[0025] Both sides of die cutting assembly 1 are provided with guide 13, and the structure of guide 13 is as shown in Figure 4As shown in the figure, it includes a guide rail and a sliding block. The guide rail is fixed on the inner side wall of the rack 4 by bolts, and the sliding block is fixed on the outer side wall of the die cutting assembly 1 by bolts. The sliding block and the guide rail are in rolling contact through the ball. The sliding positioning module 14 is embedded in the guide 13, which includes a positioning pin and a limiting groove. The positioning pin is connected with the sliding block through a spring, and the limiting groove is opened on the side wall of the guide rail. The positioning pin is embedded in the limiting groove under the action of the spring, so as to realize the accurate positioning of the die cutting assembly 1 in the vertical direction.

When the die cutting tool 5 contacts with the buffer material, the resistance value of the pressure sensitive resistor changes with the change of pressure. The controller calculates the pressure distribution of the die cutting tool 5 according to the resistance value change of the pressure sensitive resistor, and transmits the data to the display screen for display. The controller has a built-in algorithm module, which can adjust the rotating speed and output power of the motor 9 in real time according to the feedback data of the pressure distribution detection module 15, so as to optimize the energy consumption and efficiency in the die cutting process.

The thickness of the shock pad 17 is 10mm to 20mm, and the surface of the shock pad 17 is provided with a plurality of semispherical protrusions, which can effectively improve the impact resistance of the shock pad 17. In the process of equipment operation, the shock pad 17 can absorb vibration energy, reduce the noise generated during equipment operation, and prolong the service life of the equipment.

[0029] The working principle of the utility model is as follows: when needing to die cut the computer buffer material, first, set the die cutting parameters through the operation panel, including cutting depth, cutting speed, etc. Then, the motor 9 is started and drives the die cutting assembly 1 to move up and down reciprocatingly through the transmission mechanism 2. The die cutting tool 5 contacts the buffer material in the downward movement process, at which time the pressure distribution detection module 15 will produce corresponding resistance value changes according to the change of the contact pressure. The controller receives the signal of the pressure sensitive resistor and calculates the pressure distribution of the die cutting tool 5, if the pressure distribution is uneven, the controller will adjust the rotating speed and output power of the motor 9 to optimize the cutting effect. At the same time, the operator can adjust the height of the pressure adjusting plate 7 by rotating the hand wheel of the adjusting screw rod 8, so as to change the compression amount of the elastic supporting column 16, further optimizing the pressure of the die cutting tool 5. The design of the guide 13 and the sliding positioning module 14 ensures the stability of the die cutting assembly 1 in the movement process, avoiding the cutting quality problem caused by the position deviation. The shock pad 17 plays a role in shock absorption and noise reduction in the whole running process, improving the running stability and service life of the equipment.

[0030] The above embodiments describe the structure, the connection relationship between parts and the working principle of the utility model in detail, which ensures that the technical personnel in the art can implement the technical scheme according to the content of the specification.

[0031] In order to better enable the relevant personnel in the technical field to fully understand and implement the utility model, the specific implementation principle of the utility model is supplemented in the following in combination with a specific application scene.

[0032] In the actual operation process, first, the computer buffer material to be die cut is placed on the workbench of the rack 4, and the die cutting parameters are set through the operation panel of the intelligent control unit 3, including the cutting depth, the cutting speed and the pressure range of the die cutting tool 5. Then, start the equipment, the motor 9 starts to run, the output shaft transmits power to the gear set 11 through the synchronous belt 10, and the gear set 11 drives the die cutting tool 5 to move up and down reciprocatingly through the shaft coupling. In this process, the power transmission module of the transmission mechanism 2 ensures the stable operation of the die cutting tool 5, and the tensioning wheel 12 adjusts the tension of the synchronous belt 10 to avoid the occurrence of the slipping phenomenon.

[0033] When the die cutter 5 moves downward and contacts the cushioning material, the pressure-sensitive resistors in the pressure distribution detection module 15 will produce a resistance value change according to the change of contact pressure. After the controller receives these signals, it calculates the pressure distribution of the die cutter 5 through the built-in algorithm and transmits the data to the display screen for real-time display. If uneven pressure distribution is detected, the controller will automatically adjust the speed and output power of the motor 9 to optimize the cutting effect. For example, when cutting thicker cushioning materials, the controller will increase the output power of the motor 9 to increase the downward pressure of the die cutter 5; while cutting thinner materials, it will reduce the output power to avoid excessive cutting.

[0034] At the same time, the operator can rotate the handwheel of the adjusting screw 8 according to the actual needs to adjust the height of the pressure adjusting plate 7. When the adjusting screw 8 rotates, the part that penetrates the frame 4 drives the pressure adjusting plate 7 to move up and down, thereby changing the compression amount of the elastic support column 16. Since the elastic support column 16 is composed of an outer cylinder and an inner rod, and the inner rod is nested inside the outer cylinder and connected by a spring, the change of its compression amount can accurately adjust the pressure of the die cutter 5. This design enables the die cutter 5 to maintain stable cutting effect on materials of different thicknesses, while avoiding cutting quality problems caused by excessive or insufficient pressure.

[0035] During the movement of the die cutting assembly 1, the guide 13 and the sliding positioning module 14 play a key role. The guide rail is fixed to the inner side wall of the frame 4 by bolts, and the sliding block is fixed to the outer side wall of the die cutting assembly 1, and the two are in rolling contact through balls, effectively reducing friction. The positioning pin in the sliding positioning module 14 is embedded in the limiting groove of the guide rail side wall under the action of the spring, thereby achieving precise positioning of the die cutting assembly 1 in the vertical direction. This structural design not only improves the movement stability of the die cutting assembly 1, but also avoids cutting errors caused by position deviation.

[0036] In addition, the shock pad 17 at the bottom of the frame 4 plays an important role in the entire operation process. The shock pad 17 is made of rubber material, and its surface is provided with a plurality of semispherical protrusions, which can effectively improve the impact resistance of the shock pad 17. When the device is running, the shock pad 17 absorbs vibration energy, reduces noise generated during device operation, and reduces the impact of vibration on cutting accuracy, thereby prolonging the service life of the device.

[0037] Through the combination of the above steps and principles, the intelligent die cutting operation of the computer buffer material is realized. The cooperation of the pressure distribution detection module 15 and the intelligent control unit 3 enables the pressure distribution in the die cutting process to be monitored and adjusted in real time, thereby significantly improving the cutting precision and efficiency. The design of the elastic support column 16 ensures the accurate adjustment of the pressure of the die cutting tool 5, and the guide 13 and the sliding positioning module 14 further improve the motion stability of the die cutting assembly 1. The setting of the shock pad 17 effectively reduces the vibration and noise in the equipment operation process, providing protection for the long-term stable operation of the equipment.

[0038] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
