Description

Technical Field

[0001] This utility model relates to the technical field of coating machines, and in particular to a three-in-one flat plate coating test machine combining wire bar, doctor blade, and slit. Background Technology

[0002] Coating machines are essential industrial equipment widely used in surface coating processes for various materials such as films, paper, and fabrics. They are primarily used to coat rolls of substrates (such as paper, fabrics, leather, aluminum foil, and plastic films) with a specific functional adhesive, coating, or ink, followed by drying and then cutting into sheets or rewinding. Employing specialized multi-functional coating heads, they can achieve various surface coating methods, making them a key piece of equipment in film and paper surface coating processes. Coating machines are classified in various ways, such as by coating method (brush, air knife, doctor blade, roller, spray, curtain, slot canister, etc.). As a crucial piece of equipment in modern industry, coating machines play a vital role in multiple fields. However, traditional coating machines have a relatively simple operating mode and cannot simultaneously meet the requirements of different coating methods. Using different coating methods necessitates the use of multiple different models of coating machines, resulting in high costs. Utility Model Content

[0003] In order to enable a single coating machine to meet multiple coating methods, this utility model provides a three-in-one flat plate coating test machine combining wire bar, doctor blade, and slit coating, which addresses the problems of the prior art.

[0004] This utility model provides a three-in-one flat plate coating testing machine combining wire bar, doctor blade, and slit, which adopts the following technical solution:

[0005] A three-in-one flat plate coating testing machine combining wire bar, doctor blade, and slit head includes a base, a frame slidably mounted on the base, and a base fixedly mounted on the base. The frame is equipped with a wire bar, a doctor blade, and a slit head for coating. The wire bar, doctor blade, and slit head are located above the base. A lower crossbeam is provided on the frame.

[0006] Furthermore, the lifting assembly includes a lifting rod mounted on the frame, a cylindrical base fixedly mounted on the frame, a lifting seat mounted on the cylindrical base, and a handle mounted on the lifting seat. One end of the lifting rod is fixedly connected to the lower crossbeam, and the lifting rod movably passes through the cylindrical base. One end of the lifting seat is rotatably connected to the side wall of the cylindrical base, and the other end of the cylindrical base is rotatably connected to the side wall of the handle. The handle is provided with an extension, and the end of the extension away from the handle is rotatably connected to the side wall of the lifting rod away from the lower crossbeam.

[0007] Furthermore, a micrometer is provided on the lower crossbeam, a connecting block is movably provided on the frame, the scraper and the slit die head are fixedly provided on the connecting block, and the micrometer screw is fixedly connected to the connecting block.

They are only for the convenience of describing this application 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, and therefore should not be construed as a limitation on this application. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] This utility model discloses a three-in-one flat plate coating testing machine combining wire bar, doctor blade, and slit, such as... Figure 1-8 As shown, it includes a base 1, a frame 2 slidably mounted on the base 1, and a base 3 fixedly mounted on the base 1. Two guide rails 14 are fixedly installed on the base 1, and sliders are slidably connected to the guide rails 14. The frame 2 is fixedly connected to the sliders, and the frame 2 slides on the guide rails 14 via the sliders. The upper surface of the base 3 is used to place the substrate to be coated. The frame 2 is equipped with a coating bar 4, a scraper 5, and a slit head 6. The coating bar 4, scraper 5, and slit head 6 are located above the base 3. When the operator places the substrate on the upper surface of the base 3, the operator pours glue onto the substrate when coating with the coating bar 4 and scraper 5. Then the frame 2 slides on the guide rail 14, and the frame 2 moves the coating bar 4 and scraper 5 above the base 3. The coating bar 4 and scraper 5 evenly coat the substrate with glue. When using slit coating, glue is added to the slit head 6. When the frame 2 moves, the slit head 6 sprays glue onto the substrate.

[0029] The frame 2 is equipped with a lifting assembly for driving the lower crossbeam 21 to rise and fall. Specifically, the lifting assembly includes a lifting rod 22 mounted on the frame 2, a cylindrical base 23 fixedly mounted on the frame 2, a lifting seat 231 mounted on the cylindrical base 23, and a handle 232 mounted on the lifting seat 231. The frame 2 is equipped with a lower crossbeam 21. The scraper 5 and the slit die head 6 are connected to the lower crossbeam 21. The bottom end of the lifting rod 22 is fixedly connected to the lower crossbeam 21. The lifting rod 22 movably passes through the cylindrical base 23. One end of the lifting seat 231 is hinged to the side of the cylindrical base 23. On the wall, the other end of the cylinder seat 23 is hinged to the side wall of the handle 232. An extension 233 is integrally formed on the handle 232. The end of the extension 233 away from the handle 232 is hinged to the side wall of the lifting rod 22 away from the lower crossbeam 21. When the scraper 5 and the slit die 6 are not used for coating, the operator rotates the handle 232. The extension 233 on the handle 232 rotates and drives the lifting rod 22 and the lower crossbeam 21 to rise, thereby raising the scraper 5 and the slit die 6. In this way, the scraper 5 and the slit die 6 will not touch the glue when the wire rod 4 is coated.

[0030] In addition, two micrometers 211 are fixedly installed on the lower crossbeam 21 along the length of the parallel lifting rod 22. A connecting block 212 is movably connected to the frame 2. The scraper 5 and the slit die 6 are fixedly installed on the connecting block 212. The micrometer screw of the micrometer 211 is fixedly connected to the connecting block 212. When it is necessary to precisely adjust the position of the scraper 5 and the slit die 6, the operator can precisely adjust the position of the scraper 5 and the slit die 6 through the micrometer 211, thereby making the coating accuracy higher. In addition, a spring 213 is connected between the lower crossbeam 21 and the connecting block 212. One end of the spring 213 is connected to the lower crossbeam 21, and the other end of the spring 213 is connected to the upper cover of the connecting block 212. The spring 213 can provide a certain tension to the connecting block 212, making it easier for the connecting block 212 to return to its original position. In addition, the scraper 5 and the slit die head 6 are fixedly connected to the connecting block 212 by multiple fixing bolts, which facilitates the disassembly of the scraper 5 and the slit die head 6. At the same time, mounting holes are provided on both opposite sides of the frame 2. The upper diameter of the mounting hole is larger than the diameter of the wire rod 4. The wire rod 4 is inserted into the lower part of the mounting hole. A limit rod 24 is provided on the frame 2. The limit rod 24 abuts against the circumference of the wire rod 4. The limit rod 24 is fixed to the frame 2 by bolts. The wire rod 4 can be removed by removing the limit rod 24.

[0031] In addition, the base 1 is provided with a drive assembly that drives the frame 2 to move above the base 3. Specifically, the drive assembly includes a drive motor fixedly mounted on the base 1, a drive synchronous pulley 11 coaxially fixedly connected to the output shaft of the drive motor, a driven synchronous pulley 12 rotatably connected to the base 1, and a synchronous belt 13 connecting the drive synchronous pulley 11 and the driven synchronous pulley 12. The frame 2 is fixedly connected to the synchronous belt 13. The drive motor drives the drive synchronous pulley 11 to rotate, thereby driving the synchronous belt 13 to move. The synchronous belt 13 drives the frame 2 to slide on the guide rail 14, thereby moving the frame 2, which makes coating more convenient.

[0032] In addition, both ends of the base 3 are equipped with fixing plates 31, which are attached to the upper surface of the base 3. Adjusting bolts 311 are threadedly connected between the fixing plates 31 and the base 3. The ends of the substrate are located between the fixing plates 31 and the base 3. After the operator places the substrate on the base 3, they tighten the adjusting bolts 311, thereby clamping the substrate between the fixing plates 31 and the base 3. Alternatively, a heating plate 32 can be installed on the base 3. The heating plate 32 can be electrically heated and can heat the applied adhesive or substrate to meet various process requirements. Alternatively, a suction plate 33 can be installed on the base 3. The suction plate 33 has multiple suction holes. After the operator places the substrate on the base 3, the suction plate 33 vacuum-adheres the substrate, making it flatter and more secure. Both the heating plate 32 and the suction plate 33 can be installed simultaneously. The base 3 is preferably made of aluminum or marble, as these two materials offer better durability.

[0033] The implementation principle of this utility model embodiment of a three-in-one flat plate coating testing machine combining wire bar, doctor blade, and slit coating is as follows: The operator places the substrate on the base 3, then tightens the adjusting bolts 311 at both ends of the base 3 to clamp and fix the substrate. When using wire bar 4 for coating, the doctor blade 5 and slit die head 6 are raised to pour the coating adhesive onto the substrate. Then, the drive motor drives the frame 2 and wire bar 4 to move, and the wire bar 4 evenly coats the adhesive onto the substrate. When using doctor blade 5 for coating, the operator removes the slit die head 6 and wire bar 4. When using slit coating, the operator removes the doctor blade 5 and wire bar 4. Thus, one machine can meet multiple coating methods, resulting in lower costs.

Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
