AI Technical Summary
In the existing technology, it is difficult to produce packaging paper trays of cylindrical non-woven fabric rolls quickly and efficiently. Manual folding is inefficient and costly, which makes it impossible to meet order demand in a timely manner. In addition, the manual folding effect is poor and it is impossible to keep stock for a long time.
Design a pre-folding device for packaging paper trays, comprising a support component, a pressing component, a limiting plate, and a limiting post. The pressing component is driven by a drive motor to cooperate with the support component, thereby achieving rapid and efficient folding of the packaging paper tray mother plate to form a packaging paper tray with an L-shaped longitudinal section.
It enables rapid and efficient production of formed packaging paper trays, reduces production costs, solves the problem of low efficiency in manual folding, meets order demands, avoids the need for long-term inventory, and improves the yield rate.

Abstract
Claims
1. A carton disc pre-flanging apparatus characterised in that: The device includes a mounting frame located between the traction end and the feeding end, and a pre-folding assembly for pre-folding the packaging paper tray motherboard. The pre-folding assembly is mounted on the mounting frame and includes a support member (1) fixedly connected to the mounting frame, a pressing member (2) located above the support member (1), and limiting plates (4) and limiting posts (5) located on both sides of the support member (1). The pressing member (2) is connected to the mounting frame and is driven by a drive motor to move up and down relative to the support member (1). The two outer sides of the pressing member (2) extend obliquely downward and form an angle. The lower parts of the two outer sides of the pressing member (2) are connected by an arc-shaped transition surface (3) to form a V-shaped pressing surface. The support member (1) has a mating groove (6) that mates with the V-shaped pressing surface. The longitudinal section of the mating groove (6) is V-shaped. The two inner sides of the mating groove (6) form an included angle. The lower part of the two inner sides of the mating groove (6) is connected by an arc-shaped mating surface (7) to form a V-shaped mating surface. The included angle between the two inner sides of the mating groove (6) is greater than the included angle between the two outer sides of the pressing member (2). After the pressing surface of the pressing member (2) enters the mating groove (6), a accommodating space (8) is formed between the outer side of the pressing member (2) and the inner side of the mating groove (6) on the same side, which allows the non-folded edge area of the packaging paper tray mother plate to be freely accommodated. One side of the support member (1) is provided with a limiting plate (4) connected to the mounting bracket. The other side of the support member (1) is provided with at least two limiting posts (5) that cooperate with the limiting plate (4) to limit the packaging paper tray mother plate. The distance between the limiting plate (4) and the limiting post (5) is adjustable.
2. A packaging paper tray pre-edging device according to claim 1, characterized in that: The packaging paper tray mother plate is a rectangular strip of paper with foldable edges. When the packaging paper tray mother plate is in the finished feeding state, it is located at the top of the groove of the mating groove (6). The width of the packaging paper tray mother plate is greater than the top groove width of the mating groove (6). The packaging paper tray mother plate is positioned by the adjustable spacing limiting plate (4) and the limiting post (5). The area of the packaging paper tray mother plate to be folded, the arc transition surface (3) and the arc mating surface (7) are located on the same longitudinal vertical plane.
3. A packaging paper tray pre-edging device according to claim 1 or 2, characterized in that: The difference between the angle formed between the two inner sides of the mating groove (6) and the angle formed between the two outer sides of the pressing member (2) is less than 60° and greater than 20°.
4. A pre-flanging apparatus for a packaging paper tray according to claim 1 or 2, characterized in that: The included angle between the two inner sides of the mating groove (6) is less than 100° and greater than 40°.
5. A packaging paper tray pre-edging device according to claim 3, characterized in that: The included angle between the two inner sides of the mating groove (6) is less than 100° and greater than 40°.
