Technical Field

[0001] The utility model relates to the technical field of digital printing machines, in particular to a nozzle anti-collision device for a digital printing machine. Background Art

[0002] Inkjet digital printing machine is a non-contact inkjet printing type high-tech digital printing equipment, so it is not restricted by any materials and can perform color photo-level printing on surfaces such as wood, glass, crystal, metal plates, floor tiles, ceramic tiles, CDs, acrylic, plexiglass, leather, silicone, plastic, PP, PE, PVC, cloth, self-adhesive stickers, stone, etc.

[0003] In the existing technology, most digital printing machines use nozzles to print on the surface of the material. However, during the printing process, the material may become wrinkled or uneven, causing the nozzle to directly contact the material surface. Since the nozzle is usually very delicate and fragile, this contact may cause damage to the nozzle, thereby affecting the printing quality.

[0004] Therefore, those skilled in the art provide a nozzle anti-collision device for a digital printing machine to solve the problems raised in the above background technology. Utility Model Content

When in use, the device sets a roller to roll on the surface of the material before the nozzle prints, and uses a sliding rod to slide inside the connecting plate. The laser rangefinder at the upper end of the sliding rod monitors the distance change between the fixed plate in real time, thereby controlling the corresponding electric telescopic rod to adjust the height of the nozzle, ensuring that the nozzle maintains an appropriate distance from the material surface, effectively avoiding the collision of the material with the nozzle during printing, thereby improving the printing quality and protecting the nozzle from damage.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

Obviously, the specific embodiments described are only part of the specific embodiments of the present invention, not all of the specific embodiments. Based on the specific embodiments of the present invention, all other specific embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1-5 , a specific embodiment of the present invention provides: a nozzle anti-collision device for a digital printing machine, comprising a workbench 1 and multiple protective shells 9, a bracket 2 is fixedly connected to the middle part of the upper end of the workbench 1, a hose 3 is evenly spaced at the lower end of the bracket 2, and the lower ends of multiple hoses 3 are fixedly connected to the nozzle 4, an upper end of one side end surface of the bracket 2 is evenly spaced, and the lower ends of the multiple electric telescopic rods 5 are fixedly connected to a connecting plate 6, a spring 7 is provided at the upper end of the inner middle of the multiple connecting plates 6, and a clamping block 8 is fixedly connected to the upper end of the multiple springs 7, and a connecting block 10 is fixedly connected to the upper end of one side of the outer wall of the multiple protective shells 9, and the internal upper ends of the multiple connecting blocks 10 are rotatably connected to a rotating shaft 11, and the upper ends of the multiple rotating shafts 11 are fixedly connected to a protrusion 12, and both sides of the lower ends of the multiple protrusions 12 are provided with a clamping groove 13;

[0032] The upper end of the other end surface of the bracket 2 is fixedly connected to a fixing plate 14, and one side of the inner part of each of the fixing plates 14 is slidably connected to a sliding rod 15. The upper end of each of the sliding rods 15 is provided with a laser rangefinder 16, and the lower end of each of the sliding rods 15 is fixedly connected to a fixing frame 17, and the inner part of each of the fixing frames 17 is rotatably connected to a roller 18;

[0033] When the device is in use, a roller 18 is set to roll on the surface of the material before the nozzle 4 prints, and the sliding rod 15 is used to slide inside the connecting plate, and the laser rangefinder 16 of the sliding rod 15 is used to monitor the distance change between the fixed plate 14 in real time, thereby controlling the corresponding electric telescopic rod 5 to adjust the height of the nozzle 4, ensuring that the nozzle 4 maintains an appropriate distance from the material surface, effectively avoiding the collision of the material with the nozzle 4 during printing, thereby improving the printing quality and protecting the nozzle 4 from damage.

[0034] Multiple hoses 3 all pass through the connecting plate 6 and extend to the lower end of the connecting plate 6 to be fixedly connected with the nozzle 4, and the upper surface of the nozzle 4 is fixedly connected to the connecting plate 6. Through the penetration connection of multiple hoses 3, the fixed connection of the nozzle 4 enhances its stability and reliability, ensuring that the nozzle 4 will not loosen due to vibration or external force during operation, thereby improving the overall printing quality and accuracy. Multiple protective shells 9 are all sleeved on the outside of the nozzle 4, and the upper surface of the protective shell 9 is tightly combined with the connecting plate 6. The protective shell 9 is sleeved on the outside of the nozzle 4 and is tightly combined with the connecting plate 6, effectively preventing external substances from damaging the nozzle 4. The service life of the nozzle 4 is extended and the maintenance frequency is reduced. The multiple blocks 8 are all engaged with the slots 13, which enables the quick installation and disassembly of the protective shell 9 and the nozzle 4, and improves the maintainability of the equipment. The multiple laser rangefinders 16 are kept in a one-to-one correspondence with the electric telescopic rod 5, ensuring that each nozzle 4 can independently and accurately adjust the height, improving the printing accuracy and efficiency.

[0035] Working principle: When the device is in use, the material to be printed enters the lower end of the bracket 2 from one side of the workbench 1. As it enters, the roller 18 is set to roll the surface of the material before the nozzle 4 prints, and the sliding rod 15 is used to slide inside the connecting plate 6. At the same time, the laser rangefinder 16 at the upper end of the sliding rod 15 monitors the distance change between the fixed plate 14 in real time, and then the external controller sends an electrical signal to control the corresponding electric telescopic rod 5 to adjust the height of the nozzle 4, ensuring that the nozzle 4 maintains an appropriate distance from the material surface, effectively avoiding the material from colliding with the nozzle 4 during printing. In addition, the device also protects the nozzle 4 by arranging a protective shell 9 to be sleeved on the outside of the nozzle 4, and stably fixes the protective shell 9 through components such as the connecting block 10, the protrusion 12 and the spring 7, further avoiding direct contact with the nozzle 4 caused by wrinkles or unevenness of the material, and reducing the risk of damage to the nozzle 4. When the nozzle 4 or the protective shell 9 needs to be maintained or replaced, the protective shell 9 can be quickly removed by turning the protrusion 12 without the need for additional tools or complicated operations, which greatly simplifies the maintenance process and improves work efficiency.
