Description

Technical Field

[0001] This utility model relates to the field of waste plastic technology, specifically a compression device for waste plastic recycling and processing. Background Technology

[0002] Waste plastic is a colloquial term and does not refer to discarded, old, or useless plastic products. The vast majority of plastic products, especially those used in large quantities for single purposes, do not undergo significant changes in the properties of the plastic material itself after use. Therefore, they can be recycled and reprocessed into new plastic products for reuse. However, processing is necessary before reuse to achieve the goal of recycling.

[0003] CN218905983U discloses a waste plastic recycling and crushing device, including a crushing barrel. A compression plate is fixedly connected inside the crushing barrel, and a cylinder is located on the outer wall of the crushing barrel. A push plate is located at the output end of the cylinder. A crushing mechanism is installed inside the crushing barrel, and a filter plate is located at the bottom of the crushing mechanism. A rotating component is driven inside the crushing barrel, and a discharge port is located at the other end of the filter plate. A feeding cylinder is located on the outer wall of the crushing barrel at the discharge port. This invention drives the rotating component to rotate, thereby continuously vibrating the filter plate. This facilitates the collection of qualified plastics into a collection box and discharges unqualified plastics into the feeding cylinder. Driven by a feeding screw, the unqualified plastics are then discharged back to the crushing mechanism, improving the overall crushing efficiency and ensuring the uniformity of crushing, facilitating subsequent processing by workers.

[0004] However, the existing technology described above uses two cylinders to push two push plates relative to each other when compressing waste plastics to facilitate subsequent rapid crushing. This compression method results in residual stress in the compressed waste plastics, with a re-expansion rate of over 10% after compression. Furthermore, higher pressure and longer holding time are required for shaping, resulting in poor compression and shaping effect on waste plastics.

[0005] Therefore, a compression device for recycling and processing waste plastics is proposed to solve the problems mentioned above. Utility Model Content

[0006] To address the shortcomings of existing technologies, this utility model provides a compression device for waste plastic recycling and processing. It can solve the problem that the waste plastic blocks have a high re-expansion rate due to residual stress, which in turn requires higher pressure and longer holding time to shape the waste plastic blocks, resulting in poor compression and shaping effect of waste plastics.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a compression device for waste plastic recycling and processing, comprising a frame assembly, a compression assembly, and a crushing assembly.

[0014] Compared with the prior art, this utility model provides a compression device for recycling and processing waste plastics, which has the following beneficial effects:

[0015] 1.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0025] Please see Figure 1 - Figure 6 This embodiment of a compression device for recycling and processing waste plastics includes a frame assembly, a compression assembly, and a crushing assembly. The frame assembly includes a lower plate 1, an upper plate 2, and a top frame 3. The crushing assembly is disposed on the lower plate 1, and the compression assembly is disposed between the upper plate 2 and the top frame 3. The compression assembly includes a compression mold 7 and a pressure plate 9. A heat groove is formed at the lower end of the pressure plate 9, and an electric heating plate is fixedly installed in the heat groove. A wire hole 10 communicating with the heat groove is formed at the upper end of the pressure plate 9. A compression outlet 17 is formed on the side wall of the compression mold 7. The compression mold 7 has a first electric push rod 15 on its side wall. The inner wall of the compression mold 7 has a push groove, and a push block 16 is set in the push groove. The telescopic end of the first electric push rod 15 is fixedly connected to the side wall of the push block 16. The upper end of the upper plate 2 has a mounting hole 6. The compression mold 7 is fixedly installed in the mounting hole 6. The upper end of the top frame 3 is fixedly installed with a hydraulic cylinder 8. The telescopic end of the hydraulic cylinder 8 is fixedly connected to the upper end of the pressure plate 9. The lower plate 1 has a temperature controller. The temperature controller is electrically connected to the electric heating plate in the hot tub through the wire hole 10.

[0026] After placing the waste plastic into the compression mold 7, the hydraulic cylinder 8 is activated and its telescopic end pushes the pressure plate 9 downward. When the lower end of the pressure plate 9 contacts the waste plastic, the electric heating plate in the hot groove is activated. The electric heating plate heats and softens the waste plastic. Then the pressure plate 9 is pressed down. The softened waste plastic fully fills the interior of the compression mold 7 under the pressure of the pressure plate 9. The temperature controller set on the outside of the lower plate 1 can accurately adjust the temperature of the electric heating plate to prevent the plastic material inside the waste plastic from overheating and degrading. The pressure required for compression is reduced after the plastic is heated and softened and then pressed down, which increases the density of the compressed waste plastic block, making it less prone to loosening and resulting in a better compression and shaping effect.

[0027] The first electric push rod 15 pushes the pusher block 16 through the telescopic end, so that the pusher block 16 pushes the compressed and shaped waste plastic block towards the compression outlet 17, thereby compressing the waste plastic block and pushing it out of the compression mold 7 to complete demolding. No manual handling is required, saving time and effort.

[0028] The crushing assembly includes a crusher 18. A discharge hole is provided at the upper end of the lower plate 1. The crusher 18 is fixedly installed on the upper end face of the lower plate 1, and the discharge port of the crusher 18 is located in the discharge hole.

[0029] By setting up a crushing component, the heated compressed waste plastic blocks enter the crushing component. The uniformly dense compressed waste plastic blocks are subjected to more balanced force in the crusher 18, resulting in higher cutting efficiency and less likelihood of jamming.

[0030] Among them, four first pillars 19 are provided between the lower plate 1 and the upper plate 2, and second pillars 20 are fixedly connected to the four corners of the lower end of the lower plate 1. The top frame 3 is fixedly connected to the upper end surface of the upper plate 2.

[0031] By setting the first pillar 19, the lower layer 1 and the upper layer 2 can be stably connected by the four first pillars 19. By setting the four second pillars 20, the bottom surface of the lower layer 1 can be lifted off the ground.

[0032] Among them, the upper end face of the top frame 3 is inserted with the feed hopper 4, the side wall of the top frame 3 is fixedly installed with the second electric push rod, the telescopic end of the second electric push rod is fixedly connected with the inclined guide hopper 5, and the bottom end face of the inclined guide hopper 5 is slightly higher than the top surface of the compression mold 7.

[0033] By setting up a feeding hopper 4, a second electric push rod, and an inclined guide hopper 5, when waste plastic needs to be added to the compression mold 7, the waste plastic enters the compression mold 7 from the feeding hopper 4. Before the pressure plate 9 starts to press down, the second electric push rod pushes the waste plastic to the front of the compression mold 7, so that the waste plastic fed through the feeding hopper 4 is put into the compression mold 7 under the guidance and conveying of the inclined guide hopper 5. After a certain amount of waste plastic is filled into the compression mold 7, the second electric push rod retracts the inclined guide hopper 5 to avoid obstructing the normal pressing down of the pressure plate 9.

[0034] The compression mold 7 has a side plate hole 13 on its upper end face, which is connected to the compression outlet 17. An electric telescopic cylinder 11 is fixedly installed on the upper end face of the top frame 3. The telescopic end of the electric telescopic cylinder 11 passes through the side wall of the top frame 3 and is fixedly connected to a connecting rod 12. The lower end of the connecting rod 12 is fixedly connected to a side guard plate 14, which matches the compression outlet 17. An exhaust hole is opened at the lower end of the compression mold 7.

[0035] By opening the side plate hole 13 and setting the side guard plate 14, before the waste plastic enters the compression mold 7, the telescopic end of the electric telescopic cylinder 11 pushes the side guard plate 14 downward through the connecting rod 12, so that the side guard plate 14 descends in the side plate hole 13 and blocks the compression outlet 17. By opening the exhaust hole, the gas generated during the compression of waste plastic can be effectively discharged, preventing air bubbles or cracks inside the waste plastic compressed block.

[0036] Among them, the side wall of the top frame 3 is provided with a storage groove that matches the inclined guide bucket 5, and the side wall of the inclined guide bucket 5 is slidably connected to the inner wall of the storage groove.

[0037] By creating a storage slot, the inclined guide bucket 5 can enter the storage slot during horizontal displacement to avoid collision with the pressure plate 9.

[0038] A collection box is provided below the discharge hole of the lower plate 1;

[0039] By setting a collection box below the lower plate 1, the compressed waste plastic blocks can be crushed by the crushing component and then enter the collection box below through the discharge port and discharge hole, making it convenient for staff to collect and centrally process the crushed plastic fragments.

[0040] The working principle of the above embodiment is as follows: When in use, after placing the waste plastic into the compression mold 7, the hydraulic cylinder 8 is activated and its telescopic end pushes the pressure plate 9 downward. When the lower end of the pressure plate 9 contacts the waste plastic, the electric heating plate in the hot groove is activated. The electric heating plate heats and softens the waste plastic. Then the pressure plate 9 is pressed down. The softened waste plastic fully fills the interior of the compression mold 7 under the pressure of the pressure plate 9. The temperature controller set outside the lower plate 1 can accurately adjust the temperature of the electric heating plate to prevent the plastic material inside the waste plastic from overheating and degrading. The pressure required for compression is reduced after the plastic is heated and softened and then pressed down, which increases the density of the compressed waste plastic block, making it less prone to loosening and resulting in a better compression and shaping effect.

[0041] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
