Desiccant packaging machine manufacturers explain in simple terms and analyze new technologies in the industry
Whether in the food, pharmaceutical or chemical industries, powdered materials are a headache in the packaging process. The powder packaging machine of Zhongshan Kenwei Electromechanical is a kind of packaging equipment widely used in food, medicine, chemical industry and other industries. In the packaging process of this kind of machinery, the most important thing is the quality of sealing. Especially the sealing process of the seal. Because the quality of the seal affects the quality of a product. What method does the professional powder packaging machine manufacturer use to ensure the sealing quality? The packaging of the mainstream powder materials currently on the market. Generally, the screw metering method is used, and this method can fully meet the requirements in terms of metering accuracy. But to achieve the perfect sealing effect. The difference is huge. There are many factors that affect the sealing quality. It is not necessary to say that the material fluidity bears the brunt. In terms of material fluidity, it is necessary to select the correct tray device for materials with different fluidity. For materials with good fluidity. The density of the tray added on the screw should be appropriate. If the density is too small, the phenomenon of dripping will occur. After the one-time feeding is completed, a small part of the material will continue to fall when the screw stops rotating. In this way, if the material is clamped when the sealing is closed, the sealing quality cannot be guaranteed. If the density is too high, the screw will lock up and cannot rotate. If the fluidity of the material is particularly good, and the use of the tray is ineffective, a blocking device needs to be added to ensure the sealing quality of the powder packaging machine. For materials with poor fluidity, it is not only necessary to choose suitable pallets. When necessary, a knocking device should be added to the bag maker. This device is auxiliary blanking. The process that the material falls from the screw to the hopper of the belt maker, and from the hopper to the bag. This device is required to assist in order to fall normally. It does not affect the sealing of powder packaging machine to achieve perfect sealing and effect. A headache for many manufacturers is the dust of the material. If the dust of the material is too large, there will be a backlash during the blanking process. This phenomenon will cause the product to be unsightly packaged, and more seriously, it may affect the quality of the bag seal. cause air leakage. Not only will it cause waste of packaging materials, but if the quality inspection is not strict, the products will flow to the market. It will cause great loss to customers. In view of this situation, powder packaging machine manufacturers have devoted themselves to researching how to shorten the distance from the discharge port to the bag. In this way, the traditional oblique screw feeding method should be abandoned. Straight screw is used. Because the reason for the counterattack is that the distance between the material leaving the screw and the semi-molded bag is too large. If a straight screw is used, the screw can be inserted directly into the former into the bag. The effect of reducing the drop is very obvious, which can greatly improve the sealing and effect of the product bag. Ensure that the sealing quality is tight and tight. At least there will be no shortened product shelf life due to air leakage. With this straight screw feeding method, the phenomenon of material backlash is solved, but the bag making specifications will be greatly limited. There is no good solution yet. But development is the process of finding problems and then solving them. Trusting in science and daring to innovate will eventually address such limitations. Focusing on the research and development of powder packaging machines for more than 20 years, we hope our efforts can solve your worries.
