Description

Driving device of yarn guide in braid knitting machine {Driving apparatus of yarn guide in braid knitting machine}

The present invention is a follow-up application of the Utility Model Registration Application No. 2000-26619 of the present applicant, more specifically, to improve the structure of the drive device for rotating the left and right between the real guides to reduce the noise and vibration generated during driving, It is possible to improve productivity by enabling high-speed rotation between thread guides, and also relates to a drive device between thread guides of a string knitting machine that can be operated smoothly.

In general, the fabrics used as strings have been woven with looms, but in this case, the machines are large and complex, which takes up a lot of installation space and makes a lot of noise during operation. There was a problem that the productivity was low because the number was reduced.

Recently, a knitted fabric manufacturing apparatus which twists and twists a plurality of strands in a zigzag shape while repeatedly rotating a plurality of circular needles arranged up and down while simultaneously rotating the circular guides left and right (Domestic Patent Publication 1998) -71), but in this case, the thread guide rod that rotates from side to side with the apostle is operated by the pinion gear and the rack gear. Therefore, when rotating at high speed, noise is severe, gaps are generated, and accuracy is reduced. In addition, when the crank is changed from rotary to reciprocating for the up and down movement, the crank is made of metal, so the weight is heavy and the noise and vibration are severe. There was a problem of being inefficient and unproductive because it could not be installed.

On the other hand, in order to solve such a problem, the Korean Utility Model Publication No. 1994-8522 connects a belt with many holes to the crank to reciprocate the left and right between the thread guide and the thread guide, and the lever and the needle needle fixed to the shaft connected to the crank By connecting the pedestal with rods, the needle and the base stand can be moved up and down, eliminating noise during work, and by installing multiple time gears with a perforated belt, multiple levers can be installed on one shaft to improve productivity. A knitted paper knitting apparatus for making a string has been proposed.

However, since the knitted fabric knitting device for string production repeatedly rotates the thread guides left and right by driving the belt with one crank, this also has a problem in that noise and vibration are severely generated during driving, and structurally, the high speed rotation Difficult to have a problem of low productivity.

The object of the present invention is to solve the above-mentioned drawbacks, and to improve the structure of the driving device to rotate the thread guide left and right repeatedly to reduce the noise and vibration generated during driving, The present invention provides a driving device between the thread guides of a string knitting machine to enable high speed rotation to improve productivity and to operate smoothly.

In order to achieve the above object, the present invention installs the operation plate at the rear of the thread guide cylinders so as to pivotally support the center of the operation plate, and fixes both ends of the timing belt at both ends of the operation plate. Motor driving rollers are installed on both rear sides of the operation plate, respectively, and one end of the cranks, each of which is a two-section link, is connected to both rear sides of the operation plate, and the other ends of the cranks are eccentrically opposed to the driving rollers. Each is connected.
