Detailed Implementation

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0020] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0021] This utility model embodiment provides an automatic edge trimming machine, such as Figure 1-4 As shown, the automatic edge-cutting machine includes: a frame 1, on which a housing 2 is fixedly installed to shield against flying debris; an electric hydraulic rod 4 disposed within the housing 2, the output rod of which is fixedly mounted with a power head 6 via a connecting frame 5 for controlling the lifting and lowering of the power head 6, and a cutting disc 7 mounted on the output shaft of the power head 6 for edge-cutting of the stone slab 20; an electric guide rail 3 fixedly installed within the housing 2, the output block of which is fixedly connected to the electric hydraulic rod 4 for controlling the movement of the electric hydraulic rod 4, the power head 6, and the cutting disc 7 to cut the stone slab 20; a placement plate 17 fixedly installed on the frame 1 for placing the stone slab 20 to be edge-cut; and a cooling mechanism disposed on the housing 2 for spraying water to cool the cutting disc 7.

[0022] In this embodiment, the frame 1 serves as the basic support structure of the entire automatic edge-cutting machine, providing a stable mounting platform for all components and ensuring the stability of the equipment during operation. The housing 2 effectively shields against flying debris, limiting the range of debris ejection from the source and greatly reducing the possibility of debris scattering throughout the workshop, effectively protecting the personal safety of workshop workers and reducing the risk of stone chips flying into workers' eyes and injuring their skin. It also prevents debris from accumulating around the equipment, maintaining workshop cleanliness and preventing equipment malfunctions due to debris buildup. The output rod of the electro-hydraulic rod 4 is securely connected to the power head 6 via the connecting frame 5. During operation, the electro-hydraulic rod 4 precisely extends and retracts according to processing requirements, driving the connecting frame 5 and the power head 6 fixed thereon to perform lifting and lowering movements. The output shaft of the power head 6 is equipped with a cutting disc 7, providing stable and controllable power to drive the cutting disc 7 to rotate at high speed and perform stone edge-cutting operations. The electro-hydraulic rod 4 can flexibly and precisely adjust the height of the cutting disc 7 to adapt to the edge-cutting requirements of stone slabs 20 of different thicknesses. Compared to traditional manual hand-held cutting tools, which struggle to precisely control cutting depth and position, this automated lifting and control system significantly improves cutting accuracy and ensures the quality of stone processing. Furthermore, workers no longer need to manually operate the cutting tools at close range, further reducing the risk of debris splashing and enhancing operational safety. The electric guide rail 3 is securely installed inside the machine housing 2, with its output block fixedly connected to the electric hydraulic rod 4. During operation, the electric guide rail 3 smoothly drives the output block according to a pre-set program, thereby causing the electric hydraulic rod 4, power head 6, and cutting disc 7 to move horizontally along the guide rail. The electric guide rail 3 allows the cutting disc 7 to move freely and precisely to different positions on the stone slab 20, achieving automated slab cutting. On the one hand, it improves processing efficiency and quickly completes complex edge cutting patterns; on the other hand, compared with manual handling of stone and adjustment of cutting position, the frequency of contact between workers and high-speed rotating cutting disc and flying debris is greatly reduced, ensuring worker safety in all aspects and reducing stone loss caused by human operation errors; the placement plate 17 is firmly fixed on the frame 1 and is specially used to place the stone slab 20 to be cut. Workers only need to place the stone slab on the placement plate 17 according to the specifications, and the equipment will automatically carry out the subsequent edge cutting process; it provides a stable placement platform for the stone, avoiding the stone from shaking or shifting during the edge cutting process and ensuring edge cutting accuracy; after placing the stone, workers can quickly retreat to a safe area without having to hold the stone with their hands throughout the process, staying away from the range of flying debris and reducing the risk of injury; the cooling mechanism is installed on the machine box 2, and during the operation of the cutting disc 7, it sprays water to make the fine water flow evenly sprinkle on the surface of the cutting disc 7; the high-speed rotation of the cutting disc 7 and the intense friction with the stone will generate a lot of heat. If the heat accumulates too much, it will easily cause the cutting disc to deform, wear more, and shorten its service life. The cooling mechanism sprays water in a timely manner to cool down the cutting disc 7, maintain its normal operating temperature, and extend its durability. At the same time, the water flow can also carry away some debris and dust, causing them to settle and further reducing the amount of flying debris, which is beneficial to the cleanliness of the workshop environment.

[0023] In a further preferred embodiment of this utility model, the cooling mechanism includes: a mounting shell 8 disposed inside the chassis 2, the mounting shell 8 being fixedly connected to the power head 6 via a bracket; a telescopic pipe 9 fixedly mounted on the mounting shell 8, the water outlet end of the telescopic pipe 9 extending out of the mounting shell 8; a nozzle 10 fixedly mounted on the water outlet end of the telescopic pipe 9 for spraying water onto the cutting disc 7; and a water tank 11 fixedly mounted on the chassis 2 for holding cooling water, a water pump 12 for pumping water being fixedly mounted on the top of the water tank 11, the water outlet end of the water pump 12 being fixedly connected to the water inlet end of the telescopic pipe 9 and a water suction pipe 13 fixedly connected to the water inlet end of the water pump 12, the water inlet end of the water suction pipe 13 extending into the water tank 11.

[0024] In this embodiment, the mounting shell 8 is placed inside the housing 2 and is fixedly connected to the power head 6 by means of a bracket. This stable connection allows the mounting shell 8 to move synchronously with the power head 6, always maintaining its relative position to the cutting disc 7. Since the cutting disc 7 continuously adjusts its position under the coordinated action of the electric guide rail 3 and the electric hydraulic rod 4 to perform edge cutting work on different parts of the stone, the following characteristic of the mounting shell 8 ensures that the subsequent cooling components can accurately position the cutting disc 7. No matter how the cutting disc 7 moves, the cooling mechanism can still function. When the cutting disc 7 rises, falls, or moves horizontally with the power head 6, the telescopic tube 9 adjusts its length in a timely manner according to the actual distance changes. The nozzle 10 is firmly installed at the water outlet end of the telescopic tube 9 and is precisely aligned with the cutting disc 7. After the water pump 12 starts pumping water, the water flows quickly through the telescopic pipe 9 to the nozzle 10. The nozzle 10 evenly disperses and atomizes the water, spraying it finely onto the cutting disc 7. The water flow can cover a large area of ​​the cutting disc 7, improving heat dissipation efficiency and quickly removing the heat generated by the high-speed rotation and friction of the cutting disc 7. Moreover, compared with direct water flow impact, the fine water mist is less likely to interfere with the rotational balance of the cutting disc 7, ensuring cutting accuracy. It can also maximize the encapsulation and settling of cutting debris, reducing debris flying. The water tank 11 is firmly fixed on the machine casing 2 and serves as a storage container for cooling water. Its volume is reasonably designed to meet the continuous water demand during the stone cutting process. Workers only need to check the water level periodically and replenish the water as needed. The water pump 12 is fixedly installed on the top of the water tank 11. When working, it is connected to the power supply and starts according to the set program, generating strong suction and pressure to draw water from the water tank 11, pressurize the water, and deliver it to the telescopic pipe 9.

[0025] In a further preferred embodiment of the present invention, a placement plate 17 is fixedly installed on the frame 1 for placing the stone slab 20 to be cut, and a cylinder 18 is fixedly installed inside the machine housing 2. A pressure plate 19 is fixedly installed on the output rod of the cylinder 18 for pressing and securing the stone slab 20 placed on the placement plate 17 during the cutting process.

[0026] In this embodiment, the placement plate 17 is securely fixed on the frame 1. During operation, the worker only needs to place the stone slab 20 to be cut horizontally on the surface of the placement plate 17. The material of the placement plate 17 has a certain strength and wear resistance, which can bear the weight of the stone slab 20. At the same time, its surface has high flatness, which meets the placement requirements of the stone slab 20. It provides a stable and regular placement platform for the stone slab 20, effectively preventing the stone from shaking or tilting due to uneven placement surface. A stable placement is fundamental to ensuring the accuracy of subsequent cutting, reducing cutting errors caused by stone displacement, and ensuring that the cut edges are straight and dimensionally accurate, meeting the process standards for stone processing. It also allows workers to quickly and accurately place the stone, improving work efficiency. The cylinder 18 is firmly installed inside the machine housing 2. When the stone slab 20 is properly placed, the cylinder 18 starts according to the control system command or preset program, and its output rod extends outward, driving the pressure plate 19 fixed on the output rod to move down synchronously. After cutting is completed, the cylinder 18 drives the pressure plate 19 to rise and reset.

[0027] In a further preferred embodiment of the present invention, a collection tank 14 is fixedly installed on the frame 1 for collecting debris and wastewater. A drain pipe 15 is fixedly connected to the bottom of the collection tank 14. A collection box 16 is provided on the frame 1 for collecting wastewater and impurities.

[0028] In this embodiment, the collection trough 14 is securely mounted on the frame 1, and its position is carefully considered, located below the cutting disc 7 and around the stone slab 20. During the stone cutting operation, the cutting debris, along with the water sprayed by the cooling mechanism, falls to the ground under gravity. At this time, the collection trough 14 plays a crucial role, intercepting and collecting as much of the falling debris and wastewater as possible with its wide, open design. In traditional stone cutting, debris and wastewater scatter indiscriminately, soiling the workshop floor, increasing cleaning difficulty, consuming a lot of manpower and time, and potentially causing the floor to become slippery, creating a safety hazard of workers slipping and getting injured. The collection tank 14 effectively solves this problem by collecting debris and wastewater, keeping the workshop floor clean and reducing cleaning frequency. It also prevents wastewater from flowing to critical equipment parts, preventing short circuits, rust, and damage caused by water accumulation and impurities, thus extending equipment lifespan. The drain pipe 15 is fixedly connected to the bottom of the collection tank 14. Its diameter is rationally designed based on wastewater flow and debris size, and its smooth inner wall reduces water flow resistance and debris accumulation. When the debris and wastewater in the collection tank 14 accumulate to a certain level, the wastewater automatically flows downwards along the drain pipe 15 due to gravity and the liquid level difference. The smooth drain pipe ensures that the collection tank 14 will not overflow, maintaining stable operation of the collection system. The smooth inner wall reduces the probability of debris adhering to the wall and clogging the pipe, ensuring the continuity and stability of wastewater discharge, reducing equipment maintenance costs, and improving overall wastewater discharge efficiency. The collection box 16 is placed on the frame 1, precisely aligned with the end of the drain pipe 15, facilitating the receipt of debris and wastewater discharged from the drain pipe 15. Collection box 16 can store sewage impurities in a large capacity, reducing the frequency of cleaning.

[0029] In a further preferred embodiment of this utility model, the chassis 2 is provided with a placement opening, the chassis 2 is provided with a detachable maintenance plate, and the maintenance plate is provided with a visual observation window.

[0030] In this embodiment, a precise placement opening is provided on the chassis 2, its size adapted to the operational needs of daily equipment maintenance and component replacement. When the equipment malfunctions, or when critical internal components such as the electro-hydraulic rod 4, electric guide rail 3, and power head 6 need to be periodically inspected and adjusted, the operator first removes the detachable inspection plate from the chassis 2, allowing direct access to the internal structure of the chassis through the placement opening; after maintenance, the inspection plate is then securely reinstalled in its original position; the visual observation window is cleverly placed on the inspection plate, mostly made of transparent, high-strength acrylic or tempered glass, which can withstand a certain degree of impact and high temperature inside the chassis while also having good light transmission. During equipment operation, the operator can monitor the working status of the cutting disc 7, check the movement trajectory of the electric guide rail 3, and observe for any debris accumulation or abnormal component vibration through the observation window; before the equipment is shut down for maintenance, the operator can also use the observation window to make a preliminary judgment on the general internal condition.

[0031] In a further preferred embodiment of the present invention, a water replenishment hopper is provided on the top of the water tank 11, and an openable and closable cover plate is hinged to the top of the water replenishment hopper.

[0032] In this embodiment, the water replenishment bucket is stably positioned on top of the water tank 11. Its shape is generally that of a funnel, wider at the top and narrower at the bottom, with a large opening that connects to the outside, facilitating the operator's replenishment of water into the tank 11. During the stone cutting process, as the cooling mechanism continues to operate, the water in the tank 11 will gradually be consumed. When the water level drops to a certain level, potentially affecting the cooling effect, the operator simply needs to hold a container and slowly pour water into the tank 11 through the water replenishment bucket.

[0033] In a further preferred embodiment of this utility model, a rubber pad is fixedly installed at the bottom of the pressure plate 19 for anti-slip purposes, and anti-slip foot pads are symmetrically fixedly installed on the frame 1.

[0034] In this embodiment, the rubber pad is firmly fixed to the bottom of the pressure plate 19. When the cylinder 18 drives the pressure plate 19 to press down and make it contact the stone slab 20 placed on the placement plate 17, the rubber pad directly adheres to the stone surface. The rubber pad is soft and elastic and has a certain coefficient of friction.

[0035] In summary, the machine housing 2 provides all-around protection against flying debris, limiting the range of debris ejection and reducing the risk of stone chips causing injury to workers' eyes and skin, keeping workers away from the debris-splashing area; the electric guide rail 3 and electric hydraulic rod 4 enable automated edge cutting, reducing the frequency of worker contact with the high-speed rotating cutting disc and flying debris; the placement plate 17 allows workers to quickly place the stone and then retreat to a safe area; the pressure plate 19, driven by the cylinder 18, presses the stone firmly, preventing the stone from jumping, shifting, and colliding with the cutting disc, ensuring the safety of operators in all aspects; the electric hydraulic rod 4 precisely controls the height of the cutting disc 7, adapting to stone slabs 20 of different thicknesses, overcoming the drawbacks of traditional manual methods that struggle to accurately control the cutting depth and position, and significantly improving cutting accuracy; the electric guide rail 3 drives the cutting disc 7 to move precisely, achieving complex cutting patterns and completing automated slab cutting; the placement plate 17 provides a stable and flat placement platform for the stone, preventing the stone from shaking or tilting, reducing cutting errors, ensuring accurate cutting dimensions and straight edges, and conforming to processing standards.
