Description

Technical Field

[0001] The utility model belongs to the technical field of fiberboard processing, in particular to a fiberboard gluing device. Background Art

[0002] In the production process of fiberboard, gluing is a very important process, which determines the uniformity and strength of the bonding of fiberboard raw materials and is the most important factor affecting the quality of fiberboard. Gluing operation is an indispensable stage in the production process of medium-density fiberboard.

[0003] In the existing fiberboard gluing operation, the glue is adjusted according to a certain ratio, and the paraffin is heated and melted, and then the prepared glue and paraffin are sprayed onto the fiber through a gluing device. However, during the spraying process, if the amount of glue applied is too large, the fiberboard will be too thickly glued. At the same time, too fast gluing speed, improper gluing distance or too high viscosity of the glue may lead to uneven gluing and form an overly thick glue layer. Too thick glue will lead to uneven glue layer on the surface of the fiberboard, and the thickness of the glue layer may be inconsistent, affecting the quality and appearance of the fiberboard. Too thick glue will also increase the amount of glue used, resulting in increased production costs. Utility Model Content

An auxiliary component 5 is provided on the mounting frame 2.

[0032] The auxiliary component 5 includes a mounting seat 51 fixedly mounted on the upper surface of the mounting frame 2. The mounting seat 51 is frame-shaped. An orientation block is fixedly connected to the inner side wall of the mounting seat 51. The number of orientation blocks is two and they are symmetrically distributed. A driving motor 52 is fixedly mounted on the side of the mounting seat 51. A gear 53 is fixedly connected to the output end of the driving motor 52. A connecting column 54 that passes through the mounting frame 2 is movably connected to the inner side of the mounting seat 51. The connecting column 54 is located on the inner side of the through hole. An orientation groove is provided on the outer side of the connecting column 54. One end of the orientation block is located on the inner side of the orientation groove. The orientation block cooperates with the orientation groove so that the connecting column 54 can stably perform lifting operations.

[0033] The side of the connecting column 54 is fixedly connected with a rack 55 meshing with the gear 53, and the lower end of the connecting column 54 is fixedly connected with a connecting plate 56, the connecting plate 56 is parallel to the glue-applying device 4, the length of the connecting plate 56 is adapted to the length of the inner wall of the mounting frame 2, the connecting plate 56 is trapezoidal, the connecting plate 56 is located on the inner side of the mounting frame 2, and the lower end of the connecting plate 56 is provided with a movable groove 561;

[0034] A laser distance measuring sensor 562 is fixedly connected to the outer side of the connecting plate 56.

[0035] A scraper 57 is movably connected to the inner side of the connecting plate 56, and the scraper 57 is located on the inner side of the movable groove 561. A rubber strip 571 is fixedly connected to one end of the scraper 57 located on the outer side of the movable groove 561.

An adjusting member 58 is provided between the scraper 57 and the connecting plate 56, and the adjusting member 58 includes an electric motor 581 fixedly mounted on the upper surface of the connecting plate 56, and the electric motor 581 is located in the middle position of the connecting plate 56.

[0036] The cooperation between the screw and the thread groove 582 583 can be adjusted at the millimeter level. This adjustment depends on the accuracy and fineness of the thread. When the screw rotates in the thread groove 582 583, due to the spiral structure of the thread, the screw 582 will move along the axial direction of the thread groove 583. By accurately controlling the rotation angle and number of turns of the screw 582, millimeter-level fine-tuning can be achieved. This adjustment method is widely used in the fields of machinery, electronics, and automation to accurately control parameters such as the position, height or angle of the equipment. It should be noted that the specific adjustment accuracy depends on the design, processing accuracy and matching method of the thread. Therefore, in practical applications, it is necessary to select appropriate thread specifications and matching methods to achieve the required adjustment accuracy.

[0037] The working principle of the above embodiment is:

[0038] When it is necessary to glue the fiberboard, measure the thickness of the fiberboard, start the hydraulic cylinder 3, adjust the glue device 4 to a suitable height, and start the drive motor 52 at the same time. The drive motor 52 drives the gear 53 to rotate. Under the cooperation of the orientation seat and the orientation groove, the rack 55 meshing with the gear 53 drives the connecting plate 56 on the connecting column 54 to adjust the height so that the connecting plate 56 meets the processing height of the fiberboard. When the connecting plate 56 is adjusted in height, the distance can be measured by the laser distance sensor 562. After the measurement, the fiberboard is placed on the roller conveyor 1 and started. The electric motor 581 drives the screw 582 to rotate. Through the restriction of the movable groove 561, the scraper 57 connected by the threaded groove 583 can be precisely adjusted so that the distance between the rubber strip 571 and the fiberboard is between 1-3 mm. After the adjustment is completed, the glue application device 4 is started so that the nozzle on the glue application device 4 sprays glue on the fiberboard. As the roller conveyor 1 drives the fiberboard to move, the scraper 57 scrapes off the thicker glue layer on the surface of the fiberboard, and the scraped glue drips into the collection box 101 through the gap between the rollers of the roller conveyor 1.

[0039] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
