Description

Technical Field

[0001] The utility model relates to a continuous automatic blanking device, in particular to a continuous automatic blanking device for plastic molding processing, belonging to the technical field of plastic molding processing. Background Art

[0002] Plastic molding is the process of plastic processing and molding, including injection molding, extrusion molding, compression molding, blow molding, etc. Injection molding requires the use of an injection molding machine, which is the main molding equipment for thermoplastic plastics or thermosetting plastics using plastic molding molds to make plastic products of various shapes. The injection molding machine needs to add plastic particles into the injection molding device during injection molding, and this process requires a blanking device.

[0003] Common injection molding devices use a direct unloading method when unloading materials. The injection molding device is screw-type. When an injection molding is in the blow molding state, the screw does not rotate and the plastic particles are not consumed. The plastic particles in the unloading device will accumulate at the discharge port waiting to enter the injection molding device. A large amount of accumulation may cause blockage or unsmooth unloading, thereby affecting the speed of plastic molding processing. At the same time, during the injection molding process, the plastic particles will not be heated and melted until they enter the injection molding device. It takes a long time to heat the plastic particles from room temperature to the melted state. In order to ensure that it does not affect the continuity of the plastic finished product, the heating component of the injection molding device needs to be set to a longer length, which results in more space required in the horizontal direction and an increase in floor space.

[0004] Therefore, a continuous automatic unloading device for plastic molding processing is proposed. Utility Model Content

[0005] The utility model proposes a continuous automatic unloading device for plastic molding processing, so as to solve the problem that the common continuous automatic unloading device in the prior art is prone to blockage when the injection molding device is in the blow molding state. At the same time, preheating is completed during the unloading process, which shortens the time required for the injection molding device to heat and melt plastic particles and reduces the overall floor space.

[0006] The utility model is realized by the following technical solutions: a continuous automatic unloading device for plastic molding processing, comprising a bottom plate, an upper surface of which is provided with a unloading assembly for unloading materials, the unloading assembly comprising a tank body, an injection molding machine body for injection molding is provided above the bottom plate, and an output end of the tank body is connected to the injection molding machine body;

[0007] A top plate is fixed to the top of the tank body, the bottom surface of the top plate is rotatably connected to a rotating rod, the bottom end of the rotating rod is fixed to a first auger, the outer surface of the rotating rod is fixed to a rotating plate, the bottom surface of the rotating plate is rotatably connected to two driven rods, and the outer surfaces of the driven rods are each fixed with a second auger.

[0008] The blanking assembly also includes a gear ring fixed to the bottom surface of the top plate, the top end of the driven rod passes through the rotating plate, and the top end of the driven rod is fixed with a driven gear, which is engaged with the gear ring. The rotation of the rotating plate drives the driven rod to rotate around the rotating rod. At the same time, through the engagement of the driven gear and the gear ring, the driven gear rotates under the drive of the rotating plate, and the rotation of the driven gear drives the driven rod to rotate, and the rotation of the driven rod drives the second auger to rotate.

[0009] A motor is installed on the upper surface of the top plate, and the output end of the motor is fixed to the rotating rod. The rotating rod can be driven to rotate by the motor.

[0010] A spiral heating tube is installed on the outer surface of the tank body, and the spiral heating tube is connected to the output end of an external heating device. The spiral heating tube is heated by the external heating device to complete the heating of the tank body.

[0011] An outer sheath is fixed to the outer surface of the tank body. The size of the outer sheath is larger than the outer diameter of the spiral heating tube. A fixing rod is fixed between the outer sheath and the tank body. The outer sheath can protect the spiral heating tube to prevent the operator from accidentally touching the spiral heating tube and causing injury. At the same time, the outer sheath can also reduce the loss of heat from the spiral heating tube.

[0012] A feeding pipe is provided on the outside of the tank body. The feeding pipe passes through the outer sheath, and the other end of the feeding pipe is communicated with the tank body.

[0013] An auxiliary ring is fixed on the inner wall of the tank body. The auxiliary ring is located below the driven gear. The driven gear is slidably connected to the auxiliary ring. The auxiliary ring supports the driven gear and maintains the stability of the auxiliary gear.

[0014] The utility model provides a continuous automatic unloading device for plastic molding processing, which has the following beneficial effects:

[0015] 1. The continuous automatic unloading device for plastic molding processing drives the first auger to rotate by rotating the rotating rod. After the injection molding device completes the blow molding operation, the rotation of the first auger pushes the plastic particles to move. The moving plastic particles will flush out the plastic particles accumulated at the discharge port, avoiding the blockage of the discharge port, and solving the problem of easy blockage of the continuous automatic unloading device commonly seen in the prior art.

[0016] 2. The continuous automatic unloading device for plastic molding processing heats the tank body through a spiral heating tube. The rotation of the rotating rod drives the driven rod to rotate and then drives the second auger to rotate. The rotation of the second auger drives the material inside the tank body to move up and down, so that the heat of the tank body can be evenly transferred to the plastic particles inside the tank body, heating the plastic particles, realizing preheating during the unloading process, shortening the time required for the injection molding device to heat and melt the plastic particles, and reducing the overall floor space.

At the same time, through the engagement of the driven gear 209 with the gear ring 208, the driven gear 209 rotates under the drive of the rotating plate 205. The rotation of the driven gear 209 drives the driven rod 206 to rotate. The rotation of the driven gear 206 drives the second auger 207 to rotate.
