Description

Technical Field

[0001] This utility model relates to the field of heat shrink tubing manufacturing technology, specifically a printing mechanism for heat shrink tubing used in new energy vehicles. Background Technology

[0002] Heat shrink tubing is a tubular material with heat shrinking properties. Common materials for heat shrink tubing include polyolefins, fluoroplastics, and silicone, and the characteristics and application scenarios of heat shrink tubing of different materials are also different. Heat shrink tubing for new energy vehicles is mainly used in battery systems, motor drive systems, charging systems, and vehicle electronic systems.

[0003] Chinese Patent Publication No. CN 210590151 U discloses a heat shrink tubing printing machine, which includes a support frame, a geared motor and an ink cartridge respectively mounted on the support frame, a printing wheel mounted on the output end of the geared motor and with its lower end located inside the ink cartridge, a pressure roller mounted directly above the printing wheel, a height adjustment mechanism mounted on the support frame for adjusting the distance between the pressure roller and the printing wheel, and a limiting mechanism respectively mounted on both sides of the upper end of the printing wheel to prevent the heat shrink tubing from shifting.

[0004] The aforementioned heat shrink tubing printing machine uses a printing wheel to print on the heat shrink tubing. However, the width of the printing wheel is greater than the diameter of the heat shrink tubing. After the printing wheel is immersed in ink, the outer surface of the printing wheel will be completely covered with ink. The printing wheel only needs ink for the part of the heat shrink tubing that is being printed. If the ink on the remaining part is left to adhere to the outer surface, the excess ink will be transferred onto the heat shrink tubing, resulting in a difference between the printed pattern on the heat shrink tubing and the intended pattern.

A drive pulley 15 is provided below the driven pulley 14, and the drive pulley 15 is connected to the driven pulley 14 through a belt 16. The drive pulley 15 is coaxially fixedly connected to the output shaft of the reducer 17, and the input end of the reducer 17 is fixedly connected to the output shaft of the motor 18.

[0036] The outer side of the connecting shaft 22 is threaded, and both sides of the pressure roller 21 are provided with positioning nuts 23, and both positioning nuts 23 are threadedly connected to the connecting shaft 22.

[0037] The lifting seat 24 is provided with a top plate 25 above it, and the two ends of the top plate 25 are respectively provided with through holes for the slide rod 28 and the handle bolt 29 to pass through; the bottom of the side of the top plate 25 away from the pressure roller 21 is fixedly connected to the upright plate 26.

[0038] The top of the handle bolt 29 is rotatably connected to the top of the support plate 9; the bottom of the slide rod 28 is fixedly connected to the top of the fixed seat 27, and the bottom of the fixed seat 27 is fixedly connected to the top of the support plate 9.

This not only prevents ink waste but also ensures the normal operation of the heat shrink tubing printing process. In addition, by rotating the handle bolt 29, the pressure roller 21 can be moved vertically, thereby changing the distance between the pressure roller 21 and the printing wheel 11.

[0044] By adopting the above technical solution, the rotating shaft 31 can be rotated by rotating the adjusting rod 32, thereby allowing the scraper 33 to rotate and change position. This ensures that the scraper 33 is in close contact with the printing wheel 11 and prevents the scraper 33 from affecting the normal rotation of the printing wheel 11. By rotating the handle bolt 2 36, the bottom of the handle bolt 2 36 is pressed against the limiting plate 34, which prevents the scraper 33 from shifting.

[0045] The working principle of this utility model is as follows: the scraper plate 33 can scrape the outer surface of the printing wheel 11, thereby scraping away all the excess ink on the outer surface of the printing wheel 11, preventing excess ink from being carried to the heat shrink tubing by the printing wheel 11. This not only prevents ink waste but also ensures the normal operation of the heat shrink tubing printing process. In addition, by rotating the handle bolt 29, the pressure roller 21 can be moved vertically, thereby changing the distance between the pressure roller 21 and the printing wheel 11. This allows the printing wheel 11 to print on heat shrink tubing of different diameters, and also ensures that the pressure roller 21 always maintains a state of pressing the heat shrink tubing, so that the heat shrink tubing can be tightly attached to the surface of the printing wheel 11, ensuring that the ink can be printed smoothly on the heat shrink tubing.

[0046] Rotating the adjusting rod 32 can drive the rotating shaft 31 to rotate, thereby causing the scraper 33 to rotate and change position. This ensures that the scraper 33 is in close contact with the printing wheel 11 and prevents the scraper 33 from affecting the normal rotation of the printing wheel 11. Rotating the handle bolt 36 allows the bottom of the handle bolt 36 to press against the limiting plate 34, preventing the scraper 33 from shifting.

[0047] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
