Description

Technical Field

[0001] This utility model relates to the field of adhesive proportioning technology, specifically to an adhesive proportioning device for fiberboard production. Background Technology

[0002] In the fiberboard production process, adhesive is a crucial bonding material, and its quality directly affects the strength, durability, and surface finish of the fiberboard. However, air can easily get into the adhesive during production and use, forming bubbles. If these bubbles are not effectively removed, they can cause defects during the fiberboard forming process, such as weak adhesion in certain areas and uneven surfaces, seriously affecting product quality.

[0003] Traditional methods for defoaming adhesives mainly include static defoaming, mechanical stirring defoaming, and vacuum defoaming. Static defoaming mainly involves allowing bubbles to rise and burst naturally over a long period of time. While simple, this method is time-consuming, inefficient, and unsuitable for large-scale production. Mechanical stirring defoaming uses a stirring device to agitate the adhesive, causing bubbles to burst. However, stirring alone is insufficient to completely remove tiny bubbles, and new bubbles may be introduced during the process. Vacuum defoaming uses vacuum equipment to evacuate the adhesive, creating a negative pressure environment that causes bubbles to expand and burst. While this method is effective, for high-viscosity adhesives, the bubbles rise slowly, and the defoaming efficiency still needs improvement. Utility Model Content

[0005] To achieve this objective, the present invention adopts the following technical solution:

[0006] A glue mixing device for fiberboard production includes a mixing tank. A positioning ring is installed on the bottom side wall of the mixing tank. The outer wall of the positioning ring has evenly distributed fixing openings. An upper cylinder with its opening facing downwards is installed on the inner wall of the fixing openings. A lower cylinder with its opening facing upwards is provided at the bottom of the upper cylinder. A vibration spring is installed on the inner wall of the upper cylinder.

[0028] Specifically, in this embodiment, a positioning ring 2 is installed on the bottom side wall of the mixing tank 1. The outer wall of the positioning ring 2 has equidistantly distributed fixing openings. An upper cylinder 3 with its opening facing downwards is installed inside the fixing openings. The bottom of the upper cylinder 3 has a lower cylinder 4 with its opening facing upwards. The two are connected by a vibration spring 5. The bottom outer wall of the vibration spring 5 is connected to the inner wall of the lower cylinder 4 to form a vibration system. The vibration motor 16 is fixed at the center of the bottom of the mixing tank 1. When the vibration motor 16 is started, it drives the upper cylinder 3 and the lower cylinder 4 to vibrate through the vibration spring 5, thereby vibrating and defoaming the glue in the mixing tank 1. An air pump 14 is installed on the top outer wall of the mixing tank 1. Its output end is connected to the inside of the mixing tank 1 through a pipe. The air pump 14 is used to evacuate the mixing tank 1 during the mixing process to form a negative pressure environment, which facilitates the intake and defoaming of the glue raw materials. A pressure gauge 15 is installed on the top of the mixing tank 1 and can monitor the pressure changes inside the mixing tank 1.

[0029] The motor 11 is installed at the top center of the mixing tank 1. Its output end passes through the top outer wall of the mixing tank 1. A stirring rod 12 is fixedly installed through a coupling. The outer wall of the stirring rod 12 is equipped with stirring blades 13 that are evenly distributed for uniformly stirring the glue. The motor 11 drives the stirring rod 12 and stirring blades 13 to rotate, so that the glue raw materials are fully mixed. The motor fixing cover 10 is fixed to the top outer wall of the mixing tank 1 to protect the motor 11 and prevent external dust from entering.

[0030] The feed pipe 17 is installed on the top side of the outer wall of the mixing tank 1 to draw the glue raw material into the mixing tank 1. A valve 19 is installed on the feed pipe 17 to control the inflow of raw material. The discharge pipe 18 is installed on the bottom side of the mixing tank 1 to discharge the mixed glue. A valve 19 is also installed on the discharge pipe 18 to control the outflow of glue. One end of the feed pipe 17 and the discharge pipe 18 is fixed with a pipe joint 20 for easy connection with other equipment or pipelines.

[0031] Working principle and usage process of this utility model:

[0032] When using this glue mixing device for fiberboard production, first open valve 19 on feed pipe 17, start air pump 14 to create a vacuum in mixing tank 1, forming a negative pressure environment, and suck the glue raw material into mixing tank 1 through feed pipe 17. Start motor 11 to drive stirring rod 12 and stirring blade 13 to rotate, and stir the glue evenly. At the same time, start vibration motor 16, and drive upper cylinder 3 and lower cylinder 4 to vibrate through vibration spring 5. Combined with the vacuum function of air pump 14, the air pump effectively removes air bubbles in the glue. After stirring is completed, turn off motor 11 and vibration motor 16, open valve 19 on discharge pipe 18, start air pump 14 to form high pressure, and force the glue in mixing tank 1 out through discharge pipe 18.

[0033] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
