A double-roller deviation rectifying device for surface treatment metal film production

Abstract

This utility model discloses a double-roller correction device for surface treatment metal coating production. It employs a structure with several guide rollers, a correction plate, and telescopic components to achieve non-destructive and automatic correction of the protective film. Specifically, during use, the protective film moves on the guide rollers. When it tilts, the telescopic components on each guide roller apply the same elastic preload to the correction plate, causing the tilted plate to be pushed back to a position parallel to the protective film's conveying direction, thus achieving automatic correction and preventing further tilting of the protective film that could affect subsequent conveying and coating. The elastic force applied to the correction plate by the telescopic components is achieved through atmospheric pressure applied to the movable rod by the pressure difference between the internal cavity and the external environment. This force acts on the correction plate, which aligns with the extension trajectory of the protective film, ensuring sufficient and non-destructive contact with the side of the protective film and preventing its deviation.

Description

Technical Field

[0001] This utility model relates to the technical field of metal parts processing equipment, specifically a double-roller correction device for surface treatment metal coating production. Background Technology

[0002] In the production of metal parts, a protective film is applied to the surface through a coating process to protect the product. The protective film needs to be controlled in its conveying direction during unwinding and winding to prevent tilting, requiring correction during this process. However, existing correction devices used in metal part surface coating production cannot achieve sufficient contact with the protective film during correction, causing excessive localized stress and damage such as warping, which in turn affects subsequent coating applications. Utility Model Content

[0003] The purpose of this invention is to solve the problem that existing correction devices used in the production of metal surface coating treatment are prone to damaging the protective film during correction treatment, thus affecting the subsequent coating use, and to provide a double roller correction device for surface treatment metal coating production.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a double-roller alignment device for surface treatment metal coating production, comprising:

[0005] Several guide rollers are mounted on a bracket, and a connecting seat is provided on the side of the bracket facing the guide rollers. A protective film is wrapped around the guide rollers.

[0006] A correction plate is disposed at the end of the guide roller. The correction plate abuts against the side of the protective film, and several telescopic components are provided between the correction plate and the connecting seat.

[0007] As a further description of the above technical solution:

[0008] The correction plate is in close contact with the surface of the guide roller.

[0009] As a further description of the above technical solution:

[0010] The extension direction of the correction plate is the same as the winding trajectory of the protective film.

[0011] As a further description of the above technical solution:

[0012] Several of the telescopic components are arranged at intervals along the circumference of the guide roller in an arc trajectory.

[0013] As a further description of the above technical solution:

[0014] The telescopic assembly includes a sleeve and a movable rod. The movable rod is slidably and sealingly inserted into the inner cavity of the sleeve. The outer ends of the sleeve and the movable rod are respectively positioned on the connecting seat and the correction plate. An inner channel communicating with the inner cavity is provided in the connecting seat, and the inner channel is connected to an external air pressure regulating mechanism.

[0015] As a further description of the above technical solution:

[0016] An inner limiting ring is provided on the inner side of the sleeve, and the inner limiting ring is slidably sleeved in the limiting groove of the movable rod, with a sealing ring embedded in the limiting groove.

[0017] In summary, by adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art:

[0018] This utility model's correction device employs a structure of several guide rollers, a correction plate, and a telescopic assembly, enabling non-destructive and automatic correction of the protective film. Specifically, during use, the protective film moves on the guide rollers. When it tilts, the telescopic assembly on each guide roller applies the same elastic preload to the correction plate, pushing the tilted plate back to a position parallel to the protective film's conveying direction. This achieves automatic correction, preventing further tilting of the protective film and ensuring it doesn't affect subsequent conveying and lamination. The elastic force applied to the correction plate by the telescopic assembly is achieved through atmospheric pressure created by the pressure difference between the inner cavity and the external environment, acting on the movable rod. Since the correction plate's trajectory aligns with the protective film's extension path, it ensures sufficient and non-destructive contact with the film's sides, preventing deviation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Please see Figure 1-3 This utility model provides a technical solution: a double-roller correction device for surface treatment metal coating production, comprising:

[0028] A plurality of guide rollers 1 are mounted on a bracket 2. A connecting seat 3 is provided on the side of the bracket 2 facing the guide rollers 1. A protective film 100 is wound around the guide rollers 1. The guide rollers 1 can be mounted on the bracket 2 by a fixed connection or a rotating connection driven by a motor. The protective film 100 is moved by the traction of the winding and unwinding mechanisms at both ends (which are existing technologies and will not be described in detail here).

[0029] The correction plate 4 is arranged at the end of the guide roller 1. The correction plate 4 abuts against the side of the protective film 100, and several telescopic components 5 are arranged between it and the connecting seat 3.

[0030] The correction plate 4 is in close contact with the surface of the guide roller 1.

[0031] The extension direction of the correction plate 4 is the same as the winding trajectory of the protective film 100. Specifically, it can be adopted as follows: Figure 1 , 2 If there is a requirement for single-sided contact (one side is the rubber surface and cannot contact the guide roller 1), then the single-sided contact winding method shall be adopted.

[0032] Several of the telescopic components 5 are arranged at intervals along the circumference of the guide roller 1 in an arc trajectory.

[0033] The telescopic assembly 5 includes a sleeve 51 and a movable rod 52. The movable rod 52 is slidably and sealingly inserted into the inner cavity 53 of the sleeve 51. The outer ends of the sleeve 51 and the movable rod 52 are respectively positioned on the connecting seat 3 and the straightening plate 4. The connecting seat 3 is provided with an inner channel 31 communicating with the inner cavity 53. The inner channel 31 is connected to an external air pressure regulating mechanism (mainly used to inject air into the inner cavity 53 to form a certain and controllable pressure difference with the external environment; this is existing technology and will not be described in detail here). An inner limiting ring 54 is provided on the inner side of the sleeve 51. The inner limiting ring 54 is slidably sleeved in the limiting groove 55 of the movable rod 52. A sealing ring 56 is embedded in the limiting groove 55.

[0034] The working principle of the double-roller correction device for surface treatment metal coating production in this embodiment includes: During use, the protective film 100 moves on the guide roller 1. When it tilts, the telescopic components 5 on each guide roller 1 apply the same elastic preload to the correction plate 4, causing the tilted correction plate 4 to be pushed back to a position parallel to the conveying direction of the protective film 100, thus achieving automatic correction and preventing the protective film 100 from tilting further and affecting subsequent conveying and coating. The elastic force applied by the telescopic components 5 to the correction plate 4 is achieved by the atmospheric pressure applied to the movable rod 52 formed by the pressure difference between the inner cavity 53 and the external environment. This force acts on the correction plate 4, and the correction plate is consistent with the extension trajectory of the protective film, achieving full and non-destructive contact with the side of the protective film 100 and preventing its deviation. This design allows for adjustment of the elastic force to adapt to the non-destructive conveying requirements of protective films of different materials and sizes.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
