Description

Technical Field

[0001] This application relates to the field of die-cutting machine technology, and in particular to a feeding mechanism for a vertical die-cutting machine. Background Technology

[0002] Die-cutting machines, also known as die-cutting machines, cutting machines, or CNC punching machines, are mainly used for die-cutting, creasing, hot stamping, laminating, and automatic waste removal of various non-metallic materials, self-adhesive labels, EVA, double-sided tape, electronic and mobile phone pads, etc. Die-cutting machines use steel blades, hardware molds, and steel wires to apply a certain pressure through a printing plate to cut printed materials or cardboard into a certain shape. They are important equipment for post-printing packaging processing.

[0003] A search revealed a patent document with authorization announcement number CN215969163U, which discloses a feeding mechanism for a die-cutting machine. The mechanism includes a base plate with side plates on both sides. Multiple rotating rollers, multiple connecting rollers, and multiple connecting rods are equidistantly arranged between the side plates. Each connecting roller has a connecting shaft at both ends. An adjustment mechanism is provided within the inner cavity of a slide groove. This adjustment mechanism includes at least four screws, two positioning rods, multiple rolling wheels, a connecting groove, and two positioning grooves. Multiple connecting belts and multiple pulleys are provided within the inner cavity of the connecting groove. A servo motor is installed at one end of one of the connecting shafts. This arrangement, utilizing the cooperation between positioning rods and screws, allows for easy adjustment of the distance between the connecting rods and rotating rollers through screw rotation. This ensures that paperboard of different thicknesses can be positioned between the connecting rods and rotating rollers, enabling stable paper movement and facilitating feeding adjustments for paper of varying thicknesses, thereby improving the die-cutting efficiency of the die-cutting machine.

[0004] In practical use, it was found that traditional mechanisms lack effective cleaning methods during the feeding process. Dust, paper scraps and other impurities attached to the cardboard surface will contaminate the die-cutting blades, accelerate blade wear, and cause quality problems such as burrs and uneven cuts at the die-cutting edges, increasing equipment maintenance costs and product defect rates. Therefore, we proposed a vertical die-cutting machine feeding mechanism to solve the above problems. Utility Model Content

[0045] Specifically, a controller is installed on the front side of the function box 2, and the controller is electrically connected to the motor 201.

[0046] In this application, when the die-cutting machine is feeding material, the operator first places the cardboard onto the conveyor roller 103 from the front and pushes it, aligning the front end of the cardboard with the conveying direction of the conveyor roller 103 to ensure proper placement. Then, the motor 201 is started, and the output shaft of the motor 201 drives the drive shaft 101 to rotate. The drive shaft 101, through its connection with the first transmission wheel 7 on the corresponding driven shaft 102 and the first transmission belt 701 between them, drives the corresponding driven shaft 102 to rotate. Simultaneously, the driven shafts 102 achieve multi-axis linkage through the second transmission wheel 8 and the second transmission belt 801, enabling all conveyor rollers 103 to rotate synchronously, forming a stable conveying force, thus achieving the purpose of conveying the cardboard to the die-cutting machine. When the cardboard is pushed under the pressure roller 301, the pressure roller 301 applies appropriate pressure to the cardboard, ensuring close contact between the cardboard and the conveyor roller 103, preventing slippage during conveying, and ensuring the stability and accuracy of the cardboard conveying. Spring 5... 03 can provide constant tension to the cardboard through the elastic force of the slide block 501 and slide rod 502. When the tension of the cardboard changes, the spring 503 automatically extends and retracts to maintain stable tension, thus preventing the cardboard from wrinkling or breaking due to tension fluctuations. By activating the hydraulic cylinder 401, its output shaft can drive the tension cylinder 5 to move up and down. The position of the tension cylinder 5 can be precisely adjusted according to the thickness, material and other characteristics of the cardboard, thereby changing the initial compression of the spring 503 and achieving adaptive tension control for different cardboards. At the same time, the rotating shaft 6 can be driven by the drive shaft 101 to rotate through the third transmission wheel 9 on the drive shaft 101 and the third transmission belt 901 between them. This causes the brush on the cleaning roller 601 to rotate synchronously, enabling the brush to clean the surface of the cardboard during the conveying process. This effectively removes dust, paper scraps and other impurities, preventing these impurities from affecting the subsequent die-cutting quality and ensuring the precision and quality of the die-cut products.
