Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, and in particular to a spunlace nonwoven fabric production device with a cleaning structure. Background Technology

[0002] Spunlace nonwoven fabric is produced by spraying high-pressure micro-jet water onto one or more layers of fiber web, causing the fibers to entangle and thus strengthening the web to a certain strength. The resulting fabric is called spunlace nonwoven fabric. Its fiber raw materials are widely available, including polyester, nylon, polypropylene, viscose fiber, chitosan fiber, microfiber, Tencel, silk, bamboo fiber, wood pulp fiber, seaweed fiber, etc. Currently, existing spunlace nonwoven fabric production equipment uses spunlace technology and requires winding the fabric. During winding, lint, loose threads, and other debris remain on the upper and lower surfaces of the fabric, requiring cleaning.

[0003] Patent CN220907981U discloses a spunlace nonwoven fabric production device with a cleaning structure, including a support frame, a support plate fixedly connected to the front side of the support frame, a suction mechanism above the support frame, and a sweeping mechanism above the support frame; the suction mechanism includes a collecting part and a suction part, the collecting part being located above the support plate and the suction part being located above the support frame; the sweeping mechanism includes a moving part and a sweeping part, the moving part being located above the support frame and the sweeping part being located below the moving part.

[0004] The aforementioned patent still has the following technical defects: the brush is a fixed structure, which has limited cleaning ability, and lint is easy to accumulate on the brush. Excessive lint accumulation will cause the brush to fail, and the lint accumulated on its surface will also fall onto the non-woven fabric. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a spunlace nonwoven fabric production device with a cleaning structure.

[0006] The technical solution of this utility model is a spunlace nonwoven fabric production device with a cleaning structure, comprising:

[0007] The machine base has a frame at its bottom and a mounting bracket on the machine base.

[0008] Two sets of cleaning roller assemblies are arranged side by side on the mounting frame. Each cleaning roller assembly includes a rotating shaft, a rotating cylinder, and bristles. The rotating shaft is rotatably mounted on the mounting frame, the rotating cylinder is movably located on the outside of the rotating shaft, and the rotating cylinder is slidably connected to the rotating shaft along the length of the rotating shaft. The bristles are mounted on the outer periphery of the rotating cylinder.

[0009] A power assembly mounted on a mounting bracket to drive two rotating shafts to rotate in opposite directions;

[0010] A reciprocating motion mechanism for realizing the back-and-forth movement of a rotating cylinder includes a spring, a ring, and a movable rod. The spring and the movable rod are respectively located on both sides of the rotating cylinder. The spring is sleeved on the rotating shaft, and the movable rod is connected to the rotating cylinder. A ball bearing is installed at the end of the movable rod. The ring is located on the mounting frame near one end of the movable rod. A wave groove structure is provided on one side of the ring near the movable rod, and the wave groove structure surrounds the ring.

[0011] A vacuuming mechanism used to clean the two bristle surfaces.

[0012] Preferably, both sides of the machine tool are provided with screws, and two threaded rings are threadedly connected to each screw.

[0013] Preferably, the vacuuming mechanism includes a vacuum cleaner and two vacuum heads, both of which are mounted on a mounting frame. The vacuum cleaner is mounted on a machine base, and a vacuum hose is connected between the input end of the vacuum cleaner and both vacuum heads.

[0014] Preferably, the power assembly includes a servo motor and two gears, which are respectively mounted on the ends of two rotating shafts and are meshed together. The servo motor is mounted on a mounting bracket and its output shaft is connected to the rotating shaft.

[0022] Example 1

[0023] like Figures 1-4 As shown in the figure, the spunlace nonwoven fabric production device with a cleaning structure proposed in this embodiment includes a machine base 1, a power component, a dust collection mechanism, a reciprocating motion mechanism, and two sets of cleaning roller assemblies.

[0024] A frame 2 is provided at the bottom of the machine base 1, and a mounting frame 3 is provided on the machine base 1. Two sets of cleaning roller assemblies are arranged side by side on the mounting frame 3. The cleaning roller assembly includes a rotating shaft 11, a rotating cylinder 4, and bristles 5. The rotating shaft 11 is rotatably mounted on the mounting frame 3. The rotating cylinder 4 is movably located on the outside of the rotating shaft 11 and is slidably connected to the rotating shaft 11 along its length direction. A key 14 is provided on the rotating shaft 11 along its length direction. A keyway that matches the key 14 is provided on the inner side of the rotating cylinder 4. The bristles 5 are installed on the outer periphery of the rotating cylinder 4 and are evenly and densely distributed on the surface of the rotating cylinder 4.

[0025] A power assembly is mounted on the mounting bracket 3 to drive two rotating shafts 11 to rotate in opposite directions. The power assembly includes a servo motor 9 and two gears 10, which are respectively mounted on the ends of the two rotating shafts 11 and are meshed together. The servo motor 9 is mounted on the mounting bracket 3 and its output shaft is connected to the rotating shaft 11. Limiting rings 12 are rotatably mounted on the ends of the rotating cylinders 4 on both sides. A connecting rod 19 connects the two limiting rings 12. An annular groove is formed on the rotating cylinder 4, and the limiting rings 12 are rotatably positioned inside the annular groove. The connecting rod 19 is used to fix the two limiting rings 12 together, thereby allowing the two rotating cylinders to rotate in opposite directions. 4. It can move synchronously; the reciprocating motion mechanism is used to realize the back-and-forth movement of the rotating cylinder 4. The reciprocating motion mechanism includes a spring 13, a ring 15 and a movable rod 16. The spring 13 and the movable rod 16 are respectively located on both sides of the rotating cylinder 4. The spring 13 is sleeved on the rotating shaft 11. The two ends of the spring 13 abut against the end of the rotating cylinder 4 and the gear 10 respectively. The movable rod 16 is connected to the rotating cylinder 4. A ball bearing 17 is installed at the end of the movable rod 16. The ring 15 is located on the mounting frame 3 near one end of the movable rod 16. A wave groove structure is provided on one side of the ring 15 near the movable rod 16. The wave groove structure surrounds the ring 15.

[0026] The vacuuming mechanism is used to clean the surfaces of the two brush bristles 5. The vacuuming mechanism includes a vacuum cleaner 6 and two vacuum heads 18. Both vacuum heads 18 are mounted on the mounting frame 3. It should be noted that the two vacuum heads 18 are located above and below the non-woven fabric, respectively. The bottom vacuum head 18 is used to absorb debris from the bottom surface of the non-woven fabric and the bottom brush bristles 5, while the top vacuum head 18 is used to absorb debris from the top surface of the non-woven fabric and the top brush bristles 5. However, the installation method of the two vacuum heads 18 is not limited to this. The vacuum cleaner 6 is mounted on the machine base 1, and a suction pipe is connected between the input end of the vacuum cleaner 6 and the two vacuum heads 18. Furthermore, a cloth bag should be connected to the output end of the vacuum cleaner 6 for collecting debris.

[0027] Specifically, the two ends of the spunlace nonwoven fabric are connected to a take-up roller and an unwind roller, respectively, so that the nonwoven fabric passes between two sets of cleaning roller assemblies. At the same time as the nonwoven fabric is being wound up, the servo motor 9 is started to drive the two gears 10 to rotate. The gears 10 in turn drive the cleaning roller assembly to rotate. Through the rotational friction of the two bristles 5, the lint and debris on both sides of the nonwoven fabric can be cleaned. In addition, the bristles 5 generate static electricity during the rotational friction, making it easier for the surface of the bristles 5 to attract lint. At the same time, as the rotating cylinder 4 rotates, it drives the movable rod 16 to rotate. The ball 17 at the end of the movable rod 16 rolls on the surface of the ring 15. Since the surface of the ring 15 is provided with a wave groove undulation structure, the rotating cylinder 4 can move back and forth along the length direction of the rotating shaft 11 during the rotation, thereby further improving the cleaning ability of the cleaning roller assembly. The dust suction mechanism can attract the lint on the surface of the two bristles 5 to ensure the continuous dust removal work of the cleaning roller assembly.

[0028] Example 2

[0029] like Figure 1 As shown in the figure, the spunlace nonwoven fabric production device with a cleaning structure proposed in this embodiment has the following advantages over the first embodiment: both sides of the machine base 1 are provided with screws 7, and two threaded rings 8 are threadedly connected to both screws 7. The two threaded rings 8 can limit the nonwoven fabric and prevent the nonwoven fabric from shifting in position during the winding process. Furthermore, the threaded rings 8 are threadedly connected to the screws 7, which allows the threaded rings 8 to adjust their position on the screws 7. This makes it suitable for limiting the position of nonwoven fabrics of different sizes, and it has strong applicability.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
