Description

Weaving zero adjusting device for hosiery machine

Technical Field

The utility model relates to a hosiery machine equipment, especially hosiery machine are with weaving adjusting device at zero point.

Background

At present, a large gear for controlling the height of a needle cylinder is arranged in an existing sock knitting machine, and the rotation of the large gear is controlled by inputting a sock knitting program into a controller, so that socks are knitted; after each sock weaving is finished, the large gear can reset to the position of the sock just beginning to be woven, namely the weaving zero point; the existing hosiery knitter generally fixes a proximity switch at the position of weaving zero point to transmit a signal of finishing the reset of a large gear to a controller so as to continuously weave the same type of socks; however, as the hosiery knitter weaves, the diameter of the yarn on the yarn bobbin is gradually reduced, the tension when the yarn passes through the hole is changed, and the elasticity of the knitted socks is changed under the condition that the weaving zero point of each sock is not changed, so that the quality of the socks is affected, the finished socks are different in length and cannot meet the technological requirements of customers; therefore, in the existing sock knitting factory, one patrol personnel is arranged to be responsible for patrol of a plurality of sock knitting machines, socks woven on the sock knitting machines are detected, if defective socks are found, the sock knitting machines are stopped, and the sock knitting machines are disassembled to adjust the weaving zero points in the socks knitting machines, so that the operation is troublesome; and the stoppage reduces the working efficiency of the hosiery knitting machine. Therefore, the prior art has the problems of troublesome operation and greatly reduced work efficiency of the hosiery knitter.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a loom is with weaving adjusting device at zero point. The utility model discloses the utensil not only can conveniently adjust the operation, still has the advantage that can not reduce hosiery machine work efficiency.

The technical scheme of the utility model: the weaving zero point adjusting device for the hosiery machine comprises a fixed seat fixed with the hosiery machine, wherein a servo motor is fixed on the fixed seat, and a driving device is connected on the servo motor; the fixed seat is provided with a moving piece, and a proximity switch is fixed on the moving piece; the driving device can drive the moving part to move relative to the fixed seat.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given. The weaving zero point adjusting device for the hosiery machine is shown in figures 1 and 2 and comprises a fixed seat 1 fixed with the hosiery machine, wherein a servo motor 2 is fixed on the fixed seat 1, and a driving device is connected on the servo motor 2; the fixed seat 1 is provided with a moving piece, and a proximity switch 5 is fixed on the moving piece; the driving device can drive the moving part to move relative to the fixed seat 1.

The driving device comprises a gear 3 fixed on a rotating shaft of the servo motor 2; the moving piece is an arc-shaped rack 4, and one side of the rack 4 is meshed with the gear 3; position sensors 6 are fixed at two end points of the fixed seat 1 corresponding to the moving path of the rack 4; the other side of the rack 4, which is opposite to the gear 3, is a smooth surface, two ends of the smooth surface of the rack 4 are respectively provided with a rotating wheel 7 fixed on the fixed seat 1, and each rotating wheel 7 is in contact with the smooth surface of the rack 4; a vertical upright post 8 is fixed at the position, opposite to each rotating wheel 7, on the fixed seat 1, and the rotating wheels 7 are rotatably sleeved on the upright posts 8; a sliding groove 9 is formed in the position, right below the rack 4, of the fixed seat 1, a sliding block 10 is slidably clamped in the sliding groove 9, and the top end of the sliding block 10 is fixed with the bottom end of the rack 4; the slider 10 is fixed in the middle of the rack 4.

The working principle is as follows: after the hosiery machine weaves the socks, the working personnel measure the elasticity of the socks and compare the elasticity with the elasticity of the qualified socks, and the servo motor 2 on the fixed seat 1 is controlled to rotate according to the error of the process elasticity, so that the gear 3 on the servo motor 2 rotates and drives the rack 4 to move on the fixed seat 1; a sliding block 10 fixed at the bottom end of the rack 4 slides in a sliding groove 9 on the fixed seat 1, the rotating wheel 7 rotates on the vertical rod 8, and the moving path of the rack 4 is accurately limited under the guiding action of the gear 3 and the rotating wheels 7 at the two end parts of the smooth surface; the proximity switch 5 on the rack 4 also moves synchronously, so that the reset position of a large gear for controlling the height of a needle cylinder on the hosiery machine is adjusted, namely the weaving zero point of the hosiery machine is adjusted; thereby reducing the error of gradual change of the elasticity of the yarn and ensuring the process quality of the socks.

When the gear 3 moves to one end of the rack 4, the position sensor 6 can sense the rack 4 and provide a signal to give an alarm, so that a worker is reminded that the gear 3 is positioned at the two ends of the rack 4, the adjustment of a weaving zero point can not be carried out any more, and manual adjustment is needed; when the staff changes the yarn section of thick bamboo misoperation and changes different elastic yarn section of thick bamboo and get up, the great error of socks elasticity emergence also can lead to 4 direct trigger position sensor 6 of rack to remind the staff to have the yarn section of thick bamboo to have and to change wrong problem, avoid the waste of raw materials.
