Description

Technical Field

[0001] The utility model relates to the technical field of warping machines, in particular to a yarn tension stabilizing structure of a warping machine. Background Art

[0002] The warping machine is a device that winds the yarn evenly onto the warp beam with a certain tension according to the number and length required by the weaving process.

[0003] The working principle of a commonly used warping machine is as follows: yarn or filament is drawn from a bobbin on a creel, collected by a collecting plate, and evenly wound onto a warp beam via a reed, tension rollers, static eliminator, oiler, yarn storage device, expansion reed, and yarn guide rollers. The creel is equipped with ancillary devices such as a tensioning device, a yarn breakage stop device, a static eliminator, and a signal light.

[0004] Although the yarn tension is adjusted by the tension device when the yarn is drawn out from the creel, the tension of the yarn will fluctuate after being transported. When the yarn is evenly wound onto the warp beam by the yarn guide roller, the tension consistency of each yarn is generally poor, which affects the subsequent weaving quality. Therefore, there is an urgent need for a device that can further stabilize the yarn tension and make it consistent. Utility Model Content

[0005] In order to solve the above technical deficiencies, the utility model provides a yarn tension stabilizing structure for a warping machine, which further stabilizes the yarn tension and makes the tension of each yarn more consistent.

[0006] The utility model discloses a yarn tension stabilizing structure for a warping machine, comprising a frame, a warp beam being arranged on the frame, a base being arranged on the frame at the side where the warp beam comes in, a cavity being arranged inside the base, vertical guide holes being arranged at even intervals along the axial direction of the warp beam on the upper side of the base, the inner diameters of the guide holes being equal and the guide holes being connected to the cavity, guide posts being slidingly arranged in the guide holes, seals being arranged on the guide posts, the seals being pressed against the inner walls of the guide holes, the upper ends of the guide posts being located outside the guide holes and a No. 1 yarn guide ring being arranged on the upper ends, a fixing rod being arranged on the base at equal distances from the incoming and feeding sides of each No. 1 yarn guide ring, a No. 2 yarn guide ring being arranged on the fixing rod, a No. 1 mounting hole being arranged on the base which is connected to the cavity, an air pipe being arranged on the No. 1 mounting hole, a control valve being arranged on the air pipe, and the air pipe being connected to an air pump.

[0007] When the utility model is in use, each yarn is passed through the No. 1 yarn guide ring and the No. 2 yarn guide ring respectively, and then fixed on the warp beam. During the warping process of the yarn, the control valve is opened, and a negative pressure is formed in the cavity on the base by the vacuum pump. After a certain pressure is reached, the control valve is closed, so that the guide column moves downward, and the No. 1 yarn guide ring pulls the yarn. Since the inner diameters of the guide holes are all equal, the pulling force of the No. 1 yarn guide ring is equal, so that the yarn is stabilized at a certain tension value. When the tension fluctuation of a certain yarn becomes smaller, the No. 1 yarn guide ring pulls downward more to increase its tension. When the tension fluctuation of a certain yarn becomes larger, the No. 1 yarn guide ring pulls downward less to reduce its tension, thereby stabilizing the tension of the yarn and making its tension consistency good.

[0008] In order to better observe the pressure value in the cavity, a No. 2 mounting hole connected to the cavity is provided on the base, and a pressure gauge is installed on the No. 2 mounting hole.

[0009] The utility model provides a yarn tension stabilizing structure for a warping machine, which has the beneficial effect of pulling the yarn through the No. 1 yarn guide ring, and the pulling force of the No. 1 yarn guide ring is equal, so that the yarn is stabilized at a certain tension value. When the yarn tension fluctuates, the yarn tension is regulated in real time to stabilize the yarn tension and make the tension consistency good. BRIEF DESCRIPTION OF THE DRAWINGS

A fixing rod 6 is provided on the base 3 at equal distances on the incoming and feeding sides of each No. 1 yarn guide ring 10. A No. 2 yarn guide ring 5 is provided on the fixing rod 6. A No. 1 mounting hole communicating with the cavity 12 is provided on the base 3, an air pipe 7 is provided on the No. 1 mounting hole, a control valve 8 is provided on the air pipe 7, and the air pipe 7 is connected to the vacuum pump. A No. 2 mounting hole communicating with the cavity 12 is provided on the base 3, and a pressure gauge 4 is installed on the No. 2 mounting hole.

[0019] When the utility model is in use, each yarn is passed through the No. 1 yarn guide ring 10 and the No. 2 yarn guide ring 5 respectively, and then fixed on the warp beam 2. During the warping process of the yarn, the control valve 8 is opened, and a negative pressure is formed in the cavity 12 on the base 3 by the vacuum pump. After a certain pressure is reached, the control valve 8 is closed, so that the guide column 9 moves downward, and the No. 1 yarn guide ring 10 pulls the yarn. Since the inner diameters of the guide holes 11 are equal, the pulling force of the No. 1 yarn guide ring 10 is equal, so that the yarn is stabilized at a certain tension value. When the tension fluctuation of a certain yarn becomes smaller, the No. 1 yarn guide ring 10 pulls downward more to increase its tension. When the tension fluctuation of a certain yarn becomes larger, the No. 1 yarn guide ring 10 pulls downward less to reduce its tension, thereby stabilizing the tension of the yarn and making its tension consistency good.
