Problems solved by technology

This layout of the suction port brings the following problems: 1. Since there are many non-suction positions between the multiple suction ports arranged in a row along the axial direction, the adsorption force of the rewinding roller to the paper is between The paper is discontinuous in the width direction; 2. Affected by the first point above, the paper is prone to wrinkling due to uneven axial force during the process of being adsorbed and rolled, which affects the quality of the core of the paper roll; 3 , Affected by the above-mentioned first point, it is difficult for the rewinding roller to ensure the roundness of the paper head curl when it drives the paper head to curl, so that the rewinder often cannot produce paper roll products with high-quality cores; 4 . Since the shape of the single suction port is circular, and the aperture of the suction port cannot be opened too large, the adsorption force of the single suction port to the paper is small, and it is difficult to reliably absorb the paper with high density and hard texture. paper, resulting in low paper adaptability of the rewinder

Embodiment 1

[0019] see figure 1 , figure 1 It is an orthographic projection view of the cylindrical surface of the rewinding roller. The cylindrical surface 1 of the rewinding roller is provided with a plurality of slit-shaped suction ports 2, and every three slit-shaped suction ports 2 are arranged on the same generatrix of the cylindrical surface Above, the length direction of the slit-shaped suction port 2 is parallel to the axial direction of the rewinding roller. As a preferred embodiment, the length of each slit-shaped suction port 2 is not less than a quarter of the width of the paper adsorbed on the rewinding roller. exist figure 1 In the shown embodiment, the length L of each slit-shaped suction port 2 is approximately equal to one-third of the width of the paper adsorbed on the rewinding roller. The width W of each slit-shaped suction port 2 is preferably not greater than 4 millimeters.

Embodiment 2

[0021] see figure 2 , figure 2 Also an orthographic view of the cylindrical surface of the winding roll. This embodiment and figure 1 The difference is that there is only one slit-shaped suction port 2 on the same generatrix of the cylindrical surface of the rewinding roller, and the two ends of the slit-shaped suction port 2 are connected to the paper that is adsorbed on the rewinding roller. The distance between the edges is not greater than 100 mm. that is figure 2 The dimension S marked in is not greater than 100 mm ( figure 2 The dotted line in indicates the paper picked up by the rewind roller). Compared with Embodiment 1, this embodiment not only reduces the number of slit-shaped suction ports 2, simplifies the structure of the rewinding roller, but also makes the adsorption force of the rewinding roller to the paper more continuous in the width direction of the paper. For other structural features of this embodiment, reference may be made to Embodiment 1.

Abstract

The invention discloses a rewinding roll for a rewinding machine. A plurality of air suction ports are formed in the cylindrical surface of the rewinding roll; each air suction port is of a slit type, and the length direction of each slit type air suction port is in parallel with the axis direction of the rewinding roll. Compared with an existing rewinding roll with a circular air suction port, the rewinding roll has the advantages that 1, under the condition that the axial dimension of the rewinding roll is the same, non-suction positions among the air suction ports are reduced, and the adsorbing force of the rewinding roll on paper becomes more successive in the width direction of the paper; 2, the axial force applied on the paper being adsorbed and wound becomes more uniform, and the situation of crinkly paper end cannot appear easily; 3, the rewinding roll can easily guarantee the winding roundness of the end part of the paper while driving the end part of the paper for winding, and the rewinding machine can continuously produce paper roll products with high-quality cores; 4, the adsorbing force of a single air suction is greater, the rewinding roll can easily adsorb paper in higher density and harder texture and smoothly rewind the paper, and the paper adaptability of the rewinding machine is reinforced.

Description

technical field [0001] The present invention relates to a rewinding machine for reeling paper into rolls, in particular to a rewinding roller of a rewinding machine. 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 air-suction take-up mechanism. This type of rewinder is evenly distributed with suction ports that absorb paper on the cylindrical surface of its rewinding roller. . In the existing rewinding machine of this type, the suction ports on the cylindrical surface of the rewinding roller are arranged in multiple rows along the circumferential direction of the roll body, and each row of suction ports is composed of multiple suction ports along the roller body. The axial arrangement is formed, and the shape of a single suction port is circular. This layout of the suction port brings the following problems: 1. Since there are many non-suction positions between the multi...
