Description

Technical Field

[0001] This utility model relates to the field of coating technology, specifically a coating mechanism for the body of a steel bucket. Background Technology

[0002] The coating mechanism for steel bucket body plates is a device used to cover the surface of steel bucket body plates with a protective film (such as PVC, PET, PP, etc.). It is mainly used for rust prevention, corrosion prevention, aesthetics, or pretreatment for subsequent processing (such as printing, spraying).

[0003] Protecting the printed layer from damage or contamination is crucial to ensuring the quality of the final product when laminating steel drum plates after printing.

[0004] Before lamination, if the ink is not completely dry, the high temperature or pressure during lamination will cause the ink to soften and stick together. Undried ink may stick to the lamination material during the pressing process and transfer between different layers. After lamination, bubbles or pinholes will appear on the surface, affecting the appearance and protective performance. Therefore, there is a need to provide a method that can quickly prevent undried ink from entering the lamination process and improve the lamination quality. Utility Model Content

[0005] The purpose of this utility model is to provide a coating mechanism for the body of a steel bucket, so as to solve the problems mentioned in the background art. To solve the above technical problems, this utility model is achieved through the following technical solution: This utility model relates to a film-coating mechanism for the body of a steel bucket, comprising: A laminating machine and a steel plate, wherein the steel plate is placed on the upper surface of the laminating machine; The cleaning assembly includes a fixed frame, movable holes, movable columns, and baffles. The fixed frame is located at the inlet end of the laminating machine. There are eleven movable holes, which are equally spaced on the outer surface of the fixed frame. There are eleven movable columns, which slide through the corresponding movable holes. The baffles are fixed in the middle of the movable columns and are located in the middle of the fixed frame.

[0006] Furthermore, a controller is fixed to the middle of one side of the laminating machine, and a film roller is fixed to one side of the controller, with the film on the surface of the film roller covering the surface of the steel plate.

[0007] Furthermore, a spring is fixed to one side of the baffle, and the spring is located within the fixed frame.

[0008] Furthermore, a connecting frame is fixed to the lower surface of the movable column, and a rotating hole is provided inside the connecting frame.

[0009] Furthermore, a cleaning roller is installed inside the rotating hole, and the outer surface of the cleaning roller contacts the upper surface of the steel plate.

[0010] Furthermore, it also includes a drying assembly, which includes a drying frame and blowers. The drying frame is fixed to one side of a fixed frame, and the lower surface of the drying frame is fixedly connected to the upper surface of the laminating machine. There are three blowers, which are installed inside the drying frame.

[0011] Furthermore, the lower surface of the drying frame is provided with an installation groove, which is connected to the blower mounting hole, and three heating wires are fixed at equal intervals inside the installation groove.

[0012] This utility model has the following beneficial effects: This utility model relates to a laminating machine, controller, steel plate, film roller, and cleaning assembly. After printing on the steel plate, it enters the laminating machine. Before lamination, a fixed frame, under the elastic force of a spring, drives a baffle to move downwards, causing a movable column to move downwards. The movable column simultaneously drives a connecting frame to move downwards, bringing the cleaning roller inside the connecting frame into contact with the upper surface of the steel plate. This effectively absorbs the undried ink. The spring force automatically presses the cleaning roller together. Through rotation and adsorption, the cleaning roller transfers the undried ink from the steel plate surface to its own surface, preventing ink from entering the lamination process, reducing ink contamination, bubbles, and delamination risks, enhancing adhesion, and improving lamination quality.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 protection scope of the present utility model.

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0018] Please see Figure 1-4 As shown, this utility model is a film-coating mechanism for the body of a steel bucket, comprising: A laminating machine 11 and a steel plate 13 are placed on the upper surface of the laminating machine 11. A controller 12 is fixed in the middle of one side of the laminating machine 11, and a film roller 14 is fixed on one side of the controller 12. The film on the surface of the film roller 14 covers the surface of the steel plate 13. The laminating machine 11 is the core equipment used to laminate the film material onto the surface of the steel plate 13 by heating and pressurizing to achieve protection. The steel plate 13 is the substrate to be processed. The surface has been printed with patterns or text, and the laminating process is required to protect the printed layer and improve corrosion resistance. The controller 12 is the control system of the laminating machine 11, used to adjust the equipment parameters to ensure process stability. The film roller 14 carries the film material for lamination and releases the film material by rotating it to cover the surface of the steel plate 13.

[0019] The cleaning assembly includes a fixed frame 21, movable holes 22, movable columns 23, and baffles 24. The fixed frame 21 is located at the inlet end of the laminating machine 11. There are eleven movable holes 22, which are equally spaced on the outer surface of the fixed frame 21. There are eleven movable columns 23, which slide through the corresponding movable holes 22. The baffles 24 are fixed in the middle of the movable columns 23 and are located in the middle of the fixed frame 21. The fixed frame 21 provides stable guidance and clamping force for the cleaning roller 28, the movable hole 22 provides a guide channel for the movable column 23 to slide up and down, restricting its movement trajectory, the movable column 23 transmits the elastic force of the spring 25 to the connecting frame 26, driving the cleaning roller 28 to press down and contact the steel plate 13, and the baffle 24 connects the movable column 23 and the spring 25, and evenly transmits the elastic force of the spring to the movable column 23.

[0020] A spring 25 is fixed on one side of the baffle 24 and the spring 25 is located inside the fixed frame 21. A connecting frame 26 is fixed on the lower surface of the movable column 23. A rotating hole 27 is opened inside the connecting frame 26. A cleaning roller 28 is installed through the rotating hole 27. The outer surface of the cleaning roller 28 contacts the upper surface of the steel plate 13. Spring 25 provides a continuous downward elastic force, pushing the cleaning roller 28 to press against the steel plate 13, ensuring the ink adsorption effect. The connecting frame 26 fixes the cleaning roller 28 and converts the downward pressure of the movable column 23 into the pressing force of the cleaning roller 28 on the steel plate 13. The rotating hole 27 provides rotational support for the cleaning roller 28, reducing frictional resistance. The cleaning roller 28 directly contacts the surface of the steel plate 13 and adsorbs undried ink by rotation, preventing ink from entering the lamination process. Highly absorbent materials such as silica gel, felt, or sticky fibers are used to capture the ink.

[0021] Working principle: After printing on the steel plate 13, it will enter the laminating machine 11. Before lamination, it passes through the fixed frame 21. Under the elastic force of the spring 25, the spring 25 will drive the baffle 24 to move downward, causing the movable column 23 to move downward. The movable column 23 will simultaneously drive the connecting frame 26 to move downward, so that the cleaning roller 28 inside the connecting frame 26 contacts the upper surface of the steel plate 13 and absorbs the undried ink. The cleaning roller 28 is automatically pressed by the elastic force of the spring 25. The cleaning roller 28 transfers the undried ink on the surface of the steel plate 13 to its own surface through rotation and adsorption. This step prevents ink from entering the lamination process, reduces the risk of ink contamination, bubbles, and delamination, enhances adhesion, and improves lamination quality.

[0022] Please see Figure 1-4 As shown, this embodiment, based on the above embodiment, further includes: The drying assembly includes a drying frame 31 and a blower 32. The drying frame 31 is fixed to one side of the fixed frame 21, and the lower surface of the drying frame 31 is fixedly connected to the upper surface of the laminating machine 11. There are three blowers 32, which are installed inside the drying frame 31 respectively. The lower surface of the drying frame 31 is provided with an installation groove 33, which is interconnected with the installation holes of the blowers 32. Three heating wires 34 are fixed at equal intervals inside the installation groove 33. The drying frame 31 serves as the main frame of the drying assembly, used to fix the blower 32 and heating wire 34, and install them at the designated position of the laminating machine 11. The blower 32 generates forced airflow by rotating blades, blowing the air heated by the heating wire 34 onto the surface of the steel plate 13 to accelerate ink drying. The mounting groove 33 serves as the necessary path for hot air from the blower 32 to the steel plate 13, guiding the airflow to be evenly distributed. The heating wire 34 generates heat by passing current through it, heating the air blown out by the blower 32 to the set temperature.

[0023] Working principle: When the printed steel plate 13 is transferred to the laminating machine 11, the blower 32 is started by the controller 12 and the heating wire 34 is turned on. The heating wire 34 heats the air to the set temperature, and the blower 32 blows the hot air onto the surface of the steel plate 13. The hot air covers the printed layer of the steel plate 13, accelerates the evaporation of solvent in the ink, and dries the printed ink quickly. The three blowers 32 and the heating wire 34 work together to ensure that the surface of the steel plate 13 is heated evenly and avoids local overheating or insufficient drying. In this step, the hot air blown by the blower 32 and the heating wire 34 work together to accelerate the evaporation of the solvent in the ink, shorten the drying time, and prevent the ink from spreading due to friction or pressure during subsequent conveying or coating processes.
