AI Technical Summary
Plastic granules tend to stick together and accumulate in the feeding device, resulting in uneven mixing, which affects the consistency of the finished product coloring, and some granules may remain and affect the next coloring.
The threaded groove of the adjusting rod drives the arc-moving frame to move, adjusting the gap between the discharge arc and the inclined plate, controlling the input flow rate of different plastic granules, and accumulating them in sections in the hopper. The inclined plate guides the granules as they fall, achieving uniform mixing.
This solution resolves the issue of color variations in finished products caused by uneven mixing of plastic granules, reduces granule residue, and ensures the accuracy and consistency of subsequent color adjustments.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic processing technology, and specifically discloses a plastic extruder. Background Technology
[0002] Plastics processing, also known as plastic molding, is a general term for various processes that transform synthetic resins or plastics into plastic products. It is a major production sector within the plastics industry. Plastics processing generally includes plastic batching, molding, machining, joining, finishing, and assembly. The latter four processes are carried out after the plastic has been molded into finished or semi-finished products, and are also known as secondary plastic processing.
[0003] Plastic extruders are common plastic processing equipment. During plastic processing, three primary color plastic granules need to be fed in to match the color of the finished product. However, due to the characteristics of plastic granules, they are prone to sticking and accumulating on the inner wall of the feeding device. Over time, this will affect the color matching of the next finished product. Since the amount of three primary color plastic granules fed in is not necessarily equal, if they are fed into the device at the same time, a small amount of plastic granules may be consumed first, which will affect the color matching of the subsequent plastic finished product. Therefore, a plastic extruder is needed to solve this problem. Utility Model Content
[0004] This utility model proposes a plastic extruder that uses the threaded groove of the adjusting rod to drive the arc shifting frame to move outward, thereby causing the arc shifting frame to pull the feeding arc to move, creating a gap between the feeding arc and the inclined plate that is connected to the feeding pipe.

[0026] As a technical optimization of this utility model, the feeding pipe 6 is a circular pipe, and three arc-shaped grooves are equidistantly provided on the upper surface of the feeding pipe 6. A feeding arc 7 is slidably connected to the inner surface of the arc-shaped grooves. Three circular grooves of equal diameter are equidistantly provided on the outer circumference of the feeding pipe 6, and an adjusting rod 9 is rotatably connected to the inner surface of the circular grooves.

[0029] In this embodiment: the discharge arc 7 is used to prevent the particles in the hopper 12 from sliding into the feeding pipe 6 by contacting the outer arc surface of the inclined panel 15, and to adjust the number of plastic particles falling according to the moving distance of the discharge arc 7.
[0030] As a technical optimization of this utility model, the arc-moving frame 8 is a square plate. The outer surface of the arc-moving frame 8 is provided with a circular groove, and the inner wall of the circular groove is provided with a threaded groove. The upper and lower outer surfaces of the arc-moving frame 8 are provided with rectangular plates, and the outer surface of the upper rectangular plate is fixedly connected with a feeding arc 7.

Then, according to the specific quantity and proportion of plastic particles, the auxiliary rotating frame 11 is rotated, which drives the adjusting rod 9 to rotate. This causes the threaded groove of the adjusting rod 9 to move the arc shifting frame 8 to the outside of the device, thereby causing the arc shifting frame 8 to pull the discharge arc 7 to move. This creates a gap between the discharge arc 7 and the inclined plate 15 that is connected to the feeding pipe 6, allowing plastic particles from different sections to enter the feeding pipe 6 at different speeds. After entering the heating pipe 3, the plastic particles are heated and melted, then drawn and crushed by the feeding rod 5, and finally extruded from the discharge port 1 through the filter plate 2.
