[0004] The automatic feeding and printing device for packaging box paperboard printing has the following disadvantages:

[0005] 1. The distance of the printing plate descending each time is equal.

[0051] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0052] The present invention provides the following preferred embodiments:

[0053] Example 1:

[0054] like Figures 1-12 As shown, an automatic feeding device for a hang tag printing equipment includes a conveyor 11, a mounting frame 12, a printing plate 14, a dipping mechanism, a feeding mechanism, and a coating mechanism. The mounting frame 12 is fixedly installed on the top of the conveyor 11, and mounting plates 15 are symmetrically fixed on both sides of the top of the conveyor 11. The printing plate 14 is located above the conveyor 11 and on one side of the mounting frame 12.

[0055] The dipping mechanism includes a printing material box 13 and a flipping assembly for driving the printing plate 14 to flip. The printing material box 13 is fixedly installed on one side of the top of the mounting frame 12 and is located between two mounting plates 15. The flipping assembly is installed between the printing plate 14 and the conveyor 11.

[0056] The flipping component is used to flip the printing plate 14. In the initial state, the printing plate 14 is located above the hang tag on the conveyor 11 and is set horizontally. Under the action of the flipping component, the printing plate 14 can be flipped to a vertical state, and the printing plate 14 and the printing material box 13 are in contact, so that the ink on the printing material box 13 can be dipped, which can achieve the effect of feeding material and facilitate the subsequent printing of the next hang tag.

[0057] The feeding mechanism includes an ink storage tank 39, a storage cylinder 37, an extrusion assembly and a first transmission assembly. The ink storage tank 39 and the storage cylinder 37 are fixedly installed at the top end of the mounting frame 12. One end of the storage cylinder 37 is connected with a hose 36. The bottom end of the ink storage tank 39 is connected with the end of the storage cylinder 37 close to the hose 36 through a feeding pipe 40, that is, the ink in the ink storage tank 39 can enter the inside of the storage cylinder 37 through the feeding pipe 40 for storage. The extrusion mechanism is installed in the inside of the storage cylinder 37. The extrusion assembly can extrude the ink stored in the inside of the storage cylinder 37, thereby facilitating subsequent feeding of the ink. The first transmission assembly is located at the end of the extrusion mechanism away from the hose 36. The first transmission assembly can drive the extrusion assembly to move. When the extrusion assembly moves towards the side close to the hose 36, the ink stored in the inside of the storage cylinder 37 can be extruded to realize feeding. When the extrusion assembly moves away from the side close to the hose 36 under the action of the first transmission assembly, the ink in the inside of the ink storage tank 39 can be transported to the inside of the storage cylinder 37 for storage under the action of negative pressure. In order to facilitate feeding next time and the stroke of the extrusion assembly each time is consistent, the amount of ink extracted each time is consistent, which can ensure quantitative feeding and enable a certain amount of ink to be added to the printing box 13 each time, thereby enabling the printing plate 14 to dip a certain amount of ink each time, ensuring the uniformity of the printing color on the hang tag during continuous printing and avoiding inconsistency of the printing color on the front and back hang tags.

[0058] The smearing mechanism includes a uniformizing roller 29, a feeding assembly, a lifting assembly and a rotating assembly. The uniformizing roller 29 is located at the side of the printing box 13 close to the printing plate 14. Specifically, the uniformizing roller 29 is attached to the surface of the printing box 13, which facilitates subsequent transmission of the ink to the printing box 13. The feeding assembly is located between the hose 36 and the uniformizing roller 29. The feeding assembly can transport the ink in the inside of the storage cylinder 37 to the uniformizing roller 29 through the hose 36, thereby facilitating subsequent transmission of the ink to the printing box 13. The lifting assembly is installed between the feeding assembly and the turnover assembly. When the turnover assembly works, the lifting assembly can drive the uniformizing roller 29 and the feeding assembly to lift, so that the surface of the printing box 13 can be uniformly inked. The end of the first transmission assembly away from the extrusion assembly is connected with the lifting assembly. When the lifting assembly works, the first transmission assembly can drive the extrusion assembly to work, so that the extrusion assembly can realize linkage effect, that is, when the lifting assembly drives the uniformizing roller 29 to rise, the extrusion assembly can extrude the ink from the storage cylinder 37, and the ink is uniformly transmitted to the surface of the printing box 13 at the same time that the uniformizing roller 29 rises, realizing uniform and quantitative feeding. The rotating assembly is located between the uniformizing roller 29 and one of the mounting plates 15.

[0059] In order to enable the printing plate 14 to dip the ink before printing the hang tag, a turnover assembly is designed. Figure 1 , Figure 8 and Figure 9As shown, the turnover assembly comprises a rotating disc 17, a first connecting rod 18, a second connecting rod 19, a rotating shaft 20, a first hinged rod 21, a hinged block 22, a rotating rod 24, a connecting block 25 and a limiting rod 26;

[0060] The rotating shaft 20 is rotatably arranged on one of the mounting plates 15, and the two ends of the rotating shaft 20 are fixedly connected with one end of the first connecting rod 18 and one end of the second connecting rod 19 respectively, and the rotating shaft 20, the first connecting rod 18 and the second connecting rod 19 are fixedly connected with each other. The hinged block 22 is fixedly arranged on one side of the printing plate 14, and the other end of the first connecting rod 18 is hingedly connected with the hinged block 22. The rotating disc 17 is rotatably arranged on one side of the conveyor 11, and the other end of the second connecting rod 19 is hingedly connected with one end of the first hinged rod 21. The other end of the first hinged rod 21 is rotatably arranged at the edge of the surface of the rotating disc 17. The motor 16 is fixedly arranged on the conveyor 11, and the output end of the motor 16 is fixedly connected with the rotating disc 17, that is, the motor 16 can drive the rotating disc 17 to rotate when the motor 16 works.

[0061] The vertical plate 23 is fixedly arranged at the top end of the conveyor 11, and the rotating rod 24 is rotatably arranged on the vertical plate 23. One end of the rotating rod 24 is fixedly connected with the connecting block 25, and the middle part of the connecting block 25 is connected with the limiting rod 26 through a sliding bearing. The limiting rod 26 is slidably arranged in the connecting block 25, and the bottom end of the limiting rod 26 is hingedly connected with the top end of the printing plate 14.

[0062] In the initial state, the printing plate 14 is arranged horizontally. When the hanging plate on the conveyor 11 moves below the printing plate 14, the conveyor 11 stops working to avoid the hanging plate moving with the conveyor 11.

[0063] Then the motor 16 is controlled to work, and the motor 16 drives the rotating disc 17 to rotate. Under the action of the first hinged rod 21, the second connecting rod 19, the rotating shaft 20 and the first connecting rod 18 can rotate by 90 degrees around the axis of the rotating shaft 20. In this process, since the first connecting rod 18 is hingedly connected with the hinged block 22, the first connecting rod 18 drives the printing plate 14 to turn over towards the printing material box 13 through the hinged block 22. The rotating rod 24 and the connecting block 25 rotate around the axis of the rotating rod 24, and at the same time, the printing plate 14 drives the limiting rod 26 to slide in the connecting block 25. When the first connecting rod 18 rotates from the horizontal state to the vertical state, that is, rotates by 90 degrees, the printing plate 14 is pulled to turn over to the vertical state and is located on one side of the printing material box 13 and is attached to the surface of the printing material box 13, so that the ink is uniformly dipped;

[0064] After the ink is dipped, the control motor 16 drives the rotating disc 17 to rotate reversely, and under the action of the first hinged rod 21, the second connecting rod 19, the rotating shaft 20 and the first connecting rod 18 are driven to rotate reversely by 90 degrees around the axis of the rotating shaft 20, so that the printing plate 14 is reset to the horizontal state, the printing of the hanging tag above the conveyor 11 is realized, and the printing of the hanging tag at one time is realized.

[0065] In order to facilitate the uniform transmission of the extruded ink to the printing cartridge 13, and to achieve the purpose that the printing plate 14 can dip the ink uniformly, a feeding assembly is designed, as shown in Figure 7 and Figure 10 The feeding assembly comprises a U-shaped frame 27, a transmission roller 28, an L-shaped pipe 34 and a plurality of discharge nozzles 35.

[0066] The U-shaped frame 27 is located on one side of the printing cartridge 13, both ends of the uniformizing roller 29 are rotatably arranged on the U-shaped frame 27, the transmission roller 28 is located above the uniformizing roller 29 and is attached to the uniformizing roller 29, so as to facilitate the transmission of the ink on the transmission roller 28 to the uniformizing roller 29, both ends of the transmission roller 28 are rotatably arranged on the U-shaped frame 27, the L-shaped pipe 34 is fixedly installed at the top end of the U-shaped frame 27, one end of the L-shaped pipe 34 is connected with the soft tube 36 away from the ink storage cylinder 37, and the plurality of discharge nozzles 35 are equidistantly arranged above the transmission roller 28 and are connected with the L-shaped pipe 34.

[0067] In use, the ink is transported to the inside of the L-shaped pipe 34 through the soft tube 36 by the extrusion assembly, and flows out to the surface of the transmission roller 28 through the plurality of discharge nozzles 35. Since the transmission roller 28 and the uniformizing roller 29 are attached, when the U-shaped frame 27 moves with the lifting assembly, the uniformizing roller 29 can rotate under the action of the rotating assembly, at this time, the transmission roller 28 is driven to rotate, and the ink on the transmission roller 28 can be transmitted to the uniformizing roller 29. Since the uniformizing roller 29 and the surface of the printing cartridge 13 are attached, the ink on the uniformizing roller 29 can be transmitted to the printing cartridge 13, achieving the effect of uniform feeding, so that a certain amount of ink can be evenly laid on the surface of the printing cartridge 13, to facilitate the subsequent dipping of the printing plate 14.

[0068] The surface of each mounting plate 15 is provided with a strip-shaped groove 30, and each strip-shaped groove 30 is slidably connected with a sliding block 31. Each sliding block 31 is fixedly installed at the end of the U-shaped frame 27, and the sliding block 31 is slidably arranged in the strip-shaped groove 30, and can play a guiding role when the U-shaped frame 27 moves.

[0069] In order to make the uniformizing roller 29 move on the surface of the printing cartridge 13 and achieve the effect of uniform transmission of the ink, a lifting assembly is designed, as shown in Figure 1 and Figure 10As shown, the lifting assembly comprises an inclined frame 48, a guide rod 49, a second hinged rod 51, a third connecting rod 52 and four sliding rods 50;

[0070] Each two sliding rods 50 are fixedly installed on one side of the inclined frame 48, and each sliding rod 50 is slidingly arranged on the surface of one installation plate 15, i.e. the sliding rod 50 can play a guiding role when sliding on the inclined frame 48. The guide rod 49 is inserted into the interior of the inclined frame 48, and the guide rod 49 can slide in the interior of the inclined frame 48, and one end of the guide rod 49 is fixedly connected with one sliding block 31;

[0071] The end of the rotating rod 24, which is away from the connecting block 25, penetrates through the vertical plate 23 and is fixedly connected with one end of the third connecting rod 52, and the other end of the third connecting rod 52 is hingedly connected with one end of the second hinged rod 51, and the other end of the second hinged rod 51 is hingedly connected with the surface of the inclined frame 48;

[0072] When the printing plate 14 is flipped to one side of the printing cartridge 13, the printing plate 14 drives the rotating rod 24 to rotate counterclockwise (refer to Figure 8 ) around the axis of the rotating rod 24, and the rotating rod 24 can drive the third connecting rod 52 to rotate synchronously, and the third connecting rod 52 can drive the inclined frame 48 to move along the length of the sliding rod 50 towards the side away from the third connecting rod 52 under the action of the second hinged rod 51. Since the inclined frame 48 is arranged in an inclined manner and the guide rod 49 is inserted into the interior of the inclined frame 48, the inclined frame 48 can drive the guide rod 49 to move upwards when the inclined frame 48 moves, thereby driving the U-shaped frame 27 to move upwards;

[0073] That is, during the process of flipping the printing plate 14 to one side of the printing cartridge 13, the material roller 29 can move upwards on the surface of the printing cartridge 13, thereby achieving the transmission of ink to the printing cartridge 13 before the printing plate 14 dips. It should be noted that, in actual use, when the inclined frame 48 moves to the farthest position, the U-shaped frame 27 can be driven to move above the printing cartridge 13, thereby playing a role of avoiding affecting the docking of the printing cartridge 13 and the printing plate 14;

[0074] After the printing plate 14 dips ink from the printing cartridge 13, the rotating rod 24 reversely rotates, thereby driving the inclined frame 48 to reversely move, and the U-shaped frame 27 and the material roller 29 can be driven to move downwards to reset, thereby facilitating the transmission of ink in the next time.

[0075] In order to ensure that the ink can be quantitatively transmitted to the feeding assembly, an extrusion assembly is designed, as shown in Figure 3 and Figure 11As shown, the extrusion assembly comprises a push plate 41, a push rod 42 and a through hole 59, the push plate 41 is slidingly arranged in the inside of the storage cylinder 37, the push plate 41 and the storage cylinder 37 are in sealing sliding connection, the push rod 42 is inserted into the end of the storage cylinder 37 away from the hose 36, the push rod 42 can slide on the storage cylinder 37, one end of the push rod 42 is fixedly connected with the push plate 41, the through hole 59 is arranged on the surface of the end of the storage cylinder 37 away from the hose 36, the arrangement of the through hole 59 can ensure the balance of the pressure in the inside of the storage cylinder 37 when the push plate 41 slides, the hose 36 and the dispensing pipe 40 are both provided with a one-way valve 60 at the end close to the storage cylinder 37, specifically, the one-way valve 60 on the hose 36 allows the ink to move from the storage cylinder 37 to the hose 36, and the one-way valve 60 on the dispensing pipe 40 allows the ink to move from the dispensing pipe 40 to the storage cylinder 37;

[0076] In use, the first transmission assembly can drive the push rod 42 to move, in the initial state, the push plate 41 is located on the side away from the hose 36, and a certain amount of ink is pre-stored in the inside of the storage cylinder 37, when the first transmission assembly works, it can drive the push rod 42 to move towards the side close to the hose 36, the push rod 42 drives the push plate 41 to move, and the ink in the inside of the storage cylinder 37 is extruded to the feeding assembly, so as to uniformly transfer the ink to the printing cartridge 13 subsequently;
