Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric winding technology, and in particular to a limiting device for winding automotive nonwoven fabric. Background Technology

[0002] Nonwoven fabric is a type of non-woven material. It is made by directly forming fibers from polymer chips, short fibers, or filaments into a web through airflow or mechanical means, then reinforcing it through hydroentangling, needle punching, or thermal rolling, and finally finishing it to form a non-woven fabric. It is a new type of fiber product with softness, breathability, and a planar structure. Its advantages include no fiber lint, strength, durability, silky softness, and it is also a type of reinforcing material. It also has a cotton-like feel. Compared with cotton fabrics, nonwoven bags are easier to shape and cheaper to produce.

[0003] After production, nonwoven fabrics need to be wound up for storage and transportation. Existing nonwoven fabric winding equipment has a simple structure and lacks a complete winding limit function. During the winding process, serious skewness is prone to occur, resulting in uneven winding of the nonwoven fabric and a decrease in the neatness of the winding. This not only reduces the quality of the nonwoven fabric winding but may also require secondary winding of the uneven nonwoven fabric, thereby reducing the efficiency of nonwoven fabric winding. Moreover, due to the different thicknesses and types of nonwoven fabrics, the tension required during winding is also different. Failure to adjust in time can easily cause patterns to appear on the surface of the nonwoven fabric, affecting product quality. Utility Model Content

[0005] This application provides a limiting device for winding automotive nonwoven fabric, including a worktable; a winding roller and a guide rod are provided on the worktable; mounting brackets are provided on both sides of the winding roller; the guide rod is located in front of the winding roller; connecting supports are provided on both sides of the guide rod; a limiting component is provided on the guide rod; the limiting component includes a limiting ring and an adjusting screw; there are two limiting rings, both of which are slidably sleeved on the guide rod; the limiting rings are symmetrically installed on the guide rod with respect to the center of the guide rod; a connecting block is provided at the bottom of the limiting ring; a transverse connecting hole is provided on the connecting block; an internal thread is provided inside the connecting hole; one internal thread of the connecting hole is right-handed and the other is left-handed; the adjusting screw is located in the two connecting holes and is rotatably connected to the connecting holes; both ends of the adjusting screw are rotatably connected to the connecting supports on both sides; an external thread is provided on the adjusting screw; half of the external thread is right-handed and half is left-handed; the internal thread of the connecting hole corresponds to the external thread of the adjusting screw; an adjustment box is provided at one end of the adjusting screw.

[0006] Preferably, the side end of the take-up roller is connected to the output end of the drive motor; the drive motor is externally mounted in a fixed housing.

[0007] Preferably, the adjustment box is located outside the connecting support; the adjustment box is provided with a rotating gear and an adjusting worm gear.

[0008] Preferably, the rotating gear meshes with the adjusting worm; the adjusting screw passes through the connecting support and is fixedly disposed in the middle of the rotating gear.

[0009] Preferably, the bottom of the connecting support is provided with multiple telescopic rods, which are fixedly connected to the workbench.

[0010] The beneficial effects of this utility model are as follows: According to the width of the nonwoven fabric to be wound, the adjusting worm gear inside the control box can be manually rotated to allow the two limiting rings to slide on the guide rod until the distance between the two limiting rings is equivalent to the width of the nonwoven fabric. Simultaneously, the self-locking function of the worm gear fixes the two limiting rings. During the winding process, this effectively limits the movement of the nonwoven fabric, preventing it from skewing during winding and ensuring the quality of the nonwoven fabric winding. Furthermore, the connecting supports on both sides of the guide rod can be continuously height-adjusted to maintain good surface tension during winding, thereby improving production quality.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] like Figures 1 to 2The illustrated limiting device for winding automotive nonwoven fabric includes a worktable 1; the worktable 1 is provided with a winding roller 2 and a guide rod 3; mounting brackets 21 are provided on both sides of the winding roller 2; the guide rod 3 is located in front of the winding roller 2; connecting supports 4 are provided on both sides of the guide rod 3; a limiting component is provided on the guide rod 3; the limiting component includes limiting rings 6 and adjusting screws 5; there are two limiting rings 6, both of which are slidably sleeved on the guide rod 3; the limiting rings 6 are symmetrically installed on the guide rod 3 about the center of the guide rod 3; a connecting screw is provided at the bottom of the limiting rings 6. Connecting block 61; the connecting block 61 is provided with a transverse connecting hole 611; the inner side of the connecting hole 611 is provided with an internal thread; one of the internal threads of the connecting hole 611 is right-handed and the other is left-handed; the adjusting screw 5 is located in the two connecting holes and is rotatably connected to the connecting hole 611; both ends of the adjusting screw 5 are rotatably connected to the connecting supports 4 on both sides; the adjusting screw 5 is provided with an external thread; half of the external thread is right-handed and half is left-handed; the internal thread of the connecting hole 611 corresponds to the external thread of the adjusting screw 5; one end of the adjusting screw 5 is provided with an adjusting box 8. The principle is similar to that of a bidirectional lead screw, which is a left-hand and right-hand lead screw. Half of the thread on the screw thread is left-handed and half is right-handed. When the screw rotates in one direction, the two nuts on the thread separate or come together. When it rotates in the opposite direction, the two nuts come together or separate. By adjusting the rotation of the lead screw 5, the connecting block 611 is moved, so that the limiting ring 6 gathers or separates on the guide rod 3. Non-woven fabrics of different widths pass through the two limiting rings 6, which can limit the non-woven fabrics of different widths.

[0017] The side end of the take-up roller 2 is connected to the output end of the drive motor 23; the drive motor 23 is externally mounted with a fixed housing, and the motor controls the rotation of the take-up roller 2 to take up the non-woven fabric.

[0018] The adjustment box 8 is located on the outside of the connecting support 4; the adjustment box 8 is provided with a rotating gear 81 and an adjusting worm 82.

[0019] The rotating gear 81 meshes with the adjusting worm 82. The regulating screw 5 passes through the support 4 and is fixedly installed in the middle of the rotating gear 81. By rotating the adjusting worm 82, the rotating gear 81 is rotated, which in turn causes the regulating screw 5 connected to it to rotate synchronously, thereby achieving the purpose of controlling the movement of the limit ring 6.

[0020] The bottom of the connecting support 4 is provided with multiple telescopic rods 7, which are fixedly connected to the workbench 1. The telescopic rods 7 can adjust the height of the connecting support 4 and control the surface tension of the nonwoven fabric.

[0021] This device allows the two limiting rings to slide on the guide rod 3 by manually rotating the adjusting worm gear 82 inside the control box 8 until the distance between the two limiting rings 6 is equivalent to the width of the nonwoven fabric. At the same time, the self-locking function of the worm gear is used to fix the two limiting rings 6, thereby achieving the limiting function of the nonwoven fabric.

[0022] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
