Description

Technical Field

[0001] The utility model relates to the field of flat screens, in particular to a flat screen for foaming machinery. Background Art

[0002] In foaming machinery, a flat mesh is needed as a template, which can not only use the mesh holes on the flat mesh for ventilation, but also prevent the foaming particles from leaking out through the mesh holes.

[0003] There are generally two types of flat mesh structures. One is to drill holes in the aluminum plate for ventilation. However, in order to avoid leakage of foamed particles, the diameter of the holes is very small, and densely distributed holes cannot ensure sufficient ventilation, which can easily lead to insufficient ventilation. The other is to cross-weld support strips and filter strips to form a structure with long mesh holes, which can ensure sufficient ventilation. However, the welding points of the support strips and filter strips are too thick, and it is easy to open the weld during use. After opening the weld or partial deformation of the filter strips, it is difficult to maintain and needs to be improved. Utility Model Content

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

[0018] See also Figure 1~Figure 3 , the utility model embodiment includes:

[0019] like Figure 1 and Figure 2The flat mesh for foaming machinery shown includes: support strips 2, core wires 3 and filter strips 1. The support strips 2 are arranged in parallel and at intervals in the same plane to form a back plate, and the filter strips 1 are arranged in parallel and at intervals on the front of the back plate to form a mesh plate. The filter strips 1 are perpendicular to the support strips 2 to form a long mesh structure, thereby ensuring the ventilation volume.

[0020] like Figure 3 As shown, a positioning groove 6 corresponding to the filter strip 1 is concavely arranged on the surface of the support strip 2 that is connected to the filter strip 1. The portion of the filter strip 1 that is connected to the support strip 2 enters the positioning groove 6 for positioning during assembly, thereby improving assembly accuracy and avoiding the problem of excessive gaps.

[0021] In this embodiment, the support bar 2 and the filter bar 1 are respectively made of stainless steel bars, which have good corrosion resistance and stable structure. The cross-sections of the support bar 2 and the filter bar 1 are respectively trapezoidal. Figure 2 and Figure 3 As shown, the large flat side of the filter strip 1 is located on the front side of the flat net, has good flatness, allows ventilation through the gap between two adjacent filter strips 1, and limits the entry of foamed particles.

[0022] A first positioning hole 10 penetrating the positioning groove 6 is provided in the support strip 2 along the length direction, and the core wire 3 is provided in the first positioning hole 10 and penetrating the corresponding filter strip 1. In this embodiment, a second positioning hole 9 corresponding to the first positioning hole 10 is provided on the filter strip 1. The core wire 3 is inserted into the first positioning hole 10 and the second positioning hole 9 to lock the filter strip 1 in the positioning groove 6 to prevent it from falling off. The structure is stable, and no welding is required, thus avoiding the problem of open welding. During use, if part of the filter strip 1 is deformed or damaged, it can be unlocked by pulling out the core wire 3, which is convenient for replacement.

[0023] The core wire 3 is a stainless steel wire. In this embodiment, the core wire 3 is a stainless steel wire with a diameter of 1 mm, which is corrosion-resistant and has good shear resistance. In order to prevent the axial movement of the core wire 3, cover plates 4 are provided at both ends of the support bar 2 to limit the core wire 3, and the structure is reliable.

[0024] like Figure 3 As shown, a blind hole 8 corresponding to the end of the core wire 3 is provided on the inner side of the cover plate 4, and the end of the core wire 3 is positioned through the blind hole 8, and the cover plate 4 is positioned by the end of the core wire 3 to avoid twisting of the cover plate 4. A countersunk hole 7 is provided on the cover plate 4, and a screw 5 connected to the support bar 2 is provided in the countersunk hole 7, which is convenient for disassembly and assembly.
