In the process of cutting the polyurethane aluminum alloy composite insulation profile by the cutting disc 805 and the cutting teeth 806, the clamping plate 1107 is always in a clamping state against the polyurethane aluminum alloy composite insulation profile. The partially atomized cutting fluid and airflow entering the protective cover 802, one part will enter the connecting tube 1101 on one side, and the other part will pass through the storage groove 807 and enter the connecting tube 1101 on the other side, and then be transported to the slide rod 1104 under the action of the connecting tube 1102, and then enter the clamping plate 1107 through the slide tube 1105, and finally sprayed to the cutting disc 805, the cutting teeth 806 and the two sides of the cutting part of the polyurethane aluminum alloy composite insulation profile through the injection hole 1108, further cooling the cutting disc 805, the cutting teeth 806 and the cutting part, thereby ensuring the cutting efficiency and quality.

[0029] The specific working principle of the present invention is as follows: When in use, the polyurethane aluminum alloy composite heat-insulating profile to be cut is placed in the grooves provided on the top of the supporting plate 2 and the supporting rod 4, and the cutting position of the polyurethane aluminum alloy composite heat-insulating profile is aligned with the cutting teeth 806, and then the motor 803 can be started, so that the motor 803 drives the cutting disc 805 to rotate through the rotating shaft 804, and then drives the cutting teeth 806 to rotate, and then the electric telescopic rod 801 can be started, so that the rotating cutting disc 805 and the cutting teeth 806 move toward the polyurethane aluminum alloy composite heat-insulating profile; When the motor 803 is started, the pump body 902 is started at the same time, so that the pump body 902 draws the cutting fluid in the liquid tank 901 into the liquid injection pipe 904 through the connecting hose 903, and then is atomized by the atomizing nozzle and sprayed to the fan blade 1006, and the fan blade 1006 also blows the atomized cutting fluid and the extracted gas to the cutting disk 805 at the same time, so that part of the cutting fluid is absorbed by the sponge 808, and the other part of the cutting fluid enters the protective cover 802, so as to cool the cutting disk 805, thereby well protecting the cutting disk 805, and at the same time The cutting fluid is sprayed outward through the cutting disc 805 and acts on the working surface. The cutting fluid that enters the sponge 808 is discharged from the chip discharge port 810 through the injection channel 809 under the action of the centrifugal force generated by the rotation and cutting of the cutting disc 805, thereby promoting the chip discharge ability between the cutting teeth 806 and protecting the cutting teeth 806 well, thereby extending the service life of the cutting teeth 806. In addition, the cutting fluid can directly act on the cutting part between the cutting teeth 806 and the polyurethane aluminum alloy composite insulation profile, thereby cooling the cutting part and ensuring the cutting quality. At the same time, the rotation of the rotating shaft 804 will drive the second synchronous wheel 1009 to rotate, and the second synchronous wheel 1009 will drive the rotating rod 1005 to rotate through the synchronous belt 1008 and the first synchronous wheel 1007, thereby rotating the fan blade 1006, so that the air inlet end of the U-shaped tube 1001 produces a suction effect, extracting the chips remaining on the cutting teeth 806 between the air inlet end and the suction hole of the U-shaped tube 1001, and allowing the air to act on the cutting teeth 806 to cool down the cutting teeth 806, and the extracted chips will enter the filter cartridge 1003, and the chips generated by the extraction The airflow will impact between the cutting disc 805 and the protective cover 802. A part of the airflow enters the air inlet end of the U-shaped tube 1001, which further improves the chip removal capability of the circular cutter. The other part is discharged through the protective cover 802, which blocks a part of the chips generated by cutting from entering the protective cover 802, thereby improving the chip removal capability of the circular cutter and reducing the probability of chips entering the protective cover 802, thus protecting the circular cutter and improving the cutting efficiency. In addition, the cutting disc 805 can be cooled to avoid excessive temperature during cutting, which will increase the wear of the cutting disc 805 and affect the service life of the cutting disc 805. And when the electric telescopic rod 801 begins to extend, the clamping plate 1107 will first contact the polyurethane aluminum alloy composite thermal insulation profile. Before the cutting disc 805 and the cutting teeth 806 contact the polyurethane aluminum alloy composite thermal insulation profile, the clamping plate 1107 gradually compresses the polyurethane aluminum alloy composite thermal insulation profile through the sliding rod 1104, the sliding cylinder 1105 and the clamping spring 1106. During this process, part of the atomized cutting fluid and airflow entering the protective cover 802 will enter the connecting tube 1101 on one side, and the other part will pass through the storage groove 807 and enter the connecting tube 1101. Then, under the action of the connecting tube 1102, they are respectively transported to the sliding rod 1104, and then enter the clamping plate 1107 through the sliding cylinder 1105, and finally blow to the upper surface of the polyurethane aluminum alloy composite thermal insulation profile through the injection hole 1108, so as to remove impurities on the upper surface of the polyurethane aluminum alloy composite thermal insulation profile and prevent the impurities from affecting the cutting quality. During the process of the cutting disc 805 and the cutting teeth 806 cutting the polyurethane aluminum alloy composite heat insulating profile, the pressing plate 1107 is always in a pressing state against the polyurethane aluminum alloy composite heat insulating profile, and part of the atomized cutting fluid and airflow entering the protective cover 802 will enter the connecting tube 1101 on one side, and the other part will pass through the storage groove 807 and enter the connecting tube 1101 on the other side, and then be transported to the slide rod 1104 respectively under the action of the connecting tube 1102, and then enter the pressing plate 1107 through the slide tube 1105, and finally sprayed to the cutting disc 805, the cutting teeth 806 and the two sides of the cutting part of the polyurethane aluminum alloy composite heat insulating profile through the injection hole 1108, so as to further cool the cutting disc 805, the cutting teeth 806 and the cutting part, thereby ensuring the efficiency and quality of cutting; During the cutting process, the waste liquid and chips generated may enter the collection box 3, and the filter box 5 will filter the waste liquid and chips, so that the chips remain in the filter box 5, and the waste liquid will be stored in the collection box 3. When the chips and waste liquid need to be processed, the filter box 5 is pulled out of the collection box 3, and the chips remaining in the filter box 5 can be processed. The waste liquid in the collection box 3 can be discharged for processing by opening the valve in the drain pipe; After the cutting is completed, turn off the motor 803, and then start the electric telescopic rod 801, so that the cutting disk 805 and the cutting teeth 806 can be reset, and then the clamping plate 1107 can be reset, and the cut polyurethane aluminum alloy composite insulation profile can be taken out from the grooves on the top of the supporting plate 2 and the supporting rod 4 to proceed to the next step. The operation is simple, fast and convenient to use. During this process, since the temperature of the cutting disk 805 is still high, in order to reduce the oxidation of the cutting disk 805 under the action of temperature, the pump body 902 is still in working state at this time. Although the motor 803 stops working, the atomized cutting fluid can still cool the cutting disk 805 through the multiple holes opened on the fan blades 1006, so as to avoid the cutting disk 805 being at a high temperature when the cutting stops, causing it to oxidize, thereby further protecting the cutting disk 805. After the cutting disk 805 cools down to room temperature, the pump body 902 can be turned off.

[0030] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
