Surface film laminating device for plastic profile processing

Abstract

The invention discloses a surface film laminating device for plastic profile processing, which comprises a plurality of groups of film laminating mechanisms. A bottom plate is also provided with a plurality of groups of positioning mechanisms respectively matched with the plurality of groups of film laminating mechanisms, and the positioning mechanisms are used for fixing the position of a plastic profile placed on the bottom plate; a translation driving mechanism used for driving the sliding plates to slide on the bottom plate is further arranged on the bottom plate and comprises a plurality of groups of long grooves which are formed in the bottom plate in the sliding direction of the sliding plates and are located under the sliding plates in the multiple groups of film laminating mechanisms respectively, and conveying belts with the conveying direction parallel to the groove length direction are erected below the multiple groups of long grooves; a gear motor is arranged on the lower end face of the bottom plate and is in conveying connection with driving belt wheels of the multiple groups of conveying belts through a conveying shaft. Clutch mechanisms which penetrate through the long grooves and are connected and disconnected with the upper conveying face and the lower conveying face of the conveying belt correspondingly are arranged on the lower end faces of the sliding plates in the multiple groups of film laminating mechanisms. The situation of excessive unwinding of the unwinding wheel due to movement inertia can be prevented.

Description

technical field [0001] The invention relates to a film coating device, in particular to a surface film coating device for processing plastic profiles. Background technique [0002] With the rapid development of modern industry, plastic products can be seen everywhere in our life, and the demand for various profile products is gradually increasing. Profile extrusion production line is a special equipment for producing plastic profile products. The production line of this type The market demand has also increased. The surface of the profile is easily scratched during transportation, assembly or installation. Generally, a protective film is attached to the surface of the profile. [0003] The existing lamination processing equipment has the following defects: the unwinding wheel wound with film material is prone to excessive unwinding due to motion inertia when unwinding is not needed, so that the film material has no tension, thus Wrinkles are formed after it is covered on th...
