[0003] In the related art, a raw material stirring device for a blow molding machine includes a stirring barrel and a feed port arranged on the top of the stirring barrel. Raw material particles (such as resin particles, masterbatch, additives, etc.) enter the stirring barrel from the feed port. A driving motor is installed on the stirring barrel. A rotating shaft fixedly connected to the driving shaft of the driving motor is rotatably installed in the stirring barrel. A stirring rod is fixedly installed on the rotating shaft. The driving motor drives the stirring rod to rotate through the rotating shaft, thereby stirring and mixing a variety of raw material particles; a discharge pipe connected to the feed end of the blow molding machine is installed at the bottom of the stirring barrel to facilitate the mixed raw material particles to be fed into the blow molding machine.

[0004] Regarding the above-mentioned related technologies, it is difficult to fully mix the various raw material particles by simply using a stirring rod to stir the various raw material particles. Insufficient mixing of the various raw material particles will affect the quality of the film product, so it needs to be improved. Summary of the Invention

[0007] By adopting the above technical solution, the stirring component stirs and mixes the material put into the stirring barrel, and the transparent plate at the observation port facilitates observation of the stirring condition of the material inside the stirring barrel. When the stirring uniformity of the material inside the stirring barrel is poor, the return valve and the return pipe are opened to discharge the material, and the discharged material is reintroduced into the top of the stirring barrel through the return port through the transfer component to facilitate re-stirring and mixing of the material, thereby improving the uniformity of the stirring and mixing of the material.

[0008] Preferably, the stirring assembly includes a stirring shaft, a stirring blade, a stirring rod and a stirring motor; the stirring shaft is rotatably arranged on the stirring barrel, the stirring blade is arranged on the stirring shaft, and the stirring blade is spirally extended along the length direction of the stirring shaft; the stirring rod is arranged between the stirring shaft and the stirring blade, and the stirring motor is arranged on the stirring barrel to drive the stirring shaft to rotate.

[0012] Preferably, an observation panel is embedded on the side wall of the transfer box, and a shock assembly for shocking the transfer box is provided on the transfer box.

[0013] By adopting the above technical solution, the observation plate makes it easy for users to observe the materials inside the transfer box, so as to know the transfer status of the materials inside the transfer box by the transfer parts; the shock assembly shocks the transfer box, reducing the phenomenon of materials adhering to the inner wall of the transfer box and making it difficult to pump and transfer, thereby ensuring the recycling and mixing utilization rate of the materials.

[0015] By adopting the above technical solution, the driving member drives the shock block away from the transfer box and causes the torsion member to undergo elastic deformation. Then the torsion member uses its own torque to drive the rotating arm to drive the shock block close to the transfer box, and causes the shock block to shock the transfer box.

[0016] Preferably, the driving member includes a mounting cover, a driving shaft, a windshield, an extension frame and a driving block; the mounting cover is connected and arranged between the transfer box and the suction pipe, the driving shaft is rotatably passed through the mounting cover, the windshield is arranged on the peripheral wall of the driving shaft, and the windshields are spaced apart along the circumference of the driving shaft to shield the connection between the suction pipe and the mounting cover; the extension frame is arranged outside the transfer box, and the extension frame is connected to the end of the driving shaft; the driving block is arranged on the extension frame, and the side wall of the driving block is provided with a lifting slope for lifting the shock block.

[0017] By adopting the above technical solution, the transfer member and the suction pipe suck the material inside the transfer box, and the suction force generated by the suction pipe and the material hit the windshield during the movement, so that the windshield drives the drive shaft to rotate, and the drive shaft drives the extension frame and the drive block to rotate, and the lifting inclined surface is used to lift the shock block; In addition, the positions of the mounting cover, the drive shaft, the windshield and the suction pipe are coordinated so that the suction pipe is located on the windshield on one side of the drive shaft, so that the suction force provided by the suction pipe is concentrated on the windshield on one side of the drive shaft, thereby facilitating the windshield to drive the drive shaft to rotate.

[0018] Preferably, the mixing barrel is provided with a mixing cylinder at the return port, and the mixing cylinder is connected to the delivery pipe; a mixing component for mixing materials is provided inside the mixing cylinder.

[0024] Secondly, The present application provides a method for using a raw material stirring and mixing device for a film blowing machine, comprising the following steps: Stirring: The stirring component stirs and mixes the materials inside the mixing barrel; Observation: Observe the mixing status of materials inside the mixing barrel through the transparent plate at the observation port; Return material: open the return valve, and the material that is not mixed evenly at the bottom of the mixing barrel will be reintroduced into the mixing barrel through the return pipe and transfer assembly for mixing; Discharging: After stirring is completed, open the discharge valve and the stirred material will be discharged through the discharge pipe.

[0046] The user observes the stirring condition of the material inside the mixing barrel 1 through the transparent plate 131. If it is found that the stirring uniformity of the material inside the mixing barrel 1 is poor, the user opens the return valve 141, so that the material inside the mixing barrel 1 flows into the transfer box 31 through the return pipe 14, and the material inside the transfer box 31 is re-injected into the mixing barrel 1 through the return port 15 through the transfer member 34 for stirring, thereby improving the uniformity of the material stirring.
