Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-7 This utility model provides a technical solution: an anti-jamming scraper angle adaptive adjustment device for a decorative paper coating machine, including a support table 1, a decorative paper coating machine body 2, and a coating roller 5. The decorative paper coating machine body 2 is mounted on the upper end of the support table 1. Support blocks 3 are symmetrically arranged on the side of the decorative paper coating machine body 2. A rotating rod 4 is rotatably connected to the support blocks 3. The coating roller 5 is arranged on the side of the rotating rod 4 and is positioned between the two support blocks 3. An angle adjustment mechanism 6 is arranged on the side of the decorative paper coating machine body 2. An anti-jamming mechanism 7 is arranged on the side of the angle adjustment mechanism 6. A distance adjustment mechanism 8 is arranged on the side of the anti-jamming mechanism 7.

[0027] The angle adjustment mechanism 6 includes a connecting column 61, a connecting rod 62, and a limiting bolt 63. Two connecting columns 61 are symmetrically connected to the side of the rotating rod 4. The connecting columns 61 are located on the side of the support block 3. The connecting rod 62 is connected between the two connecting columns 61. The limiting bolt 63 is threadedly connected to the side of the connecting rod 62. The limiting bolt 63 fits against the support block 3. During use, the angle of the scraper body 75 is adjusted according to the actual usage requirements. By rotating the limiting bolt 63, the limiting bolt 63 loses its limitation on the connecting column 61. Then, the connecting column 61 is rotated to adjust the angle of the scraper body 75.

[0028] The anti-jamming mechanism 7 includes a first housing 71, a first sliding rod 72, a first support spring 73, a positioning rod 74, and a scraper body 75. The first housing 71 is symmetrically arranged on the side of the connecting rod 62. The first sliding rod 72 is slidably connected to the inside of the first housing 71. The first support spring 73 is arranged inside the first housing 71. The first sliding rod 72 passes through the side of the first housing 71 and is connected to the positioning rod 74. The scraper body 75 is arranged on the side of the positioning rod 74. The scraper body 75 is positioned between the support block 3 and the coating roller 5. On the side, one end of the first support spring 73 is connected to the inner wall of the first housing 71, and the other end of the first support spring 73 is connected to the side of the first slide rod 72. A second housing 76 is provided on the side of the connecting rod 62. A second slide rod 77 is slidably connected to the inside of the second housing 76. The second slide rod 77 passes through the side of the second housing 76 and is connected to the positioning rod 74. A second support spring 78 is provided inside the second housing 76. A sliding groove 79 is opened at the upper end of the second housing 76. A magnetic block 710 is magnetically connected to the upper end of the sliding groove 79. A switch 711 is connected to the lower end of 710. One end of the second support spring 78 is connected to the inner side wall of the second housing 76, and the other end of the second support spring 78 is connected to the second slide rod 77. The switch 711 is located inside the slide groove 79. During use, the coating on the surface of the decorative paper is evenly scraped by the scraper body 75. At the same time, when the scraper body 75 encounters a protrusion or impurities on the surface of the decorative paper, the scraper body 75 is pushed by the impurities. The scraper body 75 drives the positioning rod 74 to push the first slide rod 72 to slide inside the first housing 71. At the same time, the first slide rod 72 squeezes the first support spring 73 during the sliding process. Meanwhile, the positioning rod 74 pushes the second slide rod 77 to slide inside the second housing 76 during the movement. During the sliding process of the second slide rod 77, it squeezes the second support spring 78. At the same time, the second slide rod 77 triggers the switch 711 during the movement. The switch 711 activates the alarm device to remind the operator, thereby avoiding the situation where impurities affect the operation of the device and cause material jamming.

[0029] The distance adjustment mechanism 8 includes bolts 81, rotating blocks 82, and soft pads 83. Two bolts 81 are symmetrically threaded on the side of the positioning rod 74. The rotating blocks 82 are rotatably connected to the side of the bolts 81, and the soft pads 83 are connected to the side of the rotating blocks 82. The soft pads 83 are in contact with the side of the support block 3. During use, the distance between the doctor blade body 75 and the coating roller 5 can be adjusted as needed to adjust the thickness of the decorative paper coating. When adjustment is needed, the two bolts 81 are rotated, which drives the soft pads 83 to move. The soft pads 83 then contact the support block 3, thereby adjusting the distance between the positioning rod 74 and the coating roller 5, and thus adjusting the position of the doctor blade body 75.

[0030] Working principle: According to Figures 1 to 2During use, the scraper body 75 angle is first adjusted according to actual usage requirements. The limit bolt 63 is rotated, at which point the limit bolt 63 loses its limit on the connecting column 61. Then the connecting column 61 is rotated to adjust the scraper body 75 angle. After the scraper body 75 angle is adjusted, the limit bolt 63 is rotated again to limit the connecting column 61, thus adjusting the angle. The connecting column 61 and the rotating rod 4 are rotatably connected. Therefore, the position limitation of the connecting column 61 does not affect the rotating rod 4 during use.

[0031] according to Figures 3 to 5 During use, the scraper body 75 evenly spreads the coating on the surface of the decorative paper. When the scraper body 75 encounters protrusions or impurities on the surface of the decorative paper, it is pushed by the impurities. The scraper body 75 drives the positioning rod 74 to push the first slide rod 72 to slide inside the first housing 71. At the same time, the first slide rod 72 compresses the first support spring 73 during its sliding. Meanwhile, the positioning rod 74 pushes the second slide rod 77 to slide inside the second housing 76 during its movement. During the sliding of the second slide rod 77, it compresses the second support spring 78. At the same time, the second slide rod 77 triggers the switch 711 during its movement, which activates the alarm device to remind the operator, thus preventing impurities from affecting the operation of the device and causing material jamming. The elastic movement of the scraper body 75 can also prevent damage to the decorative paper when encountering impurities. The magnetic block 710 can adjust the position of the switch 711 according to different needs, so as to improve the applicability of the device.

[0032] according to Figures 6 to 7 During use, the distance between the scraper body 75 and the coating roller 5 can be adjusted according to the thickness of the decorative paper coating. When adjustment is needed, rotate the two bolts 81, which will drive the soft pad 83 to move. The soft pad 83 will then contact the support block 3, thereby adjusting the distance between the positioning rod 74 and the coating roller 5, which in turn will adjust the position of the scraper body 75.

[0033] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
