Description

Technical Field

[0001] This invention relates to the field of concrete billet cutting technology, specifically to a cutting unit for autoclaved aerated concrete billets. Background Technology

[0002] Autoclaved aerated concrete (AAC) blocks and ALC wall panels, as lightweight and environmentally friendly new wall materials, have been widely used in the production of prefabricated buildings, residential buildings, and industrial plant enclosure structures. In a complete production line, after the blanks are demolded, they need to be longitudinally cut by a gantry-type longitudinal cutter using steel wire to divide the large-sized blanks into semi-finished products that meet national standards. The quality of the cutting and shaping directly determines the pass rate of the finished products after autoclaving. The steel wire cutting unit is the core functional component of the entire cutting production line.

[0003] Existing traditional aerated concrete longitudinal cutting machines mainly adopt an equidistant fixed wire hanging seat structure, which is not convenient for adjusting the wire spacing. This causes many inconveniences during the production of blocks of different specifications. At the same time, when changing the block width and reducing the wire spacing to produce thin plates, if the swing amplitude remains unchanged, the swing strokes of adjacent cutting wires will interfere with each other and collide, which can easily lead to wire entanglement and breakage.

[0004] To address the aforementioned issues, innovative designs are urgently needed based on existing approaches. Summary of the Invention

[0005] The purpose of this invention is to provide a cutting unit for autoclaved aerated concrete (AAC) billets to solve the problems mentioned in the background. The technical solution of this invention addresses the problem that existing technical solutions are too simplistic and provides a solution that is significantly different from existing technologies.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a cutting unit for autoclaved aerated concrete (AAC) billets, comprising a conveying base, vertically moving modules installed at the four corners of the conveying base, mounting frames mounted on the surfaces of both ends of the moving modules, a housing shell fixedly connected to the top of the mounting frames, concrete billets placed in the conveying area at the top of the conveying base, a vibrating cutting mechanism installed in the lower cavity of the housing shell, and a spacing adjustment mechanism installed in the upper cavity of the housing shell;

[0007] The vibrating cutting mechanism includes an offset rod that slides laterally on the inner wall of the housing. A wire hanging seat is sleeved on the surface of the offset rod. A wire hanging wheel is rotatably connected to the bottom of the wire hanging seat. A through groove is opened at the bottom of the housing. A first limiting rod is fixedly connected to the inner wall of the through groove. A guide wheel is sleeved on the surface of the first limiting rod corresponding to the position of the wire hanging wheel.

[0008] The guide wheel is rotatably connected to both sides of a synchronizing rod. The other end of the synchronizing rod is limited and slidable within the protrusion on the side of the wire hanging seat. A steel wire is fixedly connected to the wire hanging wheel. The steel wire passes through the guide wheel and is connected to another set of wire hanging wheels in the housing. The offset rod is equipped with a shaking component at both ends.

[0009] Preferably, the shaking assembly includes a first bushing sleeved at both ends of the offset rod, a connecting rod fixedly connected to the back end of the first bushing, a sliding plate fixedly connected to the end of the connecting rod away from the wire holder, a first spring fixedly connected to the back end of the sliding plate, the other end of the first spring fixedly connected to the inner wall of the receiving shell, an abutment rod fixedly connected between the connecting rods, a sliding block vertically limited and slidable below the connecting rod on the inner wall of the receiving shell, a driving rod rotatably connected to the end of the sliding block away from the inner wall of the receiving shell, and an abutment block fixedly connected to the middle surface of the driving rod.

[0010] Preferably, the spacing adjustment mechanism includes a sliding groove formed on the bottom surface of the upper cavity of the housing, a plurality of adjusting rods are slidably limited inside the sliding groove, the plurality of adjusting rods are arranged in a "V" shape and are hinged to each other at their ends, a linkage rod is slidably limited at the rear end of the adjusting rod at the upper limit of the inner wall of the housing, and an offset plate is slidably limited at the front end of the adjusting rod at the upper limit of the inner wall of the housing;

[0011] The adjusting rod consists of two sets of hinged rods. The ends of the two sets of hinged rods that are close to each other are hinged together and rotatably connected on the surface of the linkage rod. The ends of the two sets of hinged rods that are close to each other and far apart slide in the groove opened on the surface of the offset plate. The top of the middle part of the hinged rod is rotatably connected to a guide rod. The top of the wire hanging seat extends into the upper cavity of the housing and is fixedly connected to a fixing block. The end of the guide rod that is far away from the hinged rod slides within the fixing block. Adjusting components are provided at both ends of the top cavity of the wire hanging seat.

[0012] Preferably, the adjusting assembly includes a first oil tank fixedly connected to both ends of the top chamber of the wire hanger, a first piston rod slidingly within the first oil tank, the output end of the first piston rod being connected to the side end of the offset plate, and a second oil tank fixedly connected to the bottom chamber of the wire hanger below the sliding block, a second piston rod slidingly within the second oil tank, the output end of the second piston rod being fixedly connected to the bottom of the sliding block.

[0013] Preferably, a second limiting rod is laterally slidable on the inner wall of the accommodating shell. The second limiting rod passes through the middle of the hanging wheel. A guide groove is formed on the surface of the second limiting rod. A guide rod is fixedly connected to the inner wall of the hanging wheel corresponding to the guide groove. The guide groove is located on the surface of the second limiting rod and is formed in a spiral structure. The second limiting rod is located in the guide groove and is limited to slide within it.

[0014] Preferably, the wire-hanging seats are arranged in several groups evenly in the transverse direction on the surface of the offset rod, and the synchronizing rod is arranged in an "L" shape.

[0015] Preferably, the abutting block is arranged in a cam shape, and the driving rod is driven by a driving motor mounted on the sliding block. When the two sets of abutting blocks in the accommodating shell rotate, they alternately abut the abutting rod.

[0016] Preferably, the oil chamber of the first oil tank away from the offset plate is connected to the oil chamber at the top of the second oil tank via an oil delivery hose, and the linkage rod is driven by an electric push rod installed in the hanging wire seat.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. This invention includes an adjusting rod, a linkage rod, an offset plate, a guide rod, and a fixing block. An electric push rod drives the linkage rod to slide horizontally, which in turn causes multiple sets of "V"-shaped adjusting rods, hinged end-to-end, to expand or contract synchronously. The hinged joints of the adjusting rods pull the guide rods to move laterally, which in turn causes the fixing block to move. The fixing block then pulls all the wire-hanging seats to move synchronously along the surface of the offset rod. All the wire-hanging seats simultaneously complete equidistant displacement, allowing for a one-time, unified adjustment of the spacing between the entire row of steel wires. This eliminates the need for operators to individually disassemble and lock each wire-hanging seat, enabling rapid switching of block width specifications.

[0019] 2. This invention includes an offset rod, a wire hanging seat, a wire hanging wheel, a first limiting rod, a guide wheel, a synchronizing rod, a steel wire, and an adjusting assembly. During the process of the "V"-shaped adjusting rod retracting and extending to change the steel wire spacing, it simultaneously pushes the offset plate, squeezing the oil inside the first oil tank. The oil flows into the second oil tank through the oil delivery hose, driving the second piston rod to vertically raise and lower the sliding block as a whole. This changes the height position of the cam-shaped contact block at the end of the sliding block, thereby changing the stroke of the cam-shaped contact block pushing the contact rod, and thus changing the swing amplitude of the steel wire. This achieves automatic matching between spacing adjustment and swing amplitude. In the case of small spacing, a reduced swing amplitude can prevent adjacent steel wires from colliding and tangling. In the case of large spacing, an increased swing amplitude can fully peel off the slurry from the billet, preventing chipping and delamination of the blocks caused by cutting and squeezing.

[0020] 3. This invention is equipped with a second limiting rod, a guide groove, a guide rod, and a wire hanging wheel. When the wire spacing is changed by the wire hanging seat with the "V"-shaped adjusting rod, the wire hanging wheel slides laterally relative to the second limiting rod. The spiral guide groove forces the wire hanging wheel to rotate synchronously. During the rotation of the wire hanging wheel, the overall winding length of the wire is automatically changed. When the wire spacing is increased, the rotation angle of the wire hanging wheel is large, which stretches the wire and automatically increases the wire tension, preventing large-span wires from sagging due to cutting resistance and preventing wavy and uneven textures on the cut surface. When the wire spacing is reduced, the rotation angle of the wire hanging wheel is small, which reduces the tension of the wire and prevents stress concentration due to excessive tension during the production of ultra-thin sheets.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figures 1-8The present invention provides a technical solution: a cutting unit for autoclaved aerated concrete (AAC) billets, including a conveyor seat 1, vertical moving modules 2 installed at the four corners of the conveyor seat 1, mounting frames 3 installed on the surfaces of both ends of the moving modules 2, a housing shell 4 fixedly connected to the top of the mounting frame 3, concrete billets 5 placed in the conveying area at the top of the conveyor seat 1, a vibrating cutting mechanism installed in the lower cavity of the housing shell 4, and a spacing adjustment mechanism installed in the upper cavity of the housing shell 4;

[0032] The vibrating cutting mechanism includes an offset rod 61 that slides laterally on the inner wall of the housing 4. A wire hanging seat 62 is sleeved on the surface of the offset rod 61. A wire hanging wheel 63 is rotatably connected to the bottom of the wire hanging seat 62. A through groove is opened at the bottom of the housing 4. A first limiting rod 64 is fixedly connected to the inner wall of the through groove. A guide wheel 65 is sleeved on the surface of the first limiting rod 64 corresponding to the position of the wire hanging wheel 63. Several sets of wire hanging seats 62 are evenly arranged laterally on the surface of the offset rod 61. The synchronizing rod 66 is arranged in an "L" shape.

[0033] The guide wheel 65 is rotatably connected to the two sides of the synchronous rod 66. The other end of the synchronous rod 66 is limited and slidable in the protrusion on the side of the wire hanging seat 62. A steel wire 67 is fixedly connected to the wire hanging wheel 63. The steel wire 67 passes through the guide wheel 65 and is connected to the wire hanging wheel 63 in another set of housing 4. The offset rod 61 is provided with shaking components at both ends.

[0034] In one embodiment of the present invention, the shaking assembly includes a first bushing sleeved at both ends of the offset rod 61. A connecting rod 681 is fixedly connected to the back end of the first bushing. A sliding plate 682 is fixedly connected to the end of the connecting rod 681 away from the wire hanging seat 62. A first spring is fixedly connected to the back end of the sliding plate 682. The other end of the first spring is fixedly connected to the inner wall of the accommodating shell 4. An abutting rod 683 is fixedly connected between the connecting rods 681. A sliding block 684 is vertically limited and slidable on the inner wall of the accommodating shell 4 below the connecting rod 681. A driving rod 685 is rotatably connected to the end of the sliding block 684 away from the inner wall of the accommodating shell 4. An abutting block 686 is fixedly connected to the middle surface of the driving rod 685. The abutting block 686 is cam-shaped. The driving rod 685 is driven by a driving motor installed on the sliding block 684. When the two sets of abutting blocks 686 in the accommodating shell 4 rotate, they alternately abut against the abutting rod 683.

[0035] The drive motor continuously drives the drive rod 685 and the cam-shaped abutment block 686 to rotate. The rotating abutment block 686 pushes the abutment rod 683, which, together with the first springs at both ends, reciprocates and resets, causing the connecting rod 681 and the offset rod 61 to shift laterally as a whole, and finally causing the wire hanging seat 62, the wire hanging wheel 63 and the steel wire 67 to swing left and right.

[0036] In one embodiment of the present invention, the spacing adjustment mechanism includes a sliding groove formed on the bottom surface of the upper cavity of the housing 4. Several sets of adjustment rods 71 ​​are slidably limited inside the sliding groove. The several sets of adjustment rods 71 ​​are arranged in a "V" shape and are hinged to each other. The rear end of the adjustment rod 71 is slidably limited by a linkage rod 72 on the inner wall of the housing 4. The front end of the adjustment rod 71 is slidably limited by an offset plate 73 on the inner wall of the housing 4. The linkage rod 72 is driven by an electric push rod installed in the wire hanging seat 62.

[0037] The adjusting rod 71 consists of two sets of hinged rods. The two sets of hinged rods are hinged together at their near ends and rotatably connected on the surface of the linkage rod 72. The two sets of hinged rods slide in the groove opened on the surface of the offset plate 73 at their near and far ends. The middle top of the hinged rod is rotatably connected to the guide rod 74. The top of the wire hanging seat 62 extends into the upper cavity of the housing 4 and is fixedly connected to the fixing block 75. The end of the guide rod 74 away from the hinged rod slides within the fixing block 75. Adjusting components are provided at both ends of the top cavity of the wire hanging seat 62.

[0038] The electric push rod drives the linkage rod 72 to slide laterally along the inner wall of the housing 4. During the sliding process, the linkage rod 72 drives multiple sets of "V"-shaped adjusting rods 71, which are hinged to each other, to expand or retract synchronously. Each set of "V"-shaped adjusting rods 71 ​​consists of two sets of hinged rods, with the middle of the hinged rods rotatably connected to the guide rod 74. When the "V"-shaped adjusting rod 71 expands, the angle between the two hinged rods increases, causing the guide rod 74 and the fixing block 75 to move away from each other. When the "V"-shaped adjusting rod 71 retracts, the angle between the two hinged rods decreases, causing the guide rod 74 and the fixing block 75 to retract. The fixing block 75 is fixedly connected to the top of the wire hanging seat 62, thereby driving all the wire hanging seats 62 to move laterally along the surface of the offset rod 61, achieving equidistant synchronous displacement of all the wire hanging seats 62, and completing the uniform adjustment of the spacing of the entire row of steel wires 67 in one go.

[0039] In one embodiment of the present invention, the adjusting assembly includes a first oil tank 761 fixedly connected to both ends of the top chamber of the wire hanging seat 62. A first piston rod 762 is slidably limited within the first oil tank 761, and the output end of the first piston rod 762 is connected to the side end of the offset plate 73. A second oil tank 763 is fixedly connected to the bottom chamber of the wire hanging seat 62 below the sliding block 684. A second piston rod 764 is slidably limited within the second oil tank 763, and the output end of the second piston rod 764 is fixedly connected to the bottom of the sliding block 684. The oil chamber of the first oil tank 761 away from the offset plate 73 is connected to the top oil chamber of the second oil tank 763 through an oil delivery hose.

[0040] In one embodiment of the present invention, a second limiting rod 8 is laterally limited and slidable on the inner wall of the housing 4. The second limiting rod 8 passes through the middle of the hanging wheel 63. A guide groove 9 is provided on the surface of the second limiting rod 8. A guide rod 10 is fixedly connected to the inner wall of the hanging wheel 63 corresponding to the guide groove 9. The guide groove 9 is located on the surface of the second limiting rod 8 and is opened in a spiral structure. The second limiting rod 8 is limited and slidable within the guide groove 9.

[0041] The movement of the offset plate 73 can directly push the first piston rod 762 to slide back and forth inside the first oil tank 761. The chamber on the side of the first oil tank 761 away from the offset plate 73 is connected to the top chamber of the second oil tank 763 through an oil delivery hose. After the hydraulic oil in the first oil tank 761 is pressurized, it flows into the second oil tank 763 through the oil delivery hose, pushing the second piston rod 764 to rise or fall vertically.

[0042] Working principle: Operators control the extension and retraction of the electric push rod inside the wire-hanging seat 62 according to the specifications of the blocks and boards to be cut. The electric push rod drives the linkage rod 72 to slide laterally along the inner wall of the housing 4. During the sliding process, the linkage rod 72 drives multiple sets of "V"-shaped adjusting rods 71, which are hinged end-to-end, to expand or retract synchronously. Each set of "V"-shaped adjusting rods 71 ​​consists of two sets of hinged rods, with the middle of the hinged rods rotatably connected to the guide rod 74. When the "V"-shaped adjusting rod 71 expands, the angle between the two hinged rods increases, causing the guide rod 74 and the fixing block 75 to move away from each other. When the "V"-shaped adjusting rod 71 retracts, the angle between the two hinged rods decreases, causing the guide rod 74 and the fixing block 75 to retract. The fixing block 75 is fixedly connected to the top of the wire-hanging seat 62, thereby driving all the wire-hanging seats 62 to move laterally along the surface of the offset rod 61, achieving equidistant synchronous displacement of all the wire-hanging seats 62 and completing the uniform adjustment of the spacing of the entire row of steel wires 67 in one go.

[0043] During the process of adjusting the spacing of the wire-hanging seat 62 by unfolding and retracting the adjusting rod 71, the end of the hinge rod synchronously pushes the offset plate 73 to slide along the inner wall of the housing 4. The side end of the offset plate 73 is fixedly connected to the first piston rod 762. The movement of the offset plate 73 can directly push the first piston rod 762 to slide back and forth inside the first oil tank 761. The chamber on the side of the first oil tank 761 away from the offset plate 73 is connected to the top chamber of the second oil tank 763 through an oil delivery hose. After the hydraulic oil in the first oil tank 761 is pressurized, it flows into the second oil tank 763 through the oil delivery hose, pushing the second piston rod 764 to rise or fall vertically, causing the sliding block 684 to move up or down along the inner wall of the housing 4, thereby raising or lowering the drive rod 685 at the end of the sliding block 684, changing the installation height of the cam-shaped contact block 686. The drive motor continuously drives the drive rod 685 and the cam-shaped contact block 686 to rotate, and the contact block 686 rotates. The rotating push-off contact rod 683, in conjunction with the first springs at both ends, reciprocates and resets, causing the connecting rod 681 and the offset rod 61 to shift laterally. This ultimately causes the wire hanging seat 62, the wire hanging wheel 63, and the steel wire 67 to swing left and right. The cam-shaped contact block 686 moves downward, reducing the maximum stroke of the cam-pushing contact rod 683, decreasing the vibration offset of the offset rod 61, and simultaneously reducing the swing amplitude of the steel wire 67. The cam-shaped contact block 686 moves upward, increasing the maximum stroke of the cam-pushing contact rod 683, increasing the vibration offset of the offset rod 61, and simultaneously increasing the swing amplitude of the steel wire 67. At the same time, when the wire hanging seat 62 moves with the "V"-shaped adjusting rod 71 to change the spacing, the wire hanging seat 62 synchronously drives the wire hanging wheel 63 to shift laterally along the second limit rod 8. During the displacement, the guide rod 10 slides along the spiral guide groove 9, relying on the force of the spiral inclined surface to force the wire hanging wheel 63 to rotate autonomously and adaptively change the steel wire tension.

[0044] After the spacing, swing amplitude, and tension of the steel wires 67 are adjusted in an adaptive manner, the conveyor seat 1 transports the concrete block 5 to the cutting station. Then, the four corner vertical moving modules 2 of the conveyor seat 1 synchronously drive the mounting frame 3 and the housing 4 to move vertically downward as a whole, causing the entire row of steel wires 67 to press down and cut into the interior of the concrete block 5. Then, the drive motor continues to work, causing the cam-shaped abutment block 686 to rotate continuously. When the abutment blocks 686 in the two sets of housing 4 rotate, they abut against the abutment rod 683 in an alternating manner. With the first spring resetting, the offset rod 61 and the entire row of steel wires 67 continuously and slightly reciprocate, relying on the vibration peeling cutting method to cut the block longitudinally.

[0045] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
