Description

Technical Field

[0001] This utility model relates to the field of PE film processing technology, specifically to an anti-wrinkle pressing device for PE film flattening processing. Background Technology

[0002] The flattening process of PE (polyethylene) film is a key step in the film production and use process. Uneven PE film will cause problems such as inaccurate color registration, air bubbles, or skewed cutting during printing, lamination, or slitting. Flattening can significantly improve the processing accuracy.

[0003] A cutting device for processing plastic film, with patent publication number CN221365036U, includes a vertical cutting blade and a blade shaft. In use, the vertical cutting blade is first fitted onto the surface of the blade shaft, and then fixed in place by a blade-fixing rod. Additional vertical cutting blades can be added according to production needs. Then, the larger end of the blade shaft is placed in the groove of the shaft holder. The shaft holder is then rotated on the connecting shaft until it aligns with the shaft holder, and the fixing rod is rotated downwards to secure it. Next, the protective cover moves the upper end of the vertical cutting blade on the slide rail, covering the entire working position of the vertical cutting blade. Then, as needed, a third motor is activated to perform vertical cutting of the plastic film on the main body of the operating table. For horizontal cutting, a second motor is activated to drive the lifting rod on the turntable shaft, thereby moving the horizontal cutting blade on the blade holder connected to the connecting shaft to perform vertical and horizontal cutting of the film. After cutting, the neatly stacked plastic film is moved out of the cutting area by the film-shifting shaft installed on the first motor, and the lower pressing shaft, under the force of the lower push rod, causes the plastic film to be displaced evenly. This completes the process of using the device.

[0004] During the membrane fabric processing, when the membrane fabric is laid flat on the main body of the operating table, the local deformation caused by electrostatic adsorption can easily lead to wrinkles. This problem directly affects the processing accuracy and the quality of the finished product. In order to address the above problems, an anti-wrinkle pressing device for PE film laying is proposed.

[0011] In one alternative embodiment: the sliding assembly includes a sliding groove and a forward and reverse threaded rod. Two sets of sliding grooves are respectively opened on one side of two sets of fixed blocks that are close to each other. The forward and reverse threaded rods are rotatably connected in one set of sliding grooves. A slider is fixedly connected to one side of the moving block. Two sets of sliders are slidably connected in the sliding grooves. Each set of sliders has a threaded hole for cooperating with the rotation of the forward and reverse threaded rods. The two sets of threads on the forward and reverse threaded rods that correspond to the threaded holes have opposite directions. A motor for driving the forward and reverse threaded rods to rotate is installed on one side of one set of fixed blocks.

[0012] In one alternative embodiment: the drive assembly includes several sets of electro-hydraulic rods, which are mounted on the operating table, and the piston rods at the power output ends of the electro-hydraulic rods are fixedly connected to the bottom of the fixed block.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0024] Please see Figures 1-3 In this embodiment, the anti-wrinkle pressing device for PE film flattening includes an operating table 25, two sets of fixed blocks 11 and a rotating roller 12. The rotating roller 12 is provided on the side of the two sets of fixed blocks 11 that are close to each other. The rotating roller 12 rolls on the top of the operating table 25. Extension rods 17 are fixedly connected to both sides of the rotating roller 12. Two sets of moving blocks 13 are slidably connected on the side of the two sets of fixed blocks 11 that are close to each other. The moving blocks 13 are provided with support components for supporting the extension rods 17.

[0025] The support assembly includes a support block 14 and two sets of rotating plates 15. The support block 14 is fixedly connected to one side of the moving block 13. The two sets of rotating plates 15 are rotatably connected to both sides of the support block 14. The ends of the two sets of rotating plates 15 away from the support block 14 are rotatably connected to an extension rod 17. The moving block 13 is provided with a limiting member for limiting the rotation of the extension rod 17.

[0026] The fixed block 11 is provided with a sliding component for driving the moving block 13 to move, and the operating table 25 is provided with a driving component for adjusting the fixed block 11 up and down.

[0027] The limiting component includes a connecting plate 16 and a spring 18. The two ends of the connecting plate 16 are respectively fixedly connected to rotating plates 15. The spring 18 is disposed between the connecting plate 16 and the moving block 13. One end of the spring 18 is connected to one side of the connecting plate 16, and the side of the spring 18 away from the connecting plate 16 is connected to the moving block 13. As the rotating roller 12 moves, the two sets of rotating plates 15 rotate, and the spring 18 is stretched out under force, which can limit the rotation of the rotating plates 15.

[0028] The sliding assembly includes a sliding groove 21 and a forward and reverse threaded rod 20. Two sets of sliding grooves 21 are respectively opened on the side of two sets of fixed blocks 11 that are close to each other. The forward and reverse threaded rod 20 is rotatably connected in one set of sliding grooves 21. A slider 19 is fixedly connected to one side of the moving block 13. Two sets of sliders 19 are slidably connected in the sliding groove 21. Each set of sliders 19 has a threaded hole 24 for cooperating with the rotation of the forward and reverse threaded rod 20. The two sets of threads on the forward and reverse threaded rod 20 have opposite directions of rotation to the threaded hole 24. A motor 26 for driving the forward and reverse threaded rod 20 to rotate is installed on one side of one set of fixed blocks 11. When the motor 26 works, it drives the forward and reverse threaded rod 20 to rotate. As the forward and reverse threaded rod 20 rotates, the two sets of sliders 19 move in opposite directions in the sliding groove 21, causing the rotating roller 12 to roll on the membrane cloth, smoothing out the deformation and wrinkles on the membrane cloth caused by static electricity.

[0029] The drive assembly includes several sets of electro-hydraulic rods 23, which are mounted on the operating table 25. The piston rods at the power output ends of the electro-hydraulic rods 23 are fixedly connected to the bottom of the fixed blocks 11. When the electro-hydraulic rods 23 retract, the two sets of fixed blocks 11 drive the rotating rollers 12 to move downwards, which allows the rotating rollers 12 to move up and down, facilitating the laying of the membrane.

[0030] Another set of guide rods 22 are fixedly connected in the sliding groove 21, and the other two sets of sliders 19 are provided with sliding holes for the guide rods 22 to pass through. By setting the guide rods 22, the sliding of the other two sets of moving blocks 13 can be guided.

[0031] The surface of the rotating roller 12 is provided with guide rubber. By providing guide rubber, scratches on the film cloth caused by the rotating roller 12 during the smoothing process can be reduced.

[0032] The working principle of this utility model is as follows: During use, the electric hydraulic rod 23 retracts, causing the two sets of fixed blocks 11 to drive the rotating rollers 12 to move downwards and contact the membrane cloth. As the fixed blocks 11 move downwards, the two sets of rotating rollers 12 are subjected to force and roll and move on the membrane cloth. The rotating rollers 12 drive the extension rod 17 to rotate. At the same time, as the rotating rollers 12 move, the two sets of rotating plates 15 rotate, the spring 18 is subjected to force and extends, the motor 26 works, and drives the positive and negative threaded rods 20 to rotate. As the positive and negative threaded rods 20 rotate, the two sets of sliders 19 move in opposite directions in the slide groove 21, causing the rotating rollers 12 to roll on the membrane cloth, smoothing out the deformation and wrinkles on the membrane cloth caused by static electricity, avoiding wrinkles during processing, and improving the processing accuracy and the quality of the finished product.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
