AI Technical Summary
Existing asphalt packaging equipment requires manual assistance to open the bag opening during filling, which is impractical.
An asphalt packaging bag filling device was designed, which includes an expansion structure. A double-output shaft motor drives a bevel gear and a bidirectional threaded shaft to move a slider and an adjusting rod. With the help of a spring and a squeezing rod, the packaging bag opening is automatically expanded to a square shape for filling.
It enables automatic opening of asphalt packaging bags, improving the practicality and stability of the filling equipment and ensuring smooth filling operations.

Abstract
Claims
1. A bitumen bag filling apparatus comprising a bitumen filling apparatus body (1), characterised in that: The asphalt filling equipment body (1) is equipped with a base (2), and a U-shaped frame plate (3) is fixedly installed on one side of the asphalt filling equipment body (1). Two movable and adjustable sliders (4) are installed at both ends of the U-shaped frame plate (3). An adjustable rod (5) is installed in the middle of each of the four sliders (4). A pull rod (6) is fixedly installed at the top end of each of the four adjustment rods (5) located inside the top of the U-shaped frame plate (3). A packaging bag body (7) is provided at the top of the base (2) and inside the U-shaped frame plate (3). A sling (8) is installed on both sides of the packaging bag body (7). The four slings (8) are hooked onto the four adjustment rods (5) and limited by the pull rods (6).
2. The asphalt bag filling apparatus of claim 1, wherein: Both ends of the U-shaped frame plate (3) are provided with sliding through grooves (9). Two bidirectional threaded shafts (10) are rotatably installed inside the two sliding through grooves (9). Two sliders (4) at the ends of the U-shaped frame plate (3) are slidably installed inside the sliding through grooves (9) and threadedly connected to both sides of the bidirectional threaded shafts (10). Two inner grooves (11) are symmetrically opened inside the U-shaped frame plate (3). One end of the two bidirectional threaded shafts (10) extends into the two inner grooves (11) respectively and is fixedly installed with bevel gear one (12). A double-output shaft motor (13) is installed in the middle of the U-shaped frame plate (3). The two output ends of the double-output shaft motor (13) extend into the two inner grooves (11) respectively and are fixedly installed with bevel gear two (14). Bevel gear two (14) meshes with bevel gear one (12).
3. The asphalt bag filling apparatus of claim 1, wherein: Each of the four sliders (4) has a cross-shaped through groove (15) in the middle of its upper part. An adjusting rod (5) is installed through the cross-shaped through groove (15). A square slider (16) is fixedly connected to the surface of the adjusting rod (5) inside the cross-shaped through groove (15). At the same time, a spring (17) is sleeved on the surface of the adjusting rod (5) inside the cross-shaped through groove (15). The two ends of the spring (17) are fixedly connected to the square slider (16) and the cross-shaped through groove (15) respectively.
4. The asphalt bag filling apparatus of claim 3, wherein: The four adjusting rods (5) are all fixedly installed with extrusion rods (18) at the top of the outer side of the U-shaped frame plate (3). Extrusion plates (19) are symmetrically fixedly installed on the upper part of both sides of the U-shaped frame plate (3). The extrusion plates (19) are provided with inclined structures for extruding the extrusion plates (19).
