Description

Technical Field

[0001] The present invention relates to a cleaning machine, and more particularly to a multi-nozzle mechanical switching high-pressure cleaning machine. Background Art

[0002] Traditional high-pressure cleaners are typically equipped with a single nozzle or multiple nozzles that require manual replacement to meet the needs of different cleaning scenarios, such as large-area washing, delicate decontamination, or high-pressure cutting. When a nozzle needs to be replaced, the operator must manually remove and install the new nozzle, which is not only time-consuming and labor-intensive, but may also cause interface wear or seal failure due to frequent operation. Furthermore, different nozzles have different spray angles, flow rates, and pressure requirements, but traditional cleaning machines usually only provide fixed pressure output or require manual adjustment. If the pressure does not match the nozzle, it can lead to poor cleaning results (due to insufficient pressure) or equipment overload (due to excessive pressure). Summary of the Invention

DETAILED DESCRIPTION

[0026] The present invention will be further described in detail below with reference to the accompanying drawings.

[0027] like Figures 1 to 9 As shown, the structure and function of the multi-nozzle mechanical switching high-pressure cleaning machine are described in detail below;

[0028] A multi-nozzle mechanical switching high-pressure cleaning machine includes two device brackets 11, two connecting brackets 13 are fixedly connected between the two device brackets 11, and a sliding seat II 31 is slidably connected to each of the two device brackets 11. Both sliding seats II 31 are fixedly connected to a swing motor 32. The output shafts of the two swing motors 32 are fixedly connected to a swing bracket 33. The swing bracket 33 is fixedly connected to a cleaning mechanism 4. The cleaning mechanism 4 is provided with a head changing mechanism 5. The two connecting brackets 13 are slidably connected to a clamping mechanism 2.

[0029] When using, such as Figure 1As shown, the parts to be cleaned are placed between the two clamping mechanisms 2, and the parts to be cleaned are clamped by the two clamping mechanisms 2. Then, by starting the swing motor 32, which is preferably a servo motor, the output shaft of the swing motor 32 drives the swing bracket 33 to move, and the swing bracket 33 drives the cleaning mechanism 4 to move, thereby adjusting the angle of the cleaning mechanism 4 so that the cleaning mechanism 4 can clean the parts from different angles. The cleaning mechanism 4 cleans the parts through the head changing mechanism 5, and the head changing mechanism 5 is equipped with multiple nozzles 57 of different models. The positions of the multiple nozzles 57 are replaced by the head-changing mechanism 5, so that the designated nozzle 57 moves to the cleaning position, and the parts are cleaned by the nozzle 57. Due to the different models of the nozzles 57, the nozzles 57 will spray water columns of different thicknesses. Under the condition that the water output of the cleaning mechanism 4 is constant, in order to control the impact force of the water column sprayed by the nozzle 57 due to the change of the nozzle model, the pressure regulating pipe 55 provided in the head-changing mechanism 5 is used to dynamically adjust the impact force of the water column sprayed by the nozzle 57. This realizes the replacement of different nozzles according to usage needs and automatically adjusts the pressure sprayed by the nozzles.

[0030] like Figure 2 As shown, the device bracket 11 is rotatably connected to a screw rod I 12, and the connecting bracket 13 is rotatably connected to a screw rod II 14;

[0031] The device bracket 11 is fixedly connected to a power mechanism I for driving a screw rod I 12 for rotation, and the connecting bracket 13 is fixedly connected to a power mechanism II for driving a screw rod II 14 for rotation;

[0032] The sliding seat II 31 is connected to the screw rod I 12 via a thread;

[0033] During use, when it is necessary to adjust the cleaning position of the cleaning mechanism 4 and the position of the parts, the power mechanism I is started. The power mechanism I is preferably a servo motor, and the output shaft of the power mechanism I starts to rotate. The output shaft of the power mechanism I drives the screw rod I 12 to rotate. When the screw rod I 12 rotates, it drives the sliding seat II 31 to move through the thread, so that the sliding seat II 31 slides on the device bracket 11, thereby adjusting the position of the sliding seat II 31. The sliding seat II 31 drives the cleaning mechanism 4 to move, thereby adjusting the cleaning position of the cleaning mechanism 4 for the parts;

[0034] Start the power mechanism II, which is preferably a servo motor. The output shaft of the power mechanism II drives the screw rod II 14 to rotate. During the rotation of the screw rod II 14, the clamping mechanism 2 is driven by the thread to move laterally, thereby adjusting the lateral position of the clamping mechanism 2. The clamping mechanism 2 drives the parts to move, thereby adjusting the lateral position of the parts, and then adjusting the cleaning position of the parts, thereby achieving comprehensive cleaning of the parts.

[0035] like Figure 3 As shown, the clamping process of the parts is described in detail below;

[0036] The clamping mechanism 2 includes a sliding seat 21, which is slidably connected to the connecting bracket 13. The sliding seat 21 is connected to the screw rod II 14 by a thread. The sliding seat 21 is fixedly connected to the telescopic mechanism I 22. The telescopic end of the telescopic mechanism I 22 is fixedly connected to a rotating motor 23. The output shaft of the rotating motor 23 is fixedly connected to the clamping bracket 24. The clamping bracket 24 is rotatably connected to two clamping wheels 25. A clamping belt 26 is transmission-connected between the two clamping wheels 25.

[0037] The clamping bracket 24 is fixedly connected to a power mechanism III for driving the clamping wheel 25 to rotate;

[0038] When in use, the part to be cleaned is placed between the two clamping belts 26, and the telescopic mechanism I 22 is started. The telescopic mechanism I 22 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism I 22 drives the rotary motor 23 to move, and the rotary motor 23 drives the clamping bracket 24 to move. The clamping bracket 24 drives the clamping wheel 25 to move, and the clamping wheel 25 drives the clamping belt 26 to move, so that the clamping belt 26 approaches the part, and then the part is clamped by the mutual approach of the two clamping belts 26.

[0039] Furthermore, the rotating motor 23 is started. The rotating motor 23 is preferably a servo motor. The output shaft of the rotating motor 23 drives the clamping bracket 24 to rotate. The clamping bracket 24 drives the clamping belt 26 to rotate. The clamping belt 26 drives the parts to rotate, thereby adjusting the angle of the parts to achieve comprehensive cleaning of the parts.

[0040] Furthermore, since there is a certain contact surface between the clamping belt 26 and the part, in order to achieve comprehensive cleaning of the part, the power mechanism III is started. The power mechanism III is preferably a servo motor. The output shaft of the power mechanism III drives the clamping wheel 25 to rotate, and the clamping wheel 25 drives the clamping belt 26 to move, so that the clamping belt 26 pushes the part to move, thereby adjusting the contact position between the part and the clamping belt 26 to achieve comprehensive cleaning of the part.

[0041] Furthermore, the structure and function of the cleaning mechanism 4 are described in detail below;

[0042] like Figure 5 As shown, the cleaning mechanism 4 includes a support pipe 41, a support cylinder 42 is fixedly connected to the middle of the support pipe 41, the support cylinder 42 and the support pipe 41 are in communication, the support pipe 41 is fixedly connected between the two swing brackets 33, a liquid outlet 48 is provided at the lower end of the support cylinder 42, and two connecting pipes 44 are fixedly connected to the support pipe 41;

[0043] One connecting pipe 44 is used to connect to the water inlet pipe, and the other connecting pipe 44 is used to connect to the water outlet pipe, so that the cleaning water enters the support pipe 41 through the connecting pipe 44, enters the support tube 42 through the support pipe 41, and a part of the cleaning water is discharged through the liquid outlet 48 provided on the support tube 42, and the other part is discharged through the connecting pipe 44;

[0044] Furthermore, in order to control the outlet pressure of the liquid outlet 48, two flow regulating plates 47 are fixedly connected to the support pipe 41, a telescopic mechanism II 45 is fixedly connected to the swing bracket 33, and a flow regulating ball 46 is fixedly connected to the telescopic end of the telescopic mechanism II 45, and the flow regulating ball 46 can be pressed against the flow regulating plate 47;

[0045] Start the telescopic mechanism II 45. The telescopic mechanism II 45 can be a hydraulic cylinder or an electric push rod. The telescopic end of the telescopic mechanism II 45 drives the flow regulating ball 46 to move, adjusts the distance between the flow regulating ball 46 and the flow regulating plate 47, and the flow regulating plate 47 is provided with an arc hole, thereby adjusting the size of the flow passing through the flow regulating ball 46 and the flow regulating plate 47, thereby controlling the flow in the support pipe 41, that is, when the flow regulating ball 46 and the flow regulating plate 47 on the side of the connecting pipe 44 connected to the water outlet pipe are close to each other, the flow passing through the flow regulating ball 46 and the flow regulating plate 47 becomes smaller, which will increase the discharge pressure of the liquid outlet hole 48, and increase the flow between the flow regulating ball 46 and the flow regulating plate 47, which will reduce the discharge pressure of the liquid outlet hole 48, thereby adjusting the outlet pressure of the liquid outlet hole 48, and thereby adjusting the outlet pressure of the cleaning water;

[0046] Furthermore, the structure and function of the head changing mechanism 5 are described in detail below;

[0047] The head-changing mechanism 5 includes a head-changing disk 51, which is rotatably connected to the support cylinder 42, a ring gear 52 fixedly connected to the head-changing disk 51, a driving gear 43 rotatably connected to the support cylinder 42, the driving gear 43 and the ring gear 52 are engaged for transmission, and a power mechanism IV for driving the driving gear 43 to rotate is fixedly connected to the support cylinder 42. A plurality of liquid spraying channels 53 are provided on the head-changing disk 51, and the liquid spraying channels 53 can be communicated with the liquid outlet 48. A mounting seat 56 is provided on each of the plurality of liquid spraying channels 53, and a nozzle 57 is mounted on the mounting seat 56;

[0048] According to different usage requirements, multiple nozzles 57 are fixedly installed on multiple mounting bases 56 in advance, and each nozzle 57 is set to a different water outlet diameter, so that the multiple nozzles 57 can respectively spray water columns of different diameters and thicknesses;

[0049] The power mechanism IV is started. The power mechanism IV is preferably a servo motor. The output shaft of the power mechanism IV drives the drive gear 43 to rotate. The drive gear 43 drives the ring gear 52 to rotate. The ring gear 52 drives the head changing disk 51 to rotate. The head changing disk 51 drives the multiple nozzles 57 to rotate, thereby changing the positions of the multiple nozzles 57 so that different nozzles 57 can be connected to the liquid outlet 48. That is, when the spray channel 53 corresponding to the nozzle 57 moves to the position connected to the liquid outlet 48, the cleaning water sprayed from the liquid outlet 48 will enter the spray channel 53 and be sprayed out through the nozzle 57.

[0050] Furthermore, due to the different models of the nozzle 57, the nozzle 57 will spray water columns of different thicknesses. Under the condition that the water output of the cleaning mechanism 4 is constant, in order to control the impact force of the water column sprayed by the nozzle 57 model change;

[0051] The liquid spraying channel 53 is fixedly connected to an expansion cavity 54. The head changing plate 51 is provided with a plurality of pressure regulating pipes 55. The two ends of the pressure regulating pipes 55 are respectively connected to the expansion cavity 54 and the liquid spraying channel 53.

[0052] When the nozzle 57 is replaced with a water outlet diameter with a smaller diameter, the pressure inside the nozzle 57 increases, and the pressure in the corresponding spray channel 53 in the opposite direction will increase. The liquid in the spray channel 53 enters the expansion cavity 54 through the pressure regulating pipe 55, squeezing the expansion cavity 54, causing the expansion cavity 54 to expand. The expansion of the expansion cavity 54 squeezes the spray channel 53 to a certain extent, causing the spray channel 53 to narrow, thereby reducing the flow rate in the spray channel 53, and then dynamically controlling the impact force of the nozzle 57 spraying clean water. When the nozzle 57 is replaced with a water outlet diameter with a smaller diameter, the impact force of the nozzle 57 spraying clean water also becomes smaller accordingly, thereby achieving dynamic adjustment.
