Automatic cord clamping device for steel cord wrapping machine

Abstract

The invention provides an automatic cord clamping device for a steel cord wrapping machine. The automatic cord clamping device for the steel cord wrapping machine comprises a pneumatic cord clamping device arranged between tension guide wheels and a moment arm guide wheel of the wrapping machine, wherein the pneumatic cord clamping device comprises a cylinder, a cylinder shaft, a first polyurethane gasket, a fixing support, a baffle and a second polyurethane gasket; the first polyurethane gasket is arranged on the cylinder shaft; the second polyurethane gasket is arranged on the baffle; the pneumatic cord clamping device and the wrapping machine are fixed through the fixing support; the pneumatic cord clamping device is connected with a solenoid valve through a vent pipe; and the solenoid valve is connected with a PLC module in a machine tool control cabinet of the wrapping machine through a control wire. By the automatic cord clamping device, a cord can be automatically clamped in time when equipment stops, and retraction of the cord is completely eradicated effectively; when running of the equipment recovers, the cord can be released automatically, and normal running of the wrapping machine is guaranteed; and accumulation of external wrapping wires of cords is completely eradicated, negative hidden dangers are avoided, and the quality of products is stabilized.

Description

technical field [0001] The invention relates to the technical field of steel cord production, in particular to an automatic wire clamping device for a steel cord outer winding machine. Background technique [0002] In the current steel cord outer winding process, the I-shaped wheel is used to pay off the wire and the FP lubricant is used for the outer winding. After the machine tool is stopped, the cord cutting needs to be checked. The arm springs back due to the tension, so that the cord wound on the machine tool is retracted by about 5MM as a whole. When driving again, the outer winding wire at the outer winding head of the outer winding spindle will continuously rotate and accumulate at the same point of the cord, giving the product to the product. It will bring serious quality risks; if the outer winding of VSV or ADMU lubricant is used, the retraction of the cord will not be obvious, and the accumulation of the outer winding will not be formed, but the length of the twi...

Problems solved by technology

[0002] In the current steel cord outer winding process, the I-shaped wheel is used to pay off the wire and the FP lubricant is used for the outer winding. After the machine tool is stopped, the cord cutting needs to be inspected. The arm rebounds due to the tension, so that the cord wound on the machine tool will retract about 5mm as a whole. When driving again, the outer winding wire at the outer winding head of the outer winding spindle will continue to rotate and accumulate at the same point of the cord, which will cause damage to the product. Serious hidden dangers in quality; if VSV or ADMU lubricant is used for the outer winding wire, the cord retraction phenomenon is not obvious, and the accumulation of the outer winding wire will not be formed, but the length of the broken wire after twisting the cord will be significantly reduced and the semi-finished product will be increased. quantity

At present, the φ25*5 strong magnetic adsorption device used at the take-up place of the outer winding machine cannot play the role of fixing the cord, and the retraction of the cord cannot be avoided; affect product quality
