When the blade of the cutting knife 17 contacts the surface of the dust filter bag, the cutting knife 17 starts to cut the dust filter bag until the cutting of the dust filter bag is completed.

[0031] To sum up, the dust filter bag cutting device for bag-type dust removal drives the fixed frame 12 to move to the left or right along the outer side surface of the fixed rod 7 by controlling the sliding block 9. At the same time, the fixed frame 12 indirectly drives the cutting knife 17 to move until it moves to the specified position. Then, the limiting rod 10 is controlled to be inserted into the limiting hole 8 at the specified position to fix it, thereby enabling the staff to adjust the position of the cutting knife 17, facilitating the staff to cut different positions of the dust filter bag according to work requirements, thereby greatly improving the applicability of the device.

[0032] The dust filter bag cutting device for bag-type dust collector uses the contraction force generated by the stretching of the reset spring 11 to continuously pull the limit rod 10 inward, so that the limit rod 10 can move inward along the inside of the sliding block 9 until the limit rod 10 is firmly inserted into the inside of the limit hole 8 at the designated position, thereby improving the fixing effect between the sliding block 9 and the fixing rod 7, indirectly ensuring the stability of the cutting knife 17 when it is in use and preventing shaking.

[0033] The dust removal filter bag cutting device for bag dust removal realizes the function of being movable through the rotatability of four sets of moving wheels 2, which facilitates the staff to move the device to the designated working position, saving time and effort, reducing the labor intensity of the staff, improving the convenience of the device during use, and facilitating the use of the device by the staff.
