Description

Technical Field

[0001] This utility model relates to the field of polypropylene film technology, specifically a PP film composite embossing device. Background Technology

[0002] Polypropylene film is a thin film material made primarily of polypropylene. It possesses numerous excellent properties, such as high mechanical strength, capable of withstanding certain tensile and tearing forces; good chemical stability, not easily corroded by chemicals; good heat resistance, maintaining stable performance at high temperatures; and also moisture-proof, waterproof, and breathable properties. Polypropylene film has wide applications in many fields, including packaging, electronics, medical, and agriculture. For example, it is used in food packaging to extend shelf life, in the electronics industry for insulation protection, and in the medical field as packaging material or covering material for surgical instruments.

[0003] In existing technologies, plasma treatment can be used to treat impurities on the surface of polypropylene films. The specific process involves placing the polypropylene film in a plasma treatment device, where a high-frequency electric field is generated by a radio frequency power supply. This field causes the reactant gases (such as argon or oxygen) to form plasma. High-energy particles in the plasma collide with impurities on the polypropylene film surface, energizing the impurity molecules and causing them to be excited, ionized, or decomposed, thereby achieving the purpose of removing the impurities.

[0004] This method requires specialized plasma treatment equipment, which is costly and has strict operational requirements, requiring professional personnel for operation and maintenance. During the treatment process, parameters such as the type, flow rate, pressure, treatment time, and power of the reaction gas must be precisely controlled; otherwise, the impurity treatment effect may be affected, and it may be impossible to efficiently treat impurities on the surface of the polypropylene film. To address the above problems, a PP film composite embossing device is proposed. Utility Model Content

A threaded block 4 is threadedly connected to the outer ring of the first lead screw 3. The rotation of the first lead screw 3 causes the threaded block 4 to move back and forth. A housing 5 is slidably connected to the front end of the inner wall of the base plate 1. The movement of the threaded block 4 causes the housing 5 to move synchronously. A second motor 6 is fixedly connected to the inner wall of the housing 5. The housing 5 protects the internal motor. A bidirectional threaded rod 30 is fixedly connected to the output end of the second motor 6.

A second gear 22 is fixedly connected to the output end of the fifth motor 21, driving the second gear 22 to rotate synchronously. Second frames 23 are slidably connected to both ends of the first fixed plate 17, limiting the movement of the second frames 23, which can only move left and right. A rack 24 is fixedly connected to the front end of the inner wall of the second frame 23, and its movement causes the second frame 23 to move synchronously. The rack 24 is meshed with the second gear 22. The rotation of the second gear 22 causes the rack 24 to move. The second frame 23 has straightening rollers 25 that are rotatably connected through both sides. The bottom of the first fixed plate 17 is fixedly connected to the gear ring 20. The rotation of the gear ring 20 causes the first fixed plate 17 to swing. The middle of the inner wall of the base plate 1 is fixedly connected to the fourth motor 18. The output end of the fourth motor 18 is fixedly connected to the first gear 19, and the first gear 19 and the gear ring 20 are meshed with each other. The rotation of the first gear 19 causes the gear ring 20 to rotate synchronously.

[0038] Working Principle: First, the vision sensor 29 detects foreign objects on the surface of the polypropylene film. During the detection process, the information is fed back to the control cabinet 33. The control cabinet 33 controls the motors within the device to generate drives. First, the second motor 6 drives the bidirectional threaded rod 30 to rotate. The rotation of the bidirectional threaded rod 30 connects the first frame 7. The first motor 2 drives the first lead screw 3 to rotate. The rotation of the first lead screw 3 moves the first frame 7 back and forth, allowing the brush plate 13 and scraper 14 to scrape and wipe the surface of the polypropylene film, facilitating the removal of foreign objects. The third motor 9 drives the second lead screw 10 to rotate. The limiting rod 11 causes the two second lead screws 10 to rotate synchronously. The rotation of the second lead screw 10 moves the push plate 15, which pushes out clothing and allows foreign objects to enter the collection box 16, thus facilitating the removal of foreign objects and the cleaning of the polypropylene film. During the embossing process, the fifth motor 21 starts, and its output end drives the second gear 22 to rotate. Because the second gear 22 meshes with the rack 24, according to the transmission principle of the rack and pinion 24, the rack 24 will move under the drive of the second gear 22. Since the rack 24 is fixed to the front end of the inner wall of the second frame 23, the second frame 23 will move along the sliding direction at both ends of the first fixed plate 17. When the second frame 23 moves, the position of the correction rollers 25 that are connected to it on both sides also changes accordingly. In this way, the direction of travel of the PP film can be adjusted, which plays a correction role. The fourth motor 18 starts, and the first gear 19 at its output end rotates. Since the first gear 19 meshes with the gear ring 20, it will drive the gear ring 20 to rotate. The gear ring 20 is fixed to the bottom of the first fixed plate 17, thereby causing the first fixed plate 17 and the correction components on it to rotate as a whole. The angle of the correction rollers 25 can be further adjusted to achieve more precise correction.
