Description

Technical Field

[0001] This utility model relates to the field of cleaning devices, specifically to a spray nozzle cleaning and blowing device. Background Technology

[0002] Industrial paint coating equipment is widely used in many different industries, such as the automotive industry. For example, in the automotive industry, robots manipulate paint coaters to apply paint to automobiles and their components.

[0003] In many applications, it is best, and often is, to clean the paint applicator's guard and nozzle between painting operations. Otherwise, paint buildup on the paint applicator can cause drips, uneven paint patterns, and aesthetic defects. When this happens, it often requires complete removal of the paint from the item and repainting the entire item. However, this is a costly and time-consuming process.

[0004] Existing technologies include equipment for cleaning paint applicators in robotic paint coating equipment; however, these existing cleaning devices can only clean the nozzles, and are insufficient for cleaning other types of paint application equipment. Figure 1 The nozzle structure shown has electrode claws on the outside of the nozzle. The electrode claws cannot be dried during cleaning, and the moisture on the electrode claws affects the spraying effect. Summary of the Invention

[0005] To address the shortcomings of the existing technology, this utility model provides a spray nozzle cleaning and blowing device with a simple structure that can clean the electrode claws of the spray nozzle by blowing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A spray nozzle cleaning and blowing device, characterized in that it includes a cover, a mounting platform, a first air blowing ring, and a second air blowing ring, wherein the cover includes an outer cylinder and an inner cylinder arranged coaxially, the bottom of the outer cylinder and the bottom of the inner cylinder are sealed together, the bottom of the inner cylinder is hollow, the upper end of the outer cylinder is higher than the upper end of the inner cylinder, the upper end of the inner cylinder has a first horizontal flange bent inward, the mounting platform is sleeved on the upper part of the inner cylinder, the top surface of the mounting platform has a first placement platform, the lower part of the mounting platform has a second placement platform, the first air blowing ring is disposed on the first placement platform, the second air blowing ring is placed on the second placement platform, and both the first air blowing ring and the second air blowing ring have air blowing ports facing obliquely upward.

[0008] Furthermore, the upper end of the outer cylinder has a second horizontal flange that bends inward.

[0009] Furthermore, the first and second air-blowing rings are metal rings or annular plastic tubes.

[0010] Furthermore, the first and second air-blowing rings are connected to an air source.

[0011] The advantages of this invention include: simple structure, can be externally mounted on paint nozzle cleaning equipment, can clean the electrode claws on the paint nozzle, thereby improving the paint spraying quality of the paint nozzle. Attached Figure Description

[0017] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0018] One such Figure 2-4 The spray nozzle cleaning and purging device shown includes a housing 1, a mounting platform 2, a first air-blowing ring 3, and a second air-blowing ring 4. The housing 1 includes an outer cylinder 11 and an inner cylinder 12 arranged coaxially. A sealed connection between the bottom of the outer cylinder 11 and the bottom of the inner cylinder 12 forms an annular groove for collecting water droplets blown off during purging. The inner bottom of the inner cylinder 12 is hollow, allowing it to be fitted onto the spray nozzle cleaning device. The upper end of the outer cylinder 11 is higher than the upper end of the inner cylinder 12, allowing the outer cylinder 11 to completely accommodate the spray nozzle and electrode claws. The upper end of the inner cylinder 12 has a first horizontal flange 120 bent inwards, which limits the upper part of the cleaning device. The mounting platform 2 is fitted onto the upper part of the inner cylinder 12. The top surface of the mounting platform 2 has a first placement platform 21, which is secured to the first horizontal flange 120 by screws. The lower part of the mounting platform 2 has a second placement platform 22. The first air ring 3 is disposed on the first placement platform 21, and the second air ring 4 is placed on the second placement platform 22. Both the first air ring 3 and the second air ring 4 have air inlets facing obliquely upward, which can blow the electrode claws on the paint spray nozzle.

[0019] The upper end of the outer cylinder 11 has a second horizontal flange 110 that bends inward, which prevents blown-off water vapor from splashing out of the outer cylinder 11.

[0020] For ease of arrangement and processing, in this embodiment, the first air-blowing ring 3 and the second air-blowing ring 4 are metal rings or annular plastic tubes. Air-blowing ports are directly machined onto the metal rings, and the annular plastic tubes are made of plastic air tubing with air-blowing ports connected via tee connectors. The first air-blowing ring 3 and the second air-blowing ring 4 are connected to an air source.

[0021] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
