Description

Technical Field

[0001] The utility model belongs to the technical field of plasma cleaning and relates to a plasma cleaning head. Background Art

[0002] Atmospheric plasma cleaning machine uses compressed air or oxygen as working gas, ionizes gas with high pressure and high frequency to obtain plasma, which is used to treat stains on the surface of materials. It can effectively increase the adhesion of the material surface and improve the effects of pasting, welding, bonding, printing, laminating, etc.

[0003] When the plasma cleaning machine is cleaning the surface of the workpiece, if there are many stains on the surface of the workpiece, the stains will be separated from the workpiece, which will produce dusty exhaust gas. On the one hand, in order to ensure the cleanliness of the working environment, on the other hand, in order to prevent the dust in the air from accumulating and falling back on the surface of the workpiece, it is necessary to collect the exhaust gas and remove the dust in time.

[0004] In the existing plasma cleaning machine, negative pressure ports are actually provided on both sides of the equipment to collect exhaust gas. This solution has certain limitations because the negative pressure ports are far away from the center of the workpiece. Utility Model Content

[0005] The utility model aims to provide a plasma cleaning head to improve the dust removal effect by providing a dust removal head which moves synchronously with the plasma cleaning head.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A plasma cleaning head comprises a plasma nozzle and a dust removal head, wherein the dust removal head is fixed at the nozzle of the plasma nozzle, and the dust removal head is connected to an external negative pressure device to generate negative pressure to collect waste gas.

[0008] Furthermore, the air inlet of the dust removal head is at a higher level than the nozzle of the plasma nozzle.

[0009] Furthermore, the dust removal head is annular and is sleeved on the periphery of the plasma nozzle.

[0010] Furthermore, the dust removal head is provided with two symmetrically distributed negative pressure ports, and the negative pressure ports are connected to external negative pressure equipment.

[0011] Furthermore, it also includes a pressure dividing tube, which is connected to an external negative pressure device. The pressure dividing tube is provided with two pressure dividing branches, and the pressure dividing branches are respectively sealed and connected to the negative pressure port.

[0012] Furthermore, it also includes a mounting plate, the plasma nozzle is connected to the external motion module through the mounting plate, the voltage divider tube and the dust removal head are fixedly connected to the mounting plate through a connecting plate, and the voltage divider tube and the dust removal head move synchronously with the plasma nozzle.

[0013] By applying the technical solution of the utility model, a dust removal head is added to the plasma cleaning head and connected to an external negative pressure device, a more efficient exhaust gas collection and dust removal effect can be achieved. The air inlet level of the dust removal head is higher than the nozzle level of the plasma nozzle, which can avoid the influence of negative pressure on the cleaning effect of the plasma nozzle. In this way, it can be ensured that the plasma cleaning head can fully exert its effect when cleaning the surface of the workpiece and improve the cleaning quality.

[0014] Other features and advantages of the utility model will be described in the following description, and partly become apparent from the description, or understood by implementing the utility model. The purpose and other advantages of the utility model can be realized and obtained by the structures particularly pointed out in the written description and the drawings.

[0022] Reference Figure 1-2 As shown, a plasma cleaning head includes a plasma nozzle 100 and a dust removal head 200, wherein the dust removal head 200 is fixed at the nozzle of the plasma nozzle 100, and the dust removal head 200 is connected to an external negative pressure device to generate negative pressure to collect waste gas. By fixing the dust removal head 200 at the nozzle of the plasma nozzle 100, the waste gas can be directly collected during the cleaning process, and negative pressure is generated by the external negative pressure device, so that the waste gas is efficiently collected and processed. This can effectively reduce the pollution on the surface of the workpiece. The combination design of the plasma nozzle 100 and the dust removal head 200 is simple and can be easily installed in a plasma cleaning machine or other equipment. The connection between the dust removal head 200 and the external negative pressure device is also relatively simple, which is convenient for operation and maintenance. By collecting the waste gas in time, the dust in the waste gas can be prevented from adhering to the surface of the workpiece again, and the stability and consistency of the cleaning effect can be maintained.

[0023] In this embodiment, the air inlet of the dust removal head 200 is higher than the nozzle of the plasma nozzle 100. Since the air inlet of the dust removal head 200 is located at a higher position, relative to the nozzle of the plasma nozzle 100, the influence of negative pressure on the cleaning effect of the plasma nozzle 100 can be avoided. If the air inlet is at a lower position, the negative pressure may interfere with the normal operation of the plasma nozzle 100 and reduce the cleaning effect. By designing the air inlet at a higher position, it can be ensured that the plasma nozzle 100 can fully exert its cleaning function and improve the cleaning quality. The air inlet is higher than the nozzle of the plasma nozzle 100, which means that pollutants and dust detached from the surface of the workpiece will more easily enter the dust removal head 200. This can effectively prevent the dust in the exhaust gas from adhering to the surface of the workpiece again, and avoid the exhaust gas from contaminating the workpiece again. By collecting and treating the exhaust gas in a timely manner, the working environment can be kept clean and the cleaning effect can be improved.

[0024] In this embodiment, the dust removal head 200 is ring-shaped and is sleeved on the periphery of the plasma nozzle 100 .

[0025] Since the dust removal head 200 is sleeved on the periphery of the plasma nozzle 100, an annular structure is formed, which can comprehensively collect the exhaust gas. In this way, no matter which direction the exhaust gas comes from the plasma nozzle 100, the comprehensive collection of the exhaust gas and the improvement of the dust removal effect are ensured. The design of the annular dust removal head 200 allows the negative pressure port 210 to be evenly distributed on the entire annular structure. This ensures that the exhaust gas is evenly absorbed and avoids local blockage or uneven pressure. Uniform absorption of exhaust gas helps to improve the dust removal effect and ensure the cleanliness of the working environment. Since the dust removal head 200 is an annular structure and is sleeved on the periphery of the plasma nozzle 100, installation and maintenance are relatively simple. By fixing the annular dust removal head 200, it can be conveniently installed on a plasma cleaning machine or other equipment, and daily maintenance and cleaning can be carried out.

[0026] In this embodiment, the dust removal head 200 is provided with two symmetrically distributed negative pressure ports 210, and the negative pressure ports 210 are connected to external negative pressure equipment. By designing two symmetrically distributed negative pressure ports 210, the efficiency of exhaust gas collection can be increased. This ensures that the exhaust gas is collected from multiple directions, improves the dust removal effect, and allows the exhaust gas to evenly enter the negative pressure equipment for treatment. Through the symmetrically distributed negative pressure ports 210, local blockage or uneven pressure of the exhaust gas in the dust removal head 200 can be avoided. This ensures balanced absorption of the exhaust gas, improves the dust removal effect, and reduces equipment failures and maintenance.

[0027] In this embodiment, a pressure-dividing tube 300 is also included, and the pressure-dividing tube 300 is connected to an external negative pressure device. The pressure-dividing tube 300 is provided with two pressure-dividing branches 310, and the pressure-dividing branches 310 are respectively sealed and connected to the negative pressure port 210. By introducing the pressure-dividing tube 300, the pipeline between the dust removal head 200 and the negative pressure port 210 can be conveniently connected. As an intermediate connector, the pressure-dividing tube 300 can effectively connect the dust removal head 200 and the external negative pressure device, simplifying the pipeline layout process. The introduction of the pressure-dividing tube 300 can reduce the cost of pipeline layout. Compared with directly connecting the pipeline to the negative pressure port 210 of the dust removal head 200, the introduction of the pressure-dividing tube 300 can provide more flexible pipeline layout options, reduce the length and number of pipelines, and reduce material and installation costs.

[0028] In this embodiment, a mounting plate 400 is also included, through which the plasma spray head 100 is connected to the external motion module, the voltage-dividing tube 300 and the dust removal head 200 are fixedly connected to the mounting plate 400 through the connecting plate 500, and the voltage-dividing tube 300 and the dust removal head 200 move synchronously with the plasma spray head 100. By introducing the mounting plate 400 and the connecting plate 500, the entire design can be simplified. The mounting plate 400 serves as a medium for connecting the plasma spray head 100 and the motion module, and the connecting plate 500 fixes the voltage-dividing tube 300 and the dust removal head 200, connecting them to the mounting plate 400. Such a design makes the entire system more compact and easy to install and maintain. By using the mounting plate 400 and the connecting plate 500, the versatility of the system can be improved. The design of the mounting plate 400 and the connecting plate 500 can adapt to plasma spray heads 100, voltage-dividing tubes 300 and dust removal heads 200 of different models and specifications, making them easier to replace and upgrade. This allows for easy adaptation to different work requirements and equipment configurations.
