Description

Rewinding machine convenient to switch between cored and coreless working modes

Technical Field

The utility model relates to equipment for producing paper rolls, in particular to a rewinding machine for rewinding paper into the paper rolls.

Background

Rewinding machines for producing paper rolls are provided with upper rewinding rolls and lower rewinding rolls. The rewinding machine operates in cored mode when it is necessary to wind paper on a core to make rolls with cores. When it is desired to wind paper into a coreless roll without a core tube, the rewinder operates in a coreless mode.

In the core mode, the roller gap between the upper rewinding roller and the lower rewinding roller is large, and when a new paper roll is rewound, the core tubes of the paper roll are conveyed to the roller gap between the upper rewinding roller and the lower rewinding roller by the conveying mechanism. In the coreless mode, the upper rewinding roller and the lower rewinding roller are close to each other, and a roller gap between the upper rewinding roller and the lower rewinding roller is small. The conveying mechanism of the conveying core pipe is useless in a coreless mode, and can prevent the upper rewinding roller and the lower rewinding roller from approaching. Therefore, the conventional rewinding machine needs to remove the conveying mechanism for conveying the core tube when the core mode is switched to the coreless mode, and otherwise needs to reinstall the conveying mechanism for conveying the core tube when the coreless mode is switched to the core mode, which is very inconvenient.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a rewinding machine which is convenient to switch between a cored working mode and a coreless working mode.

The utility model is realized by the following steps: the rewinding machine convenient for switching the working modes of the core and the coreless comprises an upper rewinding roller, a lower rewinding roller and a conveying mechanism for conveying the core tube of the paper roll to a roller gap between the upper rewinding roller and the lower rewinding roller, and particularly, the rewinding machine is further provided with a moving mechanism, the moving mechanism is connected with the conveying mechanism or at least the feeding tail end of the conveying mechanism, and the moving mechanism drives the conveying mechanism or at least the feeding tail end of the conveying mechanism to be close to or far away from the roller gap.

As a preferred embodiment, the moving mechanism includes a sliding member and a driving mechanism connected to the sliding member, the driving mechanism drives the sliding member to reciprocate, and the conveying mechanism or at least the feeding end of the conveying mechanism is connected to the sliding member.

In a preferred embodiment, the drive mechanism is a rack and pinion mechanism.

In a preferred embodiment, the conveying mechanism comprises a conveying belt for driving the core tube of the paper roll to advance towards the roller gap, the conveying belt is wound on a belt wheel, the belt wheel at the feeding end of the conveying belt is connected with the moving mechanism, and the moving mechanism drives the belt wheel to be close to or far away from the roller gap.

The utility model has the advantages that: when the rewinding machine works in a core mode, the moving mechanism drives the conveying mechanism or at least the feeding tail end of the conveying mechanism is close to a roller gap between the upper rewinding roller and the lower rewinding roller, so that the conveying mechanism can feed the core tubes of the paper rolls into the roller gap; when the core-free mode needs to be switched, the conveying mechanism or at least the conveying end of the conveying mechanism is driven by the moving mechanism to be far away from a roll gap between the upper rewinding roller and the lower rewinding roller, so that the conveying mechanism is prevented from blocking the upper rewinding roller and the lower rewinding roller to be close. Therefore, the rewinder can be conveniently switched between the core working mode and the coreless working mode without repeatedly installing and dismantling the conveying mechanism for conveying the core tubes.

Detailed Description

To facilitate an understanding of the utility model, the utility model is described more fully below with reference to the accompanying drawings. Preferred embodiments of the present invention are shown in the drawings. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. These embodiments are provided so that this disclosure will be thorough and complete.

It will be understood that when an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Referring to fig. 1, the rewinding machine facilitating switching between the cored and coreless operating modes includes an upper rewinding roller 1, a lower rewinding roller 2, and a conveying mechanism for conveying core tubes. The core tubes of the paper rolls are conveyed to a roller gap 3 between the upper rewinding roller 1 and the lower rewinding roller 2 one by the conveying mechanism. The transport mechanism of this embodiment comprises a conveyor belt 4 which carries the core of the paper roll towards the nip 3, the conveyor belt 4 being wound on a plurality of pulleys 5. More specifically, the conveyor belt 4 may be a chain, a timing belt or a belt, and accordingly, the pulley 5 may be a sprocket, a timing pulley or a pulley, or the like. The conveyer belt 4 is provided with stoppers 6 arranged at certain intervals to play a role of supporting and supporting the core tube 7.

The belt wheel 5a at the feed end of the conveyor belt 4 is connected to a moving mechanism. The moving mechanism comprises a sliding part 8, and the sliding part 8 is connected with the rack of the rewinding machine in a sliding mode through a guide rail 9. Two guide rails 9 are fixed on two sides of the frame. A pulley 5a at the feed end of the conveyor belt 4 is connected to the slide 8. The pulley 5a is moved by the slider 8 toward or away from the nip 3, so that the feed end of the conveyor belt 4 is moved toward or away from the nip 3. Alternatively, it is also possible that a plurality of pulleys of the conveyor belt 4 are connected to the slide 8, or that all the pulleys 5 of the conveyor belt 4 are connected to the slide 8, the entire conveyor belt 4 moving together with the slide 8. Fig. 1 is a schematic view of the rewinding machine in the cored operating mode. In the cored working mode, the sliding part 8 drives the belt wheel 5a to move to the position closest to the roller gap 3, the feeding end of the conveying belt 4 also reaches the position closest to the roller gap 3, at the moment, the conveying belt 4 can convey the core tubes 3 required by winding one by one, and the core tubes 3 roll to the roller gap 3 between the upper rewinding roller 1 and the lower rewinding roller 2 along a curved surface 12 arranged on the sliding part 8. Figure 2 is a schematic view of the rewinding machine in a coreless mode of operation. Under the coreless working mode, the sliding piece 8 drives the belt wheel 5a to be far away from the roller gap 3, the feeding tail end of the conveying belt 4 and the curved surface 12 are also far away from the roller gap 3, so that the upper rewinding roller 1 and the lower rewinding roller 2 can be close to each other, and the roller gap 3 is reduced.

The sliding part 8 is connected with a driving mechanism, and the driving mechanism drives the sliding part 8 to reciprocate. The drive mechanism of the present embodiment is a rack and pinion mechanism. Wherein, the rack 10 is fixed on the frame of the rewinding machine, and the gear 11 is arranged on the sliding piece 8. When the sliding part 8 needs to be moved, the gear 11 is driven by the motor to rotate, and the gear 11 rolls along the rack 10, so that the sliding part 8 is driven to reciprocate. As an equivalent variant, it is also possible that the rack 10 is fixed to the slide 8 and the pinion 11 is mounted on the frame and driven in rotation by a motor. In addition to the rack-and-pinion mechanism, the driving mechanism for driving the sliding member 8 to reciprocate may be a driving mechanism such as a cylinder or a hydraulic cylinder.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit and scope of the utility model. The protection scope of the present invention should be subject to the appended claims.
