Description

Technical Field

[0001] The invention relates to the field of stone processing, in particular to a granite cutting device. Background Art

[0002] Granite is hard, acid- and alkali-resistant, and weather-resistant. It also has good decorative properties, bright colors, and is solemn and elegant. It is suitable for public places and outdoor decoration. It is widely used in the construction field, such as the production of floors, walls, columns, and other components. At the same time, granite is also one of the preferred materials for sculpture art, and is often used to make statues, monuments, and other artworks.

[0003] Granite is usually pre-processed into slabs or blocks. These stones are heavy and inconvenient to move. Cutting is mainly done by manual cutting machines. The inconvenience of manual operation is mainly reflected in the following points:

[0004] First, there are certain differences in the thickness and width of stones of different specifications, and manual operation requires adjusting the clamps, which is troublesome;

[0005] Second, continuous cutting cannot be achieved, and the machine needs to be stopped to retrieve materials;

[0006] Third, it is troublesome to change the cross-cutting and bevel-cutting, and the angle of the cutting device needs to be adjusted manually;

[0007] The purpose of the present invention is to provide a new stone processing equipment to solve the above technical problems. Summary of the invention

[0008] The object of the present invention is to provide a granite cutting device to solve the problems mentioned in the background technology.

[0009] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: including a stone bearing device, a stone conveying device, a longitudinal linear motor, a circular ring, a direction-changing servo motor, a bearing plate and a transverse linear motor, wherein the stone bearing device is used to bear stones, the stone conveying device is used to convey stones, the longitudinal linear motor is adjacent to the stone bearing device, the moving direction of the longitudinal linear motor mover is parallel to the stone conveying direction, the circular ring is located above the longitudinal linear motor mover, the front and rear ends of the bottom of the circular ring are formed with connecting arms to connect the circular ring with the mover of the longitudinal linear motor, a support block is arranged in the middle of the circular ring, and the side of the support block The changing direction servo motor is connected to the circular ring through the first support bar, and the changing direction servo motor is located above the support block. The bottom end of the rotating shaft of the changing direction servo motor passes through the support block and forms a rotating pair with the support block. The changing direction servo motor is fixed to the first support bar through the second support bar. A sliding sleeve is arranged on the bearing plate, and the sliding sleeve is arranged on the circular ring and can move along the circular ring. One end of the bearing plate is fixedly connected to the changing direction servo motor, and the other end of the bearing plate is located above the stone bearing device. The transverse linear motor is installed on the bearing plate, and the moving direction of the transverse linear motor mover is parallel to the length direction of the bearing plate.

The baffle is arranged in the chip groove and can move up and down along the chip groove to form a moving pair in the vertical direction with the chip groove. The baffle is located in the front side of the chip groove and the bottom end of the baffle is connected to the elastic rubber strip.

[0011] As a further improvement of the above technical solution: the stone bearing device also includes rollers, which are rotatably arranged on the top of the baffle and the rear side of the bearing platform, and the rollers are arranged along the stone conveying direction. The purpose of setting the rollers is to improve the lubricity of the stone when it contacts the baffle and the receiving platform, and to convert the sliding friction into rolling friction to avoid wear on the stone surface.

[0033] The stone carrying device 1 is used to carry stones. The stone carrying device 1 includes a carrying platform 101, an elastic rubber strip 102, a baffle 103 and a roller 105. The carrying platform 101 is formed with chip grooves 104 arranged in parallel with equal intervals along the stone conveying direction. The elastic rubber strip 102 is filled in the chip groove 104 and is located in the front side of the chip groove 104. The baffle 103 is arranged in the chip groove 104 and can move up and down along the chip groove 104 to form a moving pair in the vertical direction with the chip groove 104. The baffle 103 is located in the front side of the chip groove 104 and the bottom end of the baffle 103 is connected to the elastic rubber strip 102. The roller 105 is arranged on the top of the baffle 103 and the rear side of the carrying platform 101 and can rotate. The roller 105 is arranged along the stone conveying direction.

[0034] The stone conveying device 2 is used to convey stones. The stone conveying device 2 includes a plurality of conveying motors 201 and rollers 202. The conveying motors 201 are connected to the stone carrying device 1. The conveying motors 201 are distributed along the stone conveying direction and the rollers 202 are connected to the rotating shafts of the conveying motors 201. The rollers 202 are used to support the stones. The cross-sectional area of ​​the rollers 202 gradually increases along the stone conveying direction and the surfaces of the rollers 202 are covered with rubber.

[0035] The longitudinal linear motor 3 is adjacent to the stone carrying device 1, and the moving direction of the rotor of the longitudinal linear motor 3 is parallel to the stone conveying direction.

[0036] The circular ring 4 is located above the rotor of the longitudinal linear motor 3, and connecting arms 401 are formed at the front and rear ends of the bottom of the circular ring 4 to connect the circular ring 4 with the rotor of the longitudinal linear motor 3. A support block 402 is arranged in the middle of the circular ring 4, and the side of the support block 402 is connected to the circular ring 4 through a first support bar 403.

[0037] The direction-changing servo motor 5 is located above the support block 402 , and the bottom end of the rotating shaft of the direction-changing servo motor 5 passes through the support block 402 and forms a rotating pair with the support block 402 . The direction-changing servo motor 5 is fixed to the first support bar 403 via the second support bar 501 .

[0038] The bearing plate 6 is provided with a sleeve 601 , which is sleeved on the ring 4 and can move along the ring 4 . One end of the bearing plate 6 is fixedly connected to the direction-changing servo motor 5 , and the other end of the bearing plate 6 is located above the stone bearing device 1 .

[0039] The transverse linear motor 7 is installed on the supporting plate 6, and the moving direction of the rotor of the transverse linear motor 7 is parallel to the length direction of the supporting plate 6. A cutting device 701 for cutting stone is installed on the rotor of the transverse linear motor 7. The cutting device 701 refers to a device for cutting stone in the prior art. It belongs to the prior art content and is known to technical personnel in this field. Therefore, the specific structure and working principle of the cutting device 701 will not be further described in a timely manner.

[0040] The fan 8 is tilted and arranged above the stone carrying device 1, and the air outlet of the fan 8 points to the chip groove 104. The depth of the rear side of the chip groove 104 gradually increases in a tilted shape along the stone conveying direction.

[0041] Working principle: The stone is placed on the supporting platform 101. Since the contact area between stones of different widths and the supporting platform 101 is different, the number of baffles 103 squeezed by the bottom surface of the stone is also different. After being squeezed by the stone, the baffle 103 will move down along the chip groove 104 to squeeze the elastic rubber strip 102, while the baffles 103 on the left and right sides of the stone that are not squeezed will play a blocking role to prevent the stone from falling from the stone supporting device 1 when being transported on the stone conveying device 2.

[0042] The operator places the stone on the supporting platform 101 and pushes it toward the front of the supporting platform 101. The rollers 202 with different cross-sectional areas on the stone conveying device 2 can be suitable for stones of different thicknesses. At the same time, the elastic rubber strip 102 can shrink so that the baffle 103 squeezed by the bottom surface of the stone and the roller 202 can clamp the stone together. The rotating roller 202 cooperates with the roller 105 on the baffle 103 to convey the stone to the front of the supporting platform 101. Then the horizontal linear motor 7 drives the cutting device 701 to move to cut the stone. The cut stone can be pushed by the stone conveyed by the stone conveying device 2 and fall from the supporting platform 101.

[0043] The cutting device 701 is arranged on the mover of the transverse linear motor 7, and the transverse linear motor 7 is installed on the rotatable connecting arm 401. The incision angle of the cutting device 701 on the stone can be adjusted by driving the connecting arm 401 to rotate through the reversing servo motor 5, and different cutting requirements of the stone (such as cross cutting and oblique cutting) can be met. During the process of cutting the stone by the cutting device 701, the moving speed of the mover of the longitudinal linear motor 3 is consistent with the conveying speed of the stone, so that the cutting device 701 and the stone are in a relatively static state, and the cutting of the stone can be completed without pausing while maintaining the state of stone conveying.

[0044] The debris generated during the stone cutting process can fall into the chip groove 104, which can prevent the debris from accumulating at the bottom of the stone, causing the stone to be partially supported and affecting the stability of the stone during cutting. When the debris needs to be cleaned, the fan 8 is started, and the fan 8 forms an airflow to blow the debris off along the inclined chip groove 104.

[0045] The control method of the present invention is to realize automatic control of various electrical components through an external controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.
