Description

Technical Field

[0001] The utility model relates to the technical field of wood shaving glue applicators, in particular to a uniform speed quantitative wood shaving glue applicator. Background Art

[0002] Particleboard is a board made of wood shavings bonded with adhesive, also known as particleboard. Usually, a particleboard machine is used to plane the wood into thin slices, which are then hot-pressed and glued together. Particleboard has excellent performance and usage characteristics and is widely used in furniture manufacturing, building decoration, packaging boxes and other fields. During the production and processing of particleboard, a glue applicator is required to apply and stir the glue so that the glue and wood shavings are fully mixed.

[0003] For example, announcement number: CN207415598U discloses "a particleboard particle glue applicator" including a glue applicator housing, an inner cavity of the glue applicator housing having a stirring shaft transversely mounted thereon via a transmission bearing, and the stirring shaft penetrates the glue applicator housing, a stirring device is evenly fixed on the outer wall of the stirring shaft, and the stirring device is arranged in the inner cavity of the glue applicator housing.

[0004] However, in the prior art, during the gluing process of the wood chip glue applicator, a glue supply pump and a glue injection tube are used to supply material to the inside of the glue injection head, and glue is injected into the surface of the wood chip through the glue injection head. When the mixing process has a precise requirement for the amount of glue added at one time, the existing glue applicator needs to use a high-precision glue supply pump to complete the glue supply operation. It is difficult for the glue applicator to achieve uniform and quantitative glue application through its own glue application structure. Since the high-precision glue supply pump equipment cost is relatively high, the production cost of the glue applicator will increase, which is not conducive to reducing the production cost of particleboard. Utility Model Content

Since the cost of high-precision glue supply pump equipment is relatively high, the production cost of the glue applicator will increase, which is not conducive to reducing the production cost of particleboard. A uniform-speed quantitative particle glue applicator is proposed.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a uniform-speed quantitative wood chip glue applicator, comprising a fixed frame, a stirring mechanism is fixedly connected to the upper part of the fixed frame, a quantitative glue discharging mechanism is fixedly connected to the upper part of the stirring mechanism, a driving mechanism is fixedly connected to one side of the quantitative glue discharging mechanism, and the driving mechanism is fixedly connected to the upper part of the fixed frame;

[0010] Preferably, the quantitative glue discharging mechanism includes two electro-hydraulic push rods, and the two electro-hydraulic push rods are symmetrically distributed at both ends of the stirring mechanism.

[0011] Preferably, a No. 1 connecting plate is slidably connected to the upper portion of the electro-hydraulic push rod, a No. 2 connecting frame is rotatably connected to the upper portion of the No. 1 connecting plate, and the No. 2 connecting frame is fixedly connected to the end of the No. 2 guide rail.

[0013] Preferably, a glue injection head is installed at the lower part of the upper glue tube, and a valve is installed on the surface of the glue injection head.

[0014] Compared with the prior art, the advantages and positive effects of the utility model are:

[0015] 1. In the utility model, when the electro-hydraulic push rod adjusts the end height of the No. 2 guide rail, the No. 2 connecting frame rotates along the No. 1 connecting plate to adjust the inclination angle of the No. 2 guide rail, thereby adjusting the height difference of the stroke when the No. 2 slider slides from the high end to the low end of the No. 2 guide rail. The height of the moving stroke is the displacement of the piston along the upper rubber tube pushed by the connecting rod, that is, the amount of glue discharged by the glue inside the upper rubber tube pushed by the piston. By adjusting the height difference at both ends of the No. 2 guide rail, the glue output can be accurately adjusted, which is convenient for adjusting the glue output while reducing equipment costs.

[0016] 2. In the utility model, the servo motor drives the screw rod to rotate, thereby driving the moving block to move, and the moving block drives the connecting block and the upper glue tube to move.

At the same time, the upper glue tube moves at a uniform speed along the upper part of the stirring mechanism, and the surface of the raw material placed inside the stirring mechanism is evenly glued, which is convenient for the stirring mechanism to quickly and fully stir the raw materials.
