Description

Technical Field

[0001] The utility model belongs to the technical field of brick production, and particularly relates to an anti-adhesion separation device for autoclaved aerated concrete blocks. Background Art

[0002] Steam-pressurized aerated concrete blocks are made from fly ash as the primary raw material, mixed with a foaming agent, and then stirred with water to create voids through a chemical reaction. The blocks are then cast, pre-cured, cut, and then autoclaved to create a highly dispersed, porous silicate building material. This material offers excellent sound and heat insulation, is lightweight, and is earthquake-resistant, making it a high-quality wall material. The production process for autoclaved aerated concrete blocks includes mixing with water, casting, cutting, and autoclaving. After curing in an autoclave, adjacent layers of concrete often adhere to each other, making them difficult to handle and stack. Therefore, these adhered layers must be separated. In the existing technology, a lifting mechanism is used to lift the cured concrete during the adhesion separation process of concrete blocks. When the concrete blocks are lifted to the upper clamping mechanism and the lower clamping mechanism, the upper clamping mechanism clamps the upper concrete blocks, and the lower clamping mechanism clamps the lower concrete blocks. The upper clamping mechanism is then driven up by a lifting cylinder to separate the upper and lower concrete blocks. Afterwards, the lifting mechanism drives the concrete blocks to rise layer by layer again, and the separation is carried out according to the above-mentioned separation method. The separation device of this structure has the following shortcomings during use: first, the lifting mechanism is used to lift the concrete blocks, and the lifting mechanism adopts a chain transmission structure. The bearing capacity of the chain transmission structure is limited. During use, the chain is easy to break. In addition, the chain has poor stability. The concrete blocks are prone to shaking during the overall movement, the operation is unstable, and the clamping mechanism is prone to misalignment. Second, the existing clamping mechanism does not have a buffering function during the clamping process. During the positioning and clamping process, the concrete blocks are often easily damaged due to excessive clamping force, which seriously affects the appearance quality of the concrete blocks. Therefore, it is an objective need to develop an anti-adhesion separation device for autoclaved aerated concrete blocks which has a reasonable structure, stable operation and significant use effect. Summary of the Invention

[0003] The purpose of the utility model is to provide an autoclaved aerated concrete block anti-adhesion separation device with reasonable structure, stable operation and significant use effect.

[0004] The object of the present utility model is achieved in this way, including a frame, a lifting mechanism and a separation mechanism, the frame includes two symmetrically arranged brackets, the tops of the two brackets are connected and fixed by a connecting frame, the lifting mechanism includes an adjusting screw, a sliding seat and a driver, the adjusting screw is rotatably mounted on the bracket, the sliding seat is processed with a threaded hole matching the adjusting screw, the sliding seat is screwed on the adjusting screw through the threaded hole, the driver is installed above the connecting frame and is transmission connected to the adjusting screw, the separation mechanism includes an upper clamping frame and a lower clamping frame arranged at intervals above and below, the two ends of the lower clamping frame are fixedly connected to the sliding seat, a plurality of lifting cylinders are symmetrically arranged on both sides above the lower clamping frame, the upper clamping frame is fixedly mounted on the top of the lifting cylinder, and a plurality of pneumatic clamping heads are symmetrically installed on both sides of the bottom surface of the upper clamping frame and on both sides of the top surface of the lower clamping frame.

[0005] Compared with the existing technology, the advantages of this device are: First, this device optimizes the structure of the lifting mechanism. The lifting mechanism adopts the lifting structure of the screw and the sliding seat, which can ensure the stability of the slider during the up and down lifting process, and ensure that the sliding seat always maintains vertical up and down movement. At the same time, the lifting mechanism is connected to the separation mechanism to drive the separation mechanism to move up and down, instead of the lifting mechanism driving the concrete block to move up and down. This device uses the lifting mechanism to drive the separation mechanism to move up and down to separate the fixed concrete blocks, which can avoid damage to the lifting mechanism or shaking of the concrete blocks, and can significantly improve the stability of the system operation. At the same time, this device optimizes the structure of the separation mechanism. The pneumatic clamping heads on the upper clamping frame and the lower clamping frame can ensure uniform clamping force on the concrete blocks, so that the concrete blocks can be quickly and completely separated from each other under the action of the jacking cylinder, which can completely avoid the phenomenon of damage to the surface of the concrete blocks caused by excessive clamping force, can effectively ensure the appearance quality of the product, has good use effect, and is easy to promote and use.

[0013] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited in any way. Any changes or improvements made based on the teachings of the present invention shall fall within the scope of protection of the present invention.

[0014] like Figures 1 to 6 As shown, the utility model comprises a frame 1, a lifting mechanism 2 and a separation mechanism 3, wherein the frame 1 comprises two symmetrically arranged brackets, the tops of the two brackets are connected and fixed by a connecting frame 11, and the connecting frame 11 is installed between the two brackets to ensure the stability of the brackets, the lifting mechanism 2 comprises an adjusting screw 21, a sliding seat 22 and a driver, the adjusting screw 21 is rotatably mounted on the bracket, the sliding seat 22 is machined with a threaded hole matching the adjusting screw 21, the sliding seat 22 is screwed to the adjusting screw 21 through the threaded hole, and the driver is installed on the connecting frame 11 The top is connected to the adjusting screw 21 in a transmission manner. The separation mechanism 3 includes an upper clamping frame 31 and a lower clamping frame 32 arranged at intervals above and below. The two ends of the lower clamping frame 32 are fixedly connected to the sliding seat 22. A plurality of lifting cylinders 33 are symmetrically arranged on both sides above the lower clamping frame 32. The lifting cylinder 33 is a structure used in the prior art. The finished product can be directly purchased according to the pressure and stroke size used. The upper clamping frame 31 is fixedly installed on the top of the lifting cylinder 33, and a plurality of pneumatic clamping heads 34 are symmetrically installed on both sides of the bottom surface of the upper clamping frame 31 and both sides of the top surface of the lower clamping frame 32.

[0015] After that, the driver controls the adjusting screw 21 to rotate, and drives the sliding seat 22 and the upper clamping frame 31 to move upward, and the lower clamping frame 32 also moves downward with the sliding seat 22. When the lower clamping frame 32 moves to both sides of the concrete block at the bottom layer, the pneumatic clamping heads 34 on both sides of the lower clamping frame 32 are used to clamp the two sides of the concrete block of the upper layer. The lifting mechanism 31 is actuated by the lifting mechanism 32, and the lifting mechanism 33 is actuated to move the lifting mechanism 32 upwards and downwards, thereby achieving the desired effect.

[0016] Furthermore, in order to ensure that the upper clamping frame 31 and the lower clamping frame 32 slide stably on the bracket and further improve the stability of the device operation, the bracket includes an upper top plate 12 and a lower bottom plate 13 arranged at intervals up and down, and two support columns 14 are installed between the upper top plate 12 and the lower bottom plate 13. Slide grooves are vertically processed on the support columns 14 on both sides of the upper clamping frame 31 and the lower clamping frame 32, and sliders matching the slide grooves are installed on the upper clamping frame 31 and the lower clamping frame 32. The sliders are slidably installed in the slide grooves, and the upper clamping frame 31 and the lower clamping frame 32 move up and down along the slide grooves, operate smoothly, and can ensure that the upper clamping frame 31 and the lower clamping frame 32 are always in a linear motion state during the up and down movement.

[0017] Furthermore, a guide rod 15 is installed between the upper top plate 12 and the lower bottom plate 13, and a guide slide hole corresponding to the guide rod 15 is installed on the sliding seat 22. The sliding seat 22 is slidably installed on the guide rod 15 through the guide slide hole. The guide rod 15 has a guiding function and can ensure the smooth up and down movement of the sliding seat 22.

[0018] Furthermore, the driver includes a driving motor 23, a driving pulley 24, a driven pulley 25 and a rotating shaft 26. The driving motor 23 is a structure used in the prior art and can be directly purchased as a finished product according to the power used. Two top seats 27 are installed vertically at intervals above the connecting frame 11. The rotating shaft 26 is rotatably installed on the top seat 27. The driving motor 23 is installed on the top of the connecting frame 11. The driving pulley 24 is installed on the output shaft of the driving motor 23. The driven pulley 25 is installed on the rotating shaft 26. The driving pulley 24 and the driven pulley 25 are connected by a transmission belt 28. The rotating shaft 26 and the adjusting screw 21 are connected by a gear transmission assembly 29. The gear transmission assembly 29 adopts two mutually meshing bevel gear mechanisms. When in use, the driving motor 23 drives the driving pulley 24 to rotate. The two rotating shafts 26 drive the adjusting screws 21 at both ends to rotate, and the sliding seat 22 on each side of the bracket moves along the two adjusting screws 21, which has better stability.

[0019] Furthermore, the pneumatic clamping head 34 includes a pushing cylinder 341, a fixing plate 342 and a clamping plate 343. The pushing cylinder 341 is a structure used in the prior art. The product can be directly purchased according to the pressure and stroke used. The cylinder seat of the pushing cylinder 341 is installed on the corresponding clamping frame, and the fixing plate 342 is installed on the end of the piston rod of the pushing cylinder 341. The clamping plate 343 is installed on one side of the fixing plate 342 through an elastic component, and movable holes are processed at both ends of the fixing plate 342. A movable rod 345 is slidably installed in the movable hole. The clamping plate 343 is installed at one end of the movable rod 345, and a limit block 346 is installed at the other end of the movable rod 345. There is a space between the limit block 346 and the fixed plate 342. A first spring 347 is installed on the movable rod 345 between the fixed plate 342 and the clamping plate 343, and a rubber layer 344 is provided on the surface of the clamping plate 343 away from the fixed plate 342. Preferably, the elastic component includes a second spring 348 and a pull rod 349, and a groove is provided on the fixed plate 342 close to the clamping plate 343. A connecting rod 3410 is installed in the groove, and two movable blocks 3411 are slidably installed on the connecting rod 3410. The second spring 348 is installed on the connecting rod 3410 between the two movable blocks 3411. There are two pull rods 349, one end of the pull rod 349 is rotatably connected to the movable block 3411, and the other end of the pull rod 349 is rotatably installed on the clamping plate 343. When the concrete block is clamped again, the pushing cylinders on both sides of the upper clamping frame 31 and the lower clamping frame 32 push the fixing plates 342 and the clamping plates 343 on both sides to move toward each other, thereby clamping the concrete block. When the clamping force of the clamping plates 343 on the concrete block is too great, the two clamping plates 343 can move away from each other and compress the first spring 347 for buffering. At the same time, the clamping plates 343 also drive the limit block 346 to move through the movable rod 345 and stretch the first spring 347. In this way, the deformation of the first spring 347 can offset part of the excessive force. The large clamping force, at the same time, when the two pull rods 349 rotate, the upper and lower movable blocks 3411 are also brought closer to each other and squeeze the second spring 348, so that the deformation of the second spring 348 can further offset a part of the excessive clamping force, and finally, can greatly offset the excessive clamping force when the two clamping plates 343 are clamped together, thereby avoiding the disadvantage of the existing clamping mechanism that the concrete blocks are easily damaged due to excessive clamping force during the clamping process due to the lack of a buffering function, thereby helping to ensure the quality of the appearance of the clamped concrete blocks.

[0020] Preferably, a rubber rod 3412 is obliquely arranged between the pull rod 349 on the side close to the movable rod 345 and the fixed plate 342. The rubber rod 3412 is made of rubber, and a third spring is arranged inside the rubber rod 3412. When the two clamping plates 343 move away from each other, the pull rod 349 rotates and stretches the rubber rod 3412 and the third spring inside the rubber rod 3412. In this way, through the deformation of the rubber itself of the rubber rod 3412 and the deformation of the third spring, a part of the excessive clamping force can be further consumed, so that the clamping force of the concrete block is more uniform and moderate.
