Description
Technical Field
[0001] This utility model relates to the field of wood-based panel gluing technology, and more specifically, to a uniform mixing mechanism for a particleboard gluing mixer. Background Technology
[0002] In the production of particleboard, gluing is an essential step, and the quality of the gluing process significantly affects important parameters such as the mechanical properties and surface quality of the final particleboard blank. The gluing process is completed by appropriate gluing equipment, which is divided into a pre-mixing process and a post-mixing process. Currently, the gluing equipment on the market uses a horizontal drum mixer for mixing. The particleboard raw materials are fed into the mixer through a feeding device, and then glue is continuously introduced during the mixing process, ensuring thorough mixing of the particleboard raw materials and the glue.
[0003] A search revealed application number CN202211285951.9, entitled "A Uniform Glue Application Process and Equipment for Particleboard." This application addresses the problem that due to the high viscosity of the glue, a long mixing time is required to improve the mixing effect when using a horizontal mixing device, severely impacting the subsequent glue application speed. The solution addresses this by using a vertical rotating rod to drive a centrifugal disc at high speed, allowing the particleboard particles falling from the feed hopper onto the disc to be evenly distributed. During this distribution, the glue is atomized by a first atomizing head on a ring pipe and mixed with the particleboard particles. The mixture is then pre-mixed by the driving action of the vertical rotating rod. The pre-mixed material then enters a horizontal mixing chamber for simultaneous conveying and mixing. The design of the equipment ensures thorough and uniform mixing of materials, significantly shortening the mixing time in the adhesive application process and improving the mixing effect. This effectively guarantees the mechanical properties and surface quality of the boards after subsequent hot pressing. However, in actual use, due to centrifugal force causing the wood shavings to scatter rapidly, the atomized adhesive is difficult to mix thoroughly with the shavings. The bottom mixing device is still required. When the bottom mixing device is in operation, the atomized adhesive is sprayed from top to bottom, only applying adhesive to the shavings at the top. The mixing device cannot quickly turn the shavings at the bottom and middle to the top. Therefore, a long mixing time is still required to achieve the desired results. The work efficiency and adhesive uniformity can be further improved.
[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a uniform mixing mechanism for a particleboard adhesive mixer, which improves the uniformity of mixing and working efficiency, thereby solving the problems mentioned in the background technology.
[0006] To achieve the aforementioned advantages of improved mixing uniformity and work efficiency, the specific technical solution adopted by this utility model is as follows:
[0007] The uniform mixing mechanism of the particleboard adhesive mixer includes a primary mixing chamber and a secondary mixing chamber. The primary mixing chamber is equipped with a first conveyor belt, a second conveyor belt, and a third conveyor belt, which are arranged alternately at equal intervals from top to bottom. A rotating rod is installed above each of the first, second, and third conveyor belts. A material distribution rod is fixedly installed on the surface of each rotating rod. A spray pipe is inserted between the rotating rods inside the primary mixing chamber, and an adhesive application head is connected through the surface of the spray pipe. A discharge port is opened at one end of the bottom surface of the primary mixing chamber, and a feeding channel is connected through the bottom surface of the discharge port. A secondary mixing chamber is connected through the bottom surface of the feeding channel. A stirring motor is fixedly installed on the top surface of the secondary mixing chamber, and a stirring rod is installed at the output end of the stirring motor.
[0008] Furthermore, a glue tank is installed below the primary mixing chamber, and a glue injection pump is fixedly installed on the top surface of the glue tank. The output end of the glue injection pump is connected to a glue delivery pipe, which is connected to the spray pipe through a diverter pipe.
[0009] Furthermore, a drive motor is fixedly installed on the front facade of the primary mixing chamber, and the output end of the drive motor is fixedly connected to one end of the rotating rod.
[0010] Furthermore, a gate valve is installed at the bottom of the secondary mixing chamber, and a feed inlet is provided at one end of the top surface of the primary mixing chamber.
[0011] Furthermore, multiple sets of the stirring motor and stirring rod are arranged at equal angles along the central axis of the secondary mixing chamber.

[0015] Compared with the prior art, this utility model provides a uniform mixing mechanism for a particleboard adhesive mixer, which has the following beneficial effects:
[0016] (1) This utility model adopts a primary mixing chamber. The primary mixing chamber is equipped with a first conveyor belt, a second conveyor belt and a third conveyor belt from top to bottom. When the particleboard is being glued and mixed, the particleboard raw material can be put into the primary mixing chamber from the feed port. The first conveyor belt transports the particleboard raw material. The rotating rod rotates under the drive of the drive motor, which drives the equalizing rod to equalize the material. When the particleboard raw material moves to the bottom of the glue applicator, the glue pump starts and the glue inside the glue box is drawn out and sprayed out along the glue applicator, which is evenly sprayed onto the surface of the particleboard raw material. As the equalizing rod rotates continuously, the raw material is continuously mixed. The first conveyor belt, the second conveyor belt and the third conveyor belt are arranged in an alternating manner. The raw material is continuously turned over when it falls, thereby completing continuous turning and mixing. The glue applicator is dispersed. The raw material is evenly spread out under the equalizing rod and fully and quickly mixed with the glue sprayed from the glue applicator, thereby improving the mixing efficiency and the working efficiency.
[0017] (2) This utility model adopts a two-stage mixing chamber. The raw materials after being mixed in the primary mixing chamber enter the secondary mixing chamber. The stirring motor drives the stirring rod to rotate, and the raw materials after the initial mixing are stirred and mixed a second time, which further improves the uniformity of mixing and working efficiency.

The first conveyor belt 2 transports the raw materials, and the rotating rod 6, driven by the drive motor 19, rotates, causing the equalizing rod 7 to evenly distribute the material. When the particleboard raw materials move below the application head 9, the glue pump 17 starts, drawing glue from the glue tank 16 and spraying it evenly onto the surface of the particleboard raw materials along the application head 9. As the equalizing rod 7 continues to rotate, the raw materials are continuously mixed.
