Scratch-proof protective film winding mechanism and slitting module

Abstract

The invention discloses a scratch-proof protective film winding mechanism and a slitting module. A bearing bracket, a limiting device, a winding device and a receiving device are included, wherein thelimiting device, the winding device and the receiving device are all arranged on the bearing bracket; the limiting device includes a first limiting component and a second limiting component, whereinthe first limiting component and the second limiting component are arranged on the bearing bracket; and the winding device comprises a winding frame and a plurality of winding components, the windingframe is arranged on the bearing bracket, and each winding component is arranged on the winding frame. The invention realizes automatic winding of protective films, can wind a plurality of protectivefilms at a time, improves the winding efficiency of the protective films, and facilitates winding; in addition, a winding paper tube is prevented from sliding left and right along a winding roller, the offset condition is ensured to be avoided during winding of the protective films, and the problem that the protective films on the paper tube are untidy is avoided; and meanwhile, the winding efficiency is improved, and the output of the protective films is improved.

Description

technical field [0001] The invention relates to the field of slitting machines, in particular to an anti-scratch protective film winding mechanism and a slitting module. Background technique [0002] The main feature of the slitting machine is that the magnetic powder clutch is used as a resistance device to output a DC voltage through system control to control the resistance generated by the magnetic powder clutch. The main advantage is that it is a passive device and can control less tension. Disadvantage: The speed cannot be high, and it is easy to cause high-speed friction of the magnetic powder during high-speed operation, resulting in high temperature, causing the magnetic powder clutch to heat up and shorten its life. A device for longitudinally cutting a coil of a certain width with a knife and cutting it into several narrower rolls. After it is installed in unit devices such as calenders, extruders, and gluing machines, it can complete continuous cutting, often wi...

However, the existing winding methods rely on manual winding one by one, which is inefficient, time-consuming and labor-intensive; moreover, the existing winding drum is prone to slippage during winding, which is also a problem. That is, when the protective film or self-adhesive tape is rewound and rotated, the rewound paper tube is easy to slide left and right along the rewinding drum, which makes the deviation occur when the protective film is rewound, so that the protective film reeled on the paper reel The irregularity of the film also reduces the efficiency of winding and reduces the output of protective film
