Description

Technical Field

[0001] This utility model relates to the field of mechanical segmentation, and in particular to a slitting mechanism for a digital printing machine. Background Technology

[0002] The slitting mechanism of a digital printing press is a device specifically designed for the later stages of the printing process. Its main function is to cut small finished products or single sheets of predetermined sizes from large-format continuous printed materials, such as cutting printed rolls of paper into printed materials of different sizes. Therefore, the slitting mechanism is extremely important in the printing industry, as it directly affects the quality of the finished product and production efficiency. However, existing digital printing presses cannot precisely control the tension of the rolls, causing the material to be transported unevenly and deformed during the cutting process. This results in uneven lengths of the cut printed materials, making it impossible to guarantee cutting accuracy and reducing work efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a slitting mechanism for a digital printing machine.

[0004] To solve the above-mentioned technical problems, the present invention provides a cutting mechanism for a digital printing machine, including a base plate. Support plates are fixedly connected to both sides of the base plate near its center. A rectangular hole is provided through the center of the support plate. Slide rail grooves are provided on both sides of the rectangular hole. A track slider is provided in the middle of the rectangular hole. The two ends of the track slider are slidably connected to the slide rail grooves on both sides of the rectangular hole. A drive shaft is rotatably connected through the side wall of the track slider. A chain-type conveying cutting mechanism is provided between the two drive shafts.

[0005] Through the above technical solution, the slide rail groove in the bracket plate is slidably connected to the track slider, and the drive shaft is rotatably connected to both sides of the track slider. This allows the track slider to buffer the movement of the drive shaft. The chain conveyor cutting mechanism is located between the two rotating shafts and is fixedly connected to the drive shaft.

[0006] The chain conveyor cutting mechanism includes gears, chains, and mounting plates. The gears are fixedly connected to both ends of the drive shaft. The chains are rotatably connected to the mounting plates. The gears are slidably connected to multiple sets of chains and mounting plates. A mounting groove is provided in the middle of the upper surface of the mounting plate, and a press-type buckle mechanism is provided in the mounting groove.

[0007] Through the above technical solution, the chain conveyor cutting mechanism consists of a series of linked chains and mounting plates. When the two drive shafts rotate, they will drive the chain conveyor cutting mechanism to move, which can cut the printed materials on the conveyor belt at a fixed point. This mechanism can improve the cutting accuracy and work efficiency and is easy to inspect and maintain. The push-type buckle mechanism in the mounting slot can facilitate the installation and removal of the blade.

[0008] The press-type buckle mechanism includes a mounting shaft, which is fixedly connected to the bottom of the mounting groove. Clamps are symmetrically arranged on both sides of the mounting shaft. A support plate is fixedly connected to the middle of the outer diameter of the clamps. A tension spring is fixedly connected to the lower end of the support plate and the bottom of the mounting groove.

[0009] With the above technical solution, clamps are connected to both sides of the mounting shaft in the middle of the mounting slot. When the blade is pressed into the clamp, sufficient clamping force can be provided by the tension spring fixedly connected to the lower end of the support plate to ensure that the connection is stable and reliable. At the same time, the blade can be easily replaced, which is convenient for multiple disassembly and assembly and is not easily damaged. This allows the mechanism to adjust the size of the paper to be cut.

[0011] The above technical solution involves installing a motor protection plate on the outside of the motor and a compression spring on the motor protection plate. The compression spring is fixedly connected to the baffle, which can provide a shock absorption effect when the motor moves. The drive end of the motor is fixedly connected to the rotating shaft, which allows the transmission shaft to rotate through the motor.

[0012] The present invention is further configured such that there are two symmetrically arranged rotating shafts above the base plate, and each end of the two rotating shafts is rotatably connected to a support base, and the support base is fixedly connected to the upper surface of the base plate. A conveyor belt is installed between the two rotating shafts.

[0013] Through the above technical solution, the support base is used to support the drive shaft, and the rotating shaft is mainly used to transmit rotational power to make the conveyor belt move.

[0014] The present invention is further configured such that the upper and lower surfaces of the rectangular hole are fixedly connected to the upper and lower ends of the track slider with helical springs.

[0015] Through the above technical solution, the helical spring enables the track slider to have a buffering effect.

[0016] The present invention is further configured such that the clamp is slidably connected to the bottom of the blade.

[0017] The above technical solution ensures that the blade is securely and stably fixed inside the clamp, while also allowing for easy blade replacement.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. This utility model features a chain conveyor cutting mechanism. The motor drives the drive shaft to rotate, and the chain conveyor cutting mechanism, which is fixedly connected to the drive shaft, rotates together.

This design allows the printed materials to be transported smoothly and without deformation during cutting, greatly improving cutting accuracy and work efficiency, and making it easy to inspect and maintain.

[0020] 2. This utility model provides a press-type buckle mechanism on the mounting plate. The two sides of the mounting shaft in the press-type buckle mechanism are connected to clamps. When the blade is pressed into the clamps, the tension spring fixedly connected to the lower end of the support plate can provide sufficient clamping force to ensure that the connection is stable and reliable. At the same time, the blade can be easily replaced, which is convenient for multiple disassembly and assembly and is not easily damaged.

When the drive shaft 7 rotates, it will drive the chain conveyor cutting mechanism between the two drive shafts 7 to move. The chain conveyor cutting mechanism can cut the printed materials on the conveyor belt 17 at a fixed point. This mechanism can improve the cutting accuracy and work efficiency and is easy to inspect and maintain.
