Description

Technical Field

[0001] The invention belongs to the technical field of cutting equipment, and in particular relates to a cutting equipment for building engineering materials. Background Art

[0002] Building materials are various materials used in construction projects. There are many types of building materials, which can be roughly divided into inorganic materials, organic materials, composite materials, etc. Among them, stone is the most common material in building materials. In many engineering projects such as construction and decoration, stone needs to be cut into precise sizes according to design requirements. For example, a construction material cutting device is proposed in patent announcement number CN113941731B.

[0003] In the process of cutting stone, since the stone itself has a certain hardness and the hardness of different types of stone varies greatly, when the cutting disc cuts a stone with a higher hardness, such as granite, the stone will produce a large friction resistance to the blade or abrasive of the cutting disc, so that the cutting blade or abrasive particles on the surface of the cutting disc are constantly worn and consumed during the continuous cutting process, resulting in wear of the cutting disc. Even when cutting stones with relatively low hardness, long-term cutting operations will gradually wear the cutting disc due to continuous friction. As the degree of wear of the cutting disc deepens, the uneven wear problem that may have existed will be magnified. For example, at first only a part of the stone wears faster. When the wear is serious, this difference will become extremely significant, resulting in greater differences in the thickness and shape of the various parts of the edge of the cutting disc, making it difficult for the cutting disc to maintain a stable cutting trajectory during cutting, and then the inclination of the cutting gap is aggravated. The operator can only detect the degree of wear of the cutting disc after all the stone cutting is completed, which leads to uneven cutting surfaces of a large number of stones, affecting the cutting quality.

The positioning electric push rod 30 The movable end is fixedly connected with a rough block 31, and the upper inner wall of the transverse cylinder 281 is inlaid with a rough plate 32 that matches the rough block 31; the positioning assembly 33 includes two small linear motors 331 and two curved rods 332, the two small linear motors 331 are symmetrically fixedly connected to the left and right sides of the lower side wall of the cylinder 19, the curved rods 332 are fixedly connected to the movable end of the small linear motor 331, the lower end of the curved rod 332 is fixedly connected with a vertical plate 34, the side wall of the vertical plate 34 away from the curved rod 332 is fixedly connected with a square plate 35, the square plate 35 is rotatably connected to a rotating frame 36, and the rotating frame 36 is connected to the rotating frame 36. A contact block 37 is fixedly connected to the side wall of the frame 36 away from the vertical plate 34, two springs are fixedly connected between the vertical plate 34 and the contact block 37, a round cover 38 is fixedly connected to the front side wall of the contact block 37, a vertical rod 39 is rotatably connected to the center of the round cover 38, a conductive block 40 is fixedly connected to the lower end of the vertical rod 39, and the conductive block 40 is electrically connected to an external power supply, two arc-shaped resistor plates 41 are embedded in the inside of the round cover 38, and the ends of the two arc-shaped resistor plates 41 away from each other are electrically connected to the PLC controller 3, and a micro electric push rod 42 is fixedly connected to the upper inner wall of the round cover 38. The movable end of the electric push rod 42 is fixedly connected with an arc plate 43. Before grinding the cut surface of the stone, the position of the grinding component 13 can be automatically adjusted so that the grinding component 13 is located in the middle of the two cut surfaces, so that the cut surfaces on both sides can be grinded synchronously, and in the process of positioning the grinding component 13, the flatness of the cut surface is automatically detected. When it is detected that the cut surface of the stone is tilted due to the wear of the cutting disk 12, the operator can be reminded in time to replace the cutting disk 12, thereby ensuring the working performance of the cutting equipment.

[0033] The upper side wall of the push plate 48 is fixedly connected with a transverse plate 49, the side wall of the transverse plate 49 is fixedly connected with a clamping electric push rod 50, and the movable end of the clamping electric push rod 50 is fixedly connected with a pressing plate 51, which can ensure the stability of stone placement when cutting the stone.

[0034] A laser receiver 52 is fixedly connected to the lower side wall of the motor box 16 , and the laser receiver 52 is electrically connected to the PLC controller 3 . A laser transmitter 53 is fixedly connected to the upper side wall of the cylinder 19 , and the placement angle of the positioning component 33 can be adjusted.

[0035] The operating principle of the present invention is now described as follows: the stone is placed on the surface of the driving roller 6, and then the operator controls the clamping electric push rod 50 to work through the control box 2, and the clamping electric push rod 50 drives the pressure plate 51 to move downward, and the pressure plate 51 is used to press the stone below. A pressure sensor is provided under the pressure plate 51. When the pressure sensor detects that the extrusion force between the pressure plate 51 and the stone reaches a set threshold, the pressure sensor will control the clamping electric push rod 50 to stop working through the PLC controller 3, so that the stone can be fixed vertically. Then the operator controls the working motor 45 to work through the control box 2, and the working motor 45 drives the threaded column 442 to rotate, and drives the threaded ring 46 to move through the threaded fit, and the threaded ring 46 drives the push rod 47 to move, so that the push rod 47 drives the push plate 48 to move, and the push plate 48 pushes the stone on the upper side of the transmission roller 6 to move. At this time, the pressure plate 51 limits the stone, thereby preventing the stone from being deviated during transportation. A proximity switch is provided on the lower side of the mounting frame 8 (the proximity switch is an existing mature technology and is not described in detail in this article). When the proximity switch detects that the stone moves to the set distance, the working motor 45 will be controlled to stop working through the PLC controller 3, so that the left end of the stone is aligned with the cutting disc 12;

[0036] Then the PLC controller 3 will control the working motor 45 to work for the set time according to the cutting demand. Referring to the above principle, the stone can be pushed to the left by a set distance (for example, the working motor 45 works for one second to control the stone to move 5 cm. When a stone of 20 cm in length needs to be moved, the PLC controller 3 will control the working motor 45 to work for four seconds to cut a stone of 20 cm in length). Then the PLC controller 3 controls the first electric push rod 91 and the cutting motor 11 to work at the same time. The first electric push rod 91 will drive the first linear motor 92 and the cutting disc 12 to move downward to the set position. Then the PLC controller 3 controls the first linear motor 92 to work. The first linear motor 92 drives the cutting disc 12 to move from front to back, so as to cut the stone below.

[0037] When the stone cutting is completed, the PLC controller 3 will control the cutting motor 11 to stop working, and control the first electric push rod 91 to drive the cutting disc 12 to move upward to the initial position. At the same time, the PLC controller 3 will control the conveyor belt mechanism 7 to work, and the conveyor belt mechanism 7 drives the cut section of stone to move a certain distance to the left, so that a certain distance is maintained between the two cutting surfaces of the stone. Then the PLC controller 3 controls the second electric push rod 131 to work, and drives the transverse electric push rod 15 and the cylinder 19 to move downward together through the second electric push rod 131. At the same time, the PLC controller 3 will also control the transverse electric push rod 15 to work, so that the cylinder 19 moves to a position above the two cutting surfaces, and the positioning component 33 is located between the two cutting surfaces. The PLC controller 3 controls the small linear motors 331 on the left and right sides to work simultaneously. The small linear motors 331 will drive the two vertical plates 34 and the contact blocks 37 to move through the bending rod 332. When the cylinder 19 is not in the middle of the two cutting surfaces, one of the contact blocks 37 will first contact the cutting surface on one side and push the cylinder 19 in the other direction. The cylinder 19 drives the transverse block 282 to slide in the transverse box through the connecting frame 18, the motor box 16 and the guide rod 29 until the contact blocks 37 on both sides are in contact with the cutting surface (the side walls of the two contact blocks 37 are provided with pressure sensors). The pressure sensors on the surfaces of the two contact blocks 37 will detect the gradually increasing extrusion pressure. When the PLC controller 3 detects the two contact blocks through the pressure sensors, When the extrusion pressure between the side contact block 37 and the cutting surfaces on both sides reaches the set threshold, the positioning electric push rod 30 will be immediately controlled to drive the rough block 31 to move upward a certain distance, so that the rough block 31 contacts the rough plate 32, and the position of the transverse block 282 is fixed by the friction between the rough block 31 and the rough plate 32. The transverse block 282 fixes the positions of the motor box 16, the connecting frame 18 and the cylinder 19 through the guide rod 29. Then the PLC controller 3 will control the servo motor 21 to work, and control the small linear motors 331 on both sides to drive the contact block 37 to separate from the cutting surface and restore it to the initial position. The servo motor 21 drives the threaded rod 20 to rotate, and drives the two threaded cylinders 22 to move towards each other through the threaded cooperation. The cylinder 22 controls the movement of the connecting block 23 through the cooperation between the hinge frame 24 and the rotating rod 25, and uses the connecting blocks 23 on both sides to drive the grinding blocks 26 to move outward, so that the grinding blocks 26 on both sides contact the cut surface of the stone. When the PLC controller 3 detects through the pressure sensor 27 that the pressure value between the grinding block 26 and the cut surface of the stone reaches the set threshold, the PLC controller 3 will control the servo motor 21 to stop working, and control the grinding motor 17 and the second linear motor 132 to work. The grinding motor 17 drives the cylinder 19 to rotate through the connecting frame 18, and the cylinder 19 drives the surface grinding block 26 to rotate. The second linear motor 132 drives the rotating grinding block 26 to move backward, and uses the grinding block 26 to grind the cut surface of the stone.

[0038] When the cutting disc 12 is worn, as the degree of wear of the cutting disc 12 deepens, the uneven wear problem that may have existed will be magnified. For example, at first only a part will wear faster. When the wear is serious, this difference will become extremely significant, resulting in greater differences in the thickness and shape of the edge parts of the cutting disc 12, making it difficult for the cutting disc 12 to maintain a stable cutting trajectory during cutting, and then the inclination of the cutting gap is aggravated, making the cutting surface of the stone uneven. After the contact block 37 contacts the uneven cutting surface, the contact block 37 will fit the uneven contact surface, and the contact block 37 will drive the circular cover 38 to rotate a certain angle along the hinge between the square plate 35 and the rotating frame 36, and the vertical rod 39 inside the circular cover 38 will drive the conductive block 40 to always remain in a vertical state under the action of gravity, and the circular cover 38 will drive the arc-shaped resistor plates 41 on both sides to rotate a certain angle. The conductive block 40 is arranged at a fixed angle so that the conductive block 40 contacts the arc-shaped resistor plate 41 on one side, and when the wear of the cutting disk 12 is more serious, the inclination angle of the stone cutting surface is larger, and the inclination angle of the arc-shaped resistor plate 41 driven by the round cover 38 is larger, and the conductive block 40 will contact the position of the arc-shaped resistor plate 41 near the upper end, and the conductive block 40 is electrically connected to the external power supply, and the upper end of the arc-shaped resistor plate 41 contacts the PLC controller 3. When the conductive block 40 contacts the arc-shaped resistor plate 41, an electrical signal is transmitted to the PLC controller 3. The PLC controller 3 drives the warning element on the surface of the control box 2 to work according to the size of the electrical signal transmitted by the arc-shaped resistor plate 41 (the warning element can be a variety of sound and light alarms, and the different degrees of wear of the cutting disk 12 can be displayed by sound and light alarms of different colors), so that the operator can know the degree of wear of the cutting disk 12 and replace it in time.
