Description

Technical Field

[0002] Recycled colored PET staple fiber is a short fiber made from recycled colored PET bottles through processes such as washing and crushing. In the subsequent production process of recycled colored PET staple fiber, such as mixing and melting, it is necessary to feed the raw materials in conjunction with the feeding process.

[0003] Chinese Patent Application No. CN201822157512.5 provides a PET short fiber feeding system. This system involves setting up mounting base one and mounting base two on both sides of the production machinery, and installing the two ends of the claw roller on the top of mounting base one and mounting base two respectively. The claw roller at the entrance of the production machinery continuously pushes the short fiber inward, allowing the short fiber material to enter the conveyor belt inside the production machinery more quickly, reducing the blockage of the short fiber material at the inlet of the device, and improving the practicality of the device.

[0004] When using PET staple fiber feeding mechanisms, raw material feeding is mostly done manually or with a simple screw feeding device. However, this method cannot accurately control the amount of raw material fed, resulting in uneven fiber color and density, which affects the practicality of the quantitative feeding mechanism for recycled colored PET staple fibers. Therefore, a quantitative feeding mechanism for recycled colored PET staple fibers is proposed to address the above problems. Utility Model Content

After being conveyed, the fibers enter the weighing box, where a weight sensor at the bottom monitors the weight of the fibers in real time and feeds it back to the control system. This, in conjunction with the control valve, enables precise control of the feeding speed and amount. Furthermore, a conveying structure is also provided inside the weighing box, allowing the quantitative feeding mechanism for recycled colored PET short fibers to achieve both smooth and precise feeding, thus improving the practicality of the quantitative feeding mechanism for recycled colored PET short fibers.

[0024] The following is in conjunction with the appendix Figure 1-5This application will be described in further detail.

[0025] This application discloses a quantitative feeding mechanism for recycled colored PET staple fibers. (See also...) Figures 1-5 A quantitative feeding mechanism for recycled colored PET short fibers includes a hopper 1; a processing box 2 is fixedly connected to the bottom of the hopper 1, a weighing box 14 is movably connected to the bottom of the processing box 2, a reinforcing frame 15 is fixedly connected to the outer end of the weighing box 14, support rods 16 are fixedly connected to both ends of the reinforcing frame 15, a weight sensor 17 is installed at the bottom of the support rod 16, a connecting rod 11 is rotatably connected to the inner end of the processing box 2, and a ring-shaped dispersing rod 12 is fixedly connected to the outer end of the connecting rod 11. By installing the weighing box 14 and the dispersing rods 12, when the feeding mechanism is running, the multiple dispersing rods 12 rotate with the drive of the motor 10, from... The short fiber raw material inside the processing box 2 can be pre-processed, broken up, and loosened to prevent the short fibers from tangling and clumping during feeding and conveying. After being conveyed, it enters the weighing box 14. The weight sensor 17 at the bottom of the weighing box 14 monitors the weight of the fibers in the weighing box 14 in real time and feeds it back to the control system. Together with the control valve 13, it can accurately control the feeding speed and feeding amount. The weighing box 14 is also equipped with a conveying structure, which allows the quantitative feeding mechanism of the recycled colored PET short fiber to achieve smooth feeding and more precise feeding, thus improving the practicality of the quantitative feeding mechanism of the recycled colored PET short fiber.

[0026] Reference Figures 1-3 Motor 2 10 is installed at the rear end of the processing box 2. Connecting rod 11 is connected to motor 2 10. Motor 1 7 is fixedly connected to the upper rear end of the processing box 2. By installing motor 1 7 and motor 2 10, motor 1 7 and motor 2 10 are installed at the rear end of the processing box 2, making it easier for motor 1 7 and motor 2 10 to dissipate heat during operation.

[0027] Reference Figure 2 and Figure 3 The transmission end of motor 7 is fixedly connected to a stirring rod 8, and the outer end of the stirring rod 8 is fixedly connected to multiple symmetrically distributed blades 9. By installing the stirring rod 8 and the blades 9, when the mechanism is feeding, motor 10 starts to make the stirring rod 8 and the multiple blades 9 rotate and stir. With the help of the dispersing rod 12, the mechanism can continuously stir during feeding, ensuring smooth fiber feeding, which is beneficial to the uniformity of subsequent processing, reducing mechanical wear and failure caused by material jamming, and further improving the feeding effect of the feeding mechanism.

[0028] Reference Figure 1 and Figure 2The bottom of the processing box 2 is fixedly connected to the discharge pipe 3. The outer end of the discharge pipe 3 is equipped with a control valve 13. By installing the control valve 13, the control valve 13 can be connected to the control system as a signal. When the controller receives the weight value set according to the weight value, it controls the control valve 13 to start, so that the processing box 2 and the discharge pipe 3 can conveniently discharge materials.

[0029] Reference Figure 1 The processing box 2 is fixedly connected to both ends of the support frame 4, and the outer ends of the support frame 4 are fixedly connected to the bracket 5. The bottom end of the bracket 5 is fixedly connected to the base 6. By installing the support frame 4 and the bracket 5, the support frame 4 can form a support structure at both ends of the processing box 2. Together with the bracket 5, the overall structure of the mechanism is more stable.

[0030] Reference Figure 1 and Figure 3 The bottom of the weight sensor 17 is equipped with a support frame 18, which is fixedly connected to the inner end of a pair of brackets 5. The bottom of the weighing box 14 is fixedly connected with a feeding assembly 19, and the bottom of the feeding assembly 19 is equipped with a feeding pipe 20. The outer end of the feeding pipe 20 is fixedly connected with a motor 21. By installing the support frame 18, which is located at the inner end of a pair of brackets 5, the weight sensor 17 and the connected weighing box 14 can operate more stably.

[0031] Reference Figure 1 and Figure 5 The drive end of the motor 21 is fixedly connected to a screw conveyor 22, and the front end of the feeding pipe 20 is fixedly connected to a feeding head 23. By installing the screw conveyor 22, the screw conveyor 22 rotates under the drive of the motor 21, so that the raw material fed from the weighing box 14 can be conveniently transferred and fed.

[0032] Working principle: When using this mechanism, short fiber raw materials first enter the processing box 2 from the feed hopper 1. Multiple dispersing rods 12 inside the processing box 2 rotate under the drive of motor 10, thereby initially dispersing and loosening the short fiber raw materials inside the processing box 2. Motor 10 starts to rotate the stirring rod 8 and multiple blades 9 to stir. Together with the dispersing rods 12, the mechanism can continuously stir during feeding, ensuring smooth fiber feeding and promoting uniformity in subsequent processing. It also reduces mechanical wear and malfunctions caused by material jamming. After being conveyed, the fiber enters the weighing box 14. The weight sensor 17 at the bottom of the weighing box 14 monitors the weight of the fiber in the weighing box 14 in real time and feeds it back to the control system. Together with the control valve 13, it can accurately control the feeding speed and feeding amount. The weighing box 14 also has a conveying structure inside, which allows the quantitative feeding mechanism of the recycled colored PET short fiber to achieve smooth feeding and more precise feeding.

[0033] Finally, the raw material enters the feeding pipe 20. The spiral conveyor 22 inside the feeding pipe 20 rotates under the drive of the motor 21, so that the raw material discharged from the weighing box 14 can be conveniently transferred and fed.
