Description

Technical Field

[0001] The invention relates to the technical field of sintered block cutting and grinding, in particular to an automatic sintered block cutting and grinding machine. Background Art

[0002] Prefabricated buildings in my country are in the early stages. As economies of scale cannot be realized quickly for the time being, many difficulties are encountered in the short term, such as rising costs, developers waiting and watching, insufficient construction experience, lack of technical reserves and many other problems. In the future, this situation will change. The trend of technological development is from a closed system to an open system, standardization and modularization of functional blocks, modules, etc., as well as personalized integration, which will eventually form a standardized, modular and integrated prefabricated building system. In the future, green prefabricated buildings are an important symbol of the development of building industrialization and industrial modernization. New green prefabricated building systems will inevitably be widely used in future buildings. The automatic sintered block cutting and grinding machine is mainly used for cutting and grinding on both sides of sintered blocks, removing the burrs on both sides of the sintered blocks, making the surfaces on both sides smooth and flat, providing precision guarantee for the subsequent masonry walls of sintered blocks, and providing high-quality wall building materials for prefabricated buildings such as industrial automation insulation filling and industrial automation walling.

[0003] Before leaving the factory, sintered blocks need to be ground and trimmed one by one to make their size specifications meet the set requirements. Grinding and trimming can remove burrs and irregular parts on the surface of sintered blocks, ensure the uniform quality of each brick, improve the appearance quality of sintered blocks, and enhance their structural performance and service life. At the same time, during the production process, sintered blocks may have different sizes due to raw materials, mold wear or slight deviations in the production process. Through grinding and trimming, the size of each brick can be made to meet the set specifications, ensuring the interchangeability and matching of sintered blocks in actual use, and standard-sized sintered blocks are easier to arrange during construction. The sintered blocks are neatly arranged, which reduces the workload of on-site cutting and adjustment and improves construction efficiency. At the same time, sintered blocks with precise dimensions can ensure that the overall structure of the wall or building is more stable and reduce the need for later repairs and maintenance. The surface of the sintered blocks after grinding and trimming is smoother and flatter, which helps to improve the overall aesthetics of the building. For some construction projects that require high appearance quality, especially exterior walls and decorative sintered blocks, the unification of size and surface quality is particularly important. Finally, through grinding and trimming, some sintered blocks that are close to the scrap standard can be trimmed into qualified products that meet the specifications, reducing the production scrap rate and saving resources and costs.

[0004] The Chinese patent with the existing authorization announcement number CN212794405U discloses a construction waste brick cutting, grinding and recycling device, including a shell and a rotating plate, the rotating plate is arranged inside the shell and the left end is rotatably connected to the side wall of the shell through a first rotating rod, a support rod is arranged in the middle of the upper surface of the rotating plate, the upper end of the support rod is rotatably connected to a placement plate through a rotating shaft, a hydraulic cylinder is arranged at the bottom right end of the shell and a rotating block is fixedly arranged at the end of the piston rod of the hydraulic cylinder, the rotating block is rotatably connected to the right lower end of the rotating plate through an axle pin, a second rotating rod is arranged above the placement plate, a plurality of grinding blades are fixedly arranged on the rod wall of the second rotating rod, a first motor is arranged at the rear side of the shell and the output end of the first motor is fixedly connected to the rear end of the second rotating rod. The utility model can grind the waste bricks evenly and fully, and can prevent the bricks from being impacted and broken during collection.

[0005] However, since the above patent solution cannot realize automated assembly line grinding, it needs manual disassembly and installation, and cannot realize synchronous feeding and centering clamping. In addition, during the grinding and cutting process, the blade may easily overheat and become scrapped and need to be cooled. The dust will also affect the environment and the health of the operators. The existing sintered block cutting and grinding device cannot be adjusted and reset in time after being skewed and misaligned, resulting in high scrap rate, low processing accuracy and other problems that need to be solved urgently.

DETAILED DESCRIPTION

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0036] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0037] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0038] Example 1

[0039] Reference Figure 1 to Figure 8 , which is the first embodiment of the present invention, provides an automated sintered block cutting and grinding machine, including a synchronous feeding mechanism 100, a cutting and grinding mechanism 200 and a cooling and dust prevention mechanism 300. The synchronous belt 104 ensures that the sintered block 103 can move synchronously, and is transported to the cutting wheel 201 and the grinding wheel 202 through the upper and lower belts for cutting and grinding. The spacing between the synchronous belts 104 and the spacing between the upper and lower belts are adjustable to accommodate sintered blocks 103 of different specifications. The upper and lower belts can be centered and clamped to prevent the sintered block from moving and dislocating during the cutting process, and the maximum amount of coolant is controlled according to the height of the sintered block 103 for dust removal and cooling to reduce waste.

[0040] Specifically, it includes a synchronous feeding mechanism 100, including a base 101, a bracket 102 fixed on the base 101, and a sintered block 103. A synchronous belt 104 is provided at one feeding end of the base 101, and the sintered block 103 is adjusted in position when following the synchronous belt 104. A lower belt 1011 is provided on the inner wall of the base 101, and the sintered block 103 moves following the lower belt 1011 under the limit of the bracket 102.

[0041] The cutting and grinding mechanism 200 includes a cutting wheel 201 and a grinding wheel 202 which are simultaneously rotated at the lower end of the bracket 102, a conveying roller 1021 which is rotated at the upper end of the bracket 102, and an upper belt 1022 which is sleeved on the outer wall of the conveying roller 1021. A push plate 1023 is provided on the inner wall of the upper belt 1022. The push plate 1023 pushes the upper belt 1022 to fit with the sintered block 103. The upper belt 1022 and the lower belt 1011 fit with the upper and lower surfaces of the sintered block 103 respectively.

[0042] The cooling and dust-proof mechanism 300 includes a watering bin 301 disposed on the outer wall of the push plate 1023. The watering bin 301 sprays coolant onto the upper end surface of the sintered block 103. The watering speed of the watering bin 301 increases as the moving speed of the sintered block 103 increases. When the sintered block 103 is dislocated, the watering bin 301 sprays water in the opposite direction to push the sintered block 103 to return to its original position.

[0043] Among them, the lower belt 1011 is responsible for driving and transporting the sintered blocks 103 in sequence, and the sintered blocks 103 are transmitted in sequence to fit with the upper belt 1022. The upper belt 1022 is symmetrically provided with two sets to jointly center and limit the sintered blocks 103, which can fix the position of the sintered blocks and ensure that the sintered blocks will not move during the cutting and grinding process. The speed and direction of the lower belt are adjusted according to the production plan.

[0044] Among them, two cutting wheels 201 and two grinding wheels 202 are symmetrically arranged, which are respectively responsible for cutting and grinding the two sides of the sintered block 103. The width of the cutting wheel 201 and the grinding wheel 202 is adjustable and adjusted according to different product specifications to ensure that each sintered block 103 is cut and ground to the set specifications.

[0045] Preferably, the relative spacing between the upper belt 1022 and the lower belt 1011 can be adjusted by a cylinder to meet the production requirements of sintered blocks 103 of different widths. The spacing between the synchronous belts 104 can also be adjusted by a cylinder so that sintered blocks 103 of different specifications and sizes can be fed synchronously.

[0046] Preferably, the bracket 102 is a tic-tac-toe frame, the conveying roller 1021 is arranged on the upper horizontal plate of the bracket 102, the cutting wheel 201 and the grinding wheel 202 are arranged on the lower horizontal plate of the bracket 102, and the cutting wheel 201 and the grinding wheel 202, the conveying roller 1021 and the lower belt 1011 are all driven by a servo motor.

[0047] Among them, a liquid inlet tube 105 is fixedly provided on the upper end surface of the bracket 102, and a liquid infusion tube 1051 is slidably provided inside the liquid inlet tube 105. A groove 1052 is opened on the outer wall of the liquid infusion tube 1051, and a confluence cavity 1053 is opened on the inner wall of the liquid inlet tube 105. When the groove 1052 and the confluence cavity 1053 overlap, the liquid inlet tube 105 and the liquid infusion tube 1051 are connected.

[0048] The inner wall of the liquid inlet tube 105 is provided with a guide hole 1054 , and both ends of the guide hole 1054 are respectively connected to the confluence cavity 1053 and the upper side of the inner wall of the liquid inlet tube 105 . A first elastic member 1055 is provided between the infusion tube 1051 and the bracket 102 .

[0049] Furthermore, the notch 1052 is in an inverted triangle shape, so that the further downward the infusion tube 1051 is, the smaller the maximum coolant flow rate in the infusion tube 1051 is. When processing smaller sized sintered blocks 103, the flow rate is automatically reduced to prevent waste. When processing higher sized sintered blocks 103, the coolant flow rate is increased to improve the cooling and dust prevention effects.

[0050] Preferably, one end of the liquid infusion tube 1051 slides out of the liquid inlet tube 105 and communicates with the push plate 1023, and the coolant is spread from the push plate 1023 and the watering bin 301 to the surface of the sintered block 103, cooling the cutting wheel 201 and the grinding wheel 202, and eliminating dust and powder generated by cutting.

[0051] Among them, the first elastic member 1055 is a spring. Under the push of the first elastic member 1055, the infusion tube 1051 and the push plate 1023 always have a tendency to approach and fit the sintered block 103, and push the upper belt 1022 to always fit the upper end surface of the sintered block 103. The push plate 1023 slides and fits with the inner wall of the upper belt 1022, and the two can slide relative to each other.

[0052] More preferably, the cutting wheel 201 and the grinding wheel 202 as well as the driving motor are all controlled to move by the motor screw, so that the cutting wheel 201 and the grinding wheel 202 are adjusted to move to corresponding positions according to the processing requirements of different batches of sintered blocks to obtain different processing effects.

[0053] Among them, in this embodiment, the upper belt 1022 and the lower belt 1011 can be driven by the screw rod to move synchronously, so that the two belts can be close to or away from each other, thereby realizing the adjustment of the fixed position of the sintered blocks. The fixed position is adjusted according to the sintered blocks of different processing sizes to achieve the best fixing effect.

[0054] In summary, when in use, the distance between each belt is set according to the size of the sintered block 103 to be cut and polished, and the spacing between the cutting wheel 201 and the polishing wheel 202 is adjusted at the same time. Then, the sintered block 103 is placed on the lower belt 1011 on the base 101. Driven by the servo motor, the sintered block 103 starts to move and enter the synchronous belt 104, and is driven by the synchronous belt 104 to adjust its position, so as to facilitate subsequent synchronous cutting and polishing. Then, it is fitted with the upper belt 1022. The push plate 1023 automatically contacts the upper surface of the sintered block 103 and presses it to fix it under the push of the first elastic member 1055 to prevent displacement during the cutting process. Finally, the two sides are cut and polished to obtain the sintered block 103 of the required specifications and dimensions.

[0055] At the same time, the surfaces of the cutting wheel 201 and the grinding wheel 202 are cooled by the coolant, and the dust and powder generated during cutting and grinding are absorbed by the coolant to prevent the operator from being affected. When the sintered block 103 is shorter, the infusion tube 1051 is moved downward under the drive of the first elastic member 1055, and the inverted triangle-shaped notch 1052 moves downward, so that the overlapping area of ​​the confluence cavity 1053 and the confluence cavity 1053 is reduced, and the coolant flow rate is reduced to prevent waste. Similarly, when processing sintered blocks 103 of higher sizes, the coolant flow rate is increased to improve the cooling and dust prevention effects; when performing maintenance, the infusion tube 1051 is pushed to the top to block the opening of the guide hole 1054 located on the upper side of the inner wall of the liquid inlet tube 105 to achieve complete closure of the coolant. At the same time, when no sintered block 103 passes, the infusion tube 1051 is at the lowest point under the push of the spring, and the coolant is also closed, thereby realizing automatic adjustment and switching of the coolant flow rate.

[0056] Example 2

[0057] Reference Figure 1 to Figure 8 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but is different in that the coolant outlet speed is controlled by the moving speed of the sintered block 103 on the upper and lower belts. The faster the sintered block 103 moves, the faster the cutting and grinding efficiency is, the faster the dust is generated, and the more cooling is needed. At this time, the larger the coolant flow rate is, the more sufficient cooling and dust removal can be performed.

[0058] Specifically, a cylindrical cavity 1024 is opened in the push plate 1023 , an impeller 1025 is rotatably arranged in the cylindrical cavity 1024 , the infusion tube 1051 is connected to the cylindrical cavity 1024 , and one side blade of the impeller 1025 is aligned with the outlet of the infusion tube 1051 .

[0059] Among them, the impeller 1025 and the inner wall of the cylindrical cavity 1024 are sealed to prevent water leakage. The impeller 1025 is provided with six blades in total. The axis of the impeller 1025 is eccentrically arranged with the outlet of the infusion tube 1051, so that when the coolant on the infusion tube 1051 flows down, it flows into a certain blade, and when the blade rotates, it drives the coolant into the cylindrical cavity 1024.

[0060] A rotating shaft 1026 is provided at the axis of the impeller 1025 , and the rotating shaft 1026 rotates through the push plate 1023 . A rotating groove 1027 and a limiting groove 1028 are opened in the rotating shaft 1026 , and a driving shaft 1029 is also slidably provided in the rotating shaft 1026 .

[0061] More preferably, a block 1031 is provided on the outer wall of the driving shaft 1029, the block 1031 is slidably arranged in the limiting groove 1028 and rotates in the rotating groove 1027, a speed measuring wheel 1032 is rotated in the watering bin 301, and the driving shaft 1029 is fixedly connected to the center of the speed measuring wheel 1032.

[0062] Furthermore, the block 1031 is waist-shaped, and the block 1031 and the driving shaft 1029 can slide in the limiting groove 1028, but cannot rotate relative to each other, so that the rotating shaft 1026 is driven to rotate through the driving shaft 1029. When the block 1031 is in the rotating groove 1027, the block 1031 rotates freely and cannot drive the rotating shaft 1026 to rotate.

[0063] In this embodiment, the tachometer wheel 1032 is in direct contact with the surface of the sintered block 103, and drives the tachometer wheel 1032 to rotate while the sintered block 103 moves. The greater the moving speed, the faster the rotation speed of the tachometer wheel 1032.

[0064] In summary, when in use, the speed measuring wheel 1032 moves and rotates along the surface of the sintered block 103, driving the driving shaft 1029 to rotate. At this time, the block 1031 is located in the limiting groove 1028, thereby driving the rotating shaft 1026 and the impeller 1025 to rotate. As the impeller 1025 rotates, the coolant flowing into the cylindrical cavity 1024 is brought into the cylindrical cavity 1024 through the blades. The coolant flows into the cylindrical cavity 1024 from the infusion pipe 1051 and flows into the watering bin 301 along the push plate 1023, and is spread from the opening on the bottom of the watering bin 301 to the surface of the sintered block 103. The faster the sintered block 103 moves with the conveyor belt, the faster the cutting and grinding efficiency is, the faster the dust is generated, and the more cooling is needed. At this time, the larger the coolant flow rate is, the more sufficient cooling and dust removal can be performed.

[0065] At the same time, the drive shaft 1029 is pulled out from the rotating groove 1027 into the rotating groove 1027. At this time, the drive shaft 1029 and the rotating shaft 1026 no longer rotate together, the rotation speed of the impeller 1025 is not limited, the coolant is fully sprayed, and the linkage between the moving speed of the sintered block 103 and the coolant spraying speed is released.

[0066] Example 3

[0067] Reference Figure 1-Figure 8 , which is the third embodiment of the present invention. This embodiment is based on the previous embodiment, but differs in that the coolant is sprayed in a cyclic and uniform direction. When the sintered block 103 deviates after cutting, the restriction of the liquid level by the impeller 1025 is released, and at the same time, a large flow of coolant is sprayed along the inner liquid spray port 3015 to push the sintered block 103 to reset, thereby achieving deviation correction.

[0068] Specifically, a cylinder 3012 is slidably penetrated through the watering bin 301 , and a meshing wheel 3011 is rotatably provided on one end surface of the cylinder 3012 . The meshing wheel 3011 is meshed and connected with the speed measuring wheel 1032 , and the meshing wheel 3011 rolls along the surface of the sintered block 103 .

[0069] The outer wall of the cylinder 3012 is sleeved with a second elastic member 3013 , and the two ends of the second elastic member 3013 are respectively connected to the outer wall of the watering bin 301 and the outer wall of the meshing wheel 3011 . A connecting rod 3032 is rotatably provided at one end of the cylinder 3012 away from the meshing wheel 3011 .

[0070] Furthermore, both ends of the connecting rod 3032 are rotatably connected to the cylinder 3012 and the driving shaft 1029 respectively, so that when the cylinder 3012 moves axially, the driving shaft 1029 can be driven to move by the connecting rod 3032. The second elastic member 3013 is a spring, which pushes the meshing wheel 3011 to always move toward the center of the sintered block 103.

[0071] Preferably, the outer wall of the cylinder 3012 is provided with a deviation correction wheel 3021 , the bottom surface of the watering bin 301 is provided with a shower tank 3014 , the shower tank 3014 is provided with a liquid spraying port 3015 , a reversing wheel 3016 is rotatably provided in the shower tank 3014 , and the reversing wheel 3016 is provided with a water trough 3037 .

[0072] Among them, three water troughs 3037 are opened in a circular array on the outer wall of the reversing wheel 3016, and the spray port 3015 is opened in an array on the shower tank 3014. When the spray port 3015 coincides with the water trough 3037, they are connected, and the coolant is sprayed out therefrom, and the spraying direction is the same as that of the spray port 3015. The deviation correction wheel 3021 is attached to the outer wall of the sintered block 103 and guides and limits it to prevent tilting.

[0073] More preferably, there are five liquid spraying ports 3015, which are symmetrically distributed on the outer wall of the bottom surface of the shower tank 3014, the reversing wheel 3016 is slidably fitted with the inner wall of the shower tank 3014, and only one water tank 3037 on the reversing wheel 3016 enters the area where the five liquid spraying ports 3015 are located at a time, so that when the reversing wheel 3016 rotates, the five liquid spraying ports 3015 spray water in sequence, and the cutting wheel 201 and the grinding wheel 202 and the surface of the sintered block 103 are evenly sprayed, so as to eliminate dust everywhere.

[0074] Furthermore, a linkage shaft 3017 is provided at the axis of the reversing wheel 3016 . The linkage shaft 3017 slides through the shower tank 3014 and is provided with a first bevel gear 3018 . A spring 3019 is provided between the linkage shaft 3017 and the outer wall of the watering bin 301 .

[0075] Among them, a relay wheel 3022 is rotatably provided on the outer wall of the watering bin 301 , one side of the relay wheel 3022 is meshed with the deviation correction wheel 3021 , and the other side of the relay wheel 3022 is meshed with a second bevel gear 3023 , and the first bevel gear 3018 is meshed and connected with the second bevel gear 3023 .

[0076] Preferably, the correcting wheel 3021 is separated from the relay wheel 3022 when moving along the axial direction. At this time, under the action of the clockwork spring 3019, the linkage shaft 3017 is rotated to the innermost side. At this time, the water groove 3037 of the reversing wheel 3016 coincides with the inwardly inclined liquid spraying port 3015 on the shower tank 3014, so that the liquid spraying port 3015 continues to spray in this direction. During the rotation of the correcting wheel 3021 along the surface of the sintered block 103, the residual burrs on the surface thereof will also be smoothed to prevent personal injury.

[0077] In summary, during normal use, the coolant enters the watering bin 301. At this time, as the meshing wheel 3011 rolls along the surface of the sintered block 103, the speed measuring wheel 1032 is driven to rotate, thereby driving the coolant to flow down. At this time, the correcting wheel 3021 also rolls along the outer wall of the sintered block 103 driven by the cylinder 3012, and drives the relay wheel 3022 and the second bevel gear 3023 to rotate, and finally drives the linkage shaft 3017 to rotate through the first bevel gear 3018, so that the reversing wheel 3016 rotates along the shower tank 3014, and sprays the coolant along each spray port 3015 to various places of the sintered block 103, the grinding wheel 202 and the cutting wheel 201 to perform large-scale dust removal, and at the same time, the tool and the mold are evenly cooled.

[0078] At the same time, when the sintered block 103 deflects after cutting and the moving trajectory deviates from the center, the sintered block 103 deflects in one direction. At this time, the correcting wheel 3021 attached to the outer wall of the sintered block 103 also deflects and dislocates. The correcting wheel 3021 and the cylinder 3012 move synchronously in the deflection direction of the sintered block 103, and at the same time, the driving shaft 1029 is driven to separate from the rotating shaft 1026 through the connecting rod 3032. At this time, the coolant flow rate reaches a maximum, and at the same time, the correcting wheel 3021 moves outward along the axial direction and separates from the relay wheel 3022. Under the action of the clockwork spring 3019, the rotation The linkage shaft 3017 is turned to the innermost side. At this time, the water tank 3037 of the reversing wheel 3016 coincides with the inwardly inclined liquid spraying port 3015 on the shower tank 3014, so that the liquid spraying port 3015 continues to spray in this direction. Under normal circumstances, the coolant flows away quickly, but because the coolant flow rate is the largest at this time and the spraying direction continues to be inward, the sintered block 103 will move inward slightly under the lubrication of the coolant itself. When the sintered block 103 is reset, the correcting wheel 3021 is reset, and the coolant resumes to uniform reciprocating spraying, thereby realizing automatic correction of the direction of the sintered block 103.
