Description
Technical Field
[0001] The utility model relates to the technical field of textile machinery, in particular to a yarn tension control device which can be opened and closed freely. Background Art
[0002] At present, there are two main ways for textile yarn winders to control the tension of yarn production. One is the rotating tension disk method, such as the winding machine models produced by Italy, Germany and Qingdao Hongda Textile Machinery in China. This method uses an active motor to drive the tension disk to rotate, and adopts pneumatic or electromagnetic pressurization. The structure is complex, the volume is large, and the cost is high; the other is grid tension control, such as Japan's Murata winder. The rotating tension disk structure requires a separate rotating motor to drive. During the rotation and pressurization process of the tension disk, the upper and lower tension plates are unevenly fitted, resulting in unstable pressure on the yarn, which is easy to cause yarn shaking and ultimately affect the formation of the bobbin. At the same time, due to the rotation of the mechanism, it is easy to cause the phenomenon of entanglement, and an anti-entanglement device needs to be set. Grid tension can effectively solve the above problems, but due to the large number of contact points of grid tension, it is easy to increase the hairiness of the yarn and affect the quality of the yarn. Utility Model Content
[0003] The technical problem solved by the utility model is to provide a device for automatically controlling the tension of yarn which can be opened and closed freely, and an independent device for controlling the tension of yarn which can be used to adjust the tension of yarn by a pneumatic bowl, which is convenient for application in various textile machines which need automatic tension control.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a yarn tension control device, including a cylinder mounting seat and a pneumatic bowl assembly mounting seat; a pneumatic bowl cylinder is installed on a side of the cylinder mounting seat away from the pneumatic bowl assembly mounting seat, and the driving end of the pneumatic bowl cylinder is connected to a guide rod, and the tension bowl assembly is sleeved on the guide rod; the pneumatic bowl assembly includes a pneumatic bowl, a pneumatic bowl dust cover and a spring, and the pneumatic bowl dust cover is fixed to the pneumatic bowl assembly mounting seat by screws, and the axis of the pneumatic bowl and the axis of the guide rod are collinear.
[0005] Furthermore, the tension bowl assembly includes a tension bowl dust cover and a tension bowl. A bearing is installed on the axis of the tension bowl. A sleeve used in conjunction with the bearing is installed on the axis of the tension bowl dust cover to ensure that the tension bowl can rotate. The tension bowl and the guide rod are both made of industrial 99-type alumina ceramics with a smooth and wear-resistant surface, ensuring that the yarn produces minimal hairiness during high-speed operation.
[0006] Furthermore, the length of the guide rod is 1.2-2 times of the thickness of the tension bowl, so as to ensure that when the driving end of the pneumatic bowl cylinder is extended, there is a gap between the pneumatic bowl and the tension bowl.
[0007] Furthermore, the pneumatic bowl assembly mounting seat and the pneumatic bowl dust cover are correspondingly provided with spring holes.
[0008] Furthermore, it also includes an adjustment mounting seat, which is installed on a side away from the cylinder mounting seat, and an adjustment component is installed on the adjustment mounting seat.
[0009] Furthermore, the adjustment component includes a bolt connected to the adjustment mounting seat, the bolt is connected with a spring positioning nut for adjusting the spring limit, and the tension of the tension bowl is adjusted by the spring positioning nut.
[0010] Furthermore, the axes of the bolt, the spring hole and the guide rod are collinear.
[0011] The beneficial effects of the utility model are as follows: the utility model realizes the free opening and closing of the yarn grip by setting the control of the electromagnetic valve cylinder, which is convenient for the automatic control of the yarn entering and exiting the tension bowl, and at the same time adjusts the tension of the pneumatic bowl on the yarn by adjusting the position of the spring. For different yarns, the force of the spring on the pneumatic bowl is adjusted by adjusting the position of the spring positioning nut on the bolt, thereby realizing the tension of the pneumatic bowl on the yarn. At the same time, by setting the coordinated use of the bearing and the shaft sleeve, when the yarn contacts the surface of the tension bowl during movement, the tension bowl can be rotated by using the eccentric pulling force of the yarn without increasing the rotation of the motor, and will not cause wear to the yarn, thereby ensuring the quality of the yarn.

DETAILED DESCRIPTION
[0018] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.
[0019] like Figures 1 to 5 The yarn tension control device shown in the figure, which can be opened and closed freely, comprises a cylinder mounting seat 11 and a pneumatic bowl assembly mounting seat 21; a cylinder hole is provided on the cylinder mounting seat 11, and a pneumatic bowl cylinder 141 is installed on the side of the cylinder mounting seat 11 away from the pneumatic bowl assembly mounting seat 21 by screws, and a guide rod 142 is connected to the driving end of the pneumatic bowl cylinder 141; a tension bowl assembly is sleeved on the guide rod 142. The cylinder mounting seat 11 and the pneumatic bowl assembly mounting seat 21 are respectively fixed on the fixed plate by screws; the pneumatic bowl assembly comprises a pneumatic bowl 23, a pneumatic bowl dust cover 22 and a spring 34, the pneumatic bowl dust cover 22 is fixed on the pneumatic bowl 23 assembly mounting seat 21 by screws, and the spring 34 is placed inside the pneumatic bowl 23, and has elastic force on the pneumatic bowl 23, so that the pneumatic bowl 23 moves toward the tension bowl assembly direction; the pneumatic bowl dust cover 22 can prevent the yarn from entering the gap between the pneumatic bowl 23 and the pneumatic bowl assembly mounting seat 21. The axis of the pneumatic bowl 23 and the axis of the guide rod 142 are colinear. When the yarn is wound and no pressure is needed on the yarn, the driving end of the pneumatic bowl cylinder 141 extends to push the pneumatic bowl 23 away from the tension bowl assembly, so that there is a gap between the tension bowl 12 assembly and the pneumatic bowl 23. When pressure needs to be added to the yarn, the spring 34 pushes the pneumatic bowl 23 to apply tension to the yarn. To ensure safety, a cylinder protective cover is installed on the pneumatic bowl cylinder 141.
[0020] On the basis of the above, if Figures 1 to 4 As shown, the tension bowl assembly includes a tension bowl dust cover 13 and a tension bowl 12. A bearing 152 is installed on the axis of the tension bowl 12. The axis of the tension bowl dust cover 13 is installed with a sleeve 151 used in conjunction with the bearing 152 to ensure that the tension bowl 12 can rotate. During operation, when the yarn contacts the surface of the tension bowl 12, the surface of the tension bowl 12 can rotate, reducing wear on the yarn and ensuring the quality of the yarn. In this embodiment, the tension bowl 23, the pneumatic bowl 23 and the guide rod are all made of industrial 99 type alumina ceramics, with a smooth and wear-resistant surface, ensuring that the yarn produces minimal hairiness during high-speed operation.
[0021] On the basis of the above, if Figure 3 and Figure 5 As shown, in order to ensure that the pneumatic bowl cylinder 141 can create a gap between the surface of the pneumatic bowl 23 and the tension bowl 12 when driving the cylinder bowl, and that the pneumatic bowl 23 will not deviate when not driven, the guide rod 142 plays a guiding role. The length of the guide rod 142 ranges from 1.2 to 2 times the thickness of the tension bowl 12. In this embodiment, 1.6 times the thickness of the tension bowl 12 is selected.
[0022] On the basis of the above, if Figure 2 and Figure 3 As shown, in order to adjust the tension of the pneumatic bowl 23 on the yarn, the pneumatic bowl assembly mounting seat 21 and the pneumatic bowl dust cover 22 are provided with spring holes. An adjustment mounting seat 31 is mounted on the fixed plate, and the adjustment mounting seat 31 is mounted on a side away from the cylinder mounting seat 11, and an adjustment assembly is mounted on the adjustment mounting seat 31.
[0023] On the basis of the above, if Figure 2 and Figure 3 As shown, the adjustment component includes a bolt 32 connected to the adjustment mounting seat 31. In order to prevent the bolt 32 from loosening, the bolt 32 is fixed to the adjustment mounting seat 31 by a nut; a spring positioning nut 33 for limiting the position of an adjustment spring 34 is connected to the bolt 32, one end of the spring 34 is limited by the spring positioning nut 33, and the other end of the spring 34 is in contact with the pneumatic bowl 23. The tension of the tension bowl 12 is adjusted by the spring positioning nut 33. When the pneumatic bowl 23 needs to exert a greater tension on the yarn, the spring positioning nut 33 is moved toward the pneumatic bowl 23. When the pneumatic bowl 23 needs to exert a smaller tension on the yarn, the spring positioning nut 33 is moved away from the pneumatic bowl 23, so that the pneumatic bowl 23 can provide different tensions for different yarns and adapt to various yarn usage scenarios.
[0024] On the basis of the above, if Figure 3 As shown, the axes of the bolt 32, the spring 34 hole, the pneumatic bowl 23, the tension bowl 12, and the guide rod 142 are collinear, ensuring that the pneumatic bowl 23 and the tension bowl 12 provide uniform tension to the yarn. In order to facilitate the temporary fixing of the yarn when the spindle is replaced, as shown in FIG. Figures 1 to 3 As shown, a yarn hanging hook is also provided on the dust cover of the tension bowl.
[0025] The above specific embodiments further illustrate the purpose, technical solutions and beneficial effects of the present invention in detail. It should be understood that the above are only specific embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
