Description

Technical Field

[0001] This utility model relates to the field of industrial printers, specifically to a pneumatic cutting mechanism and an industrial printer. Background Technology

[0002] A pneumatic cutting device is a machine that uses air pressure energy to drive a cutter for cutting operations. It typically consists of an air source, air circuit system, cutter holder, and cutter. Pneumatic cutting devices are widely used in the cutting and processing of materials such as textiles, leather, rubber, and plastics. Currently, printing and cutting are mainly handled by dedicated cutting machines. Large-scale cutting machines are often designed with roller systems to match the printer, resulting in the printer occupying a significant amount of space when used with the cutting machine. However, printers are usually quite wide and occupy a large amount of space, making the space for placing the cutting machine very limited and easily exceeding the available area. Therefore, most cutting work involves transferring the fabric to a dedicated area before cutting it with a cutting machine, which is quite cumbersome.

[0003] Utility model patent CN220180414U discloses a printer cutting mechanism and a printer with integrated cutting function, including a cutter, a pressure roller, a bracket, and a lifting drive mechanism. The lifting drive mechanism is mounted on the bracket, and the cutter and pressure roller are mounted on the movable end of the lifting drive mechanism. The pressure roller is located inside, outside, or both sides of the cutter. The lower edge of the cutter is lower than or equal to the lower surface of the pressure roller. This printer cutting mechanism and printer with integrated cutting function have the advantages of stable cutting action and integration into a printer. However, because the cutter is suspended in the air and has no support underneath during cutting, it cuts laterally rather than slicing, which can cause defects such as deformation and stretching of the printing medium. Utility Model Content

[0004] In order to improve cutting efficiency, support the cutter during cutting, and avoid defects such as deformation and stretching of the printing medium, the technical solution adopted by this utility model is: a pneumatic cutting mechanism, including a cutter, a cutter holder, a support plate that is snapped onto the printing adsorption platform, and a lifting drive mechanism installed on one side of the printing carriage.

[0005] The cutter is mounted on the cutter holder and is used for rolling cuts of the printing medium;

[0006] The support plate is disposed below the cutter and is used to support the cutter;

[0007] The lifting drive mechanism is connected to the top of the blade holder and is used to roll and press the cutting blade onto the support plate by driving the blade holder.

[0008] Based on the above, in order to perform continuous cutting, the cutter is a disc-shaped cutter, and the outer edge of the disc-shaped cutter is provided with a cutting edge.

[0009] Based on the above, in order to improve cutting stability, the upper surface of the support plate is flush with the printing adsorption platform.

[0010] Based on the above, in order to facilitate replacement and maintenance, the support plate is detachably connected to the printing adsorption platform.

[0011] Based on the above, in order to improve support stability, the width of the support plate is greater than the thickness of the cutter.

[0012] Based on the above, in order to facilitate lifting, the lifting drive mechanism is a telescopic cylinder, and the tool holder is connected to the telescopic end of the telescopic cylinder.

[0013] This embodiment also provides an industrial printer equipped with the aforementioned pneumatic cutting mechanism.

[0014] This utility model has substantial features and advancements compared to existing technologies. Specifically, the pneumatic cutting mechanism provided by this utility model connects the cutter to the printing carriage via a cutter holder and a cylinder, and sets a support plate on one side of the printing adsorption platform to support the cutter blade. Thus, when it is necessary to perform transverse cutting of the printing medium, the high-precision movement of the printing carriage can drive the cutter to perform rolling cutting, thereby achieving support for the cutter blade and ensuring that the printing medium is cut from the top, thereby improving cutting efficiency and avoiding defects such as deformation and stretching of the printing medium.

[0015] Furthermore, by pressing the cutter blade against the support plate during cutting, the printing media can be pressed firmly, eliminating the need for additional paper pressure rollers and simplifying the structure.

[0016] Furthermore, the cutting function is directly integrated into the printer, specifically located on one side of the moving printing carriage. When cutting is required, the cutter drops down to cut the printing medium. As the printing carriage moves, the printing medium is directly cut off, avoiding the problem of introducing a separate cutting mechanism.

[0017] Furthermore, since the cutting motion is combined with the printing carriage and is consistent with the cutting requirements of the printing media, a set of motion drive devices for cutting is saved, thus saving costs. Attached Figure Description
