Description

Technical Field

[0001] This invention relates to the field of fluidity testing technology, and in particular to a fluidity testing device for decorative mortar production. Background Technology

[0002] As a thin-layer decorative material, the fluidity of finishing mortar directly determines its workability and final decorative effect. If the fluidity is too high, the mortar will sag under gravity after being applied to the wall, ruining the texture; if the fluidity is too low, the trowel will encounter high resistance when scraping, easily leaving trowel marks, and it will be difficult to cover defects in the substrate. Furthermore, finishing mortar formulations contain thixotropic components such as adhesive powder and cellulose ethers, and their "statically thick, dynamically thin" characteristic needs to be precisely quantified—the initial flow rate affects construction efficiency, while the thixotropic recovery time determines the resistance to sagging.

[0003] A search revealed Chinese patent publication number CN219675765U, which discloses a high-stability and high-precision flowability measuring instrument, comprising a frame, a sliding column, a jumping table, a conical mold, and a cam. The frame slides vertically in conjunction with the sliding column, and the wheel surface of the cam is positioned corresponding to the lower end of the sliding column. The rotating cam pushes the sliding column upward. The sliding column or the jumping table is provided with a limiting element, which restricts the downward sliding stroke of the sliding column. When the sliding column slides downward to its lowest point, a safety gap is provided between the minimum diameter of the outer wheel surface of the cam and the lower end of the sliding column.

[0004] The above-mentioned patent has the following shortcomings: the finishing mortar is not self-leveling; it is spread out after being sheared by a trowel / spray gun, and the pure vertical jumping table testing method is out of touch with real working conditions. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a flowability testing device for decorative mortar production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A flowability testing device for decorative mortar production includes a base, a gantry frame is fixed to the top outer wall of the base by bolts, a bearing plate assembly is provided on the inner side of the middle of the base, and a truncated cone mold assembly is provided on the top of the bearing plate assembly. The carrier disk assembly includes: An offset ring is rotatably connected to the inner side of the base via a connecting shaft and can rotate along the axis of the connecting shaft under a rotational driving torque. A turntable, which is rotatably connected to the inner wall of the offset ring and can be rotated along its own axis by a rotational driving torque; A support plate that supports the finishing mortar, and the support plate is slidably connected to the top of the turntable via guide posts; The top of the base is also provided with an eccentric drive mechanism that drives the guide column to rise through eccentric motion.

[0007] Preferably, a telescopic rod is rotatably connected to one side wall of the gantry frame, a swing arm is fixed to the outer wall of the connecting shaft, and the telescopic end of the telescopic rod is rotatably connected to the other end of the swing arm.

[0008] Furthermore: The bottom outer wall of the offset ring is fixed with a motor, the output shaft of the motor is connected to a gear by a key, and the bottom outer wall of the turntable is provided with teeth, which mesh with the gear.

[0009] Based on the aforementioned scheme: the truncated cone mold assembly includes a truncated cone mold, a flange, and a second lifting cylinder. The flange is fixed to the outer wall of the truncated cone mold, and the second lifting cylinder is fixed to the top outer wall of the gantry frame by bolts. The telescopic end of the second lifting cylinder is fixed to the top outer wall of the flange by bolts.

[0010] A preferred embodiment of the aforementioned scheme is as follows: the inner wall of the truncated cone mold has multiple micro-air grooves that penetrate the inner wall in the height direction, the side wall of the truncated cone mold has air holes that communicate with the multiple micro-air grooves, and the inner wall of the flange has an air cavity that communicates with the multiple air holes simultaneously. The top outer wall of the flange is fixed with an air nozzle that communicates with the air cavity, and the air nozzle is connected to an air pump through an air pipe.

[0011] As a further aspect of the present invention: a piezoelectric ceramic excitation ring is fixed to the middle sidewall of the truncated cone mold, and the piezoelectric ceramic excitation ring is connected to an external power source.

[0012] Meanwhile, the eccentric drive mechanism includes a second motor, an eccentric cam, and an eccentric shaft. The eccentric shaft is rotatably connected to the inner side of the gantry frame. The eccentric cam is located at the eccentric part of the eccentric shaft. The second motor is fixed to the side wall of the gantry frame by bolts, and the output end of the second motor is fixed to the end of the eccentric shaft. A cam is fixed to the outer wall of the guide column. A spring is fastened to the top of the cam, and the other end of the spring is fastened to the bottom outer wall of the turntable.

[0013] As a preferred embodiment of the present invention, the eccentric cam is rotatably arranged relative to the eccentric part of the eccentric shaft, and their relative rotation can be locked.

[0014] Meanwhile, the bottom outer wall of the guide post is rotatably connected to a roller via a wheel axle, and the roller rolls against the outer wall of the eccentric cam.

[0015] As a preferred embodiment of the present invention: the outer walls on both sides of the guide column are fixed with a load-bearing frame by bolts, the top outer wall of the base is fixed with a lifting cylinder one by bolts, the telescopic end of the lifting cylinder one is fixed with an impact head two by bolts, the bottom of both ends of the lifting cylinder two are fixed with an impact head one by bolts, and the impact head one is located directly above the impact head two.

[0016] The beneficial effects of this invention are as follows: 1. The present invention, by setting a bearing plate assembly, which consists of an offset ring that can rotate vertically, a turntable that can rotate horizontally, and a bearing plate that can jump longitudinally, allows the finishing mortar to be subjected to a composite motion field of gravity component, centrifugal force, and flow shear force component, so as to obtain three-dimensional data of shear, inclination angle, and flowability, thereby better matching the actual working conditions and making the test results more accurate.

[0017] 2. The present invention, through the targeted design of the truncated cone mold, on the one hand, uses vibration to compact the finishing mortar, preventing air bubbles from forming inside the mortar and increasing the accuracy of subsequent testing; on the other hand, it adds micro-air grooves, air holes and air pumps, and the vibration of the truncated cone mold and the air film generated by the air pump can realize reliable separation of the mortar from the truncated cone mold, increasing the convenience of subsequent testing.

[0018] 3. Based on the eccentricity of the eccentric cam, this invention sets the eccentric cam and the eccentric shaft to rotate relative to each other, and the relative rotation can be locked. This makes the eccentricity of the eccentric shaft and the eccentric cam equal to the modulus of the sum of the eccentricity vector of the eccentric shaft and the eccentricity vector of the eccentric cam, thereby achieving the purpose of adjusting the impact force of the jumping table.

[0019] 4. In this invention, by setting up components such as lifting cylinder one, impact head two, and impact head one, the guide column and the bearing plate are first lifted upward a certain distance before the impact of the jumping table. Thus, when the bearing plate and the guide column descend rapidly and generate impact, the impact force is applied to the support frame, impact head one, and impact head two, and will not impact the eccentric cam and the turntable. The impact resistance of the support frame, impact head one, and impact head two is much higher than that of the slender eccentric shaft and the disc-shaped turntable, thereby preventing the device from deforming and improving its service life.

[0022] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0023] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] Example 1: A flowability testing device for decorative mortar production, such as... Figures 1-8 As shown, it includes a base 1, a gantry frame 3 is fixed to the top outer wall of the base 1 by bolts, a bearing plate assembly 4 is provided on the inner side of the middle part of the base 1, and a truncated cone mold assembly 5 is provided on the top of the bearing plate assembly 4 to cooperate with it.

[0025] The carrier disk assembly 4 includes: The offset ring 6 is rotatably connected to the inner side of the base 1 via the connecting shaft 11, and can be rotated along the axis of the connecting shaft 11 by a rotational driving torque; Turntable 7 is rotatably connected to the inner wall of offset ring 6 and can rotate along its own axis under rotational driving torque; The support plate 9 carries the finishing mortar and is slidably connected to the top of the turntable 7 via the guide post 8.

[0026] The top of the base 1 is also provided with an eccentric drive mechanism 2 that drives the guide column 8 to rise through eccentric motion.

[0027] The surface of the bearing plate 9 is provided with a cross scale 10, which can be used to assist in measuring the mortar flow.

[0028] When using this device, first place the truncated cone mold assembly 5 on the surface of the bearing plate 9, then fill the inner wall of the truncated cone mold assembly 5 with finishing mortar, then separate the truncated cone mold assembly 5, then the eccentric drive mechanism 2 can drive the guide column 8 to rise, and then the guide column 8 to fall, performing a "table-jumping impact". After the impact, the turntable 7 is driven by rotation, and then drives the bearing plate 9 to rotate through the guide column 8. At the same time, the connecting shaft 11 is driven by rotational torque to rotate a certain angle to simulate the elevation angle of the finishing. After maintaining this position for a certain period of time, all components stop and reset, and then the flow of mortar is measured.

[0029] This device, by setting up a support plate assembly 4, which consists of an offset ring 6 that can rotate vertically, a turntable 7 that can rotate horizontally, and a support plate 9 that can jump longitudinally, allows the finishing mortar to be subjected to a composite motion field of gravity, centrifugal force, and flow shear force components, so as to obtain three-dimensional data of shear, inclination angle, and flowability, thus better matching the actual working conditions and making the test results more accurate.

[0030] To solve the rotary drive problem; such as Figure 3 and Figure 4 As shown, a telescopic rod 13 is rotatably connected to one side wall of the gantry frame 3, and a swing arm 12 is fixed to the outer wall of the connecting shaft 11. The telescopic end of the telescopic rod 13 is rotatably connected to the other end of the swing arm 12.

[0031] When the telescopic rod 13 extends or retracts, it can drive the swing arm 12 to swing, thereby driving the connecting shaft 11 to rotate, and driving the entire bearing plate assembly 4 to rotate.

[0032] The bottom outer wall of the offset ring 6 is fixed with a motor 16 by a bracket. The output shaft of the motor 16 is connected to a gear 15 by a key. The bottom outer wall of the turntable 7 is provided with teeth 14, which mesh with the gear 15.

[0033] When the motor 16 starts, it can drive the gear 15 to rotate, thereby driving the turntable 7 to rotate through the meshing action of the gear 15 and the teeth 14.

[0034] To solve the demolding problem; such as Figure 5 As shown, the cone mold assembly 5 includes a cone mold 17, a flange 18, and a second lifting cylinder 34. The flange 18 is fixed to the outer wall of the cone mold 17, and the second lifting cylinder 34 is fixed to the top outer wall of the gantry frame 3 by bolts. The telescopic end of the second lifting cylinder 34 is fixed to the top outer wall of the flange 18 by bolts.

[0035] The inner wall of the truncated cone mold 17 has multiple micro-air grooves 19 that penetrate the inner wall in the height direction. The side wall of the truncated cone mold 17 has air holes 20 that communicate with the multiple micro-air grooves 19. The inner wall of the flange 18 has an air cavity that communicates with the multiple air holes 20. The top outer wall of the flange 18 is fixed with an air nozzle 22 that communicates with the air cavity. The air nozzle 22 is connected to an air pump through an air pipe.

[0036] A piezoelectric ceramic excitation ring 21 is fixed to the middle side wall of the truncated cone mold 17, and the piezoelectric ceramic excitation ring 21 is connected to an external power source.

[0037] After the finishing mortar is poured into the truncated cone mold 17, the piezoelectric ceramic excitation ring 21 is first vibrated by the high-frequency high-voltage voltage on the outer wall to compact the mortar. Then, the air pump passes air into the air nozzle 22 through the air pipe, and then the gas is introduced into the interface between the truncated cone mold 17 and the mortar through the air hole 20 and the micro air groove 19, so that an air film is formed between the interface of the mortar and the truncated cone mold 17. Then, the lifting cylinder 2 34 retracts to lift the truncated cone mold 17. After the truncated cone mold 17 is fully lifted, the external power supply of the air pump is turned off, so that the mortar is separated from the truncated cone mold 17.

[0038] This device, through targeted design of the truncated cone mold 17, serves two purposes. Firstly, the truncated cone mold 17 can use vibration to compact the finishing mortar, preventing air bubbles from forming inside the mortar and increasing the accuracy of subsequent testing. Secondly, the addition of micro-air grooves 19, air holes 20, and an air pump allows for reliable separation of the mortar from the truncated cone mold 17 by utilizing the vibration of the truncated cone mold 17 and the air film generated by the air pump, increasing the convenience of subsequent testing.

[0039] To solve the centrifugal drive problem; such as Figure 7 As shown, the eccentric drive mechanism 2 includes a second motor 26, an eccentric cam 27, and an eccentric shaft 28. The eccentric shaft 28 is rotatably connected to the inner side of the gantry frame 3. The eccentric cam 27 is located at the eccentric part of the eccentric shaft 28. The second motor 26 is fixed to the side wall of the gantry frame 3 by bolts, and the output end of the second motor 26 is fixed to the end of the eccentric shaft 28.

[0040] The eccentric cam 27 and the eccentric shaft 28 are rotatably arranged relative to each other at their eccentric points, and their relative rotation can be locked. Specifically, the eccentric cam 27 and the eccentric shaft 28 can be connected by a bearing, and then an expansion sleeve can be added. The expansion sleeve is inserted into the gap between the eccentric cam 27 and the eccentric shaft 28 and can be locked by interference fit. At the same time, screws can be added to fix the expansion sleeve to the eccentric cam 27 and / or the eccentric shaft 28.

[0041] The bottom outer wall of the guide post 8 is rotatably connected to a roller 29 via a wheel axle 25, and the roller 29 rolls against the outer wall of the eccentric cam 27.

[0042] A cam 30 is fixed to the outer wall of the guide post 8. A spring 23 is fastened to the top of the cam 30, and the other end of the spring 23 is fastened to the bottom outer wall of the turntable 7.

[0043] When the motor 26 starts, it drives the eccentric shaft 28 to rotate, which in turn drives the eccentric cam 27 to rotate. The eccentric cam 27 then applies a limiting force to the guide post 8, causing the guide post 8 to rise. The spring 23 is compressed and stores energy. Subsequently, after the roller 29 rolls away from the maximum outer diameter of the eccentric cam 27, the contact size between the eccentric cam 27 and the roller 29 decreases sharply. The guide post 8 rebounds rapidly due to the elastic force of the spring 23 and its own weight, achieving the purpose of "jumping table impact". At the same time, the overall eccentricity of the eccentric system of the eccentric shaft 28 and the eccentric cam 27 can be adjusted by rotating the eccentric cam 27.

[0044] This device, based on the eccentricity of the eccentric cam 27, sets the eccentric cam 27 and the eccentric shaft 28 to rotate relative to each other, and the relative rotation can be locked. This makes the eccentricity of the eccentric shaft 28 and the eccentric cam 27 equal to the modulus of the sum of the eccentric vector of the eccentric shaft 28 and the eccentric vector of the eccentric cam 27, thereby achieving the purpose of adjusting the impact force of the jumping table.

[0045] In this embodiment, during use, the extension of the second lifting cylinder 34 causes the truncated cone mold 17 to adhere to the surface of the bearing plate 9. Mortar is poured into the truncated cone mold 17. After the finishing mortar is poured into the truncated cone mold 17, the piezoelectric ceramic excitation ring 21 is first vibrated by the high-frequency high-voltage voltage on the outer wall to compact the mortar. Then, the air pump supplies air to the air nozzle 22 through the air pipe, and then introduces the gas into the interface between the truncated cone mold 17 and the mortar through the air hole 20 and the micro air groove 19, so that an air film is formed between the mortar interface and the truncated cone mold 17. Then, the second lifting cylinder 34 retracts, lifting the truncated cone mold 17. After the truncated cone mold 17 is fully lifted, the external power supply of the air pump is turned off, so that the mortar is separated from the truncated cone mold 17. When the second motor 26 is started, it can drive the eccentric shaft 28 to rotate, thereby driving the eccentric cam 27 to rotate. The eccentric cam 27 continues to exert a limiting force on the guide post 8, causing the guide post 8 to rise. The spring 23 is compressed and stores energy. Subsequently, after the roller 29 rolls away from the maximum outer diameter of the eccentric cam 27, the contact size between the eccentric cam 27 and the roller 29 decreases sharply. The guide post 8 rebounds rapidly under the elastic force of the spring 23 and its own weight, achieving the purpose of "jumping table impact". At the same time, when the telescopic rod 13 extends or retracts, it can drive the swing arm 12 to swing, thereby driving the connecting shaft 11 to rotate, driving the entire bearing plate assembly 4 to rotate. After rotating to the designed angle, it is fixed. When the motor 16 starts, it can drive the gear 15 to rotate, thereby driving the turntable 7 to rotate through the meshing action of the gear 15 and the teeth 14, causing the bearing plate 9 to rotate. After maintaining this for a certain period of time, all components stop and reset, and then the flow of mortar is measured.

[0046] Example 2: A flowability testing device for decorative mortar production, such as... Figure 8 As shown, in order to solve the lifespan problem, this embodiment makes the following improvements based on embodiment 1: the outer walls on both sides of the guide column 8 are fixed with a support frame 24 by bolts, the top outer wall of the base 1 is fixed with a lifting cylinder 33 by bolts, the telescopic end of the lifting cylinder 33 is fixed with an impact head 32 by bolts, the bottom of both ends of the lifting cylinder 34 is fixed with an impact head 31 by bolts, and the impact head 31 is located directly above the impact head 32.

[0047] In this embodiment, during the eccentric jumping table impact, the lifting cylinder 33 first extends, which drives the impact head 32 to rise until the impact head 32 contacts the impact head 31 and lifts the impact head 31 upwards by a distance of 1-2 cm, which is much smaller than the single stroke of the guide column 8. During this process, the bearing plate 9 does not contact the end face of the turntable 7. Subsequently, the eccentric system of the eccentric cam 27 and the eccentric shaft 28 drives the guide column 8 to rise, and the spring 23 is compressed. Then, when the guide column 8 descends rapidly, the impact head 31 will hit the impact head 32, and so on.

[0048] This device, by incorporating components such as lifting cylinder 33, impact head 32, and impact head 31, first lifts the guide column 8 and the bearing plate 9 upwards a certain distance before the impact of the jumping table. Thus, when the bearing plate 9 and guide column 8 rapidly descend and impact each other, the impact force is applied to the support frame 24, impact head 31, and impact head 32, and does not impact the eccentric cam 27 or the turntable 7. Furthermore, the impact resistance of the support frame 24, impact head 31, and impact head 32 is far greater than that of the slender eccentric shaft 28 and the disc-shaped turntable 7, thereby preventing device deformation and extending its service life.

[0049] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
