Description

Technical Field

[0001] This utility model relates to the technical field of napping rollers for napping machines, and in particular to a replaceable napping roller for a napping machine. Background Technology

[0002] A napping machine is a device used to treat the surface of fabrics, primarily to remove fuzz and improve the fabric's feel and texture. Fuzz may appear during the fabric production process, affecting the fabric's appearance and feel. Therefore, a napping machine is used to remove this fuzz, resulting in a smoother fabric surface.

[0003] An existing car seat cover fabric napping machine (publication number: CN108893921A) can clean the napping rollers with a brush, but the napping rollers usually need to be fixed to the main body of the napping machine with multiple bolts or welds. Therefore, when the napping rollers are worn or malfunction, the disassembly operation is cumbersome for the staff and it is not convenient to replace them quickly, which affects work efficiency. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a replaceable napping roller for a napping machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A replaceable napping roller for a napping machine includes a napping machine frame, a mounting frame, and a napping roller. A drive motor is fixedly mounted on the outer wall of the napping machine frame. A connecting rod is fixedly mounted on the output shaft of the drive motor. A fixing sleeve is fixedly mounted on the end of the connecting rod away from the drive motor. A placement groove is provided on the mounting frame. A positioning shaft is movably disposed in the placement groove. One end of the positioning shaft is fixedly connected to the napping roller and embedded in the interior of the fixing sleeve. A through groove is provided on the fixing sleeve. A fixing frame is fixedly mounted on the outer wall of the through groove. A screw is movably disposed on the fixing frame. A rectangular block is mounted on the bottom end of the screw via a rotating shaft. A rectangular groove is provided on the positioning shaft, and the rectangular block is fitted into the rectangular groove.

[0007] As a further embodiment of this utility model, a first fixing sleeve is provided at the end of the mounting bracket away from the second fixing sleeve, and a first positioning shaft is fixedly installed at the end of the brushing cylinder near the first fixing sleeve.

[0008] As a further embodiment of this utility model, the upper end of the placement slot is fitted with a plastic buckle via a hinge, and the placement slots are symmetrically distributed on the mounting frame.

[0009] As a further embodiment of this utility model, the positioning shaft is embedded inside the fixed sleeve, and the outer wall of the fixed sleeve is connected to the roughening frame via a rotating shaft.

[0010] As a further embodiment of this utility model, a button is fixedly provided at the top of the screw, the rectangular blocks are symmetrically distributed on the roughening machine frame, and a screw sleeve is fixedly provided on the inner wall of the fixing frame.

[0011] As a further embodiment of this utility model, the mounting bracket is connected to the roughening machine frame by fasteners, and the screw is threadedly connected to the threaded sleeve.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] When installing the brushing cylinder, pull open the two sets of plastic clips to insert positioning shaft one and positioning shaft two into the two placement slots on the mounting bracket, respectively. Then close the two sets of plastic clips to initially position the brushing cylinder on the mounting bracket. Push the two sets of positioning shafts into fixing sleeve one and fixing sleeve two, respectively. Then turn the button to rotate the screw with the help of the threaded sleeve, pushing the rectangular block down to insert into the rectangular slot. Rectangular blocks are provided in both fixing sleeve one and fixing sleeve two. After fixing the two sets of positioning shafts in sequence, the brushing cylinder is then installed and fixed. On the roughening machine frame, with the cooperation of the rotating shaft, the drive motor is started, causing the drive motor to drive the connecting rod to rotate through the output shaft. At the same time, the roughening cylinder between the fixed sleeve one and the fixed sleeve two rotates, so that the roughening cylinder roughens the surface of the material. When the roughening cylinder needs to be replaced, simply turn the button in the opposite direction to make the screw move the rectangular block upward and separate it from the rectangular groove. This releases the limit on the positioning shaft one and the positioning shaft two in sequence. Finally, open the plastic buckle to remove the roughening cylinder from the mounting frame, providing convenience for workers to disassemble and assemble, and improving work efficiency.

[0034] In use, rectangular grooves 6 are provided on both the first positioning shaft 7 and the second positioning shaft 8.

[0035] From the above description, it can be seen that the above-described embodiments of this utility model achieve the following technical effects: When it is necessary to install the brushing cylinder 3, by pulling open the two sets of plastic buckles 201, the positioning shaft rod 1 7 and the positioning shaft rod 2 8 are respectively placed into the two sets of placement slots 5 on the mounting frame 2. Then, the two sets of plastic buckles 201 are closed, thereby initially positioning the brushing cylinder 3 on the mounting frame 2. The two sets of positioning shaft rods are pushed into the fixing sleeve 1 101 and the fixing sleeve 2 103 respectively. Then, the button 301 is turned, and with the cooperation of the screw sleeve 303, the screw 203 is rotated, and the rectangular block 302 is pushed down to be inserted into the rectangular slot 6. Rectangular blocks 302 are provided in both the fixing sleeve 1 101 and the fixing sleeve 2 103. The two sets of positioning shaft rods are operated in sequence. After the shaft is fixed, the brushing cylinder 3 is then installed and fixed on the brushing machine frame 1. Finally, with the cooperation of the rotating shaft, the drive motor 102 is started, causing the drive motor 102 to drive the connecting rod 104 to rotate through the output shaft. At the same time, the brushing cylinder 3 between the first fixed sleeve 101 and the second fixed sleeve 103 rotates, so that the brushing cylinder 3 brushes the material surface. When the brushing cylinder 3 needs to be replaced, simply turn the button 301 in the opposite direction to make the screw 203 move the rectangular block 302 upward and separate it from the rectangular groove 6. This releases the limit on the first positioning shaft 7 and the second positioning shaft 8 in sequence.
