Application of PLC control in blister packing machine PLC control of traction part According to the calculation, the working stroke of the CAM at the forming and heat sealing parts of the bubble cover is. Push movement time 0.5 seconds, far rest time 1.5 seconds, return movement time 0.5 seconds, near rest time 0.5 seconds. When the CAM of the shape and heat sealing part is in the state of push motion, the fixed mechanical gas clamp is loosened, the dynamic mechanical gas clamp is clamped, and the PVC sheet is pulled forward. This process is completed by PLC controller to control the opening and closing of the cylinder to complete. When the CAM is in the far rest position, that is, the whole machine is in the working state, the fixed mechanical gas clamp hand clamped, the dynamic mechanical gas clamp hand loosened, the work part began to work, including the completion of preheating, bubble forming and heat sealing. When the CAM is in the return movement state, the fixed mechanical

Trends in blister packaging equipment At present, China's pharmaceutical equipment market is still a buyer's market, every equipment manufacturer must design production equipment according to the market demand, according to the needs of customers. Therefore, driven by customer demand, blister packaging equipment in China will have the following trends China is a developing country with a large population. The national conditions determine that most of our pharmaceutical enterprises produce large quantities of products. In addition, through a gradual evolution in recent years, domestic pharmaceutical enterprises to survive, must have their own core products, the core products in general, larger output but the status quo of a pharmaceutical factory usually need to purchase a few production lines to meet the needs of the production, it shows that our equipment speed can't meet customer demand, So we must improve the level of automatic control of products, mechanical processing level

Blister packaging barrier testing At present, the overall barrier detection technology of packaging has been mature, but because the overall size of the bubble cover is very small, it is difficult to use general packaging overall detection accessories, and the strength of its aluminum foil layer is weaker than plastic, so the overall barrier detection technology has not been applied in the bubble cover packaging. However, in fact, due to the uniformity of the material adhesive coating amount, the heating and stretching rate of the material and the mechanical strength of aluminum foil, the oxygen and water vapor permeability of the actual bubble cover are higher than the calculated values based on the membrane sun barrier data. We have tested some drugs in the market using bubble cover package, and compared the actual barrier data of aluminum foil and PVC hard sheet or PVC/PVDC composite hard sheet obtained from some manufacturers, we found that although the barrier test data of packag

Requirements for packaging goods Packaging is one of the most important links in modern commodity production and marketing. The quality of packaging is directly related to the value of goods in the market circulation. With the development of market economy, people begin to realize that commodity packaging, as a visual communication tool, is not a dispensable thing, but the face of commodities, modern commodity packaging is becoming an indispensable part of commodities with its simple, clear shape. Packaging not only endows the product with unique personality, but also establishes a perfect visual image for the product. Drugs as a special commodity, and because of OTC drugs come on stage and parity, customize type of drugs the appearance of supermarket, more and more independent consumers to buy drugs, increasing understanding of the drug, the packing of the drugs have become consumers identify and purchase, how to win the favor of the consumers in numerous medicines, packaging design

The rationality of bubble cover packaging machine The evaluation of bubble cover packaging machine price and benefit is reasonable, should be considered from the following aspects (1) Technical performance, including production speed, finished product quantity, quality, yield, consumption of raw materials, power, degree of automation, safety and environmental protection. (2) Applicability: whether the complete equipment of the whole machine is complete, whether the interface device with expansion function is reserved, whether it has the same technical performance for multiple varieties and specifications, whether it is convenient to operate and replace the mold in use, how to meet the requirements of applicable environmental conditions, and how to adapt to the original and auxiliary materials. (3) the reliability of equipment is prone to failure in the process of work, whether at work requires constant adjustment, whether to remain unchanged for a long time continuously, the techni

Blister packaging machine cover material Aluminum foil is the main composition of the cover material, but also the packaging material with excellent barrier performance. The pinhole is the fatal defect of its penetrability. In the packaging, transportation and storage process of milk sheet, it is inevitable to rub and squeeze, so that the pinhole aperture or range of aluminum foil material increases, and there will be obvious creases. These places will cause the accelerated penetration of gas and water vapor, affecting the stability of aluminum foil material barrier performance. In general, two methods can be used to accurately assess the pinhole condition and barrier properties of cap material. One is to use the rubbing test instrument to apply the rubbing behavior that may be encountered in the circulation process of the cover mouth material, and the number of pinholes of the cover mouth material can be quickly tested by turpentine. The second is to test the barrier properties of t

Advantages and disadvantages of blister packaging Blister packaging is one of the most widely used and fastest developing flexible packaging materials in pharmaceutical industry, and also the main packaging form of solid drug dosage form in China. It has strong gas sealing, excellent moisture resistance, good oil resistance, drug resistance and solvent resistance, excellent resistance to oxygen, water vapor, carbon dioxide gas in the air, can meet the special requirements of drug bubble packaging. The use of aluminum foil as the substrate, the surface should be clean and shiny, good printing suitability, can be firmly coated with heat sealing coating, to ensure that the melt of the heat sealing coating, the substrate and bubble cover can be closely combined. Aluminum foil is non-toxic, tasteless, has excellent electrical conductivity and shading, has high moisture resistance, gas resistance and taste protection, can most effectively protect the packaged drugs, is a kind of packaging

Types and functions of packaging There are many kinds and varieties of articles, and the circulation conditions are also very different. Therefore, there are many kinds of packaging techniques, which are commonly used as follows (1) Moisture-proof packing Moisture-proof packaging is to use materials with a certain ability to isolate water vapor to seal the goods, isolate the impact of external humidity on the product, or add desiccant in the packaging container, in order to absorb the residual moisture in the package and the moisture permeated by the outside. (2) waterproof packaging Waterproof packaging is a kind of protective measures taken to prevent the deterioration and damage of contents caused by water intrusion into the packaging container. (3) rust proof packaging Anti-rust packaging is to prevent the corrosion of metal items in the packaging and take certain protective measures of packaging. (4) Mildew proof packaging Mildew proof packaging is a kind of protective me

Blister packaging machine feeding filling Elastic yellow hose is stainless steel filament winding dense hose, commonly used ten to make the capsule aluminum bubble cover packaging, the inner diameter of the tube is slightly larger than the outer diameter of the capsule, can ensure that the tube only storage single row of capsules. Attention should be paid to ensure that the hose does not bend, so as to ensure the smooth flow of the cavity in the tube. Usually, with the help of the vibration of the whole machine, the hose shakes itself, so that the cavity can be stored in the lower exit. There are many forms of spring mechanism, can use ratchet, intermittent toggle spring opening and closing, and ensure that each lift once, only release a capsule, can also use the gap reciprocating motion opening and closing spring, release a capsule at a time. In the mechanism setting, there is usually a row of hoses with an intermittent mechanism to ensure linkage. Inspection using artificial or pho

The role of bubble cover packaging machine Blister packaging The original blister packaging was mainly used for drug packaging. At that time, in order to overcome the disadvantages of inconvenient use of glass bottles, plastic bottles and other bottled drugs, large investment in packaging production line, and the need for dose packaging, small pill packaging is increasing, so in the 1950s, bubble packaging appeared and has been widely used. Later, through in-depth research and continuous improvement of blister packaging materials, technology and machinery, great progress has been made in packaging quality, speed and economy. Nowadays, in addition to drug tablets, colloidal and suppository packaging, it is also widely used in the packaging of food and daily necessities. If the use of automatic packaging machine, but also improve production efficiency, reduce costs. A blister package for a drug, which can protect the product from moisture, dust, pollution, theft and damage, prolong the
