[0017] 2. The present invention can also drive the cam to make a circular motion in the process of rotating the placement frame to change the sewing position. After the cam contacts the roller, as the cam continues to move, the roller can be squeezed, and the sliding cooperation between the movable frame and the curling sewing machine can push the movable frame to move together. The movable cooperation between the sleeve rod and the sleeve can drive the stainless steel filter to move. At this time, the spring will be compressed. When the cam is away from the roller, the stainless steel filter will automatically reset due to the rebound effect of the spring itself, thereby achieving the purpose of vibrating the stainless steel filter, and then facilitating the shaking off of debris, wool and fluff attached to its surface to prevent the stainless steel filter from being blocked.

[0018] 3. In the process of the roller being squeezed and moved, the present invention utilizes the sliding cooperation between the slider and the slide rod, and the hinged action between the connecting seat and the strip frame and the connecting rod two, so that the two groups of strip frames can be pushed to move back to each other at the same time, and the hinged action between the strip frame and the connecting rod and the connecting rod one can drive the connecting rod to move outward, and utilizes the movable cooperation between the column rod and the movable groove, and the hinged action between the movable frame and the inner wall of the collection box to drive the knocking ball to deflect. When the stainless steel filter automatically resets, the knocking ball will also automatically reset, so that it can impact the stainless steel filter to generate vibration, thereby improving the effect of removing debris, wool and fluff attached to the stainless steel filter.

[0019] 4. Before knocking the stainless steel filter, the present invention will drive the stainless steel filter and the knocking ball to move simultaneously to maximize the distance between the two. When the two come into contact again, greater collision kinetic energy will be generated to improve the cleaning effect of the stainless steel filter, thereby ensuring the normal filtration of the stainless steel filter.

[0035] The implementation principle of a leather hemming sewing device in the embodiment of the present application is as follows: first, the leather with curled edges is placed on the placement rack 3 and the curled edges are sewn by the curling sewing machine 2. The sewing position can be changed by rotating the placement rack 3. Then, the exhaust fan 105 is started. The air inside the collection box 101 can be extracted by the exhaust fan 105 to form a negative pressure. At this time, the debris, wool and fluff generated during the sewing process can be sucked into the interior of the collection box 101 through the dust cover 103 and filtered through the stainless steel filter 106, thereby achieving the purpose of removing the debris, wool and fluff. In addition, in the process of changing the sewing position by rotating the placement rack 3, the cam 20 can also be driven. 4 makes a circular motion together. When the cam 204 contacts the roller 203, as the cam 204 continues to move, it can squeeze the roller 203, and under the sliding cooperation between the movable frame 202 and the hemming sewing machine 2, it can push the movable frame 202 to move together. The movable cooperation between the sleeve rod 206 and the sleeve 205 can drive the stainless steel filter 106 to move. At this time, the spring 207 will be compressed. When the cam 204 is away from the roller 203, the spring 207 itself rebounds and the stainless steel filter 106 automatically resets, thereby achieving the purpose of vibrating the stainless steel filter 106, thereby facilitating the removal of debris attached to its surface. , wool and fluff are shaken off to prevent the stainless steel filter 106 from being blocked. At the same time, when the roller 203 is squeezed and moved, the sliding cooperation between the slider 217 and the slide bar 218, the hinged action between the connecting seat and the strip frame 213 and the connecting rod 215 are coordinated, so that the two groups of strip frames 213 can be pushed to move back to each other at the same time, and the hinged action between the strip frame 213 and the connecting rod 212 and the connecting rod 1 214 can be used to drive the connecting rod 212 to move outward, and the movable cooperation between the column 211 and the movable groove 210, and the hinged action between the movable frame 208 and the inner wall of the collection box 101 can be used to drive the knocking ball 2 09 is deflected, and when the stainless steel filter 106 automatically resets, the knocking ball 209 will also automatically reset, so that it can hit the stainless steel filter 106 to generate further vibration, thereby improving the removal effect of debris, wool and fluff attached to the stainless steel filter 106. Before knocking the stainless steel filter 106, the stainless steel filter 106 and the knocking ball 209 will be driven to move at the same time to maximize the distance between the two. When the two are in contact again, greater collision kinetic energy will be generated to improve the cleaning effect of the stainless steel filter 106, thereby ensuring the normal filtration of the stainless steel filter 106, and finally the sewn leather goods can be taken away.
