Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of feeding machine technology, and more specifically, to a feeding machine for an electrostatic sorting machine for clean plastic sheets. Background Technology

[0002] In the process of electrostatic sorting of clean plastic sheets using an electrostatic separator, the feeder, as the starting point of the entire process, directly affects the accuracy and efficiency of subsequent sorting work. Among them, the height setting of the feeder's discharge port plays a key role in whether the material can enter the electrostatic separator accurately and stably.

[0003] Traditional electrostatic sorting machines for clean plastic sheets often have a fixed discharge port height. When faced with electrostatic sorting machines of different models and specifications, this fixed discharge port height cannot meet the diverse docking requirements. For example, CN103496136A discloses a new type of scraper-type feeder for plastic sheets, which consists of a frame, a conveying trough, a drive motor, a transmission chain, and scrapers. The conveying trough is inclined and fixed on the frame. A transmission chain that rotates cyclically is installed in the conveying trough through a sprocket. The transmission chain is driven by the drive motor through the sprocket. Scrapers are fixedly installed at intervals on the transmission chain. The scrapers consist of a vertical plate and a horizontal plate located on the front surface of the vertical plate.

[0004] The aforementioned existing technologies generally use chains and scrapers to transport materials during the plastic sheet processing, which is not convenient for adjusting the discharge port of the entire feeder according to different feed ports, resulting in poor applicability. Utility Model Content

[0022] Based on the above scheme, the first rotating mechanism includes:

[0023] A first gear is rotatably mounted on the lifting block, and a second connecting rod is fixedly provided between the first gear and the second bevel gear.

[0024] The second gear is rotatably mounted on the lifting block and meshes with the first gear.

[0050] like Figures 1-4 The diagram illustrates a feeding mechanism for an electrostatic sorting machine for clean plastic sheets according to an embodiment of this disclosure. It includes a frame 1, a scraper conveyor body 2 installed within the frame 1, a feeding bin 3 and a discharging bin 4 mounted on the frame 1, a base 5, a support frame 7, a lifting block 9, a positioning groove 12, a lifting mechanism, and a positioning mechanism. The base 5 is located on one side of the frame 1, and a hinge seat 6 is mounted on the base 5. The hinge end of the hinge seat 6 is fixedly connected to the frame 1. The support frame 7 is fixedly mounted on the base 5, and a support cover 8 is fixedly mounted on the support frame 7. The lifting block 9 is slidably disposed within the support cover 8, and a positioning frame 10 is fixedly mounted on the lifting block 9. A positioning frame 10 is fixedly mounted on the side wall of the positioning frame 10 near the lifting block 9. Positioning column 11 and positioning groove 12 are provided on two opposite side walls of frame 1. Positioning column 11 extends into positioning groove 12 and is adapted to the shape of positioning groove 12. Lifting mechanism is set between lifting block 9 and support frame 7 to drive lifting block 9 to move within support cover 8. Positioning mechanism is set on positioning frame 10 to position between positioning frame 10 and frame 1. Specifically, the operator places base 5 on one side of electrostatic separator. The operator can add material into frame 1 through feeding bin 3. Then, the plastic sheet is conveyed by scraper conveyor body 2. Afterward, plastic sheet can be added into electrostatic separator through discharge bin 4.

[0051] Reference Figures 2-4The lifting mechanism includes a first threaded rod 13 and a first motor 14. The first threaded rod 13 is rotatably mounted on the support frame 7 and extends into the lifting block 9 through a threaded engagement. The first motor 14 is mounted on the support frame 7, and the output end of the first motor 14 is fixedly connected to the first threaded rod 13. Specifically, the operation of the first motor 14 can drive the first threaded rod 13 to rotate. At the same time, through the threaded engagement between the first threaded rod 13 and the lifting block 9, the lifting block 9 can drive the positioning frame 10 and the positioning column 11 to move. Thus, through the engagement between the positioning column 11 and the positioning groove 12, the frame 1 can be angled, thereby facilitating the adjustment of the height of the discharge bin 4 on the frame 1.

[0052] Reference Figure 3 and Figure 4 The positioning mechanism includes a first cavity 15, a fixed column 16, and a moving mechanism. The positioning frame 10 has first cavities 15 on both sides of the lifting block 9. The positioning column 11 has a fixing port communicating with the first cavity 15. The fixed column 16 is slidably disposed within the fixing port. The moving mechanism is disposed within the first cavity 15 and is used to drive the fixed column 16 to move within the fixing port. The moving mechanism includes a positioning plate 17, a second threaded rod 18, and a synchronous rotation mechanism. The positioning plate 17 is slidably disposed within the first cavity 15 and is fixedly connected to the fixed column 16. The second threaded rod 18 is rotatably disposed within the first cavity 15 and passes through the positioning plate 17 via a threaded engagement. The synchronous rotation mechanism is disposed within the positioning frame 10 and is used to drive the two second threaded rods 18 to rotate synchronously. The synchronous rotation mechanism includes a second cavity, a second bevel gear 20, and a first rotation mechanism. The second cavity is located between the two first cavities 15, with the second cavity closer to the second threaded rod 18. A first bevel gear 19 is rotatably mounted on the side wall of the second cavity. A first connecting rod is fixed between the first bevel gear 19 and the adjacent second threaded rod 18. A second bevel gear 20 is rotatably mounted on the inner bottom wall of the second cavity and meshes with the first bevel gear 19. A first rotating mechanism is mounted on the lifting block 9 to drive the second bevel gear 20 to rotate. Specifically, the operation of the first rotating mechanism can drive the second bevel gear 20 to rotate. At the same time, the meshing of the second bevel gear 20 with the first bevel gear 19 can drive the first bevel gear 19 and the second threaded rod 18 to rotate. Simultaneously, the threaded engagement between the second threaded rod 18 and the positioning plate 17 can drive the positioning plate 17 and the fixed column 16 to move. Thus, the bottom of the positioning groove 12 can be clamped by the positioning column 11, and the positioning between the fixed column 16 and the bottom of the positioning groove 12 can be achieved by the friction between the fixed column 16 and the bottom of the positioning groove 12, thereby preventing the frame 1 from shaking during operation.

[0053] Reference Figure 3 and Figure 4The first rotating mechanism includes a first gear 21, a second gear 22, and a driving mechanism. The first gear 21 is rotatably mounted on the lifting block 9, and a second connecting rod is fixedly provided between the first gear 21 and the second bevel gear 20. The second gear 22 is rotatably mounted on the lifting block 9 and meshes with the first gear 21. The driving mechanism is mounted on the support frame 7 and is used to drive the second gear 22 to rotate. The driving mechanism includes a driving prism 23 and a second motor 24. The driving prism 23 is rotatably mounted on the support frame 7 and extends through the second gear 22 into the lifting block 9. The driving prism 23 is slidably connected to the second gear 22. The second motor 24 is mounted on the support frame 7, and the output end of the second motor 24 is connected to the driving mechanism. Prism 23 is fixedly connected, and a third cavity 25 is opened in the lifting block 9. A limit opening is opened in the inner bottom wall of the third cavity 25, and a limit block 26 is slidably arranged in the third cavity 25. The driving prism 23 passes through the limit opening and is rotatably connected with the limit block 26. The first motor 14 and the second motor 24 are forward and reverse motors. An anti-slip pad is fixedly installed on one end of the fixed column 16 near the frame 1. Specifically, the operation of the second motor 24 can drive the driving prism 23 to rotate. At the same time, the sliding engagement between the driving prism 23 and the second gear 22 drives the second gear 22 to rotate. It is also convenient to drive the first gear 21, the second connecting rod and the second bevel gear 20 to rotate through the meshing of the second gear 22 and the first gear 21.

[0054] In this embodiment, during use, the operator places the base 5 on one side of the electrostatic separator. The operator then controls the first motor 14, which rotates the first threaded rod 13. Simultaneously, the threaded engagement between the first threaded rod 13 and the lifting block 9 moves the lifting block 9, which in turn moves the positioning frame 10 and the positioning column 11. This allows the positioning column 11, in conjunction with the positioning groove 12, to adjust the angle of the frame 1, thereby adjusting the height of the discharge bin 4 on the frame 1 and aligning it with the feed inlet of the electrostatic separator. The operator then controls the second motor 24, which rotates the drive prism 23. The sliding engagement between the drive prism 23 and the second gear 22 rotates the second gear 22. Simultaneously, the second gear 22 interacts with the first gear 21... The meshing of the first gear 21, the second connecting rod, and the second bevel gear 20 can drive them to rotate. The meshing of the second bevel gear 20 with the first bevel gear 19 can drive the first bevel gear 19 and the second threaded rod 18 to rotate. At the same time, the threaded engagement of the second threaded rod 18 with the positioning plate 17 can drive the positioning plate 17 and the fixed column 16 to move. The positioning column 11 can clamp the bottom of the positioning groove 12. The friction between the fixed column 16 and the bottom of the positioning groove 12 can achieve positioning between the fixed column 16 and the bottom of the positioning groove 12, thereby preventing the frame 1 from shaking during operation. Afterwards, the operator can add material into the frame 1 through the feeding bin 3. Then, the plastic sheet is transported by the scraper conveyor body 2. Finally, the plastic sheet can be added into the electrostatic separator through the discharge bin 4.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
