DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

The side wall of the rotating frame 3 is fixedly connected to the third motor 31, and the output shaft of the third motor 31 is fixedly connected to one end of the reciprocating screw 32; the reciprocating screw 32 is threadedly connected to a moving block 34; two guide rods 33 are fixedly connected to the rotating frame 3, and the moving block 34 is slidably connected to the two guide rods 33, and the bottom of the moving block 34 is fixedly connected to a first electric push rod 341, and the output end of the first electric push rod 341 is mounted with a laser cutting head 342 through a mounting block.

[0034] Marble is very beautiful after being polished. It is mainly used to be processed into various profiles and plates for the walls, floors, platforms and columns of buildings. It is also often used as a material for memorial buildings such as monuments, towers, statues, etc. Marble can also be carved into practical works of art such as arts and crafts, stationery, lamps, utensils, etc., and is often used in the field of building block manufacturing. Since the rotation center of the laser cutting head 342 is fixed, when cutting an arc, only the rotation range angle can be adjusted, but it cannot meet the cutting needs of different center positions and arcs, resulting in low cutting applicability of the laser cutting head 342.

[0035] When the telescopic mechanism provided by the present invention is used, firstly, the marble is placed on the base 1, and then when cutting the marble, it usually includes cutting arcs of different arcs at different positions and cutting arcs of different arcs at the same position; when cutting arcs of different arcs at different positions, it is necessary to turn on the first motor 24, and the output shaft of the first motor 24 drives the gear 25 to rotate, and the gear 25 drives the rack 23 to move, and the rack 23 drives the telescopic plate 22 to move until the telescopic plate 22 moves to a suitable position, realizing the replacement of the center of the cutting arc, which is suitable for the function of cutting arcs of different positions; when cutting arcs of different arcs at the same position, by adjusting the position of the telescopic plate 22, and then Turn on the third motor 31, and the reciprocating screw 32 is driven to rotate by the output shaft of the third motor 31, and the moving block 34 is driven to move by the reciprocating screw 32, and the first electric push rod 341 and the laser cutting head 342 are driven to move by the moving block 34 until they move to a suitable position, that is, the cutting radius of the cutting arc is adjusted; during the movement of the moving block 34, the moving block 34 slides on the guide rod 33, and the guide rod 33 limits the moving block 34 to move in the horizontal direction; then turn on the laser cutting head 342 for cutting; during cutting, turn on the second motor 26, and the output shaft of the second motor 26 drives the rotating frame 3 to rotate, and the rotating frame 3 drives the laser cutting head 342 to rotate, so as to realize the cutting process of the marble.

[0036] In addition, linear cutting will also be encountered during the arc cutting process. At this time, it is necessary to drive the reciprocating screw rod 32 to rotate according to the length or width of the marble to adjust the cutting length; then, by turning on the first motor 24, the telescopic plate 22 drives the rotating frame 3 and the laser cutting head 342 to move linearly to perform linear cutting.

[0037] like Figure 5As shown, two first vertical rods 343 are fixed to the top of the mounting block; the output end of the first electric push rod 341 is symmetrically fixed to two first side plates 344; the first vertical rods 343 are respectively slidably connected to the first side plates 344; a drain pipe 35 is sleeved on one side of the mounting block through a fixed block, and one end of the drain pipe 35 close to the laser cutting head 342 is rotatably connected to the rotating nozzle 351; a connector 352 is fixed to the bottom of the rotating frame 3 opposite to the center of the second motor 26, and one end of the drain pipe 35 is rotatably connected to the connector 352; a drainage mechanism is provided on one side of the connector 352.

[0038] When the rotating nozzle 351 provided by the present invention is in use, the mounting block is driven to move by the first electric push rod 341. During the movement of the mounting block, the mounting block drives the first vertical rod 343 to move. The first vertical rod 343 slides on the first side plate 344, and the mounting block and the laser cutting head 342 are limited to move in the vertical direction by the first vertical rod 343; and when the mounting block moves, the drainage pipe 35 is driven to move by the fixed block, and the rotating nozzle 351 is driven to move by the drainage pipe 35. The laser cutting head 342 is sprayed by the rotating nozzle 351, which can achieve the functions of dust reduction and temperature reduction; wherein the drainage pipe 35 is a telescopic pipe, and the length can be adjusted by arbitrarily twisting.

[0039] like Figure 5 As shown, a second electric push rod is fixedly connected to the bottom of one end of the rotating frame 3 close to the second motor 26, a round block is fixedly connected to the output end of the second electric push rod, and a pressure block 361 is rotatably connected to the bottom of the round block; two second vertical rods 362 are fixedly connected to the top of the round block, and two second side plates 363 are symmetrically fixed to the side walls of the second electric push rod, and the second vertical rods 362 are respectively slidably connected to the two second side plates 363.

[0040] When the pressing block 361 provided by the present invention is in use, it is necessary to press the top of the marble through the pressing block 361 during cutting to prevent it from deflecting during cutting. By turning on the second electric push rod, the round block is driven to move through the output end of the second electric push rod, and the pressing block 361 is driven to move through the round block until the pressing block 361 is pressed on the top of the marble. The pressing block 361 is arranged directly below the center of the second motor 26, and no torque is generated during the rotation process. During the movement of the round block, the round block drives the second vertical rod 362 to slide on the second side plate 363, and the pressing block 361 and the round block are limited to move in the vertical direction through the second vertical rod 362.

[0041] like Figure 1 and Figure 2 As shown, a cavity is provided inside the base 1, and a fence 12 is fixed around the top of the base 1; a plurality of filter holes 11 are provided on the top of the base 1; an inclined block 15 is fixed on the bottom inner wall of the cavity; and a fixing mechanism is provided on the base 1.

[0042] The fence 12 provided by the present invention is used to prevent water from overflowing and cutting debris from splashing on the outside of the base 1 when in use; by providing the filter hole 11, during cutting, the cutting debris flows into the cavity along with the water through the filter hole 11, and flows from the inclined block 15 to the filter basket 16, and then the water and cutting debris are separated; by providing a fixing mechanism on the base 1, it is used to fix the marble to prevent deviation during cutting.

[0043] like Figure 2 and Figure 7 As shown, the fixing mechanism includes a fourth motor 47 fixed to the top of the inclined block 15, and a forward and reverse screw rod 46 is fixed to the output shaft of the fourth motor 47, and the top of the forward and reverse screw rod 46 is rotatably connected to the top inner wall of the cavity through a bearing; the forward and reverse screw rod 46 is threadedly connected to a lifting block 45, and four connecting rods 44 are rotatably connected to the outer wall of the lifting block 45 through a pin shaft, and the top of the connecting rod 44 is rotatably connected to a slider 42 through a pin shaft, and the top of the slider 42 is rotatably connected to the limiting column 41 through a bearing; the outer side of the fourth motor 47 is sleeved with a sleeve 48.

[0044] When the fixing mechanism provided by the present invention is in use and the marble needs to be fixed, the fourth motor 47 is turned on, and the positive and negative screw rods 46 are driven to rotate by the output shaft of the fourth motor 47, and the lifting block 45 is driven to move by the positive and negative screw rods 46. During the up and down movement of the lifting block 45, one end of the connecting rod 44 is driven to move by the lifting block 45. During the movement of the connecting rod 44, it rotates under the action of the pin shaft, and the other end of the connecting rod 44 drives the slider 42 to slide, and drives the limiting column 41 to move through the slider 42. When the lifting block 45 moves upward, the limiting column 41 moves outward at the same time with the positive and negative screw rods 46 as the center of the circle; when the lifting block 45 moves downward, the limiting column 41 moves inward at the same time with the positive and negative screw rods 46 as the center of the circle, thereby achieving the fixation of the marble; and if the marble is round or square, it can be placed directly in the middle of the limiting column 41. When the marble is rectangular, it can be placed tilted in the limiting column 41, where the two limiting columns 41 are respectively arranged on the two long sides of the rectangle.

[0045] like Figure 1 As shown, four sliding openings 4 are opened on the top of the base 1 , and the sliders 42 are slidably connected in the four sliding openings 4 respectively. A pad 43 is fixed on the top of the base 1 , and the height of the pad 43 is consistent with the height of the slider 42 .

[0046] When the sliding opening 4 provided by the present invention is in use, the slider 42 slides, and the sliding block slides in the sliding opening 4. The sliding opening 4 limits the slider 42 to contract or expand in the horizontal direction. The height of the pad 43 is consistent with the height of the slider 42, which is convenient for providing support for the middle part of the marble.

[0047] like Figure 1 、 Figure 2 and Figure 6 As shown, the drainage mechanism includes a water tank 13 fixedly connected to the bottom of the base 1, and a water pipe 14 is connected and fixed to the side wall of the water tank 13, and a water pump is installed on the water pipe 14; a connecting cylinder 353 is rotatably connected between the rotating frame 3 and the telescopic plate 22, and the connecting cylinder 353 is arranged on the outside of the connecting head 352; one end of the water pipe 14 is connected and fixed to the connecting cylinder 353, and a plurality of water holes are opened on the top of the connecting head 352.

[0048] When the drainage mechanism provided by the present invention is in use and drainage is required, the water in the water tank 13 is transported through the water pipe 14 by a water pump, and the water in the water pipe 14 enters the connecting cylinder 353. The water in the connecting cylinder 353 flows into the connecting head 352 through the water hole, and then flows through the drainage pipe 35. The water in the drainage pipe 35 is sprayed out through the rotating nozzle 351 to reduce dust on the cutting debris and cool the laser cutting head 342.

[0049] like Figure 2 and Figure 9 As shown, a discharge port is provided at the lower end of the inclined block 15, and a filter basket 16 is provided in the discharge port, and the filter basket 16 is slidably connected to the water tank 13; a plurality of springs 162 are fixedly connected to the bottom inner wall of the filter basket 16, and a sieve plate 161 is fixedly connected to the top of the plurality of springs 162, and the sieve plate 161 is slidably connected to the inner wall of the filter basket 16; two clamping columns 163 are symmetrically fixed to the outer wall of the filter basket 16; two clamping blocks 164 are rotatably connected to the outer wall of the water tank 13, and the clamping blocks 164 are respectively clamped on the clamping columns 163.

[0050] When the sieve plate 161 provided by the present invention is in use, the cutting debris flows with the water through the filter hole 11 and flows into the cavity, and then flows into the filter basket 16 along the inclined block 15. During the flow process, the cutting debris and water flow first flow through the sieve plate 161. Under the action of pressure and spring 162, the sieve plate 161 will shake, and the water on the sieve plate 161 will quickly pass through the sieve plate 161 and flow into the filter basket 16, and finally flow into the water tank 13 for water recycling; when the cutting debris in the filter basket 16 accumulates for a period of time, it is necessary to release the connection between the clamping column 163 and the clamping block 164, take out the filter basket 16, and pour out the cutting debris inside.

[0051] like Figure 8 As shown, a base plate 5 is fixedly connected to the inner wall of the cavity, a third electric push rod 51 is fixedly connected to the top of the base plate 5, and a cleaning brush 52 is fixedly connected to the output end of the third electric push rod 51. The cleaning brush 52 is arranged on one side of the positive and negative threaded rod 46.

[0052] When the cleaning brush 52 provided by the present invention is in use, the positive and negative threaded rods 46 work for a period of time, and cutting debris may be attached to the surface. If the debris is not cleaned, it may get stuck at the connection between the lifting block 45 and the positive and negative threaded rods 46, affecting the threaded fit of the lifting block 45 and the positive and negative threaded rods 46, resulting in poor precision of the positive and negative threaded rods 46, and the lifting block 45 cannot move to the set position, thereby causing the limit column 41 to be unable to fix the marble well, so it is necessary to turn on the third electric push rod 51, and drive the cleaning brush 52 to move through the output end of the third electric push rod 51 until the cleaning brush 52 moves to one side of the positive and negative threaded rods 46. Then, during the rotation of the positive and negative threaded rods 46, the cleaning brush 52 cleans the cutting debris on the surface of the positive and negative threaded rods 46, thereby realizing the cleaning function of the positive and negative threaded rods 46.

[0053] like Figure 8 As shown, a protective cover 53 is fixedly connected to the side wall of the cleaning brush 52, and a rectangular block is fixedly connected to the bottom of the protective cover 53; a sliding rod 54 is fixedly connected to the side wall of the third electric push rod 51, and the rectangular block is slidably connected to the sliding rod 54.

[0054] When the protective cover 53 provided by the present invention is in use, the cleaning brush 52 is driven to move by the output end of the third electric push rod 51, and the protective cover 53 is driven to move by the cleaning brush 52, and the rectangular block is driven to move by the protective cover 53, and the rectangular block slides on the slide rod 54, wherein the protective cover 53 covers the top of the output end of the third electric push rod 51 to prevent cutting debris and water from falling on the output end of the third electric push rod 51 and causing damage to the third electric push rod 51.

[0055] Working principle: First, place the marble on the base 1, turn on the fourth motor 47, and drive the positive and negative screw rods 46 to rotate through the output shaft of the fourth motor 47, and drive the lifting block 45 to move through the positive and negative screw rods 46. During the up and down movement of the lifting block 45, one end of the connecting rod 44 is driven to move through the lifting block 45. During the movement of the connecting rod 44, it rotates under the action of the pin shaft, and the other end of the connecting rod 44 drives the slider 42 to slide, and drives the limiting column 41 to move through the slider 42. When the lifting block 45 moves upward, the limiting column 41 moves outward at the same time with the positive and negative screw rods 46 as the center of the circle; when the lifting block 45 moves downward, the limiting column 41 moves inward at the same time with the positive and negative screw rods 46 as the center of the circle, thereby fixing the marble; and if the marble is round or square, it can be placed directly in the middle of the limiting column 41. When the marble is rectangular, it can be placed tilted in the limiting column 41, where the two limiting columns 41 are respectively arranged on the two long sides of the rectangle. Then, by turning on the second electric push rod, the round block is driven to move through the output end of the second electric push rod, and the pressing block 361 is driven to move through the round block until the pressing block 361 is pressed on the top of the marble, and the pressing block 361 is located directly below the center of the second motor 26 to prevent deviation during cutting.

[0056] Then, when cutting marble, it usually includes cutting arcs of different radians at different positions and cutting arcs of different radians at the same position; when cutting arcs of different radians at different positions, it is necessary to turn on the first motor 24, and drive the gear 25 to rotate through the output shaft of the first motor 24, and drive the rack 23 to move through the gear 25, and drive the telescopic plate 22 to move through the rack 23 until the telescopic plate 22 moves to a suitable position, thereby realizing the replacement of the center of the cutting arc, which is suitable for cutting arcs of different positions; when cutting arcs of different radians at the same position, by adjusting the position of the telescopic plate 22, and then turning on the third motor 31, the telescopic plate 22 is rotated to the right position. The output shaft of 31 drives the reciprocating screw 32 to rotate, and the reciprocating screw 32 drives the moving block 34 to move, and the moving block 34 drives the first electric push rod 341 and the laser cutting head 342 to move until they move to a suitable position, that is, the cutting radius of the cutting arc is adjusted; during the movement of the moving block 34, the moving block 34 slides on the guide rod 33, and the guide rod 33 limits the moving block 34 to move in the horizontal direction; then the laser cutting head 342 is turned on for cutting; during cutting, the second motor 26 is turned on, and the output shaft of the second motor 26 drives the rotating frame 3 to rotate, and the rotating frame 3 drives the laser cutting head 342 to rotate, so as to realize the cutting process of marble.

[0057] The water in the water tank 13 is transported through the water pipe 14 by a water pump. The water in the water pipe 14 enters the connecting tube 353. The water in the connecting tube 353 flows into the connecting head 352 through the water hole, and then flows through the drain pipe 35. The water in the drain pipe 35 is sprayed out through the rotating nozzle 351 to reduce dust on the cutting debris and cool the laser cutting head 342. The cutting debris flows through the filter hole 11 with the water and flows into the cavity, and then flows into the filter basket 16 along the inclined block 15. During the flow process, the cutting debris and water flow first flow through the sieve plate 161. Under the action of pressure and spring 162, the sieve plate 161 will shake, and the water on the sieve plate 161 will quickly pass through the sieve plate 161 and flow into the filter basket 16, and finally flow into the water tank 13 for water recycling. When the cutting debris in the filter basket 16 accumulates for a period of time, it is necessary to release the connection between the clamping column 163 and the clamping block 164, take out the filter basket 16, and pour out the cutting debris inside.

[0058] After the positive and negative threaded screws 46 have been working for a period of time, there may be cutting debris attached to the surface. If the debris is not cleaned, it may get stuck at the connection between the lifting block 45 and the positive and negative threaded screws 46, affecting the threaded fit of the lifting block 45 and the positive and negative threaded screws 46, resulting in poor precision of the positive and negative threaded screws 46, and the lifting block 45 cannot move to the set position, which causes the limit column 41 to be unable to fix the marble well. Therefore, it is necessary to turn on the third electric push rod 51, and drive the cleaning brush 52 to move through the output end of the third electric push rod 51 until the cleaning brush 52 moves to one side of the positive and negative threaded screws 46. Then, during the rotation of the positive and negative threaded screws 46, the cleaning brush 52 cleans the cutting debris on the surface of the positive and negative threaded screws 46, thereby realizing the cleaning function of the positive and negative threaded screws 46. When the cleaning brush 52 is driven to move by the output end of the third electric push rod 51, the cleaning brush 52 drives the protective cover 53 to move, and the protective cover 53 drives the rectangular block to move. The rectangular block slides on the slide rod 54, wherein the protective cover 53 covers the top of the output end of the third electric push rod 51 to prevent cutting debris and water from falling on the output end of the third electric push rod 51 and causing damage to the third electric push rod 51.
