[0001] The utility model relates to the technical field of thin films, in particular to a waste material recovery device for film trimming. Background Art
[0002] During the production process of plastic film through the blown film unit, due to the matching production between the mold and the hot roller, the edges of the film often appear too thin, too thick or have bad edges. In order to produce qualified film products that meet customer order requirements, the edges of the film need to be cut. The film on the production line is cut by the trimming device. The film edge material is in strip shape, and the film edge material still has use value after later processing, so a recycling device is needed for unified collection.
[0003] The existing waste recycling device for film trimming usually recycles the film edge materials after rewinding. Since the cut film edge materials have different widths, the rewinding rollers cannot match during rewinding, and multiple groups of rewinding rollers cannot work at the same time during rewinding, resulting in low rewinding efficiency. Utility Model Content

Since the widths of the cut film edge materials are different, the winding rollers cannot match during winding, and multiple groups of winding rollers cannot work at the same time during winding, resulting in low winding efficiency. A waste recovery device for film trimming is proposed.
[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0006] A waste recycling device for film trimming comprises a vertical plate, a bottom plate is installed on one side of the vertical plate, and a motor is installed on the top of the bottom plate, a gear box is installed on one side of the vertical plate, one end of the motor is connected to a gear, and a transmission shaft is installed on one side of the gear, a hollow rotating shaft is installed on the inner side of the vertical plate, one end of the transmission shaft is provided with a groove, and the inside of the groove is connected to a protrusion, one end of the protrusion is connected to a connecting shaft, and a winding roller is installed on one end of the connecting shaft, a fixing bolt is installed on the top of the transmission shaft, and a nut is installed on the outer side of the fixing bolt.
[0007] Preferably, the transmission shaft forms a rotating structure through gears and a motor, and the transmission shaft is connected to the inside of the hollow rotating shaft.
[0008] Preferably, the transmission shaft is connected to the connecting shaft via a protrusion, and the outer diameter of the protrusion is smaller than the inner diameter of the groove.
[0009] Preferably, the fixing bolt is threadedly connected to the transmission shaft and the protrusion, and the protrusion is fixedly connected to the connecting shaft.
[0010] Preferably, the motor is connected to the vertical plate via a bottom plate, and the bottom plate and the vertical plate are vertical.
[0011] Preferably, the gear box is fixedly connected to the vertical plate.
[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:
[0013] 1. In the utility model, the film edge material is wound on the outside of the winding roller. After winding, the motor is started, and the gears are driven by the motor to rotate, so that multiple sets of gears rotate at the same time. When the gears rotate, the winding roller is driven to rotate through the transmission shaft and the connecting shaft, so that all subsequent films are wound on the winding roller, and the film edge material is recovered. By driving multiple sets of winding rollers to rotate simultaneously through multiple sets of gears, multiple sets of film edge materials can be recovered at the same time, thereby increasing the recycling efficiency.
[0014] 2. In the utility model, when it is necessary to recycle film scraps of different widths, personnel can remove the nut from the fixing bolt, and then remove the fixing bolt from the transmission shaft, so that the transmission shaft and the connecting shaft can be separated. After separation, the winding roller can be replaced. After replacing the appropriate winding roller, it can be recycled. BRIEF DESCRIPTION OF THE DRAWINGS
