[0022] A sawing device comprises a frame 1, a first feeding mechanism 2, a second feeding mechanism 3, a sawing mechanism 4 and a turning mechanism 5. The first feeding mechanism 2, the second feeding mechanism 3, the sawing mechanism 4 and the turning mechanism 5 are all arranged on the frame.

[0023] The frame 1 is a frame structure formed by welding pipe fittings, and one end of the frame 1 is defined as a material feeding end. The first feeding mechanism 2 is arranged close to the material feeding end, and the second feeding mechanism 3 and the first feeding mechanism 2 are arranged at intervals along the material conveying direction and are arranged away from the material feeding end.

[0024] The first feeding mechanism 2 and the second feeding mechanism 3 both include a fixing plate 31, a clamping mechanism 32, a gear transmission mechanism 33 and a pulley mechanism 34. The specific structure of the clamping mechanism 32 can be found in the utility model patent with application number 202320495594.2, which will not be repeated here.

[0025] The gear transmission mechanism 33 includes a first driving device 331, a transmission shaft 332, a first transmission gear 333, a second transmission gear 334, a moving gear 335 and a rack 336. The first driving device 331 can be a motor, the first transmission gear 333 and the second transmission gear 334 are meshed with each other, the second transmission gear 334 and the moving gear 335 are both arranged on the transmission shaft 332, and the moving gear 335 and the rack 336 are meshed with each other. When working, the first driving device 331 drives the first transmission gear 333 to rotate, including forward and reverse rotation, thereby driving the second transmission gear 334 to rotate, and the rotation of the second transmission gear 334 drives the transmission shaft 332 to rotate. Since the moving gear 335 is also arranged on the transmission shaft 332, it drives the moving gear 335 to rotate, thereby driving the entire first feeding mechanism 2 and the second feeding mechanism 3 to translate along the rack 336, that is, the first feeding mechanism 2 and the second feeding mechanism 3 reciprocate along the material conveying direction.

[0026] The pulley mechanism 34 includes a transverse pulley 341 and a longitudinal pulley 342 , and the transverse pulley 341 and the longitudinal pulley 342 cooperate with each other to ensure the smooth displacement of the first feeding mechanism 2 and the second feeding mechanism 3 .

The third transmission gear 42 and the fourth transmission gear 43 are meshed with each other. The fourth transmission gear 43 is preferably a fan gear. The fourth transmission gear 43 is fixedly mounted on the rotating shaft 44. One end of the transmission arm 45 is fixedly connected to the rotating shaft 44, and the other end is fixedly connected to the third driving device 46. When working, the second driving device 41 drives the third transmission gear 42 to rotate, including forward and reverse rotation. The third transmission gear 42 drives the fourth transmission gear 43 to rotate, and then drives the rotating shaft 44 to rotate. Since the two ends of the transmission arm 45 are respectively fixedly connected to the rotating shaft 44 and the third driving device 46, the rotation of the rotating shaft 44 drives the transmission arm 45, the third driving device 46 and the saw blade 47 to rotate around the rotating shaft 44 to complete the advance and retreat.
