Film roll locating device for surface film pasting of plastic product

Abstract

The invention relates to a film roll locating device for surface film pasting of a plastic product. The film roll locating device comprises locating racks located on the two sides, and a rotary shaftrotationally arranged on the locating racks in the axial lead directions of the rotary shafts through bearings correspondingly; the rotary shaft is broken from the middle part, thus a first rotary shaft body and a second rotary shaft body are formed; the first rotary shaft body and the second rotary shaft body are movably arranged on the locating racks on the two sides in a relatively drawn closeor getting far away manner; and the two ends of a film roll sleeve the inner ends of the first rotary shaft body and the second rotary shaft body correspondingly. The film roll locating device furthercomprises locating pieces which are movably arranged on the first rotary shaft body and the second rotary shaft body correspondingly and can abut against the two ends of the film roll. The film rollcan be replaced conveniently. Furthermore, the film roll can be transversely adjusted in the axial direction to meet different working requirements. In addition, the film roll locating device is simple in structure, convenient to implement and low in cost.

Description

technical field [0001] The invention relates to the field of unwinding auxiliary equipment for film rolls, in particular to a film roll positioning device for sticking films on the surface of plastic products. Background technique [0002] At present, the film sticking of various products is becoming more and more popular (such as mobile phones, routers), but it is very troublesome to stick film on small plastic products, because most of the manufacturers stick the film manually. However, regardless of manual film application or later automatic film application, the positioning of the film roll is necessary, and the current positioning method uses a positioning frame, a rotating shaft, and then the film roll is set on the rotating shaft, and the rotating shaft passes through bearings and The bearing seat is connected to the positioning frame. When the unwinding film is pulled, the film roll and the rotating shaft rotate together, and the film is gradually unrolled under the ...

AI Technical Summary

Problems solved by technology

[0004] 1. After a film roll is used, it is necessary to remove the rotating shaft and bearing, and then install a new film roll again to continue the unwinding work, so it is very inconvenient to replace;

[0005] 2. Once the replaced film roll has a position deviation or the corresponding position of the product changes, it cannot be adjusted adaptively, resulting in the inability to carry out the film sticking work
