AI Technical Summary

Technical Problem

In the current sponge foaming process, because the operator cannot adjust the downward pressure of the pressing device in real time, the shape and density of the top of the sponge are inconsistent, resulting in reduced sponge utilization and wasted manpower.

Method used

The frame structure and the top structure are supported by a counterweight component and a pressure regulating component. By automatically adjusting the tension of the pressure regulating component, the top structure can be raised and lowered, and the downward pressure can be adjusted in real time to maintain the flatness and density of the top of the sponge.

Benefits of technology

It achieves automatic flattening of the top of the sponge, improves sponge utilization, saves labor costs, and can maintain the sponge height uniformity when the foaming environment changes.

Abstract

This invention relates to the field of sponge foaming, and provides a continuous foaming capping device for sponge with automatic downward pressure adjustment. The device includes a frame structure, a capping structure disposed at the bottom of the frame structure, and a lifting structure. The frame structure drives the capping structure to move up and down. The counterweight component and pressure-adjusting component of the lifting structure are both connected to the capping structure and can jointly lift the capping structure and the frame structure. The pressure-adjusting component automatically adjusts its pulling force on the capping structure. The total pulling force of the counterweight component and the pressure-adjusting component is less than, greater than, or equal to, the total weight of the frame structure and the capping structure, enabling the capping structure to move up and down automatically. This capping device, by automatically adjusting the pulling force of the pressure-adjusting component, allows the capping structure to move up and down automatically, thereby adjusting the downward pressure of the capping structure on the top of the sponge in real time. This achieves automatic compression of the top protrusion of the sponge by the capping structure, saving labor costs while maintaining the flatness, density, and height of the sponge top, thus improving sponge utilization.
