Description

Technical Field

[0001] The utility model relates to the technical field of PE film production equipment, in particular to a PE film wrinkle-proof pressing device. Background Art

[0002] PE heat shrink film is made of high-pressure polyethylene and appropriate auxiliary materials after one-time inflation. It is characterized by good toughness, high softness, good heat sealing, strong impact resistance, tear resistance, and not easy to break. PE heat shrink film is particularly suitable for packaging large-sized or irregular objects, solving the global problem of packaging special-shaped objects. Now this new packaging method no longer requires any inner packaging and wooden boxes, greatly reducing the packaging cost of enterprises, so it has been widely used. When producing PE heat shrink film, when the PE heat shrink film is wrinkled during the transmission process, it needs to be de-wrinkled to prevent affecting the subsequent winding quality of the heat shrink film. However, the existing anti-wrinkle device for PE heat shrink film production is relatively complex in structure, with high maintenance costs. When wrinkles appear, the de-wrinkling effect is not good, and the practicality is low.

[0003] For example, a wrinkle-proof film pressing device for PE heat shrink film production with announcement number CN209097832U includes a base, a lifting and lowering film pressing structure, a film collecting and rolling drum structure, an adjustable cleaning sponge structure, a side plate, a bottom plate, a hook, a storage box, a box opening, a buffer layer, an opening ring, a support rod, a mounting tube, a tension bolt and an anti-slip seat. The setting of the slide seat, the slide groove, the slider, the connecting shaft, the pressing wheel and the fixing bolt of the utility model is conducive to preventing the PE heat shrink film from wrinkling and improving the film pressing quality; the setting of the crank, the rotating shaft, the support seat, the bearing, the fixing bolt and the reel is conducive to collecting the PE heat shrink film and conveniently storing the PE heat shrink film; the setting of the upper plate, the adjusting bolt, the sleeve, the movable rod, the brush plate and the sponge layer is conducive to cleaning the dust adsorbed on the pressing wheel and improving the cleanliness of the film pressing device.

[0004] In practical applications, the above technical solution can only perform compression molding on the PE film, but it is difficult to flatten the wrinkles of the PE film caused by transportation and traction, which is not conducive to the subsequent winding operation of the PE film.

[0005] Therefore, it is necessary to invent a PE film wrinkle-proof pressing device to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1-3 A PE film wrinkle-proof pressing device shown in the figure comprises a support frame 1, a support plate 2 is fixedly arranged in the middle of the support frame 1, support rollers 3 are arranged at both ends of the support frame 1, a fixed frame 4 is fixedly arranged above the support frame 1, a pressing plate 5 is arranged below the fixed frame 4, fixed blocks 6 are fixedly arranged at both ends of the upper surface of the pressing plate 5, a movable arm 7 is movably arranged on the outer side of the fixed block 6 through a pin shaft, and the movable arm 7 is arranged in an "L" shape structure, and a pressing roller 8 is arranged on the inner side of the movable arm 7;

[0022] Specifically, a fixed frame 9 is fixedly provided in the middle of the upper surface of the pressing plate 5, and holes 10 are penetrated on both sides of the fixed frame 9, and a plug rod 11 is penetrated inside the plug hole 10, and a connecting seat 12 is fixedly provided at one end of the plug rod 11, and connecting arms 13 are movably provided at both ends of the connecting seat 12 through a pin shaft, and one end of the connecting arm 13 is movably connected to one end of the movable arm 7 through a pin shaft, and a movable plate 14 is provided inside the fixed frame 9, and a spring 15 is provided between the movable plate 14 and the plug rod 11. The setting of the spring 15 allows the clamping roller 8 to have a certain travel space, thereby ensuring the clamping effect of the clamping roller 8 on the PE film without affecting the movement of the pressing plate 5;

[0023] More specifically, a thread groove 16 is provided through the middle of the movable plate 14, a double-headed screw 17 is provided through the inside of the thread groove 16, and both ends of the double-headed screw 17 are movably connected to the inner wall of the fixed frame 9 through bearings, and a rubber sheath is sleeved in the middle of the double-headed screw 17. The double-headed screw 17 is used to adjust the initial position of the movable plate 14, thereby adjusting the initial position of the pressure roller 8;

[0024] In addition, a bracket 18 is fixedly installed in the middle of the upper surface of the pressing plate 5, and the bracket 18 is arranged above the fixed frame 9. A hydraulic rod 19 is fixedly installed on the upper surface of the bracket 18, and the top end of the hydraulic rod 19 is fixedly installed in the middle of the lower surface of the fixed frame 4. The hydraulic rod 19 is used to drive the pressing plate 5 to complete the film pressing operation.

[0025] Working principle of this utility model:

[0026] When the device is in use, the PE film to be processed is pulled so that it passes through the support roller 3 and reaches the top of the support plate 2. At this time, the hydraulic rod 19 drives the pressing plate 5 to move downward through the bracket 18, and the pressing plate 5 drives the pressing roller 8 to move downward. The pressing roller 8 can generate pressure on both ends of the PE film, so that the two ends of the PE film move downward. At this time, the wrinkles on the PE film are flattened. At this time, the PE film is in a fully unfolded state. At this time, the pressing roller 8 stops moving, and the pressing roller 8 acts on the insertion rod 11 through the movable arm 7, the connecting arm 13, and the connecting seat 12, so that the insertion rod 11 squeezes the spring 15, causing the spring 15 to deform. At this time, the pressing roller 8 stops moving and the pressing plate 5 can continue to press down. The pressing plate 5 cooperates with the support plate 2 to achieve film pressing processing of the PE film;

[0027] When processing a PE film with many wrinkles, the double-headed screw 17 can be rotated so that the double-headed screw 17 drives the movable plate 14 to move, and the movable plate 14 can drive the insertion rod 11 to move through the spring 15, so that the initial position of the clamping roller 8 can be adjusted, and then the movement stroke of the clamping roller 8 can be adjusted to ensure that when the clamping roller 8 acts on the PE film, the two ends of the PE film move a longer distance and the stretching effect is better, so as to ensure that the wrinkles can be fully opened.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
