Description

TECHNICAL FIELD

[0001] The utility model relates to the field of sheet production, especially a melt pressure stabilizing device for extruded sheet. BACKGROUND

[0002] The melt pressure stabilizing device for extruded sheet usually refers to a melt pump, which is a positive displacement conveying device and is widely used in the sheet extrusion production line of polymer materials such as plastics, resins and rubber. The melt pump can pressurize the high-temperature melt from the extruder and stably send it into the extruder head, thereby eliminating the influence of the extruder screw pulsation on the pressure and ensuring the stability of the pressure in the entire extrusion process.

[0003] After searching Chinese patents, the patent with publication number CN215058127U is a melt pump with long-term stable and reliable operation. It includes a pump housing, a pump cover, a driving gear shaft, a driven gear shaft, and a sliding shaft sleeve. The driving gear shaft and the driven gear shaft have corresponding sliding shaft sleeves with a backflow lubrication channel between them. The backflow lubrication channel includes a backflow inlet section, a sliding shaft sleeve lubrication section, a cover plate convergence section, and a backflow outlet section. The backflow lubrication channel returns from the discharge area to the feed area. The driving gear shaft passes through one of the pump covers and is connected to the power mechanism. A triple sealing device is provided between the driving gear shaft and the pump cover. It has good lubricity and sealing performance, ensuring the stability and reliability of the melt pump in long-term operation. Its structure is simple, reasonable in design, easy to process, practical, and has good lubrication and sealing effect.

[0004] The existing melt pressure stabilizing device does not have a filtering function. Generally, the melt pump directly transports the melt. Since there are impurities in the melt, these impurities not only affect the quality of the melt, but also increase the wear rate of the parts in the melt pump, affecting the service life of the melt pump. It is also not convenient to connect with the connecting pipe. Generally, the melt pump is connected with the connecting pipe through flanges and bolts. This connection method requires the use of tools for assembly and disassembly, which is cumbersome and increases the workload, reducing work efficiency. To solve the above problems, we propose a melt pressure stabilizing device for extruded sheet. Utility model content
