Abstract
Description
Technical Field
[0001] This utility model relates to the field of slitting machines, specifically an asphalt roll slitting machine. Background Technology
[0002] Asphalt rolls are a common waterproofing material, mainly composed of asphalt, a base material, and a surface covering material. After the asphalt rolls are produced, different widths of asphalt rolls are required in actual applications, which necessitates the use of a slitting machine. The main function of the asphalt roll slitting machine is to cut the recycled asphalt rolls into strips of the required size for further processing and treatment.
[0003] Existing asphalt roll slitting mechanisms lack a mechanism to absorb the exhaust gases produced during asphalt roll cutting. When cutting asphalt rolls, the temperature of the cutting saw and the asphalt rolls increases due to friction. This increased temperature of the asphalt releases gases that are harmful to the human body, and inhalation of these gases can cause injury. Utility Model Content

An air suction mechanism 1 is provided on the outer wall of the machine cover of the cutting mechanism 2. The air suction mechanism 1 includes a ventilation pipe 101, which is fixedly connected to the machine cover of the cutting mechanism 2. A fixed cylinder 102 is fixed to the bottom end of the ventilation pipe 101. A fixed plate 103 is fixed inside the fixed cylinder 102. A suction motor 104 is fixed to the front surface of the fixed plate 103. The output shaft of the suction motor 104... A fan blade 105 is fixed at one end. An oil guiding mechanism 5 is provided inside the ventilation pipe 101. The oil guiding mechanism 5 includes an oil guiding pipe 501. The front end of the oil guiding pipe 501 is fixedly connected to the outer wall of the machine cover of the cutting mechanism 2. A sleeve rod 13 is provided inside the fixing frame 7. A rotating motor 3 is fixed on the left side of the fixing frame 7. The output shaft of the rotating motor 3 passes through the fixing frame 7 and is fixedly connected to the sleeve rod 13. This can absorb the gas generated when cutting asphalt rolls and avoid causing injury to people. The top and bottom of the fixing plate 103 do not contact the inner upper and lower surfaces of the fixing cylinder 102. This allows for ventilation and allows the gas to be discharged from the rear end of the fixing cylinder 102.
[0023] Furthermore, a circular shell 502 is rotatably connected to the outer wall of the suction motor 104. Two connecting blocks 503 are fixed to the outer wall of the circular shell 502.

The sleeve rod 13 is made of aluminum alloy so that it will not be magnetically attracted. An opening 9 is opened on the left side of the front surface of the fixing frame 7, so that the movable plate 8 can be located inside the opening 9 for easy storage of the movable plate 8. After the asphalt roll is put on, the hydraulic rod 10 is activated. The hydraulic rod 10 extends and pushes the movable plate 8 to rotate. The movable plate 8 rotates the electromagnet 11. The electromagnet 11 is put on the iron block 14, and the electromagnet 11 supports the iron block 14. Electromagnet 11 is sleeved on iron block 14. Sleeve rod 13 and iron block 14 are rotatably connected. When electromagnet 11 is energized, it attracts iron block 14. Iron block 14 is fixed and does not rotate, so it does not affect the rotation of sleeve rod 13.

[0026] Connect the rear end of the fixed cylinder 102 to the exhaust gas treatment device, then start the suction motor 104. The suction motor 104 drives the fan blade 105 to rotate, which creates a negative pressure inside the fixed cylinder 102. The ventilation pipe 101 starts to draw air, which can remove the gas generated when cutting asphalt rolls. The gas passes through the fixed cylinder 102 and enters the exhaust gas treatment device, which can prevent workers from inhaling exhaust gas and causing harm to their bodies.
