Description

Technical Field

[0001] This utility model relates to the field of cardboard box processing, specifically to a pressing device for cardboard box processing. Background Technology

[0002] The edge pressing device for carton processing is an important piece of equipment in the carton production process. It is mainly used to process the edges of the carton. By applying a certain pressure, the shape of the edge material of the carton is changed. Generally, the pressure generated by the mechanical structure is used to flatten or press the cardboard at the edge of the carton into a specific shape.

[0003] CN214774297U discloses a pressing device for cardboard box processing, including a support box. A first motor is fixedly connected to the rear side of the inner cavity of the support box, and a turntable is fixedly connected to the output end of the first motor. A transmission shaft is fixedly connected to the top of the front of the turntable, and a crossbar is slidably connected to the inner cavity of the support box. In the current booming development of the modern packaging industry, cardboard boxes, as the most commonly used outer packaging carrier for various products, have crucial processing quality. As a key piece of equipment in the cardboard box forming process, the pressing device directly affects the edge strength, sealing performance, and overall appearance quality of the cardboard box. With the scaling up and increasing efficiency of cardboard box production, the pressing device operates under continuous high-intensity working conditions. On the one hand, cardboard box processing workshops are usually not completely clean spaces; the handling and stacking of paper raw materials generates a large amount of dust, and pre-processing such as cutting and printing also produces many paper scraps, ink particles, and other impurities. On the other hand, during the operation of the pressing device itself, the friction and wear of mechanical parts also generate fine debris. These dust and impurities easily adhere to the surface of the edge-pressing mold during the edge-pressing process. When dust and impurities are present on the mold surface, the subsequent edge-pressing quality will be greatly reduced. During the pressure application stage, impurity particles will disrupt the uniform distribution of pressure, causing localized excessive or insufficient pressure on the edges of the carton. This results in weak edge pressing, making the carton edges prone to spreading and unable to form a tight and sturdy structure. These impurities will also leave unsightly marks on the carton edges, such as scratches, bumps, or dents, greatly affecting the smoothness of the carton's appearance and making the originally smooth carton rough and unsightly, thus reducing the edge-pressing quality. Utility Model Content

[0021] Please see Figures 1-5 The present invention provides a technical solution: a pressing device for carton processing, comprising a base 1, a first support plate 2 fixedly connected to one side above the base 1, a cylinder 3 fixedly connected to the first support plate 2, a first pressure plate 4 fixedly connected to the other side above the base 1, a pneumatic rod 5 fixedly connected to the output end of the cylinder 3, a second pressure plate 8 fixedly connected to the lower end of the pneumatic rod 5, a sliding mechanism 6 provided on the outside of the pneumatic rod 5, and a swing mechanism 7 provided below the sliding mechanism 6;

[0022] The sliding mechanism 6 includes a first push rod 601 fixedly connected to the outside of the gas spring 5. A first hole 602 is provided inside the upper part of the first support plate 2. A first push plate 603 is slidably connected to the inside of the first hole 602. A second hole 604 is connected to the lower part of the first hole 602. A second push plate 615 is provided inside the second hole 604. A third hole 605 is provided inside the end of the second push plate 615 away from the first support plate 2. A fourth push rod 606 fixedly connected to the first push plate 603 is provided inside the third hole 605. The lateral width of the third hole 605 is greater than the lateral width of the fourth push rod 606. The second push plate 615 has a first guide groove 607 in the middle, and a first guide rod 608 fixedly connected to the first support plate 2 is provided inside the first guide groove 607. Second guide grooves 609 are provided on both sides of the second push plate 615, and second guide rods 610 fixedly connected to the first support plate 2 are provided inside the second guide grooves 609. A first cleaning cloth 611 is fixedly connected to the upper middle of the second push plate 615. First baffles 612 slidably connected to the first support plate 2 are provided on the upper sides of the second push plate 615. A third guide groove 613 is provided on the inner side of the first push plate 603. A third guide rod 614, which is fixedly connected to the first push plate 603, is provided on the inner side of the third guide groove 613. The lower end of the third guide groove 613 has a vertical straight line shape, and the upper end of the third guide groove 613 has an inclined straight line shape. The third guide groove 613 and the third guide rod 614 are fitted with a clearance fit, so that when the third guide rod 614 moves at the lower end of the third guide groove 613, it will not drive the first push plate 603 to move back and forth. When the third guide rod 614 moves at the upper end of the third guide groove 613... The first push plate 603 will move back and forth. The first guide groove 607 has a wave-shaped appearance and the first guide rod 608 is fitted with a clearance fit. When the first guide rod 608 moves inside the first guide groove 607, it can drive the second push plate 615 to move left and right. The second guide groove 609 has an inclined straight shape and the second guide rod 610 is fitted with a clearance fit. When the second guide rod 610 moves inside the second guide groove 609, it can drive the second push plate 615 to move up and down.

[0023] The swing mechanism 7 includes a third push rod 701 disposed on the inner side below the third hole 605. The lower end of the third push rod 701 is fixedly connected to a third push plate 702. A fourth guide groove 703 is disposed in the middle of the third push plate 702. A fourth guide rod 704 fixedly connected to the first support plate 2 is disposed on the inner side of the fourth guide groove 703. A second cleaning cloth 705 is fixedly connected to the lower two sides of the third push plate 702. A second baffle 706 fixedly connected to the first support plate 2 is disposed on the upper sides of the third push plate 702. The fourth guide groove 703 has a wave-shaped appearance and the fourth guide rod 704 is fitted with a clearance fit, so that the fourth guide rod 704 can move when it moves inside the fourth guide groove 703.

[0024] After the cylinder 3 drives the air rod 5 and the second pressure plate 8 to press the edges of the carton, the cylinder 3 drives the air rod 5 and the second pressure plate 8 to move upward, which in turn drives the first push rod 601 and the third guide rod 614 to move upward. Because the lower end of the third guide groove 613 has a vertical straight shape and the upper end of the third guide groove 613 has an inclined straight shape, and the third guide groove 613 and the third guide rod 614 are fitted with a clearance fit, when the second pressure plate 8 moves to a certain height, the third guide rod 614 moves to the inner side of the upper end of the third guide groove 613, driving the first push plate 603 to move forward. The movement of the push rod 606 and the second push plate 615 forward, and the third push rod 701 forward, causes the second push plate 615, the first cleaning cloth 611, the third push plate 702, and the second cleaning cloth 705 to move forward, cleaning the lower surface of the second pressure plate 8 and the upper surface of the first pressure plate 4. Because the appearance structure of the second guide groove 609 is an inclined straight line, and the second guide groove 609 and the second guide rod 610 are in a clearance fit, the second guide groove 609 is pushed by the second guide rod 610, causing the second push plate 615 and the first push plate 601 to move forward. The cleaning cloth 611 moves upward, allowing it to adhere to the lower surface of the second pressure plate 8. Because the first guide groove 607 has a wavy shape and its fit with the first guide rod 608 is a clearance fit, and the fourth guide groove 703 also has a wavy shape and its fit with the fourth guide rod 704 is a clearance fit, the second push plate 615 and the third push plate 702 are pushed left and right by the first guide rod 608 and the fourth guide rod 704 along the tracks of the first guide groove 607 and the fourth guide groove 703. The cleaning effect is improved by cleaning the lower surface of the second pressure plate 8 and the upper surface of the first pressure plate 4 from multiple directions. The first baffle 612 will adhere to the upper surface of the second push plate 615 and the second baffle 706 will adhere to the upper surface of the third push plate 702, reducing the chance of dust falling back to the upper surface of the first pressure plate 4. When the second push plate 615 and the third push plate 702 move out of the rear side of the first support plate 2, they will also swing to automatically discharge materials. In summary, the first pressure plate 4 and the second pressure plate 8 can be automatically cleaned after each pressing, resulting in a better pressing effect in the next pressing.
