Plastic film applicator with a braking function

Abstract

A plastic film applicator includes an applicator body including a mandrel and a grip connected to the mandrel, and a brake device including a bearing ring detachably mounted between the mandrel and grip of the applicator body for enabling the elastic braking pad to be biased toward the applicator body by an external force and an elastic braking pad having one end thereof connected to the bearing ring and elastically biasable by an external force. After the user attached a plastic film roll onto the mandrel of the applicator body, the user can press the thumb on the elastic braking pad to timely force the elastic braking pad toward the plastic film roll, forcing the abutment protrusion of the elastic braking pad into abutment against the film roll shaft, and thus, a braking effect is provided to the film roll shaft to stretch the extended plastic film for wrapping.

Description

BACKGROUND OF THE INVENTION1. Field of the Invention[0001]The present invention relates to plastic film application technology, and more particularly to a plastic film applicator with a braking function.2. Description of the Related Art[0002]When using a plastic film roll for wrapping goods, the plastic film must be stretched to produce a certain tension so that the plastic film can be positively wrapped about the goods. According to conventional techniques, the user needs to give a certain contact force to the plastic film of the plastic film roll to provide a certain brake effect, keeping the extended plastic film in a stretched status for wrapping. But for the user, due to standing posture, it is inconvenient to brake the plastic film roll directly with the hand in the actual operation, and the tension of the extended plastic film can be insufficient, affecting the wrapping.SUMMARY OF THE INVENTION[0003]The present invention has been accomplished under the circumstances in view. ...

AI Technical Summary

Benefits of technology

[0003]The present invention has been accomplished under the circumstances in view. It is the main object of the present invention to provide a plastic film applicator for the application of a plastic film roll, which provides a braking function to enhance application convenience.

[0004]To achieve this and other objects of the present invention, a plastic film applicator comprises an applicator body and a brake device. The applicator body comprises a mandrel, and a grip connected to one end of the mandrel. The brake device comprises a bearing ring and an elastic braking pad. The bearing ring is detachably mounted between the mandrel and grip of the applicator body for enabling the elastic braking pad to be biased toward the applicator body by an external force.

[0005]Thus, after the user attached a plastic film roll onto the mandrel of the applicator body into abutment at the bearing ring of the brake device, the user can hold the grip of the applicator body for allowing the plastic film roll to be rotated relative to the applicator body so that the plastic film of the plastic film roll can be extended out for wrapping. During wrapping, the user can press the thumb on the elastic braking pad to timely force the elastic braking pad toward the plastic film roll, forcing the abutment protrusion of the elastic braking pad into abutment against the film roll shaft, and thus, a braking effect is provided to the film roll shaft to stretch the extended plastic film for wrapping.

Problems solved by technology

But for the user, due to standing posture, it is inconvenient to brake the plastic film roll directly with the hand in the actual operation, and the tension of the extended plastic film can be insufficient, affecting the wrapping.
