Technical Field

[0001] The present application relates to the technical field of fabric napping equipment, and in particular to a napping equipment for regenerated silk fabric. Background Art

[0002] Recycled silk fabric is a fabric woven from yarn formed by crushing, cleaning, mixing and drying qualified waste materials and then melt-extruded. After the fabric processing is completed, the surface of the fabric will be napped to make the fabric feel more comfortable. The napping treatment is usually carried out directly using a napping machine.

[0003] The patent with application number CN202020620940.1 discloses a new type of roughening machine, including a machine body and a workbench arranged on the machine body, two roughening frames are symmetrically and fixedly connected on the workbench, and a roughening device is arranged between the two roughening frames. The roughening device includes a first roughening roller and a second roughening roller rotatably connected to the roughening frame, and the roughening frame is provided with a slide rail for the second roughening roller to slide. Both ends of the first roughening roller and the second roughening roller are fixedly connected with a rotating shaft, and the roughening frame is provided with a through hole for the rotating shaft to rotate, and the first roughening roller is arranged directly below the second roughening roller.

[0004] When the napping roller of the napping machine processes the surface of the fabric, the napping roller will pull out part of the limit on the surface of the fabric and tear it off, and the broken limit will adhere to the napping roller. When the napping roller processes fabrics of different colors, the fiber filaments adhered to the napping roller will adhere to the surface of the fabric being processed, thereby causing the surface of the fabric being processed to produce debris, thereby affecting the quality of the fabric.

[0005] Therefore, it is necessary to propose a new technical solution to solve the above problems. Utility Model Content

[0008] A napping device for regenerated silk fabrics, comprising a frame, an extrusion roller rotatably connected to the frame, a napping roller rotatably connected to the frame, a plurality of napping layers circumferentially arranged on the outer wall of the napping roller, and a napping driving member for driving the napping roller to rotate, wherein the extrusion roller and the napping roller are arranged vertically, and the frame is also provided with a hair removal component for driving the fibers to detach from the napping layer, the hair removal component comprises a fixed rod fixed to the frame and a blowing member for driving the fibers to move, the fixed rod is hollow and has a blowing hole connected to an inner cavity of the fixed rod on its outer wall, the air outlet of the blowing member is connected to the inner cavity of the fixed rod, the napping roller is coaxially sleeved on the fixed rod and rotates along the fixed rod, the outer wall of the napping roller is penetrated by a plurality of air outlet grooves, and the air outlet grooves are connected to the blowing hole.

[0009] By adopting the above technical solution, when the napped layer pulls out and hooks off the fibers, causing the fibers to adhere to the napped layer, the hair removal component blows air to the fibers on the napped layer, thereby separating the fibers from the napped layer. When the napped layer continues to nap the fabric, the fibers that were previously hooked off will not adhere to the fabric again.

[0012] Optionally: the blowing hole is arranged at the upper end of the fixing rod, and the inner wall of the napping roller is in contact with the inner wall of the blowing hole.

[0013] By adopting the above technical solution, when the napped layer rotates to the upper end, it is blown so that the fibers are detached from the napped layer, and the detached fibers move upward and are sucked by the dust collection component, making it easier to collect the fibers.

[0017] By adopting the above technical solution, the nozzle is used to further exert a force on the fiber to move away from the nap layer, so that the fiber is separated from the nap layer.

[0018] Optionally: a baffle is fixed to the lower end of the dust hood, the baffle is arranged on the side of the napping roller away from the squeezing roller, and the baffle is arranged on the side of the axis of the napping roller close to the fabric conveying.

The air guide holes are arranged along the axis of the napping roller, and one end of the air guide hole away from the axis of the napping roller is inclined toward the closest napping layer.

[0021] By adopting the above technical solution, the air guide hole is used to guide the flow direction of the air flow blown out from the air outlet groove, so that the air flow is blown toward the end of the nap layer away from the fixed rod, making it easier for the fibers to detach from the nap layer.

[0022] Optionally: a filter screen is also provided in the air outlet groove, and the filter screen is provided on a side of the guide block close to the axis of the napping roller.

DETAILED DESCRIPTION

[0031] The present application is further described in detail below in conjunction with the accompanying drawings.

[0032] The present application discloses a napping device for regenerated silk fabrics, such as Figure 1 and Figure 2 As shown, it includes a frame 1, an extrusion roller 11 rotatably connected to the frame 1, a napping roller 12 rotatably connected to the frame 1, a plurality of napping layers 13 circumferentially arranged on the outer wall of the napping roller 12, and a napping driving member 14 for driving the napping roller 12 to rotate. The napping roller 12 is arranged above the extrusion roller 11, and the fabric passes between the extrusion roller 11 and the napping roller 12. The frame 1 is also provided with a hair removal component 2 for removing fibers on the napping layer 13. The hair removal component 2 includes a fixed rod 21 fixed to the frame 1 and a blowing member 22 for inflating air into the fixed rod 21. The fixed rod 21 is hollow, and a blowing hole 211 communicating with its inner cavity is opened on its upper end surface. The blowing hole 211 is arranged parallel to the axis of the fixed rod 21. In this embodiment, the blowing member 22 is a hair dryer, and the air outlet of the blowing member 22 is communicated with the fixed rod 21. The nap roller 12 is coaxially rotatably connected to the outside of the fixed rod 21, and the inner cavity of the nap roller 12 is also hollow. A plurality of air outlet grooves 121 communicating with the inner cavity are provided on the outer wall of the nap roller 12, and the air outlet grooves 121 are arranged between adjacent nap layers 13. A plurality of seals 15 are also fixed to the inside of the nap roller 12 by bolts, and the seals 15 are arranged between adjacent air outlet grooves 121. In this embodiment, the seals 15 are made of engineering plastics, and the two ends of the seals 15 are respectively abutted against the inner cavity ends of the nap roller 12, and the end of the seals 15 close to the fixed rod 21 is kept in abutment and slides against the outer wall of the fixed rod 21. In this embodiment, the napping drive member 14 is a motor, and the free end of the napping drive member 14 is connected to the end of the napping roller 12 through a belt, thereby driving the napping roller 12 to rotate. After the air outlet groove 121 is connected to the blowing hole 211, the air flows toward the end of the napping layer 13 away from the fixed rod 21, so that the limit is blown away from the end of the napping layer 13.

[0033] like Figure 1As shown, since the blown-away fibers will also float in the environment, a dust collecting assembly 3 for sucking the blown-off limiter is also provided on the frame 1. The dust collecting assembly 3 includes a dust collecting hood 31 fixed on the frame 1 and a bag dust collector 32 for sucking air. The dust collecting hood 31 is provided with a lower opening. The dust collecting hood 31 is provided above the napping roller 12 and the opening of the dust collecting hood 31 faces the napping roller 12. The bag dust collector 32 is provided on the ground, and the air inlet of the bag dust collector 32 is connected to the upper end of the dust collecting hood 31 and communicated with the inner cavity of the dust collecting hood 31, so that after the limiter is blown off from the napping layer 13, the dust collecting assembly 3 can suck and collect the fibers, so that the blown-off fibers will not fall directly into the processing environment.

[0034] like Figure 3 As shown, in order to better make the air flow toward the position of the napped layer 13 away from the fixed rod 21, a guide block 16 is fixed to the air outlet groove 121 by bolts to close it, and two rows of guide holes 161 are opened on the guide block 16 along its length direction. The guide holes 161 are away from each other at one end away from the fixed rod 21, so that the air blown out of the guide holes 161 flows toward the end of the napped layer 13 away from the fixed rod 21, so that the flowing air can better blow away the fibers attached to the napped layer 13.

[0035] In order to prevent debris from falling into the inner cavity of the fixed rod 21 when the machine is stopped, a filter 17 is provided in the air outlet groove 121. The filter 17 closes the opening of the air outlet groove 121 close to the inner cavity of the fixed rod 21, and the filter 17 abuts against the side wall of the guide block 16 close to the fixed rod 21. The filter 17 is used to filter debris, so that the debris will not directly enter the inner cavity of the fixed rod 21 and affect the flow of air.

[0036] like Figure 1 As shown, in order to make it easier to blow away the fibers on the nap layer 13, the frame 1 is also provided with a plurality of nozzles 18 for blowing air to the nap layer 13. The nozzles 18 are arranged along the axis of the nap roller 12, and the nozzles 18 are arranged on the side of the nap roller 12 away from the fabric conveying direction. The air inlet of the nozzle 18 is connected with the air outlet of the blowing member 22, and the air outlet of the nozzle 18 is inclined toward the top of the nap roller 12, so that the extension line of the air outlet of the nozzle 18 can intersect with the highest end of the nap layer 13, so that the nozzle 18 is used to assist in applying an upward force to the fibers, so that the limiter is separated from the nap layer 13.

[0037] In order to ensure that the blown-off fibers can still be sucked by the dust hood 31 when the fibers are subjected to the force applied by the nozzle 18, a baffle 33 is fixed at the lower end of the dust hood 31 to guide the flow direction of the air. The baffle 33 is arranged on the side of the napping roller 12 close to the fabric input, and the lower end of the baffle 33 is lower than the upper end of the napping roller 12. After the air moves toward the baffle 33, it moves upward under the guidance of the baffle 33, so that the air mixed with the fibers can be more easily sucked by the dust hood 31.

[0038] The implementation principle of this embodiment is: when the fabric passes between the squeezing roller 11 and the napping roller 12, the napping roller 12 rotates in the same direction as the squeezing roller 11, and the napping layer 13 naps the surface of the fabric. During the rotation of the napping roller 12, the air outlet groove 121 is connected with the blowing hole 211 so that the flowing air is blown toward the end of the napping layer 13 away from the fixed rod 21, so that the limit is blown off the napping layer 13, and the nozzle 18 also blows air toward the napping layer 13 to assist in blowing the fibers upward, and then the blown-off fibers are sucked by the dust hood 31.

[0039] The embodiments of this specific implementation method are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
