Description

Technical Field

[0001] The invention relates to the technical field of building material processing devices, in particular to a building material cutting device for building construction. Background Art

[0002] In the construction of housing projects, building material cutting is an extremely critical link. Early building material cutting devices were mostly manually operated, which not only consumed manpower, but also had extremely low cutting efficiency, greatly slowing down the construction progress. With the expansion of construction scale and the refinement of technology, the accuracy of traditional devices is difficult to meet the needs, and cutting errors often lead to waste of building materials. At the same time, old equipment has serious noise and dust pollution, which does not conform to the current green construction concept. Therefore, most of the cutting operations on the market today use automatic processing equipment.

[0003] When cutting stone, the existing building material cutting device relies on a multi-axis processing table to drive the cutting device to operate the stone below to process the stone into the actual required size, but this type of device has many problems:

[0004] 1. Poor quality of cutting seams: Frequent chipping occurs during the cutting process, resulting in a large number of defects in the cutting seams, which seriously affects the appearance quality and yield rate of the stone.

[0005] 2. Serious waste of water-abrasive liquid: During the stone cutting process, although the water-abrasive liquid is sprayed onto the cutting disc and the stone cutting seam to achieve the purpose of cooling and dust removal, the existing method of spraying the water-abrasive liquid onto the cutting disc has obvious defects. Due to the strong centrifugal force generated by the high-speed rotation of the cutting disc, a large amount of water-abrasive liquid is quickly thrown away as soon as it touches the cutting disc, and is lost in vain before it can fully play its role. The waste problem is very prominent. This not only greatly reduces the actual efficiency of cooling and dust removal, making it difficult to meet the requirements of heat dissipation and dust reduction during stone cutting, but also greatly increases the cost of use.

[0006] 3. Dust hazards: A lot of dust will be generated in the protective cover during cutting. Although some of the dust can be dissolved by the water-abrasive fluid, some of it still adheres to the inner wall of the protective cover, seriously affecting the performance of the equipment.

[0007] Therefore, in order to improve the stone cutting effect, the present invention provides a building material cutting device for building construction. Summary of the invention

The two adjacent water guide plates in each group of water guide plates are slightly inclined toward the inner wall of the protective cover on the opposite side, and are alternately installed on the side walls on both sides of the protective cover, and the concave surface is aligned with the corresponding cutting disk.

If the two cutting discs rotate in the opposite direction to that just now, the vortex forms a bottom-up flow path, and the bell-mouth structure converges and compresses the airflow, greatly increasing the flow rate of the airflow through the vents, thereby using the upward vortex to blow away dust and debris on the vents, maintaining good air circulation inside the equipment.

[0039] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below in conjunction with specific implementation methods and drawings.

[0040] The terms used in the present invention are those general terms currently widely used in the art in consideration of the functions of the present invention, but these terms may vary according to the intention of a person of ordinary skill in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in this case, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as a general description based on the meaning of the terms and the present invention.

[0041] Reference Figure 1 , Figure 2 and Figure 4 The present embodiment provides a building material cutting device for building construction, including a multi-axis CNC machining table 1, a cutting mechanism 2, a water grinding mechanism 3, a wastewater recovery mechanism 4 and an air cooling mechanism 5. The multi-axis CNC machining table 1 can simultaneously control the linkage of more than four coordinate axes. The multi-axis CNC machining table 1 includes a mounting frame 11 fixed at the bottom of the machining end, the cutting mechanism 2 is mounted at the bottom of the mounting frame 11, the cutting mechanism 2 includes a protective cover 21 fixed to the outside of the mounting frame 11, the water grinding mechanism 3 is installed on the side walls on both sides of the protective cover 21, the wastewater recovery mechanism 4 is installed inside the protective cover 21, and the air cooling mechanism 5 is detachably installed on the top shell of the protective cover 21. The multi-axis CNC machining table 1 is used to drive the mounting frame 11 to move in a multi-axial direction.

[0042] In use, the multi-axis CNC machining table 1 adopts the multi-axial mobile platform structure commonly seen in the industry, and has precise and flexible mobile characteristics, which can meet complex machining requirements. At its bottom, it is equipped with a conveying roller group, which is composed of a plurality of closely arranged and smoothly rotating rollers. The roller surface has been specially treated to have good friction, ensuring that the stone is smooth and slip-free during transportation. Before the stone cutting process, the conveying roller group can quickly and accurately transfer the stone to be processed to the designated cutting position; after the cutting process is completed, the finished stone can be transported out in time, which greatly improves the overall efficiency of stone processing and realizes the automation and efficient connection of the stone cutting process.

[0043] Reference Figure 2-Figure 4 The cutting mechanism 2 includes a protective cover 21 fixed to the outside of the mounting frame 11, and a first cutting disc 22 and a second cutting disc 23 are rotatably connected inside the protective cover 21. The cutting mechanism 2 is used for cutting and grinding stone.

[0044] Reference Figure 2 , Figure 3 and Fig.10 The water mill mechanism 3 includes four groups of nozzles 31 arranged outside the protective cover 21. The four groups of nozzles 31 are symmetrically distributed, and two groups of two are respectively aimed at the disk walls on both sides of the first cutting disk 22 and the second cutting disk 23.

[0045] Reference Figure 4 , Figure 5 and Fig.10 The waste water recovery mechanism 4 is used to collect the waste water grinding liquid which is sprayed from the nozzle 31 to the high-speed rotating cutting disc and splashed upward to the inner wall of the protective cover 21 due to the centrifugal force.

[0046] Reference Figure 4 and Figure 5 The air cooling mechanism 5 is used to construct an air circulation channel for allowing external air to flow into the protective cover 21.

[0047] Reference Figure 4and Figure 5 The first cutting disc 22 is slightly larger than the second cutting disc 23, and the center heights of the first cutting disc 22 and the second cutting disc 23 are consistent.

[0048] During use, the stone is smoothly conveyed to the bottom of the cutting mechanism 2 by the conveying roller group. The cutting mechanism 2 uses the first cutting disc 22 and the second cutting disc 23 to work together to cut the stone below. The second cutting disc 23 first cuts the hard enamel layer on the surface of the stone, and accurately cuts a shallow cutting seam. The shallower cutting depth can reduce the impact force on the stone during the initial cutting, reduce the possibility of cracking on the stone surface due to stress concentration, and guide the cutting direction of the first cutting disc 22. Subsequently, the first cutting disc 22 continues to go deeper along the cutting seam until the stone is completely cut off.

[0049] Therefore, the use of double-knife cutting method significantly improves the cutting efficiency. Compared with a single knife, the cutting task can be completed in a shorter time. At the same time, the double knives cooperate with each other to accurately control the cutting path, greatly improving the cutting accuracy and making the cutting surface smoother. Moreover, the double knives apply force evenly, making the stone more stable during the cutting process and effectively avoiding shaking or deviation. In addition, by changing the cutting path and the cutting depth of the tool, the stress on the stone is evenly distributed, which can effectively reduce the edge collapse of the stone and greatly improve the quality and yield of stone cutting.

[0050] When the cutting operation is carried out synchronously, the four groups of nozzles 31 spray water-abrasive liquid onto the cutting disc and the stone to be processed. The water-abrasive liquid can not only cool the cutting disc and the stone, effectively take away the large amount of heat generated during the cutting process, prevent the cutting disc from being damaged due to overheating, and avoid cracks in the stone due to thermal stress; it can also play a lubricating role during cutting, reduce cutting resistance, and make the cutting process smoother; it can also wash away cutting debris to ensure a clean cutting environment.

[0051] The water-grinding liquid sprayed at high speed by the nozzle 31 is accurately sprayed onto the two cutting discs. Due to the strong centrifugal force generated by the high-speed rotation of the cutting disc, the water-grinding liquid is driven to splash upward and hit the inner wall of the protective cover 21. At this time, the wastewater recovery mechanism 4 plays a role, intercepts and recovers the splashing water, and re-transports it to the cutting disc below. This design reduces the waste of water-grinding liquid and optimizes the transportation path, so that the water-grinding liquid can be transported from the top to the cutting disc below, increasing the contact area between the water-grinding liquid and the cutting disc. It can not only cool the cutting disc more effectively and extend the service life of the cutting disc, but also buffer the impact force at the moment of cutting, reduce the brittleness of the stone, and enhance the toughness of the stone. At the same time, it plays a good role in lubricating the cutting interface and reduces the occurrence of edge collapse in all directions.

[0052] In addition, the water-grinding liquid transported from top to bottom is broken up again by the high-speed rotating cutting disc and ejected outward to hit the inner wall of the protective cover 21, thus having a certain flushing function, which can continuously flush the debris generated by cutting inside the protective cover 21 and keep the interior clean.

[0053] Furthermore, when the first cutting disc 22 rotates clockwise and the second cutting disc 23 rotates counterclockwise (based on the actual rotation direction), a downward output vortex is formed when the two rotate. Combined with the air circulation channel set on the top of the protective cover 21, a top-down airflow is generated inside the protective cover 21. This airflow can blow the dust and debris generated during the cutting process out of the protective cover 21, reduce the accumulation of dust inside the equipment, reduce the risk of equipment wear, and eliminate potential safety hazards.

[0054] Reference Figure 2-Figure 5 A driving module 24 is arranged on the mounting frame 11, and an output end of the driving module 24 is connected to the first cutting disc 22. A reverse coordination component 25 is arranged inside the protective cover 21, and the reverse coordination component 25 is used to synchronize the rotational movement of the first cutting disc 22 to the second cutting disc 23 in reverse.

[0055] Reference Figure 4 and Figure 5 The reverse cooperative component 25 includes a rotating shaft 251 arranged on the inner wall of the protective cover 21, and the rotating shaft 251 is located between the first cutting disk 22 and the second cutting disk 23. A synchronous wheel 252 is provided on the first cutting disk 22 and the rotating shaft 251, and the two synchronous wheels 252 are connected to a synchronous belt 253. A gear 254 is also provided on the second cutting disk 23 and the rotating shaft 251, and the two gears 254 are meshed and connected with each other.

[0056] During use, the drive module 24 is started, driving the first cutting disk 22 to rotate at high speed. The power of the first cutting disk 22 is stably transmitted to the rotating shaft 251 through two synchronous wheels 252 and the synchronous belt 253, so that the rotating shaft 251 and the first cutting disk 22 can rotate synchronously. The gear 254 on the rotating shaft 251 is meshed with the gear 254 on the second cutting disk 23 to reverse the rotation direction transmitted by the first cutting disk 22, so that the second cutting disk 23 and the first cutting disk 22 are in the opposite motion state. The two cutting disks rotate in opposite directions and cut the stone downward. This reverse cutting method can make the cutting force act on the stone more evenly, effectively improving the cutting efficiency and cutting quality.

[0057] Reference Figure 4-Figure 6The wastewater recovery mechanism 4 includes two groups of water guide plates 41 installed on both sides of the inner wall of the protective cover 21. The two groups of water guide plates 41 are centered on the two cutting disks, fit the outer contour of the cutting disks, form a coverage area of ​​about 90 degrees, and are closely arranged in an arc shape. The two adjacent water guide plates 41 in each group of water guide plates 41 are slightly inclined toward the inner wall of the protective cover 21 on the opposite side, and are alternately installed on the side walls on both sides of the protective cover 21, and the concave surface is aligned with the corresponding cutting disk.

[0058] Reference Figure 5-Figure 7 The wastewater recovery mechanism 4 also includes a guide plate 42 arranged on the outside of the water guide plate 41. The guide plate 42 is designed to be an arc-shaped plate structure of approximately a quarter of a circle, corresponding to the water guide plate 41. The concave and convex surfaces on both sides of the guide plate 42 are provided with guide grooves 421 parallel to each other. The guide grooves 421 on the concave and convex surfaces of the guide plate 42 are staggered with each other, and a large number of water-permeable holes 422 that penetrate each other are provided in the guide grooves 421 on the concave and convex surfaces.

[0059] Reference Figure 6 , Figure 7 , Figure 8 and Fig.11 A return column 43 is provided at the top end of the guide plate 42, and the return column 43 and the multiple guide grooves 421 on the inner concave surface of the guide plate 42 are tightly fitted to form a seamless guide path; a return water channel 431 is opened on the top of the return column 43, and the top water inlet of the return water channel 431 is tightly attached to the multiple guide grooves 421 on the outer convex surface of the guide plate 42, and a confluence notch 432 matched with the guide groove 421 is opened at the junction of the water inlet.

[0060] During use, the two counter-rotating cutting discs play multiple roles during high-speed operation. They act like powerful water-throwing devices, driving the water-grinding liquid to splash upward to the top of the protective cover 21, and are accurately intercepted and recovered by the wastewater recovery mechanism 4. The entire process does not require an additional power source, and fully utilizes the rotational power of the cutting disc itself, realizing the recycling of the water-grinding liquid, which is both environmentally friendly and energy-saving.

[0061] The strong centrifugal force generated by the high-speed rotation of the cutting disk will splash the water-abrasive liquid upward with different kinetic energies. At this time, the water guide plate 41 plays a primary interception role. For the water-abrasive liquid with weaker kinetic energy, the water guide plates 41 at different positions can effectively intercept and converge it, so that it can drip and contact the cutting disk on the horizontal plane below from multiple directions, which greatly increases the contact area between the water-abrasive liquid and the cutting disk, and provides a basic guarantee for the cooling and lubrication of the cutting disk.

[0062] The abrasive liquid with strong kinetic energy that breaks through the water guide plate 41 will be taken over by the guide plate 42. The guide plate 42 is an arc-shaped plate structure with a concave inner surface and a convex outer surface. Guide grooves 421 are provided on both the inner and outer sides, which are specially used to gather and intercept these high-speed splashing abrasive liquids. When the abrasive liquid flows upward along the guide groove 421 relying on the kinetic potential energy of the flying, when it encounters the reflux column 43, its flow path is changed. The lower columnar body of the reflux column 43 guides the abrasive liquid to drip downward, so that it falls on the cutting disk, further enhancing the contact area with the cutting disk and the cooling effect.

[0063] When the amount of abrasive liquid splashing upward increases sharply, the abrasive liquid retained on the inner concave surface of the guide plate 42 will penetrate into the guide groove 421 on the outer convex surface through the water permeable holes 422, and the abrasive liquid that penetrates outward is transferred from the guide groove 421 on the outer convex surface to the confluence notch 432 opened in the reflux column 43. Subsequently, the abrasive liquid is continuously transported to the cutting disk below with the help of the conveying channels on both sides of the reflux column 43, ensuring efficient and orderly distribution when the abrasive liquid supply is sufficient.

[0064] This multi-path diversion system design optimizes the path of the water-abrasive liquid to the cutting disk, increases the contact area between the water-abrasive liquid and the cutting disk in various ways, reduces unnecessary loss of the water-abrasive liquid, and thus provides sufficient buffering, protection and cooling effects, effectively reducing the occurrence of cutting seam collapse. At the same time, the designed multi-path diversion system can fully recycle the originally discarded water-abrasive liquid, which is both environmentally friendly and energy-saving.

[0065] In addition, the reflux column 43 is flexible in design and can adopt various structural forms such as continuous tooth shape, column shape, rectangle, rhombus shape and trapezoid shape. Different structures can optimize the guiding and conveying effect of the water-grinding liquid according to specific cutting process requirements, water flow characteristics and equipment operating environment, further improving the adaptability and functionality of the entire multi-path diversion system.

[0066] Reference Figure 2-Figure 5 The air cooling mechanism 5 includes a top cover 51 arranged on the top shell of the protective cover 21, and a large number of equidistant ventilation holes 511 are opened on the top cover 51.

[0067] Reference Figure 4-Figure 5 Four groups of air guide plates 52 are arranged on the inner wall of the protective cover 21 at the bottom of the top cover 51. The four groups of air guide plates 52 are arranged at a specific angle to each other to jointly construct a structure shaped like a bell mouth, and the narrow part of the bell mouth faces the top cover 51.

[0068] Reference Figure 4-Figure 5 The top cover 51 and the outer shell of the protective cover 21 on one side close to the top cover 51 are both provided with threaded holes 53 that match each other, and a bolt 54 is installed in the two threaded holes 53 that match each other.

[0069] During use, the powerful vortices generated by the counter-rotating of the two cutting discs form a unique airflow environment inside the protective cover 21. This airflow provides power for the air to be transported downward from the top ventilation holes 511 to the bottom of the protective cover 21, prompting the air to form a top-down air circulation channel inside the protective cover 21. This air circulation not only helps to reduce the temperature of the cutting discs and the stone, but also can promptly discharge the dust and debris generated by the cutting out of the protective cover 21, thereby keeping the working environment clean and reducing equipment wear and safety hazards.

[0070] The four groups of air guide plates 52 are constructed into a structure shaped like a trumpet mouth. When the first cutting disk 22 rotates counterclockwise and the second cutting disk 23 rotates clockwise (also based on the actual rotation direction), when the vortex surges from bottom to top, the special structure of the trumpet mouth can converge and compress the airflow, significantly improving the flow rate of the airflow passing through the ventilation holes 511, and can easily blow away the dust and debris attached to the ventilation holes 511, effectively avoiding the problem of poor ventilation caused by the accumulation of dust and debris, ensuring that the air inside the equipment always maintains a good circulation state, and the threaded holes 53 and bolts 54 allow the top cover 51 to be quickly disassembled, thereby improving the maintainability and use efficiency of the equipment.

[0071] Reference Figure 3 , Fig. 9 and Fig.10 The first cutting disc 22 and the second cutting disc 23 both extend outward from the inside of the protective cover 21 at one end away from the mounting frame 11. The extended end of the first cutting disc 22 is connected to a fine grinding head 26, and the extended end of the second cutting disc 23 is connected to a coarse grinding head 27.

[0072] In use, the multi-axis CNC machining table 1 drives the cutting mechanism 2 to rotate, so that the two cutting discs originally perpendicular to the stone surface become parallel to the stone surface (refer to Fig. 9 ), at this time, the straight line formed by the coarse grinding head 27 and the fine grinding head 26 is parallel to the cutting line, and the cutting line is polished and flattened, thereby scraping off the burrs on the stone.

[0073] At the same time, in the early stage of stone cutting preparation, the outer surface of the stone can also be polished to eliminate protruding parts, enhance the flatness and uniformity of the stone surface, and reduce the stress concentration caused by surface unevenness during the cutting process, thereby effectively preventing the occurrence of edge collapse and improving the quality and yield of stone cutting.

[0074] Finally, it should be pointed out that the methods and devices described in detail above are only embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
