Filling and sealing machine has good cost performance

In order to meet the market demand, China's filling and sealing machine industry is actively getting rid of the image with a large number and low technical content, and is developing in the direction of multi-functionality, modularization, intelligent control and high precision. Food industry products need packaging, and the quality of packaging and printing directly affects the quality, grade and market sales of food industry products. Although the filling and sealing machine can not determine the inherent quality of the food, good packaging can ensure and extend the quality and life of the food, extend the shelf life of the food, and facilitate carrying and transportation.

In order to meet the market demand, China's filling and sealing machine industry is actively getting rid of the image with a large number and low technical content, and is developing in the direction of multi-functionality, modularization, intelligent control and high precision. Food industry products need packaging, and the quality of packaging and printing directly affects the quality, grade and market sales of food industry products. Although the filling and sealing machine can not determine the inherent quality of the food, good packaging can ensure and extend the quality and life of the food, extend the shelf life of the food, and facilitate carrying and transportation.

Excellent packaging can earn a reputation for the product, establish a brand, prevent counterfeiting, and provide convenience for consumers to choose goods. With the further adjustment of the product structure of the food industry and the upgrading and upgrading of the products, the requirements for packaging and decoration printing and packaging are correspondingly higher.

From the mechanism of filling and sealing machine, it is because of the difference of fluid velocity that the fluid layers are mixed with each other. Therefore, the filling process always involves the fluid shear rate lhhaha620. Shear stress is a force that is the real cause of bubble dispersion and droplet breakage in filling applications. It must be pointed out that the shear rate of each point of the fluid in the entire agitation tank is not uniform.

The discharge volume of the blade is proportional to the flow rate of the blade itself, the primary of the blade rotation speed and the cube of the blade diameter. The shaft power consumed by the filling is proportional to the specific gravity of the fluid, the power level of the blade itself, the third of the rotational speed and the fifth power of the blade diameter. In the case of a certain power and blade form, the blade discharge volume (Q) and the indenter (H) can be adjusted by changing the matching of the diameter (D) and the rotational speed (N) of the blade, that is, the large diameter blade is matched. Filling and sealing machines with low speed (with guaranteed shaft power) produce higher flow and lower heads, while small diameter blades with higher speeds produce higher heads and lower flow effect.

In the filling and filling machine filling tank, in order to make the micelles collide with each other, it is effective to provide a sufficient shear rate. From the filling and sealing mechanism, it is precisely because of the difference in fluid velocity that the fluid layers are mixed with each other. Therefore, the filling process always involves the fluid shear rate lhhaha620. Shear stress is a force that is the real cause of bubble dispersion and droplet breakage in filling applications. It must be pointed out that the shear rate of each point of the fluid in the entire agitation tank is not uniform.

Experimental studies have shown that for the blade area, the maximum shear rate and the average shear rate increase with increasing speed when the blade diameter is constant regardless of the type of slurry. However, when the rotational speed is constant, the relationship between the maximum shear rate and the average shear rate and the diameter of the blade is related to the slurry type. When the rotational speed is constant, the maximum shear rate of the radial blade increases as the diameter of the blade increases, and the average shear rate is independent of the diameter of the blade. These concepts regarding the shear rate of the paddle zone require special care in the shrinking and amplifying design of the filling and sealing machine.

Combined with the actual situation of domestic filling and sealing machine, the filling and sealing machine has a good cost performance, can meet the requirements of enterprises, and has broad application prospects in many industries such as pharmaceutical industry, health care products and alcohol. System hardware configuration for programmable controller selection, I/O point definition, and selection and placement of major components. Through the analysis of the system control process, the system programming is designed, and the corresponding system software is compiled to realize the online weighing control process.

Based on the design of system software and hardware, the control theory of online weighing control system is analyzed, and the control method adopted by the system is briefly discussed. The mathematical model and transfer function analysis are established according to the control system, and the method is adopted. The system model shows that the simulation curve and related data verification system have good stability, achieve the expected design purpose, and realize the online weighing control function.
