Description

Technical Field

[0001] This utility model relates to the field of cardboard die-cutting machine technology, and more specifically, to a cardboard die-cutting machine that facilitates the replacement of die-cutting blades. Background Technology

[0002] A cardboard die-cutting machine is a type of mechanical equipment specifically designed for die-cutting cardboard. It can cut large cardboard materials into predetermined shapes. In some existing cardboard die-cutting machines, after the cardboard is processed, the operator manually removes the processed cardboard from the placement table and then transfers new cardboard to the placement table. When the number of cardboard is large, the operator's workload is heavy, time-consuming, and labor-intensive.

[0003] To address the aforementioned issues, patent document publication number CN221496195U discloses a cardboard die-cutting machine, comprising a frame and a die-cutting blade body. The die-cutting blade body is located on and connected to the frame, and contacts the cardboard for cutting the cardboard. The machine also includes a feeding box, a driving mechanism, a transmission component, a support plate, and a feeding mechanism. The feeding box is located on and connected to the frame.

[0004] However, in actual use, it still has some drawbacks. For example, through the drive mechanism, the cardboard is transferred to the conveyor through the transmission hole, and then the die-cutting blade body makes the cardboard into the set shape. Through the feeding mechanism, the cardboard is transferred to the set position. There is no need for the staff to manually remove the cut cardboard and place the new cardboard, which reduces the workload of the staff, saves time and effort, and improves production efficiency. After multiple cuts, the die-cutting blade body will wear out, affecting the cutting efficiency. At this time, the die-cutting blade needs to be replaced. However, the die-cutting blade body of this device is installed at the bottom of the connecting plate by bolts. During disassembly and assembly, multiple bolts need to be operated with tools, which is time-consuming and laborious, and the disassembly and assembly efficiency is low. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the embodiments of this utility model provide a cardboard die-cutting machine that facilitates the replacement of die-cutting blades, so as to solve the problem of low disassembly and assembly efficiency caused by the bolt installation of the die-cutting blade body in the prior art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a cardboard die-cutting machine with easy-to-change die-cutting blades, including a frame, with a cylinder fixedly connected to the top of the frame, and the cardboard die-cutting machine with easy-to-change die-cutting blades further includes...

[0007] A connecting plate is fixedly connected to the telescopic end of the cylinder. A die-cutting blade body is installed at the bottom of the connecting plate. A T-shaped slider is fixedly connected to the top of the die-cutting blade body. A T-shaped groove is provided at the bottom of the connecting plate.

[0008] A protrusion is slidably connected to a groove on the side of a connecting plate, and a limiting plate is fixedly connected to one side of the protrusion.

[0009] A sliding column is fixedly connected to the inner cavity of the connecting plate, and a spring is sleeved on the surface of the sliding column.

[0010] The inner wall of the T-shaped groove is slidably connected to the surface of the T-shaped slider, the surface of the limiting plate is slidably connected to the inner wall of the connecting plate, the side of the limiting plate away from the protrusion is in contact with the side of the T-shaped slider, the outer surface of the sliding column is slidably connected to the inside of the limiting plate, and the two ends of the spring are fixedly connected to the top of the connecting plate and the limiting plate, respectively.

[0011] The cardboard die-cutting machine that facilitates die replacement also includes an inspection door assembly, which is located on the side wall of the frame.

[0012] The maintenance door assembly includes a maintenance door body, a handle, a rotating shaft, a gear, a rack, a second T-shaped slider, a second spring, and a locking block. The maintenance door body is hinged to the side wall of the frame. The handle is located on the side of the maintenance door body. The rotating shaft is fixedly connected to one side of the handle. The gear is fixedly connected to the other end of the rotating shaft. The rack meshes with the outer edge of the gear. The second T-shaped slider is fixedly connected to the bottom of the rack. The surface of the second T-shaped slider is slidably connected to the bottom of the inner cavity of the maintenance door body. The two ends of the second spring are fixedly connected to the inner wall of the maintenance door body and the left side of the rack, respectively. The locking block is fixedly connected to the right side of the rack. The surface of the locking block is slidably connected to the side wall of the maintenance door body. The right side of the locking block engages with the locking groove on the side wall of the frame.

[0013] The beneficial effects of the above-mentioned technical solution of this utility model are as follows:

[0014] In the above solution, when the die-cutting blade body is worn, the protrusion is pushed upward, which causes the limiting plate to slide upward along the slide column and compress the spring. After the limiting plate moves away from the T-shaped slide groove, the die-cutting blade body can be pulled backward, causing the T-shaped slider to slide out along the T-shaped slide groove. The die-cutting blade body can be replaced and installed. The replacement process is quick, saves time and effort, improves disassembly and assembly efficiency, and thus ensures the cutting efficiency of the device.

[0015] Turning the handle clockwise causes the gear to rotate clockwise via the shaft, which in turn causes the rack to slide to the left and compress the second spring. The rack then causes the locking block to slide to the left into the inner cavity of the maintenance door body, thus opening the maintenance door body. Since the original device frame has structures on both sides, the maintenance door body and the quick-opening and closing structure facilitate the replacement of the die-cutting blades inside the frame, further improving the efficiency of die-cutting blade disassembly and assembly.
