Description

Technical Field

[0001] This utility model relates to the field of inkjet printer printhead technology, specifically to a dustproof and heat dissipation linkage mechanism for a dual-table inkjet printer printhead. Background Technology

[0002] Inkjet printers are non-contact digital printing equipment that precisely sprays tiny ink droplets onto media such as paper, film, metal, and ceramics through piezoelectric or thermal inkjet nozzles. They are suitable for continuous production of multiple materials, colors, and tasks, eliminating the need for plate making, reducing waste and emissions, and are widely used in industries such as labeling, packaging, electronics, textiles, and advertising.

[0003] In actual operation, the high-frequency operation of the printhead generates concentrated heat. Traditionally, the temperature drops slowly due to natural heat dissipation from the outer casing, which can easily lead to nozzle blockage or ink droplet deviation due to overheating. When the machine is stopped, the printhead is exposed, and workshop dust and ink volatiles can easily adhere to the nozzles, resulting in stringing and ink shortage defects when the machine is restarted. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a dustproof and heat dissipation linkage mechanism for the printhead of a dual-table inkjet printer, including a mounting box, a printhead mounted on the bottom of the mounting box, a cover fixedly connected to the printhead by screws, a heat dissipation component fixedly connected to the surface of the mounting box, and a dustproof component fixedly connected to the bottom of the heat dissipation component.

[0005] The heat dissipation assembly includes a mounting bracket, a mounting plate is fixedly connected to the inner wall of the mounting bracket, a cooling fan is fixedly connected to the inside of the mounting plate by screws, a mounting plate is fixedly connected to the surface of the mounting box, a heat-conducting plate is fixedly connected to the left end of the mounting plate, a heat dissipation fin is fixedly connected to the top of the heat-conducting plate, and bolts are fitted inside the mounting bracket.

[0006] The above technical solution utilizes a combination of heat-conducting plates and heat dissipation fins in the heat dissipation component to quickly dissipate the heat generated by the nozzle and force it to be cooled by a cooling fan, thus achieving active heat dissipation.

[0007] As a further improvement to the above solution, the number of fixing plates is set to two, and the two fixing plates are symmetrically distributed around the center of the front of the heat-conducting plate. The number of heat-conducting plates is set to four, and the four heat-conducting plates are distributed in a circular array around the top of the mounting box.

[0008] The above technical solution uses two symmetrically distributed fixed plates to support four circumferentially arrayed heat-conducting plates, allowing heat to be evenly dissipated from the nozzle to the surrounding area, thus avoiding localized overheating.

[0009] As a further improvement to the above solution, the bolts pass through the mounting box, and the nozzle and fixing bracket are threaded and fixed to the surface of the mounting box. The heat-conducting sheet and heat dissipation fins are made of copper sheets.

[0010] Through the above technical solution, the design of bolts penetrating the mounting box, nozzle and fixing frame, the threaded fastening ensures the temperature stability between the components and resists the risk of loosening caused by equipment vibration. Copper heat-conducting plates and heat dissipation fins are used to take advantage of the high thermal conductivity of copper to significantly reduce thermal resistance and accelerate the transfer of heat from the nozzle to the heat dissipation fins.

[0011] As a further improvement to the above solution, the dustproof component includes a mounting platform, a cylinder is fixedly mounted on the inner wall of the mounting platform, a dustproof cover is fixedly connected to the output end of the cylinder, a baffle is fixedly connected to the right end of the dustproof cover, a sealing hole is opened at the right end of the dustproof cover, and a sealing block is fixedly connected to the bottom of the mounting box.

[0012] Through the above technical solution, the movement of the dust cover driven by the cylinder is achieved, which realizes the active shielding of the nozzle by the dust cover. The design of the dust cover and the sealing block forms a physical barrier when not in operation, effectively isolating dust particles in the environment and preventing them from adhering to the nozzle surface or clogging the nozzle.

[0013] As a further improvement to the above solution, the mounting platform is fixedly connected to the bottom of the mounting frame, and the dust cover is slidably connected to the bottom of the mounting box.

[0014] As a further improvement to the above solution, two sealing holes are provided, which are symmetrically distributed around the center of the right end surface of the dust cover, and the diameter of the sealing holes is the same as the diameter of the sealing block.

[0015] By using the above technical solution, two symmetrically distributed sealing holes are set, and their diameters match those of the sealing block, ensuring the airtightness of the dust cover when it is closed.

[0016] As a further improvement to the above solution, the dust cover is fixedly connected to both the front and rear of an extended side plate, and the surface of the extended side plate is provided with a sliding hole, and a sliding column is slidably connected inside the sliding hole.

[0017] The above technical solution, through the combination of extended side plates and sliding holes and sliding columns, provides lateral support for the dust cover, preventing it from deforming during movement.

[0018] As a further improvement to the above solution, the left and right ends of the sliding column are fixedly connected to the inner wall of the mounting platform.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention utilizes a heat dissipation assembly consisting of a heat-conducting plate, heat dissipation fins, and a cooling fan. When the nozzle generates heat, the heat is conducted through the outer shell of the mounting box to the surface of the heat-conducting plate, and then the heat-conducting plate transfers the heat to the heat dissipation fins. When the cooling fan is activated, the airflow it generates forces the heat dissipation fins to cool them, accelerating the heat diffusion and dissipation, thereby achieving efficient heat dissipation of the nozzle and maintaining a stable operating temperature.

[0021] This invention features a dustproof assembly consisting of a cylinder, a dust cover, and a sealing block. When the printhead is not in use, the cylinder drives the dust cover to slide towards the printhead, allowing the printhead to be completely enclosed inside the dust cover. The sealing block and the sealing hole work together to form a sealed space, effectively preventing external dust from entering the printhead area, avoiding dust accumulation that could affect printing accuracy, and ensuring printhead cleanliness.

[0030] The heat dissipation assembly 4 includes a mounting bracket 41, a mounting plate 42 is fixedly connected to the inner wall of the mounting bracket 41, a cooling fan 43 is fixedly connected to the inside of the mounting plate 42 by screws, a mounting plate 44 is fixedly connected to the surface of the mounting box 1, a heat-conducting plate 45 is fixedly connected to the left end of the mounting plate 44, a heat dissipation fin 46 is fixedly connected to the top of the heat-conducting plate 45, and a bolt 47 is sleeved inside the mounting bracket 41.

[0031] During use, the heat generated by the nozzle 2 is transferred through the outer shell of the mounting box 1 to the surface of the heat-conducting plate 45, and then through the heat-conducting plate 45 to the surface of the heat dissipation fins 46. The cooling fan 43 is turned on, and the airflow generated by the cooling fan 43 blows the heat dissipation fins 46, causing the heat on the surface of the heat dissipation fins 46 to be carried away by the airflow, and at the same time, the temperature of the nozzle surface is reduced, thus performing heat dissipation work.

[0032] There are two fixing plates 44, which are symmetrically distributed around the front center of the heat-conducting plate 45. There are four heat-conducting plates 45, which are arranged in a circular array on the top of the mounting box 1.

[0033] Bolt 47 passes through mounting box 1, nozzle 2 and fixing bracket 41 and is threaded onto the surface of mounting box 1. The heat conduction plate 45 and heat dissipation fin 46 are made of copper.

[0034] The dustproof component 5 includes a mounting platform 51, a cylinder 52 is fixedly mounted on the inner wall of the mounting platform 51, a dust cover 53 is fixedly connected to the output end of the cylinder 52, a baffle 54 is fixedly connected to the right end of the dust cover 53, a sealing hole 55 is opened at the right end of the dust cover 53, and a sealing block 56 is fixedly connected to the bottom of the mounting box 1.

[0035] When in use, start cylinder 52. The output end of cylinder 52 drives the dust cover 53 to move towards the nozzle position, so that the nozzle enters the interior of the dust cover 53. The sealing block 56 enters the interior of the dust cover 53 through the sealing hole 55 to seal the nozzle 2 and perform dust prevention.

[0036] Mounting platform 51 is fixedly connected to the bottom of mounting bracket 41, and dust cover 53 is slidably connected to the bottom of mounting box 1.

[0037] There are two sealing holes 55, which are symmetrically distributed around the center of the right end surface of the dust cover 53. The diameter of the sealing hole 55 is the same as the diameter of the sealing block 56.

[0038] The dust cover 53 is fixedly connected to the front and rear with extension side plates 6. The surface of the extension side plate 6 is provided with sliding holes 7, and the sliding holes 7 are slidably connected with sliding columns 8.

[0039] The left and right ends of the sliding column 8 are fixedly connected to the inner wall of the mounting platform 51.

[0040] The implementation principle of the dustproof and heat dissipation linkage mechanism of the dual-table inkjet printer printhead in this embodiment is as follows: when the inkjet printer is in use, the heat generated by the printhead 2 is transferred to the surface of the heat-conducting plate 45 through the outer shell of the mounting box 1, and then to the surface of the heat dissipation fins 46 through the heat-conducting plate 45. The cooling fan 43 is turned on, and the airflow generated by the cooling fan 43 blows the heat dissipation fins 46, so that the heat on the surface of the heat dissipation fins 46 is carried away by the airflow, and at the same time, the temperature of the printhead surface is reduced, thus performing heat dissipation work.

[0041] When the nozzle is not in use, the cylinder 52 is activated by the dustproof component 5. The output end of the cylinder 52 drives the dustproof cover 53 to move towards the nozzle position, so that the nozzle enters the interior of the dustproof cover 53. The sealing block 56 enters the interior of the dustproof cover 53 through the sealing hole 55 to seal the nozzle 2 and perform dustproof work.

[0042] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
