Abstract
Description
Technical Field
[0001] This utility model relates to the field of coating machines, and more particularly to a water-based coating machine. Background Technology
[0002] A water-based coating film-making machine is a device used to prepare water-based coating films. By uniformly applying water-based coatings to a specific substrate and controlling parameters such as film thickness and speed, a coating film with specific specifications and properties is prepared. Typically, a doctor blade, wire rod, or other coating methods are used to smoothly coat the coating onto the substrate surface.
[0003] A search revealed Chinese Patent Publication No. CN221017077U, which discloses a water-based coating machine, comprising a feeding syringe and a feeding box. A piston is slidably connected to the inner wall of the feeding syringe, and a piston rod is fixedly connected to one end of the piston. The feed inlets at the top left and right ends of the feeding syringe are respectively connected to the discharge outlets at the bottom left and right sides of the feeding box via a first feed pipe and a second feed pipe. This relates to the field of coating machine technology. By setting a second feed pipe and a first feed pipe on the top two sides of the feeding syringe respectively to connect to the discharge outlets of the feeding box, and setting a first feed port and a second feed port on the bottom two sides of the feeding syringe respectively, by closing the valve on the first feed pipe, opening the valve on the second feed pipe, closing the valve on the second feed port, and opening the valve on the first feed port, or by opening the valve on the first feed pipe, closing the valve on the second feed pipe, opening the valve on the second feed port, and closing the valve on the first feed port, the machine can continuously feed material into the rubber roller, thereby making the feeding continuous.
[0004] The aforementioned document does achieve the goal of continuously feeding material into the rubber roller, thus ensuring a smooth feeding process. However, the position and angle of the scraper are still difficult to adjust precisely, which can easily lead to uneven coating thickness on the substrate and uneven surface, severely affecting the coating quality. Therefore, a water-based coating machine is proposed. Utility Model Content

This drastically shortens the drying time of the coating and improves production efficiency. Attached Figure Description

[0041] Reference Figure 4The inner wall of the sliding frame 4 is provided with a second sliding groove 17. The outer side of the sliding plate 9 is slidably connected to the inside of the second sliding groove 17. The second sliding groove 17 provides a sliding track for the sliding plate 9, ensuring the stable movement of the sliding plate 9 within the sliding frame 4.
[0042] Reference Figure 3 and Figure 4 The first locking tooth 11 and the second locking tooth 14 engage to fix the position of the sliding plate 9, thereby fixing the position of the scraper 5. The end of the spring 12 away from the limiting plate 10 is fixedly connected to the inner wall of the sliding plate 9, so that the spring 12 can play the role of reset and buffer in the adjustment assembly.
[0043] Reference Figure 5 and Figure 6 The end of the connecting rod 22 away from the rotating frame 21 passes through the cylinder 23 and is fixedly connected to the upper side of the piston 24. The connecting rod 22 converts the reciprocating swing motion of the rotating frame 21 into the up-down linear motion of the piston 24.
[0044] Working Principle: When coating water-based materials, the material is fed into the feeder 8 through the connecting pipe on the upper side of the feeder 8. Then, two servo motors 2 are started, which rotate the lead screw 3 and the reciprocating lead screw. The reciprocating lead screw drives the mounting frame 7 to slide back and forth, evenly placing the material on the coating substrate 6. The lead screw 3 rotates, driving the sliding frame 4 to slide, which in turn drives the scraper 5 to slide and coat the material. At the same time, the rotation of the lead screw 3 also drives the disc 18 to rotate, which in turn drives the eccentric shaft 19 to rotate, causing the limit block 20 to slide up and down. This further drives the rotating frame 21 to slide up and down, which in turn drives the piston 24 to slide up and down through the connecting rod 22. The piston 24 slides up and down, causing the cylinder 23 to move up and down. The air pressure in the part is changed to extract and transport air. During the air transport, the air is heated by the heating wire 28 inside the heating shell 27, so that the air coming out of the air blowing plate 29 is hot air, which is convenient for drying the scraped material. When the height of the scraper needs to be adjusted, the pull rod 13 is pulled, and the pull rod 13 slides, which drives the limiting plate 10 to slide and squeezes the sliding plate 9. At the same time, the sliding of the pull rod 13 also drives the second locking tooth 14 to slide. When the second locking tooth 14 disengages from the engagement between the first locking tooth 11, the height of the scraper 5 can be adjusted. After the adjustment is completed, the pull rod 13 is released, and the spring force of the spring 12 pushes the first locking tooth 11 to reset, so that the first locking tooth 11 and the second locking tooth 14 engage.
[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
