Description

Technical Field

[0001] This utility model relates to the field of printing equipment technology, and in particular to a paper feeding device for a paper mounting machine. Background Technology

[0002] Paper laminating machines belong to the field of paper product manufacturing machinery. In particular, a type of paper laminating machine is used to glue two sheets of paper together. It is also known in the industry as a laminating machine or pasting machine. It is used to glue and bond pre-printed color paperboard and cardboard, etc. It is an important supporting equipment for the production of pre-printed paper boxes.

[0003] The existing Chinese patent with publication number CN210884410U discloses a feeding device for a paper mounting machine. The existing technical solution mentioned above has the following defects. Although the above technical solution uses a paper suction assembly and pressure rollers to transport the paperboard, it can ensure that the paperboard can be output smoothly and avoid the paperboard from arching. At the same time, the setting of a limit strip can ensure that the paperboard can be fed out one piece at a time. However, in the above technical solution, the paperboard is placed directly on the conveyor, and there is no limit mechanism to limit the paperboard on the conveyor. This can easily cause the paperboard to tilt and deviate on the conveyor, thereby reducing the conveying effect of the paperboard. Utility Model Content

[0027] Please refer to Figure 1-4A paper-feeding device for a paper-mounting machine includes a conveyor 1. Baffles 6 are provided on both sides of the top surface of the conveyor 1, and a connecting plate 7 is provided between the baffles 6. A first motor 8 is installed at the middle position of the front end surface of the connecting plate 7, and a bidirectional lead screw 20 is fixedly connected to the output end of the first motor 8. A second moving block 21 is provided on the bidirectional lead screw 20, and a limiting plate 5 is provided on the bottom surface of the second moving block 21. A limiting rod 22 is provided between the connecting plates 7 on the second moving block 21. An upper... The material bin 2 has a side plate 10 on one side of its top surface. An electric cylinder 11 is mounted on one side of the side plate 10, and a push plate 9 is fixedly connected to the output end of the electric cylinder 11. A mounting frame 15 is provided on one side of the material bin 2, and a second motor 12 is mounted on the top surface of the mounting frame 15. A screw 13 is provided through the mounting frame 15 at the output end of the second motor 12, and a first moving block 18 is provided on the screw 13. A through groove is opened on one side of the first moving block 18 through the side surface of the material bin 2. The 16 is provided with a fixing block 17, one end of which is located inside the feeding box 2 and a feeding plate 3 is provided. A connecting block 19 is provided on one side surface of the first moving block 18, and one end of the connecting block 19 extends into the connecting groove 14 opened on one side of the inner wall of the mounting frame 15. When the cardboard is placed in the feeding box 2, the second motor 12 on the top surface of the mounting frame 15 is turned on. The second motor 12 drives the screw 13 to rotate. By using the connecting block 19 and the connecting groove 14, the first moving block 18 on the screw 13 can be limited, so that the first moving block 18 can move on the screw 13. While the first moving block 18 is moving, the feeding plate 3 is moved by the fixing block 17, so that the cardboard in the feeding box 2 can be automatically moved upward and fed. Then, by opening the electric cylinder 11 on one side surface of the side plate 10, the electric cylinder 11 drives the push plate 9 to move, so that the cardboard can be automatically pushed onto the conveyor 1, thus automatically pushing and feeding the cardboard, which helps to improve its working efficiency.

[0028] In one embodiment, the bottom surface of the conveyor 1 is provided with support legs 4 on both sides. There are multiple support legs 4, and the multiple support legs 4 are evenly distributed in pairs on both sides of the bottom surface of the conveyor 1. The support legs 4 are fixedly welded to the conveyor 1. The support legs 4 support the conveyor 1, which helps to improve the stability of the conveyor 1.

[0029] In one embodiment, the length and width of the feeding plate 3 are smaller than the length and width of the feeding box 2. The feeding plate 3 is movably connected to the feeding box 2, which allows the feeding plate 3 to move within the feeding box 2, thereby automatically feeding the cardboard into the feeding box 2.

[0030] In one embodiment, there are two second moving blocks 21, which are evenly distributed on the bidirectional lead screw 20. The second moving blocks 21 are movably connected to the limiting rod 22. By using the first motor 8, the bidirectional lead screw 20, the limiting rod 22, and the second moving blocks 21, the positional distance between the two limiting plates 5 can be adjusted, thereby limiting cardboard of different sizes and improving the adaptability of the device.

[0031] In one embodiment, the fixing block 17 and the through groove 16 are rectangular structures. The fixing block 17 and the through groove 16 are slidably connected, so that the fixing block 17 can move in the through groove 16, thereby driving the feeding plate 3 at one end of the fixing block 17 to move.

[0032] In one embodiment, the limiting plate 5 is located above the conveyor 1. The limiting plate 5 is matched with the conveyor 1 and can move normally, thereby blocking and limiting the cardboard on the conveyor 1 to prevent the cardboard from falling during the conveying process.

[0033] In one embodiment, the connecting block 19 and the connecting groove 14 are rectangular structures, and the connecting block 19 and the connecting groove 14 are slidably connected. The use of the connecting block 19 and the connecting groove 14 can limit the first moving block 18, thereby facilitating the normal movement of the first moving block 18 on the screw 13.

[0034] In one embodiment, the control circuit of the control panel can be implemented by simple programming by those skilled in the art, which is common knowledge in the field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0035] Working principle:

[0036] In use, the cardboard is placed in the feeding box 2. The second motor 12 on the top surface of the mounting frame 15 is turned on, and the second motor 12 drives the screw 13 to rotate. By using the connecting block 19 and the connecting groove 14, the first moving block 18 on the screw 13 can be limited, allowing the first moving block 18 to move on the screw 13. While the first moving block 18 is moving, it drives the feeding plate 3 to move through the fixing block 17, thereby automatically feeding the cardboard in the feeding box 2. Then, by turning on the electric cylinder 11 on one side surface of the side plate 10, the electric cylinder 11 drives the push plate 9 to move, thereby automatically pushing the cardboard onto the conveyor 1. This automatic feeding of the cardboard improves its working efficiency. The first motor 8 drives the bidirectional lead screw 20 to rotate. The limiting rod 22 between the connecting plates 7 limits the movement of the second moving block 21 on the bidirectional lead screw 20, allowing the second moving block 21 to move along the lead screw 20. Simultaneously, the second moving block 21 moves the limiting plate 5, which in turn limits the cardboard on the conveyor 1, preventing it from tilting or shifting and thus maintaining stability during transport. Furthermore, the first motor 8, bidirectional lead screw 20, limiting rod 22, and second moving block 21 allow for adjustment of the distance between the two limiting plates 5, enabling the limiting of cardboard of different sizes and improving the adaptability of the device.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
