Description

Technical Field

[0001] The utility model belongs to the technical field of printing equipment, in particular to a printing screen and a printing screen component. Background Art

[0002] Screen printing is a multi-purpose printing technology that can copy images onto substrates through ink transfer. Screen printing is not only suitable for general paper printing, but also has a wide range of adaptability. For example: ceramics, glass, printed circuit boards, etc. Depending on the texture of the substrate, the printing is different. Although there is an inseparable internal connection between each series, due to the different textures of the substrates (that is, different chemical and physical properties), each has its own particularity. Therefore, people usually divide it into several categories according to different substrates: paper printing, plastic printing, ceramic printing, glass printing, circuit board printing, metal printing, textile printing, etc.

[0003] Existing screen printing generally uses a printing screen composed of a screen frame and a silk screen for printing. The common production of the screen frame is generally welded into an integrated structure by special workers using aluminum materials. Therefore, ordinary operators cannot produce according to the different requirements of the specifications and sizes of each printed product, so users need to prepare multiple printing screens, which not only takes up a lot of space, but also causes high production costs.

[0008] The connecting rod is fixed to the first connecting member and the second connecting member by long screws;

[0009] The wire mesh is adhered to the upper end of the mesh frame by adhesive.

[0010] Preferably, the mesh frame is in a rectangular structure or a square structure.

[0011] Preferably, both side ends of the connecting rod are provided with slots, and the side end of the connecting rod located at each slot is further provided with a first threaded hole, the first threaded hole passes through the slot horizontally, and the first threaded hole is arranged perpendicular to the slot.

[0012] Preferably, the first connecting member is in an L-shaped structure, both ends of the first connecting member are fixedly connected with first clamping blocks, and a second threaded hole is formed at a side end of the first clamping block.

[0013] Preferably, the second connecting member is of I-type structure, both ends of the second connecting member are fixedly connected with second clamping blocks, and the side ends of the second clamping blocks are provided with third threaded holes.

[0014] Preferably, the first threaded hole, the second threaded hole and the third threaded hole are all compatible with the long screw, and the first threaded hole, the second threaded hole, the third threaded hole and the long screw meet the thread self-locking condition, that is, the thread lead angle is less than the equivalent friction angle.

[0015] A printing screen assembly includes the printing screen described above.

[0016] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0017] Fixed connection: refers to a connection in which parts or components are fixed without any relative movement. It is divided into detachable connection and non-detachable connection.

[0018] (1) Removable connection: The parts are fixed together by screws, splines, wedge pins, etc. This connection method can be disassembled for maintenance without damaging the parts. However, the specifications of the connectors used must be correct (such as the length of the bolts, keys, and wedge pins) and they must be properly tightened.

[0019] (2) Non-detachable connection: mainly refers to welding, riveting and tenoning. Since forging, sawing or oxygen cutting are required for disassembly during maintenance or replacement, spare parts generally cannot be reused. At the same time, attention should be paid to process quality, technical inspection and remedial measures (such as calibration, polishing, etc.) during connection.
