Description

Technical Field

[0001] The utility model relates to the technical field of release paper production and rolling, in particular to a paper roll rolling device. Background Art

[0002] Release paper is actually a type of anti-adhesive paper, which is also called isolation paper, anti-adhesive paper, silicone oil paper, etc. Its main function is to prevent prepregs from sticking to each other. It is generally composed of three layers, the first layer is the base paper, the second layer is the coating, and the third layer is silicone oil. Release paper has been widely used in electronic products, automotive foam, medical and other fields, but in most cases, it is used together with sticky materials, such as adhesive tape, etc.

[0003] A Chinese patent with announcement number CN112357640B discloses a winding device for mica paper production. The technical problem to be solved by the present invention is that the existing mica paper winding device does not have a detection device, and cannot accurately determine how much mica paper is wound up, and does not have an automatic cutting function, which reduces the production efficiency of mica paper. In order to solve the above technical problems, the present invention provides a winding device for mica paper production. The present invention is composed of a detection mechanism and a shearing mechanism. The detection device can accurately determine whether the amount and thickness of the rolled mica paper meet the requirements. In conjunction with the single-chip microcomputer module, the winding work can be quickly ended after the winding is completed. Compared with the prior art, the present invention is more intelligent, and the thickness of the mica paper rolls produced is consistent; the detection height can be adjusted by pulling out two spring columns, which is more flexible; the excess mica paper can be sheared by the shearing mechanism. Compared with the prior art, the present invention can improve the production efficiency of mica paper to a certain extent.

[0004] However, the above technical solution has the following defects: the winding drum in the above-mentioned mica paper production winding device is installed on the third rotating shaft. The size of the winding drum may change according to different usage requirements, and the third rotating shaft cannot adapt and is inconvenient to use; after the paper is cut by scissors, the end of the paper is not fixed and will fall off, which is inconvenient for subsequent winding, thereby reducing the winding efficiency.
