Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of plastic particle melting, particularly to a plastic particle melting and plasticizing device. BACKGROUND

[0002] In the plastic processing industry, the melting and plasticizing of plastic particles is a key link in the production process, directly affecting the quality and production efficiency of the final product. Usually, plastic particles enter the screw extruder through the feed hopper and are melted and plasticized under the action of high temperature and shear force, finally forming the required plastic products. However, in the actual production process, plastic particles often physically adhere and form clumps due to changes in environmental humidity and temperature or long-term pressure during storage or transportation. This problem is more prominent in plastic materials with strong hygroscopicity, such as PET and PA.

[0003] These clumped plastic particles, due to their large block volume and poor flowability, are prone to accumulate at the feed inlet when entering the feed hopper, causing poor feeding or even complete blockage. This not only leads to production interruption and increases the frequency of manual cleaning, but also may affect the melting effect of the screw extruder due to uneven feeding, resulting in incomplete plasticization, product defects such as bubbles or uneven strength. In addition, frequent blockage problems can also accelerate equipment wear and tear, shorten the service life of key components, and increase maintenance costs. Therefore, the plastic particle melting and plasticizing device is proposed to solve the above problems. SUMMARY

[0020] Specifically, the connecting ear 8 on the elastic connector 3 has an installation through hole 9, the guide rod 10 is slidably installed in the installation through hole 9, the upper anti-detachment baffle 11 is located above the upper connecting ear 8, the lower anti-detachment baffle 11 is located below the lower connecting ear 8, the upper rigid connecting frame 7 is fixedly connected to the container 18, the lower rigid connecting frame 7 is fixedly connected to the feed hopper 2, the vibration spring 17 is fixedly connected to the connecting ear 8, the filter screen 13 on the vibration assembly 4 is close to the lower end of the container 18, the two connecting plates 16 on the outer side of the striking assembly 5 are fixedly connected to the inner wall of the container 18, the mesh diameter of the filter screen 13 is larger than the diameter of the plastic particles, thereby ensuring that the unagglomerated plastic particles can smoothly pass through the mesh of the filter screen 13; when the vibration motor 14 works, all components of the entire device work together, the specific working state is as follows: after the vibration motor 14 starts, it drives the container 18 to generate high-frequency vibration, so that the internal plastic The particles disperse rapidly on the filter screen 13, which is located near the lower end of the container 18. During vibration, qualified plastic particles fall through the mesh, while agglomerated or excessively large particles are intercepted above the filter screen 13. Under the vibration of the vibration motor 14, the shaking rod 15 generates elastic swing through the vibration springs 17 on both sides, continuously impacting the agglomerated plastic particles, breaking them into smaller particles, and thus allowing them to pass smoothly through the filter screen 13. The vibration of the vibration motor 14 is transmitted through the container 18 to the upper rigid connecting frame 7 of the elastic connector 3. The corrugated connecting pipe 6 can extend and retract slightly to adapt to the vibration, while the guide rod 10 slides in the mounting through hole 9 of the connecting ear 8. The support spring 12 buffers the vibration energy, preventing the vibration from being directly transmitted to the feed hopper 2 and the screw extruder 1, ensuring stable equipment operation. The anti-detachment baffle 11 limits the sliding range of the guide rod 10, prevents the support spring 12 from being over-compressed or stretched, and ensures the durability of the elastic connector 3.

[0021] Ultimately, through the synergistic action of the vibration component 4 and the impact component 5, agglomerated plastic particles can be effectively broken up, preventing them from clogging during the feeding process, ensuring smooth feeding, reducing the probability of clogging, reducing equipment wear, lowering maintenance costs, and improving production efficiency. The filter screen 13 can screen out agglomerated particles, ensuring that the plastic particles entering the screw extruder 1 are distinct, thereby improving the uniformity of melt plasticization and the quality of the final product. The elastic connector 3 adopts a combination design of corrugated connecting pipe 6, guide rod 10, and support spring 12, which can both buffer the vibration transmitted by the vibration component 4 and maintain the stability of the structure, effectively reducing resonance during equipment operation and extending the service life of the screw extruder 1 and the feed hopper 2.
