Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of box-making machines, and in particular relates to a paper-folding structure for a box-making machine. Background Technology
[0002] A carton stapler is one of the finishing processes for cardboard boxes. Its principle is the same as that of a regular stapler, except that the carton stapler uses a toothed plate as a backing plate. It is specifically designed for sealing cardboard boxes. This series of products has the advantages of being lightweight, easy to operate, wear-resistant, producing a flat and secure seal, and reducing labor intensity and improving work efficiency. It is widely used for sealing various cardboard boxes and calcium plastic boxes that need to be loaded with heavy items or are not easy to seal with adhesive tape. When binding flat paper into a three-dimensional box, the flat paper needs to be folded beforehand, so a paper folding device is required.
[0003] When folding paper, origami devices typically press down on specific locations on the paper to create creases. The paper is then flipped over starting from these creases, and the two ends are stacked together for binding. In actual binding, different shaped boxes need to be folded, resulting in varying crease positions on the paper surface. Therefore, the position of the pressing component needs adjustment. In existing, space-saving origami devices, the pressing component is usually located on either side of a column above the base plate. However, the limited space within the column restricts its adjustment range, making it impractical.
[0004] Therefore, we propose a paper-folding structure for a nailing machine to solve the above problems. Utility Model Content
[0005] The purpose of this invention is to solve the problem in the prior art where insufficient space affects the adjustment range of paper folding, and to propose a paper folding structure for a nailing machine.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A paper-folding structure for a nailing machine includes a base plate, mounting grooves on both sides of the top surface of the base plate, a rotating roller rotatably mounted inside one side of the mounting groove, folding frames slidingly mounted on both sides of the middle of the top surface of the base plate, and a folding moving assembly for driving the two folding frames to move synchronously in opposite directions in the middle of the base plate.
[0008] A mounting frame is fixed above the rotating roller. A column is provided at the center of the bottom surface of the mounting frame, which moves up and down. A hollow first mounting cylinder and a second mounting cylinder are respectively slidably provided on both sides of the column, and the second mounting cylinder is slidably housed inside the first mounting cylinder.
[0009] A first toothed plate is fixedly connected inside the first mounting cylinder, and a second toothed plate is fixedly connected inside the second mounting cylinder. The column is equipped with a drive assembly that drives the first toothed plate and the second toothed plate to move synchronously in opposite directions. Pressure rollers are rotatably connected to the ends of the first mounting cylinder and the second mounting cylinder that are far apart from each other, and the two pressure rollers are at the same height.
[0010] Preferably, the pressure roller is tilted, and the tilted upper end of the pressure roller faces the column.
[0011] Preferably, the pressure roller is located directly above the rotating roller.
[0012] Preferably, the folding and moving assembly includes a double-ended lead screw rotatably disposed inside the base plate, and the bottoms of the two folding frames are respectively threaded onto both ends of the double-ended lead screw.
[0013] Preferably, the first toothed plate and the second toothed plate face each other, the driving assembly includes two gears rotatably disposed on the inner side of the column, and the two gears mesh with the first toothed plate and the second toothed plate respectively. The side walls of the first mounting cylinder and the second mounting cylinder are provided with moving grooves for the gears to pass through and slide, and the outer side of the column is provided with a synchronization assembly for driving the two gears to rotate synchronously.
[0014] Preferably, the two gears are of the same size, and the tooth pitch of the first tooth plate and the second tooth plate is the same.
[0015] In summary, the technical effects and advantages of this utility model are as follows: The paper-folding structure of this nailing machine, through the drive component and the first and second toothed plates, enables the first and second mounting cylinders to move in opposite directions. This allows the second mounting cylinder to slide and be housed inside the first mounting cylinder when they are close together, and to detach from the first mounting cylinder when they are far apart. This results in high space utilization and a large adjustment range. Compared with existing devices, it avoids the problem of insufficient space leading to a small adjustment range for paper folding, thus improving the practicality of the device.

[0021] 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.
[0022] Reference Figure 1-3 A paper-folding structure for a nailing machine includes a base plate 1, mounting grooves 2 on both sides of the top surface of the base plate 1, a rotating roller 3 rotatably mounted on one side inside the mounting groove 2, folding frames 4 slidingly mounted on both sides of the middle of the top surface of the base plate 1, and a folding moving assembly that drives the two folding frames 4 to move synchronously in opposite directions in the middle of the base plate 1.
[0023] A mounting frame 5 is fixedly installed above the rotating roller 3. A column 6 is installed on the middle of the bottom surface of the mounting frame 5, which moves up and down. A cylinder for driving the column 6 to move up and down should be fixedly installed on the top of the mounting frame 5. Since the cylinder is existing technology, it will not be described in detail. A hollow first mounting cylinder 7 and a second mounting cylinder 8 are respectively slidably installed on both sides of the column 6, and the second mounting cylinder 8 is slidably housed inside the first mounting cylinder 7.
[0024] The first mounting cylinder 7 is fixedly connected to the first toothed plate 9, and the second mounting cylinder 8 is fixedly connected to the second toothed plate 10. The column 6 is provided with a drive assembly that drives the first toothed plate 9 and the second toothed plate 10 to move synchronously in opposite directions. The ends of the first mounting cylinder 7 and the second mounting cylinder 8 that are far apart from each other are rotatably connected to pressure rollers 11, and the two pressure rollers 11 are at the same height.
[0025] Reference Figure 1 It should be noted that in the folding structure of this box-stitching machine, the top surface of the base plate 1 should be equipped with a transmission belt assembly for driving the cardboard movement. Since transmission belt assemblies are quite common in the box-stitching machine industry, they will not be elaborated upon further. During folding, the cardboard first passes through the pressure roller 11 in conjunction with the rotating roller 3 to press out the folding lines, and then the two sides of the cardboard are folded together with the folding frame 4. The above folding process is quite common and will not be described in detail.
[0026] Reference Figure 1-3 In this cardboard stapling machine's folding structure, when the cardboard size changes, necessitating a change in folding position, the drive assembly drives the first toothed plate 9 and the second toothed plate 10 to move synchronously in opposite directions. This achieves synchronous opposite movement of the first mounting cylinder 7 and the second mounting cylinder 8, allowing the second mounting cylinder 8 to slide and retract into the first mounting cylinder 7. Figure 4As shown. The first mounting cylinder 7 and the second mounting cylinder 8 can also be separated from each other, thereby realizing the position adjustment of the pressure roller 11. After completion, the two folding frames 4 are driven to move synchronously in opposite directions by the folding moving component, thereby realizing the position adjustment of the folding frame 4, that is, realizing the paper folding adjustment.
[0027] Reference Figure 1-3 Due to the influence of the cardboard length, in order to avoid interference from the pressure roller 11 during the cardboard folding process, the pressure roller 11 is tilted, and the tilted upper end of the pressure roller 11 faces the column 6.
[0028] The pressure roller 11 is located directly above the rotating roller 3, and the bottom of the pressure roller 11 is lower than the bottom of the column 6, the bottom of the first mounting cylinder 7, and the bottom of the second mounting cylinder 8, so that the pressure roller 11 works with the rotating roller 3 to press the fold line of the cardboard.
[0029] The folding and moving assembly includes a double-ended lead screw 12 rotatably disposed inside the base plate 1, and the bottoms of the two folding frames 4 are respectively threaded onto both ends of the double-ended lead screw 12. By rotating the double-ended lead screw 12, the two folding frames 4 can be adjusted to move synchronously in opposite directions. The threads at both ends of the double-ended lead screw 12 are equidistant and in opposite directions.
[0030] Reference Figure 3-4 The first toothed plate 9 and the second toothed plate 10 face each other. The drive assembly includes two gears 13 rotatably mounted on the inner side of the column 6, and the two gears 13 mesh with the first toothed plate 9 and the second toothed plate 10 respectively. The side walls of the first mounting cylinder 7 and the second mounting cylinder 8 are provided with moving grooves 14 for the gears 13 to pass through and slide. The outer side of the column 6 is provided with a synchronization assembly 15 for driving the two gears 13 to rotate synchronously. The synchronization assembly 15 is prior art and may include a motor responsible for driving the rotation of the gears 13, and an auxiliary sprocket and chain responsible for synchronizing the rotation of the two gears 13. The above-mentioned synchronization assembly 15 is quite common and will not be described in detail. This drive assembly drives the two gears 13 to rotate synchronously through the synchronization assembly 15, thereby cooperating with the first toothed plate 9 and the second toothed plate 10 to realize the reverse sliding of the first mounting cylinder 7 and the second mounting cylinder 8.
[0031] Both gears 13 are of the same size, and the tooth pitch of the first tooth plate 9 and the second tooth plate 10 is the same, thereby ensuring that the first mounting cylinder 7 and the second mounting cylinder 8 move the same distance. It should be noted that, to avoid collision between the second mounting cylinder 8 and the first tooth plate 9 when the second mounting cylinder 8 is housed inside the first mounting cylinder 7, the first tooth plate 9 and the corresponding meshing gear 13 are located between the first mounting cylinder 7 and the second mounting cylinder 8, while the second tooth plate 10 and the corresponding meshing gear 13 are located inside the second mounting cylinder 8.
[0032] 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.
