Problems solved by technology

However, in the existing rewinding machines of this type, the rewinding upper roller only has a corner range for controlling the negative pressure state of the suction port, and the adsorption effect of the suction port on paper within this corner range is only suitable for use without The winding process of core paper rolls (that is, paper rolls without a core tube in the middle) has no effect on the winding process of core paper rolls, or even harmful
In a nutshell, the suction-type winding mechanism used in existing rewinders only has a single function for coreless paper rolls

Embodiment 1

[0014] see figure 1 , the rewinder shown in the figure is in the state of producing coreless paper rolls. The rewinding machine includes a rewinding upper roll 1 and a rewinding lower roll 2 parallel to each other. A plurality of suction ports 3 are arranged on the cylindrical surface of the rewinding upper roller 1, and the plurality of suction ports 3 are divided into multiple groups along the circumferential direction of the rewinding upper roller 1, and each group of suction ports 3 is arranged along the roller The length direction of the body is arranged in a row. In the roll body of the rewinding upper roll 1, there are many air flow channels 4 separated from each other, and the multiple air flow channels 4 are arranged at intervals along the circumferential direction of the roll body. The suction ports 3 communicate correspondingly, and each airflow channel 4 penetrates to the end surface of the roller body and forms a port.

Embodiment 2

[0025] see Figure 7 , Figure 7 The winder is shown in condition to produce cored rolls. In fact, Figure 7 and figure 1 The rewinder shown is the same piece of equipment, Figure 7 with figure 1 The same numbers in the figure 1 State shown is for production of coreless paper rolls, figure 1 The roll gap M between the rewinding upper roll 1 and the rewinding lower roll 2 in the Figure 7 State shown is for production of cored paper rolls, Figure 7 The roll gap between the rewinding upper roll 1 and the rewinding lower roll 2 should be adjusted so that a core tube 11 can pass through, and a curved surface 12 is added, and the curved surface 12 is formed together with the cylindrical surface of the rewinding upper roll 1 A core tube channel 13 for guiding the core tube 11 into the nip between the rewinding upper roll 1 and the rewinding lower roll 2 .

Abstract

The invention discloses a re-reeling machine with a dual-functional adsorption type reeling mechanism. The re-reeling machine is characterized in that a roller body of a re-reeling upper roller is provided with multiple airflow passages, each airflow passage penetrates to the end surface of the roller body, at least two air suction cavities which are mutually separated are arranged in a position which is close to the end surface of the re-reeling upper roller, end openings, which are formed in the end surface of the roller body, of the airflow passages sequentially pass through a range covered by the air suction cavities along with the rotation of the re-reeling upper roller, a central angle covered by one air suction cavity on the end surface of the roller body is positioned within a corner range of a reeling process of a coreless paper roll of the re-reeling upper roller, and a central angle covered by the other air suction cavity on the end surface of the roller body is positioned within a corner range of the reeling process of a core paper roll of the re-reeling upper roller. The re-reeling machine disclosed by the invention has the advantages that the reeling process of the coreless paper roll can be realized, and the reeling quality of the core paper roll can be increased; on the other hand, since the two air suction cavities are separated, negative pressure generated by a vacuum pumping device is facilitated to be totally concentrated in a needed region, the waste of negative pressure power is reduced, and an energy-saving effect is obtained.

Description

technical field [0001] The present invention relates to rewinding machines for winding paper into rolls. Background technique [0002] Among the rewinders that produce paper roll products such as toilet paper rolls, there is a type of rewinder that uses an adsorption-type winding mechanism. This type of rewinder is evenly distributed with suction ports that absorb paper on the cylindrical surface of its rewinding upper roll. , during the winding process, the winding is realized by using the adsorption effect on the paper generated by these suction ports when they pass through a certain corner range of the rewinding upper roller. However, in the existing rewinding machines of this type, the rewinding upper roller only has a corner range for controlling the negative pressure state of the suction port, and the adsorption effect of the suction port on paper within this corner range is only suitable for use without The winding process of the core paper roll (that is, the paper r...
