[0024] The present utility model provides a hemmer for knitted garment hems, which includes a fixed base 101, a connecting arm, a hemmer body 102 and an adjusting mechanism. The adjusting mechanism includes a rotating assembly, a servo motor 103, a threaded rod 104 and a ball screw nut pair 105. The connecting arm includes a mounting base 106, a rotating disk 107, a connecting plate 108, a sleeve column 109 and a sliding column 110. The rotating assembly includes a driving motor 111 and an output gear 112. By the foregoing solution, the problem that in the actual use process of the existing hemmer for knitted garment hems, the user needs to manually adjust the position of the hemmer body 102, the degree of automation is relatively low, and the operation is not convenient enough is solved. It can be understood that the foregoing solution can be used in the structure of the hemmer for knitted garment hems.

[0025] For this specific embodiment, the fixed base 101 is installed on the operating table of the sewing machine by bolts. The upper surface of the fixed base 101 is provided with the connecting arm, and the end of the connecting arm extending outside the fixed base 101 is provided with the hemmer body 102. The hem of the garment is inserted into the hem cavity formed by the main body part, the curling part and the hemming part of the hemmer body 102. Here, the hemmer body 102 is an existing public technology, so it will not be elaborated. Thus, the hem of the garment is folded in half after passing through the hem cavity of the hemmer body 102 to produce a hem, and finally the folded hem of the garment is sewn by a sewing machine, thereby completing the processing of hemming the hem of the knitted garment.

[0026] Among them, the mounting base 106 is fixedly installed on the upper surface of the fixed base 101. A rotating disk 107 is rotatably arranged on the upper surface of the mounting base 106. A rotating assembly is arranged inside the mounting base 106. The output end of the rotating assembly is mechanically transmitted to the rotating disk 107. One end of the connecting plate 108 is fixedly connected to the upper surface of the rotating disk 107. The other end of the connecting plate 108 is fixedly provided with a sleeve column 109. The sleeve column 109 is perpendicular to the connecting plate 108. A sliding column 110 is slidably arranged at one end of the sleeve column 109 away from the connecting plate 108.

The output gear 112 meshes with the driven tooth part 113. Start the driving motor 111 to drive the output gear 112 to rotate. Since the output gear 112 meshes with the driven tooth part 113, the rotating disk 107 is driven to rotate on the mounting base 106.

[0028] At the same time, a limiting block 114 is arranged at one end of the threaded rod 104 away from the servo motor 103. The limiting block 114 is located inside the sleeve column 109. Through the setting of the limiting block 114, the ball screw nut pair 105 is prevented from falling off the threaded rod 104.

[0029] In addition, a fixing ring 115 is provided at one end of the mounting base 106 close to the fixed base 101. The fixing ring 115 is detachably connected to the upper surface of the fixed base 101. The fixing ring 115 is fixed to the upper surface of the fixed base 101 by screws, thereby completing the installation of the mounting base 106.

[0030] When using the hemming device for the lower hem of a knitted garment of this embodiment, the lower hem of the garment is inserted into the hemming cavity formed by the main body portion, the curling portion, and the hemming portion of the hemming device body 102, so that the lower hem of the garment is folded in half after passing through the hemming cavity of the hemming device body 102 to produce a hem. Finally, the folded lower hem of the garment is sewn by a sewing machine, thereby completing the processing of hemming the lower hem of the knitted garment. And when adjusting the position of the hemming device body 102, the rotating assembly is started to drive the rotating disk 107 to rotate on the mounting base 106, so as to adjust the position of the hemming device body 102 through the cooperation of the connecting arm, the sleeve column 109, and the sliding column 110. And the servo motor 103 is started to drive the threaded rod 104 to rotate. Since the ball screw nut pair 105 is connected to the inner bottom wall of the sliding column 110, the sliding column 110 slides inside the sleeve column 109, further completing the adjustment of the position of the hemming device body 102. With the above structure, through the setting of the adjusting mechanism, the position of the hemming device body 102 can be automatically adjusted, and the operation is more convenient.
