[0001] The utility model relates to the technical field of particleboard, in particular to a chip mixing and gluing device for particleboard production. Background Technique
[0002] The role of wood chips is relatively extensive. After being crushed, high-pressure wood boards can be made. The high-pressure boards made of wood chips and sawdust are widely used in the production of furniture products. Particleboard, also known as particle board, is made by cutting various branches, small-diameter logs, fast-growing wood, sawdust, etc. into fragments of a certain specification, and then drying, mixing with sizing agents, hardeners, waterproofing agents, etc., and pressing into a kind of artificial board under a certain temperature and pressure. The particles are unevenly arranged. During the production and processing of particleboard, a stirring device is often needed to evenly stir the wood chip scraps and glue to ensure the quality of particleboard production.
[0003] However, some existing stirring devices do not have the function of pre-crushing, and at the same time, the mixing efficiency of wood chips and sizing agents is relatively low. Some of the wood chips and sizing agents inside cannot be fully contacted, and the mixing effect is poor, thus affecting the quality of particleboard. For this reason, we propose a chip mixing and gluing device for particleboard production to solve the above problems. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a chip mixing and gluing device for particleboard production to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A chip mixing and gluing device for particleboard production, including a bottom plate and a gluing box body. The upper left part of the gluing box body is fixedly connected with a pre-crushing box body. Between the front and rear inner walls of the pre-crushing box body, two crushing rollers are rotatably connected. The two crushing rollers cooperate to crush larger wood chips. Between the upper and lower inner walls of the gluing box body, a main shaft is rotatably connected. The main shaft is hollow. There are two cross bars on both sides of the main shaft.

[0008] Further preferably, the cross bar is rotatably connected to the protective housing through a bearing. One ends of the two cross bars close to each other are fixedly connected with a first bevel gear, and the first bevel gear meshes with a second bevel gear.
[0009] Further preferably, the glue mixing box body is fixedly connected to the top of the bottom plate through four support legs, and a material box and a water pump are fixedly connected to the top of the bottom plate.
[0010] Further preferably, the water inlet of the water pump extends into the material box, the water outlet of the water pump is communicated with a connecting pipe, and the connecting pipe is communicated with the main shaft through a rotary joint.
[0011] Further preferably, a second motor is fixedly connected to the front side of the glue mixing box body.
