AI Technical Summary
In the existing technology, when processing the bottom layer of self-standing packaging bags, hard contact can easily lead to material breakage or surface damage, affecting product quality.
A combination of soft and hard folding trays is used to fold the bottom edge of the packaging bag first with a soft fold and then reinforce it with a hard fold. The soft folding tray prevents pressure concentration, while the hard folding tray reinforces the creases and ensures that the corners are formed.
It effectively prevents material breakage and surface damage, improves product quality, and adapts to the compression requirements of materials of different thicknesses.

Abstract
Claims
1. A device for bottom-sealing a packaging bag, comprising a bottom plate (1), characterized in that: Two limiting rods (2) are fixedly connected to the upper surface of the base plate (1). A soft folding disc (3) is rotatably connected to the outer surface of one of the limiting rods (2), and a hard folding disc (4) is rotatably connected to the outer surface of the other limiting rod (2). A base (5) is provided above the base plate (1). A first bidirectional screw (6) is rotatably connected to the inner wall of the base (5). Two mounting plates (7) are threadedly connected to the outer surface of the first bidirectional screw (6). A fixing plate (8) is fixedly connected inside each mounting plate (7). A layered plate (9) is fixedly connected to the side of each fixing plate (8) that is far away from each other. Two sliding rods (10) are fixedly connected to the inner bottom wall of the base (5). The outer surface of each sliding rod (10) is slidably connected to the inner wall of the corresponding mounting plate (7).
2. A bag bottom seal delaminating apparatus as defined in claim 1, wherein: The upper surface of the base plate (1) is fixedly equipped with mounting brackets (11) arranged at equal intervals. The inner wall of each mounting bracket (11) is rotatably connected with a second bidirectional screw (12), and the outer surface of each second bidirectional screw (12) is threaded with two threaded blocks (13).
3. A bag bottom seal delaminating apparatus as defined in claim 2, wherein: The base plate (1) is provided with two first pressing rollers (14) and two second pressing rollers (15) above it. Both ends of each first pressing roller (14) and second pressing roller (15) are rotatably connected to the side of the corresponding threaded block (13) that is close to each other.
4. The apparatus of claim 1 wherein: A fixing strip (16) is fixedly connected to the upper surface of the base plate (1), and two guide rods (17) are fixedly connected to the right side of the fixing strip (16).
5. A bag bottom seal delaminating apparatus as defined in claim 4, wherein: Each guide rod (17) has a limit block (18) fixedly connected to its right end, and the bottom surface of each limit block (18) is fixedly connected to the upper surface of the base plate (1).
6. A bag bottom seal delaminating apparatus as defined in claim 4, wherein: The base (5) has two first square blocks (19) fixedly connected to its bottom surface. The inner wall of each first square block (19) is slidably connected to the outer surface of the corresponding guide rod (17).
7. A bag bottom seal delaminating apparatus as defined in claim 4, wherein: A motor (20) is fixedly installed on the upper surface of the base plate (1). An adjusting screw (21) is fixedly connected to the output shaft of the motor (20). The left end of the adjusting screw (21) is rotatably connected to the right side of the fixing strip (16).
8. A bag bottom seal layering apparatus as defined in claim 7, wherein: The outer surface of the adjusting screw (21) is threaded with a second square block (22), and the upper surface of the second square block (22) is fixedly connected to the bottom surface of the base (5).
