Description

Technical Field

[0001] This invention relates to the field of screen manufacturing technology, and in particular to a metal woven wire screen and its stress detection equipment. Background Technology

[0002] Metal woven wire mesh screens are widely used in screening and filtration processes in industries such as mining, metallurgy, chemicals, and food. After the screen is woven, a certain amount of residual stress remains inside. This is mainly due to the pulling, bending deformation of the metal wires during the weaving process, as well as the uneven distribution of weaving tension. Excessive residual stress can lead to deformation of the screen during use, unstable mesh size, and even premature breakage and failure, directly affecting screening efficiency and service life.

[0003] Currently, the main method for detecting stress in metal screens is sampling, which involves taking samples from the finished screens and sending them to the laboratory for residual stress analysis using an X-ray diffractometer. However, this offline detection method is slow and cannot provide timely feedback on process problems; moreover, the sampled screens are directly damaged, resulting in waste of raw materials.

[0004] Therefore, this application proposes a metal woven wire mesh and its stress detection equipment for online stress detection without affecting continuous screen production. Summary of the Invention

[0005] The purpose of this invention is to solve the problems in the prior art by proposing a metal woven wire mesh and its stress detection device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A stress testing device for a metal woven wire mesh includes a testing protective box for protecting an X-ray stress testing head and a storage assembly for temporarily storing the mesh. The X-ray stress testing head is disposed inside the testing protective box. The storage assembly includes multiple first support rollers and two second support rollers. Both second support rollers are rotatably connected to the surface of a fixed box. The switch of a reversing valve is fixedly connected to a reversing rope, and the upper end of the reversing rope is fixedly connected to the surface of a lifting block.

[0007] In some embodiments, a plurality of the first support rollers are rotatably connected to the surface of the lifting block, and the lifting block is vertically slidably connected inside the fixed box via a square slide bar.

[0008] In some embodiments, the lifting block slides on the surface of a square guide rod via an airbag. The airbag is disposed inside the square guide rod, and a reversing valve is fixedly connected to the bottom of the square guide rod. The reversing valve is connected to the airbag, and multiple reversing valves are connected sequentially via hoses.

[0009] In some embodiments, the X-ray stress detection head moves at the top of the detection chamber via a first moving component and a second moving component, wherein there are two sets of the first moving component.

[0010] In some embodiments, the first moving component includes a guide rail fixedly connected to the top of the detection housing and a first slider sliding on the surface of the guide rail, wherein the guide rail is arc-shaped and has the same curvature as the support mesh.

[0011] In some embodiments, the multiple airbags are deflated sequentially by a reset assembly, the reset assembly including an air tube horizontally fixedly connected inside the fixed box and interfaces fixedly connected at intervals to the surface of the air tube, the multiple interfaces being respectively connected to the multiple airbags through multiple hoses.

[0012] In some embodiments, a closed tube is slidably connected inside the trachea, and the surface of the closed tube has multiple openings, the spacing between the multiple openings increases sequentially, and a first spring is respectively sleeved on the surface of the multiple square guide rods located below.

[0013] In some embodiments, the surface of the lifting block is provided with a pressure assembly for bending the reversing rope.

[0014] In some embodiments, a clamping assembly for holding the screen is fixed on the side of the detection protective box near the storage assembly. The clamping assembly includes an upper clamping plate and a lower clamping plate, both of which are slidably connected to the surfaces of two fixed plates. Both fixed plates are fixedly connected to one side of the detection protective box.

[0015] A metal woven wire mesh includes side strips fixedly connected to both sides of the mesh, the side strips wrapping around both sides of the mesh, and the surface of the side strips having multiple mounting holes.

[0016] Compared with the prior art, the present invention provides a metal woven wire mesh and its stress detection device, which has the following beneficial effects.

[0017] 1. This invention uses a storage device to temporarily store the produced screens, preventing them from becoming tangled and affecting their static state. By inflating the air bladder, the lifting block drives the first support roller to slide. The lifting block and the reversing rope pull the reversing valve to change the direction of airflow, sealing the already filled air bladder and allowing the high-pressure airflow to inflate the next air bladder, thus enabling multiple first support rollers to slide sequentially.

[0018] 2. In this invention, a support net is set up to support and shape the screen inside the detection chamber. The arc-shaped support net can support the screen into a controllable shape, thereby improving the detection accuracy. The first slider moves along the guide rail, and the arc-shaped guide rail can make the X-ray stress detection head move along the arc trajectory of the support net, so that the X-ray stress detection head always keeps the spacing between the X-ray stress detection head and the shaped screen, thereby improving the detection accuracy.

[0019] 3. In this invention, a negative pressure air source is connected to an air pipe for air extraction. The second electric push rod and connecting block drive the closed tube to slide, so that the opening near the detection protective box corresponds to the interface near the detection protective box, thus deflating the airbag near the detection protective box. By sliding the closed tube, the opening and interface are aligned in sequence, thereby releasing the gas in the airbag in sequence, achieving the effect of sequential reset, and avoiding the inability to collect a large number of screens in time due to the reset of all the first support rollers.

[0020] 4. In this invention, by setting up a pressurizing component, when the lifting block slides to the limit position, the reversing rope is in a taut state and the reversing valve is in a half-open state. Under the action of the torsion spring, the top hook is driven to quickly abut against the surface of the reversing rope, causing the reversing rope to bend again and providing secondary tension to the reversing rope, thereby enabling the reversing valve to fully open and close for reversing.

[0021] Other advantages, objectives and features of the invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be learned from practice of the invention.

[0043] 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. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0044] Reference Figure 1-20 A stress testing device for a metal woven wire mesh 6 includes a testing protective box 1 for protecting the X-ray stress testing head 3 and a storage component 4 for temporarily storing the mesh 6. The X-ray stress testing head 3 is set inside the testing protective box 1. The X-ray stress testing head 3 is existing technology and will not be described in detail. The testing protective box 1 has through slots on both sides for the mesh 6 to enter and exit. refer to Figure 2-4 The bottom of the detection housing 1 is provided with a support net 2 for controlling the shape of the screen 6. The support net 2 is fixedly connected to the top of the lifting frame 201. The lifting frame 201 is vertically slidably connected to the bottom of the detection housing 1. The lifting frame 201 is driven to lift by the first electric push rod 202. The support net 2 is an upwardly convex arc shape.

[0045] Understandably, after the production of screen 6, screen 6 enters the inspection chamber 1 through a channel, keeping the screen 6 stationary inside the inspection chamber 1 to facilitate stress detection by the X-ray stress detection head 3. Simultaneously, a storage device temporarily stores the produced screen 6 to prevent it from becoming tangled and affecting its stationary state. Since screen 6 is relatively soft and easily bent, the spacing between it and the X-ray stress detection head 3 may vary, affecting the detection results. Therefore, a support net 2 is provided to support and shape the screen 6 inside the inspection chamber 1. The arc-shaped support net 2 can support the screen 6 into a controllable shape, thereby improving detection accuracy. The first electric push rod 202 drives the lifting frame 201 and the support net 2 to rise and fall. When not performing detection, the support net 2 is lowered to prevent friction with the screen 6 from affecting its movement. When the screen 6 is being inspected, the support net 2 is raised to support and shape the screen 6.

[0046] For details, please refer to Figure 5-6 The X-ray stress detection head 3 moves within the top of the detection housing 1 via the first moving component 301 and the second moving component 302. The first moving component 301 consists of two sets, including a guide rail 3011 fixedly connected to the top of the detection housing 1 and a first slider 3012 sliding on the surface of the guide rail 3011. The guide rail 3011 is arc-shaped and has the same curvature as the support net 2. An arc-shaped rack 3013 is fixedly connected to the surface of the guide rail 3011. A first gear 3014 is provided on the top of the first slider 3012 via a drive motor, and the first gear 3014 meshes with the arc-shaped rack 3013. The second moving component 302 includes two first guide rods 3021 and a second slider 3022 slidably connected to the surface of the first guide rods 3021. The X-ray stress detection head 3 is fixedly connected to the bottom of the second slider 3022. The two ends of the two first guide rods 3021 are respectively fixedly connected to the opposite side of the two first sliders 3012. The second slider 3022 is driven to move by a threaded post 3023. The threaded post 3023 is rotatably connected to the side of the two first sliders 3012. One end of the threaded post 3023 is fixedly connected to a synchronous pulley 3024. The lower surface of one of the first sliders 3012 is fixedly connected to another synchronous pulley 3024 through a drive motor. The two synchronous pulleys 3024 are connected by a synchronous belt 3025.

[0047] Understandably, the first moving component 301 and the second moving component 302 drive the X-ray stress detection head 3 to move along the X-axis and Y-axis, performing comprehensive stress detection on the screen 6 inside the detection housing 1. The drive motor drives the first gear 3014 to rotate, and with the cooperation of the first gear 3014 and the arc-shaped rack 3013, the first slider 3012 moves along the guide rail 3011. The arc-shaped guide rail 3011 allows the X-ray stress detection head 3 to move along the arc-shaped trajectory of the support net 2, ensuring that the X-ray stress detection head 3 always maintains the same distance from the shaped screen 6, thus improving detection accuracy. The drive motor drives the synchronous pulley 3024 to rotate, and with the cooperation of the synchronous belt 3025 and the synchronous pulley 3024, the threaded column 3023 rotates, thereby causing the second slider 3022 to move the X-ray stress detection head 3.

[0048] For details, please refer to Figure 3-4 7-8, The storage component 4 is located in front of the detection protective box 1. The storage component 4 includes multiple first support rollers 401 and two second support rollers 402. The first support rollers 401 and the second support rollers 402 are both disposed on the surface of the fixed box 403. The two second support rollers 402 are rotatably connected to the surface of the fixed box 403, and the two second support rollers 402 are respectively located on both sides of the fixed box 403. The multiple first support rollers 401 are rotatably connected to the surface of the lifting block 405. The lifting block 405 is vertically slidably connected to the surface of the square guide rod. The square guide rod is fixedly connected inside the fixed box 403.

[0049] Understandably, since the screen 6 needs to be kept stationary during stress testing, a storage component 4 is set up to wind and store the screen 6 produced during the testing process in order not to affect production efficiency. This does not affect production and keeps the screen 6 stationary inside the testing chamber 1. In the normal state, multiple first support rollers 401 are close to each other, and the screen 6 moves in a straight line between the multiple first support rollers 401 and the second support roller 402 and enters the testing chamber 1. When testing is performed, the lifting block 405 slides vertically on the surface of the square guide rod 404, causing the multiple first support rollers 401 to gradually separate. The screen 6 is wound in an S-shape around the surface of the multiple first support rollers 401, increasing the travel of the screen 6 and thus temporarily storing it. After the test is completed, the multiple first support rollers 401 are reset, allowing the winding roller to store the produced screen 6 at a faster winding speed, achieving online sampling inspection.

[0050] For details, please refer to Figure 8-11The lifting block 405 slides on the surface of the square guide rod 404 via the airbag 5. The airbag 5 is located inside the square guide rod 404. The upper end of the airbag 5 is fixedly connected to the lower surface of the lifting block 405. A reversing valve 501 is fixedly connected to the bottom of the square guide rod 404. The reversing valve 501 is connected to the airbag 5. Multiple reversing valves 501 are connected in sequence through hoses. One of the reversing valves 501 is connected to a high-pressure air source. The switch of the reversing valve 501 is fixedly connected to the reversing rope 502, and the upper end of the reversing rope 502 is fixedly connected to the surface of the lifting block 405.

[0051] Understandably, by inflating the airbag 5, the inflated airbag 5 pushes the lifting block 405 to slide, thereby causing the screen 6 to bend and wind. As the screen 6 gradually extends during production, the storage of the screen 6 requires multiple first support rollers 401 to slide and wind sequentially to avoid excessive tension on the screen 6 caused by synchronous sliding, which could lead to deformation of the screen 6. When storing the screen 6, the first support roller 401 closest to the detection housing 1 is first slid to begin the storage of the screen 6, by inflating the airbag 5... The air causes the lifting block 405 to slide the first support roller 401 away from the reversing valve 501. When the lifting block 405 and the first support roller 401 slide into place, the lifting block 405 pulls the reversing rope 502, which in turn pulls the reversing valve 501 to change the direction of airflow, sealing the already filled airbag 5, and allowing the high-pressure airflow to pass through the next reversing valve 501 to inflate the next airbag 5, thereby enabling the multiple first support rollers 401 to slide in sequence.

[0052] For details, please refer to Figure 8 , 12 -15, multiple airbags 5 are deflated sequentially through the reset assembly 7, causing multiple first support rollers 401 to reset sequentially. The reset assembly 7 includes an air pipe 701 that is horizontally fixedly connected inside the fixed box 403 and an interface 702 that is fixedly connected at intervals to the surface of the air pipe 701. Multiple interfaces 702 are respectively connected to multiple airbags 5 through multiple hoses. A closed tube 703 is slidably connected inside the air pipe 701. One end of the closed tube 703 is an open structure. Multiple openings 704 are opened on the surface of the closed tube 703. The spacing between the multiple openings 704 increases sequentially. Multiple sets of sealing rings 7041 are provided on the surface of the closed tube 703. The multiple sets of sealing rings 7041 correspond to the multiple openings 704 respectively. A connecting block 7031 is fixedly connected to one end of the closed tube. The connecting block 7031 is slidably connected to the surface of the trachea 701. A second electric push rod 7032 is fixedly connected to the surface of the connecting block 7031. The second electric push rod 7032 is fixedly connected to the inside of the fixed box 403. Multiple square guide rods 404 located below are respectively fitted with first springs 4041, which are used to push the lifting block 405 to reset.

[0053] Under normal conditions, the openings 704 on the surface of the sealed tube 703 are misaligned with the interface 702 to seal the interface 702, facilitating the inflation of the airbag 5. After the testing is completed, multiple first support rollers 401 need to be reset sequentially from the direction closest to the testing housing 1. During the reset, the negative pressure air source is connected to the air pipe 701 to evacuate air. First, the second electric push rod 7032 and the connecting block 7031 drive the sealed tube 703 to slide, so that the openings 704 near the testing housing 1 correspond to the interfaces 702 near the testing housing 1, thus deflating the airbag 5 near the testing housing 1. By sliding the sealed tube 703, the openings 704 are sequentially aligned with the interfaces 702, thereby releasing the gas in the airbag 5 sequentially. The upper lifting block 405 slides downwards to reset under gravity, and the lower lifting block 405 slides upwards to reset under the action of the first spring 4041. This achieves the effect of sequential reset, avoiding the inability to collect a large number of screens 6 in time due to the reset of all first support rollers 401.

[0054] For details, please refer to Figure 16-17 The surface of the lifting block 405 is provided with a pressure assembly 8 for bending the reversing rope 502. The pressure assembly 8 includes a top hook 801 rotatably connected to the surface of the lifting block 405. The top hook 801 corresponds to the reversing rope 502. A torsion spring is sleeved on the rotating shaft surface of the top hook 801 to drive the top hook 801 to abut against the reversing rope 502. The top hook 801 is temporarily separated from the reversing rope 502 through a rack and an incomplete gear 803. The incomplete gear 803 is fixedly connected to one end of the rotating shaft of the top hook 801. The rack is vertically slidably connected to the surface of the lifting block 405. The rack slides upward through a second spring 804 and meshes with the incomplete gear 803.

[0055] It is understandable that when the lifting block 405 drives the reversing rope 502 to pull the reversing valve 501, the reversing valve 501 will initially be in a half-open state, causing airflow to enter the next airbag 5 prematurely. When the pressure is insufficient, the airbag 5 cannot push the lifting block 405 to the top, thus preventing the reversing rope 502 from fully reversing the reversing valve 501. Therefore, to ensure the reversing rope 502 fully opens and closes the reversing valve 501, a pressurizing component 8 is installed. Under normal conditions, the torsion spring drives the top hook 801 to push the reversing rope 502 to bend. When the lifting block 405 slides away from the reversing valve 501... When in position 01, the second rack 802 abuts against the inner wall of the fixed box 403, causing the second rack 802 to push the incomplete gear 803 and the top hook 801 to rotate, temporarily separating from the reversing rope 502. When the lifting block 405 slides to the limit position, the reversing rope 502 is in a taut state, and the reversing valve 501 is in a half-open state. After the incomplete gear 803 and the rack are misaligned, under the action of the torsion spring, the top hook 801 is driven to quickly abut against the surface of the reversing rope 502, causing the reversing rope 502 to bend again, providing secondary tension to the reversing rope 502, thereby enabling the reversing valve 501 to fully open and close for reversing.

[0056] For details, please refer to Figure 4 and Figure 18 A clamping assembly 9 for holding the screen 6 is fixed on the side of the detection housing 1 near the storage assembly 4. The clamping assembly 9 includes an upper clamping plate 902 and a lower clamping plate 901. The upper clamping plate 902 and the lower clamping plate 901 are slidably connected to the surfaces of two fixed plates 903. The two fixed plates 903 are fixedly connected to one side of the detection housing 1. A third rack 904 is fixedly connected to both ends of the upper clamping plate 902 and the lower clamping plate 901. A second gear 905 is rotatably connected to the surface of the fixed plate 903. The two third racks 904 mesh with the second gear 905. The upper clamping plate 902 is driven to slide by a third electric push rod 906. The third electric push rod 906 is fixedly connected to one side of the detection housing 1.

[0057] Understandably, to prevent the screen 6 from moving or shaking due to the pulling force generated by the housing component 4 during the testing process, a clamping component 9 is set up to fix and clamp the screen 6, thus preventing the screen 6 from shaking during the testing process. During operation, the third electric push rod 906 drives the upper clamping plate 902 to slide downward. Under the action of the third rack 904 and the second gear 905, the lower clamping plate 901 moves synchronously with the upper clamping plate 902 to clamp the screen 6.

[0058] A type of woven metal wire mesh 6, reference Figures 19-20 It includes side strips 601 that are fixedly connected to both sides of the screen 6. The side strips 601 wrap around both sides of the screen 6, and multiple mounting holes 602 are provided on the surface of the side strips 601.

[0059] Understandably, during long-term use, the edges of the metal woven screen 6 are more prone to unraveling and fraying due to external pulling and friction. The side strips 601 wrap and fix the sides of the screen 6, which can improve the structural stability of the sides of the screen 6 and extend the overall service life of the screen 6. At the same time, the mounting holes 602 reserved on the surface of the side strips 601 can also facilitate clamping with the fixing structure during stress testing, and facilitate the subsequent installation of the screen 6 into the equipment in use.

[0060] In this invention, during the random inspection of the screen 6, firstly, the third electric push rod 906 drives the upper clamping plate 902 to slide downwards. Under the action of the third rack 904 and the second gear 905, the lower clamping plate 901 moves synchronously with the upper clamping plate 902 to clamp the screen 6. The first electric push rod 202 drives the lifting frame 201 and the support net 2 to rise, supporting and shaping the screen 6 inside the inspection housing 1. The first moving component 301 and the second moving component 302 drive the X-ray stress detection head 3 to move along the X-axis and Y-axis. With the cooperation of the first gear 3014 and the arc-shaped rack 3013, the first slider 3... 012 moves along guide rail 3011. The arc-shaped guide rail 3011 allows the X-ray stress detection head 3 to move along the arc-shaped trajectory of the support mesh 2, ensuring that the X-ray stress detection head 3 always maintains the same distance from the shaped screen mesh 6, thus improving detection accuracy. During the detection process, the production equipment continuously weaves the screen mesh 6, which is temporarily stored by the storage component 4. By inflating the airbag 5, the lifting block 405 drives the first support roller 401 to slide away from the reversing valve 501. When the lifting block 405 slides into position with the first support roller 401, the lifting block 405 pulls the reversing rope 502, thus reversing the direction. Rope 502 pulls the reversing valve 501 to change the airflow direction, sealing the already filled airbag 5, allowing high-pressure airflow to inflate the next airbag 5 through the next reversing valve 501, thus enabling the multiple first support rollers 401 to slide sequentially; the screen 6 is wound along the surface of the multiple first support rollers 401 in an S-shape, increasing the travel of the screen 6, thereby temporarily storing the screen 6. After the test is completed, the clamping assembly 9 releases the clamp on the screen 6, the support net 2 descends, and the winding roller on the rear side of the test housing 1 winds up the screen. At this time, the negative pressure air source is connected to the air pipe 701 to evacuate air, first through the second... The electric push rod 7032 and the connecting block 7031 drive the sealing tube 703 to slide, so that the opening 704 near the detection housing 1 corresponds to the interface 702 near the detection housing 1, thus deflating the airbag 5 near the detection housing 1. By sliding the sealing tube 703, the opening 704 is aligned with the interface 702 in sequence, thereby releasing the gas in the airbag 5 in sequence. The upper lifting block 405 slides down to reset under the action of gravity, and the lower lifting block 405 slides up to reset under the action of the first spring 4041. This achieves the effect of sequential reset, avoiding the situation where a large number of screens 6 cannot be collected in time due to the reset of all the first support rollers 401.
