Description

Technical Field

[0001] The utility model relates to the technical field of plasma equipment, in particular to a plastic film machine capable of realizing large-range plasma treatment. Background Art

[0002] Plasma, also called plasma, is an ionized gaseous substance composed of positive and negative ions generated after partial electrons are deprived from atoms and atomic clusters. It is a macroscopic electrically neutral ionized gas with a scale larger than the Debye length. Its motion is mainly governed by electromagnetic forces and exhibits significant collective behavior. It exists widely in the universe and is often regarded as the fourth state of matter in addition to solids, liquids, and gases. Plasma is a good conductor of electricity, and by using a cleverly designed magnetic field, plasma can be captured, moved, and accelerated. The development of plasma physics provides new technologies and processes for the further development of sciences such as materials, energy, information, environmental space, space physics, and geophysics.

[0003] The moisture on the ground in the vegetable greenhouse evaporates, and the water vapor generated by the respiration of green plants such as vegetables at night meets the relatively low-temperature plastic agricultural film. The water vapor condenses when it meets the cold, and the generated water droplets adhere to the plastic agricultural film. Since the existing film is only treated on the surface and there are a large number of toxic substances attached inside the film, after reacting with the toxic substances in the condensed water, it drips onto the crops, which is likely to cause harm to the crops. Content of the Utility Model

[0004] The purpose of the utility model is to provide a plastic film machine capable of realizing large-range plasma treatment. Its advantages are: performing double-sided plasma treatment on the plastic film, and the winding roller winds up the treated plastic film. The treated plastic film has the effects of anti-condensation, heat preservation, and light transmission, so as to better grow crops.

High-voltage discharge components parallel to the corona rollers are symmetrically arranged on the frame. The transformer is electrically connected to the high-voltage discharge components. The plastic film passes from the unwinding roller through the gap between the corona rollers and the high-voltage discharge components.

[0006] Through the above technical solution, the agricultural film to be processed is sleeved on the unwinding roller, and the unwinding roller is installed on the frame.

At this time, the driving member drives the corona roller to rotate, and the corona roller drives the agricultural film to rotate. When the agricultural film passes through between the corona roller and the high-voltage discharge components, the corona roller serves as a low-voltage electrode to perform electro-ion treatment on the surface of the agricultural film, and a layer of film is applied to the surface of the agricultural film. By setting two groups of high-voltage discharge components and corona rollers, double-sided plasma treatment is performed on the agricultural film, and the winding roller winds up the processed agricultural film. The processed agricultural film has the effects of anti-condensation, heat preservation and light transmission, so as to better plant crops.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following further describes the present invention in detail with reference to the accompanying drawings.

[0020] Embodiment: Refer to as Figures 1-5As shown in the figure, a plastic film machine capable of realizing large-range plasma treatment includes a frame 1 and a transformer 6 provided on one side of the frame 1.

Two corona rollers 4 located between the film unwinding roller 2 and the winding roller 3 are rotatably connected to one side of the frame 1 through a driving member. The driving member includes a base 7. A variable-frequency motor 8 is fixedly connected to the base 7. The output end of the variable-frequency motor 8 is coaxially connected to a rotating shaft 9. A first runner 10 is connected to the end of the rotating shaft 9. Two speed reducers 12 are symmetrically installed on the base 7. A second runner 11 is connected between the two speed reducers 12 through an input shaft. The first runner 10 and the second runner 11 are connected by a belt. The output shaft of the speed reducer 12 is connected to a first gear 16. Magnetic powder clutches 13 are symmetrically connected to the base 7. The input shaft of the magnetic powder clutch 13 is connected to a second gear 17 that is belt-connected to the first gear 16. The output shaft of the magnetic powder clutch 13 is connected to a first sprocket 14. A second sprocket 15 is fixedly connected to one side of the corona roller 4. The first sprocket and the second sprocket 15 are connected by a chain. High-voltage discharge assemblies 5 parallel to the corona roller 4 are symmetrically arranged on the frame 1. The transformer 6 is electrically connected to the high-voltage discharge assemblies 5. The plastic film passes through the gap between the corona roller 4 and the high-voltage discharge assemblies 5 after passing through the film unwinding roller 2;

[0021] Specifically, the plastic film to be processed is sleeved on the film unwinding roller 2. The film unwinding roller 2 is installed on the frame 1. The film unwinding roller 2 unwinds the plastic film at a constant speed, so that the plastic film passes through between the two corona rollers 4 and the high-voltage discharge assemblies 5 in sequence, and then winds around the winding roller 3. The variable-frequency motor 8 is driven. The variable-frequency motor 8 drives the rotating shaft 9 to rotate. The rotating shaft 9 drives the first runner 10 to rotate. The first runner 10 drives the second runner 11 to rotate. The input speed is reduced and the output torque is increased through the speed reducer 12. Then the output shaft drives the first gear 16 to rotate. The first gear 16 drives the second gear 17 to rotate. Through the magnetic powder clutch 13, the first sprocket 14 is driven to rotate. The first sprocket 14 drives the second sprocket 15 to rotate, so that the rotation speed of the corona roller 4 matches the rotation speed of the plastic film. In this way, the corona roller 4 can be driven to rotate with a very small force. When there is a problem with the rotation speed of the corona roller 4, the operator can easily stop the rotation of the corona roller 4. At this time, the corona roller 4 drives the plastic film to rotate. When the plastic film passes through the gap between the corona roller 4 and the high-voltage discharge assemblies 5, the corona roller 4 serves as a low-voltage electrode to perform electro-ion treatment on the surface of the plastic film, and a layer of film is applied to the surface of the plastic film. By setting two high-voltage discharge assemblies 5 and the corona roller 4, double-sided plasma treatment is performed on the plastic film. The winding roller 3 winds the processed plastic film. The processed plastic film has the effects of anti-condensation, heat preservation and light transmission, so as to better grow crops.

[0022] Further, a flipping cylinder 19 connected to the high-voltage discharge assembly 5 is installed on the frame 1. The flipping cylinder 19 is driven. The flipping cylinder 19 drives the high-voltage discharge assembly 5 to rotate, and the gap between the high-voltage discharge assembly 5 and the corona roller 4 is adjusted to facilitate the operator to pass the plastic film through.

An opening and closing sensor 22 is installed on one side of the frame 1 away from the limiting plate 20. A second stop rod 23 is provided on the high-voltage discharge component 5. During the rotation of the high-voltage discharge component 5 driven by the flipping air cylinder 19, the limiting plate 20 plays a limiting role on the first stop rod 21, enabling the high-voltage discharge component 5 to better return to its original position. When the second stop rod 23 touches the opening and closing sensor 22, the opening and closing sensor 22 emits a signal, facilitating personnel to promptly discover problems during the rotation of the high-voltage discharge component 5.

[0024] Further, a protective cover 18 is installed on the base 7, and an opening is provided on the side of the protective cover 18 facing the frame 1. The protective cover 18 plays a protective role for the driving device.

[0025] Operation steps: Put the agricultural film to be processed on the unwinding roller 2. The unwinding roller 2 is installed on the frame 1. The unwinding roller 2 unwinds the agricultural film at a constant speed, enabling the agricultural film to pass through between two groups of corona rollers 4 and the high-voltage discharge component 5 in sequence, and then wind around the winding roller 3. Drive the variable-frequency motor 8. The variable-frequency motor 8 drives the rotating shaft 9 to rotate. The rotating shaft 9 drives the first runner 10 to rotate. The first runner 10 drives the second runner 11 to rotate. The input speed is reduced and the output torque is increased through the speed reducer 12. Then, the output shaft drives the first gear 16 to rotate. The first gear 16 drives the second gear 17 to rotate. Through the magnetic powder clutch 13, the first sprocket 14 is driven to rotate. The first sprocket 14 drives the second sprocket 15 to rotate, enabling the rotation speed of the corona roller 4 to match the rotation speed of the agricultural film. In this way, the corona roller 4 can be driven to rotate with a very small force. When there is a problem with the rotation speed of the corona roller 4, personnel can easily stop the rotation of the corona roller 4. At this time, the corona roller 4 drives the agricultural film to rotate. When the agricultural film passes between the corona roller 4 and the high-voltage discharge component 5, the corona roller 4 serves as a low-voltage electrode to perform electro-ion treatment on the surface of the agricultural film, and a layer of film is applied to the surface of the agricultural film. By setting two groups of high-voltage discharge components 5 and corona rollers 4, double-sided plasma treatment is performed on the agricultural film. The winding roller 3 winds up the processed agricultural film. The processed agricultural film has the effects of anti-condensation, heat preservation, and light transmission, thus better facilitating the planting of crops. Drive the flipping air cylinder 19. The flipping air cylinder 19 drives the high-voltage discharge component 5 to rotate, adjusting the gap between the high-voltage discharge component 5 and the corona roller 4 to facilitate personnel to pass the agricultural film through. During the rotation of the high-voltage discharge component 5 driven by the flipping air cylinder 19, the limiting plate 20 plays a limiting role on the first stop rod 21, enabling the high-voltage discharge component 5 to better return to its original position. When the second stop rod 23 touches the opening and closing sensor 22, the opening and closing sensor 22 emits a signal, facilitating personnel to promptly discover problems during the rotation of the high-voltage discharge component 5. The protective cover 18 plays a protective role for the driving device.
