DETAILED DESCRIPTION
[0028] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.
[0029] Embodiment 1
[0030] like Figure 1-6As shown, a continuous automatic grinding device provided in this embodiment includes a mixing hopper 1, an automatic grinding barrel 2 and a screening and conveying unit 3, the outlet of the mixing hopper 1 is connected to the inlet of the automatic grinding barrel 2, the screening and conveying unit 3 includes a conveying part 31 for conveying workpieces and a screening part 32 for screening out the grinding material, the outlet of the automatic grinding barrel 2 is connected to the inlet of the conveying part 31, the outlet of the conveying part 31 is connected to the inlet of the next process, and the screening part 32 is arranged on the conveying part 31. First, through the organic combination of the mixing hopper and the automatic grinding barrel, the continuous supply of the grinding raw material is realized. The mixing hopper is used as a storage and mixing unit for the raw materials, and its outlet is directly connected to the inlet of the automatic grinding barrel, which ensures the stable and continuous supply of the grinding raw materials, thereby avoiding the problem of low production efficiency caused by intermittent feeding. It is important that the screening and conveying unit is introduced into the technical solution of this embodiment. This design not only realizes the continuous transmission of the workpiece after grinding, but also effectively separates the grinding material through the screening part. The screening and conveying unit includes a conveying part and a screening part, wherein the conveying part is responsible for continuously conveying the ground workpiece to the next process, while the screening part is arranged on the conveying part to screen the workpiece and separate the ground material from the workpiece. This structural design greatly improves the continuity and automation of the grinding process and reduces the need for manual intervention. This tightly connected design effectively eliminates gaps and waiting times in the production process and realizes the continuity of the production process. In summary, this technical solution effectively solves the problem that the intermittent operation of conventional automatic grinding devices is not suitable for continuous production by integrating multiple key technical features, and provides an innovative solution for fields such as the manufacture of composite electrode materials.
[0031] In order to simplify the structure of the above-mentioned screening and conveying unit, specifically, the conveying part 31 in this embodiment adopts the structure of a conveyor belt, and the screening part 32 is a plurality of openings opened on the conveyor belt, and the openings are evenly distributed on the conveyor belt, and the size of the openings is larger than the abrasive and smaller than the workpiece, so that the abrasive other than the workpiece can fall from the openings on the conveyor belt, which plays a role in removal and screening. Preferably, in order to prevent the workpiece from falling on both sides of the conveyor belt 31 during transportation, inclined baffles 33 are provided on both sides of the conveyor belt 31.
[0032] Specifically, it also includes a workpiece conveying unit 4, an abrasive conveying unit 5 and a grinding liquid filling port 6. The outlet of the workpiece conveying unit 4, the outlet of the abrasive conveying unit 5 and the grinding liquid filling port 6 are arranged at the entrance of the mixing hopper 1. The above-mentioned conveying units all adopt conventional conveyor belt transmission. The workpiece conveying unit is responsible for conveying the composite electrode material to be ground obtained from the previous process, the abrasive conveying unit is responsible for conveying abrasives such as zirconium oxide and aluminum oxide, and the grinding liquid filling port is responsible for adding grinding liquids such as mineral oil and surfactants. First, the workpiece conveying unit ensures the continuous supply of raw materials and the continuity and stability of the production process. Without manual intervention, the workpiece can be continuously transported to the mixing hopper, thereby avoiding downtime waiting time and improving production efficiency. Secondly, the setting of the abrasive conveying unit ensures the continuous supply of abrasives and ensures the stability and uniformity of the grinding process. This continuous supply design not only improves production efficiency, but also reduces fluctuations in the production process and ensures the stability of product quality. Finally, the setting of the grinding liquid filling port achieves lubrication and cooling effects during the grinding process. The addition of nozzles can ensure that the grinding fluid is evenly sprayed during the grinding process, improving grinding efficiency and product quality. Timely filling of grinding fluid effectively prevents overheating and wear of the equipment and extends the service life of the equipment. The mixed workpiece and abrasive are ground in the mixing hopper while being discharged from the outlet at the bottom of the mixing hopper. The outlet size can be adjusted to facilitate the control of the discharge speed.
[0033] Preferably, a nozzle is provided at the grinding liquid filling port 6, and the grinding liquid filling port can adjust the flow rate through a valve and is equipped with a pressurizing device. A nozzle is provided at the grinding liquid filling port, and this design provides an important guarantee for the further optimization of the automatic grinding device. First, the setting of the nozzle realizes the uniform spraying of the grinding liquid, ensuring the lubrication and cooling effect during the grinding process. Uniform spraying can ensure that the temperature of each part is balanced during the grinding process, effectively reducing wear and heat accumulation, and extending the service life of the equipment. Secondly, the addition of the nozzle improves the utilization rate of the grinding liquid and avoids liquid waste and pollution. Through precise control, it can be ensured that the amount of grinding liquid is moderate, avoiding excessive waste of liquid and cleaning work.
[0034] Preferably, the automatic grinding barrel is equipped with gears on the outside. Through gear transmission, the automatic grinding barrel can achieve high-speed rotation, and the speed is continuously adjustable from 0 to 300 r / min. The actual speed can be adjusted according to the size of the workpiece. A threaded structure 21 for conveying is provided on the inner side of the automatic grinding barrel 2. The threaded structure can be designed in a spiral or threaded shape so that the material can be conveyed and mixed along the direction of the threaded structure in the barrel. The angle and pitch of the thread can be adjusted according to the properties of the material and the needs of conveying to achieve the best conveying effect. First, the setting of the threaded structure realizes the uniform conveying and mixing of the material during the grinding process. The threaded structure can convey the material from one end of the barrel to the other end, ensuring the uniform force and mixing effect of the material during the grinding process, and improving the efficiency and stability of the grinding. Secondly, the addition of the threaded structure also reduces the energy consumption and wear of the equipment. Among them, the thread pitch in the threaded structure is 5-20 mm, the width of the thread is 3-30 mm, and the height of the thread is 2-10 mm.
[0035] In order to ensure that the workpiece and the abrasive can move smoothly from the feed port to the discharge port, preferably, the automatic grinding barrel 2 has an inclination angle of 5-15° with the horizontal plane and is inclined toward the discharge port. A moderate inclination angle helps to promote uniform mixing and flow of the abrasive and the workpiece in the automatic grinding barrel. In this embodiment, the inclination of the automatic grinding barrel 2 is adjusted by providing a vertically movable cylinder mechanism 22 on one side and a hinge 23 on the other side. If the inclination angle is too small, it will not have a diversion effect. If the inclination angle is too large, the workpiece will be in the grinding barrel for too short a time and will not be fully ground. Through this inclined design, the abrasive and the workpiece can flow along the inclined direction of the grinding barrel, thereby effectively improving the uniformity and mixing effect during the grinding process. This ensures that the raw materials are fully ground and mixed, thereby improving the uniformity and quality stability of the product.
[0036] Preferably, it also includes a return material conveying unit 7 and a grinding material recovery pool 8, the return material conveying unit 7 is arranged below the screening conveying unit 3, and the grinding material recovery pool 8 is located at the outlet side of the return material conveying unit 7. This preferred technical solution further optimizes the production process and resource utilization of the automatic grinding device. First, the return material conveying unit is arranged below the screening conveying unit, which can effectively recover the grinding material dropped from the screening conveying unit, and the grinding material is transported back to the grinding material recovery pool through the return material conveying unit, thereby improving the production efficiency and raw material utilization rate. Further, the grinding material conveying unit 5 connects the grinding material recovery pool 8 and the entrance of the mixing hopper 1. Preferably, the grinding material conveying unit 5 adopts a vertical spiral feeding form, and the grinding material in the grinding material recovery pool is transported to the top through the internal spiral component, and then enters the entrance of the mixing hopper 1. This setting ensures the continuous supply and stable transportation of the grinding material during the grinding process. By being located between the recovery pool and the mixing hopper, the grinding material conveying unit can effectively transport the recovered grinding material back to the mixing hopper for use, thereby ensuring the continuity and stability of the grinding process and improving the production efficiency and product quality.
[0037] The outer material of the automatic grinding barrel 2 can be a metal material such as stainless steel, aluminum alloy, etc. Preferably, an inner lining layer is provided on the inner side of the automatic grinding barrel 2, and the material of the inner lining layer is Teflon or silicone. First of all, Teflon and silicone have excellent wear resistance and corrosion resistance. These materials have excellent high temperature resistance and chemical stability, can effectively resist wear and corrosion, extend the service life of the grinding barrel, and reduce the maintenance cost of the equipment. In addition, Teflon and silicone materials also have good wear resistance, which can protect the workpiece from being scratched during grinding, effectively reduce the wear and energy consumption of the equipment, reduce production costs, and improve product quality and production efficiency.
[0038] Preferably, a vibration motor is installed at the bottom of the mixing hopper 1. First, the setting of the vibration motor can effectively promote the uniform mixing of the raw materials. Through the vibration of the vibration motor, the raw materials can be preliminarily fully mixed and evenly distributed in the mixing hopper, ensuring the consistency and quality stability of the mixture and improving the quality of the product. In addition, the setting of the vibration motor can also improve the discharge efficiency of the mixing hopper. Through the vibration of the vibration motor, the raw materials can be smoothly discharged from the mixing hopper, reducing the residue and waste of raw materials in the hopper and improving the production efficiency and utilization rate of the equipment.
