Description

Technical Field

[0001] This utility model relates to the field of coating machine technology, specifically an adaptive and autonomous control coating device. Background Technology

[0002] Coating machines are mainly used for surface coating processes of films, paper, etc. This machine coats a roll of substrate with a layer of adhesive, paint or ink with specific functions, and then dries it before cutting it into sheets or rewinding it. It uses a special multi-functional coating head to achieve various forms of surface coating. When coating films and paper, it can automatically adjust the coating thickness and control the raw material tension.

[0003] The aforementioned technologies have certain shortcomings in their application: when coating films or paper, a dedicated coating head is used to coat the paper surface. However, different types of paper have different coating thickness requirements during the processing. Furthermore, the paper has a certain tension to maintain flatness during coating, and the tension of different types of paper varies. It is necessary to control the tension during coating to prevent excessive tension from causing the paper to break due to over-tightening. Therefore, a coating device that can automatically adjust the coating thickness and regulate the paper tension is needed.

[0004] To address these issues, this invention provides an adaptive and autonomously adjustable coating device. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides an adaptive and autonomously adjustable coating device, which solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an adaptive autonomous control coating device, including a base, with side plates fixedly installed on the front and rear parts of the top wall of the base, a flattening component for flattening the coated paper installed on the left side between the two side plates, a control component installed in the middle between the two side plates, and a coating control component installed on the right side between the two side plates. The coating control assembly includes a positioning frame fixedly installed between two side plates. A coating head is fixedly installed on the inner wall of the positioning frame. An extension plate is fixedly installed on the side wall of the positioning frame. A lifting push rod is fixedly installed on the top wall of the extension plate. A scraper seat is fixedly installed through the movable end of the lifting push rod via the extension plate. A scraper is fixedly installed on the bottom wall of the scraper seat. A distance sensor is fixedly installed on the side wall of the scraper seat. The same coating table is fixedly installed between the two side plates and at the positions corresponding to the scrapers.

[0007] Through the above technical solution, the coating control component can adjust the coating thickness according to different coating requirements after adjusting the position of the doctor blade holder and doctor blade by lifting the push rod when the paper coating work begins. The distance sensor monitors the distance between the paper and the doctor blade in real time and performs autonomous control.

[0008] Furthermore, the top of the coating head is connected to an external feeding device through a feed pipe, and positioning rods are fixedly installed on the front and rear parts of the top wall of the scraper seat. The tops of the two positioning rods slide through the extension plate and extend to the outside. A collection frame is fixedly installed on the top wall of the base at a position corresponding to the bottom of the coating head.

[0009] The positioning rod, as described above, is designed to limit the path of the scraper seat during lifting and lowering in real time, preventing path deviation.

[0010] Furthermore, the flattening assembly includes a support roller rotatably mounted between two side plates, with a cross groove provided on the left side of each side plate, and a cross seat slidably mounted on the inner wall of each cross groove.

[0011] Through the above technical solution, the support roller can stably support the paper passing through, while the cross seat slides up and down in the inner wall of the cross groove.

[0012] Furthermore, both cross seats are equipped with abutment springs on their top walls, and the tops of both abutment springs are fixedly connected to the top wall inside the cross groove. Pressure rollers are rotatably installed on the adjacent sides of both cross seats.

[0013] Through the above technical solution, the abutment spring pushes the cross seat and the pressure roller to apply a certain pressure to the paper surface through its elastic action.

[0014] Furthermore, the control assembly includes several guide rollers rotatably mounted between the two side plates, with the guide rollers arranged in a staggered manner.

[0015] The above technical solution uses guide rollers primarily to guide the paper to feed smoothly.

[0016] Furthermore, mounting grooves are provided on the front and rear walls of both side panels, electric slide rails are installed on the inner walls of both mounting grooves, and electric sliders are slidably installed on the inner walls of both electric slide rails.

[0017] With the above technical solution, when the electric slider slides along the inner wall of the electric slide rail, it will drive the detection roller to adjust and slide synchronously.

[0018] Furthermore, the same detection roller is installed on the adjacent side of the two electric sliders. The outer wall of the detection roller is provided with an embedded groove, and a pressure sensing plate is fixedly installed on the inner wall of the embedded groove. The pressure sensing plate is located on the upper part of the detection roller.

[0019] With the above technical solution, when the paper passes through the pressure sensing plate and the paper tension pressure is detected to be too high, the tension can be reduced by lowering the detection roller, which has a protective effect on the stable conveying of the paper. Beneficial effects

[0020] This invention provides an adaptive and autonomously adjustable coating device. Compared with the prior art, it has the following advantages: (1) The adaptive autonomous control coating device, through the setting of coating control components and control components, can autonomously control the tension of the paper in real time during the feeding process when coating the paper, which can prevent the paper from breaking and has a good protective effect. It can also control the coating thickness in real time and adjust the position of the doctor blade during coating, so that the material coverage is more uniform throughout the coating process.

[0021] (2) The adaptive autonomous control coating device, through the setting of the flattening component, mainly applies a certain pressure to the surface of the paper when the paper is being transported, and flattens any wrinkles that may exist on the surface, so as to prevent them from affecting the uniformity of the coating in the future.

Example

[0026] Please see Figures 1-5 This embodiment provides a technical solution based on embodiment one: the flattening assembly 3 includes a support roller 31 rotatably installed between two side plates 2, a cross groove 32 is provided on the left side of each of the two side plates 2, a cross seat 34 is slidably installed on the inner wall of each of the two cross grooves 32, an abutment spring 35 is installed on the top wall of each of the two cross seats 34, the top of each of the two abutment springs 35 is fixedly connected to the top wall of the inner wall of the cross groove 32, and a pressure roller 33 is rotatably installed on the adjacent side of each of the two cross seats 34; In this embodiment of the utility model, the purpose of this arrangement is that the flattening component 3 can apply a certain pressure to the paper through the support roller 31 and the pressure roller 33, so as to smooth out any wrinkles that may exist on the paper surface and improve the uniformity of subsequent coating. Example

[0027] Please see Figures 1-5 This embodiment provides a technical solution based on embodiment one: the control component 4 includes a plurality of guide rollers 41 rotatably mounted between two side plates 2. The plurality of guide rollers 41 are staggered with each other. The front and rear walls of the two side plates 2 are provided with mounting grooves 42. The inner walls of the two mounting grooves 42 are provided with electric slide rails 43. The inner walls of the two electric slide rails 43 are slidably mounted with electric sliders 44. The same detection roller 45 is installed on the adjacent side of the two electric sliders 44. The outer walls of the detection rollers 45 are provided with embedded grooves 46. The inner walls of the embedded grooves 46 are fixedly mounted with pressure sensing plates 47. The pressure sensing plates 47 are located on the upper part of the detection rollers 45. In this embodiment of the utility model, the purpose of this setting is that the setting of the control component 4 is mainly to adapt and adjust the tension of the paper during the conveying process. When the pressure sensing plate 47 on the detection roller 45 detects that the tension of the paper is too high, the tension of the paper can be reduced by lowering the position of the detection roller 45, which has the function of stabilizing the feeding and protecting the paper.

[0028] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0029] The working principle of this device is as follows: The movable pressure roller 33 drives the cross seat 34 to slide upward in the inner wall of the cross groove 32, so that the cross seat 34 compresses the abutment spring 35, so that the pressure roller 33 moves away from the support roller 31 to provide space for the paper to enter. After the paper passes between the support roller 31 and the pressure roller 33, it passes through the outer wall of the guide roller 41 and the detection roller 45 in sequence, and finally enters the coating head 54 and the bottom position of the doctor blade 510 to extend to the outside, and connects with the winding device of the coating machine. At the same time, after the pressure roller 33 is released, the cross seat 34 is pushed downward in the inner wall of the cross groove 32 by the elastic action of the abutment spring 35, so that the pressure roller 33 is close to the outer wall of the support roller 31 to apply a certain pressure to the paper that has passed through. The paper passing through the positioning frame 53 and the bottom of the coating head 54 is continuously discharged through the coating head 54, and the coating liquid raw material is continuously supplied to the coating head 54 through the feed pipe 55 by the external feeding equipment. The coating raw material is discharged from the bottom of the coating head 54 onto the surface of the paper. The lifting push rod 57 is activated to push the doctor blade seat 59 and doctor blade 510 down, so that the doctor blade 510 can evenly scrape the coating raw material on the paper surface. During the scraping process, excess coating raw material will fall into the collection box 51 for unified collection and recycling. During the descent of the doctor blade seat 59, the positioning rod 58 will move downward to limit the movement path of the doctor blade seat 59 and prevent the doctor blade 510 from deviating from its position. When the doctor blade seat 59 is rising and falling, the distance sensor 511 monitors the distance between the doctor blade seat 59 and the paper on the coating table 52 in real time and transmits the distance to the coating machine in real time. Through the built-in running program, the height of the doctor blade 510 and doctor blade seat 59 can be automatically adjusted according to the coating thickness, so as to automatically adapt to meet diverse coating requirements. Simultaneously, the tension pressure of the paper passing over the surface of the detection roller 45 and the pressure sensing plate 47 is detected in real time by the pressure sensing plate 47. When the pressure is too high, the electric slider 44 moves linearly along the electric slide rail 43 installed in the inner wall of the mounting groove 42. The electric slider 44 drives the detection roller 45 and the pressure sensing plate 47 to descend, so that the tension of the paper passing over the surface of the pressure sensing plate 47 decreases slowly, avoiding paper breakage and optimizing the protection of the paper during the coating process.
