Description

[Technical Field]

[0001] This invention relates to plastic recycling technology, and in particular to a recycling extrusion system for waste or damaged soft plastic materials such as plastic bags and films, which can effectively crush, compress and convert them into plastic granules for reuse. [Previous 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 the prior art, a twin-screw extruder is generally 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, the existing technology still needs improvement to enhance recycling efficiency and extrusion quality. [Summary of the Invention]

[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 granule raw materials through a special extrusion mechanism. It can adapt to plastic bags of different thicknesses, ensure the stability and efficiency of recycling extrusion, and has the advantages of energy saving and easy operation.

[0005] To achieve the above objective, the film recycling extrusion system of the present invention comprises:

[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: It consists of a main screw and an auxiliary wheel. When the plastic bag is fed into the feed port, the main screw rotates and drives the auxiliary wheel to rotate, which forcefully pulls the plastic bag into the main screw for extrusion.

[0008] 3. Auxiliary wheel and adjustment mechanism: The auxiliary wheel is installed on the auxiliary rocker arm. The rocker arm has a fulcrum in the center 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 adapt to different types of plastic materials.

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

[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, forming an effective extrusion action, which allows the plastic bag to pass smoothly through the extrusion system and be transformed into recyclable plastic granules.

[0012] The technical features of the present invention are as follows:

[0013] 1. Through the cooperation of 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, thereby 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 plastic pellets.

Implementation Method

[0016] The structure and operation of the film recycling extrusion system (100) of the present invention will be described in detail below with reference to the accompanying drawings. The present 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), etc. The structure and operation of each component are as follows:

[0017] Please refer to Figures 1 through 3;

[0018] 1. Feeding mechanism (10)

[0019] The feeding mechanism (10) is provided 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).

[0020] 2. Extrusion Mechanism (20)

[0021] 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.

[0022] 3. Auxiliary wheels and adjustment mechanism (30)

[0023] 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 provided 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) to ensure the stability and adaptability of the extrusion process.

[0024] 4. Drive mechanism (40)

[0025] 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).

[0026] 5. Discharge port (50)

[0027] 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.

[0028] Please refer to Figure 4. The operation process is as follows:

[0029] 1. The plastic bag (P) enters the extrusion mechanism (20) through the feed port (11).

[0030] 2. The main screw (21) rotates to the left, driving the plastic bag (P) into the extrusion zone, while the auxiliary wheel (31) rotates to the right, providing stable tension.

[0031] 3. Auxiliary wheel (31) Adjust the spacing according to the thickness of the plastic bag (P) to ensure moderate pressure and avoid jamming or excessive squeezing.

[0032] 4. After the plastic bag (P) is heated and melted, the plastic granules (G) are discharged through the discharge port (51) to complete the recycling process.

[0033] Technical Features and Advantages:

[0034] 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).

[0035] 2. Spring (34) adaptive adjustment mechanism, which can automatically adjust the pressure according to the thickness of the plastic bag (P) to improve adaptability.

[0036] 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).

[0037] 4. Low energy consumption, simple structure, and easy operation, suitable for various plastic film recycling production lines.

[0038] In summary, the film recycling extrusion system (100) of the present 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 converted into plastic granules (G), effectively improving recycling efficiency and product quality.
