[0019] It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.
[0020] Reference Figure 1-3This invention discloses an embodiment of a folding device for processing film printed products, comprising two horizontally arranged and parallel side frames 1. A first movable plate 3, movable along its length, is disposed between the front parts of the two side frames 1. An extension plate is horizontally fixedly connected to the rear end of the first movable plate 3. A pressing structure is disposed on the first movable plate 3. A first overlapping plate with its rear end inclined downward is fixedly connected between the front parts of the two side frames 1 and located below the first movable plate 3. A horizontally arranged... A second movable plate 14, which can move along its length, is provided between the two side frames 1 and at the rear of the second movable plate 8. A plurality of electrically controlled grippers 15 are provided on the front surface of the second movable plate 14. A third movable plate 17, which can move along the length of the side frame 1, is provided between the two side frames 1 and at the lower part of the second movable plate 14. A receiving plate 19 is horizontally fixedly connected to the rear end between the two side frames 1. A third movable plate 18, which is the same height as the first movable plate 7 and tilts downward at the rear end, is fixedly connected between the two side frames 1 and at the front of the receiving plate 19.
[0021] The front of the two side frames 1 is provided with a feeding structure, which includes a fixed frame 22 set at the front of the two side frames 1. The front of the fixed frame 22 is provided with a discharge roller 23. The middle of the fixed frame 22 is provided with multiple guide rollers 24. The upper rear surface of the fixed frame 22 is horizontally fixedly connected with a feeding plate 25. The two rear surfaces of the fixed frame 22 are both fixedly connected with multiple fixed seats 27. The multiple fixed seats 27 on both sides correspond to each other. The two corresponding fixed seats 27 are horizontally rotatably connected with a pusher roller 28. The rear end of the fixed frame 22 is provided with a cutting device 26.
[0022] In use, one end of the film material is pushed into the space between the two side frames 1 by the feeding structure. The material overlaps the first overlapping plate 7 to prevent contamination from contact with the ground. Then, the pressing structure on the first movable plate 3 presses the material down, and simultaneously, the first movable plate 3 moves backward a certain distance. The moved film material then rests on the second overlapping plate 8. The cutting device 26 then cuts the film. Half of the cut film material lies below the first movable plate 3, and the other half lies above it, thus achieving the first fold. The second movable plate 8 then... Multiple electrically controlled grippers 15 on the moving plate 14 clamp the folded end of the film and drive it to move backward a certain distance. During this process, the film material in front extends to the front of the third moving plate 17 and overlaps the third overlapping plate 18, while the film material in the rear is located at the rear of the third moving plate 17. At this time, the third moving plate 17 moves backward, driving the film material to move synchronously. The film in front and behind it will be folded up again. When it moves to the receiving plate 19, the film material that has been folded twice can be removed, and the next round of film folding operation can be started again, thus realizing automated batch film folding processing.
[0023] The discharge roller 23 is used to install the film raw material roller. Multiple guide rollers 24 can play a guiding role to ensure the tension of the film during the conveying process. The main body of the cutting device 26 is a rectangular gantry frame with an electrically controlled telescopic rod on its upper part. The piston rod of the electrically controlled telescopic rod is vertically fixed to the bottom end of the cutting blade. The upper surface of the feeding plate 25 is also provided with a cutting groove corresponding to the cutting blade to ensure that it can completely cut the film when cutting it.
[0024] Furthermore, servo motors 29 are fixedly connected to the outer ends of multiple fixed seats 27 on one side. The output shafts of the multiple servo motors 29 rotatably pass through one side surface of the multiple fixed seats 27 and are fixedly connected to one end of the multiple pusher rollers 28 respectively.
[0025] Multiple servo motors 29 operate synchronously, and the rotation of their output shafts drives the pusher rollers 28 to rotate, which in turn pushes the film toward the rear of the device under the action of friction.
[0026] Furthermore, the pressing structure includes a first gantry 4 fixedly connected to the front of the upper surface of the first movable plate 3. A plurality of first electrically controlled telescopic rods 5 are vertically fixedly connected to the top of the first gantry 4. The bottom ends of the piston rods of the plurality of first electrically controlled telescopic rods 5 can movably pass through the top of the first gantry 4 and extend downward. A pressure strip 6 is horizontally fixedly connected to the bottom ends of the piston rods of the plurality of first electrically controlled telescopic rods 5.
[0027] In the pressing structure, the piston rod of the first electrically controlled telescopic rod 5 is extended, which drives the pressure bar 6 to descend. The pressure bar 6 presses down and fixes the film, and the film is fixed under the action of friction.
[0028] Furthermore, each of the two side frames 1 has a first electric slide rail 2 horizontally fixedly connected to the opposite side surface at the front, and a first movable plate 3 horizontally fixedly connected between the two first electric slide rails 2. The upper and lower parts of the opposite side surfaces at the rear of the two side frames 1 are respectively horizontally fixedly connected to a second electric slide rail 13 and a third electric slide rail 16. A second movable plate 14 is horizontally fixedly connected to the upper surface of the sliding part of the two second electric slide rails 13, and a third movable plate 17 is horizontally fixedly connected to the upper surface of the sliding part of the two third electric slide rails 16.
[0029] The horizontal movement of the first movable plate 3, the second movable plate 14, and the third movable plate 17 is controlled by the first electric slide rail 2, the second electric slide rail 13, and the third electric slide rail 16, respectively.
[0030] Furthermore, both sides of the rear end of the upper surface of the second overlapping plate 8 are vertically fixedly connected to the support 9, and the upper part of the two supports 9 is horizontally fixedly connected to the horizontal shaft 10. The middle part of the outer surface of the horizontal shaft 10 is horizontally rotatably connected to the rotating roller, the two ends of the rotating roller are fixedly connected to the extension arm 11, and the two extension arms 11 are horizontally rotatably connected to the pressure roller 12.
[0031] When the first movable plate 3 moves the film backward, it will pass through the pressure roller 12. The pressure roller 12, under its own gravity, always applies a downward force to the film, which has a flattening effect on the film.
[0032] Furthermore, a second gantry 20 is fixedly connected to the rear end of the upper surface of the two side frames 1. A plurality of second electrically controlled telescopic rods 21 are vertically fixedly connected to the top of the second gantry 20. The bottom ends of the piston rods of the plurality of second electrically controlled telescopic rods 21 can movably pass through the second gantry 20 and extend downward. A lower pressure block is fixedly connected to the bottom ends of the piston rods of the plurality of second electrically controlled telescopic rods 21.
[0033] After the fully folded film moves onto the receiving plate 19, the piston rods of multiple second electrically controlled telescopic rods 21 extend, and multiple pressing blocks press down on the front end of the folded film. Then, the third movable plate 17 resets to prevent the film from being taken away during the reset process.
[0034] In use, one end of the film material is pushed into the space between the two side frames 1 by the feeding structure. The material overlaps the first overlapping plate 7 to prevent contamination from contact with the ground. Then, the pressing structure on the first movable plate 3 presses the material down, and simultaneously, the first movable plate 3 moves backward a certain distance. The moved film material then rests on the second overlapping plate 8. The cutting device 26 then cuts the film. Half of the cut film material lies below the first movable plate 3, and the other half lies above it, thus achieving the first fold. The second movable plate 8 then... Multiple electrically controlled grippers 15 on the moving plate 14 clamp the folded end of the film and drive it to move backward a certain distance. During this process, the film material in front extends to the front of the third moving plate 17 and overlaps the third overlapping plate 18, while the film material in the rear is located at the rear of the third moving plate 17. At this time, the third moving plate 17 moves backward, driving the film material to move synchronously. The film in front and behind it will be folded up again. When it moves to the receiving plate 19, the film material that has been folded twice can be removed, and the next round of film folding operation can be started again, thus realizing automated batch film folding processing.
[0035] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
