[0030] Example 2:

[0031] On the basis of the first embodiment, in this embodiment, by installing a rolling roller 32 and a supporting roller 31, the passing PET packaging paper 1 can be rolled and stretched to prevent the PET packaging paper 1 from wrinkling during the winding process. By rotating the worm 38 forward, the worm 38 can drive the rolling roller 32 to move upward through the transmission worm gear 39, the externally threaded vertical rod 34, the support seat 33 and the upper extension shaft 36. At this time, the distance between the rolling roller 32 and the supporting roller 31 will gradually increase, and conversely, the distance between the rolling roller 32 and the supporting roller 31 can gradually decrease, so that the staff can match and adjust the distance between the rolling roller 32 and the supporting roller 31 according to the thickness of the PET packaging paper 1.

[0032] The guide assembly 3 includes a supporting roller 31, a rolling roller 32, a support seat 33, an upper extension shaft 36 and a lower extension shaft 37. The support seats 33 are symmetrically installed on the left and right sides of the concave support seat 2. The support seat 33 can support the upper extension shaft 36. The rolling roller 32 is installed on the upper side of the concave support seat 2. The specifications of the rolling roller 32 and the supporting roller 31 are the same. The left and right lengths of the rolling roller 32 are greater than the left and right widths of the PET packaging paper 1. The supporting roller 31 is installed below the rolling roller 32. The supporting rollers 31 and the rolling rollers 32 of the same specifications can press the PET packaging paper passing through. The paper 1 is guided, rolled and stretched to prevent the PET packaging paper 1 from wrinkling during the process of being rolled on the annular side of the winding drum 54. The upper extension shaft 36 is symmetrically installed on the left and right end surfaces of the rolling roller 32. The upper extension shaft 36 enables the rolling roller 32 to be rotatable.

[0033] The support seat 33 is provided with an externally threaded vertical rod 34, which is connected to the transmission worm gear 39 by welding. A vertical internally threaded through hole is provided inside the support seat 33, and the vertical internally threaded through hole is engaged with the externally threaded vertical rod 34. The vertical internally threaded through hole enables the externally threaded vertical rod 34 rotating forward or reversely to drive the support seat 33 to move up and down. A transmission worm gear 39 is provided on the lower side of the annular side of the externally threaded vertical rod 34, and a worm 38 is engaged on the rear side of the annular side of the transmission worm gear 39. The worm 38 is connected to the follower ring 381 and the turntable 382 by welding. The worm 38 can drive the transmission worm gear 39 to rotate, so that the transmission worm gear 39 drives the externally threaded vertical rod 34 to rotate, and the meshing worm 38 and the transmission worm gear 39 also have self-locking ability to prevent the support seat from being locked. In case 33 falls back during use, limiting grooves 35 are symmetrically provided on the left and right sides of the inner wall of the concave support seat 2, and the limiting grooves 35 match the support seat 33. The limiting grooves 35 can limit the support seat 33 to prevent the support seat 33 from deflecting or shaking during the lifting process. A turntable 382 is provided at the right end of the worm 38, and the turntable 382 is convenient for the staff to rotate the worm 38 by hand. A locking screw 383 is installed on the upper side of the turntable 382, ​​and the locking screw 383 can lock the turntable 382. A follower ring 381 is provided on the right side of the annular side surface of the worm 38, and an annular block cover 21 is installed on the lower side of the right end surface of the concave support seat 2. The follower ring 381 and the annular block cover 21 prevent the worm 38 from being displaced or shaking during rotation.

[0034] Working principle: The staff first rotates the worm 38 forward through the turntable 382, ​​so that the worm 38 drives the externally threaded vertical rods 34 on the left and right sides to reverse together through the transmission worm gear 39, and the reversed externally threaded vertical rods 34 will drive the support seats 33 on the left and right sides to move upward synchronously through the vertical internally threaded through-holes, and then the support seats 33 drive the rolling roller 32 to move upward together through the upper extension shaft 36. At this time, the distance between the rolling roller 32 and the supporting roller 31 will gradually increase. Similarly, when the worm 38 is reversed, the distance between the rolling roller 32 and the supporting roller 31 will gradually decrease, so that the staff can match and adjust the distance between the rolling roller 32 and the supporting roller 31 according to the thickness of the PET packaging paper 1. After the adjustment is completed, tighten the locking screw 383 with the help of an external wrench. , to prevent the turntable 382 from rotating again; then loosen the fixing screw 561 with the help of an external wrench, and the second positioning block 55 can be moved left and right at this time, so that the staff can adjust the distance between the first positioning block 53 and the second positioning block 55 according to the left and right width of the PET packaging paper 1. After the adjustment is completed, tighten the fixing screw 561 again to prevent the second positioning block 55 from loosening and displacement during use; then the staff can pass one end of the PET packaging paper 1 to be rolled up between the rolling roller 32 and the supporting roller 31 and wrap it around and adhere it to the annular side surface of the winding drum 54. At this time, the low-speed motor 51 is started again, so that the low-speed motor 51 drives the winding drum 54 to rotate at a low speed through the connecting shaft 52 and the extension rod 57 (the direction of rotation of the winding drum 54 is in the direction of rotation). Figure 2 54 is drawn in the figure), so that the winding drum 54 rotating at a low speed can wind up the PET wrapping paper 1. During this process, the first positioning block 53 and the second positioning block 55 will block and position the PET wrapping paper 1 during the winding process to prevent the PET wrapping paper 1 from deflecting when being wound on the annular side surface of the winding drum 54. The supporting roller 31 and the rolling roller 32 will roll and stretch the passing PET wrapping paper 1 to prevent the PET wrapping paper 1 from wrinkling during the winding process, thereby ensuring the winding quality of the PET wrapping paper 1. When the PET wrapping paper 1 is wound up, the staff first turns off the low-speed motor 51, then uses an external wrench to loosen the mounting screw 581 and pull and remove the blocking sleeve 58. At this time, the winding drum 54 can be removed from the outer surface of the extension rod 57 to transfer the wound PET wrapping paper 1.
