Description

Technical Field

[0001] This utility model relates to the field of feeding equipment technology, specifically a quantitative feeding device for plastic granules. Background Technology

[0002] Plastics are polymer compounds formed by polymerization of monomers through addition or condensation reactions. Plastic granules are commonly used as raw materials for plastic products. After manufacturing, they need to be loaded into packaging bags by a feeding device for convenient transportation. In current technology, most plastic granule feeding devices use an auger in conjunction with a conveyor pipe for feeding, and the discharge port of the conveyor pipe is manually opened and closed. This results in inconsistent amounts of plastic granules being loaded into the packaging bag each time, making it impossible to achieve accurate quantitative feeding.

[0003] In response, Chinese utility model patent CN220281741U discloses a quantitative feeding device for plastic granules, including a feeding box with grooves at both ends. An adjusting block is slidably connected inside the grooves, and a support plate is fixedly connected to the outside of the feeding box. With this utility model, plastic granules enter through the opening at the upper end of the adjusting block and between two partitions at the corresponding opening. A motor then drives a driving rod to rotate the adjusting rod and adjusting cylinder 90 degrees. The partition at the upper opening moves to engage with the inner side of the adjusting block to store the incoming plastic granules. The stored granules then fall from the lower opening and are finally fed through the feeding pipe. The cooperation between the partitions and the inner wall of the adjusting block ensures that the amount fed each time is approximately the same, thus achieving a good quantitative feeding effect.

[0004] Sometimes it is necessary to adjust the amount of material fed according to the processing needs. To address this issue, we propose a quantitative feeding device for plastic granules. Utility Model Content
