Description

Technical Field

[0002] Quartz stone, what we usually call quartz stone is a new type of stone artificially synthesized from more than 90% quartz crystals plus resin and other trace elements. Quartz stone has a wide range of uses and can be used in construction, home furnishing, decoration and other fields. During the processing of quartz stone slabs, due to the different sizes and shapes of quartz stone slabs used in different places, the quartz stone slabs need to be cut.

[0003] In the process of cutting quartz stone slabs, the commonly used cutting method is to use a saw blade for cutting. With continuous cutting, the cutting speed is too fast or the feed rate is too large, which may cause the friction between the saw blade and the material to intensify, heat accumulation, and thus the saw blade to get stuck. Insufficient cooling during the cutting process, such as insufficient cooling water supply or poor coolant lubrication effect, may also cause the saw blade to overheat and get stuck. After the saw blade gets stuck, the staff is unaware of it, and the propulsion equipment will continue to advance, causing the saw blade to break and be damaged, causing certain safety hazards. For this reason, a quartz stone slab cutting device is proposed. Summary of the Invention

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] As introduced in the background technology, there are deficiencies in the existing technology. In order to solve the above technical problems, this application proposes a quartz stone slab cutting device.

[0036] In a typical embodiment of the present application, Figure 1 and Figure 3As shown, a quartz stone plate cutting device includes:

[0037] A processing platform 1, a plate body 2 is placed on the processing platform 1, and a plate pressing mechanism 13 is provided on the processing platform 1, which is used to press the placed plate body 2. The plate pressing mechanism 13 includes a U-shaped frame 14 fixedly installed on the processing platform 1, and a threaded column 15 is threadedly installed on the U-shaped frame 14. A pressing plate 16 is rotatably installed on one end of the threaded column 15, and the pressing plate 16 is pressed on the top of the plate body 2. A guide column 17 is fixedly installed on the top of the pressing plate 16, and the top of the guide column 17 is movable through the U-shaped frame 14. The plate body 2 to be cut is placed on the processing platform 1, and then the plate pressing mechanism 13 is used to press the placed plate body 2. After the threaded column 15 on the plate pressing mechanism 13 is rotated, it will drive the pressing plate 16 to move downward, thereby achieving the pressing effect of the plate body 2. The guide column 17 provided can limit the downward movement of the pressing plate 16.

[0038] As a preferred implementation in this embodiment, Figure 1 、 Figure 2 and Figure 4 As shown, the mobile mechanism 3 includes an equipment frame 4 fixedly mounted on the processing platform 1, a U-shaped screw sleeve 7 is provided on the equipment frame 4, and a mobile cutting mechanism 8 is provided on the U-shaped screw sleeve 7 for cutting the plate body 2. The mobile cutting mechanism 8 includes a rotating support rod 9 rotatably mounted on the equipment frame 4, a cutting disc 10 is rotatably mounted on the rotating support rod 9, and a protective cover 11 is provided above the cutting disc 10. The protective cover 11 is installed on the side of the rotating support rod 9. A driving motor 5 is fixedly mounted on the side of the equipment frame 4, and the output end of the driving motor 5 is connected to the rotating screw sleeve 7. Rod 6, U-shaped screw sleeve 7 is threadedly connected to the rotating screw 6, and the side of the U-shaped screw sleeve 7 is fixedly installed with a side position baffle 12. The side position baffle 12 blocks the side of the rotating support rod 9, and the cutting disc 10 on the mobile cutting mechanism 8 is started to rotate. The rotating cutting disc 10 can cut the plate body 2, and at the same time, the driving motor 5 on the moving mechanism 3 is started to run. After the driving motor 5 runs, it drives the rotating screw 6 to rotate, thereby driving the U-shaped screw sleeve 7 to move, and the cutting disc 10 will also move horizontally to realize the cutting operation of the plate body 2.

[0039] As a preferred implementation in this embodiment, Figure 1 、 Figure 5 and Figure 6As shown, a circulating cooling mechanism 18 is arranged above the processing platform 1 and is used for cooling the cutting disc 10 during the cutting process.

A water pump 23 is provided in the collecting frame 21, and a water pipe 24 is connected to the water pump 23. One end of the water pipe 24 is connected to a branch pipe 25. Both sides of the protective cover 11 are respectively connected to a water spray pipe 26 and an atomizing dust reduction pipe 27. The branch pipe 25 is respectively connected to the water spray pipe 26 and the atomizing dust reduction pipe 27. A plurality of water spray heads 28 are connected to the water spray pipe 26, and a plurality of atomizing heads 29 are connected to the atomizing dust reduction pipe 27. The water spray head 28 and the atomizing head 29 are both arranged on the inner wall of the protective cover 11.

[0040] During the cutting process, the water pump 23 on the circulating cooling mechanism 18 runs, and the coolant is pumped out through the water pipe 24 and the branch pipe 25, and finally sprayed out from the water spray head 28 and the atomizing head 29. The water spray head 28 is arranged at the front end position where the cutting disc 10 enters the protective cover 11, and can quickly spray water to cool the cutting disc 10. The atomizing head 29 is arranged at the rear half of the protective cover 11. The sprayed mist droplets follow the rotation of the disc to the lower position to humidify the plate body 2. At the same time, the dust generated by the cutting will also play a good dust reduction role under the action of the water mist. The water droplets after cooling and dust reduction will leak from the cutting leak 19 and flow along the flow box 20 to the collection frame 21 for recycling. The filter frame 22 is provided to block and filter the debris generated during the cutting process.

[0041] As a preferred implementation in this embodiment, Figure 1 、 Figure 7 and Figure 8As shown, the anti-jamming mechanism 30 is provided on the U-shaped screw sleeve 7, which is used to detect and prevent the cutting disc 10 from getting stuck 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-shaped structure. Side blocks 32 are fixedly installed on both sides of the U-shaped screw sleeve 7. The sides of the two side blocks 32 are fixedly installed with the same mounting block 33. 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. The two wedge-shaped extrusion blocks 34 are adapted to the extrusion sleeve 31. The wedge-shaped extrusion block 34 can detect and prevent the cutting disc 10 from getting stuck after being squeezed. Several mounting boxes 38 are fixedly installed on the side of the side block 32. A first magnetic block 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 magnetic block 41. The first magnetic block 39 and the second magnetic block 41 repel each other with the same polarity. A convex groove 35 is provided 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, and the convex slider 36 is slidably installed in the convex groove 35.

[0042] The cutting disc 10 is mounted on the rotating support rod 9, and the rotating support rod 9 is rotatably mounted on the U-shaped screw sleeve 7. The side position baffle 12 is set, which can block the position of the rotating support rod 9 from one side, and the rotating support rod 9 can achieve a certain angle deviation toward the other side. Through the design of the angle deviation, the problem that the cutter disc cannot move with the moving mechanism 3 after being stuck can be solved. The U-shaped screw sleeve 7 is provided with an anti-clamping mechanism 30, and the damping spring 37 on the anti-clamping mechanism 30 can provide a certain anti-rotation force. At the same time, multiple groups of first magnetic blocks 39 and second magnetic blocks 41 are set. The first magnetic block 39 and the second magnetic block 41 are like-sex magnetic blocks. According to the principle of opposite repulsion, they will also provide a strong anti-rotation force. Through a variety of anti-rotation forces, the position of the rotating support rod 9 can be maintained, which can meet the blocking force generated during the cutting process, and the rotating support rod 9 will not rotate easily.

[0043] As a preferred implementation in this embodiment, Figure 1 、 Figure 9 and Figure 10As shown, a moving block 42 is fixedly installed on the side of a wedge-shaped extrusion block 34, a triggering 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 mounting 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 triggering 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 provided on the side of the equipment frame 4, and 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 provided on the bracket 48, a pushing block 50 is fixedly installed on one side of the moving block 42, a sliding piece 51 is provided on one side of the pushing block 50, and the sliding piece 51 slides on the sliding rheostat 49.

[0044] Once the friction of the cutting disc 10 intensifies, heat accumulates, and it gets stuck, the moving mechanism 3 will continue to move. However, when the cutting disc 10 is difficult to move, the rotating support rod 9 will deflect at an angle under the condition of the stuck drag force. The rotating support rod 9 rotates to drive the extrusion sleeve 31 to move, and the movement of the extrusion sleeve 31 will squeeze the wedge-shaped extrusion blocks 34 on both sides. After the wedge-shaped extrusion blocks 34 move, they drive the moving block 42 to move, and the movement of the moving block 42 drives the trigger conductive block 43 to move. As the drag force increases, the angular deviation of the rotating support rod 9 becomes larger and larger, and 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 lights up yellow to warn the staff that there is an abnormality in the cutting machine. At the same time, the movement of the moving block 42 drives the push block 50 to move, and the movement of the push block 50 drives the slide 51 to move. After the slide 51 moves on the sliding rheostat 49, the sliding rheostat 49 is electrically connected to the water pump 23. After the slide 51 moves, it can change the resistance value. At this time, the resistance value will become smaller, the current flowing through the water pump 23 will increase, the operation of the water pump 23 will be strengthened, the speed of delivering coolant will be faster, and the cutting disc 10 will be sprayed with water to cool it down more quickly to avoid excessive temperature. By lowering the temperature of the cutter disc, the cutter disc can be prevented from being stuck.

[0045] Furthermore, in the above scheme, as the cutting process continues, the temperature of the cutting disc 10 continues to rise, and the triggered conductive block 43 will contact the second conductive block 46. At this time, the second warning light 52 will light up orange. The device is internally provided with a controller, which is a PLC controller. It controls the drive motor 5 to decelerate, thereby reducing the moving speed of the moving mechanism 3 to avoid damage to the cutting disc 10 caused by rapid advancement. At the same time, the slide 51 will continue to move, and the resistance value on the sliding rheostat 49 will continue to decrease. The power of the water pump 23 will continue to increase, and the coolant delivered will also increase, thereby cooling the cutting disc 10 more quickly to avoid getting stuck.

[0046] Furthermore, in the above scheme, after the cooling of the cutting disc 10 has no obvious effect, the moving block 42 continues to move, and when the triggering conductive block 43 comes into contact with the third conductive block 47, the third warning light 52 will light up red. At this time, the internal controller will control the driving motor 5, cutting disc 10 and other equipment to shut down as a whole, waiting for the staff to come and check, to protect the cutting disc 10 to the greatest extent and avoid unnecessary safety hazards.

[0047] Working principle of the present invention: when in use, the plate body 2 to be cut is placed on the processing platform 1, the plate pressing mechanism 13 is used to press the placed plate body 2, the coolant is added to the collecting frame 21, and the mobile cutting mechanism 8 is started. The plate body 2 can be cut by the rotating cutting disc 10, and the driving motor 5 on the moving mechanism 3 is started to run, and the cutting 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 is operated, and the aqueous solution sprayed by the water spray head 28 can quickly cool the cutting disc 10, and the mist droplets sprayed by the atomizing head 29 follow the rotation of the disc to the lower position to humidify the plate body 2. At the same time, the dust generated by the cutting will also play a good dust reduction role under the action of the water mist;

[0048] During the cutting process, when the friction of the cutting disc 10 intensifies, heat accumulates, and it becomes stuck, the rotating support rod 9 will deflect at an angle under the dragging force, and the movement of the extrusion sleeve 31 will squeeze the 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 lights up yellow to warn the staff that the cutting machine has an abnormality. At the same time, the resistance value of the sliding rheostat 49 becomes smaller, and the operation of the water pump 23 is strengthened, so that the cutting disc 10 is sprayed with water to cool down more quickly to avoid excessive heat. The temperature of the cutter disc is lowered to avoid the cutter disc from being stuck. When the conductive block 43 is triggered, it will contact the second conductive block 46. At this time, the second warning light 52 will light up orange, and the drive motor 5 will be controlled to slow down, changing the propulsion speed of the cutter disc to avoid damage to the cutting disc 10 caused by rapid propulsion. The coolant delivered by the water pump 23 continues to increase. When the conductive block 43 is triggered, it will contact the third conductive block 47. The third warning light 52 will light up red. At this time, all equipment will be shut down as a whole, waiting for staff to check, avoiding unnecessary safety hazards. Through a variety of anti-jamming measures, the cutting of the plate body 2 is protected.

[0049] It should be noted that:

[0050] The driving motor 5, cutting disc 10, damping spring 37, first magnetic block 39, second magnetic block 41, and sliding rheostat 49 proposed in this application are all existing technologies, and their specific structures, functions and usages are not described in detail in this article.

[0051] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
