Description

Technical Field

[0001] This utility model relates to the field of plastic processing technology, specifically to a plastic granule drying structure. Background Technology

[0002] In the plastic processing process, drying equipment is used to remove moisture or volatiles from plastic granules to avoid processing defects (such as bubbles, silver streaks, and reduced strength) caused by moisture.

[0003] For example, a Chinese patent announcement number CN221937265U describes an airflow drying device for processing plastic particles, which includes a drying chamber. A hot air blower is fixedly mounted on the side wall of the drying chamber. The air inlet of the hot air blower is connected to the interior of the drying chamber. The interior of the drying chamber is provided with two rotating shafts. Two actuating plates are fixedly connected to each of the two rotating shafts. Several through holes are opened on both sides of the actuating plates. The drying chamber is provided with a drive assembly for driving the two rotating shafts to rotate.

[0004] The drying equipment in the aforementioned patent can only reduce the temperature difference during use. However, existing drying equipment, due to the single-pass transmission of materials, results in insufficient drying of the moisture in the plastic granules. Therefore, an improved device is needed to address this issue. Utility Model Content

Detailed Implementation

[0019] 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.

[0020] Please see Figure 1-4 An embodiment of this utility model provides a plastic granule drying structure, including a transfer device 2. A conveying device 1 is fixedly installed at the bottom front end of the transfer device 2, and a guiding device 3 is fixedly installed at the rear bottom end of the transfer device 2. The conveying device 1 includes a spiral blade 4, a conveying cylinder 5, a feeding cavity 6, and a drive motor 7. The drive motor 7 is fixedly installed at the bottom end of the conveying cylinder 5, the spiral blade 4 is fixedly installed at the top end of the drive motor 7, and the feeding cavity 6 is fixedly installed at the top end of the outer ring of the conveying cylinder 5.

[0021] The transfer device 2 includes an accumulation cavity 8, a square hole 9, a flow guiding cavity 10, a delivery pipe 11, a mating base 12, and a flow guiding side plate 13. The mating base 12 is fixedly installed inside the bottom of the accumulation cavity 8. The flow guiding side plate 13 is symmetrically fixedly installed on the top side of the mating base 12. The square hole 9 is opened at the bottom rear end of the accumulation cavity 8. The flow guiding cavity 10 is symmetrically fixedly installed at the bottom rear end of the accumulation cavity 8. The delivery pipe 11 is fixedly installed at the bottom end of the flow guiding cavity 10. A vertical groove is opened at the bottom rear end of the mating base 12, which facilitates the fitting of the sealing plate 17 with the mating base 12.

[0022] The guiding device 3 includes a connecting base rod 14, a hydraulic cylinder 15, a discharge plate 16, and a sealing plate 17. The connecting base rod 14 is fixedly installed at the rear end of the hydraulic cylinder 15, the discharge plate 16 is fixedly installed between the two connecting base rods 14, and the sealing plate 17 is fixedly installed at the front end of the discharge plate 16. The side surface of the discharge plate 16 away from the sealing plate 17 is inclined at 45°, which can increase the flow speed of the plastic particles.

[0023] Hydraulic cylinders 15 are symmetrically fixedly installed at the rear end of the accumulation cavity 8, the front end of the conveying pipe 11 is connected to the inside of the feed cavity 6, and the conveying cylinder 5 is fixedly installed at the center of the mating base 12, so that the spiral blades 4 can convey plastic particles to the inside of the accumulation cavity 8.

[0024] The feed chamber 6 is hollow inside and is interconnected with the inside of the conveying cylinder 5, which facilitates the return of plastic particles to the inside of the conveying cylinder 5.

[0025] The sealing plate 17 has the same dimensions as the inner wall of the square hole 9, which makes it easy for the sealing plate 17 to seal the inside of the square hole 9.

[0026] Working Principle: During use, the top cover of the accumulation chamber 8 can be opened, and plastic granules can be conveyed into the accumulation chamber 8. The accumulation chamber 8 is interconnected with the guide chamber 10, allowing the plastic granules to be conveyed from the guide chamber 10 and the conveying pipe 11 to the feed chamber 6. At this time, the drive motor 7 can be turned on, driving the spiral blades 4 to rotate inside the conveying cylinder 5. The spiral blades 4 then convey the plastic granules inside the feed chamber 6 upwards. The conveying cylinder 5, through the base 12, is interconnected with the accumulation chamber 8, allowing the plastic granules to be conveyed back into the accumulation chamber 8. Simultaneously, connecting pipes are symmetrically fixed to the top of the accumulation chamber 8 and connected to an external hot air blower, allowing hot air to enter the accumulation chamber 8. The interconnection between the accumulation chamber 8, guide chamber 10, conveying pipe 11, conveying cylinder 5, and feed chamber 6 allows hot air to flow, improving the drying effect of the plastic granules. Furthermore, the spiral blades 4 can repeatedly convey the plastic granules. The flow of particles prevents clumping or incomplete drying of plastic particles. Then, when the plastic particles are dried to a suitable state, the hydraulic cylinder 15 is activated, moving the connecting rod 14 closer to the accumulation cavity 8 until the sealing plate 17 is in contact with the rear end of the mating base 12. This allows the discharge plate 16 to be positioned below the guide side plate 13. At this point, the plastic particles conveyed by the spiral blades 4 flow to the top of the discharge plate 16, discharging the dried particles. After the plastic particles are discharged, the hydraulic cylinder 15 is activated again, moving the connecting rod 14 away from the accumulation cavity 8 until the sealing plate 17 enters the square hole 9, sealing the square hole 9 and preventing the plastic particles from flowing out of the square hole 9 when the spiral blades 4 convey them again. In use, the guide side plate 13 is aligned with the discharge plate 16, allowing the plastic particles to slide precisely onto the discharge plate 16, improving the smoothness of the discharge.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
