[0002] Corrugated paper is a paper packaging material made of at least one layer of corrugated paper and one or more layers of containerboard. The name of corrugated paper comes from its unique wavy structure, which is similar to the tiles on the roof, hence the name "corrugated". Corrugated board is widely used in the packaging industry because of its durability, lightness, high cost-effectiveness, and good cushioning and compression resistance.

[0003] After the initial processing of corrugated cardboard is completed, it is often necessary to use a corrugated cardboard slitting machine to cut the corrugated cardboard. The current corrugated cardboard slitting machine often uses a setting method of installing multiple cutters on the same cutting roller. This setting method requires that when a cutter on the cutting roller is damaged, the entire cutting roller needs to be removed for repair and replacement, which makes the device downtime too long, greatly affecting the processing efficiency of the corrugated cardboard.

[0004] In view of this, a corrugated board slitting machine is proposed. Utility Model Content

[0025] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. In the absence of conflict, the embodiments in this application and the features in the embodiments can be combined with each other. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 .

[0027] The utility model corrugated cardboard slitting machine comprises a frame 1 and a feeding roller 2 and a discharging roller 3 rotatably mounted on the frame 1, a material guide plate 4 for guiding raw materials is arranged at the discharging roller 3 on the frame 1, a mounting rod 5 is fixedly connected to the frame 1, a plurality of slitting components 6 for cutting raw materials are arranged on the mounting rod 5, the slitting components 6 comprise a bracket 61 and a knife holder 7 rotatably mounted on the bracket 61, a limiting hole 62 is arranged on the bracket 61, a plurality of first spiral grooves 51 are arranged on the mounting rod 5, and a first screw 52 is detachably mounted in the first spiral groove 51.

[0028] It should be noted that the mounting rod 5 is arranged in a rectangular strip shape, and the bracket 61 should be provided with a matching mounting groove, and the upper and lower parts of the mounting groove are provided with a limiting hole 62. There is no need to set a thread in the limiting hole 62, and the first spiral groove 51 should be provided with a thread matching the first screw rod 52, so that when the first screw rod 52 is inserted downward, it only needs to be threadedly connected with the first spiral groove 51, which is more convenient when it is removed. In addition, in addition to being used to fix the longitudinal cutting assembly 6 and the mounting rod 5, the limiting hole 62 and the first spiral groove 51 can also facilitate the positioning of the two during installation.

[0029] In the specific setting, a device can be set on the frame 1 to make the two ends of the mounting rod 5 rise or fall at the same time, such as an electric push rod or a hydraulic cylinder, so that the height of the mounting rod 5 and the multiple longitudinal cutting components 6 fixed on the mounting rod 5 can be adjusted. This setting can adjust the cutting depth of the multiple longitudinal cutting components 6, so that the device can meet more diversified production and processing needs.

[0030] Among them, the guide plate 4 is used to export the corrugated cardboard after cutting on the one hand, and on the other hand, it is also used to support the corrugated cardboard under the longitudinal cutting component 6 to ensure that the corrugated cardboard is in a flat state during cutting. In the specific setting, the part of the guide plate 4 located outside the frame 1 can be set with a small angle slope to facilitate the discharge of the corrugated cardboard. Since the corrugated cardboard may be congested at the discharge port due to the influence of friction, the slope can make the corrugated cardboard easier to discharge under the action of its own gravity. At the same time, a winding roller and related driving components can be set downstream of the discharge roller 3 to optimize the storage of the corrugated cardboard after longitudinal cutting.

[0031] Secondly, the longitudinal cutting assembly 6 also includes a driving motor 63 fixedly mounted on the top of the bracket 61, a driving rod 64 is fixedly mounted on the output end of the driving motor 63, a first bevel gear 65 is fixedly mounted on the bottom of the driving rod 64, and the driving rod 64 is used to drive the tool holder 7 to rotate. The driving motor 63 is arranged on the top of each longitudinal cutting assembly 6. When specifically arranged, the driving rods 64 of multiple longitudinal cutting assemblies 6 can be extended outside the bracket 61 and connected to each other by means of belt connection, etc., to reduce the waste of resources. However, it should be noted that the individual replacement operation of each longitudinal cutting assembly 6 should be avoided as much as possible.

[0032] Furthermore, a protruding rod 68 is detachably mounted on the tool holder 7, and the detachable connection can be of various types. In this embodiment, a connection mode of a screw rod and a threaded groove is adopted, and a rotating rod 67 is fixedly mounted on one end of the protruding rod 68, and the rotating rod 67 is rotatably connected to the bracket 61. One end of the rotating rod 67 is fixedly connected to the protruding rod 68, and the other end of the rotating rod 67 is fixedly mounted with a second bevel gear 66, which is meshed with the first bevel gear 65, and is used to drive the tool holder 7 to rotate when the driving motor 63 is started.

[0033] That is to say, when the driving motor 63 is started, it will drive the driving rod 64 and the first bevel gear 65 to rotate, and then the first bevel gear 65 drives the second bevel gear 66 to rotate, and the second bevel gear 66 will cause the rotating rod 67 and the tool holder 7 to rotate.

[0034] Specifically, a blade 71 is fixedly connected to the knife holder 7, and the blade 71 and the knife holder 7 can be fixedly placed in various ways. The blade 71 is a hollowed-out annular blade 71 available on the market, and the knife holder 7 is a disk with a raised groove 72 in the middle that fits the raised rod 68. The two can be fixed by welding or riveting in various ways, and the fixing methods of the two are prior arts, so they will not be described in detail in the specification.

[0035] Furthermore, the tool holder 7 is provided with a protruding groove 72 whose shape matches the protruding rod 68. Figure 4As shown, the raised portion of the raised rod 68 should be exactly in line with the shape of the raised groove 72, so that the raised rod 68 can drive the tool holder 7 to rotate when rotating, and a second spiral groove 681 is provided at one end of the raised rod 68 that matches the raised groove 72, and a second screw rod 69 is detachably mounted on the second spiral groove 681. A limiting plate 691 for preventing the tool holder 7 from falling off is fixedly mounted at one end of the second screw rod 69.

[0036] It should be noted that the second screw 69 is used to cooperate with the rotating rod 67 to fix the tool holder 7, ensuring that when the rotating rod 67 rotates, the tool holder 7 drives the tool to rotate accordingly and can prevent the tool holder 7 and the protruding rod 68 from falling off, thereby ensuring the safety of the device during use.

[0037] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
