Description

Technical Field

[0001] The utility model relates to the technical field of stone processing, in particular to a stone cutting device with a protective structure. Background Art

[0002] At present, stone cutting equipment is widely used in the construction, decoration and other industries. However, traditional stone cutting devices have some shortcomings in the working process, which affects the cutting efficiency and working environment.

[0003] In the existing technology, the stone cutting process often generates a large amount of dust and high temperature. These dusts not only pollute the environment, but also threaten the health of operators. High temperature accelerates the wear of cutting blades and shortens the service life of equipment. At the same time, the vibration and noise generated during the cutting process also affect the working environment and cutting accuracy.

[0004] Chinese invention patent CN117621268B discloses an ultra-fine wire single-station stone cutting machine, which uses diamond wire for cutting. A ball screw and a column are installed on the fixed frame, and the cutting frame is connected to the movable end of the ball screw. A protective frame and rollers are installed in the movable frame. The winding structure is connected by diamond wire to achieve stone cutting. This design reduces the generation of dust during the cutting process by using diamond wire, ensures the safety of workers, and can quickly cut the stone into multiple stone slabs. However, the device has the following shortcomings: the device does not provide an effective solution to the vibration and noise during the cutting process, which affects the cutting accuracy and working environment.

[0005] Chinese invention patent CN113787629B discloses an environmentally friendly cutting method for a beaded wire saw. The device includes a water storage tank, a column and a sealing box. A flushing device is provided to flush the contact area between the beaded wire saw blade and the stone to achieve the effect of cooling and reducing dust. The design reduces the cutting temperature and dust through the flushing device, which plays a positive role in environmental protection. It can also achieve two cutting methods: horizontal cutting and vertical cutting. However, it still has the following limitations: the replacement of the beaded wire saw blade still requires manual operation, which is time-consuming and labor-intensive, affecting work efficiency. No effective mitigation measures are proposed for the vibration and noise during the cutting process, which may affect the cutting quality and operating comfort. Utility Model Content

[0046] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0047] It is to be noted that the directions of "left", "right", "up", "down", "front", "back", "inside" and "outside" in the following schemes are all relative directions and are not listed here one by one.

[0048] Example 1

[0049] like Figures 1 to 12 As shown, this embodiment provides a stone cutting device with a protective structure, including a rotating shaft 1, a saw blade body 2 is sleeved on the outer end of the rotating shaft 1, and a plurality of cutting blades 3 are fixedly connected to the outer end of the saw blade body 2.

[0050] The cutting blade 3 is provided with a plurality of cooling holes 4 along its radial direction, and the saw blade body 2 is provided with cooling holes 5 and through holes 6 connected to the cooling holes 4, forming a cooling water flow channel for internal cooling of the cutting blade 3 and reducing the cutting temperature.

[0051] The saw blade body 2 is provided with a shock-absorbing groove 7 and a chip discharge groove 8. The shock-absorbing groove 7 is used to reduce vibration and noise generated during the cutting process, and the chip discharge groove 8 is used to discharge stone chips generated by cutting to prevent stone chips from accumulating and affecting the cutting effect.

[0052] A water tank 14 is provided on the lower side of the saw blade body 2. The water tank 14 is filled with water, and the water submerges the top of the stone to be cut. The water tank 14 is used to cool the cutting blade 3 and reduce dust generated during the cutting process.

[0053] Adjustment component one and adjustment component two are fixedly connected to bracket three 17. Adjustment component one and adjustment component two are symmetrically arranged about the plane passing through the axis of rotation shaft one 1 and rotation shaft two 10. Adjustment component one and adjustment component two both include symmetrically arranged branch pipes 18. Multiple spray and suction holes 19 are provided at one end of the branch pipe 18 close to the saw blade body 2, and the main pipe 20 is fixedly connected to the other end of the branch pipe 18 away from the saw blade body 2.

[0054] The main pipe 20 and the branch pipe 18 are both hollow structures, and the hollow parts of the main pipe 20 and the branch pipe 18 are connected, and the spray and suction holes 19 are connected to the hollow parts of the branch pipe 18. The adjustment components 1 and 2 cool the saw blade body 2 and the cutting blade 3 and clean the stone chips by adjusting the high-pressure water flow and negative pressure suction, thereby reducing vibration and noise.

[0055] Working process:

[0056] Fix the stone to be cut on the mobile platform in the water tank 14 to ensure that the stone is stable, and inject clean water into the water tank 14 until the water level reaches the height of submerging the top of the stone to ensure that the cutting area is covered by water.

[0057] The motor 13 is started, and the power shaft of the motor 13 is fixedly connected to the second rotating shaft 10 through a coupling, driving the second rotating shaft 10 to rotate.

[0058] The outer end of the rotating shaft 10 is threadedly connected to the pulley 11, and the pulley 11 is connected to the pulley 9 on the rotating shaft 1 through the belt 12. The rotation of the belt 12 drives the pulley 9 to rotate, thereby driving the rotating shaft 1, the saw blade body 2 and the cutting disc 3 to rotate at high speed.

[0059] The rotating cutting blade 3 contacts the stone and starts to cut the stone. The cooling hole 1 4 on the cutting blade 3, the cooling hole 2 5 on the saw blade body 2 and the through hole 6 form a cooling water flow channel, which allows water to flow into the cutting blade 3 for internal cooling.

[0060] During the cutting process, the branch pipes 18 of the regulating assembly 1 and the regulating assembly 2 are connected to the high-pressure water source or the negative pressure system through the main pipe 20.

[0061] When connected to a high-pressure water source, high-pressure water flows through the spray and suction holes 19 onto the saw blade body 2 and the cutting blade 3, thereby enhancing the cooling effect and flushing stone chips away from the cutting area.

[0062] When connected to the negative pressure system, the spray-suction holes 19 generate negative pressure suction to suck away stone chips and water in the cutting area, keeping the cutting area clean.

[0063] The shock-absorbing groove 7 on the saw blade body 2 effectively reduces vibration and noise during the cutting process, thereby improving the stability and accuracy of cutting.

[0064] The chip removal groove 8 quickly discharges the stone chips generated by cutting to prevent the accumulation of stone chips that affects the cutting efficiency.

[0065] Through the cooling water flow channel formed by cooling hole 1 4, cooling hole 2 5 and through hole 6, water can directly enter the interior of the cutting blade 3, perform efficient internal cooling, significantly reduce the cutting temperature, prevent the cutting blade 3 from being worn or damaged due to overheating, and extend its service life.

[0066] The shock-absorbing groove 7 on the saw blade body 2 effectively reduces vibration and noise during the cutting process, improves the operating stability of the equipment, improves the operating environment, and improves work efficiency.

[0067] The chip discharge groove 8 is provided to discharge the stone chips generated by cutting quickly, thereby preventing the stone chips from accumulating and causing jamming or uneven cutting surface, thereby improving the cutting quality.

[0068] Adjustment component 1 and adjustment component 2 realize external cooling and stone chip cleaning of saw blade body 2 and cutting disc 3 through high-pressure water flow and negative pressure suction, further reducing cutting temperature and keeping cutting area clean.

[0069] By adjusting the high-pressure water flow and negative pressure suction modes, it can be flexibly adjusted according to actual cutting needs to meet the requirements of different stones and cutting conditions, thereby improving the applicability and flexibility of the equipment.

[0070] The design of the water tank 14 allows the cutting area to be covered with water, effectively reducing the dust generated during the cutting process, protecting the health of the operator, and complying with environmental protection requirements.

[0071] The overall structure is reasonably designed, and key components such as the rotating shaft 1, saw blade body 2, cutting disc 3, etc. are made of high-strength materials to ensure that the equipment still has good performance under long-term and high-load working conditions.

[0072] Since the stone chips are cleaned in time, impurities are not easily accumulated inside the equipment, which reduces the difficulty of maintenance and extends the service life of the equipment.

[0073] The stone cutting device of this embodiment achieves efficient cooling of the cutting blade 3 and rapid cleaning of stone chips, reduces vibration and noise, improves cutting quality and equipment stability, and at the same time, is easy to operate and has a wide range of applications, and has significant practical value and promotion prospects.

[0074] Example 2

[0075] like Figures 1 to 12 As shown, based on Example 1, the structure and function of the stone cutting device are further optimized, support and adjustment mechanisms are added, and the stability, adjustability and safety of the equipment are improved.

[0076] The end of bracket 15 away from rotating shaft 2 10 is fixedly connected to the shell part of motor 13, which enhances the fixation of motor 13 and reduces vibration during operation. The end of bracket 2 16 away from saw blade body 2 is fixedly connected to bracket 3 17, which provides additional support for the entire device and improves the stability of the equipment.

[0077] The top of the main pipe 20 is fixedly connected to a rack, the top of the rack is meshed with a gear, and the position corresponding to the gear on the bracket three 17 is fixedly connected to an adjusting motor, and the power shaft of the adjusting motor passes through the bracket three 17 and is fixedly connected to the gear.

[0078] Between bracket 1 15 and bracket 2 16, a splash shield is fixedly connected to the upper side of the saw blade body 2. The splash shield covers the top of the saw blade body 2 and the cutting disc 3 to prevent water and stone chips from splashing during the cutting process and protect the safety of the operator.

[0079] The end of the main pipe 20 away from the branch pipe 18 is connected to the external hydraulic system, which can provide high-pressure water flow or negative pressure suction as needed. The outer end of the main pipe 20 is slidably connected to the bracket 3 17, so that the main pipe 20 and the branch pipe 18 can move up and down to adjust the position of the spray and suction holes 19.

[0080] The top of the water tank 14 is 20 to 30 cm higher than the top of the branch pipe 18, ensuring that the lowest liquid level in the water tank 14 is higher than the top of the branch pipe 18. This design ensures that the spray and suction holes 19 of the branch pipe 18 are always immersed in water, preventing air from entering the hydraulic system and affecting the effects of high-pressure water flow and negative pressure suction.

[0081] Working process:

[0082] The stone to be cut is fixed on a movable platform in the water tank 14 to ensure that the stone is stable and in the correct position.

[0083] Pour clean water into the water tank 14 until the water level reaches a position 20 to 30 cm above the top of the branch pipe 18, ensuring that the spray and suction holes 19 of the branch pipe 18 are completely immersed in water.

[0084] The motor 13 is started, and the power shaft of the motor 13 drives the second rotating shaft 10 to rotate through the coupling.

[0085] The pulley 2 11 at the outer end of the rotating shaft 2 10 drives the pulley 1 9 on the rotating shaft 1 1 to rotate through the belt 12, thereby driving the rotating shaft 1 1, the saw blade body 2 and the cutting disc 3 to rotate at high speed.

[0086] The rotating cutting blade 3 comes into contact with the stone and starts cutting the stone.

[0087] During the cutting process, the shock-absorbing groove 7 on the saw blade body 2 and the bracket structure work together to reduce vibration and noise and improve cutting stability.

[0088] According to the cutting requirements, the adjusting motor is started, and the power shaft of the adjusting motor drives the main pipe 20 to move up and down through the gear and rack, driving the branch pipe 18 to adjust the height.

[0089] By adjusting the position of the branch pipe 18, the spraying and suction holes 19 are precisely aligned with specific positions of the saw blade body 2 and the cutting disc 3, thereby enhancing the cooling and cleaning effects.

[0090] The external hydraulic system provides high-pressure water flow or negative pressure suction force to the main pipe 20 .

[0091] High-pressure water flow mode: High-pressure water flow is sprayed onto the saw blade body 2 and the cutting disc 3 through the main pipe 20, the branch pipe 18 and the spray and suction holes 19 for external cooling and flushing of stone chips.

[0092] Negative pressure suction mode: Negative pressure suction sucks away water and stone chips near the saw blade body 2 and cutting disc 3 through the spray suction hole 19 to keep the cutting area clean.

[0093] The sliding connection between the main pipe 20 and the bracket 3 17 ensures smooth and unobstructed movement during the adjustment process.

[0094] The anti-splash cover prevents high-pressure water and stone chips from splashing outward, ensuring the safety of operators.

[0095] The liquid level design of the water tank 14 prevents air from entering the hydraulic system, ensuring stable effects of high-pressure water flow and negative pressure suction.

[0096] Bracket 1 15 is fixedly connected to the housing of the motor 13, and bracket 2 16 is fixedly connected to bracket 3 17, forming a stable support structure, reducing vibration during operation of the equipment and improving cutting accuracy.

[0097] The regulating motor drives the main pipe 20 up and down through the gear and rack, thereby achieving precise adjustment of the position of the branch pipe 18. The position of the spray and suction holes 19 can be flexibly adjusted according to different cutting requirements to optimize the cooling and cleaning effects.

[0098] The anti-splash cover effectively prevents the splash of water and stone chips during cutting, protecting the operator from injury.

[0099] The design of the liquid level of the water tank 14 ensures the stable operation of the hydraulic system and prevents unstable pressure or insufficient suction caused by air entering.

[0100] The connection between the main pipe 20 and the external hydraulic system makes the provision of high-pressure water flow and negative pressure suction more stable and controllable.

[0101] The position of the branch pipe 18 is adjustable, and the spray and suction holes 19 can accurately act on the parts that need cooling and cleaning, thereby improving the efficiency of cooling and stone chip cleaning.

[0102] The design of the bracket three 17 enables the main pipe 20 to be slidably connected to the bracket three 17, making it more convenient to adjust and maintain the main pipe 20 and the branch pipe 18.

[0103] The stability of the bracket structure reduces the wear of various parts of the equipment and extends the service life of the equipment.

[0104] Through precise cooling and stone chip cleaning, the cutting disc 3 is always kept in the best working condition, the cutting surface is flat and smooth, and the cutting quality is significantly improved.

[0105] The shock-absorbing groove 7 and the support structure together reduce vibration and noise, making the cutting process more stable and more precise.

[0106] The efficient cooling and cleaning system reduces water waste, and the water in the water tank 14 can be recycled, meeting environmental protection requirements.

[0107] It prevents the spillage of dust and stone chips, improves the working environment and protects the health of operators.

[0108] This embodiment improves the overall stability of the equipment by adding a stable connection between bracket 1 15, bracket 2 16 and bracket 3 17, and adjusts the combination of the motor, gear and rack to achieve precise adjustment of the main pipe 20 and the branch pipe 18, making cooling and cleaning more efficient. The provision of the splash guard and the design of the liquid level of the water tank 14 enhance the safety and reliability of the equipment. The optimization of the overall structure has comprehensively improved the performance of the stone cutting device, which has higher practical value and market competitiveness.
