Abstract
Description
Technical Field
[0001] This utility model relates to the field of plastic strip drying technology, specifically a plastic strip suction and blowing integrated air dryer system. Background Technology
[0002] The production of plastic strips is completed by melting them at a certain temperature and then extruding them through an extruder. After extrusion, the plastic strips are at a high temperature and must be cooled before they can be pelletized into finished products. Currently, the commonly used cooling method in production is water cooling. However, this method requires the strips to be dehydrated. If the moisture on the strips is not completely removed, the residual moisture will enter the pelletizer, causing the equipment to rust and contaminating the color of the product. High moisture content will also lead to compromised product quality, increase costs and waste resources during processing and molding. Therefore, a plastic strip drying machine is needed to dry the plastic strips.
[0003] Currently, most plastic strip drying machines on the market use a single-pass drying process with a blower, which requires the plastic strip to maintain a low forward speed to achieve a good drying effect. This drying method is increasingly unable to keep up with the ever-faster production pace and has low efficiency.
[0004] Therefore, we propose a plastic strip suction and blowing integrated air drying machine system to solve the problems mentioned above. Utility Model Content

Threaded columns are symmetrically connected to both sides of the suction box. The connecting plates are provided with sleeve holes that fit into the threaded columns, and an adjusting nut is threaded onto the threaded columns.
