detailed description

The invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

As shown in Figures 1 to 8, a sewing hemming machine cloth feeding and hemming device includes an inclined first cloth threading chamber 1, an inclined second cloth threading chamber 2 and an edge wrapping port 3, the first cloth threading chamber The outlet end of chamber 1 is connected to the cloth inlet end of the second cloth threading chamber 2. The chamber body is a flat cavity with a wide cloth inlet end and a narrow cloth outlet end. The middle of the second cloth threading chamber 2 is set to be concave forward. Concave arc-shaped cavity 4, with curling arc-shaped cavity 5 on both sides, the cloth outlet end is connected with the edge wrapping port 3, the cloth inlet end is wide, and the cloth outlet end is narrow, after the cloth is discharged, both sides of the edge wrapping cloth are curled , the edge-wrapping mouth 3 is a U-shaped mouth that is inclined backward, and the curled cloth at the outlet end of the second cloth threading chamber 2 is pulled backward through the U-shaped mouth to automatically wrap the edge. The arc-shaped cavity 5 is connected, and the concave arc-shaped cavity will position the middle of the hemming cloth. As the hemming cloth enters the width gradually changes to the second cloth-threading cavity, the curved arcs on both sides will automatically move the two sides of the hemming cloth. Crimp until the outlet gets the proper hemming width.

Preferably, the cloth inlet end of the first cloth threading chamber 1 is provided with a tensioning mechanism 6, the tensioning mechanism 6 is a serpentine steel wire 7 bent multiple times, and one end of the serpentine steel wire 7 is rotatably connected to On the back of the first cloth threading chamber 1, the serpentine steel wire can tighten and straighten the hemming cloth first, which is convenient for subsequent hemming stretching and symmetrical curling, which greatly improves the hemming effect and prevents the hemming cloth from entering the first The piercing cavity is asymmetrical and curved.

Preferably, the front wall of the first cloth piercing chamber 1 is provided with a strip-shaped opening-8, through which a rod is used to push the hemming cloth, so that the hemming cloth can be sent out of the first cloth-piercing chamber conveniently, reducing the amount of hemming cloth The feeding preparation time is shortened, which greatly improves the production efficiency.

Preferably, an adjustment opening 9 is provided at the joint between the first cloth threading chamber 1 and the second cloth threading chamber 2, and the hemming cloth can be adjusted symmetrically by adjusting the opening before the first cloth threading chamber of the hemming cloth is curled and hemmed. , the operation is convenient and quick, and there is a free end 10 extending from the front wall of the second cloth piercing cavity 2 on the front side of the adjustment opening 9, and the free end 10 is warped forward to allow the edge cloth to pass through the adjustment opening smoothly, thereby Avoid the hemming cloth arching here, causing the hemming cloth to get stuck, thus causing damage to the equipment.

Preferably, the front wall of the second cloth piercing chamber 2 is provided with a strip-shaped opening 2 11, and a rod is used to push the hemming cloth through the strip-shaped opening 2, so that the hemming cloth can be sent out of the second cloth-piercing chamber conveniently, reducing the amount of hemming cloth The feeding preparation time is shortened, which greatly improves the production efficiency.
