DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. The components of the embodiments of the utility model described and shown in the accompanying drawings herein can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but only represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model protection.

[0025] As shown in Figure 1 Figure 4 The utility model provides a dust cloth quick release device of high speed drawing frame as shown in the figure, including drawing frame body 1, two pay -off racks 2 are fixedly assembled to the bottom inner wall of drawing frame body 1, the pay -off rack 2 can support the fiber strip in roll, then the fiber strip is drawn in high speed by drawing frame body 1, the inner wall of drawing frame body 1 is provided with U-shaped groove 3, the roller 4 is horizontally rotationally connected in drawing frame body 1, the dust cloth 5 of the outer circumferential surface of roller 4 is fixedly assembled and abuts at the inner wall of U-shaped groove 3, the counterweight strip 6 is fixedly assembled to the lower end of dust cloth 5, the counterweight strip 6 is slidingly connected with the inner wall of U-shaped groove 3, when needing to use dust cloth 5, make roller 4 rotate and unfold dust cloth 5, the counterweight strip 6 will drive one end of dust cloth 5 to move downward along the inner wall of U-shaped groove 3 due to gravity, thereby dust cloth 5 seals the exposed part of drawing frame body 1, prevents dust and fly from adhering to the surface of fiber strip, when needing to fold up dust cloth 5, make roller 4 rotate in reverse direction, at this time, dust cloth 5 will be quickly rolled up, thereby the quick folding of dust cloth 5 is completed, avoids the condition that the efficiency is reduced due to slowly removing dust cloth 5, the inner wall of drawing frame body 1 is fixedly assembled and abuts at the surface of dust cloth 5 and is provided with top plate 7, after top plate 7 abuts at the surface of dust cloth 5, can further seal the gap between roller 4 and drawing frame body 1, the outer wall of drawing frame body 1 is fixedly assembled with servo motor 8, the output end of servo motor 8 is fixedly connected with roller 4 coaxially, by setting servo motor 8, when the output end of servo motor 8 rotates, can drive roller 4 to rotate, thereby conveniently control roller 4 to rotate.

[0026] ​In the above scheme, after the dust screen 5 is wound up, the servo motor 8 will be powered off and stop working. At this time, the dust screen 5 is easy to unfold due to the gravity of the counterweight strip 6. In order to avoid the above situation, in this embodiment, the surface of the top plate 7 is fixedly provided with a rectangular plate 9. The rectangular plate 9 is horizontally slidably penetrated by a plug plate 10. The surface of the counterweight strip 6 is provided with a plug slot 11 matched with the plug plate 10. When the plug plate 10 is inserted into the inner wall of the plug slot 11, the plug plate 10 reaches the position of limiting the counterweight strip 6, thereby avoiding the unfolding of the dust screen 5.

[0027] Because the drawing frame body 1 will vibrate during work, the plug plate 10 is easy to slide out of the plug slot 11 and lose the limiting effect. Therefore, it is necessary to prevent the plug plate 10 from sliding out of the plug slot 11 due to vibration. Specifically, the surface of the rectangular plate 9 is fixedly provided with a leaf spring 12. The free end of the leaf spring 12 is fixedly provided on the surface of the plug plate 10. When the leaf spring 12 contracts, the free end of the leaf spring 12 tightly abuts against the inner wall of the plug slot 11.

[0028] Further, in order to prevent the plug plate 10 from blocking the counterweight strip 6 during the upward movement of the counterweight strip 6, the plug plate 10 needs to be pulled away from the dust screen 5 first. The operation process is relatively cumbersome. Therefore, it is necessary to prevent the plug plate 10 from blocking the counterweight strip 6 and reduce the operation complexity. Specifically, the upper surface of the counterweight strip 6 is provided with an inclined surface 13. When the inclined surface 13 of the counterweight strip 6 contacts the plug plate 10, the inclined surface 13 of the counterweight strip 6 will extrude the plug plate 10, so that the plug plate 10 automatically moves away from the dust screen 5, thereby reducing the operation complexity.

[0029] In addition, when the leaf spring 12 contracts, the plug plate 10 is easy to abut against the surface of the dust screen 5 due to overlong movement, which causes the dust screen 5 to deform, thereby affecting the sealing effect of the dust screen 5 on the drawing frame body 1. Specifically, the surface of the plug plate 10 is fixedly provided with a positioning block 14. The positioning block 14 abuts against the surface of the rectangular plate 9. After the positioning block 14 abuts against the surface of the rectangular plate 9, the plug plate 10 cannot continue to move, thereby avoiding the situation that the dust screen 5 is deformed by being abutted by the plug plate 10.

[0030] In order to prevent the edge of the dust screen 5 from not being tightly attached to the inner wall of the U-shaped groove 3, affecting the sealing effect, the edge of the dust screen 5 will be extruded in this embodiment. Specifically, the drawing frame body 1 is fixedly provided with an electric push rod 15. The output end of the electric push rod 15 is fixedly provided with a pressing plate 16. When the output end of the electric push rod 15 extends, the pressing plate 16 will move with the output end of the electric push rod 15. The pressing plate 16 can press the dust screen 5 tightly against the inner wall of the U-shaped groove 3, thereby improving the sealing effect of the dust screen 5.

[0031] During the movement of the pressing plate 16, the pressing plate 16 is prone to deviate and fail to normally extrude the dust cloth 5, and therefore the movement path of the pressing plate 16 needs to be limited, and specifically, a guide rod 17 penetrating through the drawing frame body 1 is fixedly assembled on the surface of the pressing plate 16, and the movement of the pressing plate 16 drives the guide rod 17 to slide along the drawing frame body 1, and the guide rod 17 can limit the movement path of the pressing plate 16.

[0032] In the description of the present application, the terms "first", "second", "another", "yet another" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features limited by "first" and "second" can explicitly or implicitly include one or more features. In the description of the embodiments of the present application, the meaning of "a plurality of" is two or more than two, unless otherwise specifically limited.
