Description

Technical Field

[0001] This utility model belongs to the field of decorative base paper production technology, specifically relating to a spraying device for decorative paper production. Background Technology

[0002] The decorative paper production spraying device is a spraying equipment specifically used in the decorative paper production process. Its main function is to spray coating evenly onto the surface of the decorative paper to achieve the purpose of beautification, protection and performance enhancement.

[0003] Decorative paper production spraying equipment typically consists of a main body, a sprayer body, moving parts, and a drive unit. The main body is the core structure of the equipment, used to support and fix the other components. The sprayer body is the core component of the spraying operation, responsible for spraying the paint in an atomized form. The moving parts and drive unit are used to adjust the position of the sprayer body to adjust the spraying position according to actual needs.

[0004] A significant problem with spray coating equipment when applying coatings to decorative paper is uneven coating. This often results in some areas of the decorative paper having excessively thick coating, while other areas may have insufficient coating. This significant difference in localized coating thickness further leads to uneven overall thickness of the decorative paper, affecting not only its aesthetics but also potentially its physical properties and service life.

[0005] Specifically, areas with excessively thick paint may develop cracks or peeling due to uneven drying or poor curing, while areas with insufficient paint may fail to achieve the desired decorative or protective effect. Utility Model Content

[0006] The purpose of this invention is to provide a spraying device for decorative paper production, which aims to solve the problem of uneven spraying in the existing technology. This phenomenon often leads to excessively thick coating in some areas of the decorative paper surface, while other areas may have insufficient coating. This significant difference in local coating thickness will further cause uneven overall thickness of the decorative paper, which not only affects the aesthetics of the decorative paper, but may also have an adverse effect on its physical properties and service life.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a decorative paper production spraying device, including a spraying table, a conveyor roller mounted on the surface of the spraying table, a decorative paper strip inserted through the side surface of the conveyor roller, and a spraying mechanism mounted on the surface of the spraying table; a first guide rod connected to the surface of the spraying table, a horizontal plate connected to the top of the first guide rod, a telescopic rod mounted on the surface of the horizontal plate, a scraper connected to the end of the telescopic rod, a guide sleeve connected to the side surface of the scraper sleeved on the surface of the first guide rod, a liquid guide plate connected to the side surface of the scraper, and a liquid guide groove formed on the surface of the liquid guide plate.

[0008] In a preferred embodiment of the decorative paper production spraying device of this utility model, the first guide rod and the guide sleeve are symmetrically arranged on both sides of the scraper, and the guide sleeve and the first guide rod are slidably connected.

[0009] In a preferred embodiment of the decorative paper production spraying device of this utility model, the scraper and the telescopic rod form a telescopic structure.

[0010] As a preferred embodiment of the decorative paper production spraying device of this utility model, the surface of the spraying table is connected to a bracket, the surface of the bracket is provided with a guide hole, a second guide rod passes through the inside of the guide hole, a spring strip is connected between the second guide rod and the spraying table, a movable frame is connected to the top of the second guide rod, a bearing is fitted on the side surface of the movable frame, a rotating shaft passes through the inside of the bearing, and a guide wheel is connected to the surface of the rotating shaft.

[0011] In a preferred embodiment of the decorative paper production spraying device of this utility model, the second guide rod is slidably connected to the bracket through the guide hole, and the second guide rod and the spring strip form an elastic telescopic structure.

[0012] In a preferred embodiment of the decorative paper production spraying device of this utility model, the rotating shaft is configured into a rotating structure with the movable frame via bearings.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, when the telescopic rod extends, it can drive the scraper to move downwards. The downward movement of the scraper can drive the liquid guide plate to move downwards. When the liquid guide plate moves downwards to the surface of the decorative paper tape, the coating on the surface of the decorative paper tape can be evenly scraped and smoothed by the liquid guide plate. Excess coating can enter the liquid guide groove from the surface of the liquid guide plate. The coating inside the liquid guide groove can flow out from both ends. This can avoid uneven coating of the decorative paper tape, which would lead to uneven thickness of the subsequent finished product.

[0015] In this invention, the spring strip can compress the second guide rod through its own elasticity. When the second guide rod is compressed, it can drive the movable frame to move upward. The upward movement of the movable frame can drive the guide wheel to move upward through the bearing and the rotating shaft. When the elasticity of the spring strip and the squeezing force of the decorative paper strip on the guide wheel are balanced, the guide wheel can tension and guide the decorative paper strip, thereby avoiding deformation and curling of the decorative paper strip after spraying, thus improving the quality of the finished product.

[0026] In practical use, when the scraper 8 is subjected to a force, it can drive the guide sleeve 9 to slide on the surface of the first guide rod 5, which can limit the movement direction of the scraper 8.

[0027] Preferably, the scraper 8 and the telescopic rod 7 form a telescopic structure.

[0028] In practical use, when the telescopic rod 7 extends, it can drive the scraper 8 to move downward. When the scraper 8 drives the liquid guide plate 10 to move downward to the surface of the decorative paper tape 3, the coating on the surface of the decorative paper tape 3 can be evenly scraped and smoothed by the liquid guide plate 10.

[0029] Preferably, a bracket 12 is connected to the surface of the spraying station 1, a guide hole 13 is opened on the surface of the bracket 12, a second guide rod 14 passes through the inside of the guide hole 13, a spring strip 15 is connected between the second guide rod 14 and the spraying station 1, a movable frame 16 is connected to the top of the second guide rod 14, a bearing 17 is fitted on the side surface of the movable frame 16, a rotating shaft 18 is connected through the inside of the bearing 17, and a guide wheel 19 is connected to the surface of the rotating shaft 18.

[0030] Preferably, the second guide rod 14 is slidably connected to the bracket 12 through the guide hole 13, and the second guide rod 14 and the spring strip 15 form an elastic telescopic structure.

[0031] In practical use, the movable frame 16 is subjected to a force that can drive the second guide rod 14 to slide inside the guide hole 13, which can limit the movement direction of the movable frame 16.

[0032] Preferably, the rotating shaft 18 forms a rotating structure with the movable frame 16 via the bearing 17.

[0033] In practical use, when the guide wheel 19 is subjected to a force, it can drive the rotating shaft 18 to rotate inside the bearing 17.

[0034] Working principle: When using this decorative paper spraying device, firstly, the decorative paper strip 3 is passed through the conveyor rollers 2.
