Description

Technical Field

[0001] The present application relates to the field of packaging technology, and in particular to a sloped paper feeding device and a paper wrapping machine. Background Art

[0002] A paper wrapping machine is a fully automatic packaging machine that groups and packages containers such as glass bottles, plastic bottles, and cans using a single sheet of cardboard (also known as paperboard). The machine's operating principle generally involves sorting and grouping the materials to be packaged, conveying the cardboard sheets one by one, placing the sorted and grouped materials on the corresponding cardboard sheets, and then folding and pressing the loaded cardboard sheets into cartons.

[0003] In the prior art, cardboard is typically fed in from the side of the material. Because the material's conveying direction is inconsistent with the cardboard's conveying direction, the material needs to be stopped when combining the material and cardboard (loading the material onto the corresponding cardboard). This requires that the material be conveyed and then conveyed again after the two are combined, resulting in low processing efficiency. To address this issue, a related art has proposed an inclined paper feeding device. This device is used to feed the cardboard from below the material to the bottom of the material along the material's conveying direction. This eliminates the need to stop the material's conveying when combining the material and cardboard, thereby improving processing efficiency.

[0004] However, when conveying cardboard, the traditional inclined paper feeding device may cause the cardboard to move left and right due to vibration or collision, resulting in a misalignment between the cardboard and the material to be carried. This may cause the cardboard to get stuck in subsequent processing steps and easily cause the final carton containing the material to be uneven and unsightly. Utility Model Content
