Description

Technical Field

[0001] The present invention relates to the technical field of sandwich bread production, and in particular to a sandwich bread pressing device. Background Art

[0002] Sandwich bread has jam, cream and other sauces added inside it, and is widely loved for its unique taste. In actual production, there are two main types of sandwich bread, one is sandwich toast bread and the other is sandwich pocket bread. Sandwich pocket bread is made by pressing sandwich toast bread, removing the surrounding crust, and pressing the middle part as a whole into a pocket structure. Current sandwich bread pressing devices mostly use a top-down pressing method for pressing, which is not convenient for placing the bread to be pressed, discharging the finished product, and discharging the scraps, resulting in unsatisfactory production efficiency. At the same time, it is impossible to switch between sandwich toast bread and sandwich pocket bread. In actual production, the two types of bread require separate production lines, which greatly increases equipment costs. Summary of the Invention

The upper rotating shaft 10 and the lower rotating shaft 8 rotate continuously, and the upper mold 11 and the lower mold 9 rotate toward the discharge end of the pressing guide assembly 5 at the same time. The scraps cut off from the surface of the lower mold 9 are introduced into the surface of the waste belt conveyor 3 through the pressing guide assembly 5 to convey the waste; the lower mold 9 continues to rotate with the lower rotating shaft 8, so that the pocket bread inside it that has been pressed falls on the surface of the finished product belt conveyor 2 and is transported to the packaging device for packaging. The sandwich pocket bread is pressed by rotating pressing. During the rotation, the placement of the bread to be pressed, the discharge of the finished product and the discharge of the scraps are realized without affecting each other, which helps to improve production efficiency; the pressing frame 4 is driven to move by adjusting the driving member 7 to realize the position adjustment of the pressing assembly and the transition belt conveyor 6, so that the pressing assembly or the transition belt conveyor 6 can be selected to correspond to the production line to realize the production switching of sandwich toast bread and sandwich pocket bread, which helps to reduce equipment costs.
