Description

Technical Field

[0001] This invention relates to cleaning machines, and more specifically to multi-nozzle mechanically switching high-pressure cleaning machines. Background Technology

[0002] Traditional high-pressure washers 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 rinsing, fine decontamination, or high-pressure cutting. When a nozzle needs to be replaced, the operator must manually disassemble and install the new nozzle, which is not only time-consuming and labor-intensive but may also cause wear and tear on the interfaces or failure of the seals due to frequent operation. Furthermore, different nozzles have different requirements for spray angle, flow rate, and pressure, but traditional washers usually only provide a fixed pressure output or require manual adjustment. If the pressure is mismatched with the nozzle, it may lead to poor cleaning results, such as insufficient pressure, or equipment overload, such as excessive pressure. Summary of the Invention

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

[0036] The clamping mechanism 2 comprises a sliding seat 21 which is slidingly connected to the connecting bracket 13, the sliding seat 21 is threadedly connected to the screw rod II 14, the sliding seat 21 is fixedly connected with an extension mechanism I 22, the extension end of the extension mechanism I 22 is fixedly connected with a rotary motor 23, the output shaft of the rotary motor 23 is fixedly connected with a clamping bracket 24, the clamping bracket 24 is rotatably connected with two clamping wheels 25, and the two clamping wheels 25 are drivingly connected with a clamping belt 26;

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

[0038] In use, the parts to be cleaned are placed between the two clamping belts 26, the extension mechanism I 22 is started, which can be a hydraulic cylinder or an electric push rod, the extension end of the extension mechanism I 22 drives the rotary motor 23 to move, 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 parts, and then the parts are clamped by the mutual approach of the two clamping belts 26;

[0039] Further, the rotary motor 23 is started, which is preferably a servo motor, the output shaft of the rotary 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, and then the angle of the parts is adjusted to realize the overall cleaning of the parts;

[0040] Further, in order to realize the overall cleaning of the parts, the power mechanism III is started, which is preferably a servo motor, the output shaft of the power mechanism III drives the clamping wheel 25 to rotate, the clamping wheel 25 drives the clamping belt 26 to move, so that the clamping belt 26 drives the parts to move, and then the contact position between the parts and the clamping belt 26 is adjusted to realize the overall cleaning of the parts;

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

[0042] As shown in the figure, Figure 5 The cleaning mechanism 4 comprises a support pipe 41, a support cylinder 42 is fixedly connected to the middle part of the support pipe 41, the support cylinder 42 communicates with the support pipe 41, the support pipe 41 is fixedly connected between the two swing brackets 33, the lower end of the support cylinder 42 is provided with a liquid outlet hole 48, and the support pipe 41 is fixedly connected with two connecting pipes 44;

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

[0044] Furthermore, in order to control the liquid outlet pressure of the liquid outlet 48, two flow regulating plates 47 are fixedly connected inside the support pipe 41, and a telescopic mechanism II 45 is fixedly connected to the swing bracket 33. 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 press against the flow regulating plate 47.

[0045] Activate the telescopic mechanism II 45, which 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, adjusting the distance between the flow regulating ball 46 and the flow regulating plate 47. The flow regulating plate 47 is provided with an arc hole, thereby adjusting the flow rate between the flow regulating ball 46 and the flow regulating plate 47, and thus controlling the flow rate 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 outlet pipe move closer to each other, the flow rate between the flow regulating ball 46 and the flow regulating plate 47 decreases, which increases the discharge pressure of the outlet hole 48. The flow rate between the flow regulating ball 46 and the flow regulating plate 47 increases, which decreases the discharge pressure of the outlet hole 48, thereby adjusting the discharge pressure of the outlet hole 48, and thus adjusting the discharge pressure of the cleaning water.

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

[0047] The head-changing mechanism 5 includes a head-changing disk 51, which is rotatably connected to a support cylinder 42. A gear ring 52 is fixedly connected to the head-changing disk 51. A drive gear 43 is rotatably connected to the support cylinder 42. The drive gear 43 and the gear ring 52 mesh and drive each other. A power mechanism IV that drives the drive gear 43 to rotate is fixedly connected to the support cylinder 42. The head-changing disk 51 is provided with multiple spray channels 53, which can communicate with the liquid outlet 48. Each of the multiple spray channels 53 is provided with a mounting base 56, and a nozzle 57 is mounted on the mounting base 56.

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

[0049] The power mechanism IV is preferably a servo motor. The output shaft of the power mechanism IV drives the driving gear 43 to rotate, the driving gear 43 drives the gear ring 52 to rotate, the gear ring 52 drives the head changing disc 51 to rotate, the head changing disc 51 drives the plurality of nozzles 57 to rotate, thereby changing the positions of the plurality of nozzles 57, so that different nozzles 57 can be in communication with the liquid outlet hole 48, that is, when the nozzle 57 corresponding to the liquid spraying channel 53 moves to the communication position with the liquid outlet hole 48, the cleaning water sprayed from the liquid outlet hole 48 will enter the liquid spraying channel 53 and be sprayed through the nozzle 57;

[0050] Further, since the nozzles 57 are of different types, the nozzles 57 will spray water columns of different diameters. In the case 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 nozzles 57 due to the change of the type of the nozzles 57;

[0051] The liquid spraying channel 53 is fixedly connected with an expansion cavity 54, and the head changing disc 51 is provided with a plurality of pressure regulating pipes 55, both ends of the pressure regulating pipe 55 being connected with the expansion cavity 54 and the liquid spraying channel 53 respectively.

[0052] When the nozzle 57 is replaced by a nozzle with a smaller water outlet diameter, the pressure inside the nozzle 57 becomes larger, and the pressure in the corresponding liquid spraying channel 53 reversely becomes larger. The liquid in the liquid spraying channel 53 enters the expansion cavity 54 through the pressure regulating pipe 55, and the expansion cavity 54 is extruded, so that the expansion cavity 54 expands, and the expansion cavity 54 extrudes the liquid spraying channel 53, so that the liquid spraying channel 53 is narrowed, thereby reducing the flow in the liquid spraying channel 53, and dynamically controlling the impact force of the cleaning water sprayed by the nozzle 57. When the nozzle 57 is replaced by a nozzle with a smaller water outlet diameter, the impact force of the cleaning water sprayed by the nozzle 57 also becomes smaller, and dynamic adjustment is realized.
