Description

Technical Field

[0001] This utility model relates to the field of screening equipment technology, and more specifically to a floating crossbeam for a tension screen. Background Technology

[0002] A tension screen is a device that achieves efficient screening and anti-clogging by using a flexible screen surface to perform tension and relaxation movements. Its screen surface is made of polyurethane material and is tensioned to the screen walls on both sides by crossbeams.

[0003] The existing tension screens typically have a rigid fixed structure between the crossbeam and the screen wall, which commonly presents the following problems during use: 1) The screen surface is subjected to uneven force during vibration, and stress concentration is easily generated at the connection between the crossbeam and the screen surface, leading to cracking or breakage of the screen surface; 2) The rigid crossbeam results in energy loss during the transmission of vibration, affecting the overall movement amplitude of the screen surface and the screening efficiency; 3) The connection between the crossbeam and the screen surface is prone to loosening or wear due to continuous high-frequency vibration, requiring frequent replacement and maintenance, which increases maintenance costs. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a floating crossbeam for a tension screen, so as to solve the problems in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows.

[0006] A floating crossbeam for a tension screen includes several crossbeams for fixing the screen mesh and screen walls at both ends of the crossbeams. The screen mesh is connected to the crossbeams by quick-release buckles, and a floating support assembly is provided between the crossbeams and the screen walls. The floating support assembly includes floating grooves formed on the screen walls on both sides of the crossbeams. Connectors for fixing the crossbeams are provided in the floating grooves. Rubber springs for supporting the vertical movement of the connectors are provided on the upper and lower sides of the connectors and at the upper and lower ends of the floating grooves.

[0007] The technical solution is further optimized. The quick-release buckle includes a connecting strip that passes through the screen and the crossbeam and a fixing frame that is set at the end of the connecting strip. The two side walls of the fixing frame are respectively provided with snap-fit ​​grooves, and the two side ends of the connecting strip are respectively provided with several sets of snap-fit ​​ends for snapping into the snap-fit ​​grooves.

[0008] To further optimize the technical solution, the snap-fit ​​end is an inclined structure that gradually widens from the end of the connecting strip to the end of the fixed frame, and the end of the snap-fit ​​end is a suspended structure.

[0009] To further optimize the technical solution, a quick-release part is provided on the fixing frame on the outside of the snap-fit ​​groove to allow the snap-fit ​​end to disengage from the snap-fit ​​groove.

[0010] To further optimize the technical solution, two mounting holes are provided at each end of the crossbeam, and mounting holes corresponding to the mounting holes on the crossbeam are provided on the connector. The crossbeam is mounted on the connector by mounting bolts.

[0011] To further optimize the technical solution, a guide rod is provided inside the floating groove to guide the vertical movement of the connector.

[0012] The technological advancements achieved by this utility model are as follows, due to the adoption of the above technical solutions.

[0013] This utility model provides a floating crossbeam for a tension screen. The screen mesh is set between the screen walls by the crossbeam. When the crossbeam moves up and down, under the action of the guide rod, the crossbeam moves up and down in the floating groove, which drives the screen mesh to move up and down to screen the material on the screen mesh. This ensures the uniformity of the force on the screen mesh, avoids energy loss, and improves the screening efficiency. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] A type of tension screen uses a floating crossbeam, combined with Figs. 1 to 4 As shown, it includes a crossbeam 3 and a screen wall 1. Several crossbeams 3 are set to fix the screen. The crossbeams are long strip structures and are arranged along the width of the screen surface. The screen wall 1 is set at both ends of the crossbeam 3. A floating support assembly is set between the crossbeam 3 and the screen wall 1, so that the crossbeam 3 has the ability to float perpendicular to the screen direction.

[0021] The floating support assembly includes floating grooves 5 opened on the screen walls 1 on both sides of the crossbeam 3. Connectors 6 are provided in the floating grooves 5 for installing and fixing the crossbeam 3. Rubber springs 8 are provided on the upper and lower sides of the connectors 6 and the upper and lower end faces of the floating grooves 5 respectively to support the up and down movement of the connectors.

[0022] A guide rod 9 is provided inside the floating groove 5. The guide rod 9 is set perpendicular to the connector 6 and passes through the connector 6 to guide the vertical movement of the connector, ensuring that the connector can only move in the vertical direction.

[0023] Two mounting holes 10 are provided at each end of the crossbeam 3. The connector 6 has mounting holes corresponding to the mounting holes 10 on the crossbeam. The crossbeam 3 is fixed to the connector 6 by mounting bolts 7.

[0024] The screen 2 and the crossbeam 3 are connected by a quick-release buckle 4. The quick-release buckle 4 includes a connecting strap 14 that passes through the screen 2 and the crossbeam 3. The end of the connecting strap 14 is provided with a fixing frame 11. The two side walls of the fixing frame 11 are respectively provided with snap-fit ​​grooves. Several sets of snap-fit ​​ends 13 are provided on both sides of the connecting strap 14. The connecting strap extends into the connecting frame and is fixed by snapping into the snap-fit ​​grooves through the snap-fit ​​ends.

[0025] The snap-fit ​​end 13 has an inclined structure that gradually widens from the end of the connecting strip to the end of the fixed frame. The end of the snap-fit ​​end is suspended. When releasing the snap-fit, the connecting strip can be removed from the fixed frame by pushing the snap-fit ​​end inward at the snap-fit ​​groove, thus releasing the snap-fit ​​buckle.

[0026] A quick-release part 12 is provided on the fixing frame 11 on the outside of the snap-fit ​​groove. The quick-release part 12 is made of rubber and covers the snap-fit ​​groove. Pushing the snap-fit ​​part inward can disengage the snap-fit ​​end 13 from the snap-fit ​​groove. At the same time, it can also prevent the screened raw materials from entering the snap-fit ​​groove, causing blockage of the snap-fit ​​groove and making it inconvenient to operate the quick-release buckle.

[0027] In use, this invention features a tensioning screen where the crossbeam moves up and down within a floating trough under the guidance of a guide rod, causing the screen mesh to move up and down to screen the material. The crossbeam's movement of the entire screen mesh ensures uniform force distribution, avoids energy loss, and improves screening efficiency. To replace the crossbeam, remove the fixing bolts on both sides of the connector, then press the quick-release parts on both sides of the fixing frame on the snap-fit ​​interface inwards. Once the snap-fit ​​end releases its locking groove, the connecting strap can be removed from the fixing frame, allowing for crossbeam replacement. Screen replacement is also quick and easy, achieved solely through the quick-release parts.
