Description

Technical Field

[0001] This utility model relates to the field of high-speed rotary inkjet printing machine technology, and in particular to a cutting blade structure for a high-speed rotary inkjet printing machine. Background Technology

[0002] High-speed rotary inkjet printers are efficient continuous printing equipment suitable for high-volume printing of newspapers, packaging, books, and other publications. They employ a rotary operation, using a high-speed printhead array to achieve non-contact inkjet printing. Combined with a roll-to-roll conveyor system, printing speeds can reach hundreds of meters per minute, offering both high throughput and flexibility. The cutting blade structure is a key component, used to cut continuously printed rolls into specified sizes. It typically uses a disc-type blade, consisting of an upper and lower blade, with a precision synchronization mechanism ensuring cutting accuracy. The cutting length of the blade can be adjusted according to requirements, and it is equipped with automatic sharpening and pressure adjustment devices to guarantee cutting quality under long-term high-speed operation. It is widely adaptable to paper or film materials of different thicknesses.

[0003] Existing cutting technologies often employ a single disc-type blade combination, whose clamping and limiting mechanism design has significant flaws. For printed materials with multi-layered characteristics, such as newspapers and books, the lack of a targeted clamping and limiting device makes it difficult to dynamically adjust the clamping force according to the material thickness and the number of layers. Furthermore, the existing blade structure has poor synchronization between the clamping components and the cutting blade, failing to form a stable clamping constraint at the moment of cutting. This not only leads to burrs and rough edges on the cut edges but also causes cutting size errors due to paper misalignment. Frequent manual adjustments not only reduce production efficiency but also amplify cutting defects due to operational errors, seriously affecting the continuity of subsequent binding, stacking, and other processes.

[0004] Therefore, it is necessary to invent a cutting blade structure for a high-speed rotary inkjet printer to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a cutting blade structure for a high-speed rotary inkjet printer, in order to solve the problems mentioned in the background art. The cutting blades in the prior art mostly adopt a single disc-type blade combination, and their clamping and limiting mechanism design has obvious defects. For printed materials with multi-layered characteristics such as newspapers and books, due to the lack of a targeted clamping and limiting device, it is difficult to dynamically adjust the clamping force according to the material thickness and the number of stacked layers. At the same time, the existing blade structure has poor synchronization between the clamping component and the cutting blade, and cannot form a stable clamping constraint at the moment of cutting. This not only makes the cutting edge prone to burrs and rough edges, but also causes cutting size errors due to paper misalignment. Frequent manual adjustments not only reduce production efficiency, but also amplify cutting defects due to operational errors, seriously affecting the continuity of subsequent binding, stacking and other processes.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a cutting blade structure for a high-speed rotary inkjet printer, including a blade holder, a blade body at the bottom of the blade holder, L-shaped plates symmetrically arranged on both sides of the blade holder, a third mounting hole on the side of the L-shaped plate near the blade holder, and the L-shaped plate being fixedly connected to the side of the blade holder by bolts.

[0007] The bottom end of the L-shaped plate is provided with a guide rod, which is slidably connected to the inner side of the L-shaped plate. A pressure plate is fixedly connected to the bottom end of the guide rod, and a rubber pad is provided at the bottom end of the pressure plate. A spring is provided on the outer side of the guide rod.

[0008] As a preferred embodiment, a limiting ring is fixedly connected to the top end of the guide rod, the limiting ring is disposed at the top end of the L-shaped plate, and the spring is disposed between the pressure plate and the L-shaped plate.

[0009] As a preferred embodiment, the bottom end of the tool holder is provided with a slot, which corresponds to the middle blade body. The side of the tool holder is provided with a first mounting hole, and the middle blade body is fixedly connected to the inside of the slot by bolts.

[0010] As a preferred embodiment, the top of the tool holder is provided with a fixing plate, and the fixing plate has second mounting holes on both sides. An electric telescopic rod is fixedly connected to the top of the fixing plate.

[0011] As a preferred embodiment, the output end of the electric telescopic rod is fixedly connected to a fixing frame through the fixing plate, and a limit groove is provided at the bottom end of the fixing frame.

[0012] As a preferred embodiment, a slider is fixedly connected to the top of the tool holder, and limit blocks are fixedly connected to both sides of the slider, with the slider and limit blocks corresponding to the limit groove.

[0013] The technical effects and advantages of this utility model are as follows:

A pressure plate is fixedly connected to the bottom end of the guide rod. A rubber pad is fixedly connected to the bottom end of the pressure plate. A spring is provided on the outer side of the guide rod. When the blade holder moves downward to perform cutting work, the pressure plate can effectively press the object to be cut, thereby facilitating the subsequent downward movement of the middle blade body for cutting work and effectively improving the stability of cutting.

A pressure plate 34 is fixedly connected to the bottom end of the guide rod 35. A rubber pad 341 is fixedly connected to the bottom end of the pressure plate 34. A spring 33 is provided on the outer side of the guide rod 35. When the blade holder 1 moves downward to perform cutting work, the pressure plate 34 can effectively press the object to be cut, thereby facilitating the subsequent downward movement of the middle blade body 11 for cutting work and effectively improving the stability of cutting.

[0028] Please see the appendix Figure 4 The top end of the guide rod 35 is fixedly connected to a limiting ring 32, which is located at the top end of the L-shaped plate 3. The spring 33 is located between the pressure plate 34 and the L-shaped plate 3.

[0029] Specifically, by setting a limiting ring 32, which is fixedly connected to the guide rod 35, the limiting ring 32 can effectively limit the movement of the guide rod 35. The spring 33 is set between the L-shaped plate 3 and the pressure plate 34.
