[0003] In the existing technology, the die-cutting mechanism used to process tear lines is an air curtain die-cutting mechanism. The tear lines are cut by moving the air-controlled cutter up and down, and the workpiece is kept flat by blowing air. However, oil, water and particulate matter in the compressed air can easily be sprayed out through the air nozzle, which will affect the quality of the workpiece. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a die-cutting frame, the top of which is fixedly connected to the bottom of a first air inlet pipe. The die-cutting frame is internally equipped with a cutting blade mechanism, which includes a cylinder, a connecting plate, a trapezoidal slide groove, a trapezoidal mounting groove, a first threaded groove, a trapezoidal slider, a cutting blade holder, a trapezoidal mounting block, a second threaded groove, and bolts. A jetting mechanism is provided on one side of the die-cutting frame, which includes an air pump, a second air inlet pipe, an air nozzle, a fixing ring, a slot, a dustproof frame, a dustproof net, a mounting plate, a fixing block, a spring groove, a connecting spring, and a locking block.

[0006] In a preferred embodiment, the bottom of the die-cutting frame is provided with a movable groove, and the inner wall of the movable groove is fixedly connected to the outer wall of the cylinder. The top air inlet of the cylinder is connected to the inside of the first air inlet pipe, and the bottom of the cylinder is fixedly connected to the top of the connecting plate.

[0007] In a preferred embodiment, a trapezoidal groove is provided at the bottom of the connecting plate, and trapezoidal mounting grooves are provided on both sides of the bottom of the connecting plate.

The inner wall of the trapezoidal groove is movably connected to the outer wall of the trapezoidal slider, and the bottom of the trapezoidal slider is fixedly connected to the top of the cutting blade holder.

[0008] In a preferred embodiment, the top two sides of the cutting blade holder are fixedly connected to the bottom of the trapezoidal mounting block. The trapezoidal mounting block has a second threaded groove inside. The inner wall of the second threaded groove is threadedly connected to the outer wall of the bolt. The outer wall of the bolt is threadedly connected to the inner wall of the first threaded groove.

[0009] In a preferred embodiment, a fixing groove is provided on one side of the die-cutting frame, and the inner wall of the fixing groove is fixedly connected to the outer wall of the air pump. The air inlet on one side of the air pump is fixedly connected to one side of the second air inlet pipe. The air outlet at the bottom of the air pump is fixedly connected to the top of the air nozzle. The outer wall at the bottom of the air nozzle is fixedly connected to the inner wall of the fixing ring.

[0010] In a preferred embodiment, the inner wall of the fixing ring is provided with a slot, and the bottom of the fixing ring is fixedly connected to the top of the dust blocking frame.

[0012] A die-cutting machine incorporating the aforementioned air curtain die-cutting mechanism.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, when gas is sprayed onto the dust-blocking frame, impurities in the gas are blocked by the dust-blocking net. When the dust-blocking net needs to be cleaned regularly, the pressing block squeezes the connecting spring, and at the same time, the pressing block enters the inside of the spring groove, so that the pressing block does not block the top of the fixing ring, so that the mounting plate and the fixing block are released from the locked state, and then the dust-blocking frame can be removed. This facilitates the blocking of impurities in the sprayed gas and reduces the impact of impurities on the workpiece quality.

[0015] 2. In this utility model, a tool is used to remove the bolt, which moves away from the inside of the second thread groove and the first thread groove, allowing the cutting tool holder to be released from the locked state. The cutting tool holder is then pulled out, which in turn drives the trapezoidal slider to move along the inner wall of the trapezoidal groove. At the same time, the trapezoidal mounting block is removed from the inside of the trapezoidal mounting groove, thereby disassembling the cutting tool holder. This facilitates the inspection and replacement of damaged cutting tool holders. Attached Figure Description
