Description

Technical Field

[0001] This utility model relates to the field of dispensing head substrates, specifically a wear-resistant dispensing head substrate structure. Background Technology

[0002] Traditional dispensing head substrates are mostly made of integral aluminum alloy (6061-T6), which makes the dispensing head substrate easy to be worn by metal particles during use. That is, when the colloid containing metal fillers (such as silicon carbide and alumina) flows under high pressure, the wear rate of the inlet / outlet can reach 0.1mm / thousand cycles, and the flow channel is prone to deformation, which in turn greatly shortens the substrate life.

[0003] To address the aforementioned issues, a wear-resistant dispensing head substrate structure is proposed here. Utility Model Content

Several connecting blocks engage with several connecting slots to facilitate the initial positioning of the two annular seats. Two fixing bolts are fixed to the threads of the two second threaded holes to further position the two annular seats, thereby ensuring the stable operation of the two first coarse filters and the two second coarse filters. The cooperation between the two first coarse filters and the two second coarse filters facilitates the filtration of colloids and materials.

[0007] Preferably, the tungsten carbide glue inlet is connected to the first flow channel, and the tungsten carbide feed inlet is connected to the second flow channel. The glue is introduced into the first flow channel through the tungsten carbide glue inlet, and the material is introduced into the second flow channel through the tungsten carbide feed inlet.

[0012] Preferably, the pore diameter of the second coarse filter screen is larger than that of the first coarse filter screen. The combination of two first coarse filters and two second coarse filters facilitates the filtration of colloids and materials.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The substrate is made of aluminum alloy, which reduces material costs. Tungsten steel nests are provided in the glue outlet, discharge outlet, first flow channel, and second flow channel.
