Description

Technical Field

[0001] The invention relates to the technical field of stone engraving machines, in particular to a high-efficiency tombstone engraving machine. Background Art

[0002] Tombstone engraving machines mainly refer to the processing of the funeral industry, especially for the engraving of figures, text (character merits, political achievements) and other parts. Stone tombstone engraving machine is a high-tech fully automatic computer engraving equipment that can engrave characters on hard materials such as stone, tiles, glass, tombstones, and spirit tablets.

[0003] When engraving, it is necessary to spray water mist to remove dust, or use a dust collector to remove dust. When spraying, existing engraving machines often install a spray pipe next to the tool. The spray pipe moves with the movement of the tool and always points to the end of the tool. However, no matter how close the spray pipe is to the end of the tool, it can only spray one side of the tool. This makes it easy for dust to escape from the end far away from the spray pipe, or because of the high fluctuations on the surface of the stone blank, it is blocked, affecting the spray water flow to reach the processing position, resulting in the existing tombstone engraving machine. Dust is still widely generated, especially when multiple engraving machines are working at the same time, the dust is still large. Summary of the invention

[0004] In order to overcome the technical defects of the prior art, the present invention provides a high-efficiency tombstone engraving machine with low working dust.

[0024] The present invention will be further described below in conjunction with the accompanying drawings:

[0025] like Figure 1 and Figure 2 As shown, the present embodiment provides a high-efficiency tombstone engraving machine, including an engraving machine frame 1, a plurality of engraving machine heads 2, a machine head moving system 3 and a plurality of proximity spraying systems 4. Since a plurality of engraving machine heads 2 are provided, the processing is more efficient. Each proximity spraying system 4 is slidably installed at the end of the engraving machine head 2. A first water outlet gap 41 is formed between the upper end of the proximity spraying system 4 and the engraving machine head 2, and a second water outlet gap 44 is formed between the lower end of the proximity spraying system and the engraving machine head. The cross-sectional area of ​​the first water outlet gap 41 is not less than the cross-sectional area of ​​the second water outlet gap 44. After water flows out of the first water outlet gap 41, the proximity spraying system 4 is pushed down. Since the first water outlet gap 41 and the second water outlet gap 44 flow out water at the same time, and the cross-sectional area of ​​the first water outlet gap 41 is not less than the cross-sectional area of ​​the second water outlet gap 44, even if the downward pressure of the first water outlet gap 41 is not considered, and only under the gravity of the spraying system 4, the spraying system 4 It will also fall close to the workpiece, so that the spray system 4 is close to the cutting position of the engraving head 2, minimizing dust, and because the first water outlet slit 41 and the second water outlet slit 42 embrace the engraving head 2, the water flow can not only approach the processing position during engraving, but also evenly surround the processing position to prevent dust from escaping, thereby ensuring the dust removal effect. A guide plate 5 is provided on the engraving head 2, and a guide arc 51 is provided on the guide plate 5. The first water outlet slit 41 points to the guide plate 5, and the end of the guide arc 51 away from the first water outlet slit 41 bends downward to redirect the water downward. It is worth noting that due to the effect of the guide arc 51 guiding the water flow, the range of water spraying is increased. Each engraving head 2 is installed on the head moving system 3, and the head moving system 3 is used to change the position of the engraving head 2. The head moving system 3 is installed on the engraving frame 1 to drive the engraving head 2 to move.

[0026] Specifically, the engraving frame 1 includes a frame bottom plate 11 and two side walls 12. The frame bottom plate 11 is provided with a plurality of T-shaped fixing grooves for mounting the workpiece. After the workpiece is placed on the frame bottom plate 11, the workpiece is locked in the T-shaped fixing groove of the frame bottom plate 11 with a fixing block. The installation method of the workpiece on the T-shaped fixing groove is a prior art and will not be repeated here. The two side walls 12 are respectively installed at both ends of the frame bottom plate 11, and the head moving system 3 is slidably installed on the side wall 12 through a sliding guide rail to achieve translation. The sliding method of the head moving system 3 on the side wall 12 is a prior art and will not be repeated here.

[0027] Specifically, the head moving system 3 includes a sliding beam 31 and a plurality of lifting guide rails 32. A longitudinal movement motor is installed on the side wall 12 of the engraving frame 1, and a longitudinal movement screw is installed on the output end of the longitudinal movement motor. The longitudinal movement screw is connected to the sliding beam 31 through a threaded pair. The sliding beam 31 is connected to the longitudinal movement screw through a transmission connection to achieve longitudinal movement. The sliding beam 31 is then slidably installed on the side wall 12 of the engraving frame 1 in the longitudinal direction. A transverse movement motor is provided on the sliding beam 31, and a transverse movement screw is installed on the output end of the transverse movement motor. The transverse movement screws are respectively connected to the lifting guide rails 32 through a threaded pair. Each lifting guide rail 32 is connected to the transverse movement screw through a transmission connection to achieve transverse movement. A lifting motor is installed on the lifting guide rails 32. The engraving head 2 is slidably installed on the corresponding lifting guide rails 32. A lifting screw is installed on the output end of the lifting motor. The lifting screw is connected to the corresponding engraving head 2 through a transmission connection to achieve lifting.

[0028] Specifically, the sliding beam 31 is slidably mounted on the side wall 12 of the engraving frame 1 through a dovetail groove sliding pair, thereby achieving stable movement.

[0029] Specifically, each engraving head 2 includes an engraving motor, a milling cutter 21 and a spray sleeve 22. The engraving motor is installed on the head moving system 3, the milling cutter 21 is installed at the output end of the engraving motor, the spray sleeve 22 is installed on the body of the engraving motor, and the milling cutter 21 passes through the spray sleeve 22. The spray sleeve 22 is used to provide guidance for the approaching spray system 4.

[0030] Specifically, each proximity spray system 4 includes a sliding sleeve 42 and a water supply pipe 43 . The sliding sleeve 42 is sleeved outside the spray sleeve 22 . The water supply pipe 43 is connected to the sliding sleeve 42 to supply water to the sliding sleeve 42 .

[0031] Specifically, a second water outlet gap 44 is formed between the lower side of the sliding sleeve 42 and the spray sleeve 22. The cross-sectional area of ​​the second water outlet gap 44 is smaller than that of the first water outlet gap 41, thereby ensuring that after the water supply pipe 43 supplies water, the sliding sleeve 42 moves downward under the action of the water flow and its own gravity until it contacts the stone blank.

[0032] Specifically, an avoidance arc 45 is provided at the bottom of the sliding sleeve 42, so that the sliding sleeve 42 can move on the surface of the processed stone to achieve maximum dust removal. The sliding sleeve 42 is brought close to the processing position and has double upper and lower spraying. The spray height position of the sliding sleeve 42 is automatically adjusted according to the processing position, so that it follows the original curved surface of the processed surface and the stone blank, and the sliding sleeve 42 is raised and lowered in real time for adaptive spraying, thereby ensuring dust removal efficiency.
