Description

Technical Field

[0001] The utility model relates to the technical field of EPP machines, in particular to a mobile EPP machine. Background Art

[0002] EPP is the abbreviation of Expanded polypropylene, which is a new type of foam plastic. EPP has light specific gravity, good elasticity, shock and compression resistance, high deformation recovery rate, good absorption performance, oil resistance, acid resistance, alkali resistance, resistance to various chemical solvents, non-absorbent, insulation, heat resistance (-40 ~ 130 ℃), non-toxic and odorless, 100% recyclable with almost no performance reduction, and is a truly environmentally friendly foam plastic.

[0003] The EPP molding process requires the use of a molding machine. After searching, a Chinese patent with publication number CN106273199A discloses an EPP molding machine, including a frame, a die, a punch and a die pressing mechanism. The die is fixedly mounted on the frame, the punch is laterally opposite to the die, and the die pressing mechanism drives the punch to move toward the die. A countersunk hole is opened at the bottom of the groove of the die, the large hole of the countersunk hole is close to the bottom of the groove of the die, and the small hole of the countersunk hole is close to the back of the die. It also includes a unloading mechanism, which includes a push plate, a push rod and a transmission member. The push plate is located in the large hole of the countersunk hole, one end of the push rod is connected to the push plate and the other end passes through the small hole of the countersunk hole and extends to the outside of the die. The push rod is slidably matched with the small hole of the countersunk hole, and the transmission member can push the push rod to enable the push plate to push the foam board in the die out of the die.

[0004] This patent is the same as the traditional molding machine, which is a fixed structure and is placed on the ground as a whole. Since the molding machine is large in size and heavy in weight, it is not convenient to move the molding machine. Therefore, we propose a mobile EPP machine to solve the above problem.
