Online film coating device of elevator hall door plate

Abstract

The invention relates to an online film coating device of an elevator hall door plate. The online film coating device comprises a machine frame, wherein a power roller used for conveying an elevator hall door plate and a film storing mechanism used for providing a protective film are mounted on the machine frame, and the online film coating device further comprises an intercepting mechanism, a film clamping mechanism and a film cutting mechanism which are installed on the machine frame, wherein the intercepting mechanism is provided with a first blocking piece and a second blocking piece whichcan ascend and descend and are used for intercepting or releasing a front elevator hall door plate and a rear elevator hall door plate respectively so as to keep the distance between the front elevator hall door plate and the rear elevator hall door plate; the film clamping mechanism is provided with an upper clamping plate and a lower clamping plate which can ascend and descend respectively andare matched with each other, and is used for clamping the protective film to cater to the elevator hall door plate needing film coating or lifting the protective film to avoid the elevator hall door plate without film coating; and the film cutting mechanism is provided with an electric heating cutting wire which can ascend and descend and is used for cutting off the protective film at a preset position. By means of the arrangement, the online film coating device of the elevator hall door plate 12 can conduct targeted film coating on elevator hall door plates made of different materials, and itis guaranteed that the film lengths reserved at the front ends and the rear ends of the elevator hall door plates after film coating meet the standard.

Description

technical field [0001] The present application relates to the field of elevator manufacturing, in particular to an online coating device for elevator hall door panels. Background technique [0002] The commonly used materials for elevator hall door panels are usually Q235A material sheet metal. The outer surface of the hall door panel formed by sheet metal of this material needs to be covered with a protective film after powder spraying, while the rest of the hall door panels made of stainless steel do not need to be covered with a protective film, such as hall door panels made of SUS443 and SUS304. At the same time, for the hall door panel made of Q235A, due to the subsequent rivetless connection process, the mold length of the head and tail of the hall door panel after filming should not be too long, so as not to cause riveting or riveting through the rivetless connection process. In the order mode production in the form of an assembly line, each production order is diffe...

AI Technical Summary

Problems solved by technology

[0004] (1) Manual continuous online detection is used, which is labor-intensive; at the same time, during long-term detection, the detection personnel are prone to fatigue, and the production efficiency is greatly affected by manual work

[0005] (2) It is difficult to accurately control the length of the film at the head and tail of the hall door panel by manual coating, which can easily have a negative impact on the subsequent riveted connection process, affect product quality, and damage the riveted connection device

[0006] (3) Manual inspection requires a large amount of manpower, resulting in high inspection costs and high production pressure for enterprises

[0008] (1) It is difficult to accurately control the length of the film at the head and tail of the hall door panel by manual coating, which can easily have a negative impact on the subsequent riveted connection process, affect product quality, and damage the riveted connection device

[0009] (2) Since the hall door panel is bent on four sides, the rigidity of the middle part of the hall door panel is weak, and the coating film is prone to produce large air bubbles, which affects the aesthetics of the coating film and easily causes the film to fall off
