Tearing-assistant device for elevator protection film

Abstract

The invention provides a tearing-assistant device for an elevator protection film. The tearing-assistant device comprises a rack body, a storage battery, an electric heating knife, a control panel, aheating mechanism, a regulation handle, a paper collection roller, a scraper blade and a top plate. According to the tearing-assistant device provided by the invention, the electric heating knife canbe arranged to cut off the protection film with a large area; since the electric heating knife does not need to be cut off by very large acting force, the scratching of the metal material part of an elevator can be effectively avoided, and the appearance of the elevator can be effectively prevented from being scratched; the heating mechanism is arranged to facilitate the tearing of the protectionfilm, a phenomenon of breaking or fracture during tearing can be avoided, the protection film is enabled to be torn down at one time, and the tearing efficiency of the protection film is improved; theregulation handle is arranged, the operation is simple, and different heights and positions and requirements of different people can be met; the paper collection roller and the scraper blade are arranged to avoid a fracture situation during tearing, and the paper collection roller and the scraper blade are used for tearing down the protection film so as to be favorable for avoiding a situation that the protection film is stuck to all places since the inner layer of the protection film is stuck with adhesive.

Description

technical field [0001] The invention belongs to the technical field of protective film tearing auxiliary devices, and in particular relates to an elevator protective film tearing auxiliary device. Background technique [0002] The metal base surface of the metal substrate has a protective film to protect the metal base surface from being scratched or corroded by liquid medicine during the production process. Therefore, the protective film needs to be removed before using the metal substrate. The current protective film mainly There are many problems with manual tearing of the film. First, the manual tearing of the film is labor-intensive, which causes the staff to be prone to fatigue; The yield rate is high, and manual tearing of the film can easily lead to problems such as line surface, surface misalignment, rubbing, or board corner warping. [0003] The Chinese patent publication number is CN 203995003 U, and the name of the invention is a metal substrate protective film ...

AI Technical Summary

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides an elevator protective film tearing auxiliary device to solve the problem that the existing metal substrate protective film tearing fixture cannot be torn off the protective film with a large area inside the elevator, which is inconvenient. Operation, the protective film cannot be torn apart, there is no structure to soften the inner glue of the protective film, and the operating handle cannot be adjusted, which is not conducive to the user's adjustment when tearing off the protective film according to different heights or different positions
