[0010] Based on the above technical solution, the present invention can be further improved as follows.
[0011] Furthermore, both limiting plates are inclined toward their opposite sides, and a buffer pad is provided on the left side of the baffle.
[0012] The beneficial effect of adopting the above-mentioned further solution is that the two limiting plates are inclined towards their opposite sides, which can guide the cardboard to move towards the center, keeping it in a centered position on the conveyor belt and preventing the cardboard from shifting during transportation. The buffer pad set on the left side of the baffle can effectively reduce the collision between the cardboard and the baffle, preventing damage to the cardboard.
[0013] Furthermore, the reciprocating device includes a motor fixedly connected to the outside of the protective frame, a reciprocating lead screw rotatably connected to the inside of the protective frame and fixedly connected to the outside of the output shaft of the motor, and a transmission block fixedly connected to the mounting bracket and driven to the outside of the reciprocating lead screw.

[0017] Furthermore, the limiting frame has two clearance slots inside, and the two push plates pass through and extend into the interior of the two clearance slots respectively.
[0018] The advantage of adopting the above-mentioned further solution is that the clearance groove inside the limiting frame provides movement space for the pusher plate, ensuring that the pusher plate can smoothly push the cardboard into the feed inlet of the printing press.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] In the embodiments, by Figure 1-4 This invention discloses a feeding device for water-based ink printing machine processing. The device includes a first support frame 1, a conveyor belt 2 at its top, two symmetrically arranged limiting plates 3 fixedly connected to the top of the first support frame 1, a baffle 4 fixedly connected to the top of the first support frame 1, a second support frame 5 on the right side of the first support frame 1, a protective frame 6 fixedly connected to the top of the second support frame 5, a reciprocating device 7 inside the protective frame 6, a mounting frame 8 fixedly connected to the outside of the reciprocating device 7, and a first... An electric push rod 9 is provided. A mounting plate 10 is fixedly connected to the outside of the first electric push rod 9. A number of vacuum suction cups 11 are fixedly connected to the outside of the mounting plate 10. A third support frame 12 is provided on the right side of the second support frame 5. A water-based ink printing machine 13 is fixedly connected to the top of the third support frame 12. A feed port is provided on the left side of the water-based ink printing machine 13. A limiting frame 14 located to the left of the feed port is fixedly connected to the top of the third support frame 12. A second electric push rod 15 is fixedly connected to the bottom of the limiting frame 14. A push plate 16 is fixedly connected to the outside of the second electric push rod 15.
[0028] Both limiting plates 3 are inclined to their opposite sides, and a buffer pad is provided on the left side of the baffle 4.
[0029] In this embodiment, during actual use, when the cardboard is conveyed on the conveyor belt 2, it may deviate due to its shape or vibration during the conveying process. The inclined limiting plate 3 can automatically guide the cardboard back to the middle position, ensuring that the cardboard can be accurately adsorbed by the vacuum suction cup and conveyed to the printing machine feed port. The buffer pad can protect the cardboard from damage when it comes into contact with the baffle 4, improving the integrity of the cardboard and the printing quality.
[0030] The reciprocating device 7 includes a motor 71 fixedly connected to the outside of the protective frame 6. The output shaft of the motor 71 is fixedly connected to a reciprocating lead screw 72 rotatably connected to the inside of the protective frame 6. The reciprocating lead screw 72 is driven by a transmission block 73 fixedly connected to the mounting bracket 8.
[0031] In this embodiment, during actual use, during the feeding process of the water-based ink printing machine, the cardboard needs to be precisely moved from the conveyor belt 2 to the inlet of the printing machine. The reciprocating device 7 can precisely adjust the position of the vacuum suction cup 11 according to the position of the cardboard and the requirements of the printing machine to ensure that the cardboard can be accurately suctioned and transported. That is, the reciprocating screw 72 is driven to rotate by the motor 71, and then the transmission block 73 drives the mounting frame 8 to move. This precise motion control is crucial for improving feeding efficiency and printing quality.
[0032] The protective frame 6 has two sliding rods 17 fixedly connected inside, and the mounting bracket 8 has sliding sleeves 18 fixedly connected to the two sliding rods 17 respectively.
[0033] In this embodiment, during actual use, the vacuum suction cup 11 needs to be in a stable motion state to accurately adsorb and transport the cardboard. The cooperation between the sliding rod 17 and the sliding sleeve 18 can effectively reduce the shaking and offset of the mounting frame 8 during movement, improving the stability and reliability of the entire feeding device. This is of great significance for improving production efficiency and reducing the defect rate. At the same time, dustproof telescopic protective sleeves are provided on the outer sides of the sliding rod 17 and the reciprocating screw 72, which can effectively prevent foreign objects such as dust, oil, and moisture from entering their interiors, thus protecting them.
[0034] The limiting frame 14 has two clearance slots inside, and the two push plates 16 pass through and extend into the two clearance slots respectively.
[0035] In this embodiment, during actual use, after the cardboard is transported to the vicinity of the printing press inlet by the vacuum suction cup, it needs to be pushed into the printing press by the push plate 16. The design of the clearance groove provides sufficient space for the movement of the push plate, ensuring that the push plate can smoothly push the cardboard into the inlet. This design can improve the efficiency and accuracy of the cardboard entering the printing press and reduce printing failures caused by poor feeding.
[0036] The limiting frame 14 is internally connected to a number of conveying rollers 19 that are symmetrically distributed front and back, and the top surfaces of the multiple conveying rollers 19 are flush with the feed inlet of the water-based ink printing machine 13.
[0037] In this embodiment, during actual use, as the cardboard is pushed into the printing press feed inlet, the conveying roller 19 can provide additional support and conveying power to ensure that the cardboard remains flat when entering the printing press. This design can effectively reduce the failure of the cardboard during the feeding process and improve the operating efficiency and printing quality of the printing press.
[0038] Working principle:
[0039] First, the cardboard to be printed is placed on the conveyor belt 2 at the top of the first support frame 1. The conveyor belt 2 starts and transports the cardboard to the right. During the transport process, the cardboard is guided by two inclined limiting plates 3, keeping it in the middle position of the conveyor belt 2 to prevent deviation. When the cardboard reaches the end of the conveyor belt 2, the reciprocating device 7 at the top of the second support frame 5 starts to work. The motor 71 drives the reciprocating screw 72 to rotate, which drives the mounting frame 8 to move horizontally back and forth within the protective frame 6 through the transmission block 73. When the vacuum suction cup 11 on the mounting frame 8 moves above the cardboard, the vacuum system is activated to suck up the cardboard and move it towards the edge. The repeater 7 continues to operate, moving the vacuum suction cup 11 with the cardboard attached horizontally to a designated position above the third support frame 12. When the vacuum suction cup 11 transports the cardboard above the limiting frame 14, the vacuum system stops working, and the cardboard falls onto the conveying roller 19 inside the limiting frame 14. The second electric push rod 15 at the top of the third support frame 12 is activated, pushing the push plate 16 to push the cardboard into the printing press inlet. As the cardboard moves, the conveying roller 19 begins to rotate, assisting the cardboard to move towards the printing press inlet. At the inlet, the cardboard is further transported by the conveying mechanism inside the printing press and enters the printing press for printing.
[0040] It should be noted that both the motor and the electric linear actuator are used in conjunction with encoders and motor controllers, or with PLCs or professional motion controllers. Control programs are written to centrally control the motor or electric linear actuator, monitor the motor's rotation angle and speed in real time, and convert this information into electrical signals to feed back to the controller, so as to achieve precise control of the motor and electric linear actuator.
[0041] Simultaneously, the vacuum suction cups should be selected with appropriate shapes (such as round, oval, or rectangular) and sizes to match the size and shape of the cardboard. Larger suction cups can provide a larger adsorption area, but require a higher vacuum to maintain the adsorption force. Suction cups should be made of materials with good elasticity and sealing properties (such as silicone or rubber) to adapt to the unevenness of the cardboard surface and improve the sealing performance. At the same time, multiple suction cups should be arranged reasonably according to the size and weight of the cardboard to distribute the adsorption force and avoid failure due to excessive load on a single suction cup.
[0042] Furthermore, the cardboard surface should be as flat as possible, without obvious unevenness or wrinkles. A flat surface can better fit with the vacuum suction cup and form a good seal. The cardboard surface should be clean and free of dust, oil, moisture or other impurities. These impurities will damage the seal between the suction cup and the cardboard, resulting in insufficient adsorption force. The cardboard should have a certain thickness and strength, and the material of the cardboard should have a certain degree of elasticity and toughness to avoid deformation or damage during the adsorption process.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
