DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Combination Figure 1 and Figure 2As shown, an aerated concrete block cutting device described in an embodiment of the present invention includes a base 1, a support frame 2 is slidably connected to the top of the base 1, a limiting groove is provided in the base 1, two rotating rods 24 are rotatably connected to the inner cavity of the support frame 2, one end of the rotating rod 24 is connected to the output end of the servo motor, an inclined plate 3 is fixedly connected to the middle of the top of the base 1, a placement plate 4 is fixedly connected to the front end surface of the base 1 on the side opposite to the support frame 2, a central axis rod 5 is rotatably connected to the top of the placement plate 4, a hook 6 is fixedly connected to the outer surface of the central axis rod 5, a knife pin 7 is fixedly connected to the inner wall of the placement plate 4, a clamping assembly is installed at the bottom of the support frame 2, the clamping assembly is used to fix the blocks to be cut, reset assemblies are installed at both ends of the central axis rod 5, the reset assembly is used to reset, so as to facilitate the next block cutting, a cutting assembly is installed on the outer surface of the hook 6, and the cutting assembly is used to cut the blocks; when working, the device is applied to concrete blocks on the construction site to facilitate the cutting of the blocks Timely cutting is performed. In the process of cutting the blocks, although the current scheme can evenly coat the cutting wire with paraffin wax and then cut the blocks with hot water, the blocks have many holes inside, resulting in good water content and no drying structure to adjust them. In severe cases, the blocks may collapse or become loose during cutting. Using the embodiment of the present invention, the blocks are first placed on the upper surface of the support frame 2, and the rotating rod 24 is driven by the output end of the servo motor to rotate. The rotating rod 24 rotates and twists with the support frame 2. Under the action of the threaded fit, the clamping assembly slides along the upper surface of the base 1 toward the direction close to the central axis 5. When the support frame 2 is displaced and moves to the limiting groove of the base 1, the servo motor is temporarily stopped. After the blocks are slowly pushed into the base 1, the servo motor is started again, so that the support frame 2 gradually moves toward the position of the blocks. The support frame 2 moves to squeeze the blocks. Under the action of the squeezing force, the blocks are clamped and fixed, so that there is no shaking during cutting, so as to improve the cutting accuracy.

[0035] When cutting is required, the hook 6 is pressed downward by hand to move, and the hook 6 rotates to drive the cutting assembly to move, and the cutting assembly generates a rotating force. The cutting assembly rotates to squeeze the blade in the knife pin 7, and the blade of the knife pin 7 is driven downward, and cuts into the building block through the displacement of the blade to achieve the purpose of building block cutting. In this process, the rotation of the cutting assembly will squeeze out a small amount of liquid, and the liquid will indirectly drip on the blade position to promote the smoothness of the cutting of the blade during cutting. At the same time, the connection between the blade and the cutting assembly is an elastic connection. After cutting, it will return to its original position due to the elastic action. The force generated when returning to its original position offsets the force of people pulling the hook 6 to move, thereby reducing labor intensity.

[0036] After the cutting process, the hook 6 is pressed downward by hand, and the hook 6 drives the central axis 5 to rotate. After the central axis 5 is driven to rotate, the central axis 5 drives the reset component to move. The reset component is affected by the rotation of the central axis 5 and moves upward. However, it is gradually restricted by the placement plate 4 during the upward displacement and resets again, so that the reset component moves with the downward pressure of the hook 6, achieving the function of automatic reset when the displacement force is released;

[0037] Combination Figures 2 to 5 As shown, the clamping assembly includes a vertical bar 21 installed on the upper surface of the support frame 2, the two rotating rods 24 are transmission-connected with a belt 22 at one end away from the support frame 2, and the outer surface of the rotating rod 24 is rotatably connected with a placement seat 25, and the bottom of the support frame 2 is fixedly connected with a guide block 23 and a limit seat 26, and the limit seat 26 and the guide block 23 are both located at the two ends of the bottom of the support frame 2, and the bottom end of the limit seat 26 is fixedly connected with a hook body 27, and the inner wall of the hook body 27 is elastically connected with a plurality of cotton strips 28, and the bottom of the placement seat 25 is fixedly connected to the upper surface of the base 1, and the specification size of the guide block 23 is adapted to the slide rail provided on the upper surface of the base 1, and the limit seat 26 is located at one end close to the placement seat 25; the cotton strips 28 and the hook body 27 are both made of elastic materials, and the hook body 27 is connected to the bottom of the support frame 2 The hook body 27 is composed of an upper part and a lower part. The upper and lower parts of the hook body 27 can contact with the cotton strip 28 when folded; when working, before cutting the block, in order to improve the cutting accuracy, it needs to be reinforced. Using the embodiment of the present invention, the rotating rod 24 is powered on and rotates counterclockwise, and the rotating rod 24 rotates and twists with the internal thread of the support frame 2. The support frame 2 is displaced under the action of the thread, and the guide block 23 gradually moves along the slide rail on the upper surface of the base 1. The support frame 2 slides along the outer side of the rotating rod 24, and the support frame 2 is displaced to the position of the placement seat 25. The vertical strip 21 is used to limit the block. Finally, the distance between the support frame 2 and the placement seat 25 is shortened, so that the block is positioned inside the base 1. Compared with the prior art, the operation is simpler and the clamping effect is more solid.

[0038] In addition, the movement of the support frame 2 drives the limit seat 26 to move synchronously, and the displacement of the limit seat 26 drives the hook body 27 and the cotton strip 28 to move. The hook body 27 wipes the bottom surface of the limit groove of the base 1, and the hook body 27 rubs and cleans the bottom surface in time to reduce the moisture infiltration into the block due to moisture. The hook body 27 is in a "V" shape by default, and the bent position of the hook body 27 collects moisture or debris. The cotton strip 28 itself has multiple holes and grooves, and the cotton strip 28 absorbs moisture or debris, thereby reducing the impact on the cleanliness of the block surface, which is convenient for improving the cleanliness of the block.

[0039] When the tampon 28 needs to be replaced, power is turned on to pull the distance between the support frame 2 and the placement seat 25, and then the bottom of the hook body 27 is pulled out by hand, and the hook body 27 becomes straight. After the hook body 27 is straightened, the tampon 28 is removed, and a new tampon 28 is reinserted when it needs to be installed, so as to facilitate cleaning of the tampon 28 and the hook body 27.

[0040] Combination Figure 6 and Figure 7 As shown, the reset assembly includes pulleys 51 installed at both ends of the central axis rod 5, the bottom end of the pulley 51 is fixedly connected to a connecting plate 52, the internal transmission connection of the connecting plate 52 is connected to a through rod 53 at the bottom end of the connecting plate 52, and the end of the through rod 53 close to the hook 6 is connected to the placement plate 4, the placement plate 4 is provided with a slot, and the slot of the placement plate 4 is fixed with a spring 54; one end of the wire rope inside the connecting plate 52 is wound around the outside of the central axis rod 5, and the other end is wound around the outside of the through rod 53, and the spring 54 is connected to the through rod 53; during operation, the hook 6 squeezes the blade in the knife pin 7 downward, and the blade extends out to cut the block, and multiple cutting means multiple knife outs, so it is necessary to retract the knife multiple times to facilitate the next cutting. If it is used for a long time, the labor is large and it is easy to get tired. When using the embodiment of the present invention, the hook 6 The rotation drives the cutting assembly to move, and the movement of the cutting assembly drives the central axis rod 5 to move synchronously. The central axis rod 5 rotates and works inside the pulley 51. The central axis rod 5 rotates and wraps around the wire rope to move. The wire rope is gradually wound and tightened. The other end of the wire rope is wrapped around the outside of the through rod 53 by default. The through rod 53 moves upward with the tightening force of the wire rope, and the through rod 53 moves upward along the inner wall of the connecting plate 52. The through rod 53 displaces and squeezes the spring 1 54 to move. The spring 1 54 squeezes the placement plate 4 upward, and the spring 1 54 changes from an extended state to a compressed state. The spring 1 54 is compressed together. After the blade in the knife pin 7 has finished cutting, when the hook 6 releases the downward pressure, the wire rope changes back to a loose state, and the spring 1 54 gradually resets, thereby reducing the steps of manually pushing the hook 6 back to its original position. Through the cooperation of the pulley 51, the wire rope and the spring, the manual effort is reduced, which is convenient for better cutting.

[0041] Combination Figures 8 to 10As shown, the cutting assembly includes a roller 61 installed on the outside of the central axis 5, and the roller 61 is composed of a turntable and a protrusion. Push plates 60 are fixedly connected to the protrusions of the roller 61 on both sides, and a spring 2 66 is fixedly connected to the outside of the roller 61. The top of the spring 2 66 is elastically connected to a heat pipe 67, and the bottom of the heat pipe 67 is fixedly connected to a dredging pipe 69. A guide seat 62 is installed on the outside of the heat pipe 67. During operation, since the blocks are relatively dry, the friction between the inner wall of the blocks and the blade is large during cutting. After frequent cutting, the knife may not return to its original position or the cutting may not be smooth. If it is directly moistened with water and cut, it may collapse or break easily. When using the embodiment of the present invention, the hook 6 drives the roller 61 to rotate. When the roller 61 rotates, its own protrusion moves accordingly, and the push plate 60 moves synchronously with the roller 61. When the protrusion of the roller 61 rotates, it squeezes the knife pin 7 and the spring 2 66 to move, and the blade in the knife pin 7 cuts downward, and the spring 2 66 squeezes the heat pipe 67 to move. The inside of the heat pipe 67 is squeezed and a small amount of water drops out, and is transmitted to the knife pin 7 through the dredging pipe 69, so that the water droplets and the blade in the knife pin 7 are indirectly moisturized, thereby improving the cutting efficiency, reducing the situation of knife jamming, and avoiding directly adding water to the block to affect the overall cutting effect; it should be noted that the blade in the knife pin 7 is a toothless blade.

[0042] Combination Fig. 9 and Fig.10 As shown, a knife pin 7 is slidably connected to the bottom of the protruding part of the rotating roller 61, a through rod 63 is connected to the top of the guide seat 62, a vertical plate 64 is fixed to the bottom end of the through rod 63, and an elastic inclined strip 65 is fixed to the bottom end of the vertical plate 64, and a fixed frame 68 is connected to the inside of the guide seat 62, and the two ends of the fixed frame 68 are located between the inner side walls of the two placement plates 4. The spring 66 penetrates the inside of the fixed frame 68 and is connected to the through rod 63. The rotating roller 61 is located at the bottom of the hook 6, and the central axis rod 5 penetrates the rotating roller 61 and extends to the placement plate 4. Drying components are installed on both sides of the guide seat 62, and the drying components are used to wipe and clean the side of the block to be cut; when working, the blade of the knife pin 7 is cut due to the extrusion force of the hook 6. , that is, the blade and the hook 6 are in a separated state. After cutting, the blade of the knife pin 7 is easy to stop at the bottom instead of resetting upward. When the blade of the knife pin 7 is displaced downward, the blade of the knife pin 7 drives the elastic bevel 65 to move downward. The elastic bevel 65 is stretched longer and longer as the blade of the knife pin 7 is displaced. After the blade of the knife pin 7 completes the cutting, the force of the elastic bevel 65 is gradually retracted. The elastic bevel 65 itself is elastic. At the moment when the hook 6 is manually pressed down, the pressure is reduced, and the internal stress of the downward pressure is increased. Then, the return is completed through the hook 6. The fixed frame 68 and the guide seat 62 play a role in stabilizing the equipment. The role of the through rod 63 is to facilitate the fixing of the other end of the elastic bevel 65 to prevent loosening when one end is deformed.

[0043] Combination Fig.11 and Fig.12 As shown, both sides of the guide seat 62 are slidably connected with assembly plates 621, and the two assembly plates 621 are fixedly connected to the inner wall of the inclined plate 3. The bottom end of the assembly plate 621 is rotatably connected with a transfer bar 622, and the outer surface of the transfer bar 622 is fixedly connected with a clamping bar 1 623 and a clamping bar 2 626, and the outer side of the clamping bar 1 623 is fixedly connected with a long plate 624, and the bottom end of the long plate 624 is fixedly connected with a cone 625, and the bottom end of the cone 625 is rotatably connected with a fan blade 628, and a set 627 is fixedly connected between the two clamping bars 2 626; the set 627 is adapted to the length of the guide seat 62, and a torsion spring is installed inside the transfer bar 622; when working, When the block falls from the top of the support frame 2 into the limiting groove of the base 1, the block is prone to tilt, resulting in the situation of standing on the side of the limiting groove of the base 1. After tilting, it is easy to be clamped unsteadily, so the block needs to be supported, and the roller 61 rotates to drive the guide seat 62 to move. Before the blade of the knife pin 7 moves downward and does not reach the block, the guide seat 62 rotates outward with a large amplitude. When the guide seat 62 swings, it first contacts the set 627, and the set 627 flips over. The set 627 folds over and contacts the block, and the side of the block fits the concave position in the middle of the set 627, so that the block is adjusted from an inclined state to an upright state, achieving the function of automatic and rapid support;

[0044] During operation, since the blade of the knife pin 7 is treated with dripping water, frequent cutting can easily cause more moisture to appear inside the base 1, and more moisture affects the cutting quality of the block. Using the embodiment of the present invention, the kit 627 is stuck on the edge of the block, and the block is pushed downward into the base 1. When the kit 627 rotates, the kit 627 squeezes the second card strip 626, and the second card strip 626 and the first card strip 623 move synchronously. The transfer bar 622 is twisted, and the first card strip 623 is displaced to squeeze the long plate 624 to move. The long plate 624 drives the cone 625 to move synchronously. The cone 625 moves downward with the action of the flipping force, and the long plate 624 wipes the side of the block. When the cone 625 moves downward, it gradually drives the fan blade 628 to move. The fan blade 628 rotates under the influence of the movement force during the displacement. When the fan blade 628 rotates, the internal moisture is gradually fanned out upward, thereby accelerating the ventilation inside the base 1, reducing the internal moisture, and improving the practical effect of cutting.

[0045] Working principle: When working, before cutting the block, in order to improve the cutting accuracy, it is necessary to reinforce it. Using the embodiment of the present invention, the rotating rod 24 is powered on and rotates counterclockwise, and the rotating rod 24 rotates and twists with the internal thread of the support frame 2. The support frame 2 is displaced under the action of the thread, and the guide block 23 gradually moves along the slide rail on the upper surface of the base 1. The support frame 2 slides along the outer side of the rotating rod 24, and the support frame 2 is displaced to the position of the placement seat 25. The vertical bar 21 is used to limit the block. Finally, the distance between the support frame 2 and the placement seat 25 is shortened, so that the block is positioned inside the base 1. Compared with the prior art, the operation is simpler and the clamping effect is more solid.

[0046] In addition, the movement of the support frame 2 drives the limit seat 26 to move synchronously, and the displacement of the limit seat 26 drives the hook body 27 and the cotton strip 28 to move. The hook body 27 wipes the bottom surface of the limit groove of the base 1, and the hook body 27 rubs and cleans the bottom surface in time to reduce the moisture infiltration into the block due to moisture. The hook body 27 is in a "V" shape by default, and the bent position of the hook body 27 collects moisture or debris. The cotton strip 28 itself has multiple holes and grooves, and the cotton strip 28 absorbs moisture or debris, thereby reducing the impact on the cleanliness of the block surface, which is convenient for improving the cleanliness of the block.

[0047] Since the hook 6 squeezes the blade in the knife pin 7 downward, the blade extends out to cut the block, and multiple cutting means multiple knife extensions. In order to facilitate the next cutting, the knife needs to be retracted multiple times. Long-term use requires a lot of labor and is easy to get tired. Using the embodiment of the present invention, the hook 6 rotates to drive the cutting assembly to move, and the movement of the cutting assembly drives the central axis rod 5 to move synchronously. The central axis rod 5 rotates to work inside the pulley 51, and the central axis rod 5 rotates to wrap around the wire rope. The wire rope is gradually wound and tightened, and the other end of the wire rope is wrapped around the outside of the through rod 53 by default. The through rod 53 moves with the wire rope. The tightening force of the rope moves upward, and the through rod 53 moves upward along the inner wall of the connecting plate 52. The through rod 53 displaces and squeezes the spring 54 to move. The spring 54 squeezes the inside of the placement plate 4 upward, and the spring 54 changes from an extended state to a compressed state. The springs 54 are compressed together. After the blade in the knife pin 7 has finished cutting, when the hook 6 releases the downward pressure, the wire rope becomes loose again, and the spring 54 gradually returns to its original position, thereby reducing the steps of manually pushing the hook 6 back to its original position. Through the cooperation of the pulley 51, the wire rope and the spring, the manual effort is reduced, which facilitates better cutting.

[0048] Since the blocks are relatively dry, the friction between the inner wall of the blocks and the blade is large during cutting. After frequent cutting, the knife may not return to its original position or the cutting may not be smooth. If it is directly moistened with water and cut, it may collapse or break. Using the embodiment of the present invention, the hook 6 drives the roller 61 to rotate. When the roller 61 rotates, its own protrusion moves accordingly. The push plate 60 moves synchronously with the roller 61. When the protrusion of the roller 61 rotates, it squeezes the knife pin 7 and the spring 2 66 to move. The blade in the knife pin 7 cuts downward, and the spring 2 66 squeezes the heat pipe 67 to move. A small amount of water droplets are squeezed inside the heat pipe 67 and drip out. The water droplets are transmitted to the knife pin 7 through the dredging pipe 69, so that the water droplets and the blade in the knife pin 7 are indirectly moisturized, thereby improving the cutting efficiency, reducing the problem of the knife being stuck, and avoiding directly adding water to the block to affect the overall cutting effect. It should be noted that the blade in the knife pin 7 is a toothless blade.

[0049] The blade of the knife pin 7 performs the cutting process due to the squeezing force of the hook 6, that is, the blade and the hook 6 are in a separated state. After cutting, the blade of the knife pin 7 is easy to stop at the bottom instead of resetting upward. When the blade of the knife pin 7 moves downward, the blade of the knife pin 7 drives the elastic bevel 65 to move downward. The elastic bevel 65 moves with the displacement of the blade of the knife pin 7, and the elastic bevel 65 is stretched longer and longer. After the blade of the knife pin 7 completes the cutting, the force of the elastic bevel 65 is gradually retracted. The elastic bevel 65 itself is elastic. At the moment when the hook 6 is manually pressed down, the pressure is reduced, and the internal stress of the downward pressure is increased. Then, the return is completed through the hook 6. The fixed frame 68 and the guide seat 62 play a role in stabilizing the equipment. The role of the through rod 63 is to facilitate the fixing of the other end of the elastic bevel 65 to prevent loosening when one end is deformed.

[0050] When the building block falls from the top of the support frame 2 into the limiting groove of the base 1, the building block is prone to tilt, causing it to stand on the side of the limiting groove of the base 1. After tilting, it is easy to become unstable. Therefore, the building block needs to be supported, and the roller 61 rotates to drive the guide seat 62 to move. Before the blade of the knife pin 7 moves downward and does not reach the building block, the guide seat 62 rotates outward and swings with a large amplitude. When the guide seat 62 swings, it first contacts the kit 627, and the kit 627 flips over. The kit 627 folds over and contacts the building block, and the side of the building block fits with the recessed position in the middle of the kit 627, so that the building block is adjusted from an inclined state to an upright state, thereby achieving the function of automatic and rapid support.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
