The block 434 limits the ratchet 432, and the ratchet 432 rotates clockwise so that the ratchet 432 pushes the block 434 back into the outer tube 433. The spring B435 keeps the block 434 fit with the ratchet 432, and the ratchet 432 rotates counterclockwise so that the block 434 blocks the teeth of the ratchet 432, and the ratchet 432 cannot rotate counterclockwise, thereby making the material belt passing through the two limiting rollers 42 can only continue to be transported to the left and cannot fall, thereby improving the belt winding efficiency. Stability, so that the reel 221 will not rotate counterclockwise, and the belt will not pull the reel 221 to reverse due to the excessive weight on the right side, thereby preventing the belt from falling off the reel 221. There is also a part of the belt in the gap between the limiting roller 42 and the reel 221. The gravity of the belt cannot pull the reel 221 to rotate, and the belt has toughness. A part of the belt between the limiting roller 42 and the reel 221 needs to be folded before it is possible to pull the reel 221 to rotate under the force of gravity. The elasticity of the belt makes the pressure required for folding the belt greater, which also makes it impossible for the belt to pull the reel 221 to rotate.

[0038] Working principle: When the device is in use, first rotate the screw rod 212 on the outside of the screw sleeve 213 so that the two screw sleeves 213 are separated from the corresponding screw rods 212, then rotate the upper card shell 211, place the roller 223 on the bottom card shell 211, and the two lower card shells 211 support the roller 223, then rotate the upper card shell 211 to fit with the lower card shell 211, so that each group of two screw rods 212 fit together, then screw the screw sleeve 213 on the outside of each group of two screw rods 212, limit the two screw rods 212 of each group, fix the two card shells 211 of each group, and limit the circumferential position of the roller 223 of each group with the two card shells 211, and then pass the belt from the left side of the side frame 41 through the two limiting rollers 42, The limiting roller 42 fits tightly with the belt, and the spring B435 in the outer tube 433 pushes the block 434 to fit with the ratchet 432. The block 434 limits the ratchet 432, and the ratchet 432 rotates clockwise so that the ratchet 432 pushes the block 434 back into the outer tube 433. The spring B435 keeps the block 434 fit with the ratchet 432, and the ratchet 432 rotates counterclockwise to jam the block 434 and the ratchet 432. The ratchet 432 cannot rotate counterclockwise, so that the material belt passing through the two limiting rollers 42 can only continue to be transported to the left and cannot fall, thereby improving the stability of the belt winding, and thus preventing the reel 221 from rotating counterclockwise, so that the belt will not pull the reel 221 to reverse due to the excessive weight on the right side, thereby preventing the belt from reeling off the reel 221. 21 falls off, and there is also a part of the belt between the limiting roller 42 and the reel 221. The gravity of the belt cannot pull the reel 221 to rotate, and the belt has toughness. A part of the belt between the limiting roller 42 and the reel 221 needs to be folded before it is possible to pull the reel 221 to rotate under gravity. The elasticity of the belt makes it necessary to have a large pressure when folding the belt, which also makes it impossible for the belt to pull the reel 221 to rotate. When winding, insert one end of the belt into the slot, then use a screwdriver to insert the operating slot and turn the bolt 231. The bolt 231 moves to the left in the adjusting slot, and the bolt 231 drives the clamping plate 232 to move to the left. The clamping plate 232 clamps the belt in the slot, so that the end of the belt is fixed when the belt is wound, and the operation is simple. The spring seat 331 is rotated to drive the sleeve 332 to rotate, so that the transmission groove of the sleeve 332 is aligned with the transmission block 34, and the spring A334 pushes the sleeve 332 so that the sleeve 332 is sleeved on the outside of the roller 223, and the transmission block 34 is placed on the inside of the transmission groove. At this time, the motor 32 on the support plate 31 runs to drive the spring seat 331 to rotate, and the spring seat 331 drives the sleeve 332 to rotate through the limit block 333, and the sleeve 332 drives the roller 223 to rotate through the limit of the transmission block 34 in the rotation groove. The rotation of the roller 223 drives the reel 221 to rotate, and the reel 221 rewinds the belt. The limit plate 222 limits the belt to avoid tilting and winding when the belt is rewound, which facilitates the connection and disassembly of the transmission.After winding is completed, the sleeve 332 is pulled away from the roller 223, and the housing 211 is opened to facilitate the removal of the reel 221 with the belt material, which is convenient for loading and unloading and subsequent transportation. The operation is simple and the transmission connection is convenient, which improves the convenience of assembling a new coil assembly 22 of the device.
