Description

Technical Field

[0001] The present invention relates to the technical field of ash cake pasting devices, and in particular to an automatic ash cake pasting device. Background Art

[0002] In building plastering projects, a mortar cake is a square block (usually 5cm long) made of cement mortar, serving as a reference point. Its core function is to provide a basis for subsequent large-scale plastering by precisely controlling elevation, wall flatness, and verticality. Traditionally, this process requires manual labor: using a spirit level to determine the mortar cake's position, kneading the mortar into a block and applying it to the wall, and using a ruler to adjust the spatial relationship between the mortar cake surface and the intended plastering surface.

[0003] However, the existing technology has certain technical defects:

[0004] First, human error is significant: the thickness deviation of manually kneaded plaster cakes often reaches more than ±3mm, resulting in uncontrolled flatness of the plaster layer. Relying on multiple levels of manual layout, the cumulative error can exceed the allowable value of the specification;

[0005] Second, construction efficiency is low: shaping and calibrating a single plaster cake takes 3-5 minutes, but high-rise buildings require thousands of plaster cakes, resulting in long construction times and the need for multiple surveyors and plasterers, which drives up labor costs.

[0006] Third, quality risk: Insufficient manual compaction can easily lead to hollowing and falling off, and the lack of vibration can cause micropores to form inside the ash cake, affecting the crack resistance of the subsequent plaster layer.

[0007] In view of this, the present invention proposes an automatic ash cake pasting device. Summary of the Invention

[0008] The present invention provides an automatic ash cake pasting device, which solves the problems in the prior art.

[0010] One end of the inner side of the shell is fixedly connected to a mortar bin, the outer side of the mortar bin is fixedly connected to a base, the four corners of the base are fixedly connected to hydraulic pumps, the output ends of the four hydraulic pumps are fixedly connected to the same hydrophobic coated metal disk, a high-frequency polarization motor is fixedly installed between the back side of the hydrophobic coated metal disk and the base, the outer side of the hydrophobic coated metal disk is rotatably connected to four silicone sheets distributed at equal angles around the hydrophobic coated metal disk, two of the silicone sheets are fixedly connected to the inner sides of metal hoses passing through the silicone sheets, the inlet ends of the two metal hoses are connected to mortar piston pumps, the two mortar piston pumps are respectively fixedly installed at the two ends of the inner side of the shell, the inlet ends of the two mortar piston pumps are fixedly connected to a slurry extraction pipe communicated with the inside of the mortar bin, and the outer edge of the base is provided with a number of driving parts for driving each silicone sheet to rotate.

[0011] Preferably, both ends of the shell are fixedly connected with infrared ranging heads, both ends of the inner side of the shell are fixedly connected with gyroscopes, a control module is provided at the top end of the inner side of the shell, and the infrared ranging head and gyroscope are both signal-connected to the control module.

[0012] Preferably, the driving member includes a gear coaxially fixedly connected to the silicone sheet, a driving motor is fixedly mounted on the outer edge of the base, an output shaft of the driving motor is fixedly connected to an arcuate gear disk, and the arcuate gear disk is engaged with the gear.

[0013] Preferably, the thickness of the arc-shaped toothed disc is greater than the thickness of the gear, and the gear can move along the axis of the arc-shaped toothed disc.

[0014] Preferably, a hopper is fixedly connected to the top of the mortar bin, and an ultrasonic level meter connected to the control module signal is fixedly connected to one end of the top of the mortar bin.

[0015] Preferably, the control module includes a control panel fixedly connected to the inner side of the shell, a dial button electrically connected to the control panel is fixedly connected to the top of the shell, the power input end of the control panel is electrically connected to a lithium battery pack, and the input end of the lithium battery pack is electrically connected to a charging connector.

[0016] Preferably, the control panel includes a processor, the infrared ranging head, gyroscope, and ultrasonic level meter are all connected to the processor signal, and the hydraulic pump, high-frequency polarization motor, and mortar piston pump are all electrically connected to the processor.

[0017] Preferably, a display electrically connected to the processor is fixedly connected to the outer side of the housing, and the display is used to display the inclination of the hydrophobic coated metal disk.

[0018] The working principle and beneficial effects of the present invention are:

[0019] 1. The laser line-setting instrument and the laser sensor on the housing automatically receive laser signals and calculate the position and thickness of the plaster cake. An infrared rangefinder and gyroscope monitor the distance to the wall and the device's posture in real time. This data, combined with the control module's processor, provides feedback to ensure precise adjustment of the hydrophobic-coated metal disc. A hydraulic pump drives the disc, aligning its surface with the intended plaster surface, eliminating the accumulated errors of traditional manual kneading and line-setting. Compared to traditional processes, this device achieves plaster cake thickness and flatness accuracy exceeding industry standards, reducing rework.

[0020] 2. The automated process involves supplying slurry from a mortar silo, and then using a mortar piston pump to squeeze mortar into the gaps between the silicone sheets through a slurry extraction pipe and a metal hose, forming a terraced mortar cake. Drivers (such as gears and curved toothed discs) rapidly rotate the silicone sheets, automatically releasing the mortar cakes. The entire mortar placement process is coordinated by a control module, minimizing the time required from positioning to release, significantly reducing the time required for a single mortar placement operation. When high-rise buildings require thousands of mortar cakes, construction time is shortened and labor requirements are reduced from multiple people working together to a single person monitoring, significantly reducing labor costs.

[0021] 3. The high-frequency polarization motor is installed on the back of the hydrophobic-coated metal disk. After the mortar is squeezed in, high-frequency vibration is started to densify the interior of the slurry and eliminate micropores. A 2-3mm gap is reserved between the silicone sheet and the wall to allow excess slurry to be squeezed out and enhance the adhesion to the wall. The control module monitors the vibration intensity and slurry status in real time through the lithium battery pack and processor to ensure that the internal structure of the mortar cake is uniform and the shape of the mortar cake (step design) is more firmly bonded to the wall, reducing the risk of cracking in the later plaster layer and extending the life of the building.

[0031] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0032] like Figures 1 to 7 As shown, this embodiment proposes an automatic putty cake device, including a laser line marker 4 arranged at the bottom end of the wall 1, a putty cake mechanism 2 is arranged above the laser line marker 4, and the putty cake mechanism 2 includes a shell 21, the bottom wall and side walls of the shell 21 are fixedly connected with ear plates 22, the inner sides of the two ear plates 22 are hinged with telescopic rods 3, and laser photosensitive films 28 are embedded on all four sides of the outer wall of the shell 21; the height and horizontal position of the shell 21 can be adjusted by controlling the telescopic rod 3, thereby adjusting the putty cake position and height of the putty cake mechanism 2 to meet the actual putty cake height requirements.

[0033] One end of the inner side of the shell 21 is fixedly connected to the mortar bin 23, the outer side of the mortar bin 23 is fixedly connected to the base 251, the four corners of the base 251 are fixedly connected to the hydraulic pumps 252, the output ends of the four hydraulic pumps 252 are fixedly connected to the same hydrophobic coated metal disk 253, a high-frequency polarization motor 254 is fixedly installed between the back side of the hydrophobic coated metal disk 253 and the base 251, the outer side of the hydrophobic coated metal disk 253 is rotatably connected to four silicone sheets 258 distributed at equal angles around the hydrophobic coated metal disk 253, two of which are fixedly connected to the inner sides of the silicone sheets 258 with metal hoses 257 penetrating the silicone sheets 258, and two metal The inlet ends of the hose 257 are connected to the mortar piston pump 255, and the two mortar piston pumps 255 are respectively fixedly installed at the two ends of the inner side of the shell 21. The inlet ends of the two mortar piston pumps 255 are fixedly connected to the slurry extraction pipe 256 that is connected to the inside of the mortar bin 23. The outer edge of the base 251 is provided with a number of driving parts 259 for driving each silicone sheet 258 to rotate. Both ends of the shell 21 are fixedly connected to the infrared ranging head 26, and both ends of the inner side of the shell 21 are fixedly connected to the gyroscope 27. The top of the inner side of the shell 21 is provided with a control module 29, and the infrared ranging head 26 and the gyroscope 27 are both connected to the control module 29 signal.

[0034] Adjust the position of the laser line gauge 4 according to the wall positioning line, so that the distance between the laser scanning surface and the proposed plastering surface and a certain set distance (with 10 to 20 cm from the wall as a reference line), and input the distance into the device at the same time to ensure that the position of the ash cake surface can just correspond to the distance;

[0035] The laser sensitive sheet 28 can ensure that both sides can receive the laser emitted by the laser line meter 4, and automatically determine the required overall thickness of the ash cake. When the distance calculation is completed, the four hydraulic pumps 252 located on the back side of the hydrophobic coated metal plate 253 are started to adjust the front and rear position and inclination of the hydrophobic coated metal plate 253 so that its left surface is exactly on the surface of the ash cake to be formed. This ensures that the ash cake produced is exactly consistent with the surface of the wall to be plastered later, achieving the desired ash cake effect.

[0036] After the hydrophobic coated metal disc 253 is adjusted in position, the next step is to start working with the two mortar piston pumps 255 corresponding to the metal hose 257 located inside the silicone sheet 258, squeezing the mortar into the mortar cake area between the four silicone sheets 258 through the mortar piston pumps 255 to form a mortar cake. A gap (2-3 mm) is left between the silicone sheets 258 and the wall. The amount of mortar discharged is calculated by the infrared ranging head 26, multiplied by the cake area to obtain the desired thickness, and increased by about 1.5 times. This allows the excess mortar to be squeezed out of the 2-3 mm gap, forming a stepped mortar cake shape that can better adhere to the wall. After the mortar is squeezed into the cake discharge area, the high-frequency polarization motor 254 behind the hydrophobic coated metal disc 253 starts working. Its position remains unchanged, but the high-frequency vibration of the polarization motor can vibrate the slurry, making it more dense and more firmly adhered to the wall.

[0037] After the ash cake is vibrated and tightly adhered to the wall, the four hydraulic pumps 252 move back slightly, and by starting the driving part 259, all the silicone sheets 258 are driven to rotate and open along the axis, so that the ash cake is completely separated from the equipment. At this time, the cake making is completed and the process is ended. The whole process takes a short time, is fast and accurate, and greatly improves the work efficiency of sticking ash cakes.

[0038] Furthermore, the driving member 259 includes a gear 2591 coaxially fixedly connected to the silicone sheet 258, a driving motor 2592 is fixedly installed on the outer edge of the base 251, and an output shaft of the driving motor 2592 is fixedly connected to an arc-shaped toothed disc 2593, which is meshed with the gear 2591. The thickness of the arc-shaped toothed disc 2593 is greater than the thickness of the gear 2591, and the gear 2591 can move along the axial direction of the arc-shaped toothed disc 2593.

[0039] By starting the driving motor 2592 to drive the corresponding arc-shaped toothed disc 2593 to rotate, the gear 2591 is rotated, and the corresponding silicone sheet 258 is rotated and opened along the axis, so that the ash cake is completely separated from the equipment, so that the ash cake can be tightly adhered to the wall, thus realizing automatic adhesion of the ash cake.

[0040] Furthermore, a hopper 24 is fixedly connected to the top of the mortar bin 23, and one end of the top of the mortar bin 23 is fixedly connected to an ultrasonic level meter that is signal-connected to the control module 29; the ultrasonic level meter is used to detect the amount of mortar inside the mortar bin 23, and the hopper 24 is used to replenish mortar into the mortar bin 23.

[0041] Furthermore, the control module 29 includes a control panel 291 fixedly connected to the inner side of the shell 21, a dial button 292 electrically connected to the control panel 291 is fixedly connected to the top of the shell 21, the power input end of the control panel 291 is electrically connected to the lithium battery pack 293, and the input end of the lithium battery pack 293 is electrically connected to the charging connector 294. The control panel 291 includes a processor, the infrared ranging head 26, the gyroscope 27, and the ultrasonic level meter are all connected to the processor signal, the hydraulic pump 252, the high-frequency polarization motor 254 and the mortar piston pump 255 are all electrically connected to the processor, and a display electrically connected to the processor is fixedly connected to the outside of the shell 21, and the display is used to display the inclination of the hydrophobic coated metal disk 253.

[0042] The thickness of the silicone sheet 258 is 3 cm, and it can be replaced with two specifications of 4 cm and 5 cm. When the wall error is large and the ash cake is thin, the hydrophobic coated metal plate 253 can extrude the silicone sheet 258 to achieve it; when the wall deviation is too large and the ash cake thickness is less than 0, or it is only a few millimeters and the cake cannot be pasted, the infrared ranging head 26 will issue an alarm after monitoring the data. At this time, the wall needs to be manually trimmed. In addition, when the thickness of the hydrophobic coated metal plate 253 is not enough to meet the required thickness of the iron ash cake, an alarm will also be issued.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
