Description

Technical Field

[0001] The invention relates to the technical field of plastic material recycling, in particular to an environmentally friendly plastic material recycling device. Background Art

[0002] With the widespread use of plastic products in daily life and industrial production, the amount of plastic waste is also increasing. If these plastic wastes are not effectively recycled, they will not only cause serious pollution to the environment, but also waste a lot of resources. Therefore, a new type of environmentally friendly plastic material recycling and reuse device is needed to solve these problems.

[0003] The recycling steps of existing recycling devices are mostly to first break the plastic material into small pieces, then wash and dry the small pieces of plastic, and finally heat and melt the clean small pieces of plastic, and extrude them into plastic products of various shapes through a mold;

[0004] However, the existing recycling and reuse devices complete these steps in a unified manner and cannot be stopped at will in the middle. In particular, the steps of cleaning and drying the crushed small pieces of plastic can only be processed in batches. If new materials are added in the middle, the new and old materials will be mixed, the cleaned materials will be contaminated again, and the dried materials will be wet, disrupting the normal steps. However, processing materials in batches cannot maximize the efficiency of the device. For example, when it comes to the drying stage, the previous crushing and cleaning are in a stopped state, which greatly reduces the working efficiency of the device and the productivity is low. In addition, it cannot be stopped or increased in time according to the demand for new plastic products, making operation difficult. Summary of the invention

[0035] The discharge bin 9 is located in the inner cavity of the processing box 1, and there are four groups of discharge bins 9. The four groups of discharge bins 9 are distributed in a circular array up and down, left and right, and the interval angle between each group of discharge bins 9 is 90 degrees. The four upper and lower surfaces of the discharge bin 9 are surfaces with gaps formed by round rods 29, and there is no round rod 29 in the middle position of the upper and lower surfaces of the discharge bin 9 to form an opening for feeding and discharging materials. The four groups of discharge bins 9 rotate clockwise.

[0036] A motor 25 is fixedly connected to the bottom of the inner cavity of the processing box 1 and below the two sides of the rotating cylinder 5. The output end of the motor 25 is fixedly connected to a rotating rod 26. The top of the rotating rod 26 is fixedly connected to a rotating plate 27.

[0038] The motor 25 rotates to drive the rotating rod 26 to rotate, the rotating rod 26 rotates to drive the rotating plate 27 to rotate, the rotating plate 27 rotates to drive the toggle rod 28 to rotate, and the toggle rod 28 rotates to drive the four groups of discharge bins 9 to make intermittent motion at an angle of 90 degrees. At this time, the first hydraulic cylinder 12 of the uppermost discharge bin 9 drives the moving plate 13 to open to receive the small pieces of plastic crushed by the crushing box 2. The four groups of discharge bins 9 make intermittent motion, and different treatments can be performed on the small pieces of plastic received in different discharge bins 9. New materials can be added and processed at any time, which is convenient and efficient.

[0039] The inner cavity of the material control pipe 4 is provided with a control valve, which can be opened or closed according to the time of intermittent movement to control the feeding of materials.

[0040] Four groups of second hydraulic cylinders 14 are fixedly connected to the bottom of the processing box 1, and the telescopic ends of the four groups of second hydraulic cylinders 14 are rotatably connected to a rotating part 15. One end of the rotating part 15 is movably connected to a cleaning tank 16. The cleaning tank 16 is located directly below the lower discharge bin 9 in the four groups of discharge bins 9, and cleaning liquid is placed in the cleaning tank 16.

[0041] The discharge bin 9 at the bottom is located in the inner cavity of the cleaning pool 16 and is soaked in the cleaning fluid. At this time, the four groups of second hydraulic cylinders 14 extend and contract to drive the cleaning pool 16 to shake and make the cleaning fluid shake, thereby cleaning the material in the discharge bin 9. The operation is simple. As long as the discharge bin 9 is rotated to the bottom, it can be cleaned and recycled.

[0042] Two groups of mounting plates 17 are fixedly connected to the inner wall of the processing box 1, and a fan 18 is fixedly connected to the top of the mounting plate 17. One side of the fan 18 is connected to an air inlet pipe 19. One end of the air inlet pipe 19 away from the fan 18 passes through the inner wall of the processing box 1 and extends to the outside of the processing box 1. The other side of the fan 18 is connected to an air outlet pipe 20. One end of the air outlet pipe 20 is connected to an enlarged nozzle 21, which faces the discharge bin 9 on the left side of the four groups of discharge bins 9.

[0043] A feed bin 23 is provided on the inner wall of the processing box 1. The feed bin 23 passes through the inner wall of the processing box 1 and one end extends to the inner cavity of the processing box 1, and the other end extends to the outside of the processing box 1. The end of the feed bin 23 extending to the inner cavity of the processing box 1 is connected to a receiving hopper 22. The receiving hopper 22 is located directly below the left discharge bin 9 among the four groups of discharge bins 9. The end of the feed bin 23 extending to the outside of the processing box 1 is connected to a hot melt bin 24.

[0044] When the discharge bin 9 rotates from the bottom to the left, the fan 18 draws air through the air inlet pipe 19 and blows the air into the discharge bin 9 through the air outlet pipe 20 to dry the material in the discharge bin 9. At the same time, the nozzle 21 can increase the diffusion area of ​​the air blown out of the air outlet pipe 20 so that the entire discharge bin 9 can be blown and dried. The dried material leaks out from the bottom of the discharge bin 9, passes through the receiving hopper 23, enters the feed bin 22, and finally goes to the hot melt bin 24 for processing, thereby realizing rapid drying and transportation.

[0045] The discharge bin 9 on the far right serves to store more broken small plastics. At the same time, when the discharge bin 9 on the far left is discharged and dried, the subsequent drying wind will continue to blow toward the discharge bin 9 on the far right, blowing off the dust and impurities on the materials in the discharge bin 9 on the far right, and pre-treating the materials in the discharge bin 9 on the far right for cleaning.

[0046] Working principle: First, the plastic is put into the crushing box 2 through the feed inlet 3, and the crushing box 2 is used for crushing. Then, the material is transported to the inner cavity of the processing box 1 through the material control pipe 4, and falls into the discharge bin 9 just above. Then, the first hydraulic cylinder 12 of the uppermost discharge bin 9 drives the moving plate 13 to close, and receives the small pieces of plastic crushed by the crushing box 2. The rotation of the motor 25 drives the rotating rod 26 to rotate, and the rotation of the rotating rod 26 drives the rotating plate 27 to rotate. The rotation of the rotating plate 27 drives the toggle rod 28 to rotate. The rotation of the toggle rod 28 drives the four groups of discharge bins 9 to make intermittent movements at an angle of 90 degrees. When the material is received at the top, it is rotated to the top. The discharge bin 9 at the bottom is located in the inner cavity of the cleaning pool 16 and is soaked in the cleaning liquid. At this time, the four groups of second hydraulic cylinders 14 extend and shorten to drive the cleaning pool 16 to shake and make the cleaning liquid shake, so as to clean the material in the discharge bin 9. When the discharge bin 9 rotates from the bottom to the left, the fan 18 draws air through the air inlet pipe 19 and blows the air into the discharge bin 9 through the air outlet pipe 20 to dry the material in the discharge bin 9. At the same time, the enlarged nozzle 21 can increase the diffusion area of ​​the air blown out of the air outlet pipe 20 so that the entire discharge bin 9 can be blown and dried. The dried material leaks out from the bottom of the discharge bin 9, enters the feed bin 22 through the receiving hopper 23, and finally reaches the hot melt bin 24 for processing.
