Description

Technical Field

[0001] The invention relates to the field of PET recycled plastic sheet processing, in particular to waste material recovery equipment used for PET recycled plastic sheet processing. Background Art

[0002] PET recycled plastic sheet is a sheet made by recycling and reprocessing waste PET materials (such as plastic bottles, food packaging, etc.). It has many advantages, mainly including environmental protection, resource conservation and good physical properties. With the widespread use of PET recycled plastic sheets, the amount of plastic waste generated is increasing. If these plastic wastes are not effectively recycled and processed, they will cause serious pollution to the environment, such as occupying land, polluting soil and water bodies, etc. Therefore, efficient recycling and processing equipment is needed to process a large amount of plastic waste. In the plastic recycling industry, in order to make the recycled plastics able to be used again, there are certain requirements for the quality of recycled plastics. The recycled plastics need to be cleaned as much as possible to remove impurities, dirt and other pollutants to meet the requirements of subsequent processing and reuse. When the existing plastic waste recycling equipment is used, the PET recycled plastic sheet waste is usually crushed by a crushing mechanism. The crushed plastic waste will fall into the cleaning net barrel, and then use The plastic waste in the cleaning net barrel is rinsed with a flushing mechanism, and during the flushing process, a driving source such as a motor is used to drive the cleaning net barrel to rotate, and then the flushing mechanism can be used for flushing, thereby providing a cleaning effect. However, a problem arises in this process. The weight of the crushed plastic waste is relatively low. Under the action of the rotation of the cleaning net barrel, the plastic waste in the cleaning net barrel is easy to bounce upward, resulting in the flushing mechanism being unable to effectively flush the plastic waste; secondly, moisture may remain on the surface of the plastic sheet waste after washing. If it is not dried, the moisture may cause pollution in the subsequent processing process or affect the bonding effect. Therefore, the washed plastic sheet waste needs to be dried, but the existing plastic waste recycling equipment cannot directly dry the washed plastic waste. The plastic waste needs to be discharged from the plastic waste recycling equipment and then dried using a drying equipment, which increases the workload of the operator. For this reason, we propose a waste recycling equipment for PET recycled plastic sheet processing. Summary of the invention

The sewage pipe 39 is located directly above the filter cartridge 38. When in use, the solenoid valve 40 is opened. Since the sewage pipe 39 is located directly above the filter cartridge 38, the water discharged from the sewage pipe 39 will fall directly into the filter cartridge 38.

[0039] The working principle of the present invention is as follows: before use, ensure that the moving block 1604 fits exactly with the two sets of limit rings 1605, and at this time, the two sets of bevel gears 1612 mesh with each other; when in use, pour an appropriate amount of PET recycled plastic sheet waste into the crushing box 21, and at the same time, start the servo motor 10 to drive the driving rod 5 to rotate, and the driving rod 5 rotates and drives the rotating rod 1611 to rotate under the transmission of the two sets of sprockets 17 and the chain 18, and the rotation of the rotating rod 1611 drives the rotating member 1608 to rotate, and the rotating member 1608 rotates and meshes with each other between the two sets. The rotation shaft 1609 is driven by the gear 1 1610, and the rotation of the rotation shaft 1609 and the transmission of the two sets of mutually meshing bevel gears 1612 drive the blocking roller 3 to rotate.

The two sets of mutually meshing gear wheels 23 drive the two groups of crushing rollers 22 to rotate. The rotation of the two groups of crushing rollers 22 can crush the PET recycled plastic sheet waste poured into the crushing box 21.

[0040] The crushed waste will fall into the feed pipe 1 and be blocked by the blocking roller 3. The waste in the feed pipe 1 will not fall directly into the cylindrical box 2. During the crushing process, the blocking roller 3 will also rotate. When the blocking roller 3 rotates, the position of the material trough 4 will be adjusted, so that the waste falling into the material trough 4 will fall into the cylindrical box 2. At the same time, the water pump 33 is started and the water in the water tank 31 is pumped into the nozzle 35 through the suction pipe 36 and the outlet pipe 34, and then sprayed out from the nozzle 35. The water sprayed from the nozzle 35 will pass through the circular filter plate 8 to rinse the waste in the cylindrical box 2, and during the rinsing process, the waste in the cylindrical box 2 is blocked by the blocking roller 3. will pop up; and during the cleaning process, the rotation of the driving rod 5 will drive the partition 6 to rotate, and the waste in the cylindrical box 2 will be separated by the distribution of the partition of the partition 6, and the rotation of the partition 6 will continuously adjust the position of the waste in the cylindrical box 2, so that the nozzle 35 can evenly wash the waste, and the sewage generated by the washing can pass through the circular filter plate 8 and finally be discharged from the sewage pipe 39.

[0041] When the flushing is completed, the water pump 33 is stopped, and then the flushing work is stopped. Then the electric push rod 1607 is started to drive the moving block 1604 to move until the moving block 1604 contacts the two sets of limit rings 1606. At this time, the two sets of bevel gears 1612 will disengage from each other. At this time, the blocking roller 3 and the two sets of crushing rollers 22 will stop working, and the auxiliary block 1613 will be inserted into the driving cylinder 1615. During the movement of the moving block 1604, the hexagonal rod at one end of the rotating member 1608 will slide along the inner side of the rotating rod 1 1611, and the hexagonal rod of the rotating member 1608 will not be separated from the rotating rod 1 1611. At this time, the rotation of the rotating rod 1 1611 will still drive the rotating member 1608 to rotate, and the rotation of the rotating member 1608 will drive the auxiliary block 1 613 rotates, and after the auxiliary block 1613 rotates and contacts the two groups of contact blocks 1616, it will drive the driving cylinder 1615 to rotate, and the driving cylinder 1615 rotation will drive the rotating rod 1614 to rotate, and the rotating rod 1614 rotates and under the transmission of the two groups of sprocket wheels 19 and the chain 20, it will drive the fan shaft 14 to rotate, and the rotation of the fan shaft 14 will drive the fan blades 15 to rotate, and the rotation of the fan blades 15 will generate wind, which can dry the waste in the cylindrical box 2, and the cylindrical box 2 is connected to the exhaust pipe 26 to ensure the circulation of wind, and in the process of drying, the partition 6 still rotates, and the rotation of the partition 6 will continuously adjust the position of the waste in the cylindrical box 2, so that the waste at different positions in the cylindrical box 2 can be evenly dried;

[0042] When the air drying work is completed, the servo motor 10 is stopped and the electric push rod 28 is started to drive the blocking plate 29 to move, so that the blocking plate 29 opens the discharge port 30. At this time, the waste in the cylindrical box 2 can be discharged through the discharge port. During the discharge process, the servo motor 10 can be appropriately started to drive the partition 6 to rotate and adjust the position of different partitions, so that the waste at different positions can be discharged.

[0043] It should be noted that when the present invention is in use, an external suitable power supply is required to provide power support for the operation of the servo motor 10, the electric push rod 28, the water pump 33, the electric push rod 1 1607 and the solenoid valve 40, and the servo motor 10, the electric push rod 28, the water pump 33, the electric push rod 1 1607 and the solenoid valve 40 all need to be connected to a suitable external controller to control the operation of the servo motor 10, the electric push rod 28, the water pump 33, the electric push rod 1 1607 and the solenoid valve 40.
