Description

Technical Field

[0001] This utility model belongs to the technical field of mulch film production equipment, and specifically relates to an automatic weighing device for mulch film rolls. Background Technology

[0002] As an important agricultural production material, the use of plastic film is constantly increasing. Plastic film production technology has advanced to the point where efficient roll production is now possible. After the film is rolled, it needs to be transported to an electronic scale for weighing; manual handling is inefficient.

[0003] Chinese utility model patent (CN221404459U) discloses a rapid weighing device for rolled mulch film, including a pressure sensor and a roller mill. The roller mill includes a frame and multiple parallel rollers rotatably connected to the frame. The frame is mounted on one side of the winding machine and has four support legs at the bottom. The pressure sensor is mounted on the bottom of the four support legs and electrically connected to a display device. One side of the roller mill abuts against a mounting platform. A slope transition plate is installed between the mounting platform and the rollers. The slope transition plate includes a sloping surface, a buffer slope, and a vertical plate surface that are fixedly connected in sequence. The inclination angle of the sloping surface is greater than that of the buffer slope. The vertical plate surface is fixedly connected to the side of the frame by screws, and a vertical strip-shaped through hole is provided at the screw connection point. The wound mulch film is directly moved onto the roller mill for weighing via the rollers, and then moved onto the mounting platform via the slope transition plate for bagging and packaging. Although this patent solves the handling problem, it still requires manual movement of the mulch film rolls. When the mulch film is pushed onto the roller mill, there is a risk that the mulch film may roll off the roller mill. Based on this, we propose an automatic weighing device for plastic film rolls.
