Description

Technical Field

[0001] This invention relates to the field of building construction equipment technology, and in particular to a device for quantitatively applying and kneading ceramic tile adhesive. Background Technology

[0002] As a core substrate in building decoration projects, ceramic tiles are widely used in indoor and outdoor wall and floor paving operations. The firmness and stability of tile laying directly determine the construction quality and service life of building decoration projects. In the tile laying construction process, applying tile back adhesive is a key pre-process. By evenly applying special back adhesive to the back of the tile, the adhesion between the tile and the adhesive mortar can be effectively enhanced, avoiding quality problems such as tile hollowing, falling off, and curling, and greatly improving the adaptability and durability of tile laying. Currently, the mainstream tile adhesive application operations on the market are divided into two methods: manual application and semi-automatic equipment application. Among them, manual application relies on construction workers to manually apply the adhesive with tools such as scrapers and brushes. The work efficiency is extremely low and cannot be adapted to large-scale, large-volume tile processing and production scenarios. Moreover, manual application relies entirely on construction experience, which can easily lead to problems such as uneven adhesive thickness, adhesive area deviation, missed application, and over-application. The consistency of adhesive application is poor, which seriously affects the quality of subsequent tile laying. At the same time, manual operation is labor-intensive and costly, which does not meet the development needs of automation and standardization in modern building materials processing. Although existing semi-automatic tile adhesive application equipment has replaced some manual operations and realized mechanized adhesive application, its overall structural design is rudimentary, its functionality is limited, and it has many technical defects. Most existing equipment only has simple fixed-point adhesive injection and single-time adhesive scraping functions, and lacks a precise material conveying control structure, an adaptive adhesive adjustment structure, and a uniform coating and pressing structure. It cannot realize the integrated operation of quantitative conveying, dynamic adjustment, and uniform coating of tile back adhesive. To address the aforementioned problems, this invention proposes a device for quantitatively applying and kneading ceramic tile backing adhesive. Summary of the Invention

[0003] This invention provides a quantitative coating and kneading device for ceramic tile backing adhesive, which solves the problems of low efficiency, poor consistency and uneven coating of existing manual coating and semi-automatic equipment.

[0004] This invention provides the following technical solution: A tile adhesive metering and kneading device includes a frame, a support box fixedly installed on one side of the top of the frame, and a limiting frame fixedly installed on the top of the frame within the support box. The limiting frame is used to limit the position of the tile. The device also includes: A conveying component, mounted on the equipment frame, is used to drive the tile to move laterally into or out of the support box; The injection component penetrates the top inner wall of the support box and is slidably connected to the support box for conveying tile adhesive; A coating component, installed at the bottom of the injection component, is used to evenly apply the tile adhesive onto the tile. A material conveying component is installed on the equipment frame, the top of which extends above the support box and is connected to the injection component for conveying tile adhesive to the injection component; The conveying component drives the tile into the support box, the material conveying component delivers tile adhesive to the injection component, the injection component delivers tile adhesive to the coating component, and the coating component evenly applies tile adhesive to the tile.

[0005] In one possible design, the conveying component includes a plurality of transmission rollers rotatably connected within the equipment frame and a first drive motor fixedly mounted on one side of the equipment frame. The output shaft of the first drive motor is fixedly connected to one end of one of the transmission rollers, and the other ends of the plurality of transmission rollers are connected via a transmission assembly. The first drive motor drives the transmission rollers to rotate, and the transmission assembly drives the plurality of transmission rollers to rotate synchronously, thereby driving the tile to move.

[0006] In one possible design, the transmission assembly includes multiple belt assemblies, each belt assembly including two synchronous pulleys and a synchronous belt sleeved on the two synchronous pulleys, with the two synchronous pulleys respectively fixedly sleeved on two adjacent transmission rollers.

[0007] In one possible design, the injection component includes a slide plate slidably connected to the inner wall of the top of the support box, a support tube slidably connected to the slide plate, a support frame fixedly installed on the top of the slide plate, and a first stepper motor fixedly installed on the top of the support frame. The support tube slidably passes through the support frame, and a mounting bracket is fixedly sleeved on the support tube. A transmission nut is fixedly installed on the mounting bracket. A transmission screw is fixedly installed on the output shaft of the first stepper motor. The transmission screw is threadedly connected to the transmission nut. The first stepper motor drives the transmission screw to rotate, thereby causing the mounting bracket and the support tube to move longitudinally and adjusting the height of the coating component.

[0008] In one possible design, an electric push rod is fixedly installed at the top of the support tube. The output shaft of the electric push rod extends into the support tube and is fixedly installed with a push plate. The push plate is in contact with the inner wall of the support tube. The electric push rod drives the push plate to move longitudinally along the inner wall of the support tube to scrape off the tile adhesive adhered to the inner wall of the support tube.

[0009] In one possible design, a drive box is also fixedly installed on the top of the support box. A second stepper motor is fixedly installed on one side of the drive box. The output shaft of the second stepper motor extends into the drive box and is fixedly installed with a drive screw. A threaded plate is threaded onto the drive screw. One side of the threaded plate extends to the outside of the drive box and is fixedly connected to the support frame. The second stepper motor drives the drive screw to rotate in both directions, thereby causing the threaded plate and the support frame to move laterally back and forth, so that the coating component moves laterally to disperse and apply tile adhesive.

[0010] In one possible design, the coating component includes an assembly box fixedly installed at the bottom of the support pipe, a distribution box fixedly installed inside the assembly box, and coating and pressing components symmetrically installed at the bottom of the assembly box. The top opening of the distribution box communicates with the support pipe, and conveying pipes are fixedly installed on both inner walls of the distribution box. A dispersing component is installed on one side of the assembly box. The dispersing component passes through the two conveying pipes and the distribution box and is used to disperse and convey tile adhesive into the two conveying pipes. The tile adhesive output from the conveying pipes enters the coating and pressing component, and the coating and pressing component evenly applies the tile adhesive onto the tile.

[0011] In one possible design, the dispersing assembly includes a second drive motor fixedly mounted on one side of the assembly box. The output shaft of the second drive motor is fixedly mounted with a dispersing shaft, which passes through the distribution box and the two conveying pipes respectively. Two dispersing spiral blades are symmetrically fixedly sleeved on the dispersing shaft and located in the two conveying pipes respectively. The sides of the two dispersing spiral blades that are close to each other extend into the distribution box. The second drive motor drives the dispersing shaft and the two dispersing spiral blades to rotate, so as to push the tile adhesive into the two conveying pipes.

[0012] In one possible design, the coating assembly includes two mounting boxes symmetrically fixedly mounted on the bottom of the assembly box. Each mounting box has a discharge pipe fixedly mounted on its bottom. One inner wall of the discharge pipe communicates with the bottom of the assembly box via a flow pipe. A rotating shaft is rotatably connected to the top inner wall of each mounting box. The bottom end of the rotating shaft passes through the discharge pipe and is fixedly mounted with a scraper. The two scrapers are arranged at an angle of °. A first conveying spiral blade located inside the discharge pipe is fixedly sleeved on the rotating shaft. A fixing box is fixedly mounted on the bottom of the assembly box, and a rotating... A connecting shaft is connected, with both ends extending into the two mounting boxes respectively. The connecting shaft meshes with the transmission bevel gear on the rotating shaft via a drive bevel gear. A servo motor is fixedly installed on one side of the fixed box. A worm gear is fixedly sleeved on the output shaft of the servo motor. A worm wheel that drives the worm gear is fixedly sleeved on the connecting shaft. Tile adhesive flows into the discharge pipe through the flow pipe. The servo motor drives the connecting shaft and the rotating shaft to rotate. The first conveying spiral blade rotates to convey the tile adhesive downwards. The scraper rotates to evenly scrape the tile adhesive onto the tile.

[0013] In one possible design, the material conveying component includes a material holding box fixedly installed within the equipment frame, a discharge box fixedly installed on the inner wall of the bottom of the material holding box, and a third stepper motor fixedly installed on one side of the discharge box. The output shaft of the third stepper motor is fixedly equipped with a second conveying spiral blade. A conveying pump is fixedly installed on the bottom of the other side of the discharge box. The discharge end of the conveying pump is connected to the support pipe through a hose. Tile adhesive is injected into the material holding box. The third stepper motor drives the second conveying spiral blade to rotate to convey the tile adhesive to the suction end of the conveying pump. The conveying pump pumps the tile adhesive into the support pipe through the hose.

[0014] In this invention, during use, tile adhesive is first injected into the container through the injection port. Then, the third stepper motor is started to drive the second conveying spiral blades to rotate, moving the tile adhesive towards the suction end of the conveying pump. The conveying pump is then started to extract the tile adhesive, which is then injected into the support pipe through a hose, achieving continuous feeding. The tile is placed on multiple drive rollers, and the first drive motor is started to drive the corresponding drive rollers to rotate. Under the transmission action of multiple synchronous pulleys and belts, multiple drive rollers rotate synchronously, thereby driving the tile to move laterally and move it into the support box, allowing the tile to enter the limiting area of ​​the limiting frame. The process is then adjusted according to the size of the tile and the coating... To adjust the height of the coating component, the first stepper motor is started, driving the transmission screw to rotate. Under the threaded transmission with the transmission nut, the mounting bracket moves longitudinally, thereby moving the support tube longitudinally and adjusting the height of the coating component. Simultaneously, the second stepper motor is started, driving the drive screw to rotate, causing its output shaft to rotate in both directions at a certain cycle. Under the threaded transmission between the drive screw and the threaded plate, the threaded plate moves laterally along the drive screw, thereby moving the support bracket laterally. This achieves lateral adjustment of the coating component's position, allowing the tile adhesive to be dispersed and applied to the tile. After the tile adhesive flows into the distribution box through the support tube, the second stepper motor is started... Two drive motors rotate the dispersing shaft, which in turn rotates the two dispersing spiral blades, dispersing and conveying the tile adhesive into two conveying pipes. After flowing through the two conveying pipes, the tile adhesive flows into the discharge pipe through two flow pipes. At this time, the servo motor is activated to drive the worm gear to rotate, which, under the meshing transmission action with the worm wheel, drives the connecting shaft to rotate. When the connecting shaft rotates, it drives the two drive bevel gears to rotate, which, under the meshing transmission action with the two drive bevel gears, drives the corresponding rotating shaft to rotate. When the rotating shaft rotates, it drives the first conveying spiral blade and the scraper to rotate. When the first conveying spiral blade rotates, it conveys the tile adhesive downwards, while the two blades at an angle of °... The angled scraper evenly applies tile adhesive to the tile as it rotates. The rubber strip at the bottom of the scraper increases adhesion to the tile surface, achieving a smooth and compacting process. Because the scraper can reciprocate laterally and adjust its height, it ensures the adhesive is evenly applied. When the adhesive is conveyed to the coating component through the support tube, if it adheres to the inner wall of the tube, the electric push rod is activated, moving the push plate downwards. The push plate scrapes against the inner wall of the support tube, removing the adhesive and preventing blockage. After application, the first drive motor is activated in reverse to move the tile out of the support box, completing the entire coating and compacting process.

[0015] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention. Beneficial effects

[0016] 1. Through the set conveying components, the first drive motor drives the transmission roller to rotate, and the transmission assembly composed of synchronous pulleys and synchronous belts realizes the synchronous rotation of multiple transmission rollers, thereby stably and evenly driving the tiles to move laterally, automatically moving the tiles into or out of the support box. Compared with manual handling, it greatly reduces labor intensity, improves the efficiency of tile loading and unloading and the convenience of operation. At the same time, the protective cover can effectively protect the transmission assembly, prevent dust and other foreign objects from entering, and extend the service life of the equipment. 2. Through the set injection component, the first stepper motor drives the transmission screw to rotate, and under the thread transmission action with the transmission nut, it drives the mounting frame to move longitudinally, thereby driving the support tube and coating component to adjust the height. It can flexibly adjust the height of the coating component according to the size of different specifications of tiles and the coating height requirements, realizing precise control of the tile adhesive coating height, improving the applicability of the equipment and the coating uniformity. At the same time, by setting a second stepper motor to drive the drive screw to rotate, the threaded plate moves laterally back and forth along the drive screw, thereby driving the support frame and coating component to move laterally back and forth, realizing the dispersed coating of tile adhesive on the tile surface, avoiding the problem of uneven thickness caused by concentrated coating of tile adhesive, and further improving the coating quality. 3. By setting up a coating component, the second drive motor in the dispersion assembly drives the dispersion shaft and dispersion spiral blades to rotate, dispersing and conveying the tile adhesive flowing into the distribution box into two conveying pipes, achieving uniform distribution of the tile adhesive. Then, the servo motor in the coating assembly drives the worm gear to rotate, and through the worm wheel, connecting shaft, drive bevel gear and transmission bevel gear, the scraper on the rotating shaft and the first conveying spiral blade rotate synchronously. The first conveying spiral blade conveys the tile adhesive downwards, and the rubber strips at the bottom of the two scrapers set at an angle of ° can evenly scrape and knead the tile adhesive onto the tile surface. The rotation and kneading action of the scraper makes the tile adhesive fully adhere to the back of the tile, improving the bonding effect. At the same time, the scraper can realize lateral reciprocating motion and height adjustment, so that the tile adhesive can be uniformly coated on the tile surface from all directions and multiple angles. The coating and kneading effect is significantly better than the traditional unidirectional coating method, greatly improving the construction quality and efficiency of tile laying.

[0017] This invention automatically drives the movement of the tile through a conveying component, allows for flexible adjustment of the height and position of the coating component through an injection component, and coordinates the dispersing component and the coating pressing component to evenly disperse the tile adhesive and apply it through a scraper. At the same time, the electric push rod can clean the residue in the pipe to prevent blockage. This invention realizes the integrated operation of quantitative conveying, dynamic positioning, and uniform coating and kneading of tile adhesive, solving the problems of low efficiency and poor consistency of manual coating and the single functionality and uneven coating of existing equipment.

[0020] The embodiments of the present invention will now be described with reference to the accompanying drawings.

[0021] In the description of the embodiments of the present invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connection" and "installation" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. Furthermore, "connection" can be a direct connection or an indirect connection through an intermediate medium. "Fixed" means that the devices are connected to each other and their relative positional relationship remains unchanged after the connection. The directional terms mentioned in the embodiments of the present invention, such as "inner," "outer," "top," and "bottom," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of the present invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of the present invention.

[0022] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0023] In this embodiment of the invention, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0024] References to "one embodiment" or "some embodiments" as used in this specification mean that a particular feature, structure, or characteristic described in connection with that embodiment is included in one or more embodiments of the invention. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including, but not limited to," unless otherwise specifically emphasized.

[0025] In one embodiment: Refer to Figure 1-9 A coating and kneading device includes an equipment frame 1, a support box 7, a limiting frame 8, a conveying component, an injection component, a coating component, and a conveying component.

[0026] like Figure 1-3 As shown, the equipment frame 1 serves as the supporting framework for the entire equipment. A support box 7 is bolted to one side of the top of the equipment frame 1. The support box 7 is constructed of bent and welded steel plates, forming an internal working chamber. A limiting frame 8 is fixedly installed on the top of the equipment frame 1, inside the support box 7. This limiting frame 8 consists of two parallel angle steels with a cross-section of 20mm × 20mm. The distance between the two angle steels can be adjusted according to the width of common ceramic tiles, for example, within a range of 300mm to 800mm. This limiting frame is used to laterally limit the width of the ceramic tile 9 placed on it, preventing it from shifting during subsequent adhesive application.

[0027] like Figure 1-3 As shown, a conveying component is mounted on a frame 1 to drive the tile 9 to move laterally. The conveying component includes multiple drive rollers 2 rotatably connected at equal intervals within the frame 1. Their surfaces are covered with a rubber layer to increase friction and prevent scratching the tiles. The axes of the multiple drive rollers 2 are on the same horizontal plane, providing rolling support for the tile 9. On one side of the frame 1, a first drive motor 3 is fixedly mounted via a motor mount. The output shaft of the first drive motor 3 extends into the frame 1 via a key connection and is fixedly connected to one end of a drive roller 2 located on one side. The other ends of the multiple drive rollers 2 extend to the other side of the frame 1 and are linked by a transmission assembly. The transmission assembly includes multiple belt assemblies, each corresponding to two adjacent drive rollers 2. Each belt assembly includes two synchronous pulleys 4 and a synchronous belt 5. The two synchronous pulleys 4 are fixedly fitted onto the extended ends of two adjacent drive rollers 2 via key connections. The synchronous belt 5 is fitted onto the two synchronous pulleys 4 and engages with them for transmission. On the other side of the equipment frame 1, a protective cover 6 is fixedly installed with screws to enclose multiple synchronous pulleys 4 and synchronous belts 5, serving as a dustproof and safety protection. When the tile 9 is placed on the multiple drive rollers 2, the first drive motor 3 is started, which drives the drive rollers 2 directly connected to it to rotate. Through the transmission of the synchronous pulleys 4 and synchronous belts 5, all drive rollers 2 will rotate synchronously in the same direction, thereby driving the tile 9 to move smoothly laterally, enabling it to be fed into or removed from the support box 7.

[0028] like Figure 1-7As shown, a sliding hole is provided on the inner wall of the top of the support box 7. The injection component passes through the sliding hole and is slidably connected to it. The injection component includes a slide plate 10, a support tube 11, a support frame 31, a first stepper motor 32, a transmission screw 33, a mounting bracket 34, and a transmission nut 35. The slide plate 10 slides in contact with the inner wall of the sliding hole at the top of the support box 7, and the sliding surface is coated with grease. The support tube 11 passes through a through hole in the middle of the slide plate 10 and can slide up and down in the through hole. The support frame 31 is fixed to the top of the slide plate 10 by welding and has a horizontal top plate. The support tube 11 passes upward through a hole in the top plate and is slidably connected to it. The first stepper motor 32 is fixedly mounted on one side of the top plate of the support frame 31 by bolts, and its output shaft is vertically downward. The transmission screw 33 is fixedly connected to the output shaft of the first stepper motor 32 by a coupling. The mounting bracket 34 is fixedly sleeved on the support tube 11 by two clamps and is located above the slide plate 10. The transmission nut 35 is fixedly mounted on the top side of the mounting bracket 34 by bolts. The bottom end of the transmission screw 33 passes sequentially through the transmission nut 35 and the light hole on the mounting bracket 34, and is finally rotatably connected to the slide plate 10 via a thrust ball bearing. The transmission screw 33 and the transmission nut 35 form a threaded transmission pair. When the first stepper motor 32 is started to drive the transmission screw 33 to rotate, since the transmission nut 35 is restricted from rotating by the mounting bracket 34, the mounting bracket 34 will drive the support tube 11 to move vertically under the action of the threads, thereby adjusting the height of the bottom end of the support tube 11. In this embodiment, the step angle of the first stepper motor 32 is 1.8°, which, together with the transmission screw 33 with a lead of 5mm, enables precise adjustment of the height position of the support tube 11.

[0029] like Figure 7 As shown, an electric push rod 29 is fixedly installed at the top of the support pipe 11 via a flange. The push rod output shaft of the electric push rod 29 extends downward into the support pipe 11, and its end is fixedly installed with a push plate 30 via screws. The outer edge of the push plate 30 is clearance-fitted with the inner wall of the support pipe 11, with the clearance controlled within 0.5mm. When the tile adhesive is conveyed downward through the support pipe 11, some of the more viscous adhesive may adhere to the pipe wall. Without this structure, after long-term operation, the adhesive layer on the pipe wall will gradually thicken, not only reducing the effective flow cross-section and affecting the accuracy of quantitative conveying, but also potentially causing blockage due to peeling off of the cured adhesive when the ambient temperature changes. By periodically activating the electric push rod 29 to drive the push plate 30 downward, the adhesive adhering to the pipe wall can be scraped off, keeping the pipeline unobstructed. The push plate 30 stops and returns when it reaches near the bottom of the support pipe 11 to avoid interfering with the normal discharge below.

[0030] like Figure 9As shown, to drive the overall lateral movement of the injection component, a drive box 36 is bolted to the top of the support box 7. A second stepper motor 37 is fixedly mounted on one side of the drive box 36. The output shaft of the second stepper motor 37 extends horizontally into the drive box 36 and is fixedly connected to a drive screw 38 via a coupling. The other end of the drive screw 38 is rotatably connected to the inner wall of the drive box 36 via a deep groove ball bearing. A threaded plate 39 is threaded onto the drive screw 38. One side of the threaded plate 39 extends outward through an elongated hole in the side wall of the drive box 36 and is bolted to the side of the support frame 31. Starting the second stepper motor 37 and controlling its forward and reverse rotation according to a preset cycle can drive the drive screw 38 to rotate reciprocally, thereby causing the threaded plate 39 to drive the entire support frame 31, slide plate 10, and support tube 11 to move laterally reciprocally along the sliding hole. This design allows the adhesive flowing from the support tube 11 to be dispersedly distributed to different lateral starting positions on the back of the tile 9, rather than starting from a single fixed point. This is especially important for wider tiles, as it prevents insufficient adhesive at the edges when the adhesive is spread from the center.

[0031] like Figure 5-8 As shown, the coating component is fixedly installed at the bottom end of the support pipe 11 to receive the adhesive and perform the coating operation. The coating component includes an assembly box 12, a distribution box 13, a delivery pipe 14, a dispersion assembly, and a coating assembly. The assembly box 12 is a rectangular box, the top of which is fixedly connected to the bottom end of the support pipe 11 via a flange. The distribution box 13 is welded and fixed to the center of the interior of the assembly box 12, and its top opening is directly aligned and connected to the bottom outlet of the support pipe 11. A delivery pipe 14 is welded and fixed to the inner walls of both sides of the distribution box 13. The two delivery pipes 14 are arranged horizontally and their axes coincide. Their proximal ends are connected to the interior of the distribution box 13, and their distal ends extend to both sides of the distribution box 13. The dispersion assembly is used to convey the adhesive flowing into the distribution box 13 to both sides. The dispersion assembly includes a second drive motor 15 fixed to the outer wall of one side of the assembly box 12 by bolts. The output shaft of the second drive motor 15 passes horizontally through a sealed bearing on the side wall of the assembly box 12 and is fixedly mounted with a dispersion shaft 16. The other end of the dispersing shaft 16 is rotatably connected to the inner wall of the other side of the assembly box 12 via a bearing. The dispersing shaft 16 passes sequentially through the distribution box 13 and two conveying pipes 14. On the dispersing shaft 16, in the sections located within the two conveying pipes 14, dispersing spiral blades 17 are fixedly fitted by key connections. The two dispersing spiral blades 17 rotate in opposite directions, and their ends both extend to the central area inside the distribution box 13. When the adhesive material falls from the support pipe 11 into the distribution box 13, the second drive motor 15 is started to drive the dispersing shaft 16 to rotate. The two dispersing spiral blades 17 rotate synchronously, which can push the adhesive material accumulated in the middle of the distribution box 13 to the left and right conveying pipes 14 respectively, realizing the uniform dispersion and conveying of the adhesive material.

[0032] like Figure 7-8 As shown, the coating assembly is symmetrically arranged at the bottom of the assembly box 12, used to finally apply and press the adhesive onto the tile surface. The coating assembly includes two mounting boxes 18, a discharge pipe 20, a flow pipe 21, a rotating shaft 19, a scraper 22, a first conveying spiral blade 23, a fixed box 24, a connecting shaft 25, a servo motor 26, a worm gear 27, and a worm wheel 28. The two mounting boxes 18 are symmetrically fixed to the bottom sides of the assembly box 12 by bolts. A discharge pipe 20 is welded and fixed to the bottom opening of each mounting box 18. The upper end of the flow pipe 21 is welded and connected to the bottom of the assembly box 12, and the lower end is inclined and inserted into one side of the corresponding discharge pipe 20 and welded and fixed thereto, thereby guiding the adhesive output from the conveying pipe 14 into the discharge pipe 20. The rotating shaft 19 is rotatably connected to the top inner wall of the mounting box 18 through a bearing seat at its upper end, and its lower end passes through the bottom of the mounting box 18 and the discharge pipe 20 and extends to the outside. A first conveying spiral blade 23 is fixedly mounted on the rotating shaft 19 section located inside the discharge pipe 20 via a key connection. A scraper 22 is bolted to the bottom end of the rotating shaft 19 extending out of the discharge pipe 20. The two scrapers 22 are arranged at a 90° angle. A rubber strip, made of nitrile rubber with a Shore A hardness of 60±5, is embedded in the bottom of the scraper 22. A fixed housing 24 is welded to the bottom of the assembly housing 12 between the two mounting housings 18. A connecting shaft 25 is rotatably connected to the fixed housing 24 via two rolling bearings, with its two ends extending into the left and right mounting housings 18 respectively. A drive bevel gear 251 is fixedly mounted at each end of the connecting shaft 25. A transmission bevel gear 252 is fixedly mounted on the rotating shaft 19 within each mounting housing 18. The drive bevel gear 251 meshes with the transmission bevel gear 252 on the same side. The servo motor 26 is fixed to one side of the fixed housing 24 by a bracket, and its output shaft extends horizontally into the fixed housing 24 and is fixedly mounted with a worm gear 27. A worm wheel 28 is fixedly sleeved on the connecting shaft 25, located inside the fixed housing 24. The worm gear 27 meshes with the worm wheel 28, forming a reduction gear pair with a self-locking function.

[0033] After the adhesive flows into the discharge pipe 20 through the flow pipe 21, the servo motor 26 is activated to drive the worm gear 27 to rotate, which in turn drives the worm wheel 28 and the connecting shaft 25 to rotate. The drive bevel gears 251 at both ends of the connecting shaft 25 rotate accordingly, and through meshing, drive the two transmission bevel gears 252 and the connected rotating shaft 19 to rotate synchronously in the same direction. The rotation of the rotating shaft 19 produces two actions: first, it drives the first conveying spiral blade 23 to rotate, continuously pushing the adhesive in the discharge pipe 20 downward and extruding it from the pipe opening; second, it drives the scraper 22 to rotate. When the two scrapers 22, which are at a 90° angle, rotate, the rubber strips at their bottoms will contact the surface of the tile 9, scraping the extruded adhesive. The 90° angle is chosen based on a balance between the leveling and scraping resistance of common tile adhesives. If the angle is too small (e.g., 45°), the shearing force on the adhesive material during rotation of the scraper is large. While this is beneficial for thinning, it requires high motor torque and can easily cause the adhesive material to be thrown away from the intended area. If the angle is too large (e.g., 180°, i.e., opposite angle), the kneading and spreading effect on the adhesive material will be weakened. The 90° angle in this embodiment ensures an effective coating width while providing moderate kneading pressure, which helps to remove air bubbles under the adhesive layer. The rotation of the scraper 22, combined with the lateral reciprocating motion and height adjustment of the dispensing component, allows the adhesive material to be evenly applied to the entire back of the tile in a spiral trajectory.

[0034] The conveying unit is used to quantitatively supply tile adhesive to the dispensing unit. The conveying unit includes a material container 40, a discharge container 41, a third stepper motor 42, a second conveying spiral blade 43, a conveying pump 44, a hose 45, and a bracket 46. The material container 40 is welded and fixed inside the equipment frame 1, with an open top corresponding to the tile 9 area on the conveying unit to catch any dripping material. The discharge container 41 is welded to the center of the bottom inner wall of the material container 40, and its bottom extends downward through the material container 40. The third stepper motor 42 is bolted to one outer wall of the discharge container 41, with its output shaft extending horizontally into the discharge container 41 and connected to one end of the second conveying spiral blade 43 via a coupling. The other end of the second conveying spiral blade 43 is rotatably connected to the other inner wall of the discharge container 41 via a bearing. The conveying pump 44 is a peristaltic pump, fixed to the bottom of the other side of the discharge container 41 by a bracket, with its suction end inlet pipe extending into the bottom of the discharge container 41. A flexible hose 45 is connected to the discharge end of the conveying pump 44. The flexible hose 45 is a pressure-resistant rubber tube with an inner diameter of 8mm. Its top end passes through a pre-drilled hole in the top of the support box 7 and is fixedly connected to the inner wall of the top side of the support pipe 11 using a pipe fitting. In the middle section of the flexible hose 45, a bracket 46 is fitted and fixed to the top side of the support box 7 to support and guide the hose, preventing it from excessively bending or tangling due to frequent movement with the injection component. A filling port with a funnel is opened on the top side of the material holding tank 40 for replenishing tile adhesive. During operation, tile adhesive is pre-filled into the material holding tank 40. The third stepper motor 42 is started to drive the second conveying spiral blade 43 to rotate, gathering the adhesive at the bottom of the material holding tank 40 into the discharge tank 41 and pushing it towards the inlet of the conveying pump 44. Then, the conveying pump 44 is started to extract a metered amount of adhesive and pump it through the flexible hose 45 into the support pipe 11, completing the feeding process.

[0035] This application can be used in the field of construction equipment technology, or in other fields applicable to this application.

[0036] In another embodiment: an improvement on the above embodiment: a quantitative coating and kneading device for ceramic tile back adhesive, which is applied to the field of building construction equipment technology. The structure of this embodiment is basically the same as the previous embodiment, except that the scraper 22 in the coating and pressing assembly is set in a way that shows different feasible options.

[0037] In this embodiment, the included angle between the two scrapers 22 is set to 45°. This smaller angle design allows the scrapers 22 to exert a stronger shearing and spreading effect on the tile adhesive during rotation. When applying tile adhesives with lower viscosity and better flowability, this structure helps to obtain a thinner and more uniform adhesive film. However, when processing high-viscosity tile adhesives or those containing coarse aggregates, the smaller angle may lead to a significant increase in rotational resistance, higher torque requirements for the servo motor 26, and a greater likelihood of adhesive buildup at the edges of the scrapers 22. Therefore, this 45° angle setting is suitable for specific production scenarios where there are strict and precise requirements for adhesive film thickness and where the adhesive material used has good flowability. During equipment design, scraper assemblies with different included angles can be selected based on the main type of tile adhesive to be processed.

[0038] However, as is well known to those skilled in the art, the working principles and wiring methods of the first drive motor 3, the second drive motor 15, the servo motor 26, the electric push rod 29, the first stepper motor 32, the second stepper motor 37, the third stepper motor 42, and the delivery pump 44 are conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention.
