Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of textile equipment and relates to a pin wheel structure on a fabric setting machine. Background Art
[0002] The upper needle wheel device is widely used in the textile printing and dyeing industry. It is a key device for the setting machine to control the needle effect of the cloth edge. Due to the diversity of the fabric structure and subsequent processing flow of the produced fabrics, different fabrics have precise requirements for the pressing tightness of the upper needle wheel. Due to the defects of the single mechanical screw adjustment that cannot be measured and recorded, improper operation will cause cloth surface quality problems such as white marks and wood ear edges. Through the needle wheel pressure adjustment, the standard pressure values of different fabrics can be accurately controlled, thereby controlling abnormal factors and improving quality control. At present, the mounting seat of the needle wheel is installed on the frame through the locking bolt. The position of the needle wheel is adjusted by rotating the mounting seat and locking it through the locking bolt, thereby adjusting the pressure between it and the fabric. However, this method not only has no buffer to cope with the fluctuation of fabric tension, resulting in poor quality stability under fabric tension fluctuations, but also this method is prone to slight changes in position during the force application of the needle wheel, thereby causing the adjusted pressure to gradually decrease during the operation, and there is also a problem of poor stability. Utility Model Content
[0003] The purpose of the utility model is to provide a pin wheel structure on a fabric setting machine in view of the above problems existing in the prior art. The technical problem to be solved by the utility model is how to make the pin wheel pressure have a certain buffer during the change of fabric tension.
[0004] The purpose of the utility model can be achieved through the following technical solutions: a needle wheel structure on a fabric setting machine, characterized in that it includes a mounting seat, two swing arms, a needle wheel body and a control arm, the mounting seat is rotatably connected to a main shaft, one end of the two swing arms is rotatably connected to the two sides of the needle wheel body, the other end of the swing arm is rotatably connected to the main shaft through a bearing, the middle part of the control arm is fixedly connected to the main shaft, a permanent magnetic column is fixedly provided at the front end of the control arm, the rear end of the control arm is connected to a push rod of a cylinder, and an iron adsorption column adapted to the permanent magnetic column is provided on the swing arm.
[0005] Furthermore, the iron adsorption column is rotatably connected to the swing arm through a thread, and there is a gap between the iron adsorption column and the permanent magnet column.
[0006] The iron adsorption column can be screwed in or out to adjust the adsorption force between it and the permanent magnetic column, thereby adjusting the flexibility of the needle wheel.
[0007] Furthermore, a limit rod is fixedly provided at the front end of the control arm, and the limit rod is located below the swing arm; when the permanent magnetic column is parallel to the iron adsorption column, there is a distance between the limit rod and the swing arm.
[0008] This solution uses a contactless magnetic force to control the position of the needle wheel body, achieving buffering while extending the distance between the needle wheel body and the control arm, so that safe operation can be performed without stopping the machine; the swing of the control arm is controlled by a cylinder, and the swing of the control arm can drive the main shaft to rotate. Under the action of magnetic force, the swing arm can be controlled to swing. When the needle wheel is unevenly stressed, the contactless magnetic force can achieve buffering within a certain range to avoid mutual damage between the needle wheel and the fabric; the limit rod can support the needle wheel when the pressure of the needle wheel fluctuates greatly or fails, so as to avoid damage caused by collision between the needle wheel body and the frame.

[0013] The iron adsorption column 7 is connected to the swing arm 2 by screw thread rotation, and there is a gap between the iron adsorption column 7 and the permanent magnetic column 6. The iron adsorption column 7 is screwed in or out to adjust the adsorption force between it and the permanent magnetic column 6, thereby adjusting the flexibility of the pin wheel.
