Description

[Technical field]

[0001] The utility model relates to the technical field of plastic product molding, in particular to a stirring device for plastic processing. [Background technology]

[0002] The basic process of plastic product processing is to melt plastic particles and then extrude them into shape. Existing plastic products usually require the use of multiple different plastic particles at the same time due to different requirements for properties such as color, density and corrosiveness. Before hot melting the mixed plastic particles, they need to be stirred. The uniformity of stirring will directly determine the quality of the finished product.

[0003] The existing plastic stirring device generally drives the stirring shaft inside the stirring tank to rotate by a motor, and stirs the stirring tank by the stirring blades on the stirring shaft. For example, patent application number: 202221889178.2 discloses a PVC plastic material cooling mixer, and the stirring device includes a top cover, which is installed on the top surface of the stirring barrel, and the top surface of the top cover is vertically provided with a stirring motor, and the bottom surface of the top cover is vertically provided with a stirring shaft. The stirring motor drives the stirring shaft to rotate, and the stirring shaft is provided with stirring blades on the outer sleeve, and the stirring blades are located inside the stirring barrel. When the stirring motor is started, the stirring motor drives the stirring shaft to rotate, and the stirring shaft drives the stirring blades to rotate, so as to better stir the materials inside the stirring barrel. However, this type of stirring of the materials in the stirring barrel by the stirring blades cannot achieve the mixing of the bottom materials with the top materials, and the materials at the inner wall position of the stirring tank cannot be mixed with the materials in the middle position of the stirring tank, resulting in low stirring efficiency, and it takes a long time to achieve full stirring of the materials.

[0004] The utility model is proposed in view of the deficiencies in the prior art. [Utility Model Content]

[0005] The purpose of the utility model is to overcome the disadvantages of the prior art and provide a stirring device for plastic processing.

[0006] The utility model can be realized by the following technical solutions:

[0007] The utility model discloses a stirring device for plastic processing, comprising a stirring tank fixed on a frame, a feeding port being arranged on the stirring tank, a discharging pipe being fixed on the bottom of the stirring tank, and a turntable being arranged on the stirring tank. The turntable is driven to rotate by a rotary motor, a plurality of lifting devices are fixed on the turntable, the lifting devices comprise a lifting pipe fixed obliquely below the turntable, a lifting motor is fixed on the turntable, the output end of the lifting motor is fixed to a lifting shaft in the lifting pipe, and a spiral blade is fixed on the lifting shaft. The material to be mixed is discharged into the mixing tank through the feed inlet, and the lifting shaft is driven to rotate by the lifting motor. The spiral blade rotates with the lifting shaft, and the spiral blade and the lifting pipe form a spiral lifting device. The material below the lifting pipe passes through the lifting pipe and reaches the top of the lifting pipe, so that the material below is mixed with the material above. The lifting pipe is tilted and fixed under the turntable, and the turntable is driven to rotate by the rotating motor. The lifting pipe rotates with the turntable, and the mixing tank is stirred through the lifting pipe to achieve stirring of the material in the mixing tank. The lifting pipe rotates with the turntable, and the lifting pipe absorbs the material at the inner wall of the mixing tank and discharges it through the lifting pipe, so that the material at the inner wall of the mixing tank is mixed with the material in the middle of the mixing tank, so that the materials can be fully mixed, and the mixing speed is fast.

[0008] Preferably, a circular rack is fixed on the turntable, and a gear is fixed on the output end of the rotating motor, and the gear is meshed with the circular rack.

[0009] Preferably, the bottom of the spiral blade is below the riser.

[0010] Preferably, a stirring motor is also fixed on the frame, an output end of the stirring motor is fixed to a stirring shaft in the stirring tank, and a stirring blade is also fixed on the stirring shaft.

[0011] Compared with the existing technology, the utility model has the following advantages:

[0012] The spiral blades and the lifting pipe form a spiral lifting device. The material below the lifting pipe passes through the lifting pipe and reaches above the lifting pipe, so that the material below is mixed with the material above. The lifting pipe is tilted and fixed below the turntable. The turntable is driven to rotate by a rotating motor. The lifting pipe rotates with the turntable. The mixing tank is stirred through the lifting pipe to achieve stirring of the material in the mixing tank. The lifting pipe rotates with the turntable.
