Description

One-pump multi-station hydraulic device applied to fully automatic energy-saving pulp packaging equipment

technical field

The utility model relates to the field of pulp forming equipment, more specifically a one-pump multi-station hydraulic device applied to automatic energy-saving pulp packaging equipment.

Background technique

Pulp molded catering utensils and supplies have been widely used in the market at present, and the level of automation in the production process of pulp molded tableware is getting higher and higher. The entire production process includes mold blank forming, drying and setting, automatic collection, etc. Among them, in the drying and setting process, the forming upper mold and the forming lower mold are generally pressed together, and then heated and dried, and finally the paper-plastic tableware is formed at one time. In the process of pressing the upper and lower molds, Most of the production equipment uses hydraulic lifting equipment to push the lower mold to the direction of the upper mold. The traditional hydraulic lifting equipment is composed of a single hydraulic device. Since the forming lower mold is not a single mold body, but multiple side by side It is composed of a combination of settings, so the area will be relatively large. When the single hydraulic device is pushed, the upward running process of the lower mold not only needs to increase the hydraulic output power, but also often occurs due to the excessive area of the lower mold during the upward running process. Insufficient stability and uneven force will easily cause the lower mold to shift or shake during the rising process, so that the upper and lower molds cannot be well matched and pressed, which will affect the molding process of paper-plastic tableware.
