Description

Technical Field

[0001] This utility model belongs to the technical field of material screening, and in particular relates to a tensioning and fixing mechanism for a tension screen. Background Technology

[0002] Tension screens are high-efficiency screening elements specifically designed for tension screening equipment. They are typically composed of a metal frame and an elastic screen surface (such as polyurethane or rubber). Their core working principle involves the reciprocating motion of the screen box causing tension deformation of the screen surface. This allows the screen to exhibit both high-frequency vibration and elastic deformation characteristics during screening, effectively preventing fine particles from clogging the screen and significantly improving the screening efficiency for wet and sticky materials. These screens offer advantages such as high tear resistance, wear resistance, and good elastic recovery, making them suitable for screening complex materials such as coal slime, slurry, and construction waste. They play a crucial role in mineral processing and solid waste treatment, significantly increasing screening capacity and reducing maintenance costs compared to traditional rigid screens.

[0003] Utility model publication CN220804376U discloses a tension screen fixing and pressing device, including a bracket for engaging the screen and a pressing strip located above the bracket to press the screen into the bracket. Several fastening components are provided through the bracket and the pressing strip to fix them together. This utility model's tension screen fixing and pressing device, through the engaging arrangement of the U-shaped bracket and the T-shaped pressing strip, allows adjacent screens to be engaged on the bracket, and the pressing strip located between the two screens further enhances the stability of the tension screen during operation, improving screening accuracy and efficiency.

[0004] However, this solution also has some drawbacks. The pressure strip and the bracket are fixed together with too many bolts. Although this method is relatively tight, it is cumbersome to install and disassemble the tension screen. Utility Model Content

[0005] The purpose of this utility model is to provide a tensioning and fixing mechanism for a tension screen. This utility model solves the problem of the cumbersome installation and disassembly caused by using multiple sets of bolts for fixing in related solutions through the setting of fixing components.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a tensioning and fixing mechanism for a tension screen, including a fixing component. The fixing component includes a first locking part and a second locking part that are adapted to each other. The first locking part is also provided with an adjustment component.

[0008] The bottom end of the first snap-fit ​​component is also fixed with a bottom shell, and a snap-fit ​​groove is provided on the bottom shell. The snap-fit ​​component is also provided in the snap-fit ​​groove. A limit rod is fixed to the center of one side of the snap-fit ​​component. The limit rod is movably connected to the side wall of the snap-fit ​​groove. A spring is also provided on the outer periphery of the limit rod. The two ends of the spring abut against the snap-fit ​​component and the inner side wall of the snap-fit ​​groove, respectively. The second snap-fit ​​component is also fixed with a snap-fit ​​component that matches the snap-fit ​​groove.

[0009] Furthermore, the associated snap-fit ​​groove, snap-fit ​​component one, limit rod, spring one, and snap-fit ​​component two are grouped together, and several groups are provided.

[0010] Furthermore, two snap-fit ​​components and associated limit rods and springs are provided in the same snap-fit ​​slot, and the corresponding two are mirror images of each other.

[0011] Furthermore, both the first and second snap-fit ​​connectors have curved contact surfaces.

[0012] Furthermore, the adjustment assembly includes a connecting plate, and there are two connecting plates. All the limit rods on the same side of the device are fixed to the same connecting plate at the end away from the first snap-fit ​​part. A knob is also rotatably connected to the center of the bottom end of the bottom shell, and a push-out plate is fixed to the center of the inner end of the knob.

[0013] Furthermore, the adjustment assembly also includes a spring rod fixed to the bottom end of the bottom shell, with the telescopic end of the spring rod extending through the bottom shell into the snap-fit ​​groove.

[0014] This utility model has the following beneficial effects:

[0015] 1. This utility model, through its fixed assembly, allows for the placement of the edge of the tension screen mesh into the inner cavity of the first locking component during use. Then, the second locking component is inserted into the inner cavity of the first locking component, and the first locking component is pressed down until the second locking component is inserted into the locking groove. This achieves the pressing and fixing of the tension screen mesh. During this process, the second locking component moves downwards, pressing down on the first locking components on both sides, causing them to move to the sides. Finally, once the second locking component is fully inserted into the locking groove, it springs back, completing the locking of the second locking component. This solves the problem of cumbersome installation and disassembly due to the use of multiple sets of bolts in related solutions.

[0016] 2. This utility model, through its adjustable components, allows for disassembly by rotating a knob to rotate a push-out plate, pushing out a connecting plate and causing the connecting plates on both sides to move outwards. Ultimately, this causes the first and second locking parts to separate. Under the action of a spring rod, the second locking part disengages, thus completing the disassembly of the tension screen. This solves the problem that the above-mentioned solutions, which have multiple sets of locking parts, are still not convenient enough for disassembly, further improving its practicality.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] Please see Figure 1-5 As shown, this utility model is a tension sieve screen clamping and fixing mechanism, including a fixing component 1. The fixing component 1 includes a matching locking part 11 and a locking part 12. The locking part 11 is also provided with an adjusting component 2. The fixing component 1 is used to clamp the tension sieve. The locking part 11 and the locking part 12 work together to clamp the tension sieve screen that needs to be clamped. The adjusting component 2 can facilitate the quick adjustment of the fixing component 1 that is clamping, so that the locking part 11 and the locking part 12 can be quickly separated, and finally the tension sieve screen can be quickly disassembled.

[0027] The bottom end of the first snap-fit ​​component 11 is also fixed with a bottom shell 13. The bottom shell 13 has a snap-fit ​​groove 14. The snap-fit ​​component 15 is also provided in the snap-fit ​​groove 14. A limit rod 16 is fixed at the center of one side of the snap-fit ​​component 15. The limit rod 16 is movably connected to the side wall of the snap-fit ​​groove 14. A spring 17 is also provided on the outer periphery of the limit rod 16. The two ends of the spring 17 abut against the snap-fit ​​component 15 and the inner side wall of the snap-fit ​​groove 14, respectively. The second snap-fit ​​component 12 is also fixed with a second snap-fit ​​component 18 that is adapted to the snap-fit ​​groove 14.

[0028] The locking groove 14 and the locking component 15 cooperate to limit and fix the locking component 18 set on the locking component 12. Ultimately, the locking component 11 and the locking component 12 clamp the tension screen. The limiting rod 16 keeps the locking component 15 in the locking groove 14. The spring 17 provides a force to keep the locking component 15 in a protruding state. Thus, during use, when the locking component 18 is locked in the locking groove 14, the spring 17 blocks the protruding part of the locking component 18 to prevent it from falling off, and finally fixes it stably.

[0029] Furthermore, the associated snap-fit ​​groove 14, snap-fit ​​part one 15, limit rod 16, spring one 17 and snap-fit ​​part two 18 are set as a group, and several groups are provided. Several groups of parts are provided for fixing snap-fit ​​part one 11 and snap-fit ​​part two 12, which can improve the stability of the fixation between the two, thereby improving the stability of the tension screen clamping.

[0030] Furthermore, two locking elements 18 and associated limiting rods 16 and springs 17 are provided in the same locking groove 14, and the corresponding two are mirror images of each other. The two locking elements 15 lock one locking element 18, and the two provide force in opposite directions to prevent the shaking generated by the vibrating screen during screening from causing the locking elements 15 to disengage from the locking elements 18, thus preventing the screen mesh of the vibrating screen from detaching.

[0031] Furthermore, both the first snap-fit ​​component 15 and the second snap-fit ​​component 18 have curved contact surfaces. The curved contact surfaces of both components allow the pressure provided by the second snap-fit ​​component 18 to press the first snap-fit ​​component 15 on both sides when they come into contact, causing it to move to both sides. Finally, the second snap-fit ​​component 18 fully enters the snap-fit ​​groove 14 and then springs back, greatly increasing the convenience of installation.

[0032] Furthermore, the adjustment assembly 2 includes a connecting plate 21, and there are two connecting plates 21. All the limiting rods 16 on the same side of the device are fixed to the same connecting plate 21 at the end away from the snap-fit ​​15. A knob 22 is also rotatably connected to the bottom center of the bottom shell 13, and a push-out plate 23 is fixed to the inner center of the knob 22.

[0033] The connecting plate 21 is mainly used to control the clamping status of all the first clamping parts 15 to the second clamping parts 18. Rotating the knob 22 will drive the push plate 23 to rotate, pushing the connecting plates 21 on both sides to move outward, so that all the first clamping parts 15 and the second clamping parts 18 are separated, and finally the first clamping parts 11 and the second clamping parts 12 are separated, thereby completing the disassembly of the tension screen.

[0034] Furthermore, the adjustment assembly 2 also includes a spring rod 24 fixed to the bottom end of the bottom shell 13. The telescopic end of the spring rod 24 extends through the bottom shell 13 and into the snap-fit ​​groove 14. The spring rod 24 provides a force when disassembling the snap-fit ​​part 12, causing it to pop out quickly and improving disassembly efficiency.

[0035] The specific working principle of this utility model is as follows: When using this device, place the edge of the tension screen mesh into the inner cavity of the locking part 11, then insert the locking part 2 12 into the inner cavity of the locking part 11, and then press the locking part 11 until the locking part 2 18 is inserted into the locking groove 14, thereby achieving the pressing and fixing of the tension screen mesh. During the process, the locking part 2 18 moves down, pressing the locking parts 15 on both sides, causing them to move to both sides. Finally, after the locking part 2 18 is completely inserted into the locking groove 14, it springs back, completing the locking of the locking part 2 18. When disassembling, simply turn the knob 22. The knob 22 drives the push plate 23 to rotate, pushing out the connecting plate 21 so that the connecting plates 21 on both sides move outward, finally causing the locking part 11 and the locking part 2 12 to separate. Under the action of the spring rod 24, the locking part 2 12 is disengaged, thereby completing the disassembly of the tension screen mesh, greatly improving its convenience.

[0036] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall be protected by the present utility model.
