[0008] The elastic mechanism includes a mounting shell, which is fixedly mounted on the lower end of the adjusting block. A movable block is slidably connected to the inner side of the lower end of the mounting shell. A guide rod is fixedly mounted on the inner side of the mounting shell. One end of the guide rod is slidably connected to the inner side of the movable block. A first spring is sleeved on the outer side of the guide rod. The wheel frame of the indentation wheel is fixedly mounted on the lower end of the movable block. The connecting frame is fixedly mounted on the outer side of the mounting shell.

[0009] The fixing mechanism includes a mounting cavity and a slot. The slot is located on the outside of the blade holder. The upper end of the cutting blade is inserted into the slot inside the blade holder. The mounting cavity is located inside the blade holder. A movable plate is slidably connected to the inside of the mounting cavity. A locking block is fixedly installed on one side of the movable plate. The locking end of the locking block extends movably into the inside of the slot and engages with the cutting blade. A pull rod is fixedly installed on the side of the movable plate away from the locking block. A second spring is sleeved on the outside of the pull rod. A pull block is fixedly installed at the end of the pull rod away from the movable plate, which slides through the inner wall of the mounting cavity.

[0010] As a preferred technical solution, connecting blocks are symmetrically welded to the outer side of the mounting shell, and the connecting blocks are fixedly installed by screws and the lower end of the adjusting block.

[0011] As a preferred technical solution, the upper end of the movable block is provided with a spring groove, and one end of the first spring is located inside the spring groove.

[0012] As a preferred technical solution, the inner side of the mounting shell is symmetrically provided with a first sliding groove, and the upper end of the movable block is slidably connected to the inner side of the first sliding groove of the mounting shell.

[0013] As a preferred technical solution, the inner side of the connecting frame is provided with a connecting hole, and the connecting frame is fixedly installed by screws passing through the connecting hole and the mounting shell.

[0014] As a preferred technical solution, the inner side of the mounting cavity is symmetrically provided with a second sliding groove, and the movable plate and the second sliding groove of the mounting cavity are slidably connected.

[0015] As a preferred technical solution, a locking hole is provided on the inner side of the cutting blade, and the locking end of the locking block engages with the locking hole of the cutting blade.

[0016] As a preferred technical solution, the insertion end of the card block is inclined on the side facing the slot opening, and the slot shape is adapted to the upper part of the cutting blade.

[0017] In summary, the present invention has the following main advantages:

[0018] First, insert the upper end of the cutting blade into the slot of the blade holder. During insertion, the upper end of the cutting blade presses against the inclined surface of the retaining block protruding from the slot, causing the movable plate connected to the retaining block to slide inside the mounting cavity. At the same time, the movable plate presses against the second spring on the outside of the pull rod until the inserting end of the retaining block aligns with the retaining hole on the cutting blade. Then, the second spring returns to its original position and pushes the retaining block connected to the movable plate into the retaining hole. When disassembling, pull the pull rod with the pull handle. This causes the movable plate connected to the pull rod to separate the retaining block from the retaining hole on the cutting blade. Then, the cutting blade can be directly pulled out of the slot of the blade holder, which makes it convenient to quickly disassemble and replace the cutting blade.

[0019] Secondly, since the upper end of the creasing wheel is connected to the movable block, and the movable block slides within the mounting housing, and while the movable block slides relative to the guide rod in the mounting housing, it also compresses the first spring. This allows the creasing wheel at the lower end of the movable block to elastically creasing the corrugated paper. Therefore, the elastic creasing method can reduce the occurrence of cardboard bursting and is suitable for corrugated cardboard of different thicknesses and materials, meeting the needs and application scenarios of different customers.

[0026] refer to Figures 1 to 5 This embodiment describes a high-efficiency automated corrugated paper cutting and creasing device, comprising a linear motor 1, a lifting device 2 fixedly mounted on the moving part of the linear motor 1, a rotating device 3 at the output end of the lifting device 2, an adjusting device 4 fixedly mounted on the rotating shaft of the rotating device 3, adjusting blocks 401 symmetrically arranged at the lower end of the adjusting device 4, a creasing wheel 10 fixedly mounted at the lower end of the adjusting block 401 via an elastic mechanism 5, a connecting frame 6 fixedly mounted on the outer side of the elastic mechanism 5, an electric push rod 7 fixedly mounted on the upper end of the connecting frame 6, a blade holder 8 fixedly mounted through the output end of the electric push rod 7 via the connecting frame 6, and a cutting blade 9 secured to the inner side of the blade holder 8 via a fixing mechanism 16; it should be noted that the two ends of the linear motor 1 in this technical solution are The linear motor 1 in this technical solution, which is installed on the fixed bracket of the creasing device for corrugated paper production disclosed in announcement number CN219055510U, has the same effect as its corresponding front and rear movement control frame. The rotating lifting device 2 in this technical solution has the same effect as its corresponding hydraulic telescopic rod. The rotating device 3 in this technical solution has the same effect as its corresponding rotating adjustment motor. The adjusting device 4 in this technical solution has the same effect as part of the structure in its corresponding distance adjustable pressing assembly. For example, the output end of the drive motor drives the bidirectional lead screw to rotate, so that the two adjusting blocks 401 connected to the outer thread of the bidirectional lead screw slide closer to each other or slide further away from each other.

[0027] The elastic mechanism 5 includes a mounting shell 501, which is fixedly mounted on the lower end of the adjusting block 401. A movable block 502 is slidably connected to the inner side of the lower end of the mounting shell 501. A guide rod 504 is fixedly mounted on the inner side of the mounting shell 501, with one end of the guide rod 504 slidably connected to the inner side of the movable block 502. A first spring 503 is sleeved on the outer side of the guide rod 504. The wheel frame of the creasing wheel 10 is fixedly mounted on the lower end of the movable block 502, and the connecting frame 6 is fixedly mounted on the outer side of the mounting shell 501. When it is necessary to creasing the corrugated paper, the lower end of the adjusting block 401 is creasing under the action of the lifting device 2. The roller 10 can contact the corrugated paper. Since the upper end of the creasing roller 10 is connected to the movable block 502, and the movable block 502 slides within the mounting housing 501, while sliding relative to the guide rod 504 in the mounting housing 501, it also compresses the first spring 503. This allows the creasing roller 10 at the lower end of the movable block 502 to elastically creasing the corrugated paper. Therefore, the elastic creasing method can reduce the occurrence of cardboard bursting. Furthermore, the elastic creasing method is suitable for corrugated cardboard of different thicknesses and materials, which can meet the needs of different customers and application scenarios.

[0028] The fixing mechanism 16 includes a mounting cavity 161 and a slot 167. The slot 167 is located on the outside of the blade holder 8. The upper end of the cutting blade 9 is inserted into the slot 167 of the blade holder 8. The mounting cavity 161 is located inside the blade holder 8. A movable plate 162 is slidably connected to the inner side of the mounting cavity 161. A locking block 166 is fixedly installed on one side of the movable plate 162. The locking end of the locking block 166 extends into the inner side of the slot 167 and engages with the cutting blade 9. A pull rod 164 is fixedly installed on the side of the movable plate 162 away from the locking block 166. A second spring 163 is sleeved on the outside of the pull rod 164. A pull block 165 is fixedly installed on the end of the pull rod 164 away from the movable plate 162, which slides through the inner wall of the mounting cavity 161. When installing the cutting blade 9, the upper end of the cutting blade 9 is inserted along the slot 167 of the blade holder 8. During the insertion process, the upper end of the cutting blade 9... The inclined surface of the locking block 166 extending from the slot 167 is pressed, causing the movable plate 162 connected to the locking block 166 to slide inside the mounting cavity 161. At the same time, the movable plate 162 presses the second spring 163 on the outside of the pull rod 164 until the locking end of the locking block 166 corresponds to the locking hole 15 on the cutting blade 9. Then, the second spring 163 resets and pushes the locking block 166 connected to the movable plate 162 into the locking hole 15. When disassembling, the pull rod 164 is pulled by the pull handle, so that the movable plate 162 connected to the pull rod 164 drives the locking block 166 to separate from the locking hole 15 on the cutting blade 9. Then, the cutting blade 9 can be directly pulled out from the slot 167 of the blade holder 8, which makes it convenient to quickly disassemble and replace the cutting blade 9. When using the indentation function, the cutting blade 9 is in the raised state. Conversely, when the output end of the electric push rod 7 drives the cutting blade 9 of the blade holder 8 to be lowered, it is in the cutting state.

[0029] refer to Figure 3 A connecting block 12 is symmetrically welded to the outer side of the mounting shell 501. The connecting block 12 is fixedly installed by screws and the lower end of the adjusting block 401. The mounting shell 501 can be easily installed below the adjusting block 401 by means of the connecting block 12 in the mounting shell 501.

[0030] refer to Figure 3 The upper end of the movable block 502 is provided with a spring groove 13, and one end of the first spring 503 is located inside the spring groove 13. By providing a spring groove 13 at the upper end of the movable block 502, it is convenient to store the first spring 503 during the compression process.

[0031] refer to Figure 3 The inner side of the mounting shell 501 is symmetrically provided with a first sliding groove 11. The upper end of the movable block 502 is slidably connected to the inner side of the first sliding groove 11 of the mounting shell 501. By providing the first sliding groove 11 on the inner side of the mounting shell 501, the movable block 502 can be limited and slid within the inner side of the mounting shell 501.

[0032] refer to Figure 4 The inner side of the connecting bracket 6 is provided with a connecting hole 14. The connecting bracket 6 is fixedly installed to the mounting shell 501 by screws passing through the connecting hole 14. Through the connecting hole 14 on the inner side of the connecting bracket 6, the connecting bracket 6 can be easily fixed to the outside of the mounting shell 501 by screws.

[0033] refer to Figure 5 The inner side of the mounting cavity 161 is symmetrically provided with a second sliding groove 17. The movable plate 162 and the second sliding groove 17 of the mounting cavity 161 are slidably connected. Through the second sliding groove 17 provided on the inner side of the mounting cavity 161, the movable plate 162 can slide stably on the inner side of the mounting cavity 161.

[0034] refer to Figure 5 The inner side of the cutting blade 9 is provided with a locking hole 15. The locking end of the locking block 166 is engaged with the locking hole 15 of the cutting blade 9. The locking hole 15 provided on the inner side of the cutting blade 9 allows the locking end of the locking block 166 to easily engage and fix the cutting blade 9.

[0035] refer to Figure 5 The insertion end of the card block 166 is inclined on one side facing the slot of the slot 167. The slot shape of the slot 167 is compatible with the upper part of the cutting blade 9. By designing the insertion end of the card block 166 to be inclined towards the slot of the slot 167, the cutting blade 9 can be easily installed.

[0036] Operating principle and advantages: During use, when it is necessary to crease the corrugated paper, under the action of the lifting device 2, the crease wheel 10 at the lower end of the adjusting block 401 can contact the corrugated paper. Since the upper end of the crease wheel 10 is connected to the movable block 502, and the movable block 502 slides in the mounting housing 501, while the movable block 502 slides relative to the guide rod 504 in the mounting housing 501, it also squeezes the first spring 503, so that the crease wheel 10 at the lower end of the movable block 502 can elastically crease the corrugated paper.

[0037] When installing the cutting blade 9, insert the upper end of the cutting blade 9 into the slot 167 of the blade holder 8. During insertion, the upper end of the cutting blade 9 presses against the inclined surface of the locking block 166 protruding from the slot 167, causing the movable plate 162 connected to the locking block 166 to slide inside the mounting cavity 161. At the same time, the movable plate 162 presses against the second spring 163 on the outside of the pull rod 164 until the locking end of the locking block 166 corresponds to the locking hole 15 on the cutting blade 9. Then, the second spring 163 resets and pushes the locking block 166 connected to the movable plate 162 into the locking hole 15. When disassembling, pull the pull rod 164 by pulling the handle, so that the movable plate 162 connected to the pull rod 164 drives the locking block 166 to separate from the locking hole 15 on the cutting blade 9. Then, the cutting blade 9 can be directly pulled out from the slot 167 of the blade holder 8.
