[0034] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments 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 any creative efforts shall fall within the scope of protection of the present invention.

[0035] The present invention will be further described below with reference to the embodiments.

[0036] Example:

[0037] Refer to the attached Figure 1-Attached Figure 9 As shown in, the fully automatic high-speed green environmental protection laminating machine includes a transmission component for transmitting the coated object 1, including two first conveying rollers 100 arranged in a symmetrical structure, and two symmetrically arranged second conveying rollers 110 located in the middle of the two first conveying rollers 100. Specifically, limiting rings are fixedly installed at both ends of the first conveying roller 100; the inner outer wall of the limiting ring contacts the outer wall of the coated object 1 to limit the conveying trajectory of the coated object 1. In the actual transmission process, the rotation speed of the set first conveying roller 100 is kept constant, and the limiting rings set at both ends of the first conveying roller 100 will limit the conveying trajectory of the coated object 1 located in the middle of the two limiting rings. It is worth noting that the coated object 1 transmitted on the two first conveying rollers 100 has a coating length perpendicular to the conveying direction that is less than the axial length of the two first conveying rollers 100. After coating is completed, the required length can be obtained by cutting; it is worth noting that the two second conveying rollers 110 are set in the transmission component. The feeding roller 110 can also assist in the transmission of the coated object 1. At the same time, in this case, the coating station is also located in the middle of the two second conveying rollers 110. In this case, in order to adjust the transmission trajectory of the coated object 1, a pressure roller 400 is also provided. It is located in the middle of the two movable plates 340 and is on the upper side of the elastic belt 350. It is used to squeeze the elastic belt 350 so that the elastic belt 350 fits the surface of the coated object 1. The set pressure roller 400 can change the transmission trajectory of the coated object 1 being transmitted, and it is similar to a U-shaped structure, so that the coated object 1 forms two symmetrical inclined planes. In order to facilitate the subsequent better explanation of this technical solution, the inclined plane close to the front end of the transmission is called the first inclined plane, and the inclined plane away from the front end of the transmission is called the second inclined plane. In this way, a certain amount of liquid coating liquid will accumulate here, and coating is achieved in this way. As the coated object 1 is continuously transported, the excess liquid coating liquid automatically slides down under the action of gravity to complete a coating of a certain thickness.

[0038] Specifically, the laminating machine also includes a mounting plate 200, which is arranged at the upper side of the coating object 1, and a hot melt tube 210 is installed in the middle of the mounting plate 200. The hot melt tube 210 can melt the solid coating glue, and the lower end of the hot melt tube 210 passes through the mounting plate 200 and is fixedly connected to a discharge pipe 220. It is worth noting that the discharge pipe 220 is located in the middle of the two second conveying rollers 110, and the specific outlet position of the discharge pipe 220 is located at the upper side of the first inclined surface. In this way, under the action of gravity, the liquid coating liquid will make the first contact with the coating object 1 and be coated, and the conveying speed of the coating object 1 is consistent with that of the liquid. There is a speed difference in the sliding speed of the coating liquid, so that the liquid coating liquid can be well contacted with the coating object 1 to achieve preliminary coating before sliding to the lowest point, and hot air components and air blowing components are respectively installed on both sides of the hot melt tube 210 along the transmission direction of the coating object 1, respectively preheating the surface of the coating object 1 before coating and air-drying the coating object 1 after coating. By preheating the coating object 1 in advance before coating, the sliding of the liquid coating liquid on the surface of the coating object 1 can be improved to ensure the coating quality. At the same time, the surface of the coating object 1 has a certain temperature, which also makes the coating object 1 better contact with the liquid coating liquid.

[0039] The laminating machine includes a moving part 300, which is arranged in the middle of the two second conveying rollers 110 and is movably connected to the mounting plate 200, and the moving part 300 is fixedly connected to the output end of the external cylinder through the connecting column 310, which is used to adjust the distance of the moving part 300 relative to the coating object 1 in the vertical direction. A limiting groove 201 is also fixedly installed on the mounting plate 200 to limit the moving trajectory of the moving part 300 in the vertical direction. The distance between the set moving part 300 and the mounting plate 200 can be adjusted by the external cylinder, and the moving part 300 can be moved closer to or away from the coating object 1. The upper surface of the cloth object 1, the two ends of the moving part 300 are also fixedly connected to the connecting parts 320, the two ends of the connecting part 320 are respectively fixedly connected to the clamping parts 321, and the movable plate 340 is movably connected in the clamping part 321. The lower ends of the two movable plates 340 are connected by an elastic band 350. First, the movable plate 340 and the clamping part 321 fixedly connected to the connecting part 320 maintain a sliding connection. The two movable plates 340 can move away from or approach each other in the horizontal direction, and the lower sides of the two movable plates 340 on the same side are connected to an elastic band 350. The elastic belt 350 is elastic. Specifically, when the two movable plates 340 move away from each other, it can be stretched. It is worth noting that the width of the elastic belt 350 is smaller than the width of the coating object 1. When it contacts the outer wall of the pressure roller 400, it will present a U-shaped structure. Then, by adjusting the distance between the two movable plates 340, the elastic belt 350 can be closely attached to the upper surface of the coating object 1. A holding groove is formed between the middle parts of the two elastic belts 350, and the holding groove is used to hold A temporary storage space is provided for the liquid coating liquid that slides down the first inclined surface after the coating object 1 is squeezed. In the holding tank, the liquid coating liquid can fully contact the surface of the coating object 1 to achieve high-quality coating. Compared with the existing single coating method, it may be due to impurities on the surface of the coating object 1. For example, if the coating object 1 is a fiber product, the fibers on its surface will hinder the liquid coating liquid from contacting the coating object 1 well. In this solution, it can be understood that coating is achieved by a short immersion method. Of course, the thickness of the elastic band 350 is much larger than the thickness of the coating layer.

[0040] In addition, a scraper 330 is movably connected to the lower end of the movable part 300, and its specific setting position is on the upper side of the second inclined surface, and can remain perpendicular to the coating object 1. It should be noted that when the coating object 1 is at the second inclined surface, it has been immersed and coated. In order to ensure that the thickness of the coating layer remains consistent, the scraper 330 is set to scrape off excess coating liquid, and during the continuous movement of the coating object 1, a certain amount of liquid coating liquid will accumulate on the surface of the scraper 330, and due to the action of gravity, it will fall back to the middle position of the first inclined surface and the second inclined surface, realizing reuse and environmental protection.

[0041] In particular, during the actual coating process of the laminating machine, liquid coating liquid will accumulate in the middle of the U-shaped coating object 1. Therefore, in this case, a storage chamber 401 is opened inside the pressure roller 400, and a plurality of liquid inlet holes 402 that are connected to the storage chamber 401 are evenly opened on the inner end surface of the pressure roller 400; the outer end of the pressure roller 400 is connected to the cylinder 500 through the connecting tube 410, and the connecting tube 410 is provided with a pump body. Through the provided pump body, the excess liquid coating liquid on the surface of the coating object 1 can be recovered through the provided liquid inlet holes 402 and the provided storage chamber 401. On the one hand, the accumulation of a large amount of liquid coating liquid on the coating object 1 will cause the liquid coating liquid to overflow, resulting in waste, and will also lead to excessive immersion coating, which is understood to be a large amount of liquid coating liquid that will soak into the coating object 1, resulting in excessive coating and the formation of defective products.

[0042] At the same time, in this scheme, a cylinder 500 is also provided, and a liquid storage chamber 501 and an air storage chamber 502 are respectively provided on both sides of the inner end of the cylinder 500; a separating plate 510 is provided between the liquid storage chamber 501 and the middle part of the air storage chamber 502 and is slidably matched with the inner wall of the air storage chamber 502, and the separating plate 510 is elastically connected to the inner wall of the air storage chamber 502; the liquid storage chamber 501 is connected to the hot melt tube 210 through a hose 520; when the pump body installed on the connecting pipe 410 is running, the excess liquid coating remaining on the coating object 1 will enter the interior of the storage chamber 401, and enter the liquid storage chamber 501, and re-enter the hot melt tube 210 through the provided hose 520. When the pump body provided on the connecting pipe 410 extracts the accumulated liquid coating liquid, the liquid coating liquid The coating liquid will enter the liquid storage chamber 501 through the liquid inlet hole 402, the storage chamber 401, and the connecting tube 410, and squeeze the partition plate 510 that is slidably connected to the gas storage chamber 502, causing it to displace, and the gas originally in the gas storage chamber 502 is squeezed out from the provided circular tube 530; and when the provided partition plate 510 is squeezed into place, that is, when the elastic member provided between the partition plate 510 and the gas storage chamber 502 can no longer be compressed, the liquid coating liquid in the liquid storage chamber 501 is re-entered into the hot melt tube 210 through the provided external liquid pump through the hose 520 and reused. It is worth noting that in this process, in order to ensure that the coating liquid is always in liquid form, the laminating machine can be placed in a sealed environment with a certain temperature. It is worth noting that the operation of the pump body is intermittent, which can be controlled by an external intermittent control unit or by a manual trigger switch. When the liquid pump is running, the pump body stops running, so that the liquid pump can pump most of the liquid coating liquid in the liquid storage chamber 501 into the hot melt tube 210. At this time, under the action of the elastic member, the separating plate 510 can be reset.

[0043] In this case, in order to ensure that the liquid coating liquid can better fully contact the coating object 1, it also includes a rotating part 600, which is symmetrically arranged with two and located at the lower side of the coating object 1; a plurality of protrusions 610 are evenly and fixedly connected on the outer wall of the rotating part 600, and a cavity 601 is provided on the inner and outer sides of the rotating part 600, and also includes a plurality of spiral grooves 602 provided between the inside of the cavity 601 and the inner end thereof; a sleeve 700 is sleeved in the middle of the two rotating parts 600, and the outer wall of the rotating part 600 slides with the inner wall of the through groove 701 provided inside the sleeve 700, and the cavity 601 is kept in communication with the through groove 701 through the spiral groove 602; and an air outlet is also provided on the sleeve 700. It also includes a circular tube 530 for connecting the air storage chamber 502 with the cavity 601; and the circular tube 530 is a hard tube, and its outer wall is rotatably connected to the overlap plate 230 fixedly connected to the mounting plate 200; when the separating plate 510 moves to one side, the gas in the air storage chamber 502 will pass through the cavity 601 and the spiral groove 602 into the through groove 701, and be discharged from the air outlet. During this process, when the gas circulates in the spiral groove 602, it will drive the rotating part 600 to rotate, and the protrusion 610 fixedly connected to the outer wall of the rotating part 600 will make point contact with the coating object 1, causing it to be in a vibrating state.

[0044] As described above, when the pump body is running, the gas in the gas storage chamber 502 that is movably connected will be squeezed out from the circular tube 530. Combined with the communication relationship between the circular tube 530 and the cavity 601 opened in the rotating member 600, and the communication relationship between the cavity 601 and the spiral groove 602, the pressure of the air flow will cause the two rotating members 600 sleeved in the sleeve 700 to rotate. Since a plurality of protrusions 610 are evenly fixedly connected to the outer wall of the rotating member 600, the outer wall of the protrusion 610 will contact the coating object 1 during the rotation process. The lower surface is in contact, so that the coating object 1 in the middle of the two elastic bands 350 can be in a vibrating state, so that the liquid coating liquid can better contact the coating object 1, ensuring the coating effect. It is worth noting that although the elastic band 350 is also affected by the vibration, it has a certain stability due to its stretched relationship, so it will not be easily carried by the synchronous vibration; at the same time, in this process, when the pump body is running, the liquid coating liquid in the U-shaped structure is more easily adsorbed, effectively avoiding the problem that the liquid coating liquid is always in the same position and is not easy to be adsorbed and recovered.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present invention.
