[0017] Beneficial effects:

[0018] The processing box can store water for cleaning. The water is pumped out by a water pump, and then can be discharged from the output pipe 1 or the output pipe 2 for use under the control of the three-way solenoid valve. The water discharged from the output pipe 1 is used for flushing, and the water discharged from the output pipe 2 is used for cooling.

[0021] The left end of the plate roller is clamped inside the collar and positioned and clamped by rotating the positioning bolt. Then, the second electric push rod is started to push the plate roller to move to the right, so that the first abutting disc and the second abutting disc clamp the plate roller. At this time, the first abutting disc can be driven to rotate by starting the first motor, and the plate roller can be controlled to rotate together, thus realizing engraving processing;

[0022] When the first moving piece and the second moving piece move left and right repeatedly, the wedge block can be repeatedly squeezed to drive the guide plate to move and change the inclination degree, so that the debris adhered to the surface of the guide plate can be guided to different positions on the filter plate after being washed by water, making the debris filtration more uniform and avoiding the problem of accumulation and blockage;

[0023] Start the second motor to control the reciprocating lead screw to rotate. Under the guidance of the guide rod, the moving seat can be controlled to move to the right or left, so that the position of the laser engraver can be controlled, facilitating engraving of different positions of the plate roller.

Specific embodiments

[0031] To make the technical solution of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and specific embodiments.

[0032] Embodiment 1

[0033] As Figure 1 shown, a printing plate roller engraving device is provided, which includes a processing box 1. A water pump 7 is fixedly connected to the right side of the processing box 1. The input end of the water pump 7 is fixedly communicated with the right side inside the processing box 1. The output end of the water pump 7 is fixedly connected to a three-way solenoid valve 8. The top end and the right end of the output end of the three-way solenoid valve 8 are respectively fixedly communicated with a first output pipe 9 and a second output pipe 10;

[0034] The processing box 1 can store water for cleaning. The water is pumped out by the water pump 7, and thus, under the control of the three-way solenoid valve 8, it can be discharged for use from the first output pipe 9 or the second output pipe 10. The water discharged from the first output pipe 9 is used for flushing, and the water discharged from the second output pipe 10 is used for cooling. It is possible to control the two output ends of the three-way solenoid valve 8 to be alternately opened, so that the water is alternately sprayed out from the first output pipe 9 and the second output pipe 10 for use.

[0035] As Figure 4As shown in the figure, a flow dividing cavity 11 is fixedly communicated with both the rear and the front inside the processing box 1. A first moving piece 12 and a second moving piece 13 are respectively slidably connected to the left and right inside the flow dividing cavity 11.

The toothed ring 16 is meshed with the rack 14;

[0036] By using the first moving piece 12 and the second moving piece 13 to move left and right repeatedly along the inside of the flow dividing cavity 11 and cooperating with the meshing connection with a plurality of toothed rings 16, a plurality of cleaning nozzles 15 can be driven to swing left and right repeatedly, thereby increasing the water outlet range and making the flushing range more extensive.

[0037] As Figure 3 and Figure 5 As shown in the figure, a first motor 4 is arranged on the right side of the processing box 1. A toothed disc 5 is fixedly connected to the outer side wall of the output shaft of the first motor 4. An arc-shaped tooth 6 is integrally formed on the outer side wall of the toothed disc 5. The top end of a first output pipe 9 is fixedly communicated with a transfer cavity 17. A flow dividing pipe 18 is fixedly communicated between the transfer cavity 17 and each of the two flow dividing cavities 11.

When the gear 21 is not meshed with the arc-shaped tooth 6, under the pulling of the first spring 22, the second moving piece 13 moves left, and the traction rope 23 will drive the winding column 19 to rotate and reset under the pulling, thus realizing the effect of the rack 14 moving left and right repeatedly.

An inner side of the L-shaped bracket 24 is fixedly connected with a right side of a first motor 4. A right end of an output shaft of the first motor 4 is located inside the processing box 1 and is fixedly connected with a first abutting disc 25.

An outer side wall of each pressing piece 34 is fixedly connected with a sealing flap 35. An upper surface of the sealing flap 35 is attached to an upper surface of the flow dividing cavity 11;

[0044] When the first moving piece 12 and the second moving piece 13 move left and right repeatedly, they will drive the squeezing piece 34 to move left and right repeatedly. Thus, by repeatedly squeezing the wedge block 30, the guiding plate 29 can be driven to move, changing the inclination degree, so that the debris adhered to the surface of the guiding plate 29 can be guided to different positions on the filter plate 32 after being washed by water, making the debris filtration more uniform and avoiding the problem of accumulation and blockage.
