DETAILED DESCRIPTION

[0020] Embodiment 1

[0021] like Figures 1 to 3 As shown, a sawdust-glue mixing device proposed by the utility model comprises a frame 1, a sealing cover 4 and a discharging piston 7; a rotating table 2 is arranged on the frame 1, a sawdust-glue mixing barrel 3 is arranged on the rotating table 2, the sawdust-glue mixing barrel 3 can be rotated and adjusted along the frame 1 by being driven by the rotating table 2, and a discharging mechanism is arranged on the sawdust-glue mixing barrel 3; the sealing cover 4 is installed on one side of the top of the frame 1 through a lifting mechanism, a stirring mechanism is arranged on the sealing cover 4, and the sealing cover 4 corresponds to the sawdust-glue mixing barrel 3; the discharging piston 7 is installed on the other side of the top of the frame 1 through a lifting mechanism, and the lifting mechanism is set as an electric telescopic rod, and the discharging mechanism and the discharging piston 7 cooperate with each other to quickly discharge the raw materials inside the sawdust-glue mixing barrel 3.

[0022] Furthermore, the rotating platform 2 is composed of a driving mechanism and a mounting seat. The driving mechanism is set as a motor, the motor is installed at the bottom end of the frame 1, and the mounting seat is transmission-connected to the output end of the motor. When the motor is started, it can drive the mounting seat to rotate to any angle.

[0023] Furthermore, a relief valve 6 is provided on the discharge piston 7. After the lifting mechanism drives the discharge piston 7 to slide downward along the inner wall of the sawdust-glue mixing barrel 3 to discharge the material, the relief valve 6 is activated by the controller to balance the internal and external air pressures of the sawdust-glue mixing barrel 3, which is convenient for adjusting the discharge piston 7.

[0024] Further, the discharging mechanism includes an air pump 301, an annular pipe 302, and a sealing box 303; the air pump 301 is installed on the rotating table 2; the annular pipe 302 is installed on the outer wall of the wood chip and glue mixing barrel 3, the air pump 301 is connected to the annular pipe 302 through a hose, and a plurality of groups of air nozzles 304 are evenly arranged on the annular pipe 302. Solenoid valves are arranged on the air nozzles 304 to prevent gas from flowing back under pressure when the discharging piston 7 slides down along the inner wall of the wood chip and glue mixing barrel 3. A plurality of groups of installation openings 305 are provided on the wood chip and glue mixing barrel 3, and the installation openings 305 correspond to the air nozzles 304; a plurality of groups of sealing boxes 303 are provided, and the sealing boxes 303 are installed on the outer wall of the wood chip and glue mixing barrel 3 and correspond to the installation openings 305. The sealing boxes 303 surround the outside of the air nozzles 304, and a sealing door 306 is hinged on the sealing boxes 303, which is convenient for opening the sealing door 306 to repair and replace the air nozzles 304.

[0025] Further, one end of the air nozzle 304 away from the annular pipe 302 is arranged inside the sealing box 303, which will not interfere with the discharging piston 7 sliding down along the inner wall of the wood chip and glue mixing barrel 3, and the air nozzle 304 is arranged obliquely downward relative to the inner wall of the wood chip and glue mixing barrel 3; it is convenient to start the air pump 301 to send air towards the air nozzle 304 to blow the materials attached to the stirring mechanism on the sealing cover 4 downward, so as to avoid splashing and causing pollution and waste.

[0026] In this embodiment, the lifting mechanism drives the sealing cover 4 to move downward until the sealing cover 4 abuts against the top end of the wood chip and glue mixing barrel 3. At the same time, the stirring mechanism is located inside the wood chip and glue mixing barrel 3. Wood chips and glue are added into the wood chip and glue mixing barrel 3 through the feeding port on the sealing cover 4 and the feeding port is closed. The air pump 301 is started to extract the air inside the wood chip and glue mixing barrel 3 through the air nozzle 304 and the annular pipe 302, so that the inside of the wood chip and glue mixing barrel 3 is in a vacuum state. When the stirring mechanism stirs the wood chips and glue, air will not enter the material, so no bubbles will be generated inside the material, improving the stirring efficiency. After the stirring is completed, the air pump 301 is started to blow air into the wood chip and glue mixing barrel 3 along the annular pipe 302 and the air nozzle 304. At the same time, the lifting mechanism drives the stirring mechanism on the sealing cover 4 to move upward. As the stirring mechanism moves upward, the materials on the stirring mechanism are blown downward through the air nozzle 304, thus avoiding a large amount of materials sticking to the stirring mechanism. The rotating table 2 drives the wood chip and glue mixing barrel 3 to rotate away from the sealing cover 4 until the wood chip and glue mixing barrel 3 rotates to the lower part of the discharging piston 7. The lifting mechanism drives the discharging piston 7 to move downward until it fits with the inner wall of the wood chip and glue mixing barrel 3. The air pump 301 is started to input an appropriate amount of air into the wood chip and glue mixing barrel 3 to increase the internal air pressure. As the lifting mechanism drives the discharging piston 7 to continue to move downward, the materials inside the wood chip and glue mixing barrel 3 are discharged through the discharging valve at the bottom end of the wood chip and glue mixing barrel 3. The discharging is more convenient and fast, improving the processing efficiency.

[0027] Embodiment Two

[0028] As Figure 1 and Figure 2 shown, a wood chip mixed glue device proposed by the present utility model, compared with Embodiment 1, a cleaning bucket 5 is arranged at the top of the rotating table 2 and on one side of the wood chip mixed glue bucket 3, and the cleaning bucket 5 corresponds to the discharge piston 7.

[0029] In this embodiment, when the rotating table 2 drives the wood chip mixed glue bucket 3 to rotate below the discharge piston 7, it will also drive the cleaning bucket 5 to rotate below the sealing cover 4 at the same time, so that the sealing cover 4 and the stirring mechanism can be cleaned inside the cleaning bucket 5 to avoid sewage splashing, and the sewage after cleaning can be discharged along the liquid discharge valve at the bottom end of the cleaning bucket 5.

[0030] Embodiment 3

[0031] As Figure 1 , and Figure 2 and Figure 4 shown, a wood chip mixed glue device proposed by the present utility model, compared with Embodiment 2, a cleaning mechanism is arranged on the cleaning bucket 5, and the cleaning mechanism includes a liquid storage tank 501 and a shunt pipe 503; the liquid storage tank 501 is arranged on the rotating table 2, an infusion pump 502 is arranged at the top of the liquid storage tank 501, the shunt pipe 503 is arranged inside the installation box on the outer wall of the cleaning bucket 5, the infusion pump 502 is connected with the shunt pipe 503 through a delivery pipe, and a number of groups of nozzles 504 are arranged on the shunt pipe 503.

[0032] Further, the multiple groups of nozzles 504 on the shunt pipe 503 are divided into upper, middle and lower parts. The output end of the nozzle 504 located above is arranged to incline downward relative to the shunt pipe 503, the output end of the nozzle 504 located in the middle is arranged perpendicular to the shunt pipe 503, and the output end of the nozzle 504 located below is arranged to incline upward relative to the shunt pipe 503, which is convenient for cleaning the stirring mechanism from multiple angles and improving the cleaning efficiency.

[0033] In this embodiment, when the cleaning bucket 5 is driven by the rotating table 2 to rotate below the sealing cover 4, the sealing cover 4 is driven by the lifting mechanism to abut against the top end of the cleaning bucket 5. At this time, the stirring mechanism is located inside the cleaning bucket 5. The cleaning agent in the liquid storage tank 501 is pumped out by the infusion pump 502 and conveyed to the shunt pipe 503, and finally sprayed out by a number of groups of nozzles 504. Through the rotation of the stirring mechanism, the cleaning agent is sprayed out by a number of groups of nozzles 504 towards the stirring mechanism, which can be quickly cleaned and provides convenience for use.
