Embodiment 1

[0024] see figure 1 , The coreless paper roll rewinding machine of the present invention is provided with a rewinding upper roll 1 and a rewinding lower roll 2, and an endless belt 3 for pulling paper. One end of the endless belt 3 is wound on the rewinding upper roller 1 , and the other end is wound on the tension pulley 4 . The tensioning pulley 4 tensions the endless belt 3 . The paper 5 used for rewinding into paper rolls winds around the tension wheel 4 and sticks to the belt surface of the endless belt 3 . A roll-assisting plate 6 is provided at a position close to the endless belt 3 , and a roll-up passage 7 is formed between the rolled-aid plate 6 and the endless belt 3 . Circulation belt 3 can adopt belt.

[0025] see also figure 1 , figure 2 The rolling aid plate 6 is provided with a flange 8 protruding toward the endless belt 3, and the height of the flange 8 is preferably not greater than 3 mm. The gap between the flange 8 and the endless belt 3 is small eno...

Embodiment 2

[0029] see Figure 6 In this embodiment, a liner 14 is added on the basis of the first embodiment. The liner 14 is located on the other side of the endless belt 3 relative to the rolling-assisting plate 6 , and the liner 14 abuts against the endless belt 3 . The backing plate 14 ensures that the gap between the endless belt 3 and the flange 8 of the rolling aid plate 6 will not become larger due to the elastic deformation of the endless belt 3, which improves the reliability of rolling.

Embodiment 3

[0031] see Figure 7 , In this embodiment, on the basis of Embodiment 1, a paper pressing movable part 15 is added. During the process of rewinding the paper 5 into a paper roll, the paper pressing movable member 15 does not contact the paper 5 . when Figure 7 When the rewinding of a roll of paper roll 16 shown is completed, the paper pressing movable part 15 rotates one revolution. When the platen movable part 15 rotates to Figure 7 Moment at the position shown, as Figure 8 As shown, the paper pressing movable member 15 presses the paper 5 drawn by the endless belt 3 against the endless belt 3 , thereby hindering the advancement of the paper 5 , so that the paper 5 is stretched and broken. After paper 5 is broken, Figure 7 The shown paper roll 16 rolls out from the nip between the rewinding upper roller 1, the rewinding lower roller 2 and the platen roller 11, and at the same time, the fracture of the paper 5 becomes Figure 8 Paper tip 9 shown. When the newly form...

Abstract

The invention discloses a non-core paper roll rewinding machine utilizing a circulation belt for winding. The non-core paper roll rewinding machine is provided with the circulation belt for drawing paper, one end of the circulation belt is wound around an upper rewinding roll or a lower rewinding roll, and the other end of the circulation belt is wound around a tensioning wheel; a winding assisting plate is arranged close to the circulation belt, and a winding channel is formed at the gap between the winding assisting plate and the circulation belt; and the winding assisting plate is providedwith a flange protruding towards the circulation belt, and a narrow gap is reserved between the flange and the circulation belt. Through the narrow gap between the flange and the circulation belt, theend of paper is curled to form a core of a paper roll, the formed core of the paper roll is liable to be a regular circle, and thus the rewinding quality of the paper roll is improved advantageously;and in the winding process, the number of movement parts needed for cooperation is small, the control difficulty is low, winding is stable, and high-speed winding is easily achieved.

Description

technical field [0001] The present invention relates to rewinders, in particular to rewinders for the production of coreless paper rolls. Background technique [0002] The coreless paper roll produced by the coreless paper roll rewinding machine is a paper roll without a core tube. The core of this paper roll is wound directly from the head of the paper. The winding principle of the existing coreless paper roll rewinding machine is to use the rubbing action of the roll surface of the rewinding upper roll in rotation to make the paper head wind around itself to form the core of the paper roll . This kind of winding method is difficult to make the core of the paper roll form a relatively regular circle, there are many moving parts that need to cooperate with each other, the control is difficult, the winding is not stable enough, and it is difficult to realize high-speed winding. Contents of the invention [0003] The purpose of the present invention is to provide a corele...
