[0002] In the modern packaging industry, efficient and high-quality packaging equipment has always been the goal pursued by enterprises. With the continuous growth of market demand and the increasing requirements of consumers for product packaging, the traditional packaging machine laminating device has gradually exposed some shortcomings. On the one hand, in the traditional product packaging process, the diamond laminating sheet is usually set symmetrically, but because there are lines on both sides, pinholes are easily generated. In addition, the laminating device of the traditional packaging machine rarely achieves integrated plastic sealing, the sealing effect is unstable, and it is prone to offset and other problems, affecting the appearance and sealing of the product. The consistency of the sealing and cutting of the traditional device needs to be improved. Often, a second cutting is required after the plastic sealing, which cannot well meet the requirements of large-scale production. On the other hand, the processing of materials before packaging is also crucial. Some processed materials will also have a common problem of agglomeration before packaging, which will affect the product quality and packaging effect. The traditional feeding device may lack effective stirring of the material when adding the material, resulting in the material agglomeration cannot be handled in time, thus affecting the quality of the product before packaging.
