Description

Technical Field

[0001] The utility model relates to the technical field of paper palletizing, and more specifically, to a paper stack positioning device for a paper cutting machine. Background Art

[0002] A paper cutting machine is used to handle the paper cutting requirements in the later stage of printing. The cut paper needs to be palletized. This process requires the assistance of a positioning device to avoid the occurrence of offset during the paper palletizing process. The actual use has the advantages of simple operation, stable structure, and good positioning effect.

[0003] The prior art discloses a paper cutting machine blanking and palletizing auxiliary device with the publication number: CN219058058U. For the above-mentioned utility model, the positioning and alignment of the paper stack need to be achieved by means of the first side folding plate, the second side folding plate and the aligned rear plate that move towards each other. During this operation process, the opposite surfaces of the first side folding plate, the second side folding plate and the aligned rear plate are easily adhered with debris on the surface of the paper stack. Cleaning them will consume a certain amount of time. If not cleaned, the adhered debris will affect the positioning of the next batch of paper stacks, reducing the practicality of this utility model. At the same time, when the first side folding plate, the second side folding plate and the aligned rear plate align the paper stack, it is easy to cause the protruding paper to be folded in half. It is difficult for the operator to observe whether there is a protruding paper that has been folded in half, which brings inconvenience to the alignment and observation of the new type of paper stack.

[0004] In view of the problems in the related art, no effective solution has been proposed yet. Summary of the Utility Model

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the present utility model provides a paper stack positioning device for a paper cutter, which has the following beneficial effects:

[0017] (1) The utility model adopts a concave-shaped frame. When actually using the paper stack positioning device of the paper cutter, the externally connected movable tray drives the paper stack close to the vertical plate. When the paper stack touches the vertical plate, one side of the paper stack can be aligned. Then, by using the control panel, the forward and reverse motor works. The output end of the forward and reverse motor drives the bidirectional lead screw to rotate. Since the bidirectional lead screw is in threaded cooperation with the two lead screw sleeves, the rotating bidirectional lead screw can push the two lead screw sleeves closer to or away from each other. When the two lead screw sleeves move closer to each other, the two lead screw sleeves drive the two concave-shaped frames to move towards each other through the two socket plates and the four connecting rods. The two concave-shaped frames respectively drive the two rectangular blocks to move towards each other. The two rectangular blocks moving towards each other can position and align the remaining two sides of the paper stack. After the paper stack is aligned and positioned, the externally connected movable tray is reset, and the forward and reverse motor continues to work. The two rectangular blocks that continue to move towards each other can scrape off the debris adsorbed on one side of the vertical plate. After scraping is completed, by using the control panel, the output end of the forward and reverse motor rotates in the reverse direction. When the two concave-shaped frames move away from each other and reset, by using the control panel, the two self-locking motors work. The two self-locking motors respectively drive the two mounting shafts to rotate. The two rotating mounting shafts can respectively drive the two rectangular blocks and the two indicator plates to rotate. The two scale marks can know the rotation angles of the two mounting shafts. When the two rectangular blocks rotate 90 degrees, the two self-locking motors are stopped. At this time, one side of the two rectangular blocks can be pre-cleaned. The cross bar can ensure the stability of the horizontal movement of the two socket plates. By setting the concave-shaped frame, without affecting the alignment of the paper stack, the debris on the surface of the alignment structure can be quickly cleaned, improving the practicability of the paper stack positioning device of the paper cutter.

[0018] (2) The utility model adopts a first air storage cylinder and a second air storage cylinder. According to the above operations, when the paper stack is aligned and positioned, the externally connected movable tray is reset. At the same time, by using the control panel, the output end of the forward and reverse motor rotates in the reverse direction, and the two concave-shaped frames will move away from each other. At the same time, by using the control panel, the air pump works, and six electromagnetic valves are opened and closed at the same time. The air inside the air storage tank can enter the interiors of the four first air storage cylinders and the two second air storage cylinders respectively through the six connecting hoses. The air inside the four first air storage cylinders and the two second air storage cylinders can be ejected through multiple air ejection pipes. The ejected air can blow the protruding and folded paper. The operator can easily observe the shaking protruding and folded paper. Multiple pressure valves can ensure the strength of the air ejected through the multiple air ejection pipes. By setting the first air storage cylinder and the second air storage cylinder, it can help the operator observe whether there is protruding paper that is folded, bringing convenience to the alignment observation of the paper stack of the paper stack positioning device of the paper cutter.

Only its use is involved without modification, so the control method and circuit connection will not be described in detail.

[0035] Working principle:

[0036] When actually using the paper stack positioning device of the paper cutter, the externally connected moving tray drives the paper stack to approach the vertical plate 2. When the paper stack contacts the vertical plate 2, one side of the paper stack can be aligned. Then, using the control panel, the forward and reverse motor 22 is operated. The output end of the forward and reverse motor 22 drives the bidirectional lead screw 4 to rotate. Since the bidirectional lead screw 4 is in threaded engagement with the two sets of lead screw sleeves 5, the rotating bidirectional lead screw 4 can push the two sets of lead screw sleeves 5 closer to or farther away from each other. When the two sets of lead screw sleeves 5 approach each other, the two sets of lead screw sleeves 5 drive the two sets of concave frames 9 to move towards each other through the two sets of socket plates 6 and the four sets of connecting rods 8. The two sets of concave frames 9 respectively drive the two sets of rectangular blocks 13 to move towards each other. The two mutually moving rectangular blocks 13 can position and align the remaining two sides of the paper stack. After the paper stack is aligned and positioned, the externally connected moving tray is reset, and the forward and reverse motor 22 continues to work. The two continuously moving rectangular blocks 13 can scrape off the debris adsorbed on one side of the vertical plate 2. After the scraping is completed, using the control panel, the output end of the forward and reverse motor 22 rotates in the reverse direction. When the two sets of concave frames 9 move away from each other and reset, using the control panel, the two self-locking motors 14 are operated. The two self-locking motors 14 respectively drive the two sets of mounting shafts 12 to rotate. The two rotating mounting shafts 12 can respectively drive the two sets of rectangular blocks 13 and the two sets of indicating plates 16 to rotate. The two scale marks 15 can be used to know the rotation angle of the two sets of mounting shafts 12. When the two sets of rectangular blocks 13 rotate by ninety degrees, the two self-locking motors 14 are stopped. At this time, one side of the two sets of rectangular blocks 13 can be cleaned in advance. The cross bar 7 can ensure the stability of the horizontal movement of the two sets of socket plates 6. Through the provided concave frame 9, without affecting the alignment of the paper stack, the debris on the surface of the alignment structure can be quickly cleaned, improving the practicability of the paper stack positioning device of the paper cutter. At the same time, according to the above operations, when the paper stack is aligned and positioned, the externally connected moving tray is reset. At the same time, using the control panel, the output end of the forward and reverse motor 22 rotates in the reverse direction, and the two sets of concave frames 9 will move away from each other. At the same time, using the control panel, the air pump 18 is operated, and the six solenoid valves 21 are opened and closed at the same time. The air inside the air storage tank 17 can enter the interiors of the four first air storage cylinders 11 and the two second air storage cylinders 23 respectively through the six connecting hoses 19. The air inside the four first air storage cylinders 11 and the two second air storage cylinders 23 can be ejected through the multiple air ejection pipes 20. The ejected air can blow the protruding and folded paper, and the operator can easily observe the shaking protruding and folded paper. The multiple pressure valves can ensure the strength of the air ejected through the multiple air ejection pipes 20. Through the provided first air storage cylinders 11 and second air storage cylinders 23, it can help the operator observe whether there is protruding paper that is folded, bringing convenience to the alignment observation of the paper stack of the paper stack positioning device of the paper cutter.
