Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of textile accessories, in particular to an automatically calibrated rear beam bracket. Background Art
[0002] The air jet loom is a shuttleless loom that uses jet airflow to pull the weft yarn through the shed. It has the advantages of wide variety adaptability, low machine material consumption, high efficiency, high speed and low noise. It has become one of the most promising new looms.
[0003] However, in the process of changing fabric types and adjusting the process parameters of the air jet loom to adapt to the loom, the position of the rear beam of the air jet loom has a significant impact on the weaving efficiency. It is inevitable to adjust the front and rear position of the rear beam to obtain a good fabric style and a higher loom efficiency. The existing air jet loom usually sets a group of rear beam brackets on both sides of the frame, and uses cylinders to drive the rear beam brackets to slide left and right on the air jet loom frame to adjust the front and rear position of the rear beam. However, due to the error formed by the driving cylinders on both sides, it is difficult to ensure that the positions of the rear beam brackets on both sides remain completely consistent and aligned, and the position difference of the rear beam brackets will cause the beam rollers connected to the rear beam bracket brackets on both sides to tilt, resulting in unstable tension of the rear beam, which will affect the tension of the warp yarn and further affect the quality and style of the fabric.
