Description

Technical Field

[0001] This utility model relates to the field of printer printhead heat dissipation technology, specifically a heat dissipation structure for a digital inkjet printer printhead. Background Technology

[0002] A printing press is a machine for printing text and images. A modern printing press generally consists of mechanisms for plate mounting, inking, printing, and paper feeding (including folding). Its working principle is as follows: First, the text and images to be printed are made into a printing plate, which is then mounted on the printing press. Then, ink is applied to the areas of the printing plate containing the text and images by hand or by the printing press. The ink is then transferred directly or indirectly to paper or other printing substrates (such as textiles, metal plates, plastics, leather, wood, glass, and ceramics), thereby reproducing a printed product identical to the printing plate.

[0003] Patent document with patent publication number "CN220700742U" discloses a printing press nozzle and a heat dissipation structure, wherein the heat dissipation structure is disposed on the surface of the printing press nozzle; the heat dissipation structure includes a heat dissipation and cooling sleeve fitted on the surface of the printing press nozzle, and a storage chamber is provided inside the heat dissipation and cooling sleeve, and the storage chamber is filled with refrigerant.

[0004] This patent achieves efficient heat dissipation for digital inkjet printer printheads. Existing digital inkjet printer printheads require heat dissipation during use, and existing heat dissipation structures are usually integrated structures that are directly mounted on the printhead. After long-term use, the heat dissipation structure needs to be maintained, and this installation method is very inconvenient. Utility Model Content

[0027] Please see Figures 1-5The heat dissipation structure of this digital inkjet printer printhead offers two technical solutions:

[0028] The first embodiment includes a printer printhead body 1, and a heat dissipation mechanism is provided on the outside of the printer printhead body 1. The heat dissipation mechanism can be quickly installed and removed. The heat dissipation mechanism includes:

[0029] The mounting assembly 3 has multiple sets arranged along the splicing direction of the two heat conduction boxes 21. The mounting assembly 3 includes a square box 31. Pull plates 32 are slidably connected to both sides of the square box 31. A rack 33 is fixedly connected to the side of the two pull plates 32 that are close to each other, and the two racks 33 are staggered. A rotating rod 34 is rotatably connected to the surface of the square box 31 away from the printer nozzle body 1. A gear 35 is fixedly connected to the end of the rotating rod 34 located inside the square box 31. Both racks 33 mesh with the rotating rod 34 and rotate. A fixing post 36 is fixedly connected to one side of each of the two heat conduction boxes 21. A limiting assembly 4 is also provided on the square box 31 to prevent the gear 35 from reversing.

[0030] The heat dissipation assembly 2 includes two heat conduction boxes 21 on the left and right, a water flow box 22, a fan 23 and a water pump 24. The two heat conduction boxes 21 are provided with two front and rear connecting ports on the side that is close to each other. A square boss 26 is fixedly connected to the inner wall of the connecting port of the left heat conduction box 21 for engaging with the connecting port.

[0031] The water flow box 22 is installed on the side wall of the heat conduction box 21 away from the printer nozzle body 1, and the fan 23 is installed on the side wall of the water flow box 22 away from the heat conduction box 21.

[0032] The water pump 24 is fixedly connected to the top of the heat conduction box 21 and is connected to the water flow box 22 and the heat conduction box 21 respectively through connecting pipes. Multiple heat conduction plates 25 are fixedly connected at equal intervals on the inner wall of the heat conduction box 21.

[0033] The two heat conduction boxes 21 in the heat dissipation assembly 2 are wrapped around the outside of the printer printhead, and the two heat conduction boxes 21 are tightened by the mounting assembly 3, so that the heat dissipation assembly 2 is installed on the printer printhead. This allows for quick operation after the heat dissipation mechanism needs to be installed or disassembled, improving the convenience of using the device.

[0034] The limiting component 4 includes a groove 41 formed on the front of the square box 31. A slider 42 is slidably connected to the inner surface of the groove 41. An L-shaped positioning rod 43 is fixedly connected to the front of the slider 42. Multiple positioning grooves 44 are formed at equal intervals along the circumference on the surface of the rotating rod 34. The positioning grooves 44 cooperate with the L-shaped rod 43 to fix the relative posture of the rotating rod 34 and the square box 31.

[0035] The pull plate 32 has an oblong hole, and the fixing post 36 is slidably disposed in the oblong hole; when the pull plate 32 moves relative to the square box 31, the fixing post 36 abuts against the inner wall of the oblong hole, and plays a guiding role.

[0036] The edge of the pull plate 32 has a sliding protrusion, and the inner sidewall of the square box 31 has a sliding groove; the sliding protrusion is disposed in the sliding groove and can slide relative to it.

[0037] When installing the two heat-conducting boxes 21, the position of the gear 35 after rotation is limited by the limiting component 4 to prevent reverse rotation, thereby ensuring the stability after installation.

[0038] In use, the two heat-conducting boxes 21 are closed and wrapped around the outside of the printer head body 1, and the two pull plates 32 are respectively fitted onto the outside of the two fixed posts 36. The rotating rod 34 is rotated, which causes the gear 35 to rotate. The gear 35 rotates and engages with the two racks 33, thereby tightening the two fixed posts 36, thus completing the installation of the two heat-conducting boxes 21. After the gear 35 stops rotating, the slider 42 is pushed to move, so that the L-shaped positioning rod 43 enters the interior of the positioning groove 44, thereby preventing the rotating rod 35 from reversing.
