Description

Technical Field

[0001] The present application relates to the field of paper cutters, and in particular to a paper scrap collecting device. Background Art

[0002] The printing die-cutting machine is also called a die-cutting machine, a cutting machine, or a CNC punching machine. The printing die-cutting machine uses steel knives, hardware molds, steel wires (or templates carved from steel plates) to apply a certain amount of pressure through the stamping plate to cut printed products or cardboard into a certain shape. It is an important equipment for post-printing packaging processing and molding.

[0003] Patent publication number CN217648499U discloses a waste cleaning device for a printing die-cutting machine, which has the following deficiencies:

[0004] The paper scraps fall between the two extrusion plates through the chute. However, the top of the collection chamber formed between the two extrusion plates is not sealed. When the hydraulic cylinder drives the extrusion plates to squeeze the paper scraps, the paper scraps themselves are loose and easy to deform. When subjected to lateral extrusion, they are easily displaced upward. The paper scraps slide out from between the two extrusion plates and fall into the space outside the collection chamber in the collection chute. They are left in the collection chute, so that the paper scraps in the collection chute are not completely cleaned and collected, and the cleaning and collection efficiency is low. Utility Model Content

[0022] By adopting the above technical solution, when the cam rotates to the convex end, the cam pushes the sliding plate that contacts the surface thereof, slides the slide rod into the slot, and indirectly fixes the guide plate 2 to the rotating shaft 3. Then, the cam is rotated 90 degrees, and the cam no longer presses the sliding plate. The sliding plate rebounds to its original position under the action of the spring 2, and the slide rod slides out of the slot. The guide plate 2 is no longer fixed to the rotating shaft 3.

[0023] Preferably, a feed port is provided on the top of the collection box near the paper cutter, a guide plate is fixedly provided in the feed port, a cover plate is rotatably installed on the bottom of the collection box, and a handle is fixedly provided on the bottom of the cover plate.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By setting a rotating component, the end of the guide plate 2 away from the rotating shaft 1 can be tilted downward, so that the paper scraps can slide accurately between the two extrusion plates. When the collection is completed, the guide plate 2 is rotated to a horizontal position again by the rotating component, and then the sliding rod is slid out of the slot by setting a sliding component, so that the guide plate 2 and the rotating shaft 3 are no longer fixed. The guide plate 2 is lowered by the lifting mechanism until the guide plate 2 abuts against the top of the two extrusion plates. The top of the collection groove formed by the two extrusion plates is sealed by the guide plate 2, which prevents the debris from sliding out of the top of the collection groove formed by the two extrusion plates when the two extrusion plates slide toward each other, and prevents the paper scraps from sliding into the space outside the collection groove in the collection box and being missed in the collection box, thereby improving the efficiency of cleaning and collecting paper scraps.

The slide bar 22 is fixedly connected to the rotating shaft 3 191, and the indirect guide plate 2 16 is also fixed to the rotating shaft 3 191. When the guide plate 2 16 needs to slide down, the slide bar 22 will not be fixedly connected to the rotating shaft 3 191. At this time, the electromagnet 221 needs to be powered off and the motor 3 2312 needs to be started again. The output shaft of the motor 3 2312 drives the cam 234 to rotate 90 degrees. At this time, the cam 234 no longer presses against the two slides 231, and the two slides 231 will no longer be subjected to the force given by the cam 234. Under the action of the spring 233, the two slides 231 rebound and slide to their original positions, thereby driving the two slide bars 22 to slide to their original positions.
