Description

Technical Field

[0001] This utility model relates to a paper feeding device, and more particularly to a paper feeding mechanism. Background Technology

[0002] Currently, there are two main types of double-sheet stapling equipment purchased and used by printing and packaging plants in China. One type is the inefficient semi-automatic double-sheet feeding mechanism, widely used in small and medium-sized factories. The second type is the fully automatic double-sheet feeding mechanism, which is highly efficient and safe, and is mainly purchased and used by large-scale printing and packaging plants. With the increase in labor costs and the country's growing emphasis on safety, efficient and safe automated equipment is becoming increasingly popular. The replacement of semi-automatic feeding mechanisms with fully automatic double-sheet feeding mechanisms will become a development trend, and it is of great significance to the survival and development of printing and packaging plants. However, compared with semi-automatic double-sheet feeding mechanisms, fully automatic double-sheet machines are a relatively new product, with relatively few manufacturers and varying levels of production quality and technical capabilities. This often leads to various problems for users, the most serious of which are high equipment investment costs and relatively low production capacity.

[0003] like Figure 1 As shown, the existing paper feeding mechanism includes a frame 1, shaft groups 2, paper feeding mechanism 3, and isolation gauge 4; the isolation gauge 4 is located in the middle of the frame 1; there are two sets of shaft groups 2; the two sets of shaft groups 2 are connected to the frame 1; the two sets of shaft groups 2 are coaxially arranged; there are multiple paper feeding mechanisms 3; the multiple paper feeding mechanisms 3 are divided into two groups; the two groups of paper feeding mechanisms 3 are respectively arranged on the two sets of shaft groups 2; the isolation gauge 4 is located above the space between the two sets of shaft groups 2. Figure 2 As shown, the existing paper feeding method includes a conveying process, an interleaving and overlapping process, and a binding process; the conveying process is to convey two side-by-side paperboards to the interleaving and overlapping process; the interleaving and overlapping process is to interleave the two side-by-side paperboards and then overlap the staple tongue of one paperboard with the staple opening of the other paperboard before sending them to the binding process; the binding process is to bind the staple tongue of one paperboard with the staple opening of the other paperboard together.

[0004] Because the existing paper feeding mechanism has two sets of shaft groups 2 coaxially arranged, and the top surfaces of the two sets of paper feeding mechanisms 3 are located in the same plane, the two paperboards can only be placed side by side during the conveying process. It is impossible to achieve interlacing of the two paperboards, let alone overlap of the staple tongue of one paperboard with the staple edge of another. To achieve overlap of the staple tongue of one paperboard with the staple edge of another, an interlacing overlap process is required. In this process, to achieve precise interlacing of the two paperboards, each time they interlac, the two paperboards must be stopped. Simultaneously, the conveying process must also stop conveying the paperboards. After the two paperboards interlaced in the interlacing overlap process, they are continued to be sent to the binding process. At the same time, the conveying process sends two new, side-by-side paperboards to the interlacing overlap process, and so on. This greatly reduces production efficiency. Utility Model Content

[0320] The first technical problem to be solved by this embodiment is to provide a paper feeding mechanism that can feed juxtaposed cardboard to the next process for binding without stopping, which greatly improves production efficiency and creates higher production value for customers per unit time.

[0321] like Figures 3 to 23 As shown,

[0322] To solve the first technical problem mentioned above, this embodiment provides a paper feeding mechanism.

[0323] Includes frame 1, shaft assembly 2, paper feeding mechanism 3, and isolation barrier 4;

[0324] The isolation barrier 4 is located in the middle of the frame 1;

[0325] Shaft assembly 2 has two sets;

[0326] Two sets of shaft assemblies 2 are rotatably connected to the frame 1;

[0327] There are multiple paper feeding mechanisms 3;

[0328] The multiple paper feeding mechanisms are divided into two groups;

[0329] The two sets of paper feeding mechanisms 3 are respectively installed on the two sets of shaft groups 2;

[0330] The two sets of shaft groups 2 are staggered and parallel;

[0331] One set of shaft group 2 is higher than the other set of shaft group 2;

[0332] A stepped stop gauge 6 is installed between the two sets of shaft groups 2;

[0333] The frame 1 is equipped with a side paper alignment guide 5;

[0334] There are two types of paper-aligning guides (5).

[0335] Two paper guides 5 are distributed on the outside of the two sets of paper feeding mechanisms 3;

[0336] The paper guide 5 is equipped with a side push mechanism 8.

[0337] This embodiment employs two sets of shaft groups 2 arranged in parallel and staggered configurations; one set of shaft groups 2 is higher than the other set of shaft groups 2; a stepped guide rail 6 is provided between the two sets of shaft groups 2; the frame 1 is equipped with a side paper alignment guide rail 5; there are two paper alignment guide rails 5; the two paper alignment guide rails 5 are distributed on the outside of the two sets of paper feeding mechanisms 3; and the paper alignment guide rail 5 is equipped with a side pushing mechanism 8. Therefore, the paper feeding mechanism can deliver the juxtaposed cardboard to the next process for binding without stopping, which greatly improves production efficiency and creates higher production value for customers per unit time.

[0338] Various improvements to this embodiment are described in detail below.

[0339] like Figure 3 As shown,

[0340] A positioning stop 7 is provided in the middle of the frame 1.

[0341] This embodiment employs a positioning stop 7 located in the middle of the frame 1, which allows for positioning according to the standard dimensions of the cardboard, thereby improving the forming quality of the carton.

[0345] Alternatively, the two sets of shaft groups 2 can be connected to the frame 1 via the lifting mechanism 9.

[0346] Because this embodiment uses a set of shaft groups 2 on the right side connected to the frame 1 through a lifting mechanism 9, it can not only set the two shaft groups 2 in parallel and staggered manner for efficient conveying and binding of double-sheet cardboard, but also set the two shaft groups 2 coaxially for conveying and binding of single-sheet cardboard.

There are two frame-side wall panels 1-1, which are fixedly connected via the frame-bottom beam 1-2 and the frame-top beam 1-4. There are also two frame-guide rails 1-5, which are fixed parallel to each other on the frame-bottom beam 1-2. The frame-middle wall panel 1-3 is located in the middle of the frame-bottom beam 1-2. The frame-top beam 1-4 is equipped with a rear paper alignment guide 11. The multiple rear paper alignment guides 11 are divided into two groups; the two groups of rear paper alignment guides 11 are distributed on both sides of the isolation guide 4. Therefore, it is beneficial for the isolation guide 4 and the positioning guide 7 to be adjusted and fixedly connected with the frame-top beam 1-4; there are multiple rear paper alignment guides 11; it is beneficial for the side paper alignment guide 5 to be adjusted and fixedly connected with the frame-top beam 1-4; it is beneficial for the front paper alignment guide 11 to be adjusted and fixedly connected with the frame-top beam 1-4; it is beneficial for the shaft group 2 to be rotatably connected with the frame-middle wall plate 1-3; it is beneficial for the lifting mechanism 9 to be connected with the frame-middle wall plate 1-3, and it is beneficial for aligning the rear side of the paperboard.

[0526] The second technical problem to be solved by this embodiment is to provide a paper feeding method that can feed juxtaposed cardboard to the next process for binding without interruption, which greatly improves production efficiency and creates higher production value for customers per unit time.

[0527] like Figure 3 and Figure 24 As shown,

[0528] To address the second technical problem mentioned above, this embodiment provides a paper feeding method.

[0529] It includes a conveying process and a binding process; the binding process is to bind the tab of one piece of cardboard to the staple opening of another piece of cardboard together;

[0530] The conveying process involves first overlapping the two side-by-side cardboard pieces and then conveying them to the binding process;

[0531] The two cardboard pieces are staggered by two sets of shaft groups 2 that are set in parallel and offset.

[0532] The overlap of the two cardboard pieces is achieved by the side-pushing mechanism 8 provided by the paper-aligning guide 5.

[0533] This embodiment employs a conveying process in which two side-by-side cardboard pieces are first overlapped and then conveyed to the binding process. The overlap of the two cardboard pieces is achieved by two sets of shaft groups 2 being staggered and parallel. The overlap of the two cardboard pieces is achieved by the paper guide 5 being equipped with a side-pushing mechanism 8. Therefore, this paper feeding method can convey the side-by-side cardboard pieces to the next process for binding without interruption, greatly improving production efficiency and creating higher production value for customers per unit time.

[0534] Various improvements to this embodiment are described in detail below.

[0535] like Figure 3 and Figure 24 As shown,

[0536] When producing double-packed cartons, the two sets of shaft groups 2 are staggered and set in parallel by adjusting the lifting mechanism 9, and the isolation gauge 4, the step gauge 6, the positioning gauge 7 and the side push mechanism 8 are installed.

[0537] When producing single-piece cartons, the two sets of shaft groups 2 are set coaxially by adjusting the lifting mechanism 9; and the isolation guard 4, step guard 6, positioning guard 7 and side push mechanism 8 are removed.

[0538] This embodiment employs the following technical means: when producing double-layered cartons, the lifting mechanism 9 is adjusted to make the two sets of shaft groups 2 staggered and parallel, and the isolation gauge 4, step gauge 6, positioning gauge 7 and side push mechanism 8 are installed; when producing single-piece cartons, the lifting mechanism 9 is adjusted to make the two sets of shaft groups 2 coaxial, and the isolation gauge 4, step gauge 6, positioning gauge 7 and side push mechanism 8 are removed. Therefore, it can not only produce double-layered cartons, but also single-piece cartons, achieving multi-purpose functionality.

[0539] It should be emphasized here that box-stitching machines can be divided into single-piece box-stitching machines and double-piece box-stitching machines, and further divided into bottom-feeding box-stitching machines and top-feeding box-stitching machines. Although this embodiment only describes in detail the improvement of the bottom-feeding mechanism of the double-piece box-stitching machine, those skilled in the art can, based on this, obtain technical solutions for improving the top-feeding mechanism of the double-piece box-stitching machine without any inventive effort. Of course, improvements to the paper feeding mechanism of the box-gluing machine can also be obtained. All paper feeding mechanisms employing this utility model, including a frame 1, shaft assembly 2, paper feeding mechanism 3, and isolation gauge 4; the isolation gauge 4 is located in the middle of the frame 1; there are two sets of shaft assembly 2; the two sets of shaft assembly 2 are rotatably connected to the frame 1; there are multiple paper feeding mechanisms 3; the multiple paper feeding mechanisms 3 are divided into two groups; the two groups of paper feeding mechanisms 3 are respectively set on the two sets of shaft assembly 2; the two sets of shaft assembly 2 are staggered and parallel; one set of shaft assembly 2 is higher than the other set of shaft assembly 2; a stepped gauge 6 is provided between the two sets of shaft assembly 2; the frame 1 is provided with a side paper alignment gauge 5; there are two paper alignment gauges 5; the two paper alignment gauges 5 are distributed on the outside of the two groups of paper feeding mechanisms 3; the paper alignment gauge 5 is provided with a side pushing mechanism 8. This utility model protects all types of paper feeding machines, including single-piece nailing machines, double-piece nailing machines, bottom-feeding paper nailing machines, top-feeding paper nailing machines, and even gluing machines.
