A plastic extruder with adjustable extrusion barrel temperature

Abstract

The invention discloses a plastic extruder with adjustable extruding barrel temperature. An outer protective cover is fixed on the surface of the frame, and the extruding barrel is horizontally erected inside the outer protective cover. Several cast aluminum heating sleeves are fixedly arranged on the arc side of the outer protective cover, and a feeding chamber is fixedly arranged at one end of the outer protective cover, and the discharge port of the feeding chamber passes through the outer protective cover and is arranged on the extruding cylinder. On the feeding port, a cooling pipe is fixed inside the cavity of the rotating shaft inside the extrusion barrel, and a temperature control box is installed on one side of the frame. By setting a stirring mechanism in the feeding chamber, the The plastic is stirred by the stirring mechanism in the feeding chamber, so that the mixing of the plastic raw materials is more uniform, and the extrusion quality of the extrusion barrel is improved. The adjustment of the temperature of the plastic raw material in the barrel makes the heating and cooling effects of the barrel more prominent.

Description

Technical field [0001] The present invention belongs to the field of plastic processing, and is specifically an extruder temperature adjustable plastic extruder. Background technique [0002] The plastic manufacturing process is an additive of various formulations in various plastics. After heating and pressurized, the performance of plastic is improved, enhance the toughness, intensity, fire resistance of plastic particles. [0003] Plastic extruder is an important production equipment that can be produced in plastics. Existing plastic extruders, with single screws, twin screws, multi-screws and non-screws in the form, respectively. [0004] Plastic extruders are used to complete plasticization and molding of plastics. The extruder heats the raw material to turn the solid feedstock into a uniform viscous fluid, and under the action of the extruder, the molten material is continuously extruded from the head of the head, becomes required. Plastic parts. The extruder extruded mecha...

AI Technical Summary

Problems solved by technology

[0006] 1. During the extrusion process of the single-screw plastic extruder, the plastic raw material drives the auger to convey and stir horizontally through the rotating shaft in the extrusion barrel, so that the plastic raw material is not evenly stirred, which affects the extrusion quality of the plastic raw material;

[0007] 2. The extrusion barrel of the single-screw plastic extruder is heated externally, so that the plastic solid material in the extrusion barrel becomes a uniform viscous fluid raw material. Since the outer wall of the extrusion barrel is heated, it is easy to cause the inside of the extrusion barrel to The plastic raw material in the middle position is heated unevenly during the heating process

[0008] 3. Existing plastic extruders usually use a single cooling fan to cool the extrusion barrel, resulting in long cooling time and low efficiency for the extrusion barrel
