An anti-tangle wire drawing machine

Abstract

The invention discloses a wire drawing machine capable of preventing wire winding, and belongs to the field of plastic processing machinery. The wire drawing machine comprises a machine frame, rollers, a transmission shaft and a first motor, wherein the rollers are distributed on the machine frame in a staggered mode, and an output shaft of the first motor is connected with the rollers through a torque limiter; the interiors of the rollers are hollow, knife rests and cutting blades are further arranged inside the rolls, springs are arranged on the knife rests, the cutting blades are connectedto the knife rests through the springs, and second motors are further arranged on the knife rests; and limiting sleeves are further arranged between the knife rests and the rolls, and the limiting sleeves are connected with the knife rests through the second motors. Overload protection can be carried out on the motors through the torque limiter on the wire drawing machine, and when the motors areoverloaded, the torque limiter can send out signals to enable the first motor to stop, meanwhile, the torque limiter enables the second motor to drive the limiting sleeves to rotate, so that the cutting blades extend out of the rollers to cut off plastic wire. According to the scheme, the problem that the wire winds the rollers is solved, and meanwhile, the situation that the first motor is damaged due to that the first motor is overloaded is avoided.

Description

technical field [0001] The invention relates to the field of plastic processing, in particular to an anti-wrap wire drawing machine. Background technique [0002] The process of plastic woven bag production line is generally: PP, PE material or recycled material → drying mixer → wire drawing machine → winding machine → circular loom → bag cutting machine → sewing machine → printing machine → PP woven bag → packing machine. The wire drawing machine includes a frame, a traction roller, a drawing roller and a first motor. The traction roller and the stretching roller are on the frame, and the traction roller and the stretching roller are driven to rotate by the first motor to realize the stretching of the plastic filament. [0003] However, in the process of plastic stretching, the plastic filaments are entwined between the rollers, and the rollers will be wrapped around the filaments. The plastic filaments are tightly wound on the rollers, which is not easy to clean. When th...
