[0002] A rotary printing press is a highly efficient printing device, which is mainly used in large-volume printing industries such as books, newspapers, magazines, and advertisements. During the operation of a rotary printing press, a cutting knife or a serrated knife is arranged on the roller to cut or cut out segment lines on the printed paper. In current technology, the replacement of the cutting knife and the serrated knife on the roller is rather cumbersome, requiring one end of the roller to be separated from the equipment, and then the knife is embedded or set on the roller, which is quite time-consuming. Utility Model Content

[0003] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and utility model name of this application to avoid blurring the purpose of this section, specification abstract and utility model name, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0004] In view of the following technical problems in the prior art: In the current rotary printing machine, when replacing the cutter, the disassembly and assembly process is relatively cumbersome, and the disassembly process of the rotary roller is required.

[0021] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

When describing the embodiments of the present invention, for the sake of convenience, the cross-sectional diagrams showing the device structure will not be partially enlarged according to the general scale, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention.

[0025] Reference Figure 1-4 One embodiment of the utility model provides a rotary cutting mechanism, comprising the following parts:

[0026] The roller 1 is used to equip the tool 3. Specifically, a receiving area 2 is constructed inside the roller 1 and communicated with the outer peripheral side of the roller 1. There are multiple receiving areas 2, and the specific number corresponds to the type of the tool 3.

[0027] The cutter 3 is divided into a cutting cutter and a serrated cutter. The present invention will be described uniformly according to the cutter 3. Different cutters 3 are movably arranged in a plurality of the containing areas 2.

[0028] The number of the adjusting parts 4 corresponds to that of the containing area 2. Specifically, the tool 3 can be extended from the containing area 2 and can also be retracted by the adjusting parts 4.

[0029] Based on this, in the utility model, different types of cutters 3 can be simultaneously transferred to the rotating roller 1. Two types are shown in the figure, namely a cutting knife and a serrated knife, which are used as a reference. During the operation of the equipment, when the required cutter 3 is selected for assembly, the corresponding cutter 3 can be extended into the zone 2 through the corresponding adjustment part 4. Compared with the prior art, there is no need to remove the rotating roller 1 from the equipment, thereby saving a certain amount of time and simplifying a certain process.

[0030] Further, see Figure 3 and Figure 4 The adjusting part 4 includes a spring assembly 401, which is arranged in the containing zone 2. The tool 3 is kept to be subjected to force toward the inner side of the containing zone 2 through the spring assembly 401. The spring assembly 401 can be an elastic metal sheet, one end of which is fixedly clamped to the inner wall of the containing zone 2. In normal state, the tool 3 is pushed back into the containing zone 2 by the elastic force of the other end of the metal sheet. The adjusting part 4 also includes a movable block 402, which is located in the containing zone 2. When the movable block 402 moves, it forms a thrust on the tool 3, and the thrust is toward the outside of the containing zone 2. Therefore, when adjusting the state of the tool 3, it is sufficient to directly adjust the movable block 402.

[0031] Further, see Figure 1-4 The movable block 402 is columnar and remains parallel to the roller 1, and is rotatably arranged on the roller 1. At least one end of the movable block 402 penetrates the outside of the roller 1, so that personnel can adjust it conveniently. The movable block 402 is configured with an outer convex portion 402a on the peripheral side, and the outer convex portion 402a is used to contact the tool 3. Specifically, when the movable block 402 is controlled to rotate within a fixed angle range, the outer convex portion 402a can push the tool 3, thereby achieving an adjustment effect. This structural design makes the adjustment process simple, convenient, and easy to operate.

[0032] Further, see Figure 3 and Figure 4 The tool 3 includes a first section 301 and a second section 302, the first section 301 is in sheet shape, the containing area 2 includes a first area 201 and a second area 202, the first section 301 and the first area 201 are in sliding cooperation, the second section 302, the spring assembly 401 and the movable block 402 are all located in the second area 202, and the second area 202 is close to the inside of the roller 1. This structural design helps to improve the utilization of the internal space of the roller 1, while reducing occupancy and reducing the area that needs to be hollowed out inside the roller 1, thereby maintaining its structural strength.

[0033] Further, see Figure 3 and Figure 4 The second section 302 is in a bent structure. The spring assembly 401 and the movable block 402 act on the second section 302 during operation. The second section 302 is in a bent structure, so that the toughness of the material of the tool 3 itself can be used to form a certain elastic effect at this location. Therefore, during the rotation of the roller 1, the edge of the first section 301 of the tool 3 can be kept in full contact with the paper, that is, the blade of the tool 3 can be kept in full contact with the paper to prevent inadequate cutting.

[0034] Further, see Figure 3 and Figure 4The outer convex portion 402a has a pushing surface 5 and a contact surface 6 for contacting the second section 302. Specifically, the pushing surface 5 is an arc-shaped structure. As shown in the perspective in the figure, when the roller 1 rotates clockwise, the pushing surface 5 can better gradually apply thrust to the second section 302 during the movement through the arc-shaped structure to keep the process smooth. The contact surface 6 is a planar structure. When the outer convex portion 402a rotates a certain angle, the contact surface 6 will contact the second section 302. Through its planar structure, it forms a good contact with the surface of the second section 302, which helps to maintain a stable effect during the contact process. At this time, the tool 3 is fully extended to ensure a stable effect during the working process.

[0035] It will be appreciated that in the development of any actual implementation, as in any engineering or design project, numerous implementation-specific decisions may be made. Such a development effort may be complex and time-consuming, but will be a routine task of design, fabrication, and production for those of ordinary skill having the benefit of this disclosure without undue experimentation.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
