Description

Technical Field

[0001] The utility model relates to the field of composite screen processing, in particular to a screen tensioning device for composite screen processing. Background Technique

[0002] The principle of composite screen processing mainly includes the following aspects: screening principle: using the aperture size of the screen to separate materials with different particle sizes. When the material passes through the screen, particles smaller than the screen hole size pass through the screen, while particles larger than the screen hole size are left on the screen, thus realizing the screening of the material. Vibration principle: The screen is vibrated by a vibration device to increase the fluidity and screen permeability of the material and improve the screening efficiency. Multi-layer screening principle: The composite screen usually consists of multiple layers of screens with different aperture sizes, and fine grading of the material can be achieved through multi-layer screening. In the processing of existing smaller screens, it is necessary to tension the screen to avoid phenomena such as horizontal and vertical wrinkling and inconsistent tension of the screen. The existing screen tensioning devices have complex structures, are difficult to operate, and have low tensioning efficiency, which affects the quality of the screen.

[0003] During the processing of the composite screen, it is necessary to install the screen on the outside of the fixed frame. During the installation process, it is necessary to tension the screen. During the tensioning process, manual methods are generally used for tensioning, resulting in low installation efficiency. Uniform tensioning cannot be carried out during the tensioning process, and wrinkles are likely to occur on the surface after tensioning. Content of the Utility Model

At the same time, a fixed frame is welded and fixed on the outer side of the top plate, and a support column is welded and fixed at the bottom of the end of the fixed frame far from the top plate. A tensioning component is fixedly installed on the top plate. The tensioning component includes a cylinder fixedly installed on the top plate, and a connecting seat is fixedly installed at the end of the piston rod of the cylinder. At the same time, the connecting seat is fixedly installed on the surface of a rubber soft seat, and the rubber soft seat is a lifting structure.

[0006] Preferably, both the limit seat and the screen frame are annularly arranged, and the limit seat and the screen frame are concentric structures. At the same time, the top plate on the surface of the screen frame is an annular structure made of metal material.

[0007] Preferably, five groups of fixed frames are evenly installed on the circumferential outer wall surface of the top plate, and the distance between adjacent two groups of fixed frames is the same. At the same time, support columns with a "T" - shaped cross - section are installed at the bottoms of the five groups of fixed frames.

The piston rod of the cylinder 61 drives the rubber soft seat 65 to move through the connecting seat 63. The rubber soft seat 65 is deformed under pressure and pulls the screen covered on the surface of the limit seat 1 outward. The five groups of cylinders 61 respectively drive the five groups of rubber soft seats 65 to pull outward at five points on the surface of the screen, realizing uniform tensioning of the screen, replacing the manual tensioning method, so that there will be no wrinkles on the surface of the tensioned screen, ensuring the quality of the screen after tensioning and installation; when the five groups of cylinders 61 are working, the top plate 3 is stressed.

At the same time, support columns 5 with a "T" - shaped cross - section are installed at the bottom of the five groups of fixed frames 4.
