[0040] See also Figure 1 and Figure 2 , this embodiment provides a double-headed precision engraving machine with a dust removal function, including a base 10, a bracket 20, an engraving assembly 30, a first drive assembly 40, a dust removal assembly 50 and a second drive assembly 60, the bracket 20 is fixedly mounted on the upper part of the base 10, the engraving assembly 30 is arranged on the inner side of the bracket 20, the first drive assembly 40 is used to drive the engraving assembly 30 to move downward to drive the engraving assembly 30 to contact the upper surface of the workpiece to be engraved, the dust removal assembly 50 is arranged around the outside of the engraving assembly 30, and the second drive assembly 60 is arranged on the inner side of the dust removal assembly 50. When the engraving assembly 30 engraves the workpiece, the second drive assembly 60 is used to control the operation of the dust removal assembly 50 to collect the dust generated during the engraving process.

[0041] When engraving a workpiece, the workpiece to be engraved can be placed on the upper part of the base 10, and then the first driving component 40 is used to drive the engraving component 30 to move downward, so that the engraving component 30 contacts the upper surface of the workpiece to be engraved, and then the workpiece is engraved. During this process, the dust removal component 50 is controlled by the second driving component 60 to collect the dust generated during the engraving process to prevent the dust from diffusing into the surrounding working environment, thereby preventing the staff from inhaling the dust and threatening the physical and mental health of the staff.

[0042] See also Figure 1 In one embodiment, the first driving component 40 includes a hydraulic cylinder 401, which is fixedly mounted on the inner top wall of the bracket 20. The output end of the hydraulic cylinder 401 is connected to a lifting plate 402. The engraving component 30 includes a motor 303, a rotating shaft 302 and a carving knife 301. The motor 303 is fixedly mounted on the upper part of the lifting plate 402. One end of the rotating shaft 302 is connected to the output end of the motor 303, and the other end passes through the lifting plate 402 and is connected to the carving knife 301.

[0043] After the workpiece to be engraved is placed on the upper part of the base 10, the hydraulic cylinder 401 is used to drive the lifting plate 402 to move downward along the inner side of the bracket 20, thereby driving the motor 303, the rotating shaft 302 and the engraving knife 301 to move downward as a whole, so that the engraving knife 301 contacts the upper surface of the workpiece, and then the motor 303 drives the rotating shaft 302 to rotate, thereby driving the engraving knife 301 to rotate, and the upper surface of the workpiece is engraved by the rotating engraving knife 301.

[0044] See also Figure 3 In one embodiment, the dust removal assembly 50 includes a dust collecting assembly 501 and a piston assembly 502. The dust collecting assembly 501 is fixedly installed at the bottom of the lifting plate 402, and the piston assembly 502 is arranged inside the dust collecting assembly 501. The second driving assembly 60 is used to drive the piston assembly 502 to move up and down inside the dust collecting assembly 501 to suck the dust generated during the workpiece engraving process into the dust collecting assembly 501 for storage.

[0045] See also Figure 3 、 Figure 4 and Figure 5In one embodiment, the dust collecting assembly 501 includes an outer cylinder 5011 and an inner ring plate 5012, the inner ring plate 5012 is arranged inside the outer cylinder 5011, the rotating shaft 302 passes through the inner ring plate 5012 along the central axis of the inner ring plate 5012, an air inlet 5016 is opened at the bottom of the outer cylinder 5011, the side wall of the outer cylinder 5011 is connected to the exhaust pipe 5014, the exhaust pipe 5014 is provided with a one-way valve, and the inner wall of the outer cylinder 5011 is provided at the mouth of the exhaust pipe 5014. There is a partition net 5019, and a one-way air intake assembly is provided on the inner bottom wall of the outer cylinder 5011. The piston assembly 502 includes a piston block 5021, and the piston block 5021 is arranged between the outer cylinder 5011 and the inner ring plate 5012. The upper part of the piston block 5021 is connected to the inner top wall of the outer cylinder 5011 through the second elastic member 5023. The second drive assembly 60 is arranged on the inner side of the inner ring plate 5012 and cooperates with the second elastic member 5023 to drive the piston block 5021 to move back and forth up and down.

[0046] When the engraving tool 301 is engraving the workpiece, the piston block 5021 is driven to move back and forth between the outer cylinder 5011 and the inner ring plate 5012 through the cooperation of the second driving assembly 60 and the second elastic member 5023. When the piston block 5021 moves upward, the dust generated during the engraving process can be extracted from the air inlet hole 5016 to between the outer cylinder 5011 and the inner ring plate 5012. When the piston block 5021 moves downward, the air between the outer cylinder 5011 and the inner ring plate 5012 can be pressed out from the exhaust pipe 5014. At this time, the dust entering between the outer cylinder 5011 and the inner passage 5012 can be intercepted by the partition net 5016 to prevent the dust from being pressed out from the exhaust pipe 5014 along with the air.

[0047] See also Figure 5 In one embodiment, the one-way air intake assembly includes a baffle 5017 and a first elastic member 5018. The baffle 5017 is hingedly arranged on the inner bottom wall of the outer tube 5011 to seal the air intake hole 5016. One end of the first elastic member 5018 is connected to the baffle 5017, and the other end is connected to the inner wall of the outer tube 5011 to provide elastic support for the baffle 5017.

[0048] When the piston block 5021 moves upward, the dust generated during the engraving process can be sucked into the space between the outer cylinder 5011 and the inner ring plate 5012 through the air inlet 5016 together with the outside air. At this time, the outside air pushes the baffle 5017 to rotate inward of the outer cylinder 5011, and the first elastic member 5018 is compressed, thereby releasing the blockage of the air inlet 5016. When the piston block 5021 moves downward, the air between the outer cylinder 5011 and the inner ring plate 5012 can be pressed out from the exhaust pipe 5014.

[0049] See also Figure 2 and Figure 3 In one embodiment, the second drive assembly 60 includes a rotating plate 601 and an annular protrusion 602, the rotating plate 601 is arranged on the inner side of the inner ring plate 5012 and is fixedly connected to the rotating shaft 302, the annular protrusion 602 is fixedly installed on the upper part of the rotating plate 601, and the upper surface of the annular protrusion 602 is provided with a plurality of arc-shaped recessed portions 603 and a plurality of arc-shaped protrusions 604, and the plurality of arc-shaped recessed portions 603 and the plurality of arc-shaped protrusions 604 are alternately distributed, and a sliding groove 5015 is provided on the inner ring plate 5012, and an L-shaped connecting rod 5022 is fixedly provided on one side of the piston block 5021, and the end of the L-shaped connecting rod 5022 away from the piston block 5021 extends from the sliding groove 5015 to the inner side of the inner ring plate 5012 and abuts against the upper surface of the annular protrusion 602.

[0050] When the motor 303 drives the rotating shaft 302 to rotate, thereby driving the carving knife 301 to rotate and then carving the workpiece, the rotating shaft 302 can also drive the rotating plate 601 to rotate, and then the annular protrusion 602 rotates. Since one end of the L-shaped connecting rod 5022 abuts against the upper surface of the annular protrusion 602, when the annular protrusion 602 rotates, one end of the L-shaped connecting rod 5022 can slide along the plurality of arc-shaped recessed portions 603 and the plurality of arc-shaped protrusions 604 in sequence. 04, the arc-shaped protrusion 604 can push the L-shaped connecting rod 5022 to slide upward along the slide groove 5015, thereby driving the piston block 5021 to move upward, so as to draw the dust from the air inlet 5016 to be stored between the outer cylinder 5011 and the inner ring plate 5012. When one end of the L-shaped connecting rod 5022 slides over the arc-shaped recessed portion 603, the second elastic member 5023 pushes the piston block 5021 to move downward, so as to press the air between the outer cylinder 5011 and the inner ring plate 5012 out from the exhaust pipe 5014.

[0051] See also Figure 3 、 Figure 4 and Figure 5In one embodiment, a plurality of partitions 5013 are provided between the outer cylinder 5011 and the inner ring plate 5012, and the plurality of partitions 5013 divide the area between the outer cylinder 5011 and the inner ring plate 5012 into a plurality of dust collection spaces.

The upper surface of the annular protrusion 602 is abutted, and the exhaust pipes 5014 are provided in several groups, and the exhaust pipes 5014 are distributed in an annular manner around the outer cylinder 5011. One end of each group of exhaust pipes 5014 is connected to a group of dust collection spaces, and the other end extends obliquely toward the center position below the outer cylinder 5011. Several groups of air inlet holes 5016 are distributed in an annular manner at the bottom of the outer cylinder 5011, and each group of air inlet holes 5016 is connected to a group of dust collection spaces.

The dust collection effect is improved; and since the exhaust pipes 5014 are arranged in a ring-shaped interval and a plurality of groups, one end of each group of exhaust pipes 5014 extends obliquely toward the center position below the outer tube 5011, when the air is pressed out from the plurality of exhaust pipes 5014, a plurality of air flows blowing toward the center position below the outer tube 5011 can be formed. Under the blowing of the plurality of air flows, the scattered dust can be driven to gather toward the center position below the outer tube 5011, thereby further preventing the dust from being scattered and improving the dust collection effect.
