Description

Technical Field

[0001] The present invention is used in the field of inkjet printing, and particularly relates to a spiral inkjet printer. Background Art

[0002] An inkjet printer is a high-tech digital printing device of the "non-contact with the object" inkjet printing type. It can print on various surfaces without any material restrictions, such as wooden boards, glass, metal plates, floor tiles, plexiglass, leather, fabrics, self-adhesive labels, stones, etc. in color photo quality. The pattern can be printed in one pass without plate making, without plate burning and repeated color registration. The colors are bright and the effect is vivid. It has the advantages of low printing cost and high clarity, and is widely used in modern society.

[0003] Existing inkjet printers can only perform inkjet printing on regular-shaped cylindrical products and flat-shaped products, and have poor printing effects on other irregular-shaped special-shaped products. Summary of the Invention

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present invention provides a spiral inkjet printer. The technical solutions adopted are as follows.

[0005] A spiral inkjet printer includes a turntable, a loading station, an inkjet station, and an unloading station. The loading station, the inkjet station, and the unloading station are all arranged around the turntable. The turntable is provided with a product fixing device. The turntable can drive the product fixing device to rotate. The product fixing device includes a first fixing seat, a clamp, and a clamp driving device. There are multiple clamp driving devices, and each clamp driving device is installed on the first fixing seat. The power output end of each clamp driving device is installed with the clamp. The clamp driving device can drive the clamp to rotate. The inkjet station includes an ink carriage and a curing device. The ink carriage includes a first base, a first lifting mechanism, a first transverse movement mechanism, and an inkjet device. The first transverse movement mechanism is installed on the first base. The first lifting mechanism is installed at the transverse movement end of the first transverse movement mechanism. The inkjet device is connected to the lifting end of the first lifting mechanism. The inkjet device is provided with multiple nozzles. The curing device is arranged below the ink carriage. There is a spacing for the product to enter between the curing device and the inkjet device.

[0006] The spiral inkjet printer according to the embodiment of the present invention has at least the following beneficial effects: During the working process, the product is conveyed to the fixture on the turntable through the loading station. The rotation of the turntable moves the product on the fixture to the inkjet station. Then, under the cooperative action of the first lifting mechanism and the first transverse movement mechanism, the inkjet device is moved above the product, so that the product is located between the inkjet device and the curing device. The inkjet device starts to inkjet. At the same time, the fixture driving device drives the fixture to rotate, so that the fixture drives the product to rotate. The first transverse movement mechanism drives the inkjet device to move from one end of the product to the other end. Since this device performs spiral inkjet on the product under the action of the rotation of the fixture and the transverse movement of the inkjet device during the inkjet process, it is not restricted by the product structure and can also achieve good printing for products with special-shaped structures, and the printing effect is better.

[0025] Referring to Figures 1 to 17 , the present invention provides a spiral inkjet printer, including a turntable 1, a feeding station 2, an inkjet station, and a discharging station 3. The feeding station 2, the inkjet station, and the discharging station 3 are arranged around the turntable 1. A product fixing device 4 is provided on the turntable 1. The turntable 1 can drive the product fixing device 4 to rotate. The product fixing device 4 includes a first fixing seat 5, a fixture 6, and a fixture driving device. There are multiple fixture driving devices, and each fixture driving device is installed on the first fixing seat 5. The power output end of each fixture driving device is installed with a fixture 6. The fixture driving device can drive the fixture 6 to rotate self. The inkjet station includes an ink carriage 7 and a curing device 8. The ink carriage 7 includes a first base 9, a first lifting mechanism 10, a first transverse movement mechanism 11, and an inkjet device 12. The first transverse movement mechanism 11 is installed on the first base 9. The first lifting mechanism 10 is installed on the transverse movement movable end of the first transverse movement mechanism 11. The inkjet device 12 is connected to the lifting movable end of the first lifting mechanism 10. Multiple nozzles are provided on the inkjet device 12. The curing device 8 is arranged below the ink carriage 7. There is a spacing for the product 001 to enter between the curing device 8 and the inkjet device 12.

[0026] During the working process, product 001 is conveyed to fixture 6 on turntable 1 through loading station 2. The turntable 1 rotates to move product 001 on fixture 6 to the inkjet station. Then, under the coordinated action of the first lifting mechanism 10 and the first transverse movement mechanism 11, the inkjet device 12 is moved above product 001, making product 001 located between the inkjet device 12 and the curing device 8. The inkjet device 12 starts to inkjet. At the same time, the fixture driving device drives fixture 6 to rotate self. The first transverse movement mechanism 11 drives the inkjet device 12 to move from one end of product 001 to the other end. Since this device realizes inkjet printing under the action of the self-rotation of fixture 6 and the transverse movement of the inkjet device 12 during the inkjet process, the inkjet device 12 will perform spiral inkjet on product 001, and it is not restricted by the structural shape of product 001. For products 001 with special-shaped structures, good printing can also be achieved, and the printing effect is better.

[0027] In some embodiments, a pneumatic device is provided on turntable 1. Each fixture 6 communicates with the pneumatic device, and air holes are provided on fixture 6.

[0028] Specifically, the pneumatic device is used to inflate or extract air inside fixture 6. When loading station 2 slews product 001 onto fixture 6, the pneumatic device extracts air, and the air inside product 001 is extracted through the air holes on fixture 6, making product 001 adsorbed and fixed to fixture 6, preventing the problem of product 001 moving during the subsequent rotation of turntable 1 or the inkjet process.

[0029] To ensure that the inkjet device 12 can accurately move above product 001, in some embodiments, a first lifting cylinder 13 and a second lifting cylinder are respectively arranged on both sides of the inkjet device 12. A first sensing device 14 is arranged at the lifting movable end of the first lifting cylinder 13, and a second sensing device is arranged at the lifting movable end of the second lifting cylinder. The first sensing device 14 and the second sensing device perform mutual opposed sensing, and the opposed light between the first sensing device 14 and the second sensing device is flush with the spraying end of the nozzle.

[0030] During the working process, first, the inkjet device 12 needs to be moved above the product 001 so that the distance between the nozzle of the inkjet device 12 and the product 001 reaches the spraying distance a of the nozzle. The specific working process is as follows: The turntable 1 rotates to drive the product 001 to rotate between the inkjet device 12 and the curing device 8. The first lifting cylinder 13 and the second lifting cylinder jointly drive the first sensing device 14 and the second sensing device to descend together below the inkjet device 12. Then, the first lifting mechanism 10 drives the entire inkjet device 12 to descend. At this time, the inkjet device 12 will drive the first sensing device 14 and the second sensing device to descend together. When the descending first sensing device 14 and the second sensing device are blocked by the product 001 on the fixture 6, the first lifting mechanism 10 stops driving and records the overall descending distance X of the inkjet device 12 at this time. Then, the first lifting mechanism 10 drives the entire inkjet device 12 to rise by a distance of X - a, so that the nozzle moves to a position a above the product 001. Then, the first lifting cylinder 13 and the second lifting cylinder drive the first sensing device 14 and the second sensing device to rise to the initial position. Finally, the fixture 6 on the turntable 1 drives the product 001 to rotate, and at the same time, the first lateral movement mechanism 11 drives the inkjet device 12 to move from one end of the product 001 to the other end, so that the nozzle sprays the ink spirally on the surface of the product 001 to achieve spiral printing. This pair of first sensing device 14 and second sensing device that are opposite to each other can make the nozzle on the inkjet device 12 accurately move to a predetermined distance above the product 001. Therefore, no matter what size the product 001 is, the equipment of the present application can be applicable, and the debugging process is more time-saving and labor-saving.

[0031] In some embodiments, both the first sensing device 14 and the second sensing device are photoelectric sensing switches.

[0032] The first lateral movement mechanism 11 includes a first lateral movement driving device and a first lateral movement seat 15. The first lateral movement driving device is installed on the first base 9, and the first lateral movement seat 15 is slidably installed on the first base 9 and connected to the power output end of the first lateral movement driving device.

[0033] The first lateral movement driving device includes a servo motor and a ball screw. The ball screw is connected to the power output end of the servo motor. The ball screw is connected to the first lateral movement seat 15. The servo motor drives the ball screw to drive the first lateral movement seat 15 to slide laterally through the ball screw.

[0034] The first lifting mechanism 10 includes a first driving cylinder and a first lifting seat. A first lifting slider is provided on the first lateral movement seat 15, and a first lifting guide rail is provided on the first lifting seat. The first lifting slider is slidably installed on the first lifting guide rail. The first driving cylinder is installed on the first lateral movement seat 15, and the first lifting seat is connected to the power output end of the first driving cylinder.

[0035] Specifically, two parallel first lifting guide rails are vertically provided on the side of the first lifting seat. Four first lifting sliders are provided on the first transverse moving seat 15. Two first lifting sliders are slidably assembled on each first lifting guide rail, so as to realize the sliding connection between the first lifting mechanism 10 and the first transverse moving seat 15.

[0036] The curing device 8 includes a first base 16, a first light module and a first light shielding plate 17. The first light module is installed on the first base 16. The first light module includes a first bracket 18 and a plurality of light emitting devices 19. Each light emitting device 19 is installed on the first bracket 18. Each light emitting device 19 is arranged at intervals along the length direction of the first bracket 18. Each light emitting device 19 is aligned with each product 001 one by one. First light shielding plates 17 are provided on both sides of each light emitting device 19, and the first light shielding plates 17 can move up and down.

[0037] After the inkjetting of the product 001 is completed, the first light shielding plates 17 on both sides of each light emitting device 19 rise, so as to separately limit each light emitting device 19 and the product 001 on the corresponding fixture 6 in a space. Then the light emitting device 19 emits light to cure the product 001. During the curing process, since the adjacent two products 001 are separated by the first light shielding plate 17, the adjacent products 001 will not be interfered by light either. It is ensured that the light irradiated by each light emitting device 19 only irradiates the corresponding product 001 and will not irradiate other products 001. Therefore, the light received by each product 001 is equal, so that the curing effect of the product 001 is more uniform.

[0038] In some embodiments, the light emitting device 19 includes an LED lamp.

[0039] In some embodiments, an anti-collision detection device is provided on one side of the inkjet device 12. The anti-collision detection device includes a detection plate 20, an elastic member 21 and an induction member 22. The detection plate 20 is installed on the side of the inkjet device 12 through the elastic member 21. The lower edge of the detection plate 20 is lower than the lowest point of the inkjet device 12. The induction member 22 is installed on the inkjet device 12, and the induction member 22 is used to sense the detection plate 20.

[0040] Specifically, the elastic component 21 is a torsion spring. The detection plate 20 is vertically installed on the side of the inkjet device 12 through the torsion spring. The sensing component 22 is a photoelectric sensing device. In the normal state, the detection plate 20 blocks the opposed light of the sensing device. During the working process, when the turntable 1 drives the product 001 into the spacing between the inkjet device 12 and the curing device 8, if the product 001 touches the detection plate 20, the detection plate 20 will rotate, causing the opposed light of the sensing component 22 to lose the block. At this time, the system senses that the detection plate 20 has changed, indicating that the product 001 will touch the bottom of the inkjet device 12 when it turns in. Therefore, the turntable 1 will stop rotating, thus preventing the product 001 from colliding with the inkjet device 12.

[0041] In some embodiments, the inkjet station of the printing press further includes a moisturizing device 23. The moisturizing device 23 includes a moisturizing basin 24, a moisturizing chamber 25, and a water pipe. The moisturizing basin 24 is provided with a plurality of moisturizing chambers 25. Water pipes connecting to the outside are provided at the bottoms of the respective moisturizing chambers 25. The nozzles are to be inserted into the moisturizing chambers 25.

[0042] Specifically, a plurality of moisturizing chambers 25 are arranged at intervals in the moisturizing basin 24. The number of the moisturizing chambers 25 is the same as the number of the nozzles on the inkjet device 12. The spacing between the respective moisturizing chambers 25 is the same as the spacing between the respective nozzles. When it is necessary to remove the cured ink on each nozzle, driven by the lifting and transverse movement of the first lifting mechanism 10 and the first transverse movement mechanism 11, the respective nozzles on the inkjet device 12 will be inserted into the moisturizing chambers 25. Then, the inkjet device 12 pressurizes the ink, so that the pressurized ink sprays the blockage on the nozzle into the moisturizing chamber 25, and then flows out through the water pipe, so that the nozzles can be in a moisturized state.

[0043] In some embodiments, the mouth of the moisturizing chamber 25 is covered by rubber 26. After the nozzle of the inkjet device 12 is inserted into the moisturizing chamber 25, the outer wall of the nozzle will press against the rubber 26, thereby improving the sealing performance between the nozzle and the moisturizing chamber 25.

[0044] In some embodiments, a scraping device is provided on the moisturizing device 23. The scraping device includes a power motor 27, a transmission device 28, a rotating shaft 29, and a plurality of scraping plates 30. The power motor 27 is installed on one side of the moisturizing basin 24. The rotating shaft 29 is rotatably installed on the moisturizing basin 24. The power motor 27 is connected to the power output end of the rotating shaft 29 through the transmission device 28. The power motor 27 is used to drive the rotating shaft 29 to rotate axially along the rotating shaft 29. The respective scraping plates 30 are fixed on the rotating shaft 29. One scraping plate 30 is provided on one side of each moisturizing chamber 25.

[0045] Specifically, the rotating shaft 29 is installed on one side of the moisture preservation basin 24 close to the inkjet device 12. The rotating shaft 29 extends along the length direction of the moisture preservation basin 24. An inclined ink scraping plate 30 is installed on the rotating shaft 29. After the inkjet device 12 flushes the nozzle, the first lifting mechanism 10 drives the inkjet device 12 to be pulled out of the moisture preservation bin 25, and then the power motor 27 drives the rotating shaft 29 to rotate. The rotation of the rotating shaft 29 drives the ink scraping plate 30 to scrape the residual ink liquid on the nozzle, preventing the ink from dripping randomly and causing pollution.

[0046] In some embodiments, the inkjet station of the printing press further includes a storage box. The storage box includes a second base 301, a first flip cover 31 and a second flip cover 32. The first flip cover 31 and the second flip cover 32 are both rotatably installed on the top of the second base 301. The first flip cover 31 and the second flip cover 32 are arranged oppositely. The second base 301, the first flip cover 31 and the second flip cover 32 jointly define a storage cavity, and the moisture preservation device 23 is stored in the storage cavity.

[0047] When the nozzle of the inkjet device 12 needs to be inserted into the moisture preservation bin 25 on the moisture preservation basin 24, the first flip cover 31 and the second flip cover 32 are flipped open, so that the moisture preservation device 23 is exposed. After the nozzle of the inkjet device 12 is rinsed in the moisture preservation basin 24, the first flip cover 31 and the second flip cover 32 are flipped to cover the moisture preservation device 23, thus playing a role in protecting the moisture preservation device 23.

[0048] In some embodiments, a second lifting mechanism is provided in the storage cavity, and the lifting movable end of the second lifting mechanism is connected to the moisture preservation basin 24.

[0049] Specifically, after the inkjet device 12 moves to directly above the moisture preservation device 23, the second lifting mechanism in the storage cavity can rise to lift the entire moisture preservation device 23, facilitating the insertion of the nozzle into the moisture preservation bin 25.

[0050] The second lifting mechanism can adopt structures such as a driving cylinder or a driving oil cylinder, or can also adopt a structure of a servo motor driving a ball screw.

[0051] In some embodiments, the storage box further includes a flip cover driving mechanism. The flip cover driving mechanism includes a third lifting mechanism 33, a first lifting rod 34, a second lifting rod 35, a connecting plate 36, and a first rotating rod 37 and a second rotating rod 38. The third lifting mechanism 33 is installed on the second base 301. The first lifting rod 34 and the second lifting rod 35 are connected to the power output end of the third lifting mechanism 33. The connecting plate 36 connects the first lifting rod 34 and the second lifting rod 35. One end of the first rotating rod 37 is rotatably connected to the first flip cover 31, and the other end is rotatably connected to the connecting plate 36. One end of the second rotating rod 38 is rotatably connected to the second flip cover 32, and the other end is rotatably connected to the connecting plate 36.

[0052] In some other embodiments, flap driving mechanisms are provided on both sides of the first flap 31 and the second flap 32. During the working process, the two flap driving mechanisms drive the first flap 31 and the second flap 32 to open or retract simultaneously.

[0053] Specifically, the third lifting mechanism 33 is a cylinder installed below the second base 301. The power output end of the third lifting mechanism 33 faces downward. The first lifting rod 34 and the second lifting rod 35 are vertically arranged in the second base 301 and can move up and down. Support rods 39 are provided at the four corners of the second base 301. The two ends of the first flap 31 are rotatably installed between the two support rods 39. The two ends of the second flap 32 are rotatably installed between the two support rods 39. The tops of the two first lifting rods 34 are connected by a connecting plate 36. The bottoms of the two second lifting rods 35 are connected by a connecting block 40. The power output end of the third lifting mechanism 33 is rotatably connected to the middle of the connecting block 40. One end of the first rotating rod 37 is rotatably connected to the connecting plate 36, and the other end is rotatably connected to the side of the first flap 31. One end of the second rotating rod 38 is rotatably connected to the connecting plate 36, and the other end is rotatably connected to the side of the second flap 32.

[0054] During the working process, the third lifting mechanism 33 drives the first lifting rod 34 and the second lifting rod 35 to lift and lower synchronously, so that the first lifting rod 34 and the second lifting rod 35 drive the connecting plate 36 to lift and lower. When the connecting plate 36 descends, it will drive the first rotating rod 37 and the second rotating rod 38 to rotate towards each other, thereby realizing the closing of the first flap 31 and the second flap 32. When the connecting plate 36 ascends, it will drive the first rotating rod 37 and the second rotating rod 38 to rotate away from each other, thereby realizing the opening of the first flap 31 and the second flap 32.

[0055] In some embodiments, there are multiple inkjet stations. Each inkjet station is arranged around the turntable 1 in sequence, and the inks ejected by each inkjet station are different.

[0056] Specifically, there are four inkjet stations, namely the first inkjet station 41, the second inkjet station 42, the third inkjet station 43, and the fourth inkjet station 44. The four inkjet stations are connected and arranged around the turntable 1 in sequence. Among them, the first inkjet station 41 is used to eject white ink onto the product 001, the second inkjet station 42 is used to eject the first color ink onto the product 001, the third inkjet station 43 is used to eject the second color ink onto the product 001, and the fourth inkjet station 44 is used to eject light ink onto the product 001.

[0057] In some embodiments, the present application further includes an electrostatic dust removal station 45, which is arranged between the loading station 2 and the inkjet station. The electrostatic dust removal station 45 includes a first support 46, an electrostatic dust removal rod 47, and a dust suction hood 48. A plurality of electrostatic dust removal rods 47 are provided on the first support 46. Spray nozzles are provided on the electrostatic dust removal rods 47 for spraying charged ions and gas. The dust suction hood 48 is arranged above each electrostatic dust removal rod 47, and a dust suction fan 49 is provided on the dust suction hood 48.

[0058] Specifically, the electrostatic dust removal station 45 is arranged between the loading station 2 and the first inkjet station 41. Before the turntable 1 drives the product 001 into the inkjet station, the electrostatic dust on the product 001 and the dust are removed through the electrostatic dust removal station 45.

[0059] Specifically, a plurality of electrostatic dust removal rods 47 are arranged side by side and spaced apart on the first support 46. Each electrostatic dust removal rod 47 corresponds to a product 001. After the turntable 1 drives the product 001 to move to the electrostatic dust removal station 45, the product 001 will move between the electrostatic dust removal rod 47 and the dust suction hood 48 and be directly above the electrostatic dust removal rod 47. At this time, the electrostatic dust removal rod 47 will spray negatively charged ions and gas from the spray nozzle. After the negatively charged ions are sprayed onto the product 001, they will neutralize the positively charged dust particles on the surface of the product 001, so that the dust particles on the product 001 are separated from the surface of the product 001, and then are blown to the dust suction hood 48 by the gas sprayed from the spray nozzle, and the dust is sucked away by the dust suction fan 49, finally realizing the functions of removing static electricity and dust.

[0060] After the product 001 undergoes electrostatic dust removal, it is necessary to rotate and position the product 001 so that the marking position on the product 001 is directly opposite to the inkjet device 12, so that the inkjet device 12 can spray more precisely during the inkjet process. Therefore, in some embodiments, the present application further includes a positioning station 50, which is arranged between the inkjet station and the electrostatic dust removal station 45. The positioning station 50 includes a second support 51, a transverse sliding seat 52, a rotating device, and a clamping device. The transverse sliding seat 52 is slidably mounted on the second support 51. A plurality of clamping devices and rotating devices are provided. Each clamping device corresponds to each fixture 6. Each clamping device is mounted on the transverse sliding seat 52 through a rotating device, and the rotating device can drive the clamping device to rotate self.

[0061] Specifically, the clamping device includes a clamping jaw 53 and a clamping jaw driving cylinder 54. The clamping jaw driving cylinder 54 can drive the clamping jaw 53 to separate or approach, so as to realize the action of clamping the product 001. The rotating device includes a first transmission wheel 55, a second transmission wheel 56, a transmission belt and a driving cylinder 57. The driving cylinder 57 is installed on the transverse sliding seat 52. The first transmission wheel 55 is connected to the power output end of the driving cylinder 57. The second transmission wheel 56 is installed on the clamping jaw driving cylinder 57. The transmission belt connects the first transmission wheel 55 and the second transmission wheel 56. A first fixing block 58 is fixed above the driving cylinder 57. The clamping jaw driving cylinder 54 is rotatably installed on the first fixing block 58. During the working process, after the clamping jaw 53 of the clamping device clamps the product 001, the driving cylinder 57 drives the first transmission wheel 55 to rotate. The first transmission wheel 55 drives the second transmission wheel 56 to rotate through the transmission belt. The second transmission wheel 56 drives the entire clamping device to rotate, so that the clamping jaw 53 clamps the product 001 and rotates, making the marking position on the product 001 rotate to the side facing the inkjet device 12, which is convenient for inkjetting.

[0062] In some embodiments, a total curing station 59 is provided between the inkjet station and the blanking station 3. The total curing station 59 includes a second base 60, a second lighting module 61 and a light-shielding cover 62. The second lighting module 61 is installed on the second base 60. The second lighting module 61 includes a second bracket 63 and a plurality of light-emitting devices 64. Each light-emitting device 64 is installed on the second bracket 63. Each light-emitting device 64 is arranged at intervals along the length direction of the second bracket 63. Each light-emitting device 64 is aligned with each product 001 one by one. The light-shielding cover 62 is arranged above the second lighting module 61. Second light-shielding plates 65 are provided on both sides of each light-emitting device 64. The second light-shielding plates 65 can move up and down, and the second light-shielding plates 65 can rise to connect with the light-shielding cover 62.

[0063] When curing the product 001, the product 001 on the printing machine fixture 6 rotates to between the light-shielding cover 62 and the second lighting module 61. Then the second light-shielding plates 65 on both sides of each light-emitting device 64 rise until the top of the second light-shielding plates 65 is connected to the light-shielding cover 62, so as to separately limit each light-emitting device 64 and the product 001 on the corresponding fixture 6 in a space. Then the light-emitting device 64 emits light to cure the product 001. During the curing process, since adjacent products 001 are separated by the second light-shielding plates 65, there is no light interference between adjacent products 001. It is ensured that the light irradiated by each light-emitting device 64 only irradiates the corresponding product 001 and does not irradiate other products 001. Therefore, the light received by each product 001 is equal, making the curing effect of the product 001 more uniform.

[0064] In some embodiments, the second bracket 63 includes a front side plate 66, a rear side plate 67, a left side plate, and a right side plate. The front side plate 66 and the rear side plate 67 are arranged opposite to each other at intervals. The left side plate and the right side plate are respectively fixed at both ends of the front side plate 66 and the rear side plate 67. Both ends of the light-emitting device 64 are connected to the front side plate 66 and the rear side plate 67.
