Description

Technical Field

[0001] This utility model belongs to the field of plastic recycling technology, specifically relating to a plastic recycling device for the production of plastic products. Background Technology

[0002] In the plastics manufacturing industry, plastic recycling is of great significance for reducing production costs, minimizing environmental pollution, and improving resource utilization. Long strips of plastic, as a common form of plastic waste, have always faced numerous challenges in recycling. Traditional plastic recycling equipment often fails to achieve uniform feeding, chopping, and crushing of long strips of plastic. This results in uneven plastic feeding during the chopping process, leading to inconsistent sizes and quality of the shredded plastic. Furthermore, the unstable feeding of the shredded plastic in the subsequent crushing stage easily causes jamming and blockages, making it difficult to guarantee crushing efficiency. These problems not only affect the quality and efficiency of plastic recycling but also increase equipment maintenance costs, limiting the further development of the plastic recycling industry. Therefore, developing a device capable of sequentially and uniformly chopping and crushing long strips of plastic during recycling is urgently needed. Utility Model Content

[0003] The purpose of this invention is to provide a plastic recycling device for the production of plastic products, which can sequentially and uniformly shred and crush long strips of plastic during recycling, thereby improving the processing efficiency.

[0004] The specific technical solution adopted by this utility model is as follows:

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0024] like Figures 1-4 As shown, a plastic recycling device for plastic product manufacturing includes a housing 1, and the interior of the housing 1 is arranged in a plastic shredding zone, a plastic crushing zone and a plastic collection zone in a top-to-bottom order.

[0025] A feed pipe 2 is fixedly connected to the housing 1. The feed pipe 2 can be fixedly connected to the top of the housing 1 in a vertical position, or it can be fixedly connected to the top of the front end of the housing 1 in a horizontal position. In this technical solution, it is preferred that the feed pipe 2 is fixedly connected to the top of the front end of the housing 1.

[0026] The feed pipe 2 is equipped with a constant speed conveyor assembly, which is used to uniformly convey long strips of plastic to the plastic shredding area for shredding.

[0027] The aforementioned long strip of plastic can be a plastic tube or a plastic sheet.

[0028] Specifically, the constant-speed conveying group can be a rotating wheel or a conveyor belt. In this technical solution, a conveyor belt is preferred. Specifically, the constant-speed conveying group includes a conveyor belt, which includes a support plate 4 installed inside the feed pipe 2. Two circular wheels 5 are rotatably connected to the support plate 4. A transmission belt body 6 is driven to the outer side of the two circular wheels 5. A first motor 7, which is driven to the circular wheels 5, is also fixedly connected to the support plate 4. By starting the first motor 7, the circular wheels 5 are driven to rotate, which in turn drives the transmission belt body 6 to move. When the transmission belt body 6 moves, it will drive the long strip of plastic in contact with the transmission belt body 6 to move, thereby achieving the purpose of uniform speed feeding.

[0029] Among them, such as Figures 1-3 As shown, the number of conveyor belts is at least one;

[0030] When there is only one conveyor belt, the conveyor belt is fixedly connected to the lower side inside the feed pipe 2, so that the long strip of plastic comes into contact with the conveyor belt under the action of gravity.

[0031] When there are two conveyor belts, the conveyor belts are also fixedly connected to the lower side inside the feed pipe 2, so that the long strip of plastic comes into contact with the conveyor belt under the action of gravity.

[0032] When there are three conveyor belts, the three conveyor belts are arranged in a ring array inside the feed pipe 2. At this time, three electric push rods 3 are fixedly connected to the periphery of the feed pipe 2. The piston rods of the three electric push rods 3 are fixedly connected to the support plates 4 of the three conveyor belts respectively. At this time, the position of the conveyor belts can be adjusted by the electric push rods 3, so that the conveyor belts can contact tubular plastics of different sizes, and the three conveyor belts can stably guide the long strip plastics.

[0033] Among them, such as Figure 2 As shown, a material shredding mechanism for shredding plastic inside the plastic shredding zone is fixedly connected to the housing 1. The material shredding mechanism includes a second motor 8 fixedly connected to the outside of the feed pipe 2. The output end of the second motor 8 is fixedly connected to a crushing blade 9 located inside the plastic shredding zone. By starting the second motor 8, the crushing blade 9 is driven to rotate, which can shred the plastic inside the plastic shredding zone, cutting long strips of plastic into short strips of plastic. Since the feeding speed is relatively uniform, the shredded short strips of plastic are roughly the same size, which greatly facilitates the subsequent crushing process.

[0034] like Figure 2 and Figure 4 As shown, a plastic crushing mechanism for crushing plastic inside the plastic crushing zone is fixedly connected to the housing 1. The plastic crushing mechanism includes two crushing shafts 11 rotatably connected inside the plastic crushing zone. The ends of the two crushing shafts 11 are fixedly connected to gears 13 located outside the housing 1. The two gears 13 mesh with each other. A third motor 12 is fixedly connected to the outside of the housing 1 and is driven by the crushing shafts 11. At this time, by starting the third motor 12, the two crushing shafts 11 can be driven to rotate in opposite directions, so that the two crushing shafts 11 crush the short strip plastic. After the short strip plastic is crushed into block plastic, it falls into the plastic collection area. Since the feeding speed of the plastic crushing mechanism is relatively uniform, it is not easy to jam or block. The feeding process is relatively stable and can better ensure the crushing effect.

[0035] Guide sloping plates 10 are fixedly connected to the inner walls on both sides of the housing 1, located on the upper side of the crushing shaft 11. A discharge port is formed between the two crushing shafts 11. The side of the crushing shaft 11 near the discharge port is inclined downward, so that the falling short strips of plastic can be concentrated between the two crushing shafts 11 and be crushed by the crushing shafts 11.

[0036] Meanwhile, an opening opposite to the plastic collection area is provided at the lower end of the outer side of the casing 1. A storage box 14 is slidably connected inside the plastic collection area. The storage box 14 can enter and exit through the opening. When the block plastic falls, it will fall into the storage box 14. After collection, the storage box 14 can be pulled out to discharge the material.

[0037] In summary, this technical solution uses a constant-speed conveyor to uniformly transport long strips of plastic to the plastic shredding area for shredding. Because the shredding mechanism shreds the long strips of plastic at a relatively uniform speed, the shredded plastic can be fed uniformly to the plastic crushing mechanism for further crushing. Thus, when recycling long strips of plastic, they can be shredded and crushed sequentially and uniformly, improving the processing efficiency.

[0038] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
