[0015] Compared with the prior art, the above technical solution of the present invention has the following beneficial technical effects: The starting motor drives the bidirectional lead screw to rotate, thereby driving the moving shell above the moving part to move along the axial direction of the bidirectional lead screw to clamp the stone. At this time, the second inclined portion contacts the stone, and the stone is limited to the center above the support frame through the second inclined portions on the two moving shells, thereby achieving clamping and limiting of stones of different sizes, and by starting the vacuum cleaner, the flying dust is sucked into the moving shell, and then sucked into the vacuum cleaner through the moving shell along the dust suction telescopic tube, thereby achieving the ability to adjust the position of the moving shell according to the size of the stone, avoiding the situation where the moving shell is too far away from the stone, resulting in insufficient suction and some dust flying out.

[0016] When the movable shell moves toward the stone, it drives the piston shaft 1 to move in the inner cavity of the cylinder 1 toward the water delivery unit, thereby delivering the water in the cylinder 1 from the water delivery unit to the cylinder 3. The larger the stone, the shorter the moving distance of the movable shell, and therefore the shorter the moving distance of the piston shaft 1 in the cylinder 1. When the movable shell stops moving, the water delivery unit operates to deliver the quantitative water in the inner cavity of the cylinder 1 to the cylinder 3 to be squeezed by the piston shaft 2, thereby achieving the quantitative water required for spraying according to the size of the stone, thereby avoiding waste of water resources.

[0017] The second inclined portion is squeezed by the stone and drives the first inclined portion away from the inclined plug and toward the L rod, causing the diamond block to drop and releasing the limit on the rotating rod one. Subsequently, the rotating rod one is driven by the elasticity of the elastic member two to move toward the L rod and over the top of the diamond block. However, since the inclined portion one moves toward the L rod at the same time, the rotating rod one is still above the inclined portion one at this time, and the blocking portion is still located at the connection between the circular tube two and the tube four, blocking the water in the inner cavity of the tube three. After the laser engraving portion engraves the stone with a laser, the bidirectional lead screw reverses and drives the movable shell to leave the stone. At this time, the inclined portion two is elastically reset by the elastic member four, and the through-hole plate two loses the support of the inclined portion two and drops, thereby closing the through-hole plate one and the through-hole plate two, thereby realizing the closure of the movable shell when water is about to be sprayed on the stone, thereby preventing water vapor from entering the movable shell and causing the vacuum cleaner to be damaged by moisture.

[0018] At this time, the inclined portion 1 is reset, the inclined portion 1 moves toward the inclined plug block, and the rotating rod 1 descends due to the elasticity of the spring 2, so that the blocking portion leaves the connection between the round tube 2 and the cylinder 4, and the spring 1 in the inner cavity of the cylinder 3 generates elasticity to drive the piston shaft 2 to descend in the inner cavity of the cylinder 3, and a certain amount of water in the inner cavity of the cylinder 3 is sprayed from the cylinder along the round tube 2 to the surface of the stone, thereby washing away some dust on the surface of the stone that is difficult to suck out, thereby ensuring that the surface of the stone is clean after the laser engraving is completed, and the stone is not rinsed until the laser engraving is completed, thereby avoiding the scattering of the laser beam caused by the water flow during the laser engraving process, thereby reducing the energy density of the laser, etc.

[0019] In the process of water entering the inner cavity of cylinder three, piston shaft two rises, driving rack to rise, and through the meshing of rack and gear one and gear one and gear two, gear two is driven to rotate, and gear two drives the cylinder to rotate, so that the cylinder is aligned with the stone. The longer the stone, the more water enters the inner cavity of cylinder three, and the farther the piston shaft two rises. In the process of piston shaft two driving the rack to rise, the angle of the cylinder is adjusted to align with the center of stones of different lengths, and when the spraying starts, the water in the inner cavity of cylinder three decreases and piston shaft two descends, thereby adjusting the spray angle of the cylinder from the center of the stone to both sides of the stone, thereby realizing the adjustment of the spray angle according to the size of the stone and ensuring uniform spraying of stones of different sizes. When the spraying is about to end, the cylinder is aligned with the inclined plate, so that part of the water flows to the surface of through-hole plate one and through-hole plate two, washing the dust on the surface of through-hole plate one and through-hole plate two.

The water spraying mechanism includes a pumping assembly, a water storage assembly, a switch assembly, a limiting assembly, an elastic member 4 33 and an inclined portion 1 34; the two ends of the elastic member 4 33 are respectively connected to the movable shell 12 and the inclined portion 1 34; the pumping assembly is installed on the support frame 1, and its movable end is connected to the movable shell 12 and moves with the movable shell 12; the water inlet end of the water storage assembly is connected to the water outlet end of the pumping assembly; the water inlet end of the switch assembly is connected to the water outlet end of the water storage assembly, and its spraying end is installed on the movable shell 12; the movable end of the switch assembly slides against the inclined portion 1 34 and is limited by the limiting assembly; the limiting assembly is installed in the inclined portion 1 34; the driving mechanism drives the movable shell 12 close to the stone, and the movable shell 12 drives the pumping assembly to transport water to the water outlet assembly. After the stone carving is completed, the switch assembly and the limiting assembly are separated, and water is sprayed onto the stone from the spraying end of the switch assembly.

[0024] The pumping assembly includes a piston shaft 13, a cylinder 14, a round tube 15, a cylinder 2 16, an elastic member 17, a C-shaped rod 18 and a plug 19; Cylinder 14 is installed on the support frame 1; the small end of piston shaft 13 is connected to the movable shell 12, and the large end of piston shaft 13 is movably sleeved in cylinder 14; circular tube 15 is connected to cylinder 14; cylinder 2 16 is connected to circular tube 15; the two ends of elastic member 17 are respectively connected to circular tube 15 and C-shaped rod 18; the two ends of C-shaped rod 18 are respectively connected in cylinder 14, supported by piston shaft 13 and connected to plugging head 19; plugging head 19 is movably sleeved in cylinder 2 16; when piston shaft 13 moves toward movable shell 12, C-shaped rod 18 separates from piston shaft 13, and elastic member 17 pulls C-shaped rod 18 to drive plugging head 19 to move to the connection between circular tube 15 and cylinder 2 16.

[0025] The water storage assembly includes a water delivery unit 20, a cylinder 3 21, a spring 1 22 and a piston shaft 2 23; The two ends of the water transfer unit 20 are respectively connected to the water outlet end of the pumping assembly and the bottom of the cylinder three 21; the two ends of the spring 1 22 are respectively connected to the cylinder three 21 and the piston shaft 2 23; the water in the water outlet assembly is transported to the cylinder three 21, driving the piston shaft 2 23 to rise in the cylinder three 21.

[0026] A pressure relief valve is installed on the large end of the piston shaft 13. When the piston shaft 13 moves in the inner cavity of the cylinder 14, the water is squeezed and the excess water passes through the large end of the piston shaft 13 through the pressure relief valve.

[0027] Connect an external water source to circular pipe 15. In the initial state, the plug 19 blocks circular pipe 15, and the external water source delivers water to barrel 14. When the movable shell 12 moves to clamp and position stones of different sizes, it drives the piston shaft 13 to move to different positions in barrel 14. The larger the stone, the shorter the distance the piston shaft 13 moves, and the more water is in the inner cavity of barrel 14 on the side of the piston shaft 13 away from circular pipe 15. Then, the water delivery unit 20 is activated to deliver the water in the inner cavity of barrel 14 on the side of the piston shaft 13 away from circular pipe 15 to barrel 3 21. Due to the pressure relief valve on the piston shaft 13, the water on the other side of the piston shaft 13 will not enter barrel 3 21. After the stone processing is completed, the movable shell 12 drives the piston shaft 13 to move toward the C-shaped rod 18 in the inner cavity of the cylinder 14 for reset. The large end of the piston shaft 13 squeezes the water located on the side of the piston shaft 13 in the inner cavity of the cylinder 14 close to the C-shaped rod 18 again, so that the water passes over the piston shaft 13 and enters the other side of the piston shaft 13 in the inner cavity of the cylinder 14.

[0028] The water delivery unit 20 is composed of a water delivery telescopic pipe and a water pump, and the water pump is installed on the water delivery telescopic pipe.

[0029] The switch assembly includes a second round tube 24, a fourth cylinder 25, a second spring 26, a blocking portion 27, a second elastic member 28, a second rectangular plate 29, a third elastic member 30, a first rotating rod 31, a cylinder 32, and an L-shaped rod 37; The two ends of the circular tube 24 are respectively connected to the water outlet end of the water storage assembly and the rotating connecting cylinder 32; the cylinder 32 is mounted on the movable shell 12; the cylinder 4 25 is mounted on the circular tube 24; the two ends of the spring 26 are respectively connected to the cylinder 4 25 and the blocking portion 27; the blocking portion 27 passes through the cylinder 4 25 and is connected to the elastic member 2 28; the two ends of the elastic member 28 are respectively connected to the blocking portion 27 and the rectangular plate 29; the two ends of the elastic member 30 are respectively connected to the rectangular plate 29 and the rotating rod 1 31; the rotating rod 1 31 abuts against the inclined portion 1 34 The L rod 37 is mounted on the support frame 1 and is located on the moving path of the rectangular plate 29; the limit assembly is unlocked, the rotating rod 1 31 moves along the inclined portion 1 34 toward the L rod 37, and the inclined portion 1 34 also moves at this time. The rotating rod 1 31 is still in contact with the inclined portion 1 34. When the inclined portion 1 34 moves toward the movable shell 12 to reset, the rotating rod 1 31 is separated from the inclined portion 1 34, and the rectangular plate 2 29 drives the blocking portion 27 to descend in the cylinder 4 25. At this time, the water in the circular tube 24 enters the cylinder 32.

[0030] The limiting assembly includes an elastic member 5 35, a diamond block 36 and an inclined insert block 38; The two ends of the elastic member 5 35 are respectively connected to the inclined portion 1 34 and the diamond block 36; the inclined surface insert 38 is installed on the movable housing 12 and inserted into the inclined portion 1 34 to lift the diamond block 36; the diamond block 36 limits the rotating rod 1 31; when the inclined portion 1 34 moves toward the L-bar 37, the inclined surface insert 38 leaves the inclined portion 1 34 and below the diamond block 36, and the elastic member 5 35 drives the diamond block 36 to descend and separate from the rotating rod 1 31.

[0031] After the stone processing is completed, the movable shell 12 moves toward the L rod 37. At this time, the rotating rod 1 31 is not located above the inclined portion 1 34. As the movable shell 12 moves toward the L rod 37, the rectangular plate 29 is supported by the L rod 37. As the movable shell 12 continues to move, the rotating rod 1 31 at the bottom end of the rectangular plate 29 moves along the inclined surface of the inclined portion 1 34 to the top of the inclined portion 1 34, and through the elasticity of the elastic member 30, the rotating rod 1 31 passes over the top of the diamond block 36 and is limited by the diamond block 36. At this point, the whole stone carving process is completed. The rotating rod 1 31 is limited by the diamond block 36, so that when the movable shell 12 starts to move toward the stone, the rotating rod 1 31 is located above the inclined portion 1 34, and the blocking portion 27 blocks the connection between the circular tube 2 24 and the cylinder 4 25, so that the water entering the inner cavity of the cylinder 3 21 will not be discharged through the circular tube 2 24.

[0032] Example 2, as Figure 2 、 5, 6 and 8 , a stone laser engraving device proposed by the present invention, compared with the first embodiment, the adjustment mechanism of this embodiment includes a rack 39, a gear 1 40, a gear 2 41 and an inclined plate 47; The rack 39 is connected to the small end of the piston shaft 23; the gear 1 40 is installed on the movable shell 12; the gear 1 40 is respectively engaged with the rack 39 and the gear 2 41; the gear 2 41 is connected to the spray end of the switch assembly; the tilting plate 47 is installed on the movable shell 12.

[0033] A rectangular hole is provided above the movable shell 12 , and the rectangular hole is provided above the through-hole plate 1 45 . When the cylinder 32 is about to finish spraying, the cylinder 32 sprays water onto the top of the inclined plate 47 , and then the water flows through the rectangular hole onto the surface of the through-hole plate 1 45 and the through-hole plate 2 46 .

[0034] Because the diameter of gear 1 40 is larger than that of gear 2 41 , the rotation of gear 1 40 can accelerate the rotation of gear 2 41 , so that the angle of cylinder 32 can move faster, thereby ensuring that the water sprayed by cylinder 32 can completely cover the surface of the stone. In order to ensure that cylinder 32 can spray water onto the surface of the stone, gears 1 40 and gears 2 41 of different diameters can be freely selected.

[0035] Example 3, as Figure 1 、 2 As shown in Figures 8-10 , the stone laser engraving device proposed by the present invention, compared with the first embodiment, the dust collection mechanism of this embodiment includes a dust collector 42 , a dust collection telescopic tube 43 , a second inclined portion 44 , a first through-hole plate 45 and a second through-hole plate 46 ; The suction end of the vacuum cleaner 42 is connected to the movable shell 12; the inclined portion 1 34 passes through the movable shell 12 and is connected to the inclined portion 2 44; the through-hole plate 1 45 is slidably connected in the movable shell 12, and the through-hole plate 2 46 is installed in the movable shell 12; the through-hole plate 1 45 and the through-hole plate 2 46 fit together; the inclined portion 2 44 moves toward the inclined portion 1 34 to push the through-hole plate 1 45 upward, and the through holes of the through-hole plate 1 45 and the through-hole plate 2 46 are located at the same position, and the movable shell 12 is connected to the outside.

[0036] The bottom of the through-hole plate 1 45 is provided with a rotating rod 2.

[0037] The driving mechanism includes a motor 8, a bidirectional lead screw 9, a moving part 10 and a guide rod 11; The motor 8 is installed on the support frame 1, and its output shaft is connected to the bidirectional screw 9; the surface of the bidirectional screw 9 is threaded with the moving part 10; the guide rod 11 is installed in the support frame 1, and the moving part 10 is movably sleeved on the guide rod 11.

[0038] Example 4, as Figure 1As shown, the stone laser engraving device proposed by the present invention, compared with the embodiment 1, the laser engraving mechanism of this embodiment includes a driving device 1 2, a moving platform 3, a driving device 2 4, a laser engraving part 5, a cylinder 6, a rectangular plate 1 7 and a placement plate 48; Driving device 1 2 is installed in the support frame 1, and its driving end is connected to the movable platform 3, the movable platform 3 is connected to driving device 2 4, and the driving end of driving device 2 4 is connected to the laser engraving part 5; driving device 2 4 is connected to cylinder 6, and the output end of cylinder 6 is connected to rectangular plate 1 7; a placing plate 48 is installed on the support frame 1 for supporting the stone.

[0039] Start the cylinder 6 to drive the rectangular plate 7 to rise, then place the stone on the placement plate 48, and then start the cylinder 6 again to drive the rectangular plate 7 to descend and rest against the top of the movable table 3, so that when the driving device 1 2 drives the movable table 3 to move, the movable table 3 can drive the driving device 2 4 to move along the driving device 1 2, and the driving device 2 4 drives the laser engraving part 5 to move along the driving device 2 4.

[0040] Two limiting rods are installed above the movable platform 3 connected to the rectangular plate 7, and the rectangular plate 7 is stuck in the two limiting rods.

[0041] A drainage pipe is installed at the bottom end of the support frame 1. After the water is sprayed on the stone, it is discharged through the drainage pipe at the bottom end of the support frame 1.

[0042] In summary, in the present invention, the cylinder 6 is started to drive the rectangular plate 7 to rise, and then the stone is placed on the placement plate 48. Then, the cylinder 6 is started to drive the rectangular plate 7 to descend and clamp it on the movable platform 3. Then, the driving device 2 and the movable platform 3 are started to adjust the position of the laser engraving part 5, so that the laser engraving part 5 moves to the specified position. Then, the motor 8 is started to drive the bidirectional screw 9 to rotate, and the bidirectional screw 9 drives the moving part 10 to move along the axial direction of the bidirectional screw 9 and the guide rod 11, thereby driving the movable shell 12 to move toward the direction of the stone. At this time, the inclined portion 2 44 contacts the stone, so that the stone pushes the inclined portion 2 44 toward the direction of the movable shell 12, and the inclined portion 2 44 pushes the through-hole plate 1 45 upward, so that the through holes of the through-hole plate 1 45 and the through-hole plate 2 46 are located in the same position, thereby making the movable shell 12 connected to the outside.

[0043] When the second inclined portion 44 drives the first inclined portion 34 to move toward the L-rod 37, the inclined surface insert 38 leaves the inner cavity of the first inclined portion 34, thereby causing the inclined surface insert 38 to leave the bottom of the diamond block 36. Then, the diamond block 36 is pulled down by the elasticity of the fifth elastic member 35. At this time, the diamond block 36 is separated from the first rotating rod 31, and then the elasticity of the second elastic member 28 can drive the second rectangular plate 29 to move toward the direction of the L-rod 37. However, at this time, the first inclined portion 34 also moves toward the first inclined portion 34, so that the second rectangular plate 29 can only pass over the top of the diamond block 36.

[0044] When the movable shell 12 moves toward the stone, it drives the piston shaft 13 to move in the inner cavity of the cylinder 14. When the stone is larger, the distance that the piston shaft 13 moves after passing the circular tube 15 is shorter. Then the water delivery unit 20 is started to deliver the water in the inner cavity of the cylinder 14 on the side of the piston shaft 13 close to the movable shell 12 to the cylinder 3 21. When the piston shaft 13 moves, the piston shaft 13 separates from the C-shaped rod 18. At this time, the C-shaped rod 18 drives the plugging head 19 to block the connection between the circular tube 15 and the cylinder 2 16, thereby preventing excess water from entering the cylinder 14, resulting in an increase in the water pressure in the inner cavity of the cylinder 14 on the side of the piston shaft 13 close to the C-shaped rod 18, causing excess water to enter the cylinder 3 21.

[0045] The water entering the inner cavity of cylinder three 21 squeezes piston shaft two 23 to move upward, piston shaft two 23 drives rack 39 to move upward, rack 39 drives gear one 40 to rotate, gear one 40 drives gear two 41 to rotate, thereby driving cylinder 32 to adjust the spray angle to the center of the stone.

[0046] Then the laser engraving unit 5 engraves the stone with a laser. During the engraving process, the vacuum cleaner 42 is started to generate suction, sucking the dust flying during the engraving process into the movable shell 12 and then into the vacuum cleaner 42 along the dust suction telescopic tube 43.

[0047] After the engraving is completed, the two-way lead screw 9 rotates and drives the movable shell 12 to move a distance toward the L rod 37, so that the inclined portion 2 44 is separated from the stone. At this time, the inclined portion 1 34 moves toward the movable shell 12, so that the rotating rod 1 31 descends along the inclined portion 1 34 and leaves the upper part of the inclined portion 1 34. The rectangular plate 29 drives the blocking portion 27 to descend in the inner cavity of the cylinder 4 25 and leave the connection between the circular tube 24 and the cylinder 4 25, so that the spring 1 22 squeezes the water in the inner cavity of the cylinder 3 21. The squeezed water is sprayed from the cylinder 32 along the circular tube 24 onto the stone, and as the water in the inner cavity of the cylinder 3 21 decreases, the piston shaft 23 gradually descends, thereby driving the rack 39 to descend, thereby driving the spray angle of the cylinder 32 from the center of the stone to the two sides of the stone. When the spraying is about to end, the cylinder 32 sprays the water onto the inclined plate 47, and the water flows along the inclined plate 47 onto the through-hole plate 1 45 and the through-hole plate 2 46, flushing the through-hole plate 1 45 and the through-hole plate 2 46.

[0048] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
