[0025] Cutting mechanism: The fixed rod 4 is arranged on the bottom surface of the adjusting block 32, and a driving motor 41 for driving the cutting disc 42 is provided at the bottom of the fixed rod 4. Under the control of the above-mentioned lifting cylinder 2, the lifting height of the cutting disc 42 is adjusted to avoid the waste gas generated during cutting to pollute the working environment; a collecting mechanism is provided on the fixed rod 4 to limit the generated waste gas and collect and process it.

[0026] Collection mechanism: The collection cover 6 is connected to the fixing rod 4 through a reset mechanism, and the collection cover 6 covers the cutting disc 42. In order to collect the exhaust gas generated when the cutting disc 42 is working, a through hole 61 that communicates with the inside and outside is provided on the collection cover 6. A filter screen 9 for separating the fiber dust inside the exhaust gas is provided in the through hole 61. An exhaust fan 10 is provided on the outer wall of the collection cover 6. The exhaust fan 10 and the through hole 61 are adapted to each other, and the two cooperate with each other, and with the cooperation of the filter screen 9, the fiber dust is prevented from flying out. A collection groove 62 is provided in the through hole 61 (on the inner side of the filter screen 9). The collection groove 62 is connected to the outside world, and a collection bucket 12 is slidably connected therein. The collection bucket 12 collects the fiber dust in a centralized manner for subsequent reuse; in order to facilitate the maintenance of the drive motor 41 and the cutting disc 42, positioning grooves 64 are provided on the left and right outer walls of the collection cover 6. The positioning groove 64 is connected to the inside of the collection cover 6, and a cover plate 11 is installed on the positioning groove 64 by bolts. When the internal components need to be maintained, the cover plate 11 is removed.

[0027] In order to limit the collecting bucket 12, a limiting hole 63 connecting the inside and the outside is provided on the collecting groove 62. The limiting bolt 13 threadedly connected to the limiting hole 63 limits the collecting bucket 12 to the outside so that the collecting bucket 12 will not slide out due to the vibration of the cutting disk 42 during use.

[0028] Since the rock wool board has a non-smooth surface, in order to reduce the friction of the collecting cover 6 when it is pressed down, an auxiliary groove 65 is provided on the bottom surface of the collecting cover 6, and a roller 14 is rotatably connected in the auxiliary groove 65. Therefore, during use, the roller 14 contacts the rock wool board to reduce friction.

[0029] In order to enable the collecting hood 6 to compress the rock wool board when working, a fixing plate 5 is fixedly installed on the fixing rod 4, and a through hole 51 which is interconnected up and down is provided on the fixing plate 5, and a positioning rod 7 is provided on the top surface of the collecting hood 6, the positioning rod 7 is adapted to the through hole 51, and a spring 8 is mounted on the positioning rod 7, and the spring 8 is located between the collecting hood 6 and the fixing plate 5. During use, the collecting hood 6 is squeezed by the fixing plate 5.

[0030] The working principle of the utility model is as follows: according to the processing needs, the motor is started to drive the adjusting rod 31 to rotate, thereby controlling the adjustment block 32 to move on the crossbeam 3, and then the lifting cylinder 2 is started to work, so that the collecting hood 6 and the cutting disc 42 are against the top surface of the rock wool board, and then the lifting cylinder 2 continues to lift (under the cooperation of the fixing plate 5 and the fixing rod 4, the positioning rod 7 on the collecting hood 6 slides in the perforation 51, and the fixing plate 5 squeezes the spring 8, so that the collecting hood 6 presses the rock wool board, and at the same time, in order to reduce the friction between the collecting hood 6 and the rock wool board, the roller 14 in the auxiliary groove 65 reduces the friction when the two contact), the driving motor 41 works, drives the cutting disc 42 to rotate, and cuts the rock wool board. At the same time, when the cutting disc 42 is working, the exhaust gas generated is extracted with the assistance of the exhaust fan 10, and the fiber dust in the exhaust gas is separated through the filter screen 9 in the through hole 61, so that the limited dust falls into the collecting bucket 12 of the collecting groove 62.

[0031] When the processing is completed, the limit bolt 13 in the limit hole 63 is unscrewed to release the limit on the collection bucket 12, and then the collection bucket 12 is pulled out for centralized treatment and recycling; when the internal components of the collection cover 6 need maintenance, the cover plate 11 on the positioning groove 64 is unscrewed, the interior is cleaned, and the equipment is checked to see if it is normal.
