Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of mixing machine, especially to a plastic particle mixing machine for granulation. BACKGROUND

[0002] As a key equipment in modern industrial production, the development of mixing machine is closely related to the demand of industrial production. In the early stage, the mixing of materials relied on manual or simple machinery, which was low in efficiency and limited in mixing uniformity. With the promotion of industrial scale production, higher requirements were put forward for the efficiency, precision and automation of material mixing, which promoted the continuous iteration of mixing machine technology.

[0003] The existing plastic particle mixing machine directly pours raw materials into the mixing barrel for stirring without pretreatment, which makes the damp and clumped raw materials unable to be dispersed by the stirring rod in the barrel, affecting the stirring efficiency and quality and causing adverse effects on subsequent processing work. UTILITY MODEL CONTENTS

[0004] The utility model discloses a plastic particle mixing machine for granulation, which solves the problem of the existing plastic particle mixing machine, which directly pours raw materials into the mixing barrel for stirring without pretreatment, making the damp and clumped raw materials unable to be dispersed by the stirring rod in the barrel, affecting the stirring efficiency and quality and causing adverse effects on subsequent processing work.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A plastic particle mixing machine for granulation, comprising a mixing barrel and a rotating shaft, wherein the rotating shaft is rotatably connected in the mixing barrel, and two extrusion rods are fixedly connected to the outer surface of the rotating shaft.

[0007] A dispersing part is arranged in the mixing barrel, which comprises a screen, a cylinder, a return spring, a round rod, a ball and a dispersing rod. The screen is slidably connected to the inner wall of the mixing barrel, and two cylinders are fixedly connected to the inner wall of the mixing barrel. Two fixed rods are fixedly connected to the outer surface of the screen and slidably connected to the cylinder. The return spring is fixedly connected between the fixed rod and the inner wall of the cylinder. The round rod is fixedly connected to the fixed rod and slidably connected to the cylinder. The ball is fixedly connected to the end of the round rod away from the fixed rod. A plurality of dispersing rods are fixedly connected to the outer surface of the rotating shaft.

[0008] Preferably, the mixing barrel is fixedly connected with a feeding hopper.

[0009] Preferably, the outer surface of the mixing barrel is fixedly connected with a drying box, and the mixing barrel is fixedly connected with a placing box.

[0010] Preferably, an airbag is fixedly connected inside the placement box, and multiple push plates are slidably connected inside the placement box, with the push plates fixedly connected to the airbag.

[0011] Preferably, the airbag is fixedly connected to a nozzle, and a retaining ring is fixedly connected to the outer surface of the rotating shaft.

[0012] Preferably, a plurality of arc-shaped blocks are fixedly connected to the outer surface of the fixing ring, and the arc-shaped blocks are slidably connected to the push plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The screen moves up and down through the coordinated action of the return spring, fixing rod, ball, and other parts. The clumps of plastic particles on the screen bounce up and down, and the dispersing rod breaks up the bouncing plastic particles. At the same time, the clumps of plastic particles fall onto the screen, generating an impact force, which further disperses the clumps of plastic particles, preventing them from affecting subsequent processing and improving mixing efficiency and quality.

[0015] 2. Through the combined action of parts such as the arc-shaped block, push plate, and drying chamber, the gas in the airbag is applied to the screen through the nozzle. The drying gas can absorb the moisture in the clumped plastic granules, preventing the accumulation of moisture in the mixing tank, which would affect subsequent mixing work. This ensures that the mixing tank is in a relatively dry environment, guarantees the mixing quality of the plastic granules, and prevents clumping in subsequent processing.
