Description

Technical Field

[0001] This invention relates to the field of corona dust removal, and more particularly to a corona dust removal device and a corona machine. Background Technology

[0002] When processing thin film materials, the corona machine needs to ensure that the surface of the thin film material is as clean and dust-free as possible.

[0003] In the prior art, CN215825948U, "High-efficiency thin film surface corona treatment machine," discloses a corona treatment machine. Several through holes are opened on the surface of the dust-removing rubber rollers in the dust-removing roller assembly. The dust-removing rubber rollers in the assembly are hollow rollers, and one end of each roller is connected to a vacuum pump. The dust-removing roller assembly simultaneously attracts and sucks dust, resulting in better dust removal.

[0004] However, the air pump disclosed in CN215825948U has limited adsorption capacity for dust due to its distance from the membrane, and cannot effectively remove dust from the membrane surface. Furthermore, since corona sparks may generate fine particles during membrane processing, these particles, as dust on the membrane, also need to be treated. Summary of the Invention

[0005] To address the problems existing in the prior art, the present invention aims to provide a dust removal device and a corona machine for corona treatment, thereby achieving effective dust removal during the corona treatment process.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] A dust removal device for a corona machine includes a first suction pipe with a first suction hole facing the discharge electrode of the corona machine. A second suction pipe, separable from the first suction pipe, is located inside the first suction pipe and can move along the axis of the first suction pipe. The second suction pipe has a second suction hole, which is configured to cooperate with the first suction hole. Dust flows sequentially through the discharge electrode of the corona machine, the first suction hole, and the second suction hole before being deposited in the second suction pipe.

[0008] Furthermore, it includes a dust collection hood, the opening of which is oriented toward the corona machine's corona roller, the corona machine's discharge electrode being disposed within the dust collection hood, and the dust collection hood being connected to the first dust collection pipe.

[0009] Furthermore, there are several second suction holes, which are staggered and arranged sequentially along the axis of the second suction pipe.

[0010] Furthermore, a suction device is connected to one side of the second suction pipe, and the distribution density of each of the second suction holes gradually increases in the direction away from the suction device.

[0011] Furthermore, one end of the second suction pipe is provided with an opening groove, and the first suction pipe is provided with a limiting post that cooperates with the opening groove.

[0012] Furthermore, a handle is provided at the other end of the second suction pipe, and the handle is located inside the second suction pipe.

[0013] A corona machine includes any of the above-described corona machine dust removal devices, and the corona machine dust removal device is further provided with a feeding dust removal device on the side facing the inlet of the corona machine.

[0014] Furthermore, the feeding dust removal device includes a dust removal roller, a dust suction head, and a driving mechanism. The dust suction head has a first position and a second position, and the driving mechanism drives the dust suction head to switch between the first position and the second position. When the dust suction head is in the first position, the dust suction head is close to the dust removal roller; when the dust suction head is in the second position, the dust suction head is away from the dust removal roller.

[0015] Furthermore, the driving mechanism is a cylinder.

[0016] Furthermore, the vacuum head includes two vacuum strips arranged parallel to each other.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: by setting the first dust suction hole, the dust generated during the corona discharge process is effectively sucked into the first dust suction pipe through the discharge electrode of the corona machine; by setting the second dust suction pipe in the first dust suction pipe and by setting the second dust suction hole, the dust generated during the corona discharge process is effectively sucked into the second dust suction pipe; the second dust suction pipe can move along the axial direction of the first dust suction pipe, so as to pull the second dust suction pipe out from the first dust suction pipe, which is convenient for cleaning the dust accumulated in the second dust suction pipe.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0031] like Figures 1 to 2 As shown, this invention discloses a dust removal device for a corona discharge machine, used to adsorb dust generated during the corona discharge process of a corona discharge machine for treating thin film materials. The dust removal device includes a first suction pipe 1 with a first suction hole 2 facing the discharge electrode 3 of the corona discharge machine. A second suction pipe 4, detachable from the first suction pipe 1, is provided inside the first suction pipe 1. The second suction pipe 4 can move along the axis of the first suction pipe 1, meaning it can be pulled out or inserted into the first suction pipe 1 along its axis. A second suction hole 5 is provided on the second suction pipe 4, and the first suction hole 2 and the second suction hole 5 are configured to cooperate with each other. In this embodiment, there are multiple first suction holes 2 and multiple second suction holes 5, and the number of first suction holes 2 and multiple second suction holes 5 are the same. When the second suction pipe 4 is inserted into the first suction pipe 1 and the second suction pipe 4 is installed in place, each of the first suction holes 2 and each of the second suction holes 5 corresponds one-to-one. In this invention, an air suction device is connected to one side of the second suction pipe 4. After the air suction device is activated, it begins to suction air from the corona discharge electrode 3. During the corona operation, dust on the film flows sequentially through the corona discharge electrode 3, the first suction hole 2, and the second suction hole 5, and then deposits in the second suction pipe 4. When a large amount of dust accumulates in the second suction pipe 4, the second suction pipe 4 can be pulled out from the first suction pipe 1 to clean the dust. This invention effectively draws dust generated during the corona discharge process into the first dust collection pipe 1 through the corona discharge electrode 3 by setting the first dust collection hole 2. By setting the second dust collection pipe 4 in the first dust collection pipe 1 and by setting the second dust collection hole 5, the dust generated during the corona discharge process is effectively drawn into the second dust collection pipe 4. The second dust collection pipe 4 can move along the axial direction of the first dust collection pipe 1, so that the second dust collection pipe 4 can be pulled out from the first dust collection pipe 1, which is convenient for cleaning the dust accumulated in the second dust collection pipe 4.

[0032] like Figures 1 to 3 As shown, the dust removal device for the corona machine of the present invention includes a dust suction hood 6, which is strip-shaped and has an opening on one side. The opening of the dust suction hood 6 faces the corona roller 7 of the corona machine, and the dust suction hood 6 is connected to the first dust suction pipe 1. The cross-section of the dust suction hood 6 along its length is approximately triangular, meaning the opening area of ​​the dust suction hood 6 gradually decreases in the direction away from the opening. The first dust suction pipe 1 is located away from the opening of the dust suction hood 6. The corona machine discharge electrode 3 is disposed in the dust suction hood 6 and is connected to a power supply device 8. The power supply device 8 is columnar and penetrates the dust suction hood 6. The first dust suction pipe 1 and the dust suction hood 6 are connected through the first dust suction hole 2. Ideally, the axis of the second suction hole 5 passes through the axis of the corona roller 7 of the corona machine. In this case, the direction of the corona spark is the same as the direction of dust adsorption, resulting in the best adsorption effect. However, in actual use, to facilitate power supply to the discharge electrode 3 of the corona machine, the axis of the power supply device 8 passes through the axis of the corona roller 7. Therefore, the second suction hole 5 needs to be positioned as close as possible to the discharge electrode 3 of the corona machine without interfering with it. This invention, through the arrangement of the suction hood 6, ensures that the dust generated during the corona process is mainly concentrated inside the suction hood 6, facilitating dust adsorption.

[0033] like Figure 4 As shown, in this embodiment, because the axial direction of the second dust suction hole 5 does not pass through the axis of the corona roller 7 of the corona machine during corona treatment, there is room for improvement in dust adsorption effect. Therefore, taking the second dust suction pipe 4 as an example, the second dust suction pipe 4 is a cylindrical straight pipe, with several second dust suction holes 5, which are staggered and arranged sequentially along the axial direction of the second dust suction pipe 4. Figure 5 As shown, the opening of the dust suction hood 6 may be provided with an arc-shaped surface 9 for guiding airflow. Because the second suction holes 5 are staggered and the pipe surface of the second suction pipe 4 is arc-shaped, the airflow direction of each second suction hole 5 is different. Some dust can be directly sucked into the second suction pipe 4 without being guided by the arc-shaped surface 9, while some dust cannot be directly sucked into the second suction pipe 4. However, this part of the dust is guided into the second suction pipe 4 through the second suction holes 5 by the arc-shaped surface 9. This invention improves the dust adsorption effect when the axis of the second suction hole 5 cannot pass through the axis of the corona roller 7 of the corona machine by staggering the second suction holes 5 and using the arc-shaped surface 9.

[0034] like Figure 4 As shown, in this embodiment, because the suction force at the second suction pipe 4, which is farther from the suction device, is smaller than that at the second suction pipe 4, which is closer to the suction device, the distribution density of each of the second suction holes 5 gradually increases towards the direction away from the suction device. This invention increases the suction force at the second suction pipe 4, which is farther from the suction device, by setting different densities for the second suction holes 5.

[0035] like Figure 3 and Figure 4 As shown, in this embodiment, the first end of the second suction pipe 4 is provided with an opening groove 10, and the first suction pipe 1 is provided with a limiting post 11 that cooperates with the opening groove 10. When it is necessary to clean the dust in the second suction pipe 4, the second suction pipe 4 is pulled out from the first suction pipe 1; after cleaning the dust in the second suction pipe 4, the opening groove 10 is aligned with the limiting post 11, and the second suction pipe 4 is pushed into the first suction pipe 1. When the limiting post 11 enters the opening groove 10, the second suction pipe 4 is pushed in. At this time, each of the second suction holes 5 corresponds one-to-one with each of the first suction holes 2. The present invention, through the setting of the opening groove 10 and the limiting post 11, realizes the positioning of the second suction pipe 4 in the first suction pipe 1, which facilitates the alignment of the second suction holes 5 and the first suction holes 2.

[0036] like Figure 4 As shown, a handle 12 is provided at the second end of the second suction pipe 4, and the handle 12 is disposed inside the second suction pipe 4. When it is necessary to pull the second suction pipe 4 out of the first suction pipe 1, the handle 12 can be pulled. Because the handle 12 is disposed inside the second suction pipe 4, when the second suction pipe 4 is located inside the first suction pipe 1 and the corona machine is working, a flat cover plate can be used to cover the second end of the second suction pipe 4. The present invention facilitates the removal of the second suction pipe 4 by providing the handle 12, and the arrangement of the handle 12 inside the second suction pipe 4, along with the aesthetically pleasing appearance when the flat cover plate covers the second end of the second suction pipe 4, results in a more convenient removal of the second suction pipe 4.

[0037] This invention also provides a corona treatment machine for processing thin film materials. The corona treatment machine includes the aforementioned corona treatment dust removal device, and a feeding dust removal device is further provided on the side of the corona treatment machine facing the inlet direction. Through the inclusion of the feeding dust removal device, this invention removes dust from the film before the corona treatment process, preventing dust from entering the corona treatment process and affecting the quality of the corona treatment.

[0038] like Figure 6 and Figure 7 As shown, the feeding dust removal device includes a dust removal roller 13, a dust suction head 14, and a driving mechanism, wherein the driving mechanism is a cylinder 15. To facilitate dust adsorption, the dust suction head 14 includes two parallel dust suction strips 16, forming a dust suction channel between them. In this embodiment, the dust suction channel can be relatively narrow; for example, the distance between the two dust suction strips 16 can be 0.5 cm to 1 cm. Therefore, the gas flow rate in the dust suction channel is relatively high, resulting in a better dust suction effect.

[0039] In this embodiment, the suction head 14 is strip-shaped and has a first position and a second position. The cylinder 15 drives the suction head 14 to switch between the first position and the second position. When the suction head 14 is in the first position, it is close to the dust removal roller 13. Specifically, the suction strip 16 is close to the dust removal roller 13, and the suction direction of the suction channel passes through the axis of the dust removal roller 13. At this time, the suction head 14 can work to perform suction operations. When the suction head 14 is in the second position, it is away from the dust removal roller 13. Specifically, the suction strip 16 is away from the dust removal roller 13. At this time, the suction head 14 is not working, and workshop workers can manually pass the film through the dust removal roller 13. The present invention facilitates the switching of the suction head 14 between the first and second positions through the setting of the driving mechanism; and improves the suction effect through the setting of the suction strip 16.

[0040] like Figure 6 and Figure 8 As shown, the overall structure of the corona machine of the present invention is as follows:

[0041] The corona treatment machine also includes two parallel wall panels 17. The first dust suction pipe 1, the second dust suction pipe 4, the corona treatment roller 7, the dust removal roller 13, and the dust suction head 14 are all fixed at both ends on the parallel wall panels 17. The corona treatment machine also includes a first guide roller 18 and a second guide roller 19. The first guide roller 18 is located on the side of the feeding dust removal device facing the corona treatment machine inlet, and the second guide roller 19 is located on the side of the corona treatment dust removal device facing the corona treatment machine outlet. The first guide roller 18 and the second guide roller 19 are used to change the direction of the film, increase the contact area of ​​the film on the corona treatment roller 7, thereby increasing the corona treatment area and tensioning the film. The ends of the first guide roller 18 and the second guide roller 19 are also fixed on the parallel wall panels 17, and the axes of the corona treatment roller 7, the dust removal roller 13, the first guide roller 18, and the second guide roller 19 are all in the same straight line direction.

[0042] like Figure 6 As shown, the working steps of the corona machine of the present invention are as follows:

[0043] S1, drive the cylinder 15 to position the suction head 14 in the second position, and move the suction strip 16 away from the dust removal roller 13.

[0044] S2, manually pass the film sequentially through the first guide roller 18, the dust removal roller 13, the corona machine corona roller 7 and the second guide roller 19.

[0045] S3, drive the cylinder 15 to position the suction head 14 in the first position, and the suction strip 16 is close to the dust removal roller 13.

[0046] S4, the suction device and the dust suction head 14 work to suction the film on the dust removal roller 13 and the film on the corona machine corona roller 7, respectively.

[0047] S5. After the corona machine completes the corona operation, turn off the corona machine, remove the second suction pipe 4, and clean the dust from the second suction pipe 4.

[0048] In summary, this invention effectively draws dust generated during the corona treatment process into the first suction pipe 1 via the corona discharge electrode 3 by setting the first suction hole 2. By setting the second suction pipe 4 within the first suction pipe 1 and by using the second suction holes 5, the dust generated during the corona treatment process is effectively drawn into the second suction pipe 4. The second suction pipe 4 can move along the axis of the first suction pipe 1, allowing it to be pulled out of the first suction pipe 1 for easy cleaning of dust accumulated in the second suction pipe 4. The suction hood 6 ensures that dust generated during the corona treatment process is mainly concentrated within it, facilitating dust adsorption. By staggering the second suction holes 5 and using the arc-shaped surface 9, the dust adsorption effect is improved when the axis of the second suction holes 5 cannot pass through the axis of the corona roller 7. By setting different densities for the second suction holes 5, the suction force is increased at the second suction pipe 4, which is farther from the suction device. The opening slot 10 and the limiting post 11 enable the second suction pipe 4 to be positioned within the first suction pipe 1, facilitating the alignment of the second suction hole 5 with the first suction hole 2. The handle 12 facilitates the removal of the second suction pipe 4, and its placement within the second suction pipe 4, along with the aesthetically pleasing appearance when the flat cover plate conceals its second end, contributes to a cleaner look. The feeding dust removal device removes dust from the film before corona treatment, preventing dust from entering the corona treatment process and affecting its quality. The drive mechanism facilitates switching between the first and second suction heads. The suction strip 16 enhances the suction effect.

[0049] It should be emphasized that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention shall still fall within the scope of the technical solution of the present invention.
