[0001] The utility model relates to a rotary tower type non-stop winding mechanism, belonging to the technical field of roll changing of a winding station of a printing machine. Background Art

[0002] The printing press rewinding station is an indispensable part of the printing press. When the existing printing press rewinding station is rewinding, when a paper roll is rewound, it is necessary to manually replace the paper roll. When changing the roll, it is necessary to slow down or stop the machine for operation, which affects the output and generates more paper waste. In addition, the paper roll received on the rewinding roller is not compact enough and the edges of the paper are not aligned, which affects the rewinding quality and causes the next process to proceed unsmoothly.

[0003] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0004] In view of the deficiencies in the background technology, the utility model provides a rotating tower type non-stop winding mechanism, which can automatically wind the paper onto the next paper roll without stopping or slowing down after the paper roll is full, without manual operation, and has high work efficiency; it also makes the paper roll on the winding roller compact and neat, and the winding quality is good.

DETAILED DESCRIPTION

[0024] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation methods of the utility model are now described with reference to the accompanying drawings.

[0025] like Figure 1-3 As shown, the utility model provides a rotating tower type non-stop winding mechanism, including two rotating disks 1, a plurality of winding rollers 2 are axially installed between the two rotating disks 1, the rotating disks 1 are rotatably installed on the turret wall panels 3 on both sides thereof, a worm gear 4 is fixed on the rotating shaft of the rotating disk 1, the worm gear 4 is matched with a worm 5 for transmission, and the worm 5 is driven by a motor.

[0026] Two fixed outer plates 9 are provided on one side of the rotating disk 1, and a paper cutting assembly is provided between the two fixed outer plates 9. The paper cutting assembly includes a cutter 15. When the winding roller 2 on the rotating disk 1 is full of paper, the rotating disk 1 rotates to make the empty winding roller 2 rotate to the cutter 15, and the cutter cuts the paper. At the same time, the paper is wound around the empty winding roller 2, thereby realizing automatic roll changing without stopping the machine.

[0027] The paper cutting assembly also includes two cutter hanging plates 13, each of which is slidably installed on the inner side of the fixed outer plate 9 through a slide rail, a cutter fixing arm 14 is fixed at the front end between the two cutter hanging plates 13, and a cutter 15 is mounted on the cutter fixing arm 14, and a cutting cylinder 11 is correspondingly installed on each fixed outer plate 9, the telescopic rod of the cutting cylinder 11 is hinged to the cutter hanging plate 13, the telescopic rod of the cutting cylinder 11 is extended, and the cutter 15 is pushed to cut the paper.

[0028] A roller hanging plate 8 is slidably mounted on the inner side of each fixed outer plate 9 , a connecting plate 7 is fixed between the two roller hanging plates 8 , and the connecting plate 7 fixes the two roller hanging plates 8 , and a roller 6 is installed at the front end between the two roller hanging plates 8 .

[0029] A pressure roller cylinder 10 is also installed on the inner side of each fixed outer plate 9. The telescopic rod of the pressure roller cylinder 10 is hinged with the corresponding pressure roller hanging plate 8. The telescopic rod of the pressure roller cylinder 10 extends to push the pressure roller 6 to press on the winding roller 2 on the front side.

[0030] Furthermore, there are two sets of paper cutting components, which are respectively located on the upper side and the lower side of the fixed outer plate 9.

[0031] A guide roller 12 is rotatably mounted between the two fixed outer plates 9 for conveying the paper tape.

[0032] Preferably, two winding rollers 2 are axially installed between the two rotating disks 1, and the outer sides of the winding rollers 2 are coated with adhesive.

[0033] The specific working principle of the utility model:

[0034] A plurality of winding rollers 2 are axially installed between the two rotating disks 1. When one of the winding rollers 2 is used for winding, the paper is transported to the winding roller 2 through the guide roller 12. When the winding roller 2 is full of paper, the paper is not cut first. The motor drives the rotating disk 1 to rotate, so that the next empty winding roller 2 turns to the paper winding position, and the full winding roller 2 turns away. At this time, the telescopic rod of the pressure roller cylinder 10 extends to push the pressure roller 6 to press on the empty winding roller 2 on the front side. Then, the telescopic rod of the cutting cylinder 11 on one side extends to push the cutter 15 to cut the paper (the conveying direction of the paper is different, and the upper or lower paper cutting assembly is selected for cutting as needed).

[0035] After cutting, since the outer side of the winding roller 2 is coated with adhesive, the pressure roller 6 sticks the paper to the hole of the winding roller 2 and continues to reel. The whole process does not require stopping or slowing down. After the full winding roller 2 turns away, the paper tape is in a taut state, there will be no loose problems, and the winding quality is good.

[0036] The above is an example of the best implementation of the utility model, and the parts not described in detail are common knowledge of ordinary technicians in this field. The protection scope of the utility model is based on the content of the claims, and any equivalent transformation based on the technical inspiration of the utility model is also within the protection scope of the utility model.
