Description

Technical Field

[0001] This invention relates to the field of vibrating screen replacement technology, specifically to a device and method for automatically replacing the screen of a ceramic vibrating screen. Background Technology

[0002] In building ceramics enterprises, the quality of the slurry is the foundation for ensuring product quality. Sieving removes impurities from the slurry, making it an essential process. In ceramic production, both ball milling and spray tower processes require vibrating screens to screen the slurry. However, due to high production volumes and frequent, prolonged use, the screens often become loose due to the impact of the slurry. This prevents the screens from completely filtering out impurities, affecting slurry quality. Furthermore, some vibrating screens may experience screen breakage due to various factors during use. Timely replacement of the screens is crucial to ensuring the quality of sieving the slurry.

[0003] Currently, screen replacement is mainly done manually by employees. The process involves manually disassembling the vibrating screen, removing the screen mesh, cutting a suitable mesh for replacement, and then reinstalling it for use. This process is cumbersome, time-consuming, labor-intensive, and inefficient, and the quality of screen installation cannot be guaranteed.

[0004] Therefore, existing technologies still need to be improved and developed. Summary of the Invention

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0067] In view of the shortcomings of the prior art, this embodiment provides a device and method for automatically changing the screen of a ceramic vibrating screen, as detailed below:

[0068] As attached Figure 1As shown, a device for automatically changing the screen of a ceramic vibrating screen includes a frame 1, a screen frame picking and placing assembly 2, a fixed base 3, two screen hoop disassembly and assembly 4, and a screen cloth assembly 5. The screen picking and placing assembly is located on the top of the frame 1 and can move along the top of the frame 1, as well as clamp the screen for movement and lifting. The fixed base 3 is located inside the frame 1 and at the bottom of the screen frame picking and placing assembly 2, so as to facilitate the screen frame picking and placing assembly 2 to move the screen frame 6 to the top of the fixed base 3. The top of the fixed base 3 is provided with a groove 31, which cooperates with the screen frame 6, that is, the screen frame 6 can be placed into the groove 31. Two screen hoops are also included. Both the disassembly and assembly component 4 and the screen laying component 5 are mounted on the frame 1. The two screen hoop disassembly and assembly components 4 are located on both sides of the fixed base 3. The screen hoop disassembly and assembly components 4 are used to disassemble the screen hoop 61 of the screen frame 6 and the old screen. The disassembled screen hoop 61 is located on the screen hoop disassembly and assembly component 4. The screen hoop 61 can be installed back onto the screen frame 6 by restarting the screen hoop disassembly and assembly component 4. The screen laying component 5 is used to lay the new screen on the surface of the fixed base 3 and cover the groove 31. Through the cooperation of the above components, the screen frame 6 can be quickly replaced without manual intervention. This not only improves the efficiency of screen replacement but also saves a lot of labor.

[0069] Specifically, the screen frame pick-and-place assembly 2 moves to the position of the screen frame 6, clamps the screen frame 6, and moves it to the top of the fixed base 3. Then, the screen hoop disassembly and assembly assembly 4 is activated. The screen hoop disassembly and assembly assembly 4 clamps the screen hoop 61 and the old screen and disassembles the screen hoop 61 and the old screen. The old screen is placed in the designated position by the screen hoop disassembly and assembly assembly 4. Then, the new screen is laid on the surface of the fixed base 3 by the screen mesh laying assembly 5, completely covering the groove 31. Then, the screen frame pick-and-place assembly 2 drives the screen frame 6 to descend until it falls into the groove 31. At this time, the screen frame 6 presses on the top of the screen and is squeezed into the groove 31, realizing the fit between the bottom of the screen frame 6 and the screen. Then, the screen hoop 61 is installed on the outer surface of the screen frame 6 using the screen hoop disassembly and assembly component 4, which also fixes the screen mesh. Finally, the screen frame 6 is moved to the working position using the screen frame pick-and-place component 2. By cooperating with the screen hoop disassembly and assembly component 4, the screen hoop 61 and the old screen mesh can be disassembled. The screen mesh laying component 5 can be used to lay the new screen mesh. By placing the screen frame 6 into the groove 31, the screen mesh is made to fit with the screen frame 6. The screen hoop 61 is then installed using the screen hoop disassembly and assembly component 4 to fix the new screen mesh. This effectively solves the problem of low efficiency in replacing vibrating screen mesh. Moreover, the replacement process does not require manual intervention and can be automatically replaced, saving a lot of manual labor.

[0070] The fixing seat 3 can also be set separately, that is, the fixing seat 3 is set on the ground by the support frame and located inside the frame 1, so as to facilitate the replacement of the fixing seat 3; at the same time, the fixing seat 3 also needs to be positioned to prevent the fixing seat 3 from shifting.

[0071] One embodiment of this application is shown in the appendix. Figure 2 and attached Figure 3 As shown, the screen frame loading and unloading assembly 2 includes a movable plate 21, a drive assembly, a first lead screw module 22, and a clamping cylinder 23. The frame 1 is composed of multiple profiles with an opening at the top. The movable plate 21 is slidably mounted on the top of the frame 1, and the drive assembly is mounted on the movable plate 21. The drive assembly cooperates with the movable plate 21 and the frame 1 to drive the movable plate 21 to slide on the frame 1. The first lead screw module 22 is mounted on one side of the movable plate 21, and the slider of the first lead screw module 22 is mounted on one side of the movable plate 21, that is, the body of the first lead screw module 22 can move up and down relative to the movable plate 21. The clamping cylinder 23 is mounted at the bottom of the first lead screw module 22, and clamping blocks are mounted at both ends of the clamping cylinder 23, which can be used to clamp the screen frame 6.

[0072] The moving plate 21 can be moved to the top of the screen frame 6 where the screen needs to be replaced by the drive assembly. Under the action of the first lead screw module 22, the two clamping blocks of the clamping cylinder 23 are moved to both sides of the screen frame 6. The clamping cylinder 23 can be activated to clamp the screen frame 6. Then, the screen frame 6 is driven to rise by the first lead screw module 22. With the help of the drive assembly, the screen frame 6 can be moved to the top of the fixed seat 3. Then, with the help of the other components, the screen can be replaced.

[0073] In this embodiment, as shown in the appendix Figure 2 As shown, both the first lead screw module 22 and the clamping cylinder 23 are existing technologies. The two grippers of the clamping cylinder 23 can move towards or away from each other to clamp the screen frame 6. Furthermore, the clamping cylinder 23 can also be two single-axis telescopic cylinders. The two single-axis telescopic cylinders are stacked on top of each other, and the extended ends of the two single-axis telescopic cylinders are set in opposite directions so that when the two telescopic cylinders are activated at the same time, the extended ends of the two telescopic cylinders simultaneously abut against the surface of the screen frame 6 and clamp the screen frame 6.

[0074] In this embodiment, as shown in the appendix Figure 3 As shown, a guide rail is provided on each side of the top of the frame 1, and sliders are provided at both ends of the movable plate 21. The two sliders of the movable plate 21 correspond to the two guide rails and cooperate with each other so that the movable plate 21 can slide on the top of the frame 1 without deviating.

[0075] In this embodiment, the clamping block can be a rubber block to increase the friction between the clamping fingers of the clamping cylinder 23 and the screen frame 6.

[0076] In this embodiment, as shown in the appendix Figure 2As shown, the drive assembly includes a drive motor 24, a reducer, and a drive rack 27. The drive motor 24 is located at the bottom of the moving plate 21, and the reducer is located at the bottom of the drive motor 24. A connecting hole is located at the center of the reducer, and a rotating rod 25 is located in the connecting hole. By starting the drive motor 24, the rotating rod 25 can be driven to rotate. A drive gear 26 is located at each end of the rotating rod 25, and a drive rack 27 is located on each side of the top of the frame 1. The drive gear 26 meshes with the drive rack 27. When the drive motor 24 is started, the drive motor 24 drives the rotating rod 25 to rotate, and the drive gear 26 of the rotating rod 25 rolls along the drive rack 27, so that the moving plate 21 moves along the length direction of the drive rack 27.

[0077] One embodiment of this application is shown in the appendix. Figure 4 and attached Figure 5 As shown, the screen hoop disassembly and assembly assembly 4 includes a second lead screw module 41, a fixing plate 42, two disassembly components 43, and a clamping component 44. The two second lead screw modules 41 are respectively located on both sides of the frame 1. The second lead screw module 41 is existing technology, and a fixing plate 42 is provided on the slider of the second lead screw module 41. The two ends of the fixing plate 42 are provided with disassembly components 43. The disassembly components 43 are used to disassemble and install the screen hoop 61 of the screen frame 6. The fixing plate 42 is also provided with a clamping component 44, which is located between the two disassembly components 43 and is used to clamp the old screen mesh to detach it from the bottom of the screen frame 6 to facilitate the subsequent laying of the new screen mesh.

[0078] In this embodiment, as shown in the appendix Figure 5 As shown, the disassembly assembly 43 includes a first linear reducer 431, a first rack 433, a first mounting plate 434, an electric wrench 435, and a first finger-clamping cylinder 436. The first linear reducer 431 is mounted on the fixed plate 42. The first linear reducer 431 is existing technology. A first disassembly motor 432 is mounted on the top of the first linear reducer 431. The first rack 433 is installed inside the first linear reducer 431. The first rack 433 cooperates with the first linear reducer 431. By starting the first disassembly motor 432, the first rack 433 can be driven to move. The first rack 433 is positioned near the end of the screen frame 6, with a first mounting plate 434. An electric wrench 435 and a first finger-clamping cylinder 436 are mounted on the first mounting plate 434. Both the electric wrench 435 and the first finger-clamping cylinder 436 are existing technologies, and they are arranged side-by-side. The electric wrench 435 engages with the fixing bolts on the screen hoop 61, while the first finger-clamping cylinder 436 is used to clamp the screen hoop 61. By using the electric wrench 435 to remove the fixing bolts and cooperating with the first finger-clamping cylinder 436, the screen hoop 61 can be removed.

[0079] Specifically, when the screen frame assembly 2 moves the screen frame 6 to the top of the fixed base 3, the two second lead screw modules 41 are activated, moving the electric wrench 435 and the first finger-clamping cylinder 436 to the position corresponding to the screen hoop 61. Then, by activating the first disassembly motor 432, the first disassembly motor 432 drives the first rack 433 to move closer to the screen hoop 61 until the electric wrench 435 is pressed against the surface of the fixing bolt, and the two fingers of the first finger-clamping cylinder 436 are located at the upper and lower positions of the screen hoop 61. At this time, the clamping assembly 44 clamps the screen mesh outside the screen frame 6, and the first finger-clamping cylinder 436 clamps the screen hoop 61. Then, the electric wrench 435 is activated, and simultaneously... The first disassembly motor 432 is also started, moving the first mounting plate 434 away from the screen frame 6. At this time, the fixing bolts slowly loosen and, under the action of the first clamping cylinder 436 and the screen hoop 61, disengage from the screen frame 6. Meanwhile, the fixing bolts will be held in the mounting hole of the screen hoop 61 by the electric wrench 435, so they will not fall off. Until the screen hoop 61 is completely detached from the screen frame 6, the first mounting plate 434 is restored to its original position under the action of the first disassembly motor 432. Then, the clamping assembly 44 continues to move away from the screen frame 6 until the old screen is detached from the screen frame 6 and reaches the designated storage point. The clamping assembly 44 then releases the old screen.

[0080] After the screen hoop 61 and the old screen are removed, the screen laying assembly 5 lays the new screen on the surface of the fixed base 3. The screen frame taking and putting assembly 2 puts the screen frame 6 into the groove 31 so that the screen frame 6 matches the new screen. Then the first disassembly motor 432 is started, which moves the screen hoop 61 toward the screen frame 6. Under the action of the electric wrench 435, the screen hoop 61 can be re-fixed on the screen frame 6 and the new screen is fixed.

[0081] Furthermore, a guide block is provided on one side of the first linear reducer 431, and a guide rod is slidably disposed inside the guide block, the guide rod being connected to the first mounting plate 434.

[0082] In this embodiment, as shown in the appendix Figure 5 As shown, the clamping assembly 44 includes a second linear reducer 441, a second rack 443, a second mounting plate 444, and a second finger-clamping cylinder 445. The second linear reducer 441 is mounted on the fixed plate 42, and a second disassembly motor 442 is mounted on the top of the second linear reducer 441. The second rack 443 is also mounted inside the second linear reducer 441. The second rack 443 cooperates with the second linear reducer 441 and can be driven to move towards or away from the screen frame 6 under the action of the second disassembly motor 442. The second mounting plate 444 is mounted on the side of the second rack 443 near the screen frame 6, and the second finger-clamping cylinder 445 is mounted on the surface of the second mounting plate 444. The second finger-clamping cylinder 445 is used to clamp the old screen.

[0083] The disassembly component 43 and the clamping component 44 move independently, but they cooperate with each other. The disassembly component 43 disassembles the screen hoop 61, and the clamping component 44 clamps the old screen and removes it from the screen frame 6. Furthermore, the initial position of the clamping component 44 is away from the screen frame 6. After the second clamping finger cylinder 445 clamps the old screen, under the action of the second disassembly motor 442, the second clamping finger cylinder 445 carries the old screen away from the screen frame 6 to ensure that the old screen is completely removed from the screen frame 6 and the fixed seat 3, and does not affect the arrangement of the new screen.

[0084] Furthermore, a guide block is provided on one side of the second linear reducer 441, and a guide rod is slidably disposed inside the guide block, the guide rod being connected to the second mounting plate 444.

[0085] One embodiment of this application is shown in the appendix. Figure 6 As shown, the screen assembly 5 includes a support 51, a winding roller 52, two third screw modules 53, two third finger-clamping cylinders 54, and a cutting assembly. The support 51 is formed by welding multiple profiles and is set on the frame 1. The winding roller 52 is rotatably mounted on the support 51, and a new screen is wound on the winding roller 52. A third screw module 53 is set on each side of the support 51. The two third screw modules 53 are located on both sides of the fixed seat 3 to avoid interference with the screen frame 6. The bottom of the slider of the two third screw modules 53 is equipped with a third finger-clamping cylinder 54, which is used to clamp the new screen. The support 51 is also equipped with a cutting assembly for cutting the new screen.

[0086] In this embodiment, the screen frame 6 moves above the fixed base 3 under the action of the screen picking and placing assembly, and the screen frame 6 is located above the bracket 51 to avoid the placement of the new screen. In the initial state, the two third-finger cylinders 54 are located on the side close to the winding roller 52, and the third-finger cylinders 54 hold one end of the new screen. After the screen hoop 61 of the screen frame 6 and the old screen are disassembled, the third screw module 53 drives the third-finger cylinders 54 to move away from the winding roller 52, pulling the new screen to the surface of the fixed base 3. At this time, it can be used to... First, cut one end of the new screen and place it on the surface of the fixing seat 3. Then, insert the fixing seat 3 into the groove 31 and complete the assembly of the screen hoop 61 and fix the new screen. Alternatively, after the new screen is arranged, it can be in a taut state. Then, insert the fixing seat 3 into the groove 31. At this time, the bottom surface of the fixing seat 3 fits tightly with the new screen. Then, install the screen hoop 61 through the disassembly component 43. Finally, cut the new screen through the cutting component to complete the replacement of the old screen of the screen frame 6.

[0087] In this embodiment, as shown in the appendix Figure 7As shown, a rotating bearing is provided at one end of the bracket 51, and a damping wheel assembly is provided at the other end. One end of the winding roller 52 is located in the rotating bearing, and the other end is located in the damping wheel assembly. The damping wheel assembly provides damping for the rotation of the winding roller 52, preventing the winding roller 52 from rotating arbitrarily, which would cause the new screen to not be laid flat on the surface of the fixed seat 3, or not be in a taut state, resulting in wrinkles in the fit with the screen frame 6.

[0088] Further details are attached. Figure 7 As shown, the damping wheel assembly includes two support frames and an adjusting plate. Each of the two support frames 51 has a first transverse moving groove, and two rollers are installed in the first moving groove. One side of the two support frames is connected by two adjusting plates, and the adjusting plates have a second vertical moving groove to adjust the two support frames vertically. Through the first moving groove in the support frame, the second moving groove in the adjusting plate, and the four rollers, the winding roller 52 can be clamped and the damping magnitude of the winding roller 52 can be adjusted. At the same time, the rollers can be in the roller state without restricting the rotation of the winding roller 52. In addition, the adjusting plate can be disassembled to facilitate the installation of new screen winding components.

[0089] In this embodiment, the cutting assembly includes a fourth lead screw module 55, which is disposed at the bottom of the support 51 and at the top of the winding roller 52. The fourth lead screw module 55 is arranged perpendicularly to the third lead screw module 53. A slicing blade 56 is provided on the slider of the fourth lead screw module 55 for slicing the new screen. The slicing blade 56 can also be scissors or other devices capable of cutting the new screen.
