Technical Field

[0001] The utility model relates to the technical field of plasma cleaning, in particular to a double-head plasma cleaning machine. Background Art

[0002] Plasma, also known as the plasma state. The matter in the plasma state has properties similar to those of the gaseous state, such as good fluidity and diffusivity. However, since the basic constituent particles of the plasma are ions and electrons, it also has many properties different from those of the gaseous state, such as good electrical conductivity and thermal conductivity. In particular, according to scientific calculations, the specific heat capacity of the plasma is proportional to the temperature, and the specific heat capacity of the plasma at high temperatures is often hundreds of times that of the gas. Therefore, the application of the plasma is very extensive, and it has very important application value in aspects such as our daily life, industry, agriculture, environmental protection, military, aerospace, energy, and celestial bodies.

[0003] Before the surface treatment of the workpiece, in order to obtain good adhesion of the material surface, using plasma for surface cleaning treatment is a common treatment method. Plasma is an ionized gaseous substance composed of positive and negative ions generated after the atomic group after some electrons are deprived is ionized, and it is mainly sprayed onto the surface of the workpiece by the nozzle of the plasma treatment device to achieve the treatment purpose.

[0004] The existing plasma cleaning machine only includes one cleaning nozzle, and the cleaning range is small. When cleaning products with a large cleaning area, it takes a lot of time, which results in low cleaning efficiency of the products. Therefore, it is necessary to provide a double-head plasma cleaning machine to solve the above problems. Content of the Utility Model

Gas enters the total air inlet channel opened inside the mounting seat connecting shaft through the air pipe joint, and flows into the corresponding plasma cleaning nozzles through two air inlet sub-channels connected to the tail of the total air inlet channel.

[0007] Further, the driving assembly includes a driving member and a transmission assembly. The transmission assembly includes a driving pulley and a driven pulley. The driving end of the driving member is connected to the driving pulley, and the driven pulley is fixedly connected to the mounting seat connecting shaft. The driving pulley and the driven pulley are connected by belt drive. When the driving member drives the driving pulley to rotate, the driven pulley can also drive the entire mounting connecting shaft to rotate. One end of the mounting connecting shaft is detachably connected to the shampooing mounting seat, so that the plasma cleaning head on the cleaning head mounting seat can also rotate during cleaning, thereby expanding the cleaning range.

[0008] Further, the two plasma cleaning heads are inclined towards the center line in the horizontal direction away from the cleaning head mounting seat. The two inclined plasma cleaning heads can expand the cleaning range during the rotating cleaning process. Compared with setting only one plasma cleaning head, it can not only expand the cleaning range but also improve the cleaning efficiency of the product to be cleaned.

[0009] Further, the total intake air passage and the intake air sub-passages are arranged in a Y shape. The two intake air sub-passages are respectively communicated with the interiors of the two plasma cleaning heads. The clean gas enters the plasma cleaning head and is ionized into plasma gas, and finally is ejected from the nozzle of the plasma cleaning head to clean the product to be cleaned.

[0010] Further, it further includes a mounting housing. The connecting shaft assembly is located inside the mounting housing, and the mounting seat connecting shaft is connected to the front plate of the mounting housing and the connecting shaft support plate vertically arranged inside the mounting housing through two bearings respectively.

A rotational speed sensor and a carbon brush two are arranged on the connecting shaft support plate, and the rotational speed sensor corresponds to the position of the arc-shaped groove on the test disk. The test disk and the rotational speed sensor cooperate with each other. The rotational speed sensor calculates the rotational speed of the plasma cleaning head during rotational cleaning according to the number of arc-shaped grooves at the corresponding positions on the test disk during rotation, which is convenient for the staff to check the working condition of the plasma cleaning head in real time, and thus can timely detect whether the driving member fails.

[0011] Further, it further includes a transmission mounting plate and a carbon brush mounting seat covering the high-voltage wire connecting shaft. The transmission assembly is located inside the transmission mounting plate. The top of the carbon brush mounting seat is used to support the horizontally placed driving member. Two carbon brushes one corresponding to the position of the high-voltage wire connecting shaft are arranged on the side of the carbon brush mounting seat away from the plasma cleaning head. The carbon brush mounting seat can, on the one hand, support the setting of the carbon brush one corresponding to the position of the high-voltage wire connecting shaft, and on the other hand, can support the horizontally placed driving member. The carbon brush one is used to connect the high-voltage wire.

[0012] Furthermore, a protective cover with a hollow interior is provided around the surface of the cleaning head mounting seat, and the protective cover extends along the length direction of the plasma cleaning head. It can effectively protect the plasma cleaning head, preventing some of the dust on the product from adhering to the surface of the plasma cleaning head during product cleaning, which can reduce the workload of the user and eliminate the need for frequent cleaning of the plasma cleaning head.

[0013] Advantages of the present utility model:

Specific embodiments

[0021] The following describes in detail the preferred embodiments of the present utility model with reference to the accompanying drawings, so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making the protection scope of the present utility model more clearly defined.

[0022] See the attached Figures 1 to 5As shown in the figure, a double-headed plasma cleaner in this embodiment includes two groups of plasma cleaning heads 3, a driving component 5 for driving the plasma cleaning heads 3 to rotate, and a connecting shaft component 7. The two groups of plasma cleaning heads 3 are mounted on the cleaning head mounting seat 4. By setting two groups of plasma cleaning heads 3, when the cleaning head mounting seat 4 rotates, the spraying range of the plasma gas can be effectively expanded, and thus the cleaning range of the product to be cleaned can be expanded.

[0023] The connecting shaft component 7 includes a horizontally arranged mounting seat connecting shaft 71 and a high-voltage wire connecting shaft 72 sleeved thereon to realize the installation of the high-voltage wire. One end of the high-voltage wire is arranged inside the plasma cleaning head 3, and the other end is arranged on the high-voltage wire connecting shaft 72. The high-voltage wire connecting shaft 72 can rotate synchronously with the plasma cleaning head 3 when the plasma cleaning head 3 rotates, thus avoiding the twisting phenomenon of the high-voltage wire and realizing the reasonable arrangement of the high-voltage wire.

[0024] One end of the mounting seat connecting shaft 71 is detachably connected to the cleaning head mounting seat 4, which is convenient for the user to disassemble or replace different plasma cleaning heads 3.

[0025] In some embodiments, one end of the mounting seat connecting shaft 71 and the cleaning head mounting seat 4 can be connected by screws.

[0026] The other end is provided with an air pipe joint 9. Gas enters the total intake channel 14 opened inside the mounting seat connecting shaft 71 through the air pipe joint 9 and flows into the corresponding plasma cleaning heads 3 through two intake sub-channels 15 connected to the tail of the total intake channel 14. The two intake sub-channels 15 divide the gas in the total intake channel 14, so that the evenly divided gas flows into the two plasma cleaning heads 3 respectively for ionization.

[0027] The driving component 5 includes a driving member and a transmission component 52. The transmission component 52 includes a driving pulley 521 and a driven pulley 522. The driving end of the driving member is connected to the driving pulley 521, and the driven pulley 522 is fixedly connected to the mounting seat connecting shaft 71. The driving pulley 521 and the driven pulley 522 are connected by a belt drive. When the driving member drives the driving pulley 521 to rotate, the driven pulley 522 can also drive the whole mounting connecting shaft to rotate. One end of the mounting connecting shaft is detachably connected to the equalizing head mounting seat, and thus the plasma cleaning heads 3 on the cleaning head mounting seat 4 can also rotate during cleaning, thereby expanding the cleaning range.

[0028] In some embodiments, the driving member is a driving motor 51. However, it should be noted that it is not limited that the driving member can only be the driving motor 51, as long as it can drive the driving pulley 521 to rotate, such as a dividing plate, etc.

[0029] The two groups of the plasma cleaning heads 3 are inclinedly arranged towards the horizontal center line away from the cleaning head mounting seat 4. The two inclinedly arranged plasma cleaning heads 3 can expand the cleaning range during the rotational cleaning process. Compared with the case of arranging only one plasma cleaning head 3, while expanding the cleaning range, the cleaning efficiency of the product to be cleaned can also be improved.

[0030] In some embodiments, the two groups of plasma cleaning heads 3 are symmetrically arranged along the horizontal center line of the cleaning head mounting seat 4.

[0031] The total intake air channel 14 and the intake air sub-channels 15 are arranged in a Y shape. The two intake air sub-channels 15 are respectively internally communicated with the two plasma cleaning heads 3. The clean gas enters the plasma cleaning heads 3 and is ionized into plasma gas, and finally is ejected from the nozzles of the plasma cleaning heads 3 to clean the product to be cleaned.

[0032] By arranging it in a Y shape, the gas in the total intake air channel 14 is evenly split, ensuring that there is uniform clean gas entering the two plasma cleaning heads 3.

[0033] It further includes a mounting housing 1. The connecting shaft assembly 7 is located inside the mounting housing 1. The mounting seat connecting shaft 71 is connected to the front plate of the mounting housing 1 and the connecting shaft support plate 8 vertically arranged inside the mounting housing 1 through two bearings respectively. One end of the mounting seat connecting shaft 71 close to the air pipe joint 9 is provided with a test disk 10 whose one side abuts against the test disk 10. A rotational speed sensor 11 and a second carbon brush 13 are arranged on the connecting shaft support plate 8. The rotational speed sensor 11 corresponds to the position of the arc-shaped groove 101 on the test disk 10. The test disk 10 and the rotational speed sensor 11 cooperate with each other. The rotational speed sensor 11 calculates the rotational speed of the plasma cleaning head 3 during rotational cleaning according to the number of times of the arc-shaped groove 101 at the corresponding position on the test disk 10 during rotation, which is convenient for the staff to check the working condition of the plasma cleaning head 3 in real time, and then can timely detect whether the driving part fails. The second carbon brush 13 is used for grounding to avoid abnormalities during the discharge process.

[0034] It further includes a transmission mounting plate 6 and a carbon brush mounting seat 16 covering the high-voltage wire connecting shaft 72. The transmission assembly 52 is located inside the transmission mounting plate 6. The top of the carbon brush mounting seat 16 is used to support the horizontally placed driving part. Two first carbon brushes 12 corresponding to the position of the high-voltage wire connecting shaft 72 are arranged on one side of the carbon brush mounting seat 16 away from the plasma cleaning head 3. The carbon brush mounting seat 16 can, on the one hand, support the arrangement of the first carbon brushes 12 corresponding to the position of the high-voltage wire connecting shaft 72, and on the other hand, can support the horizontally placed driving part. The first carbon brushes 12 are used to connect the high-voltage wires.

[0035] The surface of the cleaning head mounting seat 4 is surrounded by a protective cover 2 with a hollow interior, and the protective cover 2 extends along the length direction of the plasma cleaning head 3. It can effectively protect the plasma cleaning head 3, preventing some of the dust on the product from adhering to the surface of the plasma cleaning head 3 during product cleaning, which can reduce the workload of the user and eliminate the need to frequently clean the plasma cleaning head 3.

[0036] The above embodiments are only for illustrating the technical concept and features of the present invention, and their purpose is to enable those familiar with this technology to understand the content of the present invention and implement it. However, the protection scope of the present invention cannot be limited thereby.
