Problems solved by technology

The existing rewinding control basically only controls the tapered tension of the rewinding. The pressure of the rewinding pressure roller is given by constant air pressure, and a constant pressure is always maintained. For some materials, when the diameter of the rewinding roll increases, the roll The material of the core not only needs to withstand the extrusion when the power is transmitted from the core to the outer layer of the receiving material during the center curling process, but also bears the extrusion of the constant pressure of the receiving pressure roller from the outer coil to the core, which is prone to internal and external coiling The deformation of the material is inconsistent, and the winding core is wrinkled (called winding core wrinkle). The winding effect cannot meet the technical requirements, which will bring many quality problems to the subsequent process.

Embodiment

[0040]The following four examples are used to describe the control conditions of different four composite materials. As shown in Table 1, four composite materials are selected, and the initial winding data of the four groups of composite materials are respectively set, and then the winding data of the four composite materials are set. The relational formulas (1), (2) and (3) of the roller pressure and the roll diameter can be obtained from their respective expressions, and the curves of the pressure of the receiving roller and the roll diameter corresponding to each group of materials can be obtained image 3 , Figure 4 , Figure 5 with Image 6 .

[0041] Table 1 sets the initial data for the four materials

[0042]

[0043]

[0044] by the curve image 3 , Figure 4 , Figure 5 with Image 6 It can be seen that the variation law and the function diagram of the four groups of embodiments figure 2 Basically match, therefore the pressure taper control system of ...

Abstract

The invention aims to provide a material winding double-taper control method. Taper pressure of a material winding pressing roller is controlled while taper tension is controlled during printing and composite material winding, the pressure of the material winding pressing roller is increased along with the winding diameter, the material winding taper tension and material winding pressing roller taper pressure can be simultaneously controlled through the control method with the pressure being gradually decreased in a tapered mode, and the winding quality of print materials is obviously improved.

Description

technical field [0001] The invention belongs to the technical field of printing and composite machinery, and in particular relates to a method for controlling double taper of receiving materials. Background technique [0002] In the entire printing and compounding process, the printed and compounded products are wound into rolls through the operation of the receiving shaft for use in subsequent processes. In this process, the rolling effect of the finished product is particularly important. In practical applications, the curling effect of post-press and composite products is usually controlled by controlling the tension of the receiving material. In the general crimping process, the tension needs to be reduced correspondingly with the increase of the coiling diameter, so as to prevent damage to the reel and the phenomenon of inner looseness and outer tightness during the winding process, which will also bring troubles and difficulties to the subsequent process. Therefore, ...
