Technical Field

The invention relates to a conveying device, in particular to an elastic yarn conveying device with small elastic error.

Background

At present, common elastic yarns are rolled into a cylinder for storage, and in such a storage mode, the elasticity of the outer layer of elastic yarn can gradually compress the inner layer of elastic yarn, so that the needed tension force when the elastic yarn is pulled down from a winding drum can be different; when the socks are woven, the elastic yarns are clamped through the driving idler wheel and the driven idler wheel, and are pulled down from the winding drum at a certain pulling force and woven into the socks; the driving roller is connected with a stepping motor, and the length of the elastic yarn knitted into the socks is accurately controlled through the stepping motor; however, as the weaving speed of the existing hosiery machine is gradually increased, the rotating speed of the stepping motor needs to be correspondingly increased, but when the rotating speed of the stepping motor is too high, the control precision is reduced, and the defective rate of papermaking is increased; meanwhile, with the use of the elastic yarn on the winding drum, under the condition that the clamping tension of the driving roller and the driven roller is not changed, the length of the elastic yarn woven into the socks can be changed, and the elastic error of the elastic yarn during conveying is larger, so that the elastic error displayed by the finished socks is larger; socks manufactured after a period of time are defective, so that the waste of raw materials is greatly increased, and the production cost is increased; the socks that current knitwear and hosiery factory can arrange extra personnel to weaving carry out regularly random access inspection, has increased the cost of labor input, and random access inspection operation can not in time discover, also can lead to the higher problem of defective percentage. Therefore, the existing elastic yarn conveying device has the problems of low control precision, large elastic error during conveying of elastic yarns and high defective rate of finished socks.

Disclosure of Invention

The invention aims to provide an elastic yarn conveying device with small elasticity error. The invention not only can improve the control precision, but also has the advantages of smaller elastic error and lower defective rate of finished socks when the elastic yarn is conveyed.

The technical scheme of the invention is as follows: an elastic yarn conveying device with small elastic error comprises a fixed seat, wherein a stepping motor is connected to the fixed seat; a large gear disc is fixedly connected to the stepping motor, and a small gear disc is arranged on one side of the large gear disc in a meshed mode; a turntable is concentrically fixed on the pinion disc, and the diameter of the turntable is larger than that of the pinion disc; one side of the rotary table is provided with a conveying disc in a clinging manner, and the conveying disc is rotatably connected to the fixed seat; and a tensioner is arranged on one side of the fixed seat corresponding to the conveying disc.

In the elastic yarn conveying device with a small elastic error, the number of teeth of the large gear disc is 2.5-4 times that of the small gear disc.

In the elastic yarn conveying device with a small elastic error, the number of teeth of the large gear disc is 3.5 times that of the small gear disc.

In the elastic yarn conveying device with small elastic error, the tensioner comprises a connecting rod fixed on the fixed seat, and a yarn passing hole is formed in one end part, close to the fixed seat, of the connecting rod; two compression discs are sleeved on the connecting rod, a knob is connected to one end portion, far away from the fixing seat, of the connecting rod in a threaded mode, and a spring is connected between the knob and the compression discs.

In the elastic yarn conveying device with small elastic error, the pressure between the two pressing discs is 60-260 kpa.

In the elastic yarn conveying device with small elastic error, the pressure between the two pressing disks is 160 kpa.

In the elastic yarn conveying device with a small elastic error, a second conduit is connected to the position, corresponding to the position between the tensioner and the conveying disc, on the fixed seat.

In the elastic yarn conveying device with a small elastic error, a first conduit is fixed on the fixing seat corresponding to the tensioner at a position on one side of the tensioner far away from the conveying disc.

In the elastic yarn conveying device with a small elastic error, a third conduit is fixed on the fixed seat corresponding to the position of one side of the conveying disc far away from the tensioner.

Compared with the prior art, the invention improves the prior elastic yarn conveying device, the large gear disc is fixed on the stepping motor, the small gear disc is arranged on the large gear disc in a meshed manner, the rotary disc with the diameter larger than that of the small gear disc is concentrically fixed on the small gear disc, the elastic yarn is tightly pressed and conveyed by the rotary disc and the conveying disc in a clinging manner, and the stepping motor can improve the conveying speed of the elastic yarn under the condition of lower rotating speed and ensure the control precision; a tensioner is arranged on one side of the conveying disc, the elastic yarn is compressed through the tensioner and pulled by the rotary disc and the conveying disc, so that the elastic yarn can be conveyed after being stretched as much as possible (so as to dilute the elastic error on the elastic yarn and reduce the elastic error during conveying of the elastic yarn), and then the elastic yarn is knitted into the socks after being reset; in the conveying mode, the error of pulling the inner layer elastic yarn and the outer layer elastic yarn of the winding drum is diluted by the pressing force of the tensioner, the lengths of the elastic yarns conveyed by the rotary disc and the conveying disc each time are the same, and the defective rate is low; and too much raw materials for knitting socks can not be wasted, repeated and frequent random inspection is not needed, and the production cost is lower. In addition, the gear ratio of the large gear disc to the small gear disc is 3.5:1, so that the stepping motor can drive the elastic yarn to be conveyed quickly at a slow rotating speed, and the requirement of a high-speed hosiery machine is met; the elastic yarn is conveyed after passing through the yarn passing hole, the elastic yarn is pressed by the two smooth pressing disks, the pressing force between the two pressing disks is controlled by the elastic force of the spring, and different pressures can be adjusted according to different elastic yarns; after multiple tests and tests, the pressure between the pressing discs is 60-260 kpa, so that various common elastic yarns can be stretched to the maximum stretching length and cannot be broken; a first wire guide pipe, a tensioner, a second wire guide pipe, a conveying disc and a third wire guide pipe are sequentially arranged on the fixing seat, and the first wire guide pipe, the second wire guide pipe and the third wire guide pipe can guide the elastic yarn well and prevent deviation during conveying. Therefore, the invention not only can improve the control precision, but also has the advantages of lower defective rate, lower production cost and wider application range.
