Description

Technical Field

[0001] The present invention relates to the technical field of corona machines, and in particular to a double-sided corona machine with unwind and rewind functions. Background Art

[0002] The corona principle is to apply a high-voltage high-frequency current to an arc-shaped discharge electrode, generating fine and dense blue-violet sparks between the electrodes to ionize the air. The plasma generated by this air ionization accelerates under the action of a strong electric field and impacts the surface of polymer materials such as the foils to be processed. The energy of the plasma particles can induce the breaking of chemical bonds and the degradation of surface molecules of the polymer, forming carbonyl and nitrogen-containing polar groups on the surface molecular chains, significantly increasing the surface tension of the material, and roughening the surface of the material due to the impact of strong ions; the synergistic effect significantly improves the adhesion of the material to be processed, and at the same time realizes plasma surface activation and treatment of the foil, improving the surface energy, wetting ability, and adhesiveness of PET.

[0014] Compared with the existing technology, the present invention has the following beneficial effects: 1. By arranging the inner sleeve in the present invention, as the inner sleeve continuously rotates, the top block slides along the surface of the inner sleeve. The top block will fall into the long sliding groove again, and the friction between the top block and the inner sleeve disappears. Under the elastic stretching of the elastic belt, with the sliding arrangement of the slider and the sliding groove, the cleaning belt will be pulled to move a part towards the winding air shaft, thereby driving all the transmission rollers to rotate a certain angle. When the top block touches the outer wall of the inner sleeve again, the cleaning belt is straightened towards the direction of the unwinding sleeve group again, and the elastic belt is stretched. All the rollers that cannot rotate will be wiped on the surface under the movement of the cleaning belt, so that the rollers are wiped in both the horizontal and vertical directions, and the wiping is cleaner. 2. When the small sliding sleeve moves to the end of the outer sleeve, the control switch will touch the disc at the end of the outer sleeve, thereby pressing one of the control switches, causing the control switch to send a signal to control the elongation of the corresponding electric push rod and the retraction of the non-corresponding electric push rod. Thus, when the movable plate moves up again, the other pushing block will be touched. When the other pushing block moves up, it will touch the square block and make the worm reverse, thereby realizing the function of automatic steering, saving a lot of manpower. When cleaning, only need to install the unwinding sleeve group and the winding sleeve group, pass the cleaning belt through the roller shaft, and connect the two ends to complete, then it can be automatically cleaned without manual operation. Moreover, after cleaning, only need to disassemble the unwinding sleeve group, install a new material roll, stretch the telescopic clamping rod at the end of the cleaning belt, clamp the end of the material roll through the clamping claws at both ends, and then through the clockwise rotation of the unwinding air shaft and the winding air shaft, the automatic threading process of the aluminum foil or copper foil can be completed.

One-way ratchet structures are installed at both ends of all the shafts and rollers. When an external force is applied to rotate all the shafts and rollers clockwise, they can rotate, but they cannot rotate counterclockwise. An unwinding sleeve group 12 is sleeved outside the unwinding air shaft 2. A winding sleeve group 13 is sleeved outside the winding air shaft 9. The unwinding sleeve group 12 and the winding sleeve group 13 have the same structure and are mirror images of each other. A cleaning belt 14 is connected between the unwinding sleeve group 12 and the winding sleeve group 13. An elastic belt 15 is fixedly installed at one end of the cleaning belt 14 close to the winding sleeve group 13.

[0020] Among them, both the unwinding sleeve group 12 and the winding sleeve group 13 include an inner sleeve 16. The outer wall of the inner sleeve 16 is rotatably connected to an outer sleeve 17. A plurality of uniformly distributed long sliding grooves 19 are formed in the outer wall of the inner sleeve 16. One end of each long sliding groove 19 is a slope. A plurality of mounting holes 20 corresponding to the long sliding grooves 19 are formed in the interior of the outer sleeve 17. Each mounting hole 20 is internally provided with a mounting hole 20, a top block 21, a first spring 22 and a mounting block 23. The outer wall of the top block 21 is slidably connected to the inner wall of the mounting hole 20. The bottom of the top block 21 is matched with the long sliding groove 19.

A top rod 47 for jacking up the mounting block 23 is fixedly connected to the top of the top block 21. A small sliding sleeve 18 is slidably connected to the outer wall of the outer sleeve 17. A translation assembly 25 is fixedly connected to the inner wall of the small sliding sleeve 18 close to the toothed groove 26. The reason why the small sliding sleeve 18 is adopted in the present invention is that when cleaning the shaft roller, not only can it directly wipe when the shaft roller rotates, but also it can laterally move on the shaft roller, directly sweeping off some dust on the outside of the shaft roller. Moreover, in cooperation 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.

[0021] 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. The exhaust ozone treatment cabinet 11 is located on the side of the unwinding material passing roller group 3 away from the unwinding drive module 1. The material to be treated is unwound from the unwinding air shaft 2, and successively passes through the unwinding material passing roller group 3, the corona action conveying roller group 6 and the winding material passing roller group 8, and is finally wound by the winding air shaft 9.

[0022] Among them, a gear 27 is rotatably connected inside the translation component 25. The outer wall of the gear 27 meshes with the tooth groove 26. A worm gear 28 is fixedly connected to the shaft rod of the gear 27. The outer wall of the worm gear 28 meshes with a worm 29. The worm 29 is rotatably connected to the inner wall of the translation component 25. Square blocks 30 are fixedly connected to both ends of the worm 29. Two positioning blocks 34 are fixedly connected to the inner wall of the translation component 25. A pushing block 31 is slidably connected to the inner wall of each positioning block 34. The two pushing blocks 31 are distributed diagonally with the worm 29 as the center. An inclined groove is formed on the top of each pushing block 31 near one side of the square block 30. A rotating piece 32 for abutting against the rotation of the square block 30 is rotatably connected to the bottom outer wall of the inclined groove. A second spring 35 is fixedly connected to the bottom of the positioning block 34. A lower top block 33 is fixedly connected to the bottom of the second spring 35.

[0023] Among them, an activity groove 40 is formed on the outer wall of the pushing block 31. One end of the rotating piece 32 is rotatably connected to the inner wall of the activity groove 40 through a set pin. A limiting stop block 42 for limiting the rotating piece 32 is fixedly connected to the inner wall of the activity groove 40.

[0024] Among them, an electric push rod 39 is fixedly connected to the bottom of each pushing block 31. The lower end of the electric push rod 39 is fixedly connected to the top of the lower top block 33. Control switches 38 are fixedly connected to the outer walls at both ends of the small sliding sleeve 18. The control switch 38 is electrically connected to its corresponding electric push rod 39. The two control switches 38 can respectively abut against both ends of the outer sleeve 17, thereby respectively controlling the corresponding electric push rods 39.

[0025] Among them, a movable plate 36 is slidably connected to the bottom of the translation component 25. Two receiving grooves 37 corresponding to the two lower top blocks 33 respectively are formed on the top of the movable plate 36. When one of the electric push rods 39 that matches the control switch 38 is in the extended state, that is, one of the lower top blocks 33 will extend out of the inside of the receiving groove 37. When the movable plate 36 moves upward, it will directly push one of the pushing blocks 31 upward. The other lower top block 33 slowly enters the inside of the receiving groove 37, that is, the other pushing block 31 will not move upward. The rotating piece 32 on the upward moving pushing block 31 will abut against the side of the square block 30. As it moves upward, it will push the square block 30 to rotate, causing the square block 30 to rotate by ninety degrees.

[0026] Among them, a plurality of parallel sliding grooves 43 are formed on the outer wall of the small sliding sleeve 18. A slider 44 is slidably connected to the inner walls of the plurality of sliding grooves 43 together. A telescopic clamping rod 45 is fixedly connected to the end of the cleaning belt 14. The telescopic clamping rod 45 clamps the middle of the slider 44. The telescopic clamping rod 45 adopts a sleeve-type multi-section structure design, and clamping structures are arranged at both ends for clamping the slider 44.

[0027] Among them, discs are fixedly connected to both ends of the outer sleeve 17, and a number of evenly distributed limiting rods 46 are fixedly connected between the discs. The outer wall of the limiting rod 46 is slidably connected to the small sliding sleeve 18. The limiting rod 46 is provided for limiting the small sliding sleeve.

[0028] Working principle: This device can be used for processing materials such as copper foil and aluminum foil. During use, the material to be processed is unrolled from the unwinding air shaft 2, and first passes through the unwinding guiding roller group 3 to be flattened and corrected. During the product feeding process, the constant tension is 30 - 300 N, and the edge alignment is ±1.0 mm. There are 2 corona rollers and 2 electrode frames at the corona conveying roller group 6. Each electrode frame is distributed with about 10 ceramic electrodes. After the double-sided corona operation is completed, it passes through the winding guiding roller group 8 to be flattened and corrected, and finally is wound by the winding air shaft 9. Furthermore, after a shift operation is completed, the material roll is removed from the unwinding air shaft 2 and the winding air shaft 9. Subsequently, the unwinding sleeve group 12 is installed on the unwinding air shaft 2, and the winding sleeve group 13 is installed on the winding air shaft 9. It can be combined Figure 3 、 Figure 4 and Figure 7 As a reference, control the unwinding air shaft 2 to rotate clockwise, and control 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 chute 19, causing the top block 21 to compress the first spring 22. The mounting block 23 and the push plate 41 near the tooth groove 26 will be lifted by the ejector rod 47, and the remaining mounting blocks 23 fixed inside the mounting hole 20 will not be lifted. All the first springs 22 are compressed. Subsequently, the top block 21 contacts the outer wall of the inner sleeve 16. Through the friction between the top 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 lifted upward, the push plate 41 will squeeze the movable plate 36; One of the electric push rods 39 that matches the control switch 38 is in the extended state. That is, one of the lower top blocks 33 will extend out of the inside of the storage groove 37. When the movable plate 36 moves upward, it will directly push one of the push blocks 31 upward. The other lower top block 33 slowly enters the inside of the storage groove 37, that is, the other push block 31 will not move upward. The rotating piece 32 on the upward-moving push block 31 will abut against the side of the square block 30. As it moves upward, it will push the square block 30 to rotate, causing the square block 30 to rotate 90 degrees. Thus, the worm 29 is driven to rotate by the worm gear 28, causing the gear 27 to rotate, so that the entire small sliding sleeve 18 moves a short distance along the tooth groove 26. Subsequently, when resetting, the side of the square block 30 will press the rotating piece 32 to retract, and under the extrusion, the side of the square block 30 will be in contact with the side of the push block 31 to keep the square block 30 flush. Subsequently, after the movable plate 36 drops, the push block 31 will also drop under the elastic force of the second spring 35 to complete a single action. After each subsequent top block 21 is squeezed, the gear 27 will rotate, causing the entire small sliding sleeve 18 to move a short distance along the tooth groove 26. Thus, the surface of all the shaft rollers can be wiped by the lateral movement of the cleaning belt 14; 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 long sliding groove 19 again. The friction between the top block 21 and the inner sleeve 16 disappears. Under the elastic stretching of the elastic belt 15, with the sliding arrangement of the slider 44 and the sliding groove 43, the cleaning belt 14 will be pulled towards the winding air expansion shaft 9 by a certain distance, thereby driving all the transmission rollers to rotate by a certain angle. When the top block 21 abuts against the outer wall of the inner sleeve 16 again, the cleaning belt 14 is straightened towards the unwinding sleeve group 12, and the elastic belt 15 is stretched. All the shaft rollers that cannot rotate will have their surfaces wiped by the movement of the cleaning belt 14, so that the shaft rollers are wiped in both the horizontal and vertical directions, and are wiped cleaner; Moreover, when the small sliding sleeve 18 moves to the end of the outer sleeve 17, the control switch 38 will abut against the disc at the end of the outer sleeve 17, thereby pressing one of the control switches 38, causing the control switch 38 to emit a signal, controlling the corresponding electric push rod 39 to extend, and the non-corresponding electric push rod 39 to retract. As a result, when the movable plate 36 moves upward again, it will abut against the other pushing block 31. When the other pushing block 31 moves upward, it will abut against the square block 30 and cause the worm 29 to reverse, thus realizing the function of automatic steering, saving a large amount of manpower. During cleaning, only need to install the unwinding sleeve group 12 and the winding sleeve group 13, pass the cleaning belt 14 through the roller shafts, and then connect the two ends to complete the automatic cleaning without further manual operation. Moreover, after the cleaning is completed, only need to disassemble the unwinding sleeve group 12, install a new material roll, stretch the telescopic clamping rod 45 at the end of the cleaning belt 14, clamp the end of the material roll with the clamping jaws at both ends, and then through the clockwise rotation of the unwinding air shaft 2 and the winding air shaft 9, the automatic threading process of the aluminum foil or copper foil can be completed.

[0029] Further explanation, the above fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or integrally formed setting, etc., which are common means well-known to those skilled in the art.

[0030] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
