Description

Technical Field

[0001] The invention relates to the technical field of watercolor pen packaging, in particular to an automatic packaging line for watercolor pen bags. Background Art

[0002] Watercolor pens are a widely used painting tool. They are deeply loved by painting enthusiasts and students because of their rich colors and ease of use. There are many types of watercolor pens, which can be divided into wax and water-based according to the properties of the ink. Wax watercolor pens have the characteristics of bright colors and adjustable line thickness, which are suitable for drawing lines and large areas of color blocks; water-based watercolor pens are softer and easy to mix, suitable for expressing delicate color transitions and gradient effects. Their pen bodies are usually made of plastic, and there are corresponding color labels on the pen caps so that users can quickly identify and select the required colors. Watercolor pen bags are a packaging form that combines multiple watercolor pens in a bag for sale. This packaging method is not only convenient for consumers to buy and carry, but also conducive to merchants' display and sales.

[0003] In the field of watercolor pencil packaging, manual packaging has long been the mainstream method. Operators must complete a series of steps, including unpacking the bag, opening it, inserting the pencil into the bag, and sealing it. This method is labor-intensive and extremely dependent on manpower. As labor costs continue to rise, production costs for companies also rise. Moreover, manual operation speed is limited, making it difficult to achieve a qualitative leap in output efficiency and meet the current market's urgent demand for efficient production.

[0004] Some companies have tried to use heat sealing technology to achieve automatic packaging, but the heat sealing process consumes a lot of heat energy, and energy consumption remains high. This not only increases production costs, but also goes against the current green and energy-saving production concept. The process is complicated, and equipment debugging and maintenance are difficult. If you are not careful, problems such as loose sealing and deformation may easily occur, resulting in unstable sealing quality, seriously affecting product quality and image, and frequent after-sales problems, which bring many troubles to companies. Summary of the Invention
