[0031] A limiting assembly is arranged on the base 2, and a guide assembly is arranged between the lifting plate 5 and the vertical plate 4.

[0032] Referring to Figure 2 Specifically, the longitudinal section of the bottom of the electric heating block 8 is in V shape.

[0033] With reference to Figure 6 , specifically: the die cutting platform 3 is provided with a die cutting slot 10 matched with the die cutting knife 9.

[0034] With reference to Figures 2-3 , Figure 5 , specifically: the driving assembly comprises a bracket 11 fixedly installed on the back side of the vertical plate 4, one side of the bracket 11 is fixedly installed with a motor 12, the output end of the motor 12 is fixedly installed with a driving gear 13, the vertical plate 4 is rotatably installed with a transmission shaft 14, one end of the transmission shaft 14 is fixedly installed with a driven gear 15, the driven gear 15 is meshedly connected with the driving gear 13, the other end of the transmission shaft 14 is fixedly installed with a rotating block 16, and the rotating block 16 is rotatably installed with a connecting rod 17 between the lifting plate 5;

[0035] The die cutting platform 3 can be moved to the required position by sliding the base 2 on the T-shaped slide rail, the operator places the packaging board to be die cut on the die cutting platform 3, the driving assembly starts to work, the motor 12 drives the driven gear 15 to rotate through the driving gear 13, and then drives the transmission shaft 14 and the rotating block 16 at the end thereof to rotate, the rotating block 16 drives the lifting plate 5 to move up and down along the guide assembly through the connecting rod 17, the mounting plate 6 is lowered, and the die cutting knife 9 suspended below is synchronously pressed down, at this time, the electric heating block 8 which has been pre-energized and reaches the set temperature uniformly heats the die cutting knife 9 wrapped outside to the ideal state, the die cutting knife 9 descending first contacts the board under the continuous pressure, and the sharp blade with temperature rapidly cuts into the material.

[0036] With reference to Figures 3-4 , specifically: the guide assembly comprises a guide rail 18 fixedly installed on the surface of the vertical plate 4, the guide rail 18 is slidably installed with a sliding block 19, and the sliding block 19 is fixedly connected with the lifting plate 5.

[0037] With reference to Figure 2 , specifically: the electric heating block 8 and the connecting plate 7 are fixedly installed with a heat insulation block 20 therebetween, a plurality of connecting holes 21 are formed in the connecting plate 7, the die cutting knife 9 is provided with a long screw 22 on one side, one end of the long screw 22 penetrates through the connecting hole 21 and is connected with a nut 23.

[0038] With reference to Figure 1 , Figure 4 , Figure 6Specifically: a T-shaped track 24 is fixedly installed on the upper surface of the base plate 1, a T-shaped groove 25 is opened on the lower surface of the base 2, and fixing blocks 26 are fixedly installed on both sides of the base 2. Locking bolts 27 are rotatably installed on the fixing blocks 26. One end of the locking bolts 27 abuts against the upper surface of the T-shaped track 24. A brush 28 is fixedly installed on one side of the fixing block 26. Tightening the locking bolts 27 facilitates the fixation of the position of the die-cutting platform 3. When the base 2 moves, it drives the brush 28 to clean the T-shaped track 24.

[0039] Reference Figure 3 , Figure 6 Specifically: guide posts 29 are fixedly installed at the four corners of the upper surface of the base 2; guide grooves 30 matching the guide posts 29 are provided inside the die-cutting platform 3; guide sleeves 31 are fixedly installed at the bottom of the guide grooves 30; and springs 32 are fixedly installed between the guide sleeves 31 and the guide posts 29.

[0040] Under pressure, the die-cutting platform 3 generates elastic displacement, and the spring 32 is compressed, which cooperates with the downward movement of the die-cutting blade 9 to ensure the thoroughness of the cut, while buffering the impact and protecting the die-cutting blade 9. The cutting edge of the die-cutting blade 9 is finally precisely embedded in the corresponding die-cutting groove 10 on the die-cutting platform 3 to complete a complete die-cutting operation.

[0041] After die-cutting is completed, the drive component moves in the opposite direction, the lifting plate 5 drives the cutter component to rise and reset, and the die-cutting platform 3 also returns to its initial position under the action of the restoring force of the spring 32. The operator can then take out the die-cut product and carry out the next operation.

[0042] Working principle: The electric heating block 8 is directly encapsulated inside the die-cutting blade 9 and is in close contact with the cutting edge of the die-cutting blade 9. When heating is required, the current passes directly through the electric heating block 8, and the heat energy generated is transferred directly to the encapsulated die-cutting blade 9 through heat conduction with almost no loss. This point-to-point direct heating method ensures that the generated heat is used to maximize the temperature of the die-cutting blade 9, so that the die-cutting blade 9 can quickly and stably reach and maintain the optimal cutting temperature. At the same time, since the heat is uniformly conducted from the inside of the die-cutting blade 9 to the outside, rather than being unstablely swept from a point or side, the temperature uniformity along the entire cutting edge length is effectively guaranteed.

[0043] The die-cutting platform 3 can be moved to the desired position by sliding the base 2 on the T-shaped slide rail, and then the locking bolt 27 is twisted to fix the position of the die-cuting platform 3. The operator places the packaging board to be die-cut on the die-cutting platform 3, and the driving assembly starts to work. The motor 12 drives the driven gear 15 to rotate through the driving gear 13, and then drives the rotating block 16 at the end of the transmission shaft 14 to rotate. The rotating block 16 drives the lifting plate 5 to move up and down along the guide assembly through the connecting rod 17, and the mounting plate 6 is lowered, driving the die-cutting knife 9 suspended below to be pressed down synchronously. At this time, the electric heating block 8 has been preheated and reaches the set temperature, and the die-cutting knife 9 wrapped outside is uniformly heated to the ideal state. The descending die-cutting knife 9 first contacts the board under the continuous pressure, and the sharp and temperature blade quickly cuts into the material.

[0044] The die-cutting platform 3 is elastically displaced under the action of the pressure, the spring 32 is compressed, and the downward movement of the die-cutting knife 9 is matched to ensure the completeness of the cutting and buffer the impact, and the die-cutting knife 9 is protected. The blade of the die-cutting knife 9 is finally accurately embedded in the corresponding die-cutting groove 10 on the die-cutting platform 3, and a complete die-cutting operation is completed.

[0045] After the die-cutting is completed, the driving assembly moves reversely, the lifting plate 5 drives the die-cutting knife assembly to lift and reset, and the die-cutting platform 3 also returns to the initial position under the action of the spring 32 recovering the elasticity. The operator can take out the die-cutting product and perform the next operation.

[0046] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
