Description

Quartz stone has a very wide range of uses and can be used in fields such as construction, home furnishing, and decoration. During the processing of quartz stone plates, since the sizes and shapes of quartz stone plates used in different places are different, it is necessary to cut the quartz stone plates.

[0003] During the cutting process of quartz stone plates, the commonly used cutting method is to use a saw blade for cutting. With continuous cutting, if the cutting speed is too fast or the feed rate is too large, it may lead to increased friction between the saw blade and the material and heat accumulation, thus causing the saw blade to get stuck. Or, if the cooling is insufficient during the cutting process, such as insufficient supply of cooling water or poor lubrication effect of the coolant, it will also cause the saw blade to overheat and get stuck. After the saw blade gets stuck, the staff is unaware, and the propulsion device will continue to advance, resulting in the fracture and damage of the saw blade, causing certain potential safety hazards.

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a quartz stone plate cutting device.

[0021] In a typical embodiment of the present application, as Figure 1 and Figure 3 shown, a quartz stone plate cutting device includes: Processing platform 1, on which a sheet body 2 is placed. A sheet pressing mechanism 13 is arranged on the processing platform 1 for pressing the placed sheet body 2. The sheet pressing mechanism 13 includes a U-shaped frame 14 fixedly installed on the processing platform 1. A threaded column 15 is threadedly installed on the U-shaped frame 14. One end of the threaded column 15 is rotatably installed with a pressing plate 16. The pressing plate 16 presses on the top of the sheet body 2. A guide column 17 is fixedly installed on the top of the pressing plate 16. The top end of the guide column 17 movably penetrates through the U-shaped frame 14. Place the sheet body 2 to be cut on the processing platform 1, and then use the sheet pressing mechanism 13 to press the placed sheet body 2. After the threaded column 15 on the sheet pressing mechanism 13 rotates, it will drive the pressing plate 16 to move downward, thereby realizing the pressing effect of the sheet body 2. The arranged guide column 17 can limit the position of the downward movement of the pressing plate 16.

[0022] As a preferred implementation manner in this embodiment, as Figure 1 , Figure 2 and Figure 4 shown, the moving mechanism 3 includes a device frame 4 fixedly installed on the processing platform 1. A U-shaped screw sleeve 7 is arranged on the device frame 4. A moving cutting mechanism 8 is arranged on the U-shaped screw sleeve 7 for cutting the sheet body 2. The moving cutting mechanism 8 includes a rotating support rod 9 rotatably installed on the device frame 4. A cutting tool disc 10 is rotatably installed on the rotating support rod 9. A protective cover 11 is arranged above the cutting tool disc 10. The protective cover 11 is installed on the side of the rotating support rod 9. A driving motor 5 is fixedly installed on the side of the device frame 4. The output end of the driving motor 5 is connected with a rotating screw rod 6. The U-shaped screw sleeve 7 is threadedly sleeved on the rotating screw rod 6. A side position baffle 12 is fixedly installed on the side of the U-shaped screw sleeve 7. The side position baffle 12 blocks the side of the rotating support rod 9. Start the cutting tool disc 10 on the moving cutting mechanism 8 to rotate. The rotating cutting tool disc 10 can perform cutting operations on the sheet body 2. At the same time, start the driving motor 5 on the moving mechanism 3 to operate. After the driving motor 5 operates, it drives the rotating screw rod 6 to rotate, thereby driving the U-shaped screw sleeve 7 to move, and the cutting tool disc 10 will also move horizontally to realize the cutting operation of the sheet body 2.

[0023] As a preferred implementation manner in this embodiment, as Figure 1 , Figure 5 and Figure 6As shown in the figure, the circulating cooling mechanism 18 is arranged above the processing platform 1 and is used for cooling during the cutting process of the cutting tool disc 10. The circulating cooling mechanism 18 includes a cutting leakage hole 19 opened on the processing platform 1. A flowing box 20 is arranged at the bottom of the processing platform 1. A collecting frame 21 is arranged on one side of the processing platform 1. A filtering frame 22 is placed on the top of the collecting frame 21.

Spray water connecting pipes 26 and atomizing dust reduction connecting pipes 27 are respectively connected to both sides of the protective cover 11. The branch connecting pipe 25 is respectively communicated with the spray water connecting pipe 26 and the atomizing dust reduction connecting pipe 27. A plurality of spray heads 28 are connected to the spray water connecting pipe 26. A plurality of atomizing heads 29 are connected to the atomizing dust reduction connecting pipe 27. The spray heads 28 and the atomizing heads 29 are both arranged on the inner wall of the protective cover 11.

[0024] During the cutting process, the water pump 23 on the circulating cooling mechanism 18 operates, extracts the coolant, passes it through the water delivery pipe 24 and the branch connecting pipe 25, and finally sprays it out from the spray heads 28 and the atomizing heads 29. The spray heads 28 are arranged at the front end position where the cutting tool disc 10 enters the protective cover 11, and can quickly spray water to cool down the cutting tool disc 10. The atomizing heads 29 are arranged at the rear half part position of the protective cover 11. The atomized water droplets ejected rotate to the lower position following the rotation of the tool disc, humidify the plate body 2, and at the same time, the dust generated during cutting will also play a good role in dust reduction under the action of the water mist. The water droplets after cooling and dust reduction will leak down from the cutting leakage hole 19 and flow along the flowing box 20 into the collecting frame 21 to achieve recycling. The provided filtering frame 22 blocks and filters the debris generated during the cutting process.

[0025] As a preferred implementation manner in this embodiment, as Figure 1 、 Figure 7 and Figure 8As shown in the figure, the anti-jamming mechanism 30 is arranged on the U-shaped screw rod sliding sleeve 7 and is used to detect and prevent the cutting tool disc 10 from jamming during movement. The anti-jamming mechanism 30 includes an extrusion sleeve 31 fixedly sleeved on the rotating support rod 9. The side of the extrusion sleeve 31 is arranged in an arc structure. Side blocks 32 are fixedly installed on both sides of the U-shaped screw rod sliding sleeve 7. The same mounting block 33 is fixedly installed on the sides of the two side blocks 32. A damping spring 37 is connected between the mounting block 33 and the extrusion sleeve 31. Two wedge-shaped extrusion blocks 34 are slidably installed on the side of the mounting block 33. Both of the two wedge-shaped extrusion blocks 34 are adapted to the extrusion sleeve 31. After being extruded, the wedge-shaped extrusion blocks 34 can detect and prevent the cutting tool disc 10 from jamming. A plurality of mounting boxes 38 are fixedly installed on the side of the side block 32. A first magnet 39 is fixedly installed on the inner wall of the mounting box 38. A connecting rod 40 is fixedly installed on the side of the wedge-shaped extrusion block 34. One end of the connecting rod 40 extends into the mounting box 38 and is fixedly installed with a second magnet 41. The first magnet 39 and the second magnet 41 repel each other with the same polarity. A convex chute 35 is opened on the side of the mounting block 33. A convex slider 36 is fixedly installed on the side of the wedge-shaped extrusion block 34. The convex slider 36 is slidably installed in the convex chute 35.

[0026] The cutting tool disc 10 is installed on the rotating support rod 9. The rotating support rod 9 is rotatably installed on the U-shaped screw rod sliding sleeve 7. The provided side position baffle 12 can block the position of the rotating support rod 9 from one side. The rotating support rod 9 can deviate by a certain angle towards the other side. Through the design of the angle deviation, the problem that the tool disc cannot follow the movement mechanism 3 after being jammed can be solved. The anti-jamming mechanism 30 is arranged on the U-shaped screw rod sliding sleeve 7. The damping spring 37 on the anti-jamming mechanism 30 can provide a certain anti-rotation force. At the same time, with the arrangement of multiple groups of the first magnets 39 and the second magnets 41, the first magnets 39 and the second magnets 41 are magnets with the same polarity. According to the principle of repulsion between like poles, a strong anti-rotation force will also be provided. Through various anti-rotation forces, the position of the rotating support rod 9 can be maintained, and the blocking force generated during the cutting process can be satisfied. The rotating support rod 9 will not rotate easily.

[0027] As a preferred implementation manner in this embodiment, as Figure 1 、 Figure 9 and Figure 10As shown in the figure, a moving block 42 is fixedly installed on the side of a wedge-shaped extrusion block 34. A trigger conductive block 43 is fixedly installed on the side of the moving block 42. A fixed block 44 is fixedly installed on the side of the installation block 33. A first conductive block 45, a second conductive block 46 and a third conductive block 47 are fixedly installed on the side of the fixed block 44. The trigger conductive block 43 is electrically connected to the first conductive block 45, the second conductive block 46 and the third conductive block 47 respectively. Three warning lights 52 are arranged on the side of the equipment frame 4. The three warning lights 52 are electrically connected to the first conductive block 45, the second conductive block 46 and the third conductive block 47 respectively. A bracket 48 is fixedly installed on the side of the side block 32. A sliding rheostat 49 is arranged on the bracket 48. A pushing block 50 is fixedly installed on one side of the moving block 42. A sliding piece 51 is arranged on one side of the pushing block 50. The sliding piece 51 slides on the sliding rheostat 49.

[0028] Once when the cutting tool disc 10 has increased friction, heat accumulation and gets stuck, the moving mechanism 3 will still continue to move. However, when it is difficult for the cutting tool disc 10 to move, the rotating support rod 9 will deflect at an angle under the dragging force. The rotation of the rotating support rod 9 drives the extrusion sleeve 31 to move. The movement of the extrusion sleeve 31 will squeeze the two wedge-shaped extrusion blocks 34. After the wedge-shaped extrusion blocks 34 move, they drive the moving block 42 to move. The movement of the moving block 42 drives the trigger conductive block 43 to move. As the dragging force increases, the angular deviation of the rotating support rod 9 becomes larger and larger. The trigger conductive block 43 will first contact the first conductive block 45. At this time, a warning light 52 on the equipment frame 4 will light up yellow to warn the staff that the cutting machine is abnormal. At the same time, the movement of the moving block 42 drives the pushing block 50 to move. The movement of the pushing block 50 drives the sliding piece 51 to move. After the sliding piece 51 moves on the sliding rheostat 49, the sliding rheostat 49 is electrically connected to the water pump 23. After the sliding piece 51 moves, the resistance value can be changed. At this time, the resistance value will become smaller, and the current flowing through the water pump 23 will increase. The operation of the water pump 23 is strengthened, and the speed of conveying the coolant will be faster, and the cutting tool disc 10 will be sprayed with water for cooling more quickly to avoid generating too high a temperature. By reducing the temperature of the tool disc, the situation of the tool disc being stuck is avoided.

[0029] Furthermore, in the above solution, as the cutting process continues, the temperature of the cutting tool disc 10 continues to rise. At this time, the trigger conductive block 43 will contact the second conductive block 46. At this time, the second warning light 52 will light up orange. A controller is arranged inside the equipment. The controller is a PLC controller, which controls the driving motor 5 to decelerate, thereby reducing the moving speed of the moving mechanism 3 to avoid damage to the cutting tool disc 10 caused by rapid advancement. At the same time, the sliding piece 51 will continue to move, the resistance value on the sliding rheostat 49 will continue to become smaller, and the power of the water pump 23 will continue to increase, and the conveyed coolant will also increase, so as to cool the cutting tool disc 10 more quickly and avoid getting stuck.

[0030] Further, in the above solution, after the cooling of the cutting tool disc 10 has no obvious effect, the moving block 42 continues to move. When the conductive block 43 is triggered to contact the third conductive block 47, the third warning light 52 will turn on a red light. At this time, the internal controller will control the overall shutdown of devices such as the driving motor 5 and the cutting tool disc 10, waiting for the staff to check, to protect the cutting tool disc 10 to the greatest extent and avoid unnecessary safety hazards.

[0031] Working principle of the present invention: When in use, the plate body 2 to be cut is placed on the processing platform 1, and the placed plate body 2 is pressed by the plate pressing mechanism 13. Coolant is added to the collection frame 21, and the moving cutting mechanism 8 is started. The rotating cutting tool disc 10 can perform cutting operations on the plate body 2. At the same time, the driving motor 5 on the moving mechanism 3 is started to run, and the cutting tool disc 10 moves horizontally to realize the cutting operation of the plate body 2. During the cutting process, the water pump 23 on the circulating cooling mechanism 18 runs, and the aqueous solution sprayed by the water spray head 28 can quickly cool down the cutting tool disc 10. The misty water droplets sprayed by the atomizing head 29 rotate to the lower position following the rotation of the tool disc, humidifying the plate body 2. At the same time, the dust generated by cutting will also play a good role in dust reduction under the action of the water mist; During the cutting process, when the cutting tool disc 10 has increased friction, heat accumulation, and gets stuck, the rotating support rod 9 will deflect at an angle under the dragging force. The moving extrusion sleeve 31 will squeeze the two wedge-shaped extrusion blocks 34 on both sides and drive the trigger conductive block 43 to move. As the dragging force increases, the trigger conductive block 43 will first contact the first conductive block 45. At this time, a warning light 52 on the equipment frame 4 will turn on a yellow light to warn the staff that the cutting machine is abnormal. At the same time, the resistance value of the sliding rheostat 49 becomes smaller, and the water pump 23 runs stronger to spray water and cool down the cutting tool disc 10 more quickly, avoiding the generation of too high a temperature. By reducing the temperature of the tool disc, the situation of the tool disc getting stuck is avoided. When the trigger conductive block 43 will contact the second conductive block 46, the second warning light 52 will turn on orange, controlling the driving motor 5 to decelerate and changing the advancing speed of the tool disc to avoid damage to the cutting tool disc 10 caused by rapid advancement. The coolant conveyed by the water pump 23 continues to increase. When the trigger conductive block 43 will contact the third conductive block 47, the third warning light 52 will turn on a red light. At this time, all devices are shut down as a whole, waiting for the staff to check, avoiding unnecessary safety hazards. Through various anti-jamming measures, it escorts the cutting of the plate body 2.

[0032] It should be noted that: In this application, the drive motor 5, the cutting tool disc 10, the damping spring 37, the first magnet 39, the second magnet 41, and the sliding rheostat 49 are all prior arts. Their specific structures, functions, and usage methods will not be elaborated in this text.

[0033] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
