Description

Technical Field

[0001] This invention relates to the field of die-cutting equipment technology, and specifically discloses a combined multi-functional intermittent die-cutting machine. Background Technology

[0002] A die-cutting machine is a device that continuously and efficiently cuts wide-width cardboard, rolls, and other materials. During operation, a rotating blade roller drives ring-shaped cutters arranged at intervals to achieve the slitting process. An intermittent die-cutting machine is based on a standard die-cutting machine but, to meet specific intermittent processing needs, modifies the continuous drive structure to an intermittent drive structure, allowing the blade roller to rotate intermittently. Currently, in existing die-cutting machines, the die-cutting mechanism is located inside the machine casing, and the ring-shaped cutters within the mechanism are spaced apart on the outer surface of the blade roller using bolts or other connecting components.

[0003] For example, invention patent application number 2022111487222 discloses a die-cutting machine for corrugated cardboard, which includes a machine casing, a machine cover, and a slitting roller. A conveying mechanism is located at the upper end of the machine casing, and the machine cover is located above the conveying mechanism. The slitting roller is rotatably mounted inside the machine cover. Several strip-shaped grooves are formed on the roller body of the slitting roller, and toothed surfaces are provided on the bottom walls of the strip-shaped grooves. Multiple cutter discs are provided on the slitting roller, and mounting rings fitted onto the cutter discs are connected to the cutter discs. A locking block is provided in the mounting ring, and the locking block has locking teeth that mesh with the toothed surfaces. An adjusting component is provided on the mounting ring, and a telescopic drive component is provided on the machine cover. The end of the telescopic drive component extending into the machine cover is connected to a grinding block aligned with both ends of the slitting roller. The die-cutting mechanism of the die-cutting machine disclosed in this patent is located inside the machine casing, and the cutter discs are fixed to the outer surface of the slitting roller by bolts. In actual operation, the distance between the various blades on the slitting roller needs to be adjusted according to the actual situation. However, the blade adjustment in this patent requires opening the machine casing, entering, and using tools to loosen bolts, making the entire operation very complex and cumbersome. Furthermore, this die-cutting machine has a limited function; in addition to printing and drying processes in cardboard processing, it requires corresponding processing equipment to meet the cardboard processing needs. Therefore, to address the above-mentioned shortcomings of existing corrugated cardboard die-cutting machines, this application proposes a combined multi-functional intermittent die-cutting machine to achieve rapid automatic adjustment of the blades in the die-cutting mechanism and to realize its printing and drying processes.

[0011] As a further provision of the above solution, a drying unit is also provided between the printing unit and the die-cutting unit. The drying unit includes a hot air blower fixed on the upper surface of the processing machine housing. The air outlet of the hot air blower is connected to a hot air pipe. The end of the hot air pipe passes through the side wall of the processing machine housing and is located between the printing unit and the die-cutting unit. Multiple exhaust ports are spaced apart on the lower surface of the hot air pipe inside the processing machine housing.

[0012] As a further provision of the above scheme, the drive unit includes a drive motor fixed on the outer side of the processing machine housing. The end of the motor shaft of the drive motor extending into the processing machine housing is connected to an incomplete gear. A transmission gear that meshes with the incomplete gear is rotatably connected to the inner wall of the processing machine housing.

[0017] Beneficial effects:

[0018] 1) When adjusting the cutter for different width slitting requirements, the combined multi-functional intermittent die-cutting machine disclosed in this invention first controls the first telescopic drive component to retract, thereby removing the force between the trapezoidal push block and the wedge block. At this time, under the action of the spring, all the expansion and contraction racks on the die-cutting roller retract into the axial groove. At this time, all the cutters move axially along the die-cutting roller evenly. Then, the control unit is activated to make the carrier plate move axially above the die-cutting roller. During its movement, the camera captures the position of the cutter. After the position of all cutters is captured, the control unit pushes the cutter to the set position one by one. Finally, the first telescopic drive component is extended, and then all the expansion and contraction racks move axially outward through the action of the trapezoidal push block. Then, the adjusted cutter is quickly fixed by the engagement action of the expansion and contraction racks and the slot on the upper tooth surface of the cutter. The entire combined multi-functional intermittent die-cutting machine has the function of automatically and quickly adjusting the cutter position, which can meet the needs of quick cutter adjustment during the slitting process of various types of cardboard.

[0019] 2) This invention further refines the combined multi-functional intermittent die-cutting machine by utilizing a drive unit to synchronize the rotation of the die-cutting roller and the printing roller, thereby realizing the printing, drying, and slitting processes in the paperboard production process. This makes the die-cutting machine multifunctional, achieving a multi-purpose effect. Furthermore, this invention also includes a grinding block above the end of the die-cutting roller. When the cutter becomes dull after prolonged operation, the aforementioned control unit moves all the cutters together, and then the second telescopic drive component moves the grinding block towards the cutter until the grinding edge contacts the cutter. The cutter is then ground during the rotation of the die-cutting roller, ensuring the die-cutting unit always maintains high slitting efficiency and greatly improving the overall performance of the die-cutting machine.

Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0040] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The following will refer to the appendix... Figures 1-9 This application will be described in detail with reference to the embodiments.

[0041] Example 1

[0042] Example 1 discloses a combined multi-functional intermittent die-cutting machine, see attached figure. Figure 1 and attached Figure 2 The die-cutting machine mainly comprises a conveyor base 1, a processing housing 2, and a feeding unit 3. The processing housing 2 is located at the upper end of the conveyor base 1, and the feeding unit 3 is located in the conveyor base 1 directly below the processing housing 2. Specifically, the feeding unit 3 includes a row of conveyor rollers 301 arranged in the conveyor groove at the upper end of the conveyor base 1, and a power unit 302 is provided on the front side of the conveyor base 1 to drive the row of conveyor rollers 301 to rotate synchronously. During operation, the cardboard to be cut is placed at one end of the conveyor rollers 301, and then driven by the power unit 302, it is fed into the processing housing 2 for processing.

[0043] Reference Appendix Figure 3 Appendix Figure 4 and attached Figure 5 A printing unit 4 is provided in the inner cavity of the processing machine housing 2, and a control unit 6 is provided in the processing machine housing 2 located directly above the die-cutting unit 5 to adjust the movement of the cutter 502 in the die-cutting unit 5. At the same time, a drive unit 7 is provided on the rear side of the processing machine housing 2 to realize the synchronous intermittent operation of the printing unit 4 and the die-cutting unit 5.

[0044] The specific die-cutting unit 5 includes a die-cutting roller 501 rotatably mounted in the processing housing 2 and several cutters 502. Several axial grooves 503 are evenly formed on the outer circular surface of the die-cutting roller 501. In this figure, there are two axial grooves 503, which are respectively located at the upper and lower ends of the outer circular surface of the die-cutting roller 501. At the same time, a columnar cavity 500 communicating with the side end of the axial grooves 503 is formed at one end of the die-cutting roller 501. Each axial groove 503 is connected to an expansion rack 505 by a spring 504, with the tooth surface of the expansion rack 505 facing outwards. In order to prevent the expansion rack 505 from deviating during radial movement, this embodiment also provides a plurality of radial guide holes 5031 spaced apart on the bottom wall of each axial groove 503. Then, a guide post 509 inserted into the radial guide hole 5031 is connected to the inner side of the expansion rack 505. When the expansion rack 505 moves radially, it is acted upon by the guide post 509 and the radial guide hole 5031, effectively preventing it from deviating during movement.

[0045] A wedge block 506 extending into the cylindrical cavity 500 is connected to the same end of each axial groove 503, and the wedge block 506 is arranged with a tapered arc surface facing the central axis of the die-cutting roller 501. A first telescopic drive member 507 is fixedly installed on the processing housing 2 near the cylindrical cavity 500. The first telescopic drive member 507 is preferably a cylinder. The piston rod of the first telescopic drive member 507 passes through the hollow rotating shaft of the die-cutting roller 501 and extends into the cylindrical cavity 500. A trapezoidal push block 508 adapted to the wedge block 506 is rotatably connected to the end of the piston rod of the first telescopic drive member 507. By the extension or retraction of the first telescopic drive member 507, the trapezoidal push block 508 can be pushed to move towards the wedge block 506, thereby squeezing the wedge block 506 and causing the expansion and contraction rack 505 in the axial groove 503 to move radially outward against the force of the spring 504. Meanwhile, several cutters 502 are spaced and fitted onto the outer surface of the die-cutting roller 501 according to the required cutting spacing, and a toothed groove adapted to the expansion and contraction rack 505 is formed on the inner ring wall of each cutter 502. When the expansion and contraction rack 505 extends out of the axial groove 503, it can engage with the toothed groove, thereby fixing the cutter 502.

One end of the transmission screw 603 is connected to a screw motor 604 on the outer wall of the processing machine housing 2. A screw-hole movable block 605 matching the transmission screw 603 is provided in the movable groove 602, and a carrier plate 606 is connected to the lower end of the screw-hole movable block 605. During the position adjustment of the cutter, the forward and reverse rotation of the screw motor 604 can be controlled, and the carrier plate 606 can reciprocate along the axial direction of the die-cutting roller 501 under the combined action of the transmission screw 603 and the screw-hole movable block 605.

[0047] A camera 607 and a light 608 are provided on the carrier plate 606, facing the die-cutting unit 5, and the camera 607 is electrically connected to the control system in the die-cutting machine. A U-shaped bracket 609 is rotatably connected to the end opening of the carrier plate 606, and the opening width of the U-shaped bracket 609 is greater than the thickness of the cutter 502. A drive device for rotating the U-shaped bracket 609 is also provided on the carrier plate 606. Specifically, the drive device includes a telescopic rod 610 rotatably connected to the carrier plate 606, a circular plate 611 connected to the pin end at the rotatable connection of the U-shaped bracket 609, and the movable end of the telescopic rod 610 connected to a convex shaft at a non-central location on the circular plate 611. When the position of the cutter 502 in the die-cutting unit 5 needs to be adjusted, a light source is provided by the lighting lamp 608 during the axial movement of the carrier plate 606. Then, the position of the cutter 502 is captured by the camera 607.

After the cutter 502 is locked into the U-shaped bracket 609, the movement of the carrier plate 606 is controlled by the lead screw motor 604. During the movement of the carrier plate 606, the cutter 502 is moved to the designated position on the die-cutting roller 501. Finally, after all the cutter 502 positions are adjusted, they are fixed by the locking action of the expansion and contraction rack 505.

The aforementioned drive unit 7 uses the drive motor 701 as the power input source, and then utilizes the intermittent transmission between the incomplete gear 702 and the transmission gear 703 to cause the first driven wheel 705 to rotate intermittently, thereby causing the die-cutting roller 501 to perform intermittent slitting processing according to the slitting requirements.

[0055] The combined multi-functional intermittent die-cutting machine disclosed in Embodiment 2, in addition to having the function of quickly adjusting the cutter 502 as in Embodiment 1, can also synchronously drive the die-cutting roller 501 and the printing roller 401 to rotate through the closed-loop transmission component 707, so as to achieve printing processing on the surface of the cardboard before die-cutting. Specifically, the printing process involves the rotating printing roller 401 contacting the lower end of the dye brush 403, thereby uniformly coating the dye on the outer circular surface of the printing roller 401. Then, the printing roller 401 is used to print the pattern on the surface of the cardboard. After printing is completed, the dye on the surface is dried by the hot air sent by the drying unit 8. After the printed pattern is set, the subsequent slitting process is carried out.
