Description

Technical Field

[0001] This invention relates to the field of cement pre-processing equipment technology, and more specifically, to a cement pre-processing apparatus. Background Technology

[0002] Autoclaved aerated concrete (AAC) falls under the category of lightweight concrete and is characterized by its low density and excellent thermal insulation properties. During production, a special foaming agent or air-entraining agent is added according to a specific ratio, creating numerous fine pores within the concrete and significantly reducing its apparent density. The concrete block cutting process involves cutting the molded concrete into block-shaped products according to the design specifications.

[0003] Currently, metal cutting wires are typically used when cutting blocks. The blocks are cut by the reciprocating movement of the tensioned metal cutting wire. However, if the metal wire breaks during the cutting process, the broken metal wire will continue to move downwards, causing the metal wire to get caught in the interior of the block, resulting in the block breaking. In addition, the cut surface is roughened and has a fish-scale appearance, which reduces the processing quality.

[0004] In view of this, we propose a cement prefabrication processing device. Summary of the Invention

[0009] Furthermore, the cross plate is fixedly connected to a connecting frame, the pawl passes through the connecting frame and the two are slidably connected, the pawl is fixedly connected to a limiting plate, and a spring is fixedly connected between the limiting plate and the connecting frame.

[0010] Furthermore, the sliding frame is fixedly connected to two mounting plates, and a rotating shaft is rotatably connected between the two mounting plates. A connecting block is fixedly connected to the rotating shaft, and a torsion spring is fixedly connected between the connecting block and the mounting plate.

[0011] Furthermore, the connecting block is fixedly connected to a fixed shell, the fixed shell is slidably connected to a sliding column, a second spring is fixedly connected between the sliding column and the fixed shell, and the sliding column is rotatably connected to a guide wheel.

[0012] Furthermore, a fan-shaped groove is provided on one side of the connecting block, and a limiting block is fixedly connected to the mounting plate, with the limiting block located within the fan-shaped groove of the connecting block.

[0016] Beneficial effects Compared with the prior art, the present invention provides a cement prefabricated product processing device, which has the following beneficial effects: 1. When the cutting wire breaks during the cutting process, the spring force will drive the connecting block and guide wheel to rotate downwards. At the same time, the second spring pushes the guide wheel to slide, actively pushing the broken wire out of the block cut. Then the pawl and ratchet automatically separate, and the spring releases the elastic force to drive the winding wheel to rotate in the opposite direction, quickly winding up and pulling out the broken wire. This effectively avoids the wire from getting caught in the block, causing the block to break or the surface to become rough and fish-scale-like, thus improving the quality of the finished product.

[0017] 2. When a cutting wire breaks, its corresponding limiting mechanism automatically releases the lock on the winding wheel and completes winding. Meanwhile, the limiting mechanisms corresponding to the other intact cutting wires remain in normal working condition, the support frame continues to move downward, and the remaining wires can cut the blocks normally without interrupting the entire cutting process, thus ensuring the continuity of the cutting operation and the overall processing efficiency.

[0023] This invention provides a cement prefabrication processing device, such as... Figures 1-4 As shown, it includes: support platform 1, guide column 2, connecting frame 3, support base 4, support frame 5, sliding frame 6, linear motor 7, guide rail 8, sliding frame 9, support leg 10, fixed shaft 11, winding wheel 12, spring 13, cutting wire 14, electric push rod 15, support leg 2 16, connecting sleeve 17, limit mechanism and drive mechanism; A support platform 1 is provided, with four guide columns 2 fixedly connected to it.

A linear motor 7 is fixedly connected to the support frame 5, and the output shaft of the linear motor 7 is fixedly connected to the sliding frame 6. Multiple guide rails 8 are provided, each fixedly connected to both sides of the sliding frame 6. A sliding frame 9 is slidably connected inside the guide rail 8. A support leg 10 is fixedly connected to the sliding frame 9. The support leg 10 is rotatably connected to a fixed shaft 11. The fixed shaft 11 rotates... A winding wheel 12 is dynamically connected; a spring 13 is fixed between the winding wheel 12 and the fixed shaft 11, and a cutting wire 14 is fixed between the winding wheels 12 on both sides; a limiting mechanism is set on the sliding frame 9, and the limiting mechanism is used to limit the winding wheel 12; a driving mechanism is set between the support platform 1 and the connecting frame 3, and the driving mechanism is used to drive the support frame 5 to slide along the guide column 2; an electric push rod 15 is fixedly connected to the guide rail 8, and the telescopic end of the electric push rod 15 is fixedly connected to the sliding frame 9; a second support leg 16 is fixedly connected to the sliding frame 9, and the second support leg 16 is provided with a circular through hole, through which the fixed shaft 11 passes.

[0024] Place the block on the support base 4, then start the linear motors 7 on the front and rear sides. The output shafts of the two linear motors 7 drive the sliding frame 6 to slide down along the lower side of the support frame 5. Then control the drive mechanism to make the support frame 5 move down along the four guide columns 2. The sliding frame 6 drives the cutting wire 14 on it to move back and forth to cut the block.

[0025] When cutting the blocks, the electric push rod 15 is controlled to make the sliding frame 9 slide along the guide rail 8 to ensure the tension of the cutting wire 14. At the same time, the limiting mechanism limits the winding wheel 12, and the spring 13 is in a charged state.

[0026] like Figures 4-8 As shown, the limiting mechanism includes: ratchet 18, horizontal plate 19, pawl 20, connecting frame 21, limiting plate 22, spring 1 23, mounting plate 24, rotating shaft 25, connecting block 26, torsion spring 27, fixed shell 28, sliding column 29, spring 20, guide wheel 31, sector groove 32, limiting block 33, gear 34, vertical column 35, sliding plate 36, and rack 37; The connecting sleeve 17 is rotatably connected to the circular through hole of the second support leg 16. The fixed shaft 11 is located inside the connecting sleeve 17 and the two are rotatably connected. The ratchet 18 is fixedly connected to the connecting sleeve 17. The second support leg 16 is fixedly connected to a horizontal plate 19. The horizontal plate 19 is slidably connected to a pawl 20, which meshes with the ratchet 18. The horizontal plate 19 is fixedly connected to a connecting frame 21. The pawl 20 passes through the connecting frame 21 and the two are slidably connected. The pawl 20 is fixedly connected to a limit plate 22. A spring 23 is fixedly connected between the limit plate 22 and the connecting frame 21. The sliding frame 9 is fixedly connected to two mounting plates 24. A rotating shaft 25 is rotatably connected between the two mounting plates 24. A connecting block 26 is fixedly connected between the rotating shaft 25 and the mounting plate 24. A torsion spring 27 is fixedly connected to the connecting block 26; a fixed shell 28 is fixedly connected to the connecting block 26, a sliding column 29 is slidably connected to the fixed shell 28, a spring 30 is fixedly connected between the sliding column 29 and the fixed shell 28, and a guide wheel 31 is rotatably connected to the sliding column 29; a fan-shaped groove 32 is opened on one side of the connecting block 26, and a limit block 33 is fixedly connected to the mounting plate 24, the limit block 33 being located in the fan-shaped groove 32 of the connecting block 26; a gear 34 is fixedly connected to the rotating shaft 25, two vertical columns 35 are fixedly connected to the horizontal plate 19, a sliding plate 36 is slidably connected to the vertical columns 35, and a pawl 20 passes through the sliding plate 36; the top of the pawl 20 limits the sliding plate 36, and a rack 37 is fixedly connected to the sliding plate 36, the rack 37 meshing with the gear 34.

[0027] When installing the cutting wire 14, first rotate the fixed shell 28 and the connecting block 26 upwards, and the torsion spring 27 is tightened. The connecting block 26 drives the gear 34 to rotate through the rotating shaft 25. The gear 34 drives the rack 37 to move downwards. The rack 37 drives the sliding plate 36 to move downwards along the vertical column 35. The sliding plate 36 moves downwards, and then, under the elastic force of the spring 23, the pawl 20 moves downwards along the horizontal plate 19 and the connecting frame 21, so that the pawl 20 contacts the ratchet 18.

[0028] Then, the take-up wheel 12 is rotated, and the take-up wheel 12 drives the ratchet 18 to rotate circumferentially through the connecting sleeve 17. During the rotation of the ratchet 18, the pawl 20 limits the ratchet 18. Then, the spring 13 is tightened to store power. Then, the cutting wire 14 is installed and fixed on the take-up wheel 12 and wound around the lower side of the guide wheel 31. After the cutting wire 14 is fixed, the tension of the cutting wire 14 is controlled by the electric push rod 15. After the adjustment is completed, the fixing shell 28 is released. At this time, the supporting force of the cutting wire 14 on the guide wheel 31 is greater than the elastic force of the torsion spring 27. In the above process, the spring 23 is in a compressed state, and the sliding column 29 is located inside the fixing shell 28.

[0029] If the cutting wire 14 breaks during the cutting of the block, the elastic force of the torsion spring 27 is greater than the supporting force of the cutting wire 14 on the guide wheel 31. Under the action of the elastic force of the torsion spring 27, the connecting block 26 rotates along the mounting plate 24 through the rotating shaft 25. At the same time, under the action of the elastic force of the second spring 30, the sliding column 29 drives the guide wheel 31 to slide downward along the fixed shell 28. The guide wheel 31 pushes the broken cutting wire 14, thereby accelerating the removal of the broken cutting wire 14 from the cut of the block.

[0030] When the connecting block 26 rotates, the limiting block 33 limits the connecting block 26, causing the connecting block 26 and the fixed shell 28 to stop rotating at a specified angle. During the rotation of the connecting block 26 and the rotating shaft 25, the rotating shaft 25 drives the gear 34 to rotate, the gear 34 drives the rack 37 to move upward, the rack 37 drives the sliding plate 36 to move upward, the sliding plate 36 drives the pawl 20 to slide upward along the horizontal plate 19, the pawl 20 drives the limiting plate 22 to move upward, the spring 20 is compressed, and the pawl 20 separates from the ratchet 18. At this time, under the elastic force of the spring 13, the spring 13 drives the winding wheel 12 to rotate, and the winding wheel 12 winds up the broken cutting wire 14, so that the wire is pulled out from the cutting seam of the block, thereby preventing the broken cutting wire 14 from causing quality damage to the block.

[0031] During the above process, the use of other intact cutting wires 14 is not affected. The support frame 5 continues to move downward along the guide post 2, allowing the other intact cutting wires 14 to cut the blocks, thus improving the cutting efficiency. Then, according to the above operation, a new cutting wire 14 is replaced.

[0032] like Figure 1 and Figure 9 As shown, the drive mechanism includes: a support column 38, a sprocket 39, a chain 40, a geared motor 41, and a connector 42; Two support columns 38 are provided, which are fixedly connected between the support platform 1 and the connecting frame 3 respectively. Both the support frame 5 and the support platform 1 are equipped with sprockets 39, and a chain 40 is wound between the two sprockets 39 on the upper and lower sides. Two reduction motors 41 are provided, which are fixedly connected to both sides of the support platform 1 respectively. The two reduction motors 41 are of the same model. The output shaft of the reduction motor 41 is fixedly connected to the adjacent sprocket 39. The support column 38 is slidably connected to the connector 42, which is fixedly connected to the support frame 5 and the chain 40.

[0033] When in use, the geared motors 41 on both sides are started. The output shaft of the geared motors 41 drives the sprockets 39 to rotate. The two sprockets 39 on the upper and lower sides rotate through the chain 40. The chain 40 drives the connector 42 to slide along the support column 38. The connector 42 drives the support frame 5 to slide downward along the four guide columns, so that the cutting wire 14 moves downward to cut the block.

[0034] Working principle of the invention: First, place the block to be cut on the support base 4. When installing the cutting wire 14, the operator rotates the fixed shell 28 and the connecting block 26 upwards, causing the torsion spring 27 to tighten and store force. The connecting block 26 drives the gear 34 to rotate via the rotating shaft 25. The gear 34 drives the rack 37, which meshes with it, to move downwards. The rack 37 drives the sliding plate 36 to slide downwards along the vertical column 35. The descent of the sliding plate 36 releases the restriction on the pawl 20. Under the elastic force of the spring 23, the pawl 20 moves downwards along the horizontal plate 19 and the connecting frame 21 until it contacts the ratchet 18.

[0035] Subsequently, the operator rotates the take-up reel 12, which drives the ratchet 18 to rotate circumferentially through the connecting sleeve 17. Under the unidirectional limiting action of the pawl 20 on the ratchet 18, the spring 13 gradually tightens and stores power as the take-up reel 12 rotates. The two ends of the cutting wire 14 are fixed to the take-up reels 12 on both sides, and the wire is wound around the lower side of the guide wheel 31. After fixing, the sliding frame 9 is driven to slide along the guide rail 8 by controlling the electric push rod 15 to precisely adjust the tension of the cutting wire 14. After adjustment, the fixing shell 28 is released. At this time, the upward supporting force of the tensioned cutting wire 14 on the guide wheel 31 is greater than the elastic force of the torsion spring 27, keeping the guide wheel 31 assembly in the working position. During the above process, the spring 23 is in a compressed state, and the sliding column 29 is located inside the fixing shell 28.

[0036] The linear motors 7 on both sides are activated, and their output shafts drive the sliding frame 6 to slide downwards along the lower side of the support frame 5, thereby causing the cutting wire 14 to reciprocate. Simultaneously, the reduction motors 41 on both sides are activated to drive the sprockets 39 to rotate. The upper and lower sprockets 39 are driven by a chain 40, which, through the connector 42, drives the support frame 5 to move smoothly downwards along the four guide posts 2 and the support post 38. The reciprocating motion of the sliding frame 6 and the downward feeding motion of the support frame 5 combine to enable the tensioned cutting wire 14 to efficiently reciprocate and cut the block. During this process, the pawl 20 in the limiting mechanism is always engaged with the ratchet 18 to prevent the winding wheel 12 from reversing under the elastic force of the spring 13, ensuring that the cutting wire 14 maintains a constant tension.

[0037] If a cutting wire 14 breaks during the cutting process, the supporting force of that cutting wire 14 on the guide wheel 31 will instantly disappear or decrease sharply. At this time, the elastic force of the torsion spring 27 is greater than the force exerted by the cutting wire 14 on the guide wheel 31. Driven by the elastic force of the torsion spring 27, the connecting block 26 rotates downward along the mounting plate 24 via the rotating shaft 25. At the same time, under the elastic force of the second spring 30, the sliding column 29 drives the guide wheel 31 to slide downward along the fixed shell 28. The guide wheel 31 actively pushes the broken cutting wire 14 downward, accelerating its separation from the cut of the block.

[0038] During the rotation of the connecting block 26, the engagement of the sector groove 32 and the limiting block 33 causes the connecting block 26 and the fixed shell 28 to rotate to a specified angle and then stop. Simultaneously, the rotating shaft 25 drives the gear 34 to rotate, which in turn drives the rack 37 to move upwards. The rack 37 then drives the sliding plate 36 to slide upwards along the vertical column 35. As the sliding plate 36 rises, its end pushes the pawl 20 to slide upwards along the horizontal plate 19, compressing the spring 23 and causing the pawl 20 to separate from the ratchet 18. After the ratchet 18 loses its limiting position, the elastic force stored in the spring 13 is released instantaneously, driving the winding wheel 12 to rotate rapidly in the opposite direction, automatically winding up the broken cutting wire 14, thereby completely extracting the wire from the cutting seam of the block and preventing the broken wire from causing scratches or other quality damage to the block surface.

[0039] After the broken wire is automatically reeled in, the cutting wire 14 in that path becomes ineffective, but the other intact cutting wires 14 remain unaffected. The support frame 5 continues to move downwards along the guide post 2, and the remaining intact cutting wires 14 can still cut the blocks, ensuring the continuity and efficiency of the cutting operation. The operator only needs to replace the broken cutting wire 14 and repeat the above installation and tension adjustment steps to restore the device to normal operation.

[0040] In all the solutions mentioned above, for connections between two components, welding, bolt and nut connection, bolt or screw connection, or other known connection methods can be selected according to the actual situation. These will not be elaborated here. For all fixed connections mentioned above, welding is preferred. Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
