Description

Technical Field

[0001] The invention relates to the technical field of corona machines, in particular to a high-density ceramic chamber corona machine. Background Art

[0002] Corona machine, also known as corona treatment machine, electron impact machine or electric spark machine, is academically called dielectric barrier discharge. Corona machine is mainly used for surface treatment of plastic film or plastic sheet products.

[0003] The working principle of the corona machine is to use a high-frequency high-voltage power supply to generate corona between the discharge electrode and the corona roller to form a low-temperature plasma zone. The air between the two electrodes is ionized to produce ozone, an oxidant, which can immediately change the molecular structure of the plastic surface, converting it from non-polar to polar. At the same time, corona treatment will cause tiny uneven holes on the surface of the material, making it rough, enhancing surface activity, and thus increasing surface tension.

[0004] Most of the existing high-density ceramic chamber corona machines often use a whole piece of long strip electrode. Since the long strip electrode is integral, the electrode length cannot be adjusted accordingly according to the width of the film to be corona treated, and the flexibility is poor. When corona treating films of different widths, the electrode length cannot be adjusted, so that there will be local electrodes that do not corona the film and achieve empty charge. Empty charge will not only damage the corona roller, but also cause power waste. Summary of the invention

DETAILED DESCRIPTION

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] The embodiment of the present application solves the problem that most high-density ceramic bin corona machines often use a whole piece of long strip electrode. Since the long strip electrode is a whole piece, it is impossible to adjust the electrode length accordingly according to the width of the film 5 to be corona treated, and the flexibility is poor. When corona treating films 5 of different widths, the electrode length cannot be adjusted, so that some electrodes will not corona treat the film 5 and achieve empty charge. Empty charge not only damages the corona roller 22, but also causes power waste. The problem is achieved by dividing the long strip electrode into a plurality of modular electrode seats 32, and by movably mounting the plurality of modular electrode seats 32 on a mounting seat 35, and connecting the mounting seat 35 to a lifting unit 4, so that when the electrode seat 32 is installed and removed, the entire mounting seat 35 can be lifted out of the ceramic bin 1, so that the electrode seat 32 can be installed and removed conveniently, so that the electrode length can be adjusted accordingly according to the width of the film 5 to be corona treated.

[0022] The embodiment of the invention discloses a high-density ceramic chamber corona machine.

The electrode seat 32 and the slider 34 are arranged in multiple groups, and the electrode seat 32 is connected to the lower position of the slider 34. The slider 34 is slidably connected to the mounting seat 35. The multiple groups of electrode seats 32 can adjust the number of electrode seats 32 on the mounting seat 35 by sliding the slider 34 in and out of the mounting seat 35. By dividing the long electrode into multiple modular electrode seats 32, and movably mounting the multiple modular electrode seats 32 on the mounting seat 35, the electrode length can be adjusted accordingly according to the width of the film 5 to be corona treated, thereby improving the practical flexibility of the high-density ceramic warehouse corona machine, and avoiding the problem of empty electricity caused by the local electrode of the long electrode not coronaing the film 5, which not only protects the corona roller 22 but also saves power. The lifting unit 4 is connected to the installation unit 3, and the lifting unit 4 is used to lift the installation unit 3 out of the ceramic chamber 1 to facilitate the installation and removal of the electrode seat 32. The lifting unit (4) can change the distance between the electrode seat (32) and the film (5), so that different corona effects on the film (5) can be achieved. By connecting the mounting seat 35 to the lifting unit 4, when the electrode seat 32 is installed and removed, the entire mounting seat 35 can be lifted out of the ceramic chamber 1, which facilitates the installation and removal of the electrode seat 32, thereby improving the replacement efficiency of the electrode seat 32.

Before corona treatment, the film 5 is first passed through the bottom of the feed roller 21, the top of the corona roller 22 and the bottom of the discharge roller 23, and then the film 5 is passed through the material port 112 on the bin door 11 to connect it to the external winding device.

[0026] Furthermore, the mounting unit 3 also includes a discharge electrode 31, a first connecting rod 33 and a fastening bolt 36. The discharge electrode 31 is arranged at the bottom of the electrode seat 32. The high voltage current generated by the discharge electrode 31 is used to perform corona treatment on the film. The first connecting rod 33 is used for fixed connection between the electrode seat 32 and the slider 34. The fastening bolt 36 is arranged on one side of the slider 34. The fastening bolt 36 is used to firmly mount the slider 34 on the mounting seat 35. By tightening the fastening bolt 36, the slider 34 can be fixed on the mounting seat 35. By loosening the fastening bolt 36, the slider 34 can be prevented from abutting against the mounting seat 35, thereby allowing the slider 34 to slide in the slide groove 351.

[0027] It is particularly disclosed that a socket 321 is provided on one side of the electrode seat 32, and a slot 322 is opened on the other side of the electrode seat 32. The socket 321 is inserted into the slot 322 of another electrode seat 32. The socket 321 is inserted into the slot 322 and is used for circuit connection of two adjacent electrode seats 32. By inserting the socket 321 into the slot 322, not only the circuit connection of adjacent electrode seats 32 is completed, but also the connection of adjacent electrode seats 32 can be further fixed.

When the card block 3211 slides into the positioning groove 3221, the telescopic spring 3212 is squeezed until the card block 3211 moves into the card slot 3222, and the telescopic spring 3212 squeezes the card block 3211 to reset, thereby making the card block 3211 clamped in the card slot 3222.

[0029] Particularly disclosed, positioning grooves 3221 are provided on both sides of the slot 322, the card block 3211 is slidably connected to the positioning groove 3221, and the card block 3211 abuts against the positioning groove 3221, and a card groove 3222 is provided on the inner side of the positioning groove 3221, and the card block 3211 is carded in the card groove 3222. By providing the positioning grooves 3221, it is not only convenient for the socket 321 to be inserted into the slot 322, but also makes it easier for the card block 3211 to slide out of the card groove 3222, thereby facilitating the socket 321 to slide out of the slot 322; When it is necessary to add an electrode holder 32, the slider 34 is slid from one end of the mounting seat 35 into the sliding groove 351, thereby driving the electrode holder 32 to slide on the bottom of the mounting seat 35 until the adjacent electrode seats 32 contact each other. At this time, the block 3211 at the end of the socket 321 slides into the positioning groove 3221, and the telescopic spring 3212 is squeezed until the block 3211 is slid and clamped in the slot 3222. The telescopic spring 3212 is reset. At this time, the adjacent sliders 34 contact each other, and the fastening bolts 36 are tightened to complete the installation of the electrode holder 32. When it is necessary to remove the electrode holder 32, the fastening bolts 36 are loosened first, and the slider 34 is pulled out from the mounting seat 35. At this time, the block 3211 slides out of the slot 3222 and enters the positioning slot 3221. The telescopic spring 3212 is squeezed until the block 3211 slides out of the positioning slot 3221, and the disassembly of the electrode holder 32 is completed.

[0030] Furthermore, a slide groove 351 is provided on the mounting seat 35, and the slider 34 is slidably connected in the slide groove 351. The slider 34 is slidably connected in the slide groove 351, so that the electrode seat 32 is more convenient to install and remove, thereby improving the installation and removal efficiency of the electrode seat 32.

[0031] Furthermore, the lifting unit 4 includes a support frame 41, a hydraulic cylinder 42, a hydraulic rod 43, a sealing seat 44 and a second connecting rod 45.

The hydraulic cylinder 42 is arranged on the top of the support frame 41, and the top of the hydraulic rod 43 passes through the support frame 41 and is fixedly connected to the output end of the hydraulic cylinder 42. The sealing seat 44 is fixedly connected to the bottom end of the hydraulic rod 43, and the sealing seat 44 is used to seal the opening at the top of the ceramic warehouse 1. The second connecting rod 45 is used to fix the mounting seat 35 and the sealing seat 44. The hydraulic rod 43 is driven up and down by the hydraulic cylinder 42, which can drive the sealing seat 44 and the mounting seat 35 to move up and down, and then drive the electrode seat 32 to move up and down, so as to change the distance between the discharge electrode 31 and the corona roller 22, so as to achieve different corona treatment effects, thereby improving the applicability of the corona machine for high-density ceramic warehouses.

[0032] Working principle: First, the electrode length is adjusted according to the width of the film 5 to be corona treated, and the hydraulic cylinder 42 is opened to drive the hydraulic rod 43 to move upward, thereby driving the sealing seat 44 to move upward, thereby driving the second connecting rod 45 and the mounting seat 35 to move upward, thereby driving the electrode seat 32 to move upward, until the mounting seat 35 and the electrode seat 32 are lifted to the top of the ceramic warehouse 1; Then, when it is necessary to add an electrode holder 32, the slider 34 is slid from one end of the mounting seat 35 into the sliding groove 351, thereby driving the electrode holder 32 to slide on the bottom of the mounting seat 35 until the adjacent electrode holders 32 are in contact with each other. At this time, the block 3211 at the end of the socket 321 slides into the positioning groove 3221, and the telescopic spring 3212 is squeezed until the block 3211 is slid and clamped in the slot 3222, and the telescopic spring 3212 is reset. At this time, the adjacent sliders 34 are in contact, and the fastening bolts 36 are tightened to complete the installation of the electrode holder 32; when it is necessary to remove the electrode holder 32, the fastening bolts 36 are loosened first, and the slider 34 is pulled out of the mounting seat 35.

After the electrode length is adjusted, the mounting seat 35 and the electrode seat 32 are driven into the ceramic warehouse 1 by the hydraulic cylinder 42. At this time, the sealing seat 44 seals the opening, and then the warehouse doors 11 on the front and back of the ceramic warehouse 1 are opened, and the film 5 is passed through the bottom of the feed roller 21, the top of the corona roller 22 and the bottom of the discharge roller 23, and then the film 5 is passed through the material port 112 on the warehouse door 11 to connect it to the external winding device, and finally the power is turned on to perform corona treatment on the film 5.
