[0002] The saw table lifting device of a sawing machine is an important part of the sawing machine for adjusting the distance between the saw blade and the workpiece, which ensures the flexibility and accuracy of the sawing operation. Through the lifting device, the distance between the saw blade and the workpiece can be conveniently adjusted, thereby controlling the sawing depth. For materials with different thicknesses and hardnesses, the lifting device can ensure that the saw blade saws at an appropriate angle and depth. By quickly and accurately adjusting the height of the saw table, the idle cutting time during the sawing process can be reduced, and the sawing efficiency can be improved. Among them, the saw table lifting device of the sawing machine can use the telescopic movement of a hydraulic cylinder to realize the lifting of the saw table. Hydraulic lifting has the advantages of fast speed, large force, and simple operation, and is widely used. However, a large amount of debris and dust will be generated when the sawing machine is in use. Since the piston rod of the hydraulic cylinder is exposed outside, when the piston rod extends and retracts, it will come into contact with the external environment, and debris and dust may adhere to the piston rod. Once the debris enters the hydraulic cylinder, it may affect the normal operation of the hydraulic system, such as blocking the oil circuit, wearing the seals, and aggravating the wear of the cylinder body, which has certain deficiencies.

A first groove 201 and a second groove 202 are successively provided on the outer side of the hydraulic cylinder 200. Gaskets for fixing are provided at the top and bottom of the hydraulic cylinder 200, and a connecting pipe for the inlet and outlet of hydraulic oil is provided outside the hydraulic cylinder 200. During use, the connecting pipe of the hydraulic cylinder 200 can be connected to a hydraulic oil supply device, and the telescoping is controlled by controlling the inlet and outlet of hydraulic oil, so as to drive the saw table main body 300 to lift.

[0028] Specifically, the saw table main body 300 is bolted to the top of the hydraulic cylinder 200. During use, the telescoping of the hydraulic cylinder 200 can drive the saw table main body 300, so as to lift.

[0029] Specifically, the first dustproof component 400 includes a first elastic band 401 inserted in the first groove 201, a first dustproof cloth 402 sewn on the outside of the first elastic band 401, and a second elastic band 403 sewn at the bottom of the first dustproof cloth 402 and inserted and connected with the second groove 202. The first elastic band 401 and the second elastic band 403 have the same structure, and the first elastic band 401 and the second elastic band 403 are ring-shaped.
