Description

Technical Field

[0001] This utility model relates to the field of material suction machine technology, and more specifically, to a plastic rice suction machine. Background Technology

[0002] Plastic pellet feeders are automatic conveying devices used in plastic processing to transport plastic pellets (commonly known as "plastic pellets"). They can replace manual handling, delivering raw materials from the hopper to injection molding machines, extruders, and other equipment, saving time and labor. With the development of the plastics industry, feeders are becoming increasingly popular. Modern feeders operate on the principle of negative pressure, using a vacuum pump to generate suction, drawing plastic pellets from the hopper through pipes into the storage bin. The entire process is enclosed and dust-free, resulting in a cleaner workshop environment. They can also precisely control the feeding amount and work with the injection molding machine to automatically start and stop, preventing raw material accumulation or material shortages. Many feeders also have an automatic cleaning function, using high-pressure air to blow away residues in the pipes during material changes, reducing cross-contamination.

[0003] When screening plastic granules, the filter screen of traditional suction feeders is prone to clogging due to the accumulation of granules (especially clumps), which affects screening efficiency and feeding speed, and may even require frequent shutdowns for cleaning. Traditional filter screens are mostly fixed with bolts, which require tools for disassembly and assembly, and are difficult to operate in an environment with residual plastic granules, which is time-consuming, labor-intensive, and increases maintenance costs.

[0029] Please see Figures 1-5A plastic rice suction feeder includes a main body 1, a feeding box 2 on the main body 1, a feeding pipe 3 and a suction pump 4 on the feeding box 2, a partition 5 on the feeding box 2, a rotating shaft 6 on the partition 5, a guide plate 7 on the rotating shaft 6, filter screens 8 on both sides of the partition 5, and an installation device and an installation plate 9 on the outer side of the filter screens 8. The installation device includes an installation sleeve 10, which is fixedly mounted on the installation plate 9. An installation rod is provided on the feeding box 2. 11. The mounting sleeve 10 is provided with a snap-fit ​​groove 12, and a snap-fit ​​rod 13 is rotatably provided on the snap-fit ​​groove 12. The mounting rod 11 is provided with a snap-fit ​​ring groove 15 that cooperates with the snap-fit ​​rod 13. The rotating shaft 6 is provided with a worm gear 24, and the feed box 2 is rotatably provided with a worm 25. The feed box 2 is provided with a support plate 26, a support spring 27 is provided on the support plate 26, an elastic ball 28 is provided on the support spring 27, an electromagnet 29 is provided on the support plate 26, and a permanent magnet 30 is provided on the elastic ball 28.

[0030] In this embodiment, during use, the connection of the suction pump 4 and the feed pipe 3 of the main body 1 of the suction machine adopts existing technology. The negative pressure generated by the connection with the feed pipe 3 suctions the plastic granules, preventing them from entering the suction pump 4. The plastic granules then enter the feed box 2 and slide onto the filter screen 8 on one side of the partition 5 under the guidance of the guide plate 7. To prevent plastic accumulation, the electromagnet 29 is energized. The energized electromagnet 29 generates magnetism, attracting the permanent magnet 30 and the elastic ball 28 to move upwards and compress the support spring 27. Subsequently, after the electromagnet 29 is de-energized, the elastic ball 28 moves up and down repeatedly under the elastic force of the support spring 27, striking the surface. The vibration of the filter screen 8 and plastic particles, and the elastic ball 28 is controlled by the energization of the electromagnet 29. This allows large particles and clumps of particles to be filtered through the filter screen 8, improving the quality of subsequent production. This application only improves the screening measures for large particles and clumps of particles; the screening methods for other impurities all adopt existing technologies. When the filter screen 8 needs to be cleaned, the worm gear 25 is rotated, which drives the worm wheel 24 and the rotating shaft 6 to rotate. The rotating shaft 6 drives the guide plate 7 to rotate, which facilitates the guidance of plastic particles to the filter screen 8 on the other side. At the same time, the filter screen 8 that needs to be cleaned can be disassembled and cleaned, thereby reducing downtime maintenance time and improving the continuity of production.

[0031] Please see Figures 4-5 As one embodiment of the installation device: the installation sleeve 10 is provided with a reset ring 16, the reset ring 16 is provided with a reset rack 17 in the snap-fit ​​groove 12, the snap-fit ​​rod 13 is provided with a reset gear 18 that cooperates with the reset rack 17, the reset ring 16 is provided with a reset plate 19, a reset spring 20 is provided between the reset plate 19 and the installation sleeve 10, the installation sleeve 10 is provided with a pressure plate 21, a pressure spring 22 is provided between the pressure plate 21 and the installation sleeve 10, and the installation rod 11 is provided with an inclined surface 23 that cooperates with the snap-fit ​​rod 13.

[0032] More specifically, when installing the filter screen 8, align the mounting sleeve 10 on the mounting plate 9 with the mounting rod 11, insert the mounting rod 11 into the mounting sleeve 10, and press the inclined surface 23 of the mounting rod 11 against the snap-fit ​​rod 13, causing the snap-fit ​​rod 13 to extend into the snap-fit ​​groove 12. This causes the reset rack 17 and reset ring 16 to move towards the reset spring 20, compressing the reset spring 20. Simultaneously, the mounting rod 11 compresses the clamping plate 21 and the clamping spring 22. When the snap-fit ​​rod 13 encounters the snap-fit ​​ring groove 15, under the elastic force of the reset spring 20, the snap-fit ​​rod 13 extends into the snap-fit ​​ring groove 15 through the cooperation of the reset rack 17 and the reset gear 18, cooperating with the clamping plate 21. The squeezing action of the clamping spring 22 and the mounting plate 9 makes the locking rod 13 and the locking ring groove 15 lock stably, which facilitates the installation of the mounting plate 9 and the filter screen 8. At the same time, when removing the mounting plate 9 and the filter screen 8, the reset ring 16 is moved, and the reset plate 19 drives the reset plate 19 to squeeze the reset spring 20. At the same time, the reset ring 16 drives the reset rack 17 to move, and the reset rack 17 drives the reset gear 18 to rotate, which in turn drives the locking rod 13 to extend into the locking groove 12, so that the mounting rod 11 can be removed. Then the reset ring 16 is reset under the action of the reset spring 20, which improves the convenience of installing and removing the mounting plate 9 and the filter screen 8 and makes it easier to clean the filter screen 8.

[0033] In summary, during the use or operation of the overall equipment: When in use, the connection between the suction pump 4 and the feed pipe 3 of the main body 1 of the suction machine adopts existing technology. The negative pressure generated by the connection with the feed pipe 3 sucks up the plastic granules, preventing them from entering the suction pump 4. The plastic granules then enter the feed box 2 and slide onto the filter screen 8 on one side of the partition 5 under the guidance of the guide plate 7. To prevent plastic accumulation, the electromagnet 29 is energized. The energized electromagnet 29 generates magnetism, attracting the permanent magnet 30 and the elastic ball 28 to move upwards and compress the support spring 27. Subsequently, after the electromagnet 29 is de-energized, the elastic ball 28 moves up and down repeatedly under the elastic force of the support spring 27. The vibration of the elastic ball 28, controlled by the energization of the electromagnet 29, is achieved by striking the filter screen 8 and the plastic particles. This allows large particles and clumps of particles to be filtered through the filter screen 8, improving the quality of subsequent production. This application only improves the screening measures for large particles and clumps of particles; the screening methods for other impurities are based on existing technologies. When the filter screen 8 needs to be cleaned, the worm gear 25 is rotated, which drives the worm wheel 24 and the rotating shaft 6 to rotate. The rotating shaft 6 then drives the guide plate 7 to rotate, facilitating the guidance of the plastic particles onto the filter screen 8 on the other side. At the same time, the filter screen 8 that needs to be cleaned can be disassembled and cleaned, thereby reducing downtime for maintenance and improving the continuity of production.

[0034] When installing the filter screen 8, align the mounting sleeve 10 on the mounting plate 9 with the mounting rod 11, and insert the mounting rod 11 into the mounting sleeve 10. The inclined surface 23 of the mounting rod 11 presses against the snap-fit ​​rod 13, causing the snap-fit ​​rod 13 to extend into the snap-fit ​​groove 12. This causes the reset rack 17 and reset ring 16 to move towards the reset spring 20, compressing the reset spring 20. Simultaneously, the mounting rod 11 compresses the clamping plate 21 and the clamping spring 22. When the snap-fit ​​rod 13 encounters the snap-fit ​​ring groove 15, under the elastic force of the reset spring 20, the snap-fit ​​rod 13 extends into the snap-fit ​​ring groove 15 through the cooperation of the reset rack 17 and the reset gear 18, cooperating with the clamping plate 21 and the clamping spring 22. The compression action of the spring 22 ensures that the locking rod 13 is stably engaged with the locking ring groove 15, thus facilitating the installation of the mounting plate 9 and the filter screen 8. Simultaneously, when disassembling the mounting plate 9 and the filter screen 8, the reset ring 16 moves, causing the reset plate 19 to compress the reset spring 20. At the same time, the reset ring 16 moves the reset rack 17, which in turn rotates the reset gear 18, causing the locking rod 13 to extend into the locking groove 12. This allows the mounting rod 11 to be removed. Subsequently, the reset ring 16 resets under the action of the reset spring 20, improving the ease of installation and disassembly of the mounting plate 9 and the filter screen 8, and facilitating the cleaning of the filter screen 8.
