[0039] Working principle: First, the cotton strips pass through the cotton strip feeding wheel 23, the feeding slide 21, the feeding tube 31, the two squeezing feeding rollers 32, the clamping mechanism 4 on the upper side and one of the clamping mechanisms 4 on the lower side in sequence, and the cotton strips are clamped between the two squeezing feeding rollers 32;

[0040] Second, the first motor 24 drives the sliver feeding wheel 23 to rotate, and the sliver feeding wheel 23 drives the sliver to be transported to the feeding slideway 21;

[0041] Third, the second motor drives one of the squeeze feed rollers 32 to rotate, and the squeeze feed roller 32 drives the other squeeze feed roller 32 to rotate in the opposite direction through two mutually meshing gears 34. The two squeeze feed rollers 32 convey the cotton strips downward and pass through the feed hole 411 of the base plate 41. The length of the cotton strip conveyed is controlled by the number of turns of the motor shaft of the second motor.

[0042] Fourth, when the cotton strips under the two squeezing conveying rollers 32 reach the required length, the piston rods of the third cylinder 48 of the clamping mechanism on the upper side and one of the clamping mechanisms on the lower side are contracted, and the driving disk 43 is driven to rotate a certain angle through the pushing portion 47, the push-pull arm 46 and the push-pull shaft 45. The multiple arc grooves 431 of the driving disk 43 drive the multiple moving clamping blocks 44 to simultaneously drive the center of the disk 43 to move through the cylinder 411, thereby clamping the cotton strips between the inner ends of the multiple moving clamping blocks 44, and the cotton strips are clamped between the clamping mechanism on the upper side and one of the clamping mechanisms on the lower side. Then, the piston rods of the two lifting cylinders corresponding to the clamping mechanism on the lower side are contracted to drive the clamping mechanism on the lower side to move downward, thereby tearing the cotton strips between the two clamping mechanisms on the upper side, and the lower ends of the torn cotton strips are pressed against the rounding part of the corresponding end rounding mechanism on the lower side.

[0043] Fifth, the third cylinder 48 of the upper clamping mechanism is extended, and the movable clamp block 44 moves outward and releases the restraint on the torn sliver;

[0044] Sixth, the piston rod of the second cylinder 79 extends, pushing the moving frame 76 to move left, and the moving frame 76 drives the two clamping mechanisms on the lower side and the two end rounding mechanisms 5 on the lower side to move left, and the end rounding mechanism 5 on the left side below moves to just below the end rounding mechanism 5 on the left side above, and the end rounding mechanism 5 on the right side below moves to the position of the end rounding mechanism 5 on the left side below just now (that is, the ball and socket hole 511 of the rounding part 51 of the end rounding mechanism 5 on the right side below is coaxially arranged with the feeding pipe 31), and then the piston rod of the cylinder 72 on the left side pushes the lifting seat 71 on the left side to move down along the slide rail, and the lifting seat 71 on the left side drives the rounding part of the end rounding mechanism 5 on the left side above to move down, and while moving down, the motors 54 of the two end rounding mechanisms 5 on the left side are turned on, and the motors 54 drive the rounding part 51 of the end rounding mechanism to rotate, so that the ball and socket holes 511 of the two rounding parts 51 round the two ends of the torn cotton strips;

[0045] Seventh, while the two end rounding mechanisms 5 on the left are rounding the torn cotton strips, the cotton strip feeding mechanism, the fixed-length cutting and shaping mechanism continue to work in the second, third and fourth steps mentioned at the same time, and the newly torn cotton strips are placed on the rounding part 51 of the end rounding mechanism on the right side below. After the two end rounding mechanisms 5 on the left have completed the rounding work, the piston rod of the second cylinder 79 contracts, driving the moving frame 76 to move right and reset, and the end rounding mechanism 5 on the right side below moves to just below the end rounding mechanism 5 on the right side above, and then the end rounding mechanism 5 on the right side above moves down to round the two ends of the newly torn cotton strips, and then the second clamping mechanism on the left releases the restraint on the cotton ball on the left;

[0046] Eighth, the air pipe 81 is inflated, and the air pipe 81 blows the rolled cotton balls on the left side onto the discharge conveyor belt 82, and the discharge conveyor belt 82 transports the rolled cotton balls to the next process.

[0047] Finally, the above implementation modes are only used to illustrate the present invention, and are not intended to limit the present invention. Ordinary technicians in the relevant technical field may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be defined by the claims.
