Description

Technical Field

[0001] This utility model relates to the field of plastic product processing technology, and in particular to a device for recycling scrap materials from plastic bag production. Background Technology

[0002] Plastic bags, as a lightweight, durable, and inexpensive packaging material, are widely used in daily life, commercial distribution, and industrial production. They are typically made from thermoplastic resins such as polyethylene or polypropylene through processes like blown film forming, printing, and cutting. During plastic bag production, to meet size specifications, the film material needs to be cut or punched, inevitably generating a large amount of waste material. If this waste is not effectively recycled, it not only wastes raw materials but may also pollute the environment if disposed of in landfills or incinerated.

[0003] Currently, the industry commonly employs a combination of vacuum cleaners and shredding equipment for recycling scraps from plastic bag production. The vacuum cleaner uses negative pressure airflow to draw scraps from the production line into a dust collection device. After initial collection, the waste is transferred manually or mechanically to the shredding equipment, where it is processed into reusable plastic granules or sheets. This method achieves a certain degree of resource utilization of waste and reduces the risk of environmental pollution.

[0004] However, the transfer of materials between the vacuum cleaner and the crushing equipment relies on manual operation, which is not only labor-intensive and inefficient, but also prone to production line downtime due to operation delays. In addition, the phased operation mode makes it difficult to achieve continuous production, which restricts the improvement of overall processing efficiency. Utility Model Content

[0005] In order to overcome the shortcomings of discontinuous and inefficient processing, this utility model provides a continuous and efficient recycling device for scrap materials from plastic bag production.

The plastic bag processing equipment is used to produce plastic bags, and the crusher is used to crush the scraps generated from the plastic bags. A flow guide shroud is connected to the top of the crusher. One end of the recycling pipe is connected to the plastic bag processing equipment, and the blower is installed in the middle of the recycling pipe. The other end of the recycling pipe is connected to the flow guide shroud. A rotating shaft is rotatably connected inside the flow guide shroud, and a baffle is connected to the rotating shaft. The flow guide shroud has several exhaust ports, the diameter of which is smaller than that of the plastic bag scraps. A speed reduction assembly is provided on the side of the flow guide shroud to restrict the rotation of the rotating shaft.

[0007] As a further preferred embodiment, the deceleration assembly includes an adjusting screw, the flow guide is threadedly connected to the adjusting screw, the top of the adjusting screw is slidably connected to an operating rod, and the bottom of the adjusting screw is rotatably connected to a pressing plate, the pressing plate being pressed into the rotating shaft.

[0008] As a further preferred embodiment, a rubber pad is connected to the bottom surface of the extrusion plate, and the rubber pad is in contact with the rotating shaft.

[0009] As a further preferred embodiment, the air deflector is connected to a filter screen, which closes all the exhaust vents.

[0010] As a further preferred embodiment, an exhaust hood is connected to the front side of the air deflector, and the exhaust hood covers all the exhaust ports.

[0011] As a further preferred embodiment, the fairing is provided with a transparent observation window on its side.

[0012] Compared with the prior art, the present invention has the following advantages:

[0018] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0019] Example: A device for recycling scrap materials from plastic bag production, such as... Figures 1-3 As shown, the equipment includes a plastic bag processing device 1, a recycling pipe 2, a blower 3, a crusher 4, a flow guide 5, a rotating shaft 6, baffles 7, exhaust vents 8, and a speed reduction assembly. The plastic bag processing device 1 is used to produce plastic bags, and the crusher 4 is used to crush the scraps generated during the production process. The top of the crusher 4 is connected to the flow guide 5. One end of the recycling pipe 2 is connected to the plastic bag processing device 1, and the blower 3 is installed in the middle. The other end is connected to the flow guide 5. The connection between the recycling pipe 2 and the flow guide 5 is made of a soft sealing ring to prevent air leakage. The rotating shaft 6 is rotatably connected inside the flow guide 5. The middle of the rotating shaft 6 is connected to four baffles 7 that are arranged in a cross shape. The surface of the baffles 7 is covered with a low-friction coating to reduce adhesion to the scraps. Several exhaust vents 8 are opened on the side wall of the flow guide 5. The diameter of the exhaust vents 8 is smaller than that of the plastic bag scraps. A speed reduction assembly is installed on the side of the flow guide 5 to restrict the rotation of the rotating shaft 6.

[0020] like Figure 1 and Figure 3 As shown, the deceleration assembly includes an adjusting screw 9, a pressing plate 10, and an operating rod 11. The flow guide shroud 5 is threadedly connected to the adjusting screw 9. The surface of the adjusting screw 9 is plated with hard chrome to enhance wear resistance. The top of the adjusting screw 9 is slidably connected to the operating rod 11, and the bottom of the adjusting screw 9 is rotatably connected to the pressing plate 10. The pressing plate 10 is pressed and engaged with the rotating shaft 6. The bottom surface of the pressing plate 10 is provided with an arc-shaped contact surface to fit the rotating shaft 6.

[0021] like Figure 3 As shown, it also includes a rubber pad 12. The bottom surface of the extrusion plate 10 is connected to the rubber pad 12. The rubber pad 12 is in contact with the rotating shaft 6. The bottom surface of the rubber pad 12 is provided with cross-texture to increase the coefficient of friction with the rotating shaft 6.

[0022] like Figure 2 As shown, it also includes a filter screen 13. The air guide shroud 5 is connected to the filter screen 13. The filter screen 13 seals all the exhaust ports 8 to prevent waste from getting stuck in the exhaust ports 8, while ensuring smooth airflow.

[0023] like Figure 1 As shown, it also includes an exhaust hood 14. The exhaust hood 14 is connected to the front side of the guide hood 5, and the exhaust hood 14 covers all the exhaust ports 8.

[0024] like Figure 1 As shown, it also includes an observation window 15. The side of the flow guide 5 is provided with an observation window 15 made of transparent material, which makes it convenient for staff to clearly monitor the rotation speed of the internal baffle 7 and the status of waste materials.

[0025] Workers start the plastic bag processing equipment 1 to produce plastic bags. The waste material from cutting falls onto the equipment. Simultaneously, workers turn on the blower 3 and the crusher 4. The blower 3 directs the airflow within the recycling pipe 2, drawing in air at the end connected to the equipment. This airflow travels along the recycling pipe 2 into the flow guide shroud 5. The negative pressure created at the end of the recycling pipe 2 draws in the waste material from the plastic bag production process, which then follows the airflow along the recycling pipe 2 into the flow guide shroud 5. After entering the flow guide shroud 5, the airflow from the recycling pipe 2 comes into contact with the baffle 7, and the airflow... The impact of the baffle 7 causes it to rotate along with the shaft 6. Thus, the shaft 6 and the baffle 7 rotate counterclockwise inside the guide shroud 5. The continuously entering airflow is ejected from the exhaust port 8 of the guide shroud 5. The exhaust shroud 14 gathers all the airflow ejected from the exhaust port 8, enabling directional airflow and assisting in the cooling of other equipment. The scrap material that follows the airflow into the guide shroud 5 is separated by the baffle 7. When two adjacent baffles 7 are located at the top of the crusher 4, the scrap material falls into the crusher 4. The crusher 4 crushes the fallen scrap material. The crushed particles or debris are easy to process into raw materials, realizing the recycling of waste materials.

[0026] When there is little scrap material, the intake airflow is not restricted by the scrap material, and the stable airflow can maintain a sufficient speed in the recovery pipe 2. If the airflow velocity entering the guide hood 5 is too high, the operator can observe through the observation window 15 that the rotation speed of the baffle 7 is too high, causing the scrap material to stick to the baffle 7 and making it difficult to fall into the crusher 4 in time. At this time, the operator rotates the adjusting screw 9 by operating the lever 11. The adjusting screw 9 feeds downward along the thread of the guide hood 5, pushing the extrusion plate 10 close to the rotating shaft 6. Then the rubber pad 12 contacts the rotating shaft 6. The friction between the rubber pad 12 and the rotating shaft 6 restricts the rotation of the rotating shaft 6, thereby slowing down the baffle 7 and ensuring that the scrap material can fall down in time for crushing. After the plastic bag production stops, the blower 3 and the crusher 4 are turned off. The filter screen 13 can not only prevent the scrap material from clogging the exhaust port 8 and retain the normal flow of gas, but also prevent external foreign objects from entering the interior of the guide hood 5.

[0027] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of the present invention and should not be construed as limiting the scope of protection of the present invention in any way. Based on this explanation, those skilled in the art can conceive of other specific embodiments of the present invention without creative effort, and these embodiments will all fall within the scope of protection of the present invention.
