Description

Technical Field

[0001] This invention relates to the field of cement adhesive mixing technology, specifically to a cement adhesive mixing device with precise proportioning function. Background Technology

[0002] Cement adhesive is typically formed by mixing cement, water, adhesive liquid, and a certain proportion of additives. It is widely used in building construction, wall and floor leveling, waterproofing, repair and reinforcement, and other applications. The performance of cement adhesive is closely related to the accuracy of the proportions of its raw materials. If the ratio of cement, water, and adhesive liquid is not accurately controlled, it can easily lead to unstable consistency, insufficient bonding strength, abnormal setting time, or poor workability, thus affecting the quality of subsequent construction.

[0003] Existing cementitious adhesive mixing methods often involve manual weighing, manual addition of water, and manual pouring of materials before mixing by a mixer, or simply using ordinary mixing buckets and paddles to simply stir the raw materials. While these methods can complete the basic preparation of cementitious adhesive, in actual use, the amount of powder and liquid added usually depends on the operator's experience and judgment, making it difficult to ensure that the proportions are consistent each time.

[0004] Existing cement adhesive mixing devices typically add cement powder, water, adhesive liquid, and additives directly into a mixing tank or mixing vessel, and then mix them using mixing blades. The materials are mostly weighed and poured manually, or the amount of material is controlled by the opening time of the solenoid valve and the running time of the feeding motor. It is impossible to confirm the actual weight of each material before it enters the mixing vessel. If too much or too little material is poured in, it is difficult to correct it individually afterward, which can easily lead to inaccurate proportions of the entire batch of cement adhesive. Summary of the Invention

[0005] The purpose of this invention is to provide a cement paste mixing device with precise proportioning function to solve the problems mentioned in the background art.

[0006] The main technical problem solved by this invention is:

[0007] The existing materials mostly rely on manual weighing and manual pouring, or the amount of material fed is controlled by the opening time of the solenoid valve and the running time of the feeding motor. It is impossible to confirm the actual weight of each material before it enters the mixing tank, which can easily lead to inaccurate cement adhesive ratios for the entire batch.

[0008] This invention can be achieved through the following technical solutions:

[0009] A cement adhesive mixing device with precise proportioning function includes a base, a fixed seat embedded in the upper surface of the base, a mixing tank snapped into the fixed seat, a batching box in the upper part of the inner cavity of the mixing tank, and a slot in the middle of the top surface of the mixing tank. A mixing unit that can smoothly pass through the slot is raised and lowered directly above the mixing tank. The top surface of the mixing tank is provided with multiple batching hoppers for storing cement adhesive materials. The batching box has a proportioning bin that communicates with the corresponding batching hopper. The proportioning bin does not communicate with the slot. Each proportioning bin has a weighing and metering dispensing unit inside.

[0010] The weighing and metering unloading unit includes two electric grippers, one above the other, and a weighing component is installed between the two electric grippers. A rotating shaft driven by a built-in servo motor is installed between the outer wall of the weighing component and the inner wall of the corresponding side proportioning bin.

[0011] Each of the batching hoppers is equipped with a telescopic docking unit on its lower end face that is sealed and fitted to the corresponding weighing component.

[0012] A further technical improvement of the present invention is that: the weighing component includes a tilting cylinder, a weighing sensor is embedded in the bottom surface of the inner cavity of the tilting cylinder, and a weighing hopper that contacts the weighing sensor is installed inside the tilting cylinder. The rear side of the tilting cylinder is fixed to the end of the rotating shaft, and the front side of the tilting cylinder is rotatably connected to the proportioning bin. The upper end of the weighing hopper communicates with the opening at the top of the tilting cylinder.

[0013] A further technical improvement of the present invention is that the telescopic docking unit includes an electric cylinder installed on the lower part of the batching hopper, and the pushing end of the electric cylinder is connected to a corrugated clamp tube that seals and presses the top opening of the tilting cylinder.

[0014] A further technical improvement of the present invention is that: a spiral feeding shaft driven by a feeding motor on the bottom surface is installed at the bottom of the inner cavity of a batching hopper to convey cement powder;

[0015] The bottom of the discharge hoppers of the other batching hoppers are all equipped with solenoid valves.

[0016] A further technical improvement of the present invention is that: the stirring unit includes a stirrer disposed above the mixing tank, the stirrer being configured with a cross-shaped structure;

[0017] The mixing unit also includes a support frame located at the rear of the mixing tank. A lifting plate is slidably mounted on the support frame. The agitator is rotatably mounted on the lower surface of the lifting plate. The surface of the lifting plate is provided with multiple feed ports that are inserted and matched with corresponding batching hoppers.

[0018] A further technical improvement of the present invention is that: a support plate is installed on one side of the mixing tank, a bearing seat is installed on the top side of the support plate, a support frame is installed at both ends of the lower end face of the bearing seat, and a cleaning component that slides to the bottom of the agitator is installed on the upper surface of the support frame;

[0019] The gap between the two support frames is longer than the diameter of the mixing tank.

[0020] A further technical improvement of the present invention is that: the cleaning component includes a movable platform slidably connected to a support frame, a fixed frame is mounted on the upper surface of the movable platform, and a cleaning tank is installed inside the fixed frame, the diameter of the cleaning tank being larger than the size of the agitator;

[0021] A hydraulic cylinder is installed on the outer side of the support plate to push the moving platform to slide, and a limiting rod that penetrates the inside of the bearing seat is installed on one side of the moving platform.

[0022] A further technical improvement of the present invention is that: three support legs are installed on the lower end face of the mixing tank, each support leg is in contact with the inner wall of the fixed seat, and an electromagnetic push rod is installed on the inner side of each support leg; a positioning block pushed by the corresponding electromagnetic push rod is provided in the through groove of the support leg.

[0023] The inner wall of the fixed base is provided with a positioning groove that is inserted and matched with the corresponding positioning block. The positioning groove is a trapezoidal groove that is wider on the outside and narrower on the inside.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. By setting up a weighing unit, multiple batching bins complete docking, weighing, flipping, and discharging actions in the batching bin sequentially or synchronously according to a preset ratio. This allows materials such as cement powder, water, adhesive, and additives to be independently weighed before entering the mixing tank, reducing the proportioning error caused by changes in the fluidity of cement powder, changes in the viscosity of adhesive, or fluctuations in liquid pressure. When the detected weight reaches the preset weight range, the control unit stops the corresponding batching bin from continuing to discharge, thus completing the quantitative weighing of the material. The telescopic docking unit retracts to make room for the flipping cylinder to flip. The electric gripper releases the clamping limit on the weighing unit, and the flipping cylinder flips under the drive of the rotating shaft, causing the weighed material in the weighing hopper to be poured into the mixing tank, shortening the feeding time, reducing the retention of material in the weighing hopper, and improving continuous batching.

[0026] 2. By setting up a movable cleaning component, during mixing, the cleaning box is located on one side of the mixing tank, which does not affect the agitator's descent into the mixing tank; during cleaning, the cleaning box slides to directly below the agitator, making the mixing and cleaning processes independent of each other. This avoids the cleaning box occupying the space above the mixing tank for a long time. Since the cleaning box is moved directly below the agitator, the agitator can be cleaned in the cleaning box without disassembly, reducing manual disassembly and cleaning steps, reducing operational intensity, and reducing the adhesion and hardening of residual cement adhesive on the agitator.

[0027] 3. By pushing the corresponding positioning block outward along the through groove of the support leg by the electromagnetic push rod, the positioning block is inserted into the positioning groove on the inner wall of the fixed seat, so that the mixing tank completes circumferential limiting and radial positioning in the fixed seat. The mixing tank maintains a stable and centered state in the fixed seat, thereby ensuring that the central axis of the mixing tank and the rotation axis of the agitator are on the same vertical line. When the agitator descends, it accurately passes through the slot and enters the interior of the mixing tank, avoiding collision between the agitator and the edge of the slot or the inner wall of the mixing tank due to the displacement of the mixing tank.

[0036] To further illustrate the technical means and effects of the present invention in achieving the intended purpose, the following detailed description of the specific implementation methods, structures, features and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided.

[0037] Please see Figures 1-6 As shown, the present invention provides a cement adhesive mixing device with precise proportioning function, including a base 14, a fixed seat 1 embedded in the upper surface of the base 14, a mixing tank 3 snapped into the inside of the fixed seat 1, a batching box provided in the upper part of the inner cavity of the mixing tank 3, and a slot 7 provided in the middle of the top surface of the mixing tank 3. A mixing unit that can smoothly pass through the inside of the slot 7 is provided on the top of the mixing tank 3. Multiple batching hoppers 6 for storing cement adhesive materials are provided on the top surface of the mixing tank 3. The inside of the batching box is provided with a proportioning bin 26 that communicates with the corresponding batching bin 6. The proportioning bin 26 does not communicate with the slot 7. Each proportioning bin 26 is provided with a weighing and metering dispensing unit inside.

[0038] The weighing and metering unloading unit includes two electric grippers 21, one above the other, and a weighing component is installed between the two electric grippers 21. A rotating shaft 24 driven by a built-in servo motor is installed between the outer wall of the weighing component and the inner wall of the corresponding side proportioning bin 26.

[0039] Each batching hopper 6 has a telescopic docking unit installed on its lower end face that is sealed and fits tightly with the corresponding weighing component.

[0040] The weighing device includes a tilting cylinder 22, a weighing sensor 25 is embedded in the bottom surface of the inner cavity of the tilting cylinder 22, and a weighing hopper 23 that contacts the weighing sensor 25 is installed inside the tilting cylinder 22. The rear side of the tilting cylinder 22 is fixed to the end of the rotating shaft 24, and the front side of the tilting cylinder 22 is rotatably connected to the proportioning bin 26. The upper end of the weighing hopper 23 communicates with the opening at the top of the tilting cylinder 22.

[0041] When in use, first snap the mixing tank 3 into the fixed seat 1 on the upper surface of the base 14 so that the mixing tank 3 is stably positioned on the base 14. Different batching hoppers 6 are used to store cement powder, water, adhesive liquid or additives and other cement adhesive raw materials.

[0042] During batching, the telescopic docking unit on the lower end face of the batching hopper 6 extends first and seals against the corresponding weighing component, allowing the material in the batching hopper 6 to enter the weighing hopper 23 along the sealed channel. Because the telescopic docking unit and the weighing component are sealed together, the material is less likely to leak from the connection point during its descent. After the material enters the weighing hopper 23, the weighing hopper 23 transfers the material's weight to the weighing sensor 25 located below it. The weighing sensor 25 detects the weight of the material in the weighing hopper 23 in real time and feeds the detection signal back to the control unit. When the detected weight is lower than the preset weight, the control unit continues to control the corresponding batching hopper 6 to feed material; when the detected weight reaches the preset weight range, the control unit stops the corresponding batching hopper 6 from feeding material, thus completing the quantitative weighing of the material.

[0043] During the weighing process, the tilting cylinder 22 is positioned between the upper and lower electric grippers 21. The electric grippers 21 can clamp and limit the tilting cylinder 22 or the weighing component, ensuring that the weighing hopper 23 maintains a stable posture when receiving and weighing materials, reducing shaking caused by material impact, and improving the detection stability of the weighing sensor 25. Once the material in the weighing hopper 23 reaches the set weight, the telescopic docking unit retracts, releasing the sealed connection between it and the tilting cylinder 22, leaving space for the subsequent tilting of the tilting cylinder 22.

[0044] Subsequently, the electric gripper 21 releases its gripping limit on the weighing component, and the built-in servo motor drives the rotating shaft 24 to rotate. Since the rear side of the tilting cylinder 22 is fixedly connected to the rotating shaft 24, the tilting cylinder 22 tilts under the influence of the rotating shaft 24. The weighing hopper 23 inside the tilting cylinder 22 tilts accordingly, causing the weighed material in the weighing hopper 23 to pour into the mixing tank 3. After the tilting is complete, the servo motor drives the rotating shaft 24 in the opposite direction, returning the tilting cylinder 22 and the weighing hopper 23 to the receiving state. The electric gripper 21 then grips and limits the material again, awaiting the next weighing and dispensing cycle.

[0045] After the tilting drum 22 is reset, the control unit detects the weight of the empty hopper 23 according to the weighing sensor 25 and performs tare correction. When the weight of the empty hopper exceeds the preset residual threshold, the control unit issues a cleaning prompt or controls the weighing hopper 23 to tilt and shake the material again to reduce the impact of the residue on subsequent weighing.

[0046] Multiple batching hoppers 6 sequentially or simultaneously perform docking, weighing, tilting, and discharging actions according to a preset ratio. This ensures that cement powder, water, adhesive, and admixtures are independently metered before entering the mixing tank 3, reducing proportioning errors caused by changes in cement powder flowability, adhesive viscosity, or liquid pressure fluctuations. After each material falls into the mixing tank 3, the lifting and lowering stirring unit descends and passes through the slot 7 into the mixing tank 3 to stir and mix the materials inside. After stirring is complete, the stirring unit rises and exits the mixing tank 3, and the resulting cement adhesive can be discharged through the discharge structure of the mixing tank 3.

[0047] See Figure 6 As shown, the telescopic docking unit includes an electric cylinder 19 installed on the lower part of the batching hopper 6, and the pushing end of the electric cylinder 19 is connected to a corrugated clamp tube 20 that seals and presses against the top opening of the tilting cylinder 22.

[0048] Before batching, the tilting drum 22 is in the receiving state. The electric cylinder 19 is started and pushes the corrugated clamp 20 downward until the lower end of the corrugated clamp 20 is pressed against the top opening of the tilting drum 22. This forms a relatively sealed feeding channel between the discharge end of the batching hopper 6, the corrugated clamp 20, and the top opening of the tilting drum 22, reducing the amount of powder that flies out from the gap between the batching hopper 6 and the tilting drum 22, and also reducing the problem of liquid material splashing or leaking.

[0049] Since the material enters the metering hopper 23 through the corrugated tube 20, it is less likely to scatter onto the outside of the tilting drum 22 or the inner wall of the proportioning bin 26, which can reduce material loss and make the weight detected by the weighing sensor 25 closer to the actual weight of the material entering the metering hopper 23, thereby improving the proportioning accuracy.

[0050] See Figure 5 As shown, a screw feeder shaft driven by a feeding motor on the bottom surface is installed at the bottom of the inner cavity of a batching hopper 6 to convey cement powder.

[0051] The bottom of the discharge hoppers 6 are all equipped with solenoid valves.

[0052] Because cement bridging can easily form at the bottom of the batching hopper 6, when batching cement powder, a feeding motor drives the screw feeder shaft to rotate, disturbing the cement powder and preventing blockage at the bottom of the hopper. This allows the cement powder to enter the metering hopper 23 through the corrugated tube 20. When batching liquid materials, the control unit controls the solenoid valve to open, allowing the liquid material to enter the metering hopper 23 through the corrugated tube 20. The weighing sensor 25 monitors the weight of the material in the metering hopper 23 in real time. When the detected weight reaches the corresponding preset weight range, the control unit shuts off the feeding motor or solenoid valve and controls the electric cylinder 19 to retract the corrugated tube 20. Subsequently, the tilting cylinder 22 tilts, pouring the weighed material in the metering hopper 23 into the mixing tank 3.

[0053] See Figure 2 As shown, the stirring unit includes a stirrer 5 located above the mixing tank 3, and the stirrer 5 is configured with a cross-shaped structure.

[0054] The mixing unit also includes a support frame located at the rear of the mixing tank 3. A lifting plate 2 is slidably installed on the support frame. The agitator 5 is rotatably installed on the lower surface of the lifting plate 2. The surface of the lifting plate 2 is provided with multiple feed ports 4 that are inserted and matched with the corresponding batching hoppers 6.

[0055] When stirring is required, the lifting plate 2 moves downward along the support frame, causing the agitator 5 to descend smoothly, allowing the agitator 5 to pass smoothly through the slot 7 in the middle of the top surface of the mixing tank 3 and enter the interior of the mixing tank 3. Since the lifting plate 2 is provided with a feed inlet 4 corresponding to the batching hopper 6, the batching hopper 6 can be inserted into the feed inlet 4 when the lifting plate 2 descends, avoiding interference between the lifting plate 2 and the batching hopper 6, and also playing an auxiliary role in positioning the descending position of the lifting plate 2.

[0056] After the materials in each batching hopper 6 are accurately dropped into the mixing tank 3 by the weighing and metering unit, the agitator 5 starts to rotate, so that the cement powder, water, adhesive and admixtures are fully mixed in the mixing tank 3, reducing local clumping or uneven mixing.

[0057] See Figure 1 and Figure 3 As shown, a support plate is installed on one side of the mixing tank 3, a bearing seat 9 is installed on the top side of the support plate, support frames 8 are installed at both ends of the lower end face of the bearing seat 9, and a cleaning component that slides to the bottom of the agitator 5 is installed on the upper surface of the support frame 8.

[0058] The gap length between the two support frames 8 is greater than the diameter of the mixing tank 3.

[0059] The cleaning component includes a movable table 13 that is slidably connected to the support frame 8. A fixed frame 12 is mounted on the upper surface of the movable table 13. A cleaning tank 11 is installed inside the fixed frame 12. The diameter of the cleaning tank 11 is larger than the size of the agitator 5.

[0060] A hydraulic cylinder 10 is installed on the outside of the support plate to push the moving platform 13 to slide, and a limiting rod that penetrates the inside of the bearing seat 9 is installed on one side of the moving platform 13.

[0061] During mixing, the oil cylinder 10 is in a retracted state, and the moving platform 13 moves the fixed frame 12 and the cleaning box 11 to one side of the mixing tank 3, so that the cleaning box 11 avoids the working area of ​​the agitator 5 and the mixing tank 3. The lifting plate 2 drives the agitator 5 to descend, and the agitator 5 passes through the slot 7 and enters the mixing tank 3 to mix the cement powder, water, adhesive and additives.

[0062] After mixing is complete, the lifting plate 2 lifts the agitator 5, causing it to exit the mixing tank 3. At this time, the hydraulic cylinder 10 starts and pushes the moving platform 13 to slide along the support frame 8. The moving platform 13 moves the fixed frame 12 and the cleaning tank 11 to directly below the agitator 5. Since the diameter of the cleaning tank 11 is larger than the size of the agitator 5, the agitator 5 smoothly enters the cleaning tank 11.

[0063] Subsequently, the lifting plate 2 lowers the agitator 5, allowing it to extend into the cleaning tank 11. The cleaning tank 11 is pre-filled with cleaning fluid or connected to an external water supply line. After the agitator 5 enters the cleaning tank 11, it rotates at low speed, causing any residual cement adhesive on its surface to be washed away, soaked, or shaken off by the cleaning fluid, thus completing the cleaning of the agitator 5. After cleaning, the lifting plate 2 raises the agitator 5, the hydraulic cylinder 10 retracts, and the cleaning tank 11 returns to its original position on one side of the mixing tank 3, ready for the next cleaning cycle.

[0064] See Figure 1 and Figure 4 As shown, three support legs 16 are installed on the lower end face of the mixing tank 3. Each support leg 16 is in contact with the inner wall of the fixed base 1, and an electromagnetic push rod 17 is installed on the inner side of each support leg 16. A positioning block 18 is provided in the through groove of the support leg 16 and is pushed by the corresponding electromagnetic push rod 17.

[0065] The inner wall of the fixed base 1 is provided with a positioning groove 15 that is inserted and matched with the corresponding positioning block 18. The positioning groove 15 is a trapezoidal groove that is wider on the outside and narrower on the inside.

[0066] The mixing tank 3 is placed inside the fixed base 1. The three support legs 16 at the bottom of the mixing tank 3 are respectively attached to the inner wall of the fixed base 1, so that the mixing tank 3 forms a three-point support in the fixed base 1. Then, the electromagnetic push rod 17 is activated, pushing the corresponding positioning block 18 to slide outward along the through groove of the support leg 16, so that the positioning block 18 is inserted into the positioning groove 15 on the inner wall of the fixed base 1. When the positioning block 18 is inserted, it can first pass through the wider groove and smoothly enter the positioning groove 15, and then gradually be guided and wedged along the inclined surfaces on both sides of the positioning groove 15, so that a stable limit is formed between the support leg 16 and the fixed base 1, so that the mixing tank 3 completes the circumferential limit and radial positioning in the fixed base 1. The mixing tank 3 maintains a stable and centered state in the fixed base 1, thereby ensuring that the central axis of the mixing tank 3 and the rotation axis of the stirrer 5 are on the same vertical line.

[0067] When the lifting plate 2 drives the agitator 5 to descend, the agitator 5 can accurately pass through the slot 7 and enter the mixing tank 3, avoiding collisions between the agitator 5 and the edge of the slot 7 or the inner wall of the mixing tank 3 due to the offset of the mixing tank 3. At the same time, it can also reduce the problems of uneven mixing, increased vibration and equipment wear caused by eccentric mixing, and improve the stability of the mixing process and the uniformity of cement adhesive mixing.

[0068] In use, this invention, by setting up a weighing unit, allows multiple batching hoppers 6 to complete docking, weighing, flipping, and discharging actions in the mixing bin 26 sequentially or simultaneously according to a preset ratio. This ensures that materials such as cement powder, water, adhesive, and additives can be independently weighed before entering the mixing tank 3, reducing the proportioning error caused by changes in the fluidity of cement powder, changes in the viscosity of adhesive, or fluctuations in liquid pressure. When the detected weight reaches the preset weight range, the control unit stops the corresponding batching hopper 6 from continuing to discharge, thereby completing the quantitative weighing of the material. The telescopic docking unit retracts, leaving space for the flipping cylinder 22 to flip. The electric gripper 21 releases the clamping limit on the weighing unit, and the flipping cylinder 22 flips under the drive of the rotating shaft 24, causing the material that has been weighed in the weighing hopper 23 to be poured into the mixing tank 3, shortening the feeding time, reducing the retention of material in the weighing hopper 23, and improving continuous batching.

[0069] By setting a movable cleaning component, during mixing, the cleaning box 11 is located on one side of the mixing tank 3, which does not affect the agitator 5 from descending into the mixing tank 3; during cleaning, the cleaning box 11 slides to directly below the agitator 5, so that the mixing process and the cleaning process are independent of each other, avoiding the cleaning box 11 occupying the space above the mixing tank 3 for a long time. Since the cleaning box 11 is moved to directly below the agitator 5, the agitator 5 can be cleaned in the cleaning box 11 without disassembly, reducing manual disassembly and cleaning steps, reducing the intensity of operation, and reducing the adhesion and hardening of residual cement adhesive on the agitator 5.

[0070] By pushing the corresponding positioning block 18 outward along the through groove of the support leg 16 by the electromagnetic push rod 17, the positioning block 18 is inserted into the positioning groove 15 on the inner wall of the fixed seat 1, so that the mixing tank 3 completes circumferential limiting and radial positioning in the fixed seat 1. The mixing tank 3 remains stable and centered in the fixed seat 1, thereby ensuring that the central axis of the mixing tank 3 and the rotation axis of the stirrer 5 are on the same vertical line. When the stirrer 5 descends, it accurately passes through the slot 7 and enters the interior of the mixing tank 3, avoiding collision between the stirrer 5 and the edge of the slot 7 or the inner wall of the mixing tank 3 due to the displacement of the mixing tank 3.
