[0015] Compared with the prior art, the present invention can fix material rollers of different widths by arranging a fixing component in the anti-wrinkle pressing device for producing waterproof and wear-resistant PE heat shrink film for packaging. The material roller applies a thrust to the limiting block through the limiting block, so that the limiting block drives the slider to move to one side in the inner cavity of the installation groove. Since a limiting spring is installed on one side of the slider, the limiting spring also applies an elastic rebound tension to the slider, so that the slider is limited to a suitable position.

[0017] The present invention can realize coating of the packaging by arranging a packaging wrinkle-proof film pressing device in the wrinkle-proof film pressing device for producing waterproof and wear-resistant PE heat shrink film for packaging, and respectively removes wrinkles on the side edges of the packaging through the lower pressing roller and the side pulling roller, and the lower pressing roller presses the heat shrink film downward to make the heat shrink film cover the surface of the packaging material, and at the same time, the lower pressing roller presses the heat shrink film to make the heat shrink film on one side of the packaging material be subjected to lateral film pressing to play an anti-wrinkle effect, and then the mounting bases on both sides rotate outward on the outer wall of the rotating shaft respectively, so that the mounting base drives the side pulling rollers to perform side film pressing on the heat shrink film through the limiting rod, so that the heat shrink film on the other side of the packaging material is subjected to lateral film pressing to play an anti-wrinkle effect, thereby solving the problem that when the heat shrink film covers the packaging product, the side edges of the packaging are not timely subjected to the anti-wrinkle film pressing treatment, which will cause wrinkles during packaging, thereby affecting the subsequent heat shrink film coating effect.

[0018] The present invention provides a packaging wrinkle-proof film pressing device for producing waterproof and wear-resistant PE heat shrink film for packaging, so that when the lower pressing plate drives the lower pressing bottom plate to a suitable position through the spring telescopic rod, the spring telescopic rod is compressed by force, thereby causing the circular cutting blade to move downward, and when the circular cutting blade contacts the heat shrink film, the circular cutting blade cuts the heat shrink film, and then the controller controls the hot air blower gun, which blows out hot air to heat-dry and coat the heat shrink film on the surface of the packaging material, and pulls out the fixed bracket to disconnect the magnetic connection between the fixed bracket and the magnetic base, and then fixes other types of tools on the outer wall of the fixed bracket, and then fixes the fixed bracket on the inner wall of the magnetic base by adsorbing it, so that the installation is relatively simple, thereby solving the problem that the operation steps of tool changing and film coating processing in the existing device are relatively complicated, time-consuming and labor-intensive.

A hot blow gun 709 is provided on the outer wall of the lower pressure bottom plate 708, and a rotating shaft 710 is symmetrically arranged on the opposite inner wall of the lower pressure bottom plate 708. A mounting base 711 is rotatably connected to the outer wall of the rotating shaft 710, wherein the mounting base 711 is provided with two groups and is respectively located on the outer wall of the rotating shaft 710, and one end of the mounting base 711 is installed with a side pulling roller 713 through a limiting rod 712. When the electric cylinder 705 is running, the electric cylinder 705 will drive the lower pressure plate 706 to move downward, so that the lower pressure plate 706 drives the lower pressure bottom plate through the spring telescopic rod 707 When the packaging material is covered with the heat shrink film 508, the packaging material 708 moves downward, thereby causing the bottom plate 708 to move downward through the rotating shaft 710 and driving the mounting base 711 to move downward. Since a side-pull roller 713 is installed on one side of the mounting base 711 through a limiting rod 712, when the side-pull roller 713 is in contact with the heat shrink film 508 on the surface of the packaging material, the side-pull roller 713 is subjected to a reaction force and moves to one side, causing the mounting bases 711 on both sides to rotate outward on the outer wall of the rotating shaft 710 respectively, thereby causing the mounting base 711 to drive the side-pull roller 713 to perform side pressing on the heat shrink film 508 through the limiting rod 712, so that the heat shrink film 508 on the other side of the packaging material is subjected to side pressing, thereby playing an anti-wrinkle role, thereby solving the problem that when the heat shrink film is used to cover the packaging product, the side of the packaging is not subjected to anti-wrinkle pressing treatment in time, which will cause wrinkles during packaging, thereby affecting the subsequent heat shrink film coating effect.

[0031] When the lower pressure plate 706 is driven to move downward by the electric cylinder 705, when the lower pressure plate 706 drives the lower pressure base plate 708 to a suitable position through the spring telescopic rod 707, the spring telescopic rod 707 will be compressed. When the spring telescopic rod 707 is compressed, the circular cutting blade 718 moves downward. When the circular cutting blade 718 contacts the heat shrink film 508, the circular cutting blade 718 cuts the heat shrink film 508. Then the controller 2 controls the hot air blower 709. The hot air blower 709 blows out hot air to heat and dry the heat shrink film 508 on the surface of the packaging material for coating. At the same time, the fixed block 715 is located between the tension springs 714, and one end of the fixed block 715 is installed A magnetic base 716 is provided, and a fixed bracket 717 is magnetically connected to the inner wall of the magnetic base 716, and a circular cutting blade 718 is installed on the outer wall of the fixed bracket 717, wherein the bottom of the circular cutting blade 718 is higher than the top of the side pulling roller 713. When the tool needs to be replaced, it is only necessary to pull out the fixed bracket 717 to disconnect the magnetic connection between the fixed bracket 717 and the magnetic base 716, and then fix other types of tools on the outer wall of the fixed bracket 717, and then fix the fixed bracket 717 on the inner wall of the magnetic base 716. The installation is relatively simple, thereby solving the problem that the operation steps of tool changing and laminating processing of the existing device are relatively complicated, time-consuming and labor-intensive.
