[0023] Embodiments
[0024] As Figures 1 to 3The utility model provides a kind of winding equipment for PE wrapping film processing, including winding machine 1 and PE winding roll 4, winding frame 11 is rotatably connected in winding machine 1, a pair of limit block 15 that winding frame 11 rotates is fixedly connected in the inside of winding machine 1, limit block 15 is to ensure that winding frame 11 rotates to resist limit block 15, after can make that clamping block 13 and the PE winding roll 4 to be fixed correspond.
[0025] As shown in Figure 1 、 Figure 2 , the inside of winding frame 11 is equipped with clamping mechanism, and the clamping mechanism includes a pair of first air cylinder 12 fixedly connected on winding frame 11, and the piston rod of first air cylinder 12 is movably penetrated through winding frame 11 and then fixedly connected with clamping block 13, one end of clamping block 13 away from first air cylinder 12 is provided as a tapered end, and the tapered end is automatically close to the center position during insertion into the end hole of PE winding roll 4. Even if there is a certain deviation or inclination when the tapered end is initially inserted, as the insertion proceeds, the tapered surface will interact with the hole wall, generating a force that gradually aligns the tapered end with the center, thereby reducing the requirement for initial position accuracy.
[0026] In addition, as shown in Figure 2 、 Figure 3 , a material supporting mechanism is fixedly connected below the clamping mechanism in winding machine 1, and the material supporting mechanism includes a support block 2 fixedly connected on winding machine 1, and a pair of stable frames 25 are fixedly connected to the outer wall of support block 2, so that the support block 2 installed on the winding machine 1 is more solid and durable. The bottom end of stable frame 25 is fixedly connected with winding machine 1, a mounting groove 21 is formed in the middle of support block 2, a second air cylinder 22 is fixedly connected inside the mounting groove 21, a supporting plate 3 supporting PE winding roll 4 is fixedly connected to the piston rod of second air cylinder 22, a pair of sliding grooves 23 are formed in the top of support block 2, a pair of sliding rods 24 are fixedly connected to the bottom of supporting plate 3 and inserted into the sliding grooves 23, and the sliding rods 24 slide inside the sliding grooves 23, so that the supporting plate 3 slides up and down only vertically.
[0027] It is worth mentioning that, as shown in Figure 3 , an arc-shaped groove 31 is formed in the top of supporting plate 3 to clamp PE winding roll 4, and the size of arc-shaped groove 31 corresponds to the size of PE winding roll 4, so that different sizes of arc-shaped grooves 31 need to be customized for different sizes of PE winding roll 4. A clamping plate 32 is fixedly connected at both ends inside the arc-shaped groove 31.
[0028] Further, as shown in Figure 1As shown, the material support mechanism is equipped with a positioning mechanism that raises the PE winding roll 4 into the clamping mechanism. The positioning mechanism includes a mounting hole 14 at one end of the clamping block 13. A laser lamp is installed inside the mounting hole 14. The laser beam emitted by the laser lamp has the characteristic of linear propagation and can provide a clear and accurate reference line. The operator can judge the relative position of the PE winding roll 4 and the clamping block 13 by whether the laser beam accurately enters the holes at both ends of the PE winding roll 4 and its position in the holes, thereby making precise adjustments to ensure that the two are coaxial and improve the accuracy and efficiency of alignment.
[0029] In this embodiment, when the processing of PE stretch film requires the use of a winding device, such as... Figure 1 As shown, the PE winding roll 4 is placed into the arc-shaped groove 31 at the top of the tray 3. A pair of retaining plates 32 inside the arc-shaped groove 31 hold the PE winding roll 4 in place, preventing it from extending beyond the ends of the groove. Next, the second cylinder 22 inside the mounting slot 21 is activated. The piston rod of the second cylinder 22 pushes the tray 3 upwards, and the tray 3 slides vertically along the sliding groove 23 via a pair of sliding rods 24 at its bottom. Then, the laser lamp inside the mounting hole 14 is turned on until the PE winding roll 4 moves upwards and is aligned with the center of the clamping block 13. This ensures the laser beam emitted by the laser lamp has a straight-line propagation characteristic, providing a clear and accurate reference line. The operator can determine the relative position of the PE winding roll 4 and the clamping block 13 by observing whether the laser beam accurately enters the holes at both ends of the PE winding roll 4 and its position within the holes, thus making precise adjustments to ensure coaxiality and improve alignment accuracy and efficiency. Finally, the first cylinder 12 on the take-up frame 11 is activated. The piston rod of the first cylinder 12 pushes the clamping blocks 13 into the holes at both ends of the PE winding roll 4, thereby allowing the take-up frame 11 to clamp and fix the PE winding roll 4, which is quick and easy to operate. The tapered end shape of the clamping block 13 causes it to automatically move towards the center position during insertion into the hole. Even if the tapered end has a certain offset or tilt during initial insertion, as insertion progresses, the tapered surface will interact with the hole wall, generating a force that gradually aligns the tapered end with the center, thereby reducing the requirement for initial positional accuracy.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
