Description

Technical Field

[0001] This utility model relates to the field of surface printing technology, and more specifically, to a surface printing apparatus for cardboard processing. Background Technology

[0002] Paperboard, also known as board paper, is a medium-thickness paper material made from plant fibers (such as wood, bamboo, sugarcane bagasse, etc.) through processes such as pulping, papermaking, calendering, and drying. It combines rigidity and flexibility.

[0003] With the rapid development of e-commerce and logistics, the demand for cardboard products such as cartons and packaging boxes has surged. Among them, composite cardboard is made of multiple layers of paper or fiberboard bonded together, which improves its impact resistance by 3-5 times. Corrugated cardboard is made of corrugated core paper bonded with face paper / liner paper to form a three-dimensional support structure, which improves its cushioning performance by more than 60%. Composite cardboard and corrugated cardboard are mostly used in e-commerce logistics boxes. Therefore, cardboard needs to be printed on its surface during the processing due to the requirements of use. Cardboard surface printing has the functions of information carrying and brand communication. Mass printing can quickly respond to market demand and provide a high-quality, low-cost cardboard supply to the market.

[0038] Intermittent feeding mechanism 6 is mounted on two sets of tail fixing rods 4. Intermittent feeding mechanism 6 includes intermittent drive component 60 and feeding component 61, which are used to drive the cardboard to intermittently feed.

[0042] like Figure 1-4 As shown, in a preferred embodiment, based on the above method, the intermittent drive assembly 60 further includes an L-shaped plate 601 fixedly installed on the outer wall of one of the sets of fixed rods 4, a rotary motor 602 fixedly installed on the vertical section of the L-shaped plate 601, an output shaft 603 installed at the output end of the rotary motor 602, a semi-circular cam 604 fixedly installed at the end of the output shaft 603 away from the rotary motor 602, a first rotating shaft 605 rotatably connected between the two sets of tail fixed rods 4, a chuck 606 fixedly installed at the end of the first rotating shaft 605 near the L-shaped plate 601, slots evenly opened at the four corners of the chuck 606, a rotating arm 607 fixedly installed in the middle section of the output shaft 603, and a lever 608 fixedly installed on the rotating arm 607.

[0043] like Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, in a preferred embodiment, based on the above method, the feeding assembly 61 further includes a central mounting base 611 fixedly installed on the outer wall of the first rotating shaft 605, a clamping box 612 fixedly installed on the four sides of the central mounting base 611, compression springs 613 fixedly installed in the inner cavity of the clamping box 612 and symmetrically distributed, a push plate 614 fixedly installed at one end of the compression spring 613, a baffle 615 symmetrically installed at one end of the clamping box 612 away from the central mounting base 611, a fixing block 616 fixedly installed on the outer wall of the clamping box 612 and evenly distributed, a first connecting plate 617 fixedly installed on the outer wall of the fixing block 616, a second connecting plate 618 rotatably connected to one end of the first connecting plate 617, and a return spring 619 fixedly connected between the first connecting plate 617 and the second connecting plate 618. The push plate 614 is slidably connected to the clamping box 612 to realize the positioning and preparation of the cardboard in the clamping box 612 for feeding.

[0044] like Figure 1-3 As shown, in a preferred embodiment, based on the above method, the reciprocating swing assembly 7 further includes a first connecting rod 701 fixedly installed at the center of the outer wall of the semi-circular cam 604, a second connecting rod 702 rotatably connected to the end of the first connecting rod 701 away from the semi-circular cam 604, a third connecting rod 703 rotatably connected to the end of the second connecting rod 702 away from the first connecting rod 701, a second rotating shaft 704 fixedly installed at the end of the third connecting rod 703 away from the second connecting rod 702, fixed rods 705 fixedly installed on the outer wall of the second rotating shaft 704 and symmetrically distributed, a swing rod 706 rotatably connected to the end of the fixed rod 705 away from the second rotating shaft 704, a sliding groove formed on the inner wall of the swing rod 706, and limiting blocks 707 rotatably connected to the inner side wall of the end fixed rod 2 and symmetrically distributed. The limiting blocks 707 are slidably connected to the sliding groove formed on the inner wall of the swing rod 706. The second rotating shaft 704 is rotatably connected between the two sets of middle fixed rods 3, thereby enabling the swing rod 706 to reciprocate.

[0045] like Figure 1-3 As shown, in a preferred embodiment, based on the above method, the end of the swing rod 706 away from the end fixing rod 2 is further fixedly connected to the printing machine 8, and the printing machine 8 abuts against the cardboard in the inner cavity of an assembly clamp 612 close to the printing machine 8 during the swing process, so as to realize the printing on the surface of the cardboard.

[0046] like Figure 2 As shown, in a preferred embodiment, based on the above method, a backstop component 12 is further installed on the outer wall of the tail fixing rod 4 that is away from the intermittent drive component 60 group, and the backstop component 12 is away from the chuck 606, which can prevent the chuck 606 from reversing during rotation, and ensure that intermittent feeding can be performed in a predetermined direction and rhythm.

[0047] Specifically, when the surface printing device for cardboard processing is in operation: First, the operator manually pushes the two sets of baffles 615 towards both ends of the clamping box 612 to fully expose the feeding end of the clamping box 612. Then, the stacked cardboard is placed in the inner cavity of the clamping box 612. At this time, the compression spring 613 is in a compressed state. Then, by manually pushing the two sets of baffles 615 towards the middle of the clamping box 612, the two ends of the cardboard placed in the inner cavity of the clamping box 612 can be blocked. At the same time, the compression spring 613 rebounds, and the rebound force drives the push plate 614 to push the cardboard, so that the cardboard at the outermost end is always in contact with the baffle 615. At the same time, under the force of the push plate 614, the cardboard is pressed tightly against the baffle 615 to prevent the baffle 615 from sliding or displacing. By repeating the above operation, the stacked cardboard is installed in the inner cavity of the clamping box 612 in sequence, realizing the positioning and preparation of the cardboard in the clamping box 612 for feeding.

[0048] The rotary motor 602 is started, which drives the output shaft 603 to rotate. The semi-circular cam 604 at one end of the output shaft 603 rotates accordingly. At the same time, the rotating arm 607 in the middle of the output shaft 603 also rotates. This causes the chuck 606 to rotate at a certain angle through the lever 608 mounted on the rotating arm 607. When the semi-circular cam 604 rotates to contact the chuck 606, the lever 608 just engages in the next slot, thereby driving the chuck 606 and the first rotating shaft 605 to rotate intermittently.

[0049] When the first rotating shaft 605 rotates, it drives the middle mounting base 611 on its outer wall to rotate, which in turn causes the clamping box 612 fixedly installed on the four sides of the middle mounting base 611 to rotate intermittently. When the clamping box 612 rotates to the designated position, the intermittent feeding of the cardboard is completed.

[0050] When the semi-circular cam 604 rotates, it drives the first connecting rod 701 at the center of its outer wall to move. The first connecting rod 701 drives the second connecting rod 702 to rotate, and the second connecting rod 702 drives the third connecting rod 703 to move. The third connecting rod 703 drives the second rotating shaft 704 to rotate. The fixed rod 705 on the outer wall of the second rotating shaft 704 rotates accordingly, causing the swing rod 706, which is rotatably connected to one end of the fixed rod 705, to oscillate back and forth. Since the sliding groove on the inner wall of the swing rod 706 is slidably connected to the limiting block 707 rotatably connected to the inner side wall of the end fixed rod 2, it plays a limiting and guiding role in the swing of the swing rod 706, ensuring that the swing rod 706 swings stably.

[0051] When the swing lever 706 swings back and forth, it drives the printing press 8 to swing back and forth. During the swinging process, the printing press 8 comes into contact with the cardboard in the inner cavity of a nearby assembly box 612, while the ink cartridge 5 provides ink to the printing press 8, thereby realizing printing on the surface of the cardboard;

[0052] By using the anti-reverse component 12, which includes a ratchet fixedly installed at one end of the first rotating shaft 605 and a ratchet tooth rotatably connected to the outer wall of the tail fixing rod 4, the chuck 606 can be prevented from reversing during rotation, ensuring that the intermittent feeding mechanism 6 can perform intermittent feeding according to the predetermined direction and rhythm.

[0053] After the cardboard is printed, the clamping box 612 rotates intermittently. When the clamping box 612 rotates to the unloading station, the unloading hook 11 is inserted into the edge of the cardboard under the tension of the tension spring 10, realizing automatic unloading.

[0054] All technical features in this embodiment can be freely combined according to actual needs.

[0055] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
