The filter screen in the filter of the application adopts a detachable fixing structure, so that the filter screen is not firmly fixed by a built-in stainless steel net, and is easy to deform under long-term working compression, and the defect of easy leakage exists.
Disclosure of Invention
The present utility model is directed to the above-described problems, and provides an ink head prefilter in which an inner core can be reliably fixed, and stable operation can be maintained without causing leakage due to deformation.
The utility model adopts the following technical scheme: the utility model provides an ink head prefilter, includes the casing, sets up the inner core in the casing, its characterized in that casing and inner core be welded fastening, the inner core include vertical strengthening rib frame, vertical strengthening rib frame in the fixed stainless steel mesh of secondary rubber coating injection molding.
Preferably, the stainless steel net is a 316L stainless steel twill mat net.
Preferably, the housing is provided with variable inserts at the inlet and outlet, respectively.
Preferably, the side part of the shell is provided with an extraction opening, and the extraction opening is provided with an extraction opening insert.
Preferably, the shell is provided with welding ribs at the position of the outlet cover, and the inner core is provided with inner core welding ribs matched with the welding ribs.
The utility model has the beneficial effects that:
1. the inner core and the shell are welded and fixed by the preset welding ribs, so that the inner core is ensured to be fixed and stable, the reliability of long-term operation is ensured, and leakage caused by deformation easily caused by long-term compression is avoided.
2. The stainless steel net is fixed in a mode of injection molding and secondary encapsulation, is reliable in fixation, and adopts the stainless steel net with good pressure resistance, so that the pressure bearing and deformation preventing effects are improved.
3. The inlet and outlet of the filter are designed with variable inserts, and the inlet and outlet can be replaced according to the use requirement of a customer;
4. the side extraction opening is additionally arranged on the shell, and can be adopted for exhausting under the condition that the air in the ink needs to be exhausted.

Detailed Description
The utility model will be further illustrated with reference to specific examples.
Example 1: as shown in fig. 1-4, an ink head prefilter comprises a shell 7, wherein an inner core is arranged in the shell, the shell 7 and the inner core are welded and fixed, the inner core comprises a longitudinal reinforcing rib frame 2, and a stainless steel net 1 is fixed in the longitudinal reinforcing rib frame 2 through secondary encapsulation and injection molding. Wherein, casing 7 presets welding muscle 5 in the export lid position, and the inner core sets up the inner core welding muscle 3 that matches with the welding muscle. The welding ribs are mutually welded by hot melting, so that the inner core is reliably fixed in the shell. The leakage problem caused by deformation cannot be easily generated.
Specifically, the stainless steel net 1 is a 316L stainless steel twill mat net. The stainless steel net with the structure has reliable and stable bearing performance and compression resistance.
Specifically, the housing 7 is provided with inlet inserts 8 at the inlet and outlet inserts 6 at the outlet, respectively. The insert is of a variable structure, and the inlet and the outlet can be replaced according to the use requirement of a customer.
In addition, in this embodiment, for the case of exhausting the gas in the ink, a side exhaust port may be used for exhausting; therefore, an extraction opening is arranged on the side part, and an extraction opening insert 4 is arranged at the extraction opening. The suction port insert 4 is also a variable insert, and can be replaced according to the use requirements of customers.
Example 2:
as shown in fig. 5 and 6, the embodiment is different from embodiment 1 in that a suction port bulkhead is provided on the side of the housing to reliably seal the side suction port. The structure change can be realized by additionally arranging the extraction opening insert 4 according to the requirement, the requirement of side extraction is met, and the device is very flexible.
It is to be understood that these examples are illustrative of the present utility model and are not intended to limit the scope of the present utility model. Further, it is understood that various changes and modifications may be made by those skilled in the art after reading the teachings of the present utility model, and such equivalents are intended to fall within the scope of the claims appended hereto.
