The filling and sealing machine adopts closed and semi-closed filling paste and liquid, no leakage in sealing, good filling weight and volume consistency, filling, sealing and printing are completed at one time, suitable for medicine, daily chemical, food, Product packaging in chemical and other fields. Such as: Pi Yanping, ointment, hair dye, toothpaste, shoe polish, adhesive, AB glue, epoxy glue, neoprene and other materials filling and sealing. It is an ideal, practical and economical filling equipment for pharmaceutical, daily chemical, fine chemical and other industries.
The work of the filling and sealing machine is determined by multiple parameters, and it is impossible to describe a filling and sealing machine with any single parameter. Shaft power, paddle displacement, pressure head, paddle diameter and filling speed are five basic parameters describing a filling and sealing machine.
The discharge volume of the blade is proportional to the flow rate of the blade itself, the power of the speed of the blade and the cube of the diameter of the blade. The shaft power consumed by filling is proportional to the specific gravity of the fluid, the power factor of the blade itself, the cube of the rotational speed and the fifth power of the diameter of the blade. Under the condition of certain power and blade form, the liquid discharge volume and pressure head of the blade can be adjusted by changing the matching of the diameter and rotation speed of the blade, that is, the large diameter blade is matched with a low rotation speed (guarantee the constant shaft power) irrigation The stern packer produces a higher flow action and a lower head, while the small diameter paddle with a high RPM produces a higher head and a lower flow action.
In the filling tank, the way to make the micelles collide with each other is to provide a sufficient shear rate. From the filling and sealing mechanism, it is because of the existence of the fluid velocity difference that the fluid layers are mixed with each other. Therefore, the fluid shear rate lhhaha620 is always involved in the filling process. Shear stress is a force that is the real cause of bubble dispersion, droplet breakup, etc. in filling applications. It must be pointed out that the shear rate at each point of the fluid in the entire stirred tank is not consistent.
Experimental studies have shown that, as far as the blade area is concerned, no matter what type of pulp, when the blade diameter is constant, the maximum shear rate and the average shear rate increase with the increase of the rotational speed. But when the rotation speed is constant, the relationship between the maximum shear rate and the average shear rate and the blade diameter is related to the pulp type. When the rotational speed is constant, the maximum shear rate of the radial blade increases with the increase of the blade diameter, while the average shear rate has nothing to do with the diameter of the blade. These concepts of shear rate in the paddle area require special care in the design of downscaling and scale-up filling and sealing machines. Compared with large tanks, small tank filling and sealing machines often have the characteristics of high rotation speed, small blade diameter and low tip speed, while large tank filling and sealing machines often have low rotation speed, large blade diameter and low blade tip speed. Features such as high tip speed.
