Detailed Implementation

[0022] To make the above-mentioned features and advantages of this utility model more easily understood, specific embodiments are described below in conjunction with the accompanying drawings, but this utility model is not limited thereto.

[0023] refer to Figures 1 to 4

[0024] A PE film winding structure includes a frame, on which an inlet roller 10 for feeding the film is provided. At least one set of cutter mechanisms 20 adjustable along the axial direction of the inlet roller is provided on the front side of the inlet roller. A reversing roller 30 is provided on the lower side of the inlet roller. A winding mechanism 40 with adjustable spacing and adjustable along the axial direction of the inlet roller is provided in front of the reversing roller. The winding mechanism is equipped with a connector 60 for connecting two rolls. A tensioning mechanism 50 is provided between the winding mechanism and the reversing roller.

[0025] In this embodiment, the cutting mechanism includes a first slide 21 whose upper end face is slidably connected to the frame via a first guide rail 25 fixed on the frame. A swing plate 22 is hinged to the side of the first slide. A blade 23 facing the guide roller is provided at the lower end of the swing plate. A first driving mechanism for driving the swing plate to approach the guide roller is also provided on the first slide.

[0026] In this embodiment, the first driving mechanism includes an inclined cylinder 24 whose upper end is hinged to the front end of the first slide block, and the telescopic rod of the inclined cylinder is hinged to the lower part of the swing plate.

[0027] In this embodiment, the tensioning mechanism includes a pair of second slide blocks 51 that are slidably connected to the frame via second guide rails 57 fixed on the frame. Each of the second slide blocks has a fixed plate 52 with its lower end rotatably connected to it on its side. A tensioning roller 53 is rotatably connected between the upper ends of the two fixed plates. Each of the second slide blocks is provided with a second driving mechanism that drives the fixed plate to swing back and forth.

[0028] In this embodiment, the second drive motor includes a mounting plate 54 mounted on the upper end of the second slide block. A horizontal cylinder 55 with a telescopic rod facing forward is hinged to the mounting plate. The telescopic rod of the horizontal cylinder is hinged to the fixed plate.

[0029] In this embodiment, the lower part of the second slide is screwed with a hand-tightening bolt to lock the second slide to the frame.

[0030] In this embodiment, the winding mechanism includes a fixed platform 41 located on the front side of the frame, a pair of third guide rails 47 fixed on the platform, a pair of movable seats 42 whose lower ends are slidably connected to the third guide rails on the platform, a rotating seat 43 driven by a motor and used to install the roll on the upper inner side of the movable seat, and a third drive mechanism for driving the movement of the movable seat on the lower part.

[0031] In this embodiment, the third driving mechanism includes a rack 44 fixed to the lower front end of the table and parallel to the axial direction of the guide roller. A stepper motor 45 is fixed to the lower front end of the moving seat, and a drive gear 46 that meshes with the rack is installed at the output end of the stepper motor.

[0032] In this embodiment, both sides of the connector are provided with end heads 61 for extending into the drum, and the middle part of the connector is provided with an annular flange 62 for separating the two drums.

[0033] In this embodiment, the connector is made of metal.

[0034] Pre-adjust the distance between the two moving seats according to requirements. Then, according to the specifications of the PE film rolls, connect the two rolls using connectors, place them between the two moving seats, and adjust the distance between the two moving seats so that the rotating seats extend into both ends of the connected rolls and clamp them. Adjust the position of the cutting mechanism according to the specifications of the PE film rolls. If the overall width of the PE film is greater than the sum of the widths of the two rolls of PE film, a set of cutting mechanisms can be installed on each side of the PE film to cut the side edges. The cut side edge material is recycled through the waste recycling mechanism. If the width of the PE film is exactly the sum of the widths of the two rolls of PE film, only one cutting mechanism is needed, and the position of the cutting mechanism should be adjusted. The PE film is fed from back to front into the rear guide roller, and after passing over the upper side of the guide roller, it is conveyed towards the reversing roller. When the PE film reaches the front side of the guide roller, it is cut into two parts by the cutting mechanism and simultaneously passes over the rear side and bottom of the reversing roller, and then is fed into the winding mechanism through the tensioning mechanism. When the winding mechanism first starts working, the tension roller is close to the reversing roller to ensure tension. As the diameter of the PE film roll gradually increases, the horizontal cylinder pushes the fixed plate to swing the tension roller toward the winding mechanism to reduce tension. In another embodiment, the horizontal cylinder can be replaced by a horizontal electric cylinder.

[0035] If the terms "first" and "second" are used in the above description to define the components, those skilled in the art should know that the use of "first" and "second" is only for the convenience of distinguishing the components in the description. Unless otherwise stated, the above terms have no special meaning.

[0036] If this utility model discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, a fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws) or a non-detachable fixed connection (e.g., riveting or welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured using a casting process) (except where it is obviously impossible to use an integral forming process).
