Embodiment 1

[0058] see image 3 According to a rewinding machine provided by the present invention, it comprises a rewinding upper roll 1, a rewinding bottom roll 2 and a paper pressing roll 3, the three of which jointly rotate with a paper roll 4, and the cylindrical surface of the rewinding upper roll 1 and A fixed curved surface 5 approaches each other to form a core tube channel 6 . The curved surface 5 in this embodiment is the top surface of a bracket 9, and the bracket 9 is fixedly connected with the frame of the rewinder. A core tube damping mechanism is provided at the entrance of the core tube channel 6 . The core tube damping mechanism of the present embodiment is a shift fork 10 arranged at the entrance of the core tube passage 6, such as Figure 4 As shown, when the second core tube 7 is just pressed against the rewinding upper roll 1, the shift fork 10 presses against the second core tube 7. Under the top pressure of the shift fork 10, although the second core tube 7 has ...

Embodiment 2

[0069] see Figure 11 , the main difference between this embodiment and Embodiment 1 is that the core tube damping mechanism arranged at the entrance of the core tube channel 6 is the core tube pressing claw 23, and the core tube 7 of the paper roll enters the core tube channel 6 and is just pressed on When rewinding upper roll 1, that is, at Figure 12 In the state shown, the core tube pressing pawl 23 presses on the core tube 7 from the rear and upper part of the advancing direction of the core tube 7, thereby preventing the rewinding upper roller 1 from driving the core tube 7 to roll. The core tube pressing claw 23 is fixed on a rotating shaft 24, and the rotating shaft 24 drives the core tube pressing claw 23 to rotate. Figure 11 and Figure 12 in and image 3 The same reference numerals denote the same components.

[0070] see Figure 13 The core tube pressing claw 23 is provided with a rough surface 25 at the part that is in contact with the core tube 7 , and the ...

Abstract

The invention discloses a paper breaking and rewinding method for a rewinder. Its main feature is that when the core tube is just pressed against the rewinding upper roll, the rewinding upper roll is prevented from driving the core tube to roll, so that the paper The paper at the end of the roll is stretched and broken. After the paper is broken, the barrier is removed, so that the paper head formed after the paper is broken is wound on the rolling core tube to form a new paper roll. The invention also discloses a rewinder capable of realizing the above method. The rewinder is provided with a core tube damping mechanism at the entrance of the core tube channel. The advantage of the present invention is that only after the paper at the tail of the paper roll is broken, the core tube pressed against the rewinding upper roller can roll along the core tube channel, thereby ensuring that the paper at the tail of the paper roll can be reliably broken, and at the same time It avoids the uneven stress on the paper at the end of the paper roll caused by the rolling of the core tube, and the paper breaks are neat.

Description

technical field [0001] The present invention relates to a rewinding machine for producing paper rolls with a core tube, in particular to the mechanism for breaking and rewinding in such a rewinding machine. Background technique [0002] A rewinder for producing paper rolls with a core tube, such as a rewinder for producing toilet paper rolls with a core tube, uses a paper breaking and winding mechanism such as figure 1 As shown, it includes a rewinding upper roller 1, a rewinding bottom roller 2 and a paper pressing roller 3, the three of which jointly rotate with a paper roll 4, and the cylindrical surface of the rewinding upper roller 1 and a fixed curved surface 5 are close to each other to form a Core tube channel 6. The basic working principle of this mechanism to realize paper breaking and rolling is: after the diameter of the current rewinding paper roll 4 meets the requirements, the core tube 7 of the new paper roll is sent into the core tube channel 6, when the cor...
