Description

Technical Field

[0001] The invention relates to the technical field of corona machines, in particular to a double-sided corona machine with a retractable and unreeling belt. Background Art

[0002] The corona principle applies high-voltage and high-frequency current to arc-shaped discharge electrodes, generating small, dense blue-purple sparks between the electrodes to ionize the air. The plasma generated by the air ionization is accelerated under the action of a strong electric field and impacts the surface of the polymer such as the processed foil. The energy of the plasma particles can induce chemical bond rupture and molecular degradation on the polymer surface, forming carbonyl and nitrogen-containing polar groups on the surface molecular chains, which significantly increases the surface tension of the material, and the material surface is coarsened due to the strong ion impact; the synergistic effect significantly improves the adhesion of the processed material, while achieving plasma surface activation and treatment of the foil, thereby improving the surface energy, wettability and adhesion of PET.

The outer wall of the outer sleeve 17 is slidably connected to a small sliding sleeve 18, and the small sliding sleeve 18 is fixedly connected to the inner wall of the tooth groove 26 to the translation component 25. The reason why the present invention adopts the structural arrangement of the small sliding sleeve 18 is that when cleaning the shaft roller, it can not only directly wipe the shaft roller when it rotates, but also move laterally on the shaft roller, so that dust on the outer part of the shaft roller can be directly swept off, and in conjunction with the movement of the cleaning belt 14, it can reduce the adhesion of dust on the cleaning belt 14, ensuring the cleaning effect. At the same time, there are two cleaning directions, longitudinal and transverse, during cleaning, which can improve the cleaning effect.

[0035] Among them, the corona control cabinet 10 is located on the side of the corona action conveying roller group 6 away from the corona roller drive module 4, the outer wall of the corona control cabinet 10 is fixedly connected to one end of the corona generating module 5, and the exhaust ozone treatment cabinet 11 is located on the side of the unwinding roller group 3 away from the unwinding drive module 1. The material to be treated is unwound from the unwinding air shaft 2, and passes through the unwinding roller group 3, the corona action conveying roller group 6 and the winding roller group 8 in turn, and is finally wound up by the winding air shaft 9.

[0036] Among them, the internal rotation of the translation assembly 25 is connected to a gear 27, the outer wall of the gear 27 is meshed with the tooth groove 26, the shaft of the gear 27 is fixedly connected to a worm wheel 28, the outer wall of the worm wheel 28 is meshed with a worm 29, the worm 29 is rotatably connected to the inner wall of the translation assembly 25, and both ends of the worm 29 are fixedly connected to a square block 30. The inner wall of the translation assembly 25 is fixedly connected to two positioning blocks 34, and the inner wall of each positioning block 34 is slidably connected to a pushing block 31. The two pushing blocks 31 are diagonally distributed with the worm 29 as the center. An inclined groove is provided on the top of each pushing block 31 near the side of the square block 30, and the bottom outer wall of the inclined groove is rotatably connected to a rotating piece 32 for resisting the rotation of the square block 30. The bottom of the positioning block 34 is fixedly connected to a second spring 35, and the bottom of the second spring 35 is fixedly connected to a lower top block 33, which is installed below the pushing block 31.

[0037] Among them, the outer wall of the pushing block 31 is provided with a movable groove 40, one end of the rotating piece 32 is rotatably connected to the inner wall of the movable groove 40 through a set pin, and the inner wall of the movable groove 40 is fixedly connected with a limit block 42 for limiting the rotating piece 32.

[0038] Among them, the bottom of each pushing block 31 is fixedly connected to an electric push rod 39, the lower end of the electric push rod 39 is fixedly connected to the top of the lower top block 33, and the outer walls of both ends of the small sliding sleeve 18 are fixedly connected to a control switch 38, and the control switch 38 is electrically connected to the corresponding electric push rod 39. The two control switches 38 can respectively contact the two ends of the outer sleeve 17, and then respectively control the corresponding electric push rod 39.

[0039] Among them, the bottom of the translation component 25 is slidably connected to a movable plate 36, and the top of the movable plate 36 is provided with two storage grooves 37 corresponding to the two lower top blocks 33 respectively. When one of the electric push rods 39 matching the control switch 38 is in an extended state, that is, one of the lower top blocks 33 will extend out of the interior of the storage groove 37, so that when the movable plate 36 moves upward, it will directly push one of the push blocks 31 to move upward, and the other lower top block 33 slowly enters the interior of the storage groove 37, that is, the other push block 31 will not move upward, and the rotating piece 32 on the upward pushing block 31 will conflict with the edge of the square block 30, and as it moves upward, it will push the square block 30 to rotate, allowing the square block 30 to rotate ninety degrees.

[0040] Among them, the outer wall of the small sliding sleeve 18 is provided with several parallel sliding grooves 43, and the inner walls of the several sliding grooves 43 are slidably connected to a slider 44. The end of the cleaning belt 14 is fixedly connected with a telescopic clamping rod 45, and the telescopic clamping rod 45 is clamped in the middle of the slider 44. The telescopic clamping rod 45 adopts a sleeve-type multi-section structure design, and a clamping structure is provided at both ends for clamping the slider 44.

[0041] Among them, both ends of the outer sleeve 17 are fixedly connected with discs, and several evenly distributed limit rods 46 are fixedly connected between the discs. The outer wall of the limit rod 46 is slidably connected to the small sliding sleeve 18. The setting of the limit rod 46 is used to limit the small sliding sleeve.

[0042] Working principle: This device can be used to process materials such as copper foil and aluminum foil. When in use, the material to be processed is unwound from the unwinding air shaft 2, and first passes through the unwinding feed roller group 3 to smooth and correct the deviation. The constant tension of the product during feeding is 30~300N, and the edge is aligned within ±1.0mm. The corona action conveyor roller group 6 is equipped with two groups of corona rollers and two groups of electrode racks. Each group of electrode racks is distributed with about 10 ceramic electrodes. After the double-sided corona operation is completed, it passes through the rewinding feed roller group 8 to smooth and correct the deviation, and finally is rewound by the rewinding air shaft 9.

[0043] Furthermore, after a shift is completed, the material roll is removed from the unwinding air shaft 2 and the winding air shaft 9, and then the unwinding set 12 is installed on the unwinding air shaft 2, and the winding set 13 is installed on the winding air shaft 9. The unwinding roller group 3, the corona roller drive module 4 and the winding drive module 7 can be used as a reference to control the unwinding air shaft 2 to rotate clockwise and the winding air shaft 9 to rotate counterclockwise. When the inner sleeve 16 rotates, the top block 21 will gradually slide to the inclined surface of the long slide 19, so that the top block 21 squeezes The first spring 22, the mounting block 23 near the tooth groove 26 and the push plate 41 will be pushed up by the push rod 47, and the remaining mounting blocks 23 are fixed inside the mounting hole 20 and will not be pushed up. All the first springs 22 are compressed, and then the push block 21 contacts the outer wall of the inner sleeve 16. Through the friction between the push block 21 and the inner sleeve 16, the outer sleeve 17 is driven to rotate together with the inner sleeve 16 until the cleaning belt 14 is straightened and the elastic belt 15 is stretched. Since the push plate 41 is pushed upward, the push plate 41 will squeeze the movable plate 36;

[0044] One of the electric push rods 39 that matches the control switch 38 is in an extended state, that is, one of the lower top blocks 33 will extend out of the interior of the storage groove 37, so that when the movable plate 36 moves upward, it will directly push one of the push blocks 31 to move upward, and the other lower top block 33 will slowly enter the interior of the storage groove 37, that is, the other push block 31 will not move upward, and the rotating piece 32 on the upward push block 31 will contact the edge of the square block 30, and as it moves upward, it will push the square block 30 to rotate, allowing the square block 30 to rotate ninety degrees, thereby driving the worm 29 to rotate through the worm gear 28, allowing the gear 29 to rotate. The wheel 27 rotates, causing the small sliding sleeve 18 to move a short distance along the tooth groove 26 as a whole. Then, when it resets, the edge of the square block 30 presses the rotating piece 32 to retract, and under the pressure, the square block 30 is pressed against the edge of the push block 31, keeping the square block 30 flush. Then, after the movable plate 36 falls, the push block 31 also falls under the elastic force of the second spring 35, completing a single action. Each subsequent time the top block 21 is squeezed, the gear 27 will rotate, causing the small sliding sleeve 18 to move a short distance along the tooth groove 26 as a whole, so that the surfaces of all shaft rollers can be wiped by the lateral movement of the cleaning belt 14;

[0045] As the inner sleeve 16 continues to rotate, the top block 21 slides along the surface of the inner sleeve 16, and the top block 21 will fall into the inside of the long slide 19 again. The friction between the top block 21 and the inner sleeve 16 disappears. Under the elastic pulling of the elastic belt 15, the sliding arrangement of the slider 44 and the slide 43 will pull the cleaning belt 14 toward the winding air shaft 9, thereby driving all the transmission rollers to rotate a certain angle. When the top block 21 hits the outer wall of the inner sleeve 16 again, the cleaning belt 14 is straightened toward the unwinding set 12, and the elastic belt 15 is stretched. All the shaft rollers that cannot rotate will be wiped by the movement of the cleaning belt 14. The shaft rollers are wiped in both horizontal and vertical directions, and the ground is wiped more cleanly.

[0046] When the small sliding sleeve 18 moves to the end of the outer sleeve 17, the control switch 38 will conflict with the disc at the end of the outer sleeve 17, thereby pressing one of the control switches 38, so that the control switch 38 sends a signal to control the corresponding electric push rod 39 to extend and the electric push rod 39 that does not correspond to it to retract, so that when the movable plate 36 moves up again, it conflicts with the other push block 31, and when the other push block 31 moves up, it conflicts with the square block 30 and causes the worm 29 to reverse, thereby realizing the function of automatic steering, saving time. A large amount of manpower is required. During cleaning, it is only necessary to install the unwinding set 12 and the rewinding set 13. After the cleaning belt 14 passes through the roller, the two ends are connected to complete the automatic cleaning. It can be completed automatically without manual operation. After the cleaning is completed, it is only necessary to remove the unwinding set 12, install a new material roll, extend the telescopic clamping rod 45 at the end of the cleaning belt 14, clamp the end of the material roll with the claws at both ends, and then complete the automatic threading process of aluminum foil or copper foil by clockwise rotation of the unwinding air shaft 2 and the rewinding air shaft 9.

[0047] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are common means well known to those skilled in the art.

[0048] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
