Description

Technical Field

[0001] This utility model relates to the field of thin film preparation technology, specifically to a coating device for preparing EB film. Background Technology

[0002] EB is short for Electron Beam Curing, which can be applied to decorative films or boards. EB coating film is a composite film. After coating treatment, the relevant properties of EB film can be improved and its service life can be extended. Therefore, many EB films undergo coating treatment.

[0003] Coating equipment generally includes coating rollers and pressure rollers. EB film is transported between the coating rollers and pressure rollers to achieve the coating process. Currently, the equipment requires feeding the coating rollers after a certain period of time to ensure sufficient coating on the rollers. However, the current equipment generally requires stopping the machine when feeding the coating rollers, which undoubtedly delays the working efficiency of the equipment, reduces the processing speed of EB film, and cannot automatically and quickly feed the coating onto the coating rollers. Therefore, improvements are needed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a coating device for EB film preparation. By creating a cavity in the frame and installing a lifting mechanism at the cavity, the device controls the raising and lowering of the coating feeding mechanism. The coating feeding mechanism mainly consists of a coating box and a coating roller rotatably connected to the coating box. When the coating box moves upward, the coating roller contacts the coating roller, causing the coating roller to rotate. This rotation carries the coating out, thus achieving automatic feeding of the coating roller. This method enables automatic and rapid feeding of the coating roller without requiring machine downtime, solving the problems of unreasonable coating roller feeding methods and reduced work efficiency in current equipment.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0008] A coating apparatus for preparing EB film includes a frame and a coating roller rotatably connected to the frame. The frame has a cavity corresponding to the coating roller. The apparatus also includes a coating feeding mechanism, which is retractably disposed inside the cavity. The coating feeding mechanism includes a coating box and a coating roller rotatably connected to the upper part of the coating box. The coating box stores coating material, and the coating roller can carry the coating material out when it rotates. When the coating roller is in contact with the coating roller, the coating material can be fed onto the coating roller. A lifting mechanism is installed in the cavity of the frame to control the lifting of the coating feeding mechanism.

[0009] Furthermore, a scraper is fixedly connected to the upper part of the paint box on one side of the paint roller. The scraper is fixed to the inner side of the paint box along the length direction of the paint roller, and one side of the scraper has an arc-shaped surface that is connected to the outer contour of the paint roller.

[0010] Furthermore, the lifting mechanism includes: a bidirectional lead screw, which is laterally rotatably connected to the cavity of the frame; two sliders, which are symmetrically threaded onto the bidirectional lead screw, and both sides of the two sliders have protruding edges; a lifting plate, which is fixedly connected to the lower surface of the paint box; and a support arm, which is rotatably connected between the lower surface of the lifting plate and the corresponding protruding edge.

[0011] Furthermore, the lifting mechanism also includes a limiting rod fixedly connected to the frame, and the slider has a limiting hole adapted to the limiting rod at the corresponding position of the limiting rod.

[0012] Furthermore, one end of the bidirectional lead screw extends to the outside of the frame and is fixedly connected to a handwheel.

[0013] Furthermore, a mounting frame is fixedly connected to the upper surface of the frame above the coating roller, and a pressure roller is rotatably connected to the inner side of the mounting frame.

[0014] (III) Beneficial Effects

[0015] Compared with the prior art, this utility model provides a coating apparatus for EB film preparation, which has the following features:

[0016] Beneficial effects:

[0017] This invention utilizes a cavity groove created at the coating roller on the frame. A lifting mechanism is installed at the bottom of the inner side of the cavity groove, and a paint feeding mechanism is located at the top of the lifting mechanism. The lifting mechanism controls the raising and lowering of the paint feeding mechanism. The paint feeding mechanism includes a paint box and a paint roller rotatably connected to the upper part of the paint box. The paint box stores paint inside, and the paint roller carries the paint out when it rotates. When the lifting mechanism controls the paint box to move upward, and the paint roller contacts the coating roller, the coating roller rotates due to its own rotation. As the paint roller rotates, it carries the paint out, resulting in the paint being evenly coated onto the coating roller. This achieves automatic paint feeding to the coating roller. This feeding method is uniform, ensuring the coating preparation effect of the EB film. Furthermore, this feeding method does not require stopping the equipment, thus not delaying the equipment's working efficiency. It enables continuous and uninterrupted coating of the EB film, improving work efficiency. Attached Figure Description

[0023] 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.

[0024] Example

[0025] like Figure 1 , Figure 3 and Figure 4 As shown in the figure, an embodiment of the present invention provides a coating apparatus for preparing EB film, including a frame 1 and a coating roller 5 rotatably connected to the frame 1. The frame 1 has a cavity 2 corresponding to the coating roller 5. The apparatus also includes a coating material feeding mechanism 4, which is telescopically disposed inside the cavity 2. The coating material feeding mechanism 4 includes a coating material box 401 and a coating material roller 402 rotatably connected to the upper part of the coating material box 401. The coating material box 401 stores coating material. When the coating material roller 402 rotates, it can carry out the coating material. When the coating material roller 402 is in contact with the coating roller 5, the coating material feeding process of the coating roller 5 can be realized. A lifting mechanism 3 is installed in the cavity 2 of the frame 1 to realize the lifting control of the coating material feeding mechanism 4.

[0026] It should be noted that the coating roller 5 is used for coating EB film. A cavity 2 is opened at the location of the coating roller 5 on the frame 1. The cavity 2 is used for the installation of the lifting mechanism 3 and the paint feeding mechanism 4. The lifting mechanism 3 can control the lifting and lowering of the paint feeding mechanism 4 and adjust the height of the paint feeding mechanism 4. The paint feeding mechanism 4 can realize the paint feeding function of the coating roller 5, ensuring the coating effect of EB film. The paint feeding mechanism 4 is mainly composed of paint box 401 and paint roller 402. When the lifting mechanism 3 controls the paint box 401 to move upward, it can make the paint roller 402 contact the coating roller 5. When the coating roller 5 rotates, the paint roller 402 rotates along with it. During the rotation of the paint roller 402, the paint in the paint box 401 can be carried out, thereby realizing the uniform coating of the coating roller 5. This method can realize the automatic feeding of paint to the coating roller 5 without stopping the machine, thus ensuring the processing efficiency of EB film.

[0027] like Figure 3 As shown, in some embodiments, a scraper 403 is fixedly connected to the upper part of the paint box 401 on one side of the paint roller 402. The scraper 403 is fixed to the inner side of the paint box 401 along the length direction of the paint roller 402, and one side of the scraper 403 has an arc-shaped surface that is in contact with the outer contour of the paint roller 402.

[0028] It should be noted that the scraper 403 is designed to scrape off excess paint from the paint roller 402, preventing excessive paint from being carried out of the paint roller 402, which would lead to waste and uneven application. By setting an arc-shaped surface on one side of the scraper 403, and having the arc-shaped surface connected to the outer contour of the paint roller 402, the scraping distance can be extended through the arc-shaped surface, thereby increasing the scraping effect.

[0029] like Figure 1 and Figure 2 As shown, in some embodiments, the lifting mechanism 3 includes: a bidirectional lead screw 301, which is laterally rotatably connected to the cavity 2 of the frame 1; two sliders 302, which are symmetrically threaded onto the bidirectional lead screw 301, and both sides of the two sliders 302 are provided with protruding flanges 303; a lifting plate 305, which is fixedly connected to the lower surface of the paint box 401; and a support arm 304, which is rotatably connected between the lower surface of the lifting plate 305 and the corresponding flange 303.

[0030] It should be noted that by setting a bidirectional lead screw 301, the rotation of the bidirectional lead screw 301 can cause the two sliders 302 to move towards each other. By fixing the lifting plate 305 on the lower surface of the paint box 401, the paint box 401 is supported. By rotatably connecting the support arm 304 between the lower surface of the lifting plate 305 and the corresponding protrusion 303, when the slider 302 moves, the support arm 304 can be folded to achieve the supporting function of the lifting plate 305, thereby controlling the lifting of the lifting plate 305 and realizing the adjustment of the overall height of the paint feeding mechanism 4.

[0031] like Figure 2 As shown, in some embodiments, the lifting mechanism 3 further includes a limiting rod 306 fixedly connected to the frame 1, and the slider 302 has a limiting hole that is adapted to the limiting rod 306 at the corresponding position of the limiting rod 306.

[0032] It should be noted that the limiting rod 306 is designed to limit and guide the movement of the slider 302, thus ensuring the stable extension and retraction of the slider 302.

[0033] like Figure 1 and Figure 2 As shown, in some embodiments, one end of the bidirectional lead screw 301 extends to the outside of the frame 1 and is fixedly connected to a handwheel 307.

[0034] It should be noted that the handwheel 307 is configured to control the rotation of the bidirectional lead screw 301, which in turn controls the movement of the slider 302, thereby achieving the lifting control of the lifting plate 305 and adjusting the height of the paint feeding mechanism 4.

[0035] like Figure 1 As shown, in some embodiments, a mounting frame 7 is fixedly connected to the upper surface of the frame 1 above the coating roller 5, and a pressure roller 6 is rotatably connected to the inner side of the mounting frame 7.

[0036] It should be noted that the EB film is transported between the coating roller 5 and the pressure roller 6. The coating roller 5 is used to add the coating to the EB film.

[0037] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
