Description
Technical Field
[0001] This utility model relates to the field of decorative paper processing technology, specifically to a decorative paper impregnation and coating device. Background Technology
[0002] Decorative paper is widely used in the field of decorative materials. In the production of impregnated paper, the base paper needs to be immersed in adhesive solution using an impregnation device, followed by a scraping process to remove excess adhesive. Patent 221733859U discloses an impregnation adhesive treatment device for impregnated paper, including a base plate, a first impregnation tank, and a second impregnation tank. An adhesive treatment component is provided at the end of each impregnation tank. The adhesive treatment component includes a telescopic rod and a scraper rod, as well as a second scraper rod mounted via a support rod. The scraper rods scrape adhesive onto the upper and lower surfaces of the impregnated paper to prevent adhesive dripping. Furthermore, the impregnation component presses the impregnated paper into the adhesive solution using a set of limiting rollers to ensure thorough impregnation.
[0003] Existing glue-dipping devices have the following problems: the position of the glue scraper is fixed, which cannot adapt to decorative paper of different thicknesses or materials, making it difficult to adjust the glue scraping force.
[0004] Based on the above situation, there is an urgent need for a decorative paper impregnation and coating device to solve the problem of not being able to adapt to decorative papers of different thicknesses or materials. Utility Model Content
[0005] The purpose of this invention is to address the problem that existing glue-dipping devices, with their fixed glue-scraping rods, cannot adapt to decorative papers of different thicknesses or materials, resulting in difficulty in controlling the glue-scraping force.
[0006] The technical solution of this utility model is as follows: A decorative paper impregnation and coating device, comprising: Glue tank, used to store adhesive liquid; The conveying mechanism includes a bracket connected to the glue tank and a glue-impregnating roller mounted on the bracket, the glue-impregnating roller being used to continuously convey decorative base paper; The glue-applying mechanism includes a main scraper and a secondary scraper arranged sequentially along the conveying direction of the decorative base paper; The adjustment mechanism includes a rotating shaft connected to the secondary scraper and an angle adjustment assembly for driving the rotating shaft.
[0007] Existing glue-dipping devices have fixed glue-scraping rod positions, which cannot adapt to decorative papers of different thicknesses or materials, making it difficult to adjust the glue-scraping force. In this solution, the decorative base paper is continuously fed by the glue-dipping roller, allowing the base paper to be immersed in the glue solution and then moved upwards. Subsequently, the excess glue solution is scraped off by the main scraper and the secondary scraper in sequence. The angle adjustment component adjusts the angle of the secondary scraper, thereby adjusting the glue-scraping force. This effectively adapts to decorative papers of different thicknesses or materials, solving the problem of not being able to adapt to decorative papers of different thicknesses or materials.
[0008] Furthermore, this solution is not limited to the specific structure of the angle adjustment component. One feasible solution is that the angle adjustment component includes a worm gear mounted on a rotating shaft and connected to a worm. In this solution, rotating the worm drives the worm gear and the rotating shaft to rotate, thereby precisely fine-tuning the angle of the secondary scraper. Due to the self-locking characteristic of the worm gear structure, the secondary scraper can maintain a stable working position after adjustment, effectively avoiding angle deviation caused by equipment vibration or external force interference. Compared with the traditional telescopic rod adjustment method, the worm gear transmission provides higher adjustment accuracy and positional stability, thus ensuring the consistency of the scraping effect.
[0009] Furthermore, to facilitate the rotation of the worm gear, one feasible solution is to connect a knob to the worm gear. With this solution, the worm gear can be rotated conveniently and quickly by rotating the knob.
[0010] Furthermore, to adjust the scraping force of the secondary scraper, one feasible solution is as follows: the adjustment mechanism further includes a distance adjustment component, which includes a bearing connected to the rotating shaft. A guide rod is provided on the bracket and passes through the bearing. With this solution, by moving the bearing along the axial direction of the guide rod, the distance between the secondary scraper and the decorative base paper can be adjusted. This allows for flexible adjustment of the scraping contact pressure and scraping effect according to the characteristics and process requirements of different paper materials. The guide rod provides reliable linear guidance for the movement of the bearing, ensuring the stability of the bearing adjustment process.
[0011] Furthermore, to facilitate the fixing of the bearing seat, one feasible solution is to install a locking bolt on the bearing seat. When using this solution, the bearing seat and the guide rod are fixed by tightening the locking bolt.
[0012] Furthermore, to improve the glue application effect, one feasible solution is that the main scraper is a rigid scraper and the secondary scraper is a flexible scraper. When using this solution, the rigid main scraper can quickly and effectively remove most of the excess glue from the surface of the decorative base paper, completing the initial glue application. Subsequently, the flexible secondary scraper performs fine scraping, which can ensure that the glue layer is uniform and flat, and also play a good protective role for the paper surface. This effectively avoids the scratches or damage to the paper surface that may be caused by a traditional single rigid scraper, thus improving the glue application effect.
[0013] Compared with existing technologies, the beneficial effects of this utility model are: 1. Decorative base paper is continuously fed through the dip roller, so that the decorative base paper is immersed in the glue and then moved upward. Then, the excess glue is scraped off by the main scraper and the secondary scraper in sequence. The angle of the secondary scraper is adjusted by the angle adjustment component, thereby adjusting the scraping force. This can effectively adapt to decorative paper of different thicknesses or materials, and solve the problem of not being able to adapt to decorative paper of different thicknesses or materials. Second, since the angle adjustment component includes a worm gear mounted on a rotating shaft and connected to a worm, rotating the worm drives the worm gear and the rotating shaft to rotate, thereby precisely fine-tuning the angle of the secondary scraper. Due to the self-locking characteristic of the worm gear structure, the secondary scraper can maintain a stable working position after adjustment, effectively avoiding angle deviation caused by equipment vibration or external interference. Compared with the traditional telescopic rod adjustment method, the worm gear transmission provides higher adjustment accuracy and positional stability, thus ensuring the consistency of the scraping effect. Third, since the adjustment mechanism also includes a distance adjustment component, which includes a bearing connected to the rotating shaft, and a guide rod is provided on the bracket and passes through the bearing, the distance between the secondary scraper and the decorative base paper can be adjusted by moving the bearing along the axial direction of the guide rod. This allows for flexible adjustment of the contact pressure and scraping effect of the scraper according to the characteristics and process requirements of different paper materials. The guide rod provides reliable linear guidance for the movement of the bearing, ensuring the stability of the bearing adjustment process. Attached Figure Description

[0016] It should be noted that relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the term "comprising" or any other variations thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.
[0017] The features and performance of this utility model will be further described in detail below with reference to the embodiments.
[0018] Example: Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 5 A decorative paper impregnation and coating device, comprising: Glue tank 1 is used to store adhesive liquid; The conveying mechanism 2 includes a bracket 21 connected to the glue tank 1 and a glue-impregnating roller 22 mounted on the bracket 21. The glue-impregnating roller 22 is used to continuously convey the decorative base paper 3. The glue-scraping mechanism 4 includes a main scraper 41 and a secondary scraper 42 arranged sequentially along the conveying direction of the decorative base paper 3; The adjustment mechanism 5 includes a rotating shaft 51 connected to the secondary scraper 42 and an angle adjustment assembly for driving the rotating shaft 51.
[0019] Existing glue-dipping devices have fixed positions for the glue scraper, which cannot adapt to decorative paper of different thicknesses or materials, making it difficult to adjust the glue scraping force. In this solution, the decorative base paper 3 is continuously fed by the glue-dipping roller 22, so that the decorative base paper 3 is immersed in the glue and then moved upward. Then, the excess glue is scraped off by the main scraper 41 and the secondary scraper 42 in sequence. The angle of the secondary scraper 42 is adjusted by the angle adjustment component, thereby adjusting the glue scraping force. This can effectively adapt to decorative paper of different thicknesses or materials, solving the problem of not being able to adapt to decorative paper of different thicknesses or materials.
[0020] Reference Figure 4 This solution does not exclusively limit the specific structure of the angle adjustment component. One feasible solution is as follows: the angle adjustment component includes a worm gear 52 mounted on the rotating shaft 51, and the worm gear 52 is connected to a worm 53. When using this solution, rotating the worm 53 drives the worm gear 52 and the rotating shaft 51 to rotate, thereby precisely fine-tuning the angle of the secondary scraper 42. Due to the self-locking characteristic of the worm gear structure, it can be ensured that the secondary scraper 42 maintains a stable working position after adjustment, effectively avoiding the angle deviation problem caused by equipment vibration or external force interference. Compared with the traditional telescopic rod adjustment method, the worm gear transmission provides higher adjustment accuracy and positional stability, thereby ensuring the consistency of the scraping effect.
[0021] To facilitate the rotation of the worm gear 53, one feasible solution is to connect the worm gear 53 to a knob 54. With this solution, the worm gear 53 can be rotated conveniently and quickly by rotating the knob 54.
[0022] To adjust the position of the secondary scraper 42, one feasible solution is as follows: the adjustment mechanism 5 further includes a distance adjustment component, which includes a bearing 55 connected to the rotating shaft 51. A guide rod 56 is provided on the bracket 21 and passes through the bearing 55. When this solution is adopted, the distance between the secondary scraper 42 and the decorative base paper 3 can be adjusted by moving the bearing 55 along the axial direction of the guide rod 56. The contact pressure and scraping effect of the scraping can be flexibly adjusted according to the characteristics and process requirements of different paper materials. The guide rod 56 provides reliable linear guidance for the movement of the bearing 55, ensuring the stability of the adjustment process.
[0023] To facilitate the fixing of the bearing seat 55, one feasible solution is to install a locking bolt 57 on the bearing seat 55. When this solution is adopted, the bearing seat 55 and the guide rod 56 are fixed by tightening the locking bolt 57.
[0024] To improve the glue application effect, one feasible solution is to use a rigid main scraper 41 and a flexible secondary scraper 42. Specifically, in this embodiment, the main scraper 41 is made of metal, and the secondary scraper 42 is made of rubber or polyurethane. When using this solution, the rigid main scraper 41 can quickly and effectively remove most of the excess glue from the surface of the decorative base paper 3, completing the initial glue application. Subsequently, the flexible secondary scraper 42 performs fine scraping, which can ensure that the glue layer is uniform and flat, and also provide good protection for the paper surface. This effectively avoids the scratches or damage that a traditional single rigid scraper may cause to the paper surface, thus improving the glue application effect.
[0025] The working principle of this embodiment: By rotating knob 54 and moving shaft seat 55, the angle and position of secondary scraper 42 are adjusted to preset values. Decorative base paper 3 enters glue tank 1 smoothly under the continuous traction of glue roller 22. After being fully soaked in glue, it is conveyed upward. First, it passes through rigid main scraper 41 to scrape off most of the excess glue on the surface, completing the initial scraping. Then, the flexible secondary scraper 42 performs fine scraping, thereby achieving precise control of scraping pressure and flexibly adapting to the production needs of decorative paper of different thicknesses and materials. When the secondary scraper 42 is adjusted to the correct position, the self-locking characteristics of the worm gear mechanism and the fixing effect of locking bolt 57 ensure that the secondary scraper 42 remains stable during operation, ensuring both a uniform and flat glue surface and effectively protecting the paper surface from damage.
[0026] To address the issue of being unable to adapt to decorative papers of varying thicknesses or materials, this solution involves continuously feeding the decorative base paper 3 via an impregnation roller 22. The base paper 3 is then immersed in the adhesive solution before being moved upwards. Excess adhesive is subsequently scraped off by the main scraper 41 and the secondary scraper 42. The angle of the secondary scraper 42 is adjusted using an angle adjustment component, thereby regulating the scraping force. This effectively adapts to decorative papers of different thicknesses or materials, resolving the problem of incompatibility with decorative papers of varying thicknesses or materials.
[0027] To ensure consistent glue application, this design incorporates an angle adjustment component including a rotating shaft 51 connected to the secondary scraper 42. A worm gear 52 is mounted on the shaft 51 and connected to a worm 53. Rotating the worm 53 drives the worm gear 52 and the rotating shaft 51 to rotate, thereby precisely fine-tuning the angle of the secondary scraper 42. Due to the self-locking characteristic of the worm gear structure, the secondary scraper 42 maintains a stable working position after adjustment, effectively preventing angle deviation caused by equipment vibration or external interference. Compared to traditional telescopic rod adjustment methods, the worm gear transmission provides higher adjustment accuracy and positional stability, thus ensuring consistent glue application.
[0028] To ensure the stability of the adjustment process of the bearing seat 55, in this scheme, the adjustment mechanism 5 also includes a distance adjustment component. The distance adjustment component includes a bearing seat 55 connected to the rotating shaft 51. A guide rod 56 is provided on the bracket 21 and passes through the bearing seat 55. By moving the bearing seat 55 along the axial direction of the guide rod 56, the distance between the secondary scraper 42 and the decorative base paper 3 can be adjusted. According to the characteristics and process requirements of different paper materials, the contact pressure and scraping effect of the scraper can be flexibly adjusted. The guide rod 56 provides reliable linear guidance for the movement of the bearing seat 55, ensuring the stability of the adjustment process of the bearing seat 55.
