Problems solved by technology

[0003] Since the 3DP type printer is working, the spraying of liquid from the print head is an intermittent job. It needs to wait for the powder spreader to finish laying before it can start to move and spray. During this waiting time, if the time is too long, or an accident causes the equipment to stop , the print head is in the air and does not spray ink for a long time, the dust in the air will enter the nozzle hole of the print head, or the liquid in the nozzle will solidify and dry up, both of which will block the nozzle hole, affect the continuity of the printing work, and Has a great impact on the life of the print head
[0004] In the existing technology, there is a protection position for the print head on one side of the device, and the print head stops at this position when the work is finished, which plays a role in protecting the print head. However, in practical applications, it is found that the print head often dries up or is blocked. , so the existing protection position can not play a good role in protection

Abstract

The invention provides a printing head with a mobile protection device and printing equipment. The printing head comprises a shell, an ink-jet device and the protection device; and the ink-jet deviceand the protection device are arranged in the shell abreast, the shell is provided with a lower opening, the ink-jet device extends out of the lower opening of the shell for printing work, and the ink-jet device is retracted into the shell to be in contact with the protection device. The spray hole protection device and the ink-jet device are integrated together, and work and do not affect each other; and after the printing head completes the ink-jet action, the printing head is rapidly retracted to the protection device, the protection device can effectively solve the current problem of blockage of spray holes of a nozzle, and the printing head can be protected in time, so that the service life of the printing head and the printing precision of the equipment are greatly improved, and a large guarantee can be provided for the continuity of the equipment work.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a printing head with a moving protection device and printing equipment. Background technique [0002] For 3DP type printers, it is necessary to spread a layer of powder granular material on the working platform with a powder spreader, and then use laser sintering or spraying adhesives to make only the layer of powder covered by the surface of the workpiece slice The area is formed and solidified, so that the workpiece required for accumulation is printed layer by layer. [0003] Since the 3DP type printer is working, the spraying of liquid from the print head is an intermittent job. It needs to wait for the powder spreader to finish laying before it can start to move and spray. During this waiting time, if the time is too long, or an accident causes the equipment to stop , the print head is in the air and does not spray ink for a long time, the dust in the air wil...
