Description

Technical Field

[0001] This utility model relates to the technical field of paperboard feeding devices, specifically a paperboard printing machine feeding device. Background Technology

[0002] A modern printing press is a machine for printing text and images. It generally consists of mechanisms such as plate mounting, inking, printing, and paper feeding. Its working principle is as follows: First, the text and images to be printed are made into a printing plate and mounted on the printing press. Then, ink is applied to the areas of the printing plate with text and images by hand or by the printing press. The ink is then transferred directly or indirectly to paper or other printing substrates, such as textiles, metal plates, plastics, leather, wood boards, cardboard, glass, and ceramics, thereby reproducing a printed product identical to the printing plate.

[0003] A search revealed a patent, CN213679131U, which discloses a paperboard output device for a printing machine. This device includes a flattening table, a pushing mechanism, a leveling mechanism, and a receiving mechanism. The flattening table has a movable groove. The pushing mechanism includes a movable block, a reciprocating lead screw passing through the movable block, a rotary motor driving the reciprocating lead screw, and a push plate fixedly connected to the movable block. The leveling mechanism includes a support frame, a first cylinder mounted on the support frame, a first drive rod connected to the first cylinder, and a pressure plate fixedly connected to the end of the first drive rod. The receiving mechanism includes a receiving box, a second drive rod connected to the receiving box, and a second cylinder connected to the second drive rod. This invention uses the leveling mechanism to flatten the printed paperboard, and the pushing mechanism pushes the flattened paperboard into the receiving mechanism. The receiving mechanism ensures proper paperboard stacking, completely replacing manual labor, reducing labor costs, and improving production efficiency.

[0004] The aforementioned patents have significant beneficial effects, but in practical application, they still have the following shortcomings:

[0005] The aforementioned comparative documents describe flattening the cardboard at the printing press outlet by feeding it onto a flattening table and driving a pressure plate downwards. However, in actual operation, the printing press prints the cardboard at a relatively high speed, resulting in a fast output speed of the cardboard at the printing press outlet. Furthermore, the flattening process in the aforementioned comparative documents requires the pressure plate to move up and down and remain stationary for a period of time, thus slowing down the output speed of the printed cardboard and reducing the cardboard output efficiency of the printing press. Therefore, there is an urgent need in the art to improve the cardboard printing press output device to overcome the shortcomings of the prior art. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] Please see Figures 1-9 A paperboard printing machine discharge device includes a support base 1. Two symmetrical vertical support plates 2 are fixedly connected to the upper surface of the support base 1. Rotary disks 3 are rotatably connected to the opposite sides of the two vertical support plates 2. Several flattening frames 4 are rotatably connected between the two rotary disks 3. A drive unit 5 for rotating the two rotary disks 3 is provided on one side of the vertical support plate 2. When the drive unit 5 drives the two rotary disks 3 to rotate, each flattening frame 4 is horizontal. Each flattening frame 4 is provided with a flattening unit 6 for flattening the paperboard. The upper surface of the support base 1 is also provided with a positioning unit 7 located on one side of the two vertical support plates 2. A first electric telescopic device 9 is fixedly installed on the upper surface of the support base 1. A tray 8 adapted to the positioning unit 7 is fixedly installed at the telescopic end of the first electric telescopic device 9. An ejection unit for pushing the paperboard onto the tray 8 is provided inside the flattening frame 4.

[0032] Specifically, the support base 1 is installed at the discharge port of the cardboard printing machine. The printed cardboard is conveyed by a conveyor belt or placed in the uppermost flattening frame 4 by a robotic arm. After the printed cardboard is placed in the uppermost flattening frame 4, the cardboard conveying is paused, and the drive unit 5 is started. The drive unit 5 drives the two rotary disks 3 to rotate. When the drive unit 5 rotates, the flattening frame 4 rotates horizontally. At the same time, the flattening unit 6 is started to flatten the cardboard located in the flattening frame 4. When the rear flattening frame 4 moves to the top, the drive unit 5 is stopped, and the printed cardboard is placed in the uppermost flattening frame 4 again. The paperboard is conveyed sequentially, and the flattening frame 4 continues to convey and flatten the paperboard. When one of the flattening frames 4 moves to a position that matches the pallet 8, the push-out unit inside the flattening frame 4 is activated to push the flattened paperboard onto the pallet 8. At the same time, the positioning unit 7 positions the paperboard on the pallet 8. When there are many paperboards on the pallet 8, the first electric telescopic device 9 moves down intermittently. The paperboard printed by the printing press is intermittently conveyed through several flattening frames 4, and the paperboard is kept flattened throughout the conveying process, thereby improving the output efficiency of the printing press paperboard.

[0033] As a technical optimization of this utility model, the drive unit 5 includes a first drive motor 10 fixedly installed on one side of the vertical support plate 2. The output end of the first drive motor 10 is fixedly connected to a rotating shaft 11 fixedly connected to two rotating disks 3. A first gear 12 sleeved on the side of the rotating shaft 11 is fixedly connected to one side of the vertical support plate 2. Each flattening frame 4 is fixedly connected to a connecting shaft 13 that passes through the rotating disk 3 on the opposite side. Several second gears 14 fixedly connected to the side of the connecting shaft 13 are rotatably connected inside the rotating disk 3. Several third gears 15 located between the first gear 12 and the second gear 14 are rotatably connected to the inner side wall of the rotating disk 3. The third gears 15 mesh with both the first gear 12 and the second gear 14.

[0034] Specifically, when the rotating disk 3 needs to be rotated, the first drive motor 10 is started. The output end of the first drive motor 10 drives the rotating shaft 11 to rotate, and the rotating shaft 11 drives the two rotating disks 3 to rotate. When the rotating disk 3 rotates, since the position of the first gear 12 is fixed, the rotating disk 3 drives the second gear 14 and the third gear 15 to rotate. The third gear 15 meshes with the first gear 12 and the second gear 14. Therefore, when the rotating disk 3 rotates, the second gear 14 rotates on its own axis. When the second gear 14 rotates, it drives the connecting shaft 13 to rotate. The rotating shaft 13 drives the flattening frame 4 to rotate. Therefore, when the first drive motor 10 drives the rotating disk 3 to rotate, several flattening frames 4 rotate horizontally along the rotating shaft 11 to ensure the transmission effect of the cardboard.

[0035] As a technical optimization of this utility model, the flattening unit 6 includes a flattening plate 16 located inside the flattening frame 4, and a second electric telescopic device 17 with a telescopic end fixedly installed on the upper side of the flattening frame 4 and fixedly installed on the upper surface of the flattening plate 16.

[0036] Specifically, when the cardboard needs to be flattened, the second electric telescopic device 17 is activated. The telescopic device of the second electric telescopic device 17 drives the pressing plate 16 to move down, and the pressing plate 16 flattens the cardboard located in the flattening frame 4.

[0037] As a technical optimization of this utility model, the ejection unit includes a second drive motor 18 fixedly installed in the flattening frame 4. A clearance groove 19 is provided at the bottom of the flattening frame 4. Two symmetrical drive rollers 20 are rotatably connected between opposite side walls in the clearance groove 19. A drive belt 21 is sleeved between the sides of the two drive rollers 20. Two symmetrical ejection plates 22 are fixedly connected to the sides of the drive belt 21.

[0038] Specifically, when it is necessary to transfer the flattened cardboard to the pallet 8, the second drive motor 18 is started. The output end of the second drive motor 18 drives one of the drive rollers 20 to rotate. When the drive roller 20 rotates, it drives the drive belt 21 to rotate. The drive belt 21 drives the ejector plate 22 to move. The ejector plate 22 pushes the flattened cardboard to the upper surface of the pallet 8.

[0039] As a technical optimization of this utility model, the positioning unit 7 includes two symmetrical first positioning plates 23 and a second positioning plate 24. A third drive motor 25 and a fourth drive motor 29 are fixedly installed on the side of the bearing base 1. A first sliding block 26 is fixedly connected to the lower side of the first positioning plate 23. A first sliding groove 27 adapted to the first sliding block 26 is opened on the upper surface of the bearing base 1. A bidirectional lead screw 28 with one end fixedly connected to the output end of the third drive motor 25 is rotatably connected in the first sliding groove 27. The bidirectional lead screw 28 passes through the two first sliding blocks 26 and is threadedly connected to them. A second sliding block 30 is fixedly installed at the lower end of the second positioning plate 24. A second sliding groove 31 adapted to the second sliding block 30 is opened on the upper surface of the bearing base 1. An adjusting lead screw 32 with one end fixedly connected to the output end of the fourth drive motor 29 is rotatably connected in the second sliding groove 31. The adjusting lead screw 32 passes through the second sliding block 30 and is threadedly connected to it.

[0040] Specifically, when cardboard needs to be received, the third drive motor 25 is started. The output of the third drive motor 25 drives the bidirectional lead screw 28 to rotate. The teeth on the side of the bidirectional lead screw 28 are symmetrical and opposite. When the bidirectional lead screw 28 rotates, it drives the two first positioning plates 23 to move towards or away from each other in the first sliding groove 27, which can position cardboard of different sizes. At the same time, the second positioning plate 24 also positions the other side of the cardboard to ensure the neatness of the cardboard when it slides onto the pallet 8. After the cardboard on the pallet 8 is stacked, the fourth drive motor 29 is started. The output of the fourth drive motor 29 drives the adjusting lead screw 32 to rotate. The adjusting lead screw 32 drives the second sliding block 30 to move in the second sliding groove 31. The second sliding block 30 drives the second positioning plate 24 to move. After the second positioning plate 24 is removed, the stacked cardboard can be transferred. Cardboard of different sizes can be positioned and stacked, improving the neatness and applicability of the cardboard after stacking.

[0041] As a technical optimization of this utility model, a plug-in block 33 is fixedly connected to the lower surface of the tray 8, and a plug-in groove 34 adapted to the plug-in block 33 is opened at the upper end of the first electric telescopic device 9. A limiting bolt 35 with one end threadedly connected to the side of the telescopic end of the first electric telescopic device 9 is passed through.

[0042] Specifically, the pallet 8 can be replaced according to different sizes of cardboard. The insert block 33 on the lower surface of the pallet 8 of the appropriate size is inserted into the insert groove 34 at the telescopic end of the first electric telescopic device 9, and the limiting bolt 35 passes through the side of the telescopic upper end of the first electric telescopic device 9. One end of the limiting bolt 35 is threaded to the side of the insert block 33 to install the pallet 8, which is convenient for replacing the pallet 8 according to different sizes of cardboard.

[0043] As a technical optimization of this utility model, two grooves 36 are provided on the upper side of the pallet 8. The grooves 36 facilitate the transfer of the stacked cardboard on the pallet 8 by lifting equipment (such as a forklift).

[0044] All of the electrical products mentioned above can be purchased from the market. They are mature technologies and have been fully disclosed, so they will not be repeated in the instruction manual.
