Description

Technical Field

[0001] The invention belongs to the technical field of film-covered packaging, and in particular relates to a device for synchronously wrapping and sealing multiple goods. Background Art

[0002] Film packaging is an important packaging technology, which is mainly used to provide products or goods with protection, moisture-proof, dust-proof, and other functions. The following is a detailed explanation of film packaging:

[0003] I. Definition

[0004] Film packaging is a packaging method that places products or goods in an appropriate position and then covers them with one or more layers of plastic film. Its purpose is to provide a certain degree of protection and safety for the goods through the covering of plastic film.

[0005] 2. Features

[0006] Protectiveness: Film packaging can protect the goods to a certain extent, preventing them from being affected by moisture, pollution, damage, etc.

[0007] Moisture-proof and dust-proof: By covering with plastic film, it can effectively isolate external moisture and dust, keeping the goods dry and clean.

[0008] Aesthetics: The surface of the packaged product after lamination is smoother and brighter, which improves the appearance quality and grade of the product.

[0009] Environmental protection: With the development of technology, the materials used in film packaging are becoming more and more environmentally friendly, reducing pollution to the environment.

[0010] The main disadvantages of film packaging are summarized and expressed in points according to different aspects:

[0011] During the operation of film packaging, if there is a problem of misalignment or incomplete folding, it will bring a series of disadvantages. The following is a detailed analysis of these problems:

[0012] 1. Misalignment of film packaging

[0013] Affecting aesthetics: Misalignment will cause the packaging to have an uneven appearance, lose its original aesthetic effect, and affect the overall image of the product.

[0014] Reduced protection: Misalignment may result in the packaging not fully covering the product, thereby reducing its ability to protect the product from the outside environment.

[0015] Increased costs: Misalignment can lead to wasted packaging materials, increasing production costs. At the same time, additional labor and time may be required to correct the misalignment, further increasing costs.

[0016] Reduced production efficiency: In automated production lines, misalignment may cause machine downtime or require manual intervention for adjustments, thus reducing production efficiency.

[0017] 2. Folding is not in place

[0018] Impact on packaging stability: Improper folding will result in an unstable packaging structure, which may easily deform or be damaged during transportation or storage.

[0019] Reduced sealing: Failure to fold properly may result in a loose packaging seal, making the product vulnerable to external environmental influences such as moisture, dust, etc.

[0020] Increased risk of damage: Inadequate folding may make the packaging more susceptible to damage when subjected to external forces, thus affecting the safety and quality of the product.

[0021] Reduced user experience: For consumers, packaging that is not folded properly may leave a bad impression on them and reduce their trust and satisfaction with the product.

[0022] 3. Cargo misalignment and shaking

[0023] Tearing or damage of the film: The goods may rub against the film during the shaking process, especially when the film material is thin or of poor quality, it is easy to tear or break at the corners or stress points, thus losing its due protective function.

[0024] Reduced sealing: The shaking of goods may cause gaps or openings in the originally sealed film packaging, especially at the seal or edge of the film, which will expose the goods inside the packaging to the external environment and increase the risk of moisture, contamination or damage.

[0025] Shifting or collision of goods: Shaking of goods may cause the goods to move inside the package and collide with the inner wall of the package or other goods, which may not only damage the goods themselves, but also produce additional pressure on the film, causing deformation or damage to the film.
