Description

Technical Field

[0001] This utility model belongs to the field of polyester production and conveying technology, specifically a modified polyester chip crystallization and drying equipment with a quantitative feeding mechanism. Background Technology

[0002] The polyester (PET) industry, as one of our company's important pillar industries, has experienced rapid development in recent years. However, the production process generates a large amount of polyester chip waste, including scraps, waste fibers, and waste blocks. Directly discarding this waste not only results in serious resource waste but also pollutes the environment. Polyester processing requires pretreatment of the polyester chip waste, including sorting, washing, crushing, and drying. The polyester is then fed into the polyester chip crystallization and drying equipment via a feeding mechanism. However, existing feeding mechanisms, which feed the polyester into the crystallization and drying equipment through a conveyor belt or inlet, lack quantitative feeding capabilities, leading to blockages in the conveyor pipes during feeding. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a modified polyester chip crystallization and drying device with a quantitative feeding mechanism. This solves the problem that existing feeding mechanisms feed polyester into the crystallization and drying device through a conveyor belt or inlet, but such feeding mechanisms lack quantitative functions, which leads to blockage of the conveying pipe during feeding.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a modified polyester chip crystallization and drying device with a quantitative feeding mechanism, comprising a conveying pipe, an inlet on the top surface of the conveying pipe, a feed pipe fixedly connected to the surface of the conveying pipe corresponding to the feed inlet, a storage box fixedly connected to the top of the feed pipe, a distribution box fixedly connected to the top of the storage box, the distribution box communicating with the storage box, a distribution wheel rotatably connected to the bottom of the distribution box via a bearing, one end of the distribution wheel penetrating the distribution box and fixedly connected to a connecting gear, a connecting gear meshing on one side of the connecting gear, a side of the connecting gear rotatably connected to one side of the distribution box via a bearing, an installation box fixedly connected to one side of the distribution box, a rotary motor fixedly connected inside the installation box, the output end of the rotary motor fixedly connected to one side of the connecting gear, and a motor protective shell fixedly connected to one side of the conveying pipe.

[0005] As a further embodiment of this utility model: a servo motor is fixedly connected inside the motor protective shell, and the output end of the servo motor is fixedly connected to an output auger through the conveying pipe, and the output auger is rotatably connected to the inside of the conveying pipe through a bearing.

[0006] As a further embodiment of this utility model: one end of the conveying pipe is fixedly connected to the main body of the crystallization drying equipment, and the bottom of the conveying pipe is fixedly connected to two support legs.

[0007] As a further embodiment of this utility model: the top of the material distribution box is rotatably connected to a rotating cover via a pin, and a plug is fixedly connected to one side of the rotating cover.

[0008] As a further embodiment of this utility model: a mounting box is fixedly connected to the top of one side of the material distribution box corresponding to the insert block, and a limiting groove is provided in the mounting box.

[0009] As a further embodiment of this utility model: a plug rod is slidably connected through the limiting groove, and the top of the plug rod extends through the limiting groove to the outside of the mounting box and is inserted into the plug block.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This modified polyester chip crystallization and drying equipment with a quantitative feeding mechanism is equipped with a dispensing box, a rotary motor, a connecting gear, and a dispensing wheel. First, the polyester is placed into the dispensing box. Then, the rotary motor is started to drive the connecting gear to rotate. The connecting gear then drives the connecting gear and the dispensing wheel to rotate. When the dispensing wheel rotates, the gap at the top of the dispensing wheel is filled with polyester and rotates, carrying the polyester from the gap into the storage box. Then, the polyester is discharged into the conveying pipe through the storage box and the feed pipe. At this time, the servo motor is started to drive the output auger to rotate and convey the polyester. By controlling the speed of the rotating dispensing wheel, the polyester is quantitatively conveyed, preventing the polyester from accumulating in large quantities and causing blockages. 2. This modified polyester chip crystallization and drying equipment with a quantitative feeding mechanism, by setting a rotating cover and an insert rod, when it is necessary to close the rotating cover on the top of the distribution box, the rotating cover can be rotated to the top of the distribution box. At this time, the insert rod can be lifted and moved to the top, inserted into the top of the insert block, and then the insert rod is rotated to the inside of the limiting slide groove for locking and fixing. This locks the rotating cover onto the top of the distribution box, thereby preventing dust and other impurities from entering the distribution box and causing contamination of the polyester raw materials inside the distribution box.

[0012] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0013] like Figure 1-3 As shown, this utility model provides a technical solution: a modified polyester chip crystallization and drying equipment body 15 with a quantitative feeding mechanism, including a conveying pipe 1, a feed inlet 2 is opened on the top of the surface of the conveying pipe 1, a feed pipe 3 is fixedly connected to the surface of the conveying pipe 1 at the position corresponding to the feed inlet 2, a storage box 4 is fixedly connected to the top of the feed pipe 3, a distribution box 5 is fixedly connected to the top of the storage box 4, the distribution box 5 is connected to the storage box 4, and a distribution wheel 10 is rotatably connected to the bottom of the distribution box 5 through a bearing. By using the gap of the distribution wheel 10, the polyester in the gap at the top of the distribution wheel 10 is rotated to the bottom by rotating the distribution wheel 10, and the polyester at the top is rotated and quantitatively fed into the storage box 4 in batches. One end of the material distribution wheel 10 passes through the material distribution box 5 and is fixedly connected to a connecting gear 9. A connecting gear 8 meshes with one side of the connecting gear 9. One side of the connecting gear 8 is rotatably connected to one side of the material distribution box 5 through a bearing. A mounting box 6 is fixedly connected to one side of the material distribution box 5. A rotary motor 7 is fixedly connected inside the mounting box 6. The rotary motor 7 drives the connecting gear 8 and the connecting gear 9 to rotate, so that the connecting gear 9 can synchronously drive the material distribution wheel 10 to rotate. The output end of the rotary motor 7 is fixedly connected to one side of the connecting gear 8. A motor protective shell 11 is fixedly connected to one side of the conveying pipe 1. A servo motor 12 is fixedly connected inside the motor protective shell 11. The output end of the servo motor 12 passes through the conveying pipe 1 and is fixedly connected to the output auger 13. The output auger 13 is rotatably connected to the inside of the conveying pipe 1 through a bearing. By setting up the servo motor 12 and the output auger 13, the servo motor 12 drives the output auger 13 to rotate, and the rotation of the output auger 13 conveys the polyester in the conveying pipe 1. One end of the conveying pipe 1 is fixedly connected to the main body 15 of the crystallization drying equipment, and two support legs 14 are fixedly connected to the bottom of the conveying pipe 1. By setting the support legs 14, the conveying pipe 1 is supported, thereby preventing the conveying pipe 1 from contacting the ground and causing impurities on the ground to contaminate the conveying pipe 1. The top of the material distribution box 5 is rotatably connected to a rotating cover 16 via a pin. A plug 20 is fixedly connected to one side of the rotating cover 16. A mounting box 17 is fixedly connected to the top of the side of the material distribution box 5 corresponding to the plug 20. A limiting groove 18 is provided in the mounting box 17. A plug rod 19 is slidably connected through the limiting groove 18. The top of the plug rod 19 extends through the limiting groove 18 to the outside of the mounting box 17 and is inserted into the plug 20. By setting the plug rod 19, the plug 20 and the rotating cover 16 are limited by the plug rod 19.

[0014] The working principle of this utility model is as follows: First, polyester is placed into the dispensing box 5. After placement, the rotating cover 16 is placed into the dispensing box 5. At this time, the insert rod 19 is lifted and inserted into the top insert block 20. Then, the insert rod 19 is rotated to limit its position, thereby fixing the rotating cover 16 to the top of the dispensing box 5. When it is necessary to convey the polyester, the rotary motor 7 can be started. The output end of the rotary motor 7 drives the connecting gear 8 to rotate. At this time, the connecting gear 8 will synchronously drive the meshing connecting gear 9 to move forward. The rotating gear 9 drives the material distribution wheel 10 to rotate. When the material distribution wheel 10 rotates, it will rotate and transfer the polyester located in the gap at the top of the material distribution wheel 10 to the bottom storage box 4. Then, the polyester is discharged into the conveying pipe 1 through the storage box 4 and the feed pipe 3. At this time, the servo motor 12 can be started. The output end of the servo motor 12 drives the output auger 13 to rotate. Then, the output auger 13 conveys the polyester in the conveying pipe 1 and delivers the polyester into the main body 15 of the crystallization drying equipment.
