Working principle: fig. 1 and fig. 2 are the states of the auxiliary shell 104 and the auxiliary shell roller 105 when the application works, in this state, the saw blade 103 rotates clockwise around the axis of the saw blade 103 in fig. 2, so that the saw blade 103 cuts a workpiece, the balance plate 102 and the auxiliary shell roller 105 are both in contact with the workpiece, in the process of cutting the workpiece, the saw blade 103 rotates at a high speed to generate air flow, the air flow generated by the saw blade 103 brings powder into the auxiliary shell 104, the auxiliary shell 104 guides the air flow and the powder to the position where the dust collecting tube 108 is located, the tail of the auxiliary shell 104 blocks the air flow and the powder, the powder is prevented from being carried out of the auxiliary shell 104 when the saw blade 103 continues to rotate, so that the clearance between the tail of the auxiliary shell 104 and the saw blade 103 is smaller, the air flow and the powder cut by the auxiliary shell 104 enter the filter cloth bag 201 along the dust collecting tube 108, and the dust in the filter cloth bag 201 can be filtered by the material of the filter cloth bag 201, and the dust in the filter cloth bag 201 can be filtered by the filter cloth bag 201, and the dust can leave the filter cloth 201 and the filter device when the dust is discharged outside the filter cloth 106, and the filter cloth is used for the environment is reduced.
While when the saw blade 103 continuously works, dust in the filter cloth bag 201 is continuously increased, when dust in the filter cloth bag 201 continuously plugs an air outlet hole in the filter cloth bag 201, the pressure in the filter cloth bag 201 is synchronously increased, a pressure detection device 218 is activated after the pressure in the filter cloth bag 201 reaches a preset value, a winch motor 205 is started at the moment, the winch motor 205 drives a winch 203 to rotate, the winch 203 drives a scraping sheet 215 to move towards a base plate 204 through a steel cable 219, in the moving process of the scraping sheet 215, the powder which plugs an inner hole of the filter cloth bag 201 in the filter cloth bag 201 is cleaned out through a brush, in the moving process of the scraping sheet 215, a scraping spring 216 is continuously compressed, the scraping spring 216 stores energy to prepare for the scraping sheet 215 to return to an initial position, at the moment, after the scraping sheet 215 moves to the preset position, the main column teeth 214 are contacted with the main column teeth 214, then the scraping sheet 215 presses the main column teeth 214 in the moving process, so that the main column teeth 214 drive the auxiliary column teeth 212 to move towards the dust collecting tube 108 through the first gear 213, at the moment, the auxiliary column teeth 212 are contacted with the sliding rail blocks 208 and press the sliding rail blocks 208, the aim is to enable the sliding rail blocks 208 to drive one end of the filter cloth bag 201 out of contact with the base plate 204 through the cloth bag sliding rail 207, the scraping sheet 215 drives powder cleaned at one end of the filter cloth bag 201 out of the filter cloth bag 201 and is accumulated in the collecting shell 106, a water spraying module in the base plate 204 can be arranged in advance before the powder is driven out of the filter cloth bag 201, if the water is used for cutting materials such as wood, stone and the like which can reduce dust, the powder separated from one end of the filter cloth bag 201 can be subjected to wetting treatment through the water spraying module on the base plate 204, therefore, the powder can be prevented from falling randomly in the subsequent work, and if the material which is easy to be stuck after being dipped with water is not used, the water spraying module in the base plate 204 is not started, and it is worth to be explained here that the filter cloth bag 201 is separated from the base plate 204 in the working process, but the separation gap between the filter cloth bag 201 and the base plate 204 is very small due to the limitation of the movement distance of the auxiliary column teeth 212, and the collection shell 106 is arranged outside the filter cloth bag 201 to block, so that the device cannot achieve the effect of protecting the working environment.
After the cutting of the device is completed, the auxiliary shell 104 rotates around the axis of the saw blade 103 like the protection auxiliary shell in the prior art, as shown in fig. 2, so as to complete the effect of the device for completely wrapping the saw blade, the auxiliary shell 104 is separated from the dust collecting pipe 108 while the auxiliary shell 104 rotates around the axis of the saw blade 103, meanwhile, the auxiliary shell 104 drives the inclined gear 301 to rotate through the annular rack, the inclined gear 301 drives the blocking plate switch 306 to move towards the direction close to the filter cloth bag 201 through the gearbox 304 and the third gear 305, so that the blocking plate 308 moves, and then the channel between the dust collecting pipe 108 and the filter cloth bag 201 is blocked, powder in the filter cloth bag 201 does not run out of the device through the dust collecting pipe 108, then the inclined gear 301 drives the cloth rod 206 to rotate through the second gear 302 and the transmission belt 303, so that the cloth rod 206 drives the contact block 209 to move towards the direction close to the blocking plate 308, and the slide rail block 208 drives one end of the filter cloth bag 201 to move towards the direction close to the filter cloth bag 201, so that the filter cloth bag 201 is rubbed off by the filter cloth 201, and then the filter cloth 201 is completely rubbed off by the filter cloth 201, and the filter cloth 201 is simultaneously, so that the filter cloth 201 is completely pulled out of the filter cloth 201 is simultaneously when the filter cloth 201 is scratched down, and the filter cloth 201 is simultaneously, and the filter cloth 201 is completely moves down, and the filter cloth 201 is simultaneously in the filter bag 201 is completely in the state.
