Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting machines, in particular to a device for preventing a blade of a die-cutting machine from falling off. Background Art

[0002] The die-cutting machine is a device used for die-cutting materials. Its main function is to perform cutting, creasing, hot stamping and other processing on various materials to meet the needs of product manufacturing. The die of the die-cutting machine has a product slot in the mold, and the cutting knife is set outside the product slot. The cutting knife's blade faces upward and is higher than the mold surface. Place the product to be cut in the mold and use the cutting board to apply pressure to the cutting knife. The cutting knife contacts the product and cuts off the excess part of the product.

[0003] According to a disclosed device for conveniently disassembling a knife plate of a die-cutting machine, the device comprises an operating table, a horizontal lower knife plate is arranged on the operating table, a die-cutting plate is lifted and lowered directly above the lower knife plate, a lifting device for driving the die-cutting plate to lift and lower is arranged on the operating table, a horizontal upper knife plate corresponding to the position of the lower knife plate is arranged between the die-cutting plate and the lower knife plate, the upper knife plate is detachably connected to the die-cutting plate, and a fixing component is arranged between the upper knife plate and the die-cutting plate.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that the fixing or separation of the upper blade plate and the die-cutting plate is facilitated by the fixing component, thereby facilitating the installation and disassembly of the upper blade plate, and the installation and disassembly of the lower blade plate is facilitated by bolts. However, it is not possible to completely prevent the blade from falling off during the die-cutting process, causing quality accidents. The blade will be clamped in the product, causing the blade to be pulled out when the die-cutting mold moves, affecting the die-cutting mold from continuing to complete the work. The die-cutting mold needs to be taken out and the blade needs to be readjusted, which reduces work efficiency. Utility Model Content
