Description

Technical Field

[0001] This utility model relates to the field of material feeding machine technology, and in particular to a material feeding machine for plastering mortar production. Background Technology

[0002] In plastering mortar production, the production feeding machine is of great significance. It can accurately batch materials, adjust the mix ratio according to project requirements, and ensure stable and diverse quality. It enables automated operation and continuous production, improving efficiency, especially suitable for large-scale production. It can also reduce labor intensity and minimize manual operation and errors. Furthermore, it facilitates management and traceability, storing data to control quality and helping to improve quality management levels. Plastering mortar is a key building material, composed of a mixture of various components. It serves to protect the base layer and smooth the surface, and comes in types such as cement mortar and lime mortar, possessing good workability, suitable strength, adhesion, and durability. During construction, proper base treatment, accurate mixing, layered plastering, and curing are essential to ensure project quality.

[0003] Existing plastering mortar production feeders mainly consist of several key structures. The silo is a container for storing various raw materials, designed with good sealing and anti-caking functions to ensure stable raw material quality. The metering device is a core component, such as a high-precision electronic scale or screw meter, which accurately measures the weight or volume of raw materials like cement, sand, and lime, ensuring accurate feed quantity. Conveying components, such as belt conveyors and screw conveyors, are responsible for stably transporting the metered raw materials from the silo to the mixing area. The control unit acts as the "brain" of the feeder, precisely controlling the operation of each component through preset programs and sensor feedback, coordinating silo discharge, metering accuracy, and conveying rhythm and speed, ensuring the entire feeder process is orderly, efficient, and precise, thus laying a solid foundation for producing high-quality plastering mortar.

[0004] However, in existing technologies, the conveying components of plastering mortar production feeders rely on scrapers for surface cleaning, and the scraper cleaning materials cannot be quickly replaced, leading to a series of serious problems. Because the scraper cleaning materials cannot be replaced in a timely manner when worn or contaminated, their cleaning efficiency continuously diminishes. Material accumulates on the conveying components, increasing the operating load, causing energy consumption to rise steadily, and also accelerating mechanical wear, shortening equipment lifespan, leading to frequent maintenance downtime, and reducing production efficiency. Simultaneously, unclean scrapers easily allow impurities to mix into the mortar raw materials, damaging the uniformity and stability of the plastering mortar, resulting in inconsistent product quality that fails to meet the stringent quality standards of construction, posing a potential threat to the quality and safety of the entire construction project. Therefore, a plastering mortar production feeder is proposed to solve these problems. Utility Model Content

[0005] The purpose of this invention is to provide a feeding machine for plastering mortar production, which aims to improve the problem in the prior art where the cleaning material of the scraper cannot be changed quickly, resulting in a continuous decline in its cleaning efficiency.

[0036] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 This utility model provides an embodiment of a plastering mortar production feeder, including a support 1, which can be made of carbon steel. Carbon steel has high strength and good toughness, and can stably support the other parts of the feeder. A conveyor belt 2 is fixedly connected to the side wall of the support 1, and a baffle 4 is fixedly connected to the top of the support 1. The baffle 4 can be made of stainless steel. The corrosion resistance of stainless steel makes it resistant to contact with mortar and to conditions such as humidity and dust in the production environment. An air compressor 3 is fixedly connected to the bottom of the support 1, and a fixing block 5 is fixedly connected to the side wall of the conveyor belt 2. The fixing block 5 can be made of cast iron. Cast iron has high strength and good shock absorption performance, and can firmly fix components such as hydraulic cylinder 6. The hydraulic cylinder 6 is fixedly connected inside the fixing block 5, and a first support plate 7 is fixedly connected to the output end of the hydraulic cylinder 6. The first support plate 7 can be made of aluminum alloy. Aluminum alloy is lightweight while ensuring a certain strength, which facilitates flexible movement under the drive of the hydraulic cylinder 6. A scraper 8 is fixedly connected to the inner wall of the fixing block 5, and a quick-release assembly is provided on the side wall of the first support plate 7.

[0037] The quick-release assembly includes a second hollow plate 19, which can be made of engineering plastics such as nylon. Nylon has good mechanical properties, self-lubrication, and corrosion resistance. Its outer wall has low friction when sliding inside the first support plate 7. The outer wall of the second hollow plate 19 is slidably connected to the inside of the first support plate 7. A wrench 18 is rotatably connected to the top of the second hollow plate 19. The wrench 18 can be made of carbon steel and has undergone surface treatment. The carbon steel material provides the wrench 18 with the required strength and hardness to withstand the external forces during operation. A second fixing post 21 is fixedly connected inside the wrench 18. The second fixing post 21 can be made of stainless steel. The corrosion resistance of stainless steel ensures that it will not rust when used with other components or in mortar production environments. The outer wall of the second fixing post 21 is located inside the second hollow plate 19. A spring 20 is provided on the outer wall of the second fixing post 21. One end of the spring 20 is fixedly connected to the outer wall of the second fixing post 21, and the other end of the spring 20 is fixedly connected to a support post 22. The support post 22 can be made of carbon steel and has undergone surface treatment. Carbon steel provides the required strength for the support column 22, and surface treatment enhances its rust resistance. The outer wall of the support column 22 is slidably connected to the interior of the second hollow plate 19. A cleaning plate 9 is fixedly connected to the side wall of the first support plate 7. The cleaning plate 9 can be made of rubber. The rubber material is soft and has a certain degree of elasticity. When cleaning in contact with the scraper 8, it can effectively remove the mortar on the scraper 8 without damaging the scraper 8. The outer wall of the second hollow plate 19 is set inside the cleaning plate 9, and a support component is set inside the bracket 1.

[0038] Specifically, when operating the plastering mortar production feeder, firstly, the conveyor belt 2 starts, smoothly transporting the produced mortar away. At this time, the baffle 4 plays a crucial role, acting like a loyal guardian to effectively prevent accidental mortar spillage, ensuring the orderly transport process and environmental cleanliness. Next, the output end of the hydraulic cylinder 6 begins to exert force, pushing the first support plate 7 to move precisely. The first support plate 7 then drives the cleaning plate 9 to slide slowly along the side wall of the scraper 8, efficiently cleaning the scraper 8. When it is necessary to replace the cleaning plate 9, the operator only needs to pull the wrench 18. After the wrench 18 is stressed, it will drive the second fixed column 21 to move. During this process, the spring 20 will contract accordingly. The movement of the second fixed column 21 further drives the support column 22 to move. At this time, if the wrench 18 is pulled, the second hollow plate 19 can be smoothly brought out. Finally, the support column 22 is firmly secured inside the cleaning plate 9, thus cleverly achieving the effect of quickly replacing the cleaning plate 9, greatly improving the maintenance efficiency and overall operational stability of the equipment, and providing a strong guarantee for the continuous production of plastering mortar.

[0039] Reference Figure 1 and Figure 4The support components include a fixing plate 10, which can be made of stainless steel. Stainless steel has excellent corrosion resistance and can effectively resist corrosive factors such as water vapor and chemicals that may exist in the mortar production environment. The outer wall of the fixing plate 10 is fixedly connected to the inside of the bracket 1. A conveying pipe 23 is fixedly connected inside the fixing plate 10. The conveying pipe 23 can be made of high-strength polyvinyl chloride (PVC). PVC material has good corrosion resistance and a certain degree of flexibility, which can adapt to the complex layout inside the feeding machine. When conveying gas generated by the air compressor 3, it can effectively prevent gas leakage and ensure stable gas transmission to the inside of the connecting plate 15. The other end of the conveying pipe 23 is fixedly connected to the output end of the air compressor 3. One end of the conveying pipe 23 is fixedly connected to the inside of the connecting plate 15. A first hollow plate 11 is fixedly connected to the side wall of the fixing plate 10. The side wall of the first hollow plate 11 is fixedly connected to the side wall of the second support plate 13. The second support plate 13 can be made of carbon steel and is treated with rust prevention. Carbon steel provides sufficient strength and hardness to withstand the weight of components such as the motor 12 and the arc plate 17, as well as the forces generated during operation. The motor 12 is fixedly connected to the side wall of the second support plate 13, and the arc plate 17 is fixedly connected to the output end of the motor 12. The arc plate 17 can be made of cast iron. Cast iron has high strength and good wear resistance. When continuously rotating under the drive of the motor 12, it can withstand the forces and friction of components such as the first fixed column 16. The other side of the arc plate 17 is rotatably connected to the inner wall of the second support plate 13. The first fixed column 16 is rotatably connected to the inner wall of the arc plate 17. A connecting plate 15 is fixedly connected to one end of the first fixed column 16, and a rotating ball 14 is fixedly connected to the other end of the first fixed column 16. The rotating ball 14 can be made of wear-resistant alloy steel. Wear-resistant alloy steel has excellent wear resistance and good rotation performance. In the rotational connection with the side wall of the second support plate 13 and the side wall of the arc plate 17, it can rotate flexibly and is durable, reducing friction loss. The outer wall of the rotating ball 14 is rotatably connected to the side wall of the second support plate 13, and the side wall of the rotating ball 14 is rotatably connected to the side wall of the arc plate 17.

[0040] Specifically, in the operation mechanism of the plastering mortar feeding machine, the air compressor 3 plays a crucial role. Its output end, via the conveying pipe 23, precisely delivers gas to the interior of the first hollow plate 11, providing the power for subsequent actions. Simultaneously, the motor 12 starts operating, its output end driving the arc plate 17 to rotate stably. The rotation of the arc plate 17 causes the first fixed column 16 inside to rotate as well. The displacement of the first fixed column 16 then drives the connecting plate 15 to rotate within the arc plate 17. During this process, the rotating ball 14, as a key connecting component, functions on the side wall of the second support plate 13, ensuring a smoother and more stable rotation process, ultimately achieving precise control of the left and right rotation of the connecting plate 15. It is worth mentioning that the other end of the conveying pipe 23 is firmly fixed to the interior of the connecting plate 15, allowing the gas to flow and act in an orderly manner among the relevant components, working together to achieve the complex yet orderly workflow of the feeding machine, ensuring high efficiency and precision in the production process.

[0041] Working principle: When using the plastering mortar production feeder, the mortar is first transported away by the conveyor belt 2, and then blocked by the baffle 4 to prevent accidental leakage. Then, the output end of the hydraulic cylinder 6 drives the first support plate 7 to move. Subsequently, the first support plate 7 drives the cleaning plate 9 to slide against the side wall of the scraper 8. When replacing the cleaning plate 9, firstly, the wrench 18 is pulled. The wrench 18, under force, drives the second fixed column 21 to move. The movement of the second fixed column 21 causes the spring 20 to retract. Then, the movement of the second fixed column 21 moves the support column 22, and can pull the wrench 18 to pull out the second hollow plate 19. Then, the support column 22... The gas is inserted into the cleaning plate 9, which allows for quick replacement of the cleaning plate 9. Next, the air compressor 3 outputs gas into the first hollow plate 11 through the delivery pipe 23. Then, the motor 12 outputs gas to drive the arc plate 17 to rotate. The rotation of the arc plate 17 rotates the first fixed column 16 inside. Then, the first fixed column 16 moves and drives the connecting plate 15 to rotate inside the arc plate 17. Next, the rotating ball 14 is connected to the side wall of the second support plate 13, which allows it to rotate better and achieves the effect of controlling the left and right rotation of the connecting plate 15. The other end of the delivery pipe 23 is fixedly connected to the inside of the connecting plate 15.

[0042] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
