Description

Technical Field

[0001] This utility model relates to a paperboard printing feeding device, specifically an automatic feeding device for paperboard printing. Background Technology

[0002] Paperboard is a thick material made of pulp, which is usually thicker and harder than ordinary paper, and has higher strength and durability. It is widely used in packaging, printing and manufacturing. Paperboard printing machines are devices specifically designed for printing on paperboard and are widely used in packaging, advertising and publishing industries. The process of paperboard printing is to transfer ink to the surface of paperboard through a printing press to form the desired pattern or text. It usually includes steps such as paper feeding, printing, drying and paper collection.

[0003] The feeding process in cardboard printing is the first step in neatly feeding the cardboard into the printing press to ensure smooth printing. Common feeding devices for cardboard printing include vacuum suction cup feeding devices, paper feeding roller feeding devices, and stacking feeding devices. However, these devices are complex, require significant investment, and necessitate regular maintenance. Furthermore, during the cardboard printing and production process, adhesive or oil on the cardboard surface can cause adjacent cards to stick together, resulting in multiple cards being fed at once. Since the cardboard is stacked in a box before feeding, the number and stack height of the cards change as they are fed. This necessitates manual adjustment of the feeding device's pressure, speed, and suction parameters based on the stack height, affecting the stability of the feeding device's gripping or conveying of the cardboard, and consequently impacting printing quality and production efficiency.

[0004] In the existing paperboard printing and production process, when there is glue or oil on the paperboard surface, adjacent paperboards may stick together, which can easily lead to multiple paperboards being fed in at once. Furthermore, when the paperboard stack changes during the feeding process, manual adjustments to the pressure, speed, and suction parameters of the feeding device are required based on the stack height. This affects the stability of the feeding device in picking up or conveying paperboard, and consequently affects printing quality and production efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic feeding device for cardboard printing, which solves the problems mentioned in the background art, such as when there is glue or oil on the surface of the cardboard, adjacent cardboard sheets will stick together, which can easily lead to multiple cardboard sheets being fed in at one time. In addition, when the cardboard stacking changes during the feeding process, manual adjustment of the feeding device's pressure, speed and suction parameters is required at any time according to the adjustment of the cardboard stacking height, which affects the stability of the feeding device in picking up or conveying cardboard, and thus affects the printing quality and production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic feeding device for paperboard printing includes a storage box, a conveyor belt for conveying paperboard and a feeding mechanism for feeding paperboard are provided on one side of the storage box, and a friction mechanism for separating paperboard is provided on the storage box.

[0008] The feeding mechanism includes a driving mechanism and a lifting mechanism for lifting the cardboard, wherein the driving mechanism and the lifting mechanism cooperate vertically.

[0009] The friction mechanism includes four first elastic shrink blocks installed on both sides of the storage box, and two inclined blocks disposed on both sides of the storage box. Two of the inclined blocks are slidably disposed between the four first elastic shrink blocks. Multiple sets of friction wheels for frictional separation of the cardboard are rotatably installed inside the inclined blocks.

[0010] The automatic feeding device for paperboard printing as described above includes a lifting mechanism comprising a sliding block slidably mounted on the bottom of a storage box and a tray fixed on the top of the sliding block. A second elastic shrink block is slidably mounted on the bottom of the sliding block. A shaft and a rotating arm slidably mounted on the shaft are rotatably mounted on the bottom of the storage box.

[0011] As described above, the automatic feeding device for paperboard printing includes two symmetrically arranged grooves on the rotating arm and a rotating shaft slidably installed in the grooves. A sliding frame and a lifting plate slidably installed on the sliding frame are installed on one side of the storage box. The two rotating shafts are respectively rotatably arranged at the bottom of the second elastic shrink block and the lifting plate.

[0012] The automatic feeding device for cardboard printing as described above: the driving mechanism includes a supporting steel frame disposed on one side of the storage box and a sliding cavity disposed on the supporting steel frame, the sliding cavity being provided with an arc-shaped track and an electric slider slidably mounted on the arc-shaped track.

[0013] The automatic feeding device for cardboard printing as described above: the driving mechanism further includes a transverse support disposed on the top of the supporting steel frame and a movable frame slidably mounted on the transverse support, wherein a fixing element is slidably fitted on the movable frame.

[0014] As described above, the automatic feeding device for cardboard printing includes a drive mechanism that further comprises a connecting frame disposed at the bottom of the fixing member and a pressing frame installed at the bottom of the connecting frame. The pressing frame cooperates with the lifting plate. A connecting shaft is provided between the connecting frame and the electric slider. A vacuum suction cup is connected to one side of the connecting frame and an extrusion block is installed on both sides of the vacuum suction cup. The two extrusion blocks cooperate with two inclined blocks respectively.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By using a feeding mechanism and a friction mechanism on one side of the storage box, the stacked cardboard inside the storage box rises upwards when the cardboard is suctioned by a vacuum suction cup. This adaptively increases the stacking height of the cardboard during loading, facilitating the suction process. Simultaneously, it allows for the frictional separation of adjacent, adhered cardboard sheets, preventing the feeding of multiple sheets at once. This invention also achieves automated operation, ensuring smooth cardboard loading and improving loading stability. Attached Figure Description

[0030] Please see Figures 1-11 As an embodiment of the present utility model, the automatic feeding device for paperboard printing includes a storage box 1. A conveyor belt 2 for conveying paperboard and a feeding mechanism for feeding paperboard are provided on one side of the storage box 1. A friction mechanism for separating paperboard is provided on the storage box 1.

[0031] The feeding mechanism includes a driving mechanism and a lifting mechanism for lifting the cardboard, and the driving mechanism and the lifting mechanism cooperate vertically.

[0032] In this embodiment, the storage box 1 pre-stores the cardboard, the conveyor belt 2 conveys the cardboard, the feeding mechanism picks up the cardboard in the storage box 1 and sends the cardboard picked up in the storage box 1 onto the conveyor belt 2, the friction mechanism can rub and separate the cardboard, and the lifting mechanism lifts the cardboard upwards when picking it up, which facilitates the picking up of the cardboard.

[0033] In addition, before printing, the cardboard is stacked in the storage box 1, and the cardboard in the storage box 1 is conveyed to the conveyor belt 2 by the feeding mechanism. The conveyor belt 2 then feeds the cardboard into the printing equipment for printing. When the cardboard is being picked up, the lifting mechanism lifts the cardboard upwards, which can adapt to increasing the stacking height of the cardboard and facilitate the picking up of the cardboard. The friction mechanism can separate adjacent cardboards by friction, avoiding the feeding of multiple cardboard sheets at one time.

[0034] As a further embodiment of this utility model, the friction mechanism includes four first elastic shrink blocks 4 installed on both sides of the storage box 1, and inclined blocks 5 disposed on both sides of the storage box 1. Two of the inclined blocks 5 are slidably disposed between the four first elastic shrink blocks 4, and multiple sets of friction wheels 6 for frictional separation of the cardboard are rotatably installed inside the inclined blocks 5.

[0035] In this embodiment, the inclined block 5 is provided with first elastic contraction blocks 4 on both sides, and a spring is provided in the first elastic contraction block 4.

The top of the inclined block 5 is designed with an inclined edge, and the inclined block 5 can move into the interior of the storage box 1.

[0036] In addition, when the inclined block 5 moves, it will drive the friction wheel 6 to move to both sides of the cardboard to rub against the cardboard, thus preventing the adjacent cardboard from sticking together.

[0037] As a further embodiment of this utility model, the lifting mechanism includes a sliding block 8 slidably mounted on the bottom of the storage box 1 and a tray 7 fixed on the top of the sliding block 8. A second elastic shrink block 9 is slidably mounted on the bottom of the sliding block 8. A shaft 12 and a rotating arm 13 slidably mounted on the shaft 12 are rotatably mounted on the bottom of the storage box 1.

[0038] In this embodiment, the sliding block 8 slides at the bottom of the storage box 1, the second elastic contraction block 9 slides dampingly at the bottom of the sliding block 8, and the shaft 12 serves as the rotation center axis of the rotating arm 13.

[0039] In addition, when the tray 7 is subjected to compressive force, the second elastic shrink block 9 will be squeezed and slid into the sliding block 8 to perform adaptive shrinkage.

[0040] As a further embodiment of this utility model, the lifting mechanism also includes two symmetrically arranged grooves 14 on the rotating arm 13 and a rotating shaft 15 slidably installed in the grooves 14. A sliding frame 10 and a lifting plate 11 slidably installed on the sliding frame 10 are installed on one side of the storage box 1. The two rotating shafts 15 are respectively rotatably arranged at the bottom of the second elastic shrink block 9 and the lifting plate 11.

[0041] In this embodiment, the rotating shaft 15 slides within the slide groove 14, and the lifting plate 11 slides within the sliding frame 10.

[0042] As a further embodiment of this utility model, the driving mechanism includes a supporting steel frame 3 disposed on one side of the storage box 1 and a sliding cavity 17 disposed on the supporting steel frame 3. The sliding cavity 17 is provided with an arc-shaped track 16 and an electric slider 18 slidably mounted on the arc-shaped track 16.

[0043] In this embodiment, the electric slider 18 slides on the arc-shaped track 16, and the sliding cavity 17 defines the sliding trajectory of the electric slider 18.

[0044] In addition, by activating the electric slider 18, the electric slider 18 is moved along the arc track 16.

[0045] As a further embodiment of this utility model, the driving mechanism also includes a transverse support 19 disposed on the top of the supporting steel frame 3 and a movable frame 20 slidably mounted on the transverse support 19, wherein a fixing member 21 is slidably fitted on the movable frame 20.

[0046] In this embodiment, the horizontal support 19 is slidably fitted with the movable frame 20, and the fixing member 21 is slidably fitted above and below the movable frame 20.

[0047] In addition, the horizontal support 19 limits the left and right movement of the movable frame 20, and the movable frame 20 limits the up and down movement of the fixing member 21.

[0048] As a further embodiment of this utility model, the driving mechanism further includes a connecting frame 22 disposed at the bottom of the fixing member 21 and a pressing frame 25 installed at the bottom of the connecting frame 22. The pressing frame 25 cooperates with the lifting plate 11. A connecting shaft is provided between the connecting frame 22 and the electric slider 18. A vacuum suction cup 23 is connected to one side of the connecting frame 22 and an extrusion block 24 installed on both sides of the vacuum suction cup 23. The two extrusion blocks 24 cooperate with two inclined blocks 5 respectively.

[0049] In this embodiment, a connecting shaft is provided between the connecting frame 22 and the electric slider 18, and the pressing frame 25 and the lifting plate 11 are in a squeezing fit. When the electric slider 18 slides, the connecting frame 22 will move accordingly. The vacuum suction cup 23 generates negative pressure through the vacuum pump to suck up the cardboard, and the squeezing blocks 24 on both sides of it are respectively in fit with the two inclined blocks 5.

[0050] Additionally, when the electric slider 18 moves the connecting frame 22, the moving frame 20 and the fixing member 21 limit the movement position of the connecting frame 22. Subsequently, when the connecting frame 22 moves to the top of the storage box 1 and moves downward, the pressing frame 25 will press the lifting plate 11 downward. The rotating shaft 15 at the bottom of the lifting plate 11 will slide in the slide groove 14. At this time, the rotating arm 13 rotates and drives the sliding block 8 and the second elastic shrink block 9 to move upward. The tray 7 moves upward, driving the cardboard stack to move upward. At the same time, the vacuum suction cup 23 moves to the top of the storage box 1 to pick up the cardboard. When the cardboard contacts the vacuum suction cup 23, the sliding block 8 and the second elastic shrink block 9 will shrink to avoid excessive force between the cardboard and the vacuum suction cup 23. At the same time, the squeezing blocks 24 on both sides of the vacuum suction cup 23 squeeze the two inclined blocks 5 respectively, causing the two inclined blocks 5 to shrink inward, thereby driving the friction wheel 6 to move to both sides of the cardboard to rub the cardboard and avoid the adhesion between adjacent cardboards.

[0051] The above embodiments are exemplary and not restrictive. Therefore, without departing from the spirit or basic characteristics of this utility model, any technical solutions that can be implemented in other specific forms are included in this utility model.
