Description

Technical Field

[0001] This utility model belongs to the technical field of stone cutting equipment, specifically relating to an automated and stable single-blade stone cutting device. Background Technology

[0002] Single-blade stone cutting equipment primarily uses a high-speed rotating cutting tool mounted on a spindle to cut stone. A motor drives the spindle to rotate, and the cutting tool contacts the stone surface during rotation. Utilizing the sharp edge of the tool and the cutting force generated by the high-speed rotation, the stone is cut along a predetermined cutting line. The equipment is typically equipped with a feed system to control the movement of the stone or cutting tool during the cutting process, achieving precise cut dimensions and shapes.

[0003] Most existing single-blade stone cutting equipment lacks a blade straightening mechanism. During the cutting process, the blade is prone to deviation due to factors such as uneven stone hardness and changes in cutting resistance. If not corrected in time, the cut stone dimensions will deviate from the design dimensions. Furthermore, blade misalignment will cause the cut surface to become uneven and wavy or bumpy.

[0004] Therefore, an automated and stable single-blade stone cutting device was designed. Utility Model Content

[0008] To solve the above-mentioned technical problems, this utility model provides an automated and stable single-blade stone cutting device, including a support frame, a control cabinet fixedly connected to the top surface of the support frame, a rotating shaft rotatably connected to the bottom surface of the support frame, a blade mounted on one end of the rotating shaft, a cutting table fixedly connected to the side wall of the support frame near the bottom surface, a semi-circular protective cover fixedly connected to the side wall of the support frame, the blade being located inside the semi-circular protective cover, two rangefinders respectively installed on the left and right side walls of the semi-circular protective cover, and a drive assembly installed on the top surface of the support frame;

[0009] The semi-circular protective cover has two top plates symmetrically arranged at the front and back of its inner cavity. Several ball bearings are rotatably connected to the opposite side wall of the top plates. The blade is located between the top plates. Circular plates are fixedly connected to the opposite side walls of the top plates. Two electric push rods are fixedly connected to the left and right side walls of the semi-circular protective cover.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention utilizes a design incorporating a blade, a semi-circular protective cover, a transmission assembly, a top plate, and an electric push rod. The combination of the top plate and the electric push rod allows for real-time monitoring and adjustment of the blade position, ensuring it remains perpendicular or cuts at a preset angle. This improves the straightness and perpendicularity of the cut, resulting in more precise stone dimensions and reducing cutting errors caused by blade misalignment. Applying appropriate pressure through the top plate ensures more even force distribution on the blade during cutting. This prevents excessive localized force from causing accelerated blade wear or chipping, thus extending blade life and reducing tool replacement frequency and costs. Attached Figure Description

[0023] This specific embodiment is an automated and stable single-blade stone cutting device, the structural diagram of which is shown below. Figures 1-4 As shown, the system includes a bracket 1, a control cabinet 2 fixedly connected to the top surface of the bracket 1, a rotating shaft 4 rotatably connected to the bottom surface of the bracket 1, a blade 5 mounted on one end of the rotating shaft 4, a cutting table 9 fixedly connected to the side wall of the bracket 1 near the bottom surface, a semi-circular protective cover 6 fixedly connected to the side wall of the bracket 1, the blade 5 located inside the semi-circular protective cover 6, two rangefinders 14 respectively installed on the left and right side walls of the semi-circular protective cover 6, and a drive assembly installed on the top surface of the bracket 1.

[0024] The rangefinder 14 employs a laser rangefinder, eddy current sensor, or accelerometer, among other sensors. In this design, a laser rangefinder is preferred. It emits a laser beam towards the blade 5 and calculates the distance from the sensor to the blade 5 by measuring the time it takes for the laser to reflect back. When the blade 5 shifts or deforms, the distance between the sensor and the blade 5 changes, thus detecting the change in the blade 5's state. This non-contact measurement method prevents damage to the blade 5; it offers high accuracy, detecting minute distance changes; it provides fast measurement speed, allowing real-time monitoring of the blade 5's state; and it is relatively less affected by environmental factors, adapting to different working environments.

[0025] The semi-circular protective cover 6 has two symmetrically arranged top plates 10 on its front and back. Several ball bearings 11 are rotatably connected to the opposite side wall of the top plate 10. Several grooves 22 are formed on the side wall of the top plate 10, and the ball bearings 11 are tumblingly connected to the grooves 22. The grooves 22 can be used to position the ball bearings 11, so that the ball bearings 11 can rotate at high speed with the blade 5. The blade 5 is located between the top plates 10. Circular plates 13 are fixedly connected to the opposite side wall of the top plates 10. Two electric push rods 12 are fixedly connected to the left and right side walls of the semi-circular protective cover 6, respectively. The output end of the electric push rod 12 is fixedly connected to the circular plate 13. A water outlet assembly is also provided on the side wall of the top plate 10.

[0026] like Figure 2As shown, the drive assembly includes a motor 3 fixedly mounted on the top surface of the bracket 1. Pulleys 7 are fixedly connected to the output shaft of the motor 3 and the end face of the rotating shaft 4, respectively. A belt 8 is connected between the two pulleys 7. The drive assembly is used to drive the blade 5 to rotate, which is a mature existing technology; therefore, it will not be described in detail in this solution.

[0027] like Figure 3 and Figure 4 As shown, the water outlet assembly includes a cavity 17 opened inside the top plate 10. Several water outlet holes 18 communicating with the cavity 17 are opened on the side wall of the top plate 10 near the blade 5. Water inlet holes 16 are opened on the side wall of the circular plate 13. A flexible hose 15 is fixedly connected between the circular plates 13 at the water inlet holes 16. The other end of the flexible hose 15 passes through the semi-circular protective cover 6.

[0028] Specifically, during the cutting process, the friction between the blade 5 and the stone generates a lot of heat. Spraying water can quickly reduce the temperature of the blade 5, prevent it from annealing due to overheating, maintain the hardness and sharpness of the blade 5, and extend its service life. In addition, the stone may develop cracks or discoloration at high temperatures. Spraying water can effectively reduce the surface temperature of the stone, reduce thermal stress, prevent damage to the stone due to overheating, and ensure the quality of the stone.

[0029] like Figure 3 As shown, the other ends of the two hoses 15 on the same side are fixedly connected to the same T-pipe 19, and the other end of the T-pipe 19 is fixedly connected to a connector 20. The T-pipe 19 can be used to divide one stream of fluid into two or more streams, so that the fluid can be distributed into different pipes according to a certain ratio or requirements, so that water can be supplied to the top plates 10 on both sides simultaneously using a single inlet pipe.

[0030] like Figure 3 As shown, a valve 21 is fixedly connected between the tee pipe 19 and the hose 15. By setting the valve 21, the water flow rate can be controlled for cutting different types of stone, meeting different cutting process requirements, and effectively cooling the stone and the blade 5.

[0031] Working principle: During the stone cutting process, the rangefinder 14 can detect the deformation and offset of the blade 5 in real time. When the blade 5 is detected to be offset during rotation, the corresponding electric push rod 12 can be activated. The output end of the electric push rod 12 pushes the top plate 10 to move, so that the balls 11 on both sides of the top plate 10 abut against the blade 5, which is used to correct the blade 5, ensure the stability during the stone cutting process, and avoid the problem of poor cutting accuracy caused by the offset or vibration of the blade 5.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
