The working principle and the process of the rewinding device after the roll paper is cut are as follows:
the unreeling machine 2 adopts an active unreeling mode, the unreeling shaft 21 is driven by an unreeling motor 22, and the unreeling motor 22 sends a signal to a frequency converter after the distance measuring sensor 5 detects the distance of the paper 100 so as to control the rotating speed of the unreeling motor 22. When the distance between the paper 100 and the distance measuring sensor 5 is small, the rotating speed of the unreeling motor 22 is slowed down; when the distance between the paper 100 and the distance measuring sensor 5 is large, the rotation speed of the unwinding motor 22 becomes fast. Since the compressed air in the blow pipe 3 is blown downward against the paper 100, the paper 100 is always floated at a certain height between the pair of paper blocking plates 6. The pair of paper blocking plates 6 mainly control the floating paper 100 within a range that can be detected by the distance measuring sensor 5.
The end face of the unreeled reel paper is not flat, the paper coming out can also transversely drift, in the rewinding process, the floating paper can transversely move freely and can also be fixed due to the floating of the paper, when the paper passes through the paper blocking blocks 76 on the two sides of the paper sucking platform 7, the paper 100 can be transversely fixed, the adjusted paper can be transversely and relatively static through the air suction of the paper sucking platform 7, the fixed paper is adsorbed on the surface of the platform panel 70, and the paper can stably enter between the pair of damping rollers 8.
Because final reel wrapping paper must tighten up, but the paper of float can not directly be rolled up, and the paper needs to keep certain tension in the rolling in-process, so rolling axle 10 needs a pair of damping roller 8 to control the tension of paper when rolling, consequently connects magnetic powder brake 80 at the axle rear end of damping roller, can set for the tension size of paper through magnetic powder brake 80.
The sheet 100 coming out of the pair of damper rollers 8 passes under the first rear guide roller 43 and under the second rear guide roller 44, and reaches the left side of the air blowing roller 9, and the air blowing roller 9 blows the sheet with tension again on the roller surface because the compressed air with higher pressure in the air blowing roller 9 is blown out from the surface of the inner half 913 of the inner positioning loop 91. The transverse position of the sheet 100 is determined by adjusting the inner positioning ring 91 on the air blowing roller 9, i.e. the first nut 93 is adjusted first, and after the position of the positioning flange 911 of the inner positioning ring 91 on the roller core 90 is determined, it is locked by the third nut 95. The distance between the outer end face of the positioning flange 911 of the inner positioning ring 91 and the inner end face of the outer positioning ring 92 for the paper 100 to pass through can be adjusted by adjusting the outer positioning ring 92, the distance is the width L of the paper 100, and the paper 100 is locked by the second nut 94 after being adjusted, so that the transverse position of the paper 100 is accurately positioned again and then enters the take-up shaft 10.
The paper floats on the roller surface for the first time through the air blowing pipe 3, the coarse positioning is realized, and the paper floats on the roller surface for the second time through the air blowing roller 9, so that the purpose of flattening the end surface of the roll paper is realized.
The winding is in a surface winding mode, the speed of the main paper conveying roller 3 is controlled by a variable frequency motor, and the speed can be set arbitrarily according to the designed speed. The speed of the main transfer roller 3 is also the speed of the whole machine. In the winding process, the surface of the winding shaft 10 is pressed against the surface of the main paper conveying roller 3, and the winding shaft 10 is driven to rotate by the main paper conveying roller 3. The pressure of the winding shaft 10 is set by the air pressure of the air cylinder 13, and the air pressure of the air cylinder 13 can be adjusted at will according to the requirements of paper and the process.
The rewinding device after web slitting of the invention uses two times of air blowing to control the paper to move transversely or be fixed, so as to achieve the purpose of flattening the end surface of the reel paper. The paper can float through the first air blowing, and the coarse positioning of the paper is realized; the roughly positioned paper can be transversely and relatively static through the air suction platform, and the end surface flatness of the roll paper can be effectively improved; a pair of damping rollers is used for enabling the paper to have certain tension; and the accurate positioning of the paper is realized through secondary air blowing. The web after rewinding by the rewinding device can effectively improve the end surface flatness of the web and meet the requirement of packaging. The rewinding device can also greatly reduce the manufacturing cost.
