[0074] Embodiment 2:

[0075] The present embodiment provides a band sawing machine, which, in addition to the technical solutions of the above-mentioned embodiments, also has the following technical features: the auxiliary guide member 6 also includes: an auxiliary guide arm 60, which is arranged on the guide crossbeam 21 and located on one side of the saw blade guide member 3, and the bottom end of the auxiliary guide arm 60 is provided with a through slot 61 for the band sawing machine to pass through; a mounting shell 62, which is arranged at the bottom end of the outer wall of the auxiliary guide arm 60, and the mounting shell 62 has an inner cavity connected with the through slot 61; a cylinder body 63, which is fixedly arranged in the inner cavity of the mounting shell 62, and the cylinder body 63 is filled with a shear thickening liquid; a movable block 64, which is movably arranged in the cylinder body 63 by a spring 65, and a surface of the movable block 64 away from the spring 65 is provided with a plurality of connecting rods 66, which pass through the cylinder body 63 and are movably sealed with the cylinder body 63; a roller frame 67, which is movably arranged in the inner cavity of the mounting shell 62, and a rotating roller 68 is arranged in the roller frame 67;

[0091] It also includes: a connecting head 77, the connecting head 77 is used to assist the rotational flow of the cooling liquid;

[0092] The filter tube 74 is connected to the outlet end of the drainage pump 73 through a connecting head 77 .

The spiral guide portion 76 in the filter tube 74 can rotate the coolant when the coolant flows along the filter tube 74. The fine impurities in the coolant that are not fully filtered are therefore gathered at the edge of the coolant under the action of centrifugal force. When the coolant flows to the recovery pipe 75 at the end of the filter tube 74, the center of the coolant is directly discharged through the recovery pipe 75, while the impurities at the edge of the coolant gradually settle downward to the side of the filter tube 74 that is bent downward. At the same time, through the setting of the connecting head 77, the coolant first enters the transfer chamber 771 when being transported from the discharge pipe 72 to the filter tube 74, and then enters the liquid inlet tube body 772 through a plurality of inclined tubes 773. The plurality of inclined tubes 773 enable the coolant to form a rotating state when entering the liquid inlet tube body 772, thereby effectively ensuring the separation effect of the filter tube 74 on fine impurities. Compared with the prior art, the present invention can further improve the recovery effect of the coolant, reduce the content of fine impurities in the coolant, increase the circulation service life of the coolant, and reduce the production cost.
