Description

[0002] The nozzle is the core component of the spraying device, and its structural design is directly related to the spraying efficiency and quality. The design key points of the nozzle include multiple aspects such as the size, material, shape of the nozzle, and the spraying control system. The nozzle size determines the spraying range and effect. Generally speaking, the larger the nozzle size, the wider the spraying range, but the particles will be larger; on the contrary, the smaller the nozzle size, the finer the spraying particles, which is suitable for fine spraying scenarios. The materials of the nozzle usually include plastics, metals, ceramics, etc., and different materials are suitable for different spraying environments and requirements.

[0003] In the prior art, most of the spraying nozzle structures of inkjet devices do not have a nozzle protection mechanism. During the printing process, the nozzle directly contacts the surface of the material. If there are uneven protrusions on the material passing through the nozzle, it will cause damage to the nozzle, reducing the service life of the nozzle and the printing quality. Summary of the Utility Model

[0008] As a further description of the above technical solution:

[0009] The limiting plate is slidably connected inside the nozzle seat, and the spray pipe penetrates through the bottom end of the nozzle seat.

[0010] As a further description of the above technical solution:

[0011] One end of the torsion spring is fixedly connected inside the U-shaped frame, and the other end of the torsion spring is fixedly connected to the outside of the rotating shaft.

[0012] As a further description of the above technical solution:

[0020] The utility model has the following beneficial effects:

[0021] 1. In the present utility model, ink is transported to the nozzle through a nozzle tube for printing operations. The heating tube outside the nozzle tube heats the ink. There may be unevenness in the materials above the inkjet device. During the transportation of the materials, the flattening plate will contact the printing position before the nozzle. The connecting rod rotates the rotating shaft, and under the torsion of the torsion spring, the flattening plate always adheres to the surface of the printing material. If the uneven part passes through the position of the nozzle, the nozzle will be slightly lifted by the limiting plate, and at the same time, the return spring is compressed. The return spring rebounds to reset the nozzle, achieving the effect of protecting the nozzle through the flattening plate and the nozzle telescopic mechanism. It can effectively prevent the nozzle from being damaged during printing, extend the service life of the nozzle, and improve the printing quality.

[0022] 2. In the present utility model, after stopping the printing operation, the blower is started to quickly discharge the hot air in the heating tube. There will be dust passing through during the air extraction process of the blower. These dusts are filtered by the filter screen. When the filter screen needs to be cleaned, the push-pull ring is pulled upward to disengage the pin rod from the filter screen, and at the same time, the compression spring is compressed through the limiting block. After cleaning, the filter screen is reinstalled. When the push-pull ring is released, the compression spring rebounds to make the pin rod engage with the filter screen again, achieving the effect of quickly dissipating heat through the blower. At the same time, the filter screen is convenient to remove, and it can be cleaned in time, improving the cleaning and heat dissipation effect and the practicability of the device.

[0033] Refer to Figure 4 - Figure 6, the heat dissipation mechanism includes two mounting brackets 14 which play a connecting role. The bottom ends of the two mounting brackets 14 are fixedly connected to the top end of the mounting base 1. A blower 15 is fixedly connected between the two mounting brackets 14, and the blower 15 plays a role in heat dissipation.
