Technical Field

[0001] This utility model relates to the field of industrial cleaning, and in particular to an adjustable nozzle for a carbon dioxide cleaning machine. Background Technology

[0002] In the field of industrial cleaning, carbon dioxide cleaning technology is widely used for cleaning precision parts such as automotive parts and electronic components due to its advantages such as leaving no residue and not damaging the workpiece. Among them, the adjustable nozzle is the core component, and its adjustment flexibility and functional integration directly affect the cleaning efficiency and quality.

[0003] Patent CN218691974U discloses an adjustable nozzle for an industrial gasoline high-pressure washer, including a detachable filter assembly and an adjustment assembly. The detachable filter assembly includes a gasoline high-pressure washer body, with fixed plates fixedly connected to both sides of the front end of the body. A first spray pipe is fixedly connected to the inner side of the fixed plates corresponding to the front end of the gasoline high-pressure washer body. A placement groove is provided at the top of the first spray pipe. A through hole is provided at the top of the upper fixed plate and penetrates the fixed plate. Sliding grooves are provided at both ends of the upper fixed plate, and tension springs are fixedly connected to the opposite ends of the sliding grooves. In this utility model, the detachable structure facilitates the disassembly and cleaning of the filter plate, saving time, and allows for nozzle angle adjustment, preventing the water pipe from bending at the outlet of the second spray pipe, thereby extending the service life of the water pipe.

[0004] However, the above technical solutions still have the following shortcomings in practical applications: The adjustment dimension of this equipment is limited to two dimensions, which can easily create cleaning blind spots for three-dimensional complex structures such as deep holes and corners; it only has a cleaning function and does not integrate detection and deburring processes, requiring multiple transfers of workpieces, increasing auxiliary time and making it prone to secondary contamination; it lacks a medium homogenization structure, and liquid carbon dioxide is prone to stratification when left to stand, resulting in fluctuations in spray pressure and poor cleaning consistency. Therefore, this utility model proposes an adjustable nozzle for a carbon dioxide cleaning machine. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides, for example Figure 1 - Figure 5An adjustable nozzle for a carbon dioxide cleaning machine is shown, including a housing 1, a protective shell 2 fixedly connected to the upper end of the housing 1, a filter screen provided inside the protective shell 2, a cylinder 3 installed at the upper end of the protective shell 2, an L-shaped rod 4 fixedly connected to the output shaft of the cylinder 3, and an adjustment mechanism 5 for adjusting the spray angle installed inside the protective shell 2.

[0018] In this embodiment, the adjustment mechanism 5 includes a first motor 51 installed on the outside of the L-shaped rod 4. The output shaft of the first motor 51 is fixedly connected to a first rotating shaft 52. The other end of the first rotating shaft 52 is fixedly connected to a fixing block 53. The outside of the fixing block 53 is fixedly connected to a mounting rod 54. The inside of the mounting rod 54 is rotatably connected to a second rotating shaft 55.

[0019] Specifically, the first motor 51 provides the power source for the adjustment mechanism 5 to swing back and forth. Its output shaft is rigidly connected to the fixed block 53 through the first rotating shaft 52. When the first motor 51 is started, it can drive the mounting rod 54 and the second rotating shaft 55 to rotate around the axis of the first rotating shaft 52, thereby realizing the longitudinal angle adjustment of the nozzle body 514 and laying the foundation for three-dimensional coverage cleaning.

[0020] In this embodiment, a first gear 56 is fixedly connected to the outer side of the second rotating shaft 55, a second gear 57 is meshed with the outer side of the first gear 56, the inner side of the second gear 57 is rotatably connected to the mounting rod 54 through the rotating shaft, a second motor 58 is mounted on the outer side of the mounting rod 54, and the output shaft of the second motor 58 is fixedly connected to the second gear 57 through the rotating shaft.

[0021] Specifically, the second motor 58 drives the second gear 57 to rotate, and by utilizing its meshing relationship with the first gear 56, it drives the second rotating shaft 55 to rotate around its own axis, thereby realizing the lateral angle adjustment of the gear ring 59 and the nozzle body 514; the rigid fit of the gear transmission can ensure the accuracy of the angle adjustment and adapt to the cleaning needs of workpieces of different widths.

[0022] In this embodiment, a gear ring 59 is fixedly connected to both ends of the second rotating shaft 55. Slide grooves are provided at both the upper and lower ends of the gear ring 59. A third gear 510 is meshed with the outer side of the gear ring 59. A sliding frame 511 is rotatably connected to the outer side of the third gear 510. The inner side of the sliding frame 511 is slidably connected to the slide groove of the gear ring 59 through a slider.

[0023] Specifically, the toothed ring 59 is fixed to the second rotating shaft 55 at both ends to form a ring track for cleaning; the grooves at its upper and lower ends cooperate with the sliders on the inner side of the sliding frame 511 to provide guidance and limit for the sliding frame 511 and prevent movement deviation; the meshing transmission between the third gear 510 and the toothed ring 59 can convert the rotational power into the circumferential movement of the sliding frame 511 around the toothed ring 59, so as to achieve 360° coverage of the workpiece by the nozzle body 514.

[0024] In this embodiment, the upper end of the sliding frame 511 is fixedly connected to the mounting groove 512, the inner side of the mounting groove 512 is equipped with a steel cylinder 513, the outer side of the steel cylinder 513 is fixedly connected to the nozzle body 514 near the lower end, and a sensor is provided on the outer side of the nozzle body 514.

[0025] Specifically, the mounting groove 512 is used to fix the steel cylinder 513 and ensure its stability when it moves synchronously with the sliding frame 511; the steel cylinder 513 provides liquid carbon dioxide medium to the nozzle body 514, and the nozzle body 514 converts the medium into a high-speed jet to remove dirt; the external sensor can detect the surface cleanliness of the workpiece in real time and provide a signal trigger basis for secondary cleaning.

[0026] In this embodiment, a third motor 515 is installed at the upper end of the cylinder 513. The output shaft of the third motor 515 is fixedly connected to a stirring rod 516. The outer side of the stirring rod 516 is rotatably connected to the cylinder 513. The lower end of the stirring rod 516 is fixedly connected to a third gear 510 through a rotating shaft. The inner side of the third gear 510 is fixedly connected to the outer shell of an electric telescopic rod 517 through a coupling. The output shaft of the electric telescopic rod 517 is fixedly connected to a grinding head 518 through a fixing rod.

[0027] Specifically, the third motor 515 is a dual-function drive source: on one hand, it drives the stirring rod 516 to rotate inside the gas cylinder 513, preventing the liquid carbon dioxide from settling and stratifying, and ensuring stable spray pressure; on the other hand, it drives the third gear 510 to rotate through the shaft at the lower end of the stirring rod 516, providing power for the circumferential motion. The electric telescopic rod 517 can adjust the distance between the grinding head 518 and the workpiece, and together with the circumferential motion, it can achieve the trimming of edge burrs after cleaning, completing multiple processes without additional equipment.

[0028] Working principle: When using this equipment, the automotive parts to be cleaned are placed on the filter screen inside the protective housing 2; the nozzle body 514 is activated to clean the outer side of the parts and the assembly holes; at the same time, the following adjustments are made to achieve full coverage: Start the first motor 51, and its output shaft drives the first rotating shaft 52 to rotate. The first rotating shaft 52 is linked to the mounting rod 54 and the second rotating shaft 55 through the fixed block 53, which in turn drives the toothed ring 59 to swing back and forth around the axis of the first rotating shaft 52, so that the nozzle body 514 covers the longitudinal area of ​​the components. Start the second motor 58, and its output shaft drives the second gear 57 to rotate through the rotating shaft. Since the second gear 57 meshes with the first gear 56, the first gear 56 drives the second rotating shaft 55 and the gear ring 59 to swing left and right around its own axis, so as to achieve cleaning coverage of the horizontal area of ​​the parts. When the third motor 515 is started, its output shaft synchronously drives two components to move: first, the stirring rod 516 rotates inside the steel cylinder 513 to stir the liquid carbon dioxide in the steel cylinder 513 to ensure the uniformity of the medium; second, the stirring rod 516 drives the third gear 510 to rotate through the lower rotating shaft. Because the third gear 510 meshes with the gear ring 59, and the sliding frame 511 slides with the upper and lower grooves of the gear ring 59 through the inner slider, the sliding frame 511 moves along the circumferential trajectory of the gear ring 59, thereby driving the mounting groove 512, the steel cylinder 513 and the nozzle body 514 to make a circular motion, so as to achieve all-round cleaning of the parts without dead angles. During the cleaning process, the cylinder 3 can be extended and retracted, causing its output shaft to drive the adjustment mechanism 5 to move linearly as a whole via the L-shaped rod 4, dynamically adjusting the distance between the nozzle body 514 and the parts to adapt to the cleaning needs of workpieces of different sizes. After the cleaning stage is completed, the nozzle body 514 is closed. The sensor on the outside of the nozzle synchronously detects the cleanliness of the parts surface. If there are uncleaned areas, the nozzle body 514 can be driven by the action of the adjustment mechanism 5 to perform targeted secondary cleaning. After the cleanliness meets the standard, the electric telescopic rod 517 is activated. Its output shaft pushes the grinding head 518 down to fit with the surface of the parts through the fixed rod. Then, the sliding frame 511 is driven by the third motor 515 to continue to rotate. The grinding head 518 is used to deburr and trim the edges of the parts, and finally the entire cleaning process is completed.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
