[0002] In the emery cloth processing industry, the supply and mixing of raw materials are key links in the production process. The traditional emery cloth raw material feeding method often adopts one-time feeding or intermittent feeding, which has many shortcomings. First, one-time feeding or intermittent feeding is difficult to ensure the continuity and stability of raw materials, which easily leads to material shortage or surplus in the production process, affecting production efficiency and product quality. Secondly, the traditional feeding method lacks sufficient stirring and mixing of raw materials, which makes it easy for raw materials to be uneven during the mixing process, further affecting the quality and performance of emery cloth. In addition, with the continuous development of emery cloth processing technology, the requirements for the supply and mixing of raw materials are getting higher and higher. Existing emery cloth raw material feeding devices are often complex in structure and cumbersome in operation, which are difficult to meet the needs of modern production. Therefore, it is of great significance to develop an emery cloth raw material feeding device that can realize continuous circulation feeding of raw materials and sufficient stirring and mixing, in order to improve the emery cloth processing efficiency and ensure product quality.

For ordinary technicians in this field, the specific meanings of the above terms in the utility model can be understood according to specific circumstances.

[0023] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Emery cloth is also called iron emery cloth or diamond emery cloth. Emery cloth is made by bonding abrasives (sand grains) evenly to a solid cloth base with a binder. It is mainly used to polish rust, paint or burrs on the surface of metal workpieces and polish the surface. It can also be used to polish non-metallic materials such as bone products. The abrasives in emery cloth include artificial corundum, artificial corundum, corundum, silicon, quartz, pumice, iron oxide, etc. According to the size of the abrasive, emery cloth can also be divided into different numbers, that is, the raw materials of emery cloth are divided into two categories: solid powder and liquid.

[0025] Example 1

[0026] like Figure 1-4 As shown, a circulating feeding device for abrasive cloth raw materials includes a solid material storage bin 3, a liquid material storage bin 4, and also includes a primary premixing bin 5 and a secondary mixing bin 6. The discharge ends of the solid material storage bin and the liquid material storage bin are connected to the feed end of the primary premixing bin. The discharge end of the primary premixing bin is connected to a circulating feeding pipe 1, on which a circulating pump 10 is installed. The other end of the circulating feeding pipe 1 is connected to the feed inlet of the primary premixing bin to form a premix circulating feeding channel. The discharge end of the liquid material storage bin is also connected to a circulating feeding pipe 2, on which a circulating pump 2 10 is installed. The other end of the second channel is connected to the feed port of the liquid material storage bin to form a liquid material circulation supply channel; the circulation supply pipeline one is connected to the feed end of the secondary mixing bin through the branch pipeline one, and the circulation supply pipeline two is connected to the feed end of the secondary mixing bin through the branch pipeline two, and control valves 13 are installed on both branch pipelines one and two; in addition, it also includes a frame 1, on which a two-layer platform 2 is installed, a solid material storage bin 3 and a liquid material storage bin 4 are installed on the two-layer platform, and a first-level premixing bin 5 is installed below the two-layer platform. The installation of the two-layer platform and a reasonable equipment layout make the entire batching system compact in structure and easy to operate.

[0027] There are multiple secondary mixing bins installed in parallel. By installing multiple secondary mixing bins in parallel, the system can process more materials at the same time, thereby significantly improving production efficiency. This design enables the system to cope with larger-scale production needs while maintaining efficient and stable operation.

[0028] Among them, the circulating feed pipe 1 and the circulating feed pipe 2 adopt a sandwich structure pipe 17, and a heating device for the internal material is installed in the interlayer 18 of the sandwich structure pipe. The circulating feed pipes 1 and 2 adopt a sandwich structure and have a built-in heating device. The heating device includes a circulating pump 19 and a heating box 20 for circulating the heat flow (water, oil), so that the material can maintain an appropriate temperature during the transportation process to prevent the material properties from changing due to temperature changes. This helps to ensure the accuracy of the raw material ratio and the mixing uniformity, and improve product quality.

[0029] The first-level premixing bin and the second-level mixing bin include a bin body 21, wherein a stirring mechanism is installed in the middle position of the bin body, the stirring mechanism includes a stirring shaft 24 rotatably installed in the first-level premixing bin and the second-level mixing bin, and a stirring blade 22 is installed around the shaft on the stirring shaft. A driving motor 23 for driving the stirring shaft to rotate is installed outside the first-level premixing bin and the second-level mixing bin, wherein a feed port 26 and a return port 27 are provided on the top of the bin body, and a discharge port 25 is provided at the bottom of the bin body. The stirring mechanism installed in the first-level premixing bin and the second-level mixing bin can ensure that the materials are fully stirred during the mixing process, further improving the mixing uniformity. The installation of the driving motor makes the mixing process more automated, reducing the difficulty and error of manual operation.

[0030] A weighing device 16 is installed at the bottom of the solid material storage bin, liquid material storage bin, first-level premixing bin, and second-level mixing bin to detect changes in the internal material capacity so as to replenish the material in time. The installation of the weighing device 16 enables the system to monitor the changes in the material capacity in each storage bin and mixing bin in real time, so as to replenish the material in time and ensure the continuity and stability of the production process.

[0031] A semi-finished material storage bin is installed between the first-level premixing bin and the second-level mixing bin. The feed end of the semi-finished material storage bin is connected to the discharge end of the first-level premixing bin, and the discharge end of the semi-finished material storage bin is connected to the feed end of the second-level mixing bin.

[0032] A metering pump 11 and a mass flow meter 12 are installed between the discharge end of the liquid material storage bin and the feed ends of the primary premixing bin and the secondary mixing bin, so as to accurately control the amount of liquid added and ensure the accuracy of the ratio.

[0033] like Figure 2As shown, as another embodiment, the discharge end of the solid material storage bin is also connected to a circulating feed pipe three 14, a powder delivery pump 15 is installed on the circulating feed pipe three, and the other end of the circulating feed pipe three is connected to the feed port of the solid material storage bin to form a solid material circulating feed channel; the circulating feed pipe three is connected to the feed end of the secondary mixing bin through a branch pipe three, and a control valve is also installed on the branch pipe three to realize the full material circulation supply of solid powder and liquid material.

[0034] Example 3: Figure 5 In this embodiment, two solid material storage bins and two liquid material storage bins are installed in parallel, which ensures that one of the bins is loaded and the other is fed at any time. By installing two solid material storage bins and two liquid material storage bins in parallel, the continuity of loading and feeding is ensured, thereby improving production efficiency.

[0035] Based on the above designs, this scheme firstly significantly improves the accuracy of raw material proportioning and the uniformity of mixing. By carrying out the initial mixing ratio in the primary premixing bin and accurately proportioning in the secondary mixing bin according to the process and product requirements, the raw materials are fully mixed and evenly distributed. This helps to improve the quality and performance stability of the emery cloth and reduce the quality problems caused by uneven raw material proportioning; secondly, the system has a high degree of automation and reduces the dependence on manual operation. Through the automatic batching system, the automatic transportation, proportioning and mixing of raw materials are realized, which reduces the tediousness and errors of manual operation. This not only improves production efficiency, but also reduces labor costs, creating greater economic benefits for the enterprise. In addition, the full-circulation design of the system effectively prevents material waste. Through the setting of the circulating feed pipeline and the circulating pump, the recycling of raw materials is realized, avoiding waste or residual materials generated in the traditional batching process. This not only improves the utilization rate of raw materials and reduces production costs, but also helps to reduce environmental pollution and achieve green production; finally, the system has high flexibility and scalability. According to different processes and product requirements, the proportioning parameters of the primary premixing bin and the secondary mixing bin can be flexibly adjusted to meet different production needs. At the same time, the system can also be expanded according to the production scale to adapt to larger-scale production needs. In summary, the automatic batching system for solid and liquid raw materials of abrasive cloth provided by the utility model has significant beneficial effects such as improving the accuracy of raw material ratio, reducing dependence on manual operation, preventing material waste, and flexible scalability, which provides strong support for the production of the abrasive cloth processing industry.
