Description

Technical Field

[0001] This invention relates to the field of die-cutting equipment technology, specifically a fully automatic rotary die-cutting machine that improves the working efficiency of the die-cutting machine by assisting in changing the die-cutting machine's blades. Background Technology

[0002] Die-cutting machines use blades to apply pressure and cut printed materials or cardboard into specific shapes. They are important equipment for post-printing packaging and forming. Rotary die-cutting machines are a type of die-cutting machine.

[0003] The rotary die-cutting machine adopts a cylindrical pressing design, meaning that both the pressing and cutting mechanism and the base plate are cylindrical. The material to be processed is fed between the two cylinders through the feeding rollers. As the two cylinders rotate, they cut the material between them. Compared with other die-cutting equipment, the rotary die-cutting machine has high working efficiency.

[0004] Because the die-cutting blades are made with curved surfaces, changing the blades on a rotary die-cutting machine is a complicated process. Workers need to remove the shaft, shaft seat, and blade together from the machine, replace the blade on the shaft, reassemble the disassembled parts, and then put them back into the die-cutting machine. During the installation process, the transmission gear on the shaft needs to be re-engaged with the gears on the machine for the die-cutting machine to work properly. Changing the die-cutting blades wastes a lot of time and reduces the efficiency of the production line. Summary of the Invention

Detailed Implementation

[0029] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0030] This invention provides a fully automatic rotary die-cutting machine, comprising: a support unit 1, a worktable 2 located on the same side of the support unit 1, and a die-cutting assembly 3. A feeding roller 11, a guide roller 12, a waste roller 13, and a finished product roller 14 are arranged on one side of the support unit 1. The feeding roller 11, guide roller 12, waste roller 13, and finished product roller 14 are all rotatably connected to the support unit 1. An electric telescopic rod 171 is fixedly connected to the inner wall of the support unit 1. A push plate 17 is fixedly connected to the output end of the electric telescopic rod 171. A blade changing assembly 18 is arranged on one side of the support unit 1. The blade changing assembly 18 includes a pair of push rods 182. A column 173, a limiting strip 172, and push rods 182 are fixedly connected to the push plate 17. A connecting rod 183 is rotatably connected to the other end of the push rod 182. A slider 184 is rotatably connected to one end of the connecting rod 183. A groove 15, a through groove 186, and a through groove 18 are formed on the side of the support unit 1. 7. A support column 16 is fixedly connected within the groove 15. The support column 16 passes through the slider 184 and is slidably connected to the slider 184. A slide plate 181 is fixedly connected to the bottom of the slider 184, and an electromagnetic plate 185 is fixedly connected to the bottom of the slide plate 181. When the die-cutting machine is working, the processed material will enter the die-cutting assembly 3 from the feeding roller 11 through the guide roller 12. After being processed by the die-cutting assembly 3, it is divided into finished products and waste materials, which are respectively separated by the waste material roller 13 and the finished product roller 14. When the winding is activated, the electric telescopic rod 171 will push the push plate 17 to move, which in turn will drive the push rod 182, the column 173 and the limit bar 172 to move. The push rod 182 is pushed out of the through slot 2 187, which will drive the connecting rod 183 to rotate. The connecting rod 183 pulls the slider 184 to move along the support column 16, so that the slide plate 181 drives the electromagnetic plate 185 to move towards each other. The electromagnetic plate 185 is arc-shaped and will generate magnetism after being energized, attracting the first tool 343 and the second tool 344.

[0031] The die-cutting assembly 3 includes a pair of mounting brackets 31 and a motor bracket 32 ​​fixedly connected to the bottom of the mounting brackets 31. A motor 321 is fixedly connected inside the motor bracket 32, and a drive wheel 322 is fixedly connected to the output end of the motor 321. A support shaft seat 311 is fixedly connected inside the mounting brackets 31, and a tool shaft seat 312 is arranged above the support shaft seat 311. The tool shaft seat 312 is fixedly connected to the mounting brackets 31, and a pressure block 314 is arranged on the top of the tool shaft seat 312. The bottom of the pressure block 314 fits against the top of the tool shaft seat 312, and a threaded rod 315 is fixedly connected to the top of the pressure block 314. A horizontal groove 316 is opened on the side of the pressure block 314 on the mounting bracket 31 near the bearing unit 1. Above the tool shaft seat 312... A top plate 313 is provided, through which the threaded rod 315 passes. The top plate 313 is fixedly connected to the mounting bracket 31. A rotating shaft 331 is provided on the support shaft seat 311, and a support roller 33 is mounted on the rotating shaft 331. A rotating shaft 342 is provided on the cutter shaft seat 312, and a cutter roller 34 is mounted on the rotating shaft 342. When the motor 321 starts, it drives the drive wheel 322 to rotate, which in turn drives the driven wheel 332 to rotate. The driven wheel 332 drives the driven wheel 341 to rotate, providing power for die cutting. By rotating the threaded rod 315, a vertical downward pressure is applied to the pressure block 314, which in turn applies downward pressure to the cutter roller 34, ensuring that it maintains a distance from the support roller 33 during operation, thus completing the die cutting work.

[0032] The rotating shaft 342 has a pair of symmetrical grooves 3411. A sleeve 347 is fitted on the rotating shaft 342. A pair of symmetrical grooves 3410 are provided on the sleeve 347. A pair of connecting seats 348 are fixedly connected to the sleeve 347. A through hole 349 is horizontally provided on the connecting seat 348. The connecting rod 3414 and the pin 3415 extend through the grooves 3411 into the grooves 3410.

[0033] The die-cutting assembly 3 includes a first cutter 343 and a second cutter 344 symmetrically arranged with the first cutter 343. Both the first cutter 343 and the second cutter 344 have a limiting block 346 on their inner walls. The limiting block 346 has a limiting hole 3418 horizontally opened on it. Multiple pins 345 are fixedly connected to the radial section of the first cutter 343. Multiple limiting holes 3417 are opened at the radial section of the second cutter 344. When the first cutter 343 and the second cutter 344 are installed on the sleeve 347, the pins 345 will pass through the through hole 349 and enter the limiting hole 3417, and the limiting block 346 will pass through the groove 3410 and enter the groove 3411.

[0034] The rotating shaft 342 is hollow and contains an elastic element 3146. One end of the elastic element 3146 is fixedly connected to the inner wall of the rotating shaft 342, and the other end of the elastic element 3146 is fixedly connected to a piston 3413. When the electric telescopic rod 171 is activated, it will push the push plate 17 to move, thereby causing the column 173 to horizontally push the piston 3413 to compress the elastic element 3146. The connecting rods 3414 symmetrically arranged on the piston 3413 will move within the groove 3411.

[0035] The piston 3413 is symmetrically fixedly connected to a connecting rod 3414. One end of the connecting rod 3414 is fixedly connected to a pin 3415. The connecting rod 3414 passes through the groove 3411 and extends into the groove 3410. The pin 3415 is located in the limiting hole 3418. When the first tool 343 and the second tool 344 are installed on the sleeve 347, the pin 3415 will enter the limiting hole 3418.

[0036] A driven wheel 332 is fixedly connected to the rotating shaft 331. The driven wheel 332 meshes with the driving wheel 322. The rotation of the driving wheel 322 will drive the driven wheel 332 to rotate, which in turn will drive the rotating shaft 331 and the supporting roller 33 to rotate.

[0037] Among them, a driven wheel 341 is fixedly connected to the second rotating shaft 342. The driven wheel 341 meshes with the first driven wheel 332. A retaining ring 3412 is provided between the sleeve 347 and the driven wheel 341. The rotation of the first driven wheel 332 drives the second driven wheel 341 to rotate, which in turn drives the second rotating shaft 342, the sleeve 347, and the first and second cutters 343 to rotate.

[0038] The retaining ring 3412 is fixedly connected to the rotating shaft 342. A protrusion 34121 is fixedly connected to the retaining ring 3412. When the push plate 17 is pushed, the limiting strip 172 will slide out from the slide groove 316 and fit with the protrusion 34121 to limit the angle at which the tool roller 34 stops rotating.

[0039] Example 1:

[0040] like Figure 1-8As shown, in this embodiment, when the rotary die-cutting machine is working normally, the control panel on the worktable 2 can control the rotation speed of each component. The disc-shaped material is mounted on the feeding roller 11. The material enters the die-cutting assembly 3 through the guide roller 12. The output end of the motor 321 drives the drive wheel 322 to rotate, which in turn drives the driven wheel 332 to rotate. The rotation of the driven wheel 332 causes the shaft 331 to rotate between a pair of support shaft seats 311. The rotation of the driven wheel 332 also drives the driven wheel 341 to rotate. The rotation of the driven wheel 341 causes the retaining ring 3412 and the shaft 342 to rotate. This causes the sleeve 347 mounted on the shaft 342 and the cutter 343 and cutter 344 on the sleeve 347 to rotate around the axis of the shaft 342 between a pair of cutter shaft seats 312. They cooperate with the support roller 33 to die-cut the material passing through. The finished product and waste material are wound up by the waste roller 13 and the finished product roller 14, respectively.

[0041] When the cutting tool wears out, or when it needs to be replaced according to production requirements, the electric telescopic rod 171 is activated. Its output end drives the push plate 17 to move, pushing the push plate 17 towards the die-cutting assembly 3. As the push plate 17 is pushed, the limiting strip 172 fixed on one side of the push plate 17 extends out from the slide groove 316, passes through the pressure block 314, and reaches above the retaining ring 3412. When the rotating shaft 342 rotates, it will drive the retaining ring 3412 to rotate. When the protrusion 34121 on the retaining ring 3412 is in contact with the limiting strip 172, the die is closed. When the motor 321 is turned off, the die-cutting assembly 3 stops moving. During the process of the push plate 17 being pushed, the column 173 will enter the rotating shaft 342 and contact the piston 3413, pushing the piston 3413 horizontally. The elastic element 3146 is compressed, and the connecting rod 3414 on the piston 3413 is pushed to move along the groove 3411, so that the pin 3415 is gradually pulled out from the limiting hole 3418 until the fixed connection between the first cutter 343 and the second cutter 344 and the rotating shaft 342 is released.

[0042] When the push plate 17 is pushed, the push rod 182 extends out of the through groove 187, thereby driving the connecting rod 183 to rotate. The connecting rod 183 pulls the slider 184 to slide along the support column 16 in the groove 15, causing the slide plate 181 and the electromagnetic plate 185 to move in opposite directions in the horizontal direction. When the pin 3415 disengages from the limiting hole 3418, the electromagnetic plate 185 will come into contact with the cutting surfaces of the first cutter 343 and the second cutter 344 to prevent the cutters from falling off the sleeve 347. At this time, the electromagnetic plate 185 is energized. 85 generates a magnetic force to attract the first cutter 343 and the second cutter 344. The electric telescopic rod 171 is activated to retract it, which moves the push plate 17 away from the die-cutting assembly 3. This causes the push rod 182 to pass through the second through slot 187 and retract into the bearing unit 1. At this time, the slider 184 will drive the slide plate 181 and the electromagnetic plate 185 to move relative to each other, and at the same time separate the first cutter 343 and the second cutter 344. The first pin 345 disengages from the first limiting hole 3417, and the cutter is removed from the sleeve 347. By de-energizing the electromagnetic plate 185, the cutter can be removed from the die-cutting machine.

[0043] To install the cutting tools, place tool one 343 and tool two 344 on the electromagnetic plate 185, energize the electromagnetic plate 185, and start the electric telescopic rod 171. Repeat the above steps until the pin one 345 enters the limiting hole one 3417. At this time, de-energize the electromagnetic plate 185. Tool one 343 and tool two 344 will be left on the sleeve 347. The limiting block 346 will pass through the groove two 3410 and enter the groove three 3411. The connecting rod 3414 will pass through the groove three 3411 and enter the groove two 3410. Then retract the electric telescopic rod 171. The elastic element 3146 will push the piston 3413 to reset, thereby causing the pin two 3415 on the connecting rod 3414 to enter the limiting hole two 3418, fixing tool one 343 and tool two 344 on the sleeve 347.

[0044] It should be noted that the combination of cutter 1 343 and cutter 2 344 forms a cylindrical shape, and the opposite side of the pair of electromagnetic plates 185 is arc-shaped, with its diameter being the same as the outer diameter of the cylinder formed by cutter 1 343 and cutter 2 344.

Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
