Description

Technical Field

[0001] This utility model relates to the field of elevator door panel manufacturing technology, specifically to an automatic film coating mechanism for belt-driven stainless steel composite elevator door panels. Background Technology

[0002] Elevator door panel coating is a technology used to protect the surface of elevator door panels during the elevator manufacturing process. It is mainly used to prevent scratches, collisions and contamination during transportation, installation or commissioning. Elevator door panel coating usually uses PE (polyethylene) film, PVC film or PET film, which has the characteristics of scratch resistance, wear resistance and stain resistance.

[0003] Although there are auxiliary lamination tools in the current elevator door panel lamination process, lamination is a delicate task. The operation is basically done manually with manual film cutting. The lamination production efficiency is low and the labor intensity is high. The film is uneven and has air bubbles. Moreover, manual film cutting is less safe and the lamination production is not smooth.

[0004] To improve automation, the existing lamination process needs to be automated to enable automated lamination of elevator door panels, thereby increasing lamination efficiency, reducing manual labor, and ensuring work safety. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by providing a belt-driven stainless steel composite elevator door panel automatic film-coating mechanism that further enhances automation, improves work efficiency, and reduces manual labor.

[0007] The belt conveyor assembly includes a loading belt, a working belt, and a unloading belt arranged in sequence, with joints between adjacent belts for conveying door panels;

[0008] The protective film assembly includes a protective film roller, which is positioned above the upstream of the working belt via a protective film roller frame for winding the protective film.

[0009] The fabric roller assembly includes a fabric roller, which is disposed downstream of the protective film roller via a fabric roller frame, for attaching the protective film to the door panel;

[0010] The brush roller assembly includes a brush roller, which is disposed downstream of the cloth roller via a brush roller frame, for pressing the protective film onto the door panel.

[0011] The film cutting assembly includes a cutter positioned downstream of the brush roller and directly opposite the seam between the working belt and the feed belt, for cutting the protective film.

[0012] Preferably, the feeding belt, working belt, and unloading belt each include two rows of parallel transmission belts that run synchronously at the same speed.

[0013] Preferably, the feeding belt, working belt, and unloading belt are all driven independently.

[0014] Preferably, the conveying speeds of the feeding belt, working belt, and unloading belt are the same or all different.

[0015] Preferably, there are two protective film rollers, both used for winding the protective film, and one of them can be used during operation.

[0016] Preferably, the cloth roller frame is a lifting bracket used to adjust the distance between the cloth roller and the door panel.

[0017] Preferably, the brush roller frame is a lifting bracket used to adjust the distance between the brush roller and the door panel.

[0018] Preferably, the film cutting assembly includes a cylinder and a cutter. The cylinder is mounted above the working belt via a bracket, and the cylinder drives the cutter to cut the protective film through a lifting action.

[0019] Preferably, the cylinder is a rodless cylinder.

[0020] Preferably, external supports are provided on both sides of the feeding belt, working belt and unloading belt.

[0021] This utility model has substantial features and progress compared to the prior art. Specifically, this utility model uses a conveyor belt to transport the door panel, and combines a protective film roller, a cloth roller, and a brush roller to achieve the coating, pressing, and air release of the protective film.

[0025] The technical solution of this utility model will be further described in detail below through specific embodiments.

[0026] like Figure 1 and Figure 2 As shown, an automatic film-coating mechanism for belt-driven stainless steel composite elevator door panels includes a belt conveyor assembly, a protective film assembly, a cloth roller assembly, a brush roller assembly, and a film-cutting assembly.

[0027] The belt conveyor assembly includes a loading belt 1, a working belt 2, and a unloading belt 3 arranged in sequence, with seams between adjacent belts for transporting door panels. In this embodiment, to meet the width requirements of the door panels, the loading belt 1, the working belt 2, and the unloading belt 3 each include two rows of parallel, synchronous, and speed-running transmission belts, which can fully support the elevator door panels and avoid the problem of unstable support caused by excessively wide elevator door panels.

[0028] Since the required transport speeds for the door panels are not entirely the same during the loading, lamination, and unloading processes, in this embodiment, the loading belt 1, working belt 2, and unloading belt 3 are all driven independently and can be flexibly adjusted according to the working parameters. The transport speeds of the loading belt, working belt, and unloading belt may be the same or different for all of them.

[0029] The protective film assembly includes a protective film roller 4, which is positioned above the upstream of the working belt 2 via a protective film roller frame 5 and is used to wind the protective film. In this embodiment, two protective film rollers 4 are arranged in parallel, and one can be used at a time. After a roll of protective film is used up, film can be quickly replenished, allowing sufficient time for clamping a new protective film.

[0030] The fabric roller assembly includes a fabric roller 6, which is located downstream of the protective film roller via a fabric roller frame 7 for attaching the protective film to the door panel. The fabric roller frame 7 is an adjustable support that can adjust the film covering height according to the specific dimensions of the door panel.

[0031] The brush roller assembly includes a brush roller 8, which is located downstream of the cloth roller via a brush roller frame 9. It is used to press the protective film onto the door panel. Its main function is to press the protective film stably onto the door panel and avoid the generation of air bubbles and tilting problems.

[0032] The film cutting assembly includes a cylinder 10 and a cutter 11. The cutter 11 is located downstream of the brush roller and directly opposite the seam between the working belt 2 and the feeding belt 3. It is used to cut the protective film. The cylinder 10 is a rodless cylinder and is mounted above the working belt via a bracket 12. The cylinder 10 drives the cutter to cut the protective film through a lifting action.

[0033] The feeding belt 1, working belt 2 and unloading belt 3 are provided with external brackets 13 on both sides for installing protective film roller frame 5, cloth roller frame 7, brush roller frame 9 and bracket 12.

[0034] Working principle explanation:

[0035] After the elevator door panels are placed and aligned one by one, they are placed on the feeding belt 1 and then fed one by one to the working belt 2. After reaching the working belt 2, as the working belt 2 advances, the door panel comes into contact with the cloth roller 6 and the friction drives the cloth roller 6 to rotate. At the same time, the protective film wrapped around the cloth roller 6 is affixed to the door panel. As it continues to move forward, the brush roller surface is usually a flexible structure, such as a brush. Through the sweeping and pressing of the brush, the protective film is pressed and smoothed a second time, avoiding air bubbles and skewing. Then it continues to move forward. After the entire panel is covered with film, the tail end of the door panel moves to the film cutting assembly. The cylinder 10 drives the cutter 11 to cut the protective film, completing the film application work of one door panel.

[0036] During this process, the operating frequency and cutting timing of the cylinder 10 can be calculated using the operating parameters of each belt. In a preferred embodiment, a corresponding sensor can also be added to detect the specific position of the door panel, and the protective film can be cut according to the sensor's detection information.

[0037] Finally, it should be noted that: the preferred embodiments of this patent have been described in detail above, but this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
