Description

Technical Field

[0001] The invention belongs to the technical field of printing equipment, and in particular relates to a marking printer. Background Art

[0002] A tag printer is a device specially used to print labels, barcodes, QR codes, production dates, serial numbers and other information. It can be used for product identification, inventory management, tracking and information recording, etc. During the working process of the tag printer, it is necessary to first take out the label or printing medium from the supply tray or reel, and then send the label or paper to the printing area. The printing system prints according to the set content (in this process, different printing technologies will use different methods to transfer ink or heat to the label), and then cut the printed labels. Finally, the printed labels are sent to the output end or label stacking area to ensure the printing of high-quality labels and tags.

[0003] Traditional marking printers need to coat the marking head with ink before use, so there are usually the following technical problems: 1. When the ink is cast onto the marking head, due to its low fluidity, the ink is easy to clump or thicken at the ink coating port, resulting in blockage and uneven ink distribution. This causes the marking head in the marking printer to be prone to uneven coating during coating. At the same time, long-term printing operations will cause the temperature of the ink coating port to rise, which may cause the ink coating port to overheat and be damaged, reducing the coating quality and printing quality; 2. Since the pigment particles contained in the ink are easily settled due to gravity, the ink is prone to precipitation or stratification in the ink cartridge, resulting in uneven color concentration, which in turn causes the marking head after coating to have inconsistent colors or fade when marking, greatly reducing the marking quality of the marking printer. Summary of the invention

The vortex component 3 includes a mounting plate 31 fixedly connected to the inside of the body 1, a vortex tube 32 is fixedly connected to the side wall of the mounting plate 31, a heating box 33 is fixedly connected to the side wall of the mounting plate 31, a heating tube 34 is connected to the hot air output end of the vortex tube 32 and the heating box 33, an ink cartridge 35 connected to the ink coating port 2 is fixedly connected to the side wall of the mounting plate 31, an ink delivery channel 36 and an ink delivery channel 37 are respectively connected to the two sides of the ink cartridge 35 and the heating box 33, a first one-way valve is provided in the ink delivery channel 36 and the ink delivery channel 37, an annular cooling channel 38 is fixedly connected to the peripheral side of the ink coating port 2, a cooling tube 39 connected to the annular cooling channel 38 is connected to the cold air output end of the vortex tube 32, and an air compressor is connected to the upper end of the vortex tube 32.

[0025] In view of the problem that in the prior art, due to low fluidity, the ink is easy to clump or thicken at the ink coating port 2, resulting in blockage, uneven ink distribution and other problems, which causes the marking head 12 in the marking printer to be prone to uneven coating during coating. At the same time, long-term printing operations will cause the temperature of the ink coating port 2 to rise, resulting in overheating and damage of the ink coating port 2, thereby reducing the coating quality and printing quality. The present invention provides a vortex component 3, and before printing, the hot air generated by the vortex tube 32 can be transported to the heating box through the heating tube 34 33, the ink is heated to maintain its fluidity, prevent the ink from agglomerating or thickening at the ink coating port 2, and ensure that the ink can be evenly coated on the marking head 12. At the same time, the cold air generated by the vortex tube 32 can be transported to the annular cooling channel 38 on the side of the ink coating port 2 through the cooling tube 39 to cool the ink coating port 2, avoid overheating and damage to the ink coating port 2, and improve the coating quality and printing quality. Only one vortex tube 32 is required to simultaneously achieve heating of the ink and cooling of the ink coating port 2.

[0026] The vortex component 3 here can be set not only at the ink coating port 2 of the marking printer, but also at the nozzle of the inkjet printer. There is no limitation here and the application range is relatively wide.

[0027] It also includes a circulation component 4 for circulating the ink to prevent the ink from settling or stratifying. The circulation component 4 includes a suction cylinder 41 fixedly connected to the side wall of the mounting plate 31. The ink supply channel 36 is divided into two sections, an ink suction tube 42 and an ink discharge tube 43 connected to the two side walls of the suction cylinder 41. A second one-way valve is provided in the ink suction tube 42 and the ink discharge tube 43. The interior of the suction cylinder 41 is sealingly and slidably connected to a piston plate 44. A motor 45 is fixedly connected to the side wall of the mounting plate 31. A driving rod 46 is fixedly connected to the output end of the motor 45. A turntable 47 is fixedly connected to the end of the driving rod 46 away from the motor 45. A fixed shaft 48 is fixedly connected to the eccentric part of the turntable 47 away from the driving rod 46. A connecting rod 49 is rotatably sleeved on the fixed shaft 48. The bottom end of the connecting rod 49 is hinged to the upper wall of the piston plate 44.

[0028] Among them, the setting of the first one-way valve and the setting of the second one-way valve ensure that when the piston plate 44 reciprocates vertically, the ink can only flow in the clockwise direction in the ink cartridge 35, the ink extraction tube 42, the suction cylinder 41, the ink discharge tube 43, the heating box 33 and the ink delivery channel 37 in sequence, thereby avoiding the backflow of ink and ensuring the circulation of ink.

[0029] In view of the problem that the pigment particles contained in the ink in the prior art are easily precipitated due to gravity, resulting in the phenomenon that the ink is easily precipitated or layered in the ink cartridge 35, resulting in uneven color concentration, and then causing the marking head 12 after coating to have inconsistent colors or fade when marking, which greatly reduces the marking quality of the marking printer, the present invention sets a circulation component 4. Before printing, the motor 45 can drive the driving rod 46 to rotate, thereby driving the rotating disk 47 to rotate, and the fixed shaft 48 on the rotating disk 47 drives one end of the connecting rod 49 to perform a circular motion, so that the bottom end of the connecting rod 49 The piston plate 44 is driven to perform reciprocating vertical displacement in the suction cylinder 41, forming a structure similar to a suction pump, and the ink is reciprocatingly drawn into the suction cylinder 41 through the ink extraction tube 42, and the ink in the suction cylinder 41 is reciprocatingly pumped into the heating box 33 through the ink discharge tube 43, so that the ink can circulate in the ink cartridge 35, the ink extraction tube 42, the suction cylinder 41, the ink discharge tube 43, the heating box 33 and the ink delivery channel 37. The ink is circulated while being heated, so as to keep the ink evenly mixed in the ink cartridge 35, prevent the ink from settling or stratifying, and improve the marking quality of the marking head after coating.

[0030] It also includes a cleaning component 5 for periodically cleaning the ink coating port 2. The cleaning component 5 includes a rotating rod 51 rotatably connected to the side wall of the mounting plate 31, a gear 52 is fixedly connected to the rotating rod 51, a transmission rod 53 is rotatably connected to the side wall of the mounting plate 31, an arc-shaped tooth groove 54 periodically meshing with the gear 52 is fixedly connected to the transmission rod 53, an L-shaped rod 55 is fixedly connected to the rotating rod 51, a cleaning brush plate 56 is fixedly connected to the L-shaped rod 55, a stop block 57 is fixedly connected to the side wall of the mounting plate 31, and a spring 58 is provided between the L-shaped rod 55 and the stop block 57.

[0031] Among them, a transmission component 6 for saving driving source is provided between the cleaning component 5 and the circulation component 4. The transmission component 6 includes a synchronous wheel 61 fixedly connected to the driving rod 46 and the transmission rod 53, and a synchronous belt 62 is sleeved between the two synchronous wheels 61.

[0032] It is worth mentioning that the present invention sets a cleaning component 5. When the driving rod 46 rotates, the transmission rod 53 is driven to rotate through the synchronous wheel 61 and the synchronous belt 62, and the gear 52 is further driven to rotate periodically through the arc-shaped tooth groove 54, so that the cleaning brush plate 56 can be periodically rotated counterclockwise, and under the elastic force of the spring 58, it periodically rotates clockwise to return to the initial position. The reciprocating swing of the cleaning brush plate 56 has a cleaning effect on the ink coating port 2, preventing the ink from drying up or clogging at the ink coating port 2 during the coating process, thereby improving the coating effect and coating efficiency of the marking head 12. At the same time, there is no need to set an additional driving source, which saves costs and improves work efficiency.

[0033] An intersection assembly 7 for improving the cleaning effect of the ink coating port 2 is provided between the vortex assembly 3 and the cleaning assembly 5. The intersection assembly 7 includes an intersection box body 71 fixedly connected to the side wall of the mounting plate 31, and an exhaust port is opened on the side wall of the intersection box body 71. The side wall of the annular cooling channel 38 is connected to a cold air exhaust pipe 72 connected to the upper wall of the intersection box body 71, and the side wall of the heating box 33 is connected to a hot air exhaust pipe 73 connected to the lower wall of the intersection box body 71. The interior of the intersection box body 71 is fixedly connected to an inclined water filter plate 74, and the side wall of the intersection box body 71 near the cleaning brush plate 56 is connected to a drainage channel 75, and the other end of the drainage channel 75 is connected to an arc-shaped water storage cylinder 76, and the arc-shaped water storage cylinder 76 is fixed to the mounting plate 31, and the cleaning brush plate 56 is initially in the arc-shaped water storage cylinder 76.

[0034] It should be noted that the present invention sets a junction component 7, and after the hot air generated by the vortex tube 32 passes through the heating box 33 to heat the ink, it will flow back to the junction box body 71 through the hot air exhaust pipe 73; after the cold air generated by the vortex tube 32 cools the ink coating port 2, it will flow back to the junction box body 71 through the cold air exhaust pipe 72, so that the hot and cold air in the junction box body 71 converge to generate condensate beads, and the condensate beads are transported to the arc-shaped water storage cylinder 76 through the inclined water filter plate 74 and the drainage channel 75, so that the cleaning brush plate 56 can enter the arc-shaped water storage cylinder 76 for cleaning every time it rotates clockwise to reset, which not only improves the cleaning effect of the ink coating port 2, but also makes full use of the hot and cold air generated by the vortex tube 32, thereby saving water resources.

[0035] The present invention can be explained by the following operation mode: Before marking, the hot air generated by the vortex tube 32 is transported to the heating box 33 through the heating tube 34 to heat the ink to prevent the ink from agglomerating or thickening at the ink coating port 2. At the same time, the cold air generated by the vortex tube 32 is transported to the annular cooling channel 38 on the side of the ink coating port 2 through the cooling tube 39 to cool the ink coating port 2. The ink in the ink cartridge 35 is cast onto the marking head 12 through the ink coating port 2 by a suction pump to coat the marking head 12. The motor 45 drives the driving rod 46 to rotate, thereby driving the rotating disk 47 to rotate, and the fixed shaft 48 on the rotating disk 47 drives one end of the connecting rod 49 to perform circular motion, so that the bottom end of the connecting rod 49 can drive the piston plate 44 to perform reciprocating vertical displacement in the suction cylinder 41, and the ink is reciprocatingly pumped into the suction cylinder 41 through the ink extraction tube 42, and the ink in the suction cylinder 41 is reciprocatingly pumped into the heating box 33 through the ink discharge tube 43, so that the ink can circulate in the ink cartridge 35, the ink extraction tube 42, the suction cylinder 41, the ink discharge tube 43, the heating box 33 and the ink delivery channel 37; When the driving rod 46 rotates, the transmission rod 53 is driven to rotate through the synchronous wheel 61 and the synchronous belt 62, and the gear 52 is further driven to rotate periodically through the arc-shaped tooth groove 54, so that the cleaning brush plate 56 can be periodically rotated counterclockwise, and under the elastic force of the spring 58, it is periodically rotated clockwise to return to the initial position, and the reciprocating swing of the cleaning brush plate 56 has a cleaning effect on the ink coating port 2; After the hot air generated by the vortex tube 32 passes through the heating box 33 to heat the ink, it will flow back to the intersection box 71 through the hot air exhaust pipe 73. After the cold air generated by the vortex tube 32 cools the ink coating port 2, it will flow back to the intersection box 71 through the cold air exhaust pipe 72, so that the hot and cold air in the intersection box 71 meet to generate condensed water beads, and the condensed water beads are transported to the arc-shaped water storage cylinder 76 through the inclined water filter plate 74 and the drainage channel 75, so that the cleaning brush plate 56 can enter the arc-shaped water storage cylinder 76 for cleaning every time it rotates clockwise to reset; During marking, the material to be marked is evenly fed onto a feed belt (not shown) through a vibrating plate 11, and then the material to be marked is marked by a marking head 12. After marking, the position of the paper or label is detected by a camera or sensor built into a visual head 13. During the marking process, the pushing component 14 pushes the paper or label from the feed tray to the printing area, and the magnetizing component 15 uses magnetic materials or magnetic force to fix and stabilize the position of the label or paper during the printing process.
