Description

Technical Field

[0001] The utility model belongs to the technical field of fabric napping, and in particular relates to a weft knitted fabric napping device. Background Art

[0002] Warp knitting is a textile process belonging to the knitting field. One or several groups of parallel yarns are fed into all the working needles of the machine in the warp direction to form loops at the same time to form a knitted fabric. This method is called warp knitting, and the knitted fabric formed is called warp knitted fabric. The raising machine is also called the raising machine. It is a finishing equipment for the fabric raising process. Raising is to use the raising machine to pull the ends of the fabric fibers out of the yarn so that the surface of the fabric is evenly covered with a layer of fluff.

[0003] When the napping machine pulls the end of the plant fiber out of the yarn and forms fluff, a large number of broken hairs are likely to appear, and the broken hairs are easily adsorbed on the surface of the fabric. In the later work process, the broken hairs are easily floated into the staff's respiratory tract through the mouth and nose as the staff breathes, thereby making the staff's respiratory health easily affected by the presence of broken hairs.

[0033] See also Figures 1-8 As shown, the utility model is a weft-knitted fabric napping device, comprising a napping box 1, a lifting component 2 is provided on the top of the inner wall of the napping box 1, a napping component 3 is provided on the mounting end of the lifting component 2 and the inner wall of the napping box 1, a suction component 4 is provided on the mounting end of the lifting component 2 and the inner wall of the napping box 1, one end of the suction component 4 is fixedly connected to a collecting component 5, both sides of the napping box 1 are fixedly connected to a winding component 6, and a material trough 7 is opened on both sides of the napping box 1.

[0034] The fabric is passed through the interior of the pulling box 1 through the material trough 7, and the cloth tube used to roll up the fabric is put on the two winding components 6. At this time, the pulling ends of the pulling component 3 inside the pulling box 1 are in contact with the upper and lower surfaces of the fabric respectively, and the fabric is also between the suction components 4. With the assistance of the winding component 6, the fabric begins to move inside the pulling box 1, and the two pulling ends of the pulling component 3 pull the moving fabric. After the pulling component 3 passes between the suction components 4, the collecting component 5 can absorb the broken hair on the upper and lower surfaces of the fabric through the suction component 4 and collect the absorbed broken hair.

[0035] By arranging the napping component 3 and the suction component 4 inside the napping box 1, and the fabric can pass through the interior of the napping box 1 through the material trough 7, under the cover of the napping box 1, the broken hairs generated by the napping component 3 when the fabric is napped will not float out from the interior of the napping box 1, and the suction component 4 is arranged on the rear side of the napping component 3, and the interior of the collecting component 5 is in a negative pressure state, so that when the fabric that has completed the napping operation passes between the suction components 4, the collecting component 5 can absorb and clean the broken hairs on the upper and lower surfaces of the fabric and the broken hairs floating inside the napping box 1 through the suction component 4, so that there are no broken hairs on the upper and lower surfaces of the fabric after the fabric moves out of the interior of the napping box 1. The above arrangement ensures that the broken hairs generated when the fabric is napped only exist inside the napping box 1, so that the staff will not develop respiratory diseases due to the presence of broken hairs.

[0037] The hydraulic cylinder 201 can drive the mounting plate 202 to move up and down inside the pulling box 1. At this time, the distance between the two pulling ends of the pulling component 3 and the suction end of the suction component 4 can be adjusted. This setting makes it more convenient to pass the fabric through the inside of the pulling box 1. When the mounting plate 202 moves, it can drive the guide rod 203 to slide on the pulling box 1. The setting of the guide rod 203 ensures the stability of the mounting plate 202 when it moves.

[0038] In one embodiment, for the above-mentioned napping component 3, the napping component 3 includes a mounting frame 301, and the mounting frame 301 is fixedly installed on the bottom of the mounting plate 202.

One side of the support plate 303 is rotatably connected to a lower napping roller 304. One side of the mounting frame 301 is fixedly connected to a support frame 305, and the support frame 305 and the back of the napping box 1 are fixedly installed with a drive motor 306. The output ends of the two drive motors 306 are fixedly connected to the shaft heads of the corresponding upper napping roller 302 and the lower napping roller 304.

[0039] When the fabric passes through the interior of the napping box 1, the upper napping roller 302 moves downward under the drive of the mounting plate 202 and the mounting frame 301 and cooperates with the lower napping roller 304 to contact the upper and lower surfaces of the fabric. When the fabric is napped, the two drive motors 306 drive the corresponding napping rollers to rotate and nap the fabric, so that the upper and lower surfaces of the fabric can be napped. When the height of the upper napping roller 302 is adjusted, the support frame 305 can support the corresponding drive motor 306, so that the direct connection between the drive motor 306 and the shaft head of the upper napping roller 302 will not be affected.

[0040] In one embodiment, for the above-mentioned suction component 4, the suction component 4 includes an upper suction cover 401, the top of the upper suction cover 401 is fixedly connected to the upper suction tube 402, the upper suction tube 402 is fixedly installed on the bottom of the mounting plate 202, and a lower suction cover 403 is provided on the lower side of the upper suction cover 401, and the bottom of the lower suction cover 403 is fixedly connected to the lower suction tube 404, and one end of the lower suction tube 404 is provided with a diversion pipe 405, and one end of the upper suction tube 402 is fixedly connected to the telescopic tube 406, and one end of the telescopic tube 406 is fixedly connected to the diversion pipe 405.

[0041] The mounting plate 202 can adjust the height of the upper suction hood 401 through the upper suction tube 402. During the adjustment, the telescopic tube 406 can be telescoped at the top of the diversion tube 405, so that the upper suction tube 402 can move normally with the mounting plate 202. The setting of the adjustable upper suction hood 401 makes it more convenient for the fabric to pass through between the upper suction hood 401 and the lower suction hood 403. At the same time, the upper suction hood 401 and the lower suction hood 403 can cooperate to absorb the broken hair on the upper and lower surfaces of the fabric, so that the broken hair will not move out of the inside of the pulling box 1 with the fabric.

[0042] In one embodiment, for the above-mentioned wool pulling box 1, an adjustment groove 8 is opened on the inner wall of the wool pulling box 1 corresponding to the support frame 305 and the upper suction tube 402, and the support frame 305 and the upper suction tube 402 are movably connected to the corresponding adjustment groove 8, and the outer surfaces of the support frame 305 and the upper suction tube 402 are fixedly connected with a baffle 9.

[0043] When the mounting plate 202 moves, the support frame 305 and the upper suction tube 402 can slide inside the adjusting groove 8, so that the connection between the upper hair pulling roller 302 and the corresponding drive motor 306 will not be affected, and the connection between the upper suction tube 402 and the diversion tube 405 will not be affected. At the same time, the shielding plate 9 can block the adjusting groove 8, so that the broken hair inside the hair pulling box 1 will not float from the adjusting groove 8 to the outside of the hair pulling box 1.

[0044] In one embodiment, for the above-mentioned collection component 5, the collection component 5 includes a collection box 501, the diversion pipe 405 is fixedly connected to the collection box 501, the collection box 501 is internally movably connected to a collection box 502, an exhaust fan 503 is fixedly installed on the top of the collection box 501, the exhaust end of the exhaust fan 503 is fixedly connected to the collection box 501, a filter screen 504 is obliquely arranged inside the collection box 501, a sealing groove 505 is opened on the front of the collection box 501, and a sealing frame 506 is internally movably connected to the sealing groove 505, and the sealing frame 506 is fixedly connected to the collection box 502.

[0045] The exhaust fan 503 can extract the air flow inside the collection box 501, so that the interior of the collection box 501 is in a negative pressure state. This phenomenon enables the upper suction hood 401 and the lower suction hood 403 to have suction with the assistance of the corresponding suction pipe and the diversion pipe 405, so that the two suction hoods can absorb the broken hair; the diversion pipe 405 connected to the collection box 501 is on the lower side of the filter 504, and the exhaust end of the exhaust fan 503 connected to the collection box 501 is on the upper side of the filter 504. This arrangement ensures that the broken hair extracted will not block the exhaust end, thereby The suction hood can always keep absorbing the broken hair; the broken hair that falls into the collection box 501 can be collected by the collection box 502, so that when cleaning the collected broken hair, the collection box 502 can be directly extracted from the inside of the collection box 501, and the operation is relatively convenient. At the same time, when the collection box 502 is moved to the inside of the collection box 501, the sealing frame 506 can be directly moved to the inside of the sealing groove 505, so that the overall sealing of the collection box 501 can be guaranteed. This setting allows the interior of the collection box 501 to better form a negative pressure state with the assistance of the exhaust fan 503.

[0046] In one embodiment, for the above-mentioned winding component 6, the winding component 6 includes a connecting plate 601, one side of the connecting plate 601 is fixedly connected to the wool pulling box 1, the top of the connecting plate 601 is fixedly connected to a fixed plate 602, the front of the fixed plate 602 is rotatably connected to a hexagonal roller 603, and the back of the fixed plate 602 is fixedly installed with a winding motor 604, the output end of the winding motor 604 is fixedly connected to the hexagonal roller 603, and one end of the hexagonal roller 603 is threadedly connected to a limiting ring 605.

[0047] When the fabric is being napped, the hexagonal roller 603 on one side of the napping box 1 drives the cloth roller to rotate and moves the fabric wrapped on the cloth roller to the inside of the napping box 1. At the same time, the hexagonal roller 603 on the other side drives the corresponding cloth roller to rotate and reel in the fabric that has completed the napping operation. The inner wall of the cloth drum for reeling in the fabric can be set to a hexagonal shape corresponding to the hexagonal roller 603. This setting allows the cloth roller to be directly put on the outer surface of the hexagonal roller 603 when installing it on the winding assembly 6, and then the limiting ring 605 rotates one end of the hexagonal roller 603 to limit the cloth roller. The entire installation process is relatively convenient.

[0048] In one embodiment, for the above-mentioned wool pulling box 1, the front of the wool pulling box 1 is rotatably connected to a box door 10, and an observation slot 11 is opened on the front of the box door 10.

[0050] Through the above technical solution, 1. By arranging the napping component 3 and the suction component 4 inside the napping box 1, and the fabric can pass through the interior of the napping box 1 through the material trough 7, under the cover of the napping box 1, the broken hairs generated by the napping component 3 when the fabric is napped will not float out from the interior of the napping box 1, and the suction component 4 is arranged on the rear side of the napping component 3, and the interior of the collecting component 5 is in a negative pressure state, so that when the fabric that has completed the napping operation passes between the suction components 4, the collecting component 5 can absorb and clean the broken hairs on the upper and lower surfaces of the fabric and the broken hairs floating inside the napping box 1 through the suction component 4, so that there are no broken hairs on the upper and lower surfaces of the fabric after the fabric moves out of the interior of the napping box 1. The above arrangement ensures that the broken hairs generated when the fabric is napped only exist inside the napping box 1, so that the staff will not suffer from respiratory diseases due to the presence of broken hairs.

[0051] 2. By starting the hydraulic cylinder 201, the mounting plate 202 is driven by the hydraulic cylinder 201 to move upward. At the same time, the mounting plate 202 drives the upper napping roller 302 and the upper suction cover 401 to move through the mounting frame 301 and the upper suction tube 402, thereby increasing the distance between the upper napping roller 302 and the lower napping roller 304 and the distance between the upper suction cover 401 and the lower suction cover 403. In addition, the box door 10 can be opened, making it more convenient to pass the fabric through the napping box 1.
