Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figure 1 - Figure 4 As shown, this utility model provides a technical solution for a PE adhesive protective film wrapping and unwrapping device, including a base 1, a rotating arm structure 2 inside the base 1, a reciprocating screw structure 3 on the rotating arm structure 2, a fixing rod 4 mounted on the top of the reciprocating screw structure 3, a limiting rod 5 at the top of the fixing rod 4, two winding rollers 6 between the limiting rod 5 and the fixing rod 4, two extrusion rollers 15 at the bottom of the limiting rod 5, and extrusion seats 13 on the outer side of each of the two extrusion rollers 15. The two extrusion seats 13 are respectively fixedly connected to the outer side of the two winding rollers 6, and the two extrusion rollers 15 are in contact with the two extrusion seats 13 respectively. A mounting plate 1 is rotatably connected to the outer side of each of the two extrusion rollers 15. 4. The top ends of the two mounting plates 14 are fixedly connected to the limiting rods 5. A connecting structure is provided between the two winding rollers 6 and the limiting rods 5. A circular tube 7 is provided between the two winding rollers 6. A support member is provided at the bottom of the circular tube 7. The support member includes two pillars 8. The two pillars 8 are fixedly connected to both sides of the bottom of the circular tube 7. The bottom ends of the two pillars 8 are fixedly connected to the fixing rods 4. Connecting rods 9 are slidably connected to both ends inside the circular tube 7. The two connecting rods 9 are fixedly connected to the two winding rollers 6 respectively. A return spring 10 is sleeved on the outside of the two connecting rods 9. The two ends of the two return springs 10 are fixedly connected to the two winding rollers 6 and the circular tube 7 respectively. A sliding structure is provided between the two winding rollers 6 and the fixing rods 4.

[0023] The sliding structure includes two convex grooves 11 and two convex blocks 12. The two convex grooves 11 are opened on both sides of the top of the fixed rod 4. The two convex blocks 12 are respectively disposed inside the two convex grooves 11 and slidably connected to the fixed rod 4. The two convex blocks 12 are respectively fixedly connected to the bottom ends of the two winding rollers 6.

[0024] Specifically, the connection structure will be further explained later. This allows the limiting rod 5 and the two winding rollers 6 to be separated. Then, the limiting rod 5 is lifted, and the limiting rod 5 drives the two extrusion rollers 15 to move upward through the two mounting plates 14. The two extrusion rollers 15 move away from the two extrusion seats 13 respectively. At this time, the two return springs 10 elastically return to their original positions, and one end of the two connecting rods 9 slides into the round tube 7.

The top end of the worm 22 passes through the top end of the mounting groove 19 and is rotatably connected to the limiting rod 5. A handle is installed on the top end of the worm 22.

[0027] Specifically, when the throttle is turned in the opposite direction, the worm 22 meshes with the worm wheel 21, and the worm wheel 21 drives the bidirectional screw 20 to rotate. The bidirectional screw 20 is threadedly connected to two moving blocks 23. Both moving blocks 23 slide in opposite directions inside the mounting groove 19. The two moving blocks 23 respectively drive the two protruding rods 24 to move away from the two connecting blocks 16. After the two protruding rods 24 release the limit on the two connecting blocks 16, the personnel can lift the limit rod 5 upwards to remove it, which is convenient for personnel to operate.
