Description

Technical Field

[0001] The utility model belongs to the technical field of chemical fiber processing equipment, and more specifically, particularly relates to a wire guide rack for a chemical fiber production line. Background Art

[0002] With the progress of society, the chemical fiber industry has developed greatly, and the demand for chemical fiber products has also increased. Therefore, higher requirements are placed on the production equipment of the chemical fiber industry. In the chemical fiber processing process, the wire guide frame is one of the units in the fiber post-processing combined machine. The wire bundle is formed into a certain width and tension uniformity through the wire guide frame, so the quality of the wire guide frame directly affects the quality of the wire, whether it is its tension, surface smoothness, toughness, etc.

[0003] The existing publication number CN206969888U discloses a wire guide rack for a chemical fiber production line. Although a fixed bracket and a movable bracket are provided, the fixed bracket and the movable bracket are connected by a connecting component, and the distance between the two brackets can be easily adjusted to prevent the silk thread from sagging due to the long distance and the action of gravity, thereby greatly improving the working efficiency of the entire production line. The two bracket columns are retractable.

[0004] Based on the above, the inventors have discovered the following problems: However, after long-term wire guiding, due to the influence of friction and wire gravity, the spacing of the brackets needs to be adjusted again after a period of use, which is time-consuming and labor-intensive and also reduces the work efficiency of the production line. Moreover, when the wires are guided, usually multiple wires are divided into multiple strands for wire guiding, and the wires also have different thicknesses. The device is not suitable for wires of various thicknesses.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a wire guide frame for a chemical fiber production line is provided, in order to achieve a more practical purpose. Utility Model Content

[0026] Example:

[0027] As attached Figure 1 To Attachment Figure 5 As shown:

[0028] The utility model provides a wire guide frame for a chemical fiber production line, comprising a supporting leg 1, a placing box 2 is fixed on the top of the supporting leg 1, fourth connecting rods 14 are fixed at both ends of the bottom of both sides of the placing box 2, a servo motor 15 is fixed on one side of one of the fourth connecting rods 14, a driving gear 16 is fixed on the power output end of the servo motor 15, a driven gear 19 is rotatably connected to one side of the fourth connecting rod 14, a second driven roller 18 is rotatably connected to one side of the other fourth connecting rod 14, a pulley 20 is fixed on one side of the driven gear 19 and one end of the second driven roller 18, a transmission belt 21 is arranged on the outer wall of the pulley 20, a driving roller 17 is fixed on one side of the driving gear 16, third connecting rods 11 are movably installed on the tops of both sides of the placing box 2, and a first driven roller 13 is rotatably connected to the middle of the third connecting rod 11.

[0029] Among them, the two first driven rollers 13 are respectively located in two identical vertical planes with the second driven roller 18 and the active roller 17. A slider 12 is fixed to one end of the third connecting rod 11. The slider 12 is slidably connected to the two ends of the placement box 2, so that the first driven roller 13 is affected by gravity and will automatically fall down. The two first driven rollers 13 are respectively fitted with the top of the second driven roller 18 and the active roller 17, and pressure is applied to the silk thread in the middle through the gravity of the first driven roller 13.

[0030] Among them, the active roller 17 is fixed to the active gear 16 through a rotating shaft, and the rotating shaft runs through the middle of the fourth connecting rod 14. The active gear 16 and the driven gear 19 are meshed with each other. After the silk thread passes through the top of the second driven roller 18, passes through the inside of the placement box 2, and finally passes through the top of the active roller 17, the servo motor 15 is started to rotate clockwise, driving the active roller 17 to rotate clockwise to transport the silk thread. At the same time, the active gear 16 drives the driven gear 19 to rotate counterclockwise, and drives the second driven roller 18 to rotate counterclockwise through the pulley 20 and the transmission belt 21. Since the root circle diameter value of the active gear 16 is smaller than the root circle diameter value of the driven gear 19, the rotation speed of the second driven roller 18 is much smaller than the rotation speed of the active roller 17. The reverse rotation of the second driven roller 18 provides a smaller reaction force to the silk thread when it moves, so that the silk thread remains in a tensioned state.

[0031] Among them, a slide groove 3 is opened on the top of the placement box 2, and a first connecting rod 6 is slidably connected inside the slide groove 3. An extrusion plate 9 is fixed at the bottom of the first connecting rod 6. By moving the first connecting rod 6 inside the slide groove 3, the position of the bottom extrusion plate 9 is driven to change.

[0032] Among them, a support plate 4 is fixed inside the placement box 2, and there are multiple support plates 4 and multiple extrusion plates 9. The multiple support plates 4 and the multiple extrusion plates 9 are arranged in a one-to-one correspondence. One side of the extrusion plate 9 is rotatably connected to the second roller 10, and one side of the support plate 4 is rotatably connected to the first roller 5. By adjusting the position of the first connecting rod 6, the distance between the extrusion plate 9 and the support plate 4 is changed to adapt to the use of fine wires of various thicknesses, and the friction of the silk thread inside is reduced by the first roller 5 and the second roller 10.

[0033] Among them, the second connecting rod 7 is fixed at both ends of the top of the first connecting rod 6, and the two ends of the second connecting rod 7 are fixed with threaded limit bolts 8. After the position of the first connecting rod 6 is adjusted, the position of the second connecting rod 7 is fixed by rotating the limit bolts 8, thereby fixing the position of the first connecting rod 6.

[0034] The specific usage and function of this embodiment are as follows:

[0035] In the present invention, the silk thread is first passed through the top of the second driven roller 18, then through the inside of the placement box 2, and finally through the top of the active roller 17. Then, the position of the first connecting rod 6 is adjusted according to the thickness of the silk thread, and the spacing between the extrusion plate 9 and the support plate 4 is changed to adapt to the use of thin threads of various thicknesses. After the position of the first connecting rod 6 is adjusted, the position of the second connecting rod 7 is fixed by rotating the limit bolt 8, and then the position of the first connecting rod 6 is fixed. The friction of the silk thread inside is reduced by the first roller 5 and the second roller 10, and then the servo motor 15 is started to rotate clockwise, driving the active roller 17 to rotate clockwise to transport the silk thread. At the same time, the driving gear 16 drives the driven gear 19 to rotate counterclockwise, and drives the second driven roller 18 to rotate counterclockwise through the pulley 20 and the transmission belt 21. Since the root circle diameter value of the driving gear 16 is smaller than the root circle diameter value of the driven gear 19, the rotation speed of the second driven roller 18 is much smaller than the rotation speed of the driving roller 17. The first driven roller 13 is affected by gravity and will automatically fall. The two first driven rollers 13 are respectively fitted with the second driven roller 18 and the top of the driving roller 17. The gravity of the first driven roller 13 applies pressure to the silk thread in the middle. The second driven roller 18 rotates in the opposite direction to provide a smaller reaction force to the silk thread when it moves, so that the silk thread remains in a tensioned state.

[0036] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
