[0033] The following uses specific embodiments to illustrate the present invention, but it is not a limitation to the invention.

[0034] Embodiment 1

[0035] As Figures 1-8 shown, in this embodiment, a plastic recycling equipment for woven bags is provided, including a cleaning tank 1, a conveyor belt 2, a crushing cylinder 3 and a discharge rack 5.

[0036] The inside of the cleaning tank 1 is provided with a cleaning chamber 6. A support body 7 is arranged in the middle of the cleaning chamber 6. A cover body 4 is arranged outside the support body 7 in the cleaning chamber 6. The support body 7 is arranged in the middle of the cleaning tank 1, so that the conveyor belt 2 and the crushing cylinder 3 can be installed in the middle position of the cleaning tank 1, so that the crushing cylinder 3, the conveyor belt 2 and the cleaning tank 1 are distributed in sequence from top to bottom. This installation method has significant advantages. On the one hand, it can effectively reduce the floor area and optimize the space layout of the equipment; on the other hand, it can shorten the moving and conveying distance of the materials, greatly improve the working efficiency, and make the operation of the entire plastic recycling equipment more efficient and convenient.

[0037] The conveyor belt 2 is installed above the support 7. The discharge end of the conveyor belt 2 extends to the cleaning chamber 6. It is installed above the support 7 and is driven by a power device such as a motor to operate. It transports the materials placed at the feeding end along a certain direction, and its discharge end extends to the cleaning chamber 6. The materials will enter the cleaning chamber 6 along the discharge end. It realizes the automatic transmission of materials, transports the materials that have undergone preliminary treatments such as crushing from one position to another position, facilitating subsequent cleaning, transfer and other operations, and improving the coherence and automation degree of the production process.

[0038] The crushing cylinder 3 is installed above the conveyor belt 2. There is a discharge port at the bottom of the crushing cylinder 3. The discharge port is arranged at the feeding end of the conveyor belt 2. The crushed materials fall from the discharge port to the feeding end of the conveyor belt 2. It crushes the larger plastic materials into smaller particles or fragments, facilitating subsequent cleaning and injection molding processing, increasing the contact area between the materials and the cleaning liquid, improving the cleaning effect, and also more meeting the requirements of the equipment for the material size.

[0039] One end of the discharge rack 5 extends into the interior of the cleaning tank 1, and the other end tilts upward. During the operation, the scraping strip on the discharge rack 5 contacts the materials in the cleaning liquid, scrapes up the materials from the cleaning liquid and conveys them upward along the discharge rack 5, and finally conveys them to the external storage device. It separates the cleaned materials from the cleaning liquid and outputs them to the storage device, completing the process of recycling and collecting the materials, ensuring that the cleaned materials can be stored orderly, facilitating subsequent further utilization;

[0040] Among them, the cleaning chamber 6 is an annular channel. The annular channel is arranged at the outer edge of the cleaning tank 1. This setting method can increase the flow distance of the cleaning liquid, thereby improving the cleaning efficiency. The cleaning liquid is injected into the interior of the cleaning chamber 6. There are multiple flow-pushing strips 9 moving along the annular channel at the bottom of the cleaning chamber 6. During the movement of the multiple flow-pushing strips 9, they drive the cleaning liquid to flow along the preset direction. There is a scraping strip on the discharge rack 5. The scraping strip can convey the materials inside the cleaning liquid to the storage device outside the recycling device. It uses the flowing cleaning liquid to clean plastics and other materials entering the cleaning chamber 6, removing surface dirt, impurities, etc., providing relatively clean raw materials for subsequent processing, and improving the quality of recycled plastics.

[0041] Embodiment 2

[0042] As Figures 1-8 shown, on the basis of Embodiment 1, this embodiment provides the structure of the cleaning chamber 6, which is specifically as follows:

[0043] The cleaning chamber 6 is composed of two parallel channels connecting two semi-circular channels. The semi-circular channels are arranged at both ends of the two parallel channels. The conveyor belt 2 extends to one of the semi-circular channels, and a circular channel is formed in the cleaning chamber 6. During the cleaning process, the cleaning liquid circulates in this circular channel. The conveyor belt 2 extends to one of the semi-circular channels. When the material is conveyed by the conveyor belt 2 to the position of the semi-circular channel, it enters the cleaning liquid for cleaning. Due to the circular arrangement of the channels, the cleaning liquid can continuously scour the material. On the one hand, the design of the circular channel increases the flow distance of the cleaning liquid, enabling the cleaning liquid to come into contact with the material more fully, thereby improving the cleaning efficiency. On the other hand, this specific circular structure facilitates the orderly movement of the material in the cleaning chamber 6, ensuring that each material can be cleaned evenly and effectively, providing cleaner raw materials for subsequent processing.

[0044] A connecting belt 8 is fitted and installed on the outer wall of the support body 7. A plurality of flow-pushing strips 9 are all installed on the connecting belt 8. When the motor inside the support body 7 for driving the second gear 11 to rotate works, the second gear 11 rotates to drive the inner teeth of the connecting belt 8 meshing with it, causing the connecting belt 8 to move circularly on the outer wall of the support body 7, and then driving the flow-pushing strips 9 installed on the connecting belt 8 to move together. During the movement of the flow-pushing strips 9, they will exert a force on the cleaning liquid at the bottom of the cleaning chamber 6, pushing the cleaning liquid to flow along the preset direction. By driving the cleaning liquid to flow through the flow-pushing strips 9, a directional circulating water flow can be formed for the cleaning liquid. This flowing cleaning liquid can better scour the surface of the material, removing dirt and impurities. Compared with the static cleaning liquid, the cleaning effect is greatly improved, and it also helps to maintain the uniform distribution of the cleaning liquid in the cleaning chamber 6, ensuring the consistent cleaning efficiency throughout the cleaning chamber 6.

[0045] An annular groove is provided inside the discharge rack 5. Driving strips are provided on both sides of the annular groove. Both ends of the scraping strip are respectively installed on the driving strips. When the driving mechanism for driving the discharge rack 5 to rotate on the discharge rack 5 works, the discharge rack 5 starts to rotate, and at the same time, the driving strips move along a specific track in the annular groove, driving the scraping strip to move. During the operation of the scraping strip, it comes into contact with the material in the cleaning liquid, scraping the material from the cleaning liquid and conveying it upward along the discharge rack 5.

[0046] Scraping claws are installed on the scraping strip and extend outward. When the scraping strip operates in the cleaning liquid, the scraping claws can penetrate into the material pile. Using their sharp ends and outward extension angles, they can more effectively grab the material. During the process of the scraping strip conveying the material upward along the discharge rack 5, the scraping claws can firmly hold the material to prevent it from falling.

[0047] One end of the discharge rack 5 that tilts upward is provided with an air outlet, and the air outlet direction of the air outlet faces the bottom. When the material is conveyed upward along the discharge rack 5 by the scraping strip to the position of the air outlet, the airflow blown out by the air outlet will blow the material. The airflow can blow off the cleaning liquid remaining on the surface of the material and some fine impurities. Through the air blown out by the air outlet, the cleaned material is preliminarily dried and the impurities are removed. Reducing the moisture and impurities on the surface of the material is beneficial to the subsequent storage and further processing of the material, improving the quality of the recycled plastic, and at the same time reducing the risk of the material deteriorating or sticking due to moisture during storage.

[0048] A driving mechanism for driving the discharge rack 5 to rotate is installed on the discharge rack 5. When the driving mechanism is started, it will output power to drive the discharge rack 5 to rotate around its installation axis. The rotation of the discharge rack 5 enables the scraping strip to perform a circular motion in the cleaning liquid, thereby continuously scraping the material from the cleaning liquid and conveying it upward.

[0049] A second gear 11 is rotatably installed inside the support body 7. Teeth are provided on the inner side of the connecting belt 8, and the second gear 11 is meshed and connected with the teeth. A motor for driving the second gear 11 to rotate is fixed inside the support body 7. When the motor inside the support body 7 for driving the second gear 11 to rotate is started, the motor drives the second gear 11 to rotate. The rotation of the second gear 11 drives the connecting belt 8 to move in a cycle on the outer wall of the support body 7 through the teeth, thereby driving the pushing strip 9 installed on the connecting belt 8 to move. This transmission method of meshing the second gear 11 with the teeth of the connecting belt 8 can accurately control the moving speed and direction of the pushing strip 9, thereby realizing the precise control of the flow speed and direction of the cleaning liquid.

[0050] Embodiment Three

[0051] Such as Figure 1 、 Figure 2 And Figure 4 As shown, on the basis of Embodiment One and Embodiment Two, this embodiment provides a way of shredding, which is specifically as follows:

[0052] The shredding cylinder 3 is a long strip cylinder. Two shredding rollers are rotatably installed inside the long strip cylinder. The length directions of the two shredding rollers are consistent with the length direction of the conveyor belt 2. The two shredding rollers are arranged above the conveyor belt 2. The material shredded by the shredding cylinder 3 can directly fall on the conveyor belt 2, and the length direction of the shredding cylinder 3 being consistent with the conveying direction of the conveyor belt 2 can extend the shredding channel. Compared with the traditional square shredding cylinder 3, the feeding area of the woven bag can be increased. The shredding cylinder 3 is a long strip cylinder, with two shredding rollers rotatably installed inside, and the length directions of the shredding rollers are consistent with the length direction of the conveyor belt 2.

[0053] When the motor drives one of the first gears 10 to rotate, since the two first gears 10 are meshed with each other, it will drive the other first gear 10 and the shredding roller connected coaxially therewith to rotate synchronously. Plastic materials such as woven bags are put into one end of the shredding cylinder 3, and under the action of the opposite rotation of the two shredding rollers, they are shredded into smaller particles or fragments, and then fall from the bottom discharge port of the shredding cylinder 3 to the feeding end of the conveyor belt 2. The design of the long strip cylinder and the consistent direction of the shredding roller and the conveyor belt 2 extend the shredding channel and increase the feeding area of materials such as woven bags, enabling more materials to enter the shredding cylinder 3 for shredding treatment simultaneously, and improving the shredding efficiency.

[0054] A driving housing 12 is fixed at the end of the shredding cylinder 3. Two mutually meshing first gears 10 are rotatably installed inside the driving housing 12. The two first gears 10 are respectively connected coaxially with the two shredding rollers. An electric motor for driving any one of the first gears 10 to rotate is fixed outside the driving housing 12. When the electric motor outside the driving housing 12 works, the output shaft of the electric motor drives the first gear 10 connected thereto to rotate. Since the two first gears 10 are meshed with each other, the other first gear 10 will rotate in the opposite direction accordingly, thereby driving the two shredding rollers to rotate in opposite directions.

[0055] Working principle:

[0056] When the plastic recycling equipment is in operation, first, plastic materials such as woven bags to be recycled are placed at the feeding end of the shredding cylinder 3. After being shredded in the shredding cylinder 3, the materials fall from the bottom discharge port to the feeding end of the conveyor belt 2. The conveyor belt 2 is driven by a power device such as an electric motor and transports the materials along a certain direction to the position where the cleaning chamber 6 is located. The materials enter the cleaning liquid in the cleaning chamber 6 along the discharge end of the conveyor belt 2. In the cleaning chamber 6, the push flow bar 9 moves driven by the connecting belt 8, pushing the cleaning liquid to circulate and flow, and flushing and cleaning the materials. The cleaned materials are scraped up by the scraping bar on the discharge rack 5 and are transported upward along the discharge rack 5 with the operation of the scraping bar and the assistance of the scraping claws. When the materials reach the air outlet position at the upwardly tilted end of the discharge rack 5, they are blown by the blown air flow to remove the residual cleaning liquid and fine impurities on the surface, and finally are transported to an external storage device, completing the entire process of plastic recycling.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate rather than limit the technical solutions of the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the present invention can still be modified or equivalently replaced. Any modification or partial replacement without departing from the spirit and scope of the present invention shall be covered by the scope of the claims of the present invention.
