Description

Technical Field

[0001] The present invention relates to the technical field of equipment for processing stone slabs, and more specifically, to a stone cutting device with an anti-collapse mechanism for processing stone slabs. Background Art

[0002] Slate refers to a building material that is chiseled or artificially formed and solidified from dense rock. In order to make the slate more in line with the actual needs of users, relevant staff often use stone cutting devices to cut the slate. The patent document with the prior art publication number CN213919036U provides a cutting device for processing microcrystalline slates. The device uses a lifting cylinder in conjunction with a support plate and a cutting wheel to lift and cut the microcrystalline slate and can clamp and fix microcrystalline slates of different sizes. Although the device has many beneficial effects, the following problems still exist: the device only uses a clamping plate to fix the edge of the slate. When the user uses the device to cut the slate, the position where the slate contacts the cutting wheel will produce obvious vibrations, and the cut slate is prone to edge collapse defects, which will seriously reduce the quality of the slate and affect the normal use of the slate.

[0003] The anti-collapse mechanism in the prior art CN216914418U is arranged on both sides of the cutting mechanism to provide a guide for the overall transverse cutting drive to avoid the cutting mechanism from moving slightly forward and backward during transverse cutting of the stone slab and causing edge collapse. In the actual working process, the fixation of the stone slab and the stability of the stone slab near the cutting position have a greater impact on the edge collapse of the stone slab. In view of this, we propose a stone cutting device with an anti-collapse mechanism for stone slab processing. Summary of the invention

[0017] 3. Beneficial effects

[0018] Compared with the prior art, the advantages of the present invention are:

[0034] A stone cutting device with an anti-collapse mechanism for stone slab processing comprises a mounting base 1, a movable frame 3 is provided on the right side of the mounting base 1, which is limited by the mounting base 1 and slidably connected to the mounting base 1, a placement plate 2 is provided on the upper side of the mounting base 1, a cutting groove 202 is provided on the side of the placement plate 2 close to the movable frame 3, and a limiting groove 201 is also provided on the placement plate 2, and a receiving plate 23 is provided on the side of the movable frame 3 close to the placement plate 2 in an upper and lower symmetrical structure, and a motor 11 is provided on the upper receiving plate 23, and a cutting wheel is connected and fixed to the output end of the motor 11 12, a plurality of sliding cylinders 20 are embedded in the receiving plates 23 located on both sides of the cutting wheel 12, a guide rod 21 is provided on the sliding cylinder 20, a pressure stone 6 is provided at one end of the guide rod 21, a driving mechanism and a transmission mechanism are also provided on the movable frame 3, the driving mechanism can drive the receiving plates 23 on both sides to move in the opposite direction through the transmission mechanism, a clamping assembly 7 is provided on the lower side of the placing plate 2, the clamping assembly 7 includes two clamping plates 701 slidably connected to the cutting groove 202 in a symmetrical structure and a driving mechanism, the driving mechanism can drive the clamping plates 701 on both sides to move in the opposite direction.

[0035] In this embodiment, the staff places the stone slab to be cut on the top surface of the placement plate 2, and places the position of the stone slab to be cut under the cutting wheel 12. Then, under the drive of the driving mechanism, the clamping plate 701 moves from both sides to the middle to fix the stone slab. Then, under the action of the motor 11, the cutting wheel 12 rotates. Under the action of the driving mechanism and the transmission mechanism, the receiving plate 23 drives the cutting wheel 12 to move downward, and the stone pressing block 6 is pressed on the travel position of the cutting wheel 12 on the stone slab to prevent the stone slab from vibrating during the cutting process and preventing the stone slab from collapsing. Then, the staff slides the moving frame 3 to cut the stone slab.

[0036] Specifically, Figure 2 As shown, the driving mechanism includes an electric push rod 10 arranged on the mobile frame 3, and the output end of the electric push rod 10 is connected and fixed to one of the receiving plates 23.

[0037] In this embodiment, under the action of the electric push rod 10, the receiving plate 23 connected thereto can move upward or downward.

[0038] Further, such as Figure 2 As shown, the transmission mechanism includes a fixed shaft 14 arranged on the mobile frame 3, a gear 15 is sleeved and fixed on the fixed shaft 14, and two racks 16 meshing and connected to the gear 15 are arranged on both sides of the gear 15 in a centrally symmetrical structure, and the racks 16 are connected and fixed to the corresponding receiving plates 23.

[0039] In this embodiment, when the receiving plate 23 on one side moves toward the gear 15, the receiving plate 23 on the other side simultaneously moves toward the gear 15 due to the meshing connection between the rack 16 and the gear 15, so that the two receiving plates 23 move in opposite directions.

[0040] Further, if Figure 3 As shown, the guide rod 21 is slidably connected to the sliding cylinder 20 , and a first spring 26 connected and fixed to the sliding cylinder 20 is provided at the upper end of the guide rod 21 .

[0041] In this embodiment, the purpose of providing the first spring 26 is to make the stone pressing block 6 have a certain elasticity, so as to effectively prevent the stone pressing block 6 from causing damage to the stone slab when the surface of the stone slab is rough and uneven.

[0042] Furthermore, the inner end of the pressure stone block 6 is densely covered with a plurality of rubber balls 27 .

[0043] In this embodiment, the purpose of providing the rubber balls 27 is to reduce friction, so that the workers can cut the stone slabs smoothly and quickly.

[0044] It is worth noting that see Figure 2 The receiving plate 23 is provided with a first screw rod 17 which is limited by the receiving plate 23 and rotatably connected thereto. The first screw rod 17 is threadedly connected with a movable plate 19 which is fixedly connected to the sliding cylinder 20. The receiving plate 23 is also provided with a limiting rod 18 which is slidably connected to the movable plate 19.

[0045] In this embodiment, during the cutting of the stone slab, the staff rotates the first screw 17, and the moving plate 19 then drives the sliding cylinder 20 and the stone pressing block 6 to move, thereby changing the pressing force of the stone pressing block 6 on the stone slab, thereby improving the practicality of the device.

[0046] It is worth noting that Figure 5As shown, the driving mechanism includes a fixed frame 704 arranged on the lower side of the placement plate 2 and a cylinder 702 arranged on the lower side of one of the clamping plates 701, the output end of the cylinder 702 is connected and fixed to the fixed frame 704, a connecting plate 703 is rotatably connected to the fixed frame 704, and connecting rods 705 rotatably connected to the clamping plate 701 are rotatably connected on both sides of the connecting plate 703.

[0047] In this embodiment, under the action of the cylinder 702, the splint 701 connected to the cylinder 702 moves inward, and under the action of the corresponding connecting rod 705, the connecting plate 703 rotates, and under the connection of the connecting rod 705 on the other side, the splint 701 on the other side follows and moves inward to clamp the stone slab.

[0048] In addition, Figure 4 As shown, a fixing plate 4 is also provided on the placement plate 2, a limiting plate 5 is provided on the side of the fixing plate 4 close to the cutting groove 202, and a plurality of second springs 13 connected and fixed to the fixing plate 4 are provided on the side of the limiting plate 5 close to the fixing plate 4.

[0049] In this embodiment, one end of the stone slab is pressed against the limiting plate 5, and the second spring 13 contracts immediately, which can limit the stone slab to a certain extent, further reduce vibration, and prevent edge collapse.

[0050] In addition, see Figure 6 The limiting plate 5 and the splint 701 are both provided with a pressure plate assembly 9 for fixing the stone to be cut. The pressure plate assembly 9 includes a clamping plate 903 and a driving assembly arranged on the limiting plate 5 and the splint 701. The clamping plate 903 is limited by the corresponding limiting plate 5 and the splint 701 and is slidably connected with the corresponding limiting plate 5 and the splint 701. The driving assembly can drive the clamping plate 903 to move up and down.

[0051] In this embodiment, driven by the driving component, the clamping plate 903 moves downward until the clamping plate 903 is in close contact with the stone slab, further fixing the stone slab, preventing the stone slab from swinging sideways, further reducing vibration, and further reducing the probability of edge collapse of the stone slab.

[0052] In addition, the driving assembly includes a bearing plate 902 connected and fixed to the corresponding limiting plate 5 and the clamping plate 701 , and a second screw rod 901 is threadedly connected to the bearing plate 902 and is restricted by the clamping plate 903 and rotatably connected thereto.

[0053] In this embodiment, the staff rotates the second screw rod 901, and the second screw rod 901 can drive the pressing plate 903 to move.

[0054] The present invention also provides another driving component, which includes an electric push rod 2 for pushing the clamping plate 903 up and down, the fixed end of the electric push rod 2 is connected and fixed to the limiting plate 5 and the clamping plate 701, the movable end of the electric push rod 2 is connected and fixed to the clamping plate 903, and two pressure sensors are provided on the limiting plate 5. The electric push rod 2 and the cylinder 702 both respond to the signals of the pressure sensors.

[0055] In this embodiment, the pressure signal collected by the pressure sensor is transmitted to the controller. The controller determines and controls whether the electric push rod 2 and the cylinder 702 are in motion according to the relationship between the pressure signal values ​​of the two pressure sensors. The ratio of the two pressure values ​​is set by the controller:

[0056] When both pressure values ​​are zero, it means that the stone plate has not yet contacted the limiting plate 5;

[0057] When one of the pressure values ​​is not zero, it means that only part of the stone slab is in contact with the limiting plate 5, and the stone slab needs to be pushed forward;

[0058] When both pressure values ​​are not zero and the ratio of the two pressure values ​​is not less than the set value, it means that the pressures at different positions of the limiting plate 5 are different, causing the limiting plate 5 to deflect. If the stone slab is cut in this case, the cutting edge will be deflected compared with the edge of one side of the stone slab, so the stone slab needs to be moved further;

[0059] When both pressure values ​​are not zero and the ratio of the two pressure values ​​is less than the set value, it indicates that one edge of the stone slab is in full contact with the limiting plate 5. At this time, the electric push rod provided on the limiting plate 5 is controlled to move the clamping plate 903 downward to fix one side of the stone slab. Then, the cylinder 702 is controlled to move the two clamping plates 701 inward at the same time to clamp the stone slab. Then, the electric push rods on the two clamping plates 701 are controlled to move further to clamp both sides of the stone slab to stably fix the stone slab.

[0060] In this embodiment, a conveyor belt can be arranged in the placement plate 2, and the conveyor belt is located between the two clamping plates 701. The stone slab is transported by the conveyor belt. When the edge of one side of the stone slab is fully in contact with the limiting plate 5, the driving part of the conveyor belt is first controlled to stop working so that the stone slab does not move, and then the subsequent clamping and fixing operation is performed. With the close cooperation of the two pressure sensors, the electric push rod 2, and the cylinder 702, one side of the stone slab can be automatically adjusted and fully fit the limiting plate 5, so that the cutting edge is parallel to one side of the stone slab, which is particularly suitable for irregular stone slab cutting.

[0061] Furthermore, a pressure sensor is provided in the middle of the pressing plate 903 on the clamping plate 701 , and the alarm included in the stone cutting device responds to the signal of the pressure sensor provided in the middle of the pressing plate 903 .

[0062] In this embodiment, when cutting a stone slab with a regular rectangular structure, the two opposite sides of the stone slab are completely clamped in the clamping plate 701. At this time, the pressure values ​​measured by the two pressure sensors arranged in the middle are not zero. When cutting stone slabs with irregular structures, after the electric push rods on the limiting plate 5 and the clamping plate 701 have been actuated to achieve clamping and fixing, when the pressure values ​​of the two pressure sensors are not zero, the electric push rod 10 and the motor 11 are controlled to actuate to cut the stone slab; when the pressure value of only one of the pressure sensors is not zero, it indicates that of the two opposite edges of the stone slab, one side is clamped in the clamping plate 701 for more than half, while the other side is less than half. At this time, there is a relatively low risk of edge collapse, and the control alarm is controlled to sound a short alarm, but the electric push rod 10 and the motor 11 are still controlled to actuate to cut the stone slab; when the pressure values ​​of the two pressure sensors are both zero, it indicates that the two opposite edges of the stone slab are clamped in the clamping plate 701 for less than half, and there is a relatively high risk of edge collapse, and the control alarm is controlled to sound a long alarm, and the electric push rod 10 and the motor 11 are controlled not to actuate, and the staff is allowed to come forward to check and determine whether to continue cutting.

[0063] Through the above design, the anti-collapse edge clamping and cutting of the stone slab can be carried out automatically and orderly, and the stone slab cutting device can achieve integrated control.

[0064] In addition, Figure 2 As shown, a mounting plate 24 is provided on one of the receiving plates 23, a nozzle 22 is embedded on the mounting plate 24, and one end of the nozzle 22 is connected to a hose 25 connected to an external water supply device.

[0065] In this embodiment, when the cutting wheel 12 cuts the stone slab, the nozzle 22 sprays water to the stone slab and the cutting wheel 12 to reduce dust and temperature, thereby avoiding the edge collapse caused by the stone slab and the cutting wheel 12 being too hot.

[0066] In addition, Figure 7 As shown, a fixing clamp 8 connected and fixed to the placing plate 2 is provided at the rear side of the cutting groove 202, and a sharpening block 28 is provided in the middle of the fixing clamp 8, and the sharpening block 28 is made of refractory bricks.

[0067] In this embodiment, after the stone slab is cut, the movable frame 3 is continuously moved to make the cutting wheel 12 contact with the grinding block 28, so as to grind the cutting wheel 12 to ensure a sharp cutting edge and avoid edge collapse.

[0068] When the relevant staff needs to use the device to cut the stone slab, the staff first places the stone slab to be cut on the top surface of the placement plate 2, and places the position of the stone slab to be cut on the lower side of the cutting wheel 12. The side close to the limiting plate 5 is abutted against the outer wall of the limiting plate 5, and the second spring 13 is then contracted, which can limit the stone slab to a certain extent. Then, under the action of the cylinder 702, the clamping plate 701 connected to the cylinder 702 moves inward, and under the action of the corresponding connecting rod 705, the connecting plate 703 rotates, and under the connection of the connecting rod 705 on the other side, the clamping plate 701 on the other side follows and moves inward to clamp the stone slab.

[0069] Then the staff rotates the second screw rod 901, and the second screw rod 901 drives the pressing plate 903 to move downward until the pressing plate 903 is in close contact with the stone slab, thereby further fixing the stone slab.

[0070] Then, under the action of the motor 11, the cutting wheel 12 rotates. Under the action of the electric push rod 10, the receiving plate 23 connected thereto moves downward. Since the rack 16 is meshed and connected with the gear 15, the receiving plate 23 on the other side moves upward. The stone pressing block 6 and the cutting wheel 12 move accordingly, and the stone pressing block 6 is pressed on the travel position of the cutting wheel 12 on the stone slab, and then the staff slides the moving frame 3 to cut the stone slab.

[0071] During this period, the nozzle 22 sprays water to the stone slab and the cutting wheel 12 to reduce dust and temperature. After the stone slab is cut, the moving frame 3 is moved to make the cutting wheel 12 contact with the sharpening block 28, so that the cutting wheel 12 can be polished to ensure the sharp cutting edge.

[0072] During the process of cutting the stone slab, when the staff needs to change the pressing force of the stone pressing block 6 on the stone slab, the staff rotates the first screw rod 17, and the moving plate 19 then drives the sliding cylinder 20 and the stone pressing block 6 to move, thereby changing the pressing force.
