Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of block processing machines, and particularly relates to an aerated concrete block slotting device for building. BACKGROUND

[0002] An aerated concrete block is a kind of light building material. This material is widely used in wall and partition parts of residential, commercial and industrial buildings due to its light weight, good thermal insulation performance and convenient construction. In some application scenarios, such as the need to enhance structural strength, improve seismic resistance or increase the embedding depth of reinforced concrete, it is often necessary to slot the blocks.

[0003] Before the aerated concrete block is slotted, the handling link from the stacking area to the workbench usually uses a grabbing device to move the blocks one by one from the stacking site to the work platform of the slotting device. However, the shape of the aerated concrete block is various, but the clamp of the grabbing device can only match one shape.

[0004] When the aerated concrete block is slotted, if the shape changes after the batch of aerated concrete blocks is replaced, the staff must pause the production line, disassemble the original clamp and re-install, debug and adjust the device that matches the shape of the new batch of aerated concrete blocks, which destroys the continuity of the slotting operation.

[0060] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects more clearly understood, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0061] Please refer to Figures 1 to 6, the present invention is to describe the slotting equipment for aerated concrete blocks. A slotting equipment for aerated concrete blocks includes a loading unit 10, a positioning unit 20 and a slotting unit; the loading unit 10 includes two cutting conveyors 101 arranged opposite to each other along a first direction and a plurality of workbenches 102, the cutting conveyors 101 extending in the up-down direction, a working area being provided between the two cutting conveyors 101, and both sides of the workbenches 102 being detachably connected to the belt surfaces of the two cutting conveyors 101 located in the working area; the positioning unit 20 corresponds to the workbenches 102 one by one, and the positioning unit 20 is provided to the workbenches 102. Element 20 includes two support plates 201 relatively fixed to the workbench 102 along a first direction, a plurality of positioning rods 202 slidably connected to the support plates 201, and a first elastic member 203 fixed between the positioning rods 202 and the support plates 201. The first elastic member 203 has a pre-tightening force that makes the two positioning rods 202 approach each other. The first elastic member 203 is a spring or a spring rod; the slotting unit is provided on one side of the working area and is used for slotting concrete blocks. The slotting unit is a conventional milling device and will not be described in detail in this application.

[0062] Compared to existing technologies, the slotting equipment for aerated concrete blocks provided in this embodiment utilizes two cutting conveyors 101, positioned opposite each other along a first direction, as the equipment's main framework and power source. These two conveyors operate continuously, forming a vertical, circular conveying path. Multiple workbenches 102, detachably mounted on the belt surfaces of the cutting conveyors 101, serve as mobile carriers for the concrete blocks. While a block on a workbench 102 is being slotted, the upper workbench 102 can simultaneously load the blocks, while the lower workbench 102 can unload the blocks. This significantly reduces waiting time and improves the equipment's comprehensive utilization and overall production efficiency. The positioning unit 20 corresponds to each workbench 102 one by one, and includes two support plates 201 fixed to the workbench 102, multiple positioning rods 202 slidably connected to the support plates 201, and a first elastic member 203 that provides pre-tightening force. This arrangement forms a flexible "multi-finger" clamping system; when working, no matter how the size and side shape of the concrete block change, driven by the first elastic member 203, multiple positioning rods 202 can move forward simultaneously and independently until they fully contact both sides of the concrete block and apply uniform clamping force, thereby firmly holding the concrete block. This adaptive clamping mechanism does not require replacing special clamps for each new shape of concrete block. Just put the concrete block on the workbench 102, and the positioning unit 20 can automatically complete the centering and fixation, perfectly resolving the risk of production stoppage caused by product batch replacement and ensuring the smoothness and continuity of the grooving operation.

[0063] In some embodiments, the positioning unit 20 further comprises two pressing plates 204, two telescopic members 205, a plurality of pressing rods 206, and a plurality of second elastic members 207; the two pressing plates 204 are respectively arranged on the sides of the two supporting plates 201 away from each other, the pressing plates 204 are slidingly connected with the workbench 102 along the first direction, and the pressing plates 204 are provided with through grooves corresponding to the positioning rods 202; the two telescopic members 205 correspond to the pressing plates 204 one by one, the telescopic members 205 are fixedly connected between the pressing plates 204 and the workbench 102, the telescopic members 205 are telescopic along the first direction, and the telescopic members 205 are telescopic oil cylinders or hydraulic cylinders; the pressing rods 206 are arranged in the through grooves one by one, and the pressing rods 206 are slidingly connected with the pressing plates 204 along the first direction; the second elastic members 207 correspond to the pressing rods 206 one by one, the second elastic members 207 are fixedly connected between the pressing rods 206 and the pressing plates 204, the second elastic members 207 have a pre-tightening force for moving the pressing rods 206 towards the positioning rods 202, and the second elastic members 207 are springs or spring rods.

[0064] The telescopic members 205 are started, and the pressing plates 204 as a whole are pushed to move towards the concrete blocks. The movement of the pressing plates 204 simultaneously drives all the pressing rods 206 thereon to move forward. Due to the existence of the second elastic members 207, each pressing rod 206 is not rigidly fixed with the pressing plate 204, but can independently displace in the pressing plate 204. When the front ends of the pressing rods 206 contact the positioning rods 202 at different positions due to the surface profile of the concrete blocks, the second elastic members 207 allow the corresponding pressing rods 206 to displace relative to the pressing plate 204 for adjustment: the pressing rods 206 that contact earlier will be subjected to greater resistance, and the second elastic members 207 thereof are compressed to a greater extent; the pressing rods 206 that contact later or still have a gap continue to maintain the forward extension. This mechanism ensures that under the total thrust provided by the telescopic members 205, the final pressure applied by each pressing rod 206 to the corresponding positioning rod 202 is self-adaptive and balanced, so that all the positioning rods 202 can simultaneously and uniformly clamp the concrete blocks, thereby improving the clamping stability of the concrete blocks.

[0065] In some embodiments, the ends of the positioning rods 202 away from the pressing plates 204 are ball-hinged with supporting balls 2021, and the ball-hinged positions of the supporting balls 2021 and the positioning rods 202 are provided with dampings.

[0066] By introducing a ball-hinged, damped support ball 2021 at the end of the positioning rod 202, an upgrade from "rod-shaped linear clamping" to "spherical universal fitting" is achieved, and the core benefit is that it completely eliminates the hard contact problem between the traditional rigid clamp and the aerated concrete block surface. The design forms a spherical contact between the support ball 2021 and the concrete block surface, which uniformly disperses the huge clamping force to a larger area, greatly reducing the pressure, and fundamentally avoiding the risk of crushing, indentation or local collapse of the block surface during tightening and processing, perfectly protecting the integrity of the workpiece. At the same time, the ball-hinged structure gives each clamping point infinite azimuthal freedom, so that whether the concrete block side wall is vertical, inclined or irregular curved, the support ball 2021 can automatically adjust the angle so that its spherical surface always optimally fits the concrete block surface. This not only maximizes the contact area, but also ensures that the clamping force is always perpendicular to the tangent at the contact point, thereby providing stable multi-point gripping effect, greatly enhancing the anti-vibration and anti-torsion capability of the concrete block during slotting operation. The built-in damping mechanism is the key guarantee for high-precision processing, which effectively suppresses the residual shaking and slight trembling of the support ball 2021 after finding the angle and under external vibration, so that it can quickly stabilize and lock in the optimal position, like an invisible "mechanical hand" firmly holding the block while also cushioning with soft and stable sponge, thereby highly unifying the flexibility and adaptability of the clamping system with the rigidity and stability of the two seemingly contradictory characteristics, providing a precise processing reference for the subsequent slotting process.

[0067] In some embodiments, the feeding unit 10 further comprises a plurality of connecting structures spaced apart on the belt surface of the cutting conveyor 101, and the bottom of the workbench 102 is provided with a connecting groove 1021.

[0068] The connecting structure comprises a connecting seat 103, a connecting column 104, a first deformation member 105, a push-out member 106, and an outward-expanding member. The connecting seat 103 is fixed to the outer side of the belt of the cutting conveyor 101, and a sliding groove 1031 is formed on the side of the connecting seat 103 away from the cutting conveyor 101. A power groove 1032 is also formed in the connecting seat 103 and communicates with the sliding groove 1031. The connecting column 104 is arranged in the sliding groove 1031 and is slidingly connected to the connecting seat 103 along the movement direction of the belt of the cutting conveyor 101. The connecting column 104 is also adapted to be inserted into the connecting groove 1021. The first deformation member 105 is fixed between the connecting column 104 and the connecting seat 103 and has a pre-tightening force for allowing the connecting column 104 to be received in the sliding groove 1031. The first deformation member 105 is a spring or a spring rod. The push-out member 106 is fixed to the inner wall of the power groove 1032. The extension direction of the push-out member 106 is perpendicular to the movement direction of the connecting column 104. The push-out member 106 is an extension oil cylinder or a hydraulic cylinder. The extension end of the push-out member 106 abuts against the connecting column 104. The connecting column 104 is provided with a first pressure surface abutting against the extension end of the push-out member 106. The outward-expanding member is connected to the outer wall of the connecting column 104. The outward-expanding member has a first working state of expanding outwardly from the connecting column 104 and a second working state of being received in the connecting column 104.

[0069] When the workbench 102 needs to be installed, the connecting groove 1021 at the bottom of the workbench 102 is aligned with the sliding groove 1031. The connecting column 104 is normally kept in a retracted state under the pre-tightening force of the first deformation member 105. The connecting column 104 is inserted into the connecting groove 1021 by the push-out member 106 pressing the first pressure surface. Then, the outward-expanding member expands outwardly from the inside or the side of the connecting column 104, so that the outward-expanding member abuts against the inner wall of the connecting groove 1021, thereby connecting and fixing the workbench 102 to the cutting conveyor 101, and allowing the workbench 102 to stably run with the belt of the cutting conveyor 101 to each work station.

[0070] When the workbench 102 needs to be separated from the cutting conveyor 101, the push-out member 106 is retracted, so that the outward-expanding member is retracted. The push-out member 106 is continuously retracted, and the connecting column 104 is received in the sliding groove 1031 by the first deformation member 105, thereby releasing the mechanical interlocking, so that the workbench 102 can be smoothly separated from the cutting conveyor 101. The entire process does not require manual intervention and is automatically completed by the mechanical structure linkage, which greatly improves the production rhythm and the intelligent level of the equipment.

[0071] In some embodiments, the outer wall of the connecting column 104 is provided with a receiving groove 1041, and the connecting column 104 is provided with an extrusion groove 1042 communicating with the receiving groove 1041. The connecting structure further comprises a clamping block 107, a second deformation member 108, and an extrusion column 109. The clamping block 107 forms the above-mentioned expansion member, and is arranged in the receiving groove 1041 and in sliding connection with the receiving groove 1041. The clamping block 107 moves along the radial direction of the connecting column 104, and is provided with a second pressure surface for extrusion by the extrusion column 109. The second deformation member 108 is fixed between the clamping block 107 and the connecting column 104, and has a pre-tightening force for allowing the clamping block 107 to be received in the receiving groove 1041. The second deformation member 108 is a spring or a spring rod. The extrusion column 109 is arranged in the extrusion groove 1042 and in sliding connection with the connecting column 104. The extrusion column 109 moves along the axial direction of the connecting column 104, and is further provided with a third pressure surface for extrusion by the telescopic end of the pusher 106.

[0072] Specifically, the inner wall of the connecting groove 1021 is provided with a clamping groove 1022 adapted for clamping connection with the clamping block 107.

[0073] When the connecting column 104 is not subjected to external force, the clamping block 107 is retracted under the action of the second deformation member 108, and the connecting column 104 can be freely inserted into or pulled out of the connecting groove 1021 of the workbench 102. When the connecting column 104 is inserted into the connecting groove 1021 and in place, the pusher pushes the extrusion column 109 to move. The extrusion column 109 forcibly overcomes the force of the second deformation member 108 by extruding the second pressure surface, and pushes the clamping block 107 radially outward from the receiving groove 1041, so that the clamping block 107 is clamped into the clamping groove 1022, thereby realizing the rigid connection and power transmission between the workbench 102 and the cutting conveyor 101.

[0074] When separation is required, the pusher 106 is retracted, the radial constraint on the clamping block 107 is immediately released, and the clamping block 107 is retracted into the receiving groove 1041 under the action of the second deformation member 108, thereby completely releasing the mechanical interlocking and allowing the connecting column 104 to be withdrawn from the connecting groove 1021. The entire process realizes self-locking and unlocking of the connection through a purely mechanical mode, avoids complex sensing and control, and greatly enhances the reliability and durability of the system in an industrial environment.

[0075] Another deformed embodiment of the outer expansion piece is that the outer wall of the connecting column 104 is provided with a receiving groove 1041, and the connecting column 104 is provided with an extrusion groove 1042 in communication with the receiving groove 1041. The connecting structure further comprises an expansion air bag 110 forming the outer expansion piece and a gas pressing column 111 arranged in the extrusion groove 1042. The expansion air bag 110 is arranged in the receiving groove 1041 and in communication with the extrusion groove 1042. The gas pressing column 111 is in sliding connection with the connecting column 104. The gas pressing column 111 moves along the axial direction of the connecting column 104. The gas pressing column 111 is further provided with a third pressure surface for extrusion of the telescopic end of the pushing piece 106.

[0076] When the connecting column 104 is not subjected to external force, the expansion air bag 110 is in an unexpanded state under the action of the second deformation piece 108, and the connecting column 104 can be freely inserted into or pulled out of the connecting groove 1021 of the workbench 102. When the connecting column 104 is inserted into the connecting groove 1021 and in place, the pushing piece pushes the gas pressing column 111 to move, and the gas pressing column 111 pushes the gas pressure in the extrusion groove 1042 into the expansion air bag 110, so that the expansion air bag 110 expands and tightly abuts against the inner wall of the connecting groove 1021, thereby realizing the rigid connection and power transmission of the workbench 102 and the cutting and conveying machine 101.

[0077] When separation is needed, the pushing piece 106 is retracted, and the gas pressing column 111 is reset so that the gas in the expansion air bag 110 is returned to the extrusion groove 1042, thereby reducing the expansion air bag 110 and completely releasing the mechanical interlocking, so that the connecting column 104 can be withdrawn from the connecting groove 1021. The whole process realizes the self-locking and unlocking of the connection by a pure mechanical mode, avoids complex sensing and control, and greatly enhances the reliability and durability of the system in an industrial environment.

[0078] In some embodiments, the top surface of the workbench 102 is inwardly recessed to form a discharging groove 1023, and the discharging groove 1023 is provided with a plurality of discharging rollers 1024 and a discharging member in driving connection with the discharging rollers 1024. The discharging rollers 1024 are in rotary connection with the workbench 102, and the rotary shafts of the discharging rollers 1024 are parallel to the first direction. The discharging member is used to drive the discharging rollers 1024 to rotate, and the discharging member is a servo motor.

[0079] The lower part of the slotting unit is provided with a discharging conveyor 30, and the discharging conveyor 30 is arranged on the ground. The extension direction of the discharging conveyor 30 is perpendicular to the extension direction of the cutting and conveying machine 101.

[0080] After the concrete block is processed, the discharging member is started to drive the discharging rollers 1024 to rotate, and the discharging rollers 1024 rotate to convey the processed concrete block to the discharging conveyor.
