Detailed implementation manners

[0019] The present utility model will be further described below with reference to the accompanying drawings:

[0020] As Figures 1 to 6 shown, this embodiment provides a fabric winding device for a circular knitting machine, including a frame 1, a mounting frame 2 fixedly connected to the frame 1, a winding mechanism installed at the lower part of the frame 1, and a rotating base 102 installed at the bottom end of the frame 1. An annular connecting frame 201 is provided in the middle of the mounting frame 2. A plurality of annularly arranged elastic clamping members are installed on the top of the annular connecting frame 201. The elastic clamping members include a U-shaped base 207 fixedly connected to the annular connecting frame 201 and two movable chucks 208 oppositely installed on the U-shaped base 207. Two adjusting screws 209 are oppositely provided on the U-shaped base 207. The adjusting screw 209 horizontally penetrates through a vertical wall of the U-shaped base 207. Two adjusting nuts 210 are sleeved on the adjusting screw 209. The two adjusting nuts 210 are respectively arranged on both sides of the vertical wall. The movable chuck 208 penetrates through the adjusting screw 209 and is in sliding fit with the adjusting screw 209. A compression spring 211 is sleeved on the movable chuck 208. The two ends of the compression spring 211 respectively abut against the head of the movable chuck 208 and the adjusting screw 209. The fabric winding device of the circular knitting machine in this embodiment can achieve quick connection with the needle cylinder and is convenient for disassembly and assembly in the later stage.

[0021] In this embodiment, an upper roller shaft 202 is installed inside the annular connecting frame 201, and a spreading bar 3 is installed on the frame 1 below the annular connecting frame 201. A cutting knife 203 is provided at one end of the upper roller shaft 202. The cutting knife 203 can be adjusted in position along the axial direction of the upper roller shaft 202. A guide bar 204 is provided on each side of the upper roller shaft 202. Both ends of the cutting knife 203 are slidably engaged with the corresponding guide bar 204 through sliding sleeves 205. A third locking bolt 206 is inserted through each sliding sleeve 205, and the end of the third locking bolt 206 abuts against the guide bar 204. When the fabric passes through the upper roller shaft 202, the cutting knife 203 cuts the annular fabric, and the cut fabric is stretched when passing through the spreading bar 3, so that single-layer fabric winding can be carried out.

[0022] The spreading bar 3 in this embodiment is L-shaped. Both ends and the middle of the spreading bar 3 are connected to the frame 1 through connecting rods 301. A horizontal bar 101 is provided on the frame 1, and an adjusting mechanism for cooperating with the connecting rod 301 is provided at the top of the horizontal bar 101. The adjusting mechanism includes a first open shaft sleeve 302 fixed on the horizontal bar 101 and a rotating shaft 306 rotatably installed on the first open shaft sleeve 302. A first locking bolt 303 is provided on the first open shaft sleeve 302. The rotating shaft 306 is inserted into the first open shaft sleeve 302. The connecting rod 301 is connected to the middle of the rotating shaft 306 through a connecting block 307. A second open shaft sleeve 304 is provided at the upper end of the connecting block 307. A second locking bolt 305 is provided on the second open shaft sleeve 304. The connecting rod 301 is inserted into the second open shaft sleeve 304. By loosening the first locking screw, the angle of the spreading bar 3 can be adjusted, and by loosening the second locking screw, the extending length of the spreading bar 3 can be adjusted. Thus, the spreading bar 3 can be adjusted to match fabrics of different widths.

[0023] The rewinding mechanism of this embodiment includes a cloth supporting roller 4 and a rewinding roller 5. The cloth supporting roller 4 is rotatably installed on the frame 1 below the fabric spreading bar 3 and is driven to rotate by a first driving mechanism. The rewinding roller 5 is rotatably installed on the frame 1, and the rewinding roller 5 is rotatably installed on the frame 1 below the cloth supporting roller 4 and is driven to rotate by a second driving mechanism. The cloth supporting roller 4 is used to spread the opened fabric. The second driving mechanism includes two relatively arranged turntables 6 and a driving motor for driving the two turntables 6 to rotate. Both ends of the rewinding roller 5 are respectively abutted against the two turntables 6. Each turntable 6 is provided with an abutting cylinder 603 and an abutting block 602. A chute 601 extending along the diameter direction of the turntable 6 is formed on the turntable 6. The depth of the chute 601 gradually decreases in the direction pointing to the center of the turntable 6. The abutting block 602 is slidably installed in the chute 601. The abutting cylinder 603 is installed on the turntable 6 and drives the abutting block 602 to move. When the fabric on the rewinding roller 5 accumulates to a certain thickness, the piston rod of the abutting cylinder 603 contracts, the abutting block 602 moves away from the center of the turntable 6, and gradually moves away from the rewinding roller 5, and the rewinding roller 5 then falls off from the two turntables 6. When replacing the new rewinding roller 5, both ends of the rewinding roller 5 are placed at the center of the turntable 6, and the abutting cylinder 603 drives the abutting block 602 to move towards the center of the turntable 6, and the abutting block 602 can then press the rewinding roller 5 tightly to realize the fixation of the rewinding roller 5. The unloading, installation and replacement of the cloth roll and the rewinding roller 5 are very convenient.

[0024] When the cloth rolling device of the circular knitting machine of this embodiment is in use, both ends of the connecting piece are abutted between the two movable chucks 208 of the elastic clamping piece, so as to realize the transmission connection between the needle cylinder and the rewinding mechanism. The needle cylinder drives the rewinding mechanism to rotate, and the rewinding mechanism performs fabric spreading and rewinding on the woven fabric.
