[0008] By adopting the above technical solution, when installing the die-cutting knife, the staff inserts the installation block into the installation slot, and then restricts the installation block through the installation component to achieve the installation of the die-cutting knife. The staff can quickly replace the die-cutting knives of different specifications through the installation component to meet the processing requirements of tapes of different shapes, thereby improving the applicability of the die-cutting machine.

[0009] Optionally, the mounting assembly includes a toggle rod, an ejection spring and a locking block, a movable groove being formed at one end of the mounting block, the locking block slidingly fitting in the movable groove, a toggle groove being formed on the mounting block, the toggle groove being connected to the movable groove, the toggle rod being connected to the locking block and being located in the toggle groove, the ejection spring being arranged in the movable groove and being located between the bottom wall of the movable groove and the locking block, a locking groove being formed on the lifting seat and being plugged in with the locking block, and when the mounting block is installed, one end of the locking block is plugged in and fitted in the locking groove.

[0010] By adopting the above technical solution, when installing the die-cutting knife, the staff inserts the mounting block into the mounting groove. During this process, the staff moves the toggle rod to make the locking block enter the moving groove, and the ejection spring is compressed until the mounting block completely enters the mounting groove. The toggle rod is released, and the locking block moves in the opposite direction under the action of the ejection spring until the toggle rod hits one end of the toggle groove. At this time, the locking block is partially plugged into the locking groove, thereby restricting the mounting block and realizing the installation of the die-cutting knife.

[0011] Optionally, a guiding slope is provided on the locking block, and the thickness of the locking block gradually increases from one end of the locking block to the ejection spring as a reference direction.

[0012] By adopting the above technical solution, when the installation block is inserted into the installation groove, the guiding inclined surface contacts the side of the installation groove, so that the locking block moves and enters the movable groove, omitting the step of the staff moving the toggle lever, making the installation of the die cutting knife more convenient.

[0013] Optionally, the mounting assembly includes a connecting plate, a limiting plate, a hook plate, a tension spring, a fixed shaft and a connecting shaft, the limiting plate is rotatably connected to the lifting seat, the connecting plate is connected to one end of the mounting block and is embedded in the mounting groove, the connecting plate is flush with the surface of the lifting seat, the fixed shaft is connected to the limiting plate, the hook plate is provided with a receiving groove, the receiving groove is a waist-shaped groove, the fixed shaft passes through the receiving groove, the lifting seat is provided with a receiving groove at a position corresponding to the hook plate, the connecting shaft is connected in the receiving groove, the tension spring is connected between the fixed shaft and the hook plate, when the mounting block is locked, the limiting plate covers the connecting plate, the hook plate hooks the connecting shaft, and the tension spring is in a stretched state.

[0014] By adopting the above technical solution, when installing the die-cutting knife, the staff inserts the mounting block into the mounting groove so that the connecting plate is embedded in the mounting groove and flush with the surface of the lifting seat, and then flips the limiting plate so that the limiting plate covers the connecting plate, and the hook plate enters the storage groove, and moves the hook plate until the hook plate hooks the connecting shaft. At this time, the tension spring is in a stretched state, thereby limiting the rotation of the limiting plate and realizing the installation of the die-cutting knife.

[0015] Optionally, a resistance groove is formed on the hook plate, and the resistance groove matches the shape of the connecting shaft. When the mounting block is locked, the resistance groove fits the connecting shaft.

[0016] By adopting the above technical solution, the hook plate hooks the connecting shaft in line contact, and there is a possibility of the hook plate rotating. The staff fits the connecting shaft through the abutment groove to limit the rotation of the hook plate, reducing the possibility of the limiting plate rotating.

[0017] Optionally, the lifting seat is connected to a plurality of limiting columns, and limiting holes are opened on the frame at positions corresponding to the limiting columns, and the lifting seat is slidably fitted on the frame through the limiting columns.

[0018] By adopting the above technical solution, the staff can limit the moving direction of the lifting seat by limiting the sliding fit of the column on the frame, thereby ensuring the working direction of the die-cutting knife and improving the moving stability of the lifting seat.

[0021] Optionally, a plurality of limiting cylinders are connected to the frame, and the limiting cylinders are rubber cylinders. A plurality of supporting springs are connected between the lifting seat and the frame. When the lifting seat moves to the lowest position, the lifting seat contacts the limiting cylinders.

[0022] By adopting the above technical solution, when the lifting seat moves to the lowest point, the gravity inertia of the lifting seat will impact the frame, and with long-term use, the frame may be damaged. The staff uses the elastic force of the support spring to assist in counteracting the gravity inertia of the lifting seat, thereby delaying the lifting seat, and then limits the lowest point of the lifting seat through the limiting cylinder, reducing the possibility of affecting the movement of the lifting seat due to damage to the frame.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 3. When installing the die cutter, the staff inserts the installation block into the installation slot, embeds the connecting plate into the installation slot, and is flush with the surface of the lifting seat, then flips the limiting plate so that the limiting plate covers the connecting plate, and the hook plate enters the storage slot, and moves the hook plate until the hook plate hooks the connecting shaft. At this time, the tension spring is in a stretched state, thereby limiting the rotation of the limiting plate, and the installation of the die cutter is realized;

[0027] 4. When driving the lifting seat to move, the staff starts the driving motor to rotate the rotating disk, driving the eccentric block to rotate. Due to the cooperation between the eccentric block and the driving groove, the eccentric block drives the fixed plate to move during the movement in the driving groove, thereby achieving the effect of driving the lifting seat to move.

[0039] Reference Figure 3 A driving assembly 4 is arranged between the frame 1 and the lifting seat 2, and the driving assembly 4 comprises a driving motor 41, a rotating disk 42, an eccentric block 43 and a fixing plate 44. The driving motor 41 is mounted on the frame 1, the rotating disk 42 is fixedly connected to the output shaft of the driving motor 41, and the eccentric block 43 is fixedly connected to the rotating disk 42. The fixing plate 44 is fixedly connected to the lifting seat 2, and a driving groove 441 is opened on the fixing plate 44, the driving groove 441 is arranged horizontally, and the eccentric block 43 is slidably fitted in the driving groove 441.

[0040] When driving the lifting seat 2 to rise and fall, the staff starts the driving motor 41 to rotate the rotating disk 42, driving the eccentric block 43 to rotate, and the eccentric block 43 cooperates with the driving slot 441 to drive the fixing plate 44 to rise and fall, thereby achieving the effect of driving the lifting seat 2 to rise and fall.

[0041] Reference Figure 1 and Figure 2 In order to reduce the possibility of damage to the frame 1, a plurality of fixed columns are fixedly connected to the bottom end of the frame 1. Four columns are used as an example in this embodiment. The fixed columns are slidably matched with the lifting seat 2. A limiting cylinder 11 is fixedly connected to the fixed columns.

[0042] Reference Figure 1 , Figure 4 and Figure 5 The die cutter 3 is fixedly connected with a mounting block 31, and a mounting groove is provided on the lifting seat 2. The mounting block 31 is plugged into the mounting groove. Both ends of the mounting block 31 in the length direction are provided with mounting components 5, and the mounting components 5 include a toggle rod 51, an ejection spring 52 and a locking block 53. A moving groove 311 and a toggle groove 312 are provided at one end of the mounting block 31. The locking block 53 is slidably fitted in the moving groove 311. A guiding slope 531 is provided at one end of the locking block 53. From one end of the locking block 53 to the bottom wall of the moving groove 311 is a reference direction, and the thickness of the locking block 53 gradually increases. The ejection spring 52 is provided in the moving groove 311 and is located between the bottom wall of the moving groove 311 and the locking block 53. The ejection spring 52 is in a compressed state. One end of the toggle rod 51 is fixedly connected to the locking block 53, and the toggle rod 51 passes through the toggle groove 312. A locking groove is formed at a position of the lifting seat 2 corresponding to the moving groove 311 . When the mounting block 31 is locked, the locking block 53 is partially inserted and fitted in the locking groove.

[0043] The implementation principle of the die-cutting mechanism of a die-cutting machine in Example 1 of the present application is as follows: when installing the die-cutting knife 3, the staff inserts the mounting block 31 into the mounting groove. During this process, the guiding inclined surface 531 contacts the side of the mounting groove, causing the locking block 53 to move into the movable groove 311, and the ejection spring 52 is compressed until the movable groove 311 is aligned with the locking groove. The locking block 53 moves in the opposite direction under the action of the ejection spring 52 until part of the toggle rod 51 contacts one end of the toggle groove 312. At this time, one end of the locking block 53 is inserted into the locking groove, thereby limiting the mounting block 31 and realizing the installation of the die-cutting knife 3.

[0044] The staff can quickly replace the die-cutting knives 3 of different specifications by installing the assembly 5 to cope with the processing of tapes of different shapes, thereby achieving the effect of processing tapes of different shapes by one die-cutting machine and improving the applicability of the die-cutting machine.

[0045] Embodiment 2: The difference between this embodiment and embodiment 1 is that the structure of the mounting component 5 is different.

[0046] Reference Figure 6 , Figure 7 and Figure 8 The mounting assembly 5 includes a connecting plate 54, a limiting plate 55, a hook plate 56, a tension spring 57, a fixed shaft 58 and a connecting shaft 59. The connecting plate 54 is fixedly connected to both ends of the mounting block 31. The connecting plate 54 is embedded in the mounting groove and is flush with the surface of the lifting seat 2. One end of the limiting plate 55 is hinged on the lifting seat 2, and the limiting plate 55 covers the connecting plate 54. The fixed shaft 58 is fixedly connected to the limiting plate 55, and a receiving groove is provided on the hook plate 56. The receiving groove is a waist-shaped groove. The fixed shaft 58 passes through the receiving groove. The hook plate 56 is provided with a resistance groove 561 that matches the shape of the connecting shaft 59.

A receiving groove 22 is provided at the position corresponding to the hook plate 56 on the lifting seat 2, and the connecting shaft 59 is fixedly connected in the receiving groove 22.

[0047] When installing the die-cutting knife 3, the staff will insert the mounting block 31 into the mounting groove, and then flip the limiting plate 55 so that the flip plate covers the connecting plate 54, and the hook plate 56 enters the storage groove 22, and move the hook plate 56 so that the connecting shaft 59 fits the abutment groove 561. At this time, the tension spring 57 is in a stretched state, thereby limiting the rotation of the limiting plate 55, and realizing the installation of the die-cutting knife 3.
