Description

Technical Field

[0001] The utility model relates to the technical field of printing die-cutting machines, in particular to a printing die-cutting machine used for printing production. Background Art

[0002] Die-cutting machine is also called beer machine, cutting machine, CNC punching machine, mainly used for die-cutting (full cut, half cut), embossing and hot stamping, laminating, automatic waste discharge of some corresponding non-metallic materials, self-adhesive, EV feed port, double-sided tape, electronics, mobile phone pads, etc. Die-cutting machine uses steel knife, hardware mold, steel wire (or template carved from steel plate), and applies a certain pressure through the stamping plate to roll and cut the printed product or cardboard into a certain shape. It is an important equipment for post-printing packaging processing and molding. The working principle of the die-cutting machine is to use die-cutting knife, steel knife, hardware mold, steel wire (or template carved from steel plate), and apply a certain pressure through the stamping plate to roll and cut the printed product or cardboard into a certain shape. If the entire printed product is pressed and cut into a single graphic product, it is called die-cutting; if a steel wire is used to press out a mark or leave a bent groove mark on the printed product, it is called indentation; if two positive and negative templates are used, and the mold is heated to a certain temperature, a pattern or font with a three-dimensional effect is hot-stamped on the surface of the printed product, it is called hot stamping; if one substrate is copied on another substrate, it is called lamination; excluding the rest except the genuine product is called waste discharge; the above can be collectively referred to as die-cutting technology. The scraps cut off by the existing fully automatic die-cutting machine after die-cutting are completed will not be removed during the cutting process. Some of the cut scraps will still be stuck in the cut of the cardboard or be carried up by the cutter and attached to the cardboard. These scraps will be transported to the subsequent processing steps along with the processed products, causing unnecessary trouble to other steps. When the products are packaged and sorted manually later, the uncleaned scraps need to be removed, which wastes labor and reduces work efficiency. Utility Model Content

The transmission connecting rod 43 enables the transmission assembly 2 to move with the die-cutting assembly 4. The transmission assembly 2 includes a secondary tooth plate 22. A rack is arranged on one side of the secondary tooth plate 22. The side of the secondary tooth plate 22 without the rack is fixedly connected to the die-cutting assembly 4. When the die-cutting assembly 4 moves up and down, the transmission connecting rod 43 drives the secondary tooth plate 22 to slide up and down. A main tooth plate 21 is arranged opposite to the side of the secondary tooth plate 22 away from the die-cutting assembly 4. A gear is arranged between the main tooth plate 21 and the secondary tooth plate 22. A transmission screw 23 is provided, and racks are provided on one side of the main tooth plate 21 and the auxiliary tooth plate 22 and meshed with the transmission screw 23. The transmission screw 23 is fixed in the transmission component housing 24 by a pin so that the transmission screw 23 can rotate in the middle of the transmission component housing 24. When the auxiliary tooth plate 22 slides up and down, the main tooth plate 21 slides in the opposite direction through the transmission screw 23. The transmission component housing 24 has two slide grooves on both sides of the main tooth plate 21 and the auxiliary tooth plate 22, and sliders are provided on the left and right side walls of the main tooth plate 21 and the auxiliary tooth plate 22. Through the combination of the slide groove and the slider, the internal components are restricted to slide only through the slide groove, thereby avoiding derailment and causing machine failure.

[0028] A rocker assembly 5 is provided at the bottom of the main tooth plate 21. The rocker assembly 5 is meshed with the rack at the bottom of the main tooth plate 21 through a rocker screw 52. When the main tooth plate 21 moves downward, the rocker screw 52 rotates accordingly. A fixing plate 51 is provided on the side of the rocker screw 52 close to the discharge port. The rocker screw 52 is hinged on the fixing plate 51 through a concentric latch so that the rocker screw 52 is fixed on the fixing plate 51 and rotates. A rocker screw piece 53 is coaxially fixedly installed on the side of the rocker screw 52 close to the feed port. A rocker 54 is hinged on the side of the rocker screw piece 53 close to the feed port through an eccentric latch. The rocker 54 is away from the rocker screw piece 53. A disc cam 55 is hinged on one side of the die-cutting component 4 through an eccentric latch. When the rocker screw 52 rotates, it drives the rocker screw piece 53 to rotate, causing the rocker 54 to swing, thereby driving the disc cam 55 to rotate. The eccentric latch of the disc cam 55 is set at the protruding position of the disc cam 55. The disc cam 55 is hinged on the fixed plate 51 through a concentric latch, so that the protrusion of the disc cam 55 can rotate around the concentric latch. A pin assembly 6 is set on the side of the disc cam 55 close to the die-cutting component 4. The pin assembly 6 includes a contact roller 61. When the arc surface of the contact roller 61 contacts the arc surface of the disc cam 55, the pin assembly 6 moves up. When the arc surface of the wheel 61 does not contact the arc surface of the disc cam 55, the ejector assembly 6 will move downward. Two contact roller connecting members 62 are arranged on the side of the contact roller 61, so that the contact roller 61 rotates between the two contact roller connecting members 62. A spring base 63 is fixedly installed on one side of the two contact roller connecting members 62 close to the die-cutting assembly 4. The contact roller 61 drives the spring base 63 to move through the two contact roller connecting members 62. An ejector assembly housing 66 is arranged outside the spring base 63. There is a cavity between the spring base 63 and the ejector assembly housing 66, so that the spring base 63 slides up and down in the ejector assembly housing 66. A ejector pin 65 and a spring 64 are fixedly installed on one side of the movable spring base 63 close to the die-cutting component 4. The ejector pin 65 is sleeved in the spring 64. When the protrusion of the disc cam 55 contacts and lifts the contact roller 61, the spring 64 is compressed, so that the ejector pin 65 protrudes out of the cutter hole to eject the cut scraps from the paperboard. When the protrusion of the disc cam 55 moves away from the contact roller 61, the spring 64 recovers its deformation, so that the ejector pin 65 is retracted into the cutter hole and waits for paper to be fed again. The ejector pin assembly housing 66 is fixedly connected to the die-cutting pad 14 on one side close to the die-cutting component 4, so that only the ejector pin 65 in the ejector pin assembly 6 can be extended and retracted in the cutter hole.

[0029] After die-cutting by the die-cutting pad 14, the cardboard is transported to the collecting slider 13 set on the side of the die-cutting pad 14 close to the brush baffle 11 under the push of the transport component 3. The collecting slider 13 scrapes off the scraps attached to the cardboard through the brush baffle 11 set on the discharge port. The cardboard leaves the printing die-cutting machine through the discharge port. A gap is set between the collecting slider 13 and the die-cutting pad 14, and the scraps scraped off by the brush baffle 11 fall through the gap. The side where the collecting slider 13 and the die-cutting pad 14 are close to each other is set as opposite bevel surfaces to avoid the cardboard from getting stuck when passing through the gap, which requires manual intervention.

[0030] When the printing die-cutting machine for printing production of this embodiment is used, the cardboard is stuck in two cardboard cards 15 and placed on the cardboard rack 12 from the feed port and pushed to the contact paper transport roller 31 and the conveyor belt 32. After being transported by the transport component 3, the cardboard arrives on the die-cutting pad 14. At this time, the die-cutting component 4 presses the cutting head 41 downward to die-cut the cardboard. At the same time, the transmission connecting rod 43 drives the auxiliary tooth plate 22 to move downward to move the bottom of the main tooth plate 21 upward. The rack at the bottom of the main tooth plate 21 drives the rocker screw 52 to rotate so that the rocker screw piece 53 drives the rocker 54 to swing through the eccentric latch, so that the protrusion of the disc cam 55 is away from the contact roller 61. At this time, the spring 64 recovers its deformation to generate a downward force. The ejector pin 65 is stored in the cutter hole. When the die-cutting is completed, the die-cutting component 4 moves upward and drives the protrusion of the disc cam 55 to move upward to the lifting contact roller 61 through the transmission component 2, so that the ejector pin 65 ejects the scraps in the cardboard cut. The ejected scraps adhere to the cardboard and are pushed to the discharge port by the cardboard by the transportation component 3. After passing through the brush baffle 11 provided on the discharge port, the scraps are scraped off and fall from the gap between the collecting slider 13 and the die-cutting pad 14 along the oblique surface of the collecting slider 13, thereby avoiding these scraps from being transported to the subsequent processing steps along with the processed products, causing unnecessary trouble to other steps, reducing labor consumption, and improving work efficiency.
