[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0030] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-3 A coating device with uniform scraping function includes a frame 1, an adjustable coating structure 2, a heating roller 3, an adjustable scraping structure 4, a cooling roller 5, and a tension adjustment module 6.

[0031] A conveyor 11 for conveying materials is fixedly installed on the frame 1, and multiple guide rollers 12 are rotatably installed on the frame 1; an adjustable coating structure 2 is installed on the upper side of the frame 1; a heating roller 3 is rotatably installed on the right side of the frame 1; an adjustable scraping structure 4 for scraping the adhesive on the material is installed on the lower right side of the frame 1; and a cooling roller 5 is rotatably installed on the lower side of the frame 1.

[0032] like Figure 2 and Figure 3 As shown, the adjustable coating structure 2 includes an adjustable coating roller 21 and a drive structure 22. Two adjustable coating rollers 21 are rotatably mounted on the frame 1, and a drive structure 22 for driving the two adjustable coating rollers 21 to rotate is mounted on the frame 1.

[0033] like Figure 2As shown, the adjustable leveling structure 4 includes an adjustable leveling module 41 and a straightness measuring module 42. The adjustable leveling module 41 for scraping off the adhesive is installed on the frame 1, and the straightness measuring module 42 for detecting the adjustable leveling module 41 is installed on the adjustable leveling module 41.

[0034] In this embodiment, when the coating equipment with uniform leveling function is working normally, adhesive is fed between the two adjustable coating rollers 21. The material is conveyed by the conveyor 11 and moves to the lower side of the adjustable coating rollers 21. The drive structure 22 drives the two adjustable coating rollers 21 to rotate, thereby coating the material between the two adjustable coating rollers 21 onto the material. Then the material moves to the heating roller 3, where the heating roller 3 heats the material, slowing down the curing of the adhesive on the material. Then the adjustable leveling module 41 further levels the adhesive on the material. The material is leveled and the scraped adhesive is collected. The status of the adjustable leveling module 41 is detected by the straightness measuring module 42 to determine whether the adjustable leveling module 41 is parallel to the heating roller 3, thereby ensuring the leveling effect. Then the material is moved to the cooling roller 5, where the material and the adhesive on it are cooled, thereby accelerating the curing of the adhesive on the material. The coating operation of the material is completed. During this process, the tension of the material is adjusted by the tension adjusting module 6 to ensure that the material remains flat during the coating process, which facilitates the coating of the material.

[0035] Example 2: In some embodiments, as a preferred embodiment of the present invention, such as... Figures 2-3 and Figure 5 As shown, the adjustable coating roller 21 includes a combined coating roller and a limiting installation structure. The limiting installation structure is mounted on the frame 1, and the combined coating roller is mounted on the limiting installation structure.

[0036] The limiting installation structure includes a rotating shaft 211 and a limiting stop 212. The rotating shaft 211 is rotatably mounted on the frame 1, and the middle part of the rotating shaft 211 is square. The limiting stops 212 are symmetrically fixedly installed on both sides of the rotating shaft 211.

[0037] The combined coating roller includes a first sliding roller 213, a second sliding roller 214, insert blocks 215, and a baffle plate 217. The first sliding roller 213 is slidably connected to the middle of the rotating shaft 211. The second sliding rollers 214 are symmetrically arranged on both sides of the rotating shaft 211 and are slidably connected to the rotating shaft 211. The second sliding rollers 214 are inserted into the limiting stop 212. Insert blocks 215 are fixedly installed at both ends of the first sliding roller 213 and at the outer end of the second sliding roller 214. A slot 216 is opened on the inner side of the second sliding roller 214. The insert blocks 215 are inserted into the slots 216. Adjacent insert blocks 215 form a baffle groove, and the baffle plate 217 is inserted into the baffle groove.

[0038] The drive structure 22 includes a servo motor 221 and a gear 222. The servo motor 221 is fixedly mounted on the frame 1, and the output end of the servo motor 221 is fixedly connected to a rotating shaft 211. A gear 222 is fixedly mounted on the end of the rotating shaft 211. The two gears 222 are meshed together.

[0039] like Figure 3 and Figure 4 As shown, the adjustable leveling module 41 includes an adjustment mounting module and a leveling module. The adjustment mounting module is mounted on the frame 1, and the leveling module is mounted on the adjustment mounting module.

[0040] The adjustment and installation module includes guide rails 411, a movable frame 412, a threaded rod 413, and a handwheel 414. The guide rails 411 are symmetrically fixedly installed on the frame 1, and the movable frame 412 is slidably connected to the two guide rails 411. One end of the threaded rod 413 is rotatably installed on the frame 1, and the other end of the threaded rod 413 is fixedly installed with a handwheel 414. The threaded rod 413 is threadedly connected to the movable frame 412 through a threaded sleeve.

[0041] The leveling module includes a scraper 416, the scraper 416 is fixedly installed on the upper side of the movable frame 412, and a material storage trough 415 for storing materials is opened on the upper side of the movable frame 412.

[0042] The straightness measurement module 42 includes a mounting plate 421 and a pressure sensor 422. The pressure sensor 422 is symmetrically fixedly mounted at both ends of the movable frame 412; the mounting plate 421 is symmetrically fixedly mounted on both sides of the frame 1; the mounting plate 421 abuts against the pressure sensor 422.

[0043] like Figure 4 As shown, the tension adjustment module 6 includes a support frame 61, an adjusting roller 62, a slide rod 63, and a spring 64. Multiple slide rods 63 are symmetrically fixedly installed on the lower side of the frame 1. The support frame 61 and the slide rods 63 are connected in a limited sliding connection. The adjusting roller 62 is rotatably installed on the support frame 61. The adjusting roller 62 is in rolling contact with the material. A spring 64 is sleeved on the lower side of the slide rod 63. One end of the spring 64 is fixedly connected to the support frame 61, and the other end of the spring 64 is fixedly connected to the frame 1.

[0044] In this embodiment, when the adjustable coating structure 2, heating roller 3, adjustable leveling structure 4, cooling roller 5, and tension adjustment module 6 are working normally, the relative positions of the first sliding roller 213 and the second sliding roller 214 are adjusted according to the material size. If the material size is small, the second sliding rollers 214 at both ends can be inserted into the limiting stop 212. At this time, the insert 215 between the second sliding roller 214 and the first sliding roller 213 is exposed, and the glue baffle 217 is inserted into the insert 215 located between the first sliding roller 213 and the second sliding roller 214. If the material size is wide, the slot 216 on the second sliding roller 214 is inserted into the insert 215 on the first sliding roller 213, so that the first sliding roller 214 is wide. A sliding roller 213 is combined with a second sliding roller 214. At this time, the insert block 215 at the outer end of the second sliding roller 214 is exposed, and the glue baffle 217 is inserted between the second sliding roller 214 and the limiting stop 212. This allows it to adapt to materials of different sizes. In use, the adhesive is placed between the first sliding roller 213 and the second sliding roller 214 and the glue baffle 217. The servo motor 221 drives a rotating shaft 211 to rotate, which in turn drives another rotating shaft 211 to rotate through two gears 222. This causes the first sliding roller 213 and the second sliding roller 214 on the rotating shaft 211 to rotate, thus coating the adhesive onto the material on the lower side.

[0045] The middle part of the first slide roller 213 and the second slide roller 214 is set as a square to cooperate with the middle part of the rotating shaft 211, so that the first slide roller 213 and the second slide roller 214 can be driven to rotate by the rotating shaft 211, and can slide relative to the rotating shaft 211; thus, when making adjustments, the relative position between the first slide roller 213 and the second slide roller 214 can be changed.

[0046] Before use, the positions of the moving frame 412 and the scraper 416 on the moving frame 412 can be adjusted according to the required thickness of the material and adhesive. Turning the handwheel 414 drives the threaded rod 413 to rotate, and the rotation of the threaded rod 413 drives the moving frame 412 to move. The moving frame 412 moves horizontally under the limiting action of the guide rail 411, thereby driving the scraper 416 to move horizontally. During this process, if the moving frame 412 is tilted, the distance between the pressure sensors 422 at both ends of the moving frame 412 and the moving frame 412 will be different. At this time, the readings of the two pressure sensors 422 that are in contact with the mounting plates 421 at both ends will be different.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
