[0002] In the coating industry, gravure coating machines are widely used due to their high-precision and high-efficiency coating effects. However, traditional coating mechanisms have certain defects in the coating process. For example, in the Chinese patent with the announcement number "CN 218502490U", a single-sided gravure coating mechanism is disclosed, including a frame, a feed roller, and a discharge roller. The frame includes two side plates arranged opposite to each other, the feed roller is rotatably arranged at the bottom end of one side of the two side plates, and the discharge roller is rotatably arranged at the top end of the other side of the two side plates. It also includes at least two gravure rollers and a plurality of approach rollers arranged between the two side plates for coating the slurry on the surface of the substrate. The two gravure rollers are distributed in sequence from bottom to top, and the two ends of each gravure roller are rotatably arranged on the inner side of the two side plates. The multiple approach rollers are located on one side of the two gravure rollers. , the multiple approach rollers are distributed in sequence from bottom to top, and the multiple approach rollers can move horizontally relative to the two side plates in the direction of approaching or moving away from the two gravure rollers, so as to make the substrate contact with the two gravure rollers or separate the substrate from the two gravure rollers. By setting at least two gravure rollers, the surface of the substrate can be coated at least twice. Although the device can perform gravure coating, the gravure of the device is an integrated structure. Therefore, as the use time increases, the gravure will gradually wear out. Therefore, the device needs to replace the gravure regularly, and it takes a long time to stop the machine to complete the replacement, which reduces the processing efficiency of the device. In addition, the device needs to be replaced as a whole when replacing the gravure, and the use cost is high. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figures 1-9 As shown, the utility model provides the following technical solutions:

[0030] A single-sided gravure coating mechanism includes a feed member 2, which includes a feed portion and a discharge portion. A conveying channel for conveying a substrate along a preset path is formed between the feed portion and the discharge portion. A template member 1 slides between the feed portion and the discharge portion. The template member 1 is located below the conveying channel. The movement direction of the template member 1 is perpendicular to the movement direction of the substrate. The template member 1 includes a support portion and two gravure portions. The top of the gravure portion forms a coating cavity for coating the substrate. The two gravure portions are symmetrically arranged on the top of the support portion. The template member 1 slides so that one of the gravure portions is located below the conveying channel.

[0031] The coating mechanism further includes a pressing member 3 for pressing down the substrate. The pressing member 3 is located between the feeding portion and the discharging portion, and is located above the conveying channel.

[0032] Through the above technical solution, when personnel need to coat the substrate, the coating is added to the coating cavity. After the coating is added, the position of the gravure part on the template part 1 is adjusted by pulling the template part 1 to slide relative to the feed part and the discharge part, so that the gravure part moves to the bottom of the conveying channel, and then the substrate to be coated is inserted from the feed part, and the substrate is pulled out from the discharge part. The feed part and the discharge part work to drive the substrate to move. When the substrate moves to the coating position, the pressing part 3 works to press the substrate down so that the substrate contacts the coating cavity on the gravure part, and then the substrate is coated. After the substrate is coated, the above steps are repeated to continuously coat the substrate. When the personnel need to replace the gravure part, the template part 1 is pulled relative to the conveying channel to move the current gravure part on the template part 1 away from the conveying channel and the other gravure part is close to the conveying channel, so that the device can work normally, and when the device is working, the personnel can replace the gravure part that is excessively worn.

[0033] Specifically, in one embodiment, regarding the above-mentioned intaglio portion:

The mold core 111 is located inside the mold cavity 19, and a coating cavity is formed between the mold core 111 and the mold cavity 19. One side of the mold frame 18 is open to form an injection hole 112, and the injection hole 112 is connected to the mold cavity 19.

[0035] In this embodiment, when coating is required, the paint delivery pipe is connected through the injection hole 112 to deliver the paint to the coating chamber. When the substrate passes above the coating chamber, the pressing member 3 works to press the substrate down into the coating chamber, thereby completing the coating. When personnel need to replace the mold core 111, they pull the mold frame 18 to separate the mold frame 18 from the base plate 110, and then separate the mold core 111 on the base plate 110 from the mold cavity 19, and then the mold core 111 can be replaced.

[0048] In this embodiment, after the substrate passes between the two discharge rollers 26 , the second motor 27 is operated to drive the discharge rollers 26 to rotate on the second side frame 25 , thereby driving the substrate to move, and further driving the substrate to move continuously.

[0049] In addition, in the present invention, regarding how to install the first side frame 22 and the second side frame 25, as shown in FIG. Figure 1-Figure 3 、 Figure 5 As shown, the coating mechanism also includes a base frame 21, which is fixed between the first side frame 22 and the second side frame 25, and two guide plates 29 are symmetrically fixedly connected to the inner wall of the base frame 21, and the support frame 14 is slidably connected to the inside of the base frame 21, and the two symmetrical sides of the support frame 14 are recessed to form side grooves 15, and the side grooves 15 match the guide plates 29.

When a person pulls the support frame 14 to move, the guide plate 29 and the side groove 15 cooperate to make the support frame 14 move more smoothly. When the support frame 14 moves to the employee's position, the positioning screw 17 is rotated so that one end of the positioning screw 17 moves to the inside of the side groove 15 and presses against the guide plate 29, so that the adjusted position of the support frame 14 is tightened.

[0051] When the support frame 14 moves, in order to make the support frame 14 more stable, as shown in FIG. Figure 1-Figure 3 、 Figure 6-Figure 7 As shown, two support rods 11 are fixedly connected to the symmetrical sides of the support frame 14. The support rods 11 are located between the two side grooves 15, and the bottom of the support rods 11 is fixedly connected to the base frame 12.
