Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] When implementing: Figure 1-4As shown, a napping machine for double-sided napping of flannel fabrics comprises: a mounting platform 1, the upper end of the mounting platform 1 is rotatably connected to two napping rollers 2, the two napping rollers 2 are placed parallel to the upper side of the mounting platform 1, the side end of the mounting platform 1 is fixedly connected to a driving mechanism 3, the output end of the driving mechanism 3 is detachably connected to one of the napping rollers 2; a quick replacement mechanism 6, the quick replacement mechanism 6 for quickly disassembling the two napping rollers 2 is arranged on one side of the mounting platform 1; wherein the quick replacement mechanism 6 is provided with two groups, each group of the quick replacement mechanism 6 comprises a connecting component 601 arranged on one side of the mounting platform 1, an auxiliary fixing component 602 is arranged on the lower side of the connecting component 601, the napping rollers 2 are driven by the driving mechanism 3 to nap and raise the flannel fabric, and when the napping rollers 2 need to be replaced after being used for napping for a period of time, they are initially unlocked by the auxiliary fixing component 602, and then The auxiliary fixing component 602 drives the connecting component 601 to rotate and unlock the napping roller 2. At this time, the napping roller 2 can be directly lifted up to remove and replace the curved needles and brushes on the surface. After replacement, the napping roller 2 is placed and installed. At this time, the napping roller 2 is locked by the connecting component 601 and the auxiliary fixing component 602. At this time, the replacement of the curved needles and brushes on the surface of the napping roller 2 is completed. The two napping rollers 2 are placed and installed on the upper side of the mounting platform 1. When the connecting component 601 is removed, the napping roller 2 can be placed stably without falling off, which is convenient for replacement. The mounting platform 1 has an arc-shaped mounting groove for placing and installing the bearing part of the napping roller 2. The napping roller 2 includes curved needles, brushes and rotating bearings fixed at both ends on the surface. The driving mechanism 3 is driven by a motor to drive two gears to make the two napping rollers 2 rotate relative to each other. Because the driving mechanism 3 is the same as the power component part in the comparative document, no further description is given.

[0024] like Figure 2 and Figure 4As shown, the connection assembly 601 includes a downward pressing fixing frame 6011 movably hinged to the upper end of the mounting platform 1, a fixed plug rod 6012 is slidably connected to the side end of the mounting platform 1, a first rotating seat 6014 is fixedly connected to the side end of the mounting platform 1, a lead screw 6015 is rotatably connected to the inner wall of the first rotating seat 6014, a nut 6013 is threadedly connected to the surface of the lead screw 6015, and a fixed plug rod 6012 is fixedly connected to the side end of the nut 6013, a connecting groove 6018 is opened at the upper end of the mounting platform 1, and the fixed plug rod 601 2 is movable through the lower end of the downward pressing fixed frame 6011 and extends downward to slide and engage with the inner wall of the connecting groove 6018. When the napping roller 2 needs to be installed or removed, the lead screw 6015 can be rotated, so that the lead screw 6015 drives the nut 6013 to rotate, and the nut 6013 drives the fixed plug rod 6012 to rise until the fixed plug rod 6012 is away from the downward pressing fixed frame 6011. At this time, the napping roller 2 can be exposed by flipping the downward pressing fixed frame 6011. At this time, the two sets of connecting components 601 The first rotating seat 6014 is fixedly connected to the side end of the "L"-shaped stabilizing rod 6017, and the lead screw 6015 is rotatably connected to the inner wall of the "L"-shaped stabilizing rod 6017. When the lead screw 6015 rotates, the upper side of the lead screw 6015 is easy to swing. The rotation of the lead screw 6015 is limited by the "L"-shaped stabilizing rod 6017, so that when the lead screw 6015 rotates, it is not easy to swing. The lower end of the fixed rod 6017 is fixedly connected to a sliding rod 6016, and the lower end of the sliding rod 6016 movably passes through the lower end of the nut 6013 and is fixedly connected to the upper end of the first rotating seat 6014 looking downward. When the lead screw 6015 rotates to drive the nut 6013 to move up and down, the nut 6013 is likely to swing following the rotation of the lead screw 6015. The sliding of the nut 6013 is limited by the sliding rod 6016, so that the nut 6013 is limited when sliding up and down, and the nut 6013 is not likely to swing when sliding.

[0025] like Figure 2 and Figure 3As shown, the auxiliary fixing component 602 includes a second rotating frame 6021 fixedly connected to the side end of the mounting platform 1, the inner wall of the second rotating frame 6021 is rotatably connected to a worm 6022, the circumferential surface of the lead screw 6015 is fixedly connected to a worm wheel 6023, the worm wheel 6023 is meshed and connected with the worm 6022, when the connecting component 601 is fixed, the lead screw 6015 is easy to rotate by itself, so that the napping roller 2 shakes in the mounting platform 1, reducing the stability of the fixation, and the worm wheel 6023 and the lead screw 6015 are driven to rotate by the worm 6022, and the rotation of the worm wheel 6023 is self-locked, so that the fixation of the connecting component 601 is more stable, and the upper end of the mounting platform 1 is threadedly connected with a fixing bolt 6024, and the fixing bolt 6024 movably passes through the lower end of the downward pressing fixing frame 6011 and extends downward. 011 is relatively long, and the middle part is pressed and fitted only by its own shape, which is easy to deform and cause the napping roller 2 to shake. The middle parts of the two napping rollers 2 can be fixed by fixing bolts 6024 to reduce the shaking of the napping rollers 2 when rotating. The surface of the fixing bolts 6024 is rotatably connected with a lower pressing plate 6025, and the lower pressing plate 6025 is arranged between the two napping rollers 2. The lower pressing plate 6025 can increase the pressing area and increase the fixed pressing effect. The inner wall of the mounting platform 1 is rotatably connected with a rotating shaft 5, and the surface of the rotating shaft 5 is fixedly connected with a guide roller 4. Because the two napping rollers 2 are placed in parallel, when the cloth is pulled and rolled, it will fit one of the napping rollers 2, affecting the napping effect. The pulling direction of the cloth can be adjusted by the guide roller 4 and the rotating shaft 5 to increase the fitting processing effect of the two napping rollers 2 on the cloth.

[0026] When the utility model is in use, when the flannel cloth is napped by the device, the cloth can be placed between the two napping rollers 2, and then the driving mechanism 3 is manually started, and the driving mechanism 3 drives the two napping rollers 2 to rotate relatively, and the napping rollers 2 can nap and raise the flannel cloth. When the napping rollers 2 are used for a period of time, they need to be replaced. At this time, the driving mechanism 3 is manually closed so that the rotation of the two napping rollers 2 stops, and the fixing bolt 6024 is removed at this time, and then the worm 6022 is rotated, so that the worm 6022 drives the worm wheel 6023 and the lead screw 60 15 rotates, so the screw 6015 drives the nut 6013 to rotate, and the nut 6013 drives the fixed rod 6012 to rise until the fixed rod 6012 is away from the downward pressing fixed frame 6011. At this time, the downward pressing fixed frame 6011 can be turned over to expose the roughening roller 2. At this time, both sets of connecting components 601 are unlocked, and the roughening roller 2 can be lifted for replacement. When the replacement is completed, the downward pressing fixed frame 6011 covers the surface of the roughening roller 2, and the screw 6015 is rotated in the opposite direction. At this time, the downward pressing fixed frame 6011 fixes the roughening roller 2, and the replacement is completed.

[0027] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
