Abstract
Description
Technical Field
[0001] This utility model relates to the field of PE plastic granule production technology, specifically to an automatic feeding device for a PE plastic granule production line. Background Technology
[0002] In the production of PE plastic granules, the material conveying process commonly uses screw conveyors or pneumatic conveyors. However, during screw conveying, when there is a mixture of PE plastic granules with significantly different diameters, the larger particles may gradually gather to one side under the push of the screw blades, forming a blockage point. Meanwhile, the smaller particles accumulate around them, exacerbating the blockage and ultimately hindering the continuous conveying of materials. This severely affects the continuity and stability of feeding. At the same time, when the material has moisture issues, direct feeding will also cause accumulation, reducing the efficiency of automatic feeding. Utility Model Content

Detailed Implementation
[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0018] Example: Figure 1-6 As shown, this utility model provides an automatic feeding device for a PE plastic granule production line, including a support plate 1. A storage box 10 is fixedly installed inside the support plate 1. The bottom end of the storage box 10 is conical. A discharge pipe 11 is fixedly installed at the bottom end of the storage box 10. A sealing mechanism is provided at the top of the discharge pipe 11. An inclined guide plate 12 is provided inside the discharge pipe 11. A screen 13 is fixedly installed in the middle of the guide plate 12. Two symmetrically distributed guide rods 14 are fixedly installed at the bottom end of the guide plate 12. A fixing block 15 is slidably sleeved on the outside of the guide rods 14. The fixing block 15 is fixedly connected to the inner wall of the discharge pipe 11. A moving plate 16 is fixedly installed at the bottom end of the guide rods 14. A rotating shaft 17 is rotatably installed through the bottom of the 1. An eccentric wheel 18 that works with the moving plate 16 is fixedly installed on the outside of the rotating shaft 17. The rotating shaft 17 is located at the eccentric part of the eccentric wheel 18. A first motor 19 that is fixedly connected to the rotating shaft 17 is fixedly installed on the outside of the discharge pipe 11. One end of the guide plate 12 passes through the discharge pipe 11. A discharge port 2 is opened on one side of the discharge pipe 11. A frame 21 is provided on the side of the discharge pipe 11 near the discharge port 2. A conveying pipe 22 is fixedly installed at the bottom of the frame 21. A spiral conveying roller 23 is rotatably installed in the middle of the conveying pipe 22. In use, the conveying pipe 22 and the spiral conveying roller 23 can be selected as inclined or horizontal according to the actual situation.
[0019] A fixing plate 3 is fixedly installed on one side of the storage box 10. A hot air blower 31 is fixedly installed on the top of the fixing plate 3. A fan pipe 32 is fixedly installed on the side of the hot air blower 31 near the storage box 10. The fan pipe 32 passes through the storage box 10. A square pipe 33 is fixedly installed on the side of the fan pipe 32 away from the hot air blower 31. The square pipe 33 is fixedly connected to the storage box 10. Several evenly distributed inclined air outlet pipes 34 are fixedly installed on the inner wall of the square pipe 33.
[0020] A stirring shaft 4 is rotatably driven through the middle of the storage tank 10. Several sets of evenly distributed stirring blades 41 are fixedly installed on the outside of the stirring shaft 4. A second motor 42, which is fixedly connected to the stirring shaft 4, is fixedly installed at the top of the storage tank 10. By setting the stirring shaft 4, when the second motor 42 is started, it drives the stirring shaft 4 and the stirring blades 41 to rotate, thereby stirring the PE plastic granules in the storage tank 10, so that the PE plastic granules dry more evenly. At the same time, it helps to discharge the PE plastic granules in the storage tank 10, avoiding the situation of discharging too much material at once.
[0021] A spiral conveyor blade 5 is fixedly installed at the bottom of the stirring shaft 4. By setting the spiral conveyor blade 5, the PE plastic particles at the bottom of the storage box 10 are conveyed upward, so that the PE plastic particles are dried more evenly and the PE plastic particles at the bottom of the storage box 10 are not dried.
[0022] The sealing mechanism includes an L-shaped block 6. An electric push rod 61 is fixedly installed on the side of the discharge pipe 11 near the discharge port 2. The electric push rod 61 is fixedly connected to the L-shaped block 6. A baffle 62 is fixedly installed on the side of the L-shaped block 6 near the discharge pipe 11. The baffle 62 is slidably connected to the discharge pipe 11. By setting the electric push rod 61, the back-and-forth movement of the electric push rod 61 is controlled, which drives the baffle 62 to move back and forth in the discharge pipe 11. This allows the dried PE plastic granules to be intermittently discharged from the outlet of the storage box 10 and fall onto the screen 13, thereby improving the screening of PE plastic granules of different sizes and avoiding too much material being discharged at once, which would affect the screening of PE plastic granules.
[0023] A spring 7 is fixedly installed between each fixed block 15 and the movable plate 16. The spring 7 is located outside the guide rod 14. By setting the spring 7, when the movable plate 16 moves up and down, the spring 7 will also contract, thereby increasing the shaking frequency of the guide plate 12 and the screen 13, and further improving the screening of PE plastic particles of different sizes.
[0024] An L-shaped plate 8 is fixedly installed at the top of the conveying pipe 22. The L-shaped plate 8 is fixedly connected to the storage box 10. By setting the L-shaped plate 8, the conveying pipe 22 is supported, so that the conveying pipe 22 can work normally.
[0025] Side plates 9 are fixedly installed on both sides of the guide plate 12. By setting the side plates 9, the PE plastic granules screened by the screen 13 are prevented from slipping off the edge of the guide plate 12, thus affecting the feeding of PE plastic granules.
[0026] Working principle: The drive motors of the first motor 19, the second motor 42, the electric push rod 61, and the screw conveyor roller 23 are all controlled by an external controller. The end of the conveying pipe 22 away from the discharge pipe 11 is connected to the equipment that needs to be fed. In actual use, when PE plastic granules need to be fed, a collection box is placed below the discharge pipe 11. Then, the reciprocating movement of the sealing mechanism is controlled to start the motor on the screw conveyor roller 23, the first motor 19. The start of the first motor 19 drives the rotating shaft 17 to rotate. The eccentric wheel 18 on the rotating shaft 17 rotates accordingly. Since the eccentric wheel 18 cooperates with the moving plate 16 and the rotating shaft 17 is located at the eccentric part of the eccentric wheel 18, the rotation of the eccentric wheel 18 will push the moving plate 16 and the guide rod 14 to move up and down in the fixed block 15. The up and down reciprocating movement of the guide rod 14 drives the guide plate 12 and the screen 13 to move up and down, thereby screening the PE plastic granules of different sizes.
[0027] Qualified PE plastic granules slide down the screen 13 along the guide plate 12 to the discharge port 2 of the discharge pipe 11, and then pass through the frame 21 into the conveying pipe 22. They are then conveyed by the screw conveyor roller 23 to realize the automatic feeding of PE plastic granules. Small granules are screened by the screen 13 and directly exit from the discharge port of the discharge pipe 11, falling into the collection box for further processing.
[0028] Before feeding, if the PE plastic granules are damp, start the hot air blower 31. The hot air generated enters the square pipe 33 through the blower pipe 32, and then is evenly blown into the storage box 10 through the inclined air outlet pipe 34 on the inner wall of the square pipe 33, so as to dry the PE plastic granules and improve the flowability of the PE plastic granules during conveying. After drying, feed the material and turn off the hot air blower 31.
[0029] At the same time, the second motor 42 needs to be reversed to drive the stirring shaft 4, stirring blade 41, and spiral conveyor blade 5 to reverse and feed the dried PE plastic granules.
[0030] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
