It is used to feed a predetermined amount of plastic pellets into the processing equipment. The plastic pellet quantitative feeder is an efficient and precise plastic processing equipment that can greatly improve production efficiency and product quality, and reduce labor and energy waste.

[0003] There is a plastic granule quantitative feeder in the prior art, which specifically discloses a discharge seat, a discharge barrel is arranged on the upper side of the discharge seat, a drying barrel is arranged on the lower side of the discharge barrel, a lifting cylinder is installed between the left and right sides of the drying barrel and the lower discharge seat, a plurality of fans are installed on the upper side of the drying barrel, and a discharge barrel is installed on the lower side of the drying barrel. The quantitative feeder structure provided by the present invention allows the newly made plastic granules to be passed into the lower drying barrel, and in the process of driving the drying barrel downward, the internal stirring rod structure is driven, and the plurality of fan structures on the upper side of the drying barrel are cooperated to realize the rapid drying of the material in the drying barrel. After the drying barrel moves down a certain distance, the lower left and right discharge plates are driven to rotate vertically, and the dried material in the drying barrel automatically flows out, thereby avoiding the problem of blockage of the plastic granule discharge.

[0004] In the existing plastic particle quantitative feeding devices, most of the quantitative feeding mechanisms have a short intermittent time, so that the quantitatively fed plastic particles do not have enough time to melt, which reduces the quality of the plastic products. Most of the plastic particle quantitative feeding devices do not have a mechanism for stirring the plastic particles, resulting in a large amount of plastic particles piling up and prone to jamming. Summary of the invention

[0005] The object of the present invention is to provide a quantitative conveying device for blow molding material particles, which can effectively solve the above-mentioned technical problems.

[0006] The transmission gear of the present invention is connected with the gear of the transmission gear of the present invention, and the gear of the transmission gear is connected with the gear of the transmission gear of the transmission gear of the transmission gear.

[0007] A driving sprocket is bolted to the rear of the surface of the second rotating rod, and a driven sprocket is bolted to the rear of the surface of the first rotating rod. Chains are meshed on the surfaces of the driven sprocket and the driving sprocket, so that the driving sprocket can transmit the rotational power to the first rotating rod through the driven sprocket, thereby causing the first rotating rod to drive the driving cone wheel to rotate.

[0008] Preferably, rectangular hollow stirring blades are bolted to the upper and lower surfaces of the stirring shaft, so that the stirring shaft can drive the rectangular hollow stirring blades to rotate and stir the material particles in the storage box, thereby preventing the material particles from getting stuck in the discharge chute and being unable to discharge normally.

When the rotating shaft needs to be fixed, the locking rod only needs to be moved, and the locking rod can be pushed to the right by the elastic force of the return spring itself.

[0011] Preferably, locking grooves are provided on the upper and lower sides of the left side of the discharge box, and the inner side of the locking groove is slidably plugged with the right side of the locking rod, so that the locking groove cooperates with the locking rod to fix the rotating shaft to prevent the rotating rod from rotating due to shaking.

[0012] Preferably, a hopper is bolted to the left side of the top of the storage box, so that the user can put the material particles into the storage box through the hopper.
