Description

TECHNICAL FIELD

[0001] The utility model relates to the related technical field of boxing equipment, especially to prevent product slip boxing machine. BACKGROUND

[0002] In the modern packaging industry, paper box forming equipment is widely used in the automatic boxing process of products. Under normal circumstances, such equipment will pull up the unformed paperboard and initially form a frame, then place it on the conveying line for transportation, and complete the product loading, paper box bottom packaging and top sealing operation at each station. However, in some existing paper box forming equipment, there is a significant technical problem: when the stacked or bulk products are loaded into the paper box frame that is not completely sealed, the product may slip or fall due to the unsealed side of the paper box. This not only affects production efficiency, but also may cause product quality damage, and even cause equipment operation failure. Therefore, an equipment that can close the side of the paper box during the boxing process is urgently needed to effectively prevent the product from slipping from the paper box opening.

[0003] The paper box forming equipment in the prior art usually includes a paper box suction mechanism, a product conveying mechanism, a box bottom packaging mechanism and a box top packaging mechanism. Although these devices can complete the basic paper box forming and packaging functions, they often ignore the optimization design of the boxing sequence when handling slippery or stacked products, especially the closing of the side of the paper box before the product is loaded. In addition, the existing box top packaging mechanism lacks effective control of the state of the side of the paper box during the packaging process, which may cause the product to slip laterally after being loaded, thereby affecting the packaging effect and stability.

[0004] To solve the above problems, a new type of anti-product slip boxing machine is needed, which improves the function of the box top packaging mechanism to close the side of the paper box before the product is loaded, and maintains this state during the subsequent packaging process to ensure that the product is reliably confined inside the paper box. This design not only avoids the risk of product slipping, but also improves the stability and reliability of the boxing process, meeting the needs of the modern packaging industry for efficient and accurate production.
