Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of cutting devices, in particular to an automatic cutting device for fireproof insulation boards. BACKGROUND

[0002] With the development of society, people's living standards are constantly improving, and the construction industry has developed rapidly. There are more and more types of building materials, including fireproof insulation boards.

[0003] After the fireproof insulation board is produced, a cutting device is needed to cut the fireproof insulation board. In order to ensure production efficiency and control labor costs, some fireproof insulation board manufacturers will use an automatic cutting device to cut the fireproof insulation board after producing the fireproof insulation board. For example, a cutting device for processing basalt fireproof insulation boards is proposed in patent number CN214924892U.

[0004] The existing automatic cutting device has the following disadvantages when in use:

[0005] When the automatic cutting device is in use, the saw disc is used to cut the fireproof insulation board. After long-term use, the saw teeth on the surface of the saw disc will be damaged. If a small amount of saw teeth is missing from the surface of the saw disc, it will not affect the normal operation of the saw disc. When there are many missing saw teeth on the surface of the saw disc, the saw disc will not be sharp during sawing. When the saw disc with missing teeth is used to cut the fireproof insulation board, the part of the saw disc with missing teeth will contact the insulation board, which will easily cause the saw disc to vibrate up and down.

[0006] Moreover, the saw disc is clamped and fixed by two flanges. After long-term use of the saw disc, wear will occur between the saw disc and the two flanges, making the flange clamping unstable. When the saw disc rotates at high speed, it is easy to cause the saw disc to vibrate left and right. When the saw disc vibrates, the cutting equipment needs to be stopped for inspection and replacement of the saw disc. Since the cutting device is not manually operated, the operator cannot stop the equipment in time when the saw disc vibrates. After long-term vibration of the saw disc, it is easy to break and splash, which poses a great safety hazard.

[0007] Therefore, we propose an automatic cutting device for fireproof insulation boards to solve the above problems. SUMMARY

[0036] The upper side wall of the moving frame 6 is fixedly connected with a lamp plate 36, the upper side wall of the lamp plate 36 is fixedly connected with a yellow lamp bead 37 and a red lamp bead 38, the conductive plate 18 is electrically connected with the yellow lamp bead 37, and the electric contact block 31 is electrically connected with the red lamp bead 38, the upper side wall of the moving frame 6 is fixedly connected with a buzzer 39, and the conductive plate 18 and the electric contact block 31 are both electrically connected with the buzzer 39, according to different prompting modes, the operator can quickly judge what kind of reason causes the saw disc 22 to shake, and the convenience of the operator in maintenance is improved.

[0037] The lower side wall of the moving frame 6 is fixedly connected with two rows of supporting wheels 40, and the upper side wall of the mounting box 3 is provided with two wheel grooves 41 matched with the supporting wheels 40, so that the supporting capacity of the saw disc 22 and other components can be improved, and the smoothness of the forward and backward movement of the automatic cutting device is improved.

[0038] The operation principle of the present application is as follows: when the cutting device needs to be used, the fireproof insulation board is moved to the position directly below the saw disc 22 through the PLC controller control of the conveying belt 1, then the electric push rod 7 is controlled to move downward through the PLC controller, the electric push rod 7 drives the mounting cover 19 and the saw disc 22 to move downward to the appropriate position, then the first motor 21 and the second motor 402 are controlled to work, the second motor 402 drives the threaded rod 401 to rotate, the threaded rod 401 drives the threaded cylinder 5 to move through the threaded cooperation, the threaded cylinder 5 drives the electric push rod 7 and the saw disc 22 to move forward and backward through the moving frame 6, so that the saw disc 22 can be used to cut the fireproof insulation board;

[0039] When there are more missing teeth on the surface of the saw disc 22, the missing parts will collide with the cutting part of the fireproof insulation board, causing the saw disc 22 to shake up and down. When there are more missing teeth, the saw disc 22 and the cutting part will not contact for a longer time, causing the saw disc 22 to move down to a lower position. When the part with teeth contacts the cutting part, the saw disc 22 will move up again, so as to control the vertical rod 9 and the piston plate 82 to have a large amplitude of shaking in the vertical direction. When the piston plate 82 moves down, the air pressure in the sealed box 81 will decrease, and the external gas will be pushed open by the rubber plate 112 under the action of air pressure, so as to enter the sealed box 81 along the air inlet pipe 10. When the piston plate 82 moves up, the air pressure in the sealed box 81 will increase, and the rubber plate 112 will block the air inlet pipe 10. The rubber plate 112 in the communication pipe 14 will open, allowing part of the gas to enter the sealed cylinder 12. When the gas enters the sealed cylinder 12, the air pressure below the sealing plate 16 will increase, causing the sealing plate 16 to move the conductive block 17 upward until the conductive block 17 and the conductive plate 18 are in contact. The conductive block 17 and the external power source are electrically connected, and the conductive plate 18 and the first electromagnetic block 35 are electrically connected, so that the first electromagnetic block 35 generates magnetism. The first electromagnetic block 35 will attract the first permanent magnet plate 322 to move downward, and the first permanent magnet plate 322 will drive the metal block 33 to move downward, so that the metal block 33 and the metal plate 34 are separated. The metal block 33 and the external power source are electrically connected, and the metal plate 34 is electrically connected with the first motor 21 and the second motor 402 through the timing controller. The timing controller makes the first motor 21 and the second motor 402 continuously disconnected for a period of time, so as to stop the work of the saw disc 22. The conductive plate 18 is electrically connected with the buzzer 39 and the yellow lamp bead 37. When the conductive plate 18 and the conductive block 17 are in contact, the buzzer 39 and the yellow lamp bead 37 will work at the same time, which can remind the operator that the saw disc 22 shakes due to missing teeth, and remind the operator to replace the saw disc 22;

[0040] When the saw disc 22 vibrates due to flange wear, the uneven surface of the flange, even when reinforced with the flange, will cause it to vibrate left and right. This vibration, in turn, causes the mounting cover 19 to vibrate, which in turn causes the conductive rod 232 to vibrate. The conductive rod 232 slides left and right within the horseshoe magnet 231, cutting the magnetic lines of force within the magnet. This generates current within the conductive rod 232, which is electrically connected to the magnetic component inside the electromagnetic relay 26 via a rectifier. The current flowing through the magnetic component causes it to become magnetic, attracting the elastic component and causing the two contacts inside the electromagnetic relay 26 to make contact. This allows external current to enter the second electromagnetic block 29, causing it to become magnetic. The second electromagnetic block 29 attracts the second permanent magnet plate 28 to move, which in turn moves the electric contact plate 30, causing it to contact the electric contact block 31. The electric contact plate 30 is electrically connected to an external power source, and the electric contact block 31 is electrically connected to the first electromagnetic block 35. The first electromagnetic block 35 attracts the first permanent magnet plate 322 to move downwards, which in turn moves the metal block 33 downwards, causing it to separate from the metal plate 34. The metal block 33 is electrically connected to an external power source, and the metal plate 34 is electrically connected to the first motor 21 and the second motor 402 via a timer controller. The timer controller continuously disconnects the first motor 21 and the second motor 402 for a period of time, causing the saw disc 22 to stop working. The electric contact block 31 is also electrically connected to the red LED bead 38 and the buzzer 39, causing them to operate. This alerts the operator that the saw disc 22 is vibrating due to flange wear, prompting them to replace or repair the flange.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
