Problems solved by technology

Usually, when this type of paper roll rewinder rewinds coreless paper rolls, the base paper is wound around the lower roll surface of the upper winding roll, and passes through the upper and lower rolls as the upper winding roll rotates. The gap between the winding rollers comes to the paper roll rewinding area to accumulate and roll, because the base paper of this type of paper roll rewinder is piled up and rolled, and generally needs to be piled up to a large thickness before rolling, which makes the production out The coreless paper roll is easy to flower core and has quality problems. At the same time, because the base paper is introduced from the lower roll surface of the upper winding roll to the gap between the upper and lower winding rolls, the threading of this type of paper roll rewinding machine It is also inconvenient, and it is troublesome for workers to operate; when rewinding cored paper rolls, this type of paper roll rewinding machine first needs to adjust the gap between the upper and lower winding rollers to accommodate the paper tube supply mechanism from the bottom of the gap. The diameter of the paper tube that is dialed up, when the paper tube passes through the gap between the upper and lower winding rollers and comes to the rewinding area of ​​the paper roll, the base paper also winds around the lower roller surface of the upper winding roller, and along with the upper winding roller The rotation of the winding roller comes to the paper roll rewinding area through the gap between the upper and lower winding rollers, and then sticks to the paper tube in the paper roll rewinding area to rewind the cored paper roll. When the roll rewinder is producing cored paper rolls, it is necessary to adjust the gap between the upper and lower winding rollers, and it is necessary to ensure high-precision, high-demand debugging and calibration during adjustment, which will inevitably result in long downtime and serious affect production efficiency
In addition, when converting some existing coreless paper roll rewinders into cored paper roll rewinders, its auxiliary devices need to be removed, which requires a large workload, and it needs to be re-installed with high precision and high requirements. Debugging and correction, which will also cause long downtime, which may seriously affect production efficiency

Embodiment 1

[0031] Embodiment 1: see attached figure 1 to attach Figure 4As shown, the fully automatic rewinding machine described in this embodiment, which can continuously produce cored and coreless paper rolls without stopping the machine, includes a first winding roller 1, a second winding roller 2, and a winding pressure roller parallel to each other. 3. The paper feeding press roller 14 and the paper tube supply mechanism 4, wherein the first winding roller 1 is correspondingly arranged between the paper feeding pressing roller 14 and the second winding roller 2, and is connected with the paper feeding pressing roller respectively. 14 and the second winding roller 2 are arranged adjacent to each other and there is a gap, and the roller surface of at least one winding roller is distributed with a plurality of suction holes 17 capable of vacuum adsorption along its circumferential direction, and in this embodiment, the first The roll surface of the winding roller 1 is distributed al...

Embodiment 2

[0032] Embodiment 2: see attached Figure 5 to attach Figure 7 As shown, the difference from Example 1 is that the two-way lap roll-assisting sheathing plate 5 of this embodiment is provided with an air blowing hole 502 that can blow air to the crotch. There is a suction hole 503 at the bottom of the mouth that can be vacuumed. When coreless paper roll production is required, the base paper head that enters the rewinding area of ​​the paper roll will be sucked by the suction hole 503 first, so that it can come accurately. Two-way lapping at the mouth 504 of the roll-assisting cover plate 5, and then blowing air on the base paper head through the air blowing hole 502, so that it can be rolled up quickly; the air blowing hole 502 and the air suction hole 503 can effectively ensure that the base paper 7 Accurate, fast and reliable rolling at Yakou 504.

Embodiment 3

[0033] Embodiment 3: see attached Figure 8 to attach Figure 10 As shown, the difference from Example 1 is that the bottom of the crotch of the two-way lap roll-assisting cover plate 5 described in this embodiment is provided with a rotating wheel 10 that can hold the paper and roll it up. Through this rotating wheel 10, it can effectively ensure that the base paper 7 Fast, accurate and reliable roll-up at the mouth.

Abstract

The invention discloses a full-automatic rewinding machine capable of continuously producing a paper scroll with / without a core without halt. The full-automatic rewinding machine comprises a first coiling roller, a second coiling roller, a coiling pressing roller, a paper conveying pressing roller and a paper tube supply mechanism parallel to one another, wherein the upper roller surfaces of the first coiling roller and the second coiling roller are in lap joint through bidirectional lap joint coiling assisting plates; descending forks are formed in the bidirectional lap joint coiling assisting plates; the forks are positioned in a gap between the first coiling roller and the second coiling roller; and annular grooves which can accommodate corresponding lap covering sides of the bidirectional lap joint coiling assisting plates are formed in the roller surfaces of the first coiling roller and the second coiling roller. By adopting the scheme, a piece of body paper penetrates through the gap between the first coiling roller and the paper conveying pressing roller, is adhered to the upper roller surface of the first coiling roller, arrives at the forks of the bidirectional lap joint coiling assisting plates along with the rotation of the first coiling roller, and is subjected to kneading and coiling so as to form a paper scroll without a core, or is subjected to rewinding so as to form a paper scroll with a core in a mode that the paper tube supply mechanism supplies a paper tube to the forks; and after the rewinding, the finished paper scroll is discharged from a paper scroll outlet formed between the upper roller surface of the second coiling roller and the coiling pressing roller.

Description

technical field [0001] The invention relates to the technical field of production equipment for cored and coreless paper rolls, in particular to a fully automatic rewinder capable of continuously producing cored and coreless paper rolls without stopping the machine. Background technique [0002] With the continuous development of social science and technology, some paper roll rewinders that can continuously produce cored or coreless paper rolls appear on the market.
