Description

Technical Field

[0001] The utility model relates to the textile field, in particular to a cloth unwinding mechanism. Background Art

[0002] When processing the cloth, the winding mechanism pulls the raw cloth from the cloth roll into the processing equipment for processing, and the processed finished product will be wound on the winding roller.

[0003] Usually, the unwinding roller of the raw cloth is directly placed on the groove of the support frame. When the winding mechanism pulls the raw cloth to drive the winding roller to rotate, a large friction is generated between the winding roller and the support frame, which hinders the transportation of the cloth. At the same time, the winding roller moves left and right when rotating, causing the cloth to shift, thereby affecting the processing of the cloth. Utility Model Content

[0007] By adopting the above technical solution, the unwinding roller rolled with the raw cloth is placed on the two rotating shafts of the mounting seat, and the winding roller is located between the limit rods. When the winding mechanism pulls the unwinding roller to rotate, the unwinding roller belt will drive the two rotating shafts to rotate, thereby reducing the friction between the winding roller and the mounting seat; the two sides of the unwinding roller are restricted by the limit rods and will not move left and right. At the same time, the rotation of the unwinding roller will also drive the two rotating wheels on the limit rods to rotate, thereby reducing the friction between the unwinding roller and the limit rod, and better conveying the cloth.

[0009] With the above technical solution, the cloth on the unwinding roller passes between the two rollers, and the lead screw drives the two rollers to move up and down, thereby changing the distance between the cloth roll and the rollers and adjusting the tension of the cloth.

[0010] Preferably, a threaded rod is rotatably connected to the support frame.

[0011] With the above technical solution, the cloth passes under the threaded rod, and the movement of the cloth drives the threaded rod to rotate. The threads of the threaded rod smooth out the wrinkles of the cloth to prevent affecting the processing of the cloth.

[0012] Preferably, the support frame is rotatably connected to a rotating rod, a connecting plate is fixedly connected above the rotating rod, and a meter is fixedly connected to the middle of the connecting plate.

[0013] By adopting the above technical solution, the cloth passes between the meter counter and the rotating rod, and the meter counter is used to measure the processed length of the cloth, so that the cloth of the required length can be obtained.

[0014] Preferably, two support seats are fixedly connected to the surface of the mounting seat below the rotating shaft, the support seat is provided with a groove, the rotating shaft is embedded in the groove, the two ends of the rotating shaft are respectively embedded in the grooves of the two support seats, the side walls of the groove are threadedly connected with bolts, the bolt heads are located in the grooves and in contact with the rotating shaft.

[0015] By adopting the above technical solution, the rotating shaft can be fixed and disassembled by tightening the bolts, so that the rotating shaft can be replaced. BRIEF DESCRIPTION OF THE DRAWINGS
