Problems solved by technology

This kind of winding method needs to set pits on the roller surface of the rewinding upper roller to accommodate the newly formed core of the paper roll. Therefore, the rotation of the rewinding upper roller must be strictly controlled at the moment when the moving part is in contact with the roller surface. Angle, so that the pit groove on the roller surface just rotates to the position opposite to the friction surface of the moving part, which greatly increases the difficulty of control, will inevitably have strict requirements on processing technology, and increases the manufacturing cost of the rewinder and the difficulty of machine debugging

Embodiment 1

[0017] See figure 1 , A coreless paper rewinding machine according to the present invention includes an upper rewinding roll 1 and a lower rewinding roll 2. Below the upper rewinding roller 1 is provided a pressing member 3 for realizing a paper breaking action. During the paper break action, such as figure 2 As shown, the pressing member 3 rotates around the shaft 4, and the pressing member 3 touches the paper wound on the upper rewinding roller 1, so that the tail paper of the rewinding paper roll 5 is disconnected.

[0018] See figure 1 , Under the upper rewinding roller 1 is also provided a winding guide surface 6 close to the roller surface of the upper rewinding roller. See image 3 , The narrowest gap W between the unwinding guide surface 6 and the roller surface of the upper rewinding roller 1 is not more than 10 mm, and the paper travel direction is taken as the reference direction. The narrowest gap W is located at the contact pressure of the pressing member 3 on the p...

Embodiment 2

[0021] See Image 6 The difference between this embodiment and the first embodiment is that a plurality of suction ports 10 are added to the roll surface of the upper rewinding roll 1. These suction ports 10 can only take in air when rotated to the angle β. The effect is that the paper 7 is firmly adsorbed on the upper rewinding roller 1 within the range of the angle β, and the traction force of the upper rewinding roller 1 on the paper is enhanced. The other structure and unwinding process of this embodiment are the same as the first embodiment.

[0022] In the above embodiments, in order to avoid interference between the pressing member 3 and the winding guide surface 6, the winding guide surface 6 can be made Figure 7 In the comb-like structure shown, the winding guide surface is composed of a plurality of strip-shaped plates 6a arranged in parallel, and a gap 11 is left between each strip-shaped plate. when figure 2 The pressing member 3 shown turns to figure 2 In the pos...

Abstract

The invention discloses a coreless paper roll rewinder with reliable winding; a press piece used for cutting paper is arranged below a rewind upper roller; a winding guide surface close to the roller surface of the rewind upper roller is arranged below the rewind upper roller; the minimum gap between the winding guide surface and the roller surface of the rewind upper roller is not bigger than 10mm, and the gap is arranged on upstream of a press position of the press piece on the paper; the invention also discloses a coreless paper roll rewinder winding method: in beginning, the press piece and the minimum gap are matched to start winding of the paper; the coreless paper roll rewinder is reliable in winding, and the winding process needs not to strictly control a spin angle of the rewind upper roller, thus reducing technical process requirements, and reducing machine debug difficulty.

Description

Technical field [0001] The invention relates to a rewinder, especially a rewinder for producing coreless paper rolls. Background technique [0002] A coreless paper roll is a paper roll without a core tube. The core of the paper roll is directly wound from the head of the paper. In the existing coreless paper roll rewinder, the method of winding the paper head into the core of the paper roll is to use a moving part with a friction surface against the roll surface of the upper rewinding roll to make the paper head The moving part is rubbed between the friction surface and the roller surface to roll up. This type of unwinding requires a groove on the surface of the upper rewinding roll to accommodate the newly formed core of the paper roll. Therefore, when the moving part is in contact with the roll surface, the rotation of the upper rewinding roll must be strictly controlled. The angle makes the groove of the roller surface just rotate to the position opposite to the friction su...
