(1) Automatic line grinding and polishing machine The automatic line grinding and polishing machine is an equipment that has been developed in the past two years to achieve mechanized grinding and polishing of lines. It can realize line shaping, grinding and polishing, side grinding and polishing of lines, and assembly line production, thereby improving line production efficiency and product quality, improving the working environment of employees, and reducing labor intensity. This is a breakthrough and innovative technology in the field of stone deep processing, which has been gradually promoted and applied in the domestic stone industry. The automatic line machine breaks through the limitation that the previous automatic line grinding and polishing machine can only polish and polish natural stone materials. It can polish and polish artificial granite materials, which takes the technology forward a big step. At present, many domestic stone production enterprises have purchased a fully automatic liner, which has its unique technical advantages and innovation:
1. All the processes of forming, side thickness setting, polishing, and side polishing complete the line, and directly produce the finished product. 2. The combined circular saw blade rough machining + forming wheel fine milling modeling mode has successfully solved the disadvantages of similar equipment such as low forming efficiency, high production cost, and rough forming surface, making the formed lines more delicate and precise. The combined diamond saw blade not only inherits the advantages of traditional diamond saw blades with high modeling efficiency, but also exerts the advantages of the overall shape of the forming knife. Combining the technical advantages of the two, improves the efficiency of line forming. The combination of saw blades of different diameters is used to form lines of different shapes, and the processed parts are rough processed. Combination saw blade shape diagram
3. The equipment only needs one thick (60#) and one thin (120#) forming milling wheel to complete the finishing milling of the line, which reduces 2 milling wheels compared with the same period last year, which can achieve the purpose of reducing production costs. 4. Low breakage rate. Because the saw blade is used for forming, the contact surface is small and the cutting is sharp, so the pressure on the stone and the forming wheel to the line is reduced. In particular, it has a great protective effect on product materials that are easy to break and small lines, reducing the rate of product damage and improving the economic benefits of enterprises.
5. Low conversion cost, suitable for small batch line production. The circular saw blades with different shapes and diameters are combined to form various lines and curves. When the shape of the processed line changes, you only need to re-adjust the saw blade sequence and combine the saw blades to achieve the purpose of changing the line shape.
6. The operation is flexible and convenient, without the need for professional operators. The use of advanced programmable control technology overcomes the shortcomings of similar equipment such as simple control system, fixed lifting speed of the forming polishing wheel, and constant pressure, making the operation simpler and more convenient, and the product quality more stable. The polishing system and lifting system of the automatic line grinding and polishing machine adopts an advanced numerical control system, which controls the lifting of the polishing head by driving a high-precision stepping motor. This kind of CNC lifting system can set different polishing grinding head speed and polishing grinding head lifting speed according to the structure, thickness, density, gloss of the stone and different abrasive sharpness. With the cooperation of linear guide rail and precision screw, it is precise Drop to the workpiece on the polished surface, and continue to polish the workpiece according to the set pressure.
Each group of motors of the automatic line grinding and polishing machine is equipped with a speed sensor, which can detect the pressure and changes on the surface of the polished workpiece at any time, and can feedback to the polishing grinding head CNC lifting system at any time according to the pressure change. The numerical control system adjusts the descending speed of the polishing head in time, so that the rotation speed of the polishing head is always in the optimal range, greatly reducing the consumption and waste of the polishing head, and making the surface polishing of the line more delicate and higher. 7. There is an intelligent operating system that can realize man-machine dialogue. The system consists of a programmable controller and a touch screen. According to the shape, material, density and hardness of the stone line to be processed, the working procedure of each group of polishing grinding head can be formulated in accordance with the density and mesh number of the polishing grinding head. When the polishing head is working, once the surface pressure of the polished workpiece changes, it can automatically adjust the rotation speed and descending speed of the polishing head, so that the polishing head is always in the best working state during polishing. 8. Stable transmission system. The entire assembly line has a set of stable and high-precision conveying devices, which can ensure that the lines to be polished accurately and continuously enter the polishing work area, so that the polishing head can accurately polish and polish the lines. 9.
