AI Technical Summary
The existing tightening polyurethane and rubber composite flexible anti-blocking screens are prone to vibration and out-synchronization when installed multiple times, resulting in gap formation and affecting the material screening effect.
The design of I-shaped reinforcement ribs, protective layer, installation holes, bolts and nuts and U-shaped parts is adopted. The screen main body and connection parts are fixed through bolts and nuts to achieve stable assembly of the screen.
It effectively avoids the leakage of materials from the screen gap, ensuring the stability and consistency of the screening effect.

Description
Technical Field
[0001] The utility model belongs to the technical field of screen meshes, and particularly relates to a novel tensioning type polyurethane and rubber composite flexible anti-clogging hole screen mesh. Background Art
[0002] An anti-clogging hole screen mesh is a screen mesh made of a composite of polyurethane and rubber. The existing tensioning type polyurethane and rubber composite flexible anti-clogging hole screen mesh consists of a tensioning hook and a screen mesh. The tensioning hook is fixed on both sides of the screen mesh with bolts. The screen mesh is composed of a lower polyurethane layer, an upper low-hardness rubber layer and an intermediate cord fabric layer. When this screen mesh is connected to an external installation structure, after installing multiple screen meshes, when the vibrations of the screen meshes are not synchronized, gaps are likely to appear, resulting in materials leaking through the gaps, affecting the material screening effect. Content of the Utility Model
[0003] In order to solve the above technical problems, the utility model provides a novel tensioning type polyurethane and rubber composite flexible anti-clogging hole screen mesh, which can assemble the screen mesh to prevent materials from leaking through the gaps between the screen meshes.
[0004] Specifically, the utility model is achieved through the following technical solutions:
[0005] A novel tensioning type polyurethane and rubber composite flexible anti-clogging hole screen mesh includes a screen mesh main body and a connecting member. The screen mesh main body is composed of a rubber layer, a cord fabric layer and a polyurethane layer arranged in sequence from top to bottom. The connecting member includes an I-shaped reinforcing rib. A protective layer is integrally arranged outside the I-shaped reinforcing rib. Mounting holes are arranged side by side on both sides of the two horizontal parts of the connecting member.
[0006] Preferably, the screen mesh main body is provided with screen holes in a dot matrix pattern.
[0007] Preferably, a U-shaped member is fixedly installed at one end of the screen mesh main body.
[0008] Preferably, tensioning hooks are fixedly installed in sequence on one side of the U-shaped member.
[0009] Preferably, each mounting hole is provided with a bolt and nut in a matching manner.
[0010] Preferably, the positions and distributions of the mounting holes are adapted to the screen holes.
[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:
[0012] 1. In the utility model, the settings of the I-shaped reinforcing rib, the protective layer, the mounting holes and the bolts and nuts are beneficial to assembling the screen mesh and preventing materials from leaking through the gaps between the screen meshes.
[0013] 2. In the present utility model, the U-shaped member and the tension hook are provided, which are conducive to fixing the main body of the screen to the installation part of the external device. BRIEF DESCRIPTION OF THE DRAWINGS
