[0028] Example 1: Please refer to Figure 1-7 , a stretch film winding and slitting device that is convenient for limiting, comprising a frame 1, a fixed seat 2 is fixedly connected to the front end of the frame 1, a reeling shaft 3 is movably connected to the left side of the frame 1, a first reeling shaft 4 is movably connected to the right side of the frame 1, a second reeling shaft 5 is movably connected below the first reeling shaft 4, a control seat 6 is installed on the right side of the fixed seat 2, a first roller 7 is movably connected to the inside of the frame 1, two sets of second rollers 8 are movably connected to the right side of the first roller 7, and an adjustable limiting mechanism is provided on the outside of the reeling shaft 3;
[0029] See also Figure 1-7 A stretch film winding and slitting device that is convenient for limiting also includes an adjustable limiting mechanism including a first servo motor 9. The adjustable limiting mechanism includes the first servo motor 9. The first servo motor 9 is installed on the rear side of the fixed seat 2. A bidirectional screw rod 10 is movably connected to the lower part of the frame 1. Two groups of first movable blocks 11 are sleeved on the outer side of the bidirectional screw rod 10. The top of the first movable block 11 is fixedly connected to a support column 12, and the top of the support column 12 is fixedly connected to a clamping arm 13.
[0030] The output end of the first servo motor 9 is connected to the bidirectional screw 10, and the control base 6 is electrically connected to the first servo motor 9. The two sets of bidirectional screws 10 are symmetrically arranged and can slide back and forth on the outside of the first servo motor 9. The length of the inner dimension of the clamping arm 13 is greater than the diameter of the unwinding shaft 3. The intersection of the two sets of second rollers 8 is at the same height as the top of the first roller 7. The tension of the first reel 4 and the second reel 5 is greater than that of the unwinding shaft 3.
[0031] Specifically, if Figure 1 、 Figure 2 ,and Figure 4 As shown, when in use, due to the different unwinding and rewinding tensions of the rolls at both ends of the stretch film, the thickness of the stretch film itself also has a certain deviation, and the unwinding shaft 3 is easily offset when rotating. By installing the first servo motor 9, the rotation of the first servo motor 9 drives the rotation of the bidirectional screw rod 10, thereby realizing the two groups of first movable blocks 11 sliding back and forth on the bidirectional screw rod 10, and adjusting the distance between the two groups of first movable blocks by the control seat 6, so that the clamping arm 13 can effectively limit the offset of the unwinding shaft 3, thereby reducing material waste caused by the offset of the unwinding shaft 3.
[0032] Embodiment 2: A second servo motor 14 is installed at the rear end of the fixed seat 2, a first movable shaft 15 is movably connected to the middle of the frame 1, a limit shaft 16 is sleeved on the outer side of the first movable shaft 15, a storage cylinder 17 is fixedly connected to the front and rear ends of the limit shaft 16, four sets of second movable blocks 18 are sleeved on the outer side of the limit shaft 16, a blade 19 is installed on the outer side of the second movable block 18, a rangefinder 20 is installed on the left side of the second movable block 18, a receiving plate 21 is installed on the right side of the second movable block 18, and a display screen 22 is installed inside the control seat 6. The second servo motor 14 is electrically connected to the control base 6. The output end of the second servo motor 14 is connected to the first movable shaft 15. The outer shape of the limit shaft 16 matches the inner shape of the second movable block 18. A damper is provided between the second movable block 18 and the limit shaft 16. The second movable block 18 and the limit shaft 16 can be fixed by bolts. The second movable block 18 can slide back and forth outside the limit shaft 16. The rangefinder 20, the receiving plate 21, and the display screen 22 are electrically connected. The four sets of second movable blocks 18 can slide to the outside of the storage tube 17.
[0033] Specifically, if Figure 1 、 Figure 2 、 Figure 6 and Figure 7 As shown, when in use, due to the different size requirements of the winding mill for slitting, the commonly used device is not convenient for quickly and accurately adjusting the distance between the blades 19. By matching the outer shape of the limit shaft 16 with the internal shape of the second movable block 18, the second movable block 18 can only slide back and forth on the outside of the limit shaft 16. By setting the rangefinder 20, the receiving plate 21 and the display screen 22, the distance between the two groups of blades 19 can be intuitively understood. After the second movable block 18 is moved to the appropriate position, it can be fixed to the limit shaft 16 by bolts, and then stretch films of different sizes can be cut out. At the same time, the four groups of second movable blocks 18 can slide to the outside of the storage tube 17, thereby completing the storage of the non-working blades 19.
[0034] Example 3: An electric cylinder 23 is installed at the top of the frame 1. The output end of the electric cylinder 23 is fixedly connected to a fixing frame 24. A second movable shaft 25 is movably connected to the inside of the fixing frame 24. A tension cylinder 26 is sleeved on the outside of the second movable shaft 25. The electric cylinder 23 is electrically connected to the control base 6. The fixing frame 24 can move up and down under the action of the electric cylinder 23.
[0035] Specifically, if Figure 1 and Figure 5 As shown, when in use, if the winding tension is insufficient during the unwinding and winding process, the stretch film may be wrinkled. By installing an electric cylinder 23 at the top of the frame 1, a fixing frame 24 is installed at the bottom of the electric cylinder 23, and a tension cylinder 26 is movably connected inside the fixing frame 24, the stretch film is pressed down, thereby maintaining tension in the stretch film during the winding process.
[0036] Working principle: When the present invention is in use, firstly, due to the different unwinding and rewinding tensions of the rolls at both ends of the stretch film, the thickness of the stretch film itself also has a certain deviation, and the unwinding shaft 3 is prone to deviation when rotating. By installing the first servo motor 9, the rotation of the first servo motor 9 drives the rotation of the bidirectional screw 10, thereby realizing the two groups of first movable blocks 11 sliding back and forth on the bidirectional screw 10, and adjusting the distance between the two groups of first activities by the control seat 6, so that the clamping arm 13 can effectively limit the deviation of the unwinding shaft 3, thereby reducing the waste of material caused by the deviation of the unwinding shaft 3. Secondly, since the size requirements of the slitting rewinding mill are different, the commonly used device is not convenient for quickly and accurately adjusting the distance between the blades 19. The outer shape of the limit shaft 16 is matched with the internal shape of the second movable block 18, thereby realizing the second movable The movable block 18 can only slide back and forth on the outside of the limit shaft 16. By setting the rangefinder 20, the receiving plate 21 and the display screen 22, the distance between the two sets of blades 19 can be intuitively understood. After the second movable block 18 moves to the appropriate position, it can be fixed to the limit shaft 16 by bolts, and then the stretch film of different sizes can be cut out. At the same time, the four groups of second movable blocks 18 can slide to the outside of the storage tube 17, and then the storage of the non-working blades 19 is completed. At the same time, during the unwinding and rewinding process, if the rewinding tension is insufficient, it may cause wrinkles in the stretch film. By installing an electric cylinder 23 at the top of the frame 1, a fixed frame 24 is installed at the bottom of the electric cylinder 23, and the internal movably connected to the tension cylinder 26, the stretch film can be pressed down, thereby keeping the tension of the stretch film during the rewinding process.
