A double meter counting device for an inner take-up twisting machine

Abstract

The invention discloses a double-metering device of an inside take-up wire standing machine. A rotary connecting rod (1) is arranged on the upper portion of the double-metering device, an upper support (2) and a lower support (3) are arranged at the bottom of one side of the rotary connecting rod (1), the upper support (2) is connected with the rotary connecting rod (2) and connected with the lower support (3) by a fixing bolt (4), a photoelectric switch support (5) is disposed on the other side of the rotary connecting rod (1), a photoelectric switch (6) is mounted in the photoelectric switch support (5), a reflector (8) is connected to the bottom of the photoelectric switch (6) by a shield cable (7), and a traction wheel (9) is arranged at the bottom of the reflector (8). After infrared rays of the photoelectric switch (6) irradiate on the reflector (8) during synchronous running of the reflector (8) and the traction wheel (9), an infrared signal is instantly reflected to the photoelectric switch (6) by the reflector (8), and the photoelectric switch (6) instantly meters once and transmits a signal to a display panel after receiving the feedback signal; and a meter signal is not generated when the reflector (8) is not positioned within the infrared range of the photoelectric switch (6).

Description

technical field [0001] The invention provides a double meter counting device for an inner take-up twisting machine. Background technique [0002] According to the requirements of the tire manufacturer for the length of the wire, the length of each round of steel cord must be strictly controlled during the production process of steel cord twisting. In the prior art, the stranding machine tool usually adopts the spindle meter meter device, and uses the proximity switch to count the spindle. Whenever the flywheel of the spindle rotates a circle, the proximity switch counts the number of turns once, and the display panel program automatically multiplies the spindle The circumference of the circle is obtained to obtain the length of one revolution of the main shaft flywheel disc. Therefore, the required total length of the steel cord is preset on the display panel of the stranding machine tool, and each round of take-up I-shaped wheel reaches a fixed length (the rated total leng...

AI Technical Summary

Problems solved by technology

The deficiencies in the prior art are: 1. the twisting machine tool has only one set of meter counting device, and when the proximity switch is damaged or other spare parts that affect the meter meter of the main shaft are damaged, the steel cord actual detection fixed length and the predetermined fixed length appear very different large error, and cannot provide timely information on the meter deviation

2. This stranding machine adopts the inner take-up method. It is relatively simple to install a second meter meter device on the outer pay-off traction wheel and other parts, but there is a large meter error; if the meter is installed on the take-up traction wheel The rice device is quite difficult

Because, when the machine tool is working, the cord rotates at a high speed on the flywheel disc, enclosing the entire cradle in the steel cord, forming a large sealed ellipsoid, and all the take-up parts are inside the ellipsoid, generally close to The switch cannot directly touch the receiving part, so it cannot form a meter
