Description

Technical Field

[0001] This invention relates to the field of building construction equipment technology, specifically to an automatic proportioning and mixing system for dry-mixed mortar using a ground paving robot. Background Technology

[0002] In floor tile laying, the accuracy of the tile adhesive's mixing ratio, the uniformity of its mixing, and the continuity of its supply directly affect the laying quality and construction efficiency. In recent years, with the development of construction robot technology, floor laying robots have gradually replaced manual tile laying, placing higher demands on the supporting mortar mixing and supply system.

[0003] Most existing technologies rely on manual mixing of adhesives, with workers using experience to add, mix, and transport materials. There is no dedicated equipment, and the entire process depends on manual labor, with zero automation. Alternatively, semi-automatic independent mixing equipment can be used to mechanize the mixing process, but manual labor is still required for adding dry-mixed mortar, adding water for proportioning, and coordinating with robotic feeding, lacking collaborative operation capabilities. Large-scale automated mixing plants are also used, integrating automatic weighing, mixing, and conveying, achieving high proportioning accuracy. However, this is a fixed, centralized production method, and long-distance transport of finished mortar can lead to premature setting and performance degradation, failing to meet the flexible, small-batch feeding needs of on-site robots. The main drawbacks of existing technologies are poor proportioning accuracy, uncontrollable quality, insufficient automation, lack of a closed-loop operation, low feeding efficiency affecting continuous operation, poor adaptability to different scenarios, high labor intensity, and significant safety hazards.

[0004] Currently, some systems use paving robots with corresponding material feeding systems, employing sensors to sequentially weigh the dry-mixed mortar and water. However, in practical use, this system has the following shortcomings: vibration interference leads to decreased metering accuracy. When the motor starts for forced mixing, the high-frequency vibration generated by the rotating mixing blades impacting the material is directly transmitted to the weighing sensor, causing drastic fluctuations in the sensor's output signal. Furthermore, dynamic metering is difficult to achieve. Due to vibration interference, the system currently only uses a "batch static metering" mode—that is, stopping mixing and waiting for the vibration to decay before weighing and adding materials. This mode cannot monitor weight changes in real time during mixing, limiting continuous feeding efficiency and the flexibility of proportion adjustments. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic proportioning and mixing system for dry-mixed mortar using a robotic floor paving machine, in order to solve the problems of poor proportioning accuracy and inability to dynamically weigh in the existing technology.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automatic proportioning and mixing system for dry-mixed mortar used in floor paving is provided. The automatic proportioning and mixing system includes a frame, and a mixing mechanism is installed inside the frame. The mixing mechanism includes a mixing tank, a stirrer, a stirring motor, a weighing sensor, and a shock absorption assembly. The stirring motor output is equipped with a stirrer, which is placed inside the mixing tank. A shock absorption assembly is located below the mixing tank, and a weighing sensor is located below the shock absorption assembly. The damping assembly includes a transition plate, a spring, and a guide. The transition plate is equipped with a spring and a guide, with the spring positioned inside the guide. The guide component includes an upper sliding sleeve and a lower sliding sleeve, which are slidably connected. The bottom of the mixing tank is equipped with a spring and an upper sliding sleeve, the transition plate is equipped with a lower sliding sleeve, and the frame is equipped with a mixing motor and a weighing sensor.

[0007] The frame supports the entire automatic proportioning and mixing system. The mixing mechanism receives dry mortar and water, and quantitatively mixes the two to prepare a uniform tile adhesive. The mixing tank is a sealed cylindrical cavity with an internal agitator. The mixing motor is fixed to the frame and outputs torque to drive the agitator to rotate. The agitator achieves forced mixing of the dry mortar and water, producing a uniform tile adhesive. A weighing sensor detects the overall weight change of the mixing chamber in real time, providing feedback on the actual amount of dry mortar and water added, thus providing data support for accurate measurement. When the mixing motor drives the agitator to rotate and mix inside the mixing tank, the mixing tank itself... The mixing drum will generate continuous vibration. If the vibration is directly transmitted to the weighing sensor below, it will greatly interfere with the detection accuracy of the weighing sensor, resulting in a decrease in the accuracy of the mixing ratio. The vibration damping component can effectively reduce the vibration generated by the mixing. When the mixing drum is working, the vibration generated is first absorbed by the spring connected to the bottom. At the same time, the upper sliding sleeve will slide stably along the lower sliding sleeve. This ensures that the vertical movement of the mixing drum is not offset or blocked, and also prevents the vibration from being directly transmitted to the transition plate and the weighing sensor below. This allows the weighing sensor to always maintain a stable detection state, accurately control the amount of dry materials and water added, and ensure that the ratio meets the construction requirements.

[0008] Furthermore, the agitator includes a stirring screw, an edge spiral ribbon, and spokes. The stirring screw is provided at the output end of the stirring motor. The outer ring of the stirring screw is symmetrically provided with an edge spiral ribbon. The bottom of the stirring screw is provided with spokes. The stirring screw passes through the mixing tank.

[0009] During the mixing process, the mixing screw pushes and mixes the dry material and water in the middle of the mixing tank, while the dry mortar at the edge is tumbled by the symmetrically arranged edge ribbons to prevent the dry material from sticking to the inner wall of the mixing tank. The bottom area of ​​the mixing tank is continuously agitated by the stirrers to prevent the dry material from settling at the bottom and failing to mix fully. The combination of these three structures allows the various components of the dry-mixed mortar to be mixed more evenly, preventing uneven drying and wetting in some areas.

[0010] Furthermore, the machine frame is equipped with a dry material feeding mechanism, a water feeding mechanism, and a quantitative conveying mechanism; The mixing tank is equipped with a feed inlet and a water inlet, and a mixing outlet is located on one side of the mixing tank. The feed inlet is connected to the dry material feeding mechanism pipeline, the water inlet is connected to the water feeding mechanism pipeline, and the mixing outlet is connected to the quantitative conveying mechanism pipeline.

[0011] In actual operation, the dry material feeding mechanism feeds the set weight of dry mortar raw materials into the mixing tank through the feeding port according to the mixing ratio requirements. The water feeding mechanism adds the corresponding proportion of clean water at the same time and feeds it into the mixing tank through the water feeding port. After mixing, the mixed mortar is sent to the quantitative conveying mechanism through the mixing port. The quantitative conveying mechanism then directly transports the mixed mortar to the construction end of the paving robot. The whole process does not require manual weighing and mixing, and can achieve continuous automated operation.

[0012] Furthermore, the dry material feeding mechanism includes a dry material bin, a feeding screw, a feeding motor, and a dry material outlet pipe. The dry material bin and the feeding motor are located inside the frame. The feeding screw is located at the output end of the feeding motor and is placed inside the dry material bin. The lower end of the dry material bin is connected to the dry material outlet pipe, and one end of the dry material outlet pipe is inserted into the feeding port.

[0013] Dry materials are stored in the dry material hopper. When the feeding motor outputs torque to drive the feeding screw to rotate, it will stably push the dry materials from the dry material hopper to the dry material outlet pipe, and then send them into the mixing tank. With the real-time detection of the weighing sensor, when the set weight is reached, the feeding motor will stop running immediately, so as to accurately control the amount of dry materials added.

[0014] Furthermore, the dry material silo is arranged in an inverted cone shape, with a dry material inlet at the top and a dry material outlet at the bottom. One end of the feeding screw is inserted into the dry material outlet, and the dry material outlet is connected to the dry material outlet pipe.

[0015] The inverted cone-shaped hopper structure allows the dry material to gather at the bottom outlet under its own weight, preventing bridging and accumulation. This ensures a continuous and stable feeding process without interruption. Furthermore, when the feeding screw stops rotating, the dry material cannot fall because the screw is tightly fitted to the outlet, thus also functioning as a valve shut-off, eliminating the need for an additional outlet valve.

[0016] Furthermore, the water delivery mechanism includes a water storage tank, a water pump, and a water delivery pipe. The water storage tank is located inside the frame, and the water pump is located on the water storage tank. The water pump and the water delivery pipe are connected, and one end of the water delivery pipe is inserted into the water inlet.

[0017] The water storage tank is used to pre-store the clean water required for mixing mortar. When clean water needs to be added, the water pump starts and pumps the clean water in the storage tank directly into the water inlet of the mixing drum through the water delivery pipe. With the help of the weighing sensor, the overall weight change of the mixing drum is detected in real time. When the amount of clean water added reaches the preset ratio requirement, the water pump stops running immediately, so as to accurately control the amount of water added and ensure that the water-cement ratio meets the construction standards.

[0018] Furthermore, the water storage tank is equipped with an inlet and an outlet. The water pump is equipped with a suction pipe; Insert one end of the suction tube into the water outlet.

[0019] When the water pump is working, it draws water from the water storage tank through the suction pipe and then sends it into the mixing tank through the delivery pipe. With the help of the weight detection of the weighing sensor, the water pump stops working when the amount of water added reaches the required ratio, and the quantitative addition of water is completed automatically.

[0020] Furthermore, the quantitative conveying mechanism includes a mixing bin and a conveying pump, with the mixing bin and the conveying pump connected by pipelines, and one end of the conveying pump inserted into the mixing outlet.

[0021] The mixed mortar enters the conveying pump from the mixing outlet, and is then pumped into the mixing silo for temporary storage or directly delivered to the construction position of the paving robot, and the mixed mortar is output in a stable and quantitative manner according to the construction requirements.

[0022] Furthermore, the bottom of the frame is equipped with several casters, and a control panel is located on one side of the frame. The control panel is electrically connected to the mixing motor, weighing sensor, feeding motor, water pump, and conveying pump.

[0023] Workers can preset the ratio of dry materials and water through the control panel, monitor the operation status of the entire mixing process, automatically calculate the required weight of dry mortar and water, collect data from the weighing sensor in real time, control the start and stop of the feeding screw and water pump, achieve accurate measurement of dry materials and water, coordinate the linkage of the mixing motor and the conveying pump, display the equipment operation status and fault alarms, and the universal wheels at the bottom of the frame can facilitate the movement of the entire system with the paving robot, enabling the equipment to move flexibly on the construction site and adapt to the operation needs of different construction areas.

[0024] Compared with the prior art, the beneficial effects of the present invention are: 1. The present invention achieves vibration isolation between the mixing tank and the frame through the shock absorption component, while ensuring the accurate transmission of static gravity signal. The weighing sensor reading is stable during the mixing process, improving the metering accuracy and the water-cement ratio control accuracy. This ensures the bonding strength of the tile adhesive from the source and effectively avoids the problems of tile hollowing and falling off.

[0025] 2. This invention isolates vibration through shock-absorbing components. The system can monitor weight changes in real time and stably during the mixing process, and supports dynamic control modes such as "adding water while mixing" or "measuring while conveying", realizing dynamic continuous metering and improving continuous feeding efficiency.

[0026] 3. This invention directly measures the weight of dry-mixed mortar and water by using a weight sensor, replacing the traditional decentralized metering method. This avoids errors in dry material metering and deviations in water level detection, resulting in high accuracy in water-cement ratio control and uniform and stable tile adhesive bonding strength, thus solving the quality problems of tile hollowing and falling off.

[0029] 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.

[0030] Example: Figures 1-6 As shown, the present invention provides a technical solution: an automatic proportioning and mixing system for dry-mixed mortar for ground paving robots.

[0031] like Figures 1-4 As shown, a dry mortar automatic proportioning and mixing system for floor paving robots is provided. The automatic proportioning and mixing system includes a frame 5, and a mixing mechanism 3 is provided inside the frame 5. The stirring mechanism 3 includes a stirring tank 31, a stirrer 32, a stirring motor 33, a weighing sensor 34, and a shock absorption component 35. The stirring motor 33 has a stirrer 32 at its output end, which is placed inside the stirring tank 31. The shock absorption component 35 is located below the stirring tank 31, and the weighing sensor 34 is located below the shock absorption component 35. The shock absorption assembly 35 includes a transition plate 351, a spring 352 and a guide 353. The transition plate 351 is provided with a spring 352 and a guide 353, and the spring 352 is placed in the inner ring of the guide 353. Guide component 353 includes an upper sliding sleeve 3531 and a lower sliding sleeve 3532, which are slidably connected. The bottom of the mixing tank 31 is provided with a spring 352 and an upper sliding sleeve 3531, and the transition plate 351 is provided with a lower sliding sleeve 3532. The frame 5 is provided with a mixing motor 33 and a weighing sensor 34.

[0032] The frame 5 supports the entire automatic proportioning and mixing system. The mixing mechanism 3 receives dry mortar and water, and quantitatively mixes the two to prepare uniform tile adhesive. The mixing tank 31 is a sealed cylindrical cavity with a built-in agitator 32. The mixing motor 33 is fixed on the frame 5 and outputs torque to drive the agitator 32 to rotate. The agitator 32 achieves forced mixing of dry mortar and water to produce uniform tile adhesive. The weighing sensor 34 is used to detect the overall weight change of the mixing chamber in real time, and provides feedback on the actual amount of dry mortar and water added, providing data support for accurate measurement. When the mixing motor 33 drives the agitator 32 to rotate and mix inside the mixing tank 31, the mixing tank 31 itself will generate... The continuous vibration generated by the mixing drum 31, if directly transmitted to the weighing sensor 34 below, would significantly interfere with the detection accuracy of the weighing sensor 34, leading to a decrease in the mixing ratio accuracy. The vibration damping component 35 can effectively reduce the vibration generated by the mixing. When the mixing drum 31 is working, the vibration generated is first absorbed by the spring 352 connected to the bottom, and at the same time, the upper sliding sleeve 3531 will slide stably along the lower sliding sleeve 3532. This ensures that the vertical movement of the mixing drum 31 is not offset or blocked, and also prevents the vibration from being directly transmitted to the transition plate 351 and the weighing sensor 34 below. This allows the weighing sensor 34 to always maintain a stable detection state, accurately control the amount of dry materials and water added, and ensure that the mixing ratio meets the construction requirements.

[0033] like Figure 3 As shown, the stirrer 32 includes a stirring screw 321, an edge spiral ribbon 322, and a spoke 323. The stirring screw 321 is provided at the output end of the stirring motor 33. The edge spiral ribbon 322 is symmetrically provided on the outer ring of the stirring screw 321. The spoke 323 is provided at the bottom of the stirring screw 321. The stirring screw 321 passes through the stirring tank 31.

[0034] During the mixing process, the mixing screw 321 pushes and mixes the dry material and water in the middle of the mixing tank 31, while the dry mortar at the edge is tumbled by the symmetrically arranged edge ribbons 322 to prevent the dry material from sticking to the inner wall of the mixing tank 31. The bottom area of ​​the mixing tank 31 is continuously stirred by the spokes 323 to prevent the dry material from settling at the bottom of the tank and failing to mix fully. The combination of the three structures allows the various components of the dry mortar to be mixed more evenly, and there will be no uneven drying of the mortar in some areas.

[0035] like Figures 1-3 As shown, the frame 5 is equipped with a dry material feeding mechanism 1, a water feeding mechanism 2, and a quantitative conveying mechanism 4. The mixing tank 31 is provided with a feeding port 311 and a water inlet 312, and a mixing outlet 313 is provided on one side of the mixing tank 31. The feed port 311 is connected to the dry material feeding mechanism 1 via a pipeline, the water inlet 312 is connected to the water feeding mechanism 2 via a pipeline, and the mixing outlet 313 is connected to the quantitative conveying mechanism 4 via a pipeline.

[0036] In actual operation, the dry material feeding mechanism 1 feeds the set weight of dry mortar raw materials into the mixing tank 31 through the feeding port 311 according to the mixing ratio requirements. The water feeding mechanism 2 adds the corresponding proportion of clean water at the same time and feeds it into the mixing tank 31 through the water feeding port 312. After mixing, the mixed mortar is fed into the quantitative conveying mechanism 4 through the mixing port 313. The quantitative conveying mechanism 4 then directly conveys the mixed mortar to the construction end of the paving robot. The whole process does not require manual weighing and mixing, and can achieve continuous automated operation.

[0037] like Figure 5 As shown, the dry material feeding mechanism 1 includes a dry material bin 11, a feeding screw 12, a feeding motor 13, and a dry material outlet pipe 14. The dry material bin 11 and the feeding motor 13 are located inside the frame 5. The feeding screw 12 is located at the output end of the feeding motor 13. The feeding screw 12 is placed inside the dry material bin 11. The lower end of the dry material bin 11 is connected to the dry material outlet pipe 14. One end of the dry material outlet pipe 14 is inserted into the feeding port 311.

[0038] The dry material is stored in the dry material hopper 11. When the feeding motor 13 outputs torque to drive the feeding screw 12 to rotate, it will stably push the dry material from the dry material hopper 11 to the dry material outlet pipe 14, and then send it into the mixing tank 31. With the real-time detection of the weighing sensor 34, when the set weight is reached, the feeding motor 13 will stop running immediately, so as to accurately control the amount of dry material added.

[0039] like Figure 5 As shown, the dry material bin 11 is arranged in an inverted cone shape. The top of the dry material bin 11 is provided with a dry material inlet 111, and the bottom of the dry material bin 11 is provided with a dry material outlet 112. One end of the feeding screw 12 is inserted into the dry material outlet 112, and the dry material outlet 112 is connected to the dry material outlet pipe 14.

[0040] The inverted cone-shaped hopper structure allows the dry material to gather at the bottom dry material outlet 112 under its own weight, preventing bridging and accumulation of dry material. This ensures a continuous and stable feeding process without interruption. Furthermore, when the feeding screw 12 stops rotating, the dry material cannot fall because the feeding screw 12 is tightly fitted with the dry material outlet 112, thus also serving as a valve shut-off function, eliminating the need for an additional discharge valve.

[0041] like Figure 6 As shown, the water delivery mechanism 2 includes a water storage tank 21, a water pump 22 and a water delivery pipe 23. The water storage tank 21 is located inside the frame 5, and the water pump 22 is located on the water storage tank 21. The water pump 22 and the water delivery pipe 23 are connected. One end of the water delivery pipe 23 is inserted into the water inlet 312.

[0042] The water storage tank 21 is used to pre-store the clean water required for mixing mortar. When clean water needs to be added, the water pump 22 is started, and the clean water in the water storage tank 21 is directly pumped into the water inlet 312 of the mixing tank 31 through the water delivery pipe 23. With the help of the weighing sensor 34, the overall weight change of the mixing tank 31 is detected in real time. When the amount of clean water added reaches the preset ratio requirement, the water pump 22 immediately stops running, so as to accurately control the amount of water added and ensure that the water-cement ratio meets the construction standards.

[0043] like Figure 6 As shown, the water storage tank 21 is provided with an inlet 211 and an outlet 212 respectively; The water pump 22 is equipped with a suction pipe 221; One end of the suction pipe 221 is inserted into the outlet 212.

[0044] When the water pump 22 is working, it draws water from the water storage tank 21 through the suction pipe 221 and then sends it into the mixing tank 31 through the water delivery pipe 23. With the weight detection of the weighing sensor 34, the water pump 22 stops working when the amount of water added reaches the required ratio, and automatically completes the quantitative addition of water.

[0045] like Figures 2-3As shown, the quantitative conveying mechanism 4 includes a mixing bin 41 and a conveying pump 42. The mixing bin 41 and the conveying pump 42 are connected by pipelines, and one end of the conveying pump 42 is inserted into the mixing port 313.

[0046] The mixed mortar enters the conveying pump 42 from the mixing outlet 313, and is then pumped into the mixing silo 41 for temporary storage or directly delivered to the construction position of the paving robot, and the mixed mortar is output stably and quantitatively according to the construction requirements.

[0047] like Figure 1 As shown, the bottom of the frame 5 is equipped with several casters 6, and a control panel 7 is provided on one side of the frame 5. The control panel 7 is electrically connected to the stirring motor 33, the weighing sensor 34, the feeding motor 13, the water pump 22 and the conveying pump 42 respectively.

[0048] Workers can preset the ratio parameters of dry materials and water through the control panel 7, monitor the operation status of the entire mixing process, automatically calculate the required weight of dry mortar and water, collect data from the weighing sensor 34 in real time, control the start and stop of the feeding screw 12 and water pump 22 to achieve accurate measurement of dry materials and water, coordinate the linkage of the mixing motor 33 and the conveying pump 42, display the equipment operation status and fault alarms, and the universal wheels 6 at the bottom of the frame 5 can facilitate the movement of the entire system with the paving robot, realize the flexible movement of the equipment on the construction site, and adapt to the operation needs of different construction areas.

[0049] Working principle of the invention: The control panel 7 calculates the required weight of dry-mixed mortar and water based on the input target water-cement ratio and the total weight of tile adhesive. The feeding screw 12 is started to deliver the dry-mixed mortar to the mixing tank 31, and the weighing sensor 34 monitors the weight increment in real time. Feeding stops when the dry material set value is reached. Simultaneously, the water pump 22 is started to add water to the mixing tank 31, and the weighing sensor 34 continues to monitor the weight increment. Water addition stops when the added water reaches the calculated value. During the feeding process, the mixing motor 33 is started for forced mixing. During this process, the vibration generated by the rotation of the mixer 32 is absorbed by the spring 352 in the shock absorption assembly 35, preventing high-frequency vibration from being transmitted to the weighing sensor 34, thus improving weighing accuracy. Simultaneously, due to the constraint of the guide component 353, the transition plate 351 only moves slowly up and down with the static weight changes of the mixing tank 31 and the material. The signal output by the weighing sensor 34 is stable and without fluctuations, allowing for real-time and accurate reading of the total weight during mixing. After mixing is completed, the delivery pump 42 is started to deliver the tile adhesive to the floor tiling robot.

[0050] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
