Abstract
Description
Technical Field
[0001] This utility model belongs to the field of food packaging film processing technology, and in particular relates to a plasma surface activation treatment device for food packaging film. Background Technology
[0002] Common food packaging film materials are mostly non-polar polymer materials with low surface energy and poor hydrophilicity. This makes it difficult for inks, adhesives or functional coatings to adhere firmly in subsequent processes such as printing, lamination and coating, which can easily lead to problems such as ink detachment and delamination, affecting the packaging's aesthetics, sealing and functionality (such as barrier and freshness preservation).
[0003] To solve this problem, the industry needs to activate the surface of packaging films, which requires activation equipment. However, existing plasma surface activation equipment generates a lot of heat during operation. If the heat cannot be dissipated in time, it will continue to accumulate high temperature. The key components of the equipment will age faster and degrade in performance due to high temperature, and may even experience short circuits, burnout and other failures, shortening the equipment life and increasing maintenance costs. Therefore, we propose a plasma surface activation treatment equipment for food packaging films. Utility Model Content
[0004] The purpose of this invention is to provide a plasma surface activation treatment device for food packaging film. By incorporating a heat dissipation mechanism, specifically, coolant carries away heat from the outer surface of the plasma generator through a cooling pipe, and finally discharges through a drain hose. A delivery pipe transfers air to the inside of the linkage frame, which then transfers the air to the spray nozzle. The spray nozzle blows the air towards the outer surface of the vacuum chamber, thereby achieving external cooling and promptly removing heat from the vacuum chamber. This prevents continuous heat accumulation, reduces the impact of high temperatures on the internal equipment, and extends the equipment's lifespan. It solves the problem that existing plasma surface activation treatment equipment generates excessive heat during operation, which cannot be dissipated in time, leading to continuous high temperatures. This causes key components to age faster, experience performance degradation, and even short circuits or burnouts due to high temperatures, shortening equipment lifespan and increasing maintenance costs.

Specifically, coolant carries away heat from the outer surface of the plasma generator through a cooling pipe and is finally discharged through a drain hose. A delivery pipe transfers air to the inside of the linkage frame, which then transfers the air to the spray nozzle. The spray nozzle blows the air towards the outer surface of the vacuum chamber, thereby achieving external cooling. This promptly removes heat from the vacuum chamber, preventing continuous heat accumulation, reducing the impact of high temperatures on the internal equipment, and extending the equipment's lifespan.

The plasma generator 13 generates heat during operation, and coolant is introduced through the inlet hose 323, which transfers the coolant. The coolant flows into the cooling tube 322, which contacts the outer surface of the bottom of the plasma generator 13. The coolant carries away the heat from the outer surface of the plasma generator 13 through the cooling tube 322 and is finally discharged through the drain hose 324. At the same time, the electric push rod 313 is activated to increase or decrease the extension length of the output rod, thereby controlling the distance between the linkage frame 311 and the vacuum chamber 12. After the linkage frame 311 moves to the predetermined position, the second air pump is activated to transfer air into the delivery pipe 312. The delivery pipe 312 transfers the air into the linkage frame 311, and the linkage frame 311 transfers the air to the paint spray head. The paint spray head blows the air toward the outer surface of the vacuum chamber 12, thereby achieving the effect of external cooling.
