 41 drives the rotating sleeve 17 to rotate through the gear ring 39.

The relative rotation protection assembly drives the first connecting shaft 16 to rotate relative to the synchronous plate 19 and the rotating sleeve 17, so that the first damping disk 15 drives the unwinding roller 9 to rotate relative to the rotating sleeve 17 through the first connecting shaft 16, thereby changing the length of the paper material drawn between the unwinding roller 9 and the tension box 4. The damping tension adjustment structure can drive the lifting plate 5 to move to a preset height range. When the unwinding roller 9 needs to be replaced, the staff drives the bolt 57 to rotate so that the bolt 57 is disengaged from the first mounting disk 55 and the second mounting disk 56, and the fixed relationship between the unwinding roller 9 and the first rotating shaft 10 and the second rotating shaft 11 is released.

The third damping disk 27 drives the fourth damping disk 28 and the third rotating shaft 22 to rotate by friction. The third rotating shaft 22 drives the support plate 24 to rotate. The support plate 24 pushes the lifting plate 5 and the first tension roller 7 to move upward. The first tension roller 7 and the second tension roller 8 press the paper drawing material. When the tension of the paper drawing material reaches the preset value, as the transmission shaft 30 continues to rotate, the fourth damping disk 28 and the third rotating shaft 22 stop rotating. The third damping disk 27 cannot drive the fourth damping disk 28 and the third rotating shaft 22 to rotate by friction. As the paper drawing material is conveyed, when the paper drawing material is drawn, When the tension of the paper material is greater than a preset value, the pressure applied by the paper material to the first tension roller 7 is greater than the preset value. At this time, the paper material drives the first tension roller 7 and the lifting plate 5 to move downward, and the lifting plate 5 drives the third rotating shaft 22 to rotate in the opposite direction through the supporting plate 24, and the tension of the paper material becomes smaller. When the tension of the paper material is reduced to the preset value, the lifting plate 5 and the first tension roller 7 stop moving downward. Conversely, when the tension of the paper material is less than the preset value, the pressure applied by the paper material to the first tension roller 7 is less than the preset value. At this time, the third damping disk 27 drives the fourth damping disk 28 to rotate synchronously through the friction force, and the third rotating shaft 22 drives the lifting plate 5 and the first tension roller 7 to move upward continuously through the supporting plate 24. When the tension of the paper material rises to the preset value, the lifting plate 5 and the first tension roller 7 stop moving upward. With the continuous rotation of the transmission shaft 30, the third damping disk 27 cannot drive the third rotating shaft 22 to rotate through the friction force.

The support seat 6 is fixed relative to the tension box 4 through the cooperation of the screw rod 37 and the nut 38. When one end of the paper drawing material needs to pass through the first tension roller 7 and the second tension roller 8, the staff drives the two adjacent nuts 38 to rotate so that the two adjacent nuts 38 no longer clamp the tension box 4, thereby releasing the limitation on the position of the support seat 6. The staff drives the support seat 6 and the screw rod 37 to move upward relative to the tension box 4, increasing the distance between the second tension roller 8 and the first tension roller 7, so as to facilitate passing one end of the paper drawing material between the first tension roller 7 and the second tension roller 8. The first gear 41 is driven to rotate by the second motor 40, and the first gear 41 drives the rotating sleeve 17 to rotate through the gear ring 39. The second damping disk 18 drives the first damping disk 15, the first rotating shaft 10 and the unwinding roller 9 to rotate through the friction force, so that the paper drawing material can be fed.

When the rotating sleeve 17 and the synchronous plate 19 rotate, the synchronous plate 19 drives the guide bar 49 and the tooth plate 47 to rotate through the fixed plate 43 and the fixed block 48, and the tooth plate 47 drives the movable shaft 51 to rotate coaxially with the rotating sleeve 17 through the connecting frame 52. When the distance measuring sensor 36 detects that the vertical movement distance of the lifting plate 5 exceeds the preset range, the hydraulic telescopic rod 54 drives the movable plate 53 and the movable shaft 51 to move horizontally, and the movable shaft 51 drives the tooth plate 47 to slide relative to the fixed block 48 through the connecting frame 52, and the guide bar 49 slides relative to the guide groove 50. The tooth plate 47 can drive the third connecting shaft 44 and the fourth bevel gear 45 to rotate through the second gear 46, and the fourth bevel gear 45 drives the first connecting shaft 16 and the first damping plate 15 to rotate relative to the second damping plate 18 through the third bevel gear 42. The relative rotation protection component drives the first connecting shaft 16 to rotate relative to the synchronous plate 19 and the rotating sleeve 17, so that the first damping disk 15 drives the unwinding roller 9 to rotate relative to the rotating sleeve 17 through the first connecting shaft 16, thereby changing the length of the paper material drawn between the unwinding roller 9 and the tension box 4. The damping tension adjustment structure can drive the lifting plate 5 to move to a preset height range. When the unwinding roller 9 needs to be replaced, the staff drives the bolt 57 to rotate so that the bolt 57 is disengaged from the first mounting disk 55 and the second mounting disk 56, and the fixed relationship between the unwinding roller 9 and the first rotating shaft 10 and the second rotating shaft 11 is released. The staff drives the unwinding roller 9 to move horizontally so that the unwinding roller 9 is no longer located between the first rotating shaft 10 and the second rotating shaft 11, and the unwinding roller 9 can be removed, which is convenient for replacing the unwinding roller 9.
