Description

Technical Field

[0001] This utility model relates to the technical field of corrugated cardboard box processing equipment, and in particular to a front-end feeding mechanism for a corrugated cardboard box printing machine. Background Technology

[0002] Corrugated cardboard boxes are boxes made of corrugated cardboard. Typically, during the production process, corrugated cardboard boxes require printing on the box body according to customer requirements.

[0003] In the prior art, such as the Chinese patent publication number CN219155479U, a digital printing machine for corrugated boxes is disclosed, which includes a digital printing machine and a worktable. Two pairs of shafts are fixedly connected to the worktable, and a drive roller and a driven roller are rotatably connected to the two pairs of shafts respectively. A conveyor belt is wound around the drive roller and the driven roller. A drive motor is fixedly fixed on the worktable, and the output end of the drive motor is coaxially fixedly connected to the drive roller. A limiting mechanism and a flattening mechanism are provided on the conveyor belt. Baffles are provided on both sides of the conveyor belt, and support platforms are provided on both sides of the baffles. A linear motor is fixed on one pair of the support platforms. This utility model lays the corrugated box flat and places it on the conveyor belt. The limiting mechanism prevents the corrugated box from shifting during transportation on the conveyor belt. The flattening mechanism makes the flattened corrugated cardboard spread evenly, preventing the corrugated box from being misprinted due to a bulge in the middle.

[0004] While the aforementioned patent can prevent printing defects in corrugated cardboard boxes, the corrugated cardboard is stacked at the inlet of the printing machine before printing. The corrugated cardboard enters the printing machine through the inlet for printing. During this process, the corrugated cardboard may not be stacked neatly, and subsequent feeding may cause misalignment, ultimately resulting in inaccurate printing positions. This utility model sets up a mechanism at the inlet to organize the corrugated cardboard stack, ensuring accurate feeding positions of the corrugated cardboard. Utility Model Content

[0005] The purpose of this invention is to provide a front-end feeding mechanism for a corrugated cardboard printing machine, which has the effect of preventing the corrugated cardboard from shifting during feeding.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a front-end feeding mechanism for a corrugated cardboard box printing machine, including a printing machine, a support platform fixedly connected to the outside of the printing machine, a slide rail opened inside the support platform, two limiting plates slidably connected inside the slide rail, a track fixedly connected to the outer wall of the printing machine, a moving plate slidably connected inside the track, a rotating rod rotatably connected inside the moving plate, a first gear fixedly connected to one end of the rotating rod, a second gear rotatably connected inside the moving plate, the first gear and the second gear meshing, a screw fixedly connected to the center of the second gear, a sleeve threadedly connected to the outside of the screw, top rods fixedly connected to both sides of the sleeve, and a placement platform fixedly connected to the top of the top rod.

[0007] By adopting the above technical solution, two mutually symmetrical limiting plates are set outside the feed inlet of the printing machine. By displacing the two limiting plates inside the slide, the distance between the two limiting plates can be adjusted. The operator adjusts the gap between the two limiting plates according to the length of the corrugated cardboard, so that the corrugated cardboard passes through the gap between the two limiting plates, preventing the corrugated cardboard from deviating during the feeding process. The moving plate moves along the track to place the corrugated cardboard above the placement table. The moving plate drives the corrugated cardboard on the placement table to move, so that the corrugated cardboard is close to the feed inlet. The rotating rod is rotated, so that the rotating rod drives the first gear and the second gear to mesh. The second gear drives the screw to rotate. During this process, the sleeve drives the top rod and the placement table to rise and fall, so that the corrugated cardboard on the placement table is kept horizontal with the feed inlet. This not only prevents the corrugated cardboard from deviating during the feeding process, but also facilitates the feeding of the corrugated cardboard into the inside of the feed inlet by adjusting the position of the placement table.

[0008] A further feature of this invention is that the other end of the rotating rod extends through the outside of the moving plate, and a rocker arm is fixedly connected to the other end of the rotating rod.

[0009] By adopting the above technical solution, it is relatively convenient to rotate the lever by hand.

[0010] A further feature of this invention is that the two limiting plates are symmetrical to each other, and a rubber layer is fixedly connected to the inner side of each of the two limiting plates, with a notch opened on the inner side of the rubber layer.

[0011] By adopting the above technical solution, two rubber layers are set inside the two limiting plates, and the corrugated cardboard passes through the inside of the notch during the feeding process.

[0012] A further feature of this invention is that the placement platform is internally connected to a roller, and the number of rollers is multiple.

[0013] By adopting the above technical solution, when feeding corrugated cardboard, the roller contacts the corrugated cardboard, and the rotation of the roller improves the smoothness of feeding.

[0014] A further feature of this invention is that a first sliding groove is provided on the outer side of the support platform, a first locking rod is fixedly connected to the outer side of the limiting plate, and a first locking ring is threaded onto the outer side of the first locking rod.

[0015] By adopting the above technical solution, the first locking ring is twisted, causing it to move outside the first locking rod. The first locking rod moves laterally inside the first sliding groove and contacts the outer wall of the support platform, thereby locking and fixing the first locking rod and the limiting plate.

[0016] A further feature of this invention is that a second sliding groove is provided on the outer side of the track, a second locking rod is fixedly connected to the outside of the movable plate, and a second locking ring is threadedly connected to the outside of the second locking rod.

[0017] By adopting the above technical solution, the second locking ring is twisted, causing it to move outside the second locking rod. The second locking ring moves laterally inside the second slide groove and contacts the outer wall of the track, thereby locking and fixing the second locking rod and the moving plate.

[0018] A further feature of this invention is that a support rod is fixedly connected to the bottom of the track, and a support foot is fixedly connected to the bottom of the support rod.

[0019] By adopting the above technical solution, the support rod and the support leg support the bottom of the track.

[0020] A further feature of this invention is that an anti-slip pad is fixedly connected to the bottom of the support leg, and anti-slip particles are fixedly connected to the bottom of the anti-slip pad.

[0021] By adopting the above technical solutions, the anti-slip mat and anti-slip particles provide friction and improve support stability.

[0022] A further feature of this invention is that the printing press has an inlet.

[0023] By adopting the above technical solution, corrugated cardboard enters the interior of the printing press through the feed inlet, and the corrugated cardboard comes into contact with the ink rollers inside the printing press.

[0024] A further feature of this invention is that a protective sleeve is fixedly connected to the outside of the rocker arm, and the outer surface of the protective sleeve is provided with anti-slip texture.

[0025] By adopting the above technical solution, the sheath wraps around the outside of the joystick, and the anti-slip texture increases friction to prevent slipping out of the hand.

[0026] The beneficial effects of this utility model are:

[0027] 1. This utility model, through the arrangement of a printing machine, support table, slide rail, limiting plate, track, moving plate, rotating rod, first gear, second gear, screw, sleeve, top rod, and placement table, features two symmetrical limiting plates positioned outside the feed inlet of the printing machine. By displacing the two limiting plates within the slide rail, the distance between them can be adjusted. The operator adjusts the gap between the two limiting plates according to the length of the corrugated cardboard, ensuring the cardboard passes through the gap and preventing deviation during feeding. The moving plate is connected to the track... The corrugated cardboard is moved to a position on the placement platform. The moving plate moves the corrugated cardboard on the placement platform closer to the feed inlet. The rotating rod is rotated, causing the first gear and the second gear to mesh. The second gear drives the screw to rotate. During this process, the sleeve moves the top rod and the placement platform up and down, thus keeping the corrugated cardboard on the placement platform level with the feed inlet. This not only prevents the corrugated cardboard from shifting during feeding, but also makes it easier to feed the corrugated cardboard into the feed inlet by adjusting the position of the placement platform.

[0028] 2. In this utility model, the rubber layer, the notch and the roller are arranged so that the two rubber layers are set inside the two limiting plates and the corrugated cardboard passes through the inside of the notch during the feeding process. When the corrugated cardboard is pushed to feed, the roller contacts the corrugated cardboard and the rotation of the roller improves the feeding smoothness. Attached Figure Description

[0035] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0036] A front-end feeding mechanism for a corrugated cardboard box printing machine includes the following specific embodiments:

[0037] Example 1:

[0038] Reference Figure 1-4 The printing machine 1 is externally fixedly connected to a support platform 2. The support platform 2 has a slide rail 3 inside. Two limiting plates 4 are slidably connected inside the slide rail 3. The outer wall of the printing machine 1 is fixedly connected to a track 5. The track 5 is slidably connected to a moving plate 6. The moving plate 6 is rotatably connected to a rotating rod 7. One end of the rotating rod 7 is fixedly connected to a first gear 8. The moving plate 6 is rotatably connected to a second gear 9. The first gear 8 and the second gear 9 mesh. The center of the second gear 9 is fixedly connected to a screw 10. The screw 10 is threadedly connected to a sleeve 11. Both sides of the sleeve 11 are fixedly connected to a top rod 12. The top of the top rod 12 is fixedly connected to a placement platform 13.

[0039] Furthermore, the other end of the rotating rod 7 extends through the outside of the movable plate 6, and a rocker arm 14 is fixedly connected to the other end of the rotating rod 7. A protective sleeve is fixedly connected to the outside of the rocker arm 14, and anti-slip texture is provided on the outside of the protective sleeve.

[0040] Specifically, two symmetrical limiting plates 4 are set outside the feed inlet 26 of the printing machine 1. By moving the two limiting plates 4 inside the slide 3, the distance between the two limiting plates 4 can be adjusted. The operator adjusts the gap between the two limiting plates 4 according to the length of the corrugated cardboard, so that the corrugated cardboard passes through the gap between the two limiting plates 4, preventing the corrugated cardboard from shifting during the feeding process. The moving plate 6 moves through the track 5 to place the corrugated cardboard above the placement table 13. The moving plate 6 drives the corrugated cardboard on the placement table 13 to move, so that the corrugated cardboard is close to the feed inlet 26. Rotating the lever 7 and holding the rocker arm 14 makes it convenient to rotate the lever 7, which drives the first gear 8 and the second gear 9 to mesh. The second gear 9 drives the screw 10 to rotate. During this process, the sleeve 11 drives the top rod 12 and the placement platform 13 to rise and fall, thereby keeping the corrugated cardboard on the placement platform 13 horizontal with the feed inlet. This not only prevents the corrugated cardboard from shifting during feeding, but also makes it easier to feed the corrugated cardboard into the feed inlet 26 by adjusting the position of the placement platform 13. The sleeve wraps around the outside of the rocker arm 14 and increases friction through anti-slip texture to prevent slippage.

[0041] Example 2:

[0042] Reference Figure 1 and Figure 4 Two limiting plates 4 are symmetrical to each other, and a rubber layer 15 is fixedly connected to the inner side of each limiting plate 4. A notch 16 is opened on the inner side of the rubber layer 15. A roller 17 is rotatably connected inside the placement platform 13. There are multiple rollers 17.

[0043] Specifically, two rubber layers 15 are set inside the two limiting plates 4, and the corrugated cardboard passes through the inside of the notch 16 during the feeding process. When pushing the corrugated cardboard, the roller 17 contacts the corrugated cardboard, and the smoothness of feeding is improved by the rotation of the roller 17.

[0044] Example 3:

[0045] Reference Figure 1 The support platform 2 has a first sliding groove 18 on its outer side, the limiting plate 4 has a first locking rod 19 fixedly connected to its outer side, the first locking rod 19 has a first locking ring 20 connected to its outer thread, the track 5 has a second sliding groove 21 on its outer side, the moving plate 6 has a second locking rod 22 fixedly connected to its outer side, the second locking rod 22 has a second locking ring 23 connected to its outer thread, the track 5 has a support rod 24 fixedly connected to its bottom, the support rod 24 has a support foot 25 fixedly connected to its bottom, the support foot 25 has an anti-slip pad fixedly connected to its bottom, the anti-slip pad has anti-slip particles fixedly connected to its bottom, and the printing machine 1 has a feed inlet 26 inside.

[0046] Specifically, twisting the first locking ring 20 causes it to move outside the first locking rod 19. The first locking rod 19 then moves laterally inside the first slide groove 18 and contacts the outer wall of the support platform 2, thereby locking and fixing the first locking rod 19 and the limiting plate 4. Twisting the second locking ring 23 causes it to move outside the second locking rod 22. The second locking ring 23 moves laterally inside the second slide groove 21 and contacts the outer wall of the track 5, thereby locking and fixing the second locking rod 22 and the moving plate 6. The support rod 24 and the support foot 25 support the bottom of the track 5. The anti-slip pad and anti-slip particles provide friction and improve the stability of the support. The corrugated cardboard enters the printing press 1 through the feed port 26 and contacts the ink roller inside the printing press 1.

[0047] In this invention, two symmetrical limiting plates 4 are positioned outside the feed inlet 26 of the printing machine 1. By displacing the two limiting plates 4 within the slide rail 3, the distance between them can be adjusted. The operator adjusts the gap between the two limiting plates 4 according to the length of the corrugated cardboard, allowing the cardboard to pass through the gap and preventing it from shifting during feeding. The moving plate 6 is displaced via the track 5, placing the corrugated cardboard above the placement table 13. The moving plate 6 moves the cardboard on the placement table 13 closer to the feed inlet 26. The rotating rod 7 drives the first gear. 8 engages with the second gear 9, which drives the screw 10 to rotate. During this process, the sleeve 11 drives the top rod 12 and the placement platform 13 to rise and fall, thereby keeping the corrugated cardboard on the placement platform 13 horizontal with the feed inlet. This prevents the corrugated cardboard from shifting during feeding and, by adjusting the position of the placement platform 13, facilitates feeding the corrugated cardboard into the feed inlet 26. Two rubber layers 15 are set inside the two limiting plates 4, and the corrugated cardboard passes through the notch 16 during feeding. When pushing the corrugated cardboard, the roller 17 contacts the corrugated cardboard, and the rotation of the roller 17 improves the smoothness of feeding.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
