DETAILED DESCRIPTION

[0016] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0017] like Figure 1 、 2 As shown in the figure, a degradable film bag-making machine for convenient discharging in this embodiment includes a frame 2, a discharging arm 1 mounted on the frame 2, and a discharging shaft mounted on the discharging arm 1 for placing a roll of degradable film. A hot cutter 6 and a discharging mechanism are sequentially mounted on the frame 2 along the direction of discharging the degradable film. A receiving mechanism 7 is located at the bottom of the hot cutter 6, and a gripping mechanism 8 is located between the receiving mechanism 7 and the discharging mechanism. A traction rubber roller group, a rear feed rubber roller group, and a front feed rubber roller group are sequentially located between the discharging shaft and the hot cutter 6. A discharging servo motor drives the discharging shaft to rotate, discharging the degradable film. The degradable film is conveyed by the traction rubber roller group, the rear feed rubber roller group, and the front feed rubber roller group to the hot cutter 6, where it is heat-cut. The heat-cut film sheets are then stacked flatly on the receiving mechanism 7 to form a film sheet. The film sheet sheet is then grabbed by the gripping mechanism 8 and transferred to the discharging mechanism, where it is discharged.

[0018] The traction rubber roller group is driven by the traction frequency conversion motor 3, the rear feeding rubber roller group is driven by the rear feeding servo motor 4, and the front feeding rubber roller group is driven by the front feeding servo motor 5.

[0019] like Figure 3As shown, the material receiving mechanism 7 includes a material receiving frame 7.2, a rotating shaft 7.1 is provided on the material receiving frame 7.2, both ends of the rotating shaft 7.1 are mounted in the frame 2 and hinged to the frame 2, and the material receiving frame 7.2 is provided with a plurality of material receiving plates 7.4 evenly distributed along the width direction of the material receiving frame 7.2, one end of the material receiving plate 7.4 is fixed to the material receiving frame 7.2, and the other end of the material receiving plate 7.4 is a free end. The receiving cylinders 7.3 are symmetrically arranged at the bottom of the receiving rack 7.2, and the receiving cylinders 7.3 drive the receiving rack 7.2 to rotate around the rotating shaft 7.1, so that the receiving plate 7.4 swings up and down, that is, the receiving plate 7.4 operates alternately between the inclined downward arrangement and the horizontal arrangement. When the receiving plate 7.4 is arranged inclined downward, the receiving plate 7.4 is in a state of receiving the sheet film group, so that the sheet film group is flat and not messy; when the receiving plate 7.4 is in a horizontal arrangement, the receiving plate 7.4 is in a material moving state, which is convenient for the grabbing mechanism to grab the sheet film group.

[0020] like Figure 4 As shown, the grabbing mechanism 8 includes a movable plate 8.8, which is positioned above the output mechanism. A grabbing mounting plate 8.13 is provided on one side of the output mechanism and extends to one side of the material receiving mechanism 7. A guide rail 8.4 extending along the entire length of the grabbing mounting plate 8.13 is provided, on which a slider 8.5 is secured. One end of the movable plate 8.8 is fixed to the slider 8.5. The movable plate 8.8 is provided with multiple sets of grabbers, which are arranged in parallel along the width of the degradable film. Parallel driven pulleys 8.2 are provided at each end of the grabbing mounting plate 8.3. A driving pulley 8.1 is provided at the output end of the grabbing servo motor. The driving pulley 8.1 and the driven pulley 8.2 are connected by a synchronous belt 8.3, which passes through the movable plate 8.8 and is fixedly connected to the movable plate 8.8. The grabbing servo motor rotates, driving the active pulley 8.1 to rotate, causing the driven pulley 8.2 and the synchronous belt 8.3 to rotate, and then driving the movable plate 8.8 and the slider 8.5 to move along the guide rail 8.4, so that the grabbing hand can move back and forth between the receiving mechanism 7 and the output mechanism 8.

[0021] The aforementioned grippers each include a fixed gripper 8.11, which is positioned between two adjacent material receiving plates 8.4. A first hinged seat 8.14 and a second hinged seat 8.6 are positioned on the top surface of the fixed gripper 8.11. A movable gripper 8.10 is positioned above the fixed gripper 8.11, positioned vertically opposite the movable gripper 8.10. One end of the movable gripper 8.10 is hinged to the first hinged seat 8.14. A gripping cylinder 8.7 is positioned between the movable gripper 8.10 and the second hinged seat 8.6. The cylinder end of the gripping cylinder 8.7 is hinged to the second hinged seat 8.6, and the extended end of the gripping cylinder 8.7 is connected to the movable gripper 8.10 via a connecting rod 8.9. The grabbing cylinder 8.7 drives the movable gripper 8.10 to rotate around the hinge point, so that the movable gripper 8.10 approaches the fixed gripper 8.11 to grab the sheet membrane group, or the movable gripper moves away from the fixed gripper to release the sheet membrane group.

[0022] The bottom of the movable grippers are provided with rubber pads 8, 12 respectively, which have a protective effect on the film assembly.

[0023] The output mechanism includes an output frame 10, and two parallel output shafts are provided at both ends of the output frame 10. An output belt 9 is sleeved between the two output shafts. The output frequency conversion motor 11 drives one output shaft to rotate, driving the other output shaft and the output belt 9 to rotate, so that the output belt 9 outputs the film group.

[0024] The film is received by the receiving mechanism, so that the film group is flatly placed on the receiving plate, and then the film group is grabbed by the grabbing mechanism and moved to the output mechanism for output. The application is easy to operate, convenient for discharging, and improves production efficiency.

[0025] In addition to the above embodiments, the present invention also includes other implementation methods. Any technical solutions formed by equivalent transformation or equivalent replacement should fall within the scope of protection of the claims of the present invention.
