Summary of the invention

[0005] In order to improve work efficiency, the present application provides a packaging bag printing production line.

[0006] The packaging bag printing production line provided in this application adopts the following technical solution:

[0007] A packaging bag printing production line comprises a printing production line body, a coding box is provided on one side of the printing production line body, a feeding port is provided at one end of the coding box, and a discharging port is provided at the other end, a rotating roller group for receiving packaging bags is rotatably connected in the coding box, the discharging port is communicated with an inlet of the printing production line body, a coder is provided in the coding box, a nozzle of the coder is arranged toward the packaging bags, a UV curing lamp is provided between the coder and the discharging port, and the UV curing lamp is irradiated toward the packaging bags.

[0008] By adopting the above technical solution, when in use, start the UV curing lamp, and before the packaging bag enters the printing production line body, it first enters the coding box. When the packaging bag moves under the inkjet printer, start the inkjet printer to code the packaging bag, and then cure it through the UV curing lamp. After the coding is completed, it enters the printing production line body for printing, thereby reducing the possibility of the producer taking the printed packaging bag off the winding roller and then coding it through the coder, saving production steps and improving work efficiency.

[0009] Optionally, a dust removal pipe is provided in the coding box, and the dust removal pipe is arranged along the conveying direction of the packaging bag. One end of the dust removal pipe is connected to a hair dryer. A plurality of dust blowing pipes are connected to the dust removal pipe. The plurality of dust blowing pipes are arranged along the length direction of the dust removal pipe. The lengths of the plurality of dust blowing pipes gradually increase in the direction away from the air outlet of the hair dryer. The air outlet of the dust blowing pipe is tilted to blow toward the packaging bag. The coding box is provided with an adsorption component for adsorbing dust raised in the coding box.

[0010] By adopting the above technical solution, when in use, the operator starts the hair dryer, and the hair dryer blows the gas from the air outlet to the dust removal pipe, and then blows the gas into the dust blowing pipe through the dust removal pipe, so as to blow away the dust and debris accumulated on the packaging bag to reduce the impact on the coding. Since the packaging bag has a certain width, multiple dust blowing pipes are provided, and the lengths of the multiple dust blowing pipes gradually increase, so that the dust attached to the packaging bag can be blown multiple times, thereby reducing the air volume of the hair dryer to reduce the possibility of generating dust in the coding box, and then the dust floating in the coding box is adsorbed by the adsorption component, which further collects the dust.

[0011] Optionally, the adsorption component includes dust-absorbing cotton, an active roller and a driven roller are rotatably connected in the coding box, an elastic waterproof belt is wound around the active roller and the driven roller, the dust-absorbing cotton is laid on the elastic waterproof belt, a plurality of first through holes are opened on the elastic waterproof belt, the dust-absorbing cotton is arranged opposite to the dust removal pipe, the coding box is provided with a cleaning water tank, the driven roller is located in the cleaning water tank, a first gear is sleeved on the roller shaft of the driven roller, a second shaft is rotatably provided on the cleaning water tank, a second gear is sleeved on one end of the second shaft, a first bevel gear is sleeved on the second shaft, the first gear is meshed with the second gear, the bottom wall of the cleaning water tank is rotatably connected to the stirring rod through the first shaft, a second bevel gear is sleeved on the first shaft, and the first bevel gear is meshed with the second bevel gear.

[0012] By adopting the above technical solution, when in use, the operator rotates the active roller, and with the cooperation of the elastic waterproof belt, the active roller and the driven roller rotate together, and the elastic waterproof bag drives the dust-absorbing cotton to enter the cleaning water tank, and the dust-absorbing cotton is moistened by water. When the moistened dust-absorbing cotton rotates to the side opposite to the dust blowing pipe, the dust blown off the packaging bag is absorbed by the dust-absorbing cotton, and the elastic waterproof belt with dust attached enters the cleaning water tank. At the same time, the roller shaft of the rotating driven roller drives the first gear to rotate, the first gear is meshed with the second gear, and the second gear drives the second shaft to rotate, thereby rotating the first bevel gear, and the first bevel gear is meshed with the second bevel gear, so that the first shaft rotates, and the first shaft drives the stirring rod to rotate, so that the water in the cleaning water tank rotates, which has a stirring effect on the water, and can reduce the possibility of dust entering the cleaning water tank adhering to the tank wall.

[0013] Optionally, there are multiple stirring rods, each of which is vertically provided with a support rod, and a lifting assembly for lifting the support rod is provided in the cleaning water tank, and an elastic rod is slidably connected to the support rod, one end of the elastic rod is provided with a limit plate, and the other end is provided with a knocking plate for hitting the elastic waterproof belt, and a return spring is provided on the outer sleeve of the elastic rod, one end of the return spring is connected to the limit plate, and the other end is connected to the support rod, and a first magnet is provided on the limit plate, and a first electromagnet is provided on the circumferential side wall of the side wall of the cleaning water tank, and the first electromagnet is arranged on a side of the elastic waterproof belt away from the dust removal pipe, and when the first electromagnet is energized, a repulsive force is generated between the first magnet and the first electromagnet.

[0014] By adopting the above technical solution, when in use, the rotating stirring rod drives the supporting rod to rotate, and then the supporting rod is moved upward by the lifting assembly, so that the elastic rod moves upward, and finally the first magnet and the first electromagnet are in the same horizontal plane, and the first electromagnet is energized. When the first magnet rotates to a position relative to the first electromagnet, a repulsive force is generated between the first electromagnet and the first magnet, and the repulsive force causes the limit plate to move toward the direction close to the driven roller and hit the elastic waterproof belt. Since the elastic waterproof belt facing the elastic rod is soaked in water and then adsorbed with dust, the dust forms a gray mass after meeting water, which can make the dust attached to the dust-absorbing cotton fall off, and at the same time reduce the possibility of dust generation.

[0015] Optionally, a high-density net is provided on the support rod, and a plurality of the high-density nets are enclosed to form a full circle. The high-density net is slidably matched with the inner wall of the cleaning water tank, and a sliding hole is provided on the stirring rod for the support rod to pass through. The lifting assembly includes a second electromagnet, and the second electromagnet is arranged on the bottom wall of the cleaning water tank. The second electromagnet is arranged in an arc shape, and a second magnet is provided at the bottom end of the support plate. When the second electromagnet and the second magnet are opposite to each other and the second electromagnet is energized, the repulsive force between the second electromagnet and the second magnet causes the support rod to move upward, and the corresponding high-density net is located above the liquid surface, and the cleaning water tank is provided with a cleaning assembly for removing mud on the high-density net.

[0016] By adopting the above technical solution, when in use, the operator starts the second electromagnet, and the second electromagnet and the second magnet generate a repulsive force, causing the support rod to move upward, while moving, driving the high-density net to move upward until the high-density net moves out of the water surface, filtering the sewage in the cleaning water tank, so that the internal mud and other impurities are moved out of the water surface with the high-density net, and then the mud and impurities on the high-density net are removed by the cleaning component, thereby filtering the water in the cleaning water tank.

[0017] Optionally, a non-woven fabric layer is provided on the high-density web.

[0018] By adopting the above technical solution and providing a non-woven fabric layer, the effect of removing impurities in the water in the cleaning water tank is further improved.

[0019] Optionally, the cleaning component includes a vacuum cleaner, an arc-shaped groove is opened on the inner wall of the cleaning water tank, the suction port of the vacuum cleaner is connected to the arc-shaped groove, and when the second magnet is located on the second electromagnet that is energized, the high-density net and the notch of the arc-shaped groove are located on the same horizontal plane.

[0020] By adopting the above technical solution, when in use, the operator starts the vacuum cleaner, and the vacuum cleaner sucks the mud and debris on the high-density net into the vacuum cleaner, which is convenient and quick.

[0021] Optionally, the active roller is a hollow structure, and the roller shaft of the active roller is also a hollow structure. The hollow structure of the active roller is connected to the hollow structure of the roller shaft of the active roller. The end of the dust removal pipe away from the hair dryer is connected to the roller shaft of the active roller through a hose. A plurality of first through grooves are provided on the side wall of the active roller. A blocking tube for blocking the first through grooves is slidably connected in the first through grooves. The blocking tube is made of iron. The top ends of the plurality of blocking tubes are commonly connected to a first limiting extension plate. The first limiting extension plate is provided with a plurality of top ends which are arranged one-to-one corresponding to the blocking tubes. An ejection spring is sleeved on the outside of the blocking tube, and a ring groove for placing the ejection spring is opened on the side wall of the hollow structure of the active roller. In a natural state, the first limiting extension plate is close to the side wall of the hollow structure of the active roller, and the ejection spring is in a compressed state. A connecting ring is rotatably connected in the hollow structure of the active roller, a first plate is provided on the connecting ring, and a third magnet is provided on the first plate. The first plate is arranged along the radial direction of the active roller. When the third magnet is opposite to the blocking tube, the blocking tube moves toward the third magnet.

[0022] By adopting the above technical solution, when in use, gas rushes into the hollow structure of the active roller, so that the first limit extension plate is squeezed, and then the ejector spring is squeezed into the corresponding annular groove. Since the connecting ring is rotatably connected to the active roller, it will not rotate with the active roller and is always in a vertical state. When the active roller drives the first limit extension plate to move to directly below the third magnet, the adsorption force of the third magnet on the blocking tube causes the blocking tube to move upward, and cooperates with the force of the support spring to restore the deformation, so that the first limit extension plate moves in the direction close to the third magnet, and the gas in the active roller is blown out from the gap of the ejector spring that restores the deformation, and blows vertically downward, which can blow the dust floating between the active roller and the driven roller into the cleaning water tank, further reducing the possibility of dust.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. This application sets a coding box, a coder, and a UV curing lamp, starts the UV curing lamp, and before the packaging bag enters the printing production line body, it first enters the coding box. When the packaging bag moves under the coder, the coder is started to code the packaging bag, and then the UV curing lamp is used to cure it. After the coding is completed, it enters the printing production line body for printing, thereby reducing the possibility that the producer will take the printed packaging bag off the winding roller and then code it through the coder, saving production steps and improving work efficiency;

[0025] 2. The present application sets a dust removal pipe, multiple dust blowing pipes and an adsorption component, starts a hair dryer, and the hair dryer blows gas from the air outlet into the dust removal pipe, and blows the gas into the dust blowing pipe through the dust removal pipe, so as to blow away the dust and debris accumulated on the packaging bag to reduce the impact on the coding. Since the packaging bag has a certain width, multiple dust blowing pipes are set, and the lengths of the multiple dust blowing pipes are gradually increased, so that the dust attached to the packaging bag can be blown multiple times, thereby reducing the air volume of the hair dryer to reduce the possibility of generating dust in the coding box, and then the dust floating in the coding box is adsorbed by the adsorption component, which further collects the dust.

[0036] Reference Figure 1 , Figure 2 and Figure 3 , the raw material packaging bags that have not been coded are placed in the workshop, which are prone to dust. The dust affects the pattern formed by the coding and also makes the brush smearing uneven. In order to solve the above problems, a dust removal pipe 8 is connected to the coding box 2. The dust removal pipe 8 is arranged along the conveying direction of the packaging bag. One end of the dust removal pipe 8 is connected to a blower 9. The dust removal pipe 8 is connected to a plurality of dust blowing pipes 10. The plurality of dust blowing pipes 10 are arranged along the length direction of the dust removal pipe 8.

[0037] Reference Figure 3 , Figure 4 and Figure 5 The adsorption component includes dust-absorbing cotton 11, and a first motor 12 is provided on the coding box 2. The output shaft of the first motor 12 is rotatably arranged on the side wall of the coding box 2. The inner side wall of the coding box 2 is rotatably connected with a driving roller 13 and a driven roller 14. The roller shaft of the driving roller 13 is connected to the output shaft of the first motor 12. An elastic waterproof belt 15 is wound around the driving roller 13 and the driven roller 14. The dust-absorbing cotton 11 is fixedly laid on the elastic waterproof belt 15. The elastic waterproof belt 15 is provided with a plurality of first through holes (not shown in the figure).

[0038] Reference Figure 3 , Figure 4 and Figure 5 , the dust-absorbing cotton 11 is arranged opposite to the dust-removing pipe 8. A cleaning water tank 16 is placed in the coding box 2, and the driven roller 14 is located in the cleaning water tank 16. The conveying direction of the packaging bag and the conveying direction of the elastic waterproof belt 15 are arranged perpendicular to each other. A first gear 17 is fixedly sleeved on the roller shaft of the driven roller 14, and a second shaft 18 is rotatably connected to the cleaning water tank 16. A second gear 19 is fixedly sleeved on one end of the second shaft 18. The first gear 17 and the second gear 19 are both located outside the cleaning water tank 16.

When the first magnet 30 is energized, a mutual repulsive force is generated between the first magnet 30 and the first electromagnet 45, so that the spring rod 26 moves quickly in the direction of the elastic waterproof belt 15.

[0040] Reference Figure 5 , Figure 6 and Figure 7 , a high-density net 31 is fixedly connected to the support rod 24, a non-woven fabric layer 32 is fixedly connected to the high-density net 31, and a plurality of high-density nets 31 enclose a whole circle, and the high-density net 31 slides with the inner wall of the cleaning water tank 16. A sliding hole for the support rod 24 to pass through is provided on the stirring rod 23, and the sliding hole is a through hole. A second magnet 33 is arranged at the bottom end of the support rod 24. When the second electromagnet 25 is opposite to the second magnet 33 and the second electromagnet 25 is energized, the repulsive force between the second electromagnet 25 and the second magnet 33 causes the support rod 24 to move upward, and the corresponding high-density net 31 is located above the liquid level, and at this time, the first magnet 30 and the first electromagnet 45 are located on the same horizontal plane. Since the second electromagnet 25 is arranged in an arc shape, there is enough time for the repulsive force generated between the first electromagnet 45 and the first magnet 30 to push the elastic rod 26 to hit the elastic waterproof belt 15.

[0041] Reference Figure 5 , Figure 6 and Figure 7 The cleaning water tank 16 is provided with a cleaning component for cleaning the mud on the non-woven fabric layer 32. The cleaning component includes a vacuum cleaner 34. An arc groove 35 is provided on the inner wall of the cleaning water tank 16. The suction port of the vacuum cleaner 34 is connected to the arc groove 35. When the second magnet 33 is located on the energized second electromagnet 25, the high-density net 31 and the notch of the arc groove 35 are located at the same horizontal plane.

[0042] Reference Figure 5 , Figure 6 and Figure 7 The active roller 13 is a hollow structure, and the roller shaft of the active roller 13 is also a hollow structure. The hollow structure of the active roller 13 is connected to the hollow structure of the roller shaft of the active roller 13, and the end of the dust removal pipe 8 away from the blower 9 is connected to the roller shaft of the active roller 13 through a hose. A plurality of first through grooves 36 connected to the hollow structure of the active roller 13 are provided on the side wall of the active roller 13, and a blocking pipe 37 for blocking the first through groove 36 is slidably connected in the first through groove 36. A plurality of air holes 38 are provided on the side wall of the blocking pipe 37, and the material of the blocking pipe 37 is iron. The top ends of the plurality of blocking pipes 37 are commonly connected to a first limit extension plate 39, and the material of the first limit extension plate 39 is iron. The cross section of the first limit extension plate 39 is arranged in an arc shape, and the first limit extension plate 39 is arranged along the length direction of the active roller 13.

[0043] Reference Figure 5 , Figure 6 and Figure 7A plurality of ejector springs 40 corresponding to the blocking tubes 37 are fixedly connected to the first limit extension plate 39, and the ejector springs 40 are sleeved outside the blocking tubes 37. An annular groove 41 for accommodating the ejector springs 40 is provided on the side wall of the hollow structure of the active roller 13. In a natural state, the first limit extension plate 39 is in close contact with the side wall of the hollow structure of the active roller 13, and the ejector springs 40 are in a compressed state and are located in the annular groove 41. When compressed, the ejector springs 40 block the air holes 38 in the annular groove 41 on the side wall of the blocking tube 37, thereby reducing the possibility that the internal gas of the active roller 13 rushes toward the elastic waterproof belt 15 after the opening of the first through groove 36 is turned away from the vertical downward state, causing the elastic waterproof belt 15 to deviate.

[0044] Reference Figure 5 , Figure 6 and Figure 7 A connecting ring 42 is rotatably connected in the hollow structure of the active roller 13, and the connecting ring 42 is arranged along the length direction of the active roller 13. A first plate 43 is connected to the connecting ring 42, and a third magnet 44 is arranged on the first plate 43. The first plate 43 is arranged along the radial direction of the active roller 13. When the third magnet 44 is facing the blocking tube 37, the blocking tube 37 moves toward the direction of the third magnet 44.

[0045] The implementation principle of a packaging bag printing production line in the embodiment of the present application is as follows: when in use, the operator starts the UV curing lamp 7, and before the packaging bag enters the printing production line body 1, it first enters the coding box 2 from the feed port 3, and the operator starts the blower 9, and the blower 9 blows the gas from the air outlet to the dust removal pipe 8, and then blows it into the dust blowing pipe 10 through the dust removal pipe 8, which can blow away the dust and debris accumulated on the packaging bag to reduce the impact on the coding. Since the packaging belt has a certain width, multiple dust blowing pipes 10 are set, and the lengths of the multiple dust blowing pipes 10 gradually increase, which can achieve multiple blowing of the dust attached to the packaging bag, so as to reduce the air volume of the blower 9 to reduce the possibility of generating dust in the coding box 2;

[0046] At the same time, the operator starts the first motor 12, and the first motor 12 drives the active roller 13 to rotate. Under the cooperation of the elastic waterproof belt 15, the active roller 13 and the driven roller 14 rotate together. The elastic waterproof belt 15 drives the dust-absorbing cotton 11 to enter the cleaning water tank 16. The dust-absorbing cotton 11 is wetted by water. When the wet dust-absorbing cotton 11 rotates to the side opposite to the dust-blowing pipe 10, the dust blown off the packaging bag is absorbed by the dust-absorbing cotton 11, and the elastic waterproof belt 15 with dust attached enters the cleaning water tank 16. At the same time, the roller of the rotating driven roller 14 The shaft drives the first gear 17 to rotate, the first gear 17 is meshed with the second gear 19, the second gear 19 drives the second shaft 18 to rotate, and then the first bevel gear 20 is rotated, the first bevel gear 20 is meshed with the second bevel gear 21, so that the first shaft 22 is rotated, and the first shaft 22 drives the stirring rod 23 to rotate, so that the water in the cleaning water tank 16 is rotated, which has a stirring effect on the water, can reduce the possibility of dust entering the cleaning water tank 16 adhering to the tank wall, and also reduce the possibility of impurities being deposited at the bottom of the cleaning water tank 16;

[0047] The rotating stirring rod 23 drives the supporting rod 24 to rotate, and starts the second electromagnet 25. When the second magnet 33 moves to the top of the second electromagnet 25, the second electromagnet 25 and the second magnet 33 generate a repulsive force, so that the supporting rod 24 moves upward, and at the same time drives the high-density net 31 to move upward, until the high-density net 31 moves out of the water surface, and the sewage in the cleaning water tank 16 is filtered, so that the internal mud and other impurities are moved out of the water surface with the high-density net 31, and then the mud and impurities on the high-density net are removed by the cleaning component, so that the water in the cleaning water tank 16 is filtered, and the moving supporting rod 24 drives the elastic rod 26 to move upward, and finally the first magnet 30 and the first electromagnet 45 are in On the same horizontal plane, the first electromagnet 45 is energized. When the first magnet 30 rotates to a position opposite to the first electromagnet 45, a repulsive force is generated between the first electromagnet 45 and the first magnet 30. The repulsive force causes the limit plate 27 to move toward the direction of the driven roller 14 and hit the elastic waterproof belt 15. Since the elastic waterproof belt 15 to which the elastic rod 26 is facing is dust adsorbed after being soaked in water, dust forms ash balls after meeting water, which can make the dust attached to the dust-absorbing cotton 11 fall off. At the same time, the possibility of dust generation is reduced, and the ash balls attached to the dust-absorbing cotton 11 are cleared. In summary, the adverse effects of dust attached to the packaging belt on coding and printing in subsequent steps are reduced.

[0048] When the packaging bag after the dust is cleaned continues to move under the inkjet printer 6, the inkjet printer 6 is started to print the code on the packaging bag, and then the UV curing lamp 7 is used to cure it. After the coding is completed, it enters the printing production line body 1 for printing, thereby reducing the possibility of the producer taking the printed packaging bag off the winding roller and then coding it through the coder, saving production steps and improving work efficiency.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
