Description

Technical Field

[0001] This utility model relates to the field of resource recycling technology, and in particular to a plastic bottle recycling compression device. Background Technology

[0002] Plastic bottles are mainly made of materials such as polyethylene or polypropylene with the addition of various organic solvents. Plastic bottles widely use polyester, polyethylene, and polypropylene as raw materials. After adding the corresponding organic solvents, they are heated at high temperatures and then molded into plastic containers through plastic molds by blow molding, extrusion blow molding, or injection molding. Currently, for the recycling of plastic bottles, it is usually necessary to flatten the bottles by stepping on them or crushing them with a machine to release the air inside the bottles, thereby reducing the space occupied by the bottles during recycling, transportation, and storage, and making them easier to collect.

[0003] Referring to the existing patent publication number: CN214926144U, a waste plastic bottle and can recycling compression processing device includes a working box. A drive cylinder is installed at the top of the working box, and a drive piston is installed at the lower end of the drive cylinder. An alloy pressure plate is fixedly connected to the lower end of the drive piston through a drive rod. This utility model can quickly compress and shape waste plastic bottles by setting an automated extrusion drive mechanism, saving storage space and labor costs.

[0004] However, in actual use, existing recycling compression devices often have some residual water in the discarded bottles. During the crushing process, this residual water flows onto the machine as the bottles are crushed and degassed, causing it to leak out of the machine and contaminate the recycling area. It can even contaminate the bags or baskets containing the bottles, affecting the work of recycling workers. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a plastic bottle recycling and compression device. This invention incorporates a pressure needle within the device, which punctures the bottle during compression, allowing internal water to drain out. During compression and lifting, the centrifugal assembly rotates the bottle inside the filter cartridge, effectively separating residual water from the bottle and preventing contamination of the subsequent working environment.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A plastic bottle recycling compression device, comprising:

[0008] The main body of the device has an internal structure with space for compression processing;

[0009] A support plate is installed inside the main body of the device. The surface of the support plate has through-holes for water leakage. A water storage space is constructed between the lower part of the support plate and the main body of the device. A centrifugal assembly is constructed on the surface of the support plate.

[0010] A compression component that can be movably positioned in the vertical direction is installed inside the upper part of the main body of the device.

[0011] The present invention is further configured such that the centrifugal assembly includes: a motor, a filter cartridge, a lower pressure plate, and a through hole;

[0012] The motor is mounted on the surface of the support plate, the filter cartridge is mounted on the output end of the motor, the lower pressure plate is fixed inside the filter cartridge, and the through holes are arranged in a ring array on the surface of the lower pressure plate.

[0013] The present invention is further configured such that a cleaning part is installed on the outer surface of the filter cartridge via a connecting rod, and the cleaning part is in contact with the interior of the main body of the device.

[0014] The present invention is further configured such that a protective cover located outside the motor is installed between the support plate and the main body of the device, and the upper part of the support plate is configured as a downwardly curved arc.

[0015] The present invention is further configured such that the compression assembly includes: a hydraulic cylinder, a piston rod, a mounting part, an upper pressure plate, a pressure needle, and an elastic element;

[0016] The hydraulic cylinder is mounted on the surface of the main body of the device. The piston rod is connected to the output end of the hydraulic cylinder. The mounting part is fixed at the end of the piston rod away from the hydraulic cylinder. The upper pressure plate is mounted on the lower part of the mounting part through an elastic element. The pressure needle is connected to the lower part of the mounting part and passes through the upper pressure plate.

[0017] The present invention is further configured such that the upper pressure plate is in contact with the interior of the filter cartridge, and the pressure needles and through holes are arranged in a one-to-one correspondence.

[0018] The present invention is further configured such that a door is hinged to the surface of the main body of the device, and a drain pipe with a valve is connected to the lower part of the main body of the device.

[0019] The beneficial effects of this utility model are as follows: This utility model has a pressure needle inside the device, which can pierce the bottle when it is compressed, so that the water inside can flow out. When compressed and lifted, the bottle inside the filter cartridge can be rotated under the action of the centrifugal component, thereby fully separating the residual water inside from the bottle and avoiding pollution of the subsequent working environment.

[0020] 1. This plastic bottle recycling and compression device, through the cooperation of an elastic element and a pressure needle, compresses the recycled plastic bottles. As the hydraulic cylinder operates, it pushes the piston rod to gradually extend, thereby moving the upper pressure plate below into the filter cartridge to compress the plastic bottles. As the upper pressure plate continuously squeezes the plastic bottles, it also gradually compresses the elastic element. At this time, the pressure needle will extend from the upper pressure plate to puncture the plastic bottles, allowing the water inside to flow out and preventing it from remaining in the bottles and affecting the subsequent working environment. Furthermore, during the lifting process, the elastic element can push the upper pressure plate to reset, thus preventing plastic bottles from sticking to the pressure needle and improving the usage effect.

[0021] 2. This plastic bottle recycling and compression device, through the coordinated arrangement of a centrifugal component, connecting rod, and cleaning unit, allows the pressure needle to move into the through hole during bottle puncture and compression, providing operating space. After the compression component is raised, the centrifugal component operates, causing the motor to drive the filter cartridge, which in turn rotates the plastic bottles inside the filter cartridge, thus fully separating residual water. Simultaneously, the cleaning unit rotates with the filter cartridge via the connecting rod, cleaning the interior of the device. The device is easy to operate and reduces the labor intensity of personnel. Attached Figure Description

They are used only for the convenience of describing this patent and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this patent.

[0031] In the description of this patent, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0032] Reference Figure 1-5 A plastic bottle recycling compression device includes: a main body 1 with an internal compression processing space; a support plate 8 installed inside the main body 1, with drainage holes 9 through the surface of the support plate 8, and a water storage space between the lower part of the support plate 8 and the main body 1. The support plate 8 provides support for the installation of components and has a certain strength. Water generated during compression can flow into the water storage space below through the drainage holes 9, facilitating subsequent processing and discharge. The surface of the support plate 8 is also equipped with a centrifugal component, which helps to more effectively remove residual water and air from the plastic bottle during compression. A compression component is installed vertically and movable above the interior of the main body 1, which can compress plastic bottles placed inside the device through its vertical movement.

[0033] Specifically, refer to Figure 2-3The centrifugal assembly includes a motor 6, a filter cartridge 7, a lower pressure plate 10, and through holes 15. The motor 6 is mounted on the surface of a support plate 8, the filter cartridge 7 is mounted on the output end of the motor 6, the lower pressure plate 10 is fixed inside the filter cartridge 7, and the through holes 15 are arranged in a ring array on the surface of the lower pressure plate 10. In this embodiment, the motor 6, as the power source of the centrifugal assembly, is mounted on the surface of the support plate 8 and is responsible for driving the filter cartridge 7 to rotate, thereby generating centrifugal force to throw out water and other liquids from the plastic bottle. Due to the characteristics of the filter cartridge 7, the plastic bottle can remain inside, while the water can pass through the filter cartridge 7 for separation, improving the treatment effect. The lower pressure plate 10 and the through holes 15 can correspond to the compression assembly, providing a carrier for the compression of the plastic bottle. Through centrifugal dehydration, the water content in the plastic bottle can be significantly reduced, thereby improving the quality of recycled plastic.

[0034] Furthermore, a cleaning part 12 is installed on the outer surface of the filter cartridge 7 via a connecting rod 11, and the cleaning part 12 is in contact with the interior of the device body 1. Through this design, the connecting rod 11 ensures that the cleaning part 12 can move with the rotation of the filter cartridge 7. The cleaning part 12 is usually made of wear-resistant and corrosion-resistant materials, such as rubber, plastic or metal brush, and is tightly attached to the inner surface of the device body 1. It is used to remove residues, moisture or impurities adhering to the inner wall of the device when the filter cartridge 7 rotates, which helps to keep the device clean and hygienic.

[0035] Furthermore, a protective cover 5 is installed between the support plate 8 and the main body 1 of the device, located outside the motor 6. The upper part of the support plate 8 is curved downwards. With this design, the main function of the protective cover 5 is to protect the motor 6 from interference and damage from the external environment. During the plastic bottle recycling and compression process, there may be splashing fragments, water or other impurities. The protective cover 5 can effectively block these substances from entering the motor and prevent the motor from being damaged or malfunctioning. At the same time, under the action of the curved support plate 8, the separated water resources can be guided better and the water flow path can be optimized so that the water generated during the cleaning or compression process can flow more smoothly into the water storage space below through the drain hole 9.

[0036] Specifically, refer to Figure 2 , Figure 4 and Figure 5The compression assembly includes: a hydraulic cylinder 2, a piston rod 13, a mounting part 14, an upper pressure plate 16, a pressure needle 17, and an elastic element 18. The hydraulic cylinder 2 is mounted on the surface of the main body 1 of the device. The piston rod 13 is connected to the output end of the hydraulic cylinder 2. The mounting part 14 is fixed to the end of the piston rod 13 away from the hydraulic cylinder 2. The upper pressure plate 16 is mounted on the lower part of the mounting part 14 via the elastic element 18. The pressure needle 17 is connected to the lower part of the mounting part 14 and passes through the upper pressure plate 16. In this embodiment, the hydraulic cylinder 16 serves as the power source for the compression assembly. The cylinder 2 provides sufficient pressure to drive the piston rod 13 and the upper pressure plate 16 to perform compression operations. As the upper pressure plate 16 continuously squeezes the plastic bottle, it will also gradually compress the elastic element 18. At this time, the pressure needle 17 will extend from the upper pressure plate 16. The pressure needle 17 can penetrate the plastic bottle to help expel air and residual moisture from the bottle, thereby improving the compression effect. During the lifting process, the elastic element 18 can push the upper pressure plate 16 to reset, thereby preventing plastic bottles from sticking to the pressure needle 17 and improving the performance.

[0037] Furthermore, the upper pressure plate 16 is fitted to the interior of the filter cartridge 7, and the pressure needles 17 and through holes 15 are arranged in a one-to-one correspondence. With this design, when the upper pressure plate 16 is tightly fitted to the interior of the filter cartridge 7, it can be ensured that the plastic bottle or other compressed object is subjected to uniform and stable pressure during the compression process. The one-to-one correspondence between the pressure needles 17 and through holes 15 ensures that each plastic bottle or object can be accurately pierced, thereby releasing the internal gas or liquid and further promoting the compression process.

[0038] Furthermore, the surface of the main body 1 is hinged with a door 3, and the lower part of the main body 1 is connected to a drain pipe 4 with a valve. This design allows users to easily open and close the door 3, thereby facilitating the insertion of plastic bottles for compression and the removal of the compressed plastic blocks. The water resources separated by opening and closing the valve can be discharged from the drain pipe 4.

[0039] Working Principle: When using this invention, first open the door 3 and place the recycled plastic bottle into the filter cartridge 7. Then close the door 3 to activate the hydraulic cylinder 2. As the hydraulic cylinder 2 operates, it pushes the piston rod 13 to gradually extend, thereby moving the upper pressure plate 16 into the filter cartridge 7 to compress the plastic bottle. As the upper pressure plate 16 continuously squeezes the plastic bottle, it also gradually compresses the elastic element 18. At this time, the pressure needle 17 extends from the upper pressure plate 16 to puncture the plastic bottle, allowing the water inside to flow out and preventing it from remaining inside the bottle and affecting the subsequent working environment. Furthermore, the lifting mechanism... During the process, the elastic element 18 can push the upper pressure plate 16 to reset, thereby preventing plastic bottles from sticking to the pressure needle 17 and improving the usage effect. When piercing and compressing the bottle, the pressure needle 17 can move into the through hole 15 to provide operating space. After the compression component is lifted, the centrifugal component operates, which causes the motor 6 to drive the filter cartridge 7 to move, so that the plastic bottle inside the filter cartridge 7 can also rotate to a certain extent, thereby fully separating the residual water resources. At the same time, the cleaning part 12 can rotate together with the filter cartridge 7 through the connecting rod 11 to clean the inside of the device. The operation is convenient and reduces the labor intensity of personnel.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
