Description

Technical Field

[0001] The utility model relates to a feed preheating mechanism, in particular to a feed preheating mechanism for processing plastic tableware, and belongs to the technical field of plastic tableware processing. Background Art

[0002] In the production process of plastic products, the raw materials are often transported and stored in the form of granules. During production, the plastic granules need to be processed. Since common plastic products usually adopt injection molding technology, the plastic granules need to be melted during injection molding. It takes a long time for the plastic granules to be converted from room temperature to a melted state in the injection molding machine. Therefore, the injection molding machine requires a longer heating channel, resulting in a larger injection molding machine and lower injection molding efficiency. Therefore, the raw materials need to be preheated before processing plastic tableware.

[0003] Common preheating devices usually place raw materials into a storage tank and heat the storage tank, and use a stirring rod to stir the plastic particles. However, relying solely on the stirring rod for stirring, the displacement of the plastic particles relative to each other is limited, and the temperature of the particles close to the side wall of the storage tank rises first, while the temperature of the plastic particles located in the center of the storage tank is still at a lower state, resulting in uneven heating of the preheated particles. At the same time, common preheating devices are unable to accurately and quantitatively discharge the plastic particles during discharge, which easily leads to material waste during the injection molding process.

[0004] Therefore, a feeding preheating mechanism for processing plastic tableware is proposed. Utility Model Content

[0005] The utility model provides a feeding preheating mechanism for processing plastic tableware, which solves the problem that common preheating devices in the prior art heat plastic particles unevenly, and achieves the purpose of quantitatively discharging heated plastic particles.

[0006] The utility model is realized by the following technical solutions: a feeding preheating mechanism for processing plastic tableware, comprising a storage tank, a top plate installed on the top of the storage tank, a stirring device for stirring provided inside the storage tank, a discharge device provided below the storage tank, a spiral heating tube installed on the outer surface of the storage tank, and the spiral heating tube connected to the output end of the external heating device;

[0007] The stirring device includes a rotating rod installed on the bottom surface of the top plate, the rotating rod is rotatably connected to the top plate, a first auger is fixed to the outer surface of the rotating rod, a connecting plate is fixed to the outer surface of the rotating rod, the other end of the connecting plate is rotatably connected to a driven rod, and a second auger is fixed to the outer surface of the driven rod.

[0008] The upper surface of the connecting plate is rotatably connected to a gear, and the driven rod passes through the connecting plate and is fixed to the gear. A gear ring is fixed to the inner wall of the storage tank, and the gear is meshed with the gear ring. The connecting plate can drive the gear to revolve. Since the gear is meshed with the gear ring, the gear rotates while revolving. The rotation of the gear drives the driven rod to rotate, and the rotation of the driven rod drives the second auger to rotate.

[0009] The discharging device includes an outer cylinder, the storage tank is connected to the outer cylinder, the outer surface of the outer cylinder is fixedly connected to a discharge pipe, the inner wall of the outer cylinder is rotatably connected to a rotating column, the outer surface of the rotating column is provided with a storage bin, the inner wall of the storage bin is slidably connected to a lifting plate, and the volume of the storage bin is changed by lifting and lowering the lifting plate.

[0010] A chamber is provided on the inner wall of the rotating column, an electric push rod is installed on the inner wall of the chamber, a movable disk is fixed on the output end of the electric push rod, a rotating plate is hinged on the side of the movable disk, an opening is provided on the bottom surface of the storage bin, the opening is connected to the chamber, and the other end of the rotating plate is hinged to the lifting plate.

[0011] Furthermore, a slider is fixed to the inner wall of the storage bin, and a slide groove is provided on the side of the lifting plate. The slider is slidably connected to the slide groove, and the lifting plate is maintained to be stably lifted and lowered through the sliding connection between the slider and the slide groove.

[0012] A transverse plate is fixed to the inner wall of the outer cylinder, an adjusting motor is installed on the side of the transverse plate, an output end of the adjusting motor is fixed to the rotating column, and the rotating column can be driven to rotate by the adjusting motor.

[0013] An outer sheath is fixed on the outer surface of the storage tank, a stirring motor is installed on the upper surface of the top plate, and an output end of the stirring motor is connected to the rotating rod.

[0014] The utility model provides a feeding preheating mechanism for processing plastic tableware, which has the following beneficial effects:

[0015] 1. The feeding preheating mechanism for processing plastic tableware can heat the side wall of the storage tank through the spiral heating tube. The rotation of the first auger causes the material at the bottom end of the center position of the storage tank to rise, and the rotation of the second auger causes the material near the side wall of the storage tank to fall, thereby uniformly mixing the material in the storage tank and allowing the material to contact the side wall of the storage tank to complete preheating, thereby solving the problem of uneven heating of plastic particles by the common preheating device in the prior art.

[0016] 2. The feeding preheating mechanism for processing plastic tableware can drive the movable plate to move through the electric push rod. The movement of the movable plate drives the rotating plate to rotate. The rotation of the rotating plate drives the lifting plate to move up and down. The volume of the storage bin is changed by the lifting and lowering of the lifting plate, thereby changing the volume of the material entering the storage bin at a single time. When the rotating column drives the storage bin containing the material to rotate to the discharge pipe, the material leaves through the discharge pipe to complete the quantitative discharge.
