First, automatic shrink packaging machine profile
Microwave automatic shrink packaging machine, can use PE, PET, POF, PP and other materials, the microwave oven for packaging, instead of carton packaging. In order to replace the imported equipment products, it will also be the development direction of the alternative means of domestic carton packaging.
The use of microwave automatic shrink packaging machine, can be packaged goods delivery, promotion, sealing, hot air vortex circulation heating, strong cold shrinkage process, machine, electricity, gas integration. High efficiency and good quality.
Microwave oven full-motion heat shrink packaging machine realizes that the packaged goods are shrink-wrapped with heat-shrinkable film on six sides, which can replace cartons, reduce the use of paper to protect the forest and reduce the cost of packaging; heat-shrinkable film can be recycled and reused, and environmental protection is saved. Features such as moisture-proof, dust-proof and shock-proof are better than carton packaging, which increases the intuitive sense of the goods and facilitates and promotes product sales.
This machine is also suitable for other products such as air conditioners, televisions, refrigerators, hardware, electricity, machinery and equipment, ceramics and other industries that need six-pack packaging industry automatic production line packaging.
Second, the characteristics of domestic similar shrink packaging machine
The automatic six-sided shrink-wrapping machine for smaller size articles (L*W*H approximately less than 500*300*300) has been produced in China and is mainly used for packaging in the pharmaceutical, healthcare, and food industries. Larger-sized articles (L*W*H larger than 500*300*300) are shrink-wrapped, and the four-sided shrinkage has been used in beverage beer and other industries. However, six-sided heat-shrinkable packaging of larger-sized articles is still relatively rare in the country. The reason for this is that the six-sided heat-shrinkable packaging of large-sized articles has its own unique problems and difficulties. .
Smaller-sized items (L*W*H less than 500*300*300) are fully automatic, six-sided heat shrinkable packages. Due to the small size and high height of the items, the upper and lower cover films are commonly used, and the three sides are sealed and cut. Constant temperature heating, strong wind cooling process, packaging quality and efficiency are more mature.
However, the full-size six-sided heat-shrink packaging of larger-sized articles (L*W*H > 500*300*300) has higher height dimensions due to the larger size of the articles. If the upper and lower cover films are also used, three-side seals are cut. The process has many problems to achieve, mainly including:
1. Due to the large size, it is difficult to cover the film evenly when it is covered with a film. The thin film has a large area and the film is very easy to wrinkle, which affects the effect of the next process.
2. As the height is relatively high, the stroke of the seal cutter is large, and it is easy to tear and wrinkle the film. The packaging effect is poor and the quality assurance is difficult to guarantee.
3, due to the relatively large size of the packaging, uneven heating and shrinkage is more serious, prone to shrinkage, uneven shrinkage, too much local shrinkage, shrinkage, packaging effect is difficult to guarantee.
4. It is difficult to handle the remaining four sharp corners after three-sided sealing, which affects the packaging effect and appearance quality.
Third, the characteristics of the shrink packaging machine
In order to overcome the above problems, after repeated studies and experiments, we found new solutions:
1. Using a pre-made packaging bag, bagging the bagged article - sealing and closing the mouth - constant temperature heating - strong cooling and shrinking process.
2. Prefabricated packaging bags have taken into account such factors as tensile and wrinkle resistance, non-uniform shrinkage resistance, water vapor emissions, and four sharp corners, which have created conditions for high-quality closure and shrinkage.
3. The bag mouth sealing and closing device adopts advanced industrial automation technology and mechanical and electrical integration technology to solve the problems of sealing and trimming quality difficult to guarantee, operator safety is not guaranteed, the bag seals when the seal is cut, the bag edge is cut continuously, the adhesion is fixed, etc. Series problems.
4. Solve the problems that the bottom of the bag is pulled and wrinkled due to the transport, the uneven heating, uneven cooling and non-uniform shrinkage due to the large and heavy objects.
5. Optimize electronic self-control hardware and software design. Temperature control, time control, speed control, and motion control are all completed by high-quality industrial control computers. Each parameter undergoes repeated research, testing, and improvement until the effect is good.
6. Optimize the design of mechanical moving parts to completely solve the problems of easy cutting, deformation, cutting, and failure of sealing and cutting tool holders.
7. The use of automation and moving parts products from the industry's top brands has solved problems such as efficiency, reliability, stability, durability, and continuous workability.
