Description

Technical Field

[0001] This invention relates to plastic recycling technology, specifically a recycling extrusion system for soft plastic materials such as discarded or damaged plastic bags and films, which can effectively crush, compress, and convert them into plastic pellets for reuse. Background Technology

[0002] Currently, the recycling of waste plastic bags mainly relies on crushing, washing, drying, and melt extrusion. However, because plastic bags and film materials are relatively soft and easily entangled, they are difficult to directly compress during the recycling process and need to be crushed and conveyed into the extruder through mechanical pulling or other methods.

[0003] In conventional technology, twin-screw extruders are typically used to process waste plastic bags, melting them and extruding them into granules. However, due to the ductility and strength of plastic bags, they are prone to jamming or tangling with the screw during the feeding stage, affecting processing efficiency. Therefore, existing technologies still need improvement to enhance recycling efficiency and extrusion quality. Utility Model Content

[0004] The purpose of this invention is to provide an improved film recycling extrusion system. This system effectively pulls waste or damaged plastic bags into the screw and converts them into plastic granules through a special extrusion mechanism. It can adapt to plastic bags of different thicknesses, ensuring the stability and efficiency of recycling extrusion, and has the advantages of energy saving and easy operation.

[0005] To achieve the above objectives, the film recycling extrusion system of this invention includes:

[0006] 1. Feeding mechanism: It is equipped with a feeding port, which is designed to be wider at the top and narrower at the bottom, for feeding waste plastic bags or film materials.

[0007] 2. Extrusion Mechanism: Composed of a main screw and an auxiliary wheel. When the plastic bag is fed into the feed port, the main screw rotates, driving the auxiliary wheel to rotate and forcefully pulling the plastic bag into the main screw for extrusion.

[0008] 3. Auxiliary wheel and adjustment mechanism: The auxiliary wheel is mounted on the auxiliary rocker arm, with a fulcrum in the center of the rocker arm and a spring on the other side of the auxiliary wheel. The distance between the main screw and the auxiliary wheel can be automatically adjusted according to the thickness of the plastic bag to accommodate different types of plastic materials.

[0009] 4. Drive mechanism: The main screw is driven by a motor to rotate continuously, which drives the plastic bag and squeezes it, ensuring that the plastic bag can be melted and extruded into granules.

[0010] 5. Discharge port: After the recycled plastic bags are squeezed and melted, the plastic granules are discharged from here.

[0011] During operation, the main screw rotates to the left and the auxiliary wheel rotates to the right, creating an effective squeezing action that allows the plastic bag to pass smoothly through the extrusion system and be transformed into recyclable plastic pellets.

[0012] The technical features of this work are as follows:

[0013] 1. By working together with the auxiliary wheel and the main screw, the problems of plastic bag entanglement and uneven feeding are effectively solved.

[0014] 2. The adaptive adjustment mechanism of the auxiliary wheel can automatically adjust the clamping distance according to the thickness of the plastic bag, improving adaptability.

[0015] 3. The main screw and the auxiliary wheel rotate relative to each other, providing a stable pulling force to ensure that the plastic bag enters the extrusion zone smoothly and is extruded into granules. Attached Figure Description

[0037] The structure and operation of the film recycling extrusion system (100) of this invention will be described in detail below with reference to the accompanying drawings. This invention mainly consists of a feeding mechanism (10), an extrusion mechanism (20), an auxiliary wheel and adjustment mechanism (30), a drive mechanism (40), and a discharge port (50). The structure and operation of each component are as follows:

[0038] Please refer to Figures 1 through 3;

[0039] 1. Feeding mechanism (10)

[0040] The feeding mechanism (10) is equipped with a feeding port (11), which is a funnel-shaped design that is wider at the top and narrower at the bottom, to ensure that the plastic bag (P) can slide smoothly into the extrusion mechanism (20).

[0041] 2. Extrusion mechanism (20)

[0042] The extrusion mechanism (20) mainly consists of a main screw (21) and an auxiliary wheel (31), as shown in Figure 2. When the plastic bag (P) is fed into the feed port (11), the main screw (21) rotates, and through the pushing action of the screw thread, it drives the plastic bag (P) into the extrusion zone. At the same time, the main screw (21) also drives the auxiliary wheel (31) to rotate, forming an effective clamping and pulling action, so that the plastic bag (P) is stably fed and extruded smoothly.

[0043] 3. Auxiliary wheels and adjustment mechanism (30)

[0044] The auxiliary wheel (31) is mounted on the auxiliary rocker arm (32) and connected to the machine base (M) through the fulcrum (33). One end of the auxiliary rocker arm (32) is equipped with a spring (34). When plastic bags (P) of different thicknesses pass through the extrusion mechanism (20), the spring (34) can automatically adjust the distance between the main screw (21) and the auxiliary wheel (31) according to the thickness of the plastic bag (P), so as to ensure the stability and adaptability of the extrusion process.

[0045] 4. Drive mechanism (40)

[0046] The drive mechanism (40) mainly consists of a motor (41) and a transmission shaft (42), which is responsible for providing power to the main screw (21). The motor (41) rotates clockwise (to the left), driving the main screw (21) to rotate, and further driving the auxiliary wheel (31) to rotate counterclockwise (to the right), forming a stable pulling and squeezing mechanism to ensure that the plastic bag (P) can be smoothly conveyed to the discharge port (50).

[0047] 5. Discharge port (50)

[0048] After the plastic bag (P) is heated and melted in the extrusion mechanism (20), it is finally extruded into plastic granules (G) through the discharge port (51) to complete the recycling and reuse.

[0049] The operation process is as follows:

[0050] 1. A plastic bag (P) enters the extrusion mechanism (20) through the feed port (11).

[0051] 2. The main screw (21) rotates counterclockwise, driving the plastic bag (P) into the extrusion zone, while the auxiliary wheel (31) rotates clockwise to provide stable tension.

[0052] 3. Auxiliary wheels (31) Adjust the spacing according to the thickness of the plastic bag (P) to ensure moderate pressure and avoid jamming or excessive squeezing.

[0053] 4. After the plastic bag (P) is heated and melted, plastic particles (G) are discharged through the discharge port (51), completing the recycling process.

[0054] Technical features and advantages:

[0055] 1. The cooperation between the auxiliary wheel (31) and the main screw (21) effectively solves the problems of uneven feeding and tangling of plastic bags (P).

[0056] 2. Spring (34) adaptive adjustment mechanism, which can automatically adjust the pressure according to the thickness of the plastic bag (P) to improve adaptability.

[0057] 3. The main screw (21) and the auxiliary wheel (31) rotate relative to each other, providing a stable pulling force to ensure that the plastic bag (P) can be smoothly extruded into plastic granules (G).

[0058] 4. Low energy consumption, simple structure, and easy operation, suitable for various plastic film recycling production lines.

[0059] In summary, the film recycling extrusion system (100) of this invention provides an efficient and stable method for recycling plastic bags. Through the combination of the feeding mechanism (10), the extrusion mechanism (20), the auxiliary wheel and adjustment mechanism (30), the drive mechanism (40) and the discharge port (50), it ensures that the plastic bag (P) will not get stuck during the extrusion process and can adapt to materials of different thicknesses, and finally be transformed into plastic granules (G), effectively improving recycling efficiency and product quality.
