[0001] This utility model relates to the technical field of decorative paper coating machine, and in particular to a segmented scraper adjustment device for decorative paper coating machine. Background Technology

[0002] A decorative paper coating machine is a device specifically designed to evenly apply adhesive to the surface of decorative paper. It is widely used in the field of artificial board veneer processing. The scraper, as a key component in the coating process, is mainly used to control the thickness and uniformity of the adhesive on the paper surface. Through the relative movement between the scraper and the glue roller, excess adhesive is scraped off, ensuring that the coating layer is neither too thick, affecting drying efficiency and performance, nor too thin, leading to poor adhesion or glue smearing.

[0003] The existing scraper installation method is complicated, requiring the disassembly of multiple parts for adjustment and replacement, which is cumbersome. At the same time, the frequent replacement operations increase downtime and maintenance costs, resulting in poor overall practical effect.

[0004] Therefore, in response to the problems of complex and cumbersome scraper installation methods mentioned above, this utility model adopts a sliding scraper installation method to simplify the installation and disassembly process of the scraper. Compared with the traditional manual adjustment method, this device can effectively avoid uneven glue layer, improve the accuracy of adjustment, and make the glue application effect more stable and uniform.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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 1-8This utility model provides a technical solution: a segmented scraper adjustment device for a decorative paper coating machine, including a protective outer frame 1, a strip mounting base 2 and a scraper body 3. The strip mounting base 2 is slidably installed inside the protective outer frame 1. The scraper body 3 is provided in three sets, with the side outer walls of two adjacent sets of scraper bodies 3 fitting together, and all three sets of scraper bodies 3 are installed below the strip mounting base 2.

[0027] A positioning and installation mechanism 4 is provided above the protective frame 1. An abutment and limiting mechanism 5 is installed between the strip mounting base 2 and the scraper body 3. An auxiliary assembly mechanism 6 is installed between the protective frame 1 and the strip mounting base 2.

[0028] The positioning and installation mechanism 4 includes positioning ear plates 401, columns 402, and reinforcing support frames 403. Positioning ear plates 401 are symmetrically fixedly installed on the top outer wall of the protective frame 1. Columns 402 are fixedly installed on the top outer wall of the protective frame 1 at the middle section. Reinforcing support frames 403 are symmetrically connected to the top outer wall of the columns 402. The bottom end of the reinforcing support frames 403 is connected to the top outer wall of the protective frame 1. Both sets of reinforcing support frames 403 are installed with an inclined structure. The setting of columns 402 and two sets of reinforcing support frames 403 here has a reinforcing and supporting effect on the overall structure of the device.

[0029] The contact limiting mechanism 5 includes a positioning block 501, a contact groove 502, a positioning slide groove 503, a cylindrical groove 504, a contact pin 505, and a contact spring 506. The positioning block 501 is fixedly installed on the top outer wall of the scraper body 3. The side outer wall of the positioning block 501 has a contact groove 502. The side outer wall of the strip-shaped mounting base 2 has three sets of positioning slide grooves 503 for sliding installation of the positioning block 501. The inner side wall of the strip-shaped mounting base 2 at the position of the positioning slide groove 503 has a through cylindrical groove 504. The contact pin 505 is slidably installed inside the cylindrical groove 504, and the contact pin 505 is engaged with the contact groove 502. The outer side wall of the contact pin 505 and the inner wall of the bottom of the cylindrical groove 504 are... A contact spring 506 is installed between the two parts. The top and bottom outer walls of the contact pin 505 are symmetrically provided with limit sliders 507. The inside of the strip mounting base 2 is provided with a limit groove 508 for the limit slider 507 to slide. The internal space of the cylindrical groove 504 and the limit groove 508 are connected. A slide rod 509 is fixedly installed on the side outer wall of the contact pin 505. The sliding end of the slide rod 509 is located on the outside of the strip mounting base 2. The positioning block 501 is set as an inverted "L" shaped structure. The contact surfaces of the positioning block 501 and the contact pin 505 are both set as arc-shaped structures. The design of the contact surfaces of the positioning block 501 and the contact pin 505 being set as arc-shaped structures allows them to move relative to each other when they are in contact.

[0030] The auxiliary assembly mechanism 6 includes a first threaded groove 601, a second threaded groove 602, and a fastening bolt 603. The first threaded groove 601 is symmetrically opened through the outer walls on both sides of the protective frame 1. The second threaded groove 602 is opened in alignment on the outer walls on both sides of the strip mounting base 2. The fastening bolt 603 is installed inside the first threaded groove 601 and the second threaded groove 602, and the fastening bolt 603 is embedded inside the protective frame 1.

[0031] Working principle: According to Figures 1-3 As shown, the positioning ear plate 401 is designed to facilitate the use of bolt assemblies to position and install the entire device into the interior of the decorative paper coating machine in subsequent installation processes. The specific fastening and installation methods are not described in detail here, as they are existing conventional operating techniques.

[0032] according to Figures 4-7 As shown, when the scraper body 3 needs to be installed inside the strip mounting base 2, the scraper body 3 first needs to be adjusted to a suitable position, and then the positioning block 501 at its upper end needs to be pushed into the corresponding positioning groove 503. When the positioning block 501 abuts against the contact pin 505 during the movement, the contact pin 505 automatically moves to the side under the pressure of the positioning block 501, providing a certain space for the positioning block 501 to pass through. Then, the contact pin 505 retracts into the cylindrical groove 504. When the contact pin 505 moves, it will also automatically drive the limiting slider 507 to slide inside the limiting groove 508. Here, the limiting slider 507 and The setting of the limiting slide groove 508 plays a limiting and supporting role in the movement trajectory of the abutment post 505. At the same time, the abutment spring 506 is in a contracted state under the squeezing action of the abutment post 505. When the positioning block 501 moves to the bottom of the positioning slide groove 503, the installation position of the abutment post 505 and the abutment groove 502 are correspondingly coincident. Then, the reaction force generated by the squeezing of the abutment spring 506 will automatically push the abutment post 505 out and make it lock into the interior of the abutment groove 502. In this way, the positioning block 501 can be firmly positioned inside the strip mounting base 2 by the insertion and abutment action of the abutment post 505, thereby simultaneously completing the installation process of the scraper body 3.

[0033] When the scraper body 3 needs to be removed from the strip mounting base 2 during subsequent use, the slide bar 509 needs to be moved first. The slide bar 509 will then move and automatically pull the abutment pin 505 out of the abutment slot 502. Then the positioning block 501 will change from the locked state to the active state, and the scraper body 3 can be directly removed from the strip mounting base 2.

[0034] according to Figure 8As shown, when it is necessary to install the strip mounting base 2 into the interior of the protective frame 1, the strip mounting base 2 should first be pushed into the interior of the protective frame 1 from bottom to top. When the strip mounting base 2 moves to the top of the protective frame 1, the installation positions of the first threaded groove 601 and the second threaded groove 602 will coincide. Then, the fastening bolt 603 can be directly screwed through the first threaded groove 601 to the bottom of the second threaded groove 602 to complete the locking and installation process of the protective frame 1 and the strip mounting base 2.

[0035] 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.

[0036] 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.
